Description

TECHNICAL AREA

The present invention relates to the field of accessories used in the construction of works using a poured construction material regardless of where the material is poured: on site or partially in the factory, etc., for example Poured concrete. More particularly, the present invention relates to the holding boxes used in the recovery for example of at least one wall and preferably two concrete elements, two concrete walls or two concrete slabs.

STATE OF THE ART

Conventionally, a standby box or waiting box comprises a plurality of steel connecting frames, a bottom comprising a bottom wall and two side walls delimiting a receiving space, a cover arranged facing the wall of bottom and at least partially closing the standby box. The connecting reinforcements are made of steel and each comprise a loop and two strands, the strands are arranged in the bottom receiving space and extend in a first direction and the loops extend in a second direction intersecting the first direction, projecting from the standby box. Thus, when concrete elements are formed on the standby box, to link the first element to the second, it is necessary to unfold the strands so that the latter join the two elements together. In specific cases, the reinforcements of connections can be with a strand, a loop or with two strands without loop, or carried out in cable or other.

Up to now, each concrete reinforcing iron has been forcefully retracted into the standby box by its strands, and more precisely each strand of each iron has been inserted into a separate hole previously formed on one face of the standby box. This manipulation is tedious, noisy and dangerous because generating risks of cutting the worker, the irons being sharp. Once all the irons are in place, the worker turns over the standby box and stores the protruding strands in order to position a cover closing the standby box. This second manipulation can also prove to be dangerous, taking into account the fact that the strands of irons are numerous and their point injurious and erect upwards, while the worker tidies them up. In addition, these operations are long and repetitive.
