Description
本考案は、建設コストが低く保守点検が便利な矩形鋼製水槽の内部補強構造に関する。 The present invention relates to an internal reinforcing structure of a rectangular steel water tank that is low in construction cost and convenient for maintenance and inspection.
図3に示すように、従来、配水池や受水槽等のような大容量の矩形鋼製水槽1は、受圧側壁1a、1bの厚みが薄くて単独に水平方向の水圧荷重に対抗できないので、両端部を対向の受圧側壁に連結する水平補強バー2を設置する内部補強構造が従来から採用されている。この場合、水槽1の対向の受圧側壁1a、1bは、一体となって、大きさが同様であるが向きが反対の水圧荷重を受けて安定する。 As shown in FIG. 3, conventionally, a large-capacity rectangular steel water tank 1 such as a distribution reservoir or a water receiving tank has a thin pressure receiving side wall 1a, 1b and cannot independently resist a horizontal hydraulic pressure load. Conventionally, an internal reinforcing structure in which horizontal reinforcing bars 2 that connect both ends to opposing pressure-receiving side walls is installed. In this case, the opposing pressure-receiving side walls 1a and 1b of the water tank 1 are integrated and stabilized by receiving a hydraulic load having the same size but the opposite direction.
しかし、水槽の容量が大きくなった場合、上記の従来技術には下記のデメリットがある。 However, when the capacity of the water tank is increased, the above-described conventional technology has the following disadvantages.
水平補強バー2は水槽本体1の深さの増加につれてその本数が多くなったり水槽本体1の幅の増加につれてその延長が長くなったりして、加えて水平補強バー2を支えるための鉛直バー3を多数に設置する必要があるので、水槽の材料費と建設費が高額になるばかりでなく、水槽1内において水平補強バー2と鉛直バー3が密集して、水槽の保守・点検等のための作業性が悪くなる。 The number of the horizontal reinforcing bars 2 increases as the depth of the water tank body 1 increases, and the length of the horizontal reinforcing bars 2 increases as the width of the water tank body 1 increases. In addition, a vertical bar 3 for supporting the horizontal reinforcing bar 2 As a result, it is necessary not only to increase the material cost and construction cost of the aquarium, but also because the horizontal reinforcement bar 2 and the vertical bar 3 are densely packed in the aquarium 1, for maintenance and inspection of the aquarium. The workability of becomes worse.
配水池、受水槽等のような大容量矩形鋼製水槽は、敷地形状の対応性に優れ、加えて耐震性、美観、衛生性、フリーメンテナンス性など多くのメリットが評価されて公共施設として加速的にその実績が伸びている一方、安全性とコスト削減が求められている。従ってより安全且つ合理的な内部補強構造を考案して建設コストを抑えるのが至急な課題となっている。 Large-capacity rectangular steel tanks such as reservoirs, receiving tanks, etc. are excellent in terms of site shape, and in addition, many merits such as earthquake resistance, aesthetics, hygiene, free maintenance are evaluated and accelerated as public facilities While the results are growing, safety and cost reduction are required. Therefore, it is an urgent task to devise a safer and more rational internal reinforcement structure to reduce the construction cost.
上記問題を解決するため、請求項1に記載の考案は、図1と図2に示すように、矩形水平断面を有する鋼製水槽の内部において、対向の受圧側壁1a、1bの内側に受圧側壁1a、1bの補強を目的とする、水平バー4aと鉛直バー4bと傾斜バー4cから構成する縦型組立トラス梁4が設置されることを特徴とする内部補強構造を用いることを要旨とする。 In order to solve the above-mentioned problem, as shown in FIGS. 1 and 2, the device according to the first aspect of the present invention includes a pressure-receiving side wall inside the opposing pressure-receiving side walls 1a and 1b in a steel water tank having a rectangular horizontal cross section. The gist of the present invention is to use an internal reinforcing structure characterized in that a vertical assembly truss beam 4 composed of a horizontal bar 4a, a vertical bar 4b, and an inclined bar 4c is installed for the purpose of reinforcing 1a and 1b.
請求項2に記載の考案は、請求項1に記載の水槽の内部において、図1に示すように、天井板1cの直下に天井板1cの受ける積載・積雪荷重を支えるための、鉛直バー8aと水平バー8bと傾斜バー8cから構成する横型組立トラス梁8が設置されることを特徴とする内部補強構造を用いることを要旨とする。 As shown in FIG. 1, the device described in claim 2 is a vertical bar 8a for supporting a load / snow load received by the ceiling plate 1c immediately below the ceiling plate 1c, as shown in FIG. The gist of the invention is to use an internal reinforcing structure in which a horizontal assembly truss beam 8 composed of a horizontal bar 8b and an inclined bar 8c is installed.
請求項3記載の考案は、請求項1に記載の水槽の内部において、図2に示すように、天井板1cの受ける積載・積雪荷重を支えるための、柱材と称する鉛直バー5、7と、これら5、7と交差する梁材と称する水平バー6が設置されることを特徴とする内部補強構造を用いることを要旨とする。 As shown in FIG. 2, the invention described in claim 3 includes vertical bars 5 and 7 called column members for supporting the load / snow load received by the ceiling plate 1 c, as shown in FIG. 2. The gist is to use an internal reinforcing structure characterized in that a horizontal bar 6 called a beam that intersects with these 5 and 7 is installed.
本考案の最大の特徴は、図3に示す従来の内部構造方式と異なって、水槽本体1内に水平補強バー2の設置がなく、すなわち水槽本体1の対向の受圧側壁1a、1bの連結がない、いわゆる壁自立型の矩形鋼製水槽の内部補強構造である。この内部補強構造は、水槽、特に大容量水槽の構築に必要とする部材総重量を大幅に減らし、加えて図3に示す従来の水平バー2と鉛直バー3の交点の溶接作業を必要にしないので、材料費と施工費の両方面から、水槽建設のコスト低減を可能とする。 The greatest feature of the present invention is that, unlike the conventional internal structure system shown in FIG. 3, there is no horizontal reinforcing bar 2 in the aquarium body 1, that is, the connection of the pressure-receiving side walls 1a, 1b facing each other. There is no so-called wall self-supporting rectangular steel tank internal reinforcement structure. This internal reinforcement structure greatly reduces the total weight of members required for construction of a water tank, particularly a large-capacity water tank, and does not require welding work at the intersection of the conventional horizontal bar 2 and vertical bar 3 shown in FIG. Therefore, it is possible to reduce the cost of water tank construction in terms of both material costs and construction costs.
また、図3に示す従来の水平バー2と鉛直バー3の密集な配置がなくなって、水槽本体1内部に開放感があり、水槽の保守・点検等のための作業性の大幅の改善を期待することができる。 Also, the dense arrangement of the conventional horizontal bar 2 and vertical bar 3 shown in FIG. 3 is eliminated, and there is a sense of openness inside the aquarium body 1, which is expected to greatly improve workability for maintenance and inspection of the aquarium. can do.
図1に考案を実施するための最良の実施形態を示す。 FIG. 1 shows the best mode for carrying out the invention.
図1に示すように水槽本体1の対向の受圧側壁1a、1b際に、受圧側壁1a、1bを補強する縦型組立トラス梁4が設置され、片側の受圧側壁1aでも水圧荷重に抵抗できるよう、縦型組立トラス梁4の諸部材4a、4b、4cが設計される。 As shown in FIG. 1, a vertical assembly truss beam 4 that reinforces the pressure-receiving side walls 1a and 1b is installed on the opposite pressure-receiving side walls 1a and 1b of the water tank body 1, so that the pressure-receiving side wall 1a on one side can resist the hydraulic load. The members 4a, 4b, 4c of the vertical assembly truss beam 4 are designed.
天井板1cの直下に、天井板1cを補強する横型組立トラス梁8が設置され、天井積載・積雪荷重に抵抗できるよう、横型組立トラス梁8の諸部材8a、8b、8cが設計される。 A horizontal assembly truss beam 8 that reinforces the ceiling plate 1c is installed directly below the ceiling plate 1c, and the members 8a, 8b, and 8c of the horizontal assembly truss beam 8 are designed so that they can resist ceiling loading and snow load.
上記の内部補強構造を有する水槽では、水が入った場合、縦型組立トラス梁が水圧荷重に対抗し横型組立トラス梁が天井の積載・積雪荷重に対抗して水槽の安全性が確保される。 In the water tank having the above internal reinforcement structure, when water enters, the vertical assembly truss beam resists the hydraulic load and the horizontal assembly truss beam resists the ceiling loading / snow load, ensuring the safety of the tank. .
本考案の実施例1は、図1に示すように、本考案を実施するための最良の実施形態である。 Example 1 of the present invention is the best mode for carrying out the present invention, as shown in FIG.
本考案の実施例2は、図2に示すように、実施例1の横型組立トラス8の代わりに、鉛直バー5、7と、これら(5、7)と交差する水平バー6を設置するものである。 In the second embodiment of the present invention, as shown in FIG. 2, instead of the horizontal assembly truss 8 of the first embodiment, vertical bars 5 and 7 and a horizontal bar 6 intersecting these (5, 7) are installed. It is.
