Clamping system for external prestressing two-end tensioning
The invention discloses a clamping system for external prestressing two-end tensioning. The clamping system comprises a clamping part, a connecting part and a binding part. The clamping part comprises a first clamping piece and a second clamping piece; the first clamping piece and the second clamping piece are respectively clamped on two opposite outer surfaces of the structure and are fastened through a screw rod; the number of the clamping parts is two, and a steel fiber bundle is clamped by the clamping parts. The two ends of the connecting part are fixed to the two opposite ends of the two first clamping pieces correspondingly so that the two first clamping pieces can be connected into the clamping system. The binding part is annularly arranged at the end of the clamping part in a sleeving mode so as to change the tensioning inclination angle of the steel fiber bundle. The binding part can apply a pre-tightening force to the clamping part, so that a steel fiber bundle warps upwards by a certain angle, the tensioning equipment is arranged at one ends of the two connecting parts, and meanwhile, the steel fiber bundle is tensioned, so that external pre-stress can be applied to a structure in a multi-angle and multi-layer composite manner; and it can be ensured that external prestress is applied more perfectly through different force application stages.
本发明公开了一种用于体外预应力两端张拉的夹持系统，包括包括夹持部、连接部和捆绑部；夹持部包括第一夹持件和第二夹持件，第一夹持件和第二夹持件分别夹持在结构物相对的两外表面并通过螺杆紧固；其中，夹持部设有两个且夹持有钢纤维束；连接部的两端分别与两个第一夹持件相对的两端部固定以将其连接成夹持系统；捆绑部呈环装套设在夹持部的端部以改变钢纤维束的张拉倾角。本发明中捆绑部可以给夹持部施加一个预紧力，使得钢纤维束上翘一定的角度，张拉设备设置在两个连接部的一端同时对钢纤维束进行张拉，可以对结构物多角度、多层次的复合加载体外预应力，通过不同的施力阶段可以确保体外预应力的施加更加完善。
