在预应力砼结构工程中,张拉和锚固体系是其关键设备。为了克服有顶压锚具不能满足大吨位应用的不足,开封中原预应力工艺设备厂等单位设计研制了一种新型的XYM型后张锚固体系。这种设备的最大特点是具有良好的自跟进,自锚同性能,为实现无顶压张拉锚固奠定了基础。该新型锚垫板在推广应用之前,研制单位委托我们对其 Tensile and anchorage systems are key equipment in prestressed concrete structures. In order to overcome the shortage of top pressure anchorages that can not meet the application of large tonnage, Kaifeng Central Plains prestressed process equipment factory and other units designed and developed a new type of XYM anchoring system. The biggest feature of this kind of equipment is that it has good follow-up, self-anchoring performance, and lays the foundation for the implementation of tension-free tension anchorage. Before the new anchor plate was promoted and applied, the development unit commissioned us to
