Generally speaking, the large construction process mainly includes the following five points:

 1. Hoisting of main structure, 2. Installation of secondary structure, 3. Installation of roof panel and insulation layer, 4. Wall maintenance and installation, 5. Detailed structure.The following is the detailed analysis and

introduction of steel structure company:

 　   1.Hoisting of main structure: splicing steel beams on the ground, erecting steel columns, hoisting steel beams, connecting the secondary structure, correcting the deviation of main structure, installing crane beams (optional), hoisting interlayer (optional), fireproof coating.Main control quality: the deviation of main structure shall meet the specification and design requirements, and the initial and final tightening of high-strength bolts shall meet the requirements.

 　　2.Secondary structure installation: roof wall purlin, roof wall support, flange support, etc.

 　　3.Installation of roof panel and thermal insulation layer: first lay the thermal insulation layer, then install the roof panel (in some projects, lay a layer of steel wire mesh under the thermal insulation layer to prevent the thermal insulation layer from falling off, which mainly depends on the level of the thermal insulation layer). The main control quality is that the roof is mainly waterproof, so the shall be overlapped with the board, and the nailing shall be carried out. The glue coating shall be full and not full, and the gluing place shall be wiped clean,The coating on the surface of the plate shall not be damaged to prevent rusting, etc.

 　　4.Wall maintenance and installation: mainly wall insulation layer and wall panel installation.Main control quality: the wall is mainly a beautiful problem, and a window waterproof problem.There is also the problem of installation deviation.For example, the bottom should be flat, the whole plane should be flat, and the flatness deviation between plates should meet the requirements, etc.

 　　5. detail structure: mainly some trimming installation, such as the corner between the roof and the wall, the corner between the wall, the flashing between the wall panel and the brick wall, door and window trimming, etc.Main control quality: the detailed structure is the last link, and also one of the main aesthetic items, so horizontal and vertical is the most basic.
