It was based on the design value on the architectural design drawing and the actual measurement with a scale tape measure at the construction site. In addition, when drilling holes for piping in walls, etc., the marking of the center point was similarly determined by the numerical values on the design drawing and the actual measurement from the base points of the floor, ceiling, walls, columns, etc. of the construction site. .. Especially in the case of a thick wall, since it is necessary to work from both sides of the wall, it is necessary to match the piercing center points on both sides, which requires time and labor for measurement. In addition, when it was difficult to measure, it was unavoidable that the surrounding area was destroyed.

ある。Therefore, there is no problem in a place where actual measurement can be easily and accurately performed at the construction site, but actual measurement cannot be performed unless the object is broken, or the design value and the actual object size are different. , The thickness of the wall is different from the actual thing due to measurement error during actual measurement, the holes drilled from both sides of the wall when drilling for piping are misaligned in the middle of the wall, However, since it was difficult to actually measure, it was unavoidable to destroy the surroundings, which impaired aesthetics and safety. Further, when referring to the design drawing, various problems related to the management of the design drawing such as confirmation of the storage location of the design drawing and taking it out to the construction site have occurred incidentally. The problem to be solved by the present invention is to measure the thickness of walls and floors and to mark the center point of drilling holes for piping when it is difficult to estimate them from the numerical values on the blueprint or measure them at the construction site. It is an object of the present invention to provide an electromagnetic nondestructive inspection and measurement device that enables anyone to make marking of a center point easily, accurately and safely in a shorter time.

る。The electromagnetic non-destructive inspection and measurement apparatus according to the present invention solves the above problems and is as follows. The electromagnetic non-destructive inspection and measurement apparatus according to the present invention comprises a combination of an oscillator (A) that generates an electromagnetic wave and a receiver (B) that receives the electromagnetic wave across an opaque barrier such as a wall or floor. It has a portable shape. For the oscillator (A), either a household AC power source or a dry battery can be selected as a power source, and the oscillation frequency can be selected so as to change the frequency of the electromagnetic wave according to the object to be inspected and measured.
Electromagnetic waves oscillate between two types, strong and weak, cyclically and intermittently. Further, the oscillator (A) has a built-in spirit level (12) for taking horizontal and vertical directions, and a tripod (13) for fixing the position of the oscillator (A) can be attached. The receiver (B) has a dry battery as a power source, receives electromagnetic waves oscillated by the oscillator (A), analyzes the electromagnetic waves with a controller having a microcomputer, and senses the position of the oscillator (A). The receiver (B) receiving the electromagnetic wave from the oscillator (A) is a portion of the direction indicator (1) which is circularly divided and arranged on the receiver (B) depending on its position, and is strongly affected by the electromagnetic wave. Turn on the indicator. When the center line of the oscillator (A) and the center line of the receiver (B) match each other, all of the circular direction display indicators (1) and the ring-shaped matching display indicator ( 2) is lit up together, and the operator is informed that he is ready to mark the drilling position. The operator can then mark the matching points using the marking holes (3). Also, when the oscillator (A) and the receiver (B) are aligned with each other and the coincident display is made, the memory button (4) on the receiver (B) is pressed to reduce the thickness of the wall, floor, etc. at that time. Three
It is displayed on the digit wall thickness gauge (8) and is stored and stored in the controller. Also, the average value button (5)
By pressing, the average value of the wall thickness values previously stored in the controller is displayed on the 3-digit digital wall thickness gauge (8). The three-digit digital wall thickness meter (8) is displayed by the wall thickness value lamp (6) and the average value lamp (7).
