Description

Description: TECHNICAL FIELD The present invention relates to a heat exchange type sheet, specifically, for a floor used for heating or cooling from a floor surface or a floor surface, for example, through a heat medium composed of a fluid such as hot water or cold water. Heat exchange type sheet for floors. More specifically, a woven cloth with coarse mesh is bent into a corrugated sheet to form a corrugated sheet, and watertight sheets are spread on the upper and lower sides of the sheet to form passages inside. Regarding the seat.

[Background technology]

A heat exchange type sheet for floors of this type constitutes a corrugated sheet with a filament bent in a corrugated shape and a filament crossing this filament as disclosed in JP-A-53-101738. A heat exchange type sheet is known in which a watertight sheet is spread on and the periphery is sealed. When this sheet is applied to heating or cooling by applying it to the floor surface or wall surface, a resin such as a resin is used as the watertight sheet. If polyester, polyolefin, or rubber such as chloroprene, butyl rubber, or polyurethane is used, a sharp object such as a stud may cause damage such as perforation and the fluid may leak from the flow path formed inside. There are not enough leak measures.

[Object of the Invention]

The present invention has been made in view of the above facts, and provides a heat exchange type sheet for a floor through which a heat medium composed of a fluid flows, which prevents damage such as perforation even with a sharp object such as a tack. .

[Disclosure of Invention]

This invention forms a corrugated sheet having a restoring force against the pressure in the vertical direction by bending a woven cloth woven by crossing filaments into a corrugated sheet, and the crossed filaments are formed into a binder sheet composed of the woven cloth. The woven fabric is woven and polymerized on the upper and lower sides of the corrugated sheet, and the woven fabric forming the binder sheet on the upper surface is embedded in the resin layer to form a cloth-containing resin layer. A sharp object is projected through the cloth-containing resin layer. Provided is a heat exchange type sheet for floors having a sealed peripheral edge, which is characterized in that a metal plate which is not attached is bonded.

The present invention will be described below with reference to the accompanying drawings. First
In the figure, reference numeral 1 constitutes a woven fabric 2 woven from filaments that cross each other. One of the filaments 1 forming the woven cloth 2 is bent in a corrugated shape to form a corrugated sheet 3 having a restoring force against the pressure in the vertical direction. The filament 1 constituting the corrugated sheet 3 is woven into a fine woven cloth 5 used as the binder sheet 4, and the woven cloth 5 is polymerized and integrated above and below the corrugated sheet 3.

The woven cloth 5 is embedded in a resin layer 7 lined with a metal plate 6 to form a cloth-containing resin layer 11, and the cloth-containing resin layer 11
The metal plate 6 is bonded to the corrugated sheet 3 by using the resin layer 7 as a bonding layer. Here, the metal plate 6 is limited to a metal plate that does not pierce a sharp object such as a tack. That is, when a sharp object is pierced, the heat medium passing through the internal flow path formed by the metal plate 6 and the corrugated sheet 3 leaks.

First, the woven fabric 2 forming the corrugated sheet 3 is made of polyester fiber, polyamide fiber, acrylic fiber, polyolefin fiber, or the like from the viewpoint that water resistance and resilience to external pressure are required. The woven fabric 5 constituting the woven fabric 5 is made of chemical fiber, natural fiber or the like in addition to the fibers of the same type as the corrugated sheet 3 in that restoring force is not required. A thin plate is enough to prevent sharp objects such as tacks from sticking, but thick plates are not excluded. The resin layer 7 is made of thermoplastic resin such as vinyl chloride resin, polypropylene, acrylic resin, and rubber such as chloroprene-butadiene which is equivalent to the resin here. The resin layer 7 covers the metal plate 6 by various methods such as laminating the metal plate 6 or adhering a sheet formed via an adhesive layer. To embed the woven cloth 5 constituting the binder sheet 4 in the resin layer 7 to form the cloth-containing resin layer 11, for example, the cloth is laminated on the woven cloth 5 to form a sheet as described above, and the sheet is bonded to the metal plate 6. Or a resin layer 7 backed by a metal plate 6
May be fused to the woven cloth 5. In addition, 8 is a seal formed on the periphery, 9 is an outlet of the fluid, and 10 is an inlet.

〔The invention's effect〕

That is, according to the present invention, the binder sheet 4 composed of the woven cloth 5 and the resin layer 7 in which the binder sheet 4 is embedded are provided.
The corrugated sheet 3 is formed on the woven cloth 5 of the resin layer 11 including cloth.
Since the corrugated sheet 3 does not separate from the resin layer 7 and the metal plate 6 is bonded to the resin layer 7, the metal plate 6 and the corrugated sheet 3 are securely integrated. It is. If the metal plate 6 and the corrugated sheet 7 are separated and disassembled, the restoring force of the corrugated sheet 3 with respect to the pressure in the vertical direction decreases, and as a result, it becomes impossible to secure the flow path through which the heat medium flows. Further, even if the heat exchange type sheet for floor is cut, the woven cloth 5 constituting the binder sheet 4 does not fray from the cut end. Moreover, since the sticking of sharp objects such as tacks is eliminated, the heat medium does not leak.
