Background
With the continuous progress of our society, the steel yield of our country is stable in the world first, and the steel for the construction industry is rapidly developed. The steel structure building becomes an important component of the building in China, becomes a steel frame-shear wall (core tube) structure system, is more and more used in high-rise buildings due to outstanding advantages, the shear wall is used as an important component of the system, a concrete shear wall, a steel plate shear wall and the like can be adopted, and great attention is paid to the exploration of the steel plate shear wall along with the development and scientific progress of times. The steel plate shear wall system is a structural form for researching hot door as a structural system with excellent wind resistance and earthquake resistance, and has good application in high-rise building structures. The method has the advantages of high initial lateral stiffness, high shear bearing capacity after buckling, high energy consumption capacity, high ductility and the like, and provides a good lateral force resistant structural system for a multi-story and high-rise steel structure. Many engineering applications show that the high-rise building adopting the steel frame-steel plate shear wall has the advantages of short construction period and good wind and earthquake resistance, is a high-rise building lateral force resistant structure system with good development prospect, is an ideal choice for earthquake resistance reinforcement of old buildings, particularly buildings in high-intensity earthquake areas, and can be increasingly applied to engineering structures.
The shear wall has a large integral area, so that integral buckling is easy to occur under the action of vertical load and horizontal load, and the bearing capacity is lost; in addition, in double-deck steel sheet shear force wall, the connected mode between two steel sheets has the stud to connect, and the batten board is connected, and split bolt connects, but these modes do not all make and realize effectual connection between two steel sheets, bear vertical load and horizontal load in-process, lead to two steel sheets extremely easily and the concrete between be connected inefficacy, be the wall body and lose the bearing capacity.
In order to overcome the problems, the patent provides the assembled double-layer steel plate combined shear wall based on the concept of improving the elastic shear buckling load of the shear wall and the shear bearing capacity of the shear wall. The buckling deformation of the steel plates towards the outer side direction can be limited by the H-shaped part and the box-shaped part through the two outer steel plates in a pulling mode, concrete is poured into a cavity formed by the H-shaped part and the box-shaped part, the buckling deformation of the steel plates towards the inner side direction can be limited, the H-shaped part and the box-shaped part are not required to be welded and are not required to be screwed, the H-shaped part and the box-shaped part are completely connected together in an assembling mode, the restraint force is provided by means of interaction among all components, the whole wall is installed more quickly, the arrangement mode is more flexible.
Disclosure of Invention
The invention provides an assembled double-layer steel plate combined shear wall, and belongs to the field of structural engineering. The buckling deformation of the outer steel plate in the outward direction is limited through the pulling and connecting effect of the I-shaped piece and the box-shaped piece, the buckling deformation of the outer steel plate in the inward direction is limited through the filled concrete, and the integral bearing capacity of the wall body is improved.
In order to achieve the purpose, the invention adopts the following technical means:
the combined shear wall comprises an outer steel plate I, an outer steel plate II, a plurality of box-shaped parts, I-shaped parts with the same number and filled concrete; the I-shaped part is welded on the outer side steel plate I, the box-shaped part is welded on the outer side steel plate II, then the I-shaped part and the box-shaped part are assembled in an insertion mode, and concrete is poured in a cavity defined by the outer side steel plate, the I-shaped part and the box-shaped part to form the assembled double-layer steel plate combined shear wall.
The advantages of the patent are mainly shown in the following aspects:
1. in the double-layer steel plate shear wall, the connection between two layers of steel plates inside is always difficult to solve, and by welding a box-shaped part and an I-shaped part on the two steel plates respectively, on one hand, the connection mode of the inner part and the edge part is effectively ensured to be consistent, and the local wall body damage caused by a connected weak area can not occur in the stress process; on the other hand, since the connecting members are welded to both outer steel plates, they are connected by mechanical engagement force between the connecting members without additional welding or bolting.
2. The outer steel plate interacts with the inner box-shaped piece and the I-shaped piece, so that the overall bearing capacity of the wall body is improved. On one hand, in the process of bearing pressure or shearing force, the two outer steel plates are easy to bend and lose stability in a single wave mode, and the two outer steel plates are connected through the box-shaped part and the I-shaped part in a pulling mode, so that the outward bulging deformation of the steel plates can be limited. On the other hand, the box-shaped part and the I-shaped part can also serve as core stress members, the outer steel plate plays a role in connecting the connecting pieces to form a multiple bending side stress resisting member, the effect similar to embedding steel ribs in a wall body is achieved, and the side stress resisting bearing capacity and the compression resisting bearing capacity of the wall body are improved.
3. The integrally poured concrete can improve the compression and shear bearing capacity of the steel plate composite shear wall and can restrain the buckling deformation of the outer steel plate; meanwhile, the outer steel plate provides lateral restraint for the filled concrete, so that the filled concrete is in a bidirectional compression state, the compression resistance of the concrete is improved, and the development of concrete cracks is slowed down. The bilateral steel plates can be used as concrete templates, so that a formwork supporting procedure is omitted, the construction period is shortened, and the concrete is restrained by the steel plates and does not have the risk of falling even if being crushed.
4. This patent has very big partly work to accomplish in the factory in the work progress, very big shortening construction period, the error that probably appears in the effectual field construction of having avoided has still alleviateed the environmental pollution of job site simultaneously.
