    [0001] CONNECTOR FOR FORMWORK SYSTEMS AND FORMWORK SYSTEM
    [0002]
    [0003] Field of the Invention
    [0004] The present invention refers to a connector for formwork systems, specially designed to work with various types of formwork panels, expanding their applicability, functionality, manageability and performance, as well as to allow the compatibility of said panels with each other in multiple applications.
    [0005]
    [0006] The present invention also relates to a formwork system for the construction of concrete structures in general and, especially, for the construction of walls, columns and pillars, which employs said connector.
    [0007]
    [0008] Background of the Invention
    [0009] Various types of formwork panels are currently known for formwork systems, especially modular. These panels are usually formed by a phenolic plywood lining that is structurally reinforced by a galvanized steel frame or structural frame between which a plurality of horizontally arranged metal profiles are arranged.
    [0010]
    [0011] The different measurements of the panels, the type of material, the thickness of the plywood, the number of profiles, among other aspects, are what determine the admissible working pressure of the panel during the setting of the concrete. In turn, the constructive configuration of the same (technical characteristics of the frame / frame and of the profiles, their arrangement, connection methods, etc.) determines their use and / or the applications for which they are intended. .
    [0012]
    [0013] In other words, each type of formwork panel is usually designed for application in the construction of concrete formwork structures, not being compatible with other formwork solutions, nor being able to work together with other different formwork panels.
    [0014] For example, one of the most widely used formwork panels in wall construction is known as a “standard panel”. These types of panels are assembled side by side forming two parallel rows, facing their phenolic plywood linings to form the two concrete faces of the wall. The union between panels of the same row is made through the use of staples configured to join the structural frames of adjacent panels.
    [0015]
    [0016] When the wall forms a corner, for example due to a protrusion or a change in the direction of the wall, the union between the panels forming the corner is usually carried out as follows. First, the panels next to the corner are selected according to their dimensions (usually by their width), so that they fit the dimensions of that corner. Once these panels are attached to the panels that precede them, also through the use of staples, there end up being two panels arranged at an angle, the widths of which are normally less than those of the panels that precede them. To join the vertical edges of the frames of the panels that form the corner, the use of so-called connection columns, angles or corners, which can be interior or exterior, depending on the side of the wall on which they are assembled, is usually used. Said connecting columns are in turn attached to the frames of the panels that form the corner, again through the use of staples. This type of solution requires having panels of different sizes, external connection elements (angles), also of different sizes, and with a greater number of clips (higher density of clips per square meter). All this supposes a greater time of assembly of the formwork, as well as the need to have a greater stock of materials of different dimensions.
    [0017]
    [0018] WO2016 / 139513A1 shows another type of formwork panel specially designed for use in formwork systems for the construction of pillars or columns, which is called "universal modular panel". This panel does not require the use of connection angles for the formation of pillars or columns, and allows the use of panels of the same size in their formation. Specifically, each of the joints between two universal panels is carried out by using a threaded insertion bar, or universal stud, which is inserted from the plywood side (rear, or non-visible part of the panel one once assembled) of one panel, passing through the frame of another panel with which it connects, until it protrudes from the side of the profiles (front, or visible part of the panel once assembled) of the first panel. The closure is completed by inserting a plate in said stud from the external face of the panel profiles, which works in collaboration with a nut at the rear.
    [0019]
    [0020] Despite the mentioned advantages, this formwork system has several drawbacks. First, the union between universal panels has to start from the rear of the panel, leaving little room for the insertion of the stud and for its manipulation until it protrudes from the front. Therefore, hindering the execution works to carry out said union. Secondly, it requires greater accessibility to the rear of the panel, which prevents its application in other types of concrete structures, such as retaining walls, the rear of which is less accessible. Finally, these universal panels are incompatible with other types of formwork panels, such as, for example, with the standard panels discussed above. That is, it does not allow the assembly and / or union of different panels from each other.
    [0021]
    [0022] The present invention solves the problems previously exposed, by means of a connector whose configuration allows to join panels of different types, for example, standard panels with universal panels, taking advantage of each other, in addition to increasing their applicability, functionality, manageability and benefits, both individually (in panels of the same type) and collectively (combining panels of different types). The present invention also solves the problems previously exposed, by means of a formwork system that uses said connector for various constructive solutions.

    [0161] Figure 29 represents a partial section in detail, according to a vertical section, showing the union of the first two panels facing and inclined to each other.
    [0162] Detailed description of the invention
    [0163] Figures 1-4 represent various views of the connector (1) for formwork systems of the present invention. As can be seen, said connector (1) comprises: - a connecting element (2) configured to be inserted into a support profile (41, 51) of a formwork panel (4, 5), provided with a receiving hole ( 21) configured to receive an insertion bar (6); and
    [0164] - a fastening element (3) attachable to the connection element (2), configured to rest on the support profile (41, 51) and hold the connection element (2) on said support profile (41.51) .
    [0165]
    [0166] The receiving hole (21) has an internal threading (210) configured to guide the threading through the connecting element (2) of an insert bar (6) with external threading (61).
    [0167]
    [0168] As can be seen in Figures 5-7, the connecting element (2) comprises a longitudinal axis (2Y) and a transverse axis (2X), the receiving hole (21) being arranged in the direction of the transverse axis (2X) . The connecting element (2) comprises two insertion sides (22) each delimited by an upper face (24) and a lower face (25). Said insertion sides (22) are configured to slide along an inner rail (421,521) of a structural frame (42, 52) of the support panel (4, 5), Figures 18, 20 and 25.
    [0169]
    [0170] To favor the introduction of the connecting element (2) in the support profile (41,51), each insertion side (22) is formed by:
    [0171] - a flat inlet face (221); and
    [0172] - two flat and opposite guide faces (222) that diverge from the inlet face (221), each forming an obtuse angle with respect to said inlet face (221).
    [0173]
    [0174] In this way, the operator can fit the insertion side (22) of the connecting element (2) in the inner rail (421, 521) of the structural frame (42, 52), which has a complementary contour to that of the insertion (22) in order to facilitate its sliding along said inner rail (421,521), Figures 18, 20 and 25.
    [0175] The connecting element (2) comprises two central sides (23), flat and opposite each other, arranged between the insertion sides (22) contiguously thereto. Said central sides (23) are enabled to allow the attachment of the connecting element (2) by the operator during its introduction into the support profile (41,51).
    [0176]
    [0177] According to the present example of preferred embodiment, the connecting element (2) comprises an octagonal prismatic shape, especially suitable to facilitate both its insertion in the inner rail (421, 521) of the structural frame (42, 52), as well as its introduction in the support profile (41,51) of the formwork panel (4, 5). Furthermore, said geometry is also highly robust and compact, capable of withstanding working pressures during concreting and setting of the concrete, as well as possible impacts during its use, favoring the durability and reuse of the connector (1).
    [0178]
    [0179] Likewise, the connecting element (2) has a symmetrical configuration that further facilitates its use, allowing its introduction into the support profile (41,51) both on its lower face (25) and on its upper face (24), as well as its insertion in the inner rail (421,521) both on the right insertion side (22) and on the left insertion side (22).
    [0180]
    [0181] The connecting element (2) comprises coupling means (26) configured to allow mounting and dismounting of the clamping element (3) on the connecting element (2). According to the present preferred embodiment, the coupling means (26) comprise a pair of slits (26a) opposite each other that start on an upper face (24) and / or on a lower face (25) of the joint (2), and each of which extends into said joint element (2) until reaching a retention hole (26b) configured to receive one end of the fastening element (3) and retain it.
    [0182]
    [0183] As can be seen in Figures 8-10, the fastening element (3) comprises: - two support portions (31); and
    [0184] - an insertion portion (32) of elastic character that joins the two support portions (31).
    [0185] Said support portions (31) are configured to approach or separate from each other due to the elasticity of the insertion portion (32), like a spring.
    [0186]
    [0187] Each support portion (31) is made up of:
    [0188] - a coupling end (311) configured to couple to the connecting element (2), in this case, in a retention hole (26b), Figure 4;
    [0189] - a first support section (312) extending from the coupling end (311); - an intermediate section (313) extending from the first support section (312); and - a second support section (314) extending from the intermediate section (313) substantially perpendicular to the first support section (312).
    [0190]
    [0191] In turn, the insertion portion (32) is formed by:
    [0192] - a first protruding section (321) configured to hook onto the support profile (41, 51) of the formwork panel (4, 5), Figure 25, which extends from the second support section (314) of one of the portions of support (31);
    [0193] - a first straight section (322) extending from the first protruding section (321);
    [0194] - a curved section (323) extending from the first straight section (322), configured to embrace the insertion bar (6) below the receiving hole (21) when the first support sections (312) of the support portions (31) rest on the support profile (41,51), Figure 25;
    [0195] - a second straight section (324) extending from the curved section (323); and
    [0196] - a second protruding section (325), opposite to the first protruding section (321), configured to hook onto the support profile (41, 51) of the formwork panel (4, 5), Figure 25, which extends from the second straight section (324) and that connects with the second support section (314) of the other support portion (31).
    [0197]
    [0198] The fastening element (3) is made up of a flexible fastening clip or wire, made of metallic material.
    [0199]
    [0200] The fastening element (3) is configured to allow a first support position (3p1), Figure 20, and a second support position (3p2), Figure 25, on the support profile (41,51) of the panel of formwork (4, 5).
    [0201]
    [0202] Figures 11 and 12 represent respectively a front view and a profile view of a first formwork panel (4) of the "standard panel" type, according to the present invention.
    [0203]
    [0204] As can be seen, said first formwork panel (4) presents:
    [0205] - a plurality of support profiles (41), in this case two, each formed by a support bar (411) having at least one first end (412) from which a plate (413) with arms extends connecting (414); and
    [0206] - a first structural frame (42) to which the connecting arms (414) connect.
    [0207]
    [0208] The greater the number of first support profiles (41), the higher the admissible working pressure of the first formwork panel (4) is during the setting of the concrete.
    [0209]
    [0210] The first formwork panel (4) comprises a plurality of first lateral holes (422) that cross the first structural frame (42) being located in correspondence with the plates (413). That is to say, located at the same height as the first support profiles (41). Additionally, the first formwork panel (4) comprises at least a first auxiliary hole (423) that passes through the structural frame (422).
    [0211]
    [0212] Figures 13 and 14 represent respectively a front view and a profile view of a second formwork panel (5) of the "universal panel" type, according to the present invention.
    [0213]
    [0214] As can be seen, said second formwork panel (5) presents:
    [0215] - a plurality of second support profiles (51), in this case two, each formed by two support wings (511) having at least one second end (512); and a plurality of connecting holes (514) distributed along said support profile (51) between the support wings (511), which cross the second formwork panel (5) perpendicularly; and
    [0216] - a second structural frame (52) that connects with the second end (512) of the support wing (511).
    [0217]
    [0218] The greater the number of second support profiles (51), the greater the admissible working pressure of the second formwork panel (5) during the setting of the concrete.
    [0219]
    [0220] The second formwork panel (5) comprises a plurality of second lateral holes (522) that cross the second structural frame (52) being located between the support wings (511) of each second profile (51). That is, located at the same height as the second support profiles (51).
    [0221]
    [0222] Both in the first formwork panel (4) and in the second formwork panel (5), the distribution of holes (422, 423, 522) in the structural frames (42, 52) allows to identify the type of panel (4, 5), even when they are stacked on top of each other, hiding their support profiles (41,51).
    [0223]
    [0224] In turn, said support profiles (41, 51) also have a symmetrical configuration, allowing the assembly of the formwork panels (4, 5) so that they rest on a base of the structural frame (41.52) parallel to the support profiles (41,51), or inverted 180 ° with respect to it to rest on another opposite base, interacting in the same way with the connector (1). That is, the operator does not have to worry about positioning the panels (4, 5) in one position or another, but simply putting them upright.
    [0225]
    [0226] Figure 15 represents a front view of a set of first panels (4) and second panels (5) joined laterally in the same direction. Specifically, said set has a first formwork panel (4) arranged between two second formwork panels (5).
    [0227]
    [0228] The first formwork panel (4) and the second formwork panel (5) located to the left of Figure 15 correspond, respectively, to the first formwork panel (4) and to the second formwork panel (5) of Figures 11 and 13. As can be seen, the first support profiles (41) and the second support profiles (51) are arranged at the same height, allowing their lateral connection along the same direction (for example, along along one wall of the wall to be built).
    [0229]
    [0230] The second formwork panel (5) located to the right of Figure 15, corresponds to a second formwork panel (5) that has a greater number of second profiles support (51), in this case four, as well as a height distribution different from that of the second formwork panel (5) located on the left. Despite this, the first formwork panel (4) and the second formwork panel (5) located on the right can also be joined laterally, thanks to the first auxiliary holes (423) of the first formwork panel (4). This further increases the compatibility between the different panels (4, 5) and, consequently, their versatility in a greater number of construction solutions.
    [0231]
    [0232] Figures 16-21 represent a first example of constructive application of the formwork system (10) of the present invention.
    [0233]
    [0234] As can be seen in Figures 16 and 17, said formwork system (10) comprises:
    [0235] - a first formwork panel (4) provided with at least a first support profile (41) and a first structural frame (42); and
    [0236] - a second formwork panel (5) provided with at least a second support profile (51) and a second structural frame (42).
    [0237]
    [0238] Where said first formwork panel (4) and said second formwork panel (5) are perpendicularly joined by at least one connector (1) according to the present invention, to form the outer corner of a concrete wall.
    [0239]
    [0240] The inner corner of the wall is formed by joining two first formwork panels (4) through a connection column (A), also known as an interior corner or angle.
    [0241]
    [0242] As seen in Figures 18 and 19, the first formwork panel (4) has: - at least a first support profile (41) formed by a support bar (411) that has a first end (412) of which a plate (413) is prolonged, where said plate (413) has two connecting arms (414) between which an inlet (415) is defined; and
    [0243] - a first structural frame (42) to which the two connection arms (414) connect.
    [0244]
    [0245] In turn, the first structural framework (42) includes:
    [0246] - a first inner rail (421) configured to partially house the connecting element (2), which forms an insertion hole (43) with the recess (415) to allow the introduction of the connecting element (2) in the first profile support (41) and the support of the clamping element (3) on the plate (413); and
    [0247] - a first lateral hole (422) that passes through the first structural frame (42) through the inner rail (421), and that is configured to face the receiving hole (21) of the connecting element (2), allowing passage of an insertion bar (6) through both holes (21,422).
    [0248]
    [0249] The receiving hole (21) has an internal threading (210) configured to guide the threading through the connecting element (2) of an insert bar (6) with external threading (61). The insertion bar (6) also includes a plate (62) configured to press against the second support profile (51), and a wing nut or butterfly (63) that allows the operator to fix the insertion bar (6) in addition to tightening the plate (62) against the second support profile (51).
    [0250]
    [0251] The second formwork panel (5) presents:
    [0252] - at least a second support profile (51) formed by two support wings (511); and a plurality of connecting holes (514) distributed between the support wings (511) along said support profile (51) that cross the second formwork panel (5) perpendicularly; and
    [0253] - a second structural framework (52).
    [0254]
    [0255] As shown in Figure 20, once the connecting element (2) has been inserted into the first support profile (41), the fastening element (3) rests on said first support profile (41), holding the connecting element (2) until the insertion bar (6) is inserted.
    [0256]
    [0257] In this case, the fastening element (3) adopts a first support position (3 p 1), resting on the plate (413) through the insertion portion (32) and, specifically, by means of its straight sections ( 322, 324) and its curved section (323).
    [0258]
    [0259] As seen in Figure 21, the connecting holes (514) of the second support profile (51) allow the insertion of the insertion bar (6) through the second panel formwork (5), until its end is housed inside the plate (413) of the first support profile (41) after passing through the connection element (2).
    [0260]
    [0261] According to this first application example, the joining of the panels (4, 5) that form the outer corner of the wall is carried out as follows. The first formwork panel (4) is arranged so that one of its vertical ends coincides with the edge of the corner of the wall to be built. The second formwork panel (5) is arranged perpendicularly to the first formwork panel (5), matching a plurality of joint holes (514) vertically aligned with a certain number of first lateral holes (422). Specifically, the number of connection holes (514) that faces the first lateral holes (422) coincides with the number of first support profiles (41). The second formwork panel (5) can protrude frontally to a greater or lesser extent, depending on its dimensions (width) and the position occupied by the other first formwork panel (4) to which it is attached laterally in the direction of the wall to build. In any case, the operator can use second formwork panels (5) of different dimensions to build the formwork that forms the corner.
    [0262]
    [0263] Subsequently, the connector (1) is adapted to the type of application, in this case coupling the fastening element (3) to the connecting element (2) so that it adopts the first support position (3 p 1) shown in Figure 20 Once the connector (1) has been adapted, the connecting element (2) is inserted into the first support profile (41) until the clamping element (3) rests on it, facing the receiving hole (21 ) to the first side hole (422). The operator can then release the connector (1), and easily proceed to insert the insertion bar (6) from the front of the formwork. The insertion bar (6) first passes through the second formwork panel (5) through one of the connecting holes (514). It then passes through the first structural frame (42) through the first lateral hole (422) that is opposite said connecting hole (514), until its end reaches the receiving hole (21). Finally it goes through the connecting element (2) by threading the insertion bar (6) through it. The entire process described above can be carried out by one person.
    [0264]
    [0265] Figures 22-25 represent a second example of constructive application of the Formwork system (10) of the present invention.
    [0266]
    [0267] As can be seen in Figures 22 and 23, said formwork system (10) comprises:
    [0268] - two second formwork panels (5) each provided with at least a second support profile (51) and a second structural frame (52).
    [0269]
    [0270] Where said second formwork panels (5) are perpendicularly joined by at least one connector (1) according to the present invention to form the outer corner of a concrete wall.
    [0271]
    [0272] The inner corner of said wall is formed by joining two second formwork panels (5) through a connecting column (A), also known as an interior corner or angle.
    [0273]
    [0274] As seen in Figures 24 and 25, each second formwork panel (5) has: - at least a second support profile (51) formed by two support wings (511), which has a second end (512) with at least one insertion slot (513) configured to allow a partial insertion of the clamping element (3) and its support on the support wing (511); and a plurality of connecting holes (514) distributed between the support wings (511) along said support profile (51) that cross the second formwork panel (5) perpendicularly; and
    [0275] - a second structural frame (52) that connects with the second end (512) of the support wing (511).
    [0276]
    [0277] In turn, the second structural framework (52) includes:
    [0278] - a second inner rail (521) configured to partially house the connecting element (2); and
    [0279] - a second lateral hole (522) that crosses the second structural frame (52), and which is configured to face the receiving hole (21) of the connecting element (2), allowing the passage of an insertion bar (6 ) through both holes (21,522).
    [0280]
    [0281] In Figure 25, the second lateral hole (522) facing the connecting element (2) the connecting element (2) is precisely covered by said
    [0282]
    [0283] The receiving hole (21) has an internal threading (210) configured to guide the threading through the connecting element (2) of an insert bar (6) with external threading (61). The insertion bar (6) also includes a plate (62) configured to press against the second support profile (51), and a wing nut or butterfly (63) that allows the operator to fix the insertion bar (6) in addition to tightening the plate (62) against the second support profile (51).
    [0284]
    [0285] As can also be seen in Figure 25, once the connecting element (2) has been inserted into the second support profile (51), the fastening element (3) rests on said second support profile (51), holding the connecting element (2) until the insertion bar (6) is inserted.
    [0286]
    [0287] In this case, the fastening element (3) adopts a second support position (3p2), resting on the support wing (511) through the support portion (31) and, specifically, through its support sections. (312).
    [0288]
    [0289] In turn, the connection holes (514) of the second support profile (51) allow the insertion of the insertion bar (6) through the second formwork panel (5), until its end is lodged between the wings of support (511) of the second support profile (51) of the other second formwork panel (5) after passing through the connection element (2).
    [0290]
    [0291] According to this second application example, the panels (5) that form the outer corner of the wall are joined in the following way. One of the second formwork panels (5) is arranged so that one of its vertical ends coincides with the edge of the corner of the wall to be built. The other second formwork panel (5) is arranged perpendicular to the aforementioned second formwork panel (5), matching a plurality of vertically aligned connection holes (514) with a certain number of second lateral holes (522). Specifically, the number of connection holes (514) that faces the second lateral holes (522) coincides with the number of second support profiles (51). The second formwork panel (5) can protrude frontally in greater or lesser measure, depending on its dimensions (width) and the position of the other second formwork panel (5) to which it joins laterally in the direction of the wall to be built. In any case, the operator can use second formwork panels (5) of different dimensions to build the formwork that forms the corner.
    [0292]
    [0293] Subsequently, the connector (1) is adapted to the type of application, in this case decoupling the fastening element (3) from the connecting element (2) so that it adopts the second support position (3 p 2) shown in Figure 25 Once the connector (1) has been adapted, the connecting element (2) is inserted into the second support profile (51), specifically, inserting it frontally between the two support wings (511) in an upright position and partially housing it in the second inner rail (521), the receiving hole (21) being opposite the second lateral hole (522). Then the insertion portion (32) of the fastening element (3) is introduced through the insertion groove (513) of the second support profile (51), until the fastening element (3) rests on it. The insertion portion (32) is then faced with the receiving hole (21). The protruding sections (321,325) laterally press against the inner contour of the insertion groove (513), due to the elasticity of the fastening element (3), to keep it fixed to the second support profile (51). The operator can then release the connector (1), and easily proceed to insert the insertion bar (6) from the front of the formwork. The insertion bar (6) first passes through the second formwork panel (5) through one of the connecting holes (514). It then passes through the second structural frame (52) of the other second formwork panel (5) through the second lateral hole (522) that is opposite said connection hole (514), until its end reaches the receiving hole (21) . Finally, it crosses the union element (2) by threading the insertion bar (6) through it, being embraced inferiorly by the curved section (323) of the fastening element (3). The entire process described above can be carried out by one person.
    [0294]
    [0295] Figures 26-28 represent a third example of constructive application of the formwork system (10) of the present invention.
    [0296]
    [0297] As can be seen, said formwork system (10) comprises:
    [0298] - a plurality of first formwork panels (4) each provided with at least a first support profile (41) and a first structural frame (42).
    [0299]
    [0300] The row of first adjoining formwork panels (4) forms a rear part of the retaining wall, considered the least accessible. These first formwork panels (4) are joined laterally by staples (9). The first formwork panel (4) facing said row of first formwork panels (4) forms an anterior part of the retaining wall, considered the most accessible. The first two facing formwork panels (4) are joined by at least one connector (1) according to the present invention to form a retaining wall. Between both facing panels (4) the protection tube (8) that protects the insertion bar (6) through the wall can be seen.
    [0301]
    [0302] The first formwork panel (4) comprises a containment hole (416) arranged inside the plate (413) through the phenolic plywood lining, Figure 18.
    [0303]
    [0304] The system (10) additionally comprises an introduction stop (7) that has: - a pressure plate (71) configured to press against a first formwork panel (4), which has a pressure hole (75) configured to receive an insertion bar (6);
    [0305] - two support walls (72) that extend perpendicularly from the pressure plate (71), the pressure hole (75) being arranged between them; and
    [0306] - a stop wall (73) that joins the support walls (72), said walls (72, 73) forming a substantially "U" profile, and which is configured to stop the advancement of the insertion bar (6) .
    [0307]
    [0308] Where at least one of the support walls (72) has an introduction hole (74) configured to allow the introduction of the connecting element (2), the receiving hole (21) of the connecting element (2) facing the hole pressure (75), allowing the passage of the insertion bar (6) through both holes (21,75), and where the fastening element (3) is supported on said support wall (72) to hold subject the connecting element (2) in said insertion stop (7).
    [0309]
    [0310] In turn, the stop wall (73) has an indicator hole (77) facing the pressure hole (75), which serves to notify the operator that the insertion bar (6) has passed through completely the wall, since this insertion operation is performed from the front of the wall. The indicator hole (77) has a smaller diameter than that of the insertion bar (6), so that the operator perceives a sudden tactile change during the introduction of the insertion bar (6), knowing at that time that the insertion bar (6) has crossed the wall.
    [0311]
    [0312] The introduction stop (7) comprises gripping legs (76) that project perpendicularly from the pressure plate (71) to be fixed to the first structural frame (42) of the first formwork panel (4).
    [0313]
    [0314] According to this third application example, the panels (4) that form the retaining wall are joined in the following way. First, the connector (1) is adapted to the type of application, in this case coupling the clamping element (3) to the connecting element (2) so that it adopts the first support position (3 p 1) shown in Figure 27. The connecting element (2) is inserted into the first support profile (41) through the insertion hole (74) of the insertion stop (7). The fastening element (3) is therefore supported on the first support profile (41), holding the connecting element (2) attached to said first support profile (41). The operator can then release the connector (1), and easily proceed to insert the insertion bar (6) from the front of the formwork, the most accessible. The insertion bar (6) goes through the first formwork panel (4) arranged on the front face of the wall, through the containment hole (416), to be subsequently inserted into the protection tube (8). Then it passes through the first formwork panel (4) arranged on the dorsal face of the facing wall, through its corresponding containment hole (416). It then passes through the pressure stop (71) through the pressure hole (75), until its end reaches the receiving hole (21). Finally it goes through the connecting element (2) by threading the insertion bar (6) through it. The entire process described above can be carried out by one person.
    [0315]
    [0316] Figure 29 represents a particular application of the first formwork panels (4) when they are joined at the front in an inclined way.
    [0317]
    [0318] As you can see, each deck (413) has:
    [0319] - a posterior narrowing (413a) substantially U-shaped in section constant cross; and
    [0320] - an anterior widening (413b) extending from the posterior narrowing (413a) with an increasing cross section.
    [0321]
    [0322] This funnel shape of the plate (413) allows a greater inclination of the first formwork panels (4). Also, the anterior widening (413b) facilitates the introduction of the insertion bar (6).
