Problems solved by technology

The tensile and compressive ability of wood is good, but its bending resistance is poor. The span of modern public buildings is getting larger and larger. At the same time, because the strength of wood is smaller than that of steel, when the structural span is large, the cross-section of wooden components is often relatively large.

Embodiment

[0033] Such as Figure 1-7 As shown, a long-span steel-wood-cable hybrid structure system, the top of the system is a cross-diamond single-layer shell structure, and the middle area along the extension direction of the shell structure is mainly under pressure. According to the analysis of the internal force of the structure, the adopted structure It is a wooden reticulated shell, and both sides of the wooden reticulated shell 1 are connected to the steel reticulated shell 2, and the bending moment of the wooden reticulated shell 1 is smaller than that of the steel reticulated shell 2.

[0034] Since the current wood components are connected by metal connectors, it cannot meet the requirement of rigid connection for single-layer reticulated shells stipulated in the "Technical Regulations for Spatial Grids". The cable net support structure 3 is connected to the wooden reticulated shell 1 through the struts 4. By applying prestress to the cables, the vertical stiffness of the woo...

Abstract

The invention relates to a large-span steel-timber-cable hybrid-structure system. The large-span steel-timber-cable hybrid-structure system is characterized in that the top of the system is of a silo-shell structure, the middle area in the extending direction of the silo-shell structure is a timber reticulated shell (1), the two sides of the timber reticulated shell (1) are connected with steel reticulated shells (2), the bending moment of the timber reticulated shell (1) is smaller than the bending moment of the steel reticulated shells (2), and an intersecting-cable-net supporting structure (3) is arranged at the bottom of the timber reticulated shell (1). According to the large-span steel-timber-cable hybrid-structure system, compared with the prior art, the aesthetic requirements for an modern public building are met, structural internal force distribution is considered, and the positions with large bending moments adopt steel structures, so that the bending resistance is guaranteed; and the intersecting-cable-net supporting structure is arranged at the bottom of the timber reticulated shell, so that the safety degree of whole structure is enhanced, and through applying prestress on pull cables, the vertical rigidity of a timber structure can be enhanced.

Description

technical field [0001] The invention relates to a building structure, in particular to a large-span steel-wood-cable hybrid structure system. Background technique [0002] Because of its warm and natural characteristics, wood gives people a positive, happy and peaceful feeling. At the same time, wood is green and environmentally friendly, and has good durability. Therefore, it is more appropriate to use wood structures in large public buildings (such as swimming pools, gymnasiums, and exhibition halls). The tensile and compressive ability of wood is good, but its bending resistance is poor. The span of modern public buildings is getting larger and larger. At the same time, because the strength of wood is smaller than that of steel, when the structural span is large, the cross-section of wooden components is often relatively large. . Contents of the invention [0003] The object of the present invention is to provide a large-span steel-wood-cable hybrid structure system th...
