Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure trusses, and more specifically, particularly relates to a steel structure support truss with an anti-torsion function. Background Art

[0002] With the continuous development of society and the continuous progress of science, people often encounter support trusses in many large-scale activities. Support trusses are a structure composed of rods connected to each other by hinges at both ends. Trusses are generally plane or spatial structures with triangular units composed of straight rods. Truss rods mainly bear axial tension or pressure, so as to make full use of the strength of materials. When the span is large, it can save materials, reduce deadweight and increase rigidity compared with solid beams.

[0003] Most of the existing trusses are composed of multiple hollow rods and hinges (also including welding), which have the following advantages: first, the hollow rods are easy to transport before they are assembled and installed; second, they can be assembled according to the actual situation on site with a high degree of freedom; third, the hollow rods are light in weight, which is more conducive to building and assembling; however, the trusses composed of hollow rods also have obvious disadvantages: during the assembly and installation process, multiple groups of hollow rods are required at the fulcrum points, and the higher the height, the more layers need to be reinforced to avoid twisting and deformation of the trusses at the fulcrum points. This method undoubtedly increases the installation consumables and also reduces the overall construction progress of the trusses.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a steel structure support truss with anti-torsion function is provided, in order to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a steel structure support truss with anti-torsion function to solve the above problems.

[0006] The purpose and effect of the utility model of a steel structure support truss with anti-torsion function are achieved by the following specific technical means:

[0007] A steel structure support truss with anti-torsion function, comprising a hollow rod, an auxiliary support component is installed in the middle of the inner cavity of the hollow rod, a fixing component is provided on the outer wall surface of the left end of the hollow rod, and a force adjustment component is provided on the outer wall surface of the right end of the hollow rod;

[0008] The auxiliary support assembly comprises an equilateral triangular hollow rod, on the three outer wall surfaces of the equilateral triangular hollow rod are fixedly mounted a plurality of arc blocks, and on the three side outer wall surfaces of the equilateral triangular hollow rod are opened a plurality of limiting holes.

[0009] Furthermore, the fixing assembly includes an equilateral triangle block installed in the inner cavity of the left end of the equilateral triangle hollow rod, and the middle part of the three side outer wall surfaces of the equilateral triangle block are provided with a first threaded hole matching the limiting hole, and a fixing screw is installed between the first threaded hole and the limiting hole.

[0010] Furthermore, the fixing assembly also includes a threaded rod installed in the middle of the left outer wall of the equilateral triangle block, and a nut is installed on the threaded rod, and the diameter of the nut is larger than the inner diameter of the hollow rod.

[0011] Furthermore, the force adjustment component includes a cylindrical head, a triangular groove is opened in the middle of the right outer wall surface of the cylindrical head, and three special-shaped clamping blocks are evenly installed on the right wall surface of the cylindrical head.

[0012] Furthermore, a groove threaded hole matching the limiting hole is provided in the middle of the outer wall surface of the special-shaped clamping block, and a fixing screw is installed between the groove threaded hole and the limiting hole.

[0013] Furthermore, the force adjustment component also includes semi-cylindrical grooves evenly distributed on the left outer wall surface of the cylindrical head, and semi-cylindrical limit blocks are evenly installed on the right end outer wall surface of the hollow rod, and the semi-cylindrical limit blocks and the semi-cylindrical grooves are adapted to each other.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model installs an auxiliary support assembly in the inner cavity of the hollow rod, and fixes the auxiliary support assembly in the inner cavity of the hollow rod by cooperating with the fixing assembly and the force adjustment assembly, and rotates the hollow rod so that an outer edge of the equilateral triangular hollow rod in the inner cavity is vertically upward. When the upper surface of the hollow rod is subjected to a vertical downward force, the equilateral triangular hollow rod inside interacts with the arc block to cooperate with the hollow rod to bear the force as a whole, so that the truss as a whole has a better ability to resist torsional deformation.

[0016] 2. The utility model improves the overall anti-twisting and deformation ability of the truss at the fulcrum point by installing an auxiliary support assembly in the inner cavity of the hollow rod. Compared with the traditional truss construction, it reduces construction consumables, and the auxiliary support assembly can be installed in the inner cavity of the hollow rod in advance, thereby improving the speed of truss construction at the fulcrum point.
