Positioning device capable of performing grouting connection of reinforcing steel bars and metal corrugated pipes in batch manner

Abstract

The present invention proposes a positioning device capable of performing grouting connection between steel bars and metal bellows in batches, including a bellows positioning system and a steel bar positioning system; the bellows positioning system includes a bellows positioning seat, a pipe body positioning plate and a plurality of screws; The bellows positioning seat is provided with several pipe end positioning blind holes, and the pipe body positioning plate is provided with pipe body positioning holes corresponding to the pipe end positioning blind holes; the pipe body positioning plate can be fixed by the fastener at the screw rod. Locking position; when the bellows is positioned, the pipe body positioning plate is locked at the screw, and the distance between the pipe body positioning plate and the upper end surface of the nozzle positioning seat is less than the length of the bellows; the steel bar positioning system includes the screw above the pipe body positioning plate More than one steel bar positioning plate is placed, and each steel bar positioning plate is equipped with a steel bar positioning hole corresponding to the positioning hole of the pipe body; the distance between the steel bar positioning plate on the bottom layer and the pipe body positioning plate is greater than the length of the bellows; this product is suitable for Laboratory operation, convenient construction and reusable.

Description

technical field [0001] The invention relates to the field of construction, in particular to a positioning device that can perform grouting connection of steel bars and metal corrugated pipes in batches. Background technique [0002] This device is invented in the stage of specimen fabrication of the bidirectional quasi-static test research of segmental assembled single-column piers. The general fabrication steps of segmented assembled bridge piers are to splicing the prefabricated pier body segments and the caps, and then splicing the pier body. The main bars reserved for the segment are embedded in the metal bellows pre-buried in the cap, and then high-strength mortar is used to perfuse the bellows and the joint between the pier body and the cap. The steel bars reserved for the pier body should be arranged in the center of the metal bellows At this point, the steel bars and the metal corrugated pipes are evenly stressed, the anchoring capacity of the steel bars is improved,...

Problems solved by technology

For the problem of how to place the steel bar in the center of the metal bellows, if a single mold-making method is used, it will not only take time and effort, but also delay the test process
