    FIELD OF THE INVENTION The invention relates to the field of construction and more particularly to a new structure of waiting box for connecting reinforcement.
    A waiting box is a support device for reinforcing links between two parts of a structure made of reinforced concrete, and which encloses the folded ends of the reinforcements, the apparent part of which is intended to be embedded in the concrete of the concrete. one of said construction elements.
    Previous art
    In known manner, during the construction of a building comprising several reinforced concrete elements, in particular walls or slabs, is positioned on the upper or lateral ends of said elements, metal reinforcements intended to ensure a mechanical connection with the adjacent elements, and to give cohesion to the whole.
    These metal reinforcements comprise a part which is embedded in the first element, and a second part which will be embedded in the adjacent element during its realization, in particular during the pouring of the concrete.
    These reinforcements must be held in place during the pouring of the concrete of realization of the first element, and are generally partially contained inside a device called waiting box, constituted of a box which encloses the folded ends of the reinforcements, while leaving exposed the part of the reinforcement that will be embedded in the concrete of the first element.
    For sealing against concrete, the box must be sealed. In the current state of the art, it can for example be closed by a polypropylene cover comprising a cross section in the shape of "U" and coming to fit inside the box. In other words, the branches of the "U" of the lid are slid inside the box.
    This closure technique of the box is not satisfactory and faces sealing problems. Moreover with this technique, the poured concrete slips between the sides of the box and the branches of the "U", and hinders the access to the frames.
    Another technique is to provide a flat cover which has on these two longitudinal edges arrangements allowing it to snap in a definitive manner on the free edges of the side walls of the box. The cover further has two parallel precut lines at said longitudinal edges.
    Thus, after pouring the concrete of the first element, it eliminates the lid that tears along the aforementioned pre-cut lines. In this way, the lid can be removed to reveal the ends of the frames that have been isolated from the concrete. Subsequently, unfolded ends of said reinforcements, intended to be embedded within the adjacent concrete element.
    However, a disadvantage lies in the fact that in this configuration, there always remain the arrangements of the lid latched on the free edges of the side walls of the box. These arrangements are in the form of two plastic strips (PVC) wedged between the poured concrete and the box.
    Another disadvantage lies in the fact that the waiting boxes must also be fixed for example on a metal sheet commonly used in the field of construction. The waiting boxes of the current state of the art generally include magnet devices reported at the ends of the rail, which causes in particular a greater separation of the reinforcements, which does not always meet the office plans of studies.
    EXPOSURE OF THE INVENTION One of the aims of the invention is therefore to remedy the aforementioned drawbacks by proposing a waiting box which can be easily fixed on a metal panel and in a manner in accordance with the expectations of the design offices. , ie in particular without generating an additional spacing of the metal frames.
    Another object of the invention is to provide a waiting box whose cover is removed easily and without disadvantages, in order to have free access to the folded parts of the connecting armatures. To this end, a waiting box has been developed for the installation of connection reinforcement between two parts or two concrete elements.
    According to the invention, the waiting box comprises: a rail defined by a bottom wall and two side walls, said rail being intended to receive a plurality of connecting frames, part of which crosses the bottom wall, and the other part of which is folded between the two side walls of said rail, a cover shaped to be mounted on the two side walls of the rail, parallel to its bottom wall so as to close off said rail and contain the folded parts of the connecting frames inside thereof, and at least two holding blocks of complementary shapes to the cross section of said rail, and intended to be arranged at the ends of the rail, inside thereof between the two walls lateral, said holding boxes: - include permanent magnets at their face intended to be opposite the rail cover once the rail closed; comprise at least one tubular cavity arranged longitudinally along the entire length of said block and in the vicinity of its base in contact with the bottom wall of the rail.
    Thus, the holding blocks allow the fixing of the waiting box on a metal sleeve by magnetization of said blocks on said metal sleeve and through the rail cover.
    These holding blocks are arranged inside the waiting box so that they do not interfere with its installation or do not cause additional spacing of the connecting plates.
    These holding blocks also make it possible to stiffen the rail and keep it in shape. Indeed, the holding blocks allow to maintain a constant gap between the side walls of the rail. This function of maintaining the gap between the side walls of the rail is also achieved by the cover on the rest of the length of the rail.
    In addition, the presence of at least one longitudinal tubular cavity constitutes a weakening zone of the holding block, which facilitates the subsequent removal of said block from the rail, after drying of the concrete. Indeed, the tubular cavity allows in particular to allow deformation of said blocks, promoting their removal from the rail.
    Preferably, the side walls of the rail each comprise an outer bulge formed longitudinally along the entire length of the rail. In this configuration, the side walls of the holding blocks, intended to be opposite the side walls of the rail, also each comprise a boss complementary to the longitudinal outer bulge and arranged longitudinally along the entire length of the block.
    In this configuration, each holding block comprises two longitudinal tubular cavities, extending at their boss. During removal as such, the bosses can be slightly retracted and more easily out of the bulges in which they are engaged, without causing any risk of tearing the cast rail in the concrete.
    The external bulge of the side walls of the rail makes it possible to optimize the subsequent anchoring of the rail in the cast concrete. In the same way, the boss of the side walls of the holding blocks makes it possible to ensure optimum retention of said blocks in the rail, and indirectly to optimize the fixing of the waiting box on a metal board.
    According to a particular embodiment of the invention, the cover comprises two longitudinal grooves intended to receive the free ends of the side walls of the rail.
    This feature allows to close the rail with a cover simply placed on top of said rail.
    According to another feature, the longitudinal grooves comprise a conformation allowing them to snap temporarily on the side walls of the rail. These arrangements are for example made by the outer faces of the grooves which terminate, at their free longitudinal edge, with a so-called whistle conformation, that is to say with a longitudinal bulge. This whistle conformation allows once the concrete poured around the rail, the cover can be easily removed without leaving an unnecessary part wedged between the concrete and the rail. The lid can be removed completely and easily. In the same way, the cover can be easily put in place thanks to the grooves intended to be snapped.
    The rail has a small thickness, especially less than one millimeter, so that the engagement of the free ends of the side walls in the grooves of the cover can be relatively difficult. In order to remedy this disadvantage and in order to optimize the engagement of the cover and thus the tightness of the inner housing defined by the rail and the cover, the free ends of the side walls of the rail are folded outwards to cooperate with each other. optimally with the grooves of the cover, and to cooperate with the whistle shape and generate the snap action.
    According to particular embodiments, the cover may be made of plastic, the rail may be metallic, and the holding blocks may be made of synthetic resin.
    Advantageously, and to prevent concrete from lodging in the tubular cavities of the holding blocks, they are closed at least at their ends, and preferably throughout their length, by a closure member. This closure member may be a simple plug, for example plastic, or a stuffing seal type element, otherwise called joint and well known in the state of the art.
    According to the invention, there is also a set of waiting boxes, according to which it implements a single holding block positioned at the junction zone of two consecutive waiting boxes.
    This ensures on the one hand, the straightness of the positioning of said waiting boxes, and on the other hand to fight against differences in level between two adjacent boxes and continuous, likely to emerge on a building site.

    DETAILED DESCRIPTION OF THE INVENTION The invention relates to a waiting box (1) used for the establishment of connecting armatures (2) between two parts or two concrete building elements (not shown).
    Referring to Figures 4 and 5, a waiting box (1) according to the invention comprises a rail (3) closed by a cover (4), and provided with two holding blocks (5) for fixing said box waiting (1) on a metal panel (not shown).
    Referring to Figure 1, the rail (3) is in the form of a thin section, for example metal, extending longitudinally. The rail (3) is defined in particular by a bottom wall (3 a) and two side walls (3b) giving it substantially a cross section in the shape of "U".
    The rail (3) comprises a plurality of connecting armatures (2) (only one being shown in FIG. 1). The connecting armatures (2) are intended to provide a mechanical connection between two adjacent elements of a concrete structure, and thus confer cohesion to the assembly. For this purpose, a first portion (2a) of the connecting armatures (2) is intended to be embedded in a first element of a concrete structure. The second part (2b) of the connecting armatures (2) is intended to be subsequently embedded in a second element of an adjacent concrete structure. For this purpose, the connecting armatures (2) are placed on the bottom wall (3a) of the rail (3) of the waiting box (1). These connecting armatures (2) protrude firstly from the bottom wall (3a) of said rail (3), on the side opposite to the side walls (3b), and are folded on the other hand, to be contained between the two side walls (3b) of said rail (3). In other words, the first part (2a) of the connecting armatures (2), intended to be embedded in the first element of a concrete structure, protrudes from the bottom wall (3a) of the rail (3). , and the second part (2b) is folded inside said rail (3), and protected by a cover (4) intended to close the rail (3) of the waiting box (1), and thus prevent that the concrete does not flow inside said rail, during the realization of the first part of the concrete structure.
    The side walls (3b) of the rail (3) each comprise an outer bulge (6) formed longitudinally along the entire length of the rail (3). This bulge (6) prevents the removal of the rail (3) once the concrete poured around.
    The free ends of the side walls (3b) of the rail (3) are folded to form a hem (3c). This hem (3c) avoids having protrusions that can cause injuries during handling, but also facilitate the subsequent introduction of the cover (4) for closing the volume defined by the rail.
    Referring to Figure 2, the cover (4), made for example of plastic, is shaped to be mounted between and on the two side walls (3b) of the rail (3), parallel to its bottom wall (3 a) in order to close off said rail (3) and to contain the folded parts (2b) of the connecting armatures (2) inside thereof.
    The cover (4) has a generally flat shape and comprises two longitudinal grooves (7) provided along the entire length of said cover (4) and at its longitudinal edges. These grooves (7) are for example formed by two parallel flanges protruding perpendicularly from the plane of the lid. These grooves (7) make it possible, on the one hand, to provide a seal between the cover (4) and the rail (3) and, on the other hand, to block the side walls (3b) of said rail (3). . Indeed, the side walls (3b) of the rail (3) can not fold inward during thrusts exerted by the concrete after casting, which would hinder access to the frames (2b) and their unfolding.
    The grooves (7) are of complementary shape to the free ends of the side walls (3b) of the rail (3), and are intended to receive them in engagement and snap-fastening for example for the closure as such. More specifically, it is the hem (3c) which is engaged in said grooves (7).
    Referring to Figure 2a, the longitudinal grooves (7) comprise a conformation allowing them to snap temporarily on the side walls (3b) of the rail (3). These arrangements are for example made by the external faces of the grooves which terminate, at their free longitudinal edge, with a so-called whistle conformation (7a). This whistle conformation allows, once the concrete poured around the rail (3), the cover (4) can be easily removed without leaving an unnecessary part wedged between the concrete and the rail (3). The lid (4) can be removed completely and easily. In the same way, the cover (4) can be easily put in place thanks to the grooves (7) intended to be snapped in particular by cooperation of the hem (3c) and the whistle (7a).
    With reference to FIG. 5, the cover (4) is then able to close the rail (3) of the waiting box (1) by snapping on it, while projecting slightly over the side walls (3b) of said rail (3), and more precisely on the hem (3c). Given the fineness of the lid, no part (4) remains stuck between the cast concrete and the rail (3) during the construction of the concrete workpiece.
    Referring to Figure 3, a block (5) for holding, for example made of synthetic resin, such as polyurethane resin, comprises a parallelepiped shape complementary to the cross section of the rail (3).
    The block (5) for holding is intended to be disposed at one end of the rail (3), a block (5) at each end, between its two side walls (3b). The holding block (5) makes it possible to secure the holding box (1) to a metal box. It comprises in this manner permanent magnets (9) at its face intended to be opposite the cover (4) of the rail (3) once the rail (3) closed. The block (5) may comprise for example four permanent magnets (9) arranged substantially at the four corners of said block (5).
    The side walls (5a) of the block (5) for holding, intended to be opposite the side walls (3b) of the rail (3), each comprise a boss (10) complementary to the longitudinal outer bulge (6) formed on the rail (3). The bosses (10) are formed longitudinally along the entire length of the block (5). These bosses (10) are intended to cooperate with the external bulges (6) when the block (5) for holding is engaged inside the rail (3). This characteristic makes it possible to optimally maintain the block (5) in the rail (3), and therefore to optimize the fixing of the block (5) on a metal board.
    According to a feature of the invention, the block (5) for holding comprises a tubular cavity (11) at each boss (10) which it is provided. This tubular cavity (11) is formed in particular longitudinally in the block (5) and over the entire length thereof. These tubular cavities (11) make it possible to easily remove the block (5) when engaged in the rail (3). Indeed, these tubular cavities (11) allow a deformation of the bosses (10) during removal of the block (5).
    This deformation allows the retraction of the bosses (10) to allow the removal of the block (5), without risk of tearing the rail out of the concrete constituting the first element of the concrete structure to be realized
    Advantageously, in order to facilitate the removal of the blocks (5) after casting of the concrete, there is defined within the latter recesses or recesses (13), allowing the introduction at this level by the operator of a tear-type hammer -clou, able to leverage.
    To avoid, during casting, that concrete penetrates into said tubular cavities (11), they are closed throughout their length by shutoff members (12) such as elements known as "joint bottoms" well known of the state of the art.
    FIG. 6 illustrates the use of two waiting boxes positioned in a continuous and collinear manner, a situation that is frequently encountered on construction sites.
    Three rails (3) are thus shown, which one wishes to position in the extension of one another on a banche. A magnetic block (5) of the type previously described is positioned astride between two consecutive rails.
    In doing so, besides the fact that reducing the number of these blocks, helping to lower the cost of realization of the walls thus made, it ensures the straightness of the positioning of the rails, and therefore the corresponding waiting boxes.
    As is apparent from the foregoing, the invention provides a waiting box (1) which can be easily attached to a metal panel and in a manner that meets all the requirements of design offices, ie in particular without creating additional spacing of the connecting armatures. The invention also provides a waiting box (1) whose lid (4) can be easily removed, after drying of the cast concrete, in order to have access to the folded parts of the connecting plates (2), without leaving any material superfluous stuck in the concrete.
