Description
Technical Field
The patent relates to a double-deck steel sheet shear force wall of two hem groove steel mouth style of calligraphy drawties belongs to the structural engineering field.
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; and because of its large area, it is difficult to adapt to shear wall components of most structures for targeted mass production.
In order to overcome the problems, the patent provides the double-layer steel plate shear wall with the double-crimping groove steel notch-shaped drawknot based on the idea of improving the elastic shear buckling load of the shear wall and the shear bearing capacity of the shear wall. The steel plate shear wall is formed by welding a plurality of steel plate shear wall units with curled channel steel; the steel plate shear wall unit is formed by tying two outer steel plates through two curled-edge channel steel, and the buckling mode of the whole wall body can be changed due to the tying effect of the curled-edge channel steel, so that the whole buckling of the wall body is changed into local buckling between the curled-edge channel steel, and the whole bearing capacity is effectively improved. The shear wall unit is used to enable the installation of the whole wall to be quicker, the arrangement mode is more flexible, the construction is convenient and fast, and the quality is easy to guarantee.
Disclosure of Invention
The invention provides a double-layer steel plate shear wall with double-crimping groove steel notch-shaped drawknots, and belongs to the field of structural engineering. Two outside steel sheets are tied through two curled-edge channel steel to form a steel sheet shear wall element, and the shear wall unit is spliced to form an integral steel sheet shear wall, so that the integral bearing capacity is improved.
In order to achieve the purpose, the invention adopts the following technical means:
the double-side steel plate shear wall consists of a plurality of steel plate shear wall units with curled edge channel steel; the steel plate shear wall unit comprises an outer side steel plate I and an outer side steel plate II which are symmetrical front and back, a first curled-edge channel steel and a second curled-edge channel steel which are equal to the outer side steel plate, wherein a web plate of the first curled-edge channel steel is welded with the outer side steel plate I, a web plate of the second curled-edge channel steel is welded with the outer side steel plate II, the middle positions of the curled-edge channel steel and the outer side steel plate are guaranteed, the central axis of the curled-edge channel steel is guaranteed to be coincident with the central axis of the outer side steel plate, and then two flanges of the first curled-edge channel steel are welded with two flanges of the second curled-edge channel steel; the connection between each steel plate shear wall unit is formed by welding two corresponding outer steel plates. In order to ensure the connection between the curled channel steel and the outer steel plate, continuous welding is carried out at two edge positions of the curled channel steel by welding between the curled channel steel and the outer steel plate, intermittent holes are formed at the central axis position of a web plate of the curled channel steel, and plug welding is carried out at the holes.
The advantages of the patent are mainly shown in the following aspects:
1. in double-deck steel sheet shear force wall, the connection between the inside two-layer steel sheet is the difficult problem of solving always, and this patent has effectively guaranteed through setting up this component of steel sheet shear force wall unit that inside and marginal portion connected mode are unanimous, can not appear in the atress in-process because the local wall body that the weak area of connection leads to destroys.
2. Outside steel sheet and inside turn-up channel-section steel interact have improved the whole bearing capacity of wall body, and at the in-process that bears pressure or bear the shear force, single wave buckling instability takes place easily for two outside steel sheets, through two outside steel sheets of turn-up channel-section steel drawknot, can restrict the steel sheet and warp to the bulging of outside or the bucking of inboard warp, effectively promote outside steel sheet elasticity shearing buckling load and its anti-shear bearing capacity.
3. By adopting the design that the curled edge channel steel web plate is welded with the outer steel plate in a clinging manner, the lateral stiffness can be provided for the steel plate shear wall more effectively, and the force flow transmission of the shear wall is more definite; meanwhile, the curled channel steel web and the outer steel plate directly participate in the drawing and connecting action of the shear wall anti-side and the curled channel steel flange on the outer steel plate, so that the elastic shear buckling load of the outer steel plate and the shear resisting bearing capacity of the outer steel plate can be effectively improved; based on this, the width of the web plate of the curled channel steel can be obviously larger than the horizontal distance of the curled channel steel during design, so that the elastic buckling load of the plates among all the cells is close, and the economical efficiency of the steel plate shear wall is effectively improved.
4. In the steel plate shear wall unit, two hemming channel-section steels are connected together through the welding flange, form the square-shaped component, and it can act as core atress component, and the outside steel sheet plays the effect of connecting each hemming channel-section steel, constitutes multiple anti side force component that bends, reaches the effect of similar burying the reinforcing bar in the wall body, improves the anti side bearing capacity and the resistance to compression bearing capacity of wall body.
5. Novel steel sheet shear force wall arrangement mode is more nimble, because the area of wall body is great, and traditional steel sheet wall uses the steel sheet size great, and no matter transport or installation all have a lot of inconveniences. The steel plate shear wall units are spliced into the integral wall body on site in the form of steel plate shear wall units, so that the requirements of different sizes and forms can be met.
6. The size of the required component of the novel steel plate shear wall is single, and only two components of the outer steel plate and the curled edge channel steel with the same size are needed, so that the quantitative production in a factory is convenient.
7. 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.
