Abstract

Stand water tank is composed of water tank made of corrosion resistant materials such as FRP, PE, STS, and relatively cheap and durable steel stand. In the case of the ball tank, the steel frame is made of only steel pipe or a-beam, so the price is cheap, but the size of the tank is limited and the strength of the tank itself is weak. Since the cylindrical tank is framed with steel pipe or section steel, and the steel plate is placed on it, the frame is expensive, and the bottom plate of the tank is flat, so it is not completely drained. The present invention is made by convex plate (Convex or Cone) with the lower plate of the cylindrical tank at the bottom, and the abutment around the lower plate as a rim of the cross section. By integrating with the stand, the price of the stand is cheap, there is no limit on the capacity of the tank, and the drainage can be completely drained.

Description

Column Water Tank Onebody with Stand

The present invention relates to a tank and its mount to increase the height of the tank (= water tank) to obtain a suitable supply water pressure.

The tank (= water tank) is usually made of corrosion-resistant materials such as FRP, PE, STS because it is not good for rust. In order to raise the height of the tank to obtain a suitable supply water pressure, the tank stand is made of relatively inexpensive and durable steel. Until now, the tank was simply putting a tank on the mount. The old tank is made of steel pipe or a-beam only according to the tank, so it has the advantage of being cheap and complete drainage. However, since the mold is required for the manufacture of the tank, large tanks are difficult to produce and large bending stress occurs in the tank tank. The strength was also weak, so many defects. Cylindrical tanks were framed with steel pipes or section steels, welded steel plates to form mounts, and then the cylindrical tanks were mounted. Therefore, as the price of the stand was expensive and the diameter of the tank increased, the stand price increased rapidly. This is a serious problem in recent years due to the high steel prices. In addition, the fact that the bottom of the tank is flat and not completely drained was a common weakness of all cylindrical tanks.

The present invention aims to eliminate the weaknesses of the old and cylindrical tanks, combining only the advantages, and extending the life of the mount, making the construction convenient, and reducing the overall price.

The design of this invention is to make the lower plate of the cylindrical tank into the convex plate shape at the bottom similar to the spherical tank, and to fix the steel frame made of the section steel inside the frame of the cross section of the a cross section of the a cross section consisting of a horizontal frame and a vertical frame. By joining the steel column to the lower part of the steel frame, the tank and the stand are integrated to provide the stand tank with all the advantages of the old tank and the cylindrical tank. .

The present invention adds the advantages of the cylindrical tank and the long life of the mount on top of the advantages of the old tank.

The advantages of the cylindrical bath are as follows.

① The strength structure of the tank is excellent and large size can be manufactured.

② If the top plate is a flat plate, it is convenient for people to climb on the tank board or install a sterilizer.

The disadvantages of the cylindrical bath are as follows.

① It is impossible to drain completely because the bottom plate is flat. Sediment discharge (self-cleaning) is also impossible.

② When the frame is needed, the frame is expensive because we make the frame by weaving the frame and laying the steel plate. In particular, the larger the diameter of the tank, the faster the price of the mount. In particular, steel prices are high in recent years, and the stand prices are more problematic.

The advantages and disadvantages of a spherical tank are the opposite of a cylindrical tank.

The disadvantage is

① Strength structure is weak, mold is necessary for manufacturing, and large size is difficult to manufacture.

② The top plate is convex upward, making it difficult to climb on the top plate.

Advantage

① The lower part is convex and it has the function of complete drainage and self-cleaning.

② The price of the frame is cheap because the frame is made of only the section steel or steel pipe.

This design makes ① large water tank easy to manufacture ② ② top plate can be flat plate ③ bottom plate is convex downward for complete drainage and self-cleaning ④ mount frame is made of only section steel It has the advantage of structure. There are many other advantages as well. Corrosion resistance Lower plate (1cb) protects the iron frame (2) is the longest life of the iron frame (2), the most important part of the mount, and does not melt. Even when the column is fixed by bolt fastening, all of the column fixing bolts and nuts 4 are also inside the lower plate frame 1cb to be protected from wind and rain.

The iron frame bolts and nuts (3a and 3b) are convenient when transporting and constructing the water tank (1) and the frame iron frame (2) integrally, and prevent the water-free tank from flying in the gust. The strength of the iron frame (2) may be slightly supplemented, and may also serve as a fixation of the ladder (6). The stand is made of only steel or steel pipes as the old tank, but the iron frame of the old tank directly touches the copper of the tank, causing a large bending stress on the copper of the tank, making the old tank vulnerable and not protecting the iron frame from the storm.

The iron frame 2 of the present invention generates some bending stress in the water tank lower plate 1cb and does not generate special additional stress in the water tank 1a. The water tank lower plate (1c), unlike the ordinary cylindrical water tank with almost no stress is generated a large stress, but because the membrane stress is not unacceptable level.

Disadvantages due to the large stress generated in the tank bottom plate (1c) of the present invention is largely offset by the benefits of the absence of the top plate and the benefits of the complete drainage and sediment self-cleaning function due to the plate-like structure. This is the key effect of the present invention.

Large bending stresses are also generated in the steel frame itself, and the section steel frame (2) has a sufficient cross-sectional coefficient to cope with this bending even at a low price. Since the iron frame web 2a only bears the shear force, the iron frame bolt hole 2c drilled in the iron frame web 2a hardly reduces the strength of the iron frame 2. Care should be taken because the strength of the iron frame is greatly reduced when a hole is drilled in the iron frame web 2b in which soft stress occurs. If the water tank is so large that the section coefficient of the steel frame (2) is insufficient, ① increase the number of iron frame bolts and nuts (3) to compensate for the lack of section steel with the strength of the tank (1a), or ② the number of columns. Increase or ③ install several stiffeners between pillars and steel frames. ③ is probably the most economical.

The bolt clamp column assembly method is very easy to install and is particularly suitable for small and medium tanks or temporary tanks with relatively low mount heights. Even a large tank provides great convenience for construction work.

The basic use of the present invention can be widely used in water tanks (= water tanks), chemical tanks, chemical reaction tanks, grain tanks, feed tanks, and the like.

The copper 1a and the upper plate 1b and the upper manhole 1ba of the tank 1 of the present invention are not different from the copper and the upper plate of the cylindrical tank. However, the lower plate 1c forms a plate-shaped center 1ca with its center portion convex downward, and the lower plate 1c forms a lower plate frame 1cb around the lower plate frame 1cb, which is the lower plate horizontal frame 1cba and the lower plate vertical frame (1c). 1cbb).

(할구형=Convex형) 또는

(원추형=Cone형)이 된다. 접시형 하판 중앙(1c)를 원추형으로 하면 침전물 제거에는 유리하나 주위에 큰 응력이 발생하는 등 강도에서 불리하다. 그러나 높고 뾰족한 예각원추가 되면 주위응력은 큰 문제가 안되는데 이것은 수조전체 높이가 높아져 수조로는 적합하지 못하나 곡물탱크나 침전조 등의 용도로는 적합할 수 있다.Therefore, the vertical section of the bottom plate

(Volume type = Convex type) or

(Cone type = Cone type). If the plate-shaped lower plate center 1c is conical, it is advantageous for removing the precipitate, but it is disadvantageous in strength, such as generating a large stress around it. However, if the high and sharp acute cone is not a big problem, the surrounding stress is not a big problem. This is not suitable as a tank because the height of the entire tank is high, but may be suitable for use in grain tanks and settling tanks.

The mouthpiece is low in height and relatively even in stress, which is advantageous for the water tank. The tank 1a of the tank is joined on the lower plate horizontal frame 1cba, but the bonding position may be anywhere on the horizontal frame 1cba.

3-1 shows a case in which the copper 1a is joined to the outermost edge of the horizontal frame so that the copper 1a and the vertical frame 1cbb are integrated, and FIG. 3-2 shows the copper 1a inside the horizontal frame 1cba. It is a case where the a-shaped lower plate frame 1cb is joined and protrudes from the copper 1a.

The iron frame 2 is fixed to the bolt-nut 3 in the a-type lower plate frame 1cb. The steel frame (2) can be made of K-beam (= square tube), a-beam, c-beam (including C-beam), H-beam, flat iron, etc., but the a-beam can be used only in small tanks because of the small section coefficient. ㅁ Shape steel (= square tube) is slightly disadvantageous for bolting, but it is suitable for joining steel pipe columns, so it is suitable for small and medium tanks.

The c section steel is suitable for large tanks due to its large section modulus. However, because the width of the lower flange (2bb) to join the column 4 is narrow, a reinforcement is necessary. In the case of the c-section steel frame, the steel frame web (2a) is rolled to the outside and completed by welding. The web 2a of the iron frame is as close as possible to the inside of the vertical frame 1cbb, and the upper edge of the iron frame 2ba is adhered to the lower part of the horizontal frame 1cba, and then a hole penetrating the vertical frame 1cbb and the iron frame web 2a. Drill several (1cc, 2ac) and fix it with the bolt 3a and the nut 3b.

The bolt 3a and the nut 3b are preferably made of a corrosion resistant material such as STS. At least two bolts and nuts are required, and the bolts and nuts are integrated into the tank (1) and the mount to prevent the tank from blowing in the wind, and to transport the tank (1) and the iron frame (2) at the same time. By combining the strength of the iron frame (2) and also serves to reinforce the strength of the iron frame (2). As the number of bolts and nuts increases, this role also increases, but costs increase, which is unnecessary unless it is a special case. Bolts and nuts are also a great help for field installation. Moreover, when penetrating integrally with the ladder 6, it is effective also to fix the ladder 6.

Thus, the tank 1 and the iron frame 2 are integrated, and then the mount column 4 is welded to the lower flange 2bb of the iron frame 2 to complete the mount tank.

In the case of a-beam steel frame, there is no lower flange, so the pillar pillar (4) should be directly welded to the upper flange (2ba).

In the case of rectangular steel frame, there are two webs (2aa, 2ab), so it is necessary to drill holes through both webs and fasten bolts and nuts (3). If this fastening is too strong, the tube may be deformed and the strength may be affected. This is not a problem with the C and A steel frames.

When the steel frame 2 is made of H-shaped steel, the water tank vertical frame (1cba) and the web (2a) of the steel frame is not in close contact with each other, so it is more disadvantageous than the square tube to fasten the bolt (3a). However, large tanks with large cross-sectional coefficients can be used for large tanks that require large cross-sectional coefficients because bolt fastening is not important.

In the case of making a steel frame (2) with flat steel, there is no flange, so the column must be welded directly to the steel frame web. The flat steel has a good cross-sectional coefficient, but the number of iron frame bolts (3) is increased to prevent buckling. ) There are many disadvantages such as the height is too high, it is inconvenient to weld the column, and excessive eccentric load acts on the column. Instead of welding the column 4 directly to the iron frame 2, the pillar fitting tube 4b may be welded to the iron frame 2, and the pillar 4a may be inserted into the pillar fitting tube 4b. Thereafter, there is also a method of welding the nut 4cb to the post 4a or the post fitting tube 4b in advance without welding or final finishing, and then tightening the bolt 4ca at the site. 4-1, 4-2) It is a widely used technique when assembling tent frame. However, the strength of installation of the sink is low, but it is very convenient and usually does not interfere in practical use. Of course, bolt clamping and welding can be used together. If the post fitting tube 4b is larger than the post 4a as shown in Fig. 4-1, the nut 4cb should be welded to the post fitting tube 4b, and the post fitting tube 4b is shown as Fig. 4-2. If it is smaller than the diameter of 4b), the nut 4cb should be welded to the column 4a and bolted. If the height of the column 4 is increased, it is inevitable to reinforce the horizontal reinforcement (5). In this case, it is convenient to manage the discharge valve 7 by providing an intermediate scaffold with a flat steel plate or the like in the horizontal reinforcement 5 below about 1.8 m from the lower plate 1c.

If there is a lower manhole 1cd as shown in Fig. 3-2, the lower manhole 1cd can also be managed. The lower manhole (1cd) is convenient for cleaning the tank, but expensive.

Piping connection of the tank of the present invention can be made in the upper and lower portions of the copper 1a as in the general cylindrical water tank, or in the dish-shaped lower plate 1c as in the spherical water tank. In any case, however, the drain valve 7 must be installed at the center of the bottom plate 1c to be completely drained and is effective for deposit discharge (= self-cleaning). If there is a lower manhole (1cd) will install a discharge valve (7) in the center of the lower manhole cover.

Care should be taken in the strength of the lower plate 1c when connecting pipes to the lower plate 1c. Because the greatest stress is generated in the lower plate, if you drill holes roughly, there is a risk of defects. Therefore, flange connection is safer than socket connection.
