Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor heating mat in which pipes for flowing a heat medium are laid, an inspection method and an inspection apparatus for an abnormal construction, and a floor heating apparatus combined therewith.

[0002]

2. Description of the Related Art In general, a pipe for circulating a heat medium such as hot water is provided inside a floor heating mat. When installing such a floor heating mat under a floor in a house or the like, usually a floor heating mat is laid on a base plywood, and a floor material such as a flooring material is fixed thereon with nails or the like. And finish it.

[0003] The places where nails are to be nailed are the portions where small joists are arranged at predetermined intervals in the floor heating mat, and the pipes in the floor heating mat are connected to the locations where these small joists are located. It is stretched to avoid. In addition, a portion of the surface of the floor heating mat corresponding to the location where the small joists are located is usually colored or the like to facilitate identification of the location.

[0004] The work of fixing the flooring material with nails is performed while visually confirming the locations where the joists are located, using the coloring etc. as a guide. It may be driven. In addition, if a nail penetrates the pipe, it will lead to water leakage, etc., but if the nail is stuck in the pipe, the worker may not notice the damage itself because hot water etc. does not leak immediately because the nail is stuck. .

[0005] For this reason, various inspection methods and inspection apparatuses for inspecting after installation whether or not the nail for fixing the floor material has damaged the piping in the floor heating mat have been proposed.

Japanese Patent Application Laid-Open No. 5-180723 discloses an apparatus for inspecting whether or not a nail has penetrated a pipe based on whether or not there is electrical conduction. In this device, a conductive sheet is laminated on the surface of the floor heating hot water mat, and whether or not the nail penetrates the pipe is determined by the presence or absence of electrical conduction between the conductive sheet and the hot water in the pipe. Is to be inspected.

Japanese Patent Application Laid-Open No. 2-293542 discloses that
A technique is disclosed in which a conductive layer is coated on the inner surface and the outer surface of a pipe, respectively, and whether or not a nail has penetrated the pipe is detected based on the presence or absence of conduction between the conductive layers.

[0008]

In such a conventional technique, it is possible to inspect whether or not the nail that has been driven has penetrated the pipe after the nail has been driven. Since it is impossible to check whether or not the nailing point is appropriate, the operator must visually determine the coloring spot on the surface of the floor heating mat as a guide.

However, if the floor material is placed on the floor heating mat, the colored portion is covered by the floor material and is hidden. Therefore, when the nail is actually driven, whether or not the location is on the small joist is accurately determined. There was a problem that it was difficult to judge.

Further, according to the conventional technique, when the nail does not penetrate the pipe, it cannot be detected even if the nail is driven into a place other than the area where the small joist exists. For this reason, nails driven into places other than small joists may be left unattended, and when the floor heating mat shrinks due to aging, etc., the floor material fixed with nails and the shrinked floor heating mat may There was a problem that a gap was formed between the floors and a floor was formed.

The present invention has been made in view of such problems of the prior art.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Each drawing shows an embodiment of the present invention. As shown in FIGS. 1 and 2, the floor heating mat 10 includes a base sheet 11 made of foamed polyethylene or the like.
A pipe 12 composed of a cross-linked polyethylene pipe for passing a heat medium such as hot water therein is stretched around the meandering circuit. At the end of the floor heating mat 10,
There is a header section 16 having an inlet for feeding hot water to the internal pipe 12 and an outlet for discharging hot water that has passed through the pipe 12, and is a source of hot water through the header section 16. Floor heating device not shown and floor heating mat 1
0 is connected.

In the floor heating mat 10, a pipe 1 is provided.
A small joist 14 is provided by sewing between the two, and a magnetic sheet 15 made of a magnetic material is laminated on a portion of the surface of the floor heating mat 10 corresponding to an upper part of the small joist 14. The floor heating mat 10 has a thickness of about 12 mm, the outer diameter of the pipe 12 is about 7.2 mm, and the inner diameter is about 5 mm.

When the floor heating mat 10 is mounted on the floor, first, the floor heating mat 10 is spread and laid on the base plywood, and a floor material 22 such as a flooring material is laid thereon. A fixing member such as a nail is driven into the joint portion of the base plate to reach the base plywood and fixed. The floor material 22 such as a flooring material is used for the floor heating mat 10.
The nail to be fixed on the upper part is made of a magnetic material such as iron, and is originally intended to be driven into a place where a small joist is present, that is, a place where the magnetic sheet 15 is stuck (punch designation area). .

FIG. 3 shows a circuit configuration of a floor heating mat construction abnormality inspection apparatus according to an embodiment of the present invention. The floor heating mat construction abnormality inspection apparatus 30 includes an inspection processing general control unit 41 that controls the inspection operation in an integrated manner. The inspection processing general control unit 41 starts and stops inspection and performs various setting operations. And a display unit 43 for displaying inspection results and the like. Here, a liquid crystal display is used as the display unit 43.

The floor heating mat construction abnormality inspection apparatus 30
A magnetic material detection unit 44 for detecting the presence or absence of a magnetic material;
And a moving distance detecting section 45 for measuring a moving distance of the magnetic material detecting section 44 on the floor heating mat 10. The magnetic material detecting unit 44 and the moving distance detecting unit 45 are housed in a sensor box (not shown) that can freely move on the floor material after construction, and the moving distance detecting unit 45 includes a roller attached to the sensor box. The moving distance is measured based on the number of rotations of.

The driving designation area identifying section 46 is a magnetic sheet 15 in which the detected magnetic material is laminated on the small joist 14 based on the appearance pattern of the magnetic material detected by the magnetic material detecting section 44. It is a circuit part for identifying whether or not the above is true. When a magnetic material is detected at a location other than the location identified by the driving designation area identifying section 46 as the magnetic sheet 15, the fixing member identification section 47 nails the magnetic material into a location other than the small joist 14. It is a circuit portion that is determined to be the fixing member.

For example, when a magnetic material having a constant width is detected at regular intervals, the specified area 46 is identified as the magnetic sheet 15. Alternatively, when the magnetic material is not present discretely but continuously detected over a predetermined area or more, it is determined that the magnetic material is the magnetic sheet 15.

The fixing member identifying section 47 identifies a magnetic material detected in a region other than the area determined by the driving designation area identifying section 46 as the magnetic sheet 15 as a nail or the like, or detects a magnetic material discretely. When they are detected, they are determined to be nails or the like driven into places other than the small joists 14.

Next, the operation will be described. When the floor heating mat 10 is laid on the base plywood and the floor material is placed thereon, the floor heating mat 10 is covered with the floor material, so that the place where the small joist 14 exists can be directly visually confirmed. You can't do that. Therefore, at the time of construction, the nailing operation is performed while sequentially checking with the floor heating mat construction abnormality inspection device 30 whether or not the nail is to be driven into the designated driving area where the small joists 14 are present.

Since the magnetism passes through the floor material, it is possible to detect the location where the magnetic material exists even from above the floor material. Therefore, if the magnetic sheet 15 is laminated only at the position where the small joist 14 is present, even if the magnetic material 15 is present, even if the magnetic material 15 is present, even if the magnetic sheet 15 is present, the relevant portion may be located in the driving designation area where the small joist 14 exists. It can be recognized whether or not there is. Thereby, it is possible to prevent a nail or the like from being accidentally driven into a portion other than the portion where the small joist 14 exists.

In the inspection after the work of fixing the floor material is completed, it is determined whether or not the detected magnetic material is the magnetic sheet 15 based on the detected appearance pattern of the magnetic material. Here, as shown in FIG.
Since the magnetic material 5 is provided in a belt shape, whether the detected magnetic material is the magnetic sheet 15 is identified based on whether or not the appearance pattern of the magnetic material appears in a belt shape.

That is, the moving distance of the sensor box is detected by the moving distance detecting section 45, and based on the presence / absence of the detection by the driving designation area identifying section 46 and the information of the moving distance measured by the moving distance detecting section 45. Then, it is determined whether or not the magnetic material is spread in a belt shape.

When the magnetic material is detected in an area other than the area determined to be the magnetic sheet 15 by the driving designation area identifying section 46, the fixing member identifying section 47 determines that the magnetic material is a fixing member such as a nail. Display unit 43 indicating that the inspection has failed.
Display above and emit a predetermined warning sound. On the other hand, when the magnetic material is not detected in a portion other than the magnetic sheet 15, the inspection is displayed on the display unit 43 and an inspection result signal 48 indicating that fact is output.

Next, the floor heating mat construction abnormality inspection apparatus 3
The floor heating device main body 100 used in combination with 0 will be described. FIG. 4 schematically shows a state in which the floor heating mat 10, the floor heating mat construction abnormality inspection device 30, and the floor heating device main body 100 are connected to each other. The floor heating apparatus main body 100 and the floor heating mat 10 are connected by a connection pipe 101 for supplying hot water and recovering the hot water that has passed through the inside of the floor heating mat 10. The inspection result signal 48 from the floor heating mat construction abnormality inspection device 30 is input to the floor heating device main body 100.

The floor heating apparatus main body 100 supplies hot water to the floor heating mat 10 until the inspection result signal 48 indicating that there is no construction abnormality is input from the floor heating mat construction abnormality inspection apparatus 30.

A circulation control unit 115 including a pump or the like for sending to zero is provided.

FIG. 6 shows a flow of the operation performed by the floor heating apparatus main body 100. When the floor heating device main body 100 receives the inspection result signal 48 from the floor heating mat construction abnormality inspection device 30 (step S301; Y), it determines whether the input inspection result signal 48 is a genuine signal (step S301). S302).

The inspection result signal 48 is a digital signal with an error detection code coded in a predetermined format, and the floor heating apparatus main body 100 determines whether the signal is authentic based on whether or not the code information has arrived. And determine
The presence / absence of a transmission error is checked based on the error detection code added to the code.

By using such code information as the inspection result signal 48, it is possible to prevent a worker from inputting a pseudo signal and falsifying the inspection result, or from erroneously recognizing the inspection result due to noise or the like.

If the signal is a genuine inspection result signal 48 (step S302; Y) and the content indicates that the inspection has passed (step S303; Y), the inspection processing control unit 112
Registers information indicating that the inspection has passed in the nonvolatile memory 113 (step S304). If the inspection result signal 48 indicates that the inspection has failed, the information indicating that the inspection has passed is deleted (step S305). As a result, even if the test has been passed once in the non-volatile memory 113, if the test is rejected again, the registration of the passed test is canceled.

When there are a plurality of floor heating mats 10 connected to the floor heating apparatus main body 100, the pass / fail of the inspection is registered in the nonvolatile memory 113 for each floor heating mat 10. In this case, the floor heating mat construction abnormality inspection apparatus 30 adds the identification number of the floor heating mat 10 to be inspected to the inspection result signal 48. The number of the mats 10 for floor heating to be connected and the like are registered in the floor heating apparatus main body 100 in advance. When receiving the inspection result signal 48 indicating success, the floor heating apparatus main body 100 registers the information indicating the inspection success in the nonvolatile memory 113 as a set with the identification number assigned to the inspection result signal 48.

FIG. 7 shows a flow of the operation of the floor heating apparatus main body 100 when the normal heating operation is started.
When a floor heating start instruction is received from the remote control operation unit or the like (step S401; Y), the floor heating apparatus main body 100 checks whether or not the inspection passed is registered in the nonvolatile memory 113 (step S402). When the inspection passed is registered for all the connected floor heating mats 10 (step S402; Y), the floor heating apparatus main body 100 causes the combustion control unit 114 and the circulation control unit 115 to function to perform floor heating. The operation starts (step S403).

On the other hand, the floor heating mat 1 to which hot water is to be supplied
If at least one of 0 is not registered in the nonvolatile memory 113 as “passed” (step S40)
2; N), a warning indicating that the pass of the test has not been registered is displayed on the remote control operation unit, and a predetermined warning sound is emitted (step S404).

As described above, when the inspection completion is not registered, the normal floor heating operation is prohibited, so that the inspection for determining whether or not a nail has been driven into a portion where the small joist 14 does not exist at the time of construction is omitted. It is also possible to prevent a truing operation that makes false inspection results.
