Reverse triangular pipe truss and construction method of reverse triangular pipe truss

Abstract

The invention discloses a reverse triangular pipe truss, which comprises a steel structure truss, shuttle-shaped steel pipe posts (1), concrete embedded element shear keys (2) and concrete embedded elements, wherein the shuttle-shaped steel pipe posts (1) are used for supporting the steel structure truss; the steel structure truss is formed by welding a plurality of pipe trusses; the pipe trusses forming the steel structure truss comprise a plurality of mutually parallel pipe trusses A (3) arranged in the longitudinal direction and a plurality of pipe trusses B (4) arranged in the transverse direction; the upper end of each shuttle-shaped steel pipe post (1) is connected with a connecting part of the corresponding pipe truss A (3) and the corresponding pipe truss B (4), and the lower end of each shuttle-shaped steel pipe post (1) is connected with the corresponding concrete embedded element shear key (2); and each shuttle-shaped steel pipe post (1) is inclined towards the inner side of the steel structure truss. The invention also discloses a construction method of the reverse triangular pipe truss. The reverse triangular pipe truss and the construction method of the reverse triangular pipe truss have the beneficial effects that a large-span great-height space system can be formed; the shuttle-shaped steel pipe posts are used, so that the stability is high; the building appearance is elegant; and the whole body is light, ingenious, graceful, attractive and elegant.

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
