Construction method of cast-in-situ oblique arc-suspended concrete shear wall

Abstract

The invention discloses a construction method of a cast-in-situ oblique arc-suspended concrete shear wall, which comprises the following steps of: (1) dividing the projection of the outer side lines of an inner arc template and an outer arc template of a basement of the oblique arc-suspended concrete shear wall and the projection of the outer side lines of an inner arc template and an outer arc template of a wall crown of the oblique arc-suspended concrete shear wall into equal parts; (2) determining the erection position of a total station and the coordinates thereof to obtain the distance between the total station and each equal part point of the projection of the outer side lines of the inner arc template and the outer arc template of the basement and the outer side lines of the inner arc template and the outer arc template of the wall crown; (3) erecting the total station and rotating the total station at an a1 angle by taking the starting point of the axis of the basement as a backsight point; (4) determining the positions of the projection of the outer side lines of the inner arc template and the outer arc template of the basement of the shear wall and the outer side lines of the inner arc template and the outer arc template of the wall crown of the shear wall; (5) installing the templates; (6) fixing the templates; and (7) after installing a die carrier and inspecting to be qualified, pouring concrete. The construction method is simple and easy and has high work efficiency, accurate measurement and positioning and low cost.

Description

technical field [0001] The invention relates to the technical field of concrete structure construction, and more particularly relates to a construction method for a cast-in-place inclined suspended arc concrete shear wall. Background technique [0002] With the progress of the times, architects often pay attention to the beauty of form while considering the beauty of the building's function. For example, inclined cantilevered concrete shear walls are often applied to modern buildings, bringing people a new visual enjoyment. However, the use of inclined cantilevered concrete shear walls has also brought many difficulties and inconveniences to the construction of the project, mainly due to the complicated design and installation of formwork and its supports, and the difficulty of concrete pouring and construction. The conventional construction method is to use stereotyped arc-shaped steel formwork and arc-shaped square steel or steel pipe corrugation as the formwork system, b...

Problems solved by technology

However, the use of inclined cantilever concrete shear walls also brings many difficulties and inconveniences to the construction, mainly due to the complicated design and installation of formwork and its supports; difficulties in concrete pouring construction, etc.

The conventional construction method is to use stereotyped arc-shaped steel formwork and arc-shaped square steel or steel pipe corrugation as the formwork system, but the construction cost is high, the secondary utilization rate of steel formwork and corrugation is low, and the shear wall is vibrated due to the inclination angle. When the rod is inserted, it is easy to be interfered by the steel bar, and it is difficult to insert it in place, which may easily cause problems such as insufficient vibration
