Master the details and waterproof of steel formwork before use

When using the steel template, if you want it to work well, you must pay attention to some small details before using it, only After grasping some small details, you can use it effectively. Let’s take a look at the steel template before use with us Hubei Wangke Formwork Co., Ltd. Things to pay attention to!

1, no oil

It is required to remove automobile engine oil, edible oil or any oil stains on the surface of the steel template. Commercial degreasing agents can also be used as detergents with stronger detergency. The items to be cleaned are hard floor brushes, which are divided into small floor brushes and horizontal floor brushes.

2, no rust

It is required to remove rust, welding slag and other paints on the surface of the steel template, when the flat template is treated with rust prevention Combined with the practical activities of the construction site, it is usually sufficient to use a polishing machine with a wire brush to remove rust. It is sufficient to remove the floating rust. The standard only requires one treatment. If the rust is severe, the treatment frequency can be increased appropriately, but be careful not to over-smooth the surface treatment. That would jeopardize the turnover frequency of the template paint.

3, dry

We all know that the material of the steel template is pipe fittings. If the pipe fittings are invaded by water, they will rust, so Template drying is an important standard that we all understand

4, clean

The steel template is required to be cleaned before the template paint is applied. Some floating dust on the surface can be wiped clean with a dry sponge Just use pure cotton cloth or turpentine water to clean the surface of the steel formwork for engineering construction and dry it with a dry cloth. When painting, construction workers need to bring foot covers to prevent the dirty steel formwork from affecting the actual effect.

Because of the performance advantages of steel formwork in current construction projects, it has been widely used, but steel formwork is in use Sometimes due to quality reasons or construction reasons, the steel formwork will leak water. What will happen if this happens? How should we prevent this from happening?

steel template with cracks will see water when it is deployed on the construction site, which will reduce the use cycle. Therefore, in order to reduce this situation, preventive measures must be taken, so how can we prevent it? In fact, it is also simple. The water leakage is only due to cracks in the steel formwork. We only need to solve the cracks in the steel formwork. Let's take a look at how to prevent the steel formwork from cracking!

1. When installing the bridge steel formwork, ensure that the structure is inseparable, does not leak grout, does not leak, and the shape is standard. Ensure the uniformity of the concrete.

2. Before tying the steel bars, thoroughly remove the rust to ensure the quality of the used steel bars. Put the rebar in the interval.

3. Resolve bridge steel formwork and support capacity, stiffness and reliability for correction, not blindly follow the trend and follow the work Experience and similar projects are used mechanically.

4. The structural mutation or cross-sectional mutation of the steel formwork of the bridge should be minimized. If structural mutation is unavoidable, it should be implemented. The details are dealt with, and the structural reinforcement is improved to improve the crack resistance of the concrete.
