Excellent friction coefficient due to high plating layer hardness, excellent processability It has the ability to inhibit progression.

The POSMAC panel 50 of the present invention has a structure in which water resistance and waterproofness are further improved by thermally fusion of a PE sheet (PE) having a certain thickness to the inner surface of the POSMAC (P) on which the surface strength reinforcement embossing is formed as described above. It is characterized in that it is made by attaching a heat insulating material (PU) to the outer surface.

In general, polyethylene is a synthetic resin with excellent mechanical strength, thermal properties, chemical resistance, tear rupture strength, good thermal adhesion and workability, and particularly excellent moisture resistance. It is characterized in that it enhances the functionality of the water tank 100 by further reinforcing the high corrosion resistance of the Posmac (P) by allowing the PE sheet (PE), which has excellent waterproof properties, to come into contact with water by attaching it to the surface by heat-sealing it.

In addition, in the center of the inner surface of the POSMAC panel 50 for solid bonding of the PE sheet (PE), the mounting reinforcing plate 70 consisting of a central concave portion 70a and a convex portion 70c having a plurality of resin penetration holes 70b drilled therein. ) is attached and the molten PE resin is injected into the space between the inner surface of the Posmac (P) through the resin injection hole when the PE sheet (PE) is heat-sealed, so that the PE sheet (PE) is made into the Posmac panel ( 50) to be bonded to the inner surface of the

This is because when the PE sheet (PE) is bonded to the inner surface of the Posmac (P) by thermal fusion, the molten PE resin penetrates into the resin penetration hole (70b) of the mounting reinforcing plate (70), and the cross-section shown in FIG. It also provides a riveting effect to prevent separation of the PE sheet (PE).

In addition, the wall part 300 assembled on the upper surface of the base part 200 to form the outer wall of the water tank 100 has a PE sheet (PE) attached thereto and embossed for strength reinforcement as described above. It is made of four-way assembly of the Mac panel 50, and the Posmac panel 50 has a flange 51 bent outwardly on its outer periphery, so that the adjacent Posmac panel 50 is the flange 51. It is assembled by joining and fastening, and reinforcing flanges 52 and 52' are joined up and down together with the gasket 53 to the flanges 51 on all sides where the joint is fastened, so that the bolts 54 are watertightly and tightly fastened and assembled.

And the external reinforcement structure 500 installed in the vertical direction to the reinforcing flanges 52 and 52 ′ that vertically fasten the Posmac panel 50 to the outer surface of the wall part 3000 is the wall part 300 is stored therein. It is prevented from being deformed to the outside by the water pressure of water, and the external reinforcement structure 500 extends over the entire height of the wall part 300 as shown in FIG. 8 .

The vertical reinforcing channel 55 of the shape is symmetrically fastened to the reinforcing flanges 52 and 52' to form the deformed H-shaped external reinforcing structure 500, as shown in FIG. 10, the external reinforcing structure 500 The lower part of the base part 200 is fastened with a bracket 56 to the pillar member 11, and the upper part is fastened to the ceiling steel bar 80 of the ceiling part 400 so that the wall part 300 faces vertically. It is reinforced by a plurality of mutually supported external reinforcing structures 500 to prevent deformation to the outside by water pressure.

When the height of the water tank 100 is low, the external reinforcing structure 500 can be installed as a single unit, but when the height of the water tank 100 is high, it can be implemented in a structure in which two or more are separated and connected in the longitudinal direction. In this case, as shown in FIG. 13, the external reinforcement structure 500 made of the vertical reinforcement channel 55 is separated into two or more, and the front plane part 57 of the connection part and the concave part 57' on both sides are respectively When the front connecting plate 58 and the U-shaped inner connecting plate 59 are joined and fastened as a bolt 54, the separated external reinforcing structure 500 is assembled as a long-length unitary body.

Therefore, when the space for installing the water tank 100 is narrow, the external reinforcement structure 500 can be efficiently installed, and transport and handling are also effective.

In addition, since the water tank 100 has a difference in water pressure depending on the height, the POSMAC panel 50 constituting the wall part 300 of the present invention does not form the entire POSMAC panel 50 of the same thickness, but the water pressure It is installed as a POSMAC panel 50 that is thicker from the upper part receiving less to the lower part receiving a lot of water pressure.

FIG. 2 shows an example of the difference in thickness of the POSMAC panel 50. When the lowermost panel fastened to the base 200 has a thickness of 5.5t, the upper portion thereof is thinner with a thickness of 4.5t. Even if it is configured with a thickness that gradually becomes thinner toward the upper part, it has sufficient hydraulic pressure support according to the hydraulic pressure difference according to the difference in height. This difference in thickness is adjusted according to the capacity and size of the water tank 100 .

In addition, at each corner of the wall part 300, the reinforcement plate 91 is orthogonally fastened to the transverse flange 51b of the neighboring Posmac panel 50 assembled orthogonally, and the reinforcing plate 91 is erected orthogonally at the intersection thereof. A corner reinforcement bar 90 composed of a corner support 92 that is fastened to the corner angle 93 of the vertical flange 51a of the Posmac panel 50 that has been interviewed is fixedly installed.

The corner reinforcement bar 90 is firmly fixed to the transverse flange 51b in which the orthogonally branched reinforcement plate 91 intersects while the corner support 92 is coupled to the corner angle 93, so the wall part 300 ) to more firmly support the edge of the POSMAC panel 50 that intersects, thereby assisting in forming a solid wall part 300 .

A plurality of ceiling steel bars 80 are assembled to the outside of the ceiling portion 400, which are fastened with the POSMAC panel 50 constituting the ceiling and reinforced in a lattice form, and both ends of the ceiling steel bars 80 are the walls. It is firmly connected to the upper end of the external reinforcement structure 500 facing the part 300 to reinforce the entire exterior of the water tank 100 made of the Posmac panel 50 .

The present invention as described above has the following effects.

First, the panel constituting the water tank 100 is composed of Posmac (P), which is a high corrosion-resistant steel sheet, but a PE sheet (PE) is attached to the inner surface of the Posmac (P) by thermal fusion to form Posmac (P). By avoiding direct contact with this water, the high corrosion resistance of the POSMAC panel 50 is further reinforced, thereby increasing the waterproofness and thus increasing the lifespan of the water tank 100 very long.

Second, the POSMAC panel 50 is constructed from a thicker panel to a thinner thickness as the water tank 100 goes from a lower portion that receives a lot of water pressure to an upper portion that receives less water pressure according to the height of the water tank 100 while maintaining the water pressure support. It has the effect of reducing weight and cost.

Third, the base part 200, the wall part 300, and the ceiling part 400 constituting the water tank 100 are firmly coupled to one another, and the exterior connected to the outside of the wall part 300 by disassembly and assembly.
