一般设计要求厚度为经耐火试验达到耐火极限厚度的1.2倍,以耐火极限为梁2H,柱3H,其设计厚度为梁30MM,柱35MM。


General design requirements for the thickness of the fire resistance test to reach the limit of 1.2 times the thickness of the fire resistance limit for the beam 2H, column 3H, the design of the thickness of beam 30MM, column 35MM.


第一层厚1CM左右,晾干七~八成再喷第二层,第二层厚1~1.2CM左右为宜,晾干七~八成再喷第三层,第三层达到所需厚度为止。


The first layer of thick 1CM or so, dry seven ~ 80% and then spray the second layer, second layer thickness of 1 ~ 1.2CM is appropriate, dry seven ~ 80% and then spray the third layer, the third layer to reach the required thickness.


喷涂时喷枪要垂直于被喷钢构件,距离6~10CM为宜,ystx11a5喷涂气压应保持0.4~0.6MPA,喷完后进行自检,厚度不够的部分再补喷一次。


Spray spray gun to be perpendicular to the sprayed steel component, from 6 to 10CM is appropriate, ystx11a5 spraying pressure should be maintained at 0.4 ~ 0.6MPA, after spraying the self test, the thickness is not enough to spray once again.


正式喷涂前,应试喷一建筑层(段),经消防部门、质监站核验合格后,再大面积作业。施工环境温度低于+5℃时不得施工,应采取外围封闭,加温措施,施工前后48H保持+5℃以上为宜。注册食品公司
