Abstract

PROBLEM TO BE SOLVED: To obtain a woody warming mat being laid on the floor, e.g. the flooring of an existing housing, without damaging the basic tone of the floor by bonding longitudinal edge members tapered outward to the opposite ends in the grain direction of a coupling floor material. SOLUTION: A plurality of elongated woody pieces 2 of 12 mm thick, 75 mm wide and 2400 mm long, for example, are bonded in the lateral direction to constitute a coupling floor member 1 of fixed size and a hot water pipe 9 is arranged entirely on the rear side of the coupling floor member 1. Longitudinal edge members 3 tapered outward are fixed to the opposite ends in the grain direction (longitudinal direction) of the coupling floor material 1. Since the level difference (about 12 mm) between the floor surface and the woody warming mat is eliminated through the tapered part 8, the woody warming mat can be finished beautifully by fixing the longitudinal edge members 3 while eliminating the anxiety of tripping over the level difference.

[0010]

FIG. 1 is a plan view of an overlaid wooden heating mat (hereinafter, referred to as a wooden heating mat) of the present invention used in a hot water floor heating device.

This wooden heating mat has, for example, a thickness of 12 mm.
mm, width 75 mm, length 2400 mm length of wood piece 2
Are connected in the lateral direction to form a fixed-sized connecting flooring 1, and a hot water pipe 9 (FIG. 1)
(Middle and dashed lines). The wood piece 2 is a solid wood board having a length of about 100 to 800 mm joined and integrated in the longitudinal direction. The hot water pipe 9 is supplied with hot water from a heat source unit (not shown) and is circulated throughout the wooden heating mat.

A longitudinal edge member 3, which is tapered outward at both ends in the grain direction (longitudinal direction) of the connecting floor member 1,
3 is attached.

FIG. 2 is a sectional view taken along the line A--A showing the internal structure of the wooden heating mat shown in FIG. According to FIG. 2, the plurality of wood pieces 2 and the longitudinal side surfaces of the longitudinal edges 3 at both ends thereof are unevenly processed, and these wood pieces 2 and the wood pieces 2 and the longitudinal edges 3 are mutually attached. Uneven fitting (song joint)
In addition, a flexible backing material 6 formed by bonding an aluminum sheet 4 for heat equalization and a nonwoven fabric 5 to the back side of the connecting floor material 1 is bonded to each of the wood pieces 2 and the vertical edge material. 4
Are linked.

Further, as shown in the figure, a concave groove 7 is formed on the back surface of each piece of wood 2, and the hot water pipe 9 made of cross-linked polyethylene is embedded in the concave groove 7. Therefore, the wooden heating mat can be folded by a tongue joint structure of a plurality of elongated plate pieces and a connecting structure by a flexible backing material 6 for fastening the tongue jointed wood pieces 2 respectively. Become. FIG. 7 shows a folded state of the wooden heating mat at the time of packing or storage, wherein 10 is an attached side edge material, and 11 is a corner material.

The vertical edge member 3 has a tapered shape toward the outside, and the tapered portion 8 causes a step (about 12 mm) between the floor surface and the laid wooden heating mat.
Therefore, by attaching the vertical edge material 3, the finish when the wooden heating mat is laid can be made beautiful, and further, there is no worry that the foot can be taken off by the step. In addition, since the hot water pipe 9 is not buried in the vertical edge member 3, it can be easily separated from the connecting flooring 1 (separation is difficult if the hot water pipe 9 is buried).
That is, as described above, the vertical edge member 3 and the wood piece 2 adjacent thereto are joined by the tongue joint on the opposite side surface and the back surface member 6 (the aluminum sheet 4 and the nonwoven fabric 5) adhered to the back surface. Therefore, the vertical edge member 3 can be easily separated by cutting the rear member 6 along the tongue joint from the rear surface side of the connecting floor member 1 using a cutter or the like (see FIG. 3). Since the aluminum sheet 4 and the nonwoven fabric 5 constituting the back material 6 are both extremely thin, they can be easily cut by a cutter. As described above, if the installer can easily remove the vertical edge material 3 with one cutter, a wooden heating mat can be newly expanded (extended), or as shown in FIG. ) Can be installed very easily to lay the entire floor and make the whole room have a unified flooring finish. Of course, the wood heating mat or dummy material 14
Also has a tongue-and-groove structure by fitting in the concave and convex like the main body.

FIG. 5 (a) shows a lateral edge material 1 tapered outward at both ends of the connecting floor material 1 which is perpendicular to the plate.
It shows a state where 0 and 10 are combined. As shown in the cross-sectional view taken along the line BB of FIG. 5B, the horizontal edge material 10 is spliced by uneven fitting with the wood piece 2 (short side) as in the case of the vertical edge material 3. This is a structure attached together with the wood heating mat together with the tapered corner members 11 arranged at the four corners (see FIG. 6). In addition,
Reference numeral 12 denotes a hot water connection port to which an outgoing / returning hot water pipe 13 is connected. The other end of the hot water pipe 13 is installed outside via a hot water outlet (not shown) attached to an indoor wall or the like. Is connected to the piping.

As described above, the lateral edge members 10 are fitted in the lateral direction of the connecting floor material 1, that is, in the connecting direction of the wooden pieces 2 by uneven fitting.
By combining the two, the horizontality of the entire connection flooring 1 is improved,
In addition, it is possible to suppress the warpage and bending of the wooden piece 3 due to heating heat or the like, and it is possible to realize stable laying without generating a gap between the wooden piece 3 and the floor surface.

Of course, the horizontal edge material 10 is the same as the vertical edge material 3 described above.
In the same manner as described above, the taper processing eliminates a step with the floor surface, and makes the finish after construction beautiful.

The above-mentioned vertical edge member 3, horizontal edge member 10 and corner member 11 are respectively provided with fixing brackets 15, 1 shown in FIG.
5, the screws are fixed to each other.

[0020]

As described above, according to the first aspect of the present invention, the connecting floor member is formed by connecting the longitudinal edges tapered outward to both ends in the grain direction of the connecting floor member. Therefore, the step between the floor surface and the wooden heating mat at the time of construction of the wooden heating mat can be eliminated, so that the finish can be beautiful and the inconvenience of taking steps off the steps can also be prevented.

According to the present invention described in claim 2,
Because it is a structure that does not bury the hot water pipe in the vertical edge material,
By cutting the back surface material with a cutter or the like, the vertical edge material can be easily removed. Therefore, flooring finishing can be easily performed by expanding (adding) a wooden heating mat or laying dummy materials.

Further, according to the present invention as set forth in claims 3 and 4, since a lateral edge material is connected to both ends of the connecting floor material which are perpendicular to the grain, the connection is achieved by attaching the horizontal edge material. The horizontality of the entire flooring material is improved, and the warpage and bending of the wood piece due to heating heat or the like can be suppressed. In particular, the connection between the connecting floor material and the lateral edge material is a tongue-and-groove structure by fitting unevenness, so that the connection is easy, and the horizontality of the connecting floor material is more reliably ensured. Stable laying with no gap between them can be realized.
