DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for searching for a leak location in a reinforced concrete building or a wooden building or the like, such as a roof, for finding a leak location in an outer shell for building a house.

[0002]

2. Description of the Related Art As is well known, various waterproofing treatments are applied to a housing construction outer shell such as a roof of a reinforced concrete building or a wooden building so as not to cause a leak or the like.

[0003] As a method of waterproofing, various methods such as sheet waterproofing for laying a waterproof sheet, asphalt waterproofing for laying asphalt, and coating film waterproofing for forming a waterproof coating film have been implemented.

[0004] However, it is impossible to completely prevent rain leakage for many months by any of the methods, and it has been normal for rain leakage to occur over time.

[0005]

In such a case, repairing is performed by searching for a leaking location. However, it has been extremely difficult to specify the leaking location. This is because the rainwater that has penetrated the interior of the building usually sees only the part of the building where the rainwater is exposed on the inside wall of the building. Since it travels along long paths such as inside pillars and walls, it is necessary to follow the trace of this rainwater in order to find places where leaks occur, and especially on rooftops such as concrete buildings. Has a fine uneven surface
However, since it is almost horizontal, it was very difficult to specify the direction of rainwater flow.

[0006] As a result, there have been many cases where the waterproofing work of the building has to be completely redone due to only a few leaks. Therefore, the cost was often extremely large, and the construction period was often long.

As a result of various studies, the inventor of the present invention has found that the electric resistance is low in a portion of a reinforced concrete building or a wooden building or the like where a crack or a pinhole is formed in a housing-forming outer shell such as a roof. It is necessary to discover the fact that the leak has occurred, pay attention to this fact, and use this fact to provide an inexpensive method of searching for a leak location that can very easily find the location of the leak in the outer shell for house composition. Is what you do.

[0008]

In order to achieve the above object, a method for searching for a leak location according to the present invention is provided inside a housing-constituting shell such as a roof in a reinforced concrete building or a wooden building. the leaking wetted zone one of the stationary terminals and stationary connection, the outer side surface of said outer body, the contact state by following the change in shape of the external surface
The brush portion composed of thin metal wires which attained a uniform and Its maintenance
By scanning with the main scanning terminal, the electric resistance between the rain leaking wetted portion and each portion of the outer surface of the outer shell is measured, and the measured resistance value is equal to or less than a preset value. In this case, or when the resistance value is relatively lower than that of the surrounding part, the measurement point in the outer shell is determined to be a rain leak position, and the result is displayed or notified .

[0009]

The leaky wet portion could be on the inner side of such a house construction for enclosures roof in [action] Concrete building or wooden houses, etc., one of the stationary terminals and stationary connection, and changes such as unevenness of the outer body shape the nacelle external surface, said
Uniform contact state following the changed shape of the outer surface
And a brush made of thin metal wire that can maintain the
When scanning with the scanning terminal, the electrical resistance between cracks and pinholes formed in the outer shell forming the flow path of the rainwater to the rain leak wet portion forms a flow path of the rainwater. is lower than the electrical resistance between the other portions do not, low resistance value is obtained, it is classified determine very accurately the other portions not forming the flow path of the such rainwater, leaky
The position can be accurately displayed or notified .

Therefore, depending on the method of forming the housing-constituting outer body, the forming material, and the difference in dimensions and the like,
If the resistance value of the portion forming the flow path is determined by an experiment, the position or location where the resistance value lower than this resistance value is measured can be determined to be the rain leak position.

Further, in the case of the same outer shell for house composition, each of the different resistance values obtained by scanning the other scanning terminal is compared and compared, and the position and the position of the lower resistance value are determined. It can also be determined as a rain leak position.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings illustrating an example of an apparatus for implementing a method of searching for a leak location according to the present invention and several examples of how to implement the method.

First, in FIGS. 1 to 4, reference numeral 1 denotes a main body of a device for searching for a leak location, and the main body 1 has a scanning terminal.
2 is connected to the stationary terminal 3 (see Fig. 5.6)
Ri constitute a seeker position, measures the electrical resistance between the outer side and the inner side of such a house construction for enclosures roof in reinforced concrete buildings or wooden houses, etc., the body
1 itself has a vertically long rectangular parallelepiped shape, the size of which is enough to fit in a breast pocket of a shirt, and is usually waterproof and dustproof, so that it can be used outdoors regardless of the weather.

An analog meter 11 is provided on the upper front part of the main body 1, and the measured resistance value is shown in the meter 11. A determination line 16 is provided on a scale portion of the meter 11. The determination line 16 has a configuration in which the color has changed in the middle, and the possibility that rain has occurred due to the change in the color is displayed. In addition, the determination line 16 is provided according to the type of constituent material of the outer shell for house configuration to be determined, for example, wooden structure, concrete, or the like. The reason for this division is that the resistance value differs depending on the type of the constituent material of the outer shell. The meter 11 is an analog type, but may be a digital type. In this case, impact resistance and the like can be further improved.

A notification lamp 15 is provided at the center of the upper surface of the main body 1. When the measured value of the resistance is equal to or less than a preset value, and is equal to or less than 100 KΩ in the present embodiment, that is, when it is determined that the position is the rain leak position, the notification lamp 15 flashes and the user receives an alarm sound. Is notified. As described later, the preset value is not an absolute value,
More preferably, it can be changed according to the type of house to be determined and the measurement conditions.

Next to the notification lamp 15, a selector 1 is provided.
2 are provided. This selector 12 is for selecting the presence or absence of the above-mentioned alarm sound.

Further, on the right side of the upper surface of the main body , an adjustment knob 17 for performing an adjustment before the measurement is provided.
Thereby, when performing the adjustment, the selector 12
To the position of “ADJ”.

In the lower right part of the upper surface of the main body 1, there are provided a terminal connection portion 13 and a terminal connection portion 14 for connecting the other scanning terminal 2 and one stationary terminal 3 described later. The polarity between the scanning terminal 2 and the stationary terminal 3 does not need to be particularly distinguished, and either may be on the minus side.

[0019] 3, FIG. 5 for embodiment described the use of the search equipment section later. As shown in FIG. 6, one stationary terminal for stationary connection to a wet part formed on the inner side of the house construction outer shell, which has a connection part to the connector part at one end and the other end. The terminal connection part 13 or the terminal connection part 14
It has a long lead portion having a terminal for connection to the body.

Reference numeral 2 denotes the other scanning terminal which is brought into contact with the outer surface of the housing-constituting outer body for scanning.
As shown in FIG. 2, a brush portion 24 made of a thin metal wire 22 is mainly used for uniformizing and maintaining a contact state with an external surface, which is a connecting portion to a connector portion. And a long lead portion 26 having a terminal 28 for connection to the terminal connection portion 14 or the terminal connection portion 13 at the other end.

[0021] FIG. 3 is a block diagram showing an overview of the internal structure of the body 1, in the interior of the body 1, and the resistance measuring circuit 30 and the determination circuit 32, the main part of such an alarm circuit 34 Is arranged.

FIG. 4 shows an example of the resistance measuring circuit 30, and is basically equivalent to a normal resistance measuring circuit.

The determination circuit 32 determines whether or not the resistance value has become a preset value, here 100 kΩ or less.
Reference numeral 4 is for generating an alarm sound and turning on (flashing) the notification lamp 15 when the resistance value is determined by the determination circuit 32 to be 100 kΩ or less.

Next, a method of searching for a leak location in a reinforced concrete building and a wooden building as an example will be described with reference to FIGS.

Even in the case of the reinforced concrete building X as shown in FIG. 5, without using the reinforcing bar 63 incorporated in the concrete 62 which makes the search judgment unstable, the wet portion of the inner lower surface caused by rain leakage is used. One of the stationary terminals 3 is fixed, and the other scanning terminal 2 is externally connected.
When scanning over the waterproof layer 66 forming the side surface ,
In places such as pinholes or cracks points 68 generated in the waterproof layer 66, is detected as a low resistance, it can be determined that the point is causing the leak in the roof.

When rainwater is dripping on the roof from the middle of the inclined part of the roof 70 as in the case of the wooden building Y as shown in FIG. One of the stationary terminals 3 is fixed to the portion, and the waterproof layer 76 forming the outer surface with the other scanning terminal 2.
If you scan the top, the concrete building X shown in FIG.
Similarly to the above, it is possible to determine the rain leak position. In addition,
In the figure, reference numeral 72 is a plywood, 76 is a waterproof layer, and 78 is a crack.

According to the result of the measurement of the resistance by the above-mentioned method, since the structure of an actual house differs for each building, it is not always possible to clearly limit the resistance value using a uniform numerical value. I couldn't do it. However, at least during the measurement of a specific building, there is a clear difference between the state in which the scanning terminal 2 is in contact with the crack or the like causing the leak and the state in which it is not touching. Was done.

[0028] for a house (reinforced concrete, concrete thickness 15cm, seat waterproof + mortar), external
The result of the measurement performed in a state where the side surface is somewhat wet is 2K when the scanning terminal 2 touches the crack.
Ω, to some extent from cracks (1.5m or more)
In a distant place, it was 100 KΩ or more, and a great difference was seen.

[0029] When the scanning terminal 2 is separated from that caused by being cracked portion of the leaking, the resistance value is increased, the external side
In a state where water accumulates on the surface , the resistance value remains small even if it is away from the crack, making the determination difficult. Further, when a material having a certain degree of water absorption such as mortar is laid on the outermost layer, the resistance remains relatively small even when the mortar is away from cracks or the like in a state where the mortar is absorbing moisture. Therefore, determination is leaky has passed some time after the occurrence, outside the house structure for enclosures
It is preferable to perform the process in a state where the part side surface is in a uniform wet state. On the other hand, in the case of a highly water-repellent material such as vinyl chloride, if the accumulated water is removed, the search can be performed immediately.

By the way, when mortar is sprayed on the waterproof layer to perform fire prevention treatment (Note: In Chiba and Saitama prefectures, flammable materials cannot be used for the outermost layer of buildings due to regulations. Is particularly effective because it is difficult to find cracks and the like in appearance. Therefore, repair can be performed only on necessary parts, and the cost and period required for construction can be reduced. In addition, the certainty is remarkably improved.

[0031]

As described above, according to the present invention,
With a very simple method, it is possible to easily and surely find the location or location of a leak in a house or the like. Therefore, it is possible to shorten the time period for repairing the waterproofing, reduce the cost, and improve the reliability of dealing with rain leakage.
