Connecting joint for beam, column and inclined strut of box section of boiler steel frame and construction method thereof

Abstract

The invention relates to a connecting joint for a beam, a column and an inclined strut of a box section of a boiler steel frame and a construction method of the connecting joint. The connecting joint comprises a joint plate, a column end plate, a beam end plate and a connecting end plate, wherein the joint plate is fixed with the inclined strut by welding; the column end plate is fixed on the joint plate by welding, and is connected with a column bolt; the beam end plate is fixed on the joint plate by welding, and is connected with a beam bolt; and the connecting end plate is fixed on the beam by welding, and is connected with the column bolt. The construction method comprises the following steps of: welding the joint plate, the column end plate and the beam end plate, and connecting the column end plate and the beam end plate with bolts; and performing welding and bolt connection on the connecting end plate. According to the invention, the joint size is reduced greatly, the requirements of other transportation tools are met, and the transportation cost is reduced.

Description

technical field [0001] The invention relates to a steel frame structure in the technical field of construction engineering, in particular to a connection node of a box-section beam, a column and a brace of a boiler steel frame, and also relates to a construction method of the connection node. Background technique [0002] The steel structure is an overall structure formed by connecting steel components through certain nodes. The nodes should have sufficient strength, stiffness and ductility to ensure the correct position of the connected components, meet the load-bearing and service requirements, and ensure the integrity of the structure in use. . In steel structure design, joint design is an important link, which is related to the safety and reliability of the overall structure. Reasonable joint design methods can improve the economic benefits of the entire structure design. In engineering, the processing and installation of node connections are also complicated and labor-...
