The device of the invention will be described to support and fix a gutter hook to a roof covering, but it is understood that it can be intended to support and fix any other construction accessory in the building field.

Referring to the figures, reference numeral 1 designates a device for supporting and fixing a gutter hook, comprising a one-piece assembly made of one-piece material comprising a part forming a clamp 2 and a part 3 forming a hook-holder .

This assembly is formed from a metal strip or double-bent strip in opposite directions to form on the one hand the clamp 2 with two straight upper and lower 4 upper and lower branches 5 and on the other hand the hook holder part 3 constituted by a rectilinear arm extending the lower branch 5 of the clamp 2 and forming, via the corresponding bend 6, a determined angle α that can vary by deformation of the bend to adjust to the slope of a panel or pan PC roof cover of a building for horizontally suspending a gutter, not shown.

The arm 3 may include a rectilinear central lumen 7 for passing a bolt 8 for detachably fixing the gutter hook 9 consisting of a hoop 9a concavity-shaped conjugate to the external convex surface of a gutter and d a rectilinear arm 9b can be fixed in support on the face 3. The light 7 of the arm 3 makes it possible to selectively adjust the height position of the gutter hook 9 and to block it by the bolt 8 at a position determined according to the cover to which the device must be fixed. 1.

According to a variant not shown, the arm 3 and the gutter hook 9 can be made in one piece.

According to the invention, the two branches 4, 5 of the clamp 2 are substantially parallel and of the same length and able to elastically grip the edge B of the roof covering panel PC so that the internal faces of the two branches 4, 5 in contact respectively on the corresponding upper and lower faces of the edge B of the PC cover panel are fixed to this pan thanks to the friction generated by the clamping by bringing the two branches 4, 5 closer to each other. Thus, the clamp 2 can be attached to an edge of a PC cover without using a fixing screw. Experiments have shown that the clamp can withstand a stripping force of the edge B of the PC cover pan up to 750 Newtons, while the existing clamps only withstand a force of less than 500 Newtons.

The figures 4 and 5 represent the device 1 of the invention attached to a lower edge of a corrugated roofing plate of a roof of a given slope. The two branches 4, 5 of the clamp 2 of this device energetically grip the edge B of this panel extending longitudinally along an edge of one of the corrugations of the panel, in this case the edge constituting the top of a ripple.

The establishment of the device 1 is effected by forcibly engaging the two branches 4, 5 of the clamp 2 on the corresponding edge B of the roof covering panel by a thrust force F exerted on the elbow 10 connecting one to the other the two branches 4, 5 to using a tool, such as a hammer. Thus, the fixing of the clamp 2 on the edge B of the cover panel PC uses the clamping force tending to bring the branches 4, 5 of the clamp closer to one another and due to the bend 10

The inner face of each branch 4, 5 of the clamp 2 may be smooth, but at least one of the faces of the two branches 4, 5 may be provided with grooves or notches 11 as shown in FIGS. Figures 1 to 5 where the inner face of the upper branch 4 is provided with such notches or grooves and which may be arranged chevron or perpendicular to the longitudinal direction of the corresponding branch 4, 5.

The presence of such notches allows the clip to withstand greater PC cover board edge tearing forces greater than 750 newtons. The two branches 4, 5 of the clamp 2, instead of being flat rectangular cross-section, may have a substantially omega-shaped cross-section in such a manner that the outwardly convex portion of the omega branches extends all the way downwards. these passing through the elbow 10 connecting one to the other of these two branches as it appears better from Figures 1 to 3 .

By this configuration of the two branches 4, 5, the inner face of each branch is defined by the two straight flat walls located on either side of the outwardly convex portion of these branches.

The Figures 6 to 8 represent an alternative embodiment allowing the clamp 2 of the device 1 to grip a lower edge B of a PC cover panel said steel tray when the thickness of this edge is less than the gap between the two branches 4, 5 of the clamp 2.

For this purpose, a shim 12 may be interposed between at least the upper branch 4 of the clamp 2 and the upper face of the lower edge B of the cover panel PC so as to grip this edge between the face 12a of the wedge 12 opposite the branch 4 and the inner face of the lower branch 5 of the clamp 2. The wedge 12 is flat and mechanically fixed to the upper branch 4 of the clamp 2 by any appropriate means. The figure 6 shows such a mechanical attachment can be effected by two upper side walls 12b of the shim 12 provided at their upper edges with several internal projections 12c facing each other defining with the bottom of the wedge 12 a groove in which s engage the two flat side walls of the branch 4 omega. The wedge 12 constitutes, in a way, a kind of holster that can be slipped on the upper branch 4 of the gripper 2.

The figure 8 shows that the inner face of the upper branch 4 of the clamp 2 is provided with ridges or notches 11 adapted to bear tightly against the bottom of the shim 12 when the clamp 2 encloses between its two branches 4, 5 this shim and the corresponding edge B of the PC cover panel. In addition, the face 12a of the shim 12 opposite to the upper branch 4 may also include ridges or notches 13 bearing tightly on the upper face of the edge B of the cover panel PC. In this way, the clamp 2 and the shim 12 can withstand a tensile pulling force of the edge B of the cover panel PC.

As previously described, once the shim 12 secured in the clamp 2 to the upper branch 4 thereof, the establishment of the device 1 is effected by forcing the clamp 2 and the shim 12 on the lower edge B PC cover panel using a hammer exerting a thrust force on the elbow 10 of the clamp 2 so as to grip the corresponding portion of the lower edge B of this panel between the shim 12 and the lower branch 5 of the clamp 2. The figure 6 shows that the portion of the lower edge B of the PC cover panel sandwiched between the shim 12 and the lower branch 5 of the clamp 2 is constituted by a part flat longitudinal edge constituting the small upper base of a substantially rectangular trapezoidal corrugation of the PC cover panel.

According to an alternative embodiment, the shim 12 can be simply fixed by gluing to the inner face of the upper branch 4 of the clamp 2 and the face 12a of this shim opposite the branch 4 can comprise an adhesive coating with microcapsules breaking or grinding under the mechanical force of introduction of the clamp 2 on the edge B of the cover panel PC to release the adhesive and the hardener they contain, while mixing them to ensure a grip by gluing of the shim on the upper side of the lower edge B of the PC cover panel.

Alternatively, the shim 12 may simply be coated with an adhesive coating before placement on the bottom edge B of the cover panel PC.

The shim 12 may be made of any suitable material, for example steel, stainless steel, copper, aluminum, plastic or elastomer. In the case where the shim 12 is made of an elastomeric material, this shim can be held between at least one of the branches 4, 5 of the clamp 2 and the edge B of the cover panel by elastic deformation of the shim exerted by the clamping force of the clamp 2.

The figure 9 represents an alternative embodiment of the wedge 12 which is double in having a U-shaped shape matching the shape of the clamp 2 so as to be housed therein. The two parallel branches 12d of the shim 12 are secured to the inner faces of the two upper 5 and lower 4 branches of the clamp 2 in the same way as the shim 12 of the figures 7 and 8 , that is to say either by gluing or by streaks or notches present on the inner faces of the branches 4, 5 of the clamp 2 and coming into contact with the branches 12d of the shim 12.

Once secured in the clamp 2, the double shim 12 defines between its two branches 12d a slot into which can be inserted the lower edge B of the cover panel PC once the clamp 2 is placed on this edge so that both branches 12d of the wedge 12 enclose this edge by pinching exerted by the two branches 4, 5 of the clamp 2 on the branches 12d of the wedge 12.

The installation of the clamp 2 and the double shim 12 on the lower edge B of the cover panel PC is also performed using a hammer exerting a thrust force F on the elbow 10 of the clamp 2 to force the edge B between the branches 12d of the wedge 12.

At least one of the branches 12d of the shim 12 may have on its inner face an adhesive coating for fixing the shim 12 to the edge B and this adhesive coating may comprise microcapsules triggering the attachment by bonding the branch 12d to the edge B at the time of installation of the clamp assembly 2 and wedge 12 at this edge.

The clamp 2 as described above can be made of steel, stainless steel, copper, aluminum or a reinforced plastics material.

The clamp can adapt to the slope differences of the roof covers by a permanent deformation of the elbow 6 connecting the arm for 3 to the lower branch 5 of the clamp 2 so that the arm 3 occupies a substantially vertical position.

The figure 10 represents an alternative embodiment of the device 1 of the invention and according to which the hook-carrying arm 3 comprises, respectively along its two opposite parallel longitudinal sides, two flanges 3a, 3b constituting guide rails adapted to receive and guide opposite longitudinal longitudinal edges of the arm 9b of the gutter hook 9 so that the arm 9b is maintained in alignment with the arm 3 after attachment to the latter by the bolt 8.

The device of the invention is preferably applied to a corrugated sheet, fiber cement, sheet or PVC roof covering and to a roof covering made of steel or dry pan, but it can also be applied to tiles roof covering.

The assembly of the device of the invention to a roof covering does not require screwing and is simply carried out with the aid of a hammer, which results in an extremely fast installation of this device to the roof covering .
