Construction technology and matters needing attention of steel structure engineering company

Although the construction of steel structure engineering company is simple and fast, from design to installation, all links have to go through strict technical review.

I. Organize supervisors and technicians of construction units to review design drawings and technical specifications before the construction of steel structures, and do a good job of technical disclosure.

Ii. Ensure that the quality of steel structure members meets the design specifications, including the type of steel structure, rust removal, rust prevention, welding quality, etc.

Three, according to the design needs, the foundation for anchor bolts embedded, and then concrete pouring.

Iv. Site hoisting: According to the construction technology of "column before beam, down after up, middle to both sides", the steel column shall be hoisted first. When the column and anchor bolts are separated by 30cm, the bolts shall be tightened after manual lifting to complete the installation of steel column; Then the lifting of the steel beam, and finally the lifting of the beam.

Five, the lifting structure is corrected, the derrick hammer is used to correct the steel column, and the inclined steel column is corrected with gaskets; Calibrate the steel beam with a level, then with a jack and chain back.

Six, construction safety, because the steel frame lifting is a highly difficult work, is the cooperation between people, therefore, the construction personnel should wear safety helmet, and to carry out lifting under the guidance of the safety person in charge.

Steel structure is an important raw material of steel structure, it has good plasticity and toughness, the seismic performance of the whole steel structure is optimized, so as to improve the service life of the steel structure. Under the action of external force, brittle fracture does not occur when steel structure deforms. At the same time, the deformation of the deformed part can be restored to the original state by using the flexible connection method, and the seismic performance of the whole structure can be improved. Crack resistance. Due to the influence of temperature, brick and concrete structure of the house is prone to crack, crack in the wall structure, its heat insulation, waterproof and other performance will be seriously affected, resulting in the overall life shortened. In contrast, the steel structure has better crack resistance, which can share the load of the wall and reduce the occurrence of cracks. Compared with the traditional wood structure, the corrosion resistance of steel structure has been significantly improved. According to relevant data, the corrosion resistance of steel structure is about 1.5 times that of brick-concrete structure, and it has better heat insulation performance. Typically, steel structural parts are manufactured in advance and shipped to a designated location for assembly. The entire assembly process is completely automated, which makes the construction process more convenient and can ensure the safety of the project.
