Description
Technical Field
The patent relates to a double-deck steel sheet compound shear wall of hole wave web is opened to area horizontal formula, belongs to the structural engineering field.
Background
Along with the increasing height of buildings, horizontal load gradually replaces vertical load to become an important control factor in the design of high-rise buildings, and the traditional lateral force resisting member cannot meet the requirements of the high-rise buildings on energy consumption capacity and horizontal bearing capacity. The steel plate shear wall structure is a novel lateral force resistant structure system developed in the last 70 th century, and becomes a structure favored by many designers due to the extremely high bearing capacity, the stable energy consumption capacity and the good ductility.
The steel plate-concrete combined shear wall is a novel lateral force resisting system developed on the basis of the steel plate shear wall. The combined shear wall aims to form a member form with excellent comprehensive performance by utilizing the advantages of high steel plate bearing capacity, good ductility, quick construction, high rigidity of a concrete plate, good fire resistance and the like. The double-layer steel plate and concrete filled composite shear wall is one of steel plate-concrete composite shear walls. In the combined shear wall, concrete is positioned at a core position and is restrained by two steel plates; meanwhile, the core concrete can also play a role in preventing the steel plate from buckling too early. From the aspect of stress performance, the combined mode can exert the advantages of two materials, has very high compression bearing capacity and shear bearing capacity, and is particularly suitable for high-rise and super high-rise buildings.
At present, the existing double-layer steel plate composite shear wall uses stiffening plates as connecting members, and uses a plane steel bar truss as the connecting member to tie two outer steel plates. The two double-layer steel plate combined shear walls have the defects that the two connecting members divide the outer steel plate into vertical strip-shaped plate strips, so that the stress performance of the plate strip which is not stiffened by the connecting members is weaker than that of the plate strip stiffened by the connecting members; in addition, when the two combined shear walls are processed, connecting components need to be welded on the two whole outer steel plates, and the processing is very difficult.
In order to solve the defects of the steel plate composite shear wall, the patent provides the double-layer steel plate composite shear wall with the transverse open type opening corrugated web plate based on the concept of improving the shearing buckling load of the outer steel plate and strengthening the combination effect of the outer steel plate and the cast-in concrete. The steel plate composite shear wall adopts the corrugated web plates and the tie bars as connecting members, and divides two outer steel plates into a plurality of smaller parts, so that the steel plates are prevented from being bent integrally, and the bearing capacity of the steel plate composite shear wall is improved. Meanwhile, due to the application of the double-layer steel plate shear wall unit, the processing and the transportation of the component are more convenient, and much labor cost and mechanical cost can be saved.
Disclosure of Invention
The invention provides a double-layer steel plate composite shear wall with a transverse open type hole-opening corrugated web, and belongs to the field of structural engineering. The buckling constraint effect of connecting members in the existing combined shear wall of several types of double-layer steel plates on the double-layer steel plates is improved, and the problem that the processing and transportation difficulty of the double-layer steel plate shear wall members is high is solved; the method achieves the aims of reducing the processing difficulty of the double-layer steel plate composite shear wall as much as possible, reducing labor cost, mechanical cost and transportation cost and facilitating assembly.
In order to achieve the purpose, the invention adopts the following technical means:
the utility model provides a double-deck steel sheet compound shear wall of hole wave form web is opened to area horizontal formula, its characterized in that: the double-layer steel plate composite shear wall is composed of a double-layer steel plate shear wall formed by welding a plurality of steel plate shear wall units with holed corrugated webs and integrally poured concrete. The steel plate shear wall unit consists of two outer steel plates, a holed corrugated web plate with the same length as the outer steel plates and a plurality of tie bars; the corrugated web plates with holes in the steel plate shear wall units are respectively welded with the two transversely arranged outer steel plates to tie the two outer steel plates. The welding of the holed corrugated web and the two outer steel plates can be finished in a factory, the processing difficulty is small, and the method is greatly superior to the traditional double-layer steel plate shear wall in that the bolting or welding of connecting members is required between the two large outer steel plates, which is large in processing difficulty. The tie bars in the steel plate shear wall units are positioned at the wave troughs of the holed corrugated web and welded on the inner sides of the two outer steel plates to tie the two outer steel plates. The corrugated web and the tie bars are jointly used as connecting members, so that the two outer steel plates are divided into smaller areas, the out-of-plane rigidity of the double-layer steel plate shear wall can be improved, and the bearing capacity is improved. The steel plate shear wall units form a double-layer steel plate shear wall by welding outer steel plates; the direction of welding seams among the steel plate shear wall units is along the horizontal direction of the wall body; and after the double-layer steel plate shear wall is welded and formed, pouring concrete to form the double-layer steel plate composite shear wall with the transverse open-hole corrugated web.
The holed corrugated web plate in the steel plate shear wall unit is welded on the outer steel plate in the transverse steel plate shear wall unit in the middle, so that the central axis of the holed corrugated web plate is ensured to be superposed with the central axis of the transverse outer steel plate; round holes are formed in each folded plate of the holed corrugated web plate, so that steel is saved, and the integrity of cast-in concrete is guaranteed.
The steel plate shear wall unit provided by the invention is very flexible in application, and can be welded into a double-layer steel plate shear wall in a factory according to a traditional method and then transported to the site; the steel plate shear wall can be transported to a construction site according to actual conditions and then welded on site, and then the steel plate shear wall is assembled into the double-layer steel plate shear wall, so that the transportation is more convenient, and the transportation cost can be saved.
The advantages of the patent are mainly shown in the following aspects:
1. based on the concept of improving the elastic shear buckling load of the outer steel plates and the shear bearing capacity of the outer steel plates, a plurality of holed corrugated webs and tie bars are arranged between the two outer steel plates, so that the buckling deformation of the outer steel plates during shearing can be well restrained; as the connecting component, the arrangement of the holed corrugated web plate and the tie bars at the wave troughs can divide the two outer steel plates into smaller parts than the traditional stiffening plates and the traditional plane steel bar truss type connecting component, and the detail constraint can effectively improve the elastic shear buckling load and the shear bearing capacity of the double-layer steel plate shear wall.
2. As the connecting component, the corrugated web plate can not transmit axial force, so that the corrugated web plate can not bear when the wall is pressed and sheared, the function of pulling and connecting the steel plates on two sides is always realized, and the pressed bearing capacity and the sheared stable bearing capacity of the outer steel plate are effectively improved; if the flat plate connecting member is adopted, when the wall bears a lateral force, the flat plate connecting member is easy to be pressed and bent, the pulling effect on the steel plates on the two sides can be obviously reduced, and the stress of the steel plates on the outer side is not facilitated; in addition, the contact surface of the corrugated web connecting member and concrete is larger, and the bonding effect between the steel plate and the concrete can be enhanced.
3. Based on the concept of easy processing, transportation and assembly, the method adopts a cutting and assembling method to cut the double-layer steel plate shear wall into steel plate shear wall units; compared with the traditional processing method that the connecting members are welded on two large complete steel plates by the double-layer steel plate shear wall, the steel plate shear wall unit is easier to process and manufacture in a factory and is easier to transport than the traditional steel plate shear wall.
4. 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.
