    [0002] CONTINUOUS MANUFACTURING MACHINE OF PRETENSED PLATES OF CONCRETE AND COMPONENT OF SUCH MACHINE.
    [0003]
    [0004] OBJECT OF THE INVENTION
    [0005]
    [0006] The invention, as expressed in the wording of the present specification, refers to a machine for the continuous production of pre-stressed concrete plates, which has novelty characteristics that will be described in detail later on.
    [0007]
    [0008] The object of the present invention lies in a continuous manufacturing machine of prestressed concrete plates that is distinguished by comprising means for applying a label in the form of lateral toothing to the plates, designed to improve its behavior on site, for which , said machine is equipped with a mechanism that, manually controlled, makes said marking automatically. The object of the present invention is also the component of a machine for the continuous production of prestressed concrete plates intended to apply a label in the form of lateral toothing to the plates.
    [0009]
    [0010] FIELD OF APPLICATION OF THE INVENTION
    [0011]
    [0012] The field of application of the present invention is part of the construction sector, focusing particularly on the field of industry dedicated to the manufacture of machinery for the manufacture of construction elements, in particular pre-stressed concrete plates.
    [0013]
    [0014] BACKGROUND OF THE INVENTION
    [0015]
    [0016] It is known that the inclusion of a lateral marking of the concrete plates brings advantages to their behavior on site. Thus, the plates with said marking on the sides adjacent to a contiguous plate are more bound to each other in the seismic zones, which is why they are known as anti-seismic plates. But, in addition, for a given friction value between them, the lateral marking of the plates allows to reduce the amount of concrete that is poured to complete the floor or structure of concrete, which supposes, therefore, a saving of material and of costs.
    [0017]
    [0018] In any case, it is not known the existence of any machine or similar invention that allows practically performing said marking on the plates at the same moment of their manufacture, this being the objective of the present invention.
    [0019]
    [0020] It is also an object of the invention to avoid the deformation of the concrete, still wet, which causes said lateral marking mechanism on the adjacent alveolar hollows, which prevents said marking from being very deep.
    [0021]
    [0022] Thus, as a reference to the current state of the art, at least on the part of the applicant, the existence of any other machine or invention that presents technical, structural and constitutive characteristics similar to those presented here is not known.
    [0023]
    [0024] EXPLANATION OF THE INVENTION
    [0025]
    [0026] The continuous manufacturing machine of prestressed concrete plates that the invention proposes is configured, therefore, as a novelty within its field of application, since according to its implementation the indicated objectives are satisfactorily achieved, the details being characteristic that make possible and that distinguish conveniently collected in the final claims that accompany the present description.
    [0027]
    [0028] Specifically, what the invention proposes, as indicated above, is a machine for the continuous production of prestressed concrete plates, using an extrusion manufacturing machine by means of the gravity of a concrete column, although this does not imply a limitation , which is distinguished by comprising means for applying a marking in the form of teeth on both sides to the plates during the process of forming them, which, with a thickness of at least 5 millimeters, is eminently intended to improve their behavior on site, for example in the face of seismic movements to minimize the relative movements between contiguous plates.
    [0029]
    [0030] For this, and more specifically, the machine of the invention, in addition to the known elements for forming the plates, such as a supporting structure, a concrete feeder and lateral guides to the area of expulsion that determine its size and shape, and may include elements to provide alveolar gaps, is equipped with a mechanism that prints the teeth to the sides of the plate at the time of its formation .
    [0031]
    [0032] Said mechanism, preferably of hydraulic drive, preferably comprises a piece of marking mold, with the chosen configuration, associated with the structure thereof in an appropriate area of the ejection zone, in such a way that, when convenient, it moves to press and mark the corresponding toothed relief on the side surface of fresh concrete.
    [0033]
    [0034] To do this, the actuation of this mechanism synchronized with the automatic advance of the machine, is carried out by means of a selector in the control panel. If the selector is in the rest position, the mechanism does not act.
    [0035]
    [0036] If the automatic control mechanism is provided, said mechanism is connected to a programmable automaton to calculate at what moment the repeated mechanism must be activated.
    [0037]
    [0038] As indicated in the previous section, the problem of the formation of these plates with said longitudinal alveolar hollows that cover its entire width and the side markings with the wet concrete, is given by the limitation of the depth of the marking by the deformation that the material, which is still soft, suffers in the gaps adjacent to the sides when pressure is applied on said sides to conform the marking with the marker punch, since the position of said punch in the machine is subsequent to that of the tuning molds tubular that make up the alveolar gaps and the pressure is applied repetitively when the plate emerges when these no longer occupy said gaps.
    [0039]
    [0040] Thus, to solve said problem and to be able to improve the result and depth of the mark of the marker punch avoiding deformations, what distinguishes the machine of the present invention is the existence, in one or both tubular tuning molds of the ends of the assembly of the same ones that determine the formation of the alveolar hollows adjacent to the sides of the concrete plate, according to whether the machine has a marker punch in one or both sides of the outlet mouth, of tubular extensions of smaller dimension than those of the tuning molds that extend until facing the position of the marker punch, that is, until the zone where the deformation of the fresh concrete takes place by means of the punch marker.
    [0041]
    [0042] In this way, said extension along with the inner side of the lateral guide in the exit mouth of the structure of the machine maintain the shape of the newly produced plate, with the peculiarity that the smaller size of this prolongation with respect to the alveolus or cavity produced by the tubular tuner mold allows to accommodate the displaced concrete when performing the punching.
    [0043]
    [0044] The invention also relates to a component applicable to a machine for the continuous production of pre-stressed concrete plates. Said component comprises a mechanism that prints a toothing on the sides of the plate at the time of its conformation and also preferably comprises at one or both end elements for the formation of alveolar voids (8), that is, those located at the ends of all of them, according to whether the machine has marking molds on one or both sides of the outlet mouth, incorporates tubular extensions that emerge from the front of said external elements, which have smaller dimension than them and which they extend frontally, being laterally facing the position of the marking mold on each side. In an even more preferred embodiment, the tubular extensions emerging from the front of the external elements have a smaller dimension than they in their height.
    [0045]
    [0046] The described machine of continuous manufacture of prestressed concrete plates consists, therefore, in an innovative structure of characteristics unknown until now for the purpose for which it is intended, reasons that together with its practical utility, provide it with sufficient grounds to obtain the privilege of exclusivity that is requested.
    [0047]
    [0048] DESCRIPTION OF THE DRAWINGS

    [0061]
    [0062] PREFERRED EMBODIMENT OF THE INVENTION
    [0063]
    [0064] In view of the aforementioned figures, and in accordance with the numbering adopted in them, a non-limiting example of the continuous manufacturing machine of pre-stressed concrete plates of the invention can be appreciated, which comprises the parts and elements that are indicated and described in detail below.
    [0065]
    [0066] Thus, as can be seen in said figures, the machine (1) in question is a machine for the continuous production of prestressed concrete plates (2), comprising, essentially and in a known manner, a supporting structure (3), a feeder (4) of concrete and guides (5, 5 ') arranged on both sides of the outlet mouth (6), optionally provided with elements (7, 7') for the formation of the alveolar voids (8), for the one that continually emerges from the concrete, still fresh but already forming the plates (2), as the machine moves (1), it is distinguished by counting, in addition, with integrated means in it to apply a toothed mark (9) in one or on both sides (2a) of the plates (2) emerging through said outlet (6) during the process of forming them.
    [0067]
    [0068] Preferably, the toothed mark (9) that prints the machine to the plates (2) has a thickness of at least 5 millimeters, being eminently intended to prevent the action of lateral forces in the longitudinal direction of the plates.
    [0069]
    [0070] In any case, said means for applying the toothed mark (9) to the sides (2a) of the pre-stressed plates (2) of concrete that continuously form the machine (1) are determined by the existence of a mechanism therein ( 10), preferably of hydraulic or pneumatic drive, which moves pieces or molds (11) of marking, with the chosen configuration, pressing them against the fresh concrete on the sides (2a) of the plates (2) in a calculated way each time agree, as the material emerges from the machine.
    [0071]
    [0072] For this, preferably, said marking molds (11) are arranged coupled to the respective ends of respective lateral arms (12) which, provided for this purpose on both sides of the supporting structure (3) of the machine (1), are coupled, in turn, to separate movable supports (13), with which they move moved by them in opposite directions, approaching and moving away from the sides of the outlet (6), to press on the sides of the plate (2) and go printing the teeth (9).
    [0073]
    [0074] For this, preferably, as shown in the detail of figure 2, the described mold (11), on each side of the machine (1), is fitted between the upper (5) and lower (5 ') guides on both sides of the outlet (6) where the fresh concrete that forms the plates (2) emerges ).
    [0075]
    [0076] Likewise, in said figure 2 it is observed that, in the preferred embodiment, the mold (11) has a marking surface (11a) of rectangular configuration.
    [0077]
    [0078] It should also be noted that, although the control of the operation of the described mechanism (10) is manual by means of a selector, its operation is carried out in an automatic way, for which purpose, the means for actuating the mechanism (10), preferably constituted by two hydraulic cylinders (14), are connected to a programmable automaton (not shown) that calculates at what moment it must trigger its movement.
    [0079]
    [0080] Preferably, the machine (1) is distinguished by the fact that, in one or both end elements (7 ') for the formation of the alveolar hollows (8), that is, those located at the ends of the assembly thereof that, depending on whether the machine has a marking mold (11) on one or both sides of the outlet mouth (6), incorporates tubular extensions (15) emerging from the front of said external elements (7 ') , which have smaller dimension than them, preferably in regard to their height, and which, in any case, extend frontally until they are laterally facing the position of the marking punch (11) on each side.
    [0081]
    [0082] In the detail of figure 5 it can be seen how the said smaller dimension of the tubular extension (15) that emerges from the front part of each end element (7 ') defines a space, above and below it, so that the material that is pushed by the action of the marking mold (11) when penetrating the side (2a) of the plate (2) moves superiorly and inferiorly to the adjacent alveolar hollow (8), represented by arrows in said figure 3, allowing the serrated marking (9) to be deeper without deforming or weakening the partition of said side (2a) of the plate (2).
    [0083]
    [0084] With this, and thanks to the existence of said extensions (15) of the molds (7 ') of the ends that define the alveolar hollows (8), the toothed mark (9) that print the machine (1) on the sides (2a) of the plates (2) has a thickness that can easily exceed 5 millimeters, and optimize its function to avoid the action of lateral forces in the longitudinal direction of the plates, by example before seismic movements.
    [0085]
    [0086] Having sufficiently described the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to extend its explanation so that any expert in the field understands its scope and the advantages derived therefrom, stating that, within its essentiality, it may be carried out in other modes of realization that differ in detail from that indicated by way of example, and to which it will also achieve the protection that is sought provided that it is not altered, changes or modifies its fundamental principle .
