THF复合难燃桥架:

THF型复合难燃桥架产品是以无机不燃材料为基体，在其表面复合有机高分子难燃材料制成，综合有机系列与无机系列的优点，具有氧指数高，难燃耐腐蚀、强度高、耐候性好，施工方便等特点。适用于电力、石化、冶金、邮电通讯、建筑等行业各种等级的电缆防火保护和耐火分隔。特别适合含盐雾化学气体、严寒、酷热等各种环境条件使用。是一种有重要回路电缆及防火防腐要求的场所中钢制桥架的理想新型替代产品。

THF The Composite Flame Retardant Bridge takes inorganic non-inflaming material as basic body,which is made through compounding organic polymer sparingly-flaming material on the surface,combining with advantages of organic and inorganic series with characters as high oxygen index,sparingly flaming, corrosion tolerance, high strength,  good climate tolerance and convenientconstruction etc. it is suitable for cable fireproofing protection and fire- -tolerance separation of variouslevels in electrify, petrifaction, metallurgy, post and telecommunications, and building etc, especially forvarious environments of chemical gas with salt fog, chilliness and extremely hot etc, so it is a kind of idealnew substitute product of steel crane span structure in sites with requirements of important loop cable,fireproofing and corrosion-proofing.

施工方法：

1.有各种标准规格供用户选用，也可以根据用户要求定制。

2.桥架安装时，用专用挂钩螺栓(配专用垫片或用连接螺栓)与托臂固定;桥架之间接头用普通螺栓(配专用垫片)连接;在桥架始、终端及每隔1000mm间距用专用捆扎带和锁紧扣固定。

3.桥架安装时，如遇到现场实际变更、管道交叉或有电缆弓出等情况，可根据现场实际情况对架桥进行切割、钻孔或拼接。

1.Various standards and regulations are offer to users,which can beformulated according to demands of users.

2.While installing, the crane span structure should be fastened byspecial pothook bolt (associated with special gasket or connecting bolt)and corbel; adapter connectors between crane span structures shouldbe connected through common bolt (associated with special gasket);both sides of the crane span structure and each distance of 1000mmshould be fastened through special strapping tape and locking buttons.

3.While installing, the crane span structure should be cut, drilled ormontage according to practical situation on the scene whenencountering practical alternation, pipeline crossing.
