Abstract

The invention relates to a latticed-shell structure, in particular to a single-layered latticed-shell structure, more particularly, a node structure of a rigid single-layered latticed-shell structure, and belongs to the technical field of roof buildings. The node structure is characterized by comprising six hollow rod pieces (3) welded and fixed with seal plates (2), and the welding angle is adjustable. The node structure further comprises a bolt drum (1) adopting a hollow cylindrical structure, wherein a detachable cover plate (101) is arranged on at least one end surface of the bolt drum (1); six groups of bolt holes are uniformly distributed in the circumferential direction of the bolt drum (1); the seal plates (2) welded with the hollow rod pieces (3) are in bolted connection with the bolt drum (1) through the bolt holes; and the bolt drum (1) is further provided with an axial bolt (4) through which the cover plate (101) is in bolted connection with the main body of the bolt drum (1).

Description

technical field

[0001] The invention relates to a reticulated shell structure, in particular to a single-layer reticulated shell structure, more specifically, a node structure of a rigid single-layer reticulated shell structure, and belongs to the technical field of roof construction. Background technique

[0002] The reticulated shell structure is a space bar structure similar to the flat grid structure. It is based on the bar, forms a grid according to certain rules, and is a space frame arranged according to the shell structure. It has both the properties of a rod system and a housing. The characteristic of its force transmission is mainly to transmit force point by point through the tension, pressure or shear force in two directions in the shell. This structure is a spatial structure that has attracted much attention at home and abroad and has broad development prospects. Compared with the steel structure, the reticulated shell structure has the characteristics of ligh...
