Capacity requirements for steel structural components

Time:[2023-9-7]  Hits:2141

1. Requirements for filling in the capacity of each component of the steel structure:


(1) Component: piece;


(2) Basic and connecting nodes: pieces;


(3) Roof truss and truss: truss;


(4) Steel beams and columns: pieces;


(5) Steel platform: pieces;


(6) Railing: m;


(7) Steel ladder: running (explaining the steps of stairs);


(8) Purlins: pieces; Crane beam: truss;

 


2. Minimum sampling in inspection batch:


(1) 10% capacity and ≥ 3: basic inspection, etc

 


3. Full inspection in the inspection batch:


(1) Main structure size


4. Original record: Inspect the specific parts of the components and view the results


5. Inspection basis: "Code for Construction Quality Inspection of Steel Structures" GB50205-2020


(1) 10.2.1 The positioning axis, foundation axis and elevation of the building, and the specifications and fastening of anchor bolts should meet the design requirements. Inspection quantity: 10% of the columns should be randomly checked based on their base number, and no less than 3 should be included.


(2) 10.3.4 The allowable errors for the overall verticality and overall plane bending of the main structure of a single-layer steel structure comply with the rules in Table 10.3.4. View quantity: View all the main facades. For each viewed facade, in addition to two columns of corner columns, at least one column should be selected as the interval column.

 


6. What inspection batches are required for on-site welded steel structures: (The conventional practice should be combined with the design drawings)


(1) Quality inspection records of steel structure (steel structure welding) inspection batches;


(2) Quality inspection records of steel structure (common fastener connection) inspection batches;


(3) Quality inspection records of steel structure (high-strength bolt connection) inspection batches;


(3) Quality inspection records of steel structure (parts and component processing) inspection batches;


(4) Quality inspection records of steel structure (component assembly) inspection batches;


(5) Quality inspection records of steel structure (pre assembly) inspection batches;


(6) Quality inspection records of steel structure (single layer structure) inspection batch; (If it is a multi-layer structure, use multi-layer and high-rise structures for installation.)


(7) Quality inspection records of steel structures (pressed metal plates) inspection batches;


(8) Quality inspection records of inspection batches for steel structures (anti-corrosion coating);


(9) Quality inspection records of steel structure (fire resistant coating) inspection batches;

 


7. The on-site installation engineering of factory welding requires documentation; (The conventional practice should be combined with the design drawings)


(1) Quality inspection records of steel structure (single layer structure) inspection batch; (If it is a multi-layer structure, use multi-layer and high-rise structures for installation.)


(2) Quality inspection records of steel structures (pressed metal plates) inspection batches;


(3) Quality inspection records of inspection batches for steel structures (anti-corrosion coating);


(4) Quality inspection records of steel structure (fire resistant coating) inspection batches;

 


9. The content and examples of shadow inspection required for steel structure engineering:


(1) Example of filling in shadow inspection for steel structure bolt connection:


① Product certificate and inspection report for high-strength bolts used in steel structures.
