Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy lattice shell construction, in particular to an aluminum alloy lattice shell node fixing device used for greenhouse exhibition hall construction. Background Art

[0002] Aluminum alloy materials have the advantages of light weight, high strength, and strong corrosion resistance, which not only meet the requirements of building performance, but also make the building more economical and reasonable. Aluminum alloy lattice shell structure is formed by connecting aluminum alloy profiles through various nodes. Due to its light weight and high strength, it is widely used in buildings, such as large-span exhibition halls, gymnasiums, railway stations, etc.

[0003] The aluminum alloy lattice shell node fixing device on the market is in use. Once the adjacent rods of the node are fixed to the node during the installation process, the rod length and the node position are completely determined. However, in actual projects, due to the influence of factors such as rod cutting length error, node positioning deviation and temperature change during installation, installation errors are inevitable in the installation of the spatial grid structure, making it difficult to install the rods normally or the nodes deviate from the designed position, resulting in the actual shape of the structure having initial geometric defects compared with the designed shape, affecting the stability and safety of the structure under the use load. For this reason, we propose an aluminum alloy lattice shell node fixing device for greenhouse exhibition hall construction. Utility Model Content

[0026] In the above structure, the H-profile is usually an aluminum profile, and the H-profile connector 4 is used to connect with the H-profile on the surrounding side, so as to form an integral connection of the node; wherein, since each connecting shaft 3 can rotate independently, and the H-profile connector 4 is fixedly arranged on the side of each connecting shaft 3 in a one-to-one correspondence, each H-profile connector 4 can rotate around the connecting shaft 3 to adjust its angle, so that each H-profile connector 4 can adapt to the angle change of the H-profile docked on the surrounding side of the node; in addition, since the H-shaped slot 401 has a certain depth, there is also adjustable space in the length direction of the H-profile to adapt to a certain installation error; during the installation process, the H-profile can be directly inserted into the H-shaped slot 401 of the H-profile connector 4, and then the connection and fixation of the H-profile on the surrounding side of the node is completed by driving a screw into the connecting screw hole 402;
