Description

Technical Field

[0001] This utility model relates to the field of steel trusses, and in particular to lightweight steel trusses. Background Technology

[0002] A truss is a structure composed of members connected at both ends by hinges. Trusses are planar or spatial structures typically composed of straight members and triangular units. Truss members primarily bear axial tension or compression, thus making full use of the material's strength. For large spans, they can save material compared to solid-web beams, reducing self-weight and increasing stiffness. The advantages of trusses are that the members primarily bear tension or compression, fully utilizing the material's potential, saving material, and reducing structural weight. Commonly used types include steel trusses, reinforced concrete trusses, prestressed concrete trusses, timber trusses, steel-timber composite trusses, and steel-concrete composite trusses. Based on the axes of the truss members and the distribution of external forces, trusses can be classified into planar trusses and spatial trusses.

[0003] However, steel trusses are a common type of truss. Traditional steel trusses, such as the technical solution protected by the patent application number CN201921380623.0, entitled "A Steel Truss", have low structural strength and poor structural stability. Utility Model Content

[0022] Please refer to the following: Figures 1 to 4 The present invention provides a lightweight steel truss 10, which includes: a frame 100, a plurality of support mechanisms 200 and a plurality of connecting mechanisms 300.

[0023] The frame 100 includes four connecting posts 110 and several square connecting frames 120. Each square connecting frame 120 is evenly arranged in a row on the four connecting posts 110, and each corner of a square connecting frame 120 is connected to a corresponding connecting post 110. A limiting groove 101 is formed in the middle area of ​​the inner wall of each side of the square connecting frame 120. In this embodiment, all four connecting posts 110 and the square connecting frames 120 are hollow structures.

[0024] The support mechanism 200 includes a connecting platform 210 and two support rods 220. In this embodiment, the connecting platform 210 is a cylindrical structure. In another embodiment, the connecting platform 210 is a cuboid structure. A driving groove 201 is provided at one end of the connecting platform 210, and two sliding grooves 202 are symmetrically provided on both sides of the connecting platform 210, both of which communicate with the driving groove 201. A connecting groove 203 is provided at the end of the connecting platform 210 away from the driving groove 201. A passive inclined surface is provided at one end of the support rod 220, and a limiting post 221 is provided at the end of the support rod 220 away from the passive inclined surface. The limiting post 221 is adapted to the limiting groove 101 and can be inserted into a limiting groove 101 and connected to one inner wall of the square connecting frame 120. In this embodiment, the limiting post 221 is a cylindrical structure. In another embodiment, the limiting post 221 is a quadrangular prism structure.

[0025] The support rods 220 within two adjacent support mechanisms 200 are vertically arranged. The two adjacent support mechanisms 200 are connected by a connecting mechanism 300. The connecting mechanism 300 includes a rotating screw 310, a receiving post 320, and an insertion post 330. The rotating screw 310 is adapted to a connecting groove 203 and can be inserted into the connecting groove 203 and connected to a connecting platform 210. One end of the rotating screw 310 is provided with a rotating handle 311. In this embodiment, the rotating handle 311 and the rotating screw 310 are integrally formed, and the rotating handle 311 is a straight handle. Further, the rotating handle 311 is provided with anti-slip texture. In this embodiment, the receiving post 320 is a quadrangular prism structure. In another embodiment, the receiving post 320 is a cylindrical structure. One end of the receiving post 320 has a threaded hole 301. A rotating screw 310 is fitted into the threaded hole 301 and can be inserted into the threaded hole 301 and screwed onto the receiving post 320. The end of the receiving post 320 away from the rotating screw 310 is connected to an insertion post 330. Driving inclined surfaces are provided on both sides of the end of the insertion post 330 away from the receiving post 320. The driving inclined surfaces are fitted into the passive inclined surfaces, and each driving inclined surface can slide against a corresponding passive inclined surface.

[0026] During the assembly of the aforementioned lightweight steel truss 10, the first support mechanism 200 is placed inside the first square connecting frame 120, and the limiting posts 221 on each support rod 220 of the first support mechanism 200 are correspondingly inserted into a limiting groove 101.

The insertion post 330 in the first connecting mechanism 300 is welded to the connecting platform 210 in the second support mechanism 200. Rotating the handle 311 drives the rotating screw 310 to rotate, causing it to be pulled out of the threaded hole 301 and ultimately inserted into the connecting groove 203 on the connecting platform 210 of the first support mechanism 200. The rotating screw 310 is then welded to the connecting platform 210 of the first support mechanism 200. This process is repeated to assemble the lightweight steel truss 10. The aforementioned lightweight steel truss 10 is easy to assemble and exhibits high structural strength and stability. The technical features of the above embodiments can be combined in any way.
