Special rapid installation type prestress anchorage device

Abstract

The invention discloses a special rapid installation type prestress anchorage device which comprises anchorage device clamping pieces and a fixed anchorage device and further comprises a movable anchorage device and connection bolts; a limiting block is arranged on the side wall of the bottom end of each square hole; an angle regulation plate is arranged on the upper side of the bottom of each square hole; angle regulation shafts are arranged below the angle regulation plates; arc raised blocks which are consistent in height are arranged at the front ends of the angle regulation shafts; the lower ends of the angle regulation plates are in contact with the raised blocks; a round through hole is formed in the center position at the bottom of each square hole; inclined movable plates are arranged on both left and right side walls of each square hole; the top ends of the movable plates are hinged to the movable anchorage device; springs I are arranged between the lower ends of the movableplates and the movable anchorage device; external screw threads are formed at the tail ends of the connection bolts; and the connection bolts are matched with threaded blind holes after passing through through holes. The special rapid installation type prestress anchorage device disclosed by the invention is a special bridge reinforcement prestress anchorage device which can be used for mounting aplurality of anchorage device clamping pieces for one time and is convenient to operate and simple and rapid to mount.

Description

technical field [0001] The invention relates to a fast-installed prestressed special anchorage. Background technique [0002] Anchors refer to the permanent anchoring devices used in prestressed concrete. They are anchoring tools used in post-tensioned structures or components to maintain the tension of the prestressed tendons and transfer them to the interior of the concrete. Generally, it is widely used in road bridges, railway bridges, urban overpasses, urban light rail, high-rise buildings, water conservancy and hydropower dams, port terminals, tunnel mine top anchor tops, subways, large containers and ships, sleepers and other fields. [0003] At this stage, the method of placing the anchor on the steel bar is relatively simple. First, the fixed anchor is set on the steel bar, and then the anchor clips are placed one by one in the gap between the two sides of the steel bar and the through hole of the fixed anchor. In this installation method, the anchor clips are easy ...

[0003] At this stage, the method of placing the anchor on the steel bar is relatively simple. First, the fixed anchor is set on the steel bar, and then the anchor clips are placed one by one in the gap between the two sides of the steel bar and the through hole of the fixed anchor. In this installation method, the anchor clip is easy to fall off during installation, and it needs to be installed repeatedly, and only one anchor clip on the steel bar can be installed at a time, which is time-consuming and laborious

At this stage, there is no suitable anchor installation tool to replace manual installation, and manual installation can only be installed one at a time, which is a waste of time and inefficient
