Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a hammer, a load detector provided at the tip of the hammer, and a microphone that detects the sound of hitting a wall tile with the hammer. The present invention relates to a wall tile peeling point marking device for use in a wall tile peeling detection device having a striking portion.

[Prior Art] It is dangerous if tiles, etc. attached to the wall of a building with mortar peel off and fall.
A peeling detection device that detects the state of adhesion of tiles, etc. by the sound of impact was developed by the applicant in Japanese Patent Publication No. 1983-1999.
Publication No. 20498, Special Publication No. 57-23211, Publication No. 1983
-Proposed in Publication No. 1922, etc.

By the way, even if these peeling detection devices detect a peeling location on a wall tile, unless the peeling spot is marked and made visible at the time of detection, the repaired spot, that is, the peeling spot cannot be confirmed at the time of repair.

However, marking the peeled areas with colored paint has the problem of contaminating the wall tiles and spoiling their aesthetic appearance.

In addition, marking defect positions in magnetic flaw detection equipment and ultrasonic flaw detection equipment is disclosed in, for example, Japanese Patent Application Laid-Open No. 139487/1983, but this technique does not allow peeling of wall tiles due to impact sound and its load. It cannot be applied to the level of detection. Furthermore, Japanese Patent Laid-Open No. 59-187206 discloses a technique for marking welded parts of electric resistance welded pipes, but it cannot be applied to wall tiles.

[Problems to be Solved] Therefore, an object of the present invention is to provide a method for removing wall tiles that can detect peeling locations on wall tiles and indicate the inappropriate positions at the same time, thereby making it easier to perform wall tile repair work. To provide a spot marking device.

[Means for Solving the Problems] According to the present invention, a hammer includes a hammer, a load detector provided at the tip of the hammer, and a microphone that detects the sound of hitting a wall tile with the hammer. A pressure tank containing a colorless liquid containing a fluorescent material in the striking part, an electric pump for pressurizing the colorless liquid in the pressure tank; Marking means consisting of a delivery pipe for detecting the colorless liquid from the electric pump and a solenoid valve provided on the delivery pipe is provided, and a load detector is provided at the tip of the hammer, and a marking means is provided to detect the colorless liquid from the electric pump. The present invention includes a peeling determination section that determines peeling of a wall tile based on a signal from the peeling determination section, and a spray control section that sends a valve opening/closing signal to the electromagnetic valve based on a determination result signal from the peeling determination section.

[Description of Effects] Therefore, as in the prior art, the peeling detection device moves along the wall tiles and sequentially hits each wall tile with the hitting section, detects the hitting sound with a microphone, and The load is detected by a load detector, analyzed, and the degree of peeling is determined by a peeling determining section. All of the above belongs to known technology, but according to the present invention, the peeling determination unit sends a determination result signal to the spray control unit, and the spray control unit operates the solenoid valve if repair is required based on the determination result. Open. A colorless liquid fluorescent material is then sprayed onto the area requiring repair.

In this way, the predetermined area (part) of the wall tile
Once the detection is complete, the worker can irradiate the tile with, for example, an ultraviolet lamp attached to a safety rod, visually check the marked area, and repair it.

As described above, according to the present invention, the repair location can be easily indicated without damaging the appearance of the wall surface by spraying the colorless liquid, and the workability of repairing wall tiles can be improved.

[Examples] Examples of the present invention will be described below with reference to the drawings.

FIG. 1 shows a peeling detection device equipped with a marking device suitable for carrying out the method of the present invention.

In FIG. 1, the peeling detection device consists of a striking part 10 that is supported by means not shown so as to be movable vertically and laterally with respect to the wall tile T, and a peeling determining part 20 connected to the striking part 10. Roughly composed.

The striking unit 10 includes a hammer 11 and the hammer 11.
It consists of a load detector 12 provided at the tip of the hammer 11, and a microphone 13 that detects the sound of the impact when the wall tile T is hit with the hammer 11. 20.

Marking means 30, generally indicated by 30, is provided below the hammer 11. The marking means 30 includes a pressure tank 31 containing a colorless liquid containing a fluorescent material, an electric pump 32 that boosts the pressure of the colorless liquid in the pressure tank 31, a delivery pipe 33 that delivers the colorless liquid, and a tip of the delivery pipe 33. It consists of a spray nozzle 34 that sprays a colorless liquid onto the abutting portion between the provided load detector 12 and the wall tile T, and a solenoid valve 35 provided in the middle of the delivery pipe 33. This electromagnetic valve 35 is connected to the peeling determination section 20 via the spray control section 21. In addition, electric pump 3
In place of 2, a compressed gas cylinder may be used in a cartridge type.

During operation, the load detector 12 sends a load, that is, the impact force, and the microphone 13 sends the sound of the impact to the peeling determining section 20 due to the impact operation of the hammer 11 . The peeling determination section 20 determines the size and depth of the peeled portion S from the above-mentioned impact force and impact sound, and sends a determination result signal to the spray control section 21 . The spray control unit 21 sends a valve opening/closing signal to the solenoid valve 35 based on this determination result signal, opens and closes the solenoid valve 35 for a short time, and sprays the colorless liquid from the spray nozzle 34 onto the surface of the wall tile T in the peeled portion S. mark. Since this marking location M is not visible under normal conditions, contamination of the wall tiles is prevented.

During repair, as shown in Figure 2, if the wall tile T is irradiated with an ultraviolet lamp 41 attached to the front of the worker's hard hat 40, the fluorescent material in the colorless liquid at the marking location M will become fluorescent due to the ultraviolet light. Because it emits
The peeled part, that is, the repaired part can be easily visually confirmed.

[Effects of the Invention] As described above, according to the present invention, the following excellent effects are achieved.

(1) The wall tiles to be repaired are marked, so you can immediately see which part of the many tiles should be repaired.

(2) Since a colorless liquid is used, the appearance will not be affected even after a long period of time has passed after detection work.

(3) Repair work can be carried out efficiently, improving work efficiency.
