Basic steps for reinforcement of aramid cloth

The construction project is very stress-relief. The degree of reinforcement is very important for a building. The common reinforcement method is to add welded steel and steel plates. This method will increase the size of the structure to a certain extent and increase the structural weight. The change in stiffness results in the redistribution of the internal forces of the structure and the construction is subject to certain difficulties and dangers due to the use of mechanical equipment, especially at high altitudes.

Therefore, it is preferred to use some lightweight reinforcing materials such as carbon fiber and aramid cloth in the building. What is the basic procedure for the reinforcement of the aramid cloth? It can be carried out according to the following requirements.

1. Construction preparation

2. Surface treatment of concrete members: the weathered layer and the plaster layer with insufficient strength are removed, and the surface is repaired and leveled.

3. After the concrete surface has been leveled, clean it before applying the primer.

4. Prepare and brush the bottom layer, the specific steps are as follows:

(1) Cut the aramid cloth according to the requirements of the construction drawings.

(2) Ink line

(3) Preparation of impregnating resin

(4) Coating underlayer impregnating resin

(5) Pasting aramid fiber cloth: The aramid cloth is pasted according to the construction drawing, and the aramid fiber cloth is repeatedly rolled by the roller to make it closely combine with the concrete.

(6) Coating outer layer impregnating resin: After the bottom layer resin is impregnated with the fiber cloth, the outer layer is further coated with the resin. The resin is evenly applied by the roller along the direction of the aramid fiber, and is repeatedly rolled to remove residual bubbles, so that the aramid cloth, the resin and the concrete member are bonded together.

(7) Multi-layer bonding: When two or more layers of aramid cloth are pasted, the above construction process of d-f is repeated.

(8) Maintenance

5. After the aramid cloth is pasted, it should be properly externally protected.

Because of its own characteristics, aramid fiber cloth is suitable for building reinforcement, and its reinforcement step is relatively simple. Usually, the aramid cloth is cut according to the construction drawing, and then the ink line is cut. The specific steps are As mentioned above, this side will not be repeated. If there is any missing, welcome to add it. Here is a small series. If you need this product, you can contact us to know that it will not melt under high temperature conditions. , meltdown, when the temperature is greater than 370 °C, it begins to carbonize, which is a good product.
