Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water floor heating floor excellent in workability.

[0002]

2. Description of the Related Art As a hot-water floor heating floor for heating by passing hot water through a hot-water pipe provided on a floor base, FIG.
As shown in FIGS. 9A and 9B, a floor heating floor integrated with a floor finishing material in which a floor finishing material 51 having a built-in hot water pipe 52 in advance is laid on a floor foundation 53, FIG. As shown in (b), a hot water mat 61 having a built-in hot water pipe 62
Is laid on the floor substrate 64, and the floor finishing material 63
There is a floor heating floor of a floor finishing material separation type in which a floor is laid.

[0003] In a floor heating floor integrated with a floor finishing material, as described above, the hot water pipe 52 is built in the floor finishing material 51 in advance, so the floor finishing material 51 must be laid on the floor foundation 53. In the case where the floor finishing material 51 is nailed to the floor substrate 53, if the designated position is nailed, there is an advantage that the hot water pipe 52 built in the floor finishing material 51 is not damaged. is there.

However, since the warm water pipe 52 is divided for each floor finishing material 51, the floor finishing material 51 is
When laying on the floor finishing material 3, the hot water pipes 52 built in the adjacent floor finishing material 51 must be sequentially connected via a connector or the like, and the workability of laying the floor finishing material 51 is poor. There is.

On the other hand, in the floor heating floor of the floor finishing material separation type, the hot water mat 61 laid on the floor substrate 64 is used to cover a certain floor heating area regardless of the size of the floor finishing material 63. Size (for example, floor finishing material 6)
3, the number of connecting points of the hot water pipes 62 is smaller than that of the floor heating floor integrated with the floor finishing material, and the hot water mat 61 can be efficiently placed on the floor substrate 64. There is an advantage that it can be laid on top.

However, unlike the floor heating floor integrated with floor finishing material, such a floor heating floor always requires two processes of laying the hot water mat 61 and laying the floor finishing material 63. The workability of the entire floor heating floor is not good.

When laying the floor finishing material 63, the floor finishing material 63 may be nailed to the hot water mat 61 laid on the floor substrate 64.
In contrast to this, the floor finishing material 63 to be laid later is not reliably positioned, so that if the relative positions of the two are shifted, even if the nail is hit at a predetermined nailing position, the nail will not be heated by the hot water pipe 62. There is also a drawback that construction mistakes such as penetrating through are easily generated.

On a normal floor heating floor, it is common to heat the floor only in the center of the room. The center of the room where the hot water mat 61 is laid and the periphery of the room where the hot water mat 61 is not laid. Therefore, as shown in FIG. 9B, for example, as shown in FIG. 9B, the peripheral portion of the room where floor heating is not performed has a higher floor base 64 than the central portion of the room where floor heating is performed. Also, there is a problem that the finishing height of the floor must be adjusted by using a thick floor finishing material.

Further, as an intermediate floor heating floor of the above-mentioned floor finishing material integrated type and floor finishing material separation type, as shown in FIG. 10 (a), a pipe accommodation groove for accommodating a hot water pipe 74 on the back surface. After laying the floor finishing material 71 having the 72 formed thereon on the floor base 73 as shown in FIG. 3B, the pipe is cut from the end face side of the floor finishing material 71 as shown in FIG. In some cases, a hot water pipe 74 is inserted into the accommodation groove 72.

The use of such a floor heating floor can eliminate the disadvantages of the floor heating floor integrated with the floor finishing material and the floor heating floor of the floor finishing material separated type as described above. It is time-consuming to pass a long hot water pipe 74 into the pipe accommodating groove 72 of the already finished floor finishing material 71 while making a U-turn.
The floor heating floor cannot be constructed efficiently.

Accordingly, an object of the present invention is to provide a hot water floor heating floor that can be efficiently constructed without adjusting the finishing height, in view of the above-mentioned problems of the conventional hot water floor heating floor. To provide.

[0012]

Means for Solving the Problems and Their Effects To solve the above-mentioned problems, the invention according to claim 1 has a floor finishing material laid so as to cover a hot water pipe unit placed on a floor base. A hot-water floor heating floor, wherein the hot-water pipe unit has a hot-water pipe shaped in a predetermined pipe pattern previously fixed to an upper surface of a base sheet having good heat conductivity through which an adhesive is transmitted. The floor finishing material has a pipe receiving groove formed on the back surface thereof for fitting the hot water pipe therein, and the adhesive for fixing the rear surface of the floor finishing material and the upper surface of the base material sheet is formed on the base material. The present invention provides a hot water floor heating floor in which the hot water pipe unit and the floor finishing material are integrally adhered and fixed to a floor base by transmitting a material sheet. The “substrate sheet through which the adhesive is permeable” refers to a substrate sheet which is formed of a material having an adhesive permeating property and a substrate which actively forms an adhesive through hole or the like. Sheets are also included.

As described above, in this hot-water floor heating floor, unlike the floor heating floor integrated with the floor finishing material, the floor finishing material does not have a built-in hot water pipe. While fitting the hot water pipe of the placed hot water pipe unit into the pipe receiving groove, laying the floor finishing material with the adhesive applied on the back side on the floor base sequentially, the floor finishing material via the adhesive And the base sheet of the hot water pipe unit are adhered and fixed, and the floor base and the base sheet or floor finishing material are simultaneously bonded and fixed by the adhesive that has passed through the base sheet. Unlike the conventional floor heating floor of the separate floor finish material that must be fixed to the floor, there is no need to fix the hot water pipe unit by itself to the floor base, and to make the size of the hot water pipe unit itself to some extent Because it can be set very well, similar to the floor heating floor of the conventional floor finishing material separation type, the floor heating floor of the conventional floor finishing material integrated type must connect a hot water pipe between adjacent floor finishing materials The number of connection points of the hot water pipes is smaller than that of the above, and the floor heating floor can be constructed efficiently.

Further, the floor finishing material may be sequentially laid on the floor substrate while fitting the hot water pipe of the hot water pipe unit placed on the floor substrate into the pipe receiving groove. After laying on the floor base, like a conventional floor heating floor where hot water pipes pass through the pipe accommodation groove,
The need for a troublesome hot water pipe passing operation is unnecessary, and the floor heating floor can be easily constructed in a short time.

Further, in this hot water floor heating floor, unlike the conventional floor heating floor integrated with floor finishing material, a hot water pipe is not built in the floor finishing material, but is formed in the floor finishing material. Because the hot water pipe of the hot water pipe unit is housed in the pipe receiving groove, there is no step between the portion where the hot water pipe unit is placed and the other portion, and the conventional floor finish As with the floor heating floor integrated with the material, there is an effect that it is not necessary to adjust the finishing height of the floor.

In the hot water pipe unit, since the base sheet to which the hot water pipe is fixed has good thermal conductivity, the heat of the hot water passing through the hot water pipe is applied to the floor finish via the base sheet. The temperature is uniformly transmitted to the flooring material, and the temperature unevenness on the floor finishing material surface can be reliably suppressed. Therefore, it is not necessary to knead the soaking sheet into the floor finish, and the floor finish can be efficiently manufactured.

Further, in the case where the base sheet is formed of a metal foil having a large number of through holes, as in the hot water floor heating floor according to the second aspect of the invention, Since the expansion and contraction of the fixed hot water pipe is suppressed, the hot water pipe can be securely fitted into the pipe receiving groove formed in the floor finish material, and the work of laying the floor finish material can be performed smoothly.

[0018] In particular, as in the hot water floor heating floor according to the third aspect of the present invention, the base sheet is formed by a multi-layer sheet having a large number of through-holes, including a soaking layer made of metal foil. If you do, the stiffness will be stronger than the base sheet formed by the metal foil alone, and the base sheet will not be easily wrinkled when handling the hot water pipe unit,
Even when the base sheet is bent, it can be easily restored to the original state, so that good handling properties can be ensured.

[0019]

Embodiments will be described below with reference to the drawings. As shown in FIG. 1 and FIG. 2, the hot-water floor heating floor 1 is a floor base 10 made of a laminated board or the like.
And a hot water pipe unit 20 placed on the floor base 10, and a floor finishing material 30 laid on the floor base 10 to cover the hot water pipe unit 20 placed on the floor base 10. It is composed of

As shown in FIGS. 2 and 3, the hot water pipe unit 20 is a long hot water pipe 21 having a diameter of 5A, which is formed into a substantially rectangular plane by alternately making U-turns at both ends. The hot water pipe 21 is composed of a base sheet 22 to which the hot water pipe 21 is fixed, and the hot water pipe 21 is formed of cross-linked polyethylene.

As shown in FIG. 4, the base sheet 22 is made of an aluminum foil 24 having a thickness of 50 μm and a thickness of 30 μm.
m is a three-layer laminated sheet laminated with a polyethylene film 23 of m m and a paper-to-paper reinforced paper 25 having a basis weight of 23 g / m ³ , and has a size capable of completely covering the hot water pipe 21 shaped into a predetermined pipe pattern. have.

The base sheet 22 has a hot water pipe 2 on its upper surface, that is, on the surface of the polyethylene film 23.
1 is heat-sealed, and a large number of through-holes 22a having a diameter of about 38 mm are formed so as to avoid the hot-water pipe 21 which is heat-sealed.

The floor finishing material 30 includes a peripheral panel laid around a room where the hot water pipe unit 20 is not placed, and a hot water pipe 21 of the hot water pipe unit 20 placed at the center of the room. And a U-turn panel laid so as to cover a U-turn portion of the hot water pipe 21 in the hot water pipe unit 20. The peripheral panel is a main body panel. Panels with the same configuration as the above are used.

The main body panel is shown in FIGS. 2 and 5 (a),
As shown in (b), a panel base material 31 formed of a wooden board such as a 5-ply plywood or a 3-ply plywood, and a surface decorative material 32 such as a veneer attached to the surface of the panel base material 31
On the surface of the main body panel, there are formed three pseudo grooves 32a extending in the longitudinal direction and a plurality of pseudo grooves 32b extending in the lateral direction between the pseudo grooves 32a. On the back surface of the base material 31, a plurality of pipe accommodation grooves 31a for accommodating the linear portion of the hot water pipe 21 in the above-mentioned hot water pipe unit 20 are formed at regular intervals.

The U-turn panel also has basically the same structure as the main body panel, but as shown in FIG. An arc-shaped pipe housing groove 31b for housing the U-turn portion of the hot water pipe 21 is formed between the pipe housing grooves 31a.

A method of constructing the hot water floor heating floor constructed as described above will be described below. First, FIG.
As shown in (a), after laying the peripheral panel 30a on the floor base 10 from one side of the room where the floor heating floor is to be constructed, as shown in FIG. It is placed on the floor base 10 at a predetermined position. In this case, two sets of hot water pipe units 20 are used.

Next, as shown in FIG. 3C, when the U-turn panel 30c is laid so that the hot water pipe 21 of the hot water pipe unit 20 is fitted into the pipe receiving grooves 31a and 31b, the U-turn panel 30c is placed on the floor substrate 10. Since the placed hot water pipe units 20 are generally positioned, both ends of the hot water pipes 21 in each of the hot water pipe units 20 are pulled down to the lower side of the floor base 10, and connected to the main pipe under the floor.

Subsequently, as shown in FIG. 3D, the main body panel 30b is laid while the hot water pipe 21 is fitted into the pipe housing groove 31a. The peripheral panel 30a,
When the U-turn panel 30c and the main body panel 30b are laid, the adhesive is applied to the back surface of each panel except for the pipe accommodating grooves 31a and 31b.
As shown in FIG.
b and the U-turn panel 30c and the base sheet 22 of the hot water pipe unit 20 are adhered and fixed to each other, and the main body panel 30b and the U-turn panel 30c and the floor base 10 are connected to each other through the through holes 22a of the base sheet 22. Are simultaneously bonded and fixed.

In this way, the main body panels 30b are laid one after another, and as shown in FIG. 7 (e), the U-turn is formed so as to cover the U-turn portion on the opposite side of the hot water pipe 21 in the hot water panel unit 20. After laying the panel 30c, laying the peripheral panel 30a as shown in FIG. 1F, the hot water floor heating floor 1 as shown in FIG. 1 is completed.

As described above, this hot-water floor heating floor 1
The hot water pipe 21 of the hot water pipe unit 20 placed on the floor base 10 is not necessarily built in the floor finishing material 30 in advance like a floor heating floor integrated with a floor finishing material. 21 with the pipe accommodation grooves 31a, 31b
When the floor finishing material 30 (the main body panel 30b and the U-turn panel 30c) having the adhesive V applied to the back surface is sequentially laid on the floor base 10 while being fitted into the floor finishing material 30, as described above, Is fixed to the hot water pipe unit 20 and the floor base 10 at the same time, unlike the conventional floor heating floor of the floor finishing material separation type in which a hot water mat or the like must be fixed to the floor base, the hot water pipe unit 20 is used alone. Therefore, the size of the hot water pipe unit 20 itself can be set to some extent, so that the adjacent floor can be set in the same manner as in the conventional floor heating floor of the separated floor finishing material type. Compared with the conventional floor heating floor with integrated floor finishing material, which requires connecting the hot water pipe between the finishing materials, the number of connection points of the hot water pipe 21 is reduced, and the floor heating is efficiently performed. It may be applied to lower.

The hot water pipe unit 20 is connected to the floor substrate 1.
0, while the hot water pipe 21 is fitted into the pipe receiving grooves 31a and 31b, the floor finishing material 30 is
(Main panel 30b, U-turn panel 30c) may be sequentially laid on the floor base 10, so that the floor finish is laid on the floor base, and then from the end face side of the floor finish to the pipe receiving groove. Unlike a conventional floor heating floor through which a hot water pipe passes, it is not necessary to perform a laborious work of passing a hot water pipe, and the floor heating floor can be easily constructed in a short time.

In this hot water type floor heating floor 1, the floor finishing material 30 (main body panel 30b, U-turn panel 30
The hot water pipe 21 of the hot water pipe unit 20 is completely housed in the pipe housing grooves 31a and 31b formed in c),
Moreover, the base sheet 2 to which the hot water pipe 21 is fixed
2 has a thickness of less than 200 μm, so that no step is formed between the portion on which the hot water pipe unit 20 is placed and the other portion, and a conventional floor heating material separation type floor heating system. Unlike a floor, there is no need to adjust the finishing height of the floor.

In the hot water floor heating floor 1, the hot water pipes 21 are provided in the pipe receiving grooves 31 a, 3
1b, the hot water pipe unit 20 is reliably positioned with respect to the floor finish 30.
Even when the floor finishing material 30 is nailed to the floor substrate 10, it is possible to effectively prevent a construction error such as a nail penetrating a hot water pipe as in a conventional floor heating material separated floor heating floor. There is also.

In the hot water pipe unit 20, the base sheet 22 to which the hot water pipe 21 is fixed has a soaking layer made of an aluminum foil 24 having good thermal conductivity. The heat of the hot water passing through 21 is uniformly transmitted to the floor finishing material 30 via the base sheet 22,
Temperature unevenness occurring on the surface of the floor finishing material 30 can be reliably suppressed. Therefore, there is no need to knead the soaking sheet into the floor finishing material 30, and the effect that the floor finishing material 30 can be manufactured efficiently can be obtained.

When the hot water pipe 21 of the hot water pipe unit 20 expands and contracts, it becomes difficult to store the hot water pipe 21 in the pipe receiving grooves 31a and 31b formed on the back surface of the floor finishing material 30, but the hot water pipe 21 is fixed. The base sheet 22 is formed of a three-layer laminate sheet in which an aluminum foil 24 having poor elasticity is sandwiched.
The expansion and contraction of the floor finishing material 30 is surely suppressed, and the floor finishing material 30 must be laid while fitting the hot water pipe 21 into the pipe receiving grooves 31a and 31b formed on the back surface. it can.

The base sheet 22 in which the aluminum foil 24 is laminated with the polyethylene film 23 and the inter-sheet reinforcing paper 25 is stiffer than a base sheet formed of a single metal foil such as an aluminum foil. When the hot water pipe unit 20 is handled, the corners and the like of the base sheet 22 are unlikely to be wrinkled, and even when the base sheet 22 is bent, the base sheet 22 can be easily restored to the original state. Therefore, good handling properties can be ensured.

In the above-described embodiment, the aluminum foil 24 is made of the polyethylene film 23 and the paper
However, the present invention is not limited to this. For example, a base sheet having a three-layer structure in which an inter-sheet reinforcing paper is laminated on both sides of an aluminum foil or an aluminum foil It is also possible to use a base sheet having a two-layer structure in which a sheet between sheets is laminated on the back surface of the sheet.

In the above-described embodiment, the polyethylene film 23 forming the surface layer of the base sheet 22 is used.
The hot water pipe 21 is fixed to the base sheet 22 by heat-sealing the hot water pipe 21 to the base sheet 22. However, the present invention is not limited to this. When the hot water pipe 21 cannot be heat-sealed as in the case of the base material sheet, the hot water pipe 21 may be fixed to the base material sheet 22 using an adhesive means such as a hot melt adhesive.

In the above-described embodiment, the through holes 22a for transmitting the adhesive are formed in the base sheet 22. However, the present invention is not limited to this.
It is not necessary to form through-holes in the base sheet 22 in particular, as long as the material itself forming the material 2 has the adhesive permeability.

In the above-described embodiment, the aluminum foil 24 is used as the heat equalizing layer. However, the present invention is not limited to this, and various metal foils such as a copper foil and a non-woven fabric in which carbon fibers are entangled. Etc. can also be used.
However, needless to say, in order to suppress expansion and contraction of the hot water pipe 21, metal foil having poor elasticity must be used.

In the above-described embodiment, the base sheet 22 is used to cover both the straight portion and the U-turn portion of the hot water pipe 21 shaped into a predetermined pipe pattern. However, the present invention is not limited to this. Not something, for example,
It is also possible to use a base sheet that covers only the straight portion of the hot water pipe 21. However, in consideration of the expansion and contraction of the hot water pipe 21, it is desirable to fix not only the straight line portion but also the U-turn portion to the base sheet.
