Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof construction structure for a bathroom,

The present invention relates to a waterproof construction structure for a bathroom and a waterproof construction method using the waterproof construction structure. More particularly, the present invention relates to a waterproof construction structure for a bathroom, which is not affected by weather and can be demolished without using a machine, And a waterproofing method using the same.

Waterproofing works to prevent leakage of various building structures is one of the most important construction industries for maintenance and reinforcement of concrete structures that are frequently caused by weathering, deformation and cracking over time.

Generally, epoxy resins or unsaturated polyester resins are most widely used to form coatings for imparting acid resistance and water resistance to concrete structures.

In particular, unsaturated polyester resins are used together with glass fibers, so-called FRP (Fiberglass Reinforced Plastics) resins, which are used in tank tanks where acid resistance is required. These epoxy resins and FRP resins are excellent in acid resistance and have been used in waterproofing methods to form coating films on concrete surfaces in order to protect and waterproof concrete in storage tanks.

Particularly, a coating method using the above epoxy resin is used for a reservoir, a reservoir, a drinking water tank and a bathroom. Epoxy coated film has strong film strength and low elastic elongation. Therefore, it is inappropriate to apply it to a concrete structure where cracks occur due to continuous and repeated shrinkage and expansion activities of concrete. That is, the conventional anticorrosive coating film formed of the epoxy resin has a problem that the concrete structure is shrunk, inflated and resisted against cracking, and the coating film is cracked and peeled together with cracks of the concrete structure.

A prior art related to the present invention is Korean Patent Registration No. 10-1178247 (Registered Aug. 23, 2012), which discloses a waterproof coating method of a concrete water tank using a polyurea sheet panel.

The object of the present invention is to provide a waterproof construction structure for a bathroom which can be constructed within a short period of time regardless of the weather through waterproofing using a PE sheet, a demolition time and demolition noise can be reduced when the tile is demolished, Method.

Another object of the present invention is to provide a waterproof construction structure for a bathroom which is harmless to a human body by not using an organic solvent and can solve the problem of breaking a waterproof layer due to shrinkage and expansion of a concrete due to a conventional waterproof construction of concrete, Thereby providing a construction method.

To achieve the above object, according to an embodiment of the present invention, there is provided a waterproof construction structure for a bathroom comprising: a wall constituting a bottom surface and a wall surface of a bathroom; A waterproof sheet fused together by a heat sealer in a state that two or more sheets are overlapped on a bottom surface and a wall surface of the wall; A gradient mortar in which the cement is applied on the bottom surface of the wall to which the waterproof sheet is fused; And a tile attached on the gradient mortar.

A waterproof construction structure for a bathroom and a waterproof construction method using the same according to the present invention are constructed so that at least two waterproof sheets with a PE sheet stacked thereon are not affected by the weather and the demolition time and demolition noise are reduced when the tile is demolished, The waterproof layer can be reused. In addition, since no organic solvent is used, it is harmless to the human body and the problem of breaking of the waterproof layer due to shrinkage and expansion of the concrete can be solved.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention and the manner of achieving them will become apparent with reference to the embodiments described in detail below with reference to the accompanying drawings. It should be understood, however, that the invention is not limited to the disclosed embodiments, but is capable of many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Hereinafter, a waterproof construction structure for a bathroom and a waterproof construction method using the same according to an embodiment of the present invention will be described with reference to the accompanying drawings.

1 is a cross-sectional view illustrating a waterproof construction structure for a bathroom according to an embodiment of the present invention.

Referring to FIG. 1, a waterproof construction 100 for a bathroom according to an embodiment of the present invention includes a wall 110, a waterproof sheet 120, a gradient mortar 130, and a tile 140.

The wall 110 may include a bottom surface and a wall surface of a bathroom formed of concrete. At this time, it is preferable that a drain pipe 102 is formed on the bottom surface of the wall so that water in the bathroom can be drained.

The waterproof sheet 120 may be formed of a PE sheet. By forming the waterproof sheet 120 through the PE sheet, the working process can be simplified compared to the waterproofing process in which the conventional epoxy resin is applied to the wall, and curing is not required and the construction speed is fast. In addition, the process of thermally fusing the PE sheet is not only harmless to the human body but also allows the waterproof function to continue even if cracks occur in the concrete structure.

 The waterproof sheet 120 of the waterproof construction for bathroom according to the present invention may be formed by overlapping at least two sheets of PE sheets. When two or more waterproof sheets 120 are stacked and used, not only the waterproof function but also the elongation percentage, tensile strength and abrasion resistance can be increased. On the other hand, when only one waterproof sheet 120 is used, it can be easily damaged by an external impact.

A plurality of sheets of PE sheets (not shown) were fused and melted by a hot plate heated to a temperature slightly higher than the melting temperature of the material, and then the fusion sites were sufficiently melted When the hot plate is removed, the fused materials fixed to the upper and lower jigs can be mutually pressurized and fused.

At this time, the PE sheet is preferably 1 to 3 mm thick. When the PE sheet is less than 1 mm, the waterproof sheet 120 may be easily damaged by external impact. On the other hand, if the PE sheet is larger than 3 mm, the waterproof sheet 120 may have a reduced elongation.

The gradient mortar 130 can smooth the drainage of water down to the drain pipe 102 below the bathroom entrance threshold. The wall surface is preferably formed to a thickness of 6 to 8 mm, and the bottom surface is preferably formed to a thickness of 30 mm or more. When the thickness of the bottom surface is less than 30 mm, it is difficult to effectively protect the wall 110 and the waterproof sheet 120 from impact, walking and overload.

The tile 140 may be applied after applying the adhesive onto the gradient mortar 130. [ It is preferable that the bottom surface is constructed of a non-slip type tile having a low slip and the wall surface is made of a smooth and glossy tile made of ceramic material which is easy to clean. A top coating (not shown) may be applied to the top of the tile 140 to prevent damage and slip of the tile after the tile 140 on the bottom surface is applied.

3 is a view illustrating a step of fixing a waterproof sheet in a waterproofing method for a bathroom according to an embodiment of the present invention, and FIG. 4 is a cross- FIG. 3 is a view showing a waterproof construction for a bathroom according to an embodiment of the present invention; FIG.

2 to 4, the waterproofing method for a bathroom according to an embodiment of the present invention includes a waterproof sheet fixing step S110, a heat fusion step S120, a gradient mortar construction step S130, (S140).

As shown in FIG. 3, the waterproof sheet fixing step S110 is preferably performed by fixing at least two or more waterproof sheets 120, which are superimposed on the wall 110 of a concrete material, before the waterproof sheet 120 is fused to the wall 110. At this time, it is preferable that the surface of the drain pipe 102 formed on the bottom surface of the wall 110 is also covered with the waterproof sheet 120. Therefore, after the end portions of the waterproof sheet 120 are arranged so as to overlap with each other, the waterproof sheet 120, which is overlapped by the fixing pins (not shown), is provided to prevent the waterproof sheet 120 from being separated before heat- Can be fixed.

In the thermal welding step S120, the waterproof sheet 120 may be fused to the wall body 110 by using a heat fusion machine. At this time, it is preferable that the waterproof sheet 120 is fused to the bottom surface and the wall surface of the wall body 110 as closely as possible. The waterproof sheet 120 may be manually fused to the edges of the wall 110 and the drain pipe 102 and the remaining portions may be automatically fused.

At this time, the waterproof sheet 120 may be fused after applying a butyl rubber-based adhesive to the main pipe surface and corner portions of the drain pipe 102. Accordingly, it is possible to prevent the waterproof sheet 120 from being formed in a floating structure without being uniformly welded to the corner of the drain pipe 102.

The gradient mortar construction step S130 may apply the cement between the waterproof sheet 120 and the tile 140 to construct the gradient mortar 130. [ The gradient mortar 130 not only protects the wall 110 and the waterproof sheet 120 from impact, gait and overload by constructing the cement mortar at least 30 mm on the waterproof sheet 120, The bottom surface with the pipe 102 may be formed lower than the bottom surface of the bathroom.

The tile construction step S140 may be performed by attaching the tile 140 to the upper portion of the gradient mortar 130 with an adhesive. At this time, it is preferable to install a non-slip type tile having a low slip on the bottom of the bathroom, and to install a smooth and glossy tile made of a ceramic material which is easy to clean. A top coating (not shown) may be applied to the top of the tile 140 to prevent damage and slip of the tile after the tile 140 on the bottom surface is applied.

Accordingly, the waterproof construction structure for a bathroom and the waterproof construction method using the same according to the present invention can be carried out by thermally fusing two or more PE sheets to a wall of a bathroom, and installing a gradient mortar and a tile thereon . Unlike the conventional epoxy resin coating, the waterproof sheet formed of a PE sheet is fused to a wall, so that it is not affected by the weather, and the demolition time, demolition noise, and the waterproof layer can be reused in remodeling the bathroom.

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. These changes and modifications may be made without departing from the scope of the present invention. Accordingly, the scope of the present invention should be determined by the following claims.
