　　The durability of steel frame lightweight plates requires that under normal maintenance conditions, the structural performance of the plate does not undergo serious deterioration, corrosion, detachment, carbonization, and the steel frame and internal cold drawn low-carbon steel wire mesh do not rust, achieving the expected service life of the design. Steel frame lightweight plates will undergo deformation under short-term, long-term, and repeated loading, as well as shrinkage and volume deformation due to changes in temperature and humidity. A comprehensive solution must be taken from the core material. The steel skeleton lightweight board core material is mainly composed of foamed concrete, ensuring that the skeleton must be protected by 20mm foamed concrete. And the deflection of the lightweight steel frame plate cannot reach 1/50 of the plate span, the cracks in the core plate cannot exceed 1.5mm, the cold drawn low-carbon steel wire mesh cannot be severely twisted and deformed, the core plate cannot undergo oblique compression failure, and the main ribs of the steel frame cannot undergo brittle failure. One of them is the insulation effect. Unlike other materials used for enclosure, their insulation properties can provide long-lasting insulation for the enclosed space during space enclosure. For example, in factory buildings, they can ensure a suitable temperature inside the factory.

　　The second is the sound insulation effect. The sound insulation effect of steel frame lightweight panels comes from their strength and thickness, as well as their composite core material's ability to absorb sound volume. This special performance is a good condition for quieting the enclosed space, and for workers, it is also a good condition for having a quiet space.

　　(1) Transport the board to the floor using an elevator, and then manually transport it to the working floor for installation in sequence.

　　(2) When installing the floor slab, the length of the slab placed on the support shall not be less than 40mm. After being in place, the main ribs of the floor slab should be firmly welded to the support (embedded parts on the concrete beam); The overlapping length and gap at both ends of the board should be uniform. If there are gaps at the support, iron sheets should be used to plug them, and then welding should be used to fix them

　　(1) The steel skeleton is connected by welding, and the quality grade of the weld seam during welding is. Each board shall be welded at least three points to the support (embedded part) on the steel frame (at least two points at the end). When installing the sandwich floor slab, the length of the board placed on the support shall not be less than 40mm. After the floor slab is in place, the main rib of the floor slab shall be welded firmly to the support (embedded part on the concrete beam), and the length of the weld seam shall not be less than 40mm.

　　(2) Unauthorized openings are not allowed on mezzanine floor slabs. When the size of the opening is d>; When it is 200mm, it should be designed separately and reserved in advance during production. In special circumstances, when opening holes on site, the manufacturer should cooperate to complete it. After the installation of the embedded parts is completed, measurements should be taken, and the allowable positional deviation of the embedded parts is required to be ± 10mm in the vertical direction and ± 5mm in the horizontal direction.

　　(3) The supports on the steel beams shall be welded according to the arranged dimensions and shall not be welded under load after installation.

　　(4) The support bracket connected to the concrete wall can be adjusted appropriately when drilling due to the influence of steel bars on hole formation, and the standard support bracket in the diagram can be modified accordingly.

　　(5) Before the production of steel components, their surfaces should be sandblasted for rust removal, and the quality level of rust removal should meet the national standard; Sa2 level standard.

　　The advantages of matching lightweight steel frame plates with steel structures are obvious

　　1. Steel frame lightweight slab is a steel frame structure that is highly reliable in connection with steel beams and has strong overall integrity.

　　2. The construction is simple and fast, greatly shortening the construction period.

　　3. It can achieve flat connection with steel beams and reduce the floor height.
