How to deal with frame columns reinforced with angle steel

The reinforcement technology of angle steel wrapped concrete frame columns refers to the reinforcement method of wrapping steel bars around beams and columns. Generally, steel is wrapped with angle steel, and steel can also be wrapped with channel steel or steel plate, which can be divided into dry method and wet method. Bonding steel reinforcement method The so-called column bonding steel reinforcement method is to wrap bonded angle steel and bonded steel plate to improve the bearing capacity of the column at the newly added cross section, and make the original concrete column better due to the lateral restraint of the newly added steel plate hoop.

Frame columns are reinforced with angle steel.

With the rapid development of society, the construction industry in China has quietly changed. Nowadays, many building structures are frame structures, because they can provide flexible use space and seismic performance for buildings. However, even such a good building frame will have a series of problems such as concrete weathering, surface cracking and steel bar exposure. Once such problems occur, they need to be reinforced in time.

Firstly, the actual situation of frame columns is investigated, and then the construction conditions are comprehensively considered. Carbon fiber reinforcement method can be used around the column, that is, carbon fiber cloth is wrapped on the column with adhesive. The restraining effect of carbon fiber cloth on concrete is absolutely similar to that of stirrup wrapping, which can make the concrete wrapped by carbon fiber cloth in a three-dimensional compression state.
