Calcium silicate boards (English: calcium silicate) as novel green and environment-friendly building materials have the advantages of excellent fire resistance, moisture resistance and super-long service life besides the functions of traditional gypsum boards, and are widely applied to suspended ceilings and partition walls of industrial and commercial engineering buildings, home decorations, liner plates of furniture, liner plates of billboards, shed plates of warehouses, network floors, wall plates of tunnels and other indoor engineering. Therefore, the calcium silicate board has good flame retardant and fireproof performance.
The decorative pattern of decorative pattern steel sheet is outwards, can play reinforcing joint strength between steel cylinder body and the concrete layer like this.
The two ends of the section steel, the steel bar or the bolt rod extend out of the steel cylinder body to provide support for the steel bar or the steel wire mesh, and the steel bar or the steel wire mesh is poured in the concrete layer to ensure that cracks cannot occur in the concrete layer.
According to the design drawing, the cross section of the steel cylinder body can be round, square, rectangular or regular N-shaped (N is a natural number more than or equal to 5), namely the cross section of the frame column is also the shape, so as to meet the requirements of different occasions.
To sum up, the utility model discloses principle science, modern design, simple structure, the prefabricated interior concrete column in cast-in-place in addition of steel concrete combination, structural strength is high, has shortened construction cycle, has reduced construction cost and has good fire behavior.
