防爆型危険物収納庫１の本体部の上方には、妻面を前側及び後側に向けた状態の切妻型の屋根板７、８が設けられている。詳しくは、図３に示すように、後壁部４の上端に、第１の屋根板７が回動支軸２３を介して軸着され、前壁部３の上端に、第２の屋根板８が回動支軸２４を介して軸着されている。それぞれの屋根板７、８の開放端縁部は、内側に向けて折り曲げられており、図１に示すように、第１の屋根板の折り曲げ部２５の上面に、第２の屋根板の折り曲げ部２６が係止されるように、それぞれの開放端縁部を重ね合わせている。 Above the main body of the explosion-proof dangerous goods storage 1, gable-type roof plates 7 and 8 are provided with the end face facing the front side and the rear side. Specifically, as shown in FIG. 3, the first roof plate 7 is pivotally attached to the upper end of the rear wall portion 4 via the rotation support shaft 23, and the second roof plate is attached to the upper end of the front wall portion 3. 8 is pivotally attached via a rotation support shaft 24. The open end edges of the roof plates 7 and 8 are bent inward, and the second roof plate is bent on the upper surface of the bent portion 25 of the first roof plate as shown in FIG. The open end edges are overlapped so that the portion 26 is locked.

このような構成によって、防爆型危険物収納庫１の内部に収容された有機溶剤の容器やガスボンベが燃焼又は爆発した際に、その燃焼圧又は爆圧によって、屋根板７、８が容易に開閉される。このため、屋根板７、８の材質としては、軽量で剛性を有し、尚且つ耐火性を有する金属製の薄い板材が適し、特に波形板が好ましい。 With such a configuration, when the organic solvent container or gas cylinder accommodated in the explosion-proof dangerous goods storage 1 is burned or exploded, the roof plates 7 and 8 are easily opened and closed by the combustion pressure or explosion pressure. Is done. For this reason, as a material of the roof plates 7 and 8, a thin metal plate material that is light and rigid and has fire resistance is suitable, and a corrugated plate is particularly preferable.

第１の屋根板７の折り曲げ部２５の下面側には、図３に示すように、透孔２７を有する取付部２８が設けられており、その透孔２７に、消火器操作手段としての吊下部材１１が吊り下げられている。
この吊下部材１１は、紐や鎖２９の上端に、前記取付部２８の透孔２７に係止させるための係止部３０を設け、下端にリング３１を設けたものである。このリング３１は、消火器１０の上側及び下側の操作レバーを挿通させるのに十分な大きさであり、リング３１の下側の上面部３１ａにおいて、下側の操作レバー２１を下から受けている。 As shown in FIG. 3, an attachment portion 28 having a through hole 27 is provided on the lower surface side of the bent portion 25 of the first roof plate 7, and the through hole 27 is suspended as a fire extinguisher operating means.

The ring 31 is large enough to allow the upper and lower operation levers of the fire extinguisher 10 to be inserted, and the lower operation lever 21 is received from below on the lower upper surface portion 31a of the ring 31. Yes.

上記構成の防爆型危険物収納庫１の作用を説明する。
図１に示すように、市販の消火器９を側壁部５に設けたられた消火器設置棚１０に配置し、固定ベルト２２で固定する。そして、消火器９の操作レバー２１を吊下部材１１のリング３１の中に挿通させる。この際、図３に示すように、吊下部材１１のリング３１の下側の上面部３１ａが、消火器１０の下側の操作レバー２１に接近し、この操作レバー２１を下から受けることができるように、鎖や紐２９の長さが予め調節されている。 The operation of the explosion-proof dangerous goods storage 1 configured as described above will be described.
As shown in FIG. 1, a commercially available fire extinguisher 9 is placed on a fire extinguisher installation shelf 10 provided on the side wall 5, and is fixed by a fixing belt 22. Then, the operation lever 21 of the fire extinguisher 9 is inserted into the ring 31 of the suspension member 11. At this time, as shown in FIG. 3, the lower upper surface portion 31a of the ring 31 of the suspension member 11 approaches the lower operation lever 21 of the fire extinguisher 10, and can receive the operation lever 21 from below. The length of the chain or string 29 is adjusted in advance so that it can be done.

防爆型危険物収納庫１の内部で軽度の爆発が起こった場合、図４に示すように、その燃焼圧又は爆圧によって、第２の屋根板８が開放される。これによって、圧力を上方向に逃がすことができ、横方向に被害が及ぶのを未然に防止できる。
また、防爆型危険物収納庫１の内部で大規模な爆発が起こった場合は、図５に示すように、その爆圧によって、第２の屋根板８と第１の屋根板７が開放される。第１の屋根板７が開放されることによって、図６に示すように、その開放端部の折り曲げ部２５に設けられた吊下部材１１が図中Ａ方向に上昇し、吊下部材１１の下端部のリング３１に挿通されている操作レバー２１が上方向に引き上げられ、消火器９のノズル９ａから消火剤が噴出する。これによって、火災の発生を未然に防止することができる。 When a slight explosion occurs inside the explosion-proof dangerous goods storage 1, the second roof plate 8 is opened by the combustion pressure or explosion pressure as shown in FIG. As a result, the pressure can be released upward, and damage in the lateral direction can be prevented.
Further, when a large-scale explosion occurs inside the explosion-proof dangerous goods storage 1, the second roof plate 8 and the first roof plate 7 are opened by the explosion pressure as shown in FIG. 5. The When the first roof plate 7 is opened, as shown in FIG. 6, the suspension member 11 provided at the bent portion 25 of the open end rises in the direction A in the figure, and the suspension member 11 The operation lever 21 inserted through the ring 31 at the lower end is pulled upward, and the fire extinguishing agent is ejected from the nozzle 9 a of the fire extinguisher 9. As a result, the occurrence of a fire can be prevented in advance.

このように、屋根板７、８を回動自在に壁部３、４に取り付けたことによって、屋根板７、８の開閉により庫内の圧力を容易に上方に逃がすことができるようになるので、屋根板７、８や壁板３、４、５、６が吹き飛んだり、破砕したりする虞がなくなる。これによって、吹き飛んだ破片による怪我を防止できる。また、破砕を防止するために屋根板７、８や壁部３、４、５、６の構造を堅牢にする必要がないので、製造コストを低減できる。また、庫内の爆発によって防爆型危険物収納庫１が破損することがないので、爆発の度に防爆型危険物収納庫１を買い換える必要がない。さらに、吊下部材１１によって、防爆型危険物収納庫の庫内に設置された消火器を操作するので、火災の発生を未然に防止することができる。 In this way, by attaching the roof plates 7 and 8 to the wall portions 3 and 4 so as to be rotatable, the pressure in the warehouse can be easily released upward by opening and closing the roof plates 7 and 8. There is no possibility that the roof plates 7, 8 and the wall plates 3, 4, 5, 6 are blown away or crushed. This prevents injuries caused by blown fragments. Moreover, since it is not necessary to make the structure of the roof boards 7 and 8 and the wall parts 3, 4, 5, and 6 robust in order to prevent crushing, manufacturing cost can be reduced. Further, since the explosion-proof dangerous goods storage 1 is not damaged by the explosion in the storage, it is not necessary to replace the explosion-proof dangerous goods storage 1 with each explosion. Furthermore, since the fire extinguisher installed in the warehouse of the explosion-proof dangerous goods storage is operated by the suspension member 11, the occurrence of a fire can be prevented in advance.

なお、吊下部材１１は、消火器１０の操作レバー２１を上側に変位できるような受け部３０ａを有する構成であればよく、必ずしも下端部にリングを設けた構造である必要はない。
また、防爆型危険物収納庫１を小型化したい場合は、壁部３、４、５、６に扉を設けず、第２の屋根板８（吊下部材１１が設けられない側の屋根板）を開閉して、物の出し入れや庫内整理をするようにすればよい。
また、爆発の初期状態において消火器を作動させたい場合は、第２の屋根板８に消火器操作手段としての吊下部材１１を取り付けてもよい。 Note that the suspension member 11 only needs to have a receiving portion 30a that can displace the operation lever 21 of the fire extinguisher 10 upward, and does not necessarily have a structure in which a ring is provided at the lower end portion.
Further, when it is desired to downsize the explosion-proof dangerous goods storage 1, the walls 3, 4, 5, 6 are not provided with doors, and the second roof plate 8 (the roof plate on the side where the hanging member 11 is not provided). ) To open and close the items and organize them.
Further, when it is desired to operate the fire extinguisher in the initial state of the explosion, a suspension member 11 as a fire extinguisher operating means may be attached to the second roof plate 8.

The fire extinguisher operating means 52 is rotatably supported by a suspension member 11 ′ suspended from the projecting portion 53 of the first roof plate 7 and a cam shaft 55 projecting laterally from the side wall 5 ′. The cam member 56 is formed.

吊下部材１１’は、下端部に縦長のリング３１’を設けた鎖２９’である。このリング３１’は、下側の受け部３１ａ’において、後述するカム部材５６の溝部５７に係止している。
カム部材５６は、正三角形状の厚板の中心に設けられた軸穴に、防爆型危険物収納庫１’の側壁部５’に設けられたカム軸５５を挿通させたものであり、１つの角部には、図８に示すように、中心部に向かって掘り下げられた溝部５７が設けられている。この溝部５７を有する角部が下側に位置するように、正三角形の底辺５９を水平方向に位置させた状態にカム部材５６を位置させることによって、この溝部５７によって吊下部材１１’が係止される係止部が構成される。カム部材５６の下側に位置する他の角部５８は、カム部材５６が回転したときに消化器９’の操作レバー２１’を押圧することとなる凸部となるものである。 The suspension member 11 'is a chain 29' provided with a vertically long ring 31 'at the lower end. The ring 31 ′ is locked to a groove portion 57 of a cam member 56 described later at the lower receiving portion 31a ′.
The cam member 56 is obtained by inserting a cam shaft 55 provided in the side wall portion 5 ′ of the explosion-proof dangerous goods storage 1 ′ into a shaft hole provided in the center of a regular triangular thick plate. As shown in FIG. 8, a groove portion 57 dug down toward the center portion is provided at one corner portion. By positioning the cam member 56 in a state where the base 59 of the equilateral triangle is positioned in the horizontal direction so that the corner portion having the groove portion 57 is located on the lower side, the suspension member 11 ′ is engaged with the groove portion 57. A locking portion to be stopped is configured. The other corner 58 located on the lower side of the cam member 56 is a convex portion that presses the operation lever 21 'of the digester 9' when the cam member 56 rotates.

カム部材５６は、常時、カム部材５６の溝部５７を消火器９’の操作レバー２１’の支点側に位置させて、底辺部５９が操作レバー２１’と平行になるようにして、操作レバー２１’に近接させた位置に配置されている。
爆発の際、第１の屋根板７’が開放され、屋根板の開放端縁部の張り出し部５３に設けられた吊下部材１１’が上昇することによって、溝部５７において吊下部材１１’のリング３１’を係止させていたカム部材５６が、図中Ｂ方向に回転する。これによって、図９に示すように、消火器９’の操作レバー２１’の作用点側に位置していた角部５８が、操作レバー２１’の上を摺動しながら押圧する。これによって、消火器９’が作動し、ダクト５１を介して消火剤が噴出される。 The cam member 56 always has the groove 57 of the cam member 56 positioned on the fulcrum side of the operation lever 21 ′ of the fire extinguisher 9 ′ so that the base 59 is parallel to the operation lever 21 ′. It is placed close to '.
During the explosion, the first roof plate 7 ′ is opened, and the suspension member 11 ′ provided on the overhanging portion 53 of the open edge of the roof plate rises, so that the suspension member 11 ′ The cam member 56 that has locked the ring 31 'rotates in the direction B in the drawing. As a result, as shown in FIG. 9, the corner 58 located on the operating point side of the operation lever 21 ′ of the fire extinguisher 9 ′ is pressed while sliding on the operation lever 21 ′. As a result, the fire extinguisher 9 ′ is activated, and the fire extinguisher is ejected through the duct 51.

上記形状のカム部材５６は、操作レバー２１’を一度押すことによって消火剤が連続噴出する構造の消火器９’に適するものであるが、操作レバー２１’の押圧を解除することによって、消火剤の噴出が停止する構造の消火器の場合は、図１０に示すように、細長い、例えば直角三角形状のカム部材５６’を用いればよい。
最も尖った角部に溝部５７’を形成し、その溝部５７’に吊下部材１１’の下端部を係止させることによって、その溝部５７’の反対側の角部５８’が、カム部材５６’が回転した際に、消火器９’の操作レバーを押圧する。 The cam member 56 having the above shape is suitable for the fire extinguisher 9 ′ having a structure in which the extinguishing agent is continuously ejected by pressing the operating lever 21 ′ once. However, the extinguishing agent is released by releasing the pressing of the operating lever 21 ′. In the case of a fire extinguisher having a structure in which the ejection of the gas is stopped, as shown in FIG.
A groove 57 ′ is formed at the sharpest corner, and the lower end of the suspension member 11 ′ is engaged with the groove 57 ′, so that the corner 58 ′ on the opposite side of the groove 57 ′ becomes the cam member 56. When 'rotates, press the operation lever of fire extinguisher 9'.

この構造のカム部材５６’を用いることによって、防爆型危険物収納庫１’の内部で爆発が起こった場合は、図１１（ａ）に示すように、その爆圧によって第１の屋根板７’が開放し、張り出し部２５’に設けられた吊下部材１１’が上昇し、吊下部材１１’が係止されている溝部５７’が上向きになるようにカム部材５６’が回転し、角部５８’で操作レバー２１’を押圧する。これによって、消火器９’が作動し、消火剤が噴出する。
さらに、第１の屋根板７’が開放されると、図１１（ｂ）に示すように、吊下部材１１’が上昇してカム部材５６’の溝部５７’から離れ、溝部５７’が上を向いた状態で停止する。これによって、カム部材５６’の底辺部５９’において、操作レバーを押し続けるので、消火剤が連続的に噴出される。 When an explosion occurs inside the explosion-proof dangerous goods storage 1 ′ by using the cam member 56 ′ having this structure, as shown in FIG. 11 (a), the first roof plate 7 is caused by the explosion pressure. The cam member 56 'rotates so that' opens, the suspension member 11 'provided on the overhanging portion 25' rises, and the groove portion 57 'to which the suspension member 11' is locked is directed upward. The operation lever 21 ′ is pressed by the corner portion 58 ′. As a result, the fire extinguisher 9 'is activated and the fire extinguishing agent is ejected.
Further, when the first roof plate 7 ′ is opened, as shown in FIG. 11 (b), the suspension member 11 ′ is lifted away from the groove portion 57 ′ of the cam member 56 ′, and the groove portion 57 ′ is raised. Stop while facing. As a result, the operation lever is kept pressed at the bottom 59 'of the cam member 56', so that the fire extinguishing agent is continuously ejected.
