Supporting device of three-dimensional arc cantilever concrete component formwork

Abstract

The invention discloses a supporting device of a three-dimensional arc cantilever concrete component formwork. The supporting device comprises a main framework steel keel. The section curvature of the main framework steel keel is the same as that of an arc cantilever component. Transverse flat steel which is 6 millimeter thick and 60 millimeter long and the same as the main framework steel keel in section curvature is welded to the inner side of the main framework steel keel in the direction vertical to vertical flat steel; the root of the main steel keel is connected with a base in a welded mode, so that positioning of the keel is facilitated. The structural style and stress features of the arc cantilever component are taken into comprehensive consideration, the keels are manufactured and arranged purposefully, overall stability of the framework in the concrete pouring process is guaranteed, the formwork is easy and efficient in installation, the main steel keel is manufactured in a factory, lofting cutting is carried out by means of advanced numerical control equipment, arc formwork modeling is guaranteed, the keels can be recycled after being detached, and the environment protection concept of waste recycling is practiced.

Description

technical field [0001] The invention relates to a three-dimensional arc-shaped cantilever concrete member formwork supporting device, which belongs to the technical field of building construction. Background technique [0002] In construction engineering, the spatial arc-shaped cantilevered concrete structure has a long span and variable shape, and the section changes every 500mm along the span direction of the frame, so it is difficult to guarantee the forming effect. The supporting device currently used is complex in structure and inconvenient to use, and Can not be reused after use, resulting in waste. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a three-dimensional curved cantilevered concrete member formwork supporting device with reasonable structure and convenient construction. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present inv...
