Construction method for cast-in-place reinforced concrete special shaped sloping plate

Abstract

The invention discloses a construction method for cast-in-place reinforced concrete special shaped sloping plate, which includes the following steps: CAD setting out-measuring and positioning-templateand preparation of reinforcement-bracing of beam template-mounting of outer side template of outer wall-binding reinforcing steel bars of beam plate pillar wall and pipeline pre-burying-mounting of inner side template of outer wall-checking and inspecting of templates and reinforcing steel bars-pouring of concrete-maintenance of concrete-template removal. The cast-in-place reinforced concrete sloping special shaped structure and a member construction method solve deficiencies in former construction, and have the advantages that the template manufacture is simple, the size is accurate, the reinforcement is convenient and quick, the inclination of the member is accurately controlled, the appearance quality of concrete is good, and reference is provided for construction of similar projects.

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.
