In general, a wall panel installed on the wall of the prefabricated bathroom (UBR), a ceiling panel installed on the ceiling, or a floor panel installed on the floor are made of FRP material, and the wall panel is combined with a toilet, a wash basin, and a bathtub. Since the panel of the FRP material is discolored and dirty as time goes by, and the durability is gradually weakened, the combined toilet and wash basin are often unable to withstand their own weight and are damaged.

The present invention relates to a method that can be quickly renovated without dismantling existing panels when the panels of the FRP material constituting the prefabricated bathroom discolored, damaged, or weakened. At this time, for easy description, the following description will be limited to the wall panel 10 to be repaired. And the renovation method applied to the wall panel 10 can be applied to the ceiling panel and the floor panel, of course.

In order to perform the remodeling method of the prefabricated bathroom, first perform the step of renovation level (S1) to prepare for the repair of the wall panel 10 of the FRP material is installed on the wall (W) of the prefabricated bathroom.

Opening level ratio step (S1) is a step to determine the current state of the wall panel 10 before the renovation. In step S1, it is a step of removing attachments such as bathtubs, sinks, toilet bowls, and silicon from the wall panel 10.

At this time, when the gap between the wall (W) and the wall panel 10 is excessively separated and nodding occurs, as shown in FIG. 3, the opening level ratio step (S1) is a hole in the wall panel 10. Through the injection of a foam, for example, foamed urethane foam (F) to perform a foam injection step (S-1) to prevent the flow of the wall panel (10). Foam injection step (S1-1) is carried out using commercially available foam urethane can (C).

Next, when damage occurs to the wall panel 10, a partial repair step (S2) for repairing the damaged portion is performed. Partial repair step (S2), if the damage to the wall panel 10, for example, if the cracked or damaged damage occurs, fill the damaged area with putty (putty), after which the putty is cured This step is to make the same surface as the other side of the wall panel by pepper work.

Next, a foreign matter removing step (S3) for removing foreign substances such as dust from the surface of the wall panel 10 is performed. Foreign material removal step (S3) is a step of rubbing the surface of the wall panel 10 with fine sandpaper or spraying fine sand or using a tile sanding disc. Through this foreign matter removal step (S3), not only the foreign matter is removed from the wall panel 10, but also fine scratches are formed, it is possible to increase the adhesion of the tiles 30, 30 'will be described later.

Next, a partition forming step S4 of forming a plurality of partitions 11 aligned with the wall panel 10 is performed.

When the tile 30 is adhered to the wall panel 10, it is necessary to align and evenly attach the tile 30 to improve the aesthetics of the bathroom as well as to improve the durability of the wall panel 10. For this purpose, before adhering the tile 30 to the wall panel 10, the position where the tile 30 is bonded should be partitioned to be aligned. Such a compartment forming step (S4) can be performed in various ways, as follows.

As shown in FIG. 2, the partition forming step S4 includes a plurality of blind spots that the operator can visually check on the wall panel 10 by using a wire (not shown) in the horizontal and vertical directions on the wall panel 10. It is a step of displaying the partition 11 of the form. That is, in the partition forming step (S4), the horizontal and vertical lines L are formed on the wall panel 10 by bouncing the ink lines in the horizontal and vertical directions, and the partitions 11 are displayed by these lines L. FIG. Alternatively, the partition forming step S4 is a step of forming a partition by the reference line by damaging the reference line (not shown) in the horizontal or vertical direction on the wall panel 10.

As described above, the partition 11 is formed in advance by the partition forming step S4, and the tiles 30 are attached to the wall panel 10 by adhering a plurality of tiles 30, 30 ′ based on the partition 11. Is glued in alignment.

In the partition forming step S4, as shown in FIG. 4, a partition formation in which a plurality of partition openings 41 are arranged in the center in the horizontal and vertical directions is arranged by the edge lines 43. It can proceed by adhering the edge 40 to the wall W. FIG. In this case, the plurality of partition openings 41 form a partition 11 ′ to which the tiles 30 are bonded to the wall panel 10.

As shown in FIGS. 5 and 56, the partition forming border 40 for performing the partition forming step S4 includes partition lines 42 formed in the horizontal and vertical directions, and edge lines 43 formed along the edges. Include. At this time, the width D1 of the partition line is twice the width D2 of the edge line. Therefore, as shown in FIG. 5, when the one bordering border 40 and the other bordering border 40 'are in close contact with each other, the width of the close edge lines 43 and 43' is equal to the partition line 42. Is the same as the width.

This is technically important. That is, a plurality of partition forming borders 40 are attached in advance according to the size of the wall panel 10. In this case, the tiles 30 are adhered through each of the plurality of partition openings 41 in which the partition forming borders 40 are formed. In other words, the partition line 42 and the edge line 43 form a joint boundary between the tile 30 and the other tile 30 '. At this time, the width of the joint should be constant for aesthetics, so that the widths of the edge lines 43 and 43 'closely contacted with each other should be the same as the width of the partition lines 42.

In addition, the partition line 42 and the edge line 43 support the self-weight of the tile 30 which is adhered to the wall panel 10 through the partition opening 41, so that the tile 30 is held while the adhesive is cured. It is prevented from being separated from the wall panel 10 by its own weight.

In this way, by using the partition forming border 40 described above, it is possible to align a plurality of tiles 30 adhered to the wall panel 10.

Next, a tile bonding step (S5) of bonding the plurality of tiles 30 to the partitions 11 and 11 ′ formed in the wall panel 10 is performed. The tile bonding step (S5) is a step in which a plurality of tiles 30 are adhered to the wall panel 10 to form a single body, thereby improving the durability of the wall panel 10 and cleaning it. At this time, the adhesive used for the tile 30 is the same component as the FRP wall panel 10, and the resin is preferably, for example, an unsaturated polyester resin (Unsaturated Polyester Resin).

On the other hand, a plurality of tiles (30, 30 ') can also be bonded in a zigzag form as shown in FIG. In this case, durability of the wall panel 10 can be further increased.

Next, a joint closing step (S6) of filling the joint formed between the plurality of FRP panels 30 and 30 ′ bonded to the wall panel 10 with mortar is performed. The joint closing step S6 is a step of filling the joint 35 formed between the tile 30 and the other tile 30 'with resin mortar.

FIG. 8 is a view for explaining the structure of a tile used in the present invention, FIG. 9 is a view for explaining filling the joint between the tile of FIG. 8 and another tile with mortar, and FIG. 10 is the tile of FIG. Figure for explaining the separation of release paper.

 The tile 30 is prefabricated in the form of tiles of several tens of centimeters in length at the factory, and may be made of various materials such as FRP material, aluminum material, stainless material, and resin material. Such a tile is composed of a tile body 31, a finishing layer 32 formed on the upper surface of the tile body 31, and a release paper 33 attached to the finishing layer 32, as shown in FIG. do. At this time, the finishing layer 32 is implemented as a gelcoat (Gelcoat), it can be polished or colored like glass can implement aesthetics such as ceramic tiles.

Gelcoats are paints for FRP surfaces that add pigments to unsaturated polyester resins to give a specific color. The finishing layer 32 of the gel coat protects the surface by finishing the surface of the tile body 31, and maintains the aesthetics not only to enhance and enhance the appearance, but also to enhance the durability of the tile body 31. Let's do it.

When using the tile 30 composed of the tile body 31, the finishing layer 32 and the release paper 33, the joint closing step (S6), the release paper 33 of the adjacent tiles (30, 30 ') ( The top surface of 33 ') is applied to the mortar using Hera to fill the joint 35 located between the release papers 33 and 33' with mortar (S6-1), and the mortar 35 is cured. If the release paper 33, 33 'includes a release paper separation step (S6-2) for separating from the finishing layer (32, 32').

At this time, since the width of the joint 35 is very narrow, as shown in Figure 9 in the process of filling the joint in the mortar using Hera. The upper surface of the adjacent release paper 33 (33 ') is to be dirty mortar (M). This messy mortar (M) is removed along with the release paper 33 (33 '), thus causing the mortar. 10 is neatly filled along the joint 35, as a result, it is possible to implement a clean prefabricated bathroom.

The mortar for filling the joint 35 is preferably a resin material interconnecting the tiles 30, 30 ', for example a gel coat, wherein the resin mortar is different from the edge of the tile 30. By adhering the edges of the tiles 30 'to each other, the wall panel 10 to which the tiles 30 are attached can be more firm.

Next, by performing the installation (S7) of the bath, toilet bowl, washbasin, etc. on the wall panel 10 to which the tile 30 is attached, the remodeling method of the prefabricated bathroom is completed.

In this case, a through hole through which the pipe of the facility is formed is formed in the tile attached to the lower side of the facility, such as a sink or a toilet, so that the tile is detached from the wall panel 10 so as to serve as a pipe inspection hole for checking the pipe. Can further improve the convenience of construction during replacement of the facility.

Thus, according to the prefabricated bathroom renovation method according to the present invention, it is possible to reduce the construction period by removing the wall panel without tearing, thereby alleviating the inconvenience of residents.

In addition, the recycling of wall panels and ceiling panels can prevent the generation of construction waste, thereby providing a method of retrofitting a prefabricated bathroom that can minimize environmental pollution.
