Annular strip bracket concrete template device and bracket concrete templates

Abstract

The invention provides an annular strip bracket concrete template device and bracket concrete templates. The annular strip bracket concrete template device comprises steel pipe bents. The steel pipe bents support the bracket concrete templates through I-shaped steel. In the bracket concrete templates, each template is in a shape of a toppled L and comprises a vertical arc-shaped panel and an inclined sector-shaped panel, the upper end of each vertical arc-shaped panel is connected with the lower end of each inclined sector-shaped panel, and a rib plate and a supporting frame are arranged on the back of each template. A vertical bulk template is arranged above each bracket concrete template and fixedly connected with poured concrete through a template brace. A ring is defined by a plurality of bracket concrete templates and a plurality of bulk templates, and the bracket concrete templates and the bulk templates are connected through purlins. The templates in the shape of the toppled L are matched with the bulk templates, a drawing down portion of annular strip bracket concrete can be molded very conveniently, the templates are made accurately, joints between the templates are tight, the concrete molded through pouring is graceful in figure and high in appearance quality, and the templates can be reused.

Description

technical field [0001] The invention relates to the field of formwork for concrete construction, in particular to a formwork device for pouring annular strip corbel concrete on the top of a windshield wall of a hydroelectric generator and a formwork assembly therein. Background technique [0002] The top of the windshield wall of the hydroelectric generator of a hydropower station is usually designed with an annular strip-shaped corbel concrete structure. When performing formwork construction, the traditional construction method adopts a wooden formwork method, because the annular strip corbel concrete has a reduced diameter arc. The structure and wooden formwork are difficult to manufacture, and there are problems such as poor joints of the formwork, easy deformation of the panels, easy breakage of the formwork after removal, and inability to be reused. At the same time, the concrete after pouring has poor shape and many appearance defects. Contents of the invention [00...

Problems solved by technology

[0002] The top of the windshield wall of the hydroelectric generator of a hydropower station is usually designed with a ring-shaped corbel concrete structure. When performing formwork construction, the traditional construction method adopts a wooden formwork method, because the ring-shaped corbel concrete has a shrinking arc structure, wooden formwork is difficult to manufacture, and there are problems such as poor joints of the formwork, easy deformation of the panels, easy breakage of the formwork after removal, and inability to be used for turnover. At the same time, the concrete after pouring has poor shape and many appearance defects
