Anchorage device clamping piece auxiliary construction device of prestressed beam and construction method of anchorage device clamping piece auxiliary construction device
According to the anchorage device clamping piece auxiliary construction device of the prestressed beam and the construction method of the anchorage device clamping piece auxiliary construction device, a plurality of extrusion rings are adopted for synchronously and radially extruding wedge-shaped clamping blocks to lock a plurality of anchorage device clamping pieces, so that the anchorage device clamping pieces are synchronously installed, manpower is saved, the uniformity of piece positions can be guaranteed, and the construction efficiency is improved. The installation efficiency of the anchorage device clamping pieces is improved, the rework rate is reduced, a guarantee is provided for follow-up construction, meanwhile, a plurality of anchorage device clamping pieces can be conveniently fixed and arranged on a prestressed cable (namely a steel strand) in a sleeving mode, when the clamping pieces are fixed through the clamping and fixing device, the end face of the pushing sleeve abuts against the end faces of the anchorage device clamping pieces, and therefore the anchorage device clamping pieces can be fixed conveniently. When the anchorage device clamping pieces are tightened, buffering and damping are conducted on hammering of constructors, all the clamping pieces are evenly stressed, and the phenomenon that the constructors exert too much force and break the clamping pieces is avoided. The problems that an existing clamping piece type anchorage device of the prestressed beam is low in working clamping piece installation efficiency and unstable in installation quality are solved.
本发明公开了一种预应力梁的锚具夹片辅助施工装置及其施工方法，采用多个挤压环同步径向挤压楔形夹块以锁定多个锚具夹片，使得多个锚具夹片同步安装，不仅节省人力，而且能保证片位的均匀，提高锚具夹片的安装效率并减少返工率，为后续施工提供了保障，同时，方便对多个锚具夹片进行固定并套在预应力索(即钢绞线)上，在夹固装置固定夹片时，将顶推套管的端面抵顶于锚具夹片的端面，在锚具夹片进行打紧时为施工人员的锤击进行缓冲和减震，并使每片夹片均匀受力，防止施工人员用力过猛，将夹片敲坏。本发明解决了现有的预应力梁的夹片式锚具的工作夹片安装效率低且安装质量不稳定的问题。
