Description

Technical Field

[0001] The utility model relates to a light wood building structure, in particular to a connection structure between an interlayer floor slab and a wall body. Background Art

[0002] A light wood building is a building with light wood structural lumber as the main material. Compared with concrete and steel structure buildings, it has the advantages of low energy consumption, heat insulation, earthquake resistance, high production efficiency, etc. In the prior art, light wood buildings are usually assembled on-site with various specifications of materials. First, wall studs are used in cooperation with oriented strand board (commonly known as OSB board) to set up the wall frame. The floor surface uses trusses or grids to be respectively lapped on the wall, and then the second-floor wall is built. This solution requires transporting all materials to the site for nailing or using metal connectors for local strengthening, resulting in a large amount of on-site work and large manual errors. There are also modular design solutions in the prior art. For example, large-sized wood wall panels are cross-laminated and then connected by self-tapping screws; or metal connectors are used to connect the joints of wall panels, but gluing or welding is required for cooperation to strengthen local connections. Both of the above two solutions have an impact on the overall assembly efficiency and structural design of the building, which is not conducive to the mass production of light wood buildings.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] As Figure 1 shown, a connection structure between an interlayer floor slab and a wall includes an upper wall module 1, a lower wall module 2, and a floor slab module 3 disposed between the upper wall module 1 and the lower wall module 2. The main parts of the upper wall module 1, the lower wall module 2, and the floor slab module 3 are made of light wood.

[0017] The upper wall module 1 includes a continuous bottom beam 4 at the bottom, and the lower wall module 2 includes a continuous top beam 5 at the top. The inner and outer sides of the upper wall module 1 and the lower wall module 2 are the outer wall and the inner wall respectively; one end of the floor slab module 3 extends into the space between the upper wall module 1 and the lower wall module 2, and is fixed to the continuous bottom beam 4 and the continuous top beam 5 respectively through a connection structure.

[0018] The upper and lower surfaces of the floor slab module 3 are the floor slabs connected to the upper and lower floors. A truss 6 is provided inside the floor slab module 3. The truss 6 extends along the horizontal direction to provide lateral support for the floor slab module 3. The truss 6 includes two groups of parallel upper chord bars and lower chord bars, and the upper chord bars and the lower chord bars are fixed by web members and vertical members. Along the extension direction of the truss 6, multiple groups of toothed plates 7 are provided to fix the connection points of the upper chord bars, the lower chord bars, the web members and the vertical members, and to enhance the support capacity of the truss 6. When the floor slab bears a load, the toothed plate 7 can disperse the load to various positions of the truss 6 to avoid local wooden members from being compressed and deformed. At the same time, the toothed plate 7 includes multiple serrated structures that engage with the truss 6, which can effectively prevent horizontal misalignment at each connection point and avoid local wooden members from being compressed and deformed.

[0019] Above the truss 6 is the upper floor slab, and below the truss 6 is the lower ceiling slab. Equipment pipelines, insulation cotton, etc. can be passed through the internal space of the truss 6 without perforating the floor slab module 3 additionally.

[0020] The connection structure includes two groups of connectors 10 respectively fixedly arranged in the upper wall module 1 and the lower wall module 2 for fixing the three modules. A perforation is preset in the middle of the connector 10, and a screw rod 8 is vertically arranged in the perforation. The screw rod 8 sequentially penetrates through the lower wall module 2, the through-length top beam 5, the floor slab module 3, the through-length bottom beam 4, and the upper wall module 1 from bottom to top. A threaded fastener 9 is also provided on the screw rod 8. The threaded fastener 9 is located outside the through-length top beam 5 and the through-length bottom beam 4. The threaded fastener 9 can be a nut, a bolt, etc. Tightening the threaded fastener 9 fastens the floor slab module 3. The setting of the upper and lower two groups of connectors 10 forms a two-way force on the floor slab module 3, and the shear resistance and pull-out resistance capabilities are more excellent. The connector 10 is made of L-shaped angle steel, and one side of it is pre-fixed on the wall studs of the upper wall module 1 and the lower wall module 2.

[0021] In this utility model, the vertically arranged screw rod 8 penetrates through the upper and lower walls and is tightened to form a structure with stronger integrity; in the horizontal direction, the wall and the floor slab are connected by the connector 10, and then the load is dispersed to various positions of the truss 6 by the toothed plate 7, having较强的抗剪切能力.

[0022] Furthermore, the upper wall module 1 and the lower wall module 2 are provided with reserved openings 11, which are located on the side of the threaded fastener 9 close to the inner wall. The threaded fastener 9 is tightened through the reserved openings 11. After the wall and the floor slab are assembled, skirting boards 12 and suspended ceilings 13 are respectively installed at the reserved openings 11 to complete the assembly of the entire building. Similarly, a waistline 14 is provided between the outer walls of the upper wall module 1 and the lower wall module 2. After the floor slab module 3 is assembled, the waistline 14 is covered at the joint between the outer wall and the floor slab module 3 to hide the joint between the modules and enhance the integrity of the building. An installation groove for the waistline is reserved on the outer wall side, and a space for later installation of the skirting board 12 is provided on the inner wall side, realizing the separation of decoration and structure.

[0023] In this embodiment, each module is prepared separately and then connected and supported by the light truss 6 and standard hardware. It has the advantages of being easy to mass-produce and assemble without affecting the supporting force. The specific assembly process is as follows: The upper wall module 1 and the lower wall module 2 are prepared separately, and angle steel connectors 10 are respectively arranged inside the upper wall module 1 and the lower wall module 2; the position of the truss 6 inside the floor slab module 3 is fixed by the truss tooth plate 7 to enhance the bearing capacity of the truss 6; one end of the floor slab module 3 is extended between the upper wall module 1 and the lower wall module 2, and a through-length top beam 5 and a through-length bottom beam 4 are respectively installed on the upper and lower sides of the floor slab module 3. A vertically arranged screw 8 is inserted, and the screw 8 sequentially passes through the through-length bottom beam 4, the floor slab module 3, and the through-length top beam 5, and bolts on both sides are tightened from the inner wall to fix the overall position of the floor slab module 3. Finally, skirting boards 12 are filled in the inner sides of the through-length bottom beam 4 and the through-length top beam 5, and finishes and waistlines 14 are filled in the outer sides of the through-length bottom beam 4 and the through-length top beam 5 to complete the assembly of the entire building.

Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
