The present invention relates to a concrete water tank remodeling member and a remodeling method thereof, and more particularly, a concrete body remodeling member and its remodeling, in which a plate body surrounds an inner surface of a concrete water tank and is firmly adhered to it, and is easily and easily sealed between plates. It is about public law.

In general, a tank (water tank) is widely used to store a large amount of water in apartments, schools, buildings, factories, and the like.

The tank is manufactured in a cylindrical shape using concrete or synthetic resin. In recent years, many tanks have been developed by connecting a plurality of panels and assembling them into a tubular shape.

In the case of concrete tanks among the various types of water tanks as described above, problems such as water leakage due to cracking or harmful components are generated due to corrosion due to long-term use, such as polluting water.

Particularly, in the concrete water tank, when the coating is applied to the inner surface to form a coating, the environmental hormone may be induced upon incomplete curing of the epoxy used as the coating, and thus may adversely affect the human body when drinking water or contacting the skin.

In addition, since the durability of the film is easily degraded and peeling phenomenon occurs frequently, periodic maintenance work for forming the film is necessary.

Therefore, the maintenance work is cumbersome and expensive maintenance costs in the long-term, there is a need for fundamental measures to solve these problems.

Conventionally, in order to solve the above problems, there is a case of remodeling by enclosing the inner surface of the concrete tank by connecting several panels with bolts, but the construction is inconvenient and the flange portion formed on the panel for bolting is connected to the inside of the tank. Projections are exposed to various problems, such as foreign matter is easy to remain and difficult to remove the foreign matter during cleaning.

The present invention has been made in view of the above points, the plate is firmly fixed to the inner surface of the concrete tank, and tightly fixed using a fastener so that the seal is well maintained, and the sealing and the finish between the plate using a seal simply to perform a simple To provide a possible concrete tank remodeling member and its remodeling method.

In the above it is also possible to further install a secondary sealing body between the concrete tank and the plate body.

The plate body has a plurality of fixing holes for fixing the plate body by using the fixing tool at predetermined intervals along the plate surface, and a fixing groove is formed around the fixing hole.

In the above, by forming a chamfer at the edge of the plate body, it is also possible to form a "V" shaped sealing groove in which the sealing body is pressed and installed between the edges of the plate bodies located next to each other.

In addition, it is also possible to form the plate joints which are assembled to be engaged with each other in the step shape or "ㅏ" shape on the edge of the plate located adjacent to each other in the above.

In the above, the sealing member is press-fitted between the joints.

The fastener has a female screw hole is formed and the fixing anchor is fixed to the concrete tank through the fixing hole of the plate body, the bolt is fastened to the male screw hole in the female screw hole of the fixing anchor, and the fixing groove of the plate body And a cap member surrounding the head of the bolt, and a sealing member installed between the fixing groove of the plate body and the cap member.

In the cap member is made of a synthetic resin, one side is made of an open cylindrical shape and the other side is formed with a through hole through which the male screw shaft of the bolt passes.

The cap member may be provided with a cap which is assembled while sealing the opened one side.

The seal is made of butyl rubber.

The sealing closing member comprises a body made of a synthetic resin film and formed in a band shape and a coating layer is formed on one side, and an adhesive layer applied on the coating layer and adhering the body to the plate and the sealing body. .

And the present invention is formed by the edge of the plate body is formed in a step shape is formed between the sealing grooves are installed between the edges of the plates located adjacent to each other, the sealing closing member is closed and sealed to seal the sealing groove It is also possible to be inserted into a groove and assembled to form a cover to cover the seal.

The sealing closing member is formed in the shape of a rod and is formed in the "C" cross-sectional shape.

In addition, the concrete tank remodeling method proposed by the present invention includes a drilling step of drilling the anchor hole in the concrete tank by passing the plate body in which the fixing hole is formed to the inner surface of the concrete tank and passing through the fixing hole, and the fixing anchor in which the female screw hole is formed. A plate fixing step for assembling the male screw shaft of the bolt with the sealing member assembled into the female screw hole of the fixing anchor after being fixed in the anchor hole, and pressing and installing a seal between the plate and the plate. And a sealing step of performing sealing, and a sealing closing step of adhesively fixing the sealing closing member along the edge of the plate body while covering the sealing body.
