楼地面和抹灰面的空鼓问题,至今还是创优工程的“拦路虎”。本文以常规施工中,容易发生空鼓的建筑材料和工程部位,针对它的特殊性,“对症下药”。一、面层容易空鼓的建筑材料1.大尺寸板块不易垫实。花岗石和预制水磨石块楼地面,通常采用硬底子、软座浆方法铺贴,即地面垫层或楼板砼硬化之后,虚铺“软”砂浆厚约20mm,铺贴板块。它有两个缺点:①砂浆用灰匙摊
The hollowing out of floor and plastering surfaces is still a “stopping road” for excellence projects. In this paper, in routine construction, hollow construction materials and engineering parts are prone to occur, and for its particularity, “prescription for the disease.” 1. Construction materials that are easy to empty in the surface layer 1. The large-sized plates are not easy to cushion. Granite and prefabricated terrazzo blocks are usually floored with a hard-base or soft-seat method. After the floor mat or floor slab is hardened, the virtual shop “soft” mortar has a thickness of about 20 mm and is tiled. It has two disadvantages: 1 mortar with ash spoon
