Description

{STS water tank equipped with ferroconcrete band with reinforced concrete band}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water tank, and more particularly, to an STS water tank in which a reinforced concrete band is formed at a lower end of an outer peripheral surface in a single stage.

The water tank is a fluid storage tank used for various purposes. Since the fluid has a considerable weight, as well as a solid body, and there is no uniform shape, the water tank in which the fluid is stored must be structurally rigid to prevent the force to spread the fluid to a low point. Therefore, in general, the water tank is provided with concrete on the outside of a stainless steel housing in which the fluid is directly stored. Here, the stainless steel is a material that prevents the fluid from deteriorating even if the fluid is stored for a long time, and the airtightness is maintained so as to prevent leakage of the fluid. And concrete reinforces the structural stiffness of the enclosure which can be deformed by tensile force, so as to maintain the shape of the enclosure.

In a conventional water tank, the enclosure is also referred to as an inner liner, and both the outer concrete and the enclosure are generally formed in the same shape. However, as the fluid pressure inside the housing increases toward the bottom of the fluid, the pressure to expand outward due to the load of the upper fluid increases. Therefore, if the upper and lower thicknesses of the outer concrete and the amount of the used steel reinforcement are the same, conventionally, the amount of steel and concrete necessary for maintaining the required rigidity is required at the upper portion of the concrete. Reinforced concrete and concrete can be used.

In addition, since the water pressure inside the water tank is the largest at the bottom, in the case of the STS water tank composed of the iron panel only, leakage or breakage occurs in the water tank itself due to internal water pressure or cracks between the bottom wall of the side wall and the bottom plate There is a high degree of concern.

As a result of this, it is considered that the problem of the inefficiency of the material input efficiency due to the use of a larger amount of reinforcing steel and concrete than the actual required amount of reinforcing steel and concrete or the application of the thick STS plate and the structural reinforcing effect Is small.

However, in the prior art, there is no description of a water tank having such a structure that this problem can be solved.

On the other hand, in the case of a water tank used in an advanced water treatment system, the residence time of water can be prolonged so that chlorine can be dissolved evenly in the water tank, and also chlorine A technique to prevent the phenomenon that the drug of the drug is unevenly dissolved is needed.

For reference, the advanced water treatment system is composed of a rubber boat with an air supply and a floodgate that floods the river and draws water from soil, sand and other foreign matter, and coagulant, powdered activated carbon and chlorine A sedimentation paper for sedimenting various impurities and swirling only clean clear water, a sand filter for filtering fine impurities through a sand layer, a water supply device for supplying water supplied through an intermediate pressurizing pump, Is used for an ozone contact paper for highly purified water treatment, a bioactive activated carbon adsorption paper, a water feed pump, and a purified water pipe.

Conventional rectangular concrete water tanks used in cleansing papers are designed to water chlorine-added water from the absorbent paper for the purpose of sterilizing various bacteria contained in the filtered water, (Approximately 30 minutes), and then supplied to the home via a water feed pump.

The conventional water tank is a hexahedron having an empty internal space buried in the basement. The conventional water tank has a water supply pipe having a chlorine charging device installed at an upper portion thereof and a drain pipe penetrating through a water supply pump at a lower portion thereof. .

These rectangular water tanks are capable of storing tens to hundreds of tons of water at the same time, and the chlorine input by the chlorinator is diluted and stored in water.

The above-described conventional water tank has the following problems.

In conventional water tanks, chlorine is designed to be dispersed throughout the water within 30 minutes, so that chlorine can be discharged directly to the outlet before being diluted sufficiently in the water, or tap water having a sufficient sterilization time can be supplied to the home.

For example, when tap water having an excessive residual chlorine concentration is supplied to the home, when the concentration of residual chlorine in the tap water is high, it is not suitable for drinking water because the odor is smelled, and the possibility of generation of a trihalomethane (THM) Or water that contains various invisible bacteria may be supplied to the user.

These accidents can be prevented if the chlorine and water flow sufficiently and the residual chlorine concentration is maintained at the optimum level. To do this, it is best to keep chlorine and water in contact for a sufficient amount of time while maintaining a smooth flow of water.

Of course, in conventional water tanks, zigzag type flow-through walls are protruded on the inner wall to interfere with the flow direction of the fluid to make the flow of the fluid longer, so that the chlorine and water can be contacted while flowing in the 'S' There is a case. In this case, the contact time between water and chlorine in the water tank can be relatively long.

Korean Registered Patent No. 10-0953668 (Registered on Apr. 12, 2010) discloses a junction type wall partitioning apparatus and a water treatment plant wall including the same. The flow-through walls are welded and welded between the partition wall members, and a considerable amount of time is required for the welding process while the welding material is used for the welding. Thus, there is a problem that welding is difficult.

In addition, in the prior art, a portion where water is stagnated is formed at the corners of the flow path where the flow-through wall is installed and the inner edge of the water tank, and stagnant water (dead water) is generated. There is a problem that the dilution performance of chlorine, ozone, sterilizing agent, liquid and solid disinfectant is poor because the flow of water is not smooth at such a stagnant part.

On the other hand, when the shape of the water tank is rectangular, it is preferable in view of the space utilization, but it is preferable that the shape of the water tank is made cylindrical in order to increase the maximum permissible tensile stress.

However, in the case where the water tank is formed into a cylindrical shape, there is no conventionally proposed technique for a structure in which an internal fluid flow path can be formed with the longest distance for an effective residence time for dissolving a drug, There is no description of a structure capable of preventing flow generation.

Patent Registration No. 10-0953668 (Registration date: Apr. 12, 2010)

The STS water tank is provided with a reinforcing material that prevents the water tank from being collapsed or shrunk due to the concrete pouring pressure in the process and can prevent the installation position from being deformed or dislodged even if an earthquake occurs.

To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, an STS water tank having a reinforced concrete band according to the present invention comprises a cylindrical sidewall, a bottom plate and an upper plate made of a stainless steel panel, Wherein the side wall is formed with a plurality of stages and the ends of the side walls are different in thickness from each other, a reinforcing concrete band integrally joined to an outer circumferential surface of a lower portion of the side wall of the housing part, And a swirling wall portion formed inside the space between the inlet and the outlet to form a labyrinth shape.

Here, the height of the reinforced concrete band is preferably the same as the height of the lower end among the plurality of steps constituting the side wall of the hermetic part.

Preferably, among the plurality of steps constituting the side wall of the hermetic container, the end disposed at the center among the remaining steps excluding the lowermost end has the largest thickness.

At this point, a corner guide wall for connecting the maze vertical wall and the divided vertical wall or the inner wall of the housing is formed at a point where one end of the maze vertical wall and the divided vertical wall or inner wall of the housing are coupled, A free end guide plate is provided at the free end which is extended from the end of the free end in an inclined manner to gradually decrease the width of the fluid traveling space.

The vertical plate is disposed between two labyrinth vertical walls opposed to each other with the fluid proceeding space therebetween. The vertical plate is inclined in the same direction as the free end guide plate and is arranged to face the free end guide plate, An inclined guide is provided to divide the fluid into space into two or more pieces.

Wherein the inclined guide is disposed between the free end guide plate and the maze vertical wall and is arranged in such a manner that two plates inclined in the same direction as the free end guide plate are overlapped at regular intervals, A first inclined guide disposed close to the guide plate and having a predetermined angle with the opposing labyrinth vertical wall, and a second inclined guide disposed between the first inclined guide and the opposing labyrinth vertical wall and disposed at an angle smaller than the predetermined angle And a second inclined guide.

In this case, the inclined guide is preferably formed as a curved surface whose curved surface faces the free end guide plate.

The specific structure or functional description presented in the embodiment of the present invention is merely illustrative for the purpose of illustrating an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention can be implemented in various forms. And should not be construed as limited to the embodiments described herein, but should be understood to include all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The plate of the STS water tank in which the reinforced concrete single-stage band according to the present invention is installed is composed of a hollow portion 10 made of STS and having a plurality of stages in the height direction, Reinforced concrete bands 20 of one layer or a plurality of layers and a trough wall portion 30 provided inside the housing portion 10.

The housing part 10 corresponds to a tank which is stored while being in direct contact with the fluid as indicated by a dotted line in FIG. Like a liner inside a conventional concrete water tank, has a hermetic structure so as not to leak the stored fluid and has a certain rigidity to prevent the internal fluid from expanding due to the rigidity of the plate material itself.

The housing portion 10 is made up of a cylindrical wall portion 12 and a top plate 11 for sealing the upper space defined by the side wall 12 and a bottom plate 15 below the side wall 12. 2 and 3, the side walls 12 forming side surfaces of the hermetic unit 10 are formed by laminating a plurality of cylindrical ends having the same or different thicknesses in the height direction. In this case, the interaction between the thickness of each end 12-1, 2, 3, 4 of the side wall 12 and the reinforcing concrete band 20 will be described below.

Among conventional water tanks, a water tank having a reinforced concrete outer wall without a reinforced concrete outer wall and being constructed so as to withstand the internal water pressure only has a thick plate material in order to resist internal water pressure only by an iron plate, As shown by the left curve and the arrow length indicating the magnitude of the hydraulic pressure in FIG. 3, the greatest internal water pressure acts between the bottom of the side wall and the bottom plate forming the housing, and a crack due to the fine notch between the side wall and the bottom plate And there is a possibility that massive water and water tank destruction may occur.

To this end, in the present invention, firstly, instead of the conventional reinforcing concrete outer wall, a reinforcing concrete band is provided which is connected only to the lower outer circumferential surface of the casing part made of the iron plate. This is because the hydraulic pressure of the fluid stored in the housing portion increases sharply from the upper portion to the lower portion as shown in the left side of FIG. 3, so that the reinforcing concrete band should be installed on the lower outer circumferential surface of the housing portion where the maximum load is concentrated.

Secondly, unlike the conventional hermetically sealed parts, in the present invention, the hermetically sealed parts are formed by forming a plurality of layers having the same or different thickness from each other. As shown in FIG. 3, the end 12-2 immediately above the lowermost end 12-1 is connected to the lower end 12-1 (FIG. 3) due to the supporting force reinforcement of the reinforcing concrete band on the outer peripheral surface of the lowermost end 12-1 Is strongly supported from the water pressure, even in the case of the immediately adjacent step 12-2, it is not inflated by water pressure but is firmly supported against water pressure. However, since the third stage 12-3 from the bottom is distant from the reinforcing concrete band, deformation larger than the lower stage 12-2, which is subjected to a large hydraulic pressure, may be generated. Therefore, the thickness of the third stage 12-3 from the bottom needs to be the largest. However, the step (12-4) located at the uppermost position may be smaller in thickness than the lower end (12-3) because it receives the least amount of hydraulic pressure and is less likely to be deformed by being connected to the upper plate.

According to the present invention, in the present invention, the reinforcing concrete band is provided only on the outer peripheral surface of the lowermost end instead of the outer wall on the entire outer peripheral surface of the housing part, Since the reinforced concrete outer wall is not provided at the upper part, the thickness of the side wall of the housing part is made somewhat thicker than that of the ordinary side wall, and the lower end of the second end 12-2 and the upper end of the side wall 12 -4 is made to be the reference point and the thickness of the end 12-3 at the most center among the side walls 12-3 is maximized so that the sidewalls between them can be prevented from being deformed like bow, So as to have a uniform bearing capacity against the internal water pressure.

As a result of the construction of the side walls and the reinforced concrete bands as described above, in the present invention, the reinforced concrete outer wall is not installed on the entire outer surface of the side wall of the hull, In addition to having a resilient supporting force, the sidewalls, which are most likely to be damaged due to the greatest hydraulic pressure among the side walls of the hull, are reinforced most intensively and intensively to prevent breakage of the hull.

Therefore, even when a plate material having a smaller thickness is used, the deformation amount of the plate material is reduced and the yield safety rate is further increased compared to a conventional water tank that can withstand the internal water pressure only by the housing portion.

These effects are shown in the table of FIG. 4 showing the water tank capacity and the required material measured after the actual production.

In the table of FIG. 4, data for a conventional STS water tank is shown at the top, and data for a water tank according to the present invention is shown at the bottom.

As shown in the table of FIG. 4, the STS water tank according to the present invention, to which a reinforced concrete band is applied, has a maximum deformation amount as compared with an STS water tank that can withstand internal water pressure only by a hermetically- The yield safety factor is 2.22, which is higher than the conventional 1.47, and the thickness of the plate material used is 2.0 mm, which is thinner than the conventional 3.0 mm, except for the second stage 12-3, Mass is reduced by 19%. However, there is an increase in mass as much as the amount of reinforcing steel and concrete required to produce a reinforced concrete band.

Therefore, it can be seen that the deformation amount is reduced and the yield safety ratio is increased by applying the reinforced concrete band in the present invention.

Meanwhile, the STS water tank 100 in which the first-stage band of reinforced concrete according to the present invention is installed may be introduced into the hollow portion 10 when used in the settlement paper of the advanced water treatment system as described in the Background of the Invention Chemicals such as chlorine should be uniformly mixed into the water before the water is drained. Therefore, the interior of the housing portion 10 should be formed in such a structure that the flow can be maintained for a time in which water can be sufficiently mixed with chlorine.

In order to maintain the fluid flow for a certain period of time, a maze-like flow wall portion 30 is installed inside the housing portion 10 in the present invention. The labyrinthine-shaped wall portion 30 according to the present invention can be largely divided into two embodiments, one of which is shown in Figs. 5 to 10B and the other of which is shown in Figs. 11a to 11c .

The cryoprotective wall portion 30 of the first embodiment of the cryopipe wall portion 30 is divided into a divided vertical wall 31 for separating both sides of the interior of the crotch portion 10 with reference to Figure 5, And a labyrinth vertical wall 32 provided so as to be formed in a staggered maze.

As shown in Fig. 5, the labyrinth vertical wall 32 is largely composed of three types A, B, In Fig. 5, D denotes the divided vertical wall 31. However, the shape and quantity of the maze vertical wall 32 are not limited to those shown in Fig. 5, but may be more or less than those shown in Fig. 5 depending on the capacity of the hermetic portion 10, and the specific shape may vary.

As described in the background section, in a rectangular water tank, a flow-inducing wall is attached at right angles to the long-side sidewall of four inner walls, while the flow-inducing walls attached to the long-sidewall opposite to each other are staggered to flow zigzag The fluid retention time within the water tank is maintained for a certain period of time, so that the sterilizing agent and water can be sufficiently mixed.

However, in the case of the hollow portion 10 formed as a circular shape as in the present invention, when a flow-through wall is provided in the form of a rectangular water tank, the central flow path passing through the inner center becomes too long, and as the flow direction approaches the water inlet or outlet, So that the entire length of the channel can not be ensured so that the time for the sterilizing agent and water to be sufficiently mixed can not be secured.

Therefore, in the present invention, as shown in FIG. 5, the inlet 13 and the outlet 14, through which the water is introduced into the container portion 10, are closely adjacent to each other so that the sterilizing agent and water can be sufficiently mixed in the container portion 10 And a divided vertical wall 31 that divides the interior of the housing portion 10 in the horizontal direction is provided on the inner wall between the inlet 13 and the outlet 14 so that the water flowing into the inlet 13 on the right side is divided, The longest flow path can be formed from one space divided into the upright wall 31 to the opposite space and finally discharged to the left outlet 14, thereby ensuring a sufficient mixing time.

In this case, the divided vertical wall 31 protrudes from the inner wall between the inlet 13 and the outlet 14 and forms a divided vertical wall 31 from the inner wall of the opposed inner wall, Is formed at a distance from the inner wall on the opposite side of the protruding portion by a predetermined distance. Therefore, the water introduced into the right space of the divided vertical wall 31 passes over the upper side space of the divided vertical wall 31, that is, the space formed by the separated length, Respectively.

9, the maze vertical wall 32 is installed in each of the spaces divided by the divided vertical wall 31, and is provided at a right angle to the divided vertical wall 31, Are installed so as to flow in a zigzag manner. In FIG. 5, A, B, and C represent each maze vertical wall 32. At this time, the lengths of the divided vertical walls 31 are all three kinds of lengths in the embodiment of FIG. That is, a pair located at a point symmetrically horizontally on each of the labyrinth vertical walls 32 provided on both sides of the divided vertical wall 31 are not mirror-symmetrical but are rotated 180 degrees, A pair of labyrinth vertical walls 32 having a length equal to or greater than the length of the labyrinth vertical wall 32 can be provided. In other words, there are only three types of maze vertical walls 32 according to the length of the maze vertical wall 32 shown in Fig. 9.

The labyrinth vertical wall 32 is formed as shown in the perspective view of FIG. 6, specifically, one plate member 321 shown in FIG. 7 is connected to each other in the form of FIG. At this time, one end or both ends of the maze vertical wall 32 is formed as a recessed end portion 3212 as shown in FIG. 7 or 8, and when the two plate materials 321 are connected, the recessed end portions 3212 are connected to each other A diamond shaped support bar 322 is inserted in the horizontal cross section and the fastening member 3214 is passed through the extension fastening plate 3213 on both sides of the recessed end portion 3212 Two or more plate members 321 are connected in parallel to form one labyrinth vertical wall 32.

The water introduced into the interior of the housing part 10 through the inlet port is formed at a corner (hereinafter referred to as a corner) where the maze vertical wall 32 and the inner surface of the side wall 12 of the accommodation part 10 meet A stagnating flow (D) can be formed as a partial swirl is formed. This stagnant flow (D) is represented in Fig. 10A.

In order to prevent the stagnant flow D, in the present invention, a free end guide plate 324 is attached to the free end of the maze vertical wall 32 for each maze vertical wall 32 to prevent the formation of the stagnant flow D .

The free end guide plate 324 is attached in such a manner as to extend obliquely from both free ends of the labyrinth vertical wall 32, as shown in FIG. 5, wherein the oblique direction is the direction of the fluid flowing between the labyrinth vertical walls 32 And the width of the fluid flow is gradually narrowed toward the advancing direction of the fluid.

As the width of the fluid flowing through the free end guide plate 324 becomes smaller, the flow velocity of the fluid increases, so that a part of the fluid pressure is changed into kinetic energy, and the stagnant flow that can be formed at the corner due to the kinetic energy of the increased fluid (D) is disturbed, formation of stagnant flow (D) can be prevented.

Further, in order to more precisely prevent the formation of the stagnant flow D, the corner guide wall 323 may be provided for each corner as shown in FIG. The corner guide wall 323 is curved so that the flow of fluid at the corner is rapidly disturbed and is not disturbed so that a part of the fluid is prevented from being formed in the stagnant flow D in the course of the fluid- .

9 and 10B, in the present invention, an inclined guide 325 is additionally provided so that the stagnant flow D can be thoroughly prevented.

The inclination guide 325 is installed between two labyrinth vertical walls 32 arranged parallel to each other as shown in Fig. 10B, which is an enlarged view of the area indicated by F in Figs. And is disposed between the maze vertical wall 32 and the free end guide plate 324 so as to have an angle similar to that of the free end guide plate 324. That is, the inclined guide 325 is disposed in parallel with the free end guide plate 324 as a whole.

9 and 10B, the inclination guide 325 is provided between the first inclination guide 3251 close to the free end guide plate 324 and the first inclination guide 3251 between the first inclination guide 3251 and the maze vertical wall 32 And a second inclined guide 3252 to be disposed.

In the case where the inclination guide 325 is not provided, as shown in FIG. 10A, the water impinging on the free end guide plate 324 is suddenly bent in a direction, and a vortex occurs in the area indicated by D, ).

In this case, when the first and second inclination guides 3251 and 3252 as shown in FIG. 10B are installed, first, the water impinging on the free end guide plate 324 is inclined at an angle between the direction of the reverse direction and the direction toward the corner Even if the first inclined guide 3251 is bent, the curved surface of the first inclined guide 3251 collides with the curved surface of the first inclined guide 3251, Second, the water entering between the first and second inclination guides 3251 and 3252 is gradually reduced in width between the first and second inclination guides 3251 and 3252, The possibility that the stagnant flow D due to the swirling of the water passing through the guides 3251 and 3252 at the corner can be more thoroughly prevented. Thirdly, the water flowing between the second inclination guide 3252 and the labyrinth vertical wall 32 is also generated at the corner as the space between the second inclination guide 3252 and the labyrinth vertical wall 32 becomes narrower, Thereby preventing occurrence of stagnation flow (D) due to possible swirling.

In particular, the first and second inclination guides 3251 and 3252 can be accelerated in one direction to prevent water from forming a stagnant flow D in a predicted area where stagnant flow D can occur, The formation of the stagnant flow D can be thoroughly prevented by forming the fluid passage with the stagnating flow D formed thereon.

On the other hand, Fig. 11A shows another embodiment of the maze vertical wall 32. Fig.

Structural rigidity is required because the labyrinth vertical wall 32 receives a large force due to the weight and speed of the water passing between the labyrinth vertical walls 32. However, if the thickness of the maze vertical wall 32 is increased for the structural rigidity, the manufacturing cost of the maze vertical wall 32 increases and the space inside the hollow portion 10 becomes narrow.

In this case, if the labyrinth vertical wall 32 is formed in the form of a waveform in which the curved surface and the convex surface appear alternately as shown in FIG. 11A, the curved surface has sufficient stiffness And the convex surface has a sufficient rigidity due to the dispersion effect of the force due to the arch structure because the velocity of the fluid passing through the convex surface increases and the pressure decreases. Therefore, when the maze vertical wall 32 having the waveform shape as shown in FIG. 11A is manufactured as compared with the flat maze vertical wall 32 as shown in FIG. 9, the maze vertical wall 32 has more excellent rigidity.

In this case, in order for the labyrinth vertical wall 32 to be easily manufactured in the form of a waveform, if there is an inflection point in one plate member 321 constituting the labyrinth vertical wall 32, If the curved surface is formed only in one direction and the inflection point is formed between the plate member 321 and the plate member 321, the plate member 321 can be easily formed. That is, it is preferable that the center of curvature in the sectional shape of one plate member 321 is always positioned in only one direction.

Also, in the embodiment in which the maze vertical wall 32 is formed in the shape of a waveform, the corner guide wall 323 may be provided for each corner as shown in FIG. 11C.

11A and 11C, the maze vertical wall 32 is always inclined in the direction opposite to the fluid flow as shown in FIGS. 11A and 11C. As the fluid approaches the corner, the interval is narrowed and the velocity increases. It is possible to effectively prevent the formation of the stagnant flow D from occurring at the corners due to the kinetic energy.

As shown in FIG. 12, the STS water tank having the reinforced concrete band according to the present invention is characterized in that the concrete pushed into the mold M in the process of manufacturing the mold M for the pyramidal outer wall 20 expands The shrinkage preventing member 50 may be installed so that the hermetic unit 10 is not contracted or dented by the pressure.

The shrinkage preventing member 50 includes a plurality of connecting arms 51 which are embedded in the outer wall 20 and one end is protruded outside the outer wall 20 and the other end is fixedly attached to the outer circumferential surface of the housing portion 10, A coupling plate 52 integrally coupled to one end of the coupling member 51 and projecting together to the outside of the outer wall 20 and a coupling plate 52 integrally coupled to the other ends of the coupling arms 51 to be attached to the outer peripheral surface of the coupling member 10, And a fastening pin 54 for fastening and fastening the plate 53 and fastening plates 52 provided at one ends of the plurality of connecting arms 51, respectively.

12, when the three connection arms 51 are bundled together by the fastening pins 54, the lengths of the upper connection arms 51 and the lower connection arms 51 are made longer than the center connection arms 51 . This is because the upper and lower connection arms 51 are bent and the central connection arm 51 is not bent so that the other ends of the upper and lower connection arms 51 and the center connection arms 51 are spaced apart from each other by a predetermined distance. Because.

On the other hand, as shown in FIG. 13A, the bottom plate 15 of the hermetic unit 10 can be fixed firmly to the base ground G so that the seismic member 40 can be installed to withstand the earthquake.

Here, the seismic member 40 may be an anchor bolt 41 as shown in Fig. 13 (b) or may be any known member having an action similar to that of the anchor bolt 41.

In this case, the installation of the seismic member 40 needs to maximize the effect of installing the minimum amount of water as much as possible. To this end, in the present invention, the vibration-proof member 40 is installed at every 60 degrees radially symmetrically from the center of the bottom plate 15 of the housing portion 10. 13A, the seismic member 40 is not only radially symmetrical but also is symmetrical with respect to the center of the bottom plate 15, and the adjacent seismic member 40 is symmetric with respect to the center of the bottom plate 15, The equilateral triangle formed by connecting the center of the bottom plate 15 and the bottom plate 15 is a regular triangle, and an equilateral triangle formed symmetrically on the opposite side with respect to the center of the bottom plate 15 is formed, Stable dispersion and support can be achieved.

In the present invention, the vibration proof member 40 is composed of a rectangular base plate 42 through which the anchor bolt 41 and the anchor bolt 41 penetrate. Two anchor bolts 41 are provided in the longitudinal direction of the base plate 42. This is because when only one anchor bolt 41 is installed on the base plate 42, the water tank is moved in the direction of rotation with respect to any one of the anchor bolts 41 and the base plate 42 in a vibration generating state such as an earthquake, It can be separated from the ground G. The longitudinal direction of the base plate 42 is arranged parallel to the tangent line of the concentric circle with respect to the center of the bottom plate, thereby effectively preventing the inclined portion 10 from being separated from the foundation foundation G due to the external vibration. Further, the base plate 42 is installed radially with respect to the center of the bottom plate 15, so that the STS water tank according to the present invention is prevented from being eccentrically biased to one side under vibration occurrence.
