Description

The present invention relates to the field of the realization of construction works, in the general sense, made from modular elements assembled dry.

The invention relates, more particularly, to a modular building element whose stacking, in dry bunk beds, allows the realization of construction works, particularly of the type of protection, insulation, decoration and, mainly , support.

The object of the invention finds a particularly advantageous application for producing, as a construction work, vegetated or not, a wall, a wall, an embankment, a dike, a solid mass, etc.

The prior art has proposed many embodiments of modular building elements, made from different materials, such as reinforced concrete or not, or solid wood or reconstituted.

Modular wooden building elements have the advantage of being natural by blending particularly well in the landscape. For example it is known, by the patent EP 1 252 398 , to produce a work from crafted wooden planks, forming facades of facades placed end to end and extending at a distance and parallel to bottom rails also end to end. The longitudinal members are mounted on spacers spaced apart from each other and having notches for maintaining the longitudinal members. The longitudinal members extend in bunk beds between each of which is interposed a bed of spacers. The internal volume, delimited between the longitudinal members and the spacers, is filled by stones or rock, in order to constitute the construction work.

It must first of all be considered that the woodwork elements have a relatively high cost, given their particular shape to ensure their assembly. In addition, their implementation is relatively difficult to carry out and requires particularly careful preparation of the land on which they are arranged. Finally, the realization of a structure with these prefabricated elements requires a relatively long time, incompatible with the essential constraint, namely the speed of setting up a retaining structure, especially along a traffic lane.

He is also known by the patent application FR 2 751 005 , a device for stabilizing the erosion of a plant support comprising two parallel rails spaced from each other and two parallel crosspieces and spaced apart from one another by being joined to the rails by rods, such as described in the preamble of claim 1.

The object of the invention is therefore to remedy the various disadvantages of the state of the art by proposing a set of modular building elements adapted to be of simple design, while being able to be implemented easily and quickly.

Another object of the invention is to provide a set of modular building elements having a certain aesthetic effect, while having a relatively limited weight for handling, without the use of handling equipment.

To achieve such an objective, the object of the invention relates to a set of modular elements for the realization of a structure according to claim 1.

According to an advantageous characteristic of realization, the abutment means comprise means of adjustment of their positioning along the logs of base.

According to a preferred embodiment, the abutment means are constituted by a log supported by the top of the seat logs extending substantially parallel to the front and bottom logs, assembly means being provided between the log of abutment and the logs.

Advantageously, the assembly means, between the abutment log and the seat logs, are common with the assembly means between the bottom log and the seat logs.

To allow the structure to be given a direction of non-linear extension, the bottom log has a length less than the front log, so as to extend recessed with respect to each end of the log face.

Preferably, each extreme transverse fascia of the facade log has a beveled portion.

According to a preferred embodiment, the front and bottom logs extend substantially perpendicular to the logs.

By way of example, the logs each have a diameter of between 6 and 60 cm and preferably between 15 and 35 cm, while the front and bottom logs have a length of between 0.6 and 4. m and, preferably, between 0.8 and 2 m and the seat log a length of between 0.4 and 2 m and preferably between 0.8 and 1.5 m.

Advantageously, the logs are solid wood, raw or reconstituted.

Another object of the invention is to propose a structure comprising a stack of at least two superposed beds of sets of modular building elements conforming as described above, the lower bed comprising at least two modular building elements of which the front logs are placed end to end, while the upper bed comprises at least one modular building element whose bottom log bears against at least one support log of the lower bed.

As more specifically Fig. 1 to 3 The object of the invention relates to a set of modular building elements 1 for producing a structure 2 in the general sense. In the exemplary embodiment illustrated, the modular building element 1 comprises at least one facade log 3 and a bottom log 4 extending at a distance from one another and substantially parallel. The modular building element 1 also comprises at least two and, in the illustrated example, two sill logs 6 each supported by the top of the facade log 3 and the top of the bottom log 4, in turn. extending at a distance from each other. In the exemplary embodiment illustrated, the two seatbars 6 extend substantially parallel to each other and substantially perpendicularly to the front and bottom logs 3 and 4.

It must be considered that the log front 3 and bottom 4 extend to a lower level with respect to the extension plane of the seat 6. Advantageously logs, each log 3, 4, 6 has a cross section substantially circular. Preferentially, each log 3, 4, 6 is made of solid or reconstituted wood. Preferably, each log 3, 4, 6 is made of solid wood, squared or not to the desired diameter.

The front wall 3 has a diameter substantially equal to the bottom log 4. Similarly, the two seat logs 6 have substantially identical diameters. More preferably, the diameter of the seat logs 6 is substantially identical to the diameter of the front and bottom logs 3 and 4.

Of course, it may be contemplated that the diameter of the seat 6 log has a different value of the diameter of front 3 logs of background and 4. Similarly, it is clear that the cross section of the log 3, 4 , 6 can be different to that comparable to a disk. Thus, the cross section of the logs 3, 4, 6 can be, for example polygonal.

By way of example, the logs 3, 4, 6 each have a diameter of between 6 and 60 cm and preferably between 15 and 35 cm. The facade log 3 or the bottom log 4 has a length of between 0.6 and 4 m, and preferably between 0.8 and 2 m. The seat ring 6 has a length of between 0.4 and 2m and preferably between 0.8 and 1.5m.

The modular building element 1 also comprises means 8 for connection between each seat log 6 and log each front 3 and bottom 4. These connecting means 8 are of any type known per se, to ensure an effective connection between the front 3 and bottom of the logs 4 and the foundation logs 6 extending to the upper level. For example, these assembly means are constituted by lag bolts, dowels, rebars or screws.

According to another characteristic of the subject of the invention, the modular building element 1 comprises stop means 10 for a bottom log 4 ₁ of a similar building element 1 ₁ superimposed to be placed on the logs 6. Thus, as Figures 4 to 7 , The stop means 10 enable to ensure blocking of the analogous construction element, mounted in superimposed manner so that the bottom of log 4 ₁ is located on the back abutment means 10 in consideration of before the element 1 formed by the front wall 3. The stop means 10 block the displacement of the superimposed building element 1 ₁ in the direction of the bottom log 4 - front wall 3, represented by the arrow f ₁ . In the embodiment shown in the drawings, the abutment means 10 consist of a log supported by the top of the seat logs 6 extending substantially parallel to the front and bottom logs 3 and 4.

Joining means 13 are provided between the stop log 10 and the seat logs 6. These connecting means 13 are identical or different from the assembly means 8.

Advantageously, the abutment log 10 extends plumb or substantially superimposed on the bottom log 4. In this embodiment, it may be advantageous if the assembly means 13 and the assembly means 8 are common. In other words, the bottom log 4 is assembled to the seat ring 6 and the stop log 10 by means of assembly means 8, 13 common. For example, these assembly means 8, 13 may be constituted by means of a lag bolt, as illustrated in FIG. Fig. 3 .

According to another variant embodiment, it should be noted that the stop log 10 can comprise means for adjusting its positioning along the logs. seat 6. In other words, the abutment stub 10 can be adjusted in depth relative to the log facade 3, so as to adjust the result of the work to be performed. In this embodiment, the assembly means 13 of the stop log 10 may have a removable or dismountable character, making it possible to modify its positioning with respect to the facade log 3. It may thus be provided to pre-drill the along the logs 6 corresponding to different possible positions of the stop log 10.

Of course, the abutment means 10 may be made differently to a single log. For example, the abutment means 10 may be made by two separate elements fixed on the seat bars 6 or on the bottom log 4.

According to an advantageous embodiment, it should be noted that the bottom log 4 has a shorter length compared to the front log 3, so as to extend back from each of the ends of the front wall 3. Tel that this is more accurately apparent from the Fig. 2 it can be provided that the front wall 3 protrudes from each side with respect to each seat log 6, while the bottom log 4 and the stop log 10 extend substantially to each log seat 6. This arrangement makes it possible to place two side by side building elements 1 with an angular offset between them. In other words, according to this variant, the facade logs 3 of two building elements side by side are not aligned.

According to a preferred embodiment, each end of the front wall 3 comprises a beveled portion 15 allowing the end-to-end logs 3 to come into contact when two modular building elements are placed side by side with a relative angle between them.

Each modular building element 1 adapted to the realization of an assembly according to the invention therefore constitutes a relatively simple construction element, which can be implemented relatively easily. Thus, for example, a structure of 20 m ² was produced in one hour using 300 modular building elements according to the invention.

In order to produce a construction structure 2, it is advisable, after the construction of a site, to place the construction elements 1 side by side, by putting the facade logs 3 in alignment with an alignment offset or not, which is function of the form to give to the work. It thus constitutes a first bed above which can be placed a second bed of modular building elements 1 ₁ forming an assembly according to the invention, placed so that each bottom log 4 ₁ abuts or abuts against a support log 10 of a modular building element forming part of the lower bed. The positioning of the building elements 1 ₁ is simple since it is reduced to placing the bottom logs 4 ₁ behind the stop logs 10 of the lower bed in a direction of extension substantially parallel to the bottom logs 4 of the lower bed. Each modular building element 1 ₁ of the upper bed is therefore directly placed in position and locked relative to the lower bed.

The modular building elements 1 ₁ are mounted in staggered rows or superimposed with respect to the modular building elements of the lower bed. The spaces, delimited between the elements of construction, are filled with earth, stones or rocks, as and when the construction, preferably, of each bed. Modular building element beds 1 ₁ are thus made to a height adapted to build the structure 2.

It should be noted that the construction elements 1 of the lower bed can be blocked or anchored to the ground by any appropriate means, given the work to be done. In the same direction, it should be noted that the staggered assembly of the modular building elements 1 _i in the different beds ( Fig. 5 ) makes it possible to secure the elements together to strengthen the stability of the structure.

In the foregoing description, the modular building element comprises two seat logs 6. Of course, it may be provided that the modular building element comprises a larger number of seat logs 6.
