Installation method of combined joint with steel structure

Abstract

The invention provides an installation method of a combined joint with a steel structure, which belongs to the technical field of architectural construction. The installation method mainly comprises the following installation steps of: firstly, welding channel steel 4 additionally at a position on a steel column 1, which is connected with a truss and welding an inner baffle plate 5 at the positions of 80 to 150mm at the inner sides of the end parts of an upper chord 2 and a lower chord 3 of the truss respectively; and then, welding an end sealing plate 6 additionally at the edge of each inner baffle plate 5, welding connecting plates 7 at the lower parts of the end sealing plates 6 and then welding vertical stiffening ribs 8 at both sides of the connecting plates 7 and the end sealing plates 6. During installation, the connecting plates 7 and the channel steel 4 are directly connected by using high-strength bolts 9. By the invention, the combined joint mode of the inner baffle plates 5 and the vertical stiffening ribs 8 is adopted, perforations required by a traditional joint are cancelled, the upper chord and the lower chord of the truss and the wall of the steel column 1 do not need to be welded, the manufacturing process and the manufacturing cost are reduced, force transfer is more definite, the strength of the joint is increased, and the safety coefficient of the steel structure is enhanced.

Description

technical field [0001] The invention belongs to the field of building construction and relates to a steel structure installation method. Background technique [0002] In large-scale steel structure buildings, the installation method of the combined joints of steel pipes and steel pipe trusses is very important, which directly affects the safety and practicability of the steel structure. Generally, cross-bolt joints are used, that is, high-strength bolts pass through steel pipes and are installed on steel pipe trusses. Although this installation method is simple, it requires high machining accuracy for the length of the truss, and it is difficult to eliminate the accumulated construction errors. The installation is sensitive to temperature, and the installation cost is relatively high. In addition, holes must be opened in the column wall of the node area, which weakens the cross section of the steel pipe. It affects the structural stability of steel pipes and causes potentia...

Although this installation method is simple, it requires high machining accuracy for the length of the truss, and it is difficult to eliminate the accumulated construction errors. The installation is sensitive to temperature, and the installation cost is relatively high. In addition, holes must be opened in the column wall of the node area, which weakens the cross section of the steel pipe. Affect the structural stability of steel pipes and cause safety hazards, so it is not suitable for steel structure buildings with high safety and quality requirements
