本考案は円形槽、特に下水処理場の円形処理槽
に載置する軽金属製の防臭蓋に関するものであ

によりリブｃ，c′の長さｌと角θを計算して作製
した専用の成形型を用いて製造している。 Generally, in a sewage treatment plant, sewage is agitated using a circular treatment tank, and this circular tank is equipped with a lid for danger prevention and odor prevention. Conventionally, a resin-molded lid with excellent moldability has been used for the lid of such a circular tank. For example, as shown in Fig. 1A, reinforcing ribs c, Using a resin panel a with a concrete fixing flange d on the fan-shaped side c' and a fan-shaped side, a plurality of resin panels a (the figure shows a case of 12 pieces) are attached in a circular Mounting stand 2 installed in the center of tank 1
A conical odor-proofing lid is formed by placing them next to each other around the periphery of the circular tank 1. The resin panel a of the deodorizing lid is manufactured using a special mold which is prepared by calculating the length l and angle θ of the ribs c and c' according to the size of the circular tank 1.
従つて円形槽の防臭蓋を形成するためには、槽

ものではなかつた。 Therefore, in order to form an odor-proofing lid for a circular tank, it is necessary to prepare several types of molds depending on the size of the tank, which causes an increase in the cost of the odor-proofing lid. Furthermore, resin panels are weak in strength and may break if someone rides on them, so they are not effective in preventing danger.

を特徴とするものである。 With this in mind, as a result of various studies, we have developed a lightweight metal lid that is strong, easy to install, and inexpensive. One or more light metal joists with flanges are mounted in parallel, and light metal hollow cover plates are placed on the periphery of the circular tank and on the flange of the joists, arranged at right angles to the joists. It is characterized by:
これを図面を用いて詳細に説明する。 This will be explained in detail using the drawings.

断したものである。 Figure 2 shows an embodiment of the light metal lid of the present invention, in which 1 is a circular tank, 3 is a step provided around the upper end of the circular tank 1, 4 is a light metal joist, and 6
shows a hollow lid plate made of light metal, in which two light metal joists 4 are mounted parallel to each other between steps 3 provided around the upper end of the circular tank 1. As shown in FIG. 3, the light metal joist 4 is provided with flanges 5 for placing a lid on both sides in the longitudinal direction, and is cut from a long piece of material, such as an extruded piece, to fit the tank 1. be. Between the upper end of the tank 1 and the light metal joists 4 and both joists 4
In between, a large number of hollow cover plates 6 made of light metal are arranged and spanned at right angles to the joist material 4, and placed on the flange 5 of the joist material 4 and the upper end of the tank 1. The light metal hollow lid plate 6 is hollow as shown in FIG. 4, and is cut from a long piece of material, such as an extruded piece, to fit between the upper end of the tank 1 and the light metal joist 4 and between both joists 4. It is something.

とよい。 The light metal lid of the present invention has the above-described structure, and the joists and lid plate are made of light metal, which is much stronger than conventional resin panels, improving the strength of the entire lid. In particular, if you want to increase the strength of the entire lid, you can increase the number of joists to shorten the length of the lid plate, or/and install a joist in the hollow part of the lid plate 6 as shown in FIG. It is preferable to provide one or more reinforcing ribs 7 in the longitudinal direction.

を奏するものである。 In addition, the light metal lid of the present invention can be formed using the light metal joists and lid plates used for conventional square tanks, and in particular can be formed using one type of joist for circular tanks of various sizes. Since it can be constructed using one type of material for wood and one type of material for the lid plate, it not only becomes significantly easier to construct, but also has remarkable effects such as reducing costs compared to conventional resin lids. It is something.
