technical field

The utility model relates to a shear wall structure, in particular to a method in which steel plates are placed on the outside of the wall to form a multi-cavity rectangular outsourcing steel plate shear wall, and concrete is poured in the cavity, which belongs to the field of construction engineering.

Background technique

Concrete has high compressive strength and a wide range of material sources. The compressive and tensile strengths of steel bars are the same and very large. The shear wall composed of concrete and steel bars can give full play to the material properties of concrete and steel bars, and is widely used in actual projects. Concrete shear walls have high rigidity and high compressive strength, and are one of the indispensable components in high-rise concrete structures. The codes currently issued in my country are "Code for Design of Concrete Structures", "Code for Seismic Design of Buildings", "Concrete Structures of High-Rise Buildings" "Technical Regulations" and so on have carried out detailed regulations on concrete shear walls.

For super-high-rise concrete structures and super-high-rise hybrid structures, the thickness of the bottom concrete shear wall gradually increases with the increase of height. Under rare earthquakes or even fortified earthquakes, the tensile stress exceeds the tensile limit of concrete, and the plasticity develops rapidly. Tension and compression or shear failure, so it is necessary to add steel reinforcement or built-in steel plate shear wall in the shear wall. At present, super high-rise concrete structures and super high-rise hybrid structures of various structural types need to add steel skeletons or built-in steel plates in part or all of the wall piers at the bottom.

The "Concrete Shear Wall" given by the invention patent application with the publication number CN 101824863A is characterized in that at least one module is arranged inside the shear wall, self-compacting concrete is poured outside the module, and the thickness of the self-compacting concrete on both sides of the module is Less than or equal to 45mm.

"A Composite Shear Wall" given by the invention patent application with the publication number CN103485441A is characterized in that it includes double-layer metal plates arranged in parallel, a hollow interlayer is formed between the double-layer metal plates, and inner concrete is uniformly arranged in the hollow interlayer The steel pipe is fixedly connected to the double-layer metal plate, and a top beam is arranged on the top of the double-layer metal plate, and the top beam fixes the top of the steel pipe.

The "shear wall" given by the utility model patent with the publication number CN 203403558U includes a wall (1) in which a reinforcement cage (2) and two intersecting steel ribs (3) are anchored. , the two steel ribs (3) are fixed with the reinforcement cage (2), and it is characterized in that: the inner surface and the outer surface of each steel rib (3) are fixed with a plurality of guide columns (4), located in the same steel A plurality of guide posts (4) on the same surface of the rib (3) are arranged in a row along the width bisector of the steel rib (3), and the guide post (4) in the middle of each row of guide posts (4) The guide posts (4) on both sides are long and short, the outer ends of each guide post (4) protrude from the concrete of the wall (1) and the outer ends of each guide post (4) are fixed with pull rings (5) , the pull ring (5) of each row of guide posts (4) is threaded with a tensioned stay cable (6); the anchor end of each stay cable (6) is anchored to the wall via a first sleeve (7) (1) In the concrete, the tension end of each cable (6) is anchored in the concrete of the wall (1) through a second casing (8).

Through the investigation and analysis of the existing super-high structures above 400m, the wall of the core tube in a certain range at the bottom is designed as a built-in single-layer steel plate shear wall or a built-in double-layer steel plate shear wall. These walls have good earthquake resistance and wind resistance, and the walls The thickness of the body is relatively thin, but the construction is very complicated, requiring a large number of formwork, on-site steel bar binding and welding work, and a large number of cracks in the concrete caused by the different reactions between the built-in steel plate and the concrete to the thermal effect, almost every project has been carried out. The on-site experiment of proportional built-in steel plate shear wall needs to invest a lot of manpower, material resources and financial resources.
