Introduction of on-site construction process of steel structure workshop
The construction of the steel structure workshop is convenient, mainly reflected in that the steel components are pre-processed in the factory and can be assembled on site. The process generally includes: primary structure lifting → secondary structure lifting → roof panel and insulation layer installation → wall enclosure installation → Other details.
Let's talk about it in detail below.
Specific process:
1. Hoisting the main structure
Ground splicing steel beams, erecting steel columns, hoisting steel beams, connecting secondary structures, correcting main structure deviations, installing crane beams (optional), hoisting interlayers (optional), and fireproof coating. Main control quality: The deviation of the main structure should meet the specifications and design requirements, and the initial and final tightening of high-strength bolts should meet the requirements of the steel structure workshop.
2. Substructure installation
Roof purlins, roof wall supports, flange supports, etc.
3. Installation of roofing panels and insulation
Lay the insulation layer first, and then install the roof panel. (Some projects lay a layer of steel mesh under the insulation layer to prevent the insulation layer from falling off. This mainly depends on the insulation layer level.) Main control quality: the roof is mainly waterproof, so the billboard and The board is lapped and nailed. The glue coating is full and not full. The glued area should be cleaned. The coating on the surface of the board should not be damaged to prevent rust.
4. Wall enclosure installation
Mainly the installation of the wall insulation layer and wall panel of the steel structure workshop. Main control quality: The wall surface is mainly an aesthetic problem, and a window waterproof problem. There is also the problem of installation deviation, for example, the bottom should be flat, the entire plane should be flat, and the flatness deviation between the plates should meet the requirements.
5. Other details
It is mainly the installation of some trims, such as the corner between the roof and the wall, the corner at the corner of the wall, the floodboard between the wall panel and the brick wall, the edge of the door and window, etc. Main quality control: The detailed structure is the last link and one of the main items of the aesthetic project, so horizontal and vertical are the most basic.
