Description

Method for manufacturing waterproof plate molding frame and waterproof plate {Stopwater plate molding frame and Mehtod for making stopwater plate}

The present invention relates to a waterproof product of the bathroom used in the UBR (Unit Bach Room) assembly method, and more specifically, in the manufacture of a waterproof plate installed on the floor of the bathroom used in the UBR assembly method according to the size of the bathroom floor It relates to a waterproof plate manufacturing method that can be transformed into dimensions.

In the past, conventional bathrooms do not have their own thermal insulation and each manufacturer is different, so it is impossible to supply them collectively at the construction site, and the construction process is complicated due to the distributed construction, which delays the construction period and increases labor costs. There was this. In order to solve this problem, a UBR (Unit Bach Room) assembly method, which is a method of manufacturing a product in a factory and assembling it on site, has been developed.

In general, the UBR (Unit Bach Room) assembly method means that all components of the bathroom (floor, wall, ceiling, etc.) and parts (wash basin, bathtub, toilet, etc.) are produced and processed at the factory and assembled at the construction site. This is a method of completing a prefabricated bathroom.

The prefabricated bathroom of UBR assembly method does not need additional waterproofing work, and uses FRP (Fiber Reinforced Plastics) waterproof plate which can be freely molded and has high strength. Since prefabricated bathrooms rarely process parts and parts in the field, are very simple to construct on site, and require only prefabricated bathroom assemblers, there is no need for process coordination between technicians and high quality parts produced uniformly in the strict factory. Use of the bathroom is excellent quality.

In addition, it is possible to check the condition of the completed bathroom in advance with the naked eye, and it is very easy to maintain and maintain because it is possible to replace the wall, floor, ceiling, etc. using the prefabricated method.

However, despite these many advantages, many problems have arisen in manufacturing. The FBR floor plate used in the prefabricated bathroom is manufactured by press processing, so the molding frame of the FBR floor plate is made of wooden mold and FRP mold.

Bathrooms vary in size and shape, and in order to produce such various types of bathrooms, various types of floorboards must be manufactured. Each time, various molding molds, such as a wooden mold and a FRP mold, are required. As it is not greatly reduced, it is not used much by the construction company yet. That is, the mass production of various products is difficult due to the de-standardization of the bathroom.

The present invention has been made to solve the conventional problems as described above, to minimize the production of the waterproof plate forming frame in the process of manufacturing the waterproof plate used in the prefabricated bathroom and to deform or mix the shape of the waterproof plate The purpose of the present invention is to provide a method of manufacturing a waterproof plate capable of mass-producing prefabricated bathrooms by shortening production costs and construction period.
