一、问题的提出以往,为进行电站厂房天面批挡施工,一般在浇完厂房天面钢筋混凝土以后,待混凝土达到28天强度时,才能拆除天面模板和支撑排架,再重搭建脚手架,用高标号的纸筋水泥砂浆进行天面批挡和喷扫白灰。这样的施工方法,主要存在以下两个问题:一是工期长,须有近1个月的混凝土养护期才能拆除模板和支撑排架,拆完模板后,还需要10多天的时间搭建批挡用的脚手架,才能进行天面批挡。按以往厂房天面的施工进
First, the problem raised In the past, in order to carry out the power plant plant surface construction approved in batches, usually after pouring finished steel reinforced concrete surface, until the concrete reaches 28 days strength, in order to remove the surface formwork and support the rack, and then re-build scaffolding , With high grade paper mortar cement mortar and sweep the sky fly ash. This construction method, there are two main problems: First, the long construction period, there must be nearly a month of concrete curing period to dismantle the template and support the rack, after dismantling the template, it will take more than 10 days to build a block Use of scaffolding, in order to block the sky. According to the past construction days into the plant floor
