Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an auxiliary member for laying a heat medium conduit (communication conduit or communication tube). More specifically, a wide dummy plate is used when a heating medium conduit connecting the header part of the floor heating mat (or heat radiating plate) and the header part connected to the heating medium control part is arranged and fixed on the floor surface. The present invention relates to an auxiliary member for laying a heat transfer medium conduit that can be used as a barrier-free floor surface that does not easily generate an extra space that requires laying (or a dummy mat) and that has no unevenness.
[0002]
[Prior art]
Conventionally, various floor heating technologies have been proposed and put into practical use. As an example of this floor heating technology, a floor heating mat in which a heat medium conduit for passing a heat medium such as hot water is embedded in a plate-like body (or base body) prepared from foamed synthetic resin or the like is laid on the floor surface. There is a technique in which a surface covering material (or a covering material) such as a carpet or a wooden decorative board is laid on the upper side to form a floor that can be heated. This kind of floor heating mat is placed in a place where it is desired to heat indoors. At this time, a dummy plate made of the same or different material as the floor heating mat is laid on the floor portion that does not require heating. In this method, a barrier-free floor without unevenness is used, and the same feeling when walking on the floor is used.
[0003]
The ends of the heat medium conduits embedded in the plate-like body (base body) constituting the floor heating mat described above are collected on the peripheral portion of the plate-like body or the header portion arranged on the outside of the plate-like body. It is connected to a heat medium control unit for controlling the supply amount and temperature of the heat medium installed at a proper place or on the wall surface side or corner of the room through a heat medium conduit. This heat transfer medium conduit is normally embedded and fixed in the dummy plate described above, and the dummy plate is finely adjusted according to the size and size of the place where the dummy plate is laid, and then the floor surface. Laid at the desired location.
[0004]
As a method for embedding and fixing the heat medium conduit in the dummy plate, as described in Japanese Patent Laid-Open No. 11-72237 (Patent Document 1), a U-shaped hard resin having a cross-sectional shape opened downward. The mold material is placed on the heat medium conduit disposed on the floor surface, and the ear piece provided at the lower edge of the mold material is screwed to the base floor surface to fix the heat medium conduit to the floor surface. There has been proposed a method in which a dummy plate is laid in a gap between the mold material placed on the heat medium conduit and the floor heating mat.
[0005]
However, in the case of the above-described method, when the dummy plate is laid in the gap between the hard resin mold and the floor heating mat, the size of the dummy plate is reduced depending on the width of the hard resin mold, the fixing position, and the like. There is a drawback that the adjustment is required and the operation becomes complicated. The inventors studied to eliminate the complexity of the fine adjustment work, and filed a patent application for the completed invention first (see Patent Document 2, Prior Application 1, Prior Application 2).
[0006]
As a result of further studies, it has been found that it is sometimes difficult to cope with the proposed auxiliary member for connecting pipe guides when the number of heating medium conduits is changed in accordance with the size of the laying place. In addition, when using the auxiliary members proposed in the prior application 1 and the prior application 2, etc., it has been found that there is a difficulty in that an extra space is generated in the laying place and a wide dummy plate must be arranged.
