[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal indicator for obtaining a horizontal level at a construction site or the like, and more particularly to an improved horizontal indicator structure capable of easily obtaining a horizontal level.

[0002]

[Prior art]

 For example, when building a foundation or floor at a construction site or construction, it is necessary to obtain an accurate horizontal state (horizontal plane). Conventionally, in order to obtain such levelness, for example, as shown in FIG. 7, a leveler in which a liquid 2 is enclosed inside a cylindrical tubular body 1 having a transparent outer periphery is used. When leveling using this conventional leveler, piles are erected at the ends of the foundation or floor, and a thread called water thread is stretched between these piles to form the foundation or floor. A decision is being made. In order to confirm the parallelism of the set surface, the leveler should be placed on the surface, and the bubbles 3 enclosed with the liquid 2 inside the cylindrical tube 1 should be in the center of the cylindrical tube 1. Was checked and the horizontal state of the setting surface was checked.

[0003]

[Problems to be solved by the device]

 However, in the leveler according to the prior art described above, after deciding the position where the foundation or floor surface is to be constructed by stretching the water thread in advance, the leveler is placed on this positioned surface to check the horizontal state. If not, the above operation needs to be repeated many times. In other words, in order to obtain an accurate level, it is necessary to repeat the setting of the position of the base and the floor while trial and error. There was a drawback that the setting was troublesome.

Therefore, in the present invention, it is possible to improve the drawbacks of the leveling device according to the above-mentioned conventional technique, and thus to easily set the horizontal position with simple operation and without the need for repeated trial and error. The aim is to propose a possible improved horizontal indicator.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, according to the present invention, a liquid is enclosed in a cylindrical tubular body having at least a transparent outer periphery, and a leveler in which bubbles are present in the liquid is provided. A horizontal indicator is proposed in which a guide for threading is formed on the central axis of the cylindrical tube of the transparent tube.

[0006]

[Action]

 That is, according to the horizontal indicator of the present invention described above, instead of confirming the horizontal state of the surface placed on the set surface as in the conventional case, the cylindrical tubular body of the transparent tube of the leveler is used. By passing a thread through a guide formed on the central axis of the, it is possible to easily check whether or not the thread itself is stretched horizontally when the thread is stretched. Therefore, it is possible to easily set parallel planes such as the base or floor by using the water thread whose horizontal state has been confirmed.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 and 2 show a horizontal indicator which is an embodiment of the present invention. In the drawings, the horizontal indicator 10 includes a transparent tube 11 formed of, for example, glass or transparent plastic in a cylindrical shape. It has a so-called leveler in which the liquid 12 is enclosed and bubbles 13 are present in the liquid 12. The bubbles 13 in the liquid 12 are separated from the liquid 12, and because of their lightness, they are always located above the liquid 12. Therefore, when the transparent tube 11 is horizontally positioned horizontally, the bubbles floating above the liquid 12 are located in the central portion of the transparent tube 11, and this is attached to the outer peripheral surface of the transparent tube 11. Check that it is horizontal while checking it with the indicated lines 14, 14.

According to the present invention, the pipe-shaped guide 15 is provided along the central axis of the cylindrical shape of the transparent tube 11 of this leveler, that is, along the center of the circular cross section. That is, a line of water thread can be passed through the through hole 16 at the center of the guide 15.

Next, a method of setting a horizontal plane using the above-described horizontal indicator according to the present invention will be described below with reference to FIG. First, the water thread 20 is passed through the through hole 16 at the center of the guide 15 provided along the central axis of the transparent tube 11 of the horizontal indicator. Then, as shown in the figure, this water thread is fixed on the piles 30 and 30 which are erected at both ends of the place where the base or floor is to be constructed, for example. After that, the position of the bubble 13 floating on the liquid 12 enclosed in the transparent tube 11 of the horizontal indicator located on the water thread 20 is set to the central portion of the transparent tube 11 by the instruction lines 14, 14 ,. While confirming that there is one, the position (height) is determined while vertically adjusting the height of one of the water threads 20 (in this embodiment, the left pile 30). As a result, the water thread 20 is accurately in a horizontal state, and horizontal positioning of the water thread 20 can be easily performed.

FIG. 4 shows another embodiment of the present invention. In this embodiment, a precision leveler 30 having an outline "B" shape is further combined below the level indicator shown in FIG. As is clear from the figure, the precision leveler 30 has a transparent tube 31 formed of a transparent member such as glass or plastic in the shape of a cylinder and formed into a substantially "B" shape. The floats 33 and 33 are housed in the vertical pipes 31 ′ and 31 ′ on both sides of the float 33. In addition, on the outer peripheral surfaces of these floats 33, 33 and on the outer peripheral surfaces of the vertical tubes 31 ', 31' of the transparent tube, there are well-known scales such as the so-called 39 to 10 (39/10) scale on the principle of calipers. These marks are marked 34 and 35, respectively, in the figure. It should be noted that these scales 34 and 35, in a precise horizontal state, have vertical scales 31 ′ and 31 ′ on both sides thereof with a scale “0” on the outer peripheral surface of the float 33, respectively. It is engraved so that it exactly matches the scale "0" on the outer peripheral surface.

An example of an operation for obtaining parallelism using the horizontal indicator according to another embodiment of the present invention will be described with reference to FIG. First, in the same manner as shown in FIG. 3 above, a water thread is passed through the through hole 16 of the guide 15 of the parallel indicator, and the water thread is stretched between the piles standing at predetermined positions. After that, the horizontal state is confirmed by the horizontal indicator, but in the other embodiment, first, the horizontal state is roughly confirmed by using the leveler 10. Then, using the precision leveler 30 described above, the parallel state is precisely confirmed.

That is, as shown in FIG. 5, the numerical value of 1 mm or more is read by the scale 35 on the vertical pipe 31 ′ side corresponding to the position where the scale 34 on the float 33 side indicates “0”. Next, the value of 0.1 mm of the scale 35 on the vertical pipe 31 'side is read by the scale 35 on the float 33 side which matches either the scale 34 on the float 33 side and the scale 35 on the vertical pipe 31' side. Further, the height of the water thread is adjusted until the scale “0” on the side of the float 33 and the scale “0” on the side of the vertical pipe 31 ′ exactly match on the vertical pipes 31 ′ and 31 ′ on both sides. Continue. This allows precise leveling.

In the above-mentioned other embodiments, the scales provided on the outer peripheral surfaces of the float 33 and the vertical pipe 31 ′ are not limited to the above-mentioned 39/10 scales, and other scales such as 19/20, 12/25, A scale such as 49/50 may be used.

[Effect of device]

 As is clear from the above detailed description of the present invention, the horizontal indicator according to the present invention makes it easy to obtain a horizontal line segment simply by passing the water thread through the guide, and thus it is accurate. It will be possible to easily perform setting and dimensioning work such as the base and floor that require a horizontal state.
