Description

本願発明は、マット本体に小根太と称されるフローリング床材を支持するための支持材を挿入し、この小根太間を蛇行するようにして放熱用の温水パイプが配管された小根太入り床暖房用温水マットに関し、更に詳しくは、従来のマットの大きさは８ｍ2程度が限度であったものを１５ｍ2程度まで拡大し、更に温水パイプの径を従来の８ｍ2程度のマットに利用されていたのと同じ直径が５．０ｍｍのものをそのまま１５ｍ2程度の大きさのマットにまで利用し、然もマット全体において温度分布の均一化を図ることができる配管方式を採用した小根太入り床暖房用温水マットに関する。 The invention of the present application is a floor-containing flooring in which a support material for supporting a flooring floor material called “koneda” is inserted in the mat body, and a hot water pipe for heat dissipation is piped so as to meander between these kodazai Regarding the hot water mat for heating, more specifically, the size of the conventional mat was limited to about 8m2, but it was expanded to about 15m2, and the diameter of the hot water pipe was used for the conventional mat of about 8m2. Hot water for floor heating with small joists using a piping system that can use the same 5.0mm diameter as the mat with a size of about 15m2 and uniform the temperature distribution throughout the mat. Matt.

従来の温水マットは、マット本体内に上辺と下辺から交互に小根太を対辺に近いところまで挿入してこの対辺と小根太の先端間に温水パイプの渡り部を形成し、この渡り部を経由し、小根太を迂回するようにして温水パイプを配管した構成のものが通例である（特開２００４−２８５７７号公報）。 Conventional hot water mats insert small joists alternately into the mat body from the upper and lower sides to a position close to the opposite side to form a hot water pipe transition between the opposite side and the end of the small joist. However, a configuration in which a hot water pipe is arranged so as to bypass the small joist is usually used (Japanese Patent Laid-Open No. 2004-28577).

このような温水マットの場合、温水パイプは、温水ヘッダーがマット本体の下辺に近い略中央か端に取り付けられていて、このヘッダーから引き出された２本の温水パイプは、ペアーでマット本体の右半領域において小根太を迂回しながら蛇行したのち、続いて左半領域に移り、同じように蛇行しながらワンウェー方式でマット全体を一巡してからヘッダーに還る方式である。 In the case of such a hot water mat, the hot water pipe is attached to the center or end of the hot water header near the lower side of the mat body, and the two hot water pipes drawn from the header are paired to the right of the mat body. In this method, after meandering around the small joist in the half area, the process then moves to the left half area, and the entire mat is taken in a one-way manner while meandering in the same manner and then returned to the header.

しかし、このような温水マットの場合、ヘッダーから出た直後の温水の温度は約６０℃であるが、一巡して温水ヘッダーに還るまでの間において、約１０℃前後の水温の低下があり、マット本体において温度分布が均一化しないという欠点がある。 However, in the case of such a hot water mat, the temperature of the hot water immediately after coming out of the header is about 60 ° C., but there is a drop in the water temperature of about 10 ° C. until it returns to the hot water header in one cycle. There is a drawback that the temperature distribution in the mat body is not uniform.

また、温水パイプはマット本体内をワンウェー方式で一巡することから、配管距離がその分長くなり、例えば５ｍ2程度までのマットの場合はとにかく、例えば８ｍ2位の大きさになると圧損が大きくなるため、循環ポンプに大型のものを使用しなければならず、その分動力費が上昇し、また騒音や振動と云った環境に悪い影響が出る。このため、このワンウェー配管方式の場合にはマット本体の大きさに制約がある。 In addition, since the hot water pipe makes a round in the mat body by a one-way method, the piping distance becomes longer by that amount. For example, in the case of a mat of up to about 5 m2, for example, the pressure loss increases when the size is about 8 m2, for example. A large circulation pump must be used, which increases the power cost and adversely affects the environment such as noise and vibration. For this reason, in the case of this one-way piping system, the size of the mat body is limited.

そこで、温水パイプの配管を二手に分け、且つ小根太をマット本体の上下辺内に挿入して上下辺に沿って温水パイプの渡り部を形成し、小根太の両端に形成された渡り部をそれぞれ迂回して蛇行するようにした配管方式のマットが特開２００５−２４１０７１号公報に紹介されている。 Therefore, the piping of the hot water pipe is divided into two, and the small joists are inserted into the upper and lower sides of the mat body to form the transition portions of the hot water pipes along the upper and lower sides, and the transition portions formed at both ends of the small joists are formed. Japanese Laid-Open Patent Publication No. 2005-241071 introduces a piping-type mat that is configured to meander around each other.

また、この紹介されているマットは、その折り畳みのために平面視で中央に山折り線を形成し、更に前記山折り線に直交する谷折り線を形成してマット本体を小さく折り畳んで運搬がしやすいように工夫している。 In addition, the mat that has been introduced forms a mountain fold line in the center in plan view for folding, and further forms a valley fold line perpendicular to the mountain fold line to fold the mat body small and carry it. It is devised so that it is easy to do.

しかし、このマットの場合、小根太を迂回する部分に温水パイプが集中するため、温度分布が不均一になると共に小根太の上に敷設するフローリング床材において、釘打ち禁止区間がマットの中央部分と上下の部分の計３ヶ所になることから、フローリング床材を施工するのに手間がかかり、釘打ちトラブルの発生も生じ易いという問題がある。 However, in the case of this mat, the hot water pipes are concentrated on the part that detours the small joist, so the temperature distribution becomes non-uniform and the flooring material laid on the small joist has a nail-prohibited section at the center of the mat. Since there are a total of three locations in the upper and lower parts, there is a problem that it takes time to construct a flooring flooring and a trouble of nailing is likely to occur.

また、ここに紹介されているマットの場合、温水パイプには直径が５．０ｍｍのものが利用されており、この時のマットの大きさは圧損から８ｍ2程度が限度である。
そこで、もし１５ｍ2位のマットの大きさに従来径の温水パイプを用いる場合には、熱源機を大型のものに交換するか、温水パイプの径を少なくとも６．０ｍｍのものに換える必要がある。しかし、このようにパイプ径を大きくするとマットが厚くなってしまい、従来のマットに対して施工条件が大きく変わるという問題がある。 Further, in the case of the mat introduced here, a hot water pipe having a diameter of 5.0 mm is used, and the size of the mat at this time is limited to about 8 m @ 2 from pressure loss.
Therefore, if a hot water pipe with a conventional diameter is used for a mat size of about 15 m @ 2, it is necessary to replace the heat source machine with a large one or change the diameter of the hot water pipe to at least 6.0 mm. However, when the pipe diameter is increased in this manner, the mat becomes thick, and there is a problem that the construction conditions are greatly changed compared to the conventional mat.

また、熱源機から供給された温水を各温水パイプに分岐して供給する温水ヘッダーの場合、熱源機からの温水の供給口に近い温水パイプ側に温水の流れが片寄る傾向があるため、これも温度分布が均一化しない理由である。 In addition, in the case of a hot water header that branches and supplies hot water supplied from a heat source machine to each hot water pipe, the flow of hot water tends to drift toward the hot water pipe near the hot water supply port from the heat source machine. This is why the temperature distribution is not uniform.

本発明は斯る点に鑑みて提供されるものであって、その第一の目的は、パイプを従来と同じ直径５．０ｍｍのものを使用して１５ｍ2程度の大きさにまで対応できる小根太入り温水マットを提供することである。 The present invention is provided in view of such a point, and the first object is to use a pipe having a diameter of 5.0 mm, which is the same as that of the conventional pipe, and capable of accommodating a size of about 15 m 2. It is to provide a hot water mat.

更に第二の目的は、温水パイプの回路を６〜８回路まで増やして各温水パイプが一巡する延長距離の短縮を図り、これにより圧損を軽減し、更に各温水パイプの長さと配管領域を略均等化することにより温度分布の均一化を図って使い勝手のよい小根太入り温水マットを提供することである。 Furthermore, the second purpose is to increase the hot water pipe circuit to 6 to 8 circuits to shorten the extension distance of each hot water pipe, thereby reducing pressure loss and further reducing the length and piping area of each hot water pipe. It is to provide a hot water mat with small joists that is easy to use by equalizing the temperature distribution by equalization.

更に第三の目的は、温水パイプの回路数を６〜８回路まで増やすことにより同一の大きさのマットにおいては配管抵抗（圧損）を大幅に低減して循環ポンプの駆動電力の節約を図ることができる小根太入り温水マットを提供することである。 A third object is to increase the number of hot water pipe circuits to 6 to 8 circuits, thereby greatly reducing pipe resistance (pressure loss) and reducing the pump pump drive power for mats of the same size. It is to provide a hot water mat with small joists.

更に第四の目的は、マット上に敷設するフローリング床材の施工において、釘打ち禁止区間の数を１枚のマットにおいて従来の３ヶ所（３列）から２ヶ所に低減して施工性の向上を図り、併せて誤って釘打ち禁止区間に釘打ちを行ってしまうと云ったトラブルを回避又は軽減できる小根太入り温水マットを提供することである。 The fourth purpose is to improve the workability by reducing the number of nail-prohibited sections from 3 (3 rows) to 2 locations in a single mat in the construction of flooring materials laid on the mat. And to provide a hot water mat with small joists that can avoid or reduce the trouble of nailing in the nail-prohibited section by mistake.

更に第五の目的は、供給された温水の流れが片寄りがちな温水パイプは、他のパイプに比較して熱負荷が大きくかかるように配管のレイアウトに工夫を凝らして温度分布の均一化を図ることである。 The fifth purpose is to make the temperature distribution uniform by devising the piping layout so that the hot water pipe, where the flow of supplied hot water tends to be displaced, takes a larger heat load than other pipes. It is to plan.
