Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a template reinforcement system for independent column construction. Background Art

[0002] Single-story production plants, warehouses and other single buildings are usually designed as reinforced concrete frame structures with light steel roof structures. The vertical components in the frame structure are independent reinforced concrete columns, which are continuously set from the bottom to the top of the floor and connected to the frame beam at the top. The stability and anti-overturning of the formwork reinforcement system during the construction of independent columns are difficult points.

[0003] There are two conventional construction methods for independent columns. One is to set up lantern racks around the column, or set up full-height scaffolding. The column formwork reinforcement is tied to the scaffolding to ensure the out-of-plane stability of the column formwork. The other method is to use the construction method of municipal bridge piers, that is, the climbing formwork construction process, to achieve the out-of-plane stability of the upper column formwork by fixing it to the cast section at the bottom, and then climbing up continuously after casting. The above two construction methods not only occupy a large amount of turnover materials, have a long construction period, but also have high construction costs, which is extremely uneconomical.
