Description

Technical Field

[0001] The invention relates to the technical field of tube trusses, and in particular to an inclined tube truss module, an inclined tube truss structure and an assembling method thereof. Background Art

[0002] The tube truss is a commonly used structural form in large-span steel structure roofs. Plane trusses and three-dimensional trusses are both common types of tube trusses. Both types can effectively bear various loads on the roof, including dead loads, live loads, snow loads, wind loads, etc. When using a plane truss, each truss is in the vertical plane. Whether it is a plane truss or a three-dimensional truss, each truss is arranged at a certain distance, and this distance is the span of the purlin. The force transmission path of the roof is: roof panel (corrugated steel plate, aluminum plate, etc.) → roof purlin → tube truss. For roofs of conventional shapes, the above-mentioned plane truss or three-dimensional truss has a better effect.

[0051] The horizontal thrusts generated by adjacent inclined tube truss modules 100 under vertical loads can also offset each other, and the horizontal thrusts of the side frame trusses 50 are resolved by the locally arranged longitudinal horizontal tie rods 60 and the gable columns 31 .

[0052] In this embodiment, the assembly method of the continuously changing inclined tube truss structure 200 specifically includes the following steps:
