Description
Technical Field
The invention belongs to the technical field of assembly type buildings, mainly relates to an assembly type reinforced concrete shear wall combined installation technology, and particularly relates to a reinforced concrete shear wall self-adaptive connection structure and a modular shear wall.
Background
At the present stage, the country requires the implementation of green and environment-friendly sustainable development, and the assembly type building can improve the operation mode, save a large amount of resources, has small environmental pollution and meets the requirements of the current social development. At present, in an assembly type building, a shear wall structure is one of very important lateral force resisting constructions, and the prefabrication and connection modes of the shear wall structure need to be mastered in an important way.
The connection modes of the existing-stage assembly type reinforced concrete shear wall structure comprise grouting sleeve connection, mechanical connection, welding, lap joint and the like, the grouting sleeve connection is used as one of the main connection modes of the assembly type shear wall, the connection needs very high precision, but in the construction process, the embedded quantity of sleeve inserted reinforcing steel bars is large, the inserted reinforcing steel bars are prone to being skewed or deviated during concrete vibration, large embedded errors are generated, and the sleeves can be deviated from the original positions due to mold expansion caused in the prefabricating process of the shear wall in a prefabricated part factory, and certain manufacturing errors can be generated; the reserved grouting sleeve and the inserted steel bar are staggered when the shear wall is installed due to the errors, so that the installation accuracy of the shear wall cannot meet the requirement. When a worker meets the condition, the inclined reinforcing steel bars are either inserted rigidly or transformed, and the reinforcing steel bars with larger deviation are directly cut off, and the methods are not preferable, so that the connection bearing capacity of the shear wall is reduced, and the construction progress is slowed down, so that the construction cost is increased.
At present, a prefabricated part factory can prefabricate shear walls with different sizes or various shapes, but for large-size shear walls, a large template is needed during prefabrication, and the prefabrication speed is low due to the limitation of production equipment; for the shear wall with the T-shaped section or the L-shaped section, due to the shape of the section, the embedded part is difficult to stabilize in the mold, and the embedded part is easy to deviate from the original position in the process of vibrating concrete, so that hole positions cannot be accurately aligned when the shear wall and the embedded part are installed; the shear wall with the special cross section shape needs more buffer materials to prevent the wall body from being damaged in the transportation process, so that the quality problem of the shear wall with the large size or the special cross section shape is easy to generate in the transportation process. When the shear wall with large size or special section shape is divided into small modules for prefabrication, the mold can be manufactured in a standardized manner, so that the prefabrication speed can be increased, and the standardization degree of the prefabrication of the shear wall is improved. The small module wall body can select the vehicle transportation of unidimensional not, and the transportation is more nimble, fixes the quality problems that small module wall body can effectively reduce the transportation on the way because of not hard up produced with steel cable or anchor clamps, can reduce the wall body and take place to damage the economic loss who causes in the transportation.
Therefore, a novel self-adaptive connection structure which has enough bearing capacity and a larger adjustment range and can be freely combined according to the connection part of the shear wall needs to be designed.
