When the reliability appraisal of the steel structure confirms that it needs to be reinforced, the reinforcement design shall be carried out in accordance with the standards and regulations based on the appraisal conclusion and the requirements put forward by the property owner.
There are different degrees of roof leakage phenomenon after the metal frame warehouses are built and put into use, and the roof leakage has become a common quality failure of metal frame warehouses.
It is necessary to accurately grasp the straightness and distortion of the steel column, the distance from the connecting holes of the column and beam to the bottom of the column.
Steel structures are often used in various engineering structures with large spans, large heights, large loads and large dynamic effects, and have a wide range of applications. With the development of steel structure, its stability becomes more and more important.
Strengthen the review of construction drawings. The drawings are the basis for the construction of the project.
The slope of the light steel structure roof is generally small, often below 6%. In the rainy areas in Central South, the roof leakage of this structure is more common.
Steel structure workshops generally require large space due to process layout requirements. The structure usually adopts a frame structure, and frame-shear structure can also be adopted when the number of floors is large and the process conditions permit.
The design of the steel structure of the portal frame steel structure also has the economic span and the optimal spacing of the frame. When the process requirements allow, it is more economical to choose a small-span portal frame.
