Specifically, the connecting body 44 is formed of a metal such as stainless steel, and is combined with a short semi-cylindrical connecting body member whose both ends bend outward, thereby sandwiching and connecting the tank body 12. It is formed in glasses. In this embodiment, two connecting bodies 44 are respectively attached to the outer surface of the pipe portion 18 in the vicinity of the cap portion 20. Moreover, the space | interval formed in the up-down direction is provided in the both ends 44a of the connection body 44 within the height range of the tank main body 12. FIG. A first frame 48 (to be described later) is fitted into this interval and bolted to connect the connecting body 44 and the frame 14.

なお、管部１８に連結体４４を取り付ける際には、管部１８と連結体４４との間に、ウレタン等によって形成される断熱材４６が挟み込まれる。管部１８内の温度と連結体４４の温度とに差が生じた場合、管部１８と連結体４４が直接触れていると、その接触部に結露が発生する恐れがあるため、断熱材４６によってそれを防止する。 When attaching the connecting body 44 to the pipe portion 18, a heat insulating material 46 formed of urethane or the like is sandwiched between the pipe portion 18 and the connecting body 44. If there is a difference between the temperature in the pipe portion 18 and the temperature of the connecting body 44, if the pipe portion 18 and the connecting body 44 are in direct contact with each other, condensation may occur at the contact portion. Prevent it by.

フレーム１４は、ステンレス鋼などの金属によって、２つの槽本体１２を囲繞する平面矩形形状に形成される。フレーム１４は、上述の連結体４４などを介して槽本体１２を支持すると共に、貯水槽１０を建築物に取り付ける際の取付具として機能する。フレーム１４を形成する際には、溝形鋼などの汎用の形鋼を用いることができる。 The frame 14 is formed in a planar rectangular shape surrounding the two tank bodies 12 by a metal such as stainless steel. The frame 14 supports the tank body 12 via the above-described connecting body 44 and the like, and functions as an attachment for attaching the water storage tank 10 to the building. When forming the frame 14, a general-purpose shape steel such as a grooved steel can be used.

具体的には、フレーム１４は、第１フレーム４８および第２フレーム５０を含み、第１フレーム４８は、連結体４４の両端部４４ａのそれぞれに、２つの連結体４４を結ぶように接続される。つまり、第１フレーム４８は、槽本体１２の高さ範囲内で、槽本体１２の両側のそれぞれに設けられて、槽本体１２の長さ方向に延びる。第１フレーム４８は、外方に向かって開口する溝形の断面形状を有し、槽本体１２よりも長い長さを有する。たとえば、第１フレーム４８の長さは１３６０ｍｍであり、その幅は３０ｍｍであり、その高さは６０ｍｍである。 Specifically, the frame 14 includes a first frame 48 and a second frame 50, and the first frame 48 is connected to each of both end portions 44 a of the connection body 44 so as to connect the two connection bodies 44. . That is, the first frame 48 is provided on each side of the tank body 12 within the height range of the tank body 12 and extends in the length direction of the tank body 12. The first frame 48 has a groove-shaped cross-sectional shape that opens outward, and has a length longer than that of the tank body 12. For example, the first frame 48 has a length of 1360 mm, a width of 30 mm, and a height of 60 mm.

また、第１フレーム４８には、貯水槽１０を建築物に取り付ける際に利用される取付部５２が形成される。取付部５２は、たとえば、第１フレーム４８を鉛直方向に連通する略楕円形状の孔であり、この孔に後述する吊ボルト１０２等が挿通される。取付部５２は、貯水槽１０を建築物に取り付けた際の重量バランスを考慮した位置に形成され、この実施例では、連結体４４の端部近傍のそれぞれに計４つの取付部５２が形成される。 Further, the first frame 48 is formed with an attachment portion 52 that is used when the water tank 10 is attached to a building. The attachment portion 52 is, for example, a substantially elliptical hole that allows the first frame 48 to communicate in the vertical direction, and a suspension bolt 102 and the like to be described later are inserted into the hole. The attachment portion 52 is formed at a position in consideration of the weight balance when the water tank 10 is attached to the building. In this embodiment, a total of four attachment portions 52 are formed in the vicinity of the end portion of the connection body 44. The

第２フレーム５０は、槽本体１２の端面より外側で、２つの第１フレーム４８を連結し、フレーム１４の強度、延いては貯水槽１０の強度を高める。第２フレーム５０は、Ｌアングル等の金具を介して第１フレーム４８にボルト止めされて固定される。第２フレーム５０の長さ、つまり２つの第１フレーム４８の間の間隔は、たとえば４７５ｍｍである。また、槽本体１２の第２キャップ部２０ｂ側の第２フレーム４８は、上述の導入管２８および第２導出管３８と第１導出管３４との間を通るように形成され、その幅は、導入管２８および第２導出管３８と第１導出管３４との間の間隔に相当する大きさに設定される。つまり、第２キャップ部２０ｂ側の第２フレーム５０の上面に、導入管２８および第２導出管３８が乗るように沿い、その下面に、第１導出管３４が沿う。したがって、第２キャップ部２０ｂ側の第２フレーム５０に、各管２８，３４，３８を容易に固定することができ、各管２８，３４，３８に各給水管を接続した場合にも、各管２８，３４，３８の撓み等による破損を防止することができる。 The second frame 50 is connected to the two first frames 48 on the outer side of the end face of the tank body 12 to increase the strength of the frame 14 and thus the strength of the water storage tank 10. The second frame 50 is bolted and fixed to the first frame 48 via a metal fitting such as an L angle. The length of the second frame 50, that is, the distance between the two first frames 48 is, for example, 475 mm. Further, the second frame 48 on the second cap portion 20b side of the tank body 12 is formed so as to pass between the introduction pipe 28 and the second outlet pipe 38 and the first outlet pipe 34, and the width thereof is The inlet pipe 28 and the second outlet pipe 38 are set to a size corresponding to the distance between the first outlet pipe 34. That is, the introduction pipe 28 and the second outlet pipe 38 are on the upper surface of the second frame 50 on the second cap portion 20b side, and the first outlet pipe 34 is along the lower surface thereof. Therefore, each pipe | tube 28,34,38 can be easily fixed to the 2nd flame | frame 50 by the side of the 2nd cap part 20b, and when each water supply pipe | tube is connected to each pipe | tube 28,34,38, Damage due to bending of the tubes 28, 34, 38 can be prevented.

このような槽本体１２を備える貯水槽１０では、日常生活において各給水栓から水道水が使用される度に、槽本体１２内の水が自動的に入れ替わるため、常に清潔な水を確保できる。また、上述のようなキャップ構造を槽本体１２に採用することによって、槽本体１２内に空気や異物などが万一混入したとしても、それらの排出が促され、貯水槽１０のメンテナンスフリーを実現できる。しかし、台風や地震などの影響で、貯水槽が破損する場合や、貯水槽に供給される水道水の水質が悪くなる場合があるがあるため、貯水槽１０は、設備点検を容易に行えることが望ましい。そこで、貯水槽１０では、以下に詳細を示すように、ケース１６に第１点検蓋１００を設ける構造を採用した。 In the water storage tank 10 provided with such a tank main body 12, since the water in the tank main body 12 is automatically replaced every time tap water is used from each water tap in daily life, it is possible to always ensure clean water. In addition, by adopting the cap structure as described above for the tank body 12, even if air or foreign matter is mixed in the tank body 12, the discharge is promoted and the maintenance of the water storage tank 10 is realized. it can. However, because the water tank may be damaged due to typhoons or earthquakes, or the quality of tap water supplied to the water tank may deteriorate, the water tank 10 can be easily inspected. Is desirable. Therefore, the water storage tank 10 employs a structure in which the case 16 is provided with the first inspection lid 100 as will be described in detail below.

図４−図６に示すように、貯水槽１０はケース１６を備える。ケース１６は、槽本体１２、導入管２８および導出管３４，３８などを収容し、埃などから保護する。また、各接続部３０，３６，４０、バルブ３２および吸気弁４２は、たとえばケース１６内の端面１６ｄの近傍にまとめて設けられている。 As shown in FIGS. 4 to 6, the water tank 10 includes a case 16. The case 16 accommodates the tank body 12, the introduction pipe 28, the lead-out pipes 34, 38, and the like, and protects them from dust and the like. Further, each of the connection portions 30, 36, 40, the valve 32, and the intake valve 42 are provided in the vicinity of the end surface 16 d in the case 16, for example.

ケース１６は、難燃性の発泡スチロールおよびウレタン等の保温材によって形成され、槽本体１２を一定温度に保温する。ケース１６は、上面および下面が平面である扁平形状の箱形に形成される。ケース１６は、たとえば、その上部１６ａと下部１６ｂとが別体として形成され、槽本体１２などをその内部に収納した後、粘着テープを用いる等して、上部１６ａと下部１６ｂとが一体化されて箱形となる。たとえば、ケース１６の長さは１６００ｍｍであり、その幅は５３５ｍｍであり、その高さは２４０ｍｍである。 The case 16 is formed of a heat-retaining material such as flame-retardant foamed polystyrene and urethane, and keeps the tank body 12 at a constant temperature. The case 16 is formed in a flat box shape whose upper and lower surfaces are flat. For example, the upper portion 16a and the lower portion 16b of the case 16 are formed as separate bodies, and the upper portion 16a and the lower portion 16b are integrated by using an adhesive tape or the like after the tank body 12 or the like is accommodated therein. It becomes a box shape. For example, the length of the case 16 is 1600 mm, its width is 535 mm, and its height is 240 mm.

ケース１６の両側面１６ｃには、第１フレーム４８の外形に相当する大きさの窪み部５４が形成される。第１フレーム４８は、この窪み部５４に嵌り込むようにしてケース１６の両側面１６ｃから露出し、ケース１６の両端面１６ｄの近傍まで延びる。また、ケース１６の両側面１６ｃには、第１フレーム４８の各取付部５２の上方および下方を連通する切欠部５６が形成される。 On both side surfaces 16 c of the case 16, recesses 54 having a size corresponding to the outer shape of the first frame 48 are formed. The first frame 48 is exposed from the both side surfaces 16 c of the case 16 so as to fit into the recess 54, and extends to the vicinity of both end surfaces 16 d of the case 16. In addition, on both side surfaces 16 c of the case 16, cutout portions 56 are formed which communicate the upper and lower portions of the mounting portions 52 of the first frame 48.

また、ケース１６の、各接続部３０，３６，４０、バルブ３２および吸気弁４２が設けられる一方端の端面１６ｄには、複数（この実施例では６つ）の接続口５８が形成され、この接続口５８を介して各接続部３０，３６，４０に各給水管が接続される。 Further, a plurality (six in this embodiment) of connection ports 58 are formed on one end face 16d of the case 16 where the respective connection portions 30, 36, 40, the valve 32 and the intake valve 42 are provided. Each water supply pipe is connected to each connection part 30, 36, 40 via a connection port 58.

図７および図８に示すように、ケース１６には、第1点検蓋６０が開閉可能に設けられる。第１点検蓋６０は、自身の開口時に、少なくとも各接続部３０，３６，４０、バルブ３２および吸気弁４２のいずれか１つを外部から点検可能な位置に配置され、この実施例では、各接続部３０，３６，４０、バルブ３２および吸気弁４２の全てが端面１６ｄの近傍に設けられ、端面１６ｄを端とした、ケース１６の下面の中央が取り外し可能に形成されて、第１点検蓋６０となる。 As shown in FIGS. 7 and 8, the case 16 is provided with a first inspection lid 60 that can be opened and closed. The first inspection lid 60 is disposed at a position where at least one of the connection portions 30, 36, 40, the valve 32, and the intake valve 42 can be inspected from the outside when the first inspection lid 60 is opened. The connection portions 30, 36, 40, the valve 32, and the intake valve 42 are all provided in the vicinity of the end surface 16d, and the center of the lower surface of the case 16 with the end surface 16d as an end is detachably formed. 60.

第１点検蓋６０は、端部６０a、側部６０ｂおよび突起部６０ｃを含み、端面１６ｄの一部からなる端部６０aから、側部６０ｂが水平方向に突き出し、また、突起部６０ｃが貯水槽１０の幅方向の両側にそれぞれ突き出している。たとえば、端部６０aの高さは３０ｍｍであり、その幅は１５０ｍｍである。また、たとえば、側部６０ｂの長さは１１０ｍｍであり、突起部６０ｃは２０ｍｍ突き出している。 The first inspection lid 60 includes an end portion 60a, a side portion 60b, and a protruding portion 60c. The side portion 60b protrudes in the horizontal direction from the end portion 60a that is a part of the end surface 16d, and the protruding portion 60c is a water storage tank. 10 protrudes on both sides in the width direction. For example, the end 60a has a height of 30 mm and a width of 150 mm. For example, the length of the side part 60b is 110 mm, and the protrusion part 60c protrudes 20 mm.

側部６０ｂの、端部６０aと反対側の端には、第１点検蓋６０とケース１６との水平方向での接合面６０ｄが形成され、たとえば、その上部が１５ｍｍ程度突出して、接合面６０ｄは段差状に形成される。ケース１６の接合面１６ｅは、上述の接合面６０ｄに対応して、その下側が窪む段差状に形成され、接合面６０ｄと嵌まり合って当接する。また、突起部６０ｃとケース１６との接合面１６ｆも、突起部６０ｃの形状に対応して窪み、接合面１６ｆと突起部６０ｃは嵌まり合って当接する。 A joint surface 60d in the horizontal direction between the first inspection lid 60 and the case 16 is formed at the end of the side portion 60b opposite to the end portion 60a. For example, the upper portion protrudes by about 15 mm, and the joint surface 60d. Are formed in steps. The joint surface 16e of the case 16 is formed in a stepped shape corresponding to the above-described joint surface 60d, and the lower side thereof is recessed, and fits and contacts the joint surface 60d. Also, the joint surface 16f between the protrusion 60c and the case 16 is recessed corresponding to the shape of the protrusion 60c, and the joint surface 16f and the protrusion 60c are fitted and abut.

つまり、第1点検蓋６０は、接合面６０ｄと接合面１６ｅとの段差、および突起部６０ｃと接合面１６ｆとの形状を嵌め込むことで、ケース１６に固定される。 That is, the first inspection lid 60 is fixed to the case 16 by fitting the step between the joint surface 60d and the joint surface 16e and the shape of the protrusion 60c and the joint surface 16f.

図９に示すように、このような貯水槽１０を設置する場合には、先ず、少なくとも各接続部３０，３６，４０、バルブ３２および吸気弁４２のいずれか１つをケース１６の外部から点検可能な位置に、第１点検蓋６０配置する。そして、貯水槽１０の設置される空間を外部から確認可能に建築物に設けられる点検口、たとえば天井１０４に形成される点検口１０６の位置と、第１点検蓋６０の位置とが近傍になるように貯水槽の設置位置を決定する。そして、建築物の躯体、たとえば、建築物の天井裏のコンクリートスラブ１００に吊ボルト１０２を設け、貯水槽１０を吊り下げて、貯水槽１０を設置する。 As shown in FIG. 9, when installing such a water tank 10, first, at least one of each of the connection portions 30, 36, 40, the valve 32 and the intake valve 42 is inspected from the outside of the case 16. The first inspection lid 60 is disposed at a possible position. And the position of the inspection port provided in the building so that the space in which the water storage tank 10 is installed can be confirmed from the outside, for example, the inspection port 106 formed in the ceiling 104, and the position of the first inspection lid 60 are in the vicinity. Determine the location of the reservoir. And the suspension bolt 102 is provided in the concrete slab 100 of the building back of a building, for example, the ceiling back of a building, the water tank 10 is suspended, and the water tank 10 is installed.

また、このように設置された貯水槽１０の設備点検を行う場合は、先ず、点検口１０６を開けて、貯水槽１０の下面に設けられた第1点検蓋６０を端面１６ｄの方向に摺動させてケース１６から取り外す。そして、貯水槽１０を取り外さずに、ケース１６に収容したまま、たとえば各接続部３０，３６，４０の確認、バルブ３２の開閉および吸気弁４２の取替えなど、貯水槽１０の設備点検を行う。 In addition, when the facility inspection of the water storage tank 10 installed in this way is performed, first, the inspection port 106 is opened, and the first inspection lid 60 provided on the lower surface of the water storage tank 10 is slid in the direction of the end surface 16d. To remove from the case 16. Then, without removing the water storage tank 10, the equipment inspection of the water storage tank 10 is performed, for example, confirmation of each connection portion 30, 36, 40, opening / closing of the valve 32, and replacement of the intake valve 42 while being accommodated in the case 16.

具体的には、作業員が点検口１０６から貯水槽１０の点検箇所を目視して、直接設備点検を行う方法がある。この場合には、第１点検蓋６０の配置位置としては、目視可能であってかつ点検可能な位置であることが条件となる。 Specifically, there is a method in which the operator visually checks the inspection location of the water tank 10 through the inspection port 106 and directly performs the equipment inspection. In this case, the arrangement position of the first inspection lid 60 is a condition that the first inspection lid 60 can be viewed and inspected.

また、点検箇所を直接目視できない場合は、鏡、カメラ或いはロボット（点検具）などを用いて貯水槽１０の点検箇所に接近し、設備点検を行ってもよい。この場合には、点検具が点検箇所に接近できればよく、第１点検蓋６０の配置位置の条件としては、点検可能性だけでよく、目視可能性は必ずしも必要ではない。 Moreover, when the inspection location cannot be directly visually checked, the inspection location of the water storage tank 10 may be approached by using a mirror, a camera, a robot (inspection tool), or the like to perform an equipment inspection. In this case, it suffices that the inspection tool can approach the inspection location, and the condition of the arrangement position of the first inspection lid 60 is only the inspection possibility, and the visual possibility is not necessarily required.

このように、貯水槽１０は、ケース１６に第1点検蓋６０を設けたため、建築物に設置している貯水槽１０を取り外さず、ケース１６内部に収納したままで、容易に設備点検をすることができる。 Thus, since the water tank 10 provided the 1st inspection cover 60 in the case 16, it does not remove the water tank 10 installed in the building, but easily inspects the equipment while being housed inside the case 16. be able to.

また、各接続部３０，３６，４０、バルブ３２および吸気弁４２の全ては、第１点検蓋６０開口時に、外部から点検可能な位置、この実施例ではケース１６内の端面１６ｄ近傍にまとめて設けられ、その端面１６ｄに第１点検蓋６０を設けるため、各接続部３０，３６，４０、バルブ３２および吸気弁４２の全ての設備点検をまとめて行うことができる。 Further, all of the connecting portions 30, 36, 40, the valve 32, and the intake valve 42 are gathered at a position where the first inspection lid 60 can be inspected from the outside when the first inspection lid 60 is opened, in this embodiment, in the vicinity of the end face 16d in the case 16. Since the first inspection lid 60 is provided on the end surface 16d, all the facility inspections of the connection portions 30, 36, 40, the valve 32, and the intake valve 42 can be performed collectively.

さらに、第1点検蓋６０は、ケース１６の接着面以外の方向から取外し可能な構造であるため、ケース１６を設置した際に、たとえばケース１６が、コンクリートスラブ１００などの建築物の躯体に密着しても、その躯体から貯水槽１０を取り外さずに、そのまま設備点検することができる。 Furthermore, since the first inspection lid 60 has a structure that can be removed from a direction other than the bonding surface of the case 16, when the case 16 is installed, for example, the case 16 comes into close contact with a building frame such as the concrete slab 100. Even so, the equipment can be inspected as it is without removing the water tank 10 from the housing.

図１０および図１１に示すこの発明の他の実施例である貯水槽１０は、ケース１６の端面１６ｄ側の下部が取り外し可能に形成されて、第２点検蓋６２となる。以下、図１に示す貯水槽１０と同様である部分に関しては、詳細な説明は省略する。 A water storage tank 10 according to another embodiment of the present invention shown in FIGS. 10 and 11 has a lower part on the side of the end face 16d of the case 16 that is detachable to form a second inspection lid 62. Hereinafter, detailed description of the same parts as the water tank 10 shown in FIG. 1 will be omitted.

第２点検蓋６２は、端部６２ａおよび側部６２ｂを含み、端面１６ｄの下半分によって形成される端部６２ａから、ケース１６の両側面１６ｃおよびケース１６の下面によって略コ字型に形成される側部６２ｂが水平方向に突き出す。たとえば、端部６２ａの幅は５３５ｍｍであり、その高さは１２０ｍｍである。また、側部６２ｂの上部は、ケース１６に形成される窪み部５４を一部含むため、方形状に欠ける。たとえば、側部６２ｂの長さは２６０ｍｍである。側部６２ｂには、第２点検蓋６２とケース１６との水平方向での接合面６２ｃが形成される。接合面６２ｃは、たとえば、その内側が水平方向に１５ｍｍ程度突出して、段差状に形成される。ケース１６の接合面１６ｇは、上述の接合面６２ｃの段差に対応して、その内側が窪む段差状に形成され、接合面６２ｃと嵌まり合って当接する。また、第２点検蓋６２の上端には、第２点検蓋６２とケース１６との鉛直方向の接合面６２ｄが形成される。接合面６２ｄは、たとえば、その内側が鉛直方向に１５ｍｍ程度突出して、段差状に形成される。ケース１６の接合面１６ｈは、上述の接合面６２ｄの段差に対応して、その内側が窪む段差状に形成され、接合面６２ｄと嵌まり合って当接する。つまり、第２点検蓋６２は、接合面６２ｃと接合面１６ｇとの段差、および接合面６２ｄと接合面１６ｈとの段差を嵌め込むことで、ケース１６に固定される。 The second inspection lid 62 includes an end portion 62a and a side portion 62b, and is formed in a substantially U-shape from the end portion 62a formed by the lower half of the end surface 16d by the both side surfaces 16c of the case 16 and the lower surface of the case 16. The side portion 62b protrudes in the horizontal direction. For example, the width of the end 62a is 535 mm, and the height is 120 mm. Moreover, since the upper part of the side part 62b contains a part of hollow part 54 formed in the case 16, it lacks a square shape. For example, the length of the side part 62b is 260 mm. A horizontal joining surface 62c between the second inspection lid 62 and the case 16 is formed on the side portion 62b. For example, the inner surface of the joint surface 62c protrudes about 15 mm in the horizontal direction and is formed in a stepped shape. The joint surface 16g of the case 16 is formed in a stepped shape corresponding to the above-described step of the joint surface 62c, and the inner surface of the case 16 is in contact with the joint surface 62c. In addition, a vertical joint surface 62 d between the second inspection lid 62 and the case 16 is formed at the upper end of the second inspection lid 62. The joining surface 62d is formed in a stepped shape, for example, with its inner side protruding about 15 mm in the vertical direction. The joining surface 16h of the case 16 is formed in a stepped shape corresponding to the above-described step of the joining surface 62d, and is fitted into and abuts on the joining surface 62d. That is, the second inspection lid 62 is fixed to the case 16 by fitting a step between the joint surface 62c and the joint surface 16g and a step between the joint surface 62d and the joint surface 16h.

なお、第２点検蓋６２に、第1点検蓋６０を併合させて設けることも可能であり、その場合は、設備点検をする範囲に応じて、第1点検蓋６０および第２点検蓋６２のどちらを利用するかを選択する。 The first inspection lid 60 can be provided in combination with the second inspection lid 62. In this case, the first inspection lid 60 and the second inspection lid 62 can be provided according to the range of equipment inspection. Select which one to use.

このように、貯水槽１０では、ケース１６に、第1点検蓋６０と比べて大きな、第２点検蓋６２を設けたことで、設備点検が可能な範囲が広がり、より精度の高い設備点検をすることができる。 In this way, in the water storage tank 10, the case 16 is provided with the second inspection lid 62, which is larger than the first inspection lid 60, so that the range in which the equipment inspection can be performed is widened, and more accurate equipment inspection is performed. can do.

図１２および図１３に示すこの発明の他の実施例である貯水槽１０は、ケース１６の端面１６ｄ側が取り外し可能に形成されて、第３点検蓋６４となる。つまり、第３点検蓋６４は、前述の第２点検蓋６２を上部１６ａ側にも形成して、その２つを併合したような形状である。以下、図１に示す貯水槽１０と同様である部分に関しては、詳細な説明は省略する。 12 and 13, the water tank 10 according to another embodiment of the present invention is formed so that the end surface 16 d side of the case 16 can be removed, and serves as a third inspection lid 64. That is, the third inspection lid 64 has a shape in which the above-described second inspection lid 62 is also formed on the upper portion 16a side and the two are merged. Hereinafter, detailed description of the same parts as the water tank 10 shown in FIG. 1 will be omitted.

第３点検蓋６４は、端部６４ａおよび側部６４ｂを含み、端面１６ｄによって形成される端部６４ａから、ケースの上面、下面および両側面１６ｃによって方形筒状に形成される側部６４ｂが水平方向に突き出す。たとえば、端部６４ａの幅は５３５ｍｍであり、その高さは２４０ｍｍである。また、側部６４ｂの両側面１６ｃ側の中央は、ケース１６に形成される窪み部５４を一部含むため、方形状に欠ける。たとえば、側部６４ｂの長さは２６０ｍｍである。 The third inspection lid 64 includes an end portion 64a and a side portion 64b. From the end portion 64a formed by the end surface 16d, the side portion 64b formed in a rectangular tube shape by the upper surface, the lower surface, and both side surfaces 16c of the case is horizontal. Stick out in the direction. For example, the end 64a has a width of 535 mm and a height of 240 mm. Further, the center of the side portion 64b on the both side surfaces 16c side includes a part of the recessed portion 54 formed in the case 16, and thus lacks a square shape. For example, the length of the side part 64b is 260 mm.

側部６４ｂには、第３点検蓋６４とケース１６との水平方向での接合面６４ｃが形成される。接合面６４ｃは、たとえば、その内側が水平方向に１５ｍｍ程度突出して、段差状に形成される。ケース１６の接合面１６iは、上述の接合面６４ｃの段差に対応して、その内側が窪む段差状に形成され、接合面６４ｃと嵌まり合って当接する。つまり、第３点検蓋６４は、接合面６４ｃと接合面１６iとの段差を嵌め込むことで、ケース１６に固定される。 A horizontal joint surface 64c between the third inspection lid 64 and the case 16 is formed on the side portion 64b.
