Problems solved by technology

It overcomes the problems that general connection nodes require on-site welding to prolong the construction time, which is not conducive to on-site construction, and also solves the problem that the common connection nodes are affected by the design of adjacent auxiliary components due to the protrusion of the connected components such as ear plates, cover plates, and flange plates.

Embodiment Construction

[0027] The technical scheme of the present invention will be further described below in conjunction with the drawings.

[0028] The invention provides a jointing scheme for a closed-section steel pipe column without welded seam full bolts and less nodes protruding from connected components.

[0029] The node of the invention is composed of two connected closed-end section columns, an inner sleeve, an inner lining plate and bolts. Such as figure 1 - Image 6 As shown, where: 1 is the upper steel pipe column, 2 is the inner liner, 3 is the upper column fastening bolt, 4 is the lower column fastening bolt, 5 is the inner sleeve, 6 is the lower steel pipe column, 7 is the upper and lower For the bolt holes on the column, 8 is a groove section on the inner sleeve, and 9 is a bolt hole on the inner sleeve. The inner sleeve 5 is used as a splicing member to connect the lower steel pipe column 1 and the upper steel pipe column 6. The inner sleeve 5 is fastened to the lower steel pipe co...

Abstract

The invention belongs to the technical field of building steel structure node connection, and particularly relates to a closed-section member splicing node, which consists of an upper steel tube and a lower steel tube which are to be connected, a slotted inner sleeve, bolts and an inner lining plate. The node takes the slotted inner sleeve as a splicing member and the bolts as fasteners, and the inner lining plate can be used for increasing the frictional force of bolt friction-type connection. The problem that common connecting nodes are required to be welded on site is solved, the problem that the common connecting nodes are provided with end plates, ear plates and bolts protruding a connected member to influence the design and construction of adjacent members is solved, and the splicing node has good antiseismic energy dissipation performance. The node is easy and convenient to operate, high in construction speed, high in mounting accuracy and labor-saving, and has a wide application prospect.

Description

Technical field [0001] The invention belongs to the technical field of building steel structure node connection, and specifically relates to a steel pipe component connection node. Background technique [0002] Steel structure buildings have the characteristics of high strength, light weight, fast construction speed, good seismic performance and high degree of industrialization. Steel structural components form a structural system by connecting nodes. The choice of node form has a direct impact on the structural integrity, reliability, construction period, and the design and construction of auxiliary components. [0003] Steel structure nodes mainly realize the splicing and connection of beams, columns, supports and other components. The existing steel structure joints have various forms. According to the force transmission characteristics of the joints, they can be divided into rigid joints, hinge joints and semi-rigid joints. Connection methods include welded connection, bolt c...
