Description

Technical Field

[0001] This utility model relates to the field of large-span spatial structural components, specifically a large-span airport double-layer interlocking lattice column. Background Technology

[0002] Traditional large-span spatial structures are numerous and varied, with highly complex nodes, which brings great difficulties to construction and greatly increases construction costs. Welding construction inevitably generates residual stress, which reduces the stiffness, strength and stability of structural components. Forced positioning during construction generates initial installation stress in the structure. Residual stress and initial installation stress pose great challenges to structural safety. Prefabricated building structures, due to their unique configuration, have been widely used in the construction of airports and other projects.

[0003] The publication number CN212358851U discloses a lattice column structure, including tie rods and four members of the same specification. The four members are symmetrically distributed at the four corners and are connected by tie rods to form a frame structure. The tie rods include several tie plates and tie strips.

[0004] The aforementioned lattice column structure has the advantages of ensuring quick and convenient on-site construction and high overall structural strength of the frame structure. However, during welding, the lattice plate has lower support strength on the outside and less welding space on the inside, making it easy for the lattice plate to deform and bend, reducing the overall rigidity and strength. Furthermore, the area for supporting the crossbeams is limited, making installation and fixing inconvenient. Utility Model Content

[0005] The purpose of this utility model is to provide a double-layer interlocking lattice column for large-span airports to solve the technical problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

Positioning components are installed at the top of the two steel columns. Each supporting component includes two lattice plates, which are welded to the sides of the two steel columns. A limiting plate is fixedly welded to the inner side of each lattice plate, and a support plate is fixedly welded to the inner side of the limiting plate. A first screw hole is opened through the outer side of one of the lattice plates, and a second screw hole is opened on the inner side of the support plate on the opposite side. A strut is connected inside the first and second screw holes, and the strut has internal and external threads at its two ends.

[0008] Preferably, the lattice plates are welded to both sides of the two steel columns and arranged at equal intervals, and the length between the two ends of the lattice plates matches the distance between the outer sides of the two steel columns.

[0009] Preferably, the support plate is used to support the inner walls of the two steel columns, and the distance between the limiting plate and the inner side of the two steel columns is matched.

[0010] Preferably, the outer diameter of the internal thread is smaller than the inner diameter of the first threaded hole, and the internal thread and the external thread are respectively threadedly connected to the second threaded hole and the first threaded hole.

[0011] Preferably, the positioning component includes a positioning plate and a fixing seat. The positioning plate is welded between two steel columns near the top. A positioning hole is opened through the top of the positioning plate. A connecting seat is fixedly welded to the top of each of the two steel columns. Triangular plates are fixedly welded to the top of the fixing seat near the four corners. A positioning block is fixedly installed in the center of the bottom of the fixing seat. A positioning column is fixedly installed in the center of the bottom of the positioning block.

[0012] Preferably, the fixing seat is connected to the two positioning plates by bolts, and the four triangular plates are respectively snapped onto the outside of the two steel columns.

At the same time, it can provide support for the inside of the two steel columns, reduce the stress at the weld. Through the connection of the struts, the fixation of the two lattice plates on both sides is enhanced, preventing deformation and bending, and improving the rigidity and strength of the two steel columns.

[0016] 2) This lattice column is equipped with a positioning component. Four triangular plates are snapped onto the outside of two steel columns, and a positioning block is snapped between the two steel columns.

The two steel columns 1 are fixed by welding the lattice plate 4 to both sides of the steel columns 1.

[0026] The support plate 6 is used to support the inner walls of the two steel columns 1. The distance between the limiting plate 5 and the inner side of the two steel columns 1 is matched. The support plate 6 supports the inner side of the two steel columns 1, reducing the stress at the weld.
