[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.
The connecting pipe guide mat according to the present invention is a dummy mat at the same time as arranging and fixing the connecting pipe connecting the header section and the heat medium control section arranged on the peripheral portion of the plate-like body constituting the floor heating mat. It also fulfills the function of The mat for guide pipes is based on a plate-like body having substantially the same thickness as the floor heating mat laid at the same time. The size and planar shape of the substrate can be appropriately determined according to the place where the substrate is laid.

[0009] The material of the base of the mat for guide pipes can be appropriately selected according to the place where the mat is laid.
For example, when laying a connecting pipe guide mat near the side wall in a room where furniture and other furniture are placed, the base is prepared from a relatively rigid tree so as to withstand the weight of the furniture. Is preferred. When the connecting pipe guide mat is laid in the vicinity of a foam synthetic resin floor heating mat, a floor is provided so that when a person walks on the mat, the same stepping feeling as the floor heating mat is given. It is preferable to prepare the base with a foamed synthetic resin of the same type as the heating mat.

The foamed synthetic resin may be either a foamed hard resin or a foamed soft resin. Examples of the foamed hard resin include foamed hard polyurethane, foamed polystyrene, foamed crosslinked polyethylene, a mixture of foamed polystyrene and foamed polyethylene, foamed polypropylene, foamed polyvinyl chloride, foamed crosslinked rubber, and the like. Examples of the foamed soft resin include foamed non-crosslinked polyethylene, foamed polyvinyl acetate, and foamed non-crosslinked rubber. The expansion ratio of the foamed synthetic resin can be appropriately changed depending on the type of the synthetic resin and the thickness of the base, and can be about 2 to 100 times.

One surface of the base of the connecting pipe guide mat has substantially the same width and substantially the same depth as the outer diameter of the connecting pipe, and has a U-shaped cross section when cut at right angles in the longitudinal direction. Grooves are engraved. This groove functions to bury the connecting pipe. The reason why the width and depth of the groove are substantially the same as the outer diameter of the connecting pipe is to bury the connecting pipe in the groove as closely as possible to make it difficult to remove.

An adhesive layer is provided on the other surface of the base of the mat for guide tube guide (hereinafter referred to as "back side of base"). The adhesive layer functions to fix the connecting pipe guide mat to the base surface. It is preferable that a part of the adhesive layer is constituted by a solventless adhesive. This solventless adhesive is used to permanently fix the connecting pipe guide mat to the base surface. Here, the term "finally fixed" means that when the mat for connecting pipe guide is fixed to the base surface, it is not peeled off, for example, until reforming.

The thickness of the non-solvent type adhesive layer can be appropriately determined according to the kind of the adhesive, the application method, the surface condition of the base surface, and the like, and is, for example, about 0.01 mm to 3 mm. it can. The solventless adhesive is applied to the back surface of the base in a linear or dotted shape as described later, but the base is pressed against the base floor in order to fully fix the connecting pipe guide mat to the base floor. Then, the adhesive spreads from the applied portion to the periphery and becomes thin, and finally, the thickness of the solventless adhesive layer becomes extremely thin.

As the non-solvent type adhesive, those which are generally used can be used without any limitation. For example, silicon-based, polysulfide-based, and urethane-based adhesives as described in JP-A-4-312671 can be used. And an epoxy-based non-solvent type adhesive. The non-solvent type adhesive is applied on the back side of the base of the communication pipe guide mat at the site when fixing the communication pipe guide mat to the base surface. When the adhesive is applied to the back surface of the base, it is not necessary to apply the adhesive to the entire back surface, and the adhesive can be applied linearly or in a dot form in the range of 5% to 95% of the area of the entire back surface. In this range, about 40% to 60% is preferable.

A double-sided pressure-sensitive adhesive tape can be attached to a portion of the adhesive layer where the above-mentioned solventless adhesive is not applied. The double-sided pressure-sensitive adhesive tape is used to temporarily fix the communication tube guide mat to the base surface. Here, "temporarily fixed"
This means that the connecting pipe guide mat is temporarily fixed to an appropriate place on the lower ground, and when finely adjusting the position of the connecting pipe guide mat, it means a fixed state that can be easily peeled off. According to the double-sided adhesive tape, the connecting pipe guide mat can be extremely easily fixed to the base surface, and even once fixed, it can be relatively easily peeled off and fixed again.

The double-sided pressure-sensitive adhesive tape may be selected from commercially available products that fulfill the above functions, and its thickness can be appropriately determined according to the type of the pressure-sensitive adhesive tape and the surface condition of the base surface. For example, it can be about 0.01 mm to 3 mm. The adhesive of the double-sided adhesive tape is J
It is preferable to use one having a peeling adhesive strength of 100 g or more in a 90 ° peeling method test based on IS Z 0237.

One side of the double-sided pressure-sensitive adhesive tape may be previously adhered to the back surface of the base of the mat for guide tube or may be adhered on site. At this time, the other surface of the double-sided pressure-sensitive adhesive tape is protected with a release film or release paper, and is peeled off immediately before sticking to the base surface. The attachment position and distribution mode of the double-sided pressure-sensitive adhesive tape on the back surface of the base can be appropriately determined in consideration of the application mode of the solventless adhesive. For example, (1) a mode in which a pair of opposed ends of the back surface of the substrate are linearly arranged in parallel with each other (see FIG. 5 described later), or (2) a unit made into small pieces can be arbitrarily added to the back surface of the substrate. And the like, which are distributed in the form of dots.

A thin plate can be interposed between the base of the mat for guide tube and the adhesive layer. When the base of the connecting pipe guide mat is made of a foamed synthetic resin, the thin plate serves to reinforce the base to increase the rigidity of the entire connecting pipe guide mat, and to provide the connecting pipe guide mat. Performs a function of preventing the substrate from being eroded by the adhesive layer. This thin plate can be prepared from a synthetic resin, metal, rubber, nonwoven fabric, or the like, and can be adhered to the back surface of the base of the connecting pipe guide mat with an adhesive or the like. The thin plate is preferably prepared from a synthetic resin, and a film made of polyethylene terephthalate is particularly preferable. The thickness of the thin plate can be appropriately determined according to the type of the thin plate itself, the substrate, and the type of the adhesive.
It can be about 3 mm.

The following procedure can be used to construct a heatable floor using the connecting pipe guide mat according to the present invention. First, (1) a floor heating mat is laid at a predetermined place in a room. Next, (2) a connecting pipe guide mat is disposed and temporarily fixed between the header and the heat medium control unit disposed on the peripheral portion of the plate-like body constituting the floor heating mat, and then the connecting pipe is connected to the heating pipe. The connecting pipe is buried in the groove formed on the upper surface of the guide mat, and the position of the connecting pipe guide mat is finely adjusted and determined, and then fixed to the base surface by pressure bonding. continue,
(3) Dummy mats are laid on parts other than the floor heating mat and the connecting pipe guide mat, and these floor heating mats,
A surface covering material is laid on the upper surface of the connecting pipe guide mat and the dummy mat to form a heatable floor.

When a floor which can be heated is formed by the above-described procedure, it is preferable to bury the connecting pipe in the groove of the connecting pipe guide mat and then cover the upper surface thereof with a flexible thin plate. The flexible thin plate prevents the connecting pipe from jumping out of the groove to the outside. The type of the flexible thin plate may be any type as long as it fulfills the above-mentioned functions. For example, various types of commercially available tapes, aluminum foil for improving heat radiation performance, tin foil, and metal foil such as stainless steel foil may be used. Can be mentioned. Among them, an aluminum foil is preferred from the viewpoints of ease of production and cost. Examples of the surface covering material that covers the upper surfaces of the floor heating mat, the communication pipe guide mat, and the dummy mat include a carpet and a wooden plate.
