| description | The invention relates to a prestressed reinforcement tensioning construction method suitable for a limited space. The prestressed reinforcement tensioning construction method comprises the following steps that a working anchorage device is installed; mounting a working clamping piece; mounting a professional limiting plate; mounting a common limiting plate; installing a jack; installing a tool anchorage device; installing a tool clamping piece; performing tensioning operation; and sealing the anchor. According to the method, high-quality tensioning can be achieved for the prestressed reinforcement in the limited space, small-space prestressed tensioning construction of the tensioning notch of the cast-in-place box girder can be conveniently achieved by utilizing the professional limiting plate and cooperating with an exclusive tensioning technology, the construction efficiency is improved, the limited space operation time is shortened, meanwhile, the professional limiting plate can be repeatedly used after te |
