一般的な貯槽構造は鉄などの金属製の材料を用いた屋根材を有し、周囲をコンクリート貯槽壁で覆われた構造となっている。特許文献1(特開2005−170471号公報)、特許文献2(特開2009−154940号公報)には、貯槽壁の上面に溜まる雨水の排水に関する構造が開示されている。   A common storage tank structure has a roof material using a metal material such as iron and is surrounded by a concrete storage tank wall. Patent Literature 1 (Japanese Patent Laid-Open Publication No. 2005-170471) and Patent Literature 2 (Japanese Patent Laid-Open Publication No. 2009-154940) disclose a structure relating to drainage of rainwater accumulated on the upper surface of a storage tank wall.

特許文献3(特開平11−20894)には、貯槽壁上の雪の塊の落下防止に関する構造が開示されている。   Patent Document 3 (Japanese Patent Application Laid-Open No. 11-20894) discloses a structure relating to prevention of falling of a snow lump on a storage tank wall.

特開2005−170471号公報JP, 2005-170471, A 特開2009−154940号公報JP, 2009-154940, A 特開平11−20894号公報JP 11-20894 A

上記従来技術もしくは技術的思想では、貯槽壁の上面における雪や雨水をいかに効率よく地上に排出するかの対応についての構造に言及しており、貯槽壁壁面の汚損防止についての記載は見当たらない。貯槽が最終的に施工完了するまでの過程で施工途上にある屋根材である金属板が錆び、この錆びによって壁面が汚されると、これを取り除くためには、水を高圧で噴射する高圧洗浄設備(ジェットウォッシャー)による噴射水によって剥離させる。これがうまくいかない(つまり、噴射水では剥離できない)場合には、たとえばグラインダーを用いて削り落とす必要があり、特に大型のLNG貯槽のように外壁面の面積が膨大な場合には、この汚れを除去するために多大な手間を要し、施工上の大きな課題となっていた。また、足場を設置し高所危険作業を行うことを余儀なくされていた。   The above-mentioned prior art or technical idea refers to the structure of how to efficiently discharge the snow and rain water on the upper surface of the storage tank to the ground, and no description about the prevention of the contamination of the storage wall is found. The metal plate which is a roofing material under construction is rusted in the process until the storage tank is finally completed construction, and if the wall is polluted by this rust, high pressure washing equipment which sprays water under high pressure to remove it Peel by jet water from (jet washer). If this does not work (that is, it can not be peeled off with the injection water), for example, it is necessary to scrape off using a grinder, and remove this dirt particularly when the area of the outer wall surface is large like a large LNG storage tank. To take a lot of time and labor, making it a major issue in construction. In addition, he was forced to set up a foothold and carry out dangerous work at heights.

本発明はこうした従来技術での問題点を解決することを企図したものであり、貯槽体の構築における作業の安全性と作業効率を格段に向上させつつ、経済効率も格段に向上させることの可能な貯槽構造及び貯槽壁壁面汚損防止構造を提供することを課題とする。   The present invention is intended to solve such problems in the prior art, and it is possible to dramatically improve the economic efficiency while dramatically improving the safety and efficiency of the work in constructing the storage tank body. It is an object of the present invention to provide an efficient storage tank structure and a storage wall surface wall contamination prevention structure.

かかる課題を解決するため、本発明の請求項1に係る発明は、鉄筋コンクリートからなる貯槽壁と、前記貯槽壁の内側天端上に受け具を介して接続される金属製屋根材と、前記貯槽壁の天端上に立設される貯槽壁壁面汚損防止構造体であって前記金属製屋根材が前記受け具に接続される高さよりも高い位置にその天端を持つ貯槽壁壁面汚損防止構造と、前記貯槽壁壁面汚損防止構造体を前記金属製屋根材から前記貯槽壁の外壁側に貫通するように該貯槽壁壁面汚損防止構造体の下方に設けられる排水パイプと、を具備して構成される。   In order to solve such problems, the invention according to claim 1 of the present invention is a storage tank wall made of reinforced concrete, a metal roofing material connected via a receptacle on an inner top end of the storage tank wall, and the storage tank A storage wall wall contamination prevention structure erected on the top end of a wall, the storage wall contamination prevention structure having the top end at a position higher than the height at which the metal roofing material is connected to the receptacle. And a drainage pipe provided below the storage wall wall surface contamination prevention structure so as to penetrate the storage wall surface wall contamination prevention structure from the metal roofing material to the outer wall side of the storage tank wall. Be done.

この発明によれば、金属製屋根材から流れ落ちてくる金属の錆や汚れを含んだ雨水は、貯槽壁上に設けられた貯槽壁壁面汚損防止構造体によって堰止められ、さらに貯槽壁壁面汚損防止構造体の下方に設けられる排水パイプによって雨水は排水される。このため、汚れた雨水が貯槽壁の壁面を伝わることがないため、錆や汚れを含んだ雨水による壁面汚損は防止することができる。   According to this invention, the rainwater containing rust and dirt of the metal that flows down from the metal roofing material is blocked by the storage wall surface contamination prevention structure provided on the storage tank wall, and further the storage wall surface contamination prevention Rainwater is drained by a drainage pipe provided below the structure. For this reason, since dirty rain water does not travel along the wall surface of the storage tank wall, it is possible to prevent wall contamination by rain water containing rust and dirt.

上記構成において「受け具」とは屋根材を受けて貯槽壁に接続させるための構造体であり、例えばトップアングルを用いることができるが、T型、くの字型などを用いてもよい。また、貯槽壁壁面汚損防止構造は屋根材から雨水を堰き止められれば、貯槽壁上面のいずれの箇所に設けられてもよい。   In the above configuration, the “receiving tool” is a structure for receiving the roofing material and connecting it to the storage tank wall. For example, a top angle can be used, but a T-shape, a V-shape, or the like may be used. In addition, the storage wall surface wall contamination prevention structure may be provided at any location on the upper surface of the storage tank wall as long as rainwater can be blocked from the roof material.

また、上記構成を備える貯槽壁壁面防止構造体は、前記貯槽壁の断面外側よりに貯槽壁の壁厚よりも薄い厚を持つコンクリート構造体であるとすることもできる。   Moreover, the storage wall surface wall prevention structure provided with the said structure can also be made into a concrete structure which has a thickness thinner than the wall thickness of a storage wall by the cross-sectional outer side of the said storage wall.

この場合の貯槽壁壁面汚損防止構造は、貯槽壁の上部のいずれかの位置に雨水を堰止めるためのコンクリートからなる貯槽壁壁面汚損防止構造体を設ける。これにより、構造体の内部に設けられた排水パイプから雨水を排出することができ、貯槽壁の汚れ防止が可能となる。貯槽壁壁面防止構造体は貯槽壁と面が一面化となるように打放し型枠を用いて仕上げることが望ましい。   In this case, the storage wall wall surface contamination prevention structure is provided with a storage tank wall surface contamination prevention structure made of concrete for retaining rainwater at any position on the upper portion of the storage tank wall. Thereby, rain water can be discharged from the drainage pipe provided in the inside of a structure, and the dirt prevention of a storage tank wall becomes possible. It is desirable to finish the storage wall surface wall prevention structure using a release form so that the storage wall and the surface become flush.

また、上記構成を備える貯槽壁壁面汚損防止構造体は、前記受け具上に設けられた堰板であるとすることもできる。この場合、堰板は鋼製を用いることとする。   Moreover, the storage wall wall surface contamination prevention structure provided with the said structure can also be taken as the weir plate provided on the said receiver. In this case, steel plate will be used as the weir plate.

この発明によれば、汚れ、錆を含んだ雨水が貯槽壁の上面を伝わらずに排水可能となる。   According to this invention, rainwater containing dirt and rust can be drained without being transmitted over the upper surface of the storage tank wall.

これまでは、貯槽壁上面の汚れは貯槽完成前にジェットウォッシャーなどを用いることによって清掃を行っていた。貯槽壁の上側面での作業は高所作業となり落下事故を起こす危険性があり、足場の設置や墜落防止措置が必須となる。本発明によれば、貯槽壁の上面の汚れを防止することにより清掃の必要がなくなることにより、安全性の向上にもつながる。   Heretofore, the dirt on the upper surface of the storage tank has been cleaned by using a jet washer or the like before completion of the storage tank. The work on the upper side of the storage wall is a high place work and there is a risk of causing a drop accident, and the installation of scaffolding and fall prevention measures are essential. According to the present invention, the prevention of the contamination of the upper surface of the reservoir wall eliminates the need for cleaning, which also leads to an improvement in safety.

さらに、上記構成を備える貯槽壁壁面汚損防止構造体は前記貯槽壁の天端仕上面となる最終ロットコンクリート中に埋め込まれもしくは該最終ロットコンクリートの一部となるようにすることもできる。   Furthermore, the storage wall wall surface contamination preventing structure having the above-described configuration may be embedded in or be a part of the final lot concrete to be the top end finish surface of the storage wall.

この発明によれば、貯槽壁壁面汚損防止構造体の取り外し工程が必要なくなるため、作業効率を大幅にあげることができる。   According to this invention, since the removal process of the storage wall surface wall contamination prevention structure is not required, the working efficiency can be greatly improved.

上記の構成の場合の排水パイプは前記金属製屋根材上を流れ該金属製屋根材下部と前記貯槽壁壁面汚損防止構造体とで形成される溝に溜まる雨水を外側に排出するためのものとすることもできる。   The drainage pipe in the case of the above configuration flows on the metal roofing material and discharges the rainwater accumulated in the groove formed by the metal roofing material lower part and the storage tank wall surface wall contamination preventing structure to the outside You can also

この発明によれば、排水パイプにより汚れた雨水は貯槽壁の壁面を流れ落ちることがないため、壁面が汚れることがなく、清掃の必要がない。   According to this invention, since the rainwater contaminated by the drainage pipe does not flow down the wall surface of the storage tank wall, the wall surface is not soiled and there is no need for cleaning.

また、上記課題を解決するための本発明は、貯槽壁の天端に設けられ、前記貯槽壁の天端近傍に接続される金属製屋根材の最下端よりも高い位置まで立設され、前記金属製屋根材の前記貯槽壁への接続位置より内側に内壁が所在し、前記貯槽壁の天端真上位置に内外を貫くように排水パイプが埋設可能であるようにコンクリートが打設されて形成される貯槽壁壁面汚損防止構造として実現することができる。   Further, the present invention for solving the above problems is provided at the top end of the storage tank wall and is erected to a position higher than the lowermost end of the metal roofing material connected near the top end of the storage tank wall An inner wall is located inside the connection position of the metal roofing material to the storage tank wall, and concrete is cast so that a drainage pipe can be embedded so as to penetrate inside and outside at a position just above the top end of the storage tank wall It can be realized as a storage wall surface wall contamination prevention structure to be formed.

この発明によれば、汚れ、錆を含んだ雨水が壁面を伝わらないように排水することで壁面の汚れを防止することができる。   According to the present invention, it is possible to prevent the contamination of the wall surface by draining the rainwater containing the dirt and rust so that the rainwater does not travel through the wall surface.

さらに、上記課題を解決するための発明は、貯槽壁の天端近傍で屋根材が接続される受け具上に堰板が立設され、前記立設される堰板の内外を貫通して排水パイプが挿通可能であるように複数の穴が穿設されることを特徴とする貯槽壁壁面汚損防止構造として実現することができる。   Furthermore, according to the invention for solving the above-mentioned problems, a weir plate is erected on a receptacle to which a roofing material is connected in the vicinity of the top end of the storage tank wall, and drainage is conducted through the inside and outside of the weir plate installed. A plurality of holes are bored so that a pipe can be inserted, and it can be realized as a storage wall wall surface contamination prevention structure characterized by the above-mentioned.

この発明によれば、堰板にあらかじめ複数の穴を穿設してあることにより、排水パイプを容易に取り付けることができ、作業工程を簡略化することができる。この場合、堰板は鋼製をもちいることとする。   According to the present invention, the drainage pipe can be easily attached by forming a plurality of holes in the weir plate in advance, and the working process can be simplified. In this case, we will use the steel plate made of steel.

本発明によれば、金属製の屋根材を用いた構造、例えばコンクリート外壁を有する貯槽の建設において、貯槽のコンクリート外壁の汚損問題を解決することができる。さらに、安全性と作業性を格段に向上させつつ、経済効率も格段に向上させることが可能な貯槽構造及び貯槽壁壁面汚損防止構造体が実現される。これにより、貯槽完成前に汚れた貯槽壁のジェットウォッシャーなどの清掃が不要となり、清掃にかなりのコストと時間を要していた現状に対して、根本的な解決策が与えられたこととなる。   ADVANTAGE OF THE INVENTION According to this invention, the fouling problem of the concrete outer wall of a storage tank can be solved in the structure which used the metal roof material, for example, construction of the storage tank which has a concrete outer wall. Furthermore, a storage tank structure and a storage wall surface wall contamination prevention structure are realized which can significantly improve the economic efficiency while greatly improving the safety and the workability. As a result, it becomes unnecessary to clean the dirty storage tank wall before the completion of the storage tank, and a fundamental solution is given to the current situation where the cost and time required for the cleaning are considerable. .
