Definitions

  • a waiting box is a support device for frames of connection between two reinforced concrete construction elements, which contains the portions of the reinforcements, the visible part of which is intended to be embedded in the concrete of one of the building elements.
  • the reinforcements In known manner, the reinforcements must be kept in place of the casting concrete, and are usually partially contained inside a device called "waiting box", and made up of a box which contains ends folded of the reinforcements, while leaving visible the part of the reinforcements which will be drowned in concrete. After pouring the concrete, we eliminate the waiting box for show the ends of the reinforcements that have been isolated from the concrete. The folded ends are then unfolded, and are then embedded inside the adjacent item.
  • This box is made from cellular polypropylene, whose channels are parallel to the large direction of the waiting box.
  • transverse slot which is crossed by the central part of the reinforcements during their installation in the box.
  • This transverse slot which covers the almost the entire width of the box constitutes a risk of leakage. Indeed, under the effect of the pressure of the concrete, this transverse slot can have tendency to open slightly, and to let the laitance of the concrete pass.
  • the waiting boxes described in the aforementioned document have a limit of their resistance limited to the pressure exerted by the concrete during the casting.
  • the objective of the present invention is therefore to overcome these various disadvantages, by proposing a box of waiting box which presents a strong rigidity while being extremely easy to extract, whose sealing properties are superior to similar solutions of the prior art.
  • this box is characterized in that its rear face has a fold oriented towards the inside of the box. This fold has an edge which is located at the front face, between the flaps of the latter.
  • the rear face of the box is configured in such a way that part of the sheet which constitutes it is present near the face before. In this way, during the extraction of the box, the user can split the face rear of the box by cutting the characteristic fold, which is not at the contact with the concrete, but on the contrary on the side of the front face of the box, and therefore easily accessible.
  • this characteristic fold constitutes a reinforcement longitudinal which is present between the front and rear faces of the box.
  • the rigidity of the box is therefore increased, and therefore its resistance to the pressure exerted by concrete during pouring.
  • the characteristic fold may have recesses at its edge.
  • the quantity of material to be cut for the extraction operation is limited to only the zones of presence of the sheet foldable on the edge of the characteristic fold.
  • these recesses may have a certain width, or else still be reduced to a simple slit.
  • the fold may have lights connecting the passage openings of the same metal frame.
  • these lights constitute notches inside the fold characteristic, in which the central parts of the reinforcements can come house, without modifying the position of the fold inside the box.
  • These lights made in the fold are therefore more particularly advantageous to facilitate the fitting of frames in the waiting box. They allow reinforcements to cross the rear face of the box without causing deformation excessive withdrawal.
  • the recesses made at the edge of the folds can be connected to the lights connecting the passage openings metal frames.
  • the areas of material to be cut present on the edge are located between the positions of each reinforcement.
  • the box can include a wire located inside the fold, at the edge of the latter, intended to facilitate the tearing of the fold when extracting the waiting box.
  • the box is equipped with a rigid wire, which can be metallic or synthetic, or which is generally strong enough to cause tearing of the material of the box when the user exercises sufficient traction.
  • the box can have two flaps ends, ensuring the closure of the waiting box.
  • Each end flap can be made up of several individual flaps separated at the fold of the face back.
  • each end flap consists of two flaps separated, defining between them an area which can be crossed by the rigid wire of cutting. This decomposition of the end flap into two separate portions also facilitates the extraction of the waiting box, since the halves of the box, located on either side of the characteristic fold can be extracted independently of each other.
  • the waiting box can be made from two independent half-sheets, joined, for example by an adhesive, to the level of their facing edges, so as to form the edge of the fold feature.
  • the invention relates to a waiting box box which can be produced from a sheet of a pliable material such as water-repellent cardboard, pliable plastic or synthetic materials, and for example cellular polypropylene.
  • a pliable material such as water-repellent cardboard, pliable plastic or synthetic materials, and for example cellular polypropylene.
  • the application can for example can be obtained from the cut sheet illustrated in Figure 1.
  • This sheet (1) comprises different parallel areas intended to form the different faces of the box.
  • the sheet (1) comprises two zones (2, 3) which are intended to form the back of the box after folding.
  • the zones (2, 3) are bordered towards the outside two zones (4, 5) which will form the lateral zones of the box after folding.
  • the lateral zones (4, 5) are connected to flaps (6, 7) forming each half of the front face of the box.
  • All outside, the shutters (6, 7) are connected to flaps (8, 9) which are folded towards the inside of the box, to form an area serving as a spacer between the rear and front faces.
  • the edge (14) of the fold (15) is strongly perforated by the presence of recesses (16). Between two recesses consecutive (16), the edge comprises a portion (17) which connects the two halves of the leaf in a transverse direction.
  • the quantity of matter present at the level of the edge (14) is relatively reduced, in comparison with the total length of the caisson.
  • the two halves (2, 3) of the rear face have openings (20) intended to allow the passage of the reinforcements metal, some of which are shown in Figure 2.
  • These openings (20) are interconnected by slots (21) which extend from the opening (20) and over the entire length of half (2, 3) of the rear face. So, after folding, the slots (21) connected to the openings (20) each occupy a little less than the half the width of the box. They therefore have better resistance to deformation and opening than similar slits observed in boxes of the prior art which on the contrary extend over the quasi width of the box. The tightness of the box according to the invention is therefore significantly improved.
  • these slots (21) are connected to lights which extend almost over the entire width of the central zone (10) intended to form the fold (15).
  • These lights (22) have a width, measured in the direction longitudinal of the box, which is slightly greater than the diameter of the reinforcements intended to be placed in the box. So when the leaf is folded over to give the box structure illustrated in FIG. 2, these lights (22) form notches intended to be crossed by the central portion (44) of a frame (45), when the latter is placed in the box. The presence of these notches prevents too much deformation of the fold (15) during introduction reinforcements.
  • the central fold (15) When mounting the box, as shown in Figure 2, the central fold (15) has a height substantially equal to that of the box, so that it forms a spacer increasing the resistance of the box to crushing. This crush resistance is further increased by the presence of the flaps (8, 9) which also have a width substantially identical to the height of the fold (15). In this way, the central part of the box has four longitudinal elements present between the front face and the rear face, which therefore increases the rigidity of all.
  • the box (30) can accommodate a wire intended to facilitate the opening of the box. More precisely, this wire can be metallic or even a sufficiently rigid wire to allow to tear the material of the box. This thread is put in place it by sliding it between the two walls (11, 12) which form the fold (15). The introduction of this wire is made possible by the fact that the end flaps (23, 24) form two separate flaps, which each seal one half of the box. These flaps (23, 24) have flaps (25, 26) intended to penetrate inside the box during folding. To ensure a perfect seal, additional flaps (27, 28) are provided at the ends of the side faces (4, 5). relative of the two box halves is provided by the loop (44) of the frames.
  • the use of a wire as illustrated in FIG. 3 is not essential, but it can be replaced by a cutting operation carried out with a cutting tool which is slid between the two walls (11, 12) of the fold (15).
  • a cutting tool which is slid between the two walls (11, 12) of the fold (15).
  • the presence of the longitudinal slots (16) decreases the amount of material to cut and therefore facilitates extraction operations, it is not compulsory, and the invention therefore covers the variants in which the edge (14) is not interrupted only by the lights (22) forming the slots for fitting the frames.
  • the waiting box can be constituted by the assembly of two half sheets (41) as illustrated in FIG. 5.
  • This assembly can be obtained by an adhesive, stapling, welding, or any other means, at the edges (42) opposite. If the half-plates are of different dimensions, it is possible to combine them to widen the range of waiting boxes subject to the invention.
