How to control the quality of steel structure construction?

As a residential building with load-bearing beams and columns, steel structure houses not only beautify the environment, but also consolidate the application of houses in residential buildings. People's lives and wealth are guaranteed, and steel houses are truly separated from nature.

Manufacturing steel structure components in the factory, reduce the workload on site, shorten the construction period, meet the requirements of industrialization, not only save resources, but also reduce some unnecessary pollution; Steel structure factory manufacturing quality is reliable, accurate size, convenient equipment, easy to cooperate with related parts; Light weight, high strength. The weight of the house built with steel structure is about 1/2 of the weight of the reinforced concrete house; In order to meet the needs of large houses, the use area is about 4% higher than that of reinforced concrete houses. ; Steel can be recycled and less polluting to the environment during construction and demolition. These advantages lie in the value of steel houses. He uses these advantages to support his life "safe umbrella"; Safe and reliable, seismic, wind resistance performance is good, strong load capacity, seismic capacity up to eight, the big earthquake does not fall in the earthquake does not damage is its style.

Concrete columns are usually used for the roots of steel structures. The steel bars and formwork with unsightly roots were constructed in the same way as other projects. The insertion of the bolt into the root column is a top priority for quality control. The deviation of height spacing between each bolt and each group of bolts directly affects the overall quality of the project.

Before the steel structure is painted, there shall be no foreign bodies on the appearance of the components, and the number and thickness of the coating shall comply with the relevant regulations. In the supervision construction process, the construction personnel are required to fix the column on one side of the steel window first, and after the vanadium window is completely fixed in place, the column on the other side is welded to ensure that there is no gap between the steel window and the column. After the color plate is pressed into the site, stop the inspection and check the accuracy of the steel component device related to the construction device; Remove the welding coating and spatter during the purlin installation, apply anti-rust paint, and stop the anti-corrosion treatment of steel components. When installing the color plate, it should be stopped in the order of the wall, stopped from one side of the wall, and then fixed with screws, and the joint of the wall plate should be waterproof.
