Multifunctional compound fireproof densely-ribbed floor mandrel

The invention discloses a multifunctional compound fireproof densely-ribbed floor mandrel. A fireproof rock wool layer is compounded on the lower surface of a mandrel body, a GCR material layer is compounded under the rock wool layer, the mandrel body is a flame-retardant EPS material body, and a hard reinforcing layer is arranged on the top face of the mandrel body; the GCR material layer turns up at the periphery. The multifunctional compound fireproof densely-ribbed floor mandrel is convenient to install and excellent in fireproof performance; the fire resistance level can reach the level Aspecified in the item 6.7.3 of GB50016-2014 'Code for Fire Protection Design of Building'. The material which reaches the standard of GB/T20285-2006 is selected, wherein the smoke and poison gas generated during combustion can reach the level ZA1. 本发明公开了种多功能复合防火密肋楼盖芯模，在芯模本体下表面复合有防火岩棉层，在岩棉层下复合有GCR材料层，芯模本体为阻燃EPS材料体，芯模本体顶面设有硬质加强层；所述GCR材料层在四周成向上翻边的形式。本发明安装方便，防火性能优异；耐燃等级可达到A级（《建筑设计防火规范》GB50016-2014之6.7.3条）。选用燃烧时产生的烟雾毒气检测达ZA1级
