Steel skeleton light trestle plate is a kind of composite plate, set load-bearing, heat preservation, waterproof, fireproof, anti-corrosion and other functions in one of the new building components, the benchmark period of component design is 50 years, in the structural design, we fully consider the static and dynamic action of the component, the role of permanent load and the role of variable load and accidental load. With the advantages of light weight, strong bearing capacity, good thermal insulation effect, less wet operation, fast construction speed and short construction period, it has been widely used in the coal industry, metallurgical industry, electric power and chemical industry, and has been recognized and praised by the construction unit. It is widely used in Shanxi, Henan, Ningxia, Shaanxi, Inner Mongolia, Shandong and Xinjiang. Steel skeleton light plate
The trestle slab is subjected to a point load.
The trestle slab bears the uniform load on the basis of a little load (concentrated load), then at this time we will consider the position of the concentrated load as a support, the general trestle slab should not bear the point load of more than 800kg, the point load is also a temporary load, and the final stress system is still the main structure. The corresponding rib selection must be checked.
1. Reduce the amount of steel used.
So as to reduce the difficulty of steel structure construction and further reduce the overall construction period. It can be seen that the adoption can minimize the construction period, reduce the difficulty of construction, and realize value for users.
2. The construction period is short.
Due to the factory prefabrication, the plate can be hoisted and fixed on site, and the construction is simple and fast.
3. Reduce construction processes.
Due to the engineering prefabrication production, the flatness of the board surface is good, and it can no longer be used as a leveling layer.
4. The floor height is objectively increased.
Because the plate can be flattened with the steel beam, the plate surface can be flat with the upper edge of the steel beam, which can minimize the occupation of the indoor floor height.
5. Increased seismic performance.
Considering from the aspect of building seismic resistance, adopt trestle plate to reduce building self-weight, and adopt rigid connection between plate and plate, integrity is good, is very conducive to improving building seismic performance.
