The present invention is capable of various modifications and various embodiments, and specific embodiments are illustrated in the drawings and described in detail with reference to the drawings. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

Like reference numerals are used for like elements in describing each drawing. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention not only prevents the ceiling from being corroded by chlorine gas, but also blocks external cold or warm air, so that the water in the tank can always maintain a constant temperature.

The ceiling-reinforced water tank according to the present invention is a water tank constructed by installing a ceiling board on the top of a wall formed by connecting a plurality of wall panels 200 on a base 100 like a normal water tank.

The ceiling reinforcing structure according to the present invention is shown in FIG. 2 as an example of a water tank assembled by welding (200w) end portions of coupling vanes bent inward to the wall panel 200. However, as shown in FIG. 3, A reinforcement structure may be provided on the outside or a water tank in which the end portion of the wall panel is assembled with bolts, though not shown.

By reinforcing the ceiling plate 10 constituting the water tank, the ceiling plate is prevented from being corroded by the chlorine gas used in disinfecting the water stored in the water tank.

The ceiling plate 10 includes a steel plate 11 having a coupling wing 11w to which the fixing bolts are fastened by bending the edges of the plate to the outside; And an anticorrosion layer 12 laminated on the surface of the steel sheet facing the inside of the water tank and having a coupling vane portion 12w extended to the outer surface of the coupling vane portion 11w.

As shown in FIG. 6, the ceiling plate 10 may be formed in a square shape, but may be formed in a triangular shape or a multi-shape shape.

The steel plate 11 may be formed by bending or injecting a plate-shaped metal plate, and is made of a material that is resistant to moisture and chlorine and is not bent easily.

A preferable example of the steel sheet 11 is a coated steel sheet, which is formed by plating an alloy including aluminum, magnesium and zinc on a hot-rolled steel sheet.

The anticorrosion layer 12 is laminated on the surface of the steel plate 11, that is, the surface facing the inside of the water tank.

The anticorrosion layer 12 may be made of various materials having water resistance and chlorine resistance, but is preferably made of a PE resin harmless to the human body.

The anticorrosion layer 12 may be formed by applying a PE resin liquid several times to the surface of the steel sheet 11 and then hardening it. However, when the PE resin solution is coated, it is thin and easily damaged, It is necessary to repeatedly apply the PE resin solution repeatedly several times. However, in order to repeat the application of the PE resin solution, an excessively long time is required for the production, and foreign matter may be adhered during the curing process.

Accordingly, it is preferable that the anticorrosion layer 12 is laminated on the surface of the steel sheet by adhering a PE film having a predetermined thickness with an adhesive 12b.

The thickness of the anticorrosion layer 12 is preferably at least about the thickness of the steel sheet. If the thickness of the backing layer is excessively thin, perforation may occur as time elapses, and if it is too thick, it may be separated from the steel sheet during the bonding process.

2 and 4 to 6, it is preferable that the abutment layer 12 is extended to the coupling wing portion 11w of the steel plate 11. As shown in FIG.

As shown in FIG. 2, the ceiling plate 10 of the present invention has a structure in which a bolt 15 is passed between neighboring coupling vanes and a nut is tightened to couple two neighboring roof plates, Since the breakwater layer 12 is formed between the coupling vanes 11w, the coupling vane 12w of the vibration-proof layer serves as a packing so that no gap is formed between the adjacent ceiling plates, Is prevented from flowing into the water tank, and the residual chlorine gas does not affect the steel sheet in the process of being discharged to the outside.

Further, the water tank of the present invention is further laminated with a heat insulating material 13 on the ceiling plate so as to prevent heat from being absorbed or released from the ceiling.

The heat insulating material 13 is laminated on the outer surface of the steel plate 11 as shown in Figs. 2 and 4 to 5.

In the winter season, the heat insulating material 13 blocks the inflow of outside air into the inside of the water tank. In the summer, it prevents the outside air from flowing into the nighttime tank, To receive less.

The heat insulating material 13 may be made of various materials, but preferably any one of styrofoam, urethane foam, urea foam and air cap film may be used.

When the heat insulating material 13 is exposed to the outside, it may be naturally corroded to deteriorate the heat insulating effect. Thus, the heat insulating finishing material 14 is further laminated on the surface of the heat insulating material 13.

The heat insulating finishing material 14 can be made of a heat insulating metal or resin and can be made into a plate having corrosion resistance that is not corroded by sunlight, snow, or rain.

As shown in FIG. 1, the water tank having the above-described roof plate 10 is provided with a manhole 20 for entering and exiting the manager, and the manhole 20 is provided with an opening It is preferable that the lid guide 21 is provided on the outer surface of the ceiling plate and the manhole cover 22 is provided so as to be opened and closed by sliding along the lid guide.

That is, it is preferable that the lid guide 21 is provided with a rail groove, and a sliding member is provided on the inside of the manhole cover so as to move along the rail groove, so that the manhole cover is horizontally moved and opened.

In addition, it is preferable that a part of the ceiling plate is provided with an air vent 30 formed therein.

The air vent 30 prevents the water tank from expanding by discharging the air when the water stored in the water tank evaporates in the summer and the pressure inside the water tank becomes high. In the winter season, the water stored in the water tank is cooled When the pressure inside the water tank is lowered, the air is sucked to prevent the water tank from being shrunk.

The air vent 30 may be any one of various air vents which are provided to allow air to flow in and out of the water tank.

In the water tank of the present invention constructed as described above, a plurality of wall panels 200 are assembled together to form a wall, and the ceiling panel 10 is installed at the top of the wall.

As shown in FIG. 1, the wall panel 200 is a wall of a water tank, and various panels having heat insulating properties can be used. Preferably, the panel panel 200 is a thermal storage unit panel developed by the present applicant. A heat storage material sheet attached to an upper portion of the heat storage material sheet, a heat insulation cover attached to an upper portion of the heat storage material sheet, and a surface layer coupled between the heat storage material sheet and the heat insulation cover to absorb or emit heat . The surface layer may also be a metal foil layer formed by laminating any one of aluminum foil and copper foil having a high heat transfer rate as an intermediary for transferring heat between an object to be absorbed or discharged.

Of course, when the height of the molten tank is high, as shown in FIG. 1, a ladder 300 may be installed on one side to facilitate the entrance and exit of the manager.
