Description

Technical Field

[0001] The utility model relates to the technical field of ground bolts, in particular to a ground bolt flange pad. Background Art

[0002] In order to ensure the normal use of the ground bolt, it is usually necessary to set a flange gasket at the connection between the bolt body and the valve body of the ground bolt to ensure its sealing and prevent water seepage. Figure 1 As shown in FIG. 1 , it is a schematic diagram of the structure of a ground bolt flange pad in the prior art. The flange pad 1 is provided with a plurality of connection holes 16 through which bolts can pass. Figure 2 As shown, when the bolt body 2 is connected to the valve body 3, the flange gasket 1 is padded between the lower end face of the bolt body 2 and the upper end face of the valve body 3. Under the action of the bolt tensioning force, the flange gasket 1 is compressed and deformed and is in close contact with the bolt body 2 and the valve body 3 to achieve a sealing effect. However, in actual use, it is found that part of the compressed and deformed flange gasket will be squeezed out from between the lower end face of the bolt body and the upper end face of the valve body, and protrude from the outer surface of the ground bolt. This will cause a certain impact on the overall appearance of the ground bolt after installation, and the connecting hole of the flange gasket is not easy to align during the installation process. The installation is relatively difficult, which will cause certain troubles to the normal installation of the installers, and thus needs further improvement. Utility Model Content
