Description

Technical Field

[0001] The utility model belongs to the technical field of building trusses, and in particular relates to an assembled building truss. Background Art

[0002] A building truss is a prefabricated component commonly used in building structures. It consists of multiple triangular units, which are connected together by connectors (such as bolts, welding or other mechanical connection methods) to form a stable three-dimensional structure. The truss structure can effectively disperse the load and transfer the load to the support point. It is suitable for large-span and heavy-load structural design. The truss structure has been widely used in modern buildings due to its efficient bearing capacity and economy. In the prior art, the truss unit is fixed by bolts or welded on site. The bolt fixing method requires a large number of bolts, and the assembly and disassembly work is large. Once the bolts become loose, it will affect the bearing effect of the truss. Although the welding method can ensure the stability of the connection, the subsequent disassembly of the steel truss requires separation by electric welding and cutting. The truss cannot be used again after welding and cutting, resulting in excessive construction costs. Utility Model Content

[0005] Furthermore, the truss frame, transverse truss beam and longitudinal truss beam are all composed of an upper chord beam rod, a lower chord beam rod and a supporting diagonal beam rod. The upper chord beam rod and the lower chord beam rod are arranged in parallel up and down, and the supporting diagonal beam rod is arranged between the upper chord beam rod and the lower chord beam rod.

[0006] Furthermore, the truss support units formed by splicing multiple groups of transverse truss beams and longitudinal truss beams are spliced ​​with each other through mortise and tenon structures to form a mesh support truss.
