Concrete shear wall structure and its construction method based on 3D printing

Abstract

The invention discloses a concrete shear wall structure based on 3D printing and a construction method of the concrete shear wall structure. The construction method comprises the following steps that (a) a first layer of prefabricated concrete shell is manufactured by adopting 3D printing; (b) a first layer of tie bars and / or horizontal bars are arranged on the top of the first layer of prefabricated concrete shell; (c) a second layer of prefabricated concrete shell is manufactured on the top of the first layer of prefabricated concrete shell, and the two ends of the tie bars and / or the horizontal bars are embedded into the prefabricated concrete shells respectively; (d) a second layer of tie bars and / or horizontal bars are arranged on the top of the second layer of prefabricated concrete shell, the step (c) is repeated until the prefabricated concrete shells are completed to reach designed elevation, and concrete is poured. The tie bars are prefabricated between an inner wall faces and an outer wall faces of the prefabricated concrete shells to prevent formwork expansion, the horizontal bars of a shear wall are also embedded between the prefabricated concrete shells, construction inconvenience brought by the horizontal bars in the later mounting process is avoided, and construction is simplified.

Description

technical field [0001] The invention relates to a shear wall, in particular to a concrete shear wall structure based on 3D printing and a construction method thereof. Background technique [0002] The traditional shear wall construction adopts cast-in-place concrete construction. First, the shear wall reinforcement cage is bound, including the shear wall horizontal reinforcement and the shear wall vertical reinforcement. After the reinforcement cage is bound, the shear wall formwork is installed on both sides of the reinforcement cage. And the formwork on both sides is connected by the way of piercing tie bars to prevent the expansion of the mold during the later concrete pouring process. Finally, the shear wall concrete is poured in the formwork, and the formwork is removed after the concrete is finally set. construction. [0003] The traditional cast-in-place concrete shear wall construction process is complicated, and cannot be adapted to the prefabricated reinforced con...

Problems solved by technology

[0005] However, this prefabricated reinforced concrete structure cannot be applied to the construction of shear walls due to the inability to install tie bars. Therefore, it is necessary to propose a method of how to install tie bars in the prefabricated concrete shell to prevent concreting. Die expansion problem
