Abstract

The invention discloses an assembly type space structure C-type node device, relates to the field of civil engineering, and aims to solve the problem that existing single-layer latticed shell structures cannot satisfy rapid construction and large-stiffness rotation of assembly type steel structures simultaneously. The assembly type space structure C-type node device comprises rod pieces, a node cylinder and bolts, wherein the rod pieces take the axis of the node cylinder as the center and are evenly distributed outside the outer wall of the node cylinder in a radial manner, and the node connecting end surface of each rod piece is a cylindrical surface, closely contacted with the side wall of the node cylinder and fixedly connected with the side wall of the node cylinder through two bolts. According to the assembly type space structure C-type node device, each node component can be transported to a construction site after being prefabricated in a factory, the latticed shells can be directly assembled through high-strength bolts, site welding is not required, the construction speed is high, the construction difficulty and the construction cost are reduced, and the same node can be adapted to requirements of different rod piece forms and section sizes for connection; and compared with existing assembly type bolt-sphere nodes, the node is better in rotational stiffness. The assembly type space structure C-type node device is applied to the field of civil engineering.

Description

technical field [0001] The present invention relates to the field of civil engineering. Background technique [0002] The single-layer reticulated shell has become a promising space structure due to its reasonable force, economical materials, beautiful and diverse shapes, and can cover a large space. Nodes are a key component of the spatial grid structure. On the one hand, in the space structure, the steel consumption of the joint usually accounts for 20%-50% of the steel consumption of the whole structure; on the other hand, the joint stiffness is the main factor affecting the bearing capacity of the space grid structure. Although the welded ball joints in the existing space structure have high connection stiffness and good mechanical performance, the on-site construction is difficult and costly, and cannot meet the requirements of fast construction of prefabricated steel structures; while the existing bolted ball joints are constructed on site. It is convenient and can m...
