Analysis of installation steel engineering process

Analysis of steel installation process

1. Hoist the main structure: splicing steel beams with ground data, erecting steel columns, hoisting steel beams, connecting secondary structures, and correcting market entities If there is a deviation in the economic structure, the installation uses the crane beam (optional), the hoisting interlayer (optional), and the fire protection paint coating. High-strength steel should be studied in the production of steel structures in the iron sheet workshop to greatly improve its yield point strength; in addition, new types of steel should be rolled, such as H-beam (also known as wide-flange steel) and T-shaped steel and profiled steel plates to adapt to large Span structures and super high-rise buildings are required. The characteristics of steel plant production are high strength, light weight, good overall rigidity and strong deformation ability, so it is especially suitable for the construction of large-span and super-high and super-heavy buildings; the material is uniform Good quality and isotropy, it is an ideal elastic body, and it is the basic assumption of general engineering mechanics; the material has good plasticity and toughness, can have large deformation, and can withstand dynamic loads well; construction period is short; its degree of industrialization It can carry out specialized production with a high degree of mechanization. Steel structure engineering is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of beam steel, steel column, steel truss and other components made of section steel and steel plate, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, washing and drying, and galvanizing.

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..

2. Install the secondary structure: roof wall purlins, roof wall environmental support, flange support capacity, etc.

3. Install the roof panel and insulation layer: first lay the insulation layer, then install and install the roof panel (some projects also lay a layer of steel mesh under the insulation layer to prevent The insulation layer material falls off, which mainly depends on the technical level of the insulation layer)

Main control quality: the roof is mainly waterproof, so it depends on the overlapping of the board and the board, nailing If the glue is not full, the glue should be wiped clean, and the coating of the board should not be damaged to prevent rust, etc.

4. Maintain the wall yourself Installation: The main problem is wall insulation and wall panel installation.

Mainly by controlling the quality of work: the wall is mainly as an aesthetic issue, and an important window place waterproof issue. And we are the installation deviation analysis problem. For example, the bottom should be flat, the entire plane should be flat, and the flatness deviation between the plates should meet the design requirements of students and so on.

5. Detail structure: mainly the installation of some decorative edges, such as the corner between the roof and the wall, the corner of the wall, between the wall panel and the brick wall. between the flashing board, the decoration of doors and windows, etc.
