1, the material of the attic shelf, the quality of the material is the foundation, which determines the overall bearing capacity;

2, column span, the greater the column span, the lower the bearing capacity. If the long-span attic needs to improve its bearing capacity, it must increase the material specifications;

3. The distance between the cross beam and the supporting beam, the main bearing parts of the cross beam and the supporting beam seat, and the distance also affect its bearing capacity. To ensure the bearing capacity, the number of supporting beams cannot be easily reduced;

4. The material of the attic panel, generally speaking, in the case that the load-bearing requirement is not high 300-500 kg, you can choose the wooden attic panel. If the load-bearing requirements are high, steel gusset plates can be selected as attic panels;

5. The design and installation technology of the attic, and the professional design and installation of the attic are also important factors affecting the overall performance of the attic.

Generally speaking, the bearing capacity of attic shelves is related to many factors, and the scheme design of attic shelves must consider all kinds of engineering conditions.
