Template supporting structure for cast-in-situ limestone flour chamber

Abstract

The invention discloses a template supporting structure for a cast-in-situ limestone flour chamber. The template supporting structure comprises an inner template supported along the circumference direction on one side of a double-layer reinforcing steel bar rack, an outer template supported along the circumference direction on the other side of the double-layer reinforcing steel bar rack, a reinforcing steel bar inner support and a reinforcing steel tube. The inner template and the outer template are combined steel templates; a deformation adjusting groove is arranged on the back face of a panel; a deformation adjusting opening is formed between an edge rib and a vertical rib on the deformation adjusting groove; a plurality of reinforcing loops are uniformly distributed in the vertical direction on the outer side of the inner template; a plurality of reinforcing belts are uniformly distributed in the vertical direction on the outer side of the outer template; the reinforcing steel tube is arranged at the upper ends of the inner template and the outer template; buckles are fixedly mounted at the both ends of the reinforcing steel tube; and the buckles are respectively clamped on the outer sides of the inner template and the outer template. The invention provides the template supporting structure for the cast-in-situ limestone flour chamber. The inner template and the outer template of the limestone flour chamber are supported by using the template supporting structure, so that the supporting density of a scaffold can be greatly reduced; the labor and the material can be saved; and the phenomenon of template extension in a casting process can be prevented simultaneously. Therefore, the casted limestone flour chamber is formed in a good shape.

Description

technical field [0001] The invention relates to the technical field of construction of a limestone powder silo, in particular to a formwork support structure for a cast-in-place limestone powder silo. Background technique [0002] The limestone powder silo is an auxiliary equipment in the flue gas desulfurization process of the power plant, and is used for storing limestone powder. The limestone powder silo is a circular cylinder structure with a diameter of 12m and a wall thickness of 0.5m. Limestone powder silos are usually made of reinforced concrete. In the prior art, before the reinforced concrete is poured, it is necessary to bind the steel frame, and the inner formwork and the outer formwork are respectively supported on the inner and outer sides of the steel frame. The inner formwork The outer formwork and the outer formwork are thin steel plates, which are arranged along the circumference of the steel frame to form a circle; the outer sides of the inner formwork an...

AI Technical Summary

Problems solved by technology

The supporting structure of the formwork in the prior art has the following deficiencies: one, the inner formwork and the outer formwork used for supporting the formwork are all assembled by combined steel formwork, and the existing steel formwork is in order to enhance the strength of the combined steel formwork and facilitate the integration of the formwork with the formwork. For the connection between the formwork, there are ribs around and on the back of the panel of the combined steel formwork. The ribs make bending very difficult, so as to affect the forming shape of the limestone powder silo. After the formwork is removed, it needs to be chiseled and plastered

2. Due to the large size of the limestone powder silo, in order to better support and fix the inner formwork and outer formwork, it is necessary to support a large number of dense scaffolding on the outside of the inner formwork and outer formwork to support and fix each inner formwork and outer formwork. Not only is it difficult to support and consume a lot of manpower and materials, but it is also difficult to ensure the molding quality of the limestone powder silo
