The present invention relates to the installation dimension measuring device of the base of the steel tower base, more specifically, when constructing the square tower of the power line support of the overhead transmission facility, the angle of the angle of the foundation affects the assembly process of the steel tower and each member after assembly, etc. Considering this, the item requires a very precise value up to 1mm, but one of the three items related to the length dimension at the time of the entrance can be measured by using a general measuring instrument and a tape measure. Is required for re-installation of plinths in accordance with special conditions consisting of curved surfaces that cannot be measured by ordinary rulers that are not planes or planes where objects do not exist, but to date, there are no detectors that can be easily measured and correspond to the conditions of use. As it is measured by quoting a general instrument, there is a case of rework due to a lot of time and errors. In order to prevent this problem, it is related to the plinth member installation person who can directly construct and inspect the rotational and inclination values of the plinth material required by the design drawings and specifications of the basic angular work up to millimeters.

1 is a front view of a transmission pylon assembled by joining a base portion and an upper end portion, FIG. 2 is a detailed plan view of four basic portions installed in FIG. 1, and FIG. Figure 4 is a detailed measurement, Figure 4 is a detailed side view of the measurement of the slope of the prior art in the lateral enlarged part of the plinth.

The steel tower configuration of the overhead power line support of the overhead power transmission facility is roughly divided into a base part 2 on the lower side and an upper end part 3 on the upper side with respect to the ground surface 1 as shown in FIG. The joint part 4 between the base part 2 and the upper and lower part 3 of the upper part 3 is fastened with several bolts, and the structure is completed.

In addition, since the leg 5a of the base portion 2 is composed of four legs individually as shown in Fig. 2, the angle of the angular dimensions so that the joint is well formed at the joint 4 between the bottom and the top of each leg. Precision is required. Therefore, as shown in FIG. 3, the rotation 10 value 9L-9R and the plinth that are the difference between the left length 9L and the right length 9R with respect to the pleats 5a direction reference virtual line 9a. It is essential to construct a slope 11 value error range within ± 1 mm, which is the length from the upper end to the thread 6 b vertically down to 1 m and the length of the inner curved surface 5b of the shell material.

As shown in Fig. 3, the plinth ash rotation 10 is a space 9a, 9b, 10 in which the diagonal surface side of the center direction 9a of the pylon, which is the object of the measurement position, is a space where no object exists, and thus there is no plinth ash. Measure the measuring point (9b) by quoting the seal (6a) at the top, then display the virtual reference line (9a) and measure the straight line (5b) and the straight point of the plinth at the pylon center point (12a). The measurement point 9b is displayed on the display point construction thread 6a, and the diagonal thread length from the thread display point 9b to the left plinth blade side curved surface 5c, and the right plinth member from the thread display point 9b. By measuring the diagonal length to the common side up to the blade side curved surface 5c, the measured plinth recline measurement value 11 can be obtained. At this time, the length difference (9L-9R) between the seals (6a) between the two sides is the shell material rotation value (11) and the tolerance should be within ± 1mm. However, the process of marking the reference point on the yarn 6a and the shape of the plinth blade side form a curved surface 5c rather than a plane, thereby causing an error such as uncertainty in application of the yarn length measurement position.

As shown in Fig. 4, the measurement of the inclination of the plinth material 11 is performed by attaching a weight 7 perpendicularly from the inner surface 5d of the plywood material upper portion 5b to the normal 1 m point to be measured, and the yarn 6a. After the installation, the diagonal length 11 between the inner surface 5d of the shell material and the seal 8b shall be measured. However, since the inclined state and the inner surface shape of the plinth material form a curved surface 5d rather than a flat surface, a gap is generated because it is not in close contact when measuring with a common ruler, and thus it is impossible to measure directly. Therefore, the measurement result can be obtained by first quoting an instrument similar to the wire 8a or the like and displaying the measurement value 8b on the instrument, and then converting the instrument length cited by the general public. At this time, design dimension and tolerance shall be installed within ± 0.4㎜. However, since the measurement is not done directly, but the instrument is indirectly measured, the value (11) can be obtained by indirect measurement in two steps, such as when displaying the cited instrument and converting the instrument displayed next to a general person. There was a problem that occurred.

An object of the present invention was devised to solve the conventional problems as described above, when installing the plinth material of the iron tower-based angular work, so that the length of the plinth material rotation and inclination can be directly and accurately measured without interfering with the measurement position and shape, etc. It is to provide castor installation holders that can be constructed and inspected to fit design documents up to 1mm.

In order to achieve the above object, the pylon shell material installer according to the present invention, in the construction of the overhead transmission tower, in the measurement of the rotation and the inclination of the shell material used for the construction and inspection of the basic engraving work, A body is formed of a right isosceles triangle, an isosceles slope measurement scale is formed on an isosceles of the right isosceles triangle, an isosceles slope measurement scale is formed on one isosceles of the right isosceles triangle, and a plinth material is formed on another isosceles of the isosceles triangle. A width scale portion is formed, a plinth material rotation reference scale is formed by a line connecting the inequality side from the vertex of the equilateral edge, a plinth material rotation measurement scale is formed on both sides of at least two portions of the reference scale portion, and the Plinth rotation angle measurement eye on both sides of one part of reference scale It characterized in that portions are formed.

Here, in the above-described iron tower shell material installation rule, it is preferable that at least one or more handling holes are formed in a predetermined space where the scales are not formed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 5 is a detailed front view of the ruler according to the present invention, Figure 6 is a detailed rear view of the ruler according to the present invention.

As shown in Figure 5, the pylon shell mounting material according to the present embodiment is made of stainless steel having a thickness of 1.2mm, the overall shape is formed of a right angle isosceles triangle.

An isosceles slope measurement scale 106b is formed on the isosceles of the isosceles triangle.

An equilateral slope measurement scale section 106a is formed at one equilateral side of the isosceles triangle, and a plinth width scale 108b is formed at the other equilateral side.

In addition, a water line is formed to connect the inequality from the vertex of the equilateral side, which becomes the plinth rotation reference scale 102. Four shell material rotation measurement scales 103a to 103d are formed in the plinth material rotation reference scale 102, where 103a is the rotation measurement scale for the plywood width 150mm, and 103b is the rotational measurement for the plywood width 175mm. It is a scale, 103c is a rotation measurement scale for plinth width 200mm, and 103d is a rotation measurement scale for plinth width 250mm. However, the present invention is not particularly limited to the number and measurement limits of the four cast iron rotation measuring scales, it should be noted that the number of cast steel rotation measuring scales may be added or deleted as necessary, and the measurement limits may be changed. do. In addition, the plinth rotation angle measurement scale 102 is also formed on the plinth rotation angle measurement scale 109. Although the main body rotation angle measurement scale part 109 is shown to +/- 5 degrees in FIG. 5, this invention is not specifically limited to this. Here, the scale of the ruler is 1 millimeter in length and 30 minutes in minutes.

As shown in FIG. 6, the 'steel tower angle error reference value' may be engraved on the rear surface of the pylon tower material installing member 100. That is, the use method, the measuring method, etc. of the pylon shell material installation ruler 100 according to the present embodiment can be engraved as necessary on the back.

In addition, the steel tower shell material installation ruler (100) is provided with handling holes (101a, 101b, 101c). Ease of Handling The holes are 25mm 18mm 18mm in diameter and can be used for storage, transportation, construction and inspection. Similarly, the number, dimensions, and the like of the handling convenience holes may be appropriately changed as necessary or required.

Referring to the function of each component, first, the base material rotation reference scale 102 becomes the base material rotation reference line. Pleating material rotation measurement scales (103a, 103b, 103c, 103d) are displayed to the left and right 20mm to the base material rotation reference graduations 102, and directly to the left and right rotation angle value relative to the rotation reference line (102). It can measure from within mm to 20mm. Since the slope measurement scales 106a and 106b start from an isosceles vertex to an isosceles vertex, respectively, from an isosceles vertex to an isosceles vertex side, utilizing the sharp shape of the isosceles vertex, the slopes of the plinth material slopes 106a and 106b are curved. Since it is in close contact without the occurrence of the gap, the plinth inclination 107 can be measured directly to 380 mm. Since the plinth width measuring division 108b is displayed starting at the equilateral vertex and up to 260 mm toward the isosceles vertex, the dimensions of the plinth width 108a are measured when the ruler is connected during rotation measurement. The pillar material rotation angle measurement scale 109 may measure the angle of the pillar material rotation to 5 degrees in units of 30 minutes left and right of the pillar material rotation reference scale. The engraved contents on the back side can be, for example, the contents of the angular error standard value of the KEPCO's steel tower construction standards, so that the contents can be understood by the handlers.

In the following, with reference to Figures 7 and 8 will be described how to use the pylon shell mounting material according to this embodiment.

7 is a detailed view of a rotation measurement method corresponding to FIG. 3 using a ruler according to the present invention, and FIG. 8 is a detailed view of a tilt measurement method corresponding to FIG. 4 using a ruler according to the present invention.

As shown in Fig. 7, the measuring method of the plinth re-rotation 105 is because the plinth material width is measured by the plinth material width scale 108b when the measuring device is connected so that the vertices of the equilateral sides coincide with the inside of the top of the plinth material. You will know the width of the plinth. If the width of the plinth is 150 mm from the center of the tower to the instrument 12b, the value of the plinth rotation measurement scale 103a is 150 mm, and the value of the plinth rotation measurement scale 103b is 200 mm. The shell material rotation measurement scale section 103c, and 250mm, the shell material rotation measurement scale section 103d may be read to the left and right units within the left and right units from the shell material rotation reference scale section 102, respectively. At this time, the read scale is the rotation value 105 of the plinth (5a) and the error range should be within ± 1 mm regardless of the width of the plinth.

As shown in Fig. 8, the method of measuring the slope 107 of the plinth material 5a is based on the gradient measurement scales 106a and 106b from the center of the plinth material 5a to the yarn 6b from the center of the inner curved surface 5b. Read directly in 1mm increments. At this time, the read scale is the slope value 107 and the error range should be within ± 0.4mm per 1m of the plinth.
