Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of anchor sealing, specifically to a prestressed anchor head anchor sealing tool. BACKGROUND

[0002] Prestressed member anchor sealing refers to the process of sealing the prestressed tendon and its anchor device that have completed tensioning in the prestressed concrete structure. The main purpose of anchor sealing is to prevent the anchor device and prestressed tendon from being corroded or mechanically damaged by the external environment, and to ensure the long-term stability and durability of the structure.

[0003] A prefabricated beam yard anchor sealing device is disclosed in the Chinese patent application publication (CN220614448U), which relates to the technical field of prefabricated beams and includes a filling bucket, a vibration unit that penetrates the top plate of the filling bucket, and a limiting unit. The vibration unit includes a T-shaped rod that penetrates the top plate of the filling bucket, a mounting cylinder that is fixedly connected to the end face of the T-shaped rod and located inside the filling bucket, and a vibration motor that is fixedly connected inside the mounting cylinder and used to drive the mounting cylinder to vibrate. The limiting unit includes a limiting rod that is fixedly connected to the top of the mounting cylinder and has an end face extending to the outer surface of the filling bucket, a liquid storage chamber that is opened in the top of the limiting rod, and a discharge hole that penetrates the inner bottom wall of the liquid storage chamber.

[0004] This technical solution provides a prefabricated beam yard anchor sealing device. The limiting rod is set to allow the mounting cylinder to only move reciprocally along the axial direction of the filling bucket, thereby avoiding the rotation of the mounting plate inside the filling bucket. The lubricating oil inside the liquid storage chamber is delivered to the outer sidewall of the limiting rod, which reduces the wear of the limiting rod. In this technical solution, the T-shaped rod is used to push the mounting plate outward, which can push the concrete in the filling cylinder out. However, in existing construction standards, the anchor sealing concrete usually uses a cement paste with a strength grade not lower than 40MPa. The initial setting time of this strength grade of cement paste is 3 to 6 hours. Demolding before initial setting can easily cause the collapse of concrete and affect the strength. To avoid misoperation by workers, an anchor sealing tool that restricts demolding should be provided. CONTENT OF THE UTILITY MODEL
