[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig used for cutting a member having a circular or arc-shaped cross section, such as a pipe for piping or a rain gutter, with a saw.

[0002]

2. Description of the Related Art A resin pipe formed of vinyl chloride or the like is often used for water plumbing, and a saw for cutting the resin is used for cutting such a pipe. However, in the prior art, after marking the cut portion of the pipe, the cutting work is actually performed without using a special jig or the like.

[0003]

However, when a pipe is cut at the time of water supply plumbing, etc., an "L" -shaped or "T" -shaped joint, a faucet socket or the like is usually attached to the end. However, if the cut end of the pipe is not cut vertically, a gap is formed at the boundary between various joints, which impairs the appearance. In particular, when cutting a large-diameter pipe, the slight deviation at the beginning of cutting becomes gradually larger as it goes down, and when a joint is attached, a large gap is created on the upper side or the lower side.
On the other hand, in this type of resin pipe, the inside is hollow, so there are few parts to guide the saw blade,
Unless the cutting work is performed with constant care, it is difficult to make a vertical cut in a straight state, and because the cross-sectional shape is circular, the entire cutting location is marked with a curved scale and the cutting work is performed. It cannot be said. The present invention relates to a jig used for cutting a member having a circular cross-section such as a pipe for a water supply pipe or a gutter such as a rain gutter. The purpose of this is to make it easy to make a straight vertical cut.

[0004]

The present invention is used for sawing a member such as a pipe having a circular cross section or a member having a circular cross section such as a rain gutter with a saw. It relates to a jig, and forms a block portion having a saw blade guide groove arranged vertically at an end of a grip portion, and an inverted " It is intended to make it possible to perform accurate vertical cutting by adopting a configuration formed in a “V” shape.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of the present invention will be described. As shown in FIG. 1, a jig body 1 has a grip portion 3 having an upper surface in a semicylindrical shape, and an end of the grip portion 3. And a saw blade guide groove 5 arranged in the vertical direction at the center of the block portion 2, and a contact portion 4 to a pipe or the like is formed at an upper portion. Are formed in an inverted “V” shape having a narrowed shape. The jig body 1 according to the present invention has such a configuration, and is used in the manner shown in FIG. That is, an inverted “V” -shaped notch formed in the pipe cutting jig main body 1 is applied to an arc portion on the upper surface of the pipe 7 to be cut, and a saw formed in the block portion 2. Insert the blade guide groove 5
After matching the position to be cut in the pipe 7, the saw blade 6 is inserted from the near side of the saw blade guide groove 5 formed in the block portion 2, and the entire saw is reciprocated back and forth in the same state. It is done.

[0006]

The jig body 1 for cutting pipes and the like according to the present invention has the above-described configuration, and can accurately cut pipes for water pipes and rain gutters. As a result of the abutting portion of the main body 1 contacting a pipe or the like being in an inverted “V” shape, it can be arranged in a stable state with respect to a pipe of any thickness. This has the advantage that the cutting operation can be performed efficiently without causing the clogging phenomenon due to the discharged chips. That is, if the shape of the joint to the pipe etc. in the jig is flat as seen in the conventional jig, the jig itself lacks stability at the time of cutting, and the jig must be used. Although it does not make much sense itself, and even if it can be used, it will not be possible to efficiently discharge chips generated at the beginning of pulling, resulting in a clogging phenomenon, but according to this invention In the jig, the abutting portion for the pipe or the like is formed in an inverted "V" shape, so that even when cutting a pipe of any thickness, a clogging phenomenon may be caused. There is nothing.
By the way, when trying to cut this kind of pipe with a saw, a large amount of chips will be generated at the beginning of the drawing, but at this time, the lower end of the saw blade guide groove will be in contact with the pipe. In such a case, a large amount of chips lose their place to go and enter a saw or a guide groove. However, in the jig according to the present invention, an abutting portion to a pipe or the like has an inverted “V” shape. This has the advantage that the clogging phenomenon at the time of cutting can be prevented.
