JP3010349U - U-shaped belt bolt - Google Patents

Abstract

(57) [Summary] [Purpose] To supply the market with pipe mounting bolts that compensate for the shortcomings of U-shaped bolts and have increased mounting strength. [Structure] A U-shaped band bolt having a shape as shown in Fig. 1 is manufactured by making a surface contact with a mounting surface such as a pipe and tightening the same.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bolt and its shape necessary for attaching and fixing parts to a cylindrical object such as a metal pipe.

[0002]

[Prior art]

 Conventionally, there are various types of bolts and shapes, and U-shaped bolts are also common. However, among U-shaped bolts, there is no belt-shaped U-shaped bolt that is tightened by making surface contact with the curved surface of the mounting surface.

[0003]

[Problems to be solved by the device]

 At present, removing the U-shaped bolts that are attached to pipes, etc., and looking at the places where they were attached, it can be seen that the contact surface on the pipe side that was fastened to the bolts has a shallow dent or groove. . This is because the bolt makes a line contact with the pipe surface, which is the mounting surface, and even if the nut tightening force is appropriate, the contact surface will be grooved or scratched, resulting in a drop in mounting strength. This will lead to pipe damage. In order to prevent this, it is conceivable to wrap rubber or something similar around the pipe-side or bolt-side contacting part, but this would be a costly process.

[0004]

[Means for Solving the Problems]

 In order to solve this, if the portion of the U-shaped bolt side that contacts the pipe surface is processed into a band shape and brought into surface contact and the nut is tightened with an appropriate force as in the conventional case, there is a concern that a groove or a scratch may occur. Is less.

[0005]

[Action]

 This is because the U-shaped band bolt tightens the contact surface of the cylindrical object over the entire band portion, as compared to the conventional line contact of the U-shaped bolt, and stable mounting strength is also obtained.

[0006]

【Example】

 A U-shaped band bolt with a shape as shown in Fig. (1) is manufactured by making surface contact with the curved surface of a cylindrical object that is the mounting surface and tightening it.

[0007]

[Effect of device]

 If you use U-shaped band bolts to attach parts to cylindrical objects, such as metal pipes, you will be less likely to have grooves or scratches on the contact surface on the pipe side, and more stable attachment strength will be obtained. To be In addition, the cost for repairing grooves or scratches on the contact surface can be saved.
