Problems solved by technology

So when the plate is assembled on the support, a large part of the bolt shank is unconstrained and causes stress on the insert 7
The stresses exerted on the insert 7 may weaken the core of the sandwich structure, which may lead to severe damage to the mechanical properties of the panels

Embodiment Construction

[0023] [twenty three] figure 2 Shown is a floor panel body for a passenger transportation vehicle according to an embodiment of the present invention. The floor panel 10 comprises a central sandwich structure comprising at least two walls 11 , 12 respectively located on opposite outer surfaces of a honeycomb core 13 .

[0024] [24] These walls 11, 12 are some fibrous skeletons. Fibers can be selected in the group given by way of non-limitation: carbon fibers, graphite fibers, glass fibers, silica fibers, silicon carbide fibers, or have the required Any other fiber that is defined in relation to light weight.

[0025] [25] The honeycomb core 13 is formed of, for example, aramide. Aramid fibers actually have low flammability, great fracture resistance and high modulus of elasticity.

[0026] [26] A floor covering 14 such as a carpet is positioned on the floor panel body 10 . The covering 14 serves to protect the floor panel 10 against movement-related erosion or other erosi...

Abstract

The invention concerns a device for fixing a lightweight panel on a support. Said device comprises an insert (18) including at least one flange (20), said insert being designed to receive a bolt-type fixing member (16). The invention is characterized in that said flange (20) has an outer surface comprising tooth elements (23) and the device comprises a part made of ductile material (24) including an opening for passing through the fixing member (16). The tooth elements (23) are designed to co-operate, when the panel is being fixed on the support, with the ductile part (24) to enable said panel to be fixed without deforming it.

Description

technical field [0001] [01] The present invention relates to a fastening device for fastening lightweight panels, such as sandwich construction panels, to supports. Another object of the invention is a passenger transport, such as an aircraft, comprising such a fastening device. Background technique [0002] [02] Sandwich structures of composite materials have some properties, especially mechanical ones, especially for the smallest mass. These structures are therefore used extensively in the aviation industry (doors, floors, wing leading edges, ailerons, inner bulkheads, etc.). [0003] [03] FIG. 1 schematically shows a partial sectional view of a prior art cabin floor. The floor panel is composed of a floor panel body 1 of sandwich structure. Each panel 1 comprises at least two walls 2 , 3 situated respectively on opposite outer surfaces of a honeycomb core 4 . These plate bodies 1 have a small thickness, generally about 10mm, and said plate bodies 1 are fixed on the si...
