[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a measuring instrument equipped with a direct-connecting angle gauge capable of easily measuring the inclination angle of a building such as stairs.

[0002]

[Prior Art]

 It is often necessary to measure the tilt angle of a prefabricated building when installing a product on a prefabricated building, such as attaching a handrail to the stairs, or performing other modifications.However, conventional measurement of this angle is not possible. For example, in the case of the above-mentioned stairs, measure the length of the tread part of the stairs, the height of the riser part, the length of the stairs, etc., and write the dimensions on the paper, and calculate the angle on the paper. There is.

[0003]

[Problems to be solved by the device]

 However, it is said that the above-mentioned calculation method has many points that require measurement, and that it requires relatively complicated steps such as repeating the measurement in order to prevent the measurement error and the description error. There's a problem.

In view of such a problem, an object of the present invention is to provide a simple measuring device which can reduce the time required for measuring the tilt angle and at the same time can perform the necessary and sufficient measurement and has few errors.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a cylindrical column body in which a weight for instructing a vertical axis is suspended, and a measurement bar pivotally supported by the lower end of the column body. And an angle gauge plate fixed to the lower end of the column to indicate the tilt angle of the measuring bar.The column is erected vertically at the measurement reference point, and the measuring bar touches the DUT. An inclination angle measuring device is proposed in which the inclination angle of the measuring bar is read by the angle gauge plate.

[0006]

[Work]

 If the support bar is set up at the measurement reference point, and the support bar is held on the vertical axis indicated by the weight, and the measurement bar is brought into contact with the measured object, the measurement reference point and the contact point of the measured object are It is possible to read on the angle gauge plate the inclination angle of the measurement bar as the inclination angle of the measuring bar.

 Hereinafter, the present invention will be described with reference to the drawings illustrating embodiments. 1 is a partially broken perspective view showing a tilt angle measuring device of the present invention when measuring a tilt angle of a staircase, and FIG. 2 is an enlarged side view of the tilt angle measuring device of FIG. 1 with a part cut away. FIG. 3 is a sectional view taken along line III-III in FIG.

A is a tilt angle measuring device, and the column body 1 is made of an aluminum alloy and has an outer dimension of 60 mm and a total height of about 1800 mm. The column body 1 has a hemispherical projection at the lower end. A lower cap 2 having a portion 2a is fitted and fixed, an upper cap 3 is fitted on the upper end, and the upper cap 3 is slung down to the center of the inside, that is, a conical weight 4 is suspended. Thread 5 is attached.

Further, one side of the middle portion of the column 1 is cut off, and a transparent acrylic plate 6 is attached to the inside to form a window 7. The transparent acrylic plate 6 is engraved with a gauge line 8 along the axis of the column body 1, and the tip of the suspended conical weight 4 is superposed on the gage line 8 when viewed from the front. It is determined that the pillar 1 is positioned in the vertical direction.

A shaft 9 is provided at the lower end of the support column 1 to pivotally support one end of a long measuring bar 10 so that the measuring bar 10 is rotatable, and an angle gauge is provided on the front surface of the measuring bar 10. The plate 11 is coaxially screwed. The measuring bar 10 is made of an aluminum alloy strip with a width of 50 mm, and a scale is engraved on the surface so that the linear length dimension can be measured.The angle gauge plate 11 is an aluminum alloy plate. To form an approximately quadrant circle, and engrave a 90-degree angle scale around the axis of the shaft 9 on the arc edge, and fix it so that the horizontal direction is 0 degrees and the vertical direction is 90 degrees. There is.

Further, a hook 13 formed on the center line 12 of the measuring bar 10 is screwed so that a part of the needle 13 covers the arc edge of the angle gauge plate 11. The scale of the angle gauge plate 11 is indicated by the tip of the.

The inclination angle measuring device A of the present invention is constructed as described above, and as shown in FIGS. 14a, 14a, ... While being brought into contact with the cone body 4, the conical weight 4 of the support body 1 is aligned with the gauge line 8 and the support body 1 is held vertically at the measurement reference point 15. The inclination angle α of the stairs 14 can be measured by reading the scale α on the angle gauge plate 11 indicated by the pointer 13. At the same time, if the distance d between the noses 14a, 14a is read by a scale on the measuring bar 10, the required shape and size of the stairs can be transferred together with the inclination angle α.

It should be noted that the angle gauge plate 11 is formed in a substantially semi-circular shape, and an angle scale for 180 degrees is engraved so that the measuring bar 10 can be measured on both the left and right sides of the support column 1. Good. Further, the projection at the lower end of the support column 1 is not limited to a hemispherical shape, and may have an inverted conical shape or an inverted pyramid shape with a pointed end.
