Description

Technical Field

[0001] This utility model relates to the field of shear wall connection technology, specifically a toothed groove connection structure for the upper and lower inner wall panels of a shear-resistant shear wall. Background Technology

[0002] Shear walls, also known as wind-resistant walls or earthquake-resistant walls, are the main walls in a building that bear horizontal and vertical loads. Their core function is to transfer horizontal forces to the foundation through their own stiffness and strength, preventing shear failure and thus ensuring the overall stability of the building.

[0003] Existing methods for connecting the upper and lower interior wall panels of shear walls often involve direct butt joints, resulting in poor stability and making it difficult to achieve a secure connection using toothed or grooved joints. Therefore, we propose a toothed or grooved connection structure for the upper and lower interior wall panels of shear walls. Utility Model Content

[0004] The purpose of this utility model is to provide a toothed groove connection structure for the upper and lower inner wall panels of a shear wall, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a toothed groove connection structure for upper and lower inner wall panels of a shear-resistant shear wall, comprising a lower wall panel and an upper wall panel. The top of the lower wall panel is fixed with a plurality of evenly distributed teeth. The bottom of the upper wall panel is provided with matching tooth grooves corresponding to the teeth. A through hole is provided on the lower side of one side wall of the upper wall panel corresponding to the teeth, and the through hole communicates with the tooth groove. The outer wall of the teeth is provided with threaded holes, and the threaded holes correspond to the through holes.

[0006] By adopting the above technical solution, the upper wall panel and the lower wall panel are first aligned so that the teeth and grooves can be inserted. Then, the bolt is passed through the through hole so that the bolt and the threaded hole can be engaged and connected, so that the teeth can be limited, thus making the connection between the upper wall panel and the lower wall panel stable. The upper wall panel and the lower wall panel are connected by multiple teeth, which helps to improve the stability of the connection between the upper wall panel and the lower wall panel.

[0007] In a preferred embodiment of the present invention, a clamping plate is provided on the top of the tooth, and a movable rod is fixedly connected to the bottom of the clamping plate. A circular groove is provided on the top of the tooth, and a through hole is provided at the bottom of the inner cavity of the circular groove. The through hole and the threaded hole are connected. The tail end of the movable rod is inserted into the through hole and extends into the threaded hole. The tail end of the movable rod is provided with an inclined surface.

[0008] By adopting the above technical solution, when the bolts are engaged with the threaded holes on the side wall of the upper wall panel and the teeth, the bolts can be pressed against the tail end of the movable rod, thereby pushing the movable rod to move upward, which in turn causes the pressing plate to move upward, and then the pressing plate can be pressed against the top of the tooth groove cavity, thereby achieving reverse pressing and limiting the bolt position, which is conducive to further improving the stability after connection.

[0009] In a preferred embodiment of this utility model, a spring is fitted on the upper side of the outer wall of the movable rod, one end of the spring is fixedly connected to the bottom of the abutment plate, and the tail end of the spring is fixedly connected to the bottom of the inner cavity of the circular groove.

[0010] By adopting the above technical solution, the spring can pull the clamping plate, so that during disassembly, the clamping plate can be pulled back to its original position by the spring, while preventing the clamping plate and the movable rod from disengaging from the teeth.

[0011] In a preferred embodiment of this utility model, positioning posts are fixed on both sides of the top of the lower wall panel, and positioning holes are opened at the bottom of the upper wall panel corresponding to the positioning posts, with the positioning posts inserted into the positioning holes.

[0012] By adopting the above technical solution, when connecting the upper and lower wall panels, the positioning posts and positioning holes are used to quickly connect the upper and lower wall panels, allowing the teeth to quickly align with the grooves at the bottom of the upper wall panel, thereby improving the accuracy of the connection. At the same time, the connection of the positioning posts and positioning holes can further improve the stability of the connection.

[0013] In a preferred embodiment of the present invention, the side wall of the upper wall panel is provided with recessed grooves corresponding to the plurality of through holes, and the through holes are disposed in the recessed grooves.

[0014] By adopting the above technical solution, the recessed groove is designed so that the bolt can be contained in the inner cavity of the recessed groove after the bolt is connected, which helps to prevent the bolt from protruding from the wall surface after connection and affecting subsequent operations.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The present application provides a toothed groove connection structure for the upper and lower inner wall panels of a shear wall, which uses teeth and grooves for interlocking to achieve multiple limiting connections, thereby improving the stability of the connection.

[0017] When the bolt engages with the threaded hole on the side wall of the upper wall panel and the tooth, the bolt can be pressed against the end of the movable rod, thereby pushing the movable rod to move upward, which in turn causes the clamping plate to move upward, and then the clamping plate can be pressed against the top of the tooth groove cavity, thereby achieving reverse clamping and limiting the bolt, which helps to further improve the stability of the connection.

[0018] By using positioning posts and positioning holes, the upper and lower wall panels can be quickly connected, and multiple teeth can be quickly inserted into the corresponding grooves, which helps to improve the accuracy of the connection. At the same time, the positioning posts can further enhance the stability of the connection. Attached Figure Description
