Joint drum structure for connecting steel structural part

Abstract

The invention relates to a joint structure, in particular to a joint structure of a single-layer reticulated shell structure, more particularly, is a joint drum structure for connecting a steel structural part, and belongs to the technical field of roof building. A bolt drum joint structure of a rigid single-layer reticulated shell structure is characterized by comprising a bolt drum (1) and six hollow rod pieces (3), wherein the bolt drum (1) is of a hollow cylinder structure; detachable cover plates (101) are arranged on the two end surfaces of the bolt drum; six groups of bolt holes are uniformly distributed in the circumferential direction of the bolt drum (1); the angle of the tangent plane of each hollow rod piece (3) can be adjusted; each hollow rod piece (3) is welded and fixed with a sealing plate (2); a group of bolt holes are formed in each sealing plate (2); the six hollow rod pieces (3) are in bolted connection with the bolt drum (1) through the bolt holes after being welded and fixed with the sealing plates (2).

Description

technical field [0001] The invention relates to a node structure, in particular to a node structure of a single-layer reticulated shell structure, more specifically, a node drum structure connecting steel structural parts, 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 light weig...

Problems solved by technology

[0005] The actual technical problem to be solved in the present invention is: adopt the node structure of the rigid single-layer reticulated shell structure in the way of direct welding between the rods and the rods, because in the actual connection, the angle between the rods needs to be according to the reticulated shell The actual shape of the structure is adjusted. It is difficult to ensure the required connection angle between the rods and rods by welding in advance, so it is impossible to weld them on the ground in advance and then hoist them to the roof. When the building needs to be capped, the welder climbs onto the net For the shell structure, it is very dangerous to weld it in the air, and it requires high skills for the welding workers. After the welding is completed, the rods will not match the rods, which is not accurate enough. At the same time, it is necessary to wait for the height of the building to be capped. The installation of reticulated shell structure can only be carried out later, and the construction progress is relatively slow
