The core method to improve the load-bearing capacity of attic style shelves Improving the load-bearing capacity of attic style shelves requires comprehensive optimization of structure, materials, technology, and usage standards. The core principle is to enhance the rationality of stress, disperse loads, and avoid local overload. The specific methods are as follows: structural optimization Upgrade the specifications of the main/secondary beams (such as increasing cross-sectional dimensions and shortening spans), increase the spacing between columns (such as reducing from 3 meters to 2 meters), add intermediate supports or strengthen rib plates to distribute stress. Material upgrade The main structure is replaced with high-strength steel (such as Q355 instead of Q235), and the platform panels are replaced with thickened anti slip steel plates; Upgrade the connecting bolts to high-strength bolts of grade 8.8 or above. Process enhancement The key nodes are designed with full welding and reinforced ribs, and the columns are fixed to the ground with chemical anchor bolts or concrete piers to ensure a secure connection without looseness. Foundation and Load Management Strengthen the ground (such as pouring concrete cushion layer+steel mesh), standardize the stacking of goods (avoid concentrated overloading, evenly distribute loads), divide the load-bearing zones and mark load limit warnings. Regular testing and reinforcement Regularly check the structural deformation, bolt tightness and corrosion, and timely replace or add auxiliary support (such as slant support) for weak parts. Through the above measures, the load-bearing capacity of shelves can be significantly improved while ensuring safety. It is recommended to combine professional design calculations to avoid blind modifications.
