Problems solved by technology

[0002] In the partition wall system used for steel structures, the conventional partition wall material adopts lightweight masonry, and the masonry partition wall blocks are made of mortar, and its integrity, stability, and bearing capacity are poor
Under certain conditions, core-filled masonry will be used, and the structure of the core-filled masonry joints is complicated, the construction process is complicated, and the quality is difficult to guarantee
In addition, in the industrial factory building, the process system needs to arrange embedded parts on the partition wall, but the masonry partition wall cannot be pre-embedded in advance, and only post-embedded parts can be used, which is not economical and the bearing capacity of the embedded parts is limited; when the factory building When there are high seismic requirements, the rear embedded parts cannot be used in the masonry partition wall, which is not convenient for the layout of the process system, such as in the steel structure workshop of the nuclear power plant
The steel structure has large deformation during earthquakes, good ductility, and good seismic performance. However, the connection nodes between the conventional masonry partition wall and the steel structure cannot effectively guarantee the large deformation and energy consumption of the steel structure. Unreasonable connection nodes may cause earthquakes. When the steel structure is torsion, it is extremely unfavorable to the force of the steel structure

Abstract

The invention discloses a concrete partition wall system for a steel structure, comprising a cast-in-place concrete partition wall and a connection node part between the cast-in-place concrete partition wall and the steel structure; the connection node includes a connection node at the bottom of the partition wall, and the partition wall The nodes are connected at the top of the wall, and the nodes are connected at the sides of the partition wall. The partition wall is a cast-in-place concrete component, the bottom is a fixed support, the top is a hinged support, and both sides are flexibly connected with the main steel structure. The partition wall is constructed after the main steel structure is completed. The partition wall system of the present invention has reasonable connection nodes around the partition wall, reasonable stress on the steel structure, good seismic performance of the partition wall itself, and at the same time ensures the coordination of seismic deformation with the main steel structure; it is convenient to arrange embedded parts on the wall , It is convenient for the layout of the process system, which solves the problem of difficulty in arranging embedded parts in traditional masonry partition walls, and at the same time improves the economy; post-casting of partition walls does not affect the construction progress of the main steel structure, and can effectively shorten the construction period.
