Hollow floor built-in metal combined mandrel for improving fireproof grade
The invention discloses a hollow floor built-in metal combined mandrel for improving the fireproof grade. The hollow floor built-in metal combined mandrel comprises mandrel shell bodies. The mandrel shell bodies are formed by mechanically pressing metal materials, convex edges are arranged on the peripheral edges of the bottoms of the mandrel shell bodies, clamping devices are arranged on the convex edges, vertical through holes are formed at intervals, and transverse reinforcing ribs are arranged on the upper surfaces of the mandrel shell bodies at intervals. Mortises and tenons are arrangedon one mandrel, the two mandrel shell bodies are assembled into one mandrel through the cooperation of the mortises and the tenons, parts do not need to be assembled, the mounting process is simplified, the assembled parts are reduced, the cost is reduced, the fireproof grade of the metal combined mandrel reaches the grade A, when fire happens, combustion does not easily happen, no toxic gas is generated, and the requirements of hollow floor slab filler for fireproofing are well met.
本发明公开了一种提高防火等级的空心楼盖内置金属组合芯模，包括芯模壳体，所述芯模壳体由金属材料通过机械压制而成，该芯模壳体的底部四周边沿设有凸沿，该凸沿上设有卡合装置，并且间距开有垂直的通孔，所述芯模壳体上表面间距设置有横向加固筋条；本发明在一个芯模上即有榫槽，又有榫头，通过榫槽和榫头的配合将两个芯模壳体组装成一个芯模，无需装配零配件，简化了安装工序，也节约了装配零配件，降低了成本，并且该金属组合芯模防火等级达到A级，在发生火灾时，不易燃烧，并无毒害气体产生，很好地解决了空心楼板填充体对防火的要求。
