DESCRIPTION OF THE PREFERRED EMBODIMENTS The vertical measuring method according to the present invention relates to a method for measuring an inclination angle in order to vertically stand a column P having a conical side surface such as an illumination pole. That is, a pair of right-angled L-shaped arms each having a length of one side longer than the radius of the column P is used, and one side of each L-shaped arm is brought into contact with the opposite side of the cross section at an arbitrary height of the column P. When the other side of each L-shaped arm is connected and brought into contact with the same side surface of the cylinder, the orthogonal portion of each L-shaped arm is defined as a measurement point. Then, on an extension line extending from the center of the cylinder P in the direction of the measuring point, a pair of spirit levels 10 for measuring the left and right inclination angles without interfering with the inclination of the front and rear of the cylinder P is installed, and the front face of the level is a cylinder. From the center to the radial direction,
The inclination angles of the pair of spirit levels 10 are simultaneously measured to measure the inclination angle of the column P having a conical side surface.

FIG. 6 illustrates the principle of the vertical measuring method according to the present invention. That is, as shown in FIG. 2A, a cone is assumed to be a column P such as an illumination pole, and a quadrangular pyramid circumscribing the column P is assumed. At this time, the central axes of the cylinder P and the quadrangular pyramid coincide. Then, the ridge line direction (A
Seeing from (arrow view), it is as shown in FIG. Next, when viewed from the direction of the ridge line of the quadrangular pyramid, the central axis of the cone and the ridge line of the quadrangular pyramid appear to coincide. That is, the cylinder P can be made vertical by correcting the inclination angle from each of the two directions of the ridge line direction in FIG. Therefore, as shown in FIG. 3 (C), the three faces of the U-shaped arm (reference signs I, B, C) respectively contact the cylinder P with lines (surfaces), and the cylinder P tilts. On the arm having a slide mechanism corresponding to the diameter of the cylinder P, place a level 10 that is always vertical
Arrange two at a time. Thus, the verticality from the XY axis directions can be viewed without correction. When this principle is further confirmed, as shown in FIG. 3C, in the cross section of the cylinder P, when the length of one side including a 90-degree angle is longer than the radius of the cylinder P, the surface of the cylinder P At 90 degrees apart from each other (symbols A and C). The inner side surface of this arm is obtained by cutting out the surface of a quadrangular pyramid circumscribing the cylinder P (reference numeral a in the figure (b)). If an arm sharing one side of this arm by sliding is provided and the other side is brought into contact with the cylinder P, the cylinder P and the quadrangular pyramid are coaxial, and vertical reference can be set.

The basic construction of a pole-building vertical instrument for implementing the vertical measuring method according to the present invention includes a pair of fixed arms 1, a connecting body 2 connecting the fixed arms 1, and a pair of spirit levels mounted on the fixed arms 1. 10 (see FIG. 1).

The fixed arm 1 uses the opposing side surfaces of the cross section at an arbitrary height of the erected column P as contact points, and sandwiches these contact points along the conical side surface. At this time, the fixed arm 1 is formed so as to have a width that makes surface contact along the upper and lower sides of the column P (see FIG. 2). The fixed arm 1 includes a magnet 1A magnetically attached to the side surface of the column P.

A mounting body 1D for mounting the level 10 is extended from the plate body 1B. The mounting body 1D includes an extension arm 1E connected to the plate 1B, and a mounting board 1F fixed to the extension arm 1E. The mounting board 1F is provided so that the front surface of the level 10 can be disposed at an angle of 90 degrees from the core of the cylinder P (see FIG. 1). Furthermore, in order to achieve compactness, the mounting board 1F is detachably connected to the extension arm 1E with a thumb screw or the like.

The connecting bodies 2 extend at right angles from the fixed arms 1 and connect the fixed arms 1 to each other so as to be able to adjust the distance therebetween.
It comes into contact with the other side surface of the column P, and is provided to bend freely corresponding to the taper angle of the cone (see FIG. 3). The connecting body 2 shown is formed integrally with one fixed arm 1,
The connecting body 2 and the fixed arm 1 are kept at right angles. The connecting body 2 is also provided with a magnet 1A magnetically attached to the column P to facilitate the work of mounting the fixed arm 1 and the connecting body 2. Also, the other fixed arm 1
Is slidably connected to one of the connected bodies 2 by a slide pin 2A. The slide pin 2A is fixed to an elongated slide hole 2B formed in the connector 2 and the connector 2 is freely bendable in the vertical direction at the connection position of the slide pin 2A ( (See FIG. 3).

The level 10 measures the left and right inclination angles without interfering with the front and rear inclinations thereof (see FIG. 4). The level 10 shown is of a type in which a level scale 10A swings left and right, and is not affected by the inclination of the level 10 in the front-rear direction. Then, a pair of spirit levels 10 are disposed outside the position where the fixed arm 1 and the connecting body 2 are orthogonal to each other, and
The front of the level 10 is directed radially from the center of the cylinder P. By arranging the pair of spirit levels 10 in this manner, one level 10 measures the left and right inclination angles without interfering with the front and rear inclinations of the column P, and the other level 1
0 measures the front and rear inclination angles without interfering with the left and right inclinations of the cylinder P. In the illustrated example, this level 10
The support rod 10B provided at the upper end of the mounting board 1F is detachably suspended on the support member 1G of the mounting board 1F.

Reference numeral 11 denotes a cover that covers the level 10 and is used for waterproofing and windproofing (see FIG. 4). The cover 11 is provided with a lens 12 on the front surface of the cover 11 so that the level scale 10A of the internal level 10 can be easily checked.

FIG. 5 shows a state in which the vertical device of the present invention is mounted on a column P. In this manner, the column P can be made vertical by simply mounting it at an arbitrary height of the column P.
It does not require correction of the taper of the cone.

[0024]
