    CONCRETE COLUMN WITH FOOT PLATE AND METHOD FOR MANUFACTURING A CONCRETE COLUMN WITH FOOT PLATE
    TECHNICAL DOMAIN
    The invention relates to a concrete column with a base plate and a method for manufacturing a concrete column with a base plate.
    BACKGROUND ART US 4 330 970 describes a concrete column provided with a pin with which the concrete column can be attached to an element by means of sleeves which are located in the element. A sleeve and a pin placed therein are attached to each other by pouring concrete into the space between the sleeve and pin. US 4 330 970 has the problem that the fixation via sleeve and pin only achieves sufficient rigidity after the concrete has dried between sleeve and pin. Drying up the concrete can delay the progress of a construction project. US 4 938 635 describes a concrete beam with similar end pieces at each end. Each end piece comprises a rectangular plate which is perpendicular to the concrete beam's longitudinal axis. The plate comprises at least four openings, and normally one opening per corner. Plates of adjacent beams can be connected through these openings to an assembly of several concrete beams. US 4 938 635 has the problem that the fixing mechanism of the concrete beams via the openings in the slabs may be insufficient to provide support for high-weight concrete beams fixed in this way. It also requires some effort to correctly align the concrete beams with respect to each other.
    It is an object of the present invention to find a solution to at least one of the aforementioned problems.

    DETAILED DESCRIPTION
    Unless defined otherwise, all terms used in the description of the invention, including technical and scientific terms, have the meaning as generally understood by those skilled in the art of the invention. For a better assessment of the description of the invention, certain terms are explicitly explained or defined.
    The terms "includes", "comprising", and "provided with" are synonyms and are inclusive or open terms indicating the presence of what follows, and which do not exclude or prevent the presence of other components, features, elements, members, steps , known from or described in the prior art.
    A first aspect of the invention relates to a concrete column (5), the dimension of which in the longitudinal direction, being the length dimension (16), is considerably larger than the dimensions in the transverse direction, being the width dimension (14) and the depth dimension (15), and which concrete column (5) is provided with a reinforcement (7, 8, 9), wherein a rectangular base plate (6) is connected to the reinforcement (7, 8, 9) at the height of the lower surface (18) of the concrete column ( 5) oriented in the transverse direction of the concrete column (5), of which foot plate (6) the dimensions are oriented in the transverse direction of the concrete column (5), being the width dimension (19) and the depth dimension (20) of the foot plate (5) 6) are larger than the width dimension (14) and depth dimension (15) of the concrete column (5), and which base plate (6) comprises a portion that completely overlaps the bottom surface (18) and a portion that does not have the bottom surface (18) overlaps, and that the base plate (6) includes external openings (13) located in the portion of the base plate (6) that does not overlap with the bottom surface (18).
    The term "concrete column" (5) in this text refers to a column (5) or pillar made of concrete. In a building or building structure, concrete columns (5) usually act as upright load-bearing structures that carry loads mainly through axial compression. The cross-section of concrete columns (5) can take many polygonal forms, such as, for example, a square, a rectangle, a hexagon, etc. The concrete column (5) according to the present invention can be obtained by curing any concrete composition from the prior art technology that is suitable for obtaining concrete with a sufficient compressive strength to be used in a building or building construction. The concrete columns (5) according to the present invention preferably have a sufficient compressive strength, sufficient resistance to moisture, frost and salt, a smooth aspect, and a uniform color.
    The concrete column (5) according to the present invention comprises a reinforcement (7, 8, 9). The term "reinforcement" is a term known in the art and refers to a reinforcing element that is provided in concrete to reinforce it and to make it more resistant to, for example, compressive or tensile forces to which the concrete is subjected. When a reinforcement (7, 8, 9) is present in concrete, "reinforced concrete" is typically used. The reinforcement (7, 8, 9) according to the present invention can comprise any configuration known in the state of the art and can for instance be provided in the form of rods, nets, cables, gratings, etc. and can furthermore comprise any material known in the prior art, such as metal, e.g. steel, fiberglass, plastic, etc. The cheapest form of reinforcement (7, 8, 9) is formed by iron-based reinforcement. The reinforcement (7, 8, 9) preferably comprises steel, stainless steel and / or iron.
    The concrete column (5) according to the present invention is connected to its reinforcement (7, 8, 9) at the level of the lower surface (18) to a rectangular base plate (6). Joining the base plate (6) to the reinforcement (7, 8, 9) of the concrete column (5) is an efficient way of firmly attaching the base plate (6) to the concrete column (5). The foot plate (6) can for instance be manufactured from a plastic or a metal. The base plate (6) preferably comprises steel, stainless steel and / or iron. Any method of adhesion that allows an adhesion between the materials of the base plate (6) and the reinforcement (7, 8, 9) can be used for this. When both base plate (6) and reinforcement (7, 8, 9) are made of steel, stainless steel and / or iron, the base plate (6) and reinforcement (7, 8, 9) can be attached to each other by a welding process. A welding process is well known in the art and is a fastening technique that can be carried out with great flexibility. As a welding process, any welding process known as known in the art can be used, including arc welding, electrical resistance welding, autogenous welding, pressure welding, spot welding and beam welding. In another embodiment, the combination of the reinforcement (7, 8, 9) and the base plate (6) can be produced in one piece.
    The base plate (6) has a limited length dimension (21) relative to the length dimension (16) of the concrete column (5). The width dimension (19) and the depth dimension (20) of the base plate (6) are larger than the width dimension (14) and the depth dimension (15) of the concrete column (5). The foot plate (6) comprises a portion that completely overlaps the bottom surface (18) and a portion that does not overlap with the bottom surface (18). The foot plate (6) includes external openings (13) located in the portion of the foot plate (6) that does not overlap with the bottom surface (18). Elongated structures can be provided through the external openings (13), such as, for example, pins or rods (3), which may or may not be provided with a screw thread. The external openings (13) are intended to provide a connection between the concrete column (5) and another structure (1) by means of pins or rods (3) provided on this other structure (1). The external openings (13) make it possible to quickly and securely secure the concrete column (5) to another structure (1). In addition, the use of base plate (6) and external openings (13) is a cost-efficient way to attach a concrete column (5) to another structure (1). In addition, the concrete column (5) can be aligned quickly and efficiently through the external openings (13).
    According to a possible embodiment of the first aspect of the invention, the concrete column (5) is provided with sleeves (12) directed in the longitudinal direction of the concrete column (5) and ending on the lower surface (18) of the concrete column (5), and comprising the base plate (6) internal openings (22) which are in line with the sleeves (12).
    The concrete column (5) according to the present invention is provided with tubes (12) directed in the longitudinal direction of the concrete column (5). These sleeves (12) are located internally in the concrete column (5) and extend at least to the bottom surface (18) of the concrete column (5). Each tube (12) is arranged in a longitudinally oriented cavity in the concrete column (5), the dimensions of the cavities being adjusted to the dimensions of the tubes (12). The sleeves (12) are hollow bodies with a limited diameter relative to the width dimension (14) and depth dimension (15) of the concrete column (5). Preferably the sleeves (12) extend from the bottom surface (18) via a substantial length in the longitudinal direction of the concrete column (5). This substantial length is preferably at least 40 times greater than the diameter of a pin or rod (11) to which a tube (12) wants to be connected, and preferably at most equal to the length dimension (16) of the concrete column (5) . The sleeves (12) are preferably straight structures. The sleeves (5) may, for example, occur as a hollow cylinder or a hollow beam. The sleeves (12) are preferably hollow cylinders. The tubes (12) can for instance be made of plastic or metal. The attachment between the tubes (12) and the pins or rods (11) of another construction (1) takes place by pouring concrete into the space between the pins or rods (11) and the interior of the tubes (12). In addition, the inside of the sleeves (12) is preferably provided with a ribbed pattern. This ribbed pattern ensures good adhesion between sleeves (12) and pins or rods (11) with which the sleeves (12) want to be connected. Such pins or rods (11) are, after all, preferably embodied with a ribbed outer surface, so that the ribbed structures of both sleeves (12) and pins or rods (11) can interlock for good adhesion.
    The combination of internal openings (22), external openings (13) and tubes (12) is intended to provide a connection between the concrete column (5) and another structure (1), provided with pins or rods (3, 11) to this other construction (1). The additional provision of internal openings (22) in the base plate (6) and sleeves (12) in the concrete column (5) on the one hand, and additional pins or rods (11) in a structure (1) on the other, is recommended in situations wherein the concrete column (5) must withstand large loads. Indeed, in the latter embodiment, a load exerted on the concrete column (1) can also be transferred to the structure (1) by means of the sleeves (12) and the associated pins or rods (11). The presence of the fixing mechanism via the external openings (13) in the base plate (6) ensures on the one hand that the hardening of the concrete between pins or rods (11) and tubes (12) does not have to be awaited before the concrete column (5) can be subjected to a light load, without the need for external means for supporting or supporting the concrete column (5). On the other hand, the fastening mechanism via the external openings (13) in the base plate (6) ensures that the concrete column (5) can be aligned quickly and efficiently. Because drying of the poured concrete does not have to be awaited, an important time saving can be obtained with construction work. When the concrete is hardened between pins or rods (11) and tubes (12), the concrete column (5) can be subjected to greater loads.
    According to an embodiment of the first aspect of the invention, an element (10) is attached to the portion of the base plate (6) that does not overlap with the bottom surface (18) of the concrete column (5). In another embodiment, a plurality of elements (10) are adhered to the portion of the base plate (6) that does not overlap with the bottom surface (18) of the concrete column (5). The element (10) can take any shape. In a preferred embodiment, the element (10) consists of three plate-shaped structures attached to each other, two of which are shorter plate-shaped structures and one longer plate-shaped structure. The shorter plate-shaped structures in that embodiment are vertically oriented and attached to the base plate (6) at a distance from each other. The longer plate-shaped structure in that embodiment is oriented horizontally and is attached to the two shorter plate-shaped structures on the side opposite the side to which they are connected to the base plate (6). The element (10) can for instance be made of a plastic or a metal. The element (10) preferably comprises steel, stainless steel and / or iron. When both the element (10) and the base plate (6) are made of steel, stainless steel and / or iron, they can be attached to each other by a welding process. For advantages of a welding process as well as suitable welding processes, reference is made to the text above. The element (10) acts as an additional reinforcement of the base plate (6) which can be used if desired to transfer large loads from the concrete column (5) proportionally via the base plate (6) to another structure (1).
    According to an embodiment of the first aspect of the invention at least one sleeve (12) extends at each corner of the bottom surface (18) of the concrete column (5), the sleeves (12) being symmetrically arranged at different angles with respect to each other . This position of tubes (12) relative to each other ensures a proportional distribution of load and forces when the concrete column (5) is provided by means of bars (11), which bars (11) are provided on another construction (1), on this other construction (1) is confirmed.
    According to an embodiment of the first aspect of the invention, the base plate (6) does not overlap at the corners of the base plate (6) with the bottom surface (18) of the concrete column (5) and is per corner of the base plate (6) at least one external opening (13) is present, the external openings (13) of the different angles being arranged symmetrically with respect to each other. Such placement of external openings (13) in the base plate (6) ensures a proportional distribution of load and forces when the base plate (6) and consequently the concrete column (5) are provided by means of bars (3), which bars (3) are provided on another structure (1) is attached to this other structure (1). In a preferred embodiment, in addition, the shortest distance from a corner of the base plate (6) to the shortest corner of the concrete column (5) is the same for each corner of the base plate (6). This further promotes the proportional distribution of load and forces when mounted between concrete column (5) and a structure (1).
    According to an embodiment of the first aspect of the invention, the concrete column (5) is attached to a structure (1) by means of external rods (3) and, where present, internal rods (11) anchored in the structure (1), the external rods (3) running through the external openings (13) of the foot plate (6) and being fixed to the foot plate (6) at the height of these external openings (13) by means of fastening means (4), and, where present, the internal rods (11) pass through the internal openings (22) of the base plate (6) into the sleeves (12) of the concrete column (5), and concrete is present between the internal rods (11) and the interior of the sleeves (12). The structure (1) is preferably provided with an anchor plate (2) which is adapted to adjust the mutual positioning of the external rods (3) and, where present, internal rods (11), and to adjust the rods (3 , 11) in place. The anchor plate (2) is a plate which is located on a surface of a structure (1) and is fixed to this structure (1). The anchor plate (2) comprises openings for the bars (3, 11) which the plate (2) is to receive. The diameter of these openings is adjusted to the diameter of the external bars (3), or external bars (3) and internal bars (11) that run through these openings. The anchor plate (2) can for instance be made of plastic or metal. The anchor plate (2) preferably comprises steel, stainless steel and / or iron. The structure (1) is preferably a concrete structure. The structure (1) can comprise a reinforcement, which reinforcement can consist of plastic and metal, and preferably comprises steel, stainless steel and / or iron. When the structure (1) comprises a reinforcement, the anchor plate (2) is preferably connected to the reinforcement of the structure (1). For example, an anchor plate (2) made of steel, stainless steel and / or iron can be connected to a reinforcement made of steel, stainless steel and / or iron via a welding process. The internal bars (11) and external bars (3) can for instance be made of plastic or a metal. Preferably the internal bars (11) and external bars (3) comprise steel, stainless steel and / or iron. Internal bars (11) and external bars (3) are anchored in a structure (1). Preferably, internal bars (11) and external bars (3) are anchored to the reinforcement of the structure (1) when the structure (1) comprises a reinforcement. The dimensions of the external bars (3) are adjusted to the dimensions of the external openings (13) and vice versa. The dimensions of the internal bars (11) are aligned with the dimensions of the internal openings (22) and the sleeves (12), and vice versa. The diameter of the internal bars (11) should be smaller than the diameter of the inside of the tubes (12), so that there is room to provide concrete between internal bars (11) and tubes (12). The diameter of the internal bars (11) is preferably at least 26 mm and at most 95% of the diameter of the inside of the tubes (12), and more preferably at most 90%. Multiple types of fasteners (4) are possible for fixing the external bars (3) to the base plate (6) at the height of the external openings (13). For example, an adhesive or glue can be used as a fastening means, or a mechanical fastening means (4) can be used, such as, for example, a nut (4). With a nut (4) it is necessary that the external rods (3) are provided with a thread. The fastening means (4) is preferably a nut (4) and the external rods (3) are provided with a thread. This is an extremely suitable way to quickly connect the base plate (6) and external bars (3) and to be able to align the concrete column (5) quickly and efficiently.
    According to an embodiment of the first aspect of the invention, the fixing means (4) are located at both ends of the external openings (13) of the base plate (6). The fastening means (4) is preferably a nut (4) and the external rods (3) are provided with a thread. The presence of fasteners at both ends of the external openings (13) is extremely suitable for adjusting and aligning the orientation of the concrete column (5) when this concrete column (5) is connected to a structure (1). After all, with load, good orientation and alignment are important in order to transfer pressure loads and / or tensile loads in a balanced way between structural structures. It should be noted that, in the presence of internal openings (22) in the base plate (6) and sleeves (12) in the concrete column (5) on the one hand, and internal rods (11) in a structure (1) on the other, the adjustment orientation and alignment is simplified by mounting the concrete column (5) through its internal openings (22) and sleeves (12) with internal rods (11) of the structure (1), since this attachment is already for rough orientation and ensures alignment of the concrete column (5).
    According to an embodiment of the first aspect of the invention, the depth dimension (15) of the concrete column (5) relates to the width dimension (14) of the concrete column (5) according to a ratio of 1: 1 to 4: 1, and the length dimension (16) of the concrete column (5) to the depth dimension (15) of the concrete column (5) according to a ratio of 1.5: 1 to 75: 1. The manufacture of concrete columns (5) within the boundaries of said ratios between width dimension (14), depth dimension (15) and length dimension (16) makes it possible to efficiently match the dimensions of the concrete columns (5) to the needs of building projects, such as the need to withstand loads on loaded concrete columns (5).
    According to an embodiment of the first aspect of the invention, the width dimension (19), depth dimension (20) and length dimension (21) of the base plate (6) relate to the width dimension (14), depth dimension (15) and length dimension (16), respectively. of the concrete column (5) according to a ratio of 2: 1 to 1: 1, 2: 1 to 1: 1 and 1: 850 to 1:10, respectively. It follows that the base plate (6) is a flat structure that mainly extends according to its width dimension (19) and its depth dimension (20). According to the above ratios, the base plate (6) is at least as wide and as deep as the concrete column (5), which can contribute to the stability of a connection between concrete column (5) and a structure (1) according to embodiments of the present invention.
    According to an embodiment of the first aspect of the invention, one or more surfaces of the concrete column (5) located along the longitudinal direction of the concrete column (5) are provided with one or more consoles (29), which consoles (29) appear as a local extension of said surfaces in the transverse direction of the concrete column (5). The consoles (29) can therefore be seen as local protrusions of the concrete column (5). The consoles (29) serve to support another structural structure, such as, for example, a concrete beam or pillar, or a concrete slab. The distance at which a console (29) locally lengthens said surface is at least 20% and preferably at least 25% of the width dimension (14) or depth dimension (15) of the corresponding surface of the concrete column (5). The dimension of a console (29) along the longitudinal direction of the concrete column (5) is at least 20% and preferably at least 25% of the width dimension (14) or depth dimension (15) of the corresponding surface of the concrete column (5) . In a preferred embodiment, the distance at which a console (29) locally extends a longitudinal surface of the concrete column (5) according to the transverse direction of the concrete column (5) is at least 20 cm, and preferably at least 25 cm, and the dimension of a console (29) along the longitudinal direction of the concrete column (5) is at least 20 cm, and preferably at least 25 cm. The above-mentioned guidelines for the dimensions of a console (29) give rise to a console (29) that can provide sufficient support and support for supporting another structural structure. In addition to consoles (29), other adjustments to the concrete column (5) are possible depending on the connection with other structural structures. The concrete column (5) can for instance comprise a recess over its longitudinal direction, into which recess a plate, such as, for example, a wall panel, can be received. All other possible adjustments in this context, as known to those skilled in the art, are possible.
    According to an embodiment of the first aspect of the invention, at least on one surface of the concrete column (5) located along the longitudinal direction of the concrete column (5), several consoles (29) are provided, the distance between the consoles (29) being in said longitudinal direction is a multiple of 20% to 85% of the size (14, 15) of said surface area measured in the transverse direction of the concrete column (5). Depending on the surface located along the longitudinal direction of the concrete column (5), to which the brackets (29) are attached, the dimension measured in the transverse direction corresponds to the width dimension (14) or the depth dimension (15) of the concrete column (5) ). The aforementioned distance between the consoles (29) is sufficient to meet all building requirements. For example, a concrete plate can be fitted between successive consoles (29). In a preferred embodiment, the dimension (14, 15) of said surface in the transverse direction is between 30 cm and 90 cm, and the above-mentioned distance between the brackets (29) is a multiple of 20 cm, and preferably a multiple of 25 cm.
    A second aspect of the invention relates to a method for manufacturing a concrete column (5) provided with a base plate (6), which method comprises at least the following steps: - manufacturing a concrete column (5) comprising a reinforcement (7, 8 , 9); - the manufacture of a foot plate (6); - attaching the base plate (6) to the reinforcement (7, 8, 9); wherein before or after attaching the foot plate (6) to the reinforcement (7, 8, 9) external openings (13) are provided in the vicinity of the circumference of the foot plate (6).
    Preferably, the base plate (6) is wider and deeper than the concrete column (5), and the base plate (6) is attached to the reinforcement (7, 8, 9) of the concrete column (5) such that the circumference of the base plate (5) 6) and the external openings (13) provided therein are outside the concrete column (5). The dimension (16) of the concrete column (5) in the longitudinal direction is preferably considerably larger than the dimensions (14, 15) of the concrete column (5) in the transverse direction. For the manufacture of the concrete column (5), a concrete composition is poured into a mold or formwork, the dimensions of which are adjusted to the desired dimensions of the final concrete column (5). A reinforcement (7, 8, 9) is also provided in this mold before or during the pouring of the concrete composition. A mold or counterform is a preformed device that can comprise a substance. The mold holds the concrete composition in place during hardening of the concrete composition into a concrete column (5). The base plate (6) is preferably made of steel, stainless steel and / or iron. The foot plate (6) can be manufactured by transferring molten steel, stainless steel and / or iron by any suitable casting technique, as known in the art, into a mold for shaping the foot plate (6). Any method of attachment that allows an adhesion between the materials of the base plate (6) and the reinforcement (7, 8, 9) can be used to attach the base plate (6) to the reinforcement (7, 8, 9). When both base plate (6) and reinforcement (7, 8, 9) are made of steel, stainless steel and / or iron, the base plate (6) and reinforcement (7, 8, 9) can be securely attached to each other by a welding process . The external openings (13) can be provided, for example, by drilling openings (13) in the base plate (6). Carrying out the method gives rise to a concrete column (5) which can be quickly and firmly connected to another structure (1) by means of the external openings (13) of the base plate (6).
    According to an embodiment of the second aspect of the invention, the method further comprises the steps of arranging at least one cavity extending in the longitudinal direction of the concrete column (5), and of arranging a sleeve (12) in each cavity extending in the longitudinal direction of the concrete column (5), and before or after attaching the base plate (6) to the reinforcement (7, 8, 9), internal openings (22) are provided in the base plate (6) in line with the positions of said tubes (12) in the concrete column (5). The provision of at least one cavity extending in the longitudinal direction of the concrete column (5) can be effected, for example, by drilling a cavity in the concrete column (5), which may or may not be cured. The provision of a sleeve (12) in each cavity extending in the longitudinal direction of the concrete column (5) can be effected, for example, by striking these sleeves (12) in the cavities, for example with a hammer. In another embodiment, the tubes (12) are already provided in the mold before or during the pouring of the concrete composition. As a result, the provision of cavities in the concrete column (5) and the installation of sleeves (12) in these cavities are obtained in one step. It must be ensured here that the flow of the concrete composition into the tubes (12) is avoided. This can be achieved when the tubes (12) run over the entire longitudinal direction of the mold and over the entire longitudinal direction of the concrete column (5). The internal openings (22) in the base plate (6) can be provided, for example, by drilling openings (22) in the base plate (6). The combination of internal openings (22) and tubes (12) provides an additional way to securely connect a concrete column (5) to another structure (1).
    According to an embodiment of the second aspect of the invention, in a next step the external openings (13) and, where present, internal openings (22), of the base plate (6) over external rods (3), and respectively, where present , slid over internal bars (11) provided with a structure (1), and the external bars (3) are then attached to the base plate (6), and, where present, internal bars (11) are connected to sleeves (12) of the concrete column (5). The bars (3) which end up in the external openings (13) of the foot plate (6) can be attached to the foot plate (6) by applying any fastening means (4), such as, for example, an adhesive or glue, or a mechanical fastener (4). The bars (3, 11) are elongated structures that are anchored in a structure (1). The bars (11) which end up in the internal openings (22) and consequently the tubes (12) are preferably adhered to the concrete column (5) by pouring concrete into the space between the bars (11) and the interior of the sleeves (12). Through the external openings (13), optionally combined with internal openings (22) and tubes (12), a firm connection is obtained between the concrete column (5) and another structure (1), by means of pins or rods (3, 11) provided for this other construction (1). The additional provision of internal openings (22) in the base plate (6) and sleeves (12) in the concrete column (5) on the one hand, and additional pins or rods (11) in a structure (1) on the other, is recommended in situations wherein the concrete column (5) must withstand large loads.
    A third aspect of the invention relates to the use of a method according to the second aspect of the present invention for obtaining a concrete column (5) according to the first aspect of the present invention. For the characteristics and advantages of such a concrete column (5), reference is made to the above description of the first aspect of the present invention.
    In the following, the invention is described on the basis of non-limiting examples illustrating the invention, which are not intended or may be interpreted to limit the scope of the invention. EXAMPLES: EXAMPLE 1:
    Figure 1 shows a possible embodiment of a concrete column (5) with base plate (6), according to embodiments of the present invention. The base plate (6) of the example is positioned symmetrically with respect to the bottom surface (18) of the concrete column (5). The external openings (13) are positioned symmetrically with respect to each other. The placement of foot plate (6) as well as external openings (13) is extremely suitable for fixing the concrete column (5) to external bars (3) that are anchored in a structure (1). The stated structure of the concrete column (5) with base plate (6) makes it possible to transfer forces and loads proportionally from the concrete column (5) to a structure (1). Figure 2 shows in detail a possible embodiment of the attachment between concrete column (5) with base plate (6) and a structure (1). The external bars (3) are attached to the base plate (6) by means of nuts (4) that are placed at both ends of the external openings (13) (only the nuts (4) at one end of the openings (13) are visible in Figure 2), which allows a good orientation and alignment of the concrete column (5) with respect to the structure (1). In Figure 3 the internal components of the concrete column (5) are shown according to a possible embodiment of the present invention. The reinforcement (7, 8, 9), to which the base plate (6) is attached by means of a welded connection, comprises both main reinforcements (7), standing reinforcement brackets (8) and horizontal reinforcement brackets (9). EXAMPLE 2:
    Figure 4 shows a possible embodiment of a concrete column (5) with base plate (6), according to embodiments of the present invention. In comparison with Example 1, the concrete column (5) with base plate (6) of Example 2 additionally includes tubes (12) in the concrete column (5) and internal openings (22) in the base plate (6) which are in line with these tubes ( 12). The concrete column (5) is shown in solid form, as a result of which the reinforcement (7, 8, 9) in the concrete column (5), as well as the sleeves (12) in the concrete column (5) which are in line with the internal openings (22) of the foot plate (6) are not visible. The base plate (6) in Figure 4 is positioned symmetrically with respect to the bottom surface (18) of the concrete column (5). The external openings (13) are arranged symmetrically with respect to each other and the internal openings (22) are also arranged symmetrically with respect to each other. The latter also points to sleeves (12) in the concrete column (5) that are placed symmetrically with respect to each other. The location of the base plate (6) in relation to the concrete column (5), as well as the location of the tubes (12), internal openings (22) and external openings (13), is extremely suitable for fixing the concrete column (5). ) to internal bars (11) and external bars (3) anchored in a structure (1). The stated structure of the concrete column (5) with base plate (6), as shown in Figure 4, allows transfer of forces and loads proportionally from the concrete column (5) to a structure (1). The additional provision of sleeves (12) and internal openings (22), as well as internal bars anchored in a structure (1), makes it possible to carry heavy loads on the concrete column (5). EXAMPLE 3:
    Figures 5 to 7 show a detailed view of a possible embodiment of the attachment between concrete column (5) with base plate (6) and a structure (1), according to embodiments of the present invention. The concrete column (5) with base plate (6) of Figures 5 to 7 is analogous to that shown in Figure 4, with the exception of the presence of an element (10), which supports the concrete column (5) on the base plate (6). 6) is attached. The element (10) is a reinforcement of the base plate (6) which contributes to a high load of the concrete column (5) that a load of the column (5) can be transferred proportionally to the structure (1). The structure (1) is provided with an anchor plate (2), internal bars (11) and external bars (3). The external bars (3) are provided with a thread. The external rods (3) are attached to the base plate (6) by means of nuts (4) that are placed at both ends of the external openings (13), which ensures a good orientation and alignment of the concrete column (5) with respect to the construction (1) makes possible. It can be seen in Figure 6 that the reinforcement (7, 8, 9) comprises both main reinforcements (7), standing reinforcement brackets (8) and horizontal reinforcement brackets (9). When comparing Figure 7 with Figure 6, it can be deduced that the internal bars (11) are located in the sleeves (12) to a considerable distance. The adhesion between internal bars (11) and the interior of the tubes (12) is achieved by concrete poured into the space between them. EXAMPLE 4:
    Figure 8 is a representation of a possible embodiment of a concrete column (5) provided with consoles (29), according to embodiments of the present invention. Both the concrete column (5) and the brackets (29) have beveled corners (28). From an aesthetic point of view, beveled corners (28) are preferable to non-beveled corners. The surfaces at the top of the brackets (29) are flat and lying oriented, and are therefore provided for supporting another structural structure, such as, for example, a concrete beam or beam.
