Description

  The present invention relates to a temperature control mat for heating and cooling floors, walls, ceilings, and the like of a building room, a substrate for the same, and a construction structure of the temperature control mat.

  Hot water floor heating is known in which a temperature control mat in which a hot water pipe (heat radiating pipe) is routed in a groove on the upper surface of a plate-like substrate is laid on the floor surface.

  In this hot water floor heating, a temperature control mat (floor heating panel) in which a flexible synthetic resin pipe through which hot water passes is embedded in a piping groove of a substrate made of foamed synthetic resin or the like is used. This temperature control mat is laid on the floor of a building, and a surface covering material such as a carpet or a wooden decorative board is laid on the upper surface to constitute a heating floor. Hot water from a water heater is circulated in a resin pipe (heat radiating pipe) embedded in the substrate.

  Hot water from the above-described hot water heater is circulated to the heat radiating piping via a header incorporated in the peripheral edge of the substrate. The building hot water circulation pipe and the header are connected by a connecting pipe. It is not preferable that the connecting pipe is directly placed on the lower ground of the building floor or exposed on the floor surface. In view of this, a method has been adopted in which a connecting pipe guide panel is prepared and the connecting pipe is laid in a groove formed in the connecting pipe guide panel (Japanese Patent Laid-Open No. 2002-228168).

  The hot water circulation pipe protrudes into the room from the corner of the room floor or the lower part of the wall, but the position of the protrusion varies depending on the site. Therefore, there are various directions in which the connecting pipe connected to the header is pulled out from the temperature control mat.

  In Japanese Patent Laid-Open No. 2002-228168, a groove for burying a connecting pipe is provided on the upper surface of a connecting pipe guide panel that is adjacent to the temperature control mat and separate from the temperature control mat so as to be branched in a plurality of directions. .

  FIG. 7 is a plan view showing the piping structure of the connecting pipe guide panel of the publication. The connecting pipe guide panel 90 is abutted against the temperature control mat 80. The temperature control mat 80 is provided with a header arrangement space 81 and a heat radiation pipe groove 82 connected to the header arrangement space 81. The header arrangement space 81 faces a notched portion at one corner of the temperature control mat 80, and the header 83 is arranged in the space 81. A heat radiation pipe 84 is connected to the secondary side nozzle 83 b of the header 83, and is routed around the groove 82.

A connecting pipe (not shown) is connected to the primary side nozzle 83 a of the header 83. The connecting pipe is connected to the hot water circulation pipe on the building side through the grooves 91 and 92 or the grooves 93 and 94 of the connecting pipe groove 90. The connecting pipe grooves 91 and 92 extend linearly in the protruding direction of the nozzle 63a. The grooves 93 and 94 branch from the grooves 91 and 92 and extend in a direction orthogonal to the grooves 91 and 92 while being curved in an arc shape.
