Definitions

• the present invention relates to the field of brackets used in insulation. These brackets are used to maintain insulation on a wall.
• This insulation is in the form of insulating panels (rolled or not). For example, it is possible to fix these insulating panels by stapling or gluing them.
• bracket 1 As visible in Figures 1 and 2.
• a bracket 1 consists of a fixing plate 2 designed to be fixed to the wall and a holding plate or plug 3 monoblock with said plate of fixation.
• This holding plate 3 extends perpendicularly from the fixing plate 2 to give the whole a form of L.
• the insulating panel P is then socketed or wedged on the edge of the holding plate 3 on said bracket 1 and then plated on the wall M as shown in Figure 2 showing a view from above.
• the bracket is then used to support a metal or wooden structure S allowing the assembly of additional elements such as a second set of secondary frame H or directly of the type of cladding elements (facings facings of any kind, cassettes, clapboard, cladding, plasterboard ).
• This square undergoes, during the plugging step and after, stress or mechanical forces exerted by the insulating panel P. These mechanical forces are mainly applied to the holding plate 3 which tends to deform elastically. The risk is to have a deformation that becomes plastic see a propagation of mechanical forces at the interface between the fixing plate and the holding plate may break said bracket.
• reinforcement means 103 are used. These reinforcement means 103 are arranged at the level of the fixing plate and the holding plate. These reinforcing means comprise at least one stiffener 1030 in the form of a plate mechanically linked to the fixing plate and the holding plate.
• brackets with stiffeners have the disadvantage of creating an air pocket between the wall and said insulating panel. Indeed, during racking, the latter does not operate sufficiently so that the air between the insulating panel and the wall can evacuate.
• This air pocket causes the appearance of a deformed area on the outside of the insulating panel, deformed area that will be visible and therefore unsightly and that may complicate the installation of an additional structure type plasterboard.
• the present invention therefore proposes to solve these disadvantages by providing a bracket for the mounting of insulating panels for better insertion of the insulator P against the wall M.
• the invention relates to a bracket for laying an insulating panel on a wall of a wall comprising a fixing plate attached to said wall and a holding plate, said holding plate extending substantially perpendicular to said fixing plate for holding said insulating panel, characterized in that said bracket comprises reinforcing means arranged between the fixing plate and the holding plate for stiffening said bracket, said reinforcing means comprising means for notching the panel insulating.
• This invention advantageously provides a bracket provided with means for locally deteriorating the insulating material of the panel to facilitate racking. Indeed, by notching the insulating material which is generally a fibrous material, it facilitates the racking and evacuation of air stuck between said wall and said insulating panel.
• said reinforcement means comprise at least one stiffener, in particular a blade, arranged longitudinally with respect to the fixing plate and to the holding plate, the stiffener having an edge from which the notching means extend.

• the reinforcing means 103 are blades 1030 having a substantially triangular shape that is to say comprising three sides or edges 1031. Two of these sides are in contact with the holding plate 102 and the attachment plate 101 to provide said blade with a stiffness-enhancing effect.
• the notching means 104 are thus arranged on the third side of the blade forming the stiffener 1030.
• These notching means 104 can be in different forms.
• the notching means 104 comprise a toothing 1040 comprising a plurality of teeth 1040a arranged on the edge 1031 of the stiffener forming the hypotenuse.
• This plurality of teeth 1040a is used to incise the insulating panel P.
• the plurality of teeth 1040a comes into contact with the fibrous material constituting said insulating panel, the teeth 1040a incising the fibers of said insulating panel P. This fiber incision facilitates racking by locally reducing the resistance of the panel P.
• this local incision of the insulating panel P reduces the effect of air pocket created during racking by allowing the air between the panel and the wall to be at least partially evacuated.
• These teeth 1040a can have different shapes.
• these teeth have a triangular shape of any type or isosceles or equilateral or rectangle or any shape to have an incision function.
• the dimensions and number of teeth 1040a is variable, preferably the teeth 1040a will have a width at most equal to 5mm, 4mm, 3mm and preferably at most 2mm.
• the teeth 1040a can be evenly distributed over the hypotenuse of the stiffener or have a different density of teeth 1040a.
• the notching means 104 comprise at least one tip 1041.
• This tip 1041 is used to perforate the insulating panel P.
• This tip 1041 is then arranged to protrude and extend in a direction perpendicular to the wall of said wall.

• This third embodiment advantageously makes it possible to combine the effects of the two previous modes of execution by having a stiffener which will perforate the insulating material with one or both of its points and then shear it with said teeth.
• the hypotenuse of the stiffener 1030 may be rectilinear or curved, the curvature may be concave or convex.
• the rectilinear or convex hypotenuse it will be preferred to have the rectilinear or convex hypotenuse whereas in the second embodiment, a concave hypotenuse is preferred.
