What kind of workers are needed for steel structure engineering?

Types of steel structure engineering include:? Lofting workers, sheet metal workers (or cold workers), welders, fitters, Rigger, scaffolder, sheet metal worker (or cold worker), welder.

Steel structure engineering is a structure with steel as the main material, and it is one of the main types of building structures. Steel structure is one of the common structural forms in modern architectural engineering. The famous cable bridge of Dadu River in Luding, Sichuan, Yuanjiang Bridge in Yunnan and Panjiang Bridge in Guizhou are all examples of early iron load-bearing structures.

The coating thickness of different types of coatings shall be tested by the following methods:

1, paint film thickness, available paint film thickness gauge detection, the number of sampling components should not be less than the minimum capacity of class A samples in the standard table, and should not be less than 3 pieces; Each piece is measured at five positions, and the value of each position is the average of the dry paint film thickness of three measuring points 50mm apart.

2. The coating thickness of thin fire retardant coatings can be detected by coating thickness tester, and the measurement method should comply with CECS24 "Technical Specification for Application of Fire Retardant Coatings for Steel Structures".

3. The coating thickness of thick fire retardant coating shall be detected by measuring needle and steel ruler, and the measuring method shall comply with the provisions of Technical Specification for Application of Fire Retardant Coatings for Steel Structures CECS24.

The thickness value and deviation value of coating shall be evaluated according to Code for Acceptance of Construction Quality of Steel Structure Engineering (GB50205). According to the Code for Acceptance of Construction Quality of Steel Structures (GB50205), the appearance quality of coatings can be inspected and evaluated according to different materials.

Extended data:

In the construction of building engineering, the design of steel structure engineering can not only make the building engineering have a larger span space, but also have the advantages of convenient installation and low cost, so it is widely used in building engineering.

With the further development of urbanization in China, the number of high-rise buildings will increase sharply, which puts forward higher requirements for the design of steel structure engineering.

Steel structure engineering has the following advantages:

Seismic 1: The roofs of low-rise villas are mostly sloping roofs, so the roof structure is basically a triangular roof truss system composed of cold-formed steel members. After the structural plate and gypsum board are sealed, the light steel members form a very strong "plate-rib structure system", which has stronger seismic and horizontal load resistance, and is suitable for areas with seismic intensity above 8 degrees.

2. Wind resistance: I-shaped steel structure building has light weight, high strength, good overall stiffness and strong deformation resistance. The weight of the building is only one-fifth of that of the brick-concrete structure, which can resist the hurricane of 70 meters per second and effectively protect life and property.

Durability: The residential structure of light steel structure is all composed of cold-formed thin-walled steel members, and the steel skeleton is made of ultra-anticorrosive high-strength cold-rolled galvanized sheet, which effectively avoids the influence of steel plate corrosion during construction and use, and increases the service life of light steel members. The structural life can reach 100 years.

4 insulation: the insulation material used is mainly glass fiber cotton, which has good insulation effect. The insulation board used for the external wall can effectively avoid the "cold bridge" phenomenon of the wall and achieve better insulation effect. The thermal resistance of R 15 thermal insulation cotton with a thickness of about 100mm can be equivalent to that of a brick wall with a thickness of1m.

5. Sound insulation: Sound insulation effect is an important index to evaluate a house. The windows installed in the light steel system are all made of insulating glass, which has good sound insulation effect, and the sound insulation reaches more than 40 decibels; The sound insulation effect of the wall composed of light steel keel and thermal insulation gypsum board can reach 60 decibels.

6. Health: Dry construction can reduce the environmental pollution caused by wastes, and the building steel structure materials can be recycled by 65,438+000%, and most other supporting materials can be recycled, which is in line with the current environmental awareness; All materials are green building materials, which meet the requirements of ecological environment and are beneficial to health.

Comfort: Light steel wall adopts high-efficiency and energy-saving system, which has breathing function and can adjust indoor air humidity; The roof has ventilation function, which can form a flowing air chamber above the house to ensure the ventilation and heat dissipation requirements inside the roof.

8. Fast: Do all your homework, regardless of the environmental season. A building of about 300 square meters needs only five workers for 30 working days to complete the whole process from foundation to decoration.
