Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a prestressed anchor cable sealing device. Background Technology

[0002] In building construction, it is often necessary to seal the anchor heads of anchor bolts, such as in slope construction or structural beam anchor sealing. Currently, the common method is to use wooden formwork to surround the anchor heads on-site, and then pour concrete into the formwork to seal the anchors. However, this method requires on-site fabrication each time (e.g., Figure 6 As shown in the figure, it wastes manpower and material resources, has low construction efficiency, and poor economic benefits. Utility Model Content

[0003] The purpose of this invention is to provide a prestressed anchor cable sealing device that utilizes an integrated shell to achieve anchor sealing construction of the anchor head, is reusable, avoids repeated on-site fabrication and construction, and improves construction efficiency.

[0004] This utility model is achieved through the following measures:

[0005] A prestressed anchor cable sealing device includes a housing disposed at the end of the anchor cable, characterized in that the housing is fixed to the steel pad of the anchor cable by a connecting assembly;

[0006] The steel pad has four threaded mounting holes at the four corners of its front side.

[0007] The connecting assembly includes a connecting screw disposed in the threaded mounting hole, and a mounting sleeve corresponding to the position of the threaded mounting hole is disposed on the housing. A mounting nut is disposed at the end of the connecting screw passing through the mounting sleeve, and the mounting nut abuts against the mounting sleeve.

[0008] The top of the shell is provided with a reserved opening, and the side of the shell opposite to the building structure forms an installation opening.

[0009] The specific features of this utility model also include:

[0010] Several stirrups are provided around the mounting screws in the four threaded mounting holes.

[0011] The end face of the housing is provided with a U-shaped sealing plate.

[0012] The shell is frustoconical in shape.

[0013] After the anchor cable installation is completed, the connecting bolts are installed in the threaded mounting holes at the four corners of the steel pad. Then, stirrups are tied around the connecting bolts. The shell is kept with the reserved opening facing upwards. The connecting bolts are passed through the corresponding mounting sleeves. The U-shaped sealing plate is placed against the building structure. The mounting nuts are installed to limit the installation of the shell. After the shell is installed in place, concrete is poured into the shell through the reserved opening (ensuring that the anchor head is completely embedded in the concrete). After the concrete has formed, the mounting nuts and the shell (the inside of the shell is pre-applied with release agent) are removed. Finally, the exposed end of the connecting bolt is cut to complete the anchor sealing.

[0014] The beneficial effects of this utility model are: the use of an integrated shell to achieve anchor sealing construction of the anchor head is reusable, avoiding repeated construction on site and improving construction efficiency. Attached Figure Description

[0022] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0023] See Figure 1-5 A prestressed anchor cable sealing device includes a housing 1 disposed at the end of the anchor cable, the housing 1 being fixed to the steel pad 4 of the anchor cable by a connecting assembly;

[0024] The steel pad 4 has four threaded mounting holes at the four corners of its front side.

[0025] The connecting assembly includes a connecting screw 5 disposed in a threaded mounting hole, a mounting sleeve 3 disposed on the housing 1 corresponding to the position of the threaded mounting hole, and a mounting nut 6 disposed at the end of the connecting screw 5 passing through the mounting sleeve 3, the mounting nut 6 abutting against the mounting sleeve 3;

[0026] A reserved opening is provided at the top of the shell 1, and an installation opening is formed on the side of the shell 1 opposite to the building structure 7.

[0027] Several stirrups are provided around the mounting screws in the four threaded mounting holes.

[0028] A U-shaped sealing plate 2 is provided on the end face of the housing 1.

[0029] The shell 1 is truncated cone-shaped.

[0030] After the anchor cable construction is completed, install the connecting bolts 5 into the threaded mounting holes at the four corners of the steel pad 4. Then, tie the stirrups around the connecting bolts 5. Keep the shell 1 with the reserved opening facing upwards, pass the connecting bolts 5 through the corresponding mounting sleeves 3, and after the U-shaped sealing plate 2 is pressed against the building structure 7, install the mounting nuts 6 to limit the installation of the shell 1. After the shell 1 is installed in place, pour concrete into the shell 1 through the reserved opening (to ensure that the anchor head is completely embedded in the concrete). After the concrete has formed, remove the mounting nuts 6 and the shell 1 (the inside of the shell 1 is pre-applied with release agent). Finally, cut the exposed end of the connecting bolts 5 to complete the anchor sealing.

[0031] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
