EP0855467A2 - Fixing device for trellis for stabilisation of covering - Google Patents

Abstract

The fixture consists of a base (3) which is fixed to the supporting surface by a fastener (5) and has a spacer leg (9) with a hook-shaped end (10) to engage with the mesh or rod. The spacer leg (9) has a support (11) for the trellis section or rod engaged with the hook, with the edges (12,14) of the support and hook offset relative to one another for easy fitting of the fixing. The fixing can be made from metal or plastic, depending on requirements.

Description

In the field of construction, including engineering civil, old infrastructures sometimes require work of renovation and reinforcement. Generally, a metal frame of stabilization is integrated into the renovation or reinforcement layer.

The frame is most often a trellis comprising rods metal bars that should be fixed to the support before pour or spray the coating.

The invention originates from a problem of fixing trellis.

There are two ways to attach the trellis to the support.

The first method of fixing consists in pressing the trellis at the support, using holding jumpers and anchors jumpers, or as an example, using metal bands that we close around the trellis rods and fix to the ground using a fastening element to form a retaining eyelet integral with the support material.

It is also possible, according to the second more efficient method of attachment, position and fix the mesh at a distance from the support material, for better reinforcement of the support.

Remote holding and fixing parts, objects of FR-8804232-A1, each include a ground support base, pierced with a orifice for the passage of a fastening element, extended by a part of inclined spacing on the support base and whose free end folded is intended to be closed around a trellis rod using a pinch device. Positioning of the rod relative to the ground is adjustable by tilting the spacer. The laying of these parts is long and tedious especially because of the stages of pinching and positioning relative to the ground. In addition, the positioning is fragile and the distance between the trellis and the ground risks to be damaged, especially during the passage of workers.

Another piece, intended for fixing the rod only, object of US-3870428, also includes a support base intended for be anchored to the ground using a fastening element, integral with a part central folded at right angles with the folded free end forming a hook for attachment to a horizontal rod positioned relative to the ground at means of amounts.

The use of such a system with positioning uprights and fixing parts is complicated and heavy.

The invention aims to position and securely fix a trellis to distance from the support material, quickly and easily.

To this end, the invention relates to a fixing part of a coating stabilization mesh, or rod, to a material support, comprising a support base intended to be anchored to the material support, integral with means for receiving a strand of trellis or the rod, by means of a spacer leg, characterized by the fact that it comprises means for supporting the strand of lattice, or the rod, received in the receiving means.

Thanks to the invention, it suffices to introduce the trellis strand into the means of receiving and anchoring the support base to the ground, without it being necessary to close the receiving means around the rod.

In addition, the part allows to fix strands of trellis or rods of different dimensions.

Advantageously, the reception means and the means support are offset laterally with respect to each other, in order to facilitate the introduction of the strand, or rod, in the means of reception.

Preferably, the spreader leg is extended laterally by a support wing having a support edge for the strand of trellis or rod.

More preferably, another edge of the support wing plays the role of additional support leg of the fixing piece against the support material.

Thanks to this, the stability of the fixing piece is improved.

In a preferred embodiment of the invention, the folded free end of the spreader leg is arranged in means receiving strand or rod.

The invention will be better understood with the aid of the following description of a preferred embodiment of the fastener of the invention, with reference to the appended drawing in which:

• Figure 1 shows a perspective view of the fastener;
• Figure 2 shows a rear view of the fastener of Figure 1;
• Figure 3 shows a side view of the fastener of Figure 1 during fixing; and
• FIG. 4 represents a view of a strand of trellis during two fixing steps.

Fasteners 1, such as that shown in the Figure 1, are intended to fix a stabilization coating liner to a support material 2, at a distance from the support material 2.

In the particular example of the description, the material support 2 is a pavement intended to be covered with a layer of bitumen in which the trellis is integrated, comprising a plurality of stems, or "strands", intertwined forming a frame to fight against deformations of the paved road.

The fixing part 1, here made of sheet metal, comprises a support base 3, here rectangular, pierced with an orifice 4 of passage of a fastening element 5, in this case a buffer comprising a rod with a pointed free end and another end supporting a support head.

The orifice 4 is formed at the top of a protruding truncated cone of the support base 3, and has a substantially equal opening diameter the diameter of the rod but less than the diameter of the head of the tampon.

The pointed end portion of the pad 5 is surrounded by a ring 6, here made of plastic, for guiding in the fixing tool.

The rectangular support base 3 is extended, on one side, by a spacer 9 making a substantially right angle to the support base 3. The free end 10 of the spacer leg is curved in the shape of a hook, on the side opposite the support base 3, so to form a fold 10 for receiving and hanging a strand of trellis 100.

The spacer leg 9 is extended laterally by a wing support 11, folded at right angles to the leg 9, opposite the support base 3 and offset laterally with respect to the fold 10, in order to facilitate the introduction of the mesh strand 100 into the receiving fold 10 as will be explained later.

The support wing 11, of substantially rectangular shape, includes an upper edge 12 for supporting the mesh strand 100 introduced into the receiving fold 10, parallel to the support base 3, and a lower edge 13 of additional support of the fixing piece 1 against the carriageway 2, parallel to the upper bearing edge 12 and extend in the support base plan 3.

The height of the support wing 11, in other words the distance separating the two bearing edges, upper 12 and lower 13, defines the elevation height of the trellis 100 relative to the pavement 2 for the fixation.

On the other hand, the distance between the strand support edge 12 and the bottom of the receiving and hanging fold 10 defines the diameter maximum trellis strand 100 that can be received in the fold 10.

Finally, note that the lateral edge 14 of the free end of the fold, adjacent to the support wing 11, is cut at an angle to further facilitate the introduction of the strand 100 in the fold 10 after passage between the edge side biased 14 and the upper bearing edge 12. The width of the passage of introduction equal to the distance separating these two edges 12, 14, is substantially equal to the maximum diameter of the mesh strand 100. The edge 14 could also be curved.

After the structural description of the fastener, its use for fixing a mesh strand 100 will now be described.

The fixing consists first of all in introducing the strand 100 into the receiving fold 10, then anchoring the support base 3 in the material support 2.

For the introduction of the strand 100 in the fold 10, and in reference in FIG. 5, the fixing piece 1 is inclined relative to the strand 100, the biased edge 14 of the fold 10 being positioned parallel to the strand 100.

The fixing part 1 is then engaged on the wire strand 100 which has passed through the introductory passage between the edge biased 14 of the fold 10 and the edge 12 of strand support. The lattice strand 100 is thus attached to the fixing part 1.

Then we rotate the fastener 1 around the support edge 12 until the support base 3 is pressed against the roadway 2. Finally, the buffer 5 is forced into the roadway 2, to anchor the support base 3. The receiving and hanging fold 10 blocks the strand of mesh 100 upwards and thus maintains the distance between strand 100 and floor. By anchoring the support base 3, if necessary, we pull the strand of 100 lattice towards the pavement.

A metal fastener has been described above. Of course, we could also consider carrying it out in terms of plastic, according to a conformation adapted to this kind of material.
