Description

A prefabricated profiled steel plate-concrete shear wall

technical field

The utility model relates to the field of building structures, in particular to an assembled profiled steel plate-concrete shear wall.

Background technique

In recent years, damage and deformation of shear walls caused by earthquakes and wind loads have occurred from time to time. Compared with the traditional cast-in-place concrete structure, the prefabricated concrete structure has the advantages of fast construction speed, less pollution, and saving labor costs. At present, various construction companies are vigorously developing the prefabricated concrete structure to promote the industrial upgrading of the construction industry.

The prefabricated concrete shear wall is one of the important components in the prefabricated concrete structure. It is a wall in a house or building that mainly bears horizontal and vertical loads caused by wind loads or earthquakes. It can prevent structural shearing (shearing) )destroy. The shear wall structure has high rigidity and good mechanical performance. It is the preferred structural form of high-rise residential buildings and one of the main structural forms of prefabricated buildings in my country. In the prefabricated concrete structure, the upper and lower wall pieces of the shear wall are connected as a whole by vertical steel bars. Therefore, the connection quality of the vertical steel bar directly determines the force and seismic performance of the prefabricated shear wall structure, which is the key factor affecting the shear wall. important factor in performance.

Utility model content

In order to solve the defects described above and ensure that the shear wall structure has sufficient strength, rigidity and stability in the horizontal and longitudinal directions, the utility model provides a prefabricated compression wall with simple structure, convenient construction, good overall performance and high strength. Steel plate-concrete shear wall.

In order to achieve the above object, the technical scheme adopted by the utility model is as follows:

A prefabricated profiled steel plate-concrete shear wall is formed by interconnecting a prefabricated wall and a metal base plate connected with circular steel pipes, wherein:

The metal bottom plate is provided with connecting grooves for connecting circular steel pipes and profiled steel plates, and the circular steel pipes are connected with the connecting grooves for circular steel pipes through threads;

The prefabricated wall is composed of a square steel pipe, a closed profiled steel plate and a concrete layer. The closed profiled steel plate arranged in the wall extends out of the concrete layer by a certain length, and bolt holes are distributed on the profiled steel plate extending out of the concrete part. After being inlaid with the profiled steel plate connection groove on the metal base plate, it is then connected by high-strength bolts; through the inlay of square steel pipes, circular steel pipes, the inlay of closed profiled steel plates and the profiled steel plates on the metal base plate, and high-strength bolts to achieve overall fixed connection .

The square steel pipes and round steel pipes are respectively hollow steel pipes.

Since the profiled steel plate of the prefabricated shear wall plays the role of connecting with the metal base plate, the profiled steel plate must have a certain strength and rigidity to ensure that the structural connection will not be damaged.

The beneficial effects of the utility model are: considering that the profiled steel plate has the characteristics of high strength and good shock resistance, the profiled steel plate is placed in the wall to increase the strength of the wall. At the same time, taking into account the shortcomings of this type of shear wall that are still insufficient in resisting horizontal and vertical loads, circular steel pipes and square steel pipes are added to the wall to further enhance its overall strength and greatly avoid deformation caused by steel plates. The resulting damage to the wall makes the profiled steel plate, round steel pipe, square steel pipe, and concrete layer inside the wall jointly stressed, thereby enhancing the overall strength of the shear wall.
