Special-face reticulated shell and structural system combining same with pulling cable

Abstract

The invention discloses a special-face reticulated shell and a structural system combining the same with a pulling cable. A plurality of inner layer components and outer layer components are included.A plurality of connection structures are arranged on the outer sides of the inner layer components in the length direction of the inner layer components, wherein the inner layer components are provided with continuous bent structures, and all the inner layer components are arranged in line. The outer layer components are installed on the outer sides of all the inner layer components in line through the connection structures. The structural system is formed by combining the special-face reticulated shell and the pulling cable. The special-face reticulated shell provided by the invention can give consideration to the needs of both architectural modeling and structure stress, and the structural system formed by combining the special-face reticulated shell and the pulling cable is adopted andhas high progressive collapse resistance.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a reticulated shell with different planes and a structural system combined with cables. Background technique [0002] Reticulated shell is a kind of spatial rod system structure similar to flat grid frame. It is based on rods and forms a grid according to certain rules. The space frame is arranged according to the shell structure, which has the properties of both rod system and shell. The characteristic of force transmission is mainly point-by-point force transmission through the tension, pressure or shear force in two directions in the shell. Compared with the flat grid frame, the reticulated shell has good mechanical performance, high rigidity, small dead weight, and less steel consumption. It is a better structural type suitable for medium and large-span building roofs. [0003] Existing reticulated shells are generally connected by independent straight membe...

AI Technical Summary

Problems solved by technology

[0003] Existing reticulated shells are generally connected by independent straight members or single curved members. These members only have curvature in one direction, and the formed reticulated shells are mostly cylindrical reticulated shells, spherical reticulated shells or hyperbolic parabolic nets. Shells can be divided into single-layer reticulated shells (orthogonal grids with one-way inclined bars, orthogonal grids with crossed inclined bars, joint square grids, and three-way grids) and double-layer reticulated shells. Large category, double-layer reticulated shell refers to the layout of different grids according to the type of flat grid. The single-layer reticulated shell in the existing reticulated shell has a single shape structure and poor structural stability; while the inner layer and outer layer of the double-layer reticulated shell There are many steel beams connected between layers, which lack aesthetic feeling, or reduce the use of steel beams, but there are problems of insufficient out-of-plane rigidity and low safety of the reticulated shell structure; There are the above problems, that is, the problem of not being able to have both shape and connection strength
