Space composite truss structure and building

Abstract

The invention discloses a space composite truss structure and a building. The space composite truss structure comprises an upper chord beam and slab structure, a lower chord structure, and a verticalweb member, wherein the upper chord beam and slab structure comprises an upper chord plate and an upper chord beam, the upper chord beam is arranged below the upper chord plate, and the upper chord beam is fixedly connected to the upper chord plate; the lower chord structure comprises a plurality of first lower chords and a plurality of second lower chords, the plurality of first lower chords arearranged in parallel in a long-span direction of the upper chord plate, the plurality of second lower chords are arranged in parallel in a short-span direction of the upper chord plate, and the long-span direction is orthogonal to the short-span direction; and the vertical web member is located between the lower chord structure and the upper chord beam and slab structure, the upper end of the vertical web member is connected to the upper chord beam, and the lower end of the vertical web member is connected to the lower chord structure. By adopting the space composite truss structure, comparedwith a solid web girder structure, an overall structure thickness can be effectively reduced while the bearing capacity is guaranteed.

Description

technical field [0001] The invention relates to the field of construction, in particular to a space combined truss structure and construction. Background technique [0002] With economic development and population growth, my country's land resources are becoming more and more severe. In order to save land, most buildings often adopt site elevation measures. [0003] Taking the school as an example, when the school sports field is raised, public places such as swimming pools, indoor basketball courts, canteens, and lecture halls can be set up in the bottom space formed by the raised sports field. Considering the functions of these public places, the bottom space Most of them were unable to set up supporting columns, thus forming a large-span structure. It has been found in practice that the existing long-span structures are usually prestressed concrete structures of solid web beams, steel concrete structures or steel structures, and the thickness of solid web beam structures...

Problems solved by technology

[0003] Taking the school as an example, when the school sports field is raised, public places such as swimming pools, indoor basketball courts, canteens, and lecture halls can be set up in the bottom space formed by the raised sports field. Considering the functions of these public places, the bottom space Most of the Zhongda could not set up supporting columns, thus forming a large-span structure

In practice, it has been found that the existing long-span structures are usually prestressed concrete structures of solid web beams, steel concrete structures or steel structures, and the thickness of solid web beam structures is usually relatively large. Under the condition of ensuring the height of the indoor ceiling, the roof of the sports field The lifting height tends to increase, which is not conducive to the evacuation of personnel on the sports field
