Precast steel bar truss shear wall

Abstract

The invention relates to a precast steel bar truss shear wall and belongs to the field of building components. The precast steel bar truss shear wall is characterized in that a shear wall adopts a precast steel bar truss concrete structure; a steel edge frame is arranged around the shear wall and is welded together with a steel bar truss; an embedded steel plate is arranged at the wall face of the shear wall; the steel edge frame and the embedded steel plate are welded with an anchor rod performing anchoring function; a concave pit is arranged at the upper end of the shear wall; and a short steel connector is welded at the steel edge frame at the lower end. The precast steel bar shear wall is simple in structure, the steel component and the steel concrete combined component have good connection performance, and precast production and site assembly and connection of the structure component can be better realized, so a building has excellent shockproof property, the structure component is accurate in size, the quality control is good, the building quality is improved, the service life is long, the labor environment of operation staff is improved to the greatest extent, the construction period is shortened, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the field of building components, in particular to a prefabricated steel bar truss shear wall. Background technique [0002] As we all know, in recent years, the construction of green, energy-saving and healthy buildings has become our basic national policy. The industrialized engineering construction model marked by standardization and industrialization requires factory-based prefabrication of engineering construction and on-site mechanized assembly. The formwork system required for prefabrication is relatively complicated, the cost is high, the operation of the connection between components is inconvenient, and the integrity is poor, which affects the development of prefabricated buildings. Therefore, it is urgent to find a technical measure to solve these problems; in order to achieve the above goals, the current All parts of the country are actively researching building structure technologies that meet this goal, including...

[0002] As we all know, in recent years, the construction of green, energy-saving and healthy buildings has become our basic national policy. The industrialized engineering construction model marked by standardization and industrialization requires factory-based prefabrication of engineering construction and on-site mechanized assembly. The formwork system required for prefabrication is relatively complicated, the cost is high, the operation of the connection between components is inconvenient, and the integrity is poor, which affects the development of prefabricated buildings. Therefore, it is urgent to find a technical measure to solve these problems; in order to achieve the above goals, the current All parts of the country are actively researching building structure technologies that meet this goal, including steel structure component prefabrication technology, reinforced concrete component prefabrication technology, concrete and steel composite component technology, and on-site assembly and connection technology for these building structural components. A hybrid structure building composed of components; but because the design and manufacturing technology of some structural components, as well as the overall assembly and connection structure of on-site mechanization are unreasonable, the research and development is not enough, and there are many problems that need to be improved urgently; in addition, through recent years In the analysis of earthquake disasters, the seismic design has made great progress, from a single seismic design to a combination of shock absorption and seismic design, and then improved to the seismic design to improve the energy dissipation capacity of structures and components. It is recognized that the improvement of prefabricated building structures Integrity and deformation energy consumption are important measures for earthquake resistance, especially steel structure buildings have the best seismic performance, so it is necessary to vigorously develop prefabricated and steel structure buildings
