What are the construction processes of the tension film shed?
The membrane shed has appeared more and more in our life. Do you know what the construction process of the car shed has? The following details are introduced:
1. Preparation and blanking of processing
According to the construction drawing, welding shrinkage and machining allowance shall be reserved during setting out and material number, and the setting out shall be taken as an example. Steel correction: steel must be corrected before blanking, and the deviation after correction shall not exceed the allowable deviation value specified in the specification to ensure the quality of blanking. The hot processed section steel is hot processed first, and then the hole is numbered after cooling. Cutting and drilling of embedded parts and other parts of steel plate and spraying anti-corrosion paint.
2. Survey setting out
Measure the elevation center line of embedded parts according to the civil elevation datum line, and search and check the elevation deviation and left and right deviation of embedded parts. Rectify the consequences and determine the adjustment and treatment plan for the separation of embedded parts. The top elevation of embedded parts shall be determined by the ink line rising along the outer edge of the floor.
3. Installation and treatment of embedded parts
Position the installation position of embedded parts and drill and install. It is required that the embedded parts should be located accurately and firmly. The elevation deviation shall not be greater than 9mm, and the left and right displacement shall not be greater than 20mm
4. Installation and welding of suspension arm
The suspension arm is installed by welding. It is necessary to search and inspect the welding joints, adjust the design slope of the suspension arm, and then welding can be carried out without error. After one side suspension arm is correct, install the other side suspension arm, and spot weld after it is in place. Then, the two suspension arms are used as the benchmark to pull out the height and bottom line of the suspension arm, and then weld the spared suspension arm. And welded seamless steel pipe.
When the section steel needs to be extended, it shall be discussed and straightened by welding. When using section steel for discussion, to make the embedded parts of the steel and the steel plate close to each other, the angle of the corrugated should be removed according to the design requirements. The butt weld shall be welded with arc striking plate at both ends of the weld, whose material and wave port type are similar to the welding parts. After welding, the gas cutting shall be cut and ground.
5. Calibration inspection
After the installation of the suspension arm, first check the quality of the connecting parts on site. The installation quality of suspension arm mainly checks the verticality of the vertical surface of the suspension arm; the side of the vertical plane of the suspension arm is sagging under pressure; the slope of the suspension arm. Ensure that the suspension arm meets the design stress condition and overall stability requirements.
6. Connecting the cable
Locate the reference line and elevation line of the tie rod, install the embedded parts and weld the block as required.
7. Stainless steel glass claw installation and welding
Pop up the vertical and horizontal lines and design elevation according to the design dimension, clamp them with clamps, carry out spot welding, and weld the glass claw base after assembly.
8. Rust proof and painting treatment
Slag and splashes shall be removed. The surface of stainless steel parts of canopy shall be coated with white paint for multiple antirust and spray paint. The thickness of coating and film shall meet the design requirements or construction specifications. The paint on the inside of section steel shall not be missed.
9. Manufacturing and installation of laminated glass
Determine the glass size, horizontal and vertical position according to the design requirements and the measured dimensions, and the manufacturer shall process and manufacture. Install stainless steel glass claw, adjust the glass after temporary fixing, adjust the standard horizontal, vertical and plane. The deviation shall not exceed the specified deviation.
10. Adjustment inspection
The point glass shall be inspected for overall adjustment and adjustment, and the standard horizontal, vertical and plane shall be adjusted. The deviation shall not exceed the specified deviation.
11. Glue up and down
Clean the cracks between glass and the sunshade with film layout without water, oil stains, paint, rust, cement mortar, dust, etc. Clean the bonding surface thoroughly and dry it. In order to adjust the depth of the seam, avoid three side glue.
Protect glass from pollution by applying protective adhesive paper on both sides of seam. Apply sealant up and down at the same time. After injecting glue, smooth the surface of the glue joint to remove the excess glue. After glue injection, tear off the protective paper and wipe the glass with solvent if necessary. Do not stain dust and scratches until the glue is not completely tough.
12. Repair inspection: local repair inspection.
13. Clean up site: protect and clean the site.
14. Completion acceptance: completion acceptance.
