Problems solved by technology

[0008] However, there are accidents such as bolt breakage at the joint and joint breakage in the bolted connection; fatigue is sensitive to the full-welded connection, and the problem of low-temperature cold brittleness of the welded structure is more prominent, resulting in welding residual stress and deformation, which has an adverse effect on the structural work

Abstract

The step steel plate type node structure comprises a beam column, a bottom plate, a first step block and a second step block, the first step block is connected with the side wall of the beam column, and the first step block and the second step block are connected to the upper end face of the bottom plate after being matched in place. The node structure further comprises a lock plate and a clamping and locking device. The locking plates are arranged on the two sides of the first step block and the second step block. A plurality of wedge block structures are arranged at the ends, matched with the first step block and the second step block, of the lock plate, the butt joint position of the first step block and the second step block is in a step shape, and a plurality of clamping containing cavities matched with the wedge block structures are jointly formed after the first step block and the second step block are matched in place; the clamping and locking device is arranged between the locking plates on the two sides so that the locking plates can be locked on the two sides.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a node structure and a construction method based on a stepped steel plate type. Background technique [0002] With the large population gathering in modern cities and the rapid economic development, steel structures have many advantages, such as light weight, high strength, good seismic performance, large usable space for buildings, environmental protection and good comprehensive economic indicators; One of the common structural forms of high-rise building structures. The connection design method of beam-column joints plays a very important and key role in the safety of buildings. The force bearing hub in the steel frame structure is also the force transmission hub in the steel frame structure. [0003] The beam-column joint is the key to the success or failure of the steel frame structure engineering design. The connection methods that can be used for beam-co...
