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

Abstract

The invention provides a positioning device capable of performing grouting connection of reinforcing steel bars and metal corrugated pipes in a batch manner. The positioning device comprises a corrugated-pipe positioning system and a reinforcing-steel-bar positioning system and is characterized in that the corrugated-pipe positioning system comprises a corrugated-pipe positioning seat, a pipe-bodypositioning plate and a plurality of screws; the corrugated-pipe positioning seat is provided with a plurality of 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 position of the pipe-body positioning plate can be locked by fasteners at the screws; when corrugated-pipe positioning is performed, the pipe-body positioning plate is located at the screws and the distance between the pipe-body positioning plate and the upper end face of a pipe-orifice positioning seat is smaller than the length of corrugated pipes; the reinforcing-steel-bar positioning system comprises more than one reinforcing-steel-bar positioning plate, the screws penetrate the reinforcing-steel-bar positioning plates, and each reinforcing-steel-bar positioning plate is provided with reinforcing-steel-bar positioning holes corresponding to the pipe-body positioning holes; the distance between thelowermost reinforcing-steel-bar positioning plate and the pipe-body positioning plate is larger than the length of the corrugated pipes. The positioning device is suitable for lab operation, convenient in 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,...

AI Technical Summary

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
