接缝和接缝的密封必须进行慎重的设计,以保证建筑物在最低程度的维护要求下可以有持久的大气密闭性能。对于高层建筑或对环境维护要求很高的建筑物,需要对接缝进行特殊处理,例如采用双层作法的设计。接缝的表面处理,打底层密封混合料以及衬里材料都需经过挑选,以保证材料和工艺的高质量。 Seams and seam seals must be carefully designed to ensure that the building has a durable airtight seal with minimal maintenance requirements. For high-rise buildings or buildings that require high environmental maintenance, joints need to be specially treated, for example with a double-layer design. The surface treatment of the joints, the underlying sealant mix and the lining material have to be selected to ensure the high quality of the materials and processes.
