众所周知,普通多孔板以其平整、经济和效果稳定被建筑界广泛用于屋面铺设,曾经占居半壁江山。但由于物体热胀冷缩的性质常在板与板交界处此薄弱环节产生裂缝而漏水,本设计完全能改变此种局面,它与普通多孔板完全一致,可与普通板间隔使用,经处理后的板边能诱导裂缝在导流型板边产
As we all know, ordinary perforated plate with its flat, economical and stable effect is widely used by the construction industry roofing, once accounted for half of the country. However, due to the nature of thermal expansion and contraction of objects at the junction of plate and board cracks and leakage at this weak link, this design can completely change this situation, it is exactly the same with the ordinary porous plate can be used with the ordinary plate interval, the treated After the board edge can induce cracks in the diversion board edge production
