地坪施工通常是先打底子,然后铺砂浆,用刮杆刮平。这样做水平误差较大。如用水准刮杆刮平,水平误差较大的问题就解决了,并把两道工序合成为一道工序了。水准刮杆同刮杆外形的尺寸一样,宽80～120毫米,厚8～15毫米,见图1,在水准刮杆的左端上钉一把水平尺。钉时,水准刮杆放到已 Floor construction is usually preceded by a base, then mortared and scraped with a spatula. This has a large horizontal error. If horizontal scraping is used to scrape the rod, the problem of large horizontal error is solved, and the two processes are combined into one process. The levelling scraper is the same as the size of the scraper, 80 to 120 mm wide and 8 to 15 mm thick. See Figure 1. A level bar is nailed to the left end of the leveling bar. When nailing, the leveling bar has been put
