Prefabricated finished floor element, method for manufacturing a floor and floor obtained

Patent number: FR3127239
Date of publication: 2023-03-24

The invention relates to a prefabricated finished floor element (1), consisting of a panel made of a structural material (MS), comprising in its thickness erecting blocks (5) and reinforcements (6, 7), and at least one upper layer (14) made of structural materials. The raising blocks (5) form a grid and define between them a network of ribs (8, 9) extending in two intersecting directions (X, Y). The reinforcements (6, 7) are arranged in two parallel layers (10, 11) on either side of the raising blocks (5). They project from the edges (4) of the floor element (1) in order to ensure mechanical continuity with adjacent floor elements (1). A floor (20) is obtained by juxtaposing floor elements (1) separated from each other by a junction zone (ZJ) delimited by an integrated formwork spoiler (12), and by casting only in the junction zones (ZJ) a keying material (MC) with very high performance, in order to seal the said floor elements (1) together and to the load-bearing elements of a building, making it possible to produce a load-bearing structure for a building without a compression slab cast on site.

Wood-concrete composite floor having a planar wood element, method for production of same, and constructions having such a wood-concrete composite floor

Patent number: WO2023/062238
Date of publication: 2023-04-20
Inventors : KÜNDIG, Christian, KREIS, Benjamin, KÜBLER, Wolfram

The invention relates to a wood-concrete composite floor having a planar wood element, by means of which spans can be achieved with little dependence on the relative inherent weight of the floor. The floor layer construction includes a wood layer, an insulating layer and a concrete layer (4). In one embodiment, the layer construction is interrupted by at least one bearing means (8), in that this bearing means traverses at least the concrete layer (4) and the insulating layer and extends downwards at least as far as the wood layer. This internal bearing means (8) can also be created in variants which project out of the composite layers. In a different embodiment, for a high level of soundproofing the floor comprises in its insulating layer two insulating materials of different densities, wherein the denser insulating material rests directly on the wood layer, and this is intended to act as a vibration damping means. In a further embodiment, the wood panels of the wood-concrete composite floor that form the planar wood element are pressed together in order to convey tensile forces therethrough. According to the invention, the efficiency during the production of wood-concrete composite floors having large spanned dimensions can be significantly increased.

Temporary walkway system with modular tiles interlocking in three-dimensions

Patent number: WO2023/034261
Date of publication: 2023-03-09

A modular tile for a walkway system interlocks with another tile to constrain movement of the interlocked tiles in all three-dimensions. The tile includes a male projection which may be tapered to provide lateral wings that are received in corresponding pockets of a female receiver of the other tile. The wings may include vertically-facing male stop surfaces that are engageable with vertically-facing female stop surfaces within the pockets. The male projection may further include a forwardly protruding ridge that is received in a corresponding groove of the female receiver of the other tile. The engagement of the stop surfaces of the wings and pockets, and the engagement of the ridge in the groove is such that the tiles are vertically interlocked with each other. The tiles may be configured to enable a pivotable interlocking connection while one tile remains on the ground.

A carpet to recover kinetic energy and a method for utilizing this energy

Patent number: WO2023/025977
Date of publication: 2023-02-27
Applicant(s): JPTUF

The object of the invention is a carpet (10) to recover kinetic energy and if consists of at least one air cell (1 ) that has been set to compress when a load (K) affects it and to restore its original shape when the load ceases, at least one transfer channel (2), at least one over pressure valve (3) between each air cell (1) and some transfer channel (2) that has been set to release over pressure from the mentioned air cell into the mentioned transfer channel when the carpet 10 is loaded with a load (K) and the inside volume (V) of the air cell (1 ) gets smaller as the shape of the air cell changes by the effect of the mentioned load, at least one under pressure valve (4) located in each air cell ( 1 ) that has been set to let air into the under pressure state set air cell when the effect of the load (K) to the air cell (1) ceases or reduces and the inside volume (V) of the air cell expands or tends to expand in order to restore its original shape, and the transfer channel 2 of the carpet 10 has been connected directly or by a continuation channel 6 to a turbine (T) or other apparatus that uses air flow to utilize air flow (f, F).
