Abstract

The invention discloses a prefabricated reinforced concrete volute template and a construction method thereof. A volute inner die comprises an inner die support and an inner die template, and the inner die support connects radial steel trusses of each roof truss at radial intervals from the volute inner wall to the volute outer wall into a whole by using annular connecting steel bars; the radial steel truss has a shape with wide lower edge and narrow upper edge, the outer end of the radial steel truss is vertical, the upper part of the inner end of the radial steel truss accords with the volute inner wall in shape, the middle part of the inner end of the radial steel truss is horizontal, and the lower part of the inner end of the radial steel truss is vertical; and the inner die template takes joist steels connected at the inner end of the radial steel truss as main keels and takes battens blocked between the joist steels as secondary keels, lining plates are fixedly connected on the battens, and inner die panels are nailed on the surfaces of the lining plates. The template solves the problem of complex and difficult construction of the prefabricated reinforced concrete volute with complex shape, and does not need high-precision processing equipment; and the steel-wood combined template can be reused, has low cost, simple and reliable construction process and convenient operation, and greatly saves the construction cost.

Description

technical field [0001] The invention relates to a formwork for pouring reinforced concrete components and a construction method thereof. Background technique [0002] The volute is a reinforced concrete component used in the construction of a power plant. The volute is located above the neck of the water inlet and is the connecting section connecting the water inlet and the circulating water culvert. Because it is shaped like a snail, it is commonly called the volute. The outside of the volute is Polygonal, the interior diverges outward from the center of the volute, and an inverted hollow circular platform in the middle. Each volute is composed of 4 assembled parts, the shape is complex, and the construction is difficult. Contents of the invention [0003] The purpose of the present invention is to provide a prefabricated reinforced concrete volute formwork and its construction method, to solve the technical problem that the volute construction method is complicated and d...
