People who have a little knowledge of loft steel structure floor all know that loft steel structure floor can be seen in loft apartments, double story houses and villa projects we bought. Loft steel structure floor plays the role of floor of compound floor. Loft steel structure floor should be built with light steel keel. There are strict requirements in the design and construction. How to weld and how to smooth it Certain will, let's make up for you to introduce one by one.

1. According to the different span, static load and dynamic load of the building, select reasonable profile, plan the distance between main and auxiliary beams, and select loft steel structure floor better and reasonably.

2. During the construction of loft steel structure floor, the placement and welding of profiles are necessary to meet the requirements of the drawing planning. The weld strength and welding quality must meet the specification requirements of GB / t5185-1985. The welding joints on the contact surface of loft steel structure floor should be smoothed before the slab laying to clear the spatter during welding.

3. The thickness of loft steel structure floor slab is also different according to different construction span, load size and support beam distance. However, according to the national building material specification, it is necessary to select loft steel structure floor with high density, with density greater than 1.8g/cm3 and flexural strength (air dry condition) greater than 28Mpa.

4. The longitudinal and transverse resistances of the high-density loft steel structure floor are slightly different. Therefore, the longitudinal direction of the slab should be parallel to the main beam, and the edge of the joint between the plates should fall on the same beam, and the joints between the plates should be filled with silicone glue for sealing.

5. No edge of loft steel structure floor slab shall be suspended;

6. The length of the self tapping screw for fixing is the thickness of the plate plus 30-35mm, and the distance between the nails is between 300-600mm. The distance between the center of the nail hole around the plate and the edge of the plate should be about 20mm.

7. In kitchen and toilet, due to the consideration of waterproof layer, smaller area and smaller static and dynamic load requirements, the thickness of the board can be slightly thinner, and the type of profile selected can also be identified accordingly.
