Overlapped shear wall with prefabricated part and cast-in-situ part and manufacturing method thereof

Abstract

The invention belongs to the technical field of the civil engineering building structure, in particular to an overlapped shear wall with a prefabricated part and a cast-in-situ part and a manufacturing method thereof. The traditional reinforced concrete shear wall is divided into two parts, wherein one part is prefabricated (a PCF plate) in a factory; the other part is cast in situ in a construction site; and after block cast, the prefabricated part (the PCF plate) and the cast-in-situ part are formed the overlapped shear wall. The plate thickness of the prefabricated PCF plate is commonly controlled at 60-80mm. The plate width of the single PCF plate is not greater than 3.0m, the plate height is not greater than 6.0m, and the plate weight is not greater than 2 tons. A single-layer two-wayreinforced bar net piece is configured in the plate; simultaneously, longitudinal and transverse overlapped reinforced bars are embedded at the inner side according to a distance of 450-600mm in advance, and the exposed parts of the overlapped reinforced bars are anchored into the cast-in-situ part. Compared with a pure external-hanging wall plate of a shear wall structure used at present, the invention lessens the self weight, lowers the construction difficulty, enhances the production efficiency and the construction quality and has energy saving and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of building structures of civil engineering, and in particular relates to a novel energy-saving laminated shear wall partly prefabricated and partly cast-in-place and a manufacturing method thereof. Background technique [0002] The construction of reinforced concrete houses in my country is still dominated by the traditional on-site wet construction mode. This production method has serious waste of resources and energy, serious environmental pollution, high labor intensity, low productivity, chaotic management, and uneven product quality. , It is easy to produce inferior products and other characteristics. In order to change this status quo and cooperate with the construction of a resource-saving and environment-friendly society, the state has issued a series of relevant policies to encourage and promote the development of housing construction in the direction of industrialization. The key to the modernizat...

Problems solved by technology

But practice has proved that this kind of pure external wall panel has the following disadvantages: 1) The prefabricated external wall panel is generally 70-90mm thick and equipped with a single-layer two-way steel mesh. The use of formwork wastes materials and increases the weight of the structure, which is unfavorable for earthquake resistance; 2) The inner side of the prefabricated wall panel is pre-embedded with horizontal and vertical reinforcement ribs, which makes it difficult to locate and bind the cast-in-place reinforcement, which indirectly increases the construction cost; 3 ) has higher requirements on the comprehensive quality of construction personnel and construction management level

It is estimated that the construction cost per building square meter of the shear wall structure house with external prefabricated wall panels will increase by about 700 yuan
