Abstract
A floor composed of a plurality of modular elements comprises a first subassembly consisting of a base component and a first intermediate element and a second subassembly consisting of a second intermediate element and a top component forming a point elastic floor. The two subassemblies are secured together by connecting means with an angular orientation offset such as to define the contact surfaces and allow assembly by interlocking. The intermediate elements are disposed with a median honeycomb structure sandwiched between two stiffening plates of the same format and dimension. The plates are of nonwoven material and have reinforcement and stiffening disposed in a canvass of warp and weft threads.
