Description

WOOD BUILDING BRICK WITH PLASTIC SEALS

BOOTS Object of the invention

The present invention relates to the field of construction and building and in particular to that of bricks or building blocks one (s) on the other by means of joints to form walls, walls or partitions.

State of the art

In the field of construction, and in particular in the field of walls and partitions, there is a large number of devices that are conventional such as building blocks, partitions formed of metal profiles coated plasterboard , or even concrete walls poured in situ.

In the particular case of building blocks made of hard and porous materials, the blocks are stacked staggered and secured by a binder type glue or mortar. These blocks may have grooves and tongues so as to be nested, or other nesting geometries. However, these prefabricated elements generally offer only approximate nesting systems. Another disadvantage of this type of wall is that the assembly requires some professional experience and that the finish is obtained after implementation of several techniques (coating, grouting, painting, etc.). In addition, the waste is bulky, dusty and scarcely recyclable.

As regards the partitions formed of metal profiles and plasterboard, their assembly also requires some experience or execution necessarily performed by a trade. On the other hand, the necessary equipment is bulky and varied (long sections, screws, precision measuring tools, various tools, etc.).

Poured concrete walls are expensive and require the same execution by a trade. This type of partition is assembled with a specific material in a particular order of execution and with a respect of the techniques of implementation (stability, alignment, preparation of the formwork, drying time, etc.).

Other methods have also emerged to overcome the disadvantages of "conventional" methods, as listed above.

WO 2006/024061 A1 discloses a wood brick for mounting walls, comprising, on one side a set of projections and on the opposite side, a set of corresponding recesses for receiving the projections. In this way, the bricks are stacked and held together by driving the projections of one brick into the recesses of the adjacent brick.

[0008] EP 0 744 507 A1 discloses a modular brick, which can be assembled by interlocking. The module comprises two parallel plates, preferably made of wood, or possibly plaster or composite material, interconnected by several parallel intermediate elements. The intermediate elements have, on two opposite ends of the brick, a set of lateral projections and alternate hollow cavities. In this way, when two modules are superimposed, the projections of one module project into the hollow cavities of the other module, forming a connection by interlocking.

The document FR 3 013 063 A1 discloses a hinged wooden hollow block for the realization of walls for the construction of wooden constructions. The block is made using a molding process or an assembly of machined wood panels. The low weight and volume occupied by a block of wood nestable before assembly allow a lighter packaging and easier transportation than those of traditional concrete blocks, heavy and bulky. Hollow and closed design cinderblock allows filling with an insulating material of choice, introduced through two holes located on the top of the block.

Document DE 2 139 967 describes a prefabricated wooden element, which can be fitted to construct building partitions.

EP 2 966 235 discloses a building block for forming a wall construction, which building block comprises an insulating material and vertical bearing walls extending from one longitudinal side to another longitudinal side of the building. construction block, wherein the insulating material is provided with recesses for receiving the load-bearing walls to hold them in place, wherein an inner part of the insulating material and the load-bearing walls are provided with recesses for receiving at least one longitudinal reinforcement connecting the carrier walls to each other in the longitudinal direction of the building block to form an inner core where the vertical carrier walls, the insulating material and the reinforcing member together form the base load bearing capacity in the building block, and said building block comprising at least one outer core formed by parts of mat riau insulating and supporting walls on the outside of the reinforcing member, the outer core having consolidation and reinforcement properties to the inner core.

Goals of the invention

The present invention aims to provide a solution to improve the performance of bricks or interlocking wood blocks for the formation of walls and partitions, in particular through an improvement of the interlocking elements.

Another object of the invention is to provide a reusable brick, with nesting elements resistant in time and robust despite several successive interlocking / disengagement.

Another object of the invention is to provide a product ready for use, manuportable, and can be used directly to mount a partition by anyone without any professional training. Another object still pursued by the invention is to provide an environmentally friendly device, with a final appearance not requiring additional finishing such as coating, capping, etc.

Another object of the invention is to provide a quick, easy, accurate and mortar-free casing system allowing a user to mount and dismount a brick wall or blocks easily in a series of virtually unlimited applications. (Interior housing, balustrades, railings, floors, stairs, fitting rooms, cube cube, furniture, partition walls, open-space offices, storage, wall insulation, floor insulation, etc. .)

Description of a preferred embodiment of the invention

One embodiment of the composite brick 1 recommended by the present invention is shown in Figures 1 and 2. The composite brick has, in use, a lower face 9 and an upper face 10.

The composite brick 1 consists of a main body of wood or wood chipboard 2 and assembling joints of plastic (plastic) 3 located respectively at the lower face 9 and top 10 of the brick 1.

For wood or wood chip, for example, and in a non-exhaustive manner, all solid wood panels mono- or multilayer, glulam boards, plywood, particle board, such as laminate, melamine, panels thin oriented strips or OSB, or fiber boards, for example medium density or MDF.

By plastic or plastic, it is understood any type of plastic containing a polymeric base material. For example, seals will be injected seals made of thermoplastic polymer, preferably ABS plastic, or, preferably, injected seals made of biodegradable thermoplastic polymer, such as plastic PLA.

The main body 2 is preferably composed of four lateral faces 6 and a lower face 6A in the form of wooden plates assembled so as to form a rectangular parallelepiped (possibly hollow for the provision of an insulator), as shown in FIG. the figures. The presence of a bottom in the main body allows a better distribution of the insulation (which otherwise would tend to crash into the bottom of the wall by gravity). These side faces 6 and 6A can be assembled using glue or other fastening means such as screws and / or pins. The assembly of the lateral faces 6 and 6A of wood is preferably made mechanically by applying glue and fixing the plates by compression. The cutting and drilling of wood is done by precision machines in a digital machine work center.

The plastic assembly joints 3 are fixed on the main body 2, for example using glue and / or screw 7. The joints 3 are located to form the assembly sections of the faces lower 9 and upper 10 of the composite brick 1. As illustrated in the figures, these seals

3 form a thin frame whose geometry coincides with that of the upper 10 and lower surfaces 9 of the main body 2 (substantially the same geometry and the same dimensions). These plastic frames 3 are preferably made in one piece, and manufactured by plastic injection in custom molds.

The plastic assembly joints 3 comprise interlocking elements 4 and 5 for assembling the bricks 1 between them to form a wall or a partition. The interlocking elements of the seals 3 cooperate by elastic interlocking, thanks to a male part 4, or projecting, and a female part 5, or recessed. The male part of the interlocking elements

4 is on the joint of one of the faces of the brick 1 (lower face 9 or upper 10), while the female part of the interlocking elements 4 is on the joint of the other face of the brick 1 . In this way, the bricks can be assembled together, by fitting the joints of their face lower and upper, so as to form with the adjacent bricks an assembled wall as shown in Figure 3.

An example of a male part 4 is shown in FIG. 4 while an example of a female part 5 is shown in FIG. 5. In the case illustrated, the shape of the elements of the male part 4 are projecting, substantially in the shape of a cross. The elements of the female part 5 are recessed and delimited by protruding elements substantially in octagon (or cylinder, not shown). The geometry of the interlocking elements according to the invention is however not limited to this particular configuration.

In a preferred embodiment, the brick of the present invention comprises an insulating filling material 8 located in the hollow formed by the side faces 6 and the lower face 6A of the wooden body 2. The insulating material 8 is integrated mechanically or manually in the production line.

The dimensions of the composite bricks 1 are adaptable to meet specific mechanical requirements and materials used vary depending on the final partition to achieve (smooth, waterproof, flame retardant, etc.). The quality of the wood can be specific, as well as the type of insulation (thermal and / or acoustic). The minimum dimensions of the bricks are determined by the thickness of the wood and / or by the need to have an industrial type of realization for the joints which must have at least 2 frictional contact points at the interlocking crosses.

According to an advantageous embodiment of the invention, and for optimum stability, the assemblies of composite bricks according to the present invention are assembled and screwed on a wooden structure or a fixed U-shaped metal rail or profile and / or stuck to the floor, wall and / or ceiling of dwellings or buildings, such as on a rafter or a guide of width equal to or greater than the width of the wooden brick. Before fixing the rafter or guide, it is best to take the precaution of attaching an expansion joint to the floor, wall and / or ceiling. Then, the partition is mounted, like a construction game, taking the precaution of staggering the wood bricks during assembly for greater stability (staggered mounting). The implementation of the present invention is easy: its fast nesting system, easy, accurate and without the use of mortar allows the user to mount and dismount the object of the present invention as a building set with virtually unlimited applications (interior interiors, balustrades, railings, cube cube, floors, stairs, fitting rooms, furniture, partition walls, open-space offices, storage space, insulation walls, floor insulation, etc.).

The implementation by interlocking composite bricks

1 provides a partition with uniform, precise, tight, straight joints, which are automatically formed by simple assembly and without bulky tools to achieve them and without drying time required. In the same way, it will be easy to dress these bricks with plates (plasters, terra cotta, stones, plastics, etc.) and this, by simple screwing or gluing according to the desired final aspect.

This composite brick 1 allows the construction of temporary partitions, removable and easy to reassemble thanks to the strength of the plastic seals 3. These partitions can become permanent and permanent by applying, on the surfaces in contact with said frames, a glue specific to the fastening properties suitable for plastics. Users will be able to create modular partition walls, fixed or removable in their homes or business premises to create additional living or working spaces, or storage, without using a building trades or construction.

Examples of possible industrial applications:

- easy assembly (and disassembly) of stands at trade shows, exhibitions, festivals, etc. ;

- doubling and covering commercial surface walls with personalized final appearance;

- creation of furniture (offices, storage furniture, modular shelves, fitting room, etc.);

- partitions, walls and dividing walls in industrial spaces, staircases. This manufacturing process provides ecological and economic benefits. The object of the present invention is resistant, waterproof, insulating, environmentally friendly and aesthetic with a convenient packaging and safe for health.
