Description

A prefabricated steel tube bundled concrete wall frame structure system

technical field

The utility model relates to the technical field of construction engineering, in particular to an assembled steel pipe beam concrete wall frame structure system.

Background technique

The "Thirteenth Five-Year "Prefabricated Building Action Plan" clearly pointed out that by 2020, the proportion of national prefabricated buildings accounting for more than 15% of new buildings, of which the key promotion areas will reach more than 20%, encourages all regions to set higher development goals.

The composite structure of steel tube bundles better utilizes the advantages of light weight and high strength of steel and high rigidity of concrete, and avoids the disadvantages of poor stability of steel components, brittleness of concrete and rapid stiffness degradation. The composite structure of steel pipe bundles can be produced by industrial production lines, and the whole process can be operated by robots. It is an ideal form of prefabricated building structure. The steel tube bundle composite structure can effectively reduce the structural weight and improve the seismic performance of the structure. The combined structure of steel pipe bundles has a high degree of industrialization, and the installation and construction speed is fast. Compared with the reinforced concrete structure, the steel tube beam concrete composite structure consumes less area and has a higher room yield. However, the existing steel tube beam concrete composite structure is mainly used in the shear wall structure system, and this structure still has many limitations. Such as: 1. It is inconvenient to open holes on the wall. The design and processing of the opening joints in the combined steel pipe bundle shear wall are complicated, and the opening will inevitably weaken the performance of the wall. 2. The layout of doors and windows is limited. The layout of door and window openings needs to avoid shear walls with long wall plinths, and the freedom of door and window layout positions is limited. 3. The layout of steel pipe bundle combined shear wall limbs will cause waste, and sometimes in order to improve the overall rigidity of the structure, it also increases the structure's own weight and construction cost. Therefore, the advantage of using simple steel tube beam composite shear wall structure is not obvious, which is not conducive to the popularization and application of steel tube beam concrete composite structure in multi-storey buildings and low seismic intensity areas.
