Construction method of formwork support on one side of circular arc shear wall

Abstract

The invention discloses a construction method with supports and templates in the single side of an arc shear wall, and belongs to the technical field of architectural engineering. The method comprisesthe steps of measurement and line layering, steel bar installation, manufacturing the templates of the arc shear wall, assembling and fixing the templates, fixing the bottoms of the templates in theouter sides, erecting supports, concrete pouring and dismounting the templates and supports. The large templates are used to reduce splicing seams of the templates, reduce template assembling time andaccelerate construction; the customized arc templates of a steel and plastic combined template system are used to reduce the deviation of arc degree and verticality, and the engineering quality is improved; the bottom is fixed by split bolts and compressed by square strips in the lower, the template stability is improved, template displacement is reduced, and conditions including slurry leakage,surface unevenness, template expansion and staggering of the bottom of the exterior wall are avoided; a triangular steel pipe truss system of the wall uses steel pipes, fasteners and template steel bar back ribs for fixation, inclination of the templates is controlled and the safety is improved; and the large steel-plastic templates and the triangular steel pipe truss system are used repeatedly sothat energy is saved, the environment is protected and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a single-side formwork construction method for an arc shear wall. Background technique [0002] With the progress of the times, many buildings have begun to design shapes in order to highlight their advantages. For example, arc shear walls are more often applied to modern buildings, bringing people a new visual enjoyment. However, the application of arc shear walls has also brought many difficulties and inconveniences to the project construction. The main performance is that the design and installation of formwork and its supports are more complicated; the concrete pouring construction is difficult and so on. 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, which has high construction cost and low secondary utilization rate of steel formwo...
