A funny Sichuan steel structure company

Construction points of Sichuan steel structure company:

1. Processing and cutting: lofting according to the construction drawing, the amount of welding shrinkage and processing allowance should be reserved when lofting and numbering, and the sample should be made according to lofting. Steel correction: Steel must be corrected before cutting, and the corrected deviation value should not exceed the allowable deviation value specified in the specification to ensure the quality of cutting. The hot-working section steel is first hot-working, and then the hole is numbered after cooling. Steel plate embedded parts and other parts cutting, drilling and spraying anti-corrosion paint treatment.

2. Measurement pay-off: measure the center line of the embedded part elevation according to the civil engineering elevation reference line, and check the elevation deviation and left and right deviation of the embedded part. Organize the results and determine the adjustment treatment scheme for embedded parts separation. The top elevation line of the embedded parts is determined along the outer edge of the floor slab.

3. Installation and treatment of embedded parts: locate the installation position of embedded parts, drill installation. It is required that the embedded parts are accurately located and firmly embedded. The elevation deviation is not more than 9mm, and the left and right displacement is not more than 20mm.

4. Suspension arm installation and welding: the suspension arm

installation adopts welding, and it is necessary to check the welding node, adjust the design slope of the suspension arm, and weld it accurately. After one suspension arm is accurately pulled over, install a suspension arm on the other side, and spot weld it after it is in place. Then, with these two suspension arms as the reference, pull out the highest and lowest elevation lines of the suspension arm, and weld the remaining suspension arms one by one. And weld seamless steel pipes. When the section steel needs to be connected, weld the head first and straighten. When using section steel joints, in order to make the joint section steel and the embedded parts of the steel plate closely fit, the flute angle should be shoveled according to the design requirements. The butt weld should be welded with an arc ignition plate at both ends of the weld, and its material and wave mouth type are the same as the weldment, and the gas cut is cut off and smoothed after welding.

5. Calibration inspection: After the suspension arm is installed, first check the quality of the on-site connection part. The installation quality of the suspension arm mainly checks the non-verticality of the vertical surface of the suspension arm; Pressure on the side of the vertical face of the suspension arm; Suspension arm slope. Ensure that the suspension arm meets the design stress state and overall stability requirements.

6. Connect the stressed cable: position the tie rod reference line and elevation line, install embedded parts according to requirements, and weld railings.

7. Stainless steel glass claw

installation and welding: pop up the longitudinal and horizontal lines and design elevation according to the design size, clamp with a fixture, carry out positioning spot welding, and weld the glass claw base after assembly.

8. Anti-rust spray paint treatment

: slag and splash should be removed, and the surface of stainless steel parts should be sprayed with white paint multiple times anti-rust spray paint treatment. The thickness of the paint and film should comply with the design requirements or the provisions of the construction specifications. The paint on the inside of the limb steel shall not be missed.

The analysis of the above points hopes that if you have questions, call Sichuan Steel Structure Company.
