Connection structure of building composite floor slab and steel tube shear wall

Abstract

The invention relates to a connection structure of a building composite floor slab and a steel tube shear wall, and belongs to the field of building members. A shear wall is connected with a composite floor slab; the composite floor slab is directly placed on a steel plate bracket of the shear wall, and is fixed in a manner that a bolt penetrates an oblong hole of the end part of a light steel rib and the oblong hole in the connecting plate welded on the side surface of the shear wall; meanwhile, a reinforcing steel bar welded onto the side surface of the shear wall is connected with the composite floor slab; the concrete is poured in place at the upper part of a prefabricated slab to cover the light steel rib, an upper layer steel bar and the reinforcing steel bar. The connection structure is simple in structure, and the steel structural member and the steel concrete combined member have excellent connection performance to realize the prefabrication production and field assembly and connection of the structural members better, so that the building has excellent seismic restraint performance.

Description

technical field [0001] The invention relates to the field of building components, in particular to a connection structure between building laminated floors and steel pipe shear walls. 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.

[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
