Steel structure joint connection device and manufacturing method thereof

Abstract

The invention provides a steel structure joint connection device and a manufacturing method thereof, and belongs to the field of steel structures. The problem that existing steel structure joints cannot be connected in a hidden mode is solved. The steel structure joint connection device is used for connecting six hollow steel pipes, a connection device comprises six connection parts, connection parts include outer connection pipes, inner join pipes, outer join pipes and inner connection pipes, connection boxes are arranged between outer connection pipes and inner connection pipes, the connection device further comprises baffles fixed on the inner walls of the top ends of the outer connection pipes, the bottom faces of the baffles abut against the top ends of the inner connection pipes in a sealing mode, grout-venting holes are formed in the baffles, any baffle is provided with a grouting opening, concrete mortar is poured into the connection parts through the grouting openings, and the six hollow steel pipes correspondingly sleeve six outer connection pipes in a matched mode and are fixed through fasteners. According to the steel structure joint connection device, the six hollow steel pipes can be connected in a high-intensive hidden mode.

Description

technical field [0001] The invention belongs to the technical field of steel structures, and relates to a steel structure node connecting device and a manufacturing method thereof. Background technique [0002] It is a common steel connection structure to connect six hollow steel pipes two by two vertically to form joints. The traditional method is to cut the ends of the steel pipes into shapes that fit each other, and then connect them sequentially through fasteners. However, this connection method forms The node strength is low; [0003] The existing application number is 201820600848.1, which is a Chinese utility model patent named "Aluminum alloy house ridge connection node". The overall expansion of the node will affect the connection between the node and other steel structures. Therefore, it is necessary to design a connecting device that is not only hidden inside the node, but also can connect several steel pipes with high strength. Contents of the invention [00...
