Description

Column Type Water Tank Onebody with Stand}

The present invention relates to a water tank for raising a height of a water tank (water tank) to obtain a suitable supply water pressure, and a stand (stand) configured integrally with the water tank while supporting the water tank.

Water tanks are usually made of corrosion-resistant materials such as FRP, PE and STS, since it is natural that corrosion or rust does not occur. The tank stand is made of relatively inexpensive and sturdy steel to increase the height of the tank to obtain a suitable supply pressure. So far, pedestal tanks have simply been placed on top of the pedestal.
The spherical water tank has the advantage of being cheap and complete drainage because the pedestal is made of steel pipe or a-beam according to the water tank. The strength of the tank itself was also weak, so there were many defects.
Cylindrical water tank is composed of steel pipe or section steel frame, welded steel plate on it to construct a pedestal, and then a cylindrical water tank. Therefore, the price of the pedestal increased rapidly, especially as the cost of the pedestal increased. 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 eliminates the weaknesses of the old tank and the cylindrical tank and combines only the advantages, in addition to the purpose of extending the life of the pedestal, convenient construction and to provide a low overall cost of the pedestal and the tank combined.

The present invention is made of a steel reinforcement bar made of a section steel inside the lower plate reinforcement of the a-shaped section by reinforcing the lower plate of the cylindrical tank into a convex plate shape at the bottom similar to the spherical tank, and reinforcing the lower plate around the lower section reinforcement of the 'a' section consisting of the horizontal and vertical sections. By fixing the bottom plate reinforcement and bolt of the cross-section and joining the steel column to the bottom of the steel reinforcement, the tank and the pedestal are integrated so that the cost of the pedestal is low, the capacity of the water tank is not limited, and it is completely drained. It is characterized in that to provide a tank integral with the pedestal having all the advantages of the cylindrical tank.

The present invention combines the advantages of a cylindrical tank and the advantages of a spherical tank in addition to the advantages of a very long life of the pedestal.

The advantages of the cylindrical bath are as follows.

① The price is cheap

② The strength structure of the water tank is excellent and large size can be produced.
③ If the top plate is a flat plate, it is convenient for a person to work on the top plate of a tank 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. Therefore, the natural discharge (self-cleaning) of the sediment is also impossible.

② If the pedestal is needed, the frame is expensive because the frame is woven with steel and the steel sheet is made. In particular, the larger the tank diameter, the faster the cost of the pedestal. In particular, steel prices are high in recent years, the pedestal price becomes even more problematic.

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

The disadvantage is

① The price is expensive
② The strength structure is weak and mold is necessary for manufacturing, and large size is difficult to manufacture.

③ The top plate is convex upward, making it difficult to climb on the top plate.

Advantage

① The lower part is convex downward for easy draining and self-cleaning.

② The pedestal price is cheap because only pedestal or steel pipe is used to make the pedestal.

This design makes ① large water tank easy to manufacture, ② top plate can be flat plate, ③ bottom plate is convex, and it can be completely drained and self-cleaned. ④ pedestal is made of steel only. It has the advantage of structure. There are many other advantages as well. Corrosion resistance (type A) The lower plate reinforcement (4) protects the steel reinforcement (2), the life of the steel reinforcement (7), the most important part of the pedestal is long and no rust. Even when fixing the column by bolt fastening, all of the column fixing bolts and nuts 13 are also located inside the lower plate reinforcement bar 4 to be protected from weather.

The bolt and nut 10 is convenient when transporting and constructing the tank and the pedestal and the steel reinforcing bar 7 integrally, and prevents the water-free tank from blowing in the gust and withstands vibration during an earthquake. The strength of the steel reinforcing bar may be slightly supplemented, or may also serve as the fixing of the ladder 11. Although the pedestal is made of only steel or steel pipe, it is the same as the old water tank, but the steel reinforcement bar of the old water tank directly touches the body of the water tank, causing a large bending stress on the water body of the water tank, so the old water tank is weak and the steel reinforcement steel is not protected from the weather. .

The steel reinforcing bar 7 of the present invention generates some bending stress in the tank bottom plate reinforcing bar 4 and does not generate special additional stress in the body 1 of the tank. The lower plate 3 of the tank has a large stress unlike the usual cylindrical tank with little stress, but due to the plate-like structure, only the stress due to the tensile stress can be adequately handled.

Disadvantages due to the large stress generated in the tank bottom plate 3 of the present invention is largely offset by the benefits of the bottom plate and the benefit of the complete drainage and sediment self-cleaning function due to the plate-like structure. This is the key effect of the present invention.

The steel reinforcement itself generates a large bending stress and a relatively small torsional stress. The steel reinforcing steel reinforcement 7 has a cross-sectional coefficient sufficient to resist such bending even at a low price. Since the reinforcing bar web 7b bears only shear force, the reinforcing bar bolt hole 7c drilled in the reinforcing bar web 7b hardly reduces the strength of the reinforcing bar 7. Care should be taken that drilling holes in the upper and lower flanges 7a of the steel reinforcement greatly reduces the strength of the steel reinforcement. If the tank is very large and the section modulus of the steel reinforcing bar 7 is insufficient, ① increase the number of the steel reinforcing bar bolts and nuts 3 to compensate for the lack of section steel with the strength of the tank body 1, or ② It is solved by increasing the number of columns, or by installing several warp stiffeners between the columns and the steel reinforcing bars.
The steel reinforcement bar does not need to worry about the torsion because the torsional section coefficient is large, but other C-beams, a-beams, H-beams, and flat plates are all vulnerable to torsion. C- or H-beams can counteract the torsion by making the part with large torsional stresses partially made of square tubes or by welding ribs.

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

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

The body 1, the upper plate 2, the upper manhole 5 and the like of the tank of the present invention have a configuration similar to that of a known cylindrical cylinder. However, the lower plate (3) is a plate-shaped convex down the center and the edge of the lower plate constitutes a type a lower plate reinforcement (4), a type lower plate reinforcement (4) is composed of a horizontal reinforcement (4a) and a vertical reinforcement (4b) do.

Therefore, the vertical section of the lower plate becomes (semi-spherical; Convex type) or (conical; Cone type). When the plate-shaped lower plate 3 is conical, it is advantageous for removing the precipitate, but disadvantageous in strength, such as a large stress generated around it. However, if the high and sharp acute cone is not a big problem, the surrounding stress is not a big problem.

The hemispherical shape has a low height and relatively even stress, which is advantageous for the water tank. The tank body 1 is joined on the horizontal reinforcing portion 4a, but the joining position may be anywhere on the horizontal reinforcing portion 4a.

3A shows the case where the body 1 is joined to the outermost part of the horizontal reinforcement part so that the body 1 and the vertical reinforcement part 4b are integrated, and FIG. 3B shows that the body 1 is joined inside the horizontal reinforcement part 4a. If the a-type lower plate reinforcement (4) protrudes than the body (1).

The steel reinforcing bar 7 is fixed to the a-type lower plate reinforcing plate 4 with bolts and nuts 10. The steel reinforcing bar (7) can be made of ㅁ section steel (angle pipe), a section steel, c section steel (including C section steel), H section steel, flat steel, etc., but the a section steel can be used only in small tanks because of the small section coefficient. ㅁ Shape steel is slightly disadvantageous for bolting, but has a large bending cross section coefficient and torsion cross section coefficient and is suitable for joining steel pipe columns.

The c section steel is suitable for large tanks due to its large section modulus. However, since the width of the lower flange 7a to which the pillar 8 is to be joined is narrow, a reinforcement is necessary. It is also vulnerable to torsion, which may require reinforcement even in areas of high torsion. As described above, the steel sheet is attached to a part of the c-section steel to partially form the K-beam or ribs.
The steel reinforcing bar is completed by rolling the steel reinforcing bar web (7b) to the outside (see Fig. 3a). The web (7b) of the steel reinforcing bar is closely adhered to the inside of the lower plate vertical frame (4b). The flange 7a of the upper part of the steel reinforcing bar is brought into close contact with the bottom of the lower plate horizontal frame 4a, and then several holes 4c and 7c penetrating the vertical reinforcing part 4b and the steel reinforcing bar web 7b are drilled into bolts and nuts ( 10).

The bolt and nut 10 may be made of a corrosion resistant material such as STS. At least two bolts and nuts are required.The bolts and nuts 10 are integrated with the water tank and the pedestal to prevent the water tank from blowing in the wind, to prepare for vibration during an earthquake, and to conveniently transport the water tank and the steel reinforcing bar 7 at the same time. By combining the strength of the tank body (1) and the strength of the steel reinforcement (7) also serves to reinforce the strength of the steel reinforcement (7) somewhat. As the number of bolts and nuts increases, this role increases, but costs increase, which is unnecessary unless it is a special case. Bolts and nuts 10 are also very helpful for field installation work. Moreover, when penetrating integrally with the ladder 11, it is also effective in fixing the ladder 11.

Thus, the tank and the reinforcing bar 7 are integrated, and then the pedestal column 8 is welded to the flange 7a of the lower bar of the reinforcing bar 7 to complete the bath in which the pedestal is integrated.

In the case of the square tube (ㅁ beam) steel reinforcing bar, as shown in Figure 3b, two webs (7b) should be drilled through the holes through both webs and fastening bolts and nuts (10). If this fastening is too strong, the tube may be deformed and the strength may be affected. This is not a problem in the C and A steel reinforcing bars. However, each tube has a large cross-sectional coefficient and is torsionally suitable for steel reinforcing bars.

If the steel reinforcing bar (7) is made of H-shaped steel (standing in the form of I) as shown in Figure 4a, it is vulnerable to torsion and the vertical reinforcing part (4b) and the web (7b) of the steel reinforcing bar section steel is not in close contact with the bolt and nut (10) It is more disadvantage than the tube to fasten. However, large tanks with large cross-sectional coefficients can be used for large tanks that require large steel reinforcement cross-sections because they are torsional torsion because bolt fastening is not important.

Since the steel reinforcing bars (7) are made of flat steel (flat plate), there is no flange, so the column must be welded directly to the steel reinforcing steel web. The flat steel has a good bending cross-sectional coefficient, but the steel reinforcing bar bolts and nuts to prevent buckling and torsion The number of (10) increases, the height of the vertical reinforcement (4b) is too large, it is also inconvenient to weld the column (8), there is a lot of disadvantages such as excessive eccentric load on the column.

4A and 4B, the pillar fitting tube 12 is welded to the steel reinforcing rod 7 without welding the pillar 8 directly to the steel reinforcing rod 7, and then the pillar 8 is moved to the site. 12) can also be fitted. Thereafter, there is also a method of welding the nut to the pillar 8 or the pillar fitting tube 12 before the final finishing or welding by welding, and then tightening the bolt 13 at the site. It is a widely used technique when assembling a tent frame, but the installation of the pedestal tank is low in strength, 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 pillar fitting tube 12 is larger than the pillar 8 as shown in FIG. 4A, the nut should be welded to the pillar fitting tube 12, and the pillar fitting tube 12 is smaller than the diameter of the pillar 8 as shown in FIG. 4B. The nut must be welded to the column 8 and the bolt 13 must be tightened. If the height of the column 8 is increased, it is inevitable to reinforce the horizontal reinforcement (9). In this case, it is convenient to manage the discharge valve 6 by providing an intermediate scaffold with a flat steel plate on the horizontal reinforcement material 9 of the lower part about the height of the lower plate 3.

If there is a lower manhole 5a as shown in Fig. 3b, the lower manhole 5a can also be managed. If the lower manhole (6) has a convenient tank cleaning, but the price is expensive. Opening and closing of the lower manhole 5a is also a problem unless you are an expert because you have to loosen and tighten a number of bolts.

Piping connection of the tank of the present invention can be made in the upper and lower parts of the body 1 as in a general cylindrical water tank, or in the dish-shaped lower plate 3 like a spherical water tank. However, the drain valve (Drain) (6) in any case must be installed in the center of the bottom plate (3) to be completely drained and effective for the discharge of sediment (self-cleaning).

When piping is connected to the lower plate (3), attention is to be paid to the strength of the lower plate (3). Because the greatest stress is generated in the lower plate, if the hole is drilled roughly, the strength decreases, and the defect is concerned. Therefore, flange connection is safer than socket connection.
