Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a building measuring instrument for measuring the vertical, horizontal and inclination of columns, beams and roofs.

[0002]

[Prior art]

 As a conventional measuring instrument for construction of this kind, for example, in Japanese Utility Model Publication No. 57-49768, column 2, lines 18 to 22, a weight is struck with a batting plate by turning a handle against a wall. A vertical device has been proposed that measures the verticality of a wall, etc., depending on whether the weight reaches the center point or whether the hanging thread overlaps the vertical line. However, in the case where the weight is hung at the lower end of the hanging thread in this way, it takes time until the runout of the thread stops completely, and it is difficult to measure accurately due to the runout of the weight. .

Therefore, in Japanese Utility Model Laid-Open No. 2-75512, a lower part of a thread is fixed to a center point of a bottom of a transparent tubular container body, and a float is tied to an upper part of the thread to keep water in the container tube body. A vertical device applying buoyancy is proposed, which is based on the fact that the yarn floated by buoyancy and the float become physically vertical with the center point as the axis, and a glass window is provided on the side of the tube. At the same time, the glass window is provided with a center line, and the vertical state can be measured by the overlap between the center line and the yarn.

[0004]

[Problems to be solved by the device]

 Since the vertical device utilizes the buoyancy of the float, the yarn swings less than that using the weight, and the vertical can be accurately determined in a short time. However, since the vertical state is measured by the overlap between the center line provided in the glass window and the thread, there is a concern that an error may occur depending on the line-of-sight direction and accurate measurement may not be possible. Moreover, since the vertical instrument is used only for vertical measurement, it cannot be used for horizontal or tilt measurement.

Therefore, the first object of the present invention is to provide a construction measuring instrument capable of accurately and easily measuring horizontal and inclination, and secondly, accurately and easily measuring horizontal and vertical and inclination. It is an object of the present invention to provide an architectural measuring instrument that can be easily measured.
