Abstract

(57) [Summary] [PROBLEMS] In a damage monitoring method that monitors pressure drop by applying pressure to a hot water pipe of a hot water panel, damage may not be reliably detected, and water leakage may occur later. . And if the damage cannot be detected during construction,
The cost and labor required for repairing after the damage has been found will be enormous. A hot water pipe made of resin having a conductive layer formed on an outer periphery thereof is disposed in a panel body, and a conductive layer is laminated on an upper surface to form a hot water panel for floor heating. When the floor panel 11 is installed on the floor, a detection device 10 is connected to the respective conductive layers via the detection wires 7 (7a, 7b), and a change in resistance between the conductive layers is monitored.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for monitoring damage to a hot water panel for floor heating.

[0002]

2. Description of the Related Art A floor heating panel is provided with a floor panel on the upper side of a panel body provided with a resin hot water pipe to measure heating from the floor panel. It is fixed with nails on the upper side of the main body.

[0003] In the construction of such floorboards, care is taken to prevent nails from piercing the hot water pipe. However, there are cases where nails are accidentally pierced, and if this is not noticed, water leakage will occur.

Therefore, conventionally, a water pressure is applied to the hot water pipe during construction of the floorboard, and a change in the pressure is monitored, and when the pressure value decreases, damage to the hot water pipe is determined.

[0005]

However, even if the hot water pipe made of resin is damaged by a nail, it may adhere to the nail and may not leak water at the time of inspection. In this case, the pressure does not decrease, so that the pipe is damaged. Cannot be detected.

[0006] Even if water does not leak at the time of inspection as described above, water leaks during use due to expansion, contraction, vibration, and the like due to temperature, and at this time, damage to the hot water pipe is known only at this time.

If the damage cannot be detected at the time of construction as described above, the cost required for repair after the damage is found,
It takes a lot of time.

[0008] On the other hand, as another damage detection method, a conductive layer is laminated on the upper surface side of the panel body, and when the nail penetrates through the conductive layer into the hot water panel, the conductive layer and the electrode in place are placed. There is an attempt to detect the damage by detecting the resistance of the water in the hot water pipe existing in the water, but in this method, the damage is detected by energizing through the water, so reliable detection due to the high resistance of the water There is a problem that it is relatively difficult and that water must be poured into the hot water pipe during construction of the floorboard. An object of the present invention is to solve such a problem.

[0009]

In order to solve the above-mentioned problems, according to the present invention, first, a resin hot water pipe having a conductive layer formed on the outer periphery is provided in a panel body, and a conductive layer is formed on an upper surface side. Laminate to form a floor heating hot water panel, and when installing a floor panel on the upper side, connect a detection device to each of the conductive layers via a detection wire, and monitor a change in resistance between the conductive layers. We propose a method for monitoring the damage of the configured hot water panel for floor heating.

According to the present invention, in the above configuration, the locations of the hot water panel for connecting the detection wires to the respective conductive layers are on the indoor wall side, and the detection wires connected to these portions are passed through the wall. It is proposed to extend to the outside such as a room and connect to a detection device installed in a room or the like.

According to the present invention, the nail having damaged the hot water pipe penetrates the conductive layer on the upper surface of the panel body and the conductive layer on the outer circumference of the hot water pipe at the same time. , Is significantly reduced as compared with the normal state, so that damage can be easily and reliably detected. Also, there is no need to put water as a current-carrying medium into the hot water pipe.

Further, according to the present invention, the detection device can be installed outside the room or the like via the detection wire passing through the inside of the wall, and the monitoring of the damage can be continued even after the floor panel is constructed.

[0013]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory longitudinal sectional view showing an embodiment of the present invention, FIG. 2 is a perspective view of a hot water pipe to which the present invention is applied, and FIG. It is. In these figures, reference numeral 1 denotes a floor heating hot water panel. The floor heating hot water panel 1 has a resin hot water pipe 2 disposed in a panel body 3 and a conductive layer made of aluminum or the like on the upper surface side. 4 are stacked. Further, a conductive layer 5 of aluminum or the like is also formed on the outer periphery of the hot water pipe 2.

The hot water pipe 2 has a header portion 6 on the wall side of the panel body 3. In the header portion 6, a detection wire 7 a is connected to the conductive layer 5, and the detection wire 7 a is detected near the conductive layer 5. Cable 7b is connected. These electric wires 7 (7 a, 7 b) pass through the wall 8 and reach the room. It can be extended from the inside of the wall 8 to the room through an appropriately configured opening 9 or the like. The detection device 10 is connected indoors. In addition, the detection device 10 can be installed not in a room but in a suitable place outside a wall.

In the above configuration, when the flooring material 11 is to be installed as a floor plate above the hot water panel 1 for floor heating, the detection device 10 is connected to the indoor side of the detection wire 7 and the switch is turned on to perform monitoring. start. Hot water pipe 2
There is no need to fill the water inside.

In the construction, if the hot water pipe 2 is not damaged by the nail 12 for fixing the flooring material 11, the conductive layers 4, 5 to which the detection electric wire 7 is connected are connected.
The resistance between them is virtually infinite. On the other hand, nail 1
When 2 is inserted into the hot water pipe 2, the conductive layers 4 and 5 are brought into conduction through the nail 12, so that the resistance value is greatly reduced. Accordingly, the detecting device 10 issues a warning by detecting a large change in the resistance, that is, a decrease in the resistance. Therefore, the floor panel installer can detect the damage of the hot water pipe 2 by the alarm of the detection device 10.

Since the detection device 10 only needs to detect such a large change in resistance, a detection circuit can be configured very easily.

As described above, according to the present invention, when the hot water pipe 2 is damaged by the nail 12, it can be detected immediately at the time of construction, so that repair is easy and the cost is small.

[0019]

As described above, the present invention has the following effects. a. Damage is detected by a large decrease in resistance, so that a simple detection device can reliably detect damage. b. There is no need to fill the hot water pipe. c. The detection device can be installed outside the room or the like via the detection wire passing through the wall, and the monitoring of the damage can be continued even after the floor panel is installed.
