Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor heating structure using joists and a floor heating pipe fixing member used in this structure. More specifically, the present invention uses a floor heating structure that is excellent in airtightness, feels a high perceived temperature without setting the room temperature high, and has excellent thermal efficiency, and a floor joist excellent in such performance and inexpensive. The present invention relates to a floor heating structure and a floor heating pipe fixing member used in the structure.

[0002]

BACKGROUND OF THE INVENTION Conventionally, heating appliances such as oil stoves have been widely used as room heating appliances. Heating with such a heating appliance contaminates indoor air due to combustion, and is therefore not desirable as heating for allergic diseases such as asthma, respiratory diseases, or home heating for the elderly, dwarfs and the like.

[0003] Heating appliances such as electric stoves and air conditioners are also used. Although such a heat appliance does not contaminate the indoor air due to combustion, it also convects the fine dust in the room to heat the entire room by convection, thus contaminating the room and causing allergic diseases and the like as described above. Not suitable for certain facilities.

[0004] Further, even if the room is heated using any of the above-mentioned heating appliances such as an oil stove or the like, the perceived temperature is perceived to be low. There is a need. In addition, since such a heating device is installed in each room, when moving from a heated room to an unheated place such as a corridor or a toilet, an elderly person or the like may receive a heat shock due to a temperature difference. In order to prevent such a heat shock, it is necessary to heat the entire house so that the temperature difference is reduced and the heating temperature is set to a temperature higher than the perceived temperature.

[0005] Further, in a house having excellent heat insulation and airtightness, it is necessary to heat the room above the sensible temperature by using the above-mentioned heating equipment and supply the humidity so as to keep the room humidity at an appropriate level. As described above, the temperature and the humidity become high, and mold, mites and the like are easily generated. Also, in the windows where the temperature difference is remarkable, such replenished water tends to condense, and this dew forms not only causes mold and damages health, but also causes problems such as premature aging of buildings. there were.

In the above-described heating method, warm air rises and cool air falls, so that a considerable temperature difference occurs between the ceiling and the floor in the room. Therefore, if the floor itself is used as the heat source, the temperature difference between the upper and lower parts of the room will be reduced,
Heating efficiency is greatly improved. From this perspective, floor heating is increasingly being adopted.

[0007] Floor heating is a heating method in which a warm water pipe or the like is arranged under the floor to warm the floor itself. Since the entire floor becomes warm, a very comfortable living space can be formed. In such floor heating, after the hot water pipe is laid, the floor material is laid on it, so it is necessary to remove the floor material to move the hot water pipe once piped,
You have to do very large works.

[0008] Originally, in floor heating, it is not necessary to move the hot water pipe once piped, except for accidents such as breakage of the pipe. However, after a long time has passed since the hot water pipe was actually laid and the floor was stretched, the piping position may be shifted due to the inherent elasticity of the hot water pipe. Various jigs have been proposed to prevent such displacement of the piping position. However, in the case of a Japanese wooden building, the hot water pipe is often arranged on a heat insulating material, and therefore, the hot water pipe is fixed to a heat insulating material made of a foamed resin or the like. Therefore, with time, the hot water pipe may move together with the heat insulating material and uniform floor heating may not be achieved.

In addition, fixing the hot water pipe to the heat insulating material has a problem that positioning is difficult because the heat insulating material is flexible.

[0010]

SUMMARY OF THE INVENTION An object of the present invention is to provide a hot water pipe fixing device for floor heating, in which the positioning of the hot water pipe is easy and the piping position of the hot water pipe does not shift for a long period of time.

Another object of the present invention is to provide a floor heat insulating structure using the hot water pipe fixture.

And a vertical cross-sectional shape capable of holding the hot water pipe integrated with the support on the side where the locking portion of the support rises is inverted Ω.
A locking member insertion hole for fixing the support to the joist is formed in the locking portion formed at both ends of the support. It is characterized by being established.

In the floor heating structure of the present invention, a hot water pipe is fixed by using a joist. A plurality of joists arranged substantially in parallel, and the lower surface and the lower surface of the joist are substantially flush.

A floor heating pipe fixing member provided, wherein the hot water pipe is fitted and fixed to a pipe fixing portion having an inverted Ω-shaped vertical cross-sectional shape of the floor heating pipe fixing member.

[0014] The floor heating pipe fixing member of the present invention is fixed to the side surface of the joist with a nail or a wood screw. And
The hot water pipe can be easily piped by sandwiching the hot water pipe between the pipe fixing portions having the inverted Ω-shaped vertical cross section formed on the pipe fixing member for floor heating.

Further, in the floor heating structure of the present invention, a heat insulating material is fitted between the joists, and a metal foil such as aluminum foil is stretched on the heat insulating material so as to cover the boundary between the joists and the heat insulating material. Furthermore, after the floor heating pipe fixing member is nailed or wood screwed between the joists, the hot water pipe is inserted into the pipe fixing portion having a vertical Ω-shaped vertical cross section formed on the floor heating pipe fixing member. It has a sandwiched structure,
The gap that may occur between the insulation and the joist is covered with a metal sheet, improving the airtightness under the floor and releasing the heat of the hot water pipe from this metal sheet, so that the floor is evenly heated. be able to.

Further, since the floor heating pipe fixing member is firmly fixed to the joist, the piping position of the hot water pipe does not shift for a long period of time.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A floor heating pipe fixing member according to the present invention has a form in which both ends are raised at right angles to a support, and a locking member for driving a nail or the like into the raised both ends. An insertion hole is provided. Then, a nail or the like is driven into the locking member insertion hole to fix the floor heating pipe fixing member of the present invention between the joists.

, Common members are given the same numbering.

As shown in FIG. 1, the floor heating structure of the present invention uses a joist to fix a hot water pipe and has the following configuration. That is, the floor heating structure of the present invention includes a plurality of joists arranged substantially in parallel, a heat insulating material fitted between the joists such that the lower surface and the lower surface of the joists are substantially flush. A heat-dissipating metal sheet, which covers the top surface of the heat insulating material and whose end extends to the side surface of the joist and covers the contact portion between the joist and the heat insulating material; It consists of a floor heating pipe fixing member arranged substantially perpendicular to the length direction of the joist between the joists, and a hot water pipe fixed by the heating pipe fixing member. The floor heating pipe fixing member is formed so that both side ends thereof stand substantially at right angles to form a locking portion, and a support having a length that can be fitted between the joists, and a locking portion of the support. Has at least one pipe fixing portion having an inverted Ω-shaped vertical cross-section that is integrated with the support and that can clamp the hot water pipe on the side where the stand is raised, and is formed at both end portions of the support. The locking portion is provided with a locking member insertion hole for fixing the support to the joist. Further, the floor heating pipe fixing member is formed with a hot water pipe fixing portion having an inverted Ω-shaped cross section for fixing the hot water pipe.

The floor heating structure of the present invention will be described below in detail with reference to the drawings.
A joist 1 arranged substantially in parallel, a heat insulating material 2 fitted between the joists, a heat dissipating metal sheet 3 arranged substantially vertically on the joist side and laid on the heat insulating material; It comprises a hot water pipe 4 provided on a metal sheet and a fixing member 5 for fixing the communication pipe.

In the floor heating structure of the present invention, the fixing member 5
The joist 1 to which is nailed is provided to support a floor in a wooden building. As shown in FIG. 1, the joists are installed on concrete or as shown in FIG. The thickness of the joist 1 in the vertical direction and the horizontal direction is not particularly limited, and a commonly used one can be used. For example, this thickness is almost the same,
It may be about 100 mm. The thickness in the vertical direction may be different from the thickness in the horizontal direction. For example, a joist having a ratio of the thickness in the vertical direction to the thickness in the horizontal direction (the thickness in the vertical direction / the thickness in the horizontal direction) of about 0.1 to 10 can be used.

The interval between adjacent joists is 100 to 1000
mm, but joists are usually laid at intervals of about 250 mm. As shown in FIG. 3, the heat insulating material 2 is provided on the joist 1 and the adjacent joist 1, and is arranged such that the lower surface thereof is flush with the lower surface of the joist 1.

Urethane is used as a heat insulating material.
A foamed resin heat insulating material obtained by foaming a resin such as polyethylene or polypropylene is used. Such a foamed resin heat insulating material can reduce the resin by, for example, 100 times or less, preferably 30 times.
It is manufactured by foaming at a foaming ratio of about 80 times. Such a foamed resin heat insulating material has excellent heat insulating properties, and also has excellent elasticity and sound insulating properties.

As the heat insulating material, cuts are formed in a straight line at the side edges of the heat insulating material having the expansion ratio as described above in a straight line over the entire length thereof, and the cuts are substantially perpendicular to the heat insulating material. A heat insulator such as that shown in FIG. 3 can be used. In FIG. 3, reference numeral 1 is a joist, and reference numeral 2 is a heat insulating material having a cut. Such a heat insulating material 2 can be easily inserted and arranged in a state of being closely attached between the joists 1, 1 when installed, and the interval between the joists 1 is slightly changed or a part of the joists 1 is slightly deformed. Even if no gap is formed. Therefore, outside air does not enter from the portion where the joist 1 and the heat insulating material 2 are provided, and the occurrence of dew condensation, icing and the like can be prevented. In addition, such a heat insulating material 2 can be easily installed even if the interval between the joists 1 is slightly narrow, does not cause swelling, and is excellent in workability. Further, even if the joist changes over time after the floor heating structure of the present invention is installed, no gap is generated in the abutting portion between the joist 1 and the heat insulating material 2, or the joist 1 absorbs moisture and expands somewhat. Even if the heat insulating material does not break or swell, no cold air enters and no dew condensation or icing occurs.

The thickness of the heat insulating material is generally about half of the vertical thickness of the joist. As the heat insulating material, commonly used glass fibers can be used, and further, the above-described foamed resin and glass fibers can be appropriately combined and used.

Further, a heat insulating material formed by integrating a heat radiating board on the upper surface of the above heat insulating material can also be used. Furthermore, a heat insulating material can also be arranged on the lower surface of the joist. As shown in FIG. 1, the heat-dissipating metal sheet 3 is laid on the upper surface of the heat-insulating material 2 so as to cover the heat-insulating material 2. It is laid so as to cover the joint part. This heat dissipating metal sheet 3
Is formed of a metal material having excellent thermal conductivity, such as aluminum and copper, in a layered form. The thickness of the metal layer of such a heat-dissipating metal sheet 3 is usually about 1 μm to 1 mm, preferably 1 μm to 200 μm, particularly preferably 10 to 100 μm. Since the metal sheet having such a thickness is lightweight and has a shape-following property, the metal sheet for heat radiation can be installed in close contact even when there is some unevenness on the upper surface of the heat insulating material.

The heat-dissipating metal sheet 3 is preferably provided with a metal layer 11 and an adhesive layer 12, as shown in FIG. It is preferable that the thickness of the adhesive layer is substantially equal to the thickness of the metal layer. With this level, the heat-dissipating metal sheet is not easily separated from the joist or the heat insulating material.

Further, as shown in FIG. 4B, a transparent protective layer 13 of silicon or the like can be provided on the metal layer 11 of the heat-dissipating metal sheet 3 as shown in FIG. In the metal sheet for heat dissipation provided with such a protective layer, the emissivity does not change for a long time because the metal layer is not oxidized,
Therefore, the heating cost is reduced.

The heat-dissipating metal sheet 3 provided with such an adhesive layer is provided in contact with the upper surface of the heat insulating material 2 and the side surface of the joist 1. This heat-dissipating metal sheet is provided with an adhesive layer, and by using such a sheet, the air-tightness of the floor heating structure of the present invention is maintained high, and dew condensation and icing are prevented.

Since the heat-dissipating metal sheet 3 has a metal layer, the heat from the hot water pipe is quickly absorbed, and the absorbed heat is efficiently converted into radiant heat on the entire upper surface of the heat-dissipating metal sheet and radiated as radiant heat. . By employing such a heat-dissipating metal sheet, the floor heating structure of the present invention feels a high perceived temperature and reduces the heating cost (running cost). Moreover, since the heat-dissipating metal sheet is stuck to the side surface of the joist and the upper surface of the heat insulating material without any gap, it is possible to prevent the dissipation of heat from the contact portion between the heat insulating material and the joist and to prevent the invasion of cold air. Further, the metal sheet for heat radiation can be attached to the heat insulating material without using fixing means such as nails, so that the heat insulating material does not have holes, does not dissipate heat, and does not invade cold air.

As shown in FIG. 1, the hot water pipe 4 is disposed in the space between the floor plate and the metal sheet 3 for heat radiation, and is installed on the metal sheet for heat radiation via a fixing member. As such a hot water pipe 4, as shown in FIG. 5, a resin-coated pipe in which a synthetic resin such as polyethylene is coated on both inner and outer surfaces of a metal pipe 21 such as aluminum or copper is preferably used.

Examples of the coating material used in producing the resin-coated pipe include thermoplastic resins such as polyethylene, cross-linked polyethylene, polypropylene, polybutylene, and vinyl; and thermosetting resins such as urea resins and phenol resins. Among them, thermoplastic resins such as polyethylene and cross-linked polyethylene are particularly preferably used. Further, a metal pipe 21 such as aluminum and a coating resin 22 are provided.
May be formed via the adhesive layer 23. As shown in FIG. 5, the adhesive layer 23 may be formed by using a commonly used adhesive such as an acrylic adhesive or an epoxy adhesive, as shown in FIG. May be formed.

A hot water pipe whose inner and outer circumferences are covered with the above-mentioned resin is hardly rusted because the metal causing corrosion is not exposed, and has a small change in thermal conductivity over a long period of time. In addition, since the hot water pipe does not transmit oxygen and does not generate scale due to organisms in the pipe, the heating efficiency does not decrease. Furthermore, the color of the coated resin can be appropriately selected,
For example, even when water leaks occur, the pipes can be easily identified and the water leak pipes can be quickly replaced.

As described above, the hot water pipe 4 has better heat resistance than the synthetic resin pipe. For example, the temperature of the hot water in the hot water pipe can be set at 95 to 120 ° C. The working pressure is usually 10 to 20 kg / cm ²
It can be used for high-rise buildings. Also, even if the water in the pipe freezes, the pipe will not be damaged,
Do not leak. Such a hot water pipe can also be used for cooling.

Also, compared to metal pipes, hot water pipes are superior in corrosion resistance to acids and the like, and rust does not occur in the hot water pipes, the flow rate does not fluctuate, and no oxide precipitates are formed. Not corrode peripheral equipment, so heating efficiency is not reduced and running costs are not too high.
Further, since the pipe does not corrode, peripheral devices such as a hot water supply device are hardly damaged. Furthermore, no toxic substances such as patina generated when a copper pipe is used are not generated, and the resin-coated pipe is excellent in hygiene.

The diameter (outer diameter) of such a hot water pipe can be determined in consideration of the flow rate of the hot water, the heating area, the size of the hot water supply device, and the like. The hot water pipe used in the present invention has a thermal conductivity of 0.40 to 0.60 cal / cm sec · ° C. and excellent heat radiation per unit area.
The heat energy from the hot water quickly moves to the radiating laying plate and the floor plate, and the space between the floor plate and the radiating laying plate via the pipe fixing member described later, and the necessary amount of heat can be appropriately supplied.

The above-mentioned hot water pipe is a preferred example using a metal pipe whose inner periphery and outer periphery are covered with a resin.
In the present invention, in addition to such a resin-coated metal pipe, a conventionally used synthetic resin pipe such as polyethylene, polypropylene, or polybutylene, or a metal pipe such as an aluminum pipe, a copper pipe, or an iron pipe can also be used.

As shown in FIGS. 6 to 8, both ends of the floor heating pipe fixing member 5 of the present invention stand up substantially at right angles to form the locking portion 35 and can be fitted between the joists. A support 31 having a length, and a pipe fixing portion having an inverted Ω-shaped vertical cross-sectional shape capable of holding the hot water pipe integrated with the support 31 on the side where the locking portion 35 of the support 31 rises. 33 at least one. A locking member insertion hole 34 for fixing the support 31 to a joist is provided in a locking portion 35 formed at both side ends of the support 31.
Are drilled.

This floor heating pipe fixing member (fixing member)
5 is mounted on the heat-dissipating metal sheet between the joists 1 at right angles to the length direction of the joists, and is used as a fixing member for the hot water pipe 4.

The interval at which the fixing members are installed between the joists is not particularly limited. For example, the interval between the fixing members is within 4 m, preferably within 2 m. The fixing member may be provided near both ends of the joist in the longitudinal direction, or may be further provided near the central portion of the joist in the longitudinal direction.

As shown in FIG. 6, the fixing member 5 includes a support 31, a reverse Ω-shaped pipe fixing portion 33, and a locking portion formed by raising both ends of the support at substantially right angles. 35, and a locking member insertion hole 3 formed in the locking portion 35.
4 The groove 32 and the support 31 of the fixing member 5 are
It may be flat as shown in FIG. 6A, or may be formed as a groove as shown in FIG. 6C.
When the groove is formed, the support and the groove 32 may be integrally formed to form a groove, and the groove may be formed in a convex or concave shape. The shape of the groove (the cross-sectional shape in the direction orthogonal to the longitudinal direction of the fixing member) may be circular or polygonal, and the number of grooves formed is not particularly limited. When two or more grooves are formed as shown in FIG. 6 (D), the shapes of these grooves may be the same or different, and the formed grooves may be convex or concave as described above. Or a combination thereof.

As shown in FIG. 6B, the fixing member 5 is preferably provided with a groove 32 along the longitudinal side edge of the fixing member 5. The provision of the groove 32 makes it difficult for the fixing member 5 to be deformed even when an unnecessary stress is applied to the fixing member 5.

Inverted Ω-shaped fixing portion 33 for holding hot water pipe
As shown in FIGS. 6 and 7, the cross section of the fixing member 5 along the longitudinal direction is formed in an inverted Ω shape. At least one inverted Ω-shaped fixing portion 44 is provided on the support 31. When one inverted Ω-shaped fixing portion 33 is provided, it may be, for example, the central portion in the longitudinal direction of the fixing member.
In the case where three more parts are provided, they are provided appropriately, for example, near the both ends in the longitudinal direction and three places in the central part in the longitudinal direction.
Such an inverted Ω-shaped fixing portion 33 may be, for example, in a form shown in FIG. 7 or FIG. That is, as shown in FIG. 7, the inverted Ω-shaped fixing portion 33 is formed of an opening 41 and a pipe fixing portion 42, and the pipe fixing portion 42 and the opening 21
And are integrally connected continuously. The shape of the opening 41 may be such that both sections are formed in parallel as shown in FIG. 7 (A), and as shown in FIG. 7 (B), the central portion in the width direction projects and is formed by both sections. The gap may be in the form of “) (” (X) or “()” when viewed from above. In particular, as shown in FIG. (//)
When the hot water pipe is fixed, the pipe does not hit the edge of the opening, so that no damage is caused. After the pipe is fixed, the pipe is not detached due to the occurrence of an air hammer, but absorbs or disperses vibration and thermal expansion to prevent the detachment of the pipe.

Also, as shown in FIG. 6C, the pipe fixing portion 33 is formed in a groove shape in this way, so that the contact area between the pipe and the fixing member 5 can be increased, and therefore, the heat from the pipe can be increased. Is easily transmitted. Further, as shown in FIG. 6A, a groove-shaped hole 43 may be formed in a part of the inverted Ω-shaped fixing portion. By forming such an Ω-shaped fixing portion 33, a large-diameter pipe can also be fixed.

As shown in FIGS. 6 and 7, the inverted Ω-shaped fixing portion can be formed integrally with the support, but after these are separately formed, the inverted Ω-shaped fixing portion is formed. It may be fixed to a support.

For example, as shown in FIGS. 8 (A), 8 (B) and 8 (C), when the inverted Ω-shaped fixing portion and the support are separately formed, the inverted Ω-shaped fixing portion is formed by two. It may be formed from more than one part.

For example, in FIG. 8A, slits 46, 46 into which a metal piece can be inserted are formed in the width direction of the support 31,
By inserting the metal piece 43A into the slits 46 and bending the metal piece 43A so that the hot water pipe can be clamped, a fixing portion of the hot water pipe can be formed.
Further, as shown in FIG. 8B, the inverted Ω-shaped fixing portion 43B can be formed by using a wire or the like instead of a metal piece. Further, as shown in FIG. 8C, the inverted Ω-shaped
By fixing 3C on the support with rivets,
The fixing portion 43C is rotatable, and the fixing member 5 shown in FIG. 8C is convenient for fixing the hot water pipe at a curved portion of the hot water pipe.

As shown in FIGS. 8 (D) and 8 (E), sandwiching pieces 43D and 43E forming an inverted Ω-shaped fixing portion for sandwiching the hot water pipe are connected via elastic members 45 such as springs. Can be laid on the support 31. FIG. 8 (D) shows an embodiment in which the holding piece 43D is a single piece, and FIG.
Shows an embodiment in which this sandwiching piece 43E has two lines.
Thus, the holding piece 43 is provided on the support 31 via the elastic member 45.
By laying D and 43E, the holding pieces 43D and 43
Since the E can move back and forth, it is easy to install the hot water pipe.

The locking portion 35 of the fixing member 31 is provided with a locking member insertion hole 34 for fixing the fixing member 31 to a joist by nailing or wood screwing. Also,
Such nail holes or screw holes may be provided on the support 31. The nail holes or screw holes 50 provided in the support 31 can be used for integrating the fixing member and the heat insulating material.

The fixing member 5 having the above configuration is
It is preferable to use a metal such as iron, brass, copper, or aluminum. When this fixing member is made of metal, it can be manufactured by punching, which is more economically advantageous than melt molding using resin. In addition, since metal generally has higher thermal conductivity than resin, heat conduction to the heat-dissipating metal sheet is good, and the floor can be uniformly heated. Further, the metal fixing member can be made thinner than the resin fixing member.

However, the fixing member of the present invention can be made of resin, or can be formed by combining metal and resin. When forming the fixing member using a resin, a thermoplastic resin such as ABS resin, polyamide, polyethylene, polypropylene, and fluororesin; a thermosetting resin such as epoxy resin, urethane resin, acrylic resin, and urea resin phenol resin; Can be used alone or in combination.

Further, it is also possible to use a metal as the core material and use a resin such as a fluororesin so as to cover the core material. The fixing member encapsulated with such a resin does not rust for many years. Moreover, for example, a fixing member covered with a fluororesin has excellent thermal conductivity.

Next, a method of constructing a floor heating structure using joists will be described. The floor heating structure using the joist of the present invention can be constructed as follows. First, after concrete is cast to create a slab foundation, or after a large scale is installed to create a slab foundation, the joists are arranged so that they are almost parallel to each other by fixing means such as nails and concrete nails. Fix on top.

Next, a heat insulating material is laid in contact with the joists. The heat insulating material used for the floor heating structure of the present invention has a specific notch. Such a heat insulating material is arranged in a state of being closely attached between the joists. The arranged heat insulating material can be laid without a gap between the joists or a part of the joists being deformed so as to cause no gap or slack.

When such a heat insulating material is laid, the airtightness is maintained even if the joist is deformed due to the aging, so that a floor heating structure with little heat dissipation can be obtained. Next, a heat dissipating metal sheet is placed on such a heat insulating material.

In order to place the heat-dissipating metal sheet on the heat-insulating material, it is possible to use means for applying an adhesive in a layer on one surface of the heat-dissipating metal sheet or on the upper surface of the heat-insulating material. Further, a heat dissipating metal sheet in which an adhesive layer is provided in advance on one side of the heat dissipating metal sheet can also be used. In particular, when a heat-dissipating metal sheet is attached to a heat-insulating material using a heat-dissipating metal sheet provided with an adhesive layer, there is no gap between the heat-insulating material and the heat-dissipating metal sheet. There is no danger of breaking the heat insulating material or peeling off the heat insulating material and the metal sheet for heat radiation.

Further, since the portion of the metal sheet for heat dissipation provided with the adhesive layer, which is in contact with the joist, is also adhered to the side surface of the joist via the adhesive layer, even if there is a gap in the contact portion between the joist and the heat insulating material. The gap is securely closed to prevent heat dissipation or cold air intrusion. In addition, in the summer, warm air is prevented from entering, and cooling costs are not required.

The heat dissipating metal sheet may be one previously placed on the heat dissipating metal sheet on one side of the heat insulating material. Furthermore, it is also possible to use a heat-insulating material in which a heat-dissipating metal sheet is formed in a layered form on one side of the heat-insulating material and lay the heat-insulating material in contact with the joists.

After the heat-dissipating metal sheet is placed on the side surfaces of the joists and the heat insulating material as described above, the fixing member is placed in contact with the joists. Means for attaching the joist and the fixing member include fixing means such as screws, nails, screws, tacks, and staplers, but are not limited to these fixing means. Before attaching the fixing member to the joist and the heat dissipating metal sheet, the heat dissipating metal sheet is provided in a layered manner on the side of the joist by an attaching means or the like, and then the fixing member is brought into contact. By installing the fixing member in this way, even if excessive stress is applied to the heat-dissipating metal sheet after sticking, the heat-dissipating metal sheet does not peel off from the joist.

The method of fixing the fixing member on the heat-dissipating metal sheet is not limited. For example, an adhesive layer may be provided on the bottom of the fixing member, and the fixing member may be fixed on the heat-dissipating metal sheet via the adhesive layer. Further, it can be fixed on the heat-dissipating metal sheet using a commonly used fixing means such as a nail or a tack. Alternatively, both ends of the fixing member are bent at substantially right angles, and the both ends bent at substantially right angles are placed in contact with the joists and installed by the fixing means, so that the metal sheet for heat radiation and the fixing member are not used with the adhesive. Can also be fixed.

The fixing member abuts on the metal sheet for heat dissipation and the joist, and is provided at both ends of the joist in a direction substantially perpendicular to the longitudinal direction of the joist. The fixing member is further provided near the center of the joist in the longitudinal direction. It can also be provided.

Next, after the fixing member is attached to the joist, a hot water pipe is installed. The hot water pipe used in the floor heating structure of the present invention does not require a bending machine or a joint at the time of installation, and does not require a heating machine used at the time of installing the resin pipe. Or, since a welding machine or the like is not required, labor costs and equipment costs when the floor heating structure of the present invention is constructed can be significantly reduced.

In the floor heating structure of the present invention, when a metal pipe whose inner and outer circumferences are coated with resin is used as the hot water pipe, the coefficient of linear expansion of the coated metal pipe is usually 1 to 3 × 10 ^{−. 5} / ° C, one order of magnitude smaller than resin pipes, and a tensile modulus of elasticity of 1000 kg / c
Since m ² is about one thousandth smaller than that of a metal pipe, cracks do not occur in concrete even when this hot water pipe is embedded in concrete. Thus, the floor heating structure can be constructed by burying the hot water pipe in the concrete.

Further, the hot water pipe can greatly reduce the number of connection joints of the pipe, and can be easily cut in spite of having such characteristics.

According to the floor heating structure of the present invention, a floor heating pipe fixing member is fixed to this joist utilizing a joist which is an essential component in Japanese wooden construction. The hot water pipe is fixed. Further, a heat dissipating metal sheet is disposed on the lower surface of the floor heating pipe fixing member, and a heat insulating material is laid on the lower surface of the heat dissipating metal sheet. Since the contact portion between the heat insulating material and the joist is also covered with the metal sheet for heat dissipation, warm air does not leak from the contact portion between the heat insulating material and the joist. Also,
Since the hot water pipe fixing part is formed on the floor heating pipe fixing member fixed to the joist, the hot water pipe can be piped simply by fitting the hot water pipe into this fixing part, and the positioning of the hot water pipe is easy. . Further, since the hot water pipe is firmly fixed, the hot water pipe does not move with time, so that floor heating can be performed uniformly over a long period of time.

Further, in the floor heating structure of the present invention, the room is directly and uniformly heated by the heat transfer from the floor, convection does not occur, and fine dust is not dispersed in the room. Further, the heat transferred from the hot water pipe to the heat-dissipating metal sheet is efficiently converted into radiant heat, and the radiant heat also provides heating. Therefore, even if the room temperature is set lower, the perceived temperature is not felt lower, and the heating cost is reduced. Since there is no need to raise the room temperature in this way, the room does not dry and it is not necessary to supply new humidity.

Further, since the floor heating structure of the present invention can heat all the rooms in the house, there is no temperature difference between the rooms, so that heat shock is prevented. Further, the floor heating structure of the present invention does not need to set the room temperature to a high temperature, and accordingly does not need to supply humidity for preventing drying. Accordingly, dew condensation and icing due to replenishment of humidity are prevented, and the environment does not become hot and humid. As a result, it is possible to effectively prevent the occurrence of ticks, molds, and the like, and to prevent aging of the house due to the formation of dew and freezing.

Further, the floor heating structure of the present invention is excellent in heat insulation, and can be used as a cooling facility by passing cold water through a hot water pipe.
