Description

本発明は、覆蓋構造体および覆蓋方法に係り、特に、上下水道施設、集落排水施設等の水処理設備の上部開口部における異物の混入防止および臭気拡散防止手段として有用な覆蓋構造体および覆蓋方法に関する。   The present invention relates to a cover structure and a cover method, and in particular, a cover structure and a cover method useful as a means for preventing foreign matter from mixing and preventing odor diffusion in an upper opening of water treatment facilities such as water and sewage facilities and village drainage facilities. About.

水処理施設としての沈殿池や反応槽の上部開口部には、異物の混入防止、臭気の拡散防止、作業環境の改善・安全対策等を目的として覆蓋を施すことが望ましいとされ、従来から、例えばRC(鉄筋)コンクリート、アルミニウム鋼板、またはガラス繊維強化プラスチック(FRP)からなる覆蓋構造体が採用されているが、これらの覆蓋構造体には、設備重量が大きく、工事が煩雑で、施工費用が高額であるという問題があった。   It is desirable to cover the sedimentation basin as a water treatment facility and the upper opening of the reaction tank for the purpose of preventing the entry of foreign substances, preventing the spread of odors, improving the work environment, and taking safety measures. For example, cover structures made of RC (steel) concrete, aluminum steel plate, or glass fiber reinforced plastic (FRP) are used. These cover structures are heavy in equipment weight, complicated in construction, and costly. There was a problem that was expensive.

一方、鉄骨トラス構造を用いない、エアーチューブ方式の覆蓋構造体は、軽量であるが、各種形状に加工することが困難であって適用範囲が限定されるうえ、チューブの空気圧管理、コンプレッサーの維持管理等が煩雑になるとう問題があり、これら従来の覆蓋構造体を、敷地面積が著しく大きい、例えば沈殿池等に適用することは、困難であった。   On the other hand, the air tube cover structure that does not use a steel truss structure is lightweight, but difficult to process into various shapes and has a limited scope of application, as well as managing the air pressure of the tube and maintaining the compressor There is a problem that management and the like become complicated, and it has been difficult to apply these conventional cover structures to a pond having a remarkably large site area.

そこで近年は、特殊形状の覆蓋対象構造物または開口面積の大きな覆蓋対象構造物に対しても、容易に施工することができる、安価、軽量な覆蓋構造体、または屋根構造体としてシート状物をワイヤーで支持する構造の覆蓋または屋根構造体の開発が行われている。   Therefore, in recent years, sheet-like objects can be easily applied to a specially shaped cover object structure or a cover object structure having a large opening area, and can be easily constructed as a cheap and light cover structure or roof structure. Development of a cover or roof structure with a wire-supported structure is underway.

図10は、従来のシート状物からなる屋根構造体を示す説明図である。図10において、この屋根構造体101は、例えば四角形状の床部102の各頂点に配設された柱103と、前記床部102の対角線上に対向する二組の柱103、103間にそれぞれ架設された下ワイヤー104、104と、該下ワイヤー104上に葺かれたシート状の屋根材105と、該屋根材105の各角部を前記下ワイヤー104に固定する図示省略したクリップと、前記屋根材105の上部であって、前記下ワイヤー104に沿ってその左右両側に掛け渡された左右一対の上ワイヤー106とから主として構成されている。   FIG. 10 is an explanatory view showing a conventional roof structure made of a sheet-like material. In FIG. 10, the roof structure 101 includes, for example, a column 103 disposed at each vertex of a quadrangular floor portion 102 and two pairs of columns 103 and 103 facing diagonally of the floor portion 102. The lower wires 104, 104 installed, a sheet-like roof material 105 wound on the lower wire 104, clips not shown for fixing the corners of the roof material 105 to the lower wire 104, and The upper part of the roofing material 105 is mainly composed of a pair of left and right upper wires 106 that are stretched along the lower wire 104 on both left and right sides thereof.

しかしながら、上記従来技術は、シート状屋根材105が、上下のワイヤー104と106とで挟持するように支持されているので、下からの吹き上げ荷重に対する耐性を有しているものの、これをそのまま水道処理設備の覆蓋構造体として適用すると、前記シート状屋根材の端部を覆蓋対象構造物の開口周縁部に当接して開口部全体を閉鎖的に覆うことが困難となり、シート状物と開口周辺部との間に隙間が生じ、該隙間から設備内に異物が混入したり、設備内の臭気がそのまま自由に外部まで拡散するという問題があった。
特開平09−078683号公報 特開2002−081135号公報 特開2002−088895号公報 特開2002−242217号公報
However, since the above-mentioned prior art is supported so that the sheet-like roof material 105 is sandwiched between the upper and lower wires 104 and 106, the sheet-like roof material 105 has resistance against a blowing load from below, but this is used as it is. When applied as a cover structure of a processing facility, it becomes difficult to cover the entire opening portion in a closed manner by contacting the edge of the sheet-like roofing material with the peripheral edge of the opening of the cover target structure. There is a problem that a gap is formed between the unit and foreign matter is mixed into the equipment from the gap, or the odor inside the equipment is freely diffused to the outside as it is.
