Abstract

The invention relates to a semi-fabricated reactive powder concrete-plain concrete (RPC-PC) bundle shear wall composite structure. The semi-fabricated RPC-PC bundle shear wall comprises a lower end beam, shear columns and an upper end beam. Two ends of the shear columns are fixedly connected with the lower end beam and the upper end beam respectively; and each shear column comprises a reactive powder concrete outer formwork and plain concrete filled in an inner space of the reactive powder concrete outer formwork. The RPC-PC bundle shear wall uses material advantages of RPC to improve a stress performance and an anti-seismic performance and also to improve a fire resistance, an impact resistance, a corrosion resistance and the like. Besides, the RPC is prefabricated into the outer formwork of the shear wall to form the outer formwork of the RPC-PC bundle shear wall. The combination form can save a large number of wood formworks and steel formworks. The semi-fabricated RPC-PC bundle shear wall has a small influence on the surrounding environment, improves working efficiency, particularly reduces a later maintenance cost, and has a wide engineering use prospect.

Description

technical field [0001] The invention relates to the technical field of concrete shear walls, in particular to a semi-fabricated RPC-PC bundle shear wall composite structure and a preparation method thereof. Background technique [0002] The rapid development of prefabricated buildings has had a huge impact on the construction industry. The use of prefabricated technology can efficiently utilize resources and energy, and has the advantages of rapid construction, improved construction efficiency, controllable quality and environmental protection. However, most of the current domestic concrete shear walls are mainly traditional cast-in-place, which requires a large number of wooden formwork and steel formwork during construction. Contradictory ideas. Contents of the invention [0003] In order to solve the above-mentioned background technical problems, the present invention proposes a semi-fabricated active powder concrete (Reactive powder concrete, hereinafter referred to a...
