Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a slope level for pipe slopes.

When installing sewage pipes, drainage pipes, etc., it is necessary to install the pipes at a certain slope so that the water will flow naturally.In order to create this slope, conventionally, the method of creating this slope was by attaching slope indication lines at predetermined intervals to the bubble pipe. When the edge of the bubble matches the indicated line due to the movement of the bubble enclosed in the bubble, the slope was measured, but it is not accurate as it is a visual measurement to determine whether the edge of the bubble matches the indicated line. Also, there was a drawback that piping work could not be carried out at an accurate slope due to deviations caused by viewing position and individual differences.

The present invention eliminates these drawbacks and provides a slope level that allows piping to have a desired slope using a simple method.

To explain the drawings showing the embodiment, reference numeral 1 denotes a horizontally rectangular spirit level body with an I-shaped cross section extending horizontally, and circular through holes 2, 2, 2 are formed in the center, front and rear of the body on the outer surface. A bubble tube 3 is placed in a horizontal state through a through hole 2 in the center, and its both ends are fixed through a protective cover 5 with a bubble 4 positioned in the center. be. In addition, a bubble tube 3 is fixed vertically to the front through-hole 2, and a bubble tube 3 is fixed at an angle of 45 degrees to the rear through-hole 2 by a protective cover 5 in the same manner as the above-mentioned bubble tube 3. be. Reference numeral 6 denotes a pedestal side plate that fits on one end of the level main body 1, and rectangular protrusions 7, 7 that protrude horizontally to one side are arranged in parallel at small intervals on the upper part of one side. Stepped sections 8, 8, 8, etc. are successively arranged downward with a height gradient of 10 mm for a height of 1 m as one step.
Similar to 7, they are arranged in parallel with small intervals. This stepped portion 8 is inclined to become slightly higher from the front to the rear, and each stepped portion 8, 8, 8
... have different inclination angles θ, θ, θ, etc., and the inclination angle becomes larger toward the upper step. 9 is a base plate fitted to the other end.

To explain an example of the use of the level configured in this way, as shown in FIG. 6, the pedestal side plate 6 fitted to one end of the level body 1 is removed from the level body 1, and the pipe body 10 is connected to the pipe body 10. When the lower surface of one end of the level main body 1 is placed on the upper surface and the lower surface of one end of the level is placed on the stepped portion 8 that matches the pre-specified slope, the pedestal will be tilted by the angle θ due to the inclination angle θ of the stepped portion 8. Since the bottom of the side plate 6 is inclined and comes into contact with the tube body 10, the tube body 10 is arranged to be inclined at a predetermined degree of inclination. In other words, if the lower surface of the level main body 1 is placed on the highest step 8 as shown in Fig.
This means that a slope with a height of mm has been added.

Although this application has described the spirit level body 1 having an I-shaped cross section, it is not limited to this, and for example, a spirit level body 1 having a square cross section may be used, and when this square shape is used, In this case, the locking protrusions and stepped portions of the pedestal side plate may be provided in a single row at the center of one side of the pedestal side plate.

In a spirit level in which bubble tubes 3, 3, 3 are attached to the outer surface of the horizontally elongated spirit level body 1, the bubble tubes 3, 3, 3 are arranged parallel to, at right angles to, and at an angle of 45 degrees to the upper surface of the spirit level body 1. At least one end of 1,
A projecting piece 7 that projects horizontally to one side is provided at the top, and at the bottom, step portions 8, 8, 8, 8, 8, 8, 8, 8, 8, 8... This relates to a gradient level formed by fitting a pedestal side plate 6 which is provided in a stepwise manner.
In addition to being able to accurately measure on horizontal surfaces, vertical surfaces, and 45-degree inclined surfaces, which are the original uses, one side end of the level main body 1 can be removed from the side plate 6 fitted at one end and placed at a predetermined step 8. If installed, it can be easily used as a slope level used for piping work to set a predetermined slope, and the slope angle increases as the slope increases upward. Since it is provided in a vertical manner, it is possible to easily set any number of slopes with a single touch as needed, and the work of setting slopes when working on plumbing such as sewer pipes and drain pipes can be done accurately and quickly.
