Technical Field

[0001] This utility model belongs to the field of anchor head sleeve sealing technology, and in particular relates to an anchor head sleeve sealing device after prestressed tendon tensioning. Background Technology

[0002] Concrete is a common building material in the construction industry today. Prestressed tendons are added to the concrete to enhance the strength of the concrete structure. Anchor sleeves are used to tension the prestressed tendons to ensure their function. To ensure the stability of the anchor sleeves, they are sealed with concrete to prevent them from contacting the outside environment.

[0003] During the process of sealing the anchor head sleeve, the groove on the end face of the concrete structure must be covered by a panel to prevent concrete from flowing out. However, due to the lack of adhering materials on the concrete surface, the panel is prone to falling off, which affects the covering effect and thus has a certain impact on the sealing effect. In order to solve the above problems, there is an urgent need for a prestressed tendon tensioning anchor head sleeve sealing device. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the process of sealing anchor head sleeves, it is necessary to use a panel or the like to cover the groove on the end face of the concrete structure to prevent concrete from flowing out. However, due to the lack of adhering materials on the concrete surface, the panel is easy to fall off, which affects the covering effect and thus has a certain impact on the sealing effect. Therefore, a prestressed tendon tensioning anchor head sleeve sealing device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a prestressed tendon tensioning anchor head sleeve sealing device, including a panel, a grouting hole is provided in the panel, a connecting component is provided on one side of the panel, and a fixing component is provided on one side of the panel;

[0006] The connecting assembly includes a mounting cylinder, one end of which is fixedly connected to a connecting rod, and the other end of which is fixedly connected to a vibrator. A push plate is slidably connected to the mounting cylinder through a groove inside it. A bolt is threadedly connected to the push plate through a threaded hole inside it. A spring is fixedly connected to the inner wall of the mounting cylinder, and a clamping plate is fixedly connected to the bottom end of the spring.

[0007] As a further description of the above technical solution:

[0008] The mounting cylinder is slidably connected to the panel through a through hole, and the bolt is rotatably connected to the mounting cylinder through a through hole at one end.

[0009] As a further description of the above technical solution:

[0010] One end of the push plate is in contact with the clamping plate and the contact surface is inclined, and the spring is located in the groove opened on the surface of the clamping plate.

[0011] As a further description of the above technical solution:

[0012] The push plate and clamping plate are each arranged in two sets symmetrically, and one end of the mounting cylinder is provided with an opening.

[0013] As a further description of the above technical solution:

[0014] The fixing component includes a mounting plate, one side of which is fixedly connected to the panel.

[0015] As a further description of the above technical solution:

[0016] One end of the mounting plate is fixedly connected to a fixing frame, and a sealing gasket is provided on one side of the fixing frame.

[0017] As a further description of the above technical solution:

[0018] The mounting plate is threadedly connected to a threaded rod through a threaded hole therein, and a fixing plate is fixedly connected to one end of the threaded rod.

[0019] As a further description of the above technical solution:

[0020] One end of the fixing plate is fixedly connected to the outer wall of the mounting cylinder, and the threaded rod is threadedly connected to it through a threaded hole opened in the panel.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] 1. In this utility model, by providing a clamping plate inside, the installation cylinder is sleeved on the outside of the anchor head of the prestressed tendon during use. The rotating bolt drives the push plate to move and push the clamping plate to squeeze the anchor head inside the installation cylinder. Concrete is then poured into the groove on the end face of the concrete structure through the grouting hole. At the same time, a vibrator can be activated to vibrate during the grouting process. This design enables the installation cylinder to be connected to the anchor head through the clamping plate when sealing the anchor head sleeve, thus preventing the device from falling off during the grouting process and affecting the sealing effect. At the same time, the vibrator allows the concrete to fully contact the anchor head sleeve during grouting, thereby improving the sealing effect.

[0023] 2. In this utility model, by providing a sealing gasket inside, after connecting the mounting cylinder to the anchor head, the panel and mounting plate can be moved by rotating the threaded rod, and the fixing frame can be moved as well. This allows the fixing frame to contact the end face of the concrete structure, and the sealing gasket can fill the gap between the fixing frame and the end face of the concrete. Through this design, the gap between the panel and the end face of the concrete structure can be filled by the sealing gasket during use, thereby preventing concrete from leaking out of the gap when filling the groove of the end face of the concrete structure, thus ensuring the smooth sealing.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-4 This utility model provides a technical solution: a prestressed tendon tensioning anchor head sleeve sealing device, including a panel 1, a grouting hole 2 is provided in the panel 1, a connecting component 4 is provided on one side of the panel 1, and a fixing component 3 is provided on one side of the panel 1.

[0032] The connecting assembly 4 includes a mounting cylinder 43, one end of which is fixedly connected to a connecting rod 42, and the other end of which is fixedly connected to a vibrator 41. A push plate 45 is slidably connected to the mounting cylinder 43 through a groove therein, and a bolt 44 is threadedly connected to the push plate 45 through a threaded hole therein. A spring 46 is fixedly connected to the inner wall of the mounting cylinder 43, and a clamping plate 47 is fixedly connected to the bottom end of the spring 46.

[0033] The mounting cylinder 43 is slidably connected to the panel 1 through a through hole. The bolt 44 is rotatably connected to the mounting cylinder 43 through a through hole at one end. One end of the push plate 45 is in contact with the clamping plate 47 and the contact surface is inclined. The spring 46 is located in the groove on the surface of the clamping plate 47. The push plate 45 and the clamping plate 47 are symmetrically arranged in two sets. One end of the mounting cylinder 43 is provided with an opening.

[0034] The specific implementation method is as follows: When in use, the installation cylinder 43 is sleeved on the outside of the anchor head of the prestressed tendon, and the push plate 45 is moved by rotating the bolt 44. The inclined surface at one end of the push plate 45 pushes the clamping plate 47 to move and stretches the spring 46. The movement of the clamping plate 47 squeezes the anchor head inside the installation cylinder 43, so that the installation cylinder 43 is connected to the anchor head. Then, the panel 1 is brought into contact with the end face of the concrete structure by the fixing component 3. Concrete can be injected into the groove of the end face of the concrete structure through the grouting hole 2 and prevented from flowing out by the panel 1. At the same time, the vibrator 41 can be activated to vibrate during the injection process, so that the concrete can be fully filled into the groove of the end face of the concrete structure.

[0035] The fixing component 3 includes a mounting plate 33, one side of which is fixedly connected to the panel 1. A fixing frame 31 is fixedly connected to one end of the mounting plate 33. A sealing gasket 32 ​​is provided on one side of the fixing frame 31. A threaded rod 34 is threadedly connected to the mounting plate 33 through a threaded hole. A fixing plate 35 is fixedly connected to one end of the threaded rod 34. One end of the fixing plate 35 is fixedly connected to the outer wall of the mounting cylinder 43. The threaded rod 34 is threadedly connected to the mounting plate 1 through a threaded hole.

[0036] The specific implementation method is as follows: After the mounting cylinder 43 is connected to the anchor head, the panel 1 and the mounting plate 33 can be moved by rotating the threaded rod 34, and the fixing frame 31 can be moved, so that the fixing frame 31 can contact the end face of the concrete structure. The panel 1 can cover the groove of the concrete end face, and the sealing gasket 32 ​​can fill the gap between the fixing frame 31 and the concrete end face.

[0037] Working principle: During use, the installation cylinder 43 is fitted onto the outside of the anchor head of the prestressed tendon. The rotating bolt 44 drives the push plate 45 to move, which in turn pushes the clamping plate 47 to move and stretches the spring 46 through the inclined surface of one end of the push plate 45. The movement of the clamping plate 47 compresses the anchor head inside the installation cylinder 43, connecting the installation cylinder 43 to the anchor head. Then, the rotating threaded rod 34 drives the panel 1 and the installation plate 33 to move, and drives the fixing frame 31 to move, so that the fixing frame 31 can contact the end face of the concrete structure. The panel 1 covers the groove of the concrete end face, and the sealing gasket 32 ​​fills the gap between the fixing frame 31 and the concrete end face. Concrete can then be injected into the groove of the concrete end face through the grouting hole 2, and the panel 1 prevents it from flowing out. During the injection process, the vibrator 41 can be activated to vibrate, so that the concrete can fully fill the groove of the concrete end face.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
