膨胀螺栓是一种新颖的紧固件。我国从七十年代初就开始研制并推广应用,尤其是近几年,更扩大了应用面。从我们多年来在工程上应用的情况来看,以膨胀螺栓作为紧固件,确实具有速度快、质量好和省钢材的优点。下面谈谈我们在应用膨胀螺栓中的一些看法和体会。 Expansion bolts are a novel type of fastener. Since the early 1970s, China began to develop and promote its application, especially in recent years, but also expanded its application. From our years of engineering applications, the expansion bolt as a fastener, does have the speed, good quality and the advantages of steel. Here to talk about our application of expansion bolts in some of the views and experience.
