A Construction Method of Cast-in-situ Reinforced Concrete Special-shaped Inclined Slab

Abstract

The invention discloses a construction method for cast-in-place reinforced concrete special-shaped inclined slabs, which comprises the following steps: CAD lofting → measurement and positioning → formwork and steel bar processing → beam formwork support → outer wall formwork installation → binding beam, slab, column wall reinforcement and pre-embedded Pipeline → installation of formwork on the inner side of the exterior wall → inspection and acceptance of formwork and steel bars → concrete pouring → concrete curing → formwork removal. The cast-in-place reinforced concrete oblique special-shaped structure and component construction method of the present invention overcome the shortcomings in the previous construction, the formwork is simple to make, the size is accurate, the reinforcement is convenient, the component slope is controlled accurately, and the concrete perception quality is good, which is the construction method of similar projects. Reference value is provided.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a construction method for cast-in-place reinforced concrete special-shaped inclined slabs. Background technique [0002] The facade of a library project is a conical building with a sloping roof, and the building area is 4320.8m 2 , 3 floors above the ground, frame-shear structure, with a total building height of 23.7m, is a multi-functional building for science, culture, education and scientific research institutions that collects, collates, preserves, disseminates and provides literature. The project quality requirements are high and the construction is difficult . The external walls above the second floor of the project adopt special-shaped curved surface structure. The external walls are composed of multiple external wall panels with different directions and slopes. The slope of the external wall panels is between 61° and 67°. bi-directional The sloping sl...

Problems solved by technology

The external walls above the second floor of the project adopt special-shaped curved surface structure. The external walls are composed of multiple external wall panels with different directions and slopes. The slope of the external wall panels is between 61° and 67°. bi-directional The height of the sloping slabs on the outer wall reaches 20 meters, and roots start from the arc roof on the first floor. Because it is not easy to set out the construction line on the arc, and the inclination direction and slope of the outer wall panels are complex and diverse, it brings great difficulties to the construction.
