Description

Technical Field

[0001] This utility model belongs to the technical field of wooden shear walls, specifically, it relates to a connection structure for a lightweight wooden shear wall. Background Technology

[0002] In the field of modern architecture, lightweight wood structures are widely used due to their advantages such as environmental protection and convenient construction. Among them, shear walls, as the main lateral force resisting components, directly affect the overall seismic and wind resistance performance of the building due to the reliability of their connection structure.

[0003] Existing lightweight timber shear wall connections primarily employ traditional nail, bolt, or metal connectors. However, nail connections have limited shear strength and are prone to loosening and slippage under heavy loads. While ordinary bolt connections provide some strength, the anisotropy and deformation characteristics of wood can lead to gaps between the bolt and the wood, resulting in decreased connection performance. Some metal connectors are complex in structure, cumbersome to install, and fail to effectively enhance the overall shear resistance of the shear wall. With the increasing demands for safety and stability in the construction industry for lightweight timber structures, there is an urgent need for a shear wall connection structure that is simple in structure, easy to install, and can significantly improve shear resistance to meet practical engineering needs.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A connection structure for a lightweight timber shear wall includes a first timber splicing wall and a second timber splicing wall; the first and second timber splicing walls are spliced ​​together; splicing protrusions and splicing grooves are respectively provided on the left and right sides of the first and second timber splicing walls; multiple positioning grooves are provided on the front and rear sides of adjacent first and second timber splicing walls; the adjacent first and second timber splicing walls are tightened front and rear by longitudinal positioning components; the splicing protrusions are fixed to the side walls of the first and second timber splicing walls by transverse positioning components.

[0007] In a preferred embodiment of the present invention, the longitudinal positioning component includes a positioning steel plate that is movably embedded in a positioning groove, and the two longitudinally aligned positioning steel plates are fixed together by two horizontally aligned longitudinal bolts.

[0008] In a preferred embodiment of the present invention, the transverse positioning component includes a transverse bolt and a first steel pad and a second steel pad respectively embedded in the outer wall of the splicing protrusion, the inner wall of the splicing groove, and the outer wall of the filling block.

[0009] In a preferred embodiment of this utility model, the first steel pad and the second steel pad are connected by a transverse bolt that passes through the first wooden splicing wall and the splicing protrusion, and thus form a locking connection.

[0010] In a preferred embodiment of this utility model, the filling block is embedded in the splicing groove opened in the outermost second wooden splicing wall.

[0011] In a preferred embodiment of this utility model, the positioning steel plate is a galvanized steel plate.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] A three-dimensional fastening system is formed by bolts sequentially passing through the second steel pad, the wooden spliced ​​wall, the splicing protrusion, and the first steel pad. This system is further enhanced by the mortise and tenon joint between the splicing protrusion and the splicing groove, and the longitudinal bolts passing through the wooden spliced ​​wall to lock onto the positioning steel plate. This structural design effectively restrains adjacent wooden spliced ​​walls in both horizontal and vertical directions, greatly improving the overall shear resistance. Compared with traditional connection methods, it can effectively resist lateral loads such as strong winds and earthquakes, significantly enhancing the structural stability and safety of lightweight wood-frame shear walls.

[0014] Simplified installation process and improved construction efficiency: This connection structure adopts a modular design concept, with precise matching of splicing protrusions and grooves, and a quick positioning method between the positioning steel plate and the positioning groove, enabling construction workers to quickly align and fix wall components. The step-by-step tightening of horizontal and vertical bolts is simple, requiring no complex installation equipment or professional skills, reducing construction difficulty, shortening the construction cycle, and significantly improving the construction efficiency of lightweight wood-frame buildings.

[0015] Enhancing structural integrity and durability: The use of steel pads and positioning steel plates effectively disperses the local stress generated by bolt tightening, preventing the wood from cracking and breaking due to stress concentration; at the same time, the dual connection method of mortise and tenon splicing and bolt locking reduces the gaps caused by wood deformation under stress, prevents loosening of connecting parts, and ensures that the connection structure maintains good mechanical properties during long-term use, significantly improving the durability and service life of lightweight wood shear walls.
