本发明涉及锚具技术领域，具体为一种预应力多孔锚具，包括锚具体，所述锚具体上均匀开设有三个用于通过预应力筋的锚孔，还包括夹片安装器，所述锚具体上设置有用于安装锚具夹片的夹片安装器。本发明通过夹片安装器辅助锚具夹片的安装，当安装锚具夹片时，通过夹片安装器，安装所有靠近锚具体外侧壁处的锚具夹片以及所有靠近锚具体中心一侧的锚具夹片，再通过夹片安装器内部的配合关系，使靠近锚具体外侧壁处的锚具夹片与靠近锚具体中心一侧的锚具夹片相互配合并共同夹住预应力筋，使所有锚具夹片被同时安装到锚具上，节省安装锚具夹片的时间，提高施工效率。

The invention relates to the technical field of anchorage devices, in particular to a prestressed multi-hole anchorage device which comprises an anchorage device body and a clamping piece installer, three anchor holes for prestressed tendons to pass through are evenly formed in the anchorage device body, and the clamping piece installer for installing anchorage device clamping pieces is arranged on the anchorage device body. The clamping piece installer assists in installation of the anchorage device clamping pieces, when the anchorage device clamping pieces are installed, all the anchorage device clamping pieces close to the outer side wall of the anchorage device body and all the anchorage device clamping pieces close to one side of the center of the anchorage device body are installed through the clamping piece installer, and then the anchorage device clamping pieces are installed through the internal matching relation of the clamping piece installer. The anchor device clamping pieces close to the outer side wall of the anchor body and the anchor device clamping pieces close to one side of the center of the anchor body are matched with each other and clamp prestressed tendons together, so that all the anchor device clamping pieces are installed on the anchor device at the same time, the time for installing the anchor device clamping pieces is saved, and the construction efficiency is improved.
