[0028] The utility model provides a prefabricated long-span steel truss, which includes a steel truss body 1. The steel truss body 1 is provided with a first steel truss 2 in the up-and-down direction to facilitate the bearing of each component. Tubular rods in the up-and-down direction are arranged at the four corners of the first steel truss 2 to facilitate the installation of each component. An annular groove with threads is opened on the outer circumference of the top of the tubular rod of the first steel truss 2 to facilitate the installation of the assembly fixing cylinder 4 through threads.

A second steel truss 3 in the up-and-down direction is arranged on the top of the first steel truss 2 to facilitate assembly. Tubular rods in the up-and-down direction are arranged at the four corners of the second steel truss 3 to facilitate the assembly with the first steel truss 2. An annular groove with threads is opened on the outer circumference of the bottom of the tubular rod of the second steel truss 3 to facilitate the screwing in of the assembly fixing cylinder 4. An up-and-down assembly fixing cylinder 4 is installed through threads in the annular groove between the second steel truss 3 and the first steel truss 2 to facilitate assembly and fixation. Threads are opened on the inner circumference of the assembly fixing cylinder 4 to facilitate installation through threads. A regular hexagon structure is arranged on the outer circumference of the assembly fixing cylinder 4 to facilitate rotation by tools.
[0029] Among them, a rotation adjustment cylinder 5 in the up-and-down direction is installed through threads on the outer circumference of the upper part of the tubular rod of the first steel truss 2 to facilitate the lifting and lowering of the rotation adjustment cylinder 5 through thread engagement. Threads are opened on the inner circumference of the rotation adjustment cylinder 5 to facilitate installation through threads. A regular hexagon structure is arranged on the outer circumference of the bottom of the rotation adjustment cylinder 5 to facilitate rotation by tools. A bearing ring groove is opened on the inner circumference of the top of the rotation adjustment cylinder 5 to facilitate the installation of the moving bearing cylinder 6 through a bearing. A moving bearing cylinder 6 in the up-and-down direction is installed through a bearing in the bearing ring groove of the rotation adjustment cylinder 5 to facilitate the synchronous movement of the rotation adjustment cylinder 5 driving the moving bearing cylinder 6. A bearing ring groove is opened on the outer circumference of the bottom of the moving bearing cylinder 6 to facilitate the installation of the rotation adjustment cylinder 5 through a bearing. A threaded hole is opened on the outer side wall of the upper part of the moving bearing cylinder 6 to facilitate the installation of the fixing synchronous column 7 through threads. A wear-resistant layer is arranged on the inner circumferential surface of the moving bearing cylinder 6 to facilitate the extension of the service life.

A regular hexagon groove is opened on the outer end face of the fixing synchronous column 7 to facilitate disassembly and assembly by tools. The inner end of the fixing synchronous column 7 is installed with an up-and-down assembly stress column 8 through threads to facilitate the synchronous movement of the moving bearing cylinder 6 driving the assembly stress column 8 through the fixing synchronous column 7. A threaded blind hole is opened on the outer circumference of the lower end of the assembly stress column 8 to facilitate the installation of the fixing synchronous column 7 through threads.
[0030] The specific usage mode and function of this embodiment:
[0031] In the present utility model, as Figure 1 shown, the first steel truss 2 and the second steel truss 3 are in an assembled and fixed state. At this time, the assembly fixing cylinder 4 is at the butt joint of the first steel truss 2 and the second steel truss 3, and the state is as Figure 2 shown. Thus, the first steel truss 2 and the second steel truss 3 are assembled and fixed through the assembly fixing cylinder 4. At the same time, the assembly stress column 8 is inside the butt joint of the first steel truss 2 and the second steel truss 3. Thus, the butt joint of the first steel truss 2 and the second steel truss 3 is strengthened through the assembly stress column 8, and the state is as Figure 2 shown. When, as Figure 1 shown, the first steel truss 2 and the second steel truss 3 are disassembled, the rotary adjustment cylinder 5 is rotated by a tool to be thread-engaged with the first steel truss 2, so that the rotary adjustment cylinder 5 descends through thread engagement, and the rotary adjustment cylinder 5 drives the moving bearing cylinder 6 to descend synchronously through the bearing. The fixed synchronous column 7 is driven to descend synchronously through the moving bearing cylinder 6, and the assembly stress column 8 is driven to descend synchronously through the fixed synchronous column 7, so that the assembly stress column 8 descends and disengages from the inside of the cylindrical rod of the second steel truss 3. Then, the assembly fixing cylinder 4 is rotated by a tool to be thread-engaged with the first steel truss 2 and the second steel truss 3, so that the assembly fixing cylinder 4 descends and disengages from the inside of the annular groove of the second steel truss 3 through thread engagement, and the state is as Figure 4 shown. Thus, the disassembly of the first steel truss 2 and the second steel truss 3 is realized. On the contrary, the operation is the assembly and fixing operation of the first steel truss 2 and the second steel truss 3.
[0032] Embodiment 2:
[0033] The difference from Embodiment 1 is that the regular hexagonal groove of the fixed synchronous column 7 can also be set as a regular heptagonal groove. Thus, the fixed synchronous column 7 needs to be rotated by a special tool that cooperates with the regular heptagonal groove, preventing non-staff from rotating and disassembling the fixed synchronous column 7.
[0034] Embodiment 3:
[0035] The difference from Embodiment 1 is that the inner end face of the fixed synchronous column 7 can also be set as a frosted surface. Thus, the friction between the inner end face of the fixed synchronous column 7 and the assembly stress column 8 is increased, preventing the fixed synchronous column 7 from rotating and loosening.
