Installation standards for steel structure engineering

Steel structures are widely used in the construction industry. Steel structure workshops are the first choice of many entrepreneurs because they can store a large number of products. The SAFS steel structure manufacturer will take you to understand what the engineering installation standards are.

 

1. Marks should be set at the end of the steel to indicate the specification, grade, quantity and material acceptance certificate number of the steel;

 

2. When stacking in the open air, the site should be flat, higher than the surrounding ground, and drainage ditches should be set around;

 

3. When stacking, try to make the back of the section steel face upward or outward to avoid snow and water accumulation. There should be a height difference at both ends to facilitate drainage;

 

4. Before installation, the construction unit should conduct special inspections on the product qualification certificates, design documents and pre-assembly records of the components, and review and record the dimensions of the components;

 

5. Appropriate connection methods should be adopted to make the joint design consistent with the simplified structural calculation model;

 

6. When hoisting the steel structure, appropriate measures should be taken to prevent excessive bending and torsional deformation, and heat blocks should be placed at the contact between the rope buckle and the component to prevent damage to the component;

 

7. After the steel structure is hoisted in place, the brackets and other connecting parts should be fastened in time to ensure the stability of the structure;

 

8. When using tools at high places, spare parts should be put into the tool bag, and they should not be thrown up and down;

 

9. When working in rainy days, reliable anti-skid measures should be taken, and lightning protection should be paid attention to during thunderstorm seasons;

 

10. Before construction, the weather conditions are good, and no work is allowed if the wind is above level 4.

How to control the quality of bolted connection construction of steel structure engineering? The high-strength bolt connection project is also one of the most important sub-items of steel structure engineering, and it is also one of the weak links in the current construction quality, mainly in:​

(l) Some high-strength bolts are shoddy (replace high-strength bolts with ordinary refined bolts);

(2) The surface treatment of high-strength bolts does not meet the requirements of the specification, including surface treatment, leveling and closeness, and quality of bolt holes;

(3) The tightening of high-strength bolts is not carried out according to the specifications. For example, the initial tightening and final tightening are completed at one time, no torque wrench is required, and it is entirely based on subjective estimates.

In order to ensure the construction quality of the high-strength bolted connection project, the supervising engineer must have a high sense of responsibility. While urging contractors to improve quality awareness, strengthen quality management, and implement quality assurance measures, work methods such as side-by-side supervision and parallel inspection are actively adopted. Only in this way can the construction quality of the high-strength bolted connection project be under strict control.
