市建三○六队从去年下半年开始,在15幢工房建造中,改变传统的随结构施工脚手架逐排逐层向上搭设的作法,在结构施工阶段用附墙式安全网,仅在装饰施工阶段搭脚手架,取得较好的效果。附墙立式安全网每榀重约130公斤,由脚手管、机件、安全网组合而成。墙体砌筑到800毫米高度(二皮砖块)时,在长墙上利用砌块或砖墙灰浆缝每隔2750毫米(二山墙每隔2000～2300毫米)留置20×100毫米孔洞。在底层结构完成后安装底座,如遇窗盘,可用铁销扎进下一皮灰缝中,底座用10~#铅丝固定于铁销上。安装网架时,将竖杆插入底座,在楼板面处用10~#铅丝把网架横楞与预制板吊钩相连,使竖杆距墙150毫米左右,长
The city’s construction of the “306” team began in the second half of last year, during the construction of 15 workshops, and changed the traditional method of erecting buildings one by one with the construction scaffolding, using a wall-type safety net during the construction phase of the construction. Scaffolding stage to achieve better results. The vertical wall-mounted safety net weighs about 130 kilograms each, and is made up of a combination of scaffolding, parts and safety nets. When the wall is masonry to a height of 800 mm (two-brick), a 20×100 mm hole is reserved on a long wall using block or brick-and-mortar mortar every 2750 mm (every 2000-2,300 mm in two gables). After the bottom structure is completed, the base is installed. In case of a window pane, iron pins can be used to tie into the next mortar seam. The base is fixed on the iron pins with 10~# lead wires. When installing the grid, insert the vertical bar into the base, and use the 10~# lead wire at the floor surface to connect the horizontal bar of the grid to the hook of the prefabricated plate so that the vertical bar is about 150 mm from the wall.
