Construction method of hexagon screen drum structure

Abstract

The embodiment of the invention provides a construction method of a hexagon screen drum structure, relating to the technical field of engineering designs. The construction method of the hexagon screen drum structure comprises the following steps: corner parts and middle parts of the hexagon screen drum structure can be constructed, the constructing height of each layer of the corner parts and the middle parts is set to be the sum of a preset height and a reserved height of the layer, and the reserved height of the layer is the height making the layer sink and deform due to the self weight of a building where the hexagon screen drum structure is positioned after the building where the hexagon screen drum structure is positioned is constructed; the corner parts and the middle parts of a constructed hexagon screen drum structure can be connected through panel point constructions, and the panel point constructions are used for connecting the corner parts and the middle parts and satisfying a relative movement of the corner parts and the middle parts of the hexagon screen drum structure in a set distance range; and the corner parts and the middle parts of the hexagon screen drum structure can be rigidly connected through the panel point constructions after the building where the hexagon screen drum structure is positioned is constructed.

Description

technical field [0001] The invention relates to the technical field of engineering design, in particular to a construction method of a hexagonal mesh cylinder structure. Background technique [0002] As a structural force system, the hexagonal structure has better anti-lateral stiffness and anti-lateral load capacity compared with ordinary frame structures and cross-grid structures, and has a certain vertical load-bearing capacity and vertical stiffness. As a new structural form, the combined structure of hexagonal grid has been applied in the field of architecture. [0003] When the slanted columns at the corners of the hexagonal net tube structure have the same section as the slanted columns at the middle, the gravity load can be transmitted directly downward respectively. Under the action of horizontal load, the force of the slanted column at the corner is greater than that of the slanted column at the middle, so the section of the slanted column at the corner needs to b...

AI Technical Summary

Problems solved by technology

However, during the construction process of the hexagonal grid structure, the nodes of the hexagonal grid structure are rigidly connected. Due to the large cross-section of the oblique columns at the corners, part of the gravity load in the middle will pass through the bending direction of the horizontal beam. Corner shifts, such as figure 1 As shown (the direction of the arrow in the figure is the force transmission direction of gravity load), the force transmission of gravity load is not direct, which will increase the burden on the inclined column at the corner, which is not conducive to the overall safety of the structure
