In general, in most residential and commercial buildings such as office buildings, apartments and public buildings, a water tank for supplying water is installed on a roof or underground, and a water tank is installed in a factory or the like for supplying industrial water.

Such a water tank is made of various materials, for example, Stainless steel (Stainless), Sheet Molding Compound (SMC), Fiber Reinforced Plastic (FRP), Concrete (Concrete), and the like.

The technology related to the water tank comprises a water tank which takes metal such as stainless steel and the like as a main material, the water tank is mainly small, and a large water tank is mainly of a concrete structure.

Among the technologies relating to such water tanks, patent document 1 relates to a water tank mainly made of metal, and patent documents 2 to 4 relate to a water tank having a concrete structure.

For such an existing assembled water tank or concrete water tank, various techniques are used to prevent leakage of water stored inside the water tank and corrosion of the inner wall.

For example, patent documents 5 to 6 relate to a technique for water-proofing and corrosion-proofing of such a water tank or sink.

Patent document 5 relates to a waterproof structure of a concrete tank using a polyethylene plate, as a water storage tank having a ship-body shape and supplying a certain amount of water to a building having a large usage amount of domestic water by storing the water, including: the drain holes of the concrete water tank are respectively communicated with the edges and corners equal to the bottom of the water tank; a fixing part for finishing the rough surface formed on the inner wall surface of the concrete water tank and fixing the composite plate; and a pipe distribution part at the lower end of the concrete water tank, the ground water isolation plate being fixed to the sleeve and the end of the sleeve being combined with the flange.

Patent document 6 relates to a waterproof structure of a concrete water tank, including: a waterproof sheet in which a metal plate and a polyethylene resin sheet are joined together with an adhesive, a side end portion of the polyethylene resin sheet is cut in a longitudinal direction to form an accommodation space, and an overlapping surface is formed on the metal plate at a lower portion of the accommodation space; a plurality of screw type ground anchors for overlapping the overlapping surface of the waterproof board and the overlapping surface of the adjacent waterproof board, and fixing the overlapping surfaces of the adjacent waterproof board and the waterproof board on the surfaces of the four wall surfaces and the bottom surface of the concrete water tank at a certain interval through the accommodating space opened to the upper part; and a sealing member for melting the polyethylene resin in the accommodating space of the adjacent waterproof board to fill the screw-type anchor, and welding the waterproof board and the polyethylene resin plate in the accommodating space of the adjacent waterproof board to seal them.

Such a conventional waterproof structure is generally formed by attaching waterproof sheets to the inner wall of a concrete tank, and the waterproof sheets are attached by applying an adhesive or the like to prevent water leakage between the waterproof sheets.

In addition, the inside of the water tank has a condition that bacteria are easily propagated due to humidity and darkness, which causes a problem that drinking water is polluted by bacteria such as coliform bacteria.

In addition, the existing water tank is directly fixed on a building or the ground, and when an earthquake occurs, the vibration can be directly transmitted to the water tank, so that the problem of crack or damage of the water tank occurs.

Therefore, a water tank having a shock-proof device is being developed, and patent document 7 is a related art developed and patented by the present applicant.

Detailed Description

While the invention is susceptible to various modifications and alternative embodiments, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. However, the present invention is not limited to the specific embodiments. It is to be understood that the invention includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

In the description of the drawings, like reference numerals are used for like constituent elements. In the description of the present invention, it is determined that the detailed description of the related known art will obscure the gist of the present invention, and the detailed description thereof will be omitted.

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

The invention carries out waterproof treatment on the inner wall of the water tank, and can prevent the mutually connected parts of a plurality of composite plates from leaking water.

Such a water tank of the present invention has a waterproof structure of a water tank in which a plurality of composite plates are provided on the inner wall of the water tank 100, and may have different arrangement structures according to the structure of the composite plate 10.

First, the composite sheet 10 shown in fig. 2 to 5 is a composite sheet 10 made of a PE nonwoven fabric 11 including an antibacterial agent 12, and fig. 7 to 9 are composed of a synthetic resin 13 laminated inside a tank and a stainless steel sheet 14 laminated on a surface facing a wall of the tank.

Both of the two composite plates are thus attached to the inner wall of the water tank using the adhesive 20 applied to the inner wall of the water tank 100, and the anchor 40 is provided at the end of the attached composite plate 10 to prevent the end of the composite plate from being separated from the wall.

And, a plurality of non-shaped grooves 100g are formed in the inner wall of the water tank, and the adhesive is made to penetrate into the non-shaped grooves 100g, so that the adhesive having penetrated into the non-shaped grooves functions as an anchor, so that the composite panel having been adhered to the outside is not separated from the wall.

Of course, the primer 30 may also be applied to the inner wall of the water tank before the adhesive 20 is applied.

The primer 30 prevents corrosion of the inner wall of the water tank 100 or protects the water tank from physical impact, and also allows smooth coating of the adhesive 20 thereafter, and serves as an adhesive for filling fine pores formed in the inner wall of the water tank 100 to reinforce the adhesive strength of the adhesive 20.

The primer may be any type of 1-liquid dispersion polyurethane that is harmless to the human body, cures at room temperature, does not generate bubbles when exposed to water, and does not swell.

The adhesive 20 is actually a means for adhering the composite plate 10 to the inner wall of the water tank 100 and thus is not harmful to the human body.

The non-fixed groove 100g is enlarged as shown in fig. 6, and the inner space is formed widely, so that the primer that has penetrated into the inner part does not leak, and the forming method is as follows: in the process of forming the water tank with concrete, after a mold is formed with a plate having a plurality of foam irregularly provided on an inner wall thereof, concrete is injected into the interior of the mold to fill the concrete with a portion other than the foam, and when the mold is separated, the portion provided with the foam forms an irregular groove 100 g.

When the primer is applied to the inner wall of the water tank in which the non-fixed groove 100g is formed, the non-fixed groove 100g is filled with the primer and the adhesive to be fixed.

As described above, two types of composite sheets 10 can be used, one type of composite sheet 10 is produced by impregnating the PE nonwoven fabric 11 with the antibacterial agent 12, and as shown in fig. 5, the PE nonwoven fabric 11 to which polyethylene fibers are attached in parallel or non-oriented arrangement is impregnated with the antibacterial agent 12.

The composite sheet 10 is a composite sheet including an antibacterial agent, and various composite sheets and antibacterial agents can be used, but it is preferable to use a material having excellent durability and water resistance.

For example, the inorganic antibacterial agent is a powder dried by wet pulverization and surface wetting (wetting) treatment, and includes 50 to 95 wt% of silicate mineral, 1 to 40 wt% of clay mineral and 0.1 to 10 wt% of metal ion.

The antibacterial agent 12 is mixed with the PE melt and then injection-molded to form PE fibers, and after the PE antibacterial fibers are produced in parallel or non-directional arrangement, the composite panel 10 is formed by spreading a binder and bending.

As shown in fig. 2 to 4, the composite sheet 10 thus constructed has inner adhesive portions 10i and outer adhesive portions 10o, which are overlapped with each other at opposite ends, wherein the inner adhesive portion 10i at one end of one composite sheet 10 is closely fixed to a wall by an adhesive and a fixing anchor, and the inner adhesive portions are overlapped and adhered so as to be covered with the outer adhesive portion 10o at one end of the other composite sheet 10, and the opposite surfaces of the inner adhesive portion 10i and the outer adhesive portion 10o are heat-welded, and the end of the outer adhesive portion 10o is further formed with a welded portion 10w by PE welding, thereby enhancing the coupling force with the inner wall of the tank.

If the water pressure of the water stored in the tank is high, the end of the outer bonding portion 10o of the composite panel is penetrated even by a small gap, and the water penetrated into the small gap expands the gap, so that the other portion is also separated from the inner bonding portion 10 i.

Therefore, the end of the external adhesive portion 10o is strongly adhered to the internal adhesive portion 10i by forming the welding portion 10w, thereby preventing the separation of the external adhesive portion.

As shown in fig. 2 to 4, the upper end of the lower composite plate 10 at the end of the composite plate 10 overlapping each other is stuck between the lower end of the upper composite plate 10 and the wall.

As described above, the lower end of the composite plate 10 disposed at the upper side covers the upper end of the composite plate 10 disposed at the lower side, so that the ends of the composite plate 10 are prevented from being exposed to the pressure of water filled in the water tank, thereby preventing the ends of the composite plate 10 from being separated.

Further, it is preferable that the present invention is capable of confirming whether or not the welding of the welding portion 10w is perfect, and for this purpose, a spark test plate 50 is provided on an inner wall of the water tank facing the welding portion 10w, thereby performing a spark test for confirming whether or not the PE welding is normal.

When the welding state of the welded portion 10w is confirmed by the spark tester, the spark test plate 50 senses whether a gap is generated in the welded portion 10w according to the electric generation spark output from the spark tester.

That is, if no gap is formed in the welded portion, the electric current generated by the spark tester is not induced by the spark test plate 50 and no spark is generated, but if a gap is formed, the gap generates an electric current to interact with the spark test plate 50 and a spark is generated.

As shown in fig. 2 and 3, a groove is formed in the inner wall of the water tank 100, and the spark test plate 50 is provided in the groove, thereby preventing the portion where the spark test plate 50 is provided from protruding.

As described, as another method of fixing the composite plate 10 to the inner wall of the water tank 100, the fixing anchor 40 is also used.

The water tank of the present invention has a composite plate 10 adhered to the inner wall of a flat water tank 100, and the inner side of the composite plate is always filled with water.

Accordingly, the composite sheet 10 adhered by the adhesive 20 is separated from the inner wall by moisture.

That is, the water tank is a space for storing water, water flows between the inner wall of the water tank and the composite plate 10 due to a change in air temperature or a difference in temperature between water and the water tank, and the composite plate at a portion adhered with the adhesive is separated from the inner wall of the water tank due to the flowing water, and the fixing anchor 40 is provided to prevent such a phenomenon.

As described above, the other composite plate 10 of the present invention is formed by laminating the synthetic resin 13 and the stainless steel plate 14, and the composite plate thus formed can be fixed to the inner wall of the water tank by the adhesive 20, the primer 30, and the non-setting groove 100g as described above, but is more firmly fixed by providing the cover 60 in addition to such a fixing structure.

That is, as shown in fig. 7 to 9, the fixing structure of the composite plate 10, which is formed by laminating the synthetic resin 13 and the stainless steel plate 14, is further provided with a cover 60, which surrounds the end portion of the composite plate including the anchor 40 and whose edge is welded to the composite plate.

As shown in fig. 7 to 9, the composite plates are not overlapped with each other but are disposed to be end-to-end.

Also, preferably, the space between the cap 60 and the composite plate 10 is filled with a filler material 61.

As shown in fig. 7 to 9, the cover 60 protrudes toward the inside of the tank, and thus a space is created between the protruding cover and the composite plate, and if the space exists, water permeates into the space to deteriorate waterproof performance.

Thus, the space between the cap 60 and the composite plate 10 is filled with a filler material 61.

A l-shaped bonding wing 14w is formed at the end portion of the stainless steel plate 14 connected to each other, a bonding cap 62 is provided to connect and fix the l-shaped bonding wing 14w formed on the adjacent composite board, a step portion 14d bent toward the composite board main body side is formed at the end portion of the l-shaped bonding wing 14w, and preferably, the step portion is inserted and bonded into the step portion insertion groove by bending the end portion of the bonding cap 62 to surround the step portion and form a step portion insertion groove 62 c.

Further, a reinforcing wire 63 is provided inside the joining cap 62, and the reinforcing wire is fixed by being pulled to the l-shaped joining wings of two adjacent composite plates.

The reinforcing wire 70 functions as a clip for closely fixing the two L-shaped bonding wings 14w to each other, and is provided in a ring shape so as to surround the two L-shaped bonding wings 14w and have both ends connected to each other.

The construction method of the composite plate of the water tank of the present invention constructed as described above is as follows.

In general, a method for constructing a water tank waterproofing structure using a composite plate is a method for installing a composite plate for waterproofing inside a water tank 100 made of concrete, including: a field actual measurement step, wherein the structure is grasped by actually measuring the interior of the water tank needing water proofing, and whether a protruding part or a crack part exists is determined; a surface operation step, namely removing the protruding part in the water tank or filling the crack part, removing foreign matters on the surface and grinding to finish the inner wall of the water tank; a primer operation step, namely uniformly coating a primer on the inner wall of the water tank; a step of uniformly coating an adhesive on the inner wall of the water tank so as to be capable of adhering the composite plate; and a composite plate attaching step of attaching the composite plate to the adhesive surface.

This process is similar to the general wall construction process for composite panels.

The present invention is characterized by adopting a construction method of connecting the connection portions between the composite plates 10 disposed at the inner wall of the water tank 100 without water leakage.

As shown in a partially enlarged view in fig. 5, the composite sheet 10 is produced by impregnating the PE nonwoven fabric 11 to which polyethylene fibers are bonded in parallel or non-directional arrangement with the antibacterial agent 12, and as shown in fig. 7 to 9, the composite sheet can be formed by laminating the synthetic resin 13 and the stainless steel sheet 14.

The composite plate attaching step, which is a characteristic of the present invention, may be different depending on the structure of the composite plate, and first, as shown in fig. 2 to 5, in the composite plate 10 made of the PE nonwoven fabric 11 including the antibacterial agent 12, the composite plate 10 is attached from one side end portion of the inner wall of the tank 100, and the surface of the inner adhesive portion 10i attached to one end of the previously installed composite plate 10 and the outer adhesive portion 10o attached to one side end portion of the adjacent composite plate are overlapped with each other.

In particular, as shown in fig. 2 to 4, in the case of the overlapping end portions of the composite plates 10, the upper end portion of the lower composite plate 10 is bonded between the lower end portion of the upper composite plate 10 and the wall.

In contrast to the present invention, when the upper end portion of the lower composite plate 10 is adhered to the outside of the lower end portion of the upper composite plate 10, i.e., the inside of the tank, the water pressure of the water filled in the tank is applied to the upper end of the lower composite plate 10 protruding outward, and the upper end portion of the lower composite plate 10 is easily separated from the wall.

Therefore, in the present invention, as described above, the upper end portion of the lower composite plate 10 is bonded between the lower end portion of the upper composite plate 10 and the wall.

The end of the outer adhesive portion 10o is PE-welded to form a welded portion 50 so that water leakage between the two composite panels 10 does not occur, and a plurality of anchor anchors 40 are provided at the end of the inner adhesive portion 10i to prevent the end of the composite panel 10 from being separated from the wall.

In the method for waterproofing a water tank using a composite sheet as described above, the spark test sheet 50 is preferably provided on the surface of the inner wall of the water tank 100 facing the welded portion 10w before the composite sheet is attached, and the welded state of the welded portion is preferably checked by a spark tester after the composite sheet is attached.

The waterproof structure of the water tank constructed by the method, in order to enable the composite plate 10 to be more firmly adhered to the inner wall of the water tank, it is preferable that a plurality of non-molding grooves 100g be formed on the wall of the water tank.

As shown in fig. 4 and 6, an amorphous groove 100g is formed on the wall of the water tank, and as the groove is filled with a primer 30 coated on the wall and an adhesive 20 coated on the surface of the primer, the composite panel 10 adhered to the inner wall of the water tank with the adhesive is not separated from the wall of the water tank.

That is, if the flat composite plate 10 is attached to the flat wall with the adhesive and the primer, as long as a part of the middle of the composite plate is opened and separated from the wall, the other part is also separated from the wall.

Accordingly, as described, a plurality of non-shaped grooves 100g are formed on the wall, and when the primer and the adhesive penetrate into the non-shaped grooves 100g, these serve as an anchor to prevent the outer-adhered composite panel from being separated from the wall.

As shown in fig. 7 to 9, the composite plate 10 formed by laminating the synthetic resin 13 and the stainless steel plate 14 is attached such that one end of the composite plate 10 is in contact with one end of another composite plate, by attaching the composite plate 10 from one end of the inner wall of the tank 100.

A cover 60 may also be provided to cover the contact portion between the two composite plates so provided.

As shown in fig. 8 and 9, before the cover 60 is provided, the inside of the cover is filled with a filler 61 so that no space is formed between the cover and the composite plate.

After the plate is attached, a bonding cap setting step may be further performed to set a bonding cap on the l-shaped bonding wing 14w formed at the end of the composite plate.

The step of providing the cap is welding the edge of the cap to the composite panel after aligning the cap to the end of the composite panel including the tie-down anchor and the bonding cap.

After the bonding cap is provided, a reinforcing wire is further provided inside the bonding cap, and ends of the reinforcing wire are connected to each other so that the L-shaped bonding wings of the two composite sheets are closely attached to each other.

In addition, as shown in fig. 11 and 12, the water tank of the present invention is further provided with a plurality of shock-proof devices 70 at the lower portion of the water tank 10 so that an earthquake or other vibration is not transmitted to the water tank.

The shock-proof device 70, as shown in fig. 12, may be arranged at equal intervals, as shown in fig. 13 to 19, and may include: the sliding device 71 is arranged on the bottom surface of the water tank, and an arc-shaped groove 71a is formed on the bottom surface; a rotary ball 72 moving along an arc-shaped groove formed on the sliding plate to absorb horizontal vibration applied to the water tank; and an elastic ball support means 73 for elastically supporting the rotary ball to be rotatable, and absorbing vertical vibration applied to the water tank.

As shown in the drawing, the sliding plate 71 has a groove formed on a surface facing the rotary ball 72, and has an arc-shaped surface from the center to the edge so that the rotary ball can smoothly roll, and even if vibration is generated on a floor on which the water tank is installed, the vibration is not transmitted to the water tank.

That is, the rotary ball 72 horizontally moves along the arc-shaped groove 71a formed on the sliding plate 71 to absorb the horizontal and vertical vibrations, so that the water tank does not generate vibrations.

In order to prevent the water tank from vibrating up and down even when the rotary ball 72 moves up and down or horizontally, the elastic ball support means 73 is provided to absorb the vibration of the rotary ball 72.

The elastic ball support means 73 is used to absorb the vibration of the ground so that the vibration is not transmitted to the water tank, and various modifications may be made thereto, examples of which are shown in fig. 13 to 19.

The elastic ball support means 73 is configured to rotatably support the rotary ball 72, and an elastic support 74 is provided inside a housing 73h fixed to the bottom surface of the water tank.

The elastic support 74 may have various configurations, and fig. 13 shows an elastic pad provided between an arc-shaped groove 73g formed on the upper surface of the housing and the rotary ball.

The elastic support 74 in the form of an elastic pad configured as described above is a simple hemispherical pad as shown in the drawing, and may be made of rubber or synthetic resin having excellent elasticity. However, since the elastic pad of this type cannot effectively absorb the vibration of the ground, it is preferable to provide a structure having more excellent elasticity as shown in fig. 14 to 19.

That is, as shown in fig. 14, the elastic support 74 is preferably constituted by a compression spring provided inside the housing. The compression spring can absorb the vertical vibration of the ground to reduce the vertical vibration of the rotary ball 72.

As shown in fig. 15, another example of the vibration absorber 74 is formed by filling an elastic resin or rubber having excellent elasticity into the casing. In this configuration, although the elastic resin or rubber absorbs the vibration, a space in which the elastic resin or rubber can expand laterally needs to be formed in the housing 73h so as to expand laterally in accordance with the vertical contraction.

The other vibration absorber 74 is composed of an elastic material 74m filling the inside of the housing and a lifting body 74e provided on the upper part of the elastic material and transmitting the pressure applied by the rotary ball to the elastic material, as shown in fig. 16 to 19.

When the elastic absorber 74 configured as described above vibrates on the floor, the elastic absorber 74m absorbs the vibration, thereby absorbing the vertical vibration of the lifter 74e and reducing the vertical vibration of the rotary ball.

As shown in fig. 16 and 19, the elastic material 74m may be a spring, or as shown in fig. 17 and 18, may be an elastic rubber or resin.

An auxiliary elastic body 74s may be provided at the center of the upper end of the elevating body 74 e.

The auxiliary elastic body 74s serves to assist in absorbing the vibration that has been transmitted to the rotary ball, and may be composed of a spring or rubber or synthetic resin having excellent elasticity, as illustrated in fig. 15.

The lifting body 74e is a piston, and the elastic body 74m may be made of a fluid such as air or compressed oil.

Of course, when the elevating body is made of a piston, it is preferable to provide a water leakage prevention O-ring at the edge of the piston to prevent the fluid from leaking upward.

As shown in fig. 11, the tank of the present invention includes a water inlet pipe 110 on an upper side of the body and a water outlet pipe 120 on a lower side thereof to facilitate water inlet and outlet, and flexible joints 112 are provided on the water inlet pipe 110 and the water outlet pipe 120, respectively, to prevent breakage of the pipes even if the tank vibrates in a state where external pipes are connected (see fig. 21).

Further, as shown in fig. 20, a spiral blade 111 is formed on the inner circumferential surface of the water inlet pipe 110. The spiral blade 111 generates a rotational force in a process that water supplied to the water tank flows into the inside of the water tank, thereby enabling more rapid supply to the inside of the water tank, dispersing the water having flowed into the inside of the water tank by generating a vortex shape, and increasing the amount of oxygen-containing air in the water.

Of course, the water tank 100 of the present invention may be provided with a cover plate 100d on the upper side thereof so as to be openable and closable, and a ladder 100r on one side thereof so that an operator can go in and out through the cover plate.

Further, an exhaust port 100o is provided on the upper surface side, and air can be discharged when the internal pressure increases with an increase in the internal temperature.
