Antibacterial PE sheet and dry pad integrated non-welding, non-reinforced PDF earthquake-resistant water tank using the same}

The present invention relates to a copper antibacterial PE sheet and a dry pad-integrated non-welding, non-reinforced PDF seismic water tank using the same. It relates to an antibacterial PE sheet and a dry pad-integrated non-welding, non-reinforced PDF seismic water tank using the same.

In general, a water tank is a storage container that stores a certain amount of water inside and supplies it to buildings that use a lot of water for living, such as residential apartments and business buildings.

The water tank is classified into a stainless panel water tank, an SMC panel water tank, and a concrete water tank according to the material.

The stainless panel water tank has an uneconomic problem due to an increase in the price of raw materials, the synthetic resin panel water tank has a weak durability problem, and the concrete water tank has excellent structural strength and durability corresponding to water pressure or bending load, but the construction process There was a problem that not only was this complicated, but also the construction period was long.

So, recently, PDF (Polyethylene Double Frame) water tanks that are easy to install while sufficiently responding to water pressure and bending loads generated inside the water tank while supplementing the problems of the stainless panel water tank, SMC panel water tank, and concrete water tank have been widely used. is being constructed.

Accordingly, first, as an example of a conventional PDF water tank, the "PDF water tank" (hereinafter referred to as "conventional PDPF water tank") of Korean Patent Registration No. 1269437, which the present applicant previously applied for and registered, is known.

A conventional PDF water tank has a bottom part formed by seating a bottom plate on a frame seated in a grid shape on the upper surface of a plurality of concrete foundations, and a vertical support member on the concrete foundation so as to be in close contact with each corner and bottom side of the bottom part. A side wall portion formed by closely adhering a side plate to a horizontal support member seated and spaced apart from the vertical support member and fixed to the vertical support member, and an upper plate portion that is supported by the vertical support member and closes the upper part of the water tank formed in the shape of a housing include

However, in the conventional PDF water tank, a grid-type frame constituting the floor is manufactured through welding connection of frames at the construction site, and both ends of each horizontal support member are welded to the vertical support member to form a water tank. construct

Therefore, when constructing a conventional PDPF water tank at a construction site in a building, the grid-type frame constituting the floor is manufactured through welding and the horizontal support member is connected by welding, so that welding work at the construction site There was a risk of fire due to this, and when an earthquake occurred, cracks were generated around the welding part of the frame or horizontal support member, thereby reducing the seismic performance of the water tank.

In addition, as the conventional PDPF water tank is manufactured through the connection of a grid-type frame that takes a lot of time by welding and the horizontal support member is connected by welding that takes a lot of time, the construction of the water tank at the construction site takes a lot of time. There were also problems.

In addition, the conventional PDPF water tank has a problem that it takes a lot of time to manufacture the vertical support member at the corner by connecting two H-beams at right angles through welding, and manufacturing the vertical support member at the corner. There was also a problem in that the seismic performance of the water tank was deteriorated as cracks were generated around the welding part of the H-beam.

On the other hand, the PE sheet, which is lined on the inner surface of the conventional PDF water tank and plays a waterproof role, is made of polyethylene, a plastic material that is harmless to the human body. It has excellent drug properties.

However, since the PE sheet attached to the inner surface of the conventional PDPF water tank and used as a waterproof sheet is made of only polyethylene, the antibacterial effect of antibacterial effect of water filled in the water tank cannot be expected at all.

Next, the PDF seismic water tank construction according to the present invention is completed through the process of attaching the copper powder mixed PE sheet 7 to the inner surface of the PDF bottom plate 5 and the PDF peripheral plate 6 .

Therefore, the present invention is a useful invention that can also obtain the antibacterial effect of copper by lining the inner surface of the PDF seismic water tank with a copper powder mixed PE sheet 7 having an antibacterial effect of copper and making it come into contact with water.

In addition, the present invention constructs the water tank 10 only by assembling without welding, thereby preventing a fire due to welding at the construction site and reducing the construction time of the water tank 10 at the construction site. It is a useful invention to provide a water tank.

In addition, the present invention prevents the occurrence of cracks in the assembly connection portion of the bolts when an earthquake occurs by connecting the water tank 10 in a prefabricated manner through the fastening of bolts, thereby improving the seismic performance without additional reinforcement inside. It is a useful invention that can provide an internal non-reinforced, non-welded PDF seismic water tank.

Although preferred embodiments of the present invention have been described above, various changes, modifications and equivalents may be used in the present invention. It is clear that the present invention can be equally applied by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention defined by the limits of the following claims.

On the other hand, although specific embodiments have been described in the detailed description of the present invention, it will be apparent to those of ordinary skill in the art that various modifications are possible without departing from the scope of the present invention.
