Tooth-shaped connection node of steel structure

Abstract

The invention relates to a tooth-shaped connection node of a steel structure. The integral shape of the connection node is consistent to the connecting part of the steel structure to be connected; the connection node comprises two or more than two parallel continuous teeth and screw-thread cylindrical pins, wherein the teeth are in rectangular shapes, the concave parts and the convex parts of the teeth are same in width or the concave parts are slightly wider than the convex parts, the teeth are provided with two or more than two cylindrical holes which are parallel to a connecting end surface and penetrated by the teeth in a direction perpendicular to teeth shapes, and the cylindrical holes are provided with screw threads on head ends or tail ends; the screw-thread cylindrical pins are the same as the cylindrical holes in number and matched with the cylindrical holes; the depths of the teeth are larger than the diameters of the cylindrical holes; and the cylindrical holes are arranged on the intermediate positions of the teeth. The invention has the advantages of higher strength of the connection node, material saving, convenience for installation, high accuracy, beautiful appearance, structural space saving, and the like, can be widely used for a light steel combined type house, a module type multi-high building and the filed of convenient mechanical structure installation; and in the invention, high consistency of parts is achieved, and therefore, the industrial production level of a relevant industry and the value, i.e. quality and the like, of a product can be enhanced.

Description

technical field [0001] The invention relates to a connection method, in particular to a connection node of a steel structure building, and belongs to the technical field of building structures. Background technique [0002] With the development and progress of science and technology, a large number of multi-high-rise steel structure buildings have emerged, and various complex, flexible, high-end and beautiful buildings have also emerged. The steel structure connection node is a very important link as the link between the steel structure members to form a structure. The traditional connection method is to add welding connection plates to the connection parts, and then use high-strength bolts to connect, but this connection method is difficult to process and accurate. It is low in height, inconvenient to install, protruding connecting plate after installation, which wastes space; and the connecting parts are not neat, especially when these connecting nodes are directly used as...
