DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor-heated building floor structure capable of heating by providing a hot water pipe on the floor.

[0002]

2. Description of the Related Art FIG. 1 shows a structure of a conventional floor heating building floor. In the floor structure shown in this cross-sectional view, a floor warm panel 8 is fixed between joists 7, and a surface floor panel 3 is fixed on the floor warm panel 8. The floor warm panel 8 has a heat equalizing plate 9 fixed to the upper surface. The heat equalizing plate 9 distributes heat uniformly over the entire upper surface. Furthermore, the heat equalizing plate 9 protrudes on both sides, and the protruding portion is fixed to the joist 7 by nailing or the like, and the floor warm panel 8 is fixed between the joists 7. The floor warm panel 8 is provided with a pipe groove 6 for receiving the hot water pipe 4 on the upper surface. The heat equalizing plate 9 is a part of the pipe groove 6,
The hot water pipe 4 is bent along the shape of the pipe groove 6.
Can be arranged in the pipe groove 6 in a state of enclosing the pipe. Further, the floor warm panel 8 insulates the periphery of the pipe groove 6 with a heat insulating material in order to prevent the heat of the hot water pipe 4 from being dissipated below the floor.

[0003] The building floor of this structure is constructed in the following steps. The floor warm panel 8 is fixed between the joists 7.
A heat equalizing plate 9 is fixed on the upper surface of the floor warm panel 8.
The hot water pipe 4 is inserted into the pipe groove 6 of the floor warm panel 8. The surface floor plate 3 is fixed on the upper surface of the soaking plate 9.

[0004]

In the building floor having the above structure, the floor heating panel 8 which is much more expensive than the surface floor panel 3 must be used. It has hindered its spread. Furthermore, the building floor shown in the figure is joist 7
The floor warm panel 8 is fixed between the panels, and further, the surface floor panel 3 is fixed on the floor warm panel 8 with the heat equalizing plate 9 interposed therebetween. There are disadvantages.

[0005] The building floor shown in the figure is a so-called indirect heat transfer system in which a soaking plate 9 is heated by a hot water pipe 4 and the heat of the soaking plate 9 is conducted to the surface floor plate 3. 3 has the disadvantage that it takes time to heat. In particular, when the surface floorboard 3 is made thicker, the heat transfer distance becomes longer,
There is an adverse effect of delaying the rise of floor warming. For this reason, the heating of the upper surface of the front floor panel 3 on a cold winter morning in which it is desired to heat quickly is considerably delayed. Actually, it takes more than 30 minutes to heat the surface temperature of the surface floorboard from 5 ° C to 30 ° C. Therefore, when floor heating is started, the whole room does not easily get warm,
It was necessary to use other heating appliances such as an air conditioner and a hot air fan heater together. This adverse effect can be reduced by making the surface floorboard thinner. However, when the surface floorboard is thinned, the floor strength is significantly reduced.

[0006] In recent years, especially in apartment houses, surface floorboards for floor heating which have both soundproofing properties have been required. For floors having poor soundproofing properties, for example, noise on the upper floor resonates greatly on the ceiling of the lower floor, and the living comfort of the lower floor is significantly deteriorated. In order to prevent this adverse effect, as shown in the cross-sectional view of FIG. 2, a building floor provided with a sound insulation layer 10 on the lower surface of the front floor plate 3 is also used. However, the heat conduction of the building floor is further deteriorated by the sound insulation layer 10, and the quick warming property of the surface floor panel 3 is further reduced. The quick warming property and the sound insulation property of the surface floor panel 3 are mutually contradictory properties, and it is extremely difficult to satisfy both.

[0007] Further, the building floor shown in FIGS. 1 and 2 has a floor warm panel 8 fixed between joists 7 and a surface floor panel 3 thereon.
The renovation of an existing building to make it a floor that can be heated is a very large-scale construction. This is because the existing floorboard is removed and the floor warm panel 8 is fixed. For this reason, the construction cost for providing a structure that allows floor heating by renovation further increases.

The present inventor has developed a building floor shown in a sectional view of FIG. 3 in order to solve such a problem. In this building floor, a surface floor plate 3 having a hot water pipe 4 built therein is fixed to an upper surface of a base floor 2 to which a control panel and the like are fixed. As this building floor incorporates a hot water pipe 4 in the surface floorboard 3,
There is no need to use warm floor panels. Therefore, the disadvantage of using the floor warming panel can be eliminated.

[0009] However, the building floor of this structure has a drawback that it takes a lot of time to incorporate the hot water pipe into the surface floor plate, and the manufacturing cost of the surface floor plate increases. Further, there is a disadvantage that the construction of the surface floorboard requires a considerable amount of time.
This is because it is necessary to connect the built-in hot water pipe so as not to leak while fixing the surface floor panel to the floor. Furthermore, this structure is extremely difficult to reliably prevent hot water pipes from leaking for a very long time. This is because the connecting portions of the hot water pipes become extremely large in order to connect the hot water pipes at the ends of all the surface floor boards.

[0010] To further complicate matters, repairing the heated floor of a building with this structure is extremely troublesome if the hot water pipe leaks water. This is because, in addition to the fact that it is extremely difficult to identify the leaking part, a part of the surface floorboard is removed to repair the connecting part of the leaking hot water pipe. When hot water leaks from the connecting portion of the hot water pipe, the leaked hot water leaks from a portion different from the water leaking portion to a ceiling or the like of a lower floor through a hot water pipe or the like. For this reason, the water leaking part on the lower floor is not always near the water leaking part of the hot water pipe, and often leaks at a considerably distant place.

Further, in the building floor shown in FIG. 3, since the hot water pipe 4 is built in the surface floor plate 3, it is difficult for the surface floor plate 3 to absorb the thermal distortion of the hot water pipe 4 and the like, There is a drawback that the surface floorboard 3 is apt to be damaged due to the resulting excessive force. In particular, when the surface floorboard is made of wood, there is a disadvantage that cracks and the like are easily generated and durability is poor. Durability is a very important property for floor-heated building floors. This is because it is extremely difficult to replace a damaged surface slab. In particular, since the replacement of the surface floor board incorporating the hot water pipe cannot be performed unless the connecting portion of the hot water pipe is removed, the replacement is extremely difficult, time-consuming, and extremely expensive. Also, even if you replace the surface floorboard, a new surface floorboard,
Old surface slabs have the drawback that surface conditions such as surface color are significantly different and cannot be repaired invisibly.

The present invention has been developed with the object of solving such drawbacks. An important object of the present invention is to provide a simple and easy construction at a low cost to achieve quick warming and sound insulation. It is an object of the present invention to provide a floor-heated building floor structure capable of having a structure excellent in performance.

Another important object of the present invention is that it can be remodeled at a low cost, can produce a large number of surface floor boards at a very low cost, is extremely durable, can minimize leakage of hot water, and can be easily manufactured. It is to provide a floor heated building floor structure that can be repaired.

The ground floor 2 has the ground plate 1 arranged and fixed on a plurality of joists 7 arranged horizontally and parallel to each other. The state where the base plate 1 is arranged on the joist 7
This is shown in the plan view of FIG. As shown in this figure, the base plate 1 includes a center base plate 1A provided at the center of the building floor for floor heating, and end base plates 1B provided on both sides of the center base plate 1A. .

The central base plate 1A is a rectangular flat plate having a flat surface. The central base plate 1A has, for example, a thickness of 2
A plywood of 0 mm can be used. Central base plate 1 shown in FIG.
A is a single large flat plate.
Can be arranged by connecting a plurality of flat plates.

As shown in the figure, the end base plate 1B is provided with two rows of grooves 11 bent in a U-shape on the surface. Two rows of grooves 1
1 has a structure in which an inner groove 11B having a small radius of curvature is provided in parallel with an inner groove 11A having a large radius of curvature. These grooves 11 are portions into which the curved portion of the hot water pipe 4 laid on the upper surface of the base plate 1 is inserted. Therefore, the depth and width of the groove 11 are designed to be larger than the outer diameter of the hot water pipe 4 inserted here. In particular, the width of the groove 11 is 1.2 to 8 times, preferably 2 to 5 times the outer diameter of the hot water pipe 4 so that the hot water pipe 4 can move in the groove even if it expands and contracts due to thermal expansion. Designed to.

The groove 11 provided in the end base plate 1B can be formed, for example, by laminating plate materials processed into a predetermined shape. In this method, an outer frame, a middle frame, and an inner frame cut into a predetermined shape are adhered to the upper surface of a rectangular lower plate to form outer grooves 11A and inner grooves 11B. The end base plate 1B formed in this manner has, for example, a thickness of the lower plate of 8
mm, the thickness of the outer frame, the middle frame, and the inner frame is 12 mm, and the thickness of the groove 1 having a depth of 12 mm is 20 mm.
1 can be easily provided. However, the groove provided in the end base plate may be provided by cutting a flat plate.

As shown in FIG. 6, the end base plate 1B having the above structure is provided on both sides of the center base plate 1A so that the opening edges of the U-shaped groove 11 face the center base plate 1A. Arrange the cards side by side. At this time, the end base plate 1B disposed opposite to both sides of the center base plate 1A is positioned at a position corresponding to １ ／ of the width of the end base plate 1B so that the outer groove 11A and the inner groove 11B face each other. Displaced. In this manner, the end base plate 1B allows the hot water pipe 4 laid on the upper surface of the base floor 2 to be continuous while meandering, as shown by the dashed line in FIG. Further, the base floor 2 shown in FIG. 6 has a structure in which a folded plate 1C is disposed at the lower right corner in the figure to make the hot water pipe 4 reciprocate. Further, a half-faced plate 1D obtained by dividing the end base plate 1B into two parts so as to be left-right symmetric is disposed at the upper left corner, and serves as a hot water supply part and a discharge part.

Further, the central base plate 1A, the end base plate 1B, the folded plate 1C, and the half-face plate 1D have a gap at the boundary where the adjacent base plates 1 play against thermal expansion without making the base plates 1 adjacent to each other adhere to each other. It is provided and arranged.

On the base floor 2, a heat insulating layer 5 is provided as shown in FIGS. The heat insulating layer 5 is preferably
On the upper surface of the base plate 1, a vibration isolator and a heat insulator are laminated and disposed. For the vibration insulator and the heat insulator, for example, plastic foam, foam rubber, non-woven fabric, etc. processed into a sheet,
Those obtained by hardening these into a board shape can be used. The vibration isolator absorbs vibrations on the floor and effectively prevents sound from leaking downstairs. The heat insulating material effectively prevents the heat of the hot water pipe 4 from being dissipated below the floor. The heat insulating layer 5 of this structure
The material and thickness of the anti-vibration material and the heat insulating material are optimally designed and laminated,
There is a feature that sound insulation and heat insulation can be reliably performed in an ideal state. However, the heat insulating layer does not necessarily need to have a structure in which both the vibration isolating material and the heat insulating material are laminated. As the heat insulating layer, a material having excellent vibration proof and heat insulating properties can be used alone.

The hot water pipe 4 is a flexible pipe made of, for example, a synthetic resin such as polypropylene or polyethylene. The hot water pipe 4 can be made of metal such as copper. The hot water pipe 4 has an outer diameter of about 10 mm
As shown by the one-dot chain line in FIG. 7, the pipes meander while making a U-curve on both sides of the base floor 2. The hot water pipe 4 has a curved portion formed in the groove 1 of the end base plate 1B.
1 and is curved U along this groove 11. Further, a hot water pipe 4 disposed on the central base plate 1A
Are arranged linearly so as to be parallel to each other.
As described above, the structure in which a single hot water pipe 4 is reciprocated for heating is characterized in that the hot water pipe 4 can be easily disposed and the floor surface can be uniformly heated. It is hot water supply,
This is because the average temperature of the circulating hot water can be balanced between the discharge side and the folded side of the hot water pipe 4.

As shown in FIG. 7, the hot water pipe 4 has one end connected to the hot water tank 12 and the other end connected to the circulation pump 13.
Is connected to the hot water tank 12. Hot water tank 1
Numeral 2 is provided with heating means (not shown) such as a heater or a burner, and stores hot water heated to an appropriate temperature. When the circulation pump 13 is driven, the hot water heated to an appropriate temperature in the hot water tank 12 circulates through the hot water pipe 4 to heat the building floor.

However, the structure of the building floor of the present invention is not necessarily required to have a structure in which one hot water pipe is reciprocated.
In the structure of the building floor of the present invention, as shown in FIG. 8, two hot water pipes 4 can be arranged in parallel while meandering. In this structure, a half-face plate is provided as a hot water supply and discharge unit without providing a folded plate on an end base plate at an end of the base floor. This structure is characterized in that the two warm water pipes 4 can efficiently heat the water, so that the quick warming property can be further enhanced. In addition, it is possible to uniformly heat the floor surface by making the supply direction of the hot water reverse as shown by the arrow in the figure.

The surface floor panel 3 is a floor panel disposed on the base panel 1. As shown in FIG. 7, the surface floor panel 3 is laid and fixed without any gap on the entire surface of the building floor on which floor heating is to be performed. Preferably, a teak flat plate is used for the surface floor plate 3. This is because the surface floorboard 3 made of teak is resistant to water, is less likely to be out of order due to shrinkage, cracks, and the like, and has an elegant appearance. However, the surface floorboard 3 can be made of wood other than teak.

As shown in FIGS. 4 and 9, the surface floorboard 3
A pipe groove 6 for housing the hot water pipe 4 is provided at the lower surface thereof. The width and depth of the pipe groove 6 are designed to be slightly larger than the outer diameter of the hot water pipe 4 so that the hot water pipe 4 can be inserted smoothly. The surface floor plate 3 is laminated and fixed on the upper surface of the heat insulating layer 5 in a state where the hot water pipe 4 arranged on the upper surface of the base floor 2 is inserted into the pipe groove 6. The surface floorboard 3 shown in the figure has two rows of pipe grooves 6 provided in parallel on the lower surface so that two hot water pipes 4 can be built therein. However, the surface floorboard can be provided with 1 to 4 pipe grooves by changing the width to various sizes.

Further, as shown in FIG. 5, the surface floor plate 3 disposed above the curved portion of the hot water pipe 4 does not necessarily need to have a pipe groove. This is because the curved portion of the hot water pipe 4 is inserted into the groove 11 of the end base plate 1B and does not protrude above the upper surface of the base plate 1. The surface floorboard 3 laid in this part has grooves 11 on the lower surface.
, And can be arranged separately from the central portion as shown in FIG. The surface floorboard 3 arranged in this way can be arranged with a different arrangement or material from the central part. However, the surface floor plate 3 disposed above the curved portion of the hot water pipe 4 does not necessarily need to be disposed separately from the central portion. The surface floorboard 3 is, as shown in FIG.
Those having the groove 11 on the lower surface can also be laid with the position of the joint shifted.

Further, as shown in FIGS. 4 and 9, the surface floor plate 3 is provided with a plurality of slit grooves 14 in parallel with the pipe grooves 6 opened on the lower surface. The slit groove 14 is provided around the opening of the pipe groove 6 so as to extend along the pipe groove 6. The slit grooves 14 shown in the figure are provided in two rows on both sides of the pipe groove 6. However, the slit groove may be provided only on one side of the pipe groove. The slit groove 14 has a feature that when the surface floor plate 3 is heated by the hot water pipe 4, the stress acting inside is dispersed and absorbed, and the deformation such as warpage or cracking can be effectively prevented.

However, in the structure of the building floor of the present invention, it is not always necessary to provide a slit groove in the surface floor plate. Although not shown, the surface floor plate may have a structure in which only the pipe groove is provided on the lower surface without providing the slit groove. In particular, the surface slab made of teak has a very small shrinkage and can disperse and absorb the stress acting inside only by the pipe groove. Furthermore, the surface floorboard is designed to be narrow,
The stress acting inside can also be absorbed by the connecting part of the surface floorboard.

Further, the surface floor plate 3 is provided with a connecting ridge 15 and a connecting groove 16 on the side surface. Surface floorboard 3 of this structure
When laying on the upper surface of the base floor 2, the connection protrusions 15 and the connection grooves 16 of the adjacent surface floor boards 3 are fitted and connected. The surface floorboards 3 connected in this manner have a feature that they can be laid on the surface of the boundary portion between the adjacent surface floorboards 3 without any step and with a good appearance.

The floor-heated building floor structure of the present invention is constructed as follows. [When Floor Heating is Performed on a Newly Built Building Floor] As shown in FIGS. 4 and 5, the base plate 1 is laid and fixed on the joist 7. As shown in FIG. 6, the base plate 1 has a center base plate 1A laid at the center, and end base plates 1 on both sides.
Lay and fix B. The end base plate 1B can be extended while meandering the hot water pipe 4 so that the center base plate 1A can be extended.
The end base plates 1B disposed opposite to each other are shifted from each other.

A heat insulating layer 5 is provided by laminating a vibration insulator and a heat insulating material on the upper surface of the base plate 1. If the vibration insulator or heat insulator is in sheet form, lay it so that it does not wrinkle or overlap. If the vibration insulator or the heat insulator is in the form of a plate, spread it so that there is no gap at the boundary. The laminated vibration insulator and heat insulator are fixed to the base plate 1 at predetermined intervals.

A cut for inserting the hot water pipe 4 is made in the heat insulating layer 5 laid on the upper surface of the groove 11 of the end base plate 1 B by a cutter or the like. The cut is provided along the center of the groove 11.

The hot water pipe 4 is disposed on the heat insulating layer 5 while meandering. The hot water pipe 4 provided on the central base plate 1A is provided so as to be linear and parallel. The hot water pipe 4 provided on the end base plate 1B is curved along the groove 11 and inserted into the groove 11.

The surface floor plate 3 is put on the hot water pipe 4 laid in a straight line. The surface floorboard 3 is a hot water pipe 4

The surface floor plate 3 is also placed on the curved portion of the hot water pipe 4.
In this way, the floorboard 3 is laid on the entire floor of the building to be heated. Further, the laid surface floor plate 3 is fixed to the base plate 1 with nails or the like.

One end of the hot water pipe 4 is connected to the hot water tank 12
And the other end is connected to the hot water tank 12 via the circulation pump 13.

[When Renovating Existing Building Floor by Applying Floor Heating] As shown in FIG. 10, a heat insulating layer 5 is provided on the upper surface of an existing floor plate 17 by laminating a vibration insulating material and a heat insulating material. The existing floor plate 17 is provided with the heat insulating layer 5 on its upper surface without being removed.

On the heat insulating layer 5, as shown by a dashed line in FIG. 7, the hot water pipe 4 is disposed to extend while meandering. The hot water pipe 4 provided at the center of the building floor is provided so as to be straight and parallel.

As shown in FIG. 10, the surface floor plate 3 is put on the hot water pipe 4 laid in a straight line. The surface floor plate 3 is covered with the hot water pipe 4 inserted in the pipe groove 6 of the surface floor plate 3. A thin surface floor plate 3 ′ such as a metal plate is placed on the curved portion of the hot water pipe 4 so that the upper surface of the surface floor plate 3 is flush with the upper surface. A thin surface floor plate 3 'such as a metal plate is provided with a sleeper 18 on the lower surface so that the hot water pipe 4 is not crushed. However, the curved part of the hot water pipe can be removed under the floor by removing a part of the existing floorboard. In this structure, the curved portion of the hot water pipe does not protrude above the upper surface of the existing floor plate, and therefore has a pipe groove on the lower surface without covering a thin surface floor plate such as a metal plate, or has no pipe groove. Surface floorboards can be laid.

In this way, the floorboard 3 is laid on the entire surface of the building floor to be heated. Further, the laid surface floorboard 3 is fixed to the existing floorboard 17 with nails or the like.

One end of the hot water pipe 4 is connected to the hot water tank 12
And the other end is connected to the hot water tank 12 via the circulation pump 13.
