Assembling and pouring integrated shear wall structure building system

Abstract

The invention relates to the field of fabricated buildings, and discloses an assembling and pouring integrated shear wall structure building system. The assembling and pouring integrated shear wall structure building system comprises a floor slab, a shear wall skeleton structure and wall templates arranged on two sides of the shear wall skeleton structure; the shear wall skeleton structure comprises a plurality of unit plane skeletons and unit three-dimensional skeletons; each unit plane skeletons comprises an upper horizontal member, a lower horizontal member and at least two vertical membersfixedly connected to the horizontal members in a perpendicular mode; and each unit three-dimensional skeleton is formed by enclosing the four unit plane skeletons. The standardized construction and three-dimensional installation are adopted, and the unit three-dimensional skeletons formed by the unit plane skeletons are constructed in an arrangement and combination mode. The installation efficiency is high. The steel skeleton combination forms an own stable structure without supporting supports and scaffoldings, manpower and material resources are greatly saved, a construction plane and construction space are provided for high-altitude operation in other processes, the processes cross one another and do not affect one another, the construction is safe and reliable, the installation efficiency is high, and the construction speed is high.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to an assembly and pouring integrated shear wall structure building system. Background technique [0002] The shear wall structure is a structural system in which the reinforced steel bars of walls, beams, and floors are poured together with concrete to form a whole, which can bear horizontal loads and vertical loads. The basic elements constituting the mechanical function of the shear wall structure system include: wall piers (shear wall body), hidden columns, buttressed wall columns, hidden beams, connecting beams, corner walls, winged walls, constrained edge components, and structural edges Components, embedded ends and bottom reinforcement areas (bottom cast-in-place layer, height not less than 1 / 10 of the total height). This structure can give full play to the good workability of concrete, high compressive strength, convenient construction, high overall rigidity, and goo...

AI Technical Summary

Problems solved by technology

[0006] (1) Splitting the shear wall in the structural design cannot give full play to the good properties of concrete materials such as good workability, good integrity, and high strength, which increases the difficulty of structural design and reduces the reliability of the load-bearing structure;

[0007] (2) Prefabricated shear walls are large in size and heavy in weight, complex in construction and installation, and low in efficiency. At the same time, a large number of connection nodes and joints are generated during assembly and installation, which weakens the integrity and overall stiffness of the shear wall and reduces the shear force. The mechanical performance and seismic performance of the force wall;

[0008] (3) Metal sleeve connection is used, which is expensive, time-consuming and labor-intensive, and increases construction costs

The grouting in the metal sleeve is a closed and concealed construction. It is difficult to completely discharge the air inside the sleeve, and it is easy to produce cavities that are not dense, and the density and quality monitoring of the grouting cannot be detected, which brings uncertainty to the reliability of the connection of the stressed steel bars. security risks

[0009] (4) The prefabricated shear wall has irregular dimensions and is not easy to transport

Factory prefabrication consumes a lot of energy required for molds and steam curing, which not only increases the price of concrete itself exponentially, but also increases the secondary transportation and costs from the factory to the construction site;

[0010] To sum up, the existing technical system of prefabricated shear walls is not perfect, and has not fundamentally and comprehensively solved the technical problems in the design, construction, installation, production and processing links, but simply split the design and superimposed assembly, As a result, the pain points of "increasing construction costs, low installation efficiency, long construction period, and difficulty in guaranteeing project quality" have arisen
