1、防静电地板施工工法四川电力送变电建设公司张成进1.前言在变电站通讯设备和继电器室，为了防止静电对各种保护设备的影响，采用防静电地板作为通讯和继电器室的地坪。通过多个变电站的静电地板施工经验积累形成了变电站防静电地板施工工法。2.工法特点2.1利用防静电地板的架空活动空间进行电缆展放，在有利保护设备运行的环境下，保持通讯和继电器室的美观。2.2采用防静电地板代替原砼地板妥善地解决了静电对各种保护设备和通讯的影响。2.3将轻型防静电地板代替原地板，减小地板自重。3.适用范围变电站（换流站）要求防静电的房间，如
2、：通讯、继电器室、控制室。4.工艺原理采用在地板上安装支座及桁梁，用吸板器在组装好的桁梁上放置活动地板的工艺，满足防静电性能和充分的地板下走线空间。5.施工工艺流程及操作要点5.1施工工艺流程施工准备→拉水平线→弹出安装支座的网络格线→将支座摆到地面网格线的十字交点处→调整安装支座到同一需要的高度→用安装螺钉将桁梁固定到支座上→放置活动地板→调整地板。如图图5.2-1。5.2操作要点5.2.1认真检查地面平整度及墙面垂直度，如发现有需要局部改造，应在静电地板施工前进行；5.2.2拉水平线，并将地板安装高度
