点驳式玻璃幕墙玻璃板面所受的各种荷载通过驳接爪传给支承结构，玻璃孔和驳接头处有较大的应力集中，所以宜采用钢化玻璃。钢化玻璃用水平钢化能消除玻璃钢化中产生的内应力，减少钢化玻璃上墙后“自爆”的危险。　　钢化玻璃厚度一般选择8毫米、12毫米、15毫米，特殊情况另外 Point-load glass curtain wall glass surface subjected to a variety of loads through the docking claw pass to the supporting structure, glass holes and joints have a greater stress concentration, it should adopt tempered glass. The horizontal toughening of toughened glass can eliminate the internal stress generated in the toughening of toughened glass and reduce the risk of “self-explosion” on the toughened glass wall. Tempered glass thickness of the general choice of 8 mm, 12 mm, 15 mm, special circumstances otherwise
