Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing a floor surface exposed to rainwater, such as a rooftop, an outer corridor or a floor surface in a room, and a rising portion thereof.

BACKGROUND ART Conventionally, in order to waterproof a roof surface, an outer corridor, a toilet, a kitchen, etc., which is exposed to rainwater and its rising portion, the end portion of a floor waterproof sheet is lifted in an L shape and the periphery of the lifted portion is raised. A method of bonding with an adhesive has been adopted.

However, since the floor waterproof sheet usually has a thickness of about 2 mm or more in order to withstand walking of a person, the work of bending this end into an L-shape and adhering it takes a lot of labor and time and is finished. Is not clean, and further, due to the difficulty of workability, incompletely adhered parts are generated,
It was the cause of water leakage.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention aims to improve the workability of the prior art and to realize complete waterproofing.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention according to claim 1 provides a floor surface exposed to water such as a rooftop or an outer corridor and a rising portion thereof. In the waterproofing method for waterproofing the building material member, a thin waterproof sheet of about 1 mm or less is attached to the building material member of the rising part in an L-shape, and the rising part of the thin waterproof sheet is glued to the rising part of the building material member. The floor is provided with a floor waterproof sheet on the thin waterproof sheet, and the thin waterproof sheet and the floor waterproof sheet are bonded by heat welding or an adhesive. And the invention according to claim 2 is a rooftop,
In a waterproofing method for waterproofing a floor surface exposed to water such as an outer corridor and the building material members at the rising portion thereof, a thin waterproof sheet of about 1 mm or less is attached to the building material member at the rising portion in an L shape, Adhere the rising part of the waterproof sheet to the rising part of the building material member with an adhesive, and install the floor waterproof sheet on the thin waterproof sheet for the floor surface, and heat the thin waterproof sheet and the floor waterproof sheet. It is characterized in that it is welded or bonded with an adhesive, and that a skirting board is attached so as to cover the rising portion of the thin waterproof sheet which is not covered with the floor waterproof sheet, and The invention described in the third range is a waterproof method for waterproofing a floor surface exposed to water such as a rooftop or an outer corridor and a building material member at the rising portion thereof, and a thin waterproof sheet of about 1 mm or less is formed into an L-shape. Building material member of the rising portion Attached, the rising part of the thin waterproof sheet is adhered to the rising part of the building material member with an adhesive, and the floor surface is provided with the waterproof sheet for the floor surface on the thin waterproof sheet, and the waterproof sheet for the thin waterproof sheet and the floor surface. It is characterized in that the sheet is adhered to the sheet by heat welding or an adhesive, and the top of the rising portion of the thin waterproof sheet and / or the end of the floor waterproof sheet is sealed with a sealing material.

The thin waterproof sheet of the present invention is made of a thin synthetic resin or rubber having a thickness of about 1 mm or less, particularly about 0.5 mm, but in the form of a laminate having fibers on the middle or back surface. Is preferably used. The fibers may be embedded in a random manner, or may be selected and used depending on the situation such as a non-woven fabric, a woven fabric, or a mesh. As the material of the fibers, mineral fibers such as glass fibers, natural fibers, synthetic fibers and the like can be used. As the synthetic resin or rubber that constitutes the thin waterproof sheet, all known materials used for floor waterproof sheets can be used, but the materials that make up the floor waterproof sheet and the thin waterproof sheet are both heat-welded. It is advisable to use a combination of what can and what has good adhesion. In that sense, polyvinyl chloride is one of the preferred synthetic resins.

The adhesive may be applied to a thin waterproof sheet or a floor waterproof sheet by undercoating in advance, or may be applied separately during construction.

As the adhesive to be used, it is preferable to use a curing type adhesive in order to obtain a stable waterproof effect. Examples of these adhesives include epoxy-based, acrylic-based, and urethane-based adhesives.

As the sealing agent, conventionally known sealing materials can be appropriately used according to the thin prevention sheet and the floor waterproof sheet.

The thin tarpaulin is about 5 each from the boundary between the wall and the floor.
It is sufficient to use on the order of ~ 10 cm.

When the present invention is applied to the defective portion or the cut portion at the entrance / exit corner, the thin waterproof sheet can be used as an auxiliary sheet to supplement the nonexistent portion of the thin waterproof sheet at the corner portion. An example of that mode is shown in FIG. The form of the auxiliary sheet 1'is not limited to this.

Effect The present invention skillfully uses the thin waterproof sheet, whereby workability is significantly improved as compared with the conventional method,
The finish was improved, and on top of that, it was able to demonstrate complete waterproofness.
