Building adopting aseismatic precasted reinforcing steel truss shear wall composite structure

Abstract

The invention relates to a building adopting an aseismatic precasted reinforcing steel truss shear wall composite structure, and belongs to the architectural field. The building adopts the scheme that reinforcing steel truss concrete shear walls provided with steel frames and composite floor slabs with prestressed concrete sheets are precasted; a foundation is connected with steel columns and the shear walls; the steel columns are connected with steel beams; the steel beams are connected with the composite floor slabs and the shear walls; the shear walls are connected with the composite floor slabs; an upper section of each shear wall is connected with the lower section of each shear wall; the steel columns are connected with the shear walls; the steel beams are combined and connected with the shear walls. According to the invention, the safety, economy and durability of the building can be ensured in virtue of the reliable integrity and seismic resistance of the connection between the structural elements; the steel structural elements and the steel concrete composite members have favorable connection performance, the labor environment for operators is improved, the construction period is shorted and the construction cost is reduced furthest; besides, the large span can be realized as the building structural elements are made of steel materials with higher strength, so that the building is easy to refit and renovate after several years, and the high durability is realized.

[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 with the best seismic performance, so it is necessary to vigorously develop prefabricated and steel structure buildings; at the same time, the stairs, structural components and masonry infill walls in the building structure The connecting structure often has problems due to improper handling of the structural structure, which aggravates the earthquake disaster
