Description

  In the present invention, when scoring material attachment locations and drilling locations on steel materials of various structures such as bridges, elevated road girders, buildings and other existing steel structures, The present invention relates to a scoring template (measuring tool for scoring) that can be used for measuring and positioning.

  When remodeling (improving) existing steel structures as described above and attaching members, work for scoring the steel material (scribing work) is performed. Conventionally, a ruled part is determined by using a deposit, a swing-down, a water thread, and the like, and a ruled tool is used to mark the part. When the flange of the spar and the web are welded, it is necessary to avoid (by avoid) the fillet weld bead (welding bead) and determine the scribe position in order to scribe the spar web.

  Conventionally, in order to position a creased portion, two inserts are stacked and combined, and a right angle and a parallel are scribed. Alternatively, when measuring, instead of directly, the auxiliary line (fleece ink) was drawn once at the position where the bead was dodged, and the measurement was made using that. As the ruler, there are those shown in Patent Documents 1 to 3.

Japanese Patent Application Laid-Open No. 08-101001 JP 2006-159212 A JP 2014-227653 A

  When aligning the right and parallel lines with two inserts combined for positioning the marking area, it was not easy to use unless skillful. The ruler shown in Patent Document 1 has a recess for escaping the weld bead, but is difficult to use because it is a combination of two measurement gauges. In Patent Documents 2 and 3, there is a problem that it is difficult to use in a place where there is a weld bead because there is no escape of the weld bead, or it is difficult to measure an accurate scoring position because the weld bead becomes an obstacle.

  The problem to be solved by the present invention is that even a steel material having a weld bead can be accurately measured and positioned by avoiding the weld bead, and is easy to use. The object of the present invention is to provide a ruler measuring instrument that is convenient to carry with a size (pocket size) that can be accommodated in a pocket.

  The scribing measuring tool of the present invention has a relief portion at one or more corners of four corners (squares) of the rectangular substrate, and the relief portion is one of two sides sandwiching the relief portion of the rectangular substrate. If the side of the member is addressed to the member to be marked, and the other side is assigned to another member in the direction perpendicular to the member to be scored, it is an inclined surface or curved surface at an angle that can avoid the weld bead of both members. . In the ruler of the present invention, the length scale and the length value are displayed on both or either of the two sides sandwiching the relief portion. The length scale and the numerical value of the length are displayed starting from the intersection of virtual lines extending two sides sandwiching the relief portion. When the relief portion is formed at two or more corners of the rectangular substrate, the shape and size of the relief portion may be the same or different. When the escape portion is a slope, the slope angle and the slope length can be the same or different. When the escape portion is a curved surface, the curved surface (the radius of the arc) may be the same or different. The size of the relief portion is determined because it does not interfere with the weld bead.

  Several crack measurement lines with different thicknesses can be displayed on the sides other than the side on which the length scale is displayed. A line width value indicating the thickness of the crack measurement line is displayed near the crack measurement line. The crack measurement line can measure the width of the crack by addressing the crack that has entered the steel material. Of course, this crack measurement line can also measure the width of cracks in concrete.

  A circular scale and a numerical value of the hole diameter can be displayed on the square substrate. Two or more circular scales can be displayed concentrically. It is also possible to display several angle lines and angle numerical values extending radially from the scales at arbitrary locations in the circumferential direction of these circular scales. The angle line can be displayed up to the side of the extension line.

  The square substrate may be opaque, but it should be transparent or semi-transparent, and the square scale, crack measurement line, length value, line width value, etc. displayed on both sides of the square substrate should be square. It is convenient to be able to read from either the front or back side of the substrate.

  The length scale is displayed with the starting point reversed on the front and back sides of one side of the square substrate, and the length value is displayed on the top and bottom two lines near the length scale. Even if it is displayed upside down and the rectangular substrate is turned upside down and addressed to the measuring unit or used, the length value can be confirmed in the normal direction. The length values of the two lines can be displayed in different colors to make it easy to distinguish the length values of the respective lines. The scale can also be displayed in inches or radians.

  A reference line perpendicular to the cross is displayed on the rectangular substrate, and a cut or a hole is made in the middle or on an extension line of the cross-shaped reference line, and a pen is applied to the cut or the hole along the reference line. It is also possible to draw a cross line by displaying marks in four directions and connecting the opposite marks together to draw a straight line. In addition, a center scoring hole for scoring the center of the shaft end of the existing bolt can be opened at the center of the circular scale displayed on the center side of the rectangular substrate.

The ruler measuring instrument of the present invention has the following effects.
(1) Since the weld bead can be avoided at the escape portion, one side is addressed to the member to be scored, the other side is addressed to the member to be scored and the other member orthogonal to the scored position. Accurate measurement is possible.
(2) Since the length scale and the length numerical value are displayed on both or one of the two sides sandwiching the relief portion, it is possible to easily measure the size of the ruled part.
(3) Since the measurement scale is displayed with the intersection of two sides sandwiching the escape portion as a starting point, highly accurate measurement can be performed even if the weld bead is avoided at the escape portion.
(4) When the crack measurement line and the line width numerical value are displayed, the crack measurement line can be assigned to the crack so that the width of the crack can be easily confirmed, and the crack width can be read with the line width numerical value. it can.
(5) By displaying a circular scale, it is possible to easily measure the hole diameter by reaching a bolt insertion hole or other hole opened in the steel material.
(6) By displaying several angle lines that extend radially outside the circular scale at several locations in the circumferential direction of the circular scale, cross marks are made on the steel material, and angle measurement is performed. be able to.
(7) When the rectangular substrate is made transparent or translucent, the length value, the line width value, etc. can be read from both the front and back surfaces of the rectangular substrate, which is convenient.
(8) When the length value is displayed in two lines up and down from the starting point in the opposite direction, and the length value of two lines is displayed in the upside down direction, the rectangular substrate is turned upside down and directed to the steel material. However, since any one of the numerical values in the two rows is in a normal direction, it is difficult for the numerical value to be misread.
(9) When a reference line orthogonal to the cross is displayed on the rectangular substrate, the cross line can be easily marked along the reference line.
(10) If a cut or hole is made in the middle of the reference line of the rectangular substrate or on an extension line, a mark can be displayed with a pen at the position of the cut or hole, and the cross marks are drawn by connecting the opposite marks. Can be easily marked.
(11) In the case where the center marking hole is provided in the rectangular substrate, the center position of the shaft end of the existing bolt can be easily marked, and the interval between two or more existing bolts can be measured.
