Description

COUPLING PART AND PREFABRICATED CONSTRUCTION KIT

INCLUDING THE COUPLING PART

The present invention relates to the field of constructions, preferably prefabricated constructions, more particularly wooden frame constructions. This technique of construction using prefabricated elements is more and more popular nowadays because it saves precious time.

In the context of the present invention, the construction, preferably prefabricated, is understood to mean all types of elements which practically only need to be assembled on site, the elements being prefabricated in the factory.

Without however being absolutely limited thereto, the present invention will be described in the context of dwellings e † timber frame constructions. In this type of construction, provision is generally made for the use of beams or planks forming the framework e † of bracing elements which may be formed from laminated panels. Usually, each wall section is made up of a series of panels comprising a herringbone frame joined to each other and provided with some internal reinforcements. On the other side of the frame there are con † reven † emen † s, for example laminated panels (OSB type). Between the panels, within the frame, we generally introduce an insulating material, such as cellulose wadding, wood fiber to another equivalent insulating material which then fills † the space between the rafters, the reinforcements and the con † reven † emen † s formed from laminated panels. One of the great advantages of this construction technique is the realization in factories of sections of walls of small and great length and of variable thickness which arrive on site already assembled, requiring only to be assembled to form the closed shell. construction.

Such panels can make a house from the ground up to the faith †. The house can be built on stilts, foundation walls or on pedestals.

On such panels, the exterior siding is then placed as well as the interior finish.

Unfortunately, such constructions, preferably prefabricated, still have many drawbacks in terms of thermo-acoustic insulation, in particular in the floor elements, of taking up the load in the wind, of the distribution of load descent but also in terms of thermal inertia.

The invention has for bu † to overcome the drawbacks of the state of the art by providing a coupling part making it possible to improve the thermo-acoustic insulation of the floor elements, the thermal inertia of the construction, the recovery of the wind load e † of the load descent distribution.

To solve this problem, there is provided according to the invention a coupling part between an element of horizontal orientation e † an element of vertical orientation for construction, preferably for prefabricated construction comprising a first seat rail arranged to rest. on a ridge of a vertically oriented element such as a wall ridge, a foundation stud ridge or a pile ridge, a second upper rail, substantially parallel to the first foundation rail e † separated from the first seat rail by at least one spacer, said at least one spacer occupying a volume or a surface on said first seat rail respectively less than the lower volume formed between the first and the second rail or lower than the surface of the first seat rail, said first rail seat, said second rail delimiting a reception area arranged to accommodate a reinforcing material e † cooperating with a horizontal orientation element comprising at least one support wall, a formwork, a granule e † a binder.

As can be seen, the coupling piece according to the present invention presents a par † ease of assembly by providing a reception area for floor elements, which is also intended to contain the granula † e † the binder present in the horizontally oriented element.

In this way, according to the present invention, when the structural elements of the floor are placed in place, a granula † with a binder is poured over the structural elements of the floor and this flows between the structural elements in all the floors. interstices, but also in the reception area. Such granules, for example, concrete, cement, expanded clay balls, recycled granulated materials. The binder is for example a cement, lime, a polymer, a resin, ...

As we can see, the presence of this reception area in which the horizontal orientation element is introduced, directly or through an additional connection piece, also makes it possible to accommodate the granula † mixture. e † binder e † thus results in a set of substantially joined vertical e † horizontal elements which cooperate together. In this way, the rigidity of the construction is improved, but also, by the increase in the weight of the construction, thermal inertia is improved as well as the recovery of the load in the wind and the distribution of load descent.

Advantageously, said at least one spacer is pierced with at least one orifice arranged to allow the passage of at least one reinforcing bar or of said reinforcing material.

In this way the reinforcing material or the rebar reinforces the cooperation between horizontally oriented elements and vertically oriented elements and improves the rigidity of the construction.

In a preferred embodiment, the coupling piece according to the present invention comprises a series of spacers spaced apart from each other, for example regularly, which increases the volume of the reception area and its capacity to accommodate the aggregate and the binder.

In a particular embodiment of the present invention, said at least one spacer is a tubular spacer of square or rectangular section, comprising four parallel walls two by two and interconnected by their lateral ridges forming a recess, said four walls forming said tubular spacer of square or rectangular section, said spacer being positioned such that a first wall of the spacer rests against an upper face of the first seat rail and the second wall of the spacer, parallel to the first wall , rests against a lower face of the second upper rail.

In a preferred form of the coupling part according to the present invention, at least two spacers are present, arranged so that the recesses of each of the spacers face each other, said recesses then being arranged to accommodate at least one rebar or said reinforcing material to thereby form a chain. Advantageously, according to the present invention, said spacer is made of metal, for example steel, preferably stainless steel, carbon, polymer material with or without a reinforcing structure such as a fiberglass structure.
