Description

[Detailed Description of the Invention] The present invention relates to a wall tile peeling detector that detects the adhesion state of tiles, etc. attached to the wall surface of a building with mortar using sound.

It is important to know the state of adhesion of tiles, etc., because accidents often occur where wall tiles, etc. of buildings peel off and fall. For this purpose, in the past, in order to determine the peeling state of wall tiles, etc., a scaffold was set up on the wall to be inspected, and the inspector climbed on the scaffold and struck the wall surface with a hammer or the like to check the adhesion state of the tiles, etc. I was trying to do that. However, not only is it extremely troublesome to set up scaffolding one by one, there are many dangers involved in climbing to high places to work, and individual differences among inspectors make it difficult to obtain accurate data.

Therefore, the applicant first installed a detector equipped with a striking device for striking the wall of a building and a sound receiving device for catching the striking sound generated by striking the wall with the striking device from the rooftop using a wire rope. Peeling detection for wall tiles, etc., which is hung along the wall of a building and transmits the hitting sound captured by a sound receiving device to a hitting sound analysis device installed on the roof to detect peeling locations and conditions of wall tiles, etc. proposed a container (Tokuko Akira)
(See Publication No. 56-20498 and Japanese Patent Publication No. 57-23221).

With this technology, there is no need to set up scaffolding to inspect the adhesion of wall tiles, etc., and there is no danger associated with inspectors climbing to high places to work, and more objective data can be obtained. It will be done. However, since the detector was manually hoisted up and down from the rooftop using a wire rope along the wall of the building, it had the disadvantage that it was not always possible to move the detector up and down smoothly along the wall of the building.

Therefore, the purpose of the present invention is to provide a wall surface that allows the detector to be moved up and down smoothly along the wall surface of a building without requiring human intervention, and that allows for efficient inspection of the peeling state of wall tiles, etc. We provide peeling detectors for tiles, etc.

Figure 1 shows the entire structure of a peeling detector for wall tiles, etc., where 1 is a supporting part, and the supporting part 1 is attached to a building roof A-
Guide wheels 2, . . . , which roll on guide rails laid on guide rails 1, and free sheaves 3A, 3B around which wire ropes, which will be described later, are wrapped are attached. 4
is a striking part, and the striking part 4 includes a striking device 5 for striking the wall surface A-2 of the building;
-2 is provided with a sound receiving device 6 that catches the impact sound generated by hitting the wire rope, and free sheaves 7A, 7B, around which the wire rope is wrapped.
7C, 7D and guide rollers 8, . . . for guiding the wire ropes are attached. For example, as described in Japanese Patent Publication No. 56-20498, the striking device has a striking ball attached to the tip of a rotating lever via a spring, and the rotating lever is rotated by a crank mechanism to strike the wall surface with the striking ball. An ordinary microphone can be used as the sound receiving device. Reference numeral 9 denotes a weight section, and the weight section 9 includes a motor and drive sheave 10 for hoisting the weight section 9 and the striking section 4, a motor and drive sheave 11 for hoisting and lowering the striking section 4, a traction sheave 12,
Free sheaves 13A, 13B, 13C, guide rollers 14, . . . are provided.

The wire rope 1 is constructed by arranging the support part 1 at the top, the striking part 4 at the middle part, and the weight part 9 at the bottom.
5 are multiplied as follows.

One end of the wire rope 15 is connected to a drive sheave 10 that winds up the weight part 9 and the striking part 4,
The wire rope 15 includes the free sheave 3A of the weight section 9, the guide roller 14, the guide rollers 8, 8 of the striking section 4, the free sheave 3A of the supporting section 1, the free sheave 7A, 7B of the striking section 4, and the free sheave of the supporting section 1. Sheave 3B, guide roller 8 of striking section 4,
8. Guide roller 14 of weight section 9, free sheave 13C, traction sheave 12, striking section 4
The drive sheave 11 for hoisting up and lowering the drive sheave 11, the free sheave 13B, the guide roller 14, and the free sheaves 7C and 7D of the striking section 4 are spanned, and the other end is connected 16 to the weight section 9 while being guided.

Therefore, by starting the motor of the drive sheave 10, the weight part 9 and the striking part 4 are simultaneously hoisted up and lowered, and by starting the motor of the drive sheave 11, the striking part 4 is hoisted up and lowered. That is, when the drive sheave 10 is moved, the entire length of the wire rope 15 changes, so the weight part 9 and the striking part 4 move by that amount.
Also, when the drive sheave 11 is moved, the wire rope 1
Since the overall length of 5 does not change, the weight part 9
does not move up and down, but free sheave 1 from connection point 16
Since the length of wire rope up to 3B varies,
The striking part 4 moves. Therefore, in the state shown in the figure, the motor of the drive sheave 11 is started and the drive sheave 1 is
1 to the winding up side or the winding down side, the striking part 4 is moved up and down between the support part 1 and the weight part 9 along the wall surface A-2, and the striking device 5 provided on the striking part 4 is used to move the striking part 4 up and down along the wall surface A-2. -2 is hit, the sound of the impact is captured by the sound receiving device 6, and transmitted to the impact sound analyzer installed on the rooftop to detect the peeling state of the wall tiles, etc. Then, as the work progresses, the detector is moved laterally and the aforementioned operations are performed to detect the state of peeling of the wall tiles.

In the above-mentioned detector, tension is applied to the wire rope by the weight section, and the striking section is pressed against the wall surface by the tension of the wire rope. However, the striking part may sway due to cross winds, etc., and the striking part may not follow the wall surface because the wall surface may be uneven.

Therefore, in order to prevent the striking part from shaking due to crosswinds, etc., and so that the striking part can smoothly follow the wall surface and move up and down even if the wall surface is uneven, the following measures are adopted in the above-mentioned detector in this invention. It has been subjected.

The striking part has an outer frame consisting of a vertical frame member and a horizontal frame member, and the outer frame is supported by a free sheave on which a wire rope is hung and a horizontal shaft, and is made of rubber or synthetic resin that rolls on a wall surface. The inner frame is supported by a horizontal shaft, and is provided with a rolling ring made of rubber or synthetic resin that rolls on the wall surface, and a striking device and a sound receiving device. The inner frame and the outer frame are connected to each other by a pin at the middle, and both ends of the lever are connected to each other by a pin, and the lever has an inner frame that absorbs a reaction force against the outer frame. A spring is provided to press the frame against the wall.

In this way, by providing rolling wheels made of rubber or synthetic resin that are supported by a horizontal shaft and roll on the wall surface on the outer frame of the striking part and the inner frame on which the striking device etc. are installed, cross winds in the striking part can be prevented. Shaking caused by such factors is prevented as much as possible. In addition, the inner frame on which the striking device etc. are installed is supported by the outer frame by a lever connected with a pin, and
Since the outer frame exerts a reaction force and is pressed against the wall surface by the spring, it follows the unevenness of the wall surface well and moves up and down smoothly.
