Existing structure reinforcing steel beam anchoring end plate reverse installation trepanning positioning device and construction method

Abstract

The invention relates to an existing structure reinforcing steel beam anchoring end plate reverse installation trepanning positioning device and a construction method thereof. The positioning device comprises a pair of sliding rails which are oppositely arranged; the movable adjusting rod is arranged between the pair of sliding rails in a supporting mode and arranged on the pair of sliding rails in a sliding mode, the movable adjusting rod can be movably adjusted along the sliding rails and can be fastened to the sliding rails after the position is adjusted, and a sliding groove is formed in the movable adjusting rod; the adjusting plate is arranged on the sliding groove in a sliding mode and arranged on the movable adjusting rod, the adjusting plate can be movably adjusted along the sliding groove and can be fastened to the movable adjusting rod after the position is adjusted, and a positioning hole is formed in the adjusting plate. The position of a screw hole actually formed in the existing structure can be positioned by utilizing the positioning hole in the adjusting plate, and then the anchoring end plate is perforated according to the positioning position of the positioning hole, so that the hole in the anchoring end plate can accurately correspond to the hole in the existing structure, and the screw can be mounted.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a positioning device and a construction method for an existing structural reinforced steel beam anchorage end plate reverse-installed opening hole. Background technique [0002] The existing structure reinforced steel beam anchorage end plate is reverse installed, which is different from the traditional steel beam installation process. It is to drill holes in the existing structure, use the connecting screw to fix the existing structure and the anchor end plate, and then fix the steel beam Reverse assembly process with anchor end plate. [0003] The realization of the process of fixing the existing structure and the anchoring end plate with the connecting screw has the following problems: the connecting screw must pass through the screw hole of the existing structure and the screw hole of the anchoring end plate at the same time, and the screw hole of the existing s...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the defects of the prior art, to provide a positioning device and construction method for the reverse installation and opening of the anchoring end plate of the reinforced steel beam of the existing structure, and to solve the problem that the screw hole of the existing structure needs to avoid the setting of the structural steel bar The screw hole on the anchor end plate cannot correspond to it, which leads to the problem that the screw cannot be installed normally
