Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a water leak investigation method capable of specifying a point of this water leak when a water leak occurs from a part of the hot water piping for heat dissipation in the hot water type floor heating facility. In addition to investigating the location of water leaks due to nailing during floor heating construction, for example, when water leakage occurs after renovation, for example, during renovation, this water leak location (nailing location) is a point. The present invention relates to a method for investigating water leaks, which can be specified and can specify all of the plurality of water leak points by points when water leaks occur at a plurality of points.
[0002]
[Prior art]
In the hot water type floor heating equipment, a mat having a heat-dissipating hot water pipe is laid on a base material or a slab, and the floor material is constructed thereon. For example, FIG. 4 shows an example of a hot water mat that is a hot water type floor heating system for general households. In FIG. 4, a hot water mat 1 is made by inserting wooden small joists 3 alternately from the opposite side to a mat main body 2 made of foamed polyethylene (or foamed polystyrene) at regular intervals to form a crosslinked polyethylene pipe (heat radiation tube) 4. Is constituted by meandering piping so as to bypass the tip of the small joist 3.
[0003]
When the hot water mat 1 is constructed, as shown in FIG. 5 (A), the hot water mat 1 is laid on the base plywood 5, and the flooring material 6 is laid on the mat, and the joint of the flooring material 6 is formed. The screw nail 7 is struck at an angle of about 45 ° so as to reach the small joists 3 and the base plywood 5. In FIG. 5A, 8 is a heat insulating material, 9 is a dummy plywood, 10 is a heat shield tube, 11 is a system controller, 12 is a hot water pipe, and this point is connected to a heat source machine. As an example of construction of the hot water mat 1, as shown in FIG. 5B, the hot water mat 1 is directly laid on the slab 13, and the floor material 6 is stretched directly on the hot water mat 1. There is also a construction method called sticking.
[0004]
Thus, when flooring is performed in a floor heating facility, a large number of screw nails 7 are used and the screw nails 7 are to be struck at an angle of about 45 °. If the angle is distorted, a nail tip may be struck on the cross-linked polyethylene tube 4. Such a problem may also occur in the direct pasting method shown in FIG.
Although the above is a problem at the time of construction, when the nail is used after changing the partition, repairing the floor noise, etc., this nail is struck against the crosslinked polyethylene pipe 4, and water leaks from here. There are many cases. The cause is
1) Insufficient meeting with the construction side.
2) Insufficient confirmation of ink marking position.
3) Construction mistake on the construction side.
Etc.
[0005]
In order to prevent the occurrence of such a water leakage accident, it is necessary to arrange the position of the hot water mat 1 and the position of the small joist 3 and the cross-linked polyethylene pipe 4 in advance. Meetings are possible at the time of construction, but in the case of renovation after moving in (partition change, etc.) or repairing floor noise, sufficient meetings are not possible. For this reason, there are many complaints of water leakage especially after moving in.
[0006]
Conventionally, if there is a complaint of such a water leak,
1) Perform a water pressure test (pressurization of 0.2 to 0.3 MPa, check with a water pressure gauge after 30 minutes)
2) Use a stethoscope to listen and confirm the sound of the balloon,
3) The heat source is operated by thermography, and the water leakage is investigated by checking the temperature distribution (difference) on the floor surface.
[0007]
However, the above three investigation methods have the following drawbacks.
1) I know the system of the hydraulic gauge / mat, but I don't know where the water leaks.
・ I do not know the water leakage in multiple places.
2) It is difficult to distinguish between the target sound and noise in the vicinity of sound / roadway, in a noisy place, a property under construction, or a property that has already been moved in.
・ Water leakage at multiple locations is difficult to understand.
3) I don't know the point of thermography / water leak.
・ If the amount is small, it is difficult to confirm changes in temperature distribution.
・ I do not know the water leakage in multiple places.
[0008]
As mentioned above, in the conventional water leak investigation method, there is no definitive method, especially because the point of nailing cannot be specified by point, try to peel off the flooring material with an approximate register, There are many problems that the parts will be peeled off, and that it is expensive to find the leaked parts and to repair the labor, time and cost. In particular, when there are water leaks at multiple locations, it is difficult to find all of these multiple locations with a single survey, so it is necessary to re-examine and repair after repairing the first water leak location There is also.
[0009]
[Problems to be solved by the invention]
An object of the present invention is to provide a water leak investigation method capable of reliably finding a water leak point at a point in a hot water type floor heating facility, and also reliably finding water leaks at a plurality of points. Is to provide.
[0010]

All locations are characterized as being water leak locations.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
In warm water type floor heating equipment, a typical example of what is used as a flooring is flooring, but in the case of cork, vinyl chloride sheet, tatami mat, carpet finish etc., nails are not used at the time of construction, so there is a concern about water leakage Absent. However, after moving in, for example, when partitioning is performed during renovation, if a nail is used to fix the partition, water leakage may occur due to this nail driving. It can also be used for occasional surveys.
When investigating a water leak location, the location where floor heating equipment is installed in the room is specified using a drawing or a box attacker.
[0013]
Next, while placing the nail positioning magnet on the floor, positioning is performed for all the nails, and markings such as ◯ are performed.
Next, connect the ground to the MΩ meter. If there is a ground terminal (outlet) in the room, this ground is connected to this, and if not, the ground wire is extended to the ground for grounding.
Next, the sensor is sequentially applied to the locations marked earlier, the insulation resistance value is read from the pointer of the MΩ meter, and a mark such as x is further marked at a location where the insulation resistance value is particularly low. In this way, the insulation resistance value is measured for all the marked portions.
[0014]
FIG. 1 is a graph showing the data measured in this manner. Nails are struck at 15 locations, and Nos. 1 to 15 are given. Among these Nos, the insulation resistance value is greatly reduced from the reference level at two locations of the number 4 and the number 12.
In the determination, these two locations are identified as the water leak locations.
In the place specified as the water leaking place, the flooring material is first peeled off and visually inspected. If there is no mistake, the hot water mat is replaced with a new one in principle.
[0015]
【Example】
FIG. 2 shows a state in which a water leak investigation is performed, in which 20 is an MΩ meter (insulation resistance meter), 21 is a ground wire, and the ground is grounded. Reference numeral 22 denotes a sensor of the MΩ meter 20, and the worker 23 investigates the water leaking portion 24 using the sensor 22.
In FIG. 2, 1 is a hot water mat, 5 is a base plywood, and 6 is a flooring material.
FIG. 3 shows a flow of water leakage investigation. Based on this flow, a specific investigation method (procedure) will be described next.
[0016]
1) First, using a drawing or a box attacker (metal detector), the hot water mat 1 is positioned from the aluminum sheet affixed to the surface of the hot water mat 1 (step 1).
2) The nail is positioned with the nail positioning magnet (step 2).
3) If the hot water mat 1 leaking water can be operated, it is operated for about 10 minutes. If operation is not possible, maintain a water pressure of about 0.2 to 0.3 Mpa with a water pressure tester for about 10 minutes (this is not the case if it is immediately after reporting a water leak) (Step 3).
4) The ground wire 21 of the MΩ meter 20 is connected to the ground (step 4).
・ If there is an outlet with indoor ground, connect the ground wire 21 to it.
5) The nail position of the marked part is measured with the MΩ meter 20 in order (step 5).
・ Because there is a possibility of multiple locations, be sure to measure all marked locations.
6) The insulation resistance value is judged to be high or low, and the location of water leakage is identified.
・ Specification is determined at the point with the lowest resistance.
-Or, set a criterion level, and determine all points below this level as water leaks.
[0017]
【The invention's effect】
As described above, the present invention first locates the hot water mat, then locates and marks the nail, and then measures the insulation resistance value to identify the location of the water leak. is there.
1. By locating the nail, the point of water leakage due to nailing can be identified with points.
2. Since all the nail locations are inspected, water leaks at multiple locations can be detected reliably.
3. Since the MΩ meter is grounded and the MΩ meter is simply moved on the floor, it is easy to work and does not take much time.
4). Since the location of water leaks can be identified by point, if there is a request from the customer or construction, it is not necessary to peel off the extra flooring material at the time of repair, greatly reducing the time and cost of repair compared to the conventional example. Can do.
