对于设备安装通常是采用予埋钢板、予埋螺钉等施工方法,这些方法施工复杂,劳动量大,材料消耗指标高,施工周期长,并给设计工作增加了较大工作量。不能满足我国基本建设蓬勃发展的需要。膨胀螺栓的优点是埋深浅,施工简便,效率高,可大量节约材料,调整设备速度快。对基本建设和工厂企业中技术改造都很有利。 For equipment installation is usually used to embed steel plate, embedded screws and other construction methods, these methods of complex construction, labor-intensive, high material consumption indicators, the construction period is long, and the design work to increase the workload. Can not meet the needs of vigorous development of our country’s basic construction. The advantages of expansion bolts are shallow depth, simple construction, high efficiency, can save a lot of material, adjust the equipment speed. It is good for technological transformation in capital construction and factory enterprises.
