A corrugated braided reticulated shell structure and its construction method

Abstract

Provided are a wavy woven latticed shell structure and a construction method thereof. A latticed shell is of a wavy woven frame structure and comprises wavy longitudinal main rods parallelly distributed at intervals, oblique main rods, auxiliary oblique main rods, longitudinal keels, oblique keels and auxiliary oblique keels, wherein the oblique main rods and the auxiliary oblique main rods crossly connected with the longitudinal main rods, tree-shaped columns are connected under wave trough positions of the latticed shell, and the wave trough positions of the latticed shell are communicated with the insides of the tree-shaped columns. The latticed shell is wholly annular, an inner ring and an outer ring of the latticed shell are correspondingly provided with an outer seal edge beam and aninner seal edge beam. During construction, the latticed shell is manufactured and spliced in a unit way, the latticed shell and the tree-shaped columns can also be separately manufactured and then are hoisted to form a complete latticed shell structure. By adopting the design of the wavy structure, the overall attractive appearance and ornamental value of the latticed shell structure are increased. In addition, the change of wave peaks and troughs of the latticed shell can effectively increase indoor local clearance height. By arranging tod pieces and constraints in the latticed shell structure, the structural integrality is improved.

Description

technical field [0001] The invention belongs to the field of space structure construction, and in particular relates to a wave-shaped braided reticulated shell structure and a construction method thereof. Background technique [0002] Since the space reticulated shell structure has the dual characteristics of a rod structure and a thin shell structure, it is widely used in the construction field, and because of the reasonable force distribution among the rods, it can adapt to a large space span. The traditional form of reticulated shell structure is mostly a plane structure or a circular tube cross-section. The structural style is relatively single, lacking architectural rhythm and aesthetic feeling; It is easy to cause instability problems; there is also the mutual-supporting reticulated shell structure, whose main form of force transmission is bending moment force, which has low material utilization efficiency and low structural redundancy; in addition, the long network T...

The traditional form of reticulated shell structure is mostly a plane structure or a circular tube cross-section. The structural style is relatively single, lacking architectural rhythm and aesthetic feeling; It is easy to cause instability problems; there is also the mutual-supporting reticulated shell structure, whose main form of force transmission is bending moment force, which has low material utilization efficiency and low structural redundancy; in addition, the long network The shell structure adopts welded ball joints for on-site positioning and installation. During the installation process, the measurement workload is heavy, the technical requirements for welding workers are high, and it is difficult to control the quality of the reticulated shell.
