Abstract

(57) [Summary] [Purpose] To provide a steel frame building measuring instrument which can efficiently measure the length of columns and beams by itself in a steel frame building. The present invention is characterized in that a plate-shaped magnet 3 is provided between an iron plate 1 and an iron plate 2 having the same shape as the iron plate 1.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 This invention relates to an auxiliary instrument for measuring steel-framed buildings that is used in construction work, especially when measuring the horizontal and vertical lengths of columns and beams of steel-framed buildings. .

[0002]

[Prior art]

 Conventionally, in construction work, especially when measuring the horizontal and vertical lengths of columns and beams in steel structures, one person has the tip of the tape measure and another person reads the scale on the tape measure. Since at least two people are needed, when measuring alone, measurements were taken from a place where the metal fitting at the tip of the tape measure could be hooked.

[0003]

[Problems to be solved by the invention]

 However, there were the following disadvantages. (B) The pillars of steel-framed buildings, especially square steel pipe columns for building structures, have a quarter circle shape, so the claw at the end of the tape measure cannot be caught and the length in the horizontal direction It was difficult to match the tip with the outer surface of the pillar when measuring the value. (B) When measuring the vertical length of pillars of a steel-framed building, it was difficult to measure accurately because there was nothing to fix the nail at the tip of the tape measure in a state suitable for measurement. The present invention has been made to eliminate these disadvantages.

[0004]

[Means for Solving the Problems]

 A plate-shaped magnet 3 is provided between an iron plate 1 and an iron plate 2 having the same shape as the iron plate 1. The present invention is a measuring instrument for a steel-frame building having the following configuration.

[0005]

[Action]

 A plate-shaped magnet 3 is provided between an iron plate 1 and an iron plate 2 having the same shape as the iron plate 1. Then, the small part is fixed to columns and beams of a steel-framed building.

[0006]

【Example】

 Hereinafter, embodiments of the present invention will be described. A plurality of plate-shaped magnets 3 are provided between an iron plate 1 having a crank-shaped notch in a corner and a graduation and an iron plate 2 having the same shape as the iron plate 1. This project has the above structure, and when this is used, the fore-edge is fixed to the corners of columns and beams of a steel-framed building. Then, hook the metal fitting at the tip of the tape measure to the notch of the entrance and measure the length. Also, fix it to a pillar of a steel-framed building as shown in Fig. 4, scratch the metal fitting at the tip of the tape measure, and measure the length.

[0007]

[Effect of the invention]

 Conventionally, measurement tasks that required at least two people can now be performed by one person. In addition, the length can be measured even if there is an obstacle by fixing to the pillars and beams at both ends of the steel-framed building, and adjusting the scale to stretch the thread. This allows more efficient measurement than before.
