四川省电力局某发电厂在车间办公楼的室内外照明线路工程中,利用当地廉价出售的木槽板(每米3～5分钱),代替钢管作暗配(图1)。使用证明这种暗配的质量是好的,满足了设计和使用要求,而成本与明配差不多。此法也可以用于普通民用建筑。具体做法是;将线路根据明配设计好走向,按暗配设计好预埋件后,所有预埋件在与砌体工程交叉施工中均埋在砌体之中。砌体工程结束建筑物尚未装修之前即将线路全部安装完毕(开关,插座、灯具暂不装),并测试通电。经确定所有线路连接无误之后,再进行粉刷和装修,并将全部线路埋在抹灰层里(图2)。待全部土建装修完成之后,再安装开关、插座和灯具等电器。
A power plant of the Sichuan Provincial Electric Power Bureau used indoor low-cost wooden trough boards (3 to 5 cents per meter) in the indoor and outdoor lighting circuits of the office building of the workshop to replace the steel pipe for concealed distribution (Figure 1). The use proves that the quality of this implied fit is good, meets the design and usage requirements, and costs about the same as the open mix. This method can also be used for ordinary civil buildings. The specific approach is to design the line according to the design of the Ming Li, and after designing the embedded parts according to the concealment, all the embedded parts are buried in the masonry during the cross construction with the masonry project. The end of the masonry project will be completed before the building has been renovated (switches, sockets, lamps temporarily installed), and test power. After confirming that all the lines are connected correctly, they are painted and renovated, and all lines are buried in the plaster layer (Fig. 2). After all the civil works are completed, install electrical appliances such as switches, sockets and lamps.
