It is possible to know the magnitude of the gradient by reading the inclination of the liquid level in the container on the gradient scale.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a slope determiner useful when, for example, a drain pipe, a drain floor surface, or the like is provided with a gradient of a predetermined size, or when the gradient of an inclined surface is confirmed.

[0002]

[Prior Art]

 Conventionally, a spirit level is used to know the degree of inclination from the horizontal plane. In this system, bubbles are left in the glass tube to fill the liquid, and the presence or absence of inclination of the surface to be measured is known by observing the displacement of the bubbles from the horizontal position (reference position). .

[0003]

[Problems to be solved by the device]

 However, the conventional level only confirms whether or not it is horizontal, for example, whether or not the slope of the drain pipe is constructed according to the regular standard as designed. The size cannot be confirmed. Therefore, there was a problem that the quality of the drainage pipe construction would not be known until the actual water flow.

Therefore, the present invention has been made in order to solve such a conventional problem, and a scale for displaying a gradient is provided to specifically check the magnitude of the gradient of the object to be measured. It is an object of the present invention to provide a gradient determiner that can be used.

[0005]

[Means for Solving the Problems]

 To achieve the above object, the invention of claim 1 of the present application forms a space on the liquid surface by enclosing a liquid in an amount smaller than the inner volume of the container in a tubular container having at least one longitudinal side transparent. In addition, a horizontal line indicating the horizontal position of the liquid surface and a gradient scale indicating the degree of inclination from the horizontal line are displayed on the transparent side surface.

According to the second aspect of the present invention, at least one bubble is present in a tubular container having a transparent upper surface in the longitudinal direction to enclose the liquid, and the horizontal position of the bubble and the horizontal position The gradient scale showing the inclination of is displayed on the transparent upper surface side.

[0007]

[Action]

 In the case of the invention of claim 1, the bottom of the gradient determiner is placed on the inclination measuring portion, the inclination of the liquid surface is visually observed from the transparent side surface of the container, and the magnitude of the gradient is read by the displayed gradient scale. In the case of the invention of claim 2, the bottom of the gradient determiner is placed on the inclination measuring portion, the position of the bubble is visually observed from the transparent upper surface of the container, and the magnitude of the gradient is read by the displayed gradient scale.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the present invention, FIG. 1 is an overall perspective view, and FIG. 2 is a side view thereof. In the gradient determining device 1 of this embodiment, a rectangular tubular container 2 is made of transparent plastic, and water 3 in an amount smaller than the internal volume of the container is enclosed. Water may be colorless or colored, or may be a liquid other than water. The enclosed amount may be such that a space extending over the entire length of the container 2 is formed on the liquid surface 4 and the liquid surface 4 does not intersect the container ceiling surface or the bottom surface even when the container 2 is tilted in the longitudinal direction. .

A horizontal line 6 indicating the horizontal position of the liquid level 4 is displayed on one side surface 5 in the longitudinal direction of the container 2 (or both side surfaces facing each other), for example, a blue line over the entire length of the container. Further, as shown in FIG. 2, a gradient scale 7 indicating the degree of inclination from the horizontal line 6 intersects at the central portion of the horizontal line 6 and is a red line, for example, a gradient of 1/50, 1/100, etc. It is displayed with a numerical value.

When the slope determiner 1 configured as described above is used, for example, when determining the slope of a drain pipe, the lower surface 8 of the slope determiner is placed on the drain pipe, and the placed state The inclination of the liquid surface 4 at 4 is observed from the side surface 5 of the container 2, and the inclination of the liquid surface 4 and thus the magnitude of the inclination of the drain pipe can be read by the gradient scale 7. It is not always necessary to make the entire surface of the rectangular tubular container 2 transparent. For example, only the side surface 5 displaying the gradient scale 7 is formed of transparent plastic or glass, and the other surface is made of metal to ensure strength. It is also possible to consider such as.

If the lower surface 8 of the gradient determiner is not a flat surface but a concave curved surface as shown in FIG. 3 or a concave bent curved surface as shown in FIG. It has the advantage that it can be easily held parallel to the drainage pipe and the gradient can be measured more accurately. 5 and 6 show another embodiment of the present invention. This gradient determiner 11 is filled with a liquid 3 such as water and hermetically sealed in a container 12 made of a glass tube which is curved upward to some extent and leaves one bubble 14. Since the glass tube container 12 is easily damaged when hit, it is stored in a case 15 made of wood, metal, plastics or the like for protection, and a window 16 is provided on an upper surface 15a of the case 15 to prevent the container 12 from being damaged. You can see almost all of the upper surface of the. The container 12 is held so that when the lower surface of the case 15 is kept horizontal, the sealed bubble 14 stops at the apex of the curve of the container, that is, at the center position of the container length. As shown in FIG. 5, the position of the bubble 14 in the horizontal direction is set to 0 on the upper surface 15a of the case 15, and the gradient scale 17 indicating the inclination from the horizontal position is a numerical value of the gradient, for example, 1/100. , 1/50, 1/30, etc. are displayed.

When using the gradient determiner 11 configured as described above, for example, to determine the gradient of the drainage pipe, the lower surface of the case 15 of the gradient determiner is placed on the drainage pipe. Then, the bubbles 14 move in the longitudinal direction of the container 12 and stop in accordance with the inclination degree of the drainage pipe and the inclination direction (downward rightward, downward leftward), and the drainage pipe is read by reading the stopped gradient scale 17. The magnitude of the slope of can be determined by a specific numerical value. FIG. 6 shows how the bubbles 14 move in the container 12 according to the size of the gradient and display a predetermined gradient.

In the case of the second embodiment as well, the gradient scale 17 may be formed directly on the surface of the container 12.

[Effect of the device]

 As explained above, since the gradient determiner of the present invention has the gradient scale displaying the gradient, the degree of inclination of the DUT can be concretely confirmed on-site as a numerical value. It is possible to easily determine whether or not the work has been properly constructed according to the design criteria, and a great effect can be obtained on the improvement of construction quality, which was difficult in the past.
