Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a heating floor panel and a heating floor structure.

[0002]

2. Description of the Related Art As a heating floor structure, Japanese Patent Laid-Open Publication No.
Japanese Unexamined Patent Publication No. 4 (KOKAI) No. 4 is conventionally known. In this heating floor structure, a wooden base panel formed by arranging and fixing a plurality of band-shaped plates on the upper surface of a flat plate in parallel at predetermined intervals so as to be parallel to the joists, over a plurality of joists. Along with being installed, a heat insulating material is interposed between adjacent joists and joined to the lower surface of the base panel, and a hot water flow pipe is housed between adjacent strips of the base panel, and on the upper surface of the base panel, A plurality of wooden floors are laid via metal plates.

[0003]

However, the above-mentioned conventional heating floor structure has the following problems.

[0004] That is, it is very troublesome to sequentially apply each floor material as described above at a building site, and the work efficiency is remarkably inferior.

[0005] Further, during the work of disposing the hot water distribution pipes, dust may be accumulated between the strips on the upper surface of the base panel, or the same portion may be damaged. Moreover,
Since the hot water distribution pipes arranged between the strips on the upper surface of the base panel are exposed, they may be damaged during the subsequent work. Furthermore, the installed base panel serves as a scaffold during the subsequent work, but since the base plate strips are arranged so as to be parallel to the joists, particularly between adjacent strips in the same panel. The strength of the part was not enough. Therefore, in order to cope with such a problem, when constructing the above-mentioned conventional heating floor, even if it is troublesome, a plywood having a thickness of about 12 mm is discarded and pasted on the installed base panel. Was being done. In addition, if such thick plywood is used as a discarded material, the temperature rise during floor heating will be slow, and the floor surface will be high. In some cases, the scaffolding became too high, making it difficult to perform construction.

The metal plate interposed between the base panel and the wooden flooring contributes to the improvement of the heat uniformity. For example, a 0.35 mm or 0.6 mm thick zinc iron plate or aluminum plate is used. I was This metal plate is usually fixed to the base panel together with the wooden floor by nails that are driven into the real part of the wooden floor from diagonally from above.However, the nails are slid and driven into the metal plate because they are harder and more smooth than wooden floors It was difficult. Also, due to the difference in hardness between the wooden floor and the metal plate, when the nails driven into them reach the metal plate, they decelerate momentarily, and the wooden floor rises toward the nail head due to the reaction, and the nail is driven as it is. In some cases, the wooden flooring was raised from the base panel.

A joist is installed on a floor substrate such as a concrete slab, and a joist is installed over a plurality of bridges supported by a floor bundle erected on a solid foundation or slab. However, the latter case has the following problems. That is, as a material of joist and daiki,
It is preferable to use wood that has been dried to a water content close to or lower than the equilibrium moisture content of Japan (about 14 to 16%). The water content decreases to approach the rate. In particular, in the case of a joist or an oversize building that forms a heating floor, drying shrinkage is likely to occur under the influence of heat generated by floor heating. In addition, there is a case where the slabs and the like below the bed bundle supporting the pulling settle down unequally and the bed bundles rise from the slab stones and the like. When such joist and heavy pulling dry shrinkage and the rise of the floor bundle occur, the floor surface level may be degraded or floor noise may occur during walking.

[0008] An object of the present invention is to solve the above problems.

[0009]

A heating floor panel according to the present invention comprises a plurality of cross-bars and adjacent cross-bars arranged in parallel at predetermined intervals on the lower surface of a wooden board in which a hot water flow pipe is built. The lower panel unit made of a heat insulating material interposed therebetween is joined.

[0010] In the heating floor panel of the present invention, the wooden board having the hot water flow pipe therein is, for example, a wood board in which an upper plate and a lower plate having a groove in which the hot water flow pipe is accommodated on the upper surface are joined. is there. In this case, it is preferable that the metal sheet is disposed and fixed at at least one of the upper surface, the lower surface, and the middle portion of the thickness of the wooden board and the upper surface of the lower board.

In the heating floor panel of the present invention,
Since the wooden board and the lower panel unit are bonded to each other while being shifted from each other, an overhang for adjacent panel bonding or a cutout portion to be fitted with the overhang is formed on at least one of the four sides. Is preferred.

[0012] In the heating floor structure according to the present invention, a plurality of the heating floor panels are installed over a plurality of pulleys supported by a height-adjustable floor bundle, and a floor is provided on the upper surface of these panels. Finishing materials are laid.

[0013]

Next, embodiments of the present invention will be described with reference to the drawings.

1 to 4 show the structure of a heating floor panel according to the present invention. The heating floor panel (1) is provided on a lower surface of a wooden board (2) in which a hot water distribution pipe (3) is incorporated, with a plurality of crosspieces (5) and adjacent crosspieces arranged in parallel at a predetermined interval. (5) A lower panel unit (4) made of a heat insulating material (6) interposed between them is joined.

Wood board (2) with a built-in hot water distribution pipe (3)
As shown in FIG. 2, an upper plate (21) and a lower plate (22) having a groove (7) in which a hot water flow pipe (3) is accommodated on the upper surface are joined.

As shown in FIG. 2, a metal sheet (8) is arranged and fixed on the lower surface of the upper plate (21) of the wooden board (2).

On the upper part of the four sides of the panel (1), a wooden board (2)
The lower panel unit (4) and the lower panel unit (4) are shifted from each other to form a projection (9) or a cutout (10) fitted with the projection (9).

The material of the lower board (22) of the wood board (2) is plywood, wood fiber board such as medium fiber board (MDF) or hard fiber board (HB), particle board, oriented strand board, laminated board. And wood materials such as glued laminated wood, and a single type may be used, or a combination of several types may be used. In addition, dimensional stability, that is, from the viewpoint that the dimensional change due to moisture absorption and desorption is small, plywood is preferable as the material of the lower plate (22),
In terms of workability and homogeneity, wood fiberboard is preferred. The thickness of the lower plate (22) is determined by the groove (7) formed on the upper surface of the lower plate (22).
Must be thicker than the depth of the
The strength is set in consideration of the strength of the wooden board (2) and the strength of the entire panel (1).

Examples of the material for the hot water distribution pipe (3) include:
Examples thereof include pipes made of metal such as copper and iron, and pipes made of synthetic resin such as cross-linked polyethylene resin. However, from the viewpoint of the connectivity between the pipes, a pipe made of a crosslinked polyethylene resin which is rich in flexibility and can be easily connected by, for example, a bamboo shoot joint and a pipe band is preferable.

The grooves (7) on the upper surface of the lower plate (22) are appropriately formed according to the size, number and piping pattern of the hot water flow pipes (3) to be accommodated. When a flexible pipe such as a cross-linked polyethylene resin pipe is used as the hot water flow pipe (3), the depth and width of the groove (7) for accommodating the pipe depend on the flow of the hot water flow pipe (3). In consideration of the radial and longitudinal expansion, it is set to be slightly larger (about 0.2 mm in depth and about 0.5 mm in width) than the outside diameter of the hot water flow pipe (3) when water is not flowing. You. Connect both ends of the hot water distribution pipe (3) to adjacent panels (1)
Both ends of the groove (7) on the upper surface of the lower plate (22) are open to the side surface for connection with the end of the hot water flow pipe (3). The width of both ends of the groove (7) in which the both ends of the hot water flow pipe (3) are accommodated is made larger than the above-mentioned groove width in order to facilitate the connection work of the hot water flow pipe (3). (See FIG. 4). As shown in FIGS. 1 and 3, the hot water flow pipe (3) is normally arranged in a meandering shape when viewed from a plane. In this case, as shown in FIG. The groove (7) where the (31) is accommodated is perpendicular to the crosspiece (5), which reduces the bending deflection of the wooden board (2) due to walking load, etc., and thus the entire panel (1). It is preferable because it can be performed. In the panel (1) shown in FIGS. 1 and 3,
The hot water distribution pipe (3) is piped slightly skewed to one short side of the wood board (2), and the pipe position is appropriately set according to the position of the panel occupying the heating floor. Yes, there is a panel in which a hot water distribution pipe (3) is piped almost all over the wooden board (2), but it is further biased to one shorter side than the wooden board (2) shown in FIGS. There is also a panel in which a hot water distribution pipe (3) is piped to one long side.

The upper board (21) of the wood board (2) is a hot water flow pipe (3).
And serves to protect the groove (7) on the upper surface of the lower plate (22) in which the pipe is housed, and is formed of the same material as the lower plate (22). Good. Upper plate (2
The thickness of 1) should be thinner in consideration of heat conduction from the hot water flowing through the hot water flow pipe (3) to the floor, and in general the lower plate
Although it is made thinner than (22), it is necessary to take care that local load on the hot water distribution pipe (3) built in the wooden board (2) does not act during construction, so it is preferably 2.5 mm or more. ,
More preferably 3 mm or more, still more preferably 3.5 m
m or more. However, when the metal sheet (8) is arranged at a predetermined position on the wooden board, the thickness of the upper board (21) may be smaller than the above in consideration of the thickness and strength of the metal sheet (8). There is.

As shown in FIG. 4, the lower plate of the upper plate (21)
(22) At the locations corresponding to both ends of the groove (7) on the top surface,
A notch (11) having a width slightly wider than the width is formed, and a detachable lid (12) is fitted in the notch (11). By removing the lid (12) fitted in the notch (11), both ends of the hot water flow pipe (3) can be exposed. For example, using a bamboo shoot joint (13) and a pipe band (not shown) Connection work can be performed easily.
When the connection of the hot water distribution pipe (3) is completed, the lid (12) is again cut out.
(11), the both ends of the hot water flow pipe (3) are covered, and there is no possibility that the hot water flow pipe (3) will be damaged during the subsequent work. The lid (12) described above
May be formed from a completely different material from the upper plate (21),
If the plate piece generated when the predetermined portion of the upper plate (21) is punched to form the cutout (11) is used as it is as the lid (12), both can be formed at the same time, and the material can be formed. It is preferable because it can be used effectively.

The metal sheet (8) contributes to the improvement of the heat uniformity, and an aluminum sheet or an iron sheet having a thickness of 0.3 mm or less is usually used. If the thickness of the metal sheet (8) exceeds 0.3 mm, the heat uniformity will be further improved, but the weight of the panel (1) will increase and the penetration of nails for stopping floor finishing materials will decrease. In addition, when it is necessary to cut a part of the panel (1) at a construction site, the cutting operation becomes difficult, and the cutting saw or circular saw blade becomes worn out. The thickness of the metal sheet (8) is
In consideration of workability such as bonding work with (2), handling work, etc., heat uniformity and penetration of nails, the thickness is preferably in the range of 0.04 mm to 1 mm. The metal sheet (8) is disposed and fixed on the lower surface of the upper plate (21) in the panel (1) shown in FIG. 2, but the upper surface of the upper plate (21) and the middle part of the thickness of the upper plate (21) ( (One or more places), the upper surface of the lower plate (22) (including the groove (7)) or a plurality of these places. However, in terms of the soaking effect, the upper plate (2) that can come into contact with the hot water flow pipe (3)
It is preferable to be arranged and fixed on the lower surface of 1) and / or the upper surface of the lower plate (22), and it is auxiliaryly arranged and fixed in other places. The metal sheet (8) is fixed to the lower surface of the upper plate (21), the upper surface of the lower plate (22), etc., which are adjacent to the metal sheet (8), usually by bonding. Therefore, the metal sheet (8) does not move when the nails for stopping the floor finishing material are driven into the panel (1) from diagonally above, and the floor finishing material does not fit in a raised state. Also, even when it is necessary to cut a part of the panel (1), the cutting work is easier than cutting the metal plate alone because the metal sheet (8) is integrated with other panel materials. The hand and fingers are not cut by the metal sheet (8) during handling.

The thickness of the wooden board (2) depends on the panel (1)
In consideration of the fact that it will be used as a scaffold for subsequent construction work, the thickness of 12 m
What is necessary is just to set suitably so that the intensity | strength equivalent to the plywood of about m may be obtained. At that time, a groove formed on the upper surface of the lower plate (22)
It is necessary to determine the thickness of each constituent material such as the upper plate (21) and the lower plate (22) in consideration of the dimensions and arrangement of (7). For example, upper plate (21)
The groove (7) formed on the upper surface has a width of 9 mm and a depth of 8.7 m
m, pitch 112mm, the thickness of wood board (2) is 14
It may be about 15 mm. The vertical and horizontal dimensions of the wooden board (2) are determined according to the module that serves as a reference for setting the longitudinal dimension of the house.

As the material of the crosspiece (5), for example, lumber of wood, laminated wood, laminated veneer or structural lumber, laminated wood for structure,
Laminated materials for structural veneers and the like, in particular, laminated timber for structural use,
Structural veneer laminates are stable in strength and are manufactured to be below the equilibrium moisture content of Japan (14-16%), and shrinkage during floor heating is small. ) Is desirable. The cross-sectional dimension of the bar (5) is generally 45 mm square, but the width is narrower than 45 mm and the thickness is 45 mm.
mm or more than 45 mm depending on the thickness of the heat insulating material (6). Pier (5)
As a means for joining to the lower surface of the wooden board (2), bonding with an adhesive, nailing with nails such as nails, screw nails, wood screws, screws or the like, or a combination thereof may be used. The distance between adjacent bars (5) is generally about 303 mm, but may be smaller. When the thickness of the wooden board (2) is large, it may be wider than 303 mm. The groove parallel to the crosspiece (5) on the lower surface of the wooden board (2)
(7) A portion corresponding to the portion, for example, the panel (1) shown in FIG.
A reinforcing bar may be arranged and fixed at three positions at the left end of the bar at right angles to the bar (5).

The material of the heat insulating material (6) is a known material usually used as a heat insulating material such as polystyrene foam (by the bead method or extrusion method), polystyrene foam, rigid urethane foam, phenol foam and the like, and glass wool. Can be appropriately selected from the above materials. The thickness of the heat insulating material (6) may be slightly (about 1 to 4 mm) thinner than the thickness of the bar (5) as shown in FIGS. This was done to prevent damage to the insulation (6) when handling the panel (1). Of course, the thickness of the heat insulating material (6) may be the same as the thickness of the crosspiece (5). When the panel (1) is installed on a concrete slab or a flat base (disposable plywood or particle board), the thickness of the heat insulating material (6) must be adjusted to For example, the thickness may be about 2 to 4 mm thicker than the thickness.

The vertical and horizontal dimensions of the wooden board (2) are usually
The dimensions of the lower panel unit (4) made of the heat insulating material (6) are almost the same as the vertical and horizontal dimensions. In the panel (1) shown in FIG. 1, the wood board (2) and the lower panel unit (4) are shifted both vertically and horizontally, so that the panel (1) has one of the upper portions of the pair of long sides. Overhang for joining adjacent panels
(9) has a notch (10) for panel joining on the other side, and an overhang (9) for joining adjacent panels on one side of one of the pair of short sides of the panel (1). A panel joining notch (10) is formed. These overhangs (9) and notches (10) need not necessarily be formed on all four sides of the panel (1), but need only be formed on at least the sides in contact with adjacent panels. That is, the side on which the overhang portion (9) or the notch portion (10) in the plurality of panels (1) constituting the heating floor is to be formed is determined according to the arrangement of each panel (1). If the wood board (2) and the lower panel unit (4) have the same vertical and horizontal dimensions, the panel joining overhang (9)
And the notch (10) must be all four sides or two parallel to each other.
Formed on the side, the wooden board (2) and the lower panel unit
By providing a difference in the vertical, horizontal or vertical and horizontal dimensions from (4), only one or three of the four sides of the panel (1) have a panel joining overhang (9) or a notch (10). It is also possible to form Positioning between two adjacent panels (1) can be easily performed simply by fitting the overhanging portion (9) of one panel (1) into the notch (10) of the other panel (1). The panels (1) are joined together by, for example, bonding the upper and lower opposing surfaces of the overhang (9) and the notch (10) with an adhesive, or the overhang (9) fitted into the notch (10). It can be easily performed by driving in nails from above, or by using both together. By adjoining the adjacent panels (1) in this manner, the upper surfaces of the panels (1) are flush with each other, making it difficult for a gap to be formed between the panels (1), From the viewpoint of the present invention, a floor structure that is the same as the conventional floor structure in which a discarded material is constructed on a single joist can be obtained. In the two panels (1) joined to each other, a slight gap is formed between at least one of the upper wooden boards (2) and between the lower panel units (4). This is preferable in that even if there is a variation in joining between the wooden board (2) and the lower panel unit (4), it can be absorbed. The vertical and horizontal dimensions of the panel (1) correspond to the dimensions of the housing module.

The heating floor panel (1) according to the present invention comprises:
There are a case where it is installed directly or through a cushion sheet on a flat foundation made of a concrete slab or a wooden board, and a case where it is installed over a plurality of sculptures. In the former case, the panel (1) is fixed to a concrete slab or the like by fastening with nails, bonding with an adhesive, or using both together. Also, the panel (1) may be placed on a flat base. The latter case will be described in detail below.

And a cylindrical turnbuckle (45) having female threads at both ends. A fixing nut (46) and a spring washer (47) are fitted into the two screw rods (42, 44). This floor bundle
The height of (40) can be adjusted by rotating the turnbuckle (45) in a required direction. Each component of the floor bundle (40) is usually made of metal such as steel, but some or all of the components may be made of synthetic resin. Although the pedestal (41) is shown in FIG. 5 as a flat plate, it may be, for example, one having legs or the like, that is, stably mounted on a floor base. If it is, there is no particular limitation. Also, the first screw rod (41) is attached to the pedestal (41).
Forming a downwardly protruding receiving portion into which the lower end of the

The seat (43) is fixed to the bar (14) by, for example, nailing with nails such as nails and screw screws, bonding with an adhesive, or a combination thereof.

As the floor finishing material (15), any known materials such as wood flooring, carpet, cork, cushion floor and the like may be used, and the construction may be performed by a known method. However, when the floor covering (15) is fixed to the panel (1) with nails or staples, care must be taken to avoid the hot water flow pipe (3) in the panel (1). When a plurality of floor finishing materials (15) are used, such as wood flooring, care must be taken so that the seams of the floor finishing materials (15) do not coincide with the seams of the panels (1).

Next, the steps of constructing the heating floor structure will be described with reference to FIGS.
This will be described with reference to FIG. First, the floor bundle (4) is placed on the floor base (16).
A plurality of pullers (14) are installed via (0). Although not shown, the floor bundles (40) are L-shaped
They are arranged so that the direction of (43) is alternately left and right with respect to the bargain (14).

Next, as shown in FIG. 6, the heating floor panel (1) extends over a plurality (typically two)

[0036]

According to the heating floor panel of the present invention, the heating floor structure can be easily constructed simply by installing the floor panel on a floor base or a plurality of bridges and laying a floor finishing material thereon. As a result, the workability is significantly improved as compared with the related art at the beginning. In addition, since the hot water distribution pipe is pre-installed in the wooden board of the panel, there is no danger of damaging the hot water distribution pipe at the time of construction or collecting garbage in the place where it is stored, and there is no need to discard it. is there.

If a metal sheet is arranged and fixed at the above-mentioned predetermined position in the wood board of the panel, the heat uniformity can be improved, and it is easy to drive a nail for stopping the floor finishing material.

Further, since the wooden board and the lower panel unit are bonded to each other while being displaced from each other, a projection for adjoining the adjacent panel or a cutout to be fitted with the projection is provided above at least one of the four sides. If formed, the positioning and joining of adjacent panels can be easily performed, and therefore, even when drying and shrinkage of the wooden board or the crosspiece accompanying floor heating occurs, the gap between the panels is difficult to expand, and as a result, Accordingly, the spread of the gap between the floor finishing materials can be reduced.

According to the heating floor structure of the present invention, it is possible to adjust the floor level by appropriately adjusting the height of the floor bundle even when the floor heating causes the floor heating or the drying shrinkage of the crosspiece. It can also prevent floor noise.
