Masonry

Masonry Cavity Walls and Moisture Control

Description

Masonry cavity walls use two wythes, or layers, with a hollow space between them. The outer and inner wythes are linked only by corrosion-resistant metal ties. This design helps manage water and improve wall performance.

When rainwater passes through the outer wythe, it moves down through the cav...

空心砌体墙由两个叶墙组成,中间隔有空腔。外叶墙和内叶墙通过耐腐蚀的砌体拉结件连接,以确保结构稳定性。

当水渗入外墙外叶时,会进入空腔,并由安装在空腔底部的一种称为泛水的薄型不透水膜收集,随后通过泄水孔排出。

此外,在内层砌体墙的空腔侧施加防潮材料,可防止水渗入室内,同时还能起到空气阻隔的作用。

施工过程中,灰浆滴落等杂物可能堵塞排水系统,因此保持空腔畅通至关重要。使用灰浆挡板材料有助于避免空腔内排水系统堵塞。

该空腔有助于隔音,并便于在建筑内部布置用于公用设施分配的管道。

此外,在空腔中插入刚性泡沫塑料隔热板可提供保温效果。

空心墙可以是承重墙或非承重墙。在承重空心墙中,内叶墙承担结构荷载,而外叶墙为非...
