Description

[Detailed Description of the Invention] The present invention relates to a peeling detector for wall tiles, etc., which uses acoustic waves to detect peeling locations of tiles, etc. attached to the walls of buildings with mortar, and the state of their adhesion. The present invention relates to a peeling detector for wall tiles, etc., which allows the detector to be smoothly raised and lowered along the wall of a building.

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,
Conventionally, in order to determine the peeling state of wall tiles, etc., a scaffold was set up on the wall to be inspected, and an inspector climbed on the scaffold and struck the wall surface with a hammer or the like to inspect the adhesion state of the tiles, etc. Ta. However, not only is it extremely troublesome to set up scaffolding one by one, but climbing to high places is often dangerous, and there are individual differences among inspectors, making it difficult to obtain accurate data.

Therefore, the applicant first installed a detector from the rooftop using a wire rope, which was equipped with a striking device that struck the wall of the building and a sound receiving device that caught the sound of the striking caused by striking the wall with the striking device. A peeling detector for wall tiles, etc., which is hung along the wall of a building and detects the peeling location and condition of the wall tiles by transmitting the hitting sound captured by a sound receiving device to a hitting sound analyzer installed on the roof. proposed (Tokuko 1984-
(See Publication No. 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, the detector was suspended from the rooftop with a wire rope.
Since the detector had to be hung down manually along the wall of the building, it had the disadvantage that it was not always possible to move the detector smoothly along the wall of the building.

Therefore, an object of the present invention is to provide a wall tile that allows a detector to be raised and lowered along the wall of a building without requiring any human intervention, and that enables efficient inspection of the peeling state of wall tiles, etc. etc. to provide peeling detectors.

Therefore, according to the present invention, there is provided a supporting part in which two free sheaves are provided spaced apart in the horizontal direction and supported on the roof of a building, a striking device for striking the wall surface of the building, and a striking device for striking the wall surface. A striking section is provided with a sound receiving device that catches the striking sound generated by striking the hammer, and is provided with two free sheaves on the upper and lower sides spaced apart in the horizontal direction, and a striking section that winds up the weight. a first motor and a first drive sheave driven by the first motor; a second motor that winds up and lowers the striking part; and a second drive sheave driven by the second motor;
It has a free sheave provided horizontally apart from the first drive sheave, and a weight portion provided with free sheaves provided horizontally apart from each other on both sides of the second drive sheave,

Free sheave provided at different intervals, free sheave on one side of the support part, free sheave on one side of the upper part of the striking part, free sheave on the other side of the upper part of the striking part, free sheave on the other side of the support part, weight part A free sheave on one side provided horizontally apart from the second driving sheave, a second driving sheave, a free sheave on the other side provided horizontally apart from the second driving sheave, and a striking A peeling detector, such as a wall tile, is provided, which is connected to a free sheave on one side of the lower part of the part and a free sheave on the other side of the lower part of the striking part, and the other end is connected to the weight part.

As a result, the detector can be installed and the striking part can be moved vertically along the wall surface without requiring any human power, and peeling of wall tiles, etc. can be efficiently inspected. Further, a motor for hoisting the weight part and a motor for hoisting up and lowering the striking part are attached to the weight part, and the load of the weight part applies tension to the wire rope, so that swinging of the striking part is prevented as much as possible.

In implementation, it is necessary to fix the center of gravity so that the striking part and the weight part move horizontally, and the weight part of the winch part hoisting motor and its drive sheave, whose weight changes depending on the amount of wire rope taken up, must be fixed.

7 and 15 are guide rollers for the wire rope 16 provided in the striking part 4 and the weight part 8. Although not shown, a safety device such as a governor to prevent falling is provided.

Next, the work procedure will be explained. It is assumed that the support part 1, the striking part 4, and the weight part 8 are stacked and the wire rope 16 is wrapped around them in the above-described manner. Preparation is completed by setting this detector on the hanger of the hanging device installed on the rooftop A-1. When the preparations are complete, rotate the weight hoisting motor 9 and remove the wire rope 1.
6, the striking part 4 and the weight part 8 rise together, and when there are no restrictions on the lower part of the building, the motor 9 stops slightly above the ground, and it cannot be installed near the ground. When the motor 9 is raised to the required height, the motor 9 is stopped. Figure 1 shows the situation.

In the state shown in FIG. 1, the striking part hoisting and lowering motor 11 is operated to move the striking part 4 up and down between the support part 1 and the weight part 8. that time,
A striking device installed in the striking unit 4 hits the wall A-2, and the sound of the impact is caught by a sound receiver and transmitted to a hitting analyzer installed on the roof, thereby determining the peeling state of the wall tiles, etc. on the wall A-2. To detect.

The work is carried out one by one by moving the detector in the horizontal direction of the arrow, but if there is an obstacle such as a protrusion on wall A-2 and the detector cannot pass, the weight part hoisting The motor 9 is operated to wind up the weight part 8 and the striking part 4, and the detector is moved horizontally to avoid obstacles. Then, the peeling state of the wall tiles, etc. is inspected in the manner described above. When the inspection work for the entire wall surface is completed, the weight part hoisting motor 9 is operated to lower the striking part 4 and the weight part 8 to the ground and remove the detector.

As explained above, according to the present invention, the detector can be installed and the striking part can be moved vertically along the wall surface without requiring human power, and peeling of wall tiles, etc. can be efficiently inspected. . Further, since a motor for hoisting the weight part and a motor for hoisting and lowering the striking part are attached to the weight part, and tension is applied to the wire rope by the load of the weight part, swinging of the striking part is prevented as much as possible.

When carrying out the operation, it is necessary to fix the center of gravity so that the striking part and the weight part move horizontally, and the weight part hoisting motor and its drive sheave, whose weight changes depending on the amount of wire rope taken up, must be fixed at the weight part. Place it on the center of gravity. In addition, a braking force is applied to the wire rope provided with a traction sheave in the striking part and the weight part to prevent the wire rope from slipping and to prevent inertia from acting on the drive.
