Description

A type of stable steel truss Technical Field

[0001] This utility model relates to the field of steel truss technology, and in particular to a stable steel truss. Background Technology

[0002] A steel truss is a truss structure made of steel, widely used in large-scale projects such as industrial and civil buildings, bridges, hydraulic gates, and towers. Its main characteristic is the use of triangular units to connect members at hinged nodes, forming a load-bearing structure. During the assembly and installation of steel trusses, bolted connections are typically used for temporary or final fixation.

[0003] In existing technologies, bolts require a large preload to ensure tightness and reliability during connection. However, once the bolts are tightened, the nuts may become stuck due to excessive friction, making disassembly difficult. Therefore, we propose a robust steel truss to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a stable steel truss.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stable steel truss includes four first round steel bars and four second round steel bars. Each of the four first round steel bars and four second round steel bars has a butt joint hole at its top and a butt joint pipe fixedly connected to its bottom. A top plate is fixedly connected to the top of each of the first round steel bars and two second round steel bars, and a bottom plate is fixedly connected to the top of each of the first round steel bars and two second round steel bars. A circular hole is formed on the outer wall of the bottom plate, and a T-shaped column is rotatably connected to the inner wall of the circular hole. A connecting rod is fixedly connected to the bottom of the T-shaped column. A connecting assembly is provided between the top plate and the bottom plate.

[0007] Preferably, the connecting assembly includes two pins, and the outer walls of the top plate and the bottom plate each have two insertion holes. The four insertion holes are slidably connected to the outer walls of the two pins in pairs. The outer walls of the pins have pin holes, and the outer walls of the top plate have rectangular docking grooves. The two sets of steel trusses are docked by setting the connecting assembly.

[0008] Preferably, the outer walls of both the first and second round steel bars are fixedly connected with multiple diagonal braces, thereby increasing the stability of the steel truss.

[0009] Preferably, the outer walls of both the first and second round steel bars are fixedly connected with horizontal support rods, thereby increasing the stability of the steel truss.

[0010] Preferably, a U-shaped gasket is placed between the top plate and the bottom plate to avoid rigid compression between the top plate and the bottom plate.

[0011] Preferably, the two pins are located at both ends of the connecting rod, and the connecting rod is rotated and limited by the pins.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution enables rapid initial positioning of the steel truss through the insertion and connection of the connecting pipe and the docking hole, significantly improving construction efficiency and reducing high-altitude adjustment time. The rotational locking design of the connecting rod and the rectangular docking slot allows for rapid final fixation of the upper and lower trusses after initial docking, preventing nuts from jamming and making disassembly more flexible. The cooperation between the pin and the insertion hole, combined with cotter pin fixing, forms a mechanical limit, effectively preventing the connecting rod from rotating or detaching accidentally, ensuring the stability of the truss under wind loads or earthquakes. The rotation mechanism of the T-shaped column allows the connecting rod to be reliably locked, avoiding the loosening problem caused by vibration of traditional bolts. Attached Figure Description

[0023] As shown in Figures 1-5, a stable steel truss is described, comprising four first round steel bars 1 and four second round steel bars 2. The surfaces of the first round steel bars 1 and the second round steel bars 2 are hot-dip galvanized or sprayed with epoxy zinc-rich paint. Multiple diagonal web members 3 are fixedly connected to the outer walls of the first round steel bars 1 and the second round steel bars 2. Horizontal support rods 4 are fixedly connected to the outer walls of the first round steel bars 1 and the second round steel bars 2. Full penetration welds are used at the nodes of the diagonal web members 3 to ensure continuous force transmission.

[0024] The tops of the four first round steel bars 1 and the four second round steel bars 2 are all provided with mating holes 5, and the bottoms of the four first round steel bars 1 and the four second round steel bars 2 are all fixedly connected with connecting pipes 6. The mating holes 5 and the connecting pipes 6 cooperate to allow the two steel trusses to be connected.

[0025] The top of the first round steel 1 and the second round steel 2 are both fixedly connected to the top plate 7, and the top of the first round steel 1 and the second round steel 2 are both fixedly connected to the bottom plate 8. A U-shaped gasket 9 is placed between the top plate 7 and the bottom plate 8. The U-shaped gasket 9 is made of rubber and can effectively buffer vibration and prevent direct metal contact to generate noise. A round hole is opened on the outer wall of the bottom plate 8. A T-shaped column 10 is rotatably connected to the inner wall of the round hole. A connecting rod 11 is fixedly connected to the bottom of the T-shaped column 10. The connecting rod 11 rotates through the T-shaped column 10.

[0026] A connecting assembly is provided between the top plate 7 and the bottom plate 8. The connecting assembly includes two pins 13, which are located at both ends of the connecting rod 11. The two pins 13 are offset from each other by a distance equal to the width of the connecting rod 11. Two insertion holes 12 are provided on the outer walls of both the top plate 7 and the bottom plate 8. The four insertion holes 12 are slidably connected to the outer walls of the two pins 13 in pairs. The outer walls of the pins 13 are provided with pin holes 14. The pins 13 mainly prevent the connecting rod 11 from rotating and avoid sliding out of the rectangular docking groove 15. The outer walls of the top plate 7 are provided with rectangular docking grooves 15.

[0027] Working principle: The steel truss is composed of four first round steel bars 1, multiple diagonal web members 3, and multiple horizontal support rods 4. When installing two steel trusses together, the two steel trusses are slid into the four docking holes 5 through the four docking pipes 6 to achieve preliminary docking. During docking, the connecting rod 11 is aligned vertically with the rectangular docking groove 15 so that the connecting rod 11 passes through the rectangular docking groove 15. Subsequently, the connecting rod 11 is rotated so that it is offset from the rectangular docking groove 15 by 90 degrees. Then, the two pins 13 are slid into the two insertion holes 12 on the outer walls of the bottom plate 8 and the top plate 7, respectively. Due to the preliminary docking, the two insertion holes 12 on the outer walls of the bottom plate 8 and the top plate 7 are aligned vertically. Then, the existing cotter pin is inserted into the pin hole 14 to limit the rotation of the connecting rod 11, thereby preventing the upper and lower steel trusses from moving up and down, improving vertical pull-out stability and long-term stability.
