建筑中只要遇到有自动扶梯的,土建施工时都须按厂家要求预埋一块与扶梯宽度相当的钢板,如图1所示自动扶梯,就需要预埋一块20mm厚的钢板。这种预埋钢板如何施工,有3种方法。方法一对已确定厂家的土建施工图,按设计图上的要求,在扶梯支撑梁上预埋钢板,钢板下的锚筋与梁主筋焊接(图2)。方法二对土建已施工完毕,后加预埋钢板的,可以采用打膨胀螺栓固定钢板的方法,但应注意膨胀螺栓位置需避开扶梯安装螺栓,节点图如图3所示。方法三对来不及装预埋钢板,扶梯
As long as the building encountered an escalator, civil construction must be required by the manufacturer to embed a plate width and escalator, escalator shown in Figure 1, you need to embed a 20mm thick steel. There are 3 ways to construct this kind of embedded steel plate. Method A pair of civil construction drawings have been identified manufacturers, according to the requirements of the design drawings, embed the steel plate on the escalator support beam, the anchor under the steel plate and the main beam welding (Figure 2). Method Two pairs of civil construction has been completed, after the increase of embedded steel, expansion bolts can be used to fix the steel plate method, but should pay attention to the expansion bolt position to avoid the escalator installation bolts, node diagram shown in Figure 3. Method three pairs of embedded steel plate, escalator
