In the past, there was a link in the process of building formwork construction that tested the skills and experience of carpenters, that is, square column reinforcement. Not to mention the use of many materials, complex technology, low efficiency, and the result is easy to fall apart and explode, so many carpenters are reluctant to do this job. However, with the continuous innovation of building materials, a new type of square column reinforcement has emerged, which makes the square column reinforcement simpler and faster.

It is the latest star product developed by Dongshida: square column reinforcement.

The "appearance" of the square column reinforcement in Dongshi University is very common, as shown in the following figure:

But compared with the traditional reinforcement method, its advantages are outstanding:

1. Light weight, simple structure and convenient operation.

The materials required for the reinforcement of Dongshida square column are composed of four main parts and four inclined irons, and the construction is simple and fast. Compared with the traditional reinforcement method, the weight is reduced by 25% and the installation speed is increased by 4-6 times without affecting the strength.

2. Save materials and ensure quality.

Compared with the traditional formwork reinforcement method, Dongshida square column reinforcement has sufficient strength and stiffness, and the appearance quality of concrete after demoulding is good. Because the template does not need to be punched, the turnover times of the wooden template are increased and good economic benefits are created.

3. Scope of application

The application technology of special-shaped square column reinforcement can speed up the construction progress, save the construction site and ensure the construction quality, which is suitable for the reinforcement of rectangular column formwork with side length of 400- 1600.

The invention is suitable for the reinforcement of the common cast-in-place reinforced concrete square column template in engineering construction, especially for the case that the side length of the square column is about1m.
