    FORMING HOLDING DEVICE FOR BUILDING ELEMENT. CONSTRUCTION ELEMENT PROVIDED WITH SAID DEVICE AND FORMWORK METHOD USING THE SAME
    Technical area :
    The present invention relates to a formwork holding device for holding at least one shuttering panel arranged to close at least partially a recess provided in a construction element, said recess being between two opposite faces of said building element each delimited by a slice, said shuttering panel being at least partially supported on said slices.
    The present invention also relates to a construction element and a formwork method.
    Prior art:
    An integrated form wall is usually in the form of two walls commonly called skins, substantially parallel and kept at a distance from each other by connecting armatures. An integrated formwork wall is a prefabricated factory building element that is intended to be routed to a construction site. The distance between the two skins, is intended to receive a material that can be cast in place on site, such as concrete. After hardening, this filling material forms the core of the integrated form wall. Both walls play the role of formwork.
    Most often to form a construction, a plurality of integral form walls are used which are adjacent two by two by their respective lateral ends.
    To form angles, it is common for the walls of adjacent integral form walls to be offset relative to each other in parallel planes. In both cases, the continuous formwork of the core is ensured. However, depending on the type of construction, it is also common for one of the lateral ends of an integrated formwork wall to be left free, ie no other adjacent structural element is present. in the continuity of this lateral end. It is therefore necessary to form a form stop at the lateral end before casting the core.
    Most of the time to form such a shuttering stop, a plank, usually made of wood, is used which is arranged along the lateral end of the integrated shuttering wall so as to close the lateral end. In general, the formwork shutoff board is fixed to the formwork wall integrated on site by fixing means. The formwork board is often attached to the integrated formwork wall by means of pegs distributed along the lateral ends of the walls of the integrated formwork wall. This solution has the disadvantage of requiring at least two operators to hold on the one hand the formwork shutter board and secondly to drill and dice the slices of the walls of the integrated formwork wall. In addition, after formwork, it is necessary to remove the dowels and re-fill the holes. This results in a long labor time. In addition, slab piercing and formwork stripping by peel removal can adversely affect the integrity of the wall by damaging the lateral ends of the walls having a small thickness compared to the diameter of the pegs. The formwork shutter board is also often damaged and is therefore difficult to re-use. In addition, this system only allows to form a side end of wall integrated formwork right and not a lateral end at an angle. It is also known to hold the shuttering shuttering board by means of clamps put in place through pre-drilled holes in the shuttering board and surrounding an internal reinforcement of the core passing right through the wall. This solution has the disadvantage of being relatively complex to set up, since a perfect alignment between each hole and the corresponding reinforcement is necessary. The formwork is also tedious since it is necessary to cut the clamps protruding from the lateral end of the integrated formwork wall and to cover the holes.
    Another known possibility of the prior art is to fix the formwork shutter board to the integrated formwork wall during its manufacture in the factory. In this case, the shuttering board is equipped with anchoring means, nail type, which are embedded in the lateral ends of the walls during casting thereof. This solution is not optimal since it is not totally secure. Indeed, cut risks are incurred by the operators when the anchoring means are apparent during casting or stripping. Rust spots may also appear at the lateral ends of the walls after stripping. In addition, this system only allows to form a lateral end of the right wall and not a lateral end at an angle. The integrated formwork wall obtained also has the disadvantage of not being standard.
    Finally, it is also known to prefabricate at the factory an integrated formwork wall whose side end is closed beforehand by a concrete allowance. This solution has the disadvantage of having to substantially modify the manufacturing molds integrated formwork walls and increase manufacturing costs.

Illustrations of the invention and the best way of producing it:
    With reference to FIGS. 1 to 5, the present invention relates to a formwork holding device 1 which makes it possible to maintain a formwork panel 3 on a construction element 2 and which is arranged to close at least partially a recess 21 provided in FIG. construction element 2. The formwork holding device 1 is particularly applicable to formwork shut-offs of construction elements, such as lateral ends 22 or openings (windows, doors) (not shown) of integrated formwork wall 2, or full prefabricated wall (not shown), for example. The present invention illustrates an exemplary embodiment, wherein the formwork holding device 1 is used to maintain a formwork panel 3, in the form of a board for example of wood, at one of the lateral ends 22 of a formwork wall integrated 2. Of course, this example of use is not limiting.
    The formwork holding device 1, as illustrated in FIGS. 1 to 3, comprises a guide support 10 intended to be fixed to the construction element 2 by fastening means 14, in which a movable element 11 slides. comprising a support abutment 13, 112 arranged to be arranged against the shuttering panel 3. The movable element 11 and its bearing abutment has the shape of a bracket.
    The guide support 10 comprises a straight section tube 101 and hollow, square section, closed at one of its ends by a plate 102 provided with a through hole, and open at its other end. In the illustrated example, the guide support 10 consists of a single piece. The movable element 11 comprises meanwhile a first profile tube 111 rectilinear, hollow and open at one of its ends which forms a rectilinear portion. The first profiled tube 111 also comprises a square section which is smaller than the section of the profiled tube 101 of the guide support 10, to enable the sliding element 11 to be interlocked and slid into the guide support 10. guide 10 and the movable member 11 are thus mounted telescopically. As a result, the movable member 11 can move in a rectilinear translation with respect to the guide support 10 and the length L of the formwork holding device 1 is adjustable. Figure 3 illustrates the displacement of the movable member 11 relative to the guide support 10 between two positions to vary the length L of the formwork holding device 1 between the length L1 and the length L2. Advantageously, when the formwork holding device 1 is mounted on a construction element 2, the length L of the formwork holding device 1 can vary between at least one passive position in which said abutment stop 13, 112 is not in abutment against the shuttering panel 3 and an active position in which said abutment stop 13, 112 bears against it. In addition to being interlocked with one another, the guide support 10 and the movable element 11 are also interconnected by an endless screw, having a threaded rod 121 provided at one end with a regulating nozzle 122 and at the other end of a nut 123, and forming adjustment means 12, as shown in Figure 2. Indeed, the threaded rod 121 passes through the plate 102 through its through hole and the adjusting nozzle 122 is disposed externally and in abutment against the plate 102. In addition, the threaded rod 121 is included inside the profiled tube 101 of the guide support 10 and also included within the first profiled tube 111 of the movable element 11 and in which is fixed the nut 123. The threaded rod 122 is thus screwed into the nut 123. Π results that the rotation of the adjusting nozzle 122 in one direction or the other causes the translation rectilinear of the movable element 11 along the guide support 10 by screwing or unscrewing the threaded rod 121 in the nut 123. These adjustment means 12 thus make it possible to control the displacement of the movable element 11 with respect to the guide support 10. When the device 1 is mounted on a construction element 2, the adjustment means 12 make it possible to tighten the bearing abutment 13, 112 of the movable element 11 against the shuttering panel 3. To do this, it is sufficient to turn the adjusting end-piece 122 to bring the abutment abutment against the shuttering panel 3. According to an embodiment variant, not shown, the adjustment means are formed of an inverted worm in which the adjusting endpiece is this time not arranged at the closed end of the profiled tube 101 of the guide support 10 but at the end of the first profiled tube 111 of the movable member 11 at the right angle. Of course, any other equivalent adjustment means may be suitable such as a rack and pinion system or the like. The movable member 11 in the form of a square has a transverse portion 112 disposed at right angles to the rectilinear portion 111, as illustrated in Figures 1 to 3. The transverse portion is in the form of a second profiled tube 112 rectilinear, hollow or not, of square section, secured to the first profile tube 111 by welding or any similar method. This transverse portion is intended to be in direct abutment against the formwork panel 3 or via a steerable pad 13 when the formwork holding device 1 is in the active position. In the illustrated example, the profiled tube 112 comprises for this purpose a plurality of through holes 113 arranged to receive a hinge 133 of the steerable pad 13. The steerable pad 13 comprises a rectilinear section 131 and two transverse plates 132 projecting opposite the one of the other each having a through hole 134 facing one another and forming a stirrup disposed in the center of the straight section 131. This stirrup spans the second profiled tube 112 to the right of a through hole 113 to which it is coupled by a stud 133 forming the articulation of the steerable pad 13. The plurality of holes 113 of the second profiled tube 112 makes it possible to vary the position of the steerable pad 13 as a function of the thickness of the building elements 2. The rectilinear profdé 131 of the steerable pad 13 is arranged in the right angle delimited by the first profiled tube 111 and the second profiled tube 112. The steerable pad 13 is particularly suitable for very useful when the end 22 to form the building element 2 is not perpendicular to its walls 20 but is inclined or angled. This configuration is particularly illustrated in Figure 5 and will be described in the following description.
    The formwork holding device 1 further comprises fastening means 14 comprising a clamping flange 142 arranged to grip at least part of the guide support 10 and to be fastened to the construction element 2 by at least one fastener member. 141. In the example shown, the clamping flange 142 is formed of an L-shaped plate, and has a through hole 143 for receiving the fastener 141, which is a screw. This example is of course not limiting. In addition, the fixing member 141 is intended to be screwed into a socket (not shown) which is provided beforehand with the construction element 2. The screw 141 forms a fixing member of the fastening means 14 and the sleeve forms a complementary receiving member. This choice of fixing member 141 and receiving member is however not limiting. The fastening means 14 have the particular feature of being completely removable and independent of the guide support 10 and the movable element 11. Indeed, the fastening means 14 are on the one hand intended to be directly fixed in the element of construction 2 via the screw assembly 141 and bushing and to be in temporary contact with the face 201 of the construction element 2 via the curved portion of the plate 142, and secondly to be supported only without direct connection against the guide support 10 of the formwork holding device 1 via the right part of the plate 142.
    Figures 4 and 5 illustrate a non-limiting example of a building element 2 comprising a formwork holding device 1, as described above. In particular, in this example the building element consists of a prefabricated wall with integrated formwork 2. Of course, this choice of construction element is not limiting and extends for example to the solid prefabricated wall having lateral recesses. to receive links, or any other similar element of construction. In the example shown, the integrated form wall 2 comprises two walls 20 parallel to each other and spaced from one another to form a recess 21. The walls 20 each comprise a face 201. The integrated form wall 2 is manufactured in the factory and shipped to the site. The recess 21 is provided to receive the casting material of the core, such as concrete, once the integrated form wall 2 is placed on the job site. In this example, the integrated form wall 2 has a free lateral end 22, on which is supported a formwork panel 3 maintained by two formwork holding devices 1 to close this lateral end 22 of the integrated form wall 2 The formwork panel 3 thus makes it possible to ensure that the filling material of the core which is poured between the walls 20 does not flow out of these. The guide support 10 of the formwork holding device 1 is placed in abutment against the face 201 of one of the walls 20 of the integrated form wall 2. The guide support 10 and the rectilinear portion 111 of the movable element 11 are substantially parallel to the longitudinal direction of the integrated form wall 2. In addition, the transverse portion 112 of the movable member 11 is disposed opposite the lateral end 22 of the integrated form wall 2 and the shuttering panel 3. The steerable pad 13 is in turn against the shuttering panel 3 and forms an angle with the transverse portion 112 since the lateral end 22 and the shuttering panel 3 are slanted. Π is thus positioned automatically with respect to the casing end to exert a resistance force and maintain the shuttering panel 3 against the edges 221 of the lateral end 22 of the integrated shuttering wall 2 thanks to the adjustment means 12 The shuttering holding device 1 is fixed to the integrated shuttering wall 2 by the fixing means 14. More particularly, the guiding support 10 is held against the wall 20 by the clamping flange 142 of the fastening means 14. wall 20 comprises a sleeve (not shown) for receiving the fastener 141 which passes through the through hole 143 of the clamping flange 142 to allow the fastening means 14 to be fixed directly to the wall 20. The clamp of clampagel42 is firstly against the guide support 10 at its flat portion and secondly against the wall 20 at its curved portion.
    Possibilities of industrial application: It is clear from this description that the invention makes it possible to achieve the goals set, namely to propose a formwork holding device adapted to various construction elements and in particular standard integrated formwork walls, which is safe for operators, easy to implement by a single operator, capable of withstanding concrete thrust forces during casting, which avoids degradation of the construction element and preserves its integrity, and which considerably reduces the time of implementation and greatly improves the ergonomics of the site.
    The present invention is particularly applicable to concrete shuttering formwork including free end formwork or splay opening or sail head.
    The formwork method using the formwork holding device 1 previously described is now detailed. The guide support 10 is fixed to the face 201 of one of the walls 20 of the construction element 2 which comprises a bushing (not shown) via the fastening means 14. More particularly, the fixing member 141 in the through hole 143 of the clamping flange 142 which is oriented so that the bent portion bears against the wall 20, and the fastener 141 is inserted into the socket without tightening. Then, the guide support 10 is placed in abutment on the screw 141 in the space between the wall 20 and the clamping flange 142. As a result, the fastening means 14 are supported on the one hand against the guide support 10 and secondly against the face 201 of the wall 20. The formwork panel 3 is then placed between the slices 221 of the lateral end 22 of the integrated form wall 2 and the adjustable shoe 13 of the movable member 10. The movable member 11 is moved in a rectilinear translation along said guide support 10 to vary the length L of the formwork holding device 1 by turning the adjusting end-piece 122 by a appropriate key, until the steerable pad 13 exerts a resistance force against the shuttering panel. Finally, it closes the adjustment nozzle 122 to lock this position. After pouring and drying the concrete core, the formwork panel 3 is removed by performing the steps that are described in reverse.
    The present invention is not limited to the embodiment described but extends to any modification and variation obvious to a person skilled in the art.
