不发火水磨石楼、地面层,适用于有防爆要求的地面,在地面受物体撞击和摩擦时不发生火花。因为铜条、玻璃条是发火材料,不能用来做不发火水磨石面层分格嵌条。铝条是不发火材料,但铝条容易被水泥腐蚀,刚度差,用做分格嵌条后,贴结不牢,易松动、脱出。厂房大面积不发火水磨石面层施工时,如果不加分格嵌条,难度将会增大。我们在厂房大面积水磨石地面施工中,采用了如下方法:将10毫
The terrazzo floor and ground floor are not ignited, and are suitable for grounds with explosion-proof requirements. Sparks do not occur when the ground is hit and rubbed by objects. Because copper strips and glass strips are pyrophoric materials, they cannot be used to make unburned terrazzo surface layers. Aluminum bars are not pyrophoric materials, but aluminum bars are easily corroded by cement and have poor rigidity. After being used as sub-grid moldings, the affixing is not firm, easy to loosen, and comes out. When a large area of a workshop is not blazing terrazzo facing construction, the difficulty will increase if there is no additional gridding. In the large-scale terrazzo floor construction of our factory, we used the following method:
