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

First, FIGS. 1 to 3 show a panel-mounted water tank (eg, a water tank of a synthetic resin structure) according to the present invention.

That is, as shown in FIG. 1 and FIG. 2, the panel-assembled water tank 1 of the present invention includes a panel 30 that is constructed in a structure 10 that largely constitutes a frame (frame) of the water tank, It can be configured as an example including a waterproof sheet 50 to be installed on the panel 30, and the adhesion reinforcing means 70 provided to increase the adhesive force between the panel and the waterproof sheet.

Therefore, the mall tank of the present invention, that is installed in the basement of an apartment or a large building to be stored to store a large amount of water, in particular, to solve the problems in terms of construction or maintenance of the existing concrete structure, and easy to install In particular, it is a panel-mounted water tank (PDF water tank) (1) which does not generate corrosion.

1 and 2, in the panel-mounted water tank 1 of the present invention, the structure 10 includes a frame 12 constructed on a foundation 16, that is, a foundation concrete block. It may be composed of a reinforcing body (14) coupled between the frame (12).

That is, the frame 12 is provided as an H beam in this embodiment, and a reinforcement body 14 such as a square pipe is bonded between the frames of the H beam to withstand water pressure even when a large amount of water is stored in the water tank. Is provided.

At this time, as shown in Figure 1, the color sheet 18 is constructed on the outside of the structure frame 12 and the reinforcement body 14, the cover plate 20 is installed on the upper, the cover plate and the color sheet Opening and closing port 22 and ladder 24 may be constructed, respectively.

On the other hand, although not shown separately in Figures 1 and 2, it is natural that the structure 10 is a floor frame (not shown) (plate) is installed on the base concrete block 16, the panels 30 are attached thereto thereon. .

Further, in the panel-mounted water tank 1 of the present invention, the panel 30 is attached to the water tank frame 12 (bottom and wall side frames) and the reinforcement 14 from the inside of the water tank. It may be provided as a hollow panel.

For example, in the present exemplary embodiment, the hollow panel 30 may have a structure in which plates 32 and 34 are bonded to both sides of the uneven portion 32. Of course, it is also possible to use an integrated hollow panel in which several through holes are formed in the center of one integrated panel.

On the other hand, such hollow panels 30, as shown in Figures 2 and 3a, the structure is not easily deformed even if the water pressure is applied to the panel after the construction of the water tank, in particular the inner hollow portion of the hollow panel heat transfer or noise Since it has a hollow part (space) which interrupts transmission, it is useful also for thermal insulation inside a water tank.

Next, in the water tank 1 of the present invention, the adhesion reinforcing means 70 is attached to the surface of the waterproof sheet 50 facing the panel 30, as shown in FIGS. 1 to 3. The nonwoven fabric, which is provided as a synthetic resin nonwoven fabric and which is the adhesion reinforcing means 70 of the panel 30 and the waterproof sheet 50, is bonded with an adhesive, as described in detail below.

For example, in the water tank 1 of the present invention, the waterproof sheet 50 serves to block leakage of water after the water is stored.

However, as described above, since the surface of the panel 30 is smooth, when the waterproof sheet 50 is previously attached to the surface of the panel, a problem arises in that the waterproof sheet is easily detached from the panel. In the case of the present invention, the non-woven fabric, which is the adhesion reinforcing means 70, in particular, non-corrosive non-woven fabrics of corrosion-resistant synthetic resins such as polyethylene that are adhered to each other, is bonded to maintain a strong adhesive strength, and thus the waterproof sheet 50 ) Is firmly attached to the surface of the panel 30 to prevent detachment.

Of course, the non-woven fabric of the adhesive reinforcing means 70 of such a non-woven fabric may be provided in advance in the manufacturing of the unit panel 30 and the synthetic resin waterproof sheet 50 of course.

At this time, preferably as shown in Figure 4 and 5, in the panel assembly type water tank 1 of the present invention, the adhesive to the panel member 30 and the waterproof sheet 50, the adhesion reinforcing means 70 When bonding non-woven fabrics made of synthetic resins such as polyethylene, which are bonded with a resin, a non-combustible thermoplastic resin, ie, a hot-melt adhesive (HM), heated and melted by heating to a high temperature state, is spray applied using a spray gun (G). After that, the non-woven fabric, which is the adhesion reinforcing means 70, is to be closely adhered to each other.

Therefore, the nonwoven fabrics of the adhesive reinforcing means 70 made of synthetic resin are entangled when the materials are entangled with each other due to the characteristics of the nonwoven fabric, but the adhesive strength is high. Through the hot-melt adhesive (HM) can be secured as well as adhesive strength can be maintained firmly.

And, when such a hot-melt adhesive is heated in the molten state and applied to the nonwoven in the form of a spray, it will be possible to complete the bonding operation of the nonwovens in a short time.

For example, as shown in Figure 4, using the spray gun G, as described above, to the non-woven fabric of the adhesion reinforcing means 70 adhered to the panel member 30 attached to the frame 10, As shown in Figure 5a, the application of the hot melt hot melt (HM) on top, and immediately bonded by pressing the non-woven fabric, the adhesion reinforcing means 70 of the waterproof sheet 50, and then in Figures 5b and 5c As shown in FIG. 3, the molten hot-melt adhesive is applied using a spray gun G to adhere the nonwoven fabrics tightly and firmly.

At this time, as shown in Fig. 5d, the hot-melt adhesive (HM) in the molten state that can be spray-injected using the spray gun (G), the solidified hot melt (HM ') in the heater (H) If the hot-melt is melted by heating to the desired temperature, the spray gun G can be sprayed.

Next, FIGS. 6 and 7 show other modifications including the adhesion reinforcing means 70 in the panel-mounted water tank 1 according to the present invention.

For example, in the case of FIGS. 6 and 7, the non-woven fabric, which is the above-described adhesion reinforcing means 70, may not correspond to a hot-melt adhesive, but may be applied using a conventional adhesive (C).

That is, as shown in Figure 6, in the water tank of the present invention, by increasing the coating amount of the adhesive (C) to the panel 30 or the waterproof sheet 50 to which the non-woven fabric, the adhesion reinforcing means 70 is attached, the nonwoven fabric It is also possible to have a valley 72 provided to increase the adhesive strength of the liver.

At this time, as shown in Figure 6, such a valley portion 72 may be formed on the nonwoven fabric attaching surface of one side plate 34 of the panel 30, or may be provided on the nonwoven fabric bonding surface side of the waterproof sheet 50. Do.

That is, the bone portion 72, when the adhesion strengthening means 70 of the thin nonwoven fabric is bonded to the bone 72 of the panel or the waterproof sheet, the bone is formed on the outer surface of the nonwoven fabric, and thus, when the waterproof sheet is attached and A space is formed between the sheet side nonwoven fabric and the ribbed panel side nonwoven fabric, so that the remaining amount of adhesive C remains in the space more than the flat one.

As a result, since the residual amount of the adhesive increases, the adhesive strength between the nonwovens is more firmly maintained, which effectively blocks the panel detachment of the waterproof sheet 50 attached by the nonwoven fabric as well as the nonwoven fabric.

On the other hand, as shown in Figure 7, in the water tank of the present invention, one side plate 34 of the panel 30 or the facing sheet 50 does not form a valley as shown in Figure 6, the step with the nonwoven fabric In order to form, the adhesive reinforcing means 70 is to attach the tape 74 to one surface of the panel or waterproof sheet to which the nonwoven fabrics are attached.

Therefore, as shown in FIG. 7, a space is formed between the tape 74 and the nonwoven fabric, but a space is small, and such a space increases the application amount of the adhesive C as described above with reference to FIG. 6. It is possible to form a space, and to increase the amount of adhesive (C) remaining in such a space, and eventually the adhesion of the nonwoven fabrics is increased, the panel detachment of the waterproof sheet 50 is effectively prevented.

Next, FIG. 8 illustrates a construction state at the joint portion P in which the unit waterproof sheets 50 overlap in the panel assembly type water tank 1 of the present invention.

For example, as shown in FIG. 1, the panel-mounted water tank 1 of the present invention is a large water tank, and in fact, since several unit waterproof sheets 50 are attached to the panel from the inside, FIG. As such, the joint portion P, where the unit waterproof sheets overlap each other, is firmly constructed by using a separate seat fixture 90.

That is, as shown in FIG. 8, the sheet fixing device 90 which is screw-assembled to the panel 30 without attaching the non-woven fabric, which is the adhesion reinforcing means 70, to the joint portion P where the unit waterproof sheets 50 overlap each other. It is to be fused at high frequency through the medium.

In this case, as shown in FIG. 8, the sheet fastener 90 has a structure in which a synthetic resin layer 94, for example, polyethylene (PE) is coated on the surface of the stainless plate 92 having less corrosion, and is screwed to the panel. When fixed, applying a high frequency to the high frequency generator (T) to the adhesive portion (P) overlap unit waterproof sheets thereon, heat is generated by the shaking of the stainless plate of the fixture, the synthetic resin layer coated on the fixture 94 ) And fusion bonding of the waterproof sheet joints overlapped with each other.

As such, the adhesive portion of the waterproof sheet may be formed even between the side wall and the bottom.

Next, in FIG. 9, in the panel assembly type water tank 1 of the present invention, the pipe member 110, that is, the pipe member 110 such as a supply pipe for supplying water into the tank, a drain pipe for cleaning the inside of the tank, or the like. ) May be constructed through the panel 30.

Therefore, in the case of the present invention, while welding the pipe member 110 through the panel welding (W) for welding the synthetic resin welding material with hot air.

That is, the watertight sheet is tightly sealed so that moisture (water) does not penetrate through the waterproof sheet 50 having a hole formed therethrough.

Of course, in the region where the pipe member 110 penetrates the panel as shown in FIG. 9, in the present invention, the synthetic resin waterproof sheet 50 and the panel 30 are interwoven with a nonwoven fabric, that is, adhesion reinforcing means 70 is closely adhered thereto. Therefore, in the case of the present invention, the waterproof sheet detachment is not generated at the portion where the pipe member penetrates.
