Description

【０００１】
【発明の属する技術の分野】
本発明は冷温水を用いた床輻射冷暖房システム、特に、隔置された２重床の間に配設される床間冷温水パイプの支持構造およびこの床間冷温水パイプ支持構造を採用した床吹出し空調・冷暖房装置に関する。
【０００２】
【従来の技術】
この種の床吹出し空調・冷暖房装置としては既に、図６に示すように、冷温水発生機３０からの冷水あるいは温水を、床パネル３１の下側に配設した冷温水パイプ３２に送水、循環させて床自体を冷却あるいは加熱し、その床輻射により室内３３を冷暖房する床輻射冷暖房システムと、空気調和機３５からの湿度あるいは温度等の調節空気を床パネル３１の下側の空間部３６に供給し、該空間部３６に連通する床パネル側部近傍に形成した吹出口３８から室３３内へ送風し、室上部の吸込口３９から空気調和機３５へ戻して循環させることにより室内を空調雰囲気に調節する、いわゆる床吹出し空調システムとの組み合わせによる空調・冷暖房装置が知られている（例えば特許第２６０２１９号）。この場合、冷温水パイプ３２はモルタル等の熱伝導率の高い被覆材３７に埋め込まれるようにして床パネル３１の下側に固定される。
【０００３】
また、近年の情報処理技術の進展、普及に伴ない、特にオフィスビルの室内で多数のパソコン、コピー機、電話機あるいはファクシミリ等のＯＡ機器を設置する場合、図７に示すように、床面４０上に前記ＯＡ機器の電源および配線用のコード４１を這わせ、また床面４０上に多数の支持脚４２を所定間隔で立設し、各支持脚４２上に複数個に分割したフロアパネル４５を開閉自在に設置した２重床構造も実施されている。室内の前記ＯＡ機器を配線コード４１に接続する際は該当箇所のフロアパネル４５を開いてコード４１を引き出して接続し、接続完了後はフロアパネル４５を閉鎖する。
【０００４】
【発明が解決しようとする課題】
しかしながら従来の２重床式冷暖房システムは、冷温水パイプ３２と床パネル３１間に被覆材３７が充填されるために、床パネル３１を開閉することができず、床パネル３１の下面にＯＡ機器の配線コード等を這わせることができない。また、冷温水パイプ３２は被覆材３７内に埋め込まれる形態となるため、冷温水パイプ３２と床パネル３１が間接接触となり、熱伝導性の点でも問題があった。さらに冷温水パイプ３２の破損、腐食等が起ったときのパイプの交換、修理に大がかりな工事が必要となる。
【０００５】
また、２重床の空間を利用して配線用コード４１を床面に這わせる構成についても、従来はコード４１が床面上をただ雑然と這っているのみであり、コード４１の本数が多くなった場合には、各コード４１がからみ合ってしまい、室内のＯＡ機器の位置を変えた場合には、所要のコードを選び出して再接続するという作業に時間を要し、必要以上に多くの床パネルを開かなければならない不都合があった。
【０００６】
本発明は上述した従来の不具合をなくし、冷温水による床輻射冷暖房システムと冷温風による床吹出し空調システムとを組み合せた空調・冷暖房装置において、冷温水パイプを上側の床パネル（フロアパネル）の裏面に接して簡単に支持でき、冷温水パイプの周囲の空間部に室内機器の電源、配線用コードを整然と、かつ簡単、迅速に這わせることができ、また装置設置工事の作業性もよく、工事費用の低減が図られる床間冷温水パイプの支持構造およびこの冷温水パイプ支持構造を採用した床吹出し空調・冷暖房装置を提供することにある。
【０００７】
【課題を解決するための手段】
本発明によれば、床面上に隔置されたフロアパネルの裏面に接して列状に配置される床間冷温水パイプの支持構造において、前記冷温水パイプを収容するように上部が開放された樋状部材と、前記床面上に設置され、かつ帯板を山形に折曲して成る複数個の帯状山形支持部材とを有し、前記樋状部材は前記帯状山形支持部材の頂部に支持され、前記帯状山形支持部材は、その裾部が前記樋状部材の伸長方向に隣接するように該樋状部材に沿って配列された床間冷温水パイプの支持構造が提供される。
【０００８】
また本発明によれば、床面上に隔置されたフロアパネルの裏面に接して列状に配置される床間冷温水パイプと、前記フロアパネルの一部に形成された空気吹出口と、冷暖房対象空間の上部に形成された空気吸込口と、前記床間冷温水パイプ周囲の床面と前記フロアパネルとの間のパネル下空間部に冷気あるいは暖気を送り込み、かつ前記フロアパネルの前記空気吹出口から前記冷暖房対象空間および前記空気吸込口を経て前記パネル下空間部へと循環させる冷暖気供給装置と、前記床間冷温水パイプに冷水あるいは温水を送って循環させる冷温水供給装置とを有し、前記床間冷温水パイプは上部が開放された樋状部材に収容され、前記樋状部材は帯板を山形に折曲して成る複数個の帯状山形支持部材の頂部に支持され、前記帯状山形支持部材はその裾部が前記樋状部材の伸長方向に隣接するように該樋状部材に沿って前記床面上に複数個配列された床吹出し空調・冷暖房装置が提供される。
【０００９】
【発明の実施の形態】
次に、本発明を好適な実施形態について図面を参照して説明する。図１は本発明の１実施形態に係る床間冷温水パイプ支持構造の部分的な斜視図、図２は樋状部材の拡大横断面図である。破線で示す冷温水パイプ１は所定間隔を有して列状に平行配置されるが、各パイプ１はそのほぼ全長にわたって樋状部材２に収容された状態で設置される。樋状部材２は図２に示すように上側が開放され、対向する２つの側辺部２ａと平坦な底辺部２ｂをもつ横断面が略Ｕ字状の長尺部材で構成されている。各々の樋状部材２は、平坦な頂部３ａをもつ帯状山形支持部材３に支持されている。
【００１０】
この実施形態の帯状山形支持部材３は、各樋状部材２の横巾寸法ｔより若干広い巾ｄの長い帯板を山形に折曲した形状を有し、各々の山形支持部材３の裾部３ｂが樋状部材２の伸長方向に隣接するように該樋状部材２に沿って列状に配置されるとともに、樋状部材２の横方向（該部材２の伸長方向に対して直角方向）にも整列して配置され、これによって上面視でみれば帯状山形支持部材３は縦列および横列のマトリックス状に並べて配置される。樋状部材２はその平坦な底辺部２ｂの部分で山形支持部材３の平坦な頂部３ａにリベット、ボルト（図１には図示省略）等の固着手段で固定される。
【００１１】
各々の帯状山形支持部材３の裾部３ｂ下端は、隣接するものどおしが平坦な底板５で一体に連結されている。このような山形支持部材３はフロアパネル９と床板８（図２）との間に配置され、かつ前記底板５がボルト等によって床板８の床面に固定される。前記床面上に山形支持部材３が設置された状態で樋状部材２内の冷温水パイプ１はフロアパネル９の裏面に接触している（図２）。なお、図１の実施形態では施工上の理由から縦方向（樋状部材２の長手方向）に２列、横方向に３列の合計６体の山形支持部材３がその裾部下端で矩形状の底板５により連結され、かつそれぞれ縦列各２体の山形支持部材３にまたがるように分割された長さの樋状部材２（合計３本）が山形支持部材３の頂部３ａに載置固定され、これによって１つの冷温水パイプ支持ユニット１０が構成され、多数の冷温水パイプ支持ユニット１０が広い床面に各々の樋状部材２の端部２ｃが整合するように敷き詰めて設置される。前記支持ユニット１０の縦方向両端の各山形支持部材３の裾部下端は横方向に細巾長尺の端板７で連結されている。なお、各山形支持部材３の各裾部下端と前記底板５および端板７は別体で製造して溶接等で連結してもよいが、コスト上の点からはこれらを一体にして１枚の板材からプレス打抜き・曲げ加工により製作するのがよい。
【００１２】
図３は上述した冷温水パイプ支持ユニット１０をフロアパネル９と床板８の床面８ａとの間の空間部に設置した場合の空調・冷暖房対象室１２の全体側面断面図である。前記室１２の基礎部となる床板８の上に、該床板８に対して一定の間隔を有してフロアパネル９が敷設されている。フロアパネル９の片隅、好ましくは窓側の隅部に溝状の冷暖気の吹出口１１が形成され、この吹出口１１の位置と反対側の前記室１２の上部、例えば天井あるいは上部壁面部位に冷暖気の吸込口１３が設けられている。
【００１３】
床板８の床面８ａ上に、そのほぼ全面を覆うように、多数の冷温水パイプ支持ユニット１０が敷き詰められ、前述したように山形支持部材３の頂部３ａの各樋状部材２に冷温水パイプ１が収容される。また、フロアパネル９と床板８との間の空間部に、かつ縦列および横列に並んだ山形支持部材３の間を這わせるようにして、複数本の配線用コードあるいは電源用コード（符号１５、図１）が張り渡される。この場合、各コード１５は床面８ａ上に固定した冷温水パイプ支持ユニット１０の上側から複数の山形支持部材３の間に落し込むように必要に応じて縦列、横列あるいは斜め方向に設置されるが、場合によっては図１の符号１５ａに例示するように一部分は山形支持部材３の中を潜らせることもできる。
【００１４】
冷温水パイプ１および配線用コード１５類を設置した後、複数枚に分割されたフロアパネル９が支持脚１６を介して樋状部材２の上に設置される。この場合、前述した如く、樋状部材２に収容された冷温水パイプ１が樋状部材２の上側開放部から露出してフロアパネル９の裏面に接するようになっている。好ましくは前記支持脚１６は高さ調整可能な螺子式のものが用いられる。
【００１５】
室外部の機械室に冷温水発生機１７および冷暖気発生機１８が設置され、冷水あるいは温水が冷温水発生機１７から冷温水ヘッダ１９および配管２０を介して床面８ａ上の冷温水パイプ１に導入され、かつこの間を循環される。冷暖気発生機１８からの湿度や温度の調節された冷気あるいは暖気は送風管２１を介して床板８に形成された送風孔２２あるいはフロアパネル９と床板８間の側方の下部壁面に形成された送風孔２３からフロアパネル９と床板８間の空間部６に送られ、フロアパネル９の隅部の吹出口１１から室１２内に導入され、該室１２の空気調和が行われ、室上部の吸込口１３から冷暖気発生機１８に戻され、かつこの間を循環される。
【００１６】
フロアパネル９の吹出口１１から吹き出された湿度、温度の調節空気は室１２内に満たされ、フロアパネル９上のＯＡ機器（図示省略）や人体からの発生熱や塵煙等は上部の吸込口１３から排出され、また、冷温水パイプ１からフロアパネル９に伝達された冷暖房熱は該フロアパネル９から室１２内に輻射され、室１２内は常に新鮮で快適な空調雰囲気に保たれる。また床面８ａ上に這わされるＯＡ機器（図示省略）の配線用コード１５類は、図１に示す如く、帯状山形支持部材３、特に該部材３の裾部３ｂによって大まかな位置決め、案内がなされ、本数が多くなっても従来のようにからみ合ったり、隅部の箇所に不必要に集中して引き出すのに手間がかかるということがなく、コード接続箇所に対応するフロアパネル９を開いて迅速、容易に必要なコード１５を引き出して前記ＯＡ機器に接続できる。
【００１７】
図４は本発明の他の実施形態に係る冷温水パイプ支持構造の部分的な拡大断面図、図５は図４の矢視Ｆからみた部分的な側面図である。なお、図４は図５のＡ−Ａ線に沿って裁断したものである。この実施形態では、帯状山形支持部材３の帯板の板巾は樋状部材２の横巾より広く形成されており、帯状山形支持部材３の頂部３ａはその中央位置に樋状部材２の横巾ｔとほぼ等しいか、あるいはこれより若干広い溝巾の凹溝２５が形成されている。樋状部材２はこの凹溝２５に収容されて支持される。また、凹溝２５の深さは樋状部材２の縦巾ｈとほぼ同等、あるいはこれより若干深い角溝となっており、したがって樋状部材２が前記山形支持部材３の凹溝２５に収容されたとき、樋状部材２は山形支持部材３の最頂部３ａの平坦面から突出することがなく、フロアパネル９は前記山形支持部材３の前記最頂部の平坦面に接触して該支持部材３に直接担持される。この場合も樋状部材２内の冷温水パイプ１はフロアパネル９の裏面に接するように該パイプ１と樋状部材２の寸法関係が定められる。
【００１８】
図４，図５の実施形態では樋状部材２は帯状山形支持部材３の頂部３ａの凹溝２５内に適切な公差で嵌合されて支持されるので、樋状部材２を前記山形支持部材３に固定するためのリベットやボルトは不要である。また、前記山形支持部材３の板厚を適切に選定することにより、フロアパネル９は前記山形支持部材３のみによって安定に支持され、図１〜図３の実施形態のようにフロアパネル９を床面８ａに支持するための支持脚１６は不要となり、それだけ工事の手間が省け、部品の数も少なくなり、コスト低減となる。なお、この実施形態でも図１のように帯状山形支持部材３を縦列，横列に適当な個数で配置して裾部３ｂを底板５で連結し、これを１つの単位の冷温水パイプ支持ユニット１０として構成し、対象とする室の大きさに応じて必要な個数の支持ユニット１０を準備するようにしてもよいことは勿論である。
【００１９】
【発明の効果】
以上説明したように本発明によれば、冷温水パイプを２重床の上側床パネルの裏面に接触させて支持するとともに、前記上側床パネルと基礎側の床板との間に空隙を確保し、この空隙部を通して空調制御された空気を前記床パネルの吹出口から室内に送り、室上部の吸込口から排出し、かつこの間を循環するようにしたので、冷温水パイプによる前記床パネルからの輻射および前述の空調空気による室内の冷暖房および空調が有効になされる。前記吹出口から前記室内に送り込まれる空気は２重床の間の前記冷温水パイプによっても冷暖気作用を受け、熱源を無駄なく利用できる。
【００２０】
また、床板とフロアパネル間に張り渡すＯＡ機器などのコード類は、その位置規制のための特別なガイド部材等を別途設けることなく、位置規制のための狭いガイド孔に挿通する必要はなく、床面上に設置した冷温水パイプの帯状山形支持部材の上側から該支持部材の裾部の間に這わせるようにして敷設できるため、コード設置工事がきわめて容易である。しかも縦列、横列に並んだ多数の前記支持部材の間に縦、横、斜めの任意の方向に伸長させ得るとともに、その大まかな位置が前記支持部材に規制されて延びるために、前記コードが多数本になっても、からみ合ったり隅の方へずれたりすることがなく、分割されたフロアパネルの該当箇所を開いて必要なコードを誤りなく引き出すことができるなど、多くの効果がもたらされる。

[Field of the Invention]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor radiant cooling / heating system using cold / hot water, in particular, a floor-to-floor cold / hot water pipe support structure disposed between two separated floors, and a floor blow-off air conditioner employing the floor-to-floor cold / hot water pipe support structure. -It relates to air conditioning equipment.
[0002]
[Prior art]
As this type of floor air-conditioning / cooling / heating apparatus, as shown in FIG. 6, cold water or hot water from the cold / hot water generator 30 is supplied to the cold / hot water pipe 32 disposed below the floor panel 31 and circulated. Then, the floor itself is cooled or heated, and the floor radiation cooling / heating system that heats and cools the room 33 by the floor radiation and the adjusted air such as humidity or temperature from the air conditioner 35 are supplied to the space 36 below the floor panel 31. Air is supplied to the interior of the room 33 through the air outlet 38 formed in the vicinity of the side of the floor panel communicating with the space 36, and returned to the air conditioner 35 from the air inlet 39 in the upper part of the room to be circulated. There is known an air conditioning / cooling / heating device using a combination with a so-called floor blowing air conditioning system that adjusts to the atmosphere (for example, Japanese Patent No. 260219). In this case, the cold / hot water pipe 32 is fixed to the lower side of the floor panel 31 so as to be embedded in a covering material 37 having a high thermal conductivity such as mortar.
[0003]
In addition, with the recent progress and spread of information processing technology, especially when a large number of OA devices such as personal computers, copiers, telephones, and facsimiles are installed in the office building room, as shown in FIG. A power supply and wiring cord 41 of the OA equipment is placed on the floor panel 45, and a plurality of support legs 42 are erected on the floor surface 40 at a predetermined interval, and a floor panel 45 divided into a plurality of parts on each support leg 42 is provided. A double-floor structure in which the doors can be opened and closed is also implemented. When connecting the OA equipment in the room to the wiring cord 41, the floor panel 45 at the corresponding location is opened, the cord 41 is pulled out and connected, and the floor panel 45 is closed after the connection is completed.
[0004]
[Problems to be solved by the invention]
However, in the conventional double floor type air conditioning system, since the covering material 37 is filled between the cold / hot water pipe 32 and the floor panel 31, the floor panel 31 cannot be opened and closed. The wiring cord etc. cannot be laid. Further, since the cold / hot water pipe 32 is embedded in the covering material 37, the cold / hot water pipe 32 and the floor panel 31 are in indirect contact, and there is a problem in terms of thermal conductivity. Furthermore, extensive work is required for pipe replacement and repair when the cold / hot water pipe 32 is damaged or corroded.
[0005]
Also, with respect to the configuration in which the wiring cord 41 is laid on the floor surface using a double floor space, the cord 41 is conventionally only cluttered on the floor surface, and the number of the cords 41 is large. In this case, the cords 41 become entangled, and when the position of the OA device in the room is changed, it takes time to select and reconnect the required cords, and more than necessary. There was an inconvenience of having to open the floor panel.
[0006]
The present invention eliminates the above-mentioned conventional problems, and in an air conditioning / cooling / heating apparatus combining a floor radiant cooling / heating system using cold / hot water and a floor blowing air conditioning system using cold / hot air, the cold / hot water pipe is connected to the back surface of the upper floor panel (floor panel). The power supply and wiring cords for indoor equipment can be neatly and easily arranged in the space around the cold / hot water pipe, and the equipment installation workability is also good. An object of the present invention is to provide a floor-to-floor cold / hot water pipe support structure capable of reducing costs and a floor blowing air-conditioning / cooling / heating apparatus adopting the cold / hot water pipe support structure.
[0007]
[Means for Solving the Problems]

[0009]
DETAILED DESCRIPTION OF THE INVENTION
Next, preferred embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a partial perspective view of an interfloor cold / hot water pipe support structure according to an embodiment of the present invention, and FIG. 2 is an enlarged cross-sectional view of a bowl-shaped member. The cold / hot water pipes 1 indicated by broken lines are arranged in parallel in a row with a predetermined interval, but each pipe 1 is installed in a state where it is accommodated in the bowl-like member 2 over almost the entire length thereof. As shown in FIG. 2, the flange-shaped member 2 is formed of a long member having an open upper side and a transverse section having two opposing side portions 2 a and a flat bottom portion 2 b that are substantially U-shaped. Each hook-shaped member 2 is supported by a band-shaped chevron support member 3 having a flat top 3a.

Such a mountain-shaped support member 3 is disposed between the floor panel 9 and the floor plate 8 (FIG. 2), and the bottom plate 5 is fixed to the floor surface of the floor plate 8 with bolts or the like. The cold / hot water pipe 1 in the bowl-shaped member 2 is in contact with the back surface of the floor panel 9 with the mountain-shaped support member 3 installed on the floor surface (FIG. 2). In addition, in the embodiment of FIG. 1, for the reason of construction, two rows in the vertical direction (longitudinal direction of the bowl-shaped member 2) and three rows in the horizontal direction, a total of six chevron support members 3 are rectangular at the lower end of the bottom. Are connected to each other by the bottom plate 5 and divided in length so as to straddle the two chevron-shaped support members 3 in each column (three in total) are placed and fixed on the top 3 a of the chevron-shaped support member 3. As a result, one cold / hot water pipe support unit 10 is configured, and a large number of cold / hot water pipe support units 10 are laid and installed on the wide floor so that the end portions 2c of the bowl-shaped members 2 are aligned. The bottom end of each chevron support member 3 at both ends in the longitudinal direction of the support unit 10 is connected by a narrow and long end plate 7 in the lateral direction. Note that the bottom end of each hem portion of each chevron support member 3 and the bottom plate 5 and end plate 7 may be manufactured separately and connected by welding or the like. It is good to produce by press punching and bending from the plate material.
[0012]
FIG. 3 is an overall side sectional view of the air conditioning / cooling target room 12 when the above-described cold / hot water pipe support unit 10 is installed in the space between the floor panel 9 and the floor surface 8a of the floor board 8. A floor panel 9 is laid on the floor plate 8 which is a base portion of the chamber 12 with a certain distance from the floor plate 8. A grooved cooling / warming air outlet 11 is formed at one corner of the floor panel 9, preferably at the corner on the window side, and cooling / heating is performed on the upper portion of the chamber 12 on the opposite side of the air outlet 11, for example, on the ceiling or the upper wall surface. A gas inlet 13 is provided.
[0013]
A large number of cold / hot water pipe support units 10 are laid on the floor surface 8a of the floor board 8 so as to cover almost the entire surface thereof, and as described above, the cold / hot water pipes are attached to the bowl-shaped members 2 on the top portion 3a of the mountain-shaped support member 3. 1 is accommodated. Further, a plurality of wiring cords or power cords (symbols 15 and 15) are provided so that the space between the floor panel 9 and the floor plate 8 is laid between the mountain-shaped support members 3 arranged in rows and columns. 1) is stretched over. In this case, the cords 15 are installed in columns, rows, or diagonal directions as needed so as to drop between the plurality of mountain-shaped support members 3 from the upper side of the cold / hot water pipe support unit 10 fixed on the floor surface 8a. However, in some cases, as illustrated by reference numeral 15a in FIG.
[0014]
After installing the cold / hot water pipe 1 and the wiring cords 15, the floor panel 9 divided into a plurality of sheets is installed on the bowl-shaped member 2 via the support legs 16. In this case, as described above, the cold / hot water pipe 1 accommodated in the bowl-shaped member 2 is exposed from the upper open portion of the bowl-shaped member 2 and comes into contact with the back surface of the floor panel 9. Preferably, the supporting leg 16 is a screw type whose height can be adjusted.
[0015]
The cold / hot water generator 17 and the cool / warm air generator 18 are installed in the machine room outside the room, and the cold / hot water pipe 1 on the floor surface 8a is supplied with cold water or hot water from the cold / hot water generator 17 through the cold / hot water header 19 and the pipe 20. And circulated between them. Cooled air or warm air whose humidity and temperature are controlled from the cool / warm air generator 18 is formed on the lower side wall surface between the air vent 22 formed in the floor board 8 or the floor panel 9 and the floor board 8 through the air duct 21. The air vent 23 is sent to the space 6 between the floor panel 9 and the floor plate 8 and is introduced into the chamber 12 through the outlet 11 at the corner of the floor panel 9. Is returned to the cool / warm air generator 18 and circulated there between.
[0016]
Humidity and temperature control air blown from the air outlet 11 of the floor panel 9 is filled in the chamber 12, and the OA equipment (not shown) on the floor panel 9 and the heat generated from the human body, dust and so on are the upper air inlet. The cooling / heating heat that is discharged from 13 and transmitted from the cold / hot water pipe 1 to the floor panel 9 is radiated from the floor panel 9 into the room 12, and the inside of the room 12 is always kept fresh and comfortable in an air-conditioned atmosphere. Further, as shown in FIG. 1, the wiring cords 15 of the OA equipment (not shown) wound on the floor surface 8a are roughly positioned and guided by the band-shaped chevron support member 3, particularly the skirt 3b of the member 3. Even if the number increases, the floor panel 9 corresponding to the cord connection point can be opened without entanglement as in the conventional case, and it does not take time and effort to unnecessarily concentrate at the corner part.

In this embodiment, the width of the band plate of the band-shaped chevron support member 3 is formed wider than the width of the hook-shaped member 2, and the top portion 3 a of the band-shaped chevron support member 3 is lateral to the hook-shaped member 2. A concave groove 25 having a groove width substantially equal to or slightly wider than the width t is formed. The bowl-shaped member 2 is accommodated and supported in the concave groove 25. Further, the depth of the concave groove 25 is a square groove that is substantially equal to or slightly deeper than the vertical width h of the bowl-shaped member 2, and therefore the bowl-shaped member 2 is accommodated in the concave groove 25 of the mountain-shaped support member 3. When this is done, the bowl-shaped member 2 does not protrude from the flat surface of the topmost portion 3a of the mountain-shaped support member 3, and the floor panel 9 comes into contact with the flat surface of the topmost portion of the mountain-shaped support member 3 and the support member 3 is directly supported. Also in this case, the dimensional relationship between the pipe 1 and the bowl-shaped member 2 is determined so that the cold / hot water pipe 1 in the bowl-shaped member 2 contacts the back surface of the floor panel 9 .
[0018]
In the embodiment of FIGS. 4 and 5, the hook-shaped member 2 is fitted and supported within a concave groove 25 of the top 3 a of the band-shaped chevron support member 3 with an appropriate tolerance, so that the hook-shaped member 2 is supported by the chevron support member. No rivets or bolts for fixing to 3 are required. Further, by appropriately selecting the plate thickness of the chevron support member 3, the floor panel 9 is stably supported only by the chevron support member 3, and the floor panel 9 is placed on the floor as in the embodiment of FIGS. The support legs 16 for supporting the surface 8a are not necessary, so that the labor of the construction is saved, the number of parts is reduced, and the cost is reduced. In this embodiment as well, as shown in FIG. 1, an appropriate number of belt-shaped chevron support members 3 are arranged in rows and rows, and the skirt portions 3b are connected by a bottom plate 5, which is connected to a unit of cold / hot water pipe support unit 10 as shown in FIG. Of course , the necessary number of support units 10 may be prepared according to the size of the target chamber .

【The invention's effect】
As described above, according to the present invention, while supporting the cold / hot water pipe in contact with the back surface of the upper floor panel of the double floor, a gap is secured between the upper floor panel and the floor board on the foundation side, Air that has been air-conditioned through this gap is sent from the floor panel outlet to the room, discharged from the suction port at the top of the room, and circulated between them. The indoor air conditioning and air conditioning with the conditioned air are effective. The air fed into the room from the outlet is also cooled / warmed by the cold / hot water pipe between the double beds, and the heat source can be used without waste.
[0020]
In addition, cords such as OA equipment stretched between the floor plate and the floor panel do not need to be inserted through a narrow guide hole for position regulation without separately providing a special guide member for position regulation, The cord installation work is very easy because the cold / hot water pipe installed on the floor surface can be laid from the upper side of the band-shaped chevron support member to the bottom of the support member. In addition, the cord can be extended between any number of the support members arranged in a row and a row in any direction of length, width, and slant, and its rough position is restricted by the support members so as to extend. Even if it becomes a book, it does not get entangled or deviate toward the corner, and many effects are brought about, such as opening a corresponding part of the divided floor panel and extracting a necessary code without error.
