Steel structure works: preparation before installation
Organize the engineer to prepare the installation organization design document of the steel structure project and submit it to the supervising engineer for confirmation and signature. Before construction, formulate the labor allocation scheme and supporting scheme for mechanical equipment, and confirm whether the access road for steel structure materials is smooth. Make material input plan.
Deployment of temporary facilities. The management personnel enter the site, organize personnel to enter the site, complete the handover procedures with the civil steel structure project, require the civil contractor to provide the baseline, and sign after the acceptance and confirmation of both parties. Sets the baseline, level, and modification level. Enter the normal construction procedure.
Steel structure engineering posts include piling workers, sheet metal workers (or cold working workers), welders, fitters, hoisters, scaffolders, sheet metal workers (or cold working workers), including welders.
Steel structure engineering.
Steel structure installation is a kind of steel structure and one of the main types of building structures. Steel structure engineering is one of the common structural forms in modern building engineering.
Steel structure is gradually becoming a common product in society, such as steel structure workshop, steel platform, floor extension, etc. It is becoming an indispensable part of society. Due to the safety of steel structure construction and the characteristics of steel, steel structure engineering has entered an era of rapid development. Steel structure construction process. Because it is essential.
During the construction of Huizhou steel structure, it is necessary to protect the original structure from damage and ensure the long-term safety of the new structure. From the perspective of safety science and economics, the main process of steel structure construction includes construction preparation, material procurement, site construction and site closure.
Steel structure building.
Construction preparation.
1. Structural inspection.
According to the tentative blueprint for steel structure construction, remove the plastering layer on the surface of the original structure and check whether the blueprint is consistent with the actual situation. Then complete the plan before determining the steel formwork.
2. Material preparation.
3. Site construction.
4. Measurement and setting.
Locate and set the line according to the blueprint, and determine the size of the embedded position and the range of the deletion position.
5. Anchor note
Embedded parts are fixed on the original structure with chemical bolts. During steel structure construction, the structural surface of the embedded steel plate at the end of the main steel beam shall be polished flat, and other irregular parts shall be treated as appropriate. The design position of embedded parts shall be aligned with the prototype steel, drilled and cleaned. Chemical anchors can only be implanted after drilling, and chemical bolts can only be moved after fully curing.
6. Embedded installation.
According to the actual position of the chemical bolt hole, drill and paste the embedded steel plate on the embedded steel plate and angle steel (section steel). Other embedded parts are installed on the supports between beams.
7. Anti rust treatment.
After the materials arrive, all steel structure building materials shall be coated with anti rust paint and dried.
8. Special shaped steel processing.
By re measuring the dimensions of the steel structure construction site in Huizhou, processing the section steel and removing the coating at the weld, the installation can be accurate at one time to ensure the weld quality. 9. Installation of main beam.
The main steel beam is welded to the embedded steel plate according to the positioning position of the line, and the steel beam is horizontal and flat. The key to the construction scheme is the construction scheme, useful materials and the construction process of the engineer.
The required personnel are professional constructors, professional engineers, professional quality inspectors, professional safety managers, inspectors, riveters, cranes, firemen, welders (masters of submerged arc welding and co welding). Hoisting, welding and welding have special work permits, and riveters need separate drawings and piles. This is very useful for the verification and revalidation of technicians.
