Large-span trapezoidal space steel pipe truss concrete floor structure

A steel pipe truss, large-span technology, applied in the direction of load-bearing elongated structural components, structural elements, building components, etc., can solve the problem that lightweight roofs cannot guarantee the bearing capacity and stiffness requirements, and it is difficult to meet the mechanical properties, economical and economical. It can achieve the effect of rich body, easy pipeline crossing, and small amount of structural steel.

Abstract

Provided is a large-span trapezoidal space steel pipe truss concrete floor structure. The floor structure comprises a concrete floor slab and a large-span trapezoidal space steel pipe truss; and the concrete floor slab directly bearing floor load is arranged on T-shaped supports of three pipe upper chord members of the large-span trapezoidal space steel pipe truss. A basic unit of the large-span trapezoidal space steel pipe truss is an internode; each internode is composed of the three-pipe upper chord members, two-pipe lower chord members, quadrangular pyramid diagonal web members, upper chord horizontal members, and lower chord horizontal members; the cross section of the basic unit is in the shape of an inverted trapezoid arranged in a triangle; the large-span trapezoidal space steel pipe truss is formed by intersecting connection of steel pipe direct welding joints; and the concrete floor slab is an fabricated prefabricated slab or a steel-concrete composite floor slab. The large-span trapezoidal space steel pipe truss concrete floor structure is reasonable and simple in structure, clear in force transmission, convenient to install, free of floor slab secondary beams and spacetrusses, small in steel consumption, large in rigidity, high in bearing capacity, high in spanning capacity, good in comfort level, and excellent in mechanical property.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to a concrete floor structure with steel pipe trusses in a large-span trapezoidal space. Background technique [0002] In recent years, public buildings with long-span roofs have become more and more widespread, such as stadiums, exhibition centers, theaters, and industrial plants. The roof structure of this type of building has various forms, including: arches, plane trusses, three-dimensional trusses, grid frames, reticulated shells, string beams, and suspend domes. The roof enclosure structure mainly adopts light metal roofs or membrane materials, depending on Take the roof into consideration. However, for upper floors and roofs, due to the large live load, lightweight roofs cannot guarantee the bearing capacity and rigidity requirements, so concrete floors must be used instead. At the same time, the significant increase in the dead load and live load of the concret...
