1. Preparation before construction
A series of preparatory work is required before the construction of steel structures and profiled plates:
1. Determine the construction plan and construction drawings, and formulate the construction plan in advance.
2. Determine the construction site, and survey and level the site.
3. Determine the construction personnel and material allocation, including lifting machinery, tools, labor, etc.
4. Arrange the passage and stacking location of vehicles and materials entering and leaving the site to ensure the smooth flow of roads at the construction site.
5. Conduct safety inspections, including assessment of the foundation, foundation and surrounding environmental conditions of the construction site, inspection of the safety performance of cranes, tools and facilities, and safety education and training of construction personnel.
Second, the construction process
1. The construction process of the steel structure
(1) Install the main beam: install the main beam on the prefabricated bearing, install and adjust it by crane, and use a forklift to support it at the same time to ensure the stable installation of the main beam.
(2) Install the secondary beam: install the secondary beam above the main beam, fix it through the bracket, and use a jack to adjust it until the secondary beam is perpendicular to the main beam.
(3) Install the column: Place the column on the foundation, and also use a crane to install and adjust it, ensure that the column is perpendicular to the foundation, and at the same time use temporary support for fixation.
(4) Welding connection: welding is carried out at the connection of the main beam and the secondary beam to ensure that the connection is firm.
(5) Installation of roof and wall panels: After the erection of the steel structure is completed, the installation of profiled plates and color steel tiles is carried out.
2. The construction process of the profiled plate
(1) Measurement: Before construction, it is necessary to measure the wall surface to determine the length, quantity and blanking size of the panel.
(2) Blanking: Blanking the plate according to the measured size to ensure that the size of the plate accurately meets the requirements.
(3) Installation: Install the plate on the wall and fix it by installing the fixture to ensure that the plate is firm and stable.
(4) Caulking: fill the gaps in the plates, and use caulkin or silicone to fill to ensure that there is no gap between the plates.
(5) Test: After the completion of construction, the test of the profiled plate is carried out to check whether the waterproof performance and durability of the plate meet the requirements.
3. Safety precautions
1. Special safety signs and warning signs should be set up on the construction site to ensure the safety of the construction site.
2. Construction personnel should receive safety education and training before arriving at their posts, and have relevant certificates and qualifications.
3. When carrying out lifting operations, lifting machinery that meets the requirements should be used, and professional drivers and assistants should be equipped.
4. When carrying out the construction of the profiled plate, attention should be paid to the reasonable placement and fixation of the plate to avoid the collapse or falling off of the plate.
5. The construction site should be kept clean, and hazardous waste should be cleaned up in time to avoid accidental injuries such as falls.
【Conclusion】
The construction of steel structure and profiled plate requires detailed preparation and construction plan, and also needs to pay attention to safety issues.
