Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and an inspection device for inspecting the condition of iron reinforcement before concrete is poured.

Since the reinforcing bars play an important role in maintaining strength, it is necessary to inspect whether the reinforcing bars are installed according to the design drawings. Conventionally, this inspection was carried out by two people. : They were done one by one. In other words, inspection of the reinforcement arrangement status involves checking whether the thickness, spacing, number of reinforcing bars, etc. of the reinforcing bars match the drawings. Conventionally, this inspection was done manually, so inspection There are disadvantages in that it takes a long time to inspect reinforcing bars in narrow areas where people cannot get close to them, and some kind of countermeasure has been desired.

The present invention has been made in view of the above-mentioned circumstances.The purpose of the present invention is to provide a method for easily inspecting the reinforcement condition in a short period of time.
Is Rukoto. According to the present invention, the optical sensor is scanned in a direction across the reinforcing bars, and the signals are processed by a combi coater, thereby achieving the above object.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Now, referring to FIG. 1, the inspection apparatus according to the present invention consists of a measuring section 1 and a control box 20.

The control box 20 has a built-in micro combicoater and has a calculation function.Therefore, the keyboard 21 can be scanned to select the necessary items for the area to be inspected.
For example, the height of reinforcing bars, the spacing of reinforcing bars, the number of reinforcing bars arranged at predetermined intervals, etc. are inputted, and when the measured signal is applied, these inputs are compared with the set values, and calculations are made. The binding is displayed on the display device 22 and printed 1 to 23 so that the reinforcing condition can be inspected.

In addition, Controller 1 to Rollbox have a built-in storage battery,
It is convenient to use something that can be used as a power source for microcomputers, display devices, printers, etc.

The measuring section 1 has a scanning scale 2, which is box-shaped and arranged in the measuring section in a direction across a large number of reinforcing bars. A feeder 3 is provided inside the scale 2 to reciprocate the optical sensor 4. and,
It consists of a motor 7 that rotationally drives this screw, and rod-shaped guide shirts 1 to 8.8 arranged on both sides of the screw 6. And the feed screw 6 is a lazen double screw 9.
．． 9- is formed, and the base 10 of the optical sensor 4, which is 3 to the 1st power, is screwed onto this screw.

The pitch of the 5-len double screws, 9', is larger on one side than the other ('1), so that the scanning speed can be changed, thus increasing the return speed and increasing the inspection efficiency. [Note] ζ A・71-8.8 is the feed screw 6.
When the base 10 is rotated and the base 10 reciprocates to the left or right, the base force (prevents it from rotating) is used.Alternative current power may be used as the power for the motor 7. Car A, a storage battery is built into space 1-2, and it is connected to ear 1.
You may use a river, or you may use a condenser in the controller 1 to roll box.

The optical sensor 4 is installed on a base 10 and reciprocates within the scale. Further, the slit force X formed on the bottom surface of the scale 2 protrudes from the tip 1. The light-γ sensor 4, the encoder 11 (, and the horizontal line 12)
Also, what is the encoder 11 and the control box 20?]
The bottom 81S of the scanning scale 2 is fitted with a twisting cushion '14. ironfl'
-C begins to soften the impact when it comes into contact with +'+.

Fixed to 11.

Next, the inspection method according to the present invention will be explained.

First, the scanning scale 2 is installed in a direction that crosses a large number of reinforcing bars f at the measuring section. Then press STAR 1- and IN button 16. Then, the motor 7 is started, and the base and hence the optical sensor 4 are scanned in a direction across each reinforcing bar f by the feeding device. Then, during this scanning (necessary items such as the thickness of the reinforcing bars, the spacing D of reinforcing bars, the number of reinforcing bars arranged at predetermined intervals, etc.) are measured.Then, this measured value is converted into a signal by the J recorder 11, The input voltage is applied to the computer at 20: 1"15. The computer inputs the required items of the area to be inspected, such as the thickness, spacing, and number of reinforcing bars, which are specified in advance on the design drawing, to the keyboard 21. Therefore, the measured signal is compared with this set value and the result is automatically displayed on the display device 22, and if necessary, the signal is
~ will be done.

As explained above, in the present invention, the reinforcing bars to be inspected are scanned by an optical sensor, and the measurement signal is processed by a microcomputer and displayed or printed. In addition to being able to perform inspections quickly, it also has the advantage of being able to inspect the condition of reinforcing bars in narrow areas where people cannot get close to them.
