Abstract

The invention discloses a prestressed anchor for highway bridge construction. and a second sleeve, the right side of the first sleeve is provided with a corrugated pipe, the right end of the first sleeve is fixedly connected with the left end of the corrugated pipe, and the left side of the first sleeve is provided with a baffle , the left end of the first sleeve is fixedly connected with the right side of the baffle, the left side of the baffle is provided with a plug block, the left side of the baffle is fixed with the right end of the plug block, the plug The left side of the block is provided with a second sleeve, and the left end of the plug block is fixedly connected with the right end of the second sleeve. The prestressed anchorage for highway bridge construction can effectively ensure the locking force through multi-stage locking, so as to reduce the failure rate, thereby effectively prolonging the service life of the whole mechanism, significantly improving the practicability, and the use method is simple. Easy to promote.

Description

technical field [0001] The invention relates to the technical field of prestressed anchors for highway bridge construction, in particular to a prestressed anchor for highway bridge construction. Background technique [0002] The prestressed anchorage is suitable for the anchorage used for concrete prestressed tension in the process of engineering construction. Generally used in bridge construction, pre-installed and positioned, and then poured concrete, buried at both ends of the concrete, that is, the two ends of the bellows, which are the end faces set for the stability of the jack during tensioning. Existing prestressed anchorages for highway and bridge construction often use single-stage locking, which leads to high limitations and general practicability. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a prestressed anchor for highway bridge construction, in order to solve the problem that the existing prestressed anchor for highwa...
