An inverted triangular tube truss and its construction method

Abstract

The invention discloses an inverted triangular pipe truss, comprising a steel structure truss, a shuttle-type steel pipe column (1) supporting the steel structure truss, a shear key (2) of a concrete embedded part and a concrete embedded part. The steel structure truss is composed of multiple The pipe trusses are welded together, and the pipe trusses constituting the steel structure trusses include a plurality of pipe trusses A (3) parallel to each other and arranged in the longitudinal direction, and a plurality of pipe trusses B (4) arranged in the transverse direction. The upper end of ) is connected to the connection part of the pipe truss A (3) and the pipe truss B (4), and the lower end is connected to the shear key (2) of the concrete embedded part; the shuttle-shaped steel pipe column (1) is inclined to the inside of the steel structure truss. The construction method of the inverted triangular pipe truss is also disclosed. The beneficial effects of the invention are: a tall space system with large span and high height can be formed, the shuttle-type steel pipe column is used for better stability, the building is beautiful in shape, overall, light and elegant, and beautiful.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to an inverted triangular tube truss and a construction method thereof. Background technique [0002] The truss structure is a space steel structure product composed of multiple rods connected through nodes according to a certain grid form. Because it has the advantages of space force, light weight, high rigidity, and good seismic performance; the truss structure is usually a space structure composed of two-way or three-phase planar trusses, and there are also quadrangular inverted cone spaces composed of rods. result. The former is simple in construction and is suitable for the connection of nodes in various situations. [0003] The entrance hall of a commercial building generally has a large span. At present, the ceiling of a large-span hall is usually a steel-concrete composite cast-in-place structure. The steel-concrete composite cast-in-place structure has strong be...

Problems solved by technology

[0003] The entrance hall of a commercial building generally has a large span. At present, the ceiling of a large-span hall is usually a steel-concrete composite cast-in-place structure. The steel-concrete composite cast-in-place structure has strong bearing capacity, small size, strong impermeability, and corrosion resistance. Strong, good fire performance, etc., but high requirements for construction timing, low construction efficiency, long construction period, large project investment and other disadvantages
