How to Use Building Formwork?

Construction formwork includes four aspects when used: pre-construction preparation, reinforcement binding, formwork installation, and concrete pouring. As an anti-plastering formwork in construction formworks, the aluminum alloy formwork is also very convenient to use, which is prefabricated by the manufacturer in advance. When construction is used, it can be completed by assembling it like playing with building blocks according to the number, and then proceeding with reinforcement binding and concrete pouring, thus completing the use of the construction formwork.

Pre-construction preparation of construction formwork

Measurement and layout

Before using the construction formwork, put the wall and column boundary line, control line, and opening line, and measure the elevation of the center line position line;


Apply cement slurry to the leveling layer along the outer edge of the construction formwork components to ensure the correct position of the construction formwork and prevent leakage of the bottom of the construction formwork;


Chisel the concrete at the vertical joint when assembling the aluminum alloy construction formwork;

Prepare release agent

Prepare release agent for brushing, and do not use waste oil or other oils.

Reinforcement binding of construction formwork

Use the positioning ribs of the welded construction formwork with the wall and column boundary line and the control line, and the diameter of the steel bars in the earth wall and column is small, which is prone to offset. The steel bar heads can be pre-embedded for welding the positioning ribs.

Installation of construction formwork

The aluminum alloy construction formwork is prefabricated and assembled, the reinforcement is bound, the wire tube and junction box are pre-embedded, the construction formwork is installed and fixed with the positioning bolts through the wall, the yin and yang corners of the formwork are installed, the beam and plate formworks are assembled and connected, and the verticality of the construction formwork is adjusted, and diagonal braces or stable brackets are erected for inspection and correction.

Pouring concrete for construction formwork

When pouring concrete, if the particle size of the aggregate is improper or the coarse aggregate is too much, the cement slurry will not be compact, resulting in free voids. In addition, it is not allowed to pour too high at one time, and vibrating after the cement slurry fills the construction formwork will cause air discharge obstruction, resulting in bubble phenomena after demolding.

Precautions for the use of construction formwork

There are some precautions during the use of the construction formwork, such as the need for neat and flat placement during storage, attention to temperature and dryness, and storage at room temperature. During transportation, it is necessary to ensure that the construction formwork is tightly strapped and not exposed to direct sunlight.

During transportation

During the transportation of the construction formwork, attention should be paid to its protection, preventing it from being exposed to the sun and rain, and preventing it from being deformed under environmental effects, affecting its use during construction.

During construction

The construction formwork should be arranged neatly and placed on a flat ground during construction to avoid stacking and compression, and also avoid placing it in a place with a high temperature and very dry environment, keeping the location at a constant temperature and dryness to prevent dampness. At the same time, avoid direct sunlight on the formwork.

During transportation

During the transportation of the aluminum alloy construction formwork, attention should be paid to firm bundling to prevent damage caused by falling and possible accidents.

The above is the introduction of the use of construction formworks. The aluminum alloy construction formwork has strong corrosion resistance and mechanical properties, and no construction waste is left during use. It has a high turnover rate and can be used repeatedly, saving a lot of labor, transportation, cement, sand, and other costs.
