Description

Title of the invention: Prefabricated crown module in wooden structure, construction system and method based on such a module

[0001] The invention relates to the field of timber frame construction systems. The invention relates more particularly to flat roofs (also called "flat roofs"), of the factory-made type and crowning a traditional construction module.

[0002] In this field, roof construction remains extremely artisanal, requiring high levels of qualification and dangerous working situations (working at height, exposure to bad weather, etc.).

[0003] The installation of the framework, waterproofing and roofing can also require the intervention of several trades, making the work on construction sites more expensive and complex.

[0004] Finally, quality assurance of the value chain is sometimes difficult to maintain.

[0005] Thus, one objective of the invention is to remedy the defects of the prior art, and in particular to propose an effective roof construction solution, limiting the danger for operators.

[0006] To achieve this objective, the invention proposes a timber frame crowning module for a timber frame housing module equipped with vertical beams fixed to a frame crown, the crowning module including: - a timber frame roof crown configured to be fixed to the roof frame crown; - an acroterion fixed around the roof crown, secured to the roof crown; - wooden frame boxes forming a roof support, secured to the roof crown, and comprising a floor slab forming the upper face of the boxes.

[0007] Advantageously, the invention proposes to make the construction of the roof more efficient by prefabricating the flat roof complex, including the waterproofing and the acroteria (and any additions) on a first site off the construction site, for example in a factory; then lifting and installing said complex on the construction site using a crane for example.

[0008] According to a variant, the acroterion comprises a first thermal insulation, preferably from the outside.

[0009] This makes it possible to isolate the junction between the acroterion and the rest of the crowning module by breaking the thermal bridges.

[0010] According to one variant, the floor slab is equipped with an EPDM rubber covering.

[0011] This provides a rigid surface on which people can walk.

[0012] According to one variant, the floor slab includes a plant cover.

[0013] This makes it possible to embellish the crowning module and / or to create an ecological construction.

[0014] According to one variant, the floor slab comprises a second thermal insulation, preferably from the outside.

[0015] This allows the roof to be thermally insulated.

[0016] The first and / or second external thermal insulation makes it possible to limit the space taken up in the areas where the acroterion or slabs are fixed, in order to have effective fixing and insulation.

[0017] According to a variant, the roof crown internally comprises at least one support tab for the boxes, said tab preferably having a downward slope.

[0018] This allows the boxes to be simply and securely supported on the roof crown, and the boxes to be fixed to the rest of the crown module. The slope allows rainwater drainage standards to be met.

[0019] Preferably, two first opposite edges of the roof crown each comprise a first support tab, and two second edges consecutive to the first edges, each comprise a second support tab in continuity with said first support tab.

[0020] According to a variant, the crowning module is for a housing module whose frame crown comprises a first cooperation structure, and the roof crown comprises a second cooperation structure cooperating with the first cooperation structure, so that the first and second cooperation structures fit into each other.

[0021] This allows for good positioning / alignment and good holding of the crowning module on the housing module, regardless of the subsequent fixing of these modules.

[0022] The invention further relates to a timber-framed housing module for a crown module according to the invention, the housing module comprising a roof crown and vertical beams fixed to the roof crown, characterized in that the roof crown comprises a first cooperation structure cooperating with the roof crown, or with a second cooperation structure on the roof crown, so that the first cooperation structure and the second cooperation structure or the roof crown fit into each other.

[0023] The invention further relates to a timber structure construction system, comprising: - at least one timber-framed housing module comprising a frame crown and vertical beams fixed to the frame crown; and - at least one crowning module according to the invention, for said housing module.

[0024] Another object of the invention relates to a method of constructing a timber-framed building comprising steps for: - manufacture at least one crowning module according to the invention; - install and fix said crown module on a timber-framed housing module comprising a frame crown and vertical beams fixed to the frame crown.

[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 spatial view of a crowning module and a corresponding housing module, according to the invention; - [Fig.2] illustrates a view in the space of manufacturing steps of the crowning module according to an embodiment of the invention; - [Fig.3] illustrates a side view showing the inside of an edge of the roof crown equipped with a support tab; - [Fig.4] illustrates a spatial view of an assembly of several housing modules according to the invention arranged horizontally, with a corresponding crowning module; - [Fig.5] illustrates a spatial view of an assembly of several housing modules according to the invention arranged vertically, with a corresponding crowning module.

[0026] The invention relates to a timber frame construction system, comprising at least one crowning module T and at least one housing module H.

[0027] This type of construction includes a wooden frame, P posts and beams.

[0028] The innovation relates to a concept of a terrace roof (flat roof - hereinafter "T crowning module") manufactured in the factory and intended to crown an H housing module. Depending on the specifications, the T crowning module can accommodate vegetation and / or be passable.

[0029] Innovation has a number of advantages: - transfer roofing work to ground level, thus reducing the arduousness and danger of the tasks; - to make the treatment of the lower floors of the structure (also built in a modular way) completely independent of the type of roof; and - enable considerable productivity gains compared to traditional roofing work.

[0030] As can be seen in [Fig. 1], a timber-framed housing module H comprises, in particular, vertical beams P and a frame crown Cl. The beams P are fixed to the frame crown Cl.

[0031] The crowning module T is adapted to the housing module H, particularly in terms of dimensions as illustrated in [Fig.l].

[0032] The crowning module T comprises a timber-framed roof crown C2 configured to be fixed to the roof frame crown CL

[0033] In the preferred variant, the roof crown C1 comprises a first cooperation structure SI illustrated in [Fig.l]. Thus, the roof crown C2 comprises a second cooperation structure S2 cooperating with the first cooperation structure SI, so that the first SI and second S2 cooperation structures fit into each other when the crown module T is placed on the housing module H.

[0034] Alternatively, it can be envisaged that the frame crown C1 and the roof crown c2 fit into each other.

[0035] The crowning module T further comprises an acroterion A fixed around the roof crown C2. The acroterion A is secured to the roof crown C2. It comprises a first thermal insulation II, in particular external thermal insulation better visible at the bottom of [Fig.2].

[0036] The crown module T further comprises wooden frame CT boxes forming a roof support. The CT boxes are secured to the roof crown C2.

[0037] In the preferred variant, the roof crown C2 comprises internally, on each edge, a support tab L for the boxes CT. The tab L is shown on a length edge forming the roof crown C2 in [Fig.2]. The tab L has a downward slope. Preferably, the tab L of the length edge is continuous with a width tab (not shown), so as to extend the slope in the length and width directions.

[0038] In the illustrated variant, the boxes comprise a floor slab D forming their upper face. In particular, the floor slab D is equipped with an EPDM rubber coating visible in [Fig.l]. This makes the slab D walkable. It can support the weight of several people walking on it. Furthermore, this makes the roof waterproof.

[0039] Alternatively or in combination with the above-mentioned covering, the floor slab D may include a vegetated covering better visible in figures 3 and 4.

[0040] Preferably, the floor slab D comprises a second thermal insulation 12, in particular external thermal insulation.

[0041] The crowning module T may comprise an insulation complex according to the user's needs.

[0042] The invention can be implemented in constructions of various types at several geographical locations.

[0043] The invention further relates to a corresponding H-housing module; and a construction system comprising at least one crowning module as described above, and a corresponding H-housing module.

[0044] Another object of the invention relates to a corresponding construction method.

[0045] The construction method comprises at least two steps: - prefabrication of the roof terrace complex (capping module T), including waterproofing and acroteria A, in the factory. The solution can accommodate a standard EPDM type covering, a plant cover or be accessible for people; - lifting and installation of the crown module T on a corresponding residential module H on a construction site, for example using a crane.
