Description

Title of the invention: Timber structure construction system, comprising beams with lateral recesses, and method based on such a system

[0001] The invention relates to the field of timber structure construction systems comprising a timber frame, posts and beams.

[0002] The innovation covers more specifically the field of positioning and anchoring construction modules in wooden structure (wooden frame, posts, beams) on a construction site. These modules are lifted using cranes and positioned on top of each other, and next to each other.

[0003] In this area, there is a growing need to optimize construction, and in particular to ensure: - a gravity load descent in accordance with the design office requirements; - an alignment of the anchors of the vertical and horizontal stability sails; - installation and control of anchors in accordance with the design office's requirements; - a limited number of reservations to be left in the modules allowing a very high level of prefabrication; and - a productivity gain when removing modules.

[0004] Thus, one objective of the invention is to remedy the defects of the prior art, and to propose an optimized construction system making it possible to ensure self-positioning of the wooden structure modules on top of each other at the time of removal, and rapid and auditable anchoring of the various stability walls of these modules.

[0005] To achieve this objective, the invention provides a system for constructing a wooden structure, comprising wooden stackers formed by vertical beams; characterized in that the stackers comprise at least one horizontal recess at the ends, supporting ceiling or floor boards of the upper floor.

[0006] Advantageously, the recesses make it possible to support the ceiling or floor boards.

[0007] According to one variant, the stackers extend over more than one level.

[0008] This allows for rigid reinforcement on one floor.

[0009] According to a variant, the stackers comprise at least two horizontal recesses perpendicular in a plane perpendicular to a beam axis.

[0010] This allows beams to be supported on different horizontal edges around the stacker.

[0011] According to one variant, the stackers are made of wood or steel.

[0012] This makes it possible to apply the invention to a timber frame structure and to fix the system to the rest of the timber frame.

[0013] According to a variant, the construction system further comprises hook-shaped fittings, and anchor rods fixed to the fittings, for anchoring vertical walls, and the assembled anchor rods extend over more than one floor.

[0014] This ensures self-positioning of wooden structure modules on top of each other at the time of removal; as well as rapid and auditable anchoring of the various stability walls of these modules.

[0015] According to one variant, the fittings support a floor or a ceiling and are supported by a rod.

[0016] This allows the floor or ceiling to be reinforced securely and effectively.

[0017] According to one variant, the fittings are fixed to a wooden reinforcement piece.

[0018] This helps to reinforce the rigidity of the construction.

[0019] According to a variant, the fittings comprise three plate segments perpendicular to each other, at least one rod passing through the first and / or the third plate segment.

[0020] This allows for a large rod assembly.

[0021] According to one variant, the construction system further comprises flat gussets fixing the floors and horizontal diaphragms. According to one variant, the gussets are in the form of metal plates.

[0022] This saves space above the slats fixed together.

[0023] The invention further relates to a wooden structure construction kit, for a construction system according to the invention, the construction kit comprising: - stackers; - the gussets; and - fittings and anchor rods.

[0024] Another object of the invention relates to a method of constructing a wooden structure, by means of a construction system according to the invention, the construction method comprising the following steps: - set up the stackers; - install ceiling or upper floor boards on said horizontal recess at the ends of the stackers.

[0025] The invention will be further detailed by the description of non-limiting embodiments, and on the basis of the appended figures, among which: - [Fig.l] illustrates a view in space of a spacer of a construction system according to a preferred variant of the invention; - [Fig.2] illustrates a view in space of the spacer of the previous figure in a timber frame construction, seen from the front and from behind; - [Fig.3] illustrates a spatial view of a gusset plate of a construction system according to a preferred variant of the invention, fixing two slats; - [Fig.4] illustrates a spatial view of a fitting and two anchor rods of a construction system according to a preferred variant of the invention, on a floor; - [Fig.5] illustrates a sectional view of the fittings and rods of the previous figure in a timber frame construction, seen from the front of the fittings; - [Fig.6] illustrates a sectional view of the fittings and rods in a two-story timber-framed building, seen from the fitting side.

[0026] The invention relates to a wooden structure construction system.

[0027] This type of construction includes a wooden frame, posts and beams. It requires positioning and anchoring, on site, of construction modules in wooden structure, wooden frames, posts, and beams.

[0028] The construction system comprises wooden stackers E formed by vertical beams.

[0029] According to the invention, the stackers E comprise at least one horizontal recess RI, R2, R3, R4 at the ends, illustrated in [Fig.l]. These reinforcements support boards P and slats L of the upper floor, or ceiling. In particular, the stackers E comprise at least two horizontal recesses RI, R2, R3, R4 perpendicular in a plane perpendicular to a beam axis.

[0030] These recesses delimit a beam base B below, and a beam apex A above. The beam apex A comprises fixing holes F0 for fixing the floor or ceiling slats. These fixing holes F0 receive fixing parts V such as screws.

[0031] In the preferred embodiment, the stackers E are made of wood or steel. Preferably, the stackers E extend over more than one level.

[0032] The construction system further comprises hook-shaped fittings F, and anchor rods T fixed to the fittings F, for anchoring vertical walls.

[0033] As can be seen in [Fig.4], the fittings F comprise three plate segments perpendicular to each other. The first segment is horizontal and low, the second is vertical and intermediate, and the third is horizontal and high. The lower rod T passes through the first plate segment. Another upper rod T passes through the third plate segment.

[0034] Furthermore, according to the invention, the anchor rods T assembled together with a fitting F, extend over more than one level.

[0035] In particular, the fittings F support a floor or a ceiling and are supported by a rod T.

[0036] As can be seen in [Fig.6], the fittings F are fixed to a wooden reinforcement piece R.

[0037] The construction system further comprises planar gussets G fixing the floors and horizontal diaphragms. Preferably, the gussets G are in the form of metal plates. They can connect several boards or slats together as illustrated in [Fig.3].

[0038] The invention further relates to a corresponding construction kit. The construction kit comprises the stackers E, the gussets G, the fittings F and the anchor rods T described above.

[0039] The invention also relates to a corresponding construction method.

[0040] The construction method comprises steps of installing the stackers E, the gussets G, the fittings F, and the anchor rods T, and finalizing the construction.
