Description

本発明は、床を利用した輻射空調に用いられる噴流ノズル及びこれを用いた輻射空調構造に関する。   The present invention relates to a jet nozzle used for radiation air conditioning using a floor and a radiation air conditioning structure using the same.

近年、床下から床面を温め（或いは冷却）、床面からの輻射熱（冷輻射）により室内の
空調を行う輻射空調構造が行われている。これは、床下に配置した空調空気を送るダクト等に設けた多数の噴流ノズルから空調空気を床面に向けて吹き出し、床面を冷暖しその輻射効果を利用するものである。
この輻射空調構造においては、良好な輻射熱効果を得るために、噴流ノズルの上端部を床下面から離れない位置に配置し、空調空気を床下面に効率よく吹き付ける必要がある。In recent years, a radiant air-conditioning structure has been performed in which the floor surface is warmed (or cooled) from under the floor, and indoor air conditioning is performed by radiant heat (cold radiation) from the floor surface. In this method, conditioned air is blown out from a large number of jet nozzles provided in a duct or the like arranged under the floor to send conditioned air toward the floor surface, and the floor surface is cooled and heated to use the radiation effect.
In this radiation air-conditioning structure, in order to obtain a good radiant heat effect, it is necessary to dispose the upper end of the jet nozzle at a position that is not separated from the floor lower surface, and to efficiently blow conditioned air onto the floor lower surface.

ここで例えば、特許文献１に記載の冷暖房システムにおける熱媒体拡散部材（噴流ノズル）は図６に示すように、噴射ノズル８０の上部の円錐状の変換部材８２が冷暖房室の区画面８９（裏面）に接触するように取付けることが提案されている。この噴射ノズル８０はノズル取付金具８４を用いて取り付けられ、このノズル取付金具８４は、補強金具８６を湾曲した矩形の金属製の平板８７の中央に取り付けた形状である。   Here, for example, as shown in FIG. 6, the heat medium diffusion member (jet nozzle) in the air conditioning system described in Patent Document 1 has a conical conversion member 82 on the upper side of the injection nozzle 80 and a section screen 89 (back surface) of the air conditioning room. It is proposed to be mounted so that it contacts. The injection nozzle 80 is mounted using a nozzle mounting bracket 84. The nozzle mounting bracket 84 has a shape in which a reinforcing metal fitting 86 is attached to the center of a curved rectangular metal flat plate 87.

上記ノズル取付金具８４は、根太や軽量鉄骨に、湾曲して凸になった側を区画面側に向けて取り付ける。そして、ノズル取付金具８４の挿通孔８５に噴流ノズル８０の風導部８１の円筒を挿通し、固定リング８３を補強金具８６に接触して止める。この後に、区画面８９を形成する仕上げ材を根太に敷設すると、ノズル取付金具８４が板バネのようにたわんで、各噴流ノズル８０の変換部材８２の上端部が仕上材の下面に押し付けて、床下面に接触するように取付けるものである。   The nozzle mounting bracket 84 is mounted on a joist or a lightweight steel frame with the curved and convex side facing the section screen side. Then, the cylinder of the air guide portion 81 of the jet nozzle 80 is inserted into the insertion hole 85 of the nozzle mounting bracket 84, and the fixing ring 83 is brought into contact with the reinforcing bracket 86 and stopped. After this, when the finishing material forming the section screen 89 is laid on the joist, the nozzle mounting bracket 84 bends like a leaf spring, the upper end portion of the conversion member 82 of each jet nozzle 80 is pressed against the lower surface of the finishing material, It is attached so as to be in contact with the lower surface of the floor.

また特許文献２に記載の輻射冷暖房システムは、表層板と裏板との間に気体の熱媒体を流通させる熱媒体流通空間が形成された冷暖房室を区画する仕切りパネルを用い、この熱媒体流通空間に熱媒体を流通させるものであり、ここでは仕切りパネルを支持脚で支え、また上面が開放された直方体状のチャンバーをばねで上方に付勢し、上記熱媒体流通空間内に熱媒体を効率よく導入するようにしている。   In addition, the radiation cooling / heating system described in Patent Document 2 uses a partition panel that partitions a cooling / heating chamber in which a heat medium circulation space is formed between the surface layer plate and the back plate so as to circulate a gaseous heat medium. The heat medium is circulated through the space. Here, the partition panel is supported by the support legs, and a rectangular parallelepiped chamber having an open upper surface is urged upward by a spring to dispose the heat medium in the heat medium distribution space. We are trying to introduce it efficiently.

さて、特許文献１に記載のノズル取付金具は、根太や軽量鉄骨に取り付ける必要があり、また撓みの程度を弾性変形の範囲内として調整する必要があるため施工に手間を要するという問題がある。
また、特許文献２に記載の輻射冷暖房システムは、表層板と裏板との間に熱媒体流通空間が形成された仕切りパネルを用いるため、熱媒体の流通機構或いは仕切りパネルの構造が複雑になり製造面、コスト面で実用性に乏しく、また施工も複雑であるという問題がある。Now, the nozzle mounting bracket described in Patent Document 1 needs to be attached to a joist or a lightweight steel frame, and it is necessary to adjust the degree of bending within the range of elastic deformation.
Moreover, since the radiation cooling and heating system described in Patent Document 2 uses a partition panel in which a heat medium circulation space is formed between the surface layer plate and the back plate, the heat medium distribution mechanism or the structure of the partition panel becomes complicated. There is a problem that the practicality is poor in terms of manufacturing and cost, and the construction is complicated.

本発明は上記問題点を解決するためになされたものであり、効率よく輻射空調が行えるとともに施工性及び経済性に優れた輻射空調用の噴流ノズル及び輻射空調構造を提供することを目的とする。   The present invention has been made to solve the above-described problems, and an object thereof is to provide a jet nozzle and a radiation air-conditioning structure for radiation air-conditioning that can efficiently perform radiation air-conditioning and have excellent workability and economy. .

以上の技術的課題を解決するため、本発明に係る輻射空調用の噴流ノズルは、図１，４等に示すように、側部に導入ダクト６４からの空調空気導入口１４が設けられ、上部に向けて断面がテーパ状に広がったノズル部材４と、上記ノズル部材４の上部に被せられ、上方に配置される床材６６に向けて空調空気を噴出する噴出孔部７が周囲に複数設けられた天板６と、ナットを高さ調整可能に取付けた支持脚８とを有し、上記支持脚のナットの上部に、上記ノズル部材を高さ調整可能に配置した構成である。   In order to solve the above technical problems, the jet nozzle for radiant air conditioning according to the present invention is provided with the conditioned air introduction port 14 from the introduction duct 64 at the side as shown in FIGS. A nozzle member 4 having a taper-shaped cross section toward the surface, and a plurality of ejection hole portions 7 that cover the upper portion of the nozzle member 4 and eject air-conditioned air toward the floor material 66 disposed above. The top plate 6 and a support leg 8 on which a nut can be adjusted in height are provided, and the nozzle member is arranged on the upper part of the nut of the support leg so that the height can be adjusted.

本発明に係る輻射空調用の噴流ノズルは、上記ナットを、板状ナット３６とした構成である。   The jet nozzle for radiant air-conditioning according to the present invention has a configuration in which the nut is a plate-like nut 36.

本発明に係る輻射空調用の噴流ノズルは、上記支持脚８の上部に、上記床材６６を支持する床支持部材１０を高さ調整可能に取り付けた構成である。   The jet nozzle for radiant air conditioning according to the present invention has a configuration in which the floor support member 10 that supports the floor material 66 is attached to the upper portion of the support leg 8 so that the height can be adjusted.

本発明に係る輻射空調用の噴流ノズルは、上記天板６の噴出孔部７の近傍に、この噴出孔部から吹き出される空調空気の向きを外向きかつ斜め上方に導くガイド片２６を設けた構成である。   The jet nozzle for radiant air-conditioning according to the present invention is provided with a guide piece 26 that guides the direction of the conditioned air blown out from the jet hole portion outward and obliquely upward in the vicinity of the jet hole portion 7 of the top plate 6. It is a configuration.

本発明に係る輻射空調用の噴流ノズルは、上記天板６の上部に、この天板と同様な位置に噴出孔部５７を設けた移動天板５６を配置し、上記天板６に対してこの移動天板５６を回転移動させることにより、両噴出孔部７，５７によって形成される開孔部５８の大きさを変化させ、この開孔部を通過する空調空気の風量を調整可能にした構成である。   The jet nozzle for radiant air conditioning according to the present invention has a movable top plate 56 provided with an ejection hole portion 57 at the same position as the top plate above the top plate 6. By rotating and moving the movable top plate 56, the size of the opening 58 formed by both the ejection holes 7 and 57 is changed, and the air volume of the conditioned air passing through the opening can be adjusted. It is a configuration.

本発明に係る輻射空調構造は、図４に示すように、床スラブ上に空調空気２４を流通させる空調ダクト６２を配置し、この空調ダクトに空調空気を導入する導入ダクト６４を連結し、この導入ダクト６４の他端部を上記何れかに記載の噴流ノズル２の上記空調空気導入口１４に連結し、上記導入ダクト６４を経由して上記噴流ノズルの噴出孔部７から噴出される空調空気２４を、上記床材６６の裏面部に向けて吹きつけることで輻射冷暖房を行う構成である。   As shown in FIG. 4, the radiant air-conditioning structure according to the present invention has an air-conditioning duct 62 for circulating the conditioned air 24 on the floor slab, and an introduction duct 64 for introducing conditioned air is connected to the air-conditioning duct. The other end portion of the introduction duct 64 is connected to the conditioned air introduction port 14 of the jet nozzle 2 described above, and the conditioned air ejected from the ejection hole portion 7 of the jet nozzle via the introduction duct 64. 24 is sprayed toward the back surface of the flooring 66 to perform radiant cooling and heating.

本発明に係る輻射空調用の噴流ノズルによれば、導入ダクトからの空調空気導入口が設けられ断面がテーパ状のノズル部材、噴出孔部が周囲に複数設けられた天板、支持脚を有し、支持脚のナットの上部にノズル部材を高さ調整可能に配置した構成を採用したから、空調ダクトの配置による影響を受けずに、希望する位置に噴流ノズルを配置してその位置の床材に空調空気を吹きつけることができるため、室内をより効率よく輻射冷暖房が行え、また噴出孔部から空調空気を床材に勢いよくかつ広い範囲に均一に吹き付けることができるため、室内を効率的に輻射冷暖房することができ、さらに噴流ノズルの高さの調整も容易に行え、また噴流ノズルの取り付けが簡単で施工性にも優れるという効果を奏する。   According to the jet nozzle for radiant air conditioning according to the present invention, the nozzle member having the conditioned air introduction port from the introduction duct and having a tapered section, the top plate provided with a plurality of ejection hole portions around the periphery, and the support leg are provided. Since the nozzle member is arranged on the upper part of the nut of the support leg so that the height can be adjusted, the jet nozzle is arranged at the desired position without being affected by the arrangement of the air conditioning duct.

本発明に係る輻射空調用の噴流ノズルによれば、支持脚の上部に、床材を支持する床支持部材を高さ調整可能に取り付けた構成としたから、ノズル部材の保持に加えて床材についても高さ調整可能に支持できることから、専用の支持脚が削減され、効率的に床材の支持及び空調が行えるという効果がある。   According to the jet nozzle for radiant air conditioning according to the present invention, the floor support member that supports the floor material is attached to the upper portion of the support leg so that the height can be adjusted. Since the height can be supported so that the height can be adjusted, the dedicated support legs are reduced, and the floor material can be efficiently supported and air-conditioned.

本発明に係る輻射空調用の噴流ノズルによれば、天板の噴出孔部の近傍に、空調空気の向きを外向きかつ斜め上方に案内するガイド片を設けた構成としたから、噴出孔部から吹き出される空調空気が斜め上方（外向き）に有効に導かれて広い範囲まで行き渡り、空調効率が高められるという効果がある。   According to the jet nozzle for radiation air conditioning according to the present invention, since the guide piece for guiding the direction of the conditioned air outward and obliquely upward is provided in the vicinity of the jet hole portion of the top plate, the jet hole portion The air-conditioning air blown out from the air is effectively guided obliquely upward (outward) and spreads over a wide range, thereby improving the air-conditioning efficiency.

本発明に係る輻射空調用の噴流ノズルによれば、天板の上部に移動天板を配置し、開孔部の大きさを変化させ、この開孔部を通過する空調空気を調整可能にしたから、空調空気の風量により噴出孔部の開孔部の大きさを変えることにより、この開孔部から吹き出される空調空気の風速風量を加減することができ、床材の裏面部の全体に有効に空調空気が行きわたるように調整することができ空調効率が高められるという効果がある。   According to the jet nozzle for radiant air conditioning according to the present invention, the movable top plate is arranged above the top plate, the size of the opening portion is changed, and the conditioned air passing through the opening portion can be adjusted. Therefore, by changing the size of the opening part of the ejection hole part according to the air volume of the conditioned air, the air speed of the conditioned air blown out from this opening part can be adjusted, and the entire back surface of the flooring can be adjusted. It can be adjusted so that the conditioned air is effectively distributed, and the air conditioning efficiency is improved.

本発明に係る輻射空調構造によれば、空調ダクトに導入ダクトを連結し、この導入ダクトの他端部を上記噴流ノズルの空調空気導入口に連結し、噴流ノズルの噴出孔部から噴出される空調空気を床材の裏面部に向けて吹きつける構成を採用したから、導入ダクトを介することで空調ダクトの配置による影響を受けずに、希望する位置に噴流ノズルを配置することができ、その上方の床材に空調空気を吹きつけることができるため、室内をより効率よく輻射冷暖房が行え、また噴出孔部から空調空気を床材に勢いよくかつ広い範囲に均一に吹き付けることができるため、室内を効率的に輻射冷暖房することができ、さらに噴流ノズルの高さの調整が板状ナットにより容易に行え、また噴流ノズルの取り付けが簡単で施工性にも優れるという効果を奏する。   According to the radiation air-conditioning structure of the present invention, the introduction duct is connected to the air-conditioning duct, the other end of the introduction duct is connected to the conditioned air introduction port of the jet nozzle, and the jet nozzle is ejected from the ejection hole. Since the configuration in which conditioned air is blown toward the back surface of the flooring material is adopted, the jet nozzle can be arranged at a desired position through the introduction duct without being affected by the arrangement of the air conditioning duct. Because the conditioned air can be blown to the upper floor material, the room can be radiantly cooled and heated more efficiently, and the air conditioned air can be blown from the blow hole portion to the floor material uniformly and over a wide area. The room can be efficiently radiantly cooled and heated, and the height of the jet nozzle can be easily adjusted by the plate nut, and the jet nozzle can be easily installed and has excellent workability.

上記円形ナット３８は、中央に螺孔４４が設けられた中空円板状の鋼材であり、またワッシャー４０は中空円板状の鋼材である。A plate-like nut 36 and a circular nut 38 are screwed onto the support bolt 32 of the support leg 8, and a washer 40 is interposed above the circular nut 38.
The plate-like nut 36 is made of a rectangular steel plate and has a shape in which a screw hole 42 is provided at the center. The plate-like nut 36 has a rectangular shape for ease of manual rotation, but any other size, shape, such as a quadrangle, a triangle, or a circle that can be operated by hand. Is available. In addition, a normal nut (such as a hexagon nut) may be used instead of the plate nut 36.
The circular nut 38 is a hollow disk-shaped steel material provided with a screw hole 44 in the center, and the washer 40 is a hollow disk-shaped steel material.

上記床支持部材１０は鋼材からなり、円筒状の支持部４６とこの支持部の上端部に設けられた円板状の受け部４８を有している。この支持部４６は、その先端部が上記受け部４８の中央部に設けられた孔部に突入した状態で溶接或いはかしめによって接合されている。
また支持部４６は、中央部から下半部分の筒内部には螺子溝４７が刻設され、この下半部分の外径に比べて上半部分の外径が太く形成されている。この床支持部材１０は、支持脚８の支持ボルト３２の上部に螺着されその高さ調整が可能である。The floor support member 10 is made of steel and has a cylindrical support portion 46 and a disc-shaped receiving portion 48 provided at the upper end portion of the support portion. The support portion 46 is joined by welding or caulking in a state where the tip end portion enters a hole provided in the central portion of the receiving portion 48.
In addition, the support portion 46 has a screw groove 47 formed in the cylinder in the lower half portion from the center portion, and the outer diameter of the upper half portion is larger than the outer diameter of the lower half portion. The floor support member 10 is screwed onto the upper portion of the support bolt 32 of the support leg 8 and its height can be adjusted.

上記床保持具１２は、合成樹脂材からなり、円板状の載置部５０の上部に十字状の仕切片５２が一体に立設形成された形状である。この床保持具１２は、床支持部材１０の受け部４８の上部に配置され、接着等により固定される。   The floor holder 12 is made of a synthetic resin material, and has a shape in which a cross-shaped partition piece 52 is integrally erected and formed on an upper portion of a disk-shaped mounting portion 50. The floor holder 12 is disposed on the upper portion of the receiving portion 48 of the floor support member 10 and is fixed by bonding or the like.

さて、上記噴流ノズル２の組立てに際しては、予めノズル部材４に天板６を固定しておく。そして、支持脚８の支持ボルト３２に板状ナット３６及び円形ナット３８を螺着し、この上部にワッシャー４０を嵌め、この上部に支持ボルト３２の上から嵌めたノズル部材４をその載置部２０を載せて配置する。   Now, when the jet nozzle 2 is assembled, the top plate 6 is fixed to the nozzle member 4 in advance. Then, a plate-like nut 36 and a circular nut 38 are screwed onto the support bolt 32 of the support leg 8, a washer 40 is fitted on the upper part, and the nozzle member 4 fitted on the support bolt 32 is fitted on the upper part. 20 is placed and placed.

さらに、天板６の中央の孔部２２から床支持部材１０の支持部４６を挿入し、この支持部４６を支持脚８の支持ボルト３２に螺合する。そして、この床支持部材１０の高さを調整する。
床支持部材１０の高さが定まれば、支持ボルト３２に螺合した板状ナット３６（及び円形ナット３８）を回して上方（ワッシャー４０とともに）に移動させ、床支持部材１０の下端部と板状ナット３６（及び円形ナット３８）との間にノズル部材４の載置部２０及び下部のワッシャー４０を挟持した状態で高さを固定する。この円形ナット３８と板状ナット３６との組み合わせにより、板状ナット３６の緩みが阻止される。Further, the support portion 46 of the floor support member 10 is inserted from the central hole portion 22 of the top plate 6, and this support portion 46 is screwed to the support bolt 32 of the support leg 8. Then, the height of the floor support member 10 is adjusted.
When the height of the floor support member 10 is determined, the plate-like nut 36 (and the circular nut 38) screwed to the support bolt 32 is rotated and moved upward (with the washer 40), so that the lower end of the floor support member 10 and The height is fixed in a state where the mounting portion 20 and the lower washer 40 of the nozzle member 4 are sandwiched between the plate-like nut 36 (and the circular nut 38). The combination of the circular nut 38 and the plate nut 36 prevents the plate nut 36 from loosening.

この噴流ノズル２は、床支持部材１０の高さ、及びこれに伴うノズル部材４の高さ位置を自在に調整することができる。この場合は、板状ナット３６（及び円形ナット３８）を緩め、支持脚８に螺着される床支持部材１０を回してその高さ位置を調整し、板状ナット３６（及び円形ナット３８）を再度締付けてノズル部材４を挟持し固定する。   The jet nozzle 2 can freely adjust the height of the floor support member 10 and the height position of the nozzle member 4 associated therewith. In this case, the plate nut 36 (and the circular nut 38) is loosened, and the floor support member 10 screwed to the support leg 8 is turned to adjust its height position, and the plate nut 36 (and the circular nut 38). Then, the nozzle member 4 is clamped and fixed.

上記噴流ノズル２は、床支持部材１０の位置に対して、この受け部４８の少し下方にノズル部材４の天板６が位置している。
なお、例えば、受け部４８に対してノズル部材４の位置を上下に加減したい場合には、床支持部材１０の下端部とノズル部材４の載置部２０との間に、別途ワッシャー等を介在させるようにすればよい。In the jet nozzle 2, the top plate 6 of the nozzle member 4 is positioned slightly below the receiving portion 48 with respect to the position of the floor support member 10.
For example, when it is desired to increase or decrease the position of the nozzle member 4 with respect to the receiving portion 48, a separate washer or the like is interposed between the lower end portion of the floor support member 10 and the placement portion 20 of the nozzle member 4. You can make it.

ここで、上記噴流ノズル２の天板６の噴出孔部に関する他の形態について説明する。
図３に示す噴流ノズル２（平面図）は、上記天板６の上に、重ねて回転移動可能な移動天板５６を配置したものである。なおここでは天板６は、これに設けた固定部２１によりノズル部材４のフランジ部に止着されている。
上記移動天板５６は円形の鋼板からなり、上記天板６と同様、中央部には孔部５４が設けられ、周囲部にはこの移動天板と同一中心の円周上に一定間隔で円弧形状（一定幅）の噴出孔部５７が複数形成されている。Here, the other form regarding the ejection hole part of the top plate 6 of the said jet nozzle 2 is demonstrated.
The jet nozzle 2 (plan view) shown in FIG. 3 has a movable top plate 56 disposed on the top plate 6 and capable of rotating and moving in a stacked manner. Here, the top plate 6 is fixed to the flange portion of the nozzle member 4 by a fixing portion 21 provided thereon.
The moving top plate 56 is made of a circular steel plate, and similarly to the top plate 6, a hole 54 is provided in the central portion, and circular arcs at regular intervals on the circumference of the same center as the moving top plate. A plurality of ejection hole portions 57 having a shape (constant width) are formed.

ここで、移動天板５６の噴出孔部５７は、上記天板６に設けた噴出孔部７と同じ位置に同じ間隔で設けられ、両噴出孔部同士が重合するように形成されている。この場合、噴出孔部７（噴出孔部５７）は、周方向に隣り合う噴出孔部７（噴出孔部５７）間の間隔を十分（噴出孔部７の周方向の長さと同程度に）に確保しておくのが効果的である。   Here, the ejection hole portion 57 of the movable top plate 56 is provided at the same position as the ejection hole portion 7 provided on the top plate 6 at the same interval, and is formed such that both the ejection hole portions are overlapped with each other. In this case, the ejection hole portion 7 (ejection hole portion 57) has a sufficient interval between the ejection hole portions 7 (ejection hole portions 57) adjacent in the circumferential direction (similar to the circumferential length of the ejection hole portion 7). It is effective to secure it.

そして、作業者の手により、天板６に対して移動天板５６を回転させることで、上記噴出孔部７に対してこの移動天板５６の噴出孔部５７の重なりの程度が変化し、両噴出孔部７，５７同士が連通する開孔部５８（図中の斜線部分）が形成される。このように、移動天板５６の回転操作により開孔部５８の大きさを調整することができる。
空調空気２４の風量に応じて、上記開孔部５８の大きさを変えることにより、この開孔部５８から吹き出される空調空気の風速及び風量を加減することができ、床材６６の裏面部６７の希望する範囲の全体に空調空気が行きわたるように調整することができる。
上記移動天板５６を調整した後は、この移動天板５６の中央部を上記床保持具１２等で押えて固定する。Then, by rotating the movable top plate 56 with respect to the top plate 6 by an operator's hand, the degree of overlap of the ejection hole portion 57 of the movable top plate 56 with respect to the ejection hole portion 7 changes, Opening portions 58 (shaded portions in the figure) where both the ejection hole portions 7 and 57 communicate with each other are formed. In this way, the size of the opening 58 can be adjusted by rotating the movable top plate 56.
By changing the size of the opening 58 according to the air volume of the conditioned air 24, the wind speed and air volume of the conditioned air blown out from the opening 58 can be adjusted. Adjustment can be made so that the conditioned air reaches the entire desired range of 67.
After adjusting the moving top plate 56, the central portion of the moving top plate 56 is pressed and fixed by the floor holder 12 or the like.

また、上記噴流ノズル２の噴出孔部７には、下記（図５など）に示すように、この噴出孔部７の端部を切り起こした形状のガイド片２６を設けることができる。このガイド片２６は、噴出孔部７を形成する際、天板６の該当箇所を断面コ字状（中心寄りの箇所を残して）に切り欠き、この切り欠いた片を曲げて斜め上方（ノズル部材４と同程度の傾斜）に向けたものである。   Moreover, as shown below (FIG. 5 etc.), the guide hole 26 of the shape which cut and raised the edge part of this ejection hole part 7 can be provided in the ejection hole part 7 of the said jet nozzle 2. As shown in FIG. When forming the ejection hole portion 7, the guide piece 26 cuts the corresponding portion of the top plate 6 into a U-shaped cross section (leaving the portion closer to the center), and bends the cut piece upwardly diagonally ( The inclination is about the same as that of the nozzle member 4.

このガイド片２６によれば、噴出孔部７から吹き出された空調空気が、斜め上方（外向き）に導かれて広い範囲まで行き渡るようになる。
上記ガイド片２６は、上記噴出孔部７の全部或いは一部に設ける。また、上記ガイド片２６は、上記断面コ字状に切り欠いた片を内側に屈曲した（ノズル部材４と同様の傾斜）形状としても良い、この場合においても、空調空気が斜め上方（外向き）に導かれる。According to this guide piece 26, the conditioned air blown from the ejection hole portion 7 is guided obliquely upward (outward) and reaches a wide range.
The guide piece 26 is provided on all or part of the ejection hole portion 7. Further, the guide piece 26 may have a shape in which a piece cut out in a U-shaped cross section is bent inward (inclination similar to that of the nozzle member 4). In this case, the conditioned air is obliquely upward (outwardly facing). ).

図４は、上記噴流ノズル２を用いた床下の輻射空調構造を示したものである。
この輻射空調構造は、床スラブに配置される空調ダクト６２、所定間隔をおいて配置される上記噴流ノズル２、床支持脚６３、噴流ノズル２に空調空気を導入する導入ダクト６４などを有している。また、上記噴流ノズル２及び床支持脚６３により床面を形成する床材６６が支持されている。FIG. 4 shows a radiant air conditioning structure under the floor using the jet nozzle 2.
This radiation air-conditioning structure has an air-conditioning duct 62 arranged on a floor slab, the jet nozzle 2 arranged at a predetermined interval, a floor support leg 63, an introduction duct 64 for introducing conditioned air into the jet nozzle 2. ing. Further, a floor material 66 forming a floor surface is supported by the jet nozzle 2 and the floor support leg 63.

上記空調ダクト６２は、冷暖房などの空調空気を送出する主ダクト及びこの主ダクトから分岐された分岐ダクトからなる。主ダクトは床部の周辺部に、また分岐ダクトは主ダクトから複数分岐して床部の全範囲にそれぞれ配置される。
これら空調ダクト６２は鋼材からなり、サイドカバー６８、上板６９、及び位置決め部材７０等を有する。このサイドカバー６８は断面コ字状で、基板部７２の両端部が直角に屈曲された上フランジ部７４及び下フランジ部７５からなる。上記上板６９は、長尺の板材である。The air-conditioning duct 62 includes a main duct that sends out conditioned air such as air conditioning, and a branch duct that is branched from the main duct. The main duct is arranged in the peripheral part of the floor part, and the branch ducts are branched from the main duct and arranged in the entire range of the floor part.
These air-conditioning ducts 62 are made of steel and include a side cover 68, an upper plate 69, a positioning member 70, and the like. The side cover 68 has a U-shaped cross section, and includes an upper flange portion 74 and a lower flange portion 75 in which both end portions of the substrate portion 72 are bent at a right angle. The upper plate 69 is a long plate material.

この空調ダクト６２は、床スラブに敷設したシート状の断熱材６０の上部に設置する。
空調ダクト６２は、所定の長さのサイドカバー６８を一定の間隔をおいて向き合わせて配置し、位置決め部材７０を両下フランジ部７５，７５の上部間に配置し、アンカー金具７６等を用いて床スラブに固定する。
そして、両サイドカバー６８，６８の上フランジ部７４，７４間に、平板状の上板６９を配置しビス等の止着具を用いてこれを上フランジ部７４に固定する。
上記導入ダクト６４は、コイルバネの周囲を不燃性の箔（アルミニウム箔など）で覆った屈曲自在なダクトである。This air conditioning duct 62 is installed on the upper part of the sheet-like heat insulating material 60 laid on the floor slab.
In the air conditioning duct 62, side covers 68 having a predetermined length are arranged facing each other at a predetermined interval, a positioning member 70 is arranged between the upper portions of both lower flange portions 75, 75, and an anchor fitting 76 or the like is used. And fix it to the floor slab.
Then, a flat upper plate 69 is disposed between the upper flange portions 74, 74 of the side covers 68, 68, and is fixed to the upper flange portion 74 using a fastening tool such as a screw.
The introduction duct 64 is a bendable duct in which the periphery of the coil spring is covered with a nonflammable foil (such as an aluminum foil).

上記床支持脚６３は、上記噴流ノズル２からノズル部材４を除いた形態であり、基本的な支持構造は同じである。このため床支持脚６３は、支持脚８の支持ボルト３２に、板状ナット３６及び円形ナット３８を螺合させ、また円形ナット３８の上部にワッシャー４０を介在させ、支持ボルト３２の上部に床支持部材１０を螺合した形状となる。
床支持脚６３の高さ調整に際しては、床支持部材１０を回してその高さ位置を調整し、高さが定まれば、ワッシャー４０を介在させた状態で円形ナット３８及び板状ナット３６を回して床支持部材１０の下端部に締付ける。The floor support leg 63 has a form in which the nozzle member 4 is removed from the jet nozzle 2, and the basic support structure is the same. For this reason, the floor support leg 63 is configured such that the plate nut 36 and the circular nut 38 are screwed onto the support bolt 32 of the support leg 8, the washer 40 is interposed above the circular nut 38, and the floor bolt is disposed above the support bolt 32. The support member 10 is screwed.
When adjusting the height of the floor support leg 63, the floor support member 10 is turned to adjust the height position, and when the height is determined, the circular nut 38 and the plate nut 36 are inserted with the washer 40 interposed therebetween. Turn and tighten to the lower end of the floor support member 10.

上記床材６６は、正方形状（又は矩形状）の板（パネル）材であり、４角部はそれぞれ切欠かれた形態である。この床材６６は鋼材からなるが、他に合成樹脂材、合成木材（木材と合成樹脂との混合材）等が用いられる。   The floor material 66 is a square (or rectangular) plate (panel) material, and the four corners are notched. The flooring 66 is made of steel, but synthetic resin material, synthetic wood (mixed material of wood and synthetic resin) or the like is also used.

ここで、噴流ノズル２を用いた床下の輻射空調構造の施工について説明する。
まず、床スラブ上に、所定間隔をおいて噴流ノズル２及び床支持脚６３を例えば交互に配置する。上記噴流ノズル２及び床支持脚６３は、それぞれ支持脚８の台座３０を止着具或いは接着剤を用いて床スラブに固定する。Here, construction of the radiation air conditioning structure under the floor using the jet nozzle 2 will be described.
First, for example, the jet nozzles 2 and the floor support legs 63 are alternately arranged on the floor slab at predetermined intervals. The jet nozzle 2 and the floor support leg 63 respectively fix the pedestal 30 of the support leg 8 to the floor slab using a fastener or an adhesive.

噴流ノズル２は空調ダクト６２の近傍に配置され、この空調ダクト６２のサイドカバー６８に取り付けた空調空気取出口に導入ダクト６４の端部を連結する。一方、この導入ダクト６４の他端部を噴流ノズル２の空調空気導入口１４に連結し、空調ダクト６２からの空調空気を導入ダクト６４を介してノズル部材４の内部に導入する。   The jet nozzle 2 is disposed in the vicinity of the air conditioning duct 62 and connects the end of the introduction duct 64 to the air conditioning air outlet attached to the side cover 68 of the air conditioning duct 62. On the other hand, the other end of the introduction duct 64 is connected to the conditioned air introduction port 14 of the jet nozzle 2, and the conditioned air from the air conditioning duct 62 is introduced into the nozzle member 4 through the introduction duct 64.

また、噴流ノズル２及び床支持脚６３の配置位置は、床材６６の角部（４角部又は２角部）の位置に合致するように設置する。そして、各噴流ノズル２及び床支持脚６３の上部に配置された床保持具１２に床材６６を載置する。
各床材６６は、その角部を噴流ノズル２又は床支持脚６３の床保持具１２の載置部５０に載せて固定する。一つの床保持具１２には、４枚（又は２，３枚）の床材６６の各角部をつき合わせた状態で支持する。また、各床材６６の角部が突合される床保持具１２の中央上部には、円形状のキャップ部材などを取り付けて床面の全体を平坦な状態にする。
そして、床材６６の上部には必要に応じてカーペット等を敷設し、床下からの輻射空調（冷暖房）構造を構築する。Further, the arrangement positions of the jet nozzle 2 and the floor support leg 63 are installed so as to coincide with the positions of the corners (four corners or two corners) of the floor material 66. Then, the floor material 66 is placed on the floor holder 12 disposed above each jet nozzle 2 and the floor support leg 63.
Each floor material 66 has its corner portion fixed on the mounting portion 50 of the floor holder 12 of the jet nozzle 2 or the floor support leg 63. One floor holder 12 supports the corners of four (or two or three) flooring materials 66 in a state of being brought together. In addition, a circular cap member or the like is attached to the center upper portion of the floor holder 12 where the corners of the floor materials 66 abut each other to make the entire floor surface flat.
Then, a carpet or the like is laid on the upper part of the flooring 66 as necessary to construct a radiation air conditioning (cooling / heating) structure from below the floor.

上記輻射空調構造では、冷暖房装置から空調空気２４として暖気（或いは冷気）が空調ダクト６２に送風され、さらに導入ダクト６４を経由して噴流ノズル２のノズル部材４に導入され、この空調空気２４は天板６の各噴出孔部７から上方の床材６６の裏面部６７に向けて噴き出される。   In the radiant air-conditioning structure, warm air (or cold air) is blown from the cooling / heating device as conditioned air 24 to the air-conditioning duct 62 and further introduced into the nozzle member 4 of the jet nozzle 2 via the introduction duct 64. It is ejected from the respective ejection hole portions 7 of the top plate 6 toward the back surface portion 67 of the upper floor material 66.

図５は、導入ダクト６４を介して導入された空調空気２４が、噴流ノズル２の噴出孔部７から上方の床材６６の裏面部６７に向けて吹き出される状態を示したものである。この場合、噴出孔部７から斜め上方に吹き出される空調空気２４は、さらにガイド片２６により床材６６の裏面部６７の広い範囲に案内される。
これにより、床材６６は空調空気によって暖められ（或いは冷やされ）、床材６６からの輻射作用（輻射熱、冷輻射等）、熱伝導などにより床材６６を敷設した室内の空調が行われる。FIG. 5 shows a state in which the conditioned air 24 introduced through the introduction duct 64 is blown out from the ejection hole portion 7 of the jet nozzle 2 toward the back surface portion 67 of the upper flooring 66. In this case, the conditioned air 24 blown obliquely upward from the ejection hole portion 7 is further guided to a wide range of the back surface portion 67 of the flooring 66 by the guide piece 26.
As a result, the flooring 66 is heated (or cooled) by the conditioned air, and air-conditioning in the room where the flooring 66 is laid is performed by radiation action (radiant heat, cold radiation, etc.) from the flooring 66 and heat conduction.

従って、上記実施の形態に係る噴流ノズルによれば、空調ダクトの配置による影響を受けずに、希望する位置に噴流ノズルを配置してその位置の床材に空調空気を吹きつけることができるため、室内をより効率よく輻射冷暖房が行え、またノズル部材のガイドなどにより噴出孔部から空調空気を床材に勢いよくかつ広い範囲に均一に吹き付けることができるため、室内を効率的に輻射冷暖房することができ、さらに噴流ノズルの高さの調整が板状ナットにより容易に行え、また噴流ノズルの取り付けが簡単で施工性にも優れるという効果がある。また、噴流ノズルは床材の支持も行えることから、床材のみの床支持脚が削減されて効率的であり経済性にも優れる。   Therefore, according to the jet nozzle according to the above-described embodiment, the jet nozzle can be arranged at a desired position without being affected by the arrangement of the air-conditioning duct, and the conditioned air can be blown onto the floor material at that position. , Radiant cooling and heating can be performed more efficiently in the room, and air-conditioning air can be blown to the flooring material from the blowout holes with a guide of the nozzle member and so on. In addition, the height of the jet nozzle can be easily adjusted with a plate-like nut, and the jet nozzle can be easily attached and has excellent workability. Further, since the jet nozzle can also support the floor material, the floor support leg of only the floor material is reduced, which is efficient and excellent in economic efficiency.

上記噴出ノズルを用いた輻射空調構造は、体育施設のような大空間から、オフィス、学校、店舗、さらには住宅など幅広い適用が可能である。   The radiation air-conditioning structure using the ejection nozzle can be widely applied from a large space such as a physical education facility to an office, a school, a store, and a house.

なお、上記噴流ノズル２は、床支持部材１０を取り付けて床材６６の支持が可能な形態であるが、この床支持部材１０の無い形態の第二の噴流ノズルも可能である。
この第二の噴流ノズルを用いる場合には、床材６６を支持する箇所には通常の床支持脚６３を用いて床材の支持を行う。
この第二の噴流ノズルは、ノズル部材４を支持脚８で高さ調整自在に支持する。この場合は、床支持部材１０に代えて円筒状ナット（例えば、上記筒状の支持部４６のみをナットとして使用）等のナット部材を用いて位置決めを行う。In addition, although the said jet nozzle 2 is a form which can attach the floor support member 10 and can support the flooring 66, the 2nd jet nozzle of a form without this floor support member 10 is also possible.
In the case of using this second jet nozzle, the floor material is supported by using a normal floor support leg 63 at a place where the floor material 66 is supported.
The second jet nozzle supports the nozzle member 4 with a support leg 8 so that the height can be adjusted. In this case, the positioning is performed using a nut member such as a cylindrical nut (for example, only the cylindrical support portion 46 is used as a nut) instead of the floor support member 10.

上記第二の噴流ノズルの組立てに際しては、支持脚８の支持ボルト３２に板状ナット３６及び円形ナット３８を螺着し、この上部にワッシャー４０を介在させる。そして、この支持ボルト３２に嵌めたワッシャー４０の上に、支持ボルト３２の上から嵌めたノズル部材４（天板６付き）の下部の載置部２０を載せる。   When the second jet nozzle is assembled, the plate nut 36 and the circular nut 38 are screwed onto the support bolt 32 of the support leg 8, and the washer 40 is interposed above the nut. And the mounting part 20 of the lower part of the nozzle member 4 (with the top plate 6) fitted from above the support bolt 32 is placed on the washer 40 fitted to the support bolt 32.

さらに、天板６の中央の孔部２２から上記円筒状ナットを挿入し、これを支持脚８の支持ボルト３２に螺合する。そして、この円筒状ナットの高さ位置（この位置によって、ノズル部材の高さ位置が定まる）を調整する。
次に、支持ボルト３２に螺合した板状ナット３６（及び円形ナット３８）を回して上方に移動（ワッシャー４０とともに）させ、円筒状ナットの下端部とワッシャー４０との間にノズル部材４の載置部２０を挟持した状態で固定する。
この第二の噴流ノズルは、上記ノズル部材４の天板６に設けた中央の孔部２２は、設置後は板材などで塞いでおいてもよい。Further, the cylindrical nut is inserted through the hole 22 at the center of the top plate 6 and screwed into the support bolt 32 of the support leg 8. Then, the height position of the cylindrical nut (the position of the nozzle member is determined by this position) is adjusted.
Next, the plate nut 36 (and the circular nut 38) screwed to the support bolt 32 is rotated and moved upward (with the washer 40), and the nozzle member 4 is placed between the lower end portion of the cylindrical nut and the washer 40. The mounting unit 20 is fixed in a sandwiched state.
In the second jet nozzle, the central hole 22 provided in the top plate 6 of the nozzle member 4 may be closed with a plate material or the like after installation.

この第二の噴流ノズルにおいても、上記噴流ノズル２と同様に、空調ダクトの配置による影響を受けずに、希望する位置に噴流ノズルを配置してその位置の床材に空調空気を吹きつけることができるため、室内をより効率よく輻射冷暖房が行え、またノズル部材のガイドなどにより噴出孔部から空調空気を床材に勢いよくかつ広い範囲に均一に吹き付けることができるため、室内を効率的に輻射冷暖房することができ、さらに噴流ノズルの高さの調整が板状ナットにより容易に行え、また噴流ノズルの取り付けが簡単で施工性にも優れるという効果がある。   Even in the second jet nozzle, similarly to the jet nozzle 2, the jet nozzle is arranged at a desired position without being affected by the arrangement of the air conditioning duct, and the conditioned air is blown to the floor material at the position. Therefore, the room can be efficiently radiantly cooled and heated, and air-conditioned air can be blown to the flooring material from the blowout holes with a guide of the nozzle member, etc. Radiant cooling and heating can be performed, and the height of the jet nozzle can be easily adjusted by a plate-like nut, and the jet nozzle can be easily attached and has excellent workability.
