In the process of building a pre-engineered steel factory, the processing and erection of reinforcement is an important stage to help the factory be solid and accurate as the drawing.
1.Steel Selection
In construction, steel is an indispensable material and contributes to the durability of the product. Criteria for selecting steel must be consistent with the design regulations in the commitment between the investor and the builder
2.Clean and rust steel.
Steel rust in the process of preservation, processing and erection before use has a great influence on the quality of construction works. Steel rust not only reduces the bonding force between the steel and the outer protective layer, but moreover it is also the cause of corrosion, premature structural destruction, especially for marine constructions.
Clean steel with wire brush or machine. Chemical treatment of steel rust. With steel only covered with dirt, just spray or wipe it with a wet cloth
3. Processing steel reinforcement.
When processing reinforcement, it must be in accordance with the structure and specified in the agreement
4.Strengthening erection.
This is a very important step, requiring very high accuracy. The protection layer of the reinforcement system is consistent with the design regulations for each member. The main steel frame needs a stable format, the right structure, to ensure safety.
Construction belt steel needs to be vertical, at the correct distance by measuring rod and marked with chalk on the steel for workers to tie the belt. This step requires workers to be meticulous, precise, the steel belt must arrange the points of interlaced cross hooks in accordance with the regulations.
5. Steel connection.
Connection length as specified by the design. Usually the length of the steel is shorter than the structure of the building. Therefore, people often have to join the steel and the welding method is the most advanced and used method.
6. Steel millet to create a protective concrete layer.
Sufficient strength, ensure the thickness of the steel protection layer. Steel millet needs to be precast to ensure that the construction is not broken. In the position of beams, there must be 2 spacers so that the steel frame is not distorted and stable.
7. Pouring concrete
During the concreting process, it is necessary to adjust the warped positions, which are not exactly as in the drawing to ensure the most accurate reinforcement system.
