. Advantages of Floor Slabs
. . < The steel structure mezzanine floor is light in weight, reducing the building load and foundation investment.
. . < The thickness of the steel structure mezzanine floor is thin, generally < r< which expands the building space.
. . < The steel structure mezzanine floor has high density, so it is extremely strong and can bear more than < r3< tons per square meter.
. . < The fireproof performance of the steel structure mezzanine floor is particularly good, the fire resistance time is long, and it is a new type of floor material that is < r< class non-combustible.
. . < The thermal conductivity of the steel structure mezzanine floor is low, and the house has good thermal insulation effect, which reduces energy consumption.
. . < The steel structure mezzanine floor construction is simple and fast, and the overall cost is low. Construction produces very little waste, which helps protect the environment.
< . . . Construction methods of floor slabs
. . < According to the different spans of the building, the calculation of static load and dynamic load, select reasonable profiles and design the main and auxiliary beams The spacing allows for a better and reasonable selection of fiber cement pressure panels.
. . < The arrangement and welding of profiles during the construction of fiber cement pressure plates must comply with the drawing design requirements. The weld strength and welding quality must meet the standard requirements of < /-<. The welds on the contact surface with the fiber cement board should be Grind it smooth before laying the boards to remove any spatter during welding.
. . < The thickness of the fiber cement board selected varies depending on the span of the building, the size of the load, the spacing of the support beams, etc. However, according to the national building materials specifications, the fiber cement board selected must be a high-density fiber cement board. , the density is greater than < r./3< and the flexural strength (air-dry state) should be greater than < The beams should be placed parallel to each other, and the edges of the joints between the boards should fall on the same beam. The seams between the boards should be sealed with silicone glue.
. . < No edge of the fiber cement board shall be suspended
. . < The length of the self-tapping nails used for fixation shall be the thickness of the board plus < r The center of the hole should be about < r< from the edge of the plate.
. . < Because the kitchen and bathroom are considered to be waterproof layers, and the area is small, the static and dynamic load requirements are slightly smaller, so the thickness of the board can be slightly thinner, and the model of the profile selected can also be judged accordingly. .
