Assembly-type concrete shear wall structure system buckled and anchored through ring ribs

Abstract

The invention provides a building structure system which is formed by connecting prefabricated shear walls and composite floor slabs in a prefabricating and in-situ casting mode. Closed steel bar rings are arranged all around the outside of concrete of the shear walls in a protruding mode. When the system is used, closed hooping ribs or the closed steel bar rings which are used for connecting the shear walls and protrude out of the concrete are made to be staggered, steel bars are arranged in the closed hooping ribs or the closed steel bar rings in a penetrating mode for fixing, and then concreting connection is performed. Meanwhile, hidden beams can be prefabricated in the prefabricated shear walls. Thus, the phenomena that convex beams and convex columns appear indoors are greatly reduced; an outer wall maintenance structure is simple; through the combination of prefabricating and in-situ casting, the construction progress is greatly improved and the construction cost is lowered; tie bars used for fixing the distance between longitudinal steel bars and preventing the longitudinal steel bars from being stressed to be bent are arranged among the longitudinal steel bars, and therefore a whole building framework connecting structure is more stable.

Description

technical field [0001] The invention belongs to the technical field of buildings, and in particular relates to a prefabricated building body. Background technique [0002] It is estimated that by 2020, my country's urbanization level will reach about 57%, with a total urban population of 828 million. Facing the rapid development of urbanization, the demand for urban housing is increasing. [0003] While the housing construction market is developing rapidly, due to the design and construction technology constraints of the existing housing, it has been unable to meet the people's requirements for housing quantity and quality. [0004] (1) The construction speed of traditional houses is slow, which is not commensurate with the level of urbanization. [0005] The construction of standard floors in traditional residential buildings is relatively fast, and it takes 5 days per floor. In addition to the later decoration and decoration, it usually takes one or two years for a resid...

Problems solved by technology

[0006] (2) The structural quality of traditional houses is not easy to control

However, the construction of traditional residences is affected by the level of on-site construction personnel and the construction environment. The construction quality is not easy to control, and there are many reasons for common quality problems.

[0008] (3) The production cost of traditional housing is high

[0009]Because of the "uniqueness" of traditional housing construction, it cannot be mass-produced, resulting in waste of materials, tools, etc.

In addition, the current labor cost continues to increase. As a labor-intensive traditional housing production, it also increases the production cost.

[0010] (4) High energy consumption in traditional residential construction

[0012] (5) There are many potential safety hazards in the construction of traditional houses

However, these two structural forms have their own shortcomings. The main disadvantage of the former is that a certain amount of on-site concrete is required, and the process equipment for wall panel prefabrication is high. In earthquake-resistant areas above 7 degrees and high-rise buildings, it is necessary to solve the problem of reinforced steel bars. connection problem

The main disadvantage of the latter is that it has higher requirements for the grouting and anchoring of the main reinforcement.

There are convex beams and columns in the interior, and the structure of the outer wall enclosure is relatively complicated

[0016] (2) The advantage of the existing industrialized housing is that it completes the structural combination of components with fewer specifications, and has a high degree of standardization, but it ignores the architectural design and does not meet people's expectations. architectural aesthetic requirements

[0017] (3) There are cost control problems in prefabricated high-rise residential buildings

Wet connection is a connection method that uses reserved steel bars and post-casting strips. After the components are installed, the reserved steel bars are connected and then concrete mortar is poured. This connection surface achieves the characteristics of cast-in-place structures, but on-site There are many operation nodes, and the pouring amount of each node is small, which is inconvenient for pouring
