Description

  The present invention relates to a plumbing tool for joining pipes at a specific angle during plumbing for water drainage.

When performing piping work to arrange drainage pipes for drainage, piping must be provided with a certain gradient in order to ensure that drainage flows from upstream to downstream without stopping. Since the drainage pipe is installed in a narrow space such as under the floor, in order to install the drainage pipe in a narrow space with a certain gradient, the drainage is surely made with the smallest possible gradient. It is necessary to make the gradient flow from upstream to downstream. As a gradient having such a condition, a gradient of 1/50 (gradient that makes a difference in height at a rate of 1 meter per horizontal distance of 50 meters) is generally used. Further, as disclosed in Non-Patent Document 1, dedicated elbows and cheeses are commercially available as piping materials used when piping with a 1/50 gradient.
A gradient of 1/50 with respect to the horizontal direction corresponds to an angle of 91 degrees and 10 minutes with the vertical direction.

It is installed on an orthogonal plane.

First, a method for cutting a pipe into a predetermined length by a conventional method will be described.

In FIG. 9, 901 is a pipe to be cut, 506 is an elbow that fixes the end of the pipe that is not to be cut, and L is a position to be cut from the right end of the pipe 901 to be cut. 904 is a level, and 910 is a pipe to be connected. Reference numeral 510 denotes a cheese for connecting pipes, and 520 denotes an end of the receiving hole of the cheese 510.

  In order to cut the pipe to a predetermined length by the conventional method, first, temporarily fix one end of the cutting target pipe 901, and then adjust the gradient of the cutting target pipe 901 to 1/50, It is necessary to find the length L. However, fixing the opposite end of the side to be cut with an elbow, maintaining the slope of the pipe at 50: 1, applying the cheese to be used for the pipe, and measuring the length L, The reference position of L is inside the cheese 510 and is not visible from the outside. Therefore, the length to the end 520 of the cheese receptacle visible from the outside is measured, and the length L is obtained by adding Z of cheese to the length. This operation must be performed while maintaining the slope of the pipe at 50: 1, which is likely to cause errors in measurement.

Next, a method of cutting a pipe into a predetermined length using the pipe pipe angle fixing ruler according to the present embodiment will be described.
FIG. 10 is a perspective view for explaining a method of cutting a pipe into a predetermined length using the pipe pipe angle fixing ruler according to the present embodiment.

The opening 104 of the pipe pipe angle fixing ruler according to Embodiment 1 of the present invention is such that the position of the opening 104 should be cut when the pipe to be cut is inserted into the first holding part. It is installed to match. In order to match the positions, as shown in FIG. 1, the opening 104 starts from the intersection 113 between the center line 111 of the first holding part and the center line 112 of the second holding part. The center of the first holding part is separated by the length of Z described in the catalog of cheese joints used for connecting the first pipe and the second pipe in a T shape on the center line of It is provided on a line where a plane perpendicular to the line intersects with the cylinder constituting the first holding part. Note that the opening may be provided locally like the opening 104 or may be a large size like the opening 105. The important point is that it should be configured so that a mark can be made at the Z position of the pipe.
The opening 105 in the pipe pipe angle fixing ruler according to Embodiment 1 of the present invention is configured such that a mark can be made at the Z position of the pipe using one of the ends of the opening 105. .

  Therefore, when the pipe is cut using the pipe pipe angle fixing ruler according to the present embodiment, it is not necessary to measure the length L after the pipe 901 is set in the state shown in FIG. The pipe may be marked and cut with reference to the portion 104. In order to set the slope of the pipe 901 to 50: 1, it is only necessary to make the pipe 910 vertical. This is because the angle X is 91 degrees and 10 minutes, so if the pipe 910 is made vertical, the pipe 901 automatically has a gradient of 1/50 with respect to the horizontal direction. The gradient of 1/50 is 91 degrees and 10 minutes in angle.
