Definitions
- the field of the invention is that of building and construction.
- the invention relates to a building system of ecological buildings and high energy performance, for example individual houses of wood.
- the Grenelle de l'Environstitution has played a leading role in changing the construction models in an effort to save energy.
- each frame element is drawn using a software that controls a cutting machine elements.
- Framing elements are cut and assembled in the workshop according to plans provided by the design office to form walls / panels which are then insulated and barded. The finished walls / panels are then transported to the site where they are mounted together by means of lifting equipment.
- An advantage of this construction technique is that it allows the assembly workshop prefabricated elements sheltered from the weather and requires little labor on site. In addition, the construction time is reduced compared to the conventional construction method mentioned above.
- a three-dimensional, self-supporting structure is described in the patent application FR 2,906,278 in the name of the Applicant.
- This structure consists of perpendicular horizontal and vertical walls, each wall consisting of spaced parallel elements which intersect with the parallel elements of the other walls. The intersections of these walls are sufficient for maintain them while allowing their relative movements allowing the realization of transformable volumes.
- this structure is more suited to the design of non-isolated buildings, such as garden sheds, or for summer occupation.
- the invention particularly aims to overcome these disadvantages of the prior art.
- an object of the invention is to provide a construction system allowing, from elements of small section, a simple, robust and fast assembly of an isolated building structure, on any type of terrain.
- Another object of the invention is to implement a building structure that requires little or no external and internal finishes, and therefore reduces labor and production costs.
- Yet another object of the invention is to use walls, floors and roofs to form a building structure adapted to different climates (weather resistant and in particular waterproof) and which has improved thermal and acoustic properties. .
- the invention is based on a completely new and inventive approach to a construction system of a building that consists of erecting a regular and closely spaced frame, of intertwined structural elements to form a structure carrier and the walls of a building.
- These structural elements may be chevrons.
- a first framework called the supporting framework
- a second framework referred to as an internal framework
- a third framework called external framework
- the second and third frames form envelope frames which each consist of several half-walls.
- the walls of the building (walls, ceiling, floor) therefore consist of an inner semi-wall and an outer semi-wall.
- the structural elements of the internal framework intersect with other structural elements of the internal framework and with the structural elements of the supporting framework.
- the structural elements of the external framework intersect with other structural elements of the external framework and with the structural elements of the supporting framework. In fact, by attaching to the supporting frame, the inner and outer frames are interconnected.
- interlocking means in the context of the invention that the parallel elements of an envelope frame interlock or entangle with other elements of the same framework and the supporting framework (or even the other framework of envelope).
- said uprights or posts and said sleepers or beams of the supporting framework consist of rafters, of wood for example, associated with at least one bracing plate, plywood for example.
- the constructive system of a structure of the invention does not require a particular connection system between the walls and the roof, between the walls and the floor, or between the walls between them. Indeed, the numerous contacts generated by the respect of the weft, the intercrossing of the elements of a semi-wall with the elements of another semi-wall, or with those of the supporting structure ensure a rigidity and a stability of the erected structure.
- the construction system of the invention consists of elements or structural parts which are intended to be connected and assembled to form a three-dimensional self-supporting structure, and therefore do not require the implementation of a traditional primary structure structure (including elements of large section, including posts and beams) and complex connectors (only the screws are necessary to bind the elements of the structure of the invention), even if n It is not excluded that such elements are used in a complementary way.
- these elements are intended to form the supporting frame and the internal and external frames of a building, the space between the inner and outer frames may constitute a formwork.
- the frame is such that the spacing between the elements is equal to the section of the elements (in the case where the elements are of square section), or to one of the dimensions of the section of the elements (in the case where the elements are of rectangular section).
- the system of the invention is intended for the construction of variable surface buildings, removable and for various uses.
- the system of the invention also allows the assembly of transportable modules that can be assembled together on the site.
- These prefabricated structural elements are for example in the form of blades or rafters of wood (or reconstituted wood), glulam, or metal profiles, of substantially rectangular section (or square, or other) which play a structural role and a role of interior and exterior finishing.
- Such a freestanding structure does not require foundations and can be erected on any type of terrain (steep slope, above the water by means of piles as shown in the diagram). figure 17 ), the structure can be detached from the ground or not, or anchored in the ground.
- these structural elements constitute an envelope, the connections between the walls between them, with the roof and the floor having sufficient rigidity due to the many crossings and contacts between the structural elements.
- An insulator can be blown between the inner and outer face of the formwork.
- the constituent elements of the envelope structure play a role of interior and exterior facing. Such a solution requires little or no finishing, and therefore reduces the costs of implementation.
- At least one of said half walls of said inner frame further comprises at least one bracing panel.
- bracing panel is, for example, derived from wood (particle board, plywood) and can play a role of vapor barrier.
- a bracing panel may be made of glass, or polycarbonate, or other, and will then have a more limited bracing role.
- At least one of said half-walls of said outer frame further comprises at least one bracing and / or sealing panel, which may in some cases be translucent and then made of glass, or polycarbonate, or other material able to let in light.
- rain guards can be added between the rafters and bracing panels to which the rafters are attached.
- an insulator is inserted into said formwork.
- thermal insulation is inserted between the bracing panels on which structural seams or inner and outer rafters are fixed.
- insulating boards or straw bales are inserted in the formwork.
- the insulation will be constituted by a bulk material, which may in some cases be blown into the formwork, the use of bulk material being particularly advantageous since it avoids any cutting operation for a adaptation to the dimensions of the formwork naturally delimited between the envelopes.
- Such a bulk material may be cellulose wadding, glass wool, sheep wool, wood chips, or more specifically cork.
- a self-supporting structure will include a bracing panel supporting rafters parallel to each other and forming an internal face of a floor, the interstices between said rafters being then filled so as to ensure continuity of the surface of said floor and preferably by means of a material with high thermal inertia for storing heat and restoring it.
- the elements forming the uprights, crosspieces, walls and semi-walls are made of wood.
- wood as a building material has many advantages. It is a lightweight material and easy to carry. Its production is compatible with ecological standards, and responds to environmental concerns which now also occupy an important place in the choice of manufacturers.
- the figures 16 and 17 illustrate an example of a building made according to the construction method of the invention.
- the building is, in these examples, wood frame and residential use. It is substantially parallelepipedal in shape and comprises six faces. This building is intended to be placed on studs or fixed to the ground by appropriate means. It is easy to understand that one side of this building serves as a floor or floor (S), another side serves as a ceiling or roof (P) and two other faces (M1, M2) serve as walls with or without openings.
- the faces M3 and M4 may be closed by windows for example.
- the various steps of the method of construction of such a building are then presented according to one embodiment of the invention.
- the Figures 1 to 4 illustrate the stages of manufacture of the supporting framework and the Figures 5 to 16 the manufacturing steps of the envelope frames.

- each frame 100, 200, 300 consisting of vertical chevrons (or uprights) connected by horizontal rafters (or sleepers).
- the frame 100 comprises on a first side a first set of uprights 101 and on a second side a second set of uprights 102 parallel to the uprights 101, the uprights of each set being substantially equidistant and parallel to each other and of length equal.
- These two sets of uprights are connected by two sets of crosspieces 103, 104 perpendicular to the uprights.
- the crosspieces of each set 103, 104 are substantially equidistant and parallel to each other, and of equal length.
- the amounts are connected to the sleepers by screwing or any other appropriate means.
- a set of square-shaped openings is provided at the intersection of the uprights 102 and crosspieces 103 in particular. As will be seen later, these openings allow the passage of chevrons perpendicularly to the plane of the frame 100 in particular.
- the frames 200 and 300 are assembled on the same principle.
- the length of the uprights 202, 203 is smaller than that of the upright 201 so that the uprights 202, 203 do not protrude from the upper transom 204 once the uprights assembled to the struts 204, 205.
- the frames 100, 200, 300 consist of studs and transoms assembled cross.
- each frame 100, 200, 300 are fixed (by screwing for example) on one face of each frame 100, 200, 300 so as to stiffen them.
- the frame 100 for example, two plates 123, 127 are fixed on the uprights 102, 101 respectively and six plates 120 to 122 and 124 to 126 are fixed on the crosspieces 103, 104 respectively.
- the frame 200 only the plate 220 attached to the uprights 201, 202 is distinguished. Note that these plates are not all contiguous so as to allow the passage of beams. longitudinal composites connecting the frames 100, 200, 300 to each other, as illustrated on the Figures 3 and 4 .
- the frames 100, 200, 300 are interconnected by several sets of longitudinal longitudinal structural chevrons or crosspieces 10, 20, 30, 40, 50, 60 arranged perpendicular to the planes of the frames 100, 200, 300.
- Both structural chevrons 10 are inserted into the openings formed at the intersection of the uprights 102 and crosspieces 103 of the frame 100 and in identical openings in the frames 200 and 300.
- a clearance of the order of a few millimeters can be provided in a to allow the passage of the longitudinal chevrons in the openings of the frames and to take into account the swelling of the wood.
- the longitudinal chevrons are fixed to the frames by screwing, for example.
- the set of structural chevrons 40 consists of chevrons mounted in two perpendicular planes.
- a carrier structure also called a “supporting framework”, “structural trellis” or “skeleton" of a three-dimensional, parallelepiped-shaped building, which is rigid and self-supporting, and which comprises numerous contacts and intersections, is formed.
- This supporting structure is advantageous in that it does not require the implementation of structural elements of large section, such as planks, bastings.
- first internal envelope frame and a second outer envelope frame (around the first inner envelope frame) so as to form a formwork on at least one faces of the building.
- the inner and outer frames are spaced 15 or 40 cm, so as to form a formwork for an insulator whose thickness is chosen according to the thermal objectives.
- parallel chevrons S I are fixed on the bracing panel 72 in the same direction as the parallel chevrons S E (in a variant not shown, they may be perpendicular to the parallel chevrons SE).
- These rafters S I form the internal face of the ground / floor S. It is conceivable to fill the spaces / interstices between these rafters S I so as to ensure continuity of the surface of the ground S.
- the material that fills these spaces / interstices is for example, a material with high thermal inertia for storing heat and restoring it.
- parallel and equidistant vertical chevrons M2 I are arranged between the composite beams 30 and 40 so as to form the inner wall of the wall M2
- parallel and equidistant horizontal chevrons P I are arranged between the composite beams 10 and 30 so as to form the inner wall of the ceiling P.
- plywood bracing panels 80, 90 are attached to the rafters M2 I and P I on the outside of the building.
- Plywood bracing and sealing panels 82 are fixed between the posts 101, 201, 301 away from the boards 80 so as to form a form in which an insulator 81 can be inserted by blowing or filling ( figure 12 ).
- M2 E brackets which form the outer wall of the wall M2 ( figure 13 ) and which are perpendicular to the rafters M2 I.
- parallel and equidistant vertical chevrons MI E are arranged between the composite beams 10 and 60 so as to form the outer wall of the wall M1.
- the external frame consisting of rafters and bracing plates, is an external facing and that the plates of bracing associated or not with a rain screen provide a role of bulwark against bad weather.
- the faces M3 and M4 (not visible) of the dwellings illustrated on the figures 16 and 17 do not include a wall formed according to the principle described above, but can be closed by external joineries.
- the mounting of the frames is particularly advantageous in that it does not require complex cutting.
- the two frames are assembled by contact and fixing (screwing for example) of rafters, and require no corner piece.
- the edges are formed naturally by the intersection of chevrons of two faces. The cost of mounting the building is therefore reduced.
