Bathroom dry floor system {Floor system for bathroom}

The present invention relates to a bathroom dry floor system in which a bed mortar formed by pouring floor mortar on an upper part of a bathroom floor slab and a waterproof panel are sequentially positioned, and more particularly, it is dried to minimize the wet process during bathroom floor construction. Therefore, it is about a bathroom dry floor system that is easy to install and can shorten the construction period.

In general, the bathroom of the apartment house is installed in the order of forming a waterproofing layer 20 by installing an insulating material on the concrete wall, wet construction of the masonry wall, and then applying a waterproofing solution on the surface of the masonry wall and the upper part of the floor slab 10.

When the waterproof layer 20 is formed by this separate waterproofing process, a waterproof protection mortar 30 with a thickness of about 20 mm is installed on the waterproof layer 20, and a bed mortar 40 is poured on the waterproof protection mortar 30 And curing and construction, after that the wall tiles are constructed, the adhesion mortar 50 is poured on the floor, and then the floor tiles 60 are installed as a finishing material (FIG. 1).

Bathroom construction by such a wet method takes a lot of construction time, there is a problem of delay in construction due to the need for a curing period, and there is a risk of quality deterioration during construction in the winter season.

In addition, the bathroom floor creates a gradation on the floor for drainage. However, since the conventional wet method forms a gradient by the bed mortar 40, there is a problem that a quality difference may occur depending on the skill level of the operator.

In order to improve the above problems, the UBR (Unit Bathroom) method, a dry bathroom structure in which floors, walls, ceilings, and internal facilities are made in the form of a booth made of waterproof materials such as FRP, and installed on site, has been developed.

However, in bathroom construction using the UBR method, it is difficult to cope with various flat dimensions because the entire booth is pre-produced in the factory by mold, so cutting or modification on site is not possible. In addition, there is a difficulty in absorbing construction errors that occur during frame construction. In addition, when the bathroom deteriorates, the entire booth must be replaced, and the image of low-cost materials is strong, which lowers consumer preference.

Accordingly, the applicant has succeeded in developing and commercializing a technology for a bathroom dry waterproof structure in which the bathroom wall is dried to improve the finishing quality and secure excellent waterproof performance and workability (Registration Patent No. 10-1982188).

However, in the case of the bathroom floor, there are still parts that depend on the conventional wet method, such as a separate waterproofing process must be input and a bed mortar for forming a floor gradient must be installed, so there is a limit to shortening the construction period and securing waterproof quality during bathroom construction.

In order to solve the above problems, an object of the present invention is to provide a bathroom dry floor system that can be dried to minimize the wet process during bathroom floor construction, so that construction is simple and the construction period is shortened.

As shown in Figure 2, the present invention bathroom dry floor system is a bed mortar layer (2) provided on the bathroom floor slab (1); It consists of a high-density EPS or high-density XPS board body 31, an inorganic primer layer 32 applied on the top of the board body 31, and a protective mortar layer 33 provided on the primer layer 32, a waterproof panel 3 adhered to the top of the bed mortar layer 2; and a finishing material (4) attached to the upper portion of the waterproof panel (3) by an attachment mortar (41); It is characterized in that it is composed of

An object of the present invention is to provide a bathroom dry floor system that is simple in construction and can shorten the construction period by drying the bathroom floor structure to minimize the wet process.

The present invention bathroom dry floor system is configured to include a bed mortar layer (2) and a waterproof panel (3).

The bed mortar layer (2) is formed by pouring mortar on the upper part of the bathroom floor slab (1), which is a reinforced concrete frame, without a separate waterproofing construction.

Since the top surface of the floor slab 1 may be uneven, a bed mortar layer 2 is installed thereon to make the top surface of the floor even.

The bed mortar can be cast once, and the material has high fluidity, so self-leveling is possible. Therefore, it is possible to adjust the smoothness of the upper surface of the bed mortar layer (2) without a separate planarization operation.

The bed mortar can be used at the same time when pouring pipes in a household, so that wet construction can be completed early.

When the mortar is cured and the construction of the bed mortar layer 2 is completed, the waterproof panel 3 having its own waterproof performance is adhered to the upper portion of the bed mortar layer 2 .

The waterproof panel 3 can be adhered to the upper surface of the bed mortar layer 2 by applying an adhesive to the lower surface in the field.

A finishing material 4 such as a floor tile may be attached to the upper surface of the waterproof panel 3 after the attachment mortar 41 is applied.

At this time, the finishing material 4 is not installed on the waterproof panel 3 of the bathtub (BT) part.

The waterproof panel 3 has a smooth upper surface and excellent tile adhesion. Therefore, it is possible to directly attach the finishing material (4) after applying a thin-walled attachment mortar (41) to the upper part of the waterproof panel (3) without placing a separate bed of mortar.

Since the waterproof panel 3 secures waterproof performance by itself, it is possible to omit the on-site floor waterproofing process during actual construction. In addition, since the finishing material 4 can be directly attached to the upper part of the waterproof panel 3, the bed mortar process can be omitted. Accordingly, it is possible to minimize wet construction and shorten the construction period, and it is advantageous for construction in the winter season.

The bathroom dry floor system of the present invention can be constructed in the following order.

First, the floor mortar is poured on the upper surface of the floor slab 1 and cured to form the bed mortar layer 2 .

And after applying an adhesive to the lower part of the waterproof panel (3), the waterproof panel (3) is attached to the upper surface of the bed mortar layer (2).

Thereafter, the finishing material (4) is installed on the upper part of the waterproof panel (3) to finish it.

3 is a cross-sectional view showing an embodiment of a waterproof panel.

As shown in FIG. 3 , the waterproof panel 3 is a board body 31 , a primer layer 32 applied on the board body 31 , and a protection provided on the primer layer 32 . It can be configured as a mortar layer (33).

The board body 31 is for securing rigidity and waterproof performance of the waterproof panel 3 and forming a gradient.

The board body 31 may use expanded polystyrene (EPS), eXtruded polystyrene (XPS), etc. to secure sound insulation and thermal insulation performance. In particular, EPS or XPS are lightweight and easy to process on-site, such as cutting, making it easy to respond to plane variability.

In order for the board body 31 to secure the necessary strength and hardness as a bottom plate, it is preferable to use high-density EPS or high-density XPS.

A plurality of grooves 311 may be formed on the lower surface of the board body 31 to a predetermined depth in order to improve adhesion with the bed mortar layer 2 .

The primer layer 32 is formed by being applied to the upper portion of the board body 31 .

The primer layer 32 is for securing the waterproof performance of the waterproof panel 3, and gives the waterproof performance to the panel itself. Accordingly, a separate waterproofing process in the field can be omitted.

When high-density EPS or high-density XPS is used as the board body 31 , the high-density EPS or high-density XPS corresponds to an organic product, and thus the board body 31 may melt when a general organic primer is used.

Therefore, the board body 31 of the high-density EPS or high-density XPS uses an inorganic primer to form the primer layer 32 .

The protective mortar layer 33 is provided on the primer layer 32, and secures the surface hardness of the waterproof panel 3, and improves the walking feeling of the user.

Fig. 4 is a plan view showing an embodiment of a shared bathroom, and Fig. 5 is a plan view showing an embodiment of the couple's bathroom. And FIG. 6 is a cross-sectional view taken along line A-A' of FIG. 4 , and FIG. 7 is a cross-sectional view taken along line B-B' of FIG. 5 .

4 to 7, the bed mortar layer 2 of the bathroom floor has a first floor surface 1a on which a bathtub BT or a shower booth SB is disposed, and a second floor surface that is the remaining part. Divided into (1b), the waterproof panel 3 is provided on the first waterproof panel 3a and the second bottom surface 1b provided on the first bottom surface 1a, the first waterproof panel (3a) It can be divided into a second waterproof panel (3b) that becomes thinner toward the side and forms a gradient in one direction.

The waterproof panel 3 may be divided into a first waterproof panel 3a on the first bottom surface 1a and a second waterproof panel 3b on the second bottom surface 1b.

That is, the bathroom is divided left and right into a first floor surface 1a, which is a portion where a bathtub BT or a shower booth SB is disposed, and a second floor surface 1b, which is a portion where a washbasin and toilet requiring a floor gradient are placed. And, it can be constructed by dividing the waterproof panel (3a, 3b) on the top of these bottom surfaces (1a, 1b).

In particular, the second bottom surface (1b) forms a gradient in one direction so that the thickness becomes thinner toward the first waterproof panel (3a) side. Accordingly, each waterproof panel (3a, 3b) can be enlarged, and the waterproof panel (3a, 3b) of the same standard can be used exclusively for the mirror generation in which adjacent generations are symmetrically arranged.

As described above, the upper surface of the bed mortar layer 2 is leveled by self-leveling of the floor mortar. Therefore, the thickness of each waterproof panel (3a, 3b) is adjusted to form a gradient of the bottom surface.

When the bathtub BT is installed on the first floor surface 1a, it is not necessary to provide a gradient to the floor surface. Therefore, the first waterproof panel 3a may use a panel having the same thickness.

The second waterproof panel 3b on the second bottom surface 1b is formed to have a thinner thickness toward the first waterproof panel 3a so that a gradient is formed toward the first waterproof panel 3a.

As in FIGS. 4 and 6 , a case in which the bathtub BT is installed in a shared bathroom will be described as an example.

In a shared bathroom having a bathtub BT, a first drain 5a may be installed on the first floor surface 1a, and water from the bathtub BT may be drained through the first drain 5a.

In addition, a trench 6 and a second drain 5b for draining water collected through the trench 6 may be installed at an end of the first bottom surface 1a on the second bottom surface 1b side. At this time, the trench 6 is mountable on the upper portion of the first waterproof panel 3a.

The water of the second bottom surface 1b can be drained to the second drain 5b through the trench 6, and accordingly, a separate drain does not need to be formed in the second bottom surface 1b.

Without forming a separate drain in the second floor surface (1b), all the water of the first and second floor surfaces (1a, 1b) is drained through the trench (6), so it is installed on the second floor surface (1b) The second waterproof panel (3b) is configured to form a gradient in one direction toward the trench (6).

In addition, it is possible to improve the workability of the formwork by applying a low-level drain to remove the step difference in the lower part of the frame floor slab (1).

Next, as shown in FIGS. 5 and 7 , a case in which the shower booth SB is installed in the couple's bathroom will be described as an example.

A first drain 5a may be installed on the first bottom surface 1a, and water from the shower booth SB may be drained through the first drain 5a.

Also in this case, a separate drain is not formed in the second bottom surface 1b.

In addition, the second waterproof panel 3b may be configured such that a gradient is formed toward the first waterproof panel 3a so as to be drained through the first drain 5a in the shower booth SB.

The first waterproof panel 3a may be manufactured to have a lower top surface than that of the second waterproof panel 3b, so that water inside the shower booth SB does not flow to the second waterproof panel 3b.

The first waterproof panel (3a) and the second waterproof panel (3b) is preferably configured to be able to respond flexibly to the bathroom area or frame manufacturing error, etc. by manufacturing the size with a margin of about 100 mm.

As described above, in the present invention, since the floor gradient can be formed by the waterproof panels 3a and 3b manufactured in the factory, it is possible to secure a certain quality without being affected by the skill level of the operator.

8 is a perspective view illustrating a first waterproof panel for a couple's bathroom, and FIG. 9 is a perspective view illustrating a first waterproof panel for a shared bathroom.

As shown in FIGS. 8, 9 and 10, the first waterproof panel 3a has a first insertion hole 34 into which a first drain 5a for a bathtub BT or a shower booth SB is inserted. is formed, and the waterproof tape 7 may be attached to the upper surface to which the upper end of the first drain 5a and the first waterproof panel 3a are joined.

A first insertion hole 34 may be formed in the first waterproof panel 3a for coupling the first drain 5a for draining water from the bathtub BT or the shower booth SB.

The present invention is to install a waterproof panel (3) having a waterproof performance by itself in a dry type, unlike the existing method in which a waterproof layer is constructed on the bathroom floor slab (1) by a wet method. Therefore, it is necessary to separately waterproof between the insertion hole and the drain of the waterproof panel (3).

To this end, after the construction of the first waterproof panel 3a, the gap of the first insertion hole 34 into which the upper end of the first drain 5a is inserted may be closed with the waterproof tape 7 .

The waterproof tape 7 is a composite material-based adhesive fire and waterproof tape used for interlayer fire protection, window sealing, waterproofing, etc., and 3M's FWBT (Fire and Water Barrier Tape) that has a high elongation and is flexible and can be easily attached to an adhesive surface. etc. can be used.

In order to secure more reliable waterproof performance, a sealant may be installed together with the waterproof tape 7 at the joint portion.

10 is a cross-sectional view illustrating a coupling relationship between a drain and a waterproof panel and an adjacent waterproof panel.

6 and 10, the second bottom surface 1b side end of the first waterproof panel 3a is provided with a trench 6 for collecting water on the second bottom surface 1b side, and , A second drain (5b) communicating with the trench (6) is provided at one end of the trench (6), and a second insertion hole (5b) into which the second drain (5b) is inserted into the first waterproof panel (3a) 35) is formed, and the waterproof tape 7 may be attached to the upper surface to which the upper end of the second drain 5b and the first waterproof panel 3a are joined.

As described above, in the case of a shared bathroom in which the bathtub (BT) is disposed, the first waterproof panel ( 3a) A trench 6 may be provided in the upper portion.

In this case, a second drain 5b may be installed to drain the water collected in the trench 6, and a second insertion hole 35 is provided in the first waterproof panel 3a so that the second drain 5b is inserted. this is formed

As in the first drain 5a, the upper portion of the second drain 5b may also be attached with a waterproof tape 7 to close the gap with the second insertion hole 35.

As shown in FIGS. 8 and 9 , the first drain 5a and the first insertion hole 34 may be formed in a rectangular shape in plan view. In addition, the second drain 5b and the second insertion hole 35 may be formed in a rectangular shape in plan view.

The waterproof tape 7 is formed in a straight band shape.

Accordingly, when the drains 5a and 5b or the insertion holes 34 and 35 are circular, the construction of the waterproof tape 7 is very cumbersome and there is a risk of deterioration of waterproof performance.

Therefore, by configuring the shape of the drains 5a and 5b and the insertion holes 34 and 35 in a rectangular shape on a plane to allow the waterproof tape 7 to be constructed in a straight line, the construction of the waterproof tape 7 can be facilitated. there is. In this case, it is also advantageous in terms of securing waterproof performance.

As shown in FIG. 10 , a flange 51 on which the first waterproof panel 3a is mounted may protrude from the upper outer side of the first drain 5a. In addition, a flange 51 on which the first waterproof panel 3a is mounted may protrude from the upper outer side of the second drain 5b.

The drains 5a and 5b are installed in advance before the floor mortar is poured, and are embedded in the bed mortar layer 2 .

When pouring the floor mortar, the level of the floor mortar is accurately set, and when the dry construction of the first waterproof panel 3a is constructed, the top surface of the first waterproof panel 3a and the top height of the drains 5a, 5b can be accurately matched. A flange 51 on which the first waterproof panel 3a is mounted may be protruded from the side surfaces of the drains 5a and 5b.

The height of the flange 51 may be set to coincide with the upper surface of the first waterproof panel 3a mounted on the upper surface of the flange 51 and the upper end of the drains 5a and 5b.

As shown in FIG. 10 , a first L-shaped step step 312 is formed at the end of one waterproof panel 3 for bonding between the adjacent waterproof panels 3 , and the end of the other waterproof panel 3 . There is an L-shaped second stepping step 313 is formed so that the first step stepping stone 312 can be installed so as to span the upper portion of the second step stepping stone 313 .

The first waterproof panel (3a) and the second waterproof panel (3b) between the bonding portion or the first waterproof panel (3a) or the second waterproof panel (3b) is divided, such as when the adjacent waterproof panel (3) bonding is required In this case, the end of the waterproof panel 3 may be processed to form steps 312 and 313 .

Accordingly, the adjacent waterproof panels 3 can be overlapped by being meshed with each other at the steps 312 and 313, so that it is possible to secure the waterproofing performance of the junction.

A silicon 8 may be provided between the first stepping step 312 and the second step stepping stone 313 .

In consideration of construction errors, etc., there is a need for clearance at the ends between adjacent waterproof panels 3 . However, in order to prevent water from penetrating into the lower part through such a gap, a silicone 8 may be constructed between the lower surface of the first stepping step 312 and the upper surface of the second step stepping step 313 ( FIG. 10 ). .

11 is a perspective view illustrating a symmetrical first waterproof panel, and FIG. 12 is a perspective view illustrating a state in which one side of the first waterproof panel shown in FIG. 11 is cut.

10 to 12, the first waterproof panel (3a) is manufactured to be wider than the first bottom surface (1a) on which the first waterproof panel (3a) is to be installed, the second insertion hole ( 35) are respectively formed at left and right positions spaced apart from each other in the first insertion hole 34, and the first waterproof panel 3a is formed on the second side opposite to the second drain 5b according to the arrangement of the second drain 5b. It can be configured to be installed on the first bottom surface (1a) by cutting the portion including the insertion hole (35).

That is, the first waterproof panel 3a may be configured as a symmetrical first waterproof panel in which the second insertion holes 35 are formed on the left and right sides of the first insertion holes 34 ( FIG. 11 ).

In FIG. 11 , the dashed-dotted line means a cuttable line.

Since the first drain 5a for the bathtub BT and the second drain 5b for the trench 6 are installed in the shared bathroom, the first waterproof panel 3a has a first insertion hole 34 and a second insertion hole. (35) is formed. However, the first insertion hole 34 is located in the middle of the width of the first waterproof panel 3a, and the second insertion hole 35 is formed to be biased to one side at a position spaced apart from one side of the first insertion hole 34 . is left and right asymmetry.

However, in the mirror household, which is usually symmetrically arranged in an apartment house, the position of the bathtub BT is also symmetrically arranged.

Accordingly, since the mirror generation has the same shape and size, the positions of the second insertion holes 35 are formed symmetrically to each other and are different. It was economical.

Therefore, the width of the first waterproof panel (3a) is slightly wider than the actual width to be installed, but the second insertion hole (35) is symmetrical to the left and right of the first insertion hole (34). By forming a pair of the first waterproof panel (3a) itself is produced so that the left-right symmetrical shape.

Then, the generation in which the second drain 5b is located on the left side of the first drain 5a cuts the right side of the first waterproof panel 3a (FIG. 12(a)), and the second drain ( 5b) The household located on the right side of the first drain 5a can be directly constructed on site by cutting the left side of the first waterproof panel 3a (FIG. 12 (b)).

The cutting of the first waterproof panel 3a can be easily performed along the dashed-dotted line shown in FIG. 11 .

When the first waterproof panel 3a is made of the same material as high-density EPS, it is easy to cut on-site in both X and Y directions.

Accordingly, the mold for manufacturing the waterproof panel 3 can be minimized, thereby reducing the manufacturing cost, and minimizing the type of material makes site management advantageous. It is easy to respond to design and field environment variability.

For example, the first floor surface (1a) side only needs to produce two types of first waterproof panel (3a) for a shared bathroom and a couple's bathroom, and the second floor surface (1b) side on which a separate drain is not installed is one type. Only the second waterproof panel (3b) of the need to be produced. Therefore, it is possible to construct all households with a total of three types of waterproof panels (3).
