Description

  In the present invention, when a hole for a foundation bolt is drilled on a foundation for a wooden building placed on the top surface of the foundation, the actual position of the foundation bolt can be marked on the foundation accurately in the field. It relates to the music scale.

In order to fix the foundation to the foundation, many foundation bolts protrude from the top of the foundation. In addition, a black line indicating the position at which the base is placed is marked on the top surface, and it is necessary to align the side of the base with the black line and install it on the base.
Conventionally, when making a hole for a foundation bolt in the foundation, the foundation is placed on the top surface of the foundation, and the foundation is temporarily placed in parallel with the black line. Then, measure the distance between the outer surface of the foundation bolt and the black line (hereinafter referred to as the “bolt outer surface distance”) after applying the tape measure to the foundation bolt, and then calculate the value obtained by adding the radius of the foundation bolt to the bolt outer surface distance. This is the distance between the center of the foundation bolt and the black line (hereinafter referred to as “bolt center distance”).
In addition, regarding the center position of the foundation bolt in the base line direction (hereinafter referred to as “the ink line direction bolt position”), a mark (such as a ruled line or arrow) (hereinafter referred to as “curved line”) is visually aligned with the center of the foundation bolt. It was called “ruled lines”. However, it has been difficult to accurately align the tape measure with the center position of the foundation bolt.

If the scoring of the position of the ink line direction bolt is not accurate, the arrangement of the foundation bolt and the arrangement of the bolt hole provided in the base do not meet, and the foundation bolt cannot be inserted into the bolt hole of the foundation. Also, if you make a mistake in calculating the value of the bolt center distance by adding the radius of the foundation bolt to the bolt outer surface distance, when you insert the foundation bolt into the bolt hole and place the foundation on the top of the foundation, The positions of the ink line and the side of the foundation do not match. In such a case, it was necessary to redo the bolt holes in the base.
Moreover, since there are many foundation bolts, the calculation which calculates the value of bolt center distance for every foundation bolt is troublesome. For this reason, it has been desired to be able to mark the position of the foundation bolt on the base accurately and quickly.
Conventionally, there has been a device in which a cutout portion is provided at an outer corner portion of a curved scale (see, for example, Patent Document 1). However, such a device can firmly press the curved scale against a measured object and cut the measured object. This was a device that did not contribute to accurately marking the center position of the foundation bolt. Moreover, the notch part of the device according to Patent Document 1 is merely provided to accurately bend the guide / contact plate.

  The objective of this invention is providing the tape measure which does not require the operation | work which calculates the value of a bolt center distance by adding the radius of a foundation bolt to the bolt outer surface distance. It is another object of the present invention to provide a tape measure that enables accurate marking of the ink line direction bolt position.

  In a curved scale having a main branch part and a wife branch part, the intersection of the outer edge of the main branch part and the outer side of the wife branch part is defined as a curved scale angle, and the missing wife side and the main branch parallel to the wife branch part at the curved angle part. A notch having a notch main side parallel to the part is provided, the origin of the scale provided on the outer side of the main branch part is the curvature angle, the origin of the scale provided on the outer side of the wife branch part is the missing main side, and The length of the missing main side is half the nominal diameter of the foundation bolt.

Since the length of the missing main side is half the nominal diameter of the foundation bolt, when the missing edge is applied to the outer surface of the foundation bolt, the scale provided on the center of the foundation bolt and the outer side of the main branch The origin matches. For this reason, it was possible to obtain the value of the bolt center distance without performing any calculation only by reading the scale provided on the outer side of the main branch.
Also, since the length of the missing main side is half the nominal diameter of the foundation bolt, when the missing wife side is applied to the outer surface of the foundation bolt, the extension of the center of the foundation bolt and the outer edge of the wife branch The lines coincided with each other, and the marking of the bolt direction bolt position with respect to the base could be accurately and easily performed.

A curved scale having a main branch part and a wife branch part, where the intersection of the outer side of the main branch part and the outer side of the wife branch part is a curved scale angle, and the missing wife side parallel to the wife branch part at the curved scale part And a notch having a notch main side parallel to the main branch. Furthermore, the origin of the scale provided on the outer side of the main branch is the curvature angle, the origin of the scale provided on the outer side of the wife branch is the missing main side, and the length of the missing main side is the nominal diameter of the foundation bolt. Half length. This is because, when the missing wife side is applied to the outer surface of the foundation bolt, the extension line of the outer side of the wife branch coincides with the center of the foundation bolt.
The nominal diameter of the foundation bolt is JIS M8, M10, M12, M16, M20, M24.
, M30, M36, M42, and M48. Nominal diameter M12 is most frequently used as a building foundation bolt, and then nominal diameter M16 is used. Therefore, the length of the missing main side is preferably 6 mm which is half of the nominal diameter M12 or 8 mm which is half of the nominal diameter M16. However, this is not particular.
The scale provided on the outer side of the main branch part and the scale provided on the outer side of the wife branch part may be provided only on one side of the curved scale, but it is preferable that the scale is provided on both sides because it does not need to be turned over.

A curved scale is arranged so that the missing main side is located on the extension line of the inner side of the main branch.
In this way, when the inner side of the main branch is aligned with the side of the base, the origin of the scale on the outer side of the wife branch matches the side of the base. This is because it can be performed accurately.
Moreover, the notch which has the end notch wife side parallel to a wife branch part and the end notch main side parallel to a main branch part is provided in the edge part of a main branch part. Furthermore, the origin of the scale provided on the inner side of the main branch is the end side, the length of the end notched main side is half the nominal diameter of the foundation bolt, and the length of the missing main side and the end notched main side Are different from each other. And about the scale provided in the inner side of the main branch part, you may provide only on the single side | surface of a curved scale, However, It is not necessary to turn the front and back upside down, and it is preferable.
It is preferable to provide it on both the front and back surfaces of the curved scale because there is no need to turn the front and back.
The notch provided at the end of the main branch corresponds to the case where foundation bolts having different nominal diameters are used. For example, when the length of the missing main side is 6 mm which is half of the nominal diameter M12, the length of the end major side is 5 mm which is half of the nominal diameter M10 or 8 mm which is half of the nominal diameter M16. For example, the length of the missing main side and the length of the end missing main side are half the nominal diameters of the different foundation bolts.

As shown in FIG. 1, the curved scale 1 includes a main branch portion 1a and a wife branch portion 1b. The intersection of the outer side 1h of the main branch part 1a and the outer side 1k of the wife branch part 1b is taken as a curve scale angle, and the portion of the curve angle is parallel to the missing wife side 1d parallel to the wife branch part 1b and the main branch part 1a. A notch comprising a notch main side 1e was provided.
Further, the length A of the missing main side 1e was set to 6 mm, and the length was half of the outer diameter of 12 mm of the foundation bolt having the nominal diameter M12. Further, the missing main side 1e is configured to be positioned on an extension line of the inner side 1j of the main branch 1a.
And the scale 1m was provided in the outer side 1h of the main branch part 1a, and the origin of the scale 1m was made into the curvature angle. For this reason, the scale 1 m is a scale lacking the length of A from the origin. Furthermore, a scale 1n is provided on the outer side 1k of the wife branch 1b, and the origin of the scale 1n is defined as a missing main side 1e.
Further, at the portion where the edge 1f of the main branch 1a and the outer edge 1h of the main branch 1a intersect, an end notch main side parallel to the end branch wife 1g and the main branch 1a is parallel to the wife branch 1b. A notch having 1q was provided.
At this time, the length B of the end notch main side 1q was 8 mm, and it was half the outer diameter of the foundation bolt having a nominal diameter M16 of 16 mm. And the scale 1p was provided in the inner side 1j of the main branch part 1a, and the origin of the scale 1p was made into the edge 1f.
Further, any of the scale 1m on the outer side 1h, the scale 1n on the outer side 1k, and the scale 1p on the inner side 1j was provided on both surfaces of the scale 1.

As shown in FIGS. 2 to 4, a large number of foundation bolts 2 b having a nominal diameter 12 protrude upward from the top surface 2 a of the foundation 2. In addition, a black line 2d indicating the position where the base 3 is arranged is marked on the top surface 2a. The side 3b of the base 3 is aligned with the black line 2d, and the base 3 must be installed on the foundation 2.
First, the base 3 is placed on the top surface 2a of the foundation 2, and the base 3 is arranged so that the side surface 3b is parallel to the black line 2d. Then, the measure 1 is placed on the top surface 2a of the foundation 2, and the lacking edge 1d of the measure 1 is applied to the outer surface of the foundation bolt 2b.
The length A of the cut main side 1e of the curved scale 1 is 6 mm, which is half the outer diameter of 12 mm of the foundation bolt having the nominal diameter M12, so that the missing side 1d of the scale 1 is applied to the outer surface of the foundation bolt 2b. The origin of the scale 1m is automatically positioned on the center line of the foundation bolt 2b.
Therefore, by reading the position of the black line 2d using the scale 1m, the bolt center distance D, which is the distance between the center of the foundation bolt 2b and the black line 2d, can be measured.

Subsequently, the end portion 1b of the measure 1 is placed on the upper surface 3a of the base 3, the inner edge 1j of the main branch 1a of the measure 1 is aligned with the side surface 3b of the base 3, and the bolt center distance D is indicated on the scale 1n. Mark ruled lines 3d. Since the origin of the scale 1n is at the missing main side 1e and the missing main side 1e is located on the extension line of the inner side 1j of the main branch 1a, when the inner side 1j of the main branch 1a is aligned with the side surface 3b, the scale 1n Is located on the side surface 3b, and the ruled line 3d corresponding to the bolt center distance D can be accurately marked on the upper surface 3a of the base 3.
Further, in a state where the inner side 1j of the main branch 1a of the curved measure 1 is aligned with the side surface 3b of the base 3, the ditch side 1d of the curved measure 1 is applied to the outer surface of the foundation bolt 2b, and the outer side 1k of the wife branch 1b is contacted. Along the upper surface 3a of the base 3, a ruled line 3e is marked. When the ditch side 1d of the scale 1 is applied to the outer surface of the foundation bolt 2b, the extension line of the outer circumference 1k automatically coincides with the center of the foundation bolt 2b. It is possible to accurately mark the ruled line 3e at the position of the ink line direction bolt.
Then, a hole for a foundation bolt is drilled at the intersection of the ruled line 3d and the ruled line 3e, and the base 3 is placed on the top surface 2a of the foundation 2. By doing so, not only the large number of bolt holes and the foundation bolt 2b all match, but also the side surface 3b of the base 3 matches the black line 2d, so that the base 3 can be installed accurately.

Further, when a foundation bolt 5b having a nominal diameter of 16 is used for a part of the foundation 5, as shown in FIG. 5, the base 3 is placed on the top surface 5a of the foundation 5, and the side surface 3b is placed on the black line 5d. The base 3 is arranged so as to be parallel to the surface. Then, the curved scale 1 is placed on the top surface 5a of the foundation 5, and the end missing wife side 1g of the curved scale 1 is applied to the outer surface of the foundation bolt 5b.
Since the length B of the end notch main side 1q of the curved scale 1 is 8 mm which is a half of the outer diameter 16 mm of the foundation bolt having a nominal diameter 16, the end missing wife side 1g of the scale 1 is placed on the outer surface of the foundation bolt 5b. When applied, the origin of the scale 1p is automatically positioned on the center line of the foundation bolt 5b, and the position of the ink line 5d is read using the scale 1p, so that the distance between the center of the foundation bolt 5b and the ink line 5d is reached. The bolt center distance E, which is the distance, can be measured.
After that, if the measure 1 is placed on the upper surface 3a of the base 3, and the ruled line 3f is marked from the side surface 3b of the base 3 to the position E, the ruled line 3f corresponding to the bolt center distance E is accurately formed on the upper surface 3a of the base 3. Can be marked.
