Problems solved by technology

[0003] In order to solve the problem that the existing connection nodes in the prior art cannot satisfy the single-layer reticulated shell structure of the free-form surface, the welded ball joints need on-site welding construction, the construction cost is high and the construction quality is difficult to guarantee. The existing assembled semi-rigid joints are applied to the free-form surface The single-layer reticulated shell cannot meet the requirements of stiffness and universality at the same time, and then provides a space-assembled tooth-shaped node structure

Abstract

The invention provides a space assembly type tooth-type joint structure, and relates to a tooth type joint structure. Problems that assembly type connection joints in the prior art cannot meet requirements of free-form surface single-layer latticed shell structures, ball joints are required to be welded and constructed on site, construction cost is high, construction quality is difficult to guarantee, existing assembly type semi-rigid joints have obvious shortcomings when used in free-form surface single-layer latticed shells, and requirements of rigidity and universality cannot be simultaneously met well are solved. The space assembly type tooth-type joint structure comprises a hollow ball and a connecting assembly, wherein the connecting assembly comprises a middle lug plate, tooth-type bolts, a connecting rod end plate, a connecting rod, a nut and lug plate connecting side plates, wherein the lug plate connecting side plate is fixedly mounted on the connecting rod end plate; the connecting rod is fixedly mounted on the connecting rod end plate; the middle lug plate and the two lug plate connecting side plates are connected to one another through the tooth-type bolts; and the middle lug plate is fixedly mounted on an excircle surface of the hollow ball. The space assembly type tooth-type joint structure is used in the field of civil engineering buildings.

Description

technical field [0001] The invention relates to a tooth-shaped node structure, in particular to a space-assembled tooth-shaped node structure. Background technique [0002] The single-layer spherical reticulated shell has become a promising space structure form due to its advantages of reasonable force, economical materials, beautiful and diverse shapes, and ability to cover a large space. The single-layer reticulated shell with free-form surface as the main external form has gradually become a hot spot and trend in the field of architecture. This type of building can not only meet various requirements for use, but also bring a new vision to the public due to the flexibility of its shape design. Shocking, mostly used in theaters, exhibition venues, stadiums and other public facilities. Nodes are the key components of the spatial grid structure. At present, the commonly used joints in single-layer reticulated shells mainly include welded ball joints and assembled semi-rigid...
