Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated building truss technology, and in particular to a prefabricated building truss. Background Technology
[0002] Architectural trusses are common load-bearing structures widely used in bridges, building roofs, and large-span structures. Their name derives from the fundamental characteristics of truss structures: trusses are typically composed of multiple straight members connected at nodes to form polygonal units, distributing and transferring loads. Truss structures utilize the tension and compression characteristics of their members, achieving efficient material utilization and excellent load-bearing capacity through rational mechanical design. Compared to traditional beam structures, trusses can significantly reduce structural weight while maintaining high strength, making them particularly suitable for large-span, high-rise, and other building applications requiring reduced structural weight. Traditional truss installation methods often rely on fixed connections, lacking flexible adjustment mechanisms. This makes rapid adjustments during on-site installation difficult, requiring high installation precision. Incorrect installation often necessitates readjustment or disassembly, increasing construction complexity and time. Furthermore, traditional methods commonly employ irreversible connections such as welding, hindering subsequent disassembly and recycling, failing to meet modern building requirements for environmental protection and resource reuse, necessitating improvements.

[0005] Preferably, the turntable is rotatably connected to the mounting block, and the bolt is threadedly connected to the mounting bracket A. Here, the turntable allows the rotating rod to be locked in a suitable position, while the bolt allows the mounting block to be locked and limited at any position on the surface of the mounting bracket A.
[0006] Preferably, the turntable is rotatably connected to the connecting block, and the screw is threadedly connected to the turntable. Here, the threaded connection between the screw and the turntable allows the turntable to be locked onto the surface of the mounting block, thereby limiting the rotation rod to a suitable angle.
[0007] Preferably, the rotating head and the rotating block are rotatably connected via bearings, and the lead screw and the rotating rod are threaded together. Here, by rotating the lead screw driven by the rotating head, the distance between the rotating rod and the rotating block can be controlled, thereby controlling the installation height and position.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0011] 1. In this utility model, by designing sliding and threaded connection structures on mounting bracket A and mounting bracket B, the rapid installation and efficient fixing of the building truss are achieved, reducing the requirements for on-site installation accuracy.

[0022] Please see Figure 1-4This utility model provides a technical solution: a prefabricated building truss, including a mounting frame A1 and a mounting frame B2. The surface of the mounting frame A1 is slidably connected to a mounting block 3, and the mounting block 3 is internally threaded with a bolt 4. The surface of the mounting frame B2 is fixedly mounted with a fixing block 5, the lower surface of the fixing block 5 is rotatably connected to a rotating block 6, the upper surface of the mounting block 3 is rotatably connected to a rotating rod 7, the bottom end of the rotating rod 7 is fixedly mounted with a turntable 8, the side of the mounting block 3 is fixedly mounted with a connecting block 9, the internal thread of the connecting block 9 is connected with a screw 10, the lower surface of the rotating block 6 is rotatably connected to a rotating head 11, and the lower surface of the rotating head 11 is fixedly mounted with a lead screw 12. This truss design allows for a sliding connection between the mounting frames A1 and B2. The combination of mounting block 3, bolt 4, and fixing block 5 ensures stable connections between components. The adjustability of rotating rod 7 and turntable 8 ensures structural flexibility, facilitating on-site installation and adjustment. Turntable 8 is rotatably connected to mounting block 3, and bolt 4 is threadedly connected to mounting bracket A1. This rotatable connection between turntable 8 and mounting block 3 allows the truss to be adjusted in different directions, enhancing the flexibility of the building structure during installation and adapting to different angle requirements. Turntable 8 is rotatably connected to connecting block 9, and screw 10 is threadedly connected to turntable 8. This design allows for flexible adjustment of the spacing between connecting block 9 and turntable 8, further improving the operability and robustness of the truss assembly during actual installation. Rotating head 11 is rotatably connected to rotating block 6 via bearings, and lead screw 12 is threadedly connected to rotating rod 7.
