1.该板型板底平坦、腹板贴合,可根据各种房间的不同功用和需求供应多种板底天花处理方式。
1. The plate bottom of the plate type is flat and the web is fitted. A variety of plate bottom and ceiling treatment methods can be provided according to the different functions and needs of various rooms.
2.楼承板闭口截面重心距板底16mm左右,小于开口型或缩口型楼承板截面参数,按塑性理论分析组合楼板结构承载力时,混凝土压力合力中心与拉力合力中心具有更大的内力臂,这表明资料强度发挥更充沛,因而闭口组合楼板具有更大的结构承载力或者说具有更高的安全系数;
2. The center of gravity of the closed section of the floor bearing plate is about 16mm away from the bottom of the plate, which is less than the section parameters of the open or shrinkage floor bearing plate. When the bearing capacity of the composite floor structure is analyzed according to the plastic theory, the concrete pressure resultant force center and tension resultant force center have a larger internal force arm, which indicates that the data strength is more abundant, Therefore, the closed composite floor has greater structural bearing capacity or higher safety factor;

3.闭口楼承板能够彻底代替楼板中正弯矩受拉钢筋而且无须喷刷防火涂料即可抵达2小时的耐火时效;
3. The closed floor bearing plate can completely replace the tensile reinforcement with positive bending moment in the floor slab, and can reach the fire resistance aging of 2 hours without spraying fireproof paint;
4.闭口楼承板肋角使混凝土对楼承板的握裹力更强,组合楼板抵达实在的组合效果;
4. The rib angle of the closed floor bearing plate makes the concrete have a stronger grip on the floor bearing plate, and the composite floor slab achieves a real combination effect;
5.闭口楼承板组合楼板能够减小楼板厚度,增大净空高度。选用开口楼承板,小板厚需126mm,而选用该板型小只需104mm;
5. The closed floor bearing plate composite floor can reduce the floor thickness and increase the clearance height. Open floor bearing plate shall be selected, and the thickness of small plate shall be 126mm, while the minimum thickness of this plate type shall be 104mm;
6.闭口楼承板一同的卡槽悬吊体系能为建筑物板底机电管道设备供应便当,该体系无需在板底打眼或预埋铁件,只需轻松将两只卡片刺进板底沟槽内,便可供应200kg吊重吊点,拆开也很便当;
6. The card slot suspension system together with the closed floor bearing plate can provide convenience for the electromechanical pipeline equipment at the bottom of the building plate. The system does not need to drill holes or embed iron parts at the bottom of the plate. It can provide 200kg lifting points by easily inserting two cards into the groove at the bottom of the plate, and it is also easy to disassemble;
