The product placement surface of each shelf 7 is on the side opposite to the side facing the fire protection target area (the space of each shelf 6a) around the tube 4 that extends in a rectangular loop around the lower edge of the plate 7. There is a right-angle wall surface composed of the side edge portion 7a and the edge portion 7b. The net 5 shown in FIG. 2 is attached to the inner side of a right-angle wall surface around the tube 4 that is wound around the lower surface side edge of each shelf plate 7 in a rectangular loop shape, and the lower surface side edge portion of each shelf plate 7. The side of the tube 4 facing the fire protection area of the rectangular tube 4 is covered, and the opposite side of the side of the tube 4 facing the fire protection area of the rectangular loop is formed on the lower edge of each shelf 7. A tubular tube (piping) housing space 9 is formed in the piping path of the tube 4 in each shelf 6a by the lower surface side edge of each shelf 7 by the right-angle wall surface existing around. By inserting the tube 4 into the housing space 9, the tube 4 is wound in a rectangular loop shape on the lower surface side edge of each shelf plate 7. Therefore, the network 5 shown in FIG. 2 forms a cylindrical tube housing space 9 for inserting the tube 4 in the wall present around the tube 4, the tube wall of the tube 4 to be inserted into the tube housing space 9 It covers a part of the surrounding area. Further, the net 5 is made of a metal net or a resin net having a higher melting point than the molding material of the tube 4 and having a net having a predetermined size described later.

また、図２に示す網５は、各棚板７における商品載置面７ａの側縁部分下面と縁部７ｂの端部内面に接合させる平坦な接合部５ｂをそれぞれ板状の網押さえ１０とボルト・ナット１１で着脱自在に締め付ける方法で取り付けているが、各棚板７における商品載置面７ａの側縁部分下面と縁部７ｂの端部内面にこれら各面との間に網５の接合部５を着脱自在に嵌合する嵌合部を形成するための網取り付け金具を複数個固着しておき、嵌合方式で着脱自在に取り付けたり、各棚板７における商品載置面７ａの側縁部分下面と縁部７ｂの端部内面にチューブ４の成形材料の融点より高い温度耐熱の接着剤によって直接接着固定しても良い。さらに、網５は、各棚板７の下面側縁部の１側縁に対し１本ずつ設け、４本の網５によって各棚板７の角部を除く下面側縁部にチューブ収容空間９を形成したり、各棚板７の下面側縁部に沿うように１本の長い網５を矩形ループ状に曲げ加工し、各棚板７の下面側縁部に連続してチューブ収容空間９を形成しても良い。チューブ収容空間９に対するチューブ４の引き込み及び引き出しは、チューブ収容空間９が各棚板７の各角部で途切れる前者の場合はその途切れ部分で行うことができ、連続する後者の場合はチューブ収容空間９が各棚板７の１つの角部で途切れるように、１本の長い網５を矩形ループ状に曲げ加工することにより、その途切れ部分で行うことができる。またさらに、図２に示す網５は、平坦な両接合部５ｂ間の網主部５ａを幅方向に湾曲し、断面形状が扇形のチューブ収容空間９を形成しているが、網主部５ａを平坦に形成することで、断面形状が三角形のチューブ収容空間９を形成することができ、これ以外でもＬ字状等に折り曲げることによって、断面形状が四角形以上の多角形のチューブ収容空間９を形成することができる。本実施の形態では、網５がチューブ４の周囲に存在する直角な壁面とで当該チューブ４を挿通させる筒状のチューブ収容空間９を形成しているが、例えばチューブ４を店舗等の壁面や天井面に直接張り巡らせる場合等、チューブ４の周囲に平坦な１壁面しか存在しない場合には、幅方向に半円状に曲げたり、ＶやＬ字状、コ字状等に折り曲げた網主部５ａを有する網５によって平坦な壁面や天井面とでチューブ４を挿通させる筒状のチューブ収容空間９を形成することができる。 Further, the net 5 shown in FIG. 2 includes a plate-shaped net presser 10 and a flat joint portion 5b that is joined to the bottom surface of the side edge portion of the product placement surface 7a and the inner surface of the end portion of the edge portion 7b. The bolts and nuts 11 are attached in such a manner that they can be detachably attached. However, the net 5 is provided between the respective surfaces on the bottom surface of the side edge portion of the product placing surface 7a and the inner surface of the end portion of the edge portion 7b. A plurality of mesh fittings for forming a fitting portion for detachably fitting the joint portion 5 are fixed, and can be detachably attached by a fitting method, or the product placement surface 7a on each shelf board 7 can be attached. It may be directly bonded and fixed to the lower surface of the side edge portion and the inner surface of the end portion of the edge portion 7b with an adhesive having a heat resistance higher than the melting point of the molding material of the tube 4. Further, one mesh 5 is provided for one side edge of the lower surface side edge of each shelf plate 7, and the tube accommodating space 9 is provided on the lower surface side edge portion excluding the corners of each shelf plate 7 by the four meshes 5. Or a long net 5 is bent into a rectangular loop shape along the lower side edge of each shelf 7, and the tube receiving space 9 is continuous with the lower side edge of each shelf 7. May be formed. In the former case where the tube housing space 9 is interrupted at each corner of each shelf plate 7, the tube 4 can be pulled in and pulled out of the tube housing space 9. In the latter case, the tube housing space can be pulled out. By bending one long net 5 into a rectangular loop shape so that 9 is interrupted at one corner of each shelf plate 7, it can be performed at the interrupted portion. Furthermore, the net 5 shown in FIG. 2 has a net main part 5a between the flat joints 5b curved in the width direction to form a tube housing space 9 having a sectoral cross section. The tube storage space 9 having a triangular cross-sectional shape can be formed by forming the tube in a flat shape, and a polygonal tube storage space 9 having a quadrangular or more cross-sectional shape can be formed by bending the L-shaped tube in addition to this. Can be formed. In the present embodiment, the tubular tube housing space 9 through which the mesh 5 is inserted is formed by a right-angle wall surface around the tube 4, but the tube 4 is, for example, a wall surface of a store or the like When there is only one flat wall around the tube 4 such as when it is stretched directly on the ceiling surface, it is bent into a semicircular shape in the width direction or bent into a V, L shape, or U shape, etc. A cylindrical tube housing space 9 through which the tube 4 can be inserted with a flat wall surface or ceiling surface can be formed by the net 5 having the portion 5a.

なお、陳列棚６の支柱８に這わせるチューブ４に対しても、各棚板７の下面側縁部に矩形ループ状に這わせるチューブ４と同様に、図示しない網によってチューブ４の周囲に存在する壁面とで当該チューブ４を挿通させる筒状のチューブ収容空間を形成し、このチューブ収容空間に挿通させるチューブ４の管壁の周囲一部分を覆うことが望ましい。 It should be noted that, similarly to the tube 4 that is wound in a rectangular loop shape on the lower edge of each shelf plate 7, the tube 4 that is swung around the column 8 of the display shelf 6 exists around the tube 4 by a net (not shown). It is desirable to form a cylindrical tube housing space through which the tube 4 is inserted with the wall surface to be covered, and to cover a part of the periphery of the tube wall of the tube 4 to be inserted into the tube housing space.

以上のように構成した陳列棚用自動消火装置は、消火薬剤貯蔵容器１の内圧によってチューブ４内の管路を常時加圧した状態で待機している。この待機状態で、例えば陳列棚６の下から２段目の棚部６ａに陳列している商品から出火すると（火災発生）、図２に示すように、陳列棚６の下から２段目の棚部６ａを監視している陳列棚６の下から３段目の棚板７の下面側縁部に矩形ループ状に這わせたチューブ４の、炎１２の熱により最も高温になった部分（溶けて弱くなった部分）に孔４ａが開き、消火薬剤貯蔵容器１の内圧によって容器１に充填されている消火薬剤１３をチューブ１１に開いた孔４ａから放射させて消火を行う。このように、チューブ４は消火薬剤１３を運ぶ配管と、火炎１２を感知する感知器と、消火薬剤１３を放射するヘッド（ノズル）の３つの役目を果たしている。なお、チューブ４に孔４ａが開く温度、即ち火災感知温度は、チューブ４の成形材料や管壁の厚み等によって適宜設定でき、１０５℃〜１１５℃の範囲で設定することが望ましい。 The display shelf automatic fire extinguishing apparatus configured as described above stands by in a state where the pipe line in the tube 4 is constantly pressurized by the internal pressure of the fire extinguishing agent storage container 1. In this standby state, for example, when a fire breaks out from a product displayed on the second shelf 6a from the bottom of the display shelf 6 (fire occurs), as shown in FIG. The portion of the tube 4 that has been placed in a rectangular loop shape on the lower side edge of the third shelf 7 from the bottom of the display shelf 6 that is monitoring the shelf 6a (because of the heat of the flame 12) -out melts weakened portion) in the hole 4a is opened, firefighters by radiating extinguishing agent 13 is filled in the container 1 by the inner pressure of the fire extinguishing agent storage vessel 1 from the hole 4a was opened in the tube 11. In this way, the tube 4 serves three functions: a pipe that carries the fire extinguishing agent 13, a sensor that detects the flame 12, and a head (nozzle) that radiates the extinguishing agent 13. Incidentally, the tube 4 to a temperature holes 4a are Open, i.e. fire detection temperature can be set appropriately such as by molding or wall thickness of the tube 4, it is preferable to set within the range of 105 ° C. to 115 ° C..

また、図２に示すように、当該自動消火装置においてはチューブ４の孔４ａから放射される消火薬剤１３を、チューブ４の管壁の周囲一部分を覆っている前記網５によって、広範囲に拡散させる。これによって、チューブ４に開いた孔４ａからでは消火薬剤１３を線状にしか放射できず、放射方向が必ずしも火源に向いていなくても、網５の消火薬剤拡散機能によって消火薬剤１３を確実に火源に到達させることができ、有効で効果的な消火を行うことができる。また、消火薬剤１３として泡水溶液等の泡消火薬剤を使用した場合、前記網５を通すことにより発泡させることができ、前記網５を発泡機構としても機能させることができる。さらに、チューブ４の孔４ａから放射される消火薬剤１３の一部が網５に衝突して拡散する際に、消火薬剤１３を微細化拡散放射することもできる。 In addition, as shown in FIG. 2, in the automatic fire extinguishing apparatus, the fire extinguishing agent 13 radiated from the hole 4 a of the tube 4 is diffused over a wide range by the net 5 covering a part of the periphery of the tube wall of the tube 4. . Thus, than from the hole 4a was opened in the tube 4 can only be emitted extinguishing agent 13 linearly, even if the radiation direction not necessarily suited to fire source, ensuring fire extinguishing agent 13 by fire extinguishing agent diffusing function of the network 5 Can reach the fire source, and effective and effective fire extinguishing can be performed. Further, when a foam fire-extinguishing agent such as an aqueous foam solution is used as the fire-extinguishing agent 13, foaming can be performed by passing the mesh 5, and the mesh 5 can also function as a foaming mechanism. Furthermore, when a part of the extinguishing agent 13 radiated from the hole 4a of the tube 4 collides with the net 5 and diffuses, the extinguishing agent 13 can be finely diffused and radiated.

ここで、前記網５は、チューブ４の成形材料より高い融点を有する金網又は樹脂網からなるために、チューブ４に孔４ａが開き、消火薬剤１３が放射される時点で熱変形したり、溶けることなく確実に消火薬剤拡散機能を発揮することができる。また、前記網５は網目の大きさは、上記のような消火薬剤拡散機能を確実に得るために、チューブ４に開く孔４ａより小さく、その孔４ａから放射される消火薬剤１３が通過可能な大きさに形成することが望ましい。 Here, the network 5 is, to become a wire mesh or resin network having a higher melting point than the molding material of the tube 4,-out hole 4a opens into the tube 4, or thermally deformed at the time the fire extinguishing agent 13 is emitted, A fire extinguishing agent diffusing function can be surely exhibited without melting.
