Metal support device for rebar »

The present invention relates to a metal support device 5 for reinforcing bars, intended mainly to serve as a support and spacer for longitudinal reinforcements in reinforced concrete and in particular in the construction of roads in continuous reinforced concrete. In the last application, this support device, thanks to its constitution, serves at the same time as a transverse 10-fold frame.

The supports generally used in constructions to maintain the distances of the reinforcements between them and reinforcements with regard to the forms, are too expensive by their shape and their manufacture and lend themselves only with difficulty to the reinforcement of the reinforced concrete roads. .

The object of the present invention is therefore to create a support device, the production of which requires only a reduced workforce and can be produced from steel wire and concrete rods of cross section and length. variables according to the prescriptions imposed by the project manager.

This object is achieved by the device according to the invention which comprises a series of stirrups made of a steel wire which is bent so as to preferably form a triangle whose base \ touches the ground, one of the ends of the wire being folded so a. form an eyelet which is at the top of the triangle and move away from the latter by pointing upwards; as well as a concrete round which passes through the said eyelets in a direction preferably perpendicular to the plane of the triangles and which is fixed to each of the said eyelets by welding.

According to the invention, the base of the concrete round which is located between the top of the eyelet and the end of the wire which points upwards, forms the seat of a longitudinal reinforcing bar, while 5 -2 - * that said end, folded over said longitudinal bar by a hammer blow after installation, ensures its maintenance.

The assembly constituted by the stirrups, the transverse concrete rod and the longitudinal reinforcing bars is a rigid assembly, perfectly meeting the requirements required for the road in continuous reinforced concrete, while being achievable with ease and at a price of 10 is particularly advantageous.

Other characteristics and advantages will emerge from the description of the drawing, or FIG. 1 represents in a nonlimiting manner a bias view of a preferred embodiment of the device according to the invention.

There are the stirrups (1) which are formed by a steel wire of sufficient length and adequate thickness for the constraints. As can be seen, it suffices to form a stirrup (1) to bend the wire in two places to obtain the base and the two sides of a triangle; then a third folding is carried out which results in the formation of a circular eyelet (2) located at the top of the triangle and the remaining end (3) of the wire is allowed to point upwards.

25 ^ It is understood that this end (3) is slightly separated at (5) from the plane of the triangle.

We choose an adequate number of these stirrups (1), we place them * 30 next to each other, we introduce in the eyelets (2) a concrete ring (4) and we fix the round (4) to the eyelets ( 2) by welding.

The design of the stirrup makes it possible to fix in a particularly advantageous 35. longitudinal rebar on the support; in fact, it suffices to place the longitudinal bar (6) on the seat formed by the concrete ring (4) at the place situated - 3 - t between the eyelet (2) and the free end (3) of the wire which points upwards and fold this end (3) over the bar (6) with a hammer blow.

5 It is understood that the invention is not limited to the embodiment shown and that there are many variants accessible to those skilled in the art, without departing from the spirit of the invention.

10 These variants relate in particular to the arrangement of the stirrups with respect to the transverse rounds resp. longitudinal bars, the spacing of the stirrups which can be regular or non-regular and the sizing of the steel wires, rounds and bars.

It should be noted that an additional advantage of the support device according to the invention lies in the fact that the means necessary to achieve the rigidity of the assembly can be summed up in the use of hammers.
