Problems solved by technology
[0003] Due to the large overall area of the shear wall, under the action of vertical load and horizontal load, the overall buckling is prone to occur and the bearing capacity is lost; in addition, in the double-layer steel plate shear wall, the connection mode between the two steel plates has Stud connection, slab connection, and tension bolt connection, but these methods do not achieve effective connection between the two steel plates. In the process of bearing vertical loads and horizontal loads, it is very easy to cause the two steel plates and their contact with the concrete. The failure of the connection between the wall is the loss of bearing capacity

Embodiment Construction
[0017] Below in conjunction with accompanying drawing, the embodiment of this patent is described in detail.
[0018] Such as Figure 1~3 As shown, an assembled double-layer steel plate composite shear wall
[0019] Include the following components.
[0020] 1 - Outer steel plate one;
[0021] 2——outer steel plate two;
[0022] 3 - box-shaped parts;
[0023] 4——I-shaped parts;
[0024] 5 - Concrete.
[0025] Such as Figure 1~3 As shown, an assembled double-layer steel plate composite shear wall is characterized in that: the composite shear wall includes one (1) outer steel plate, two (2) outer steel plates, several box-shaped parts (3), the same number The I-shaped part (4) and the inner filling concrete (5); the I-shaped part (4) is welded on the outer steel plate one (1), the box-shaped part (3) is welded on the outer steel plate two (2), and then Assemble the box-shaped piece (3) and the I-shaped piece (4) in a plug-in manner, and pour concrete (5) into the outer s...

The invention relates to an assembly type dual-layer steel plate combined shear wall, and belongs to the field of structure engineering. Based on the theory of the improvement of shear wall elastic shear buckling loads and anti-shear bearing force thereof, a box-shaped part and an I part are creatively introduced into the dual-layer steel plate shear wall, the I part and the box-shaped part are not welded and are completely connected together in an assembly manner without bolts, constraint force is provided through the mutual effect between components, an outer side steel plate is obviously tied, outer side steel plate elastic shear buckling loads and anti-shear bearing force therefore can be effectively improved, in addition, the wall is filled with concrete, pressing and shear bearing force of the steel plate combined shear wall can be improved, buckling deforming of an outer side steel plate can be constraint, meanwhile, the outer side steel plate provides side constraint for internally filled concrete, and is in the dual-way pressure state, the concrete anti-press capacity is improved, and the concrete crack development can be relieved.
Description
technical field [0001] This patent relates to an assembled double-layer steel plate composite shear wall, which belongs to the field of structural engineering. Background technique [0002] With the continuous progress of our society, my country's steel output has ranked first in the world, and the steel used in the construction industry has also developed rapidly. Steel structure buildings have become an important part of my country's buildings, and steel frame-shear wall (core tube) structure system is more and more used in high-rise buildings due to its outstanding advantages. Shear wall is an important part of the system Components can be concrete shear walls, steel plate shear walls, etc. With the development of the times and scientific progress, the exploration of steel plate shear walls has received great attention. As a structural system with excellent wind resistance and earthquake resistance, the steel plate shear wall system has always been a popular structural fo...
