Automatic anchor device and steel strand prestressed tensioning system

Abstract

The invention discloses an automatic anchor device and a steel strand prestressed tensioning system. The automatic anchor device comprises a protecting plate assembly, a tool anchor assembly, an anchor removal plate assembly and a plurality of anchor assemblies. One end of the tool anchor assembly is connected with the protecting plate assembly, and the other end of the tool anchor assembly is movably connected with the anchor removal plate assembly. The protecting plate assembly, the tool anchor assembly and the anchor removal plate assembly are provided with a plurality of protecting plate holes, tapered anchor holes and anchor removal holes correspondingly. Each anchor assembly comprises a spring, a tool clamping piece and an anchor removal sleeve. The steel strand prestressed tensioning system comprises the automatic anchor device, a center hole jack and a pressing sleeve, wherein the center hole jack and the pressing sleeve are matched with the automatic anchor device. The tapered anchor holes are formed in the tool anchor assembly, the tool clamping pieces matched with the tapered anchor holes are arranged, the springs are used for driving the tool clamping pieces to clamp steel strands, the anchor removal sleeves can be used for squeezing the tool clamping pieces clamped in the tapered anchor holes out of the tapered anchor holes, and therefore the automatic anchor device can be automatically anchored on the steel strands and can be removed from the steel strands.

Description

technical field [0001] The invention relates to tension stretching technology, in particular to an automatic anchoring device and a steel strand prestressed tensioning system. Background technique [0002] Tool anchor, a tool-type anchoring device in prestressed tensioning, is a tool that can be used repeatedly in the process of prestressed tensioning. It can be used in conjunction with tool clips to achieve anchoring purposes. The traditional tool anchor and the tool clip are separated before installation. When prestressed tension is required, the overall installation is carried out. During the tensioning process, the tool clip on the tool anchor clamps the steel hinge wire for tension After reaching the design stress and elongation value, the tensioning jack resets, and the tool clip and working anchor are automatically anchored to complete the tensioning process. In actual application, both the tool anchor and the tool clip need to be installed manually. On the one hand,...
