Connection structure of building composite floor slab and steel bar truss shear wall

Abstract

The invention relates to a connection structure of a building composite floor slab and a steel bar truss shear wall, and belongs to the field of building members. a one-way or two-way prestressed steel bar and a light steel rid are embedded in a prefabricated slab at the lower part of the connection structure; an oblong hole is formed in the end part of the light steel rib; an upper layer steel bar of the composite floor slab is paved in a notch in the upper part of the light steel rib; poured-in-place concrete is positioned at the upper part of the prefabricated slab to cover the light steel rib and the upper steel bar; a steel frame is arranged at the periphery of the shear wall, and is welded with a steel bar truss together; a pre-buried steel plate is arranged on the wall surface of the shear wall; a steel plate bracket, a reinforcing steel bar and a connecting plate all connected with the composite are welded onto the pre-buried steel plate; a concave pit is formed in the upper end of the shear wall; a short pattern steel fastener is welded on the steel frame at the lower end of the shear wall; the shear wall is connected with the composite floor slab; the composite floor slab is directly placed on the steel plate bracket of the shear wall, and is fixed in a manner that a bolt penetrates through the oblong hole in the end part of the light steel rib and the oblong hole in the connecting plate welded on the pre-buried steel plate of the wall surface of the shear wall; meanwhile, the reinforcing steel bar welded on the pre-buried steel plate of the wall surface of the shear wall is connected with the composite floor slab.

Description

Technical field [0001] The invention relates to the field of building components, in particular to a connecting structure of a building's laminated floor slab and a reinforced 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 prefabrication of engineering construction as the mainstay, and on-site mechanized assembly cooperation. The formwork system required for prefabrication is relatively complicated, high cost, inconvenient operation of the connection between components, and poor integrity, which affects the development of prefabricated buildings.

[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
