Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention prevents the swelling of the waterproof surface by evaporating water and expanding the air contained in the synthetic resin foam plate used for the heat insulating material in the waterproof construction method which is used for the balcony of the house and has excellent heat insulation and waterproofing properties. The purpose is to prevent water from entering from the edge of the degassing sheet.

[0002]

[Prior art]

 Conventionally, a method of using a synthetic resin foam board as a heat insulating material on a balcony for a house is a floating construction method in which a heat insulating material is laid. In such a construction method, it is necessary to dry the groundwork, but the groundwork is often not fully dried, and it is often waterproofed due to evaporation after construction and thermal expansion of the air contained in the synthetic resin foam board. Blisters may occur on the surface. In addition, when the adhesive type is used, the residue of the adhesive may volatilize with the rise of temperature and cause swelling on the waterproof surface.

Such swelling not only significantly impairs the appearance of the waterproof construction surface, but also deteriorates the waterproof function. In order to solve such problems, a conventional degassing tower with the same cylindrical shape is partially installed on the waterproof surface, or a disk-shaped deaeration board is installed for deaeration. There is a method of inserting a breathable degassing sheet over the entire surface to degas from the end of the waterproof sheet, or to use this together with a degassing board.

[0004]

[Problems to be solved by the device]

 However, providing a degassing tower on a waterproof balcony for a house is not suitable as a walking obstacle when using the balcony, and its function cannot be fulfilled due to clogging by foreign matter. Since the deaeration board has a disk-shaped upper lid with a thickness of about 10 mm, it must be functionally fixed and subjected to watertight treatment, which has many problems in durability and weather resistance.

In addition, the conventional degassing sheet is a synthetic resin or rubber-based sheet having a large number of minute ventilation holes, and is constructed by laying a waterproof sheet on a waterproof base surface. Since the ventilation holes formed in the air sheet do not close, partial adhesion must be done, and rainwater may invade from the outside of the degassing sheet, which is rather difficult for construction. It was

[0006]

[Means for Solving the Problems]

 The present invention has been made to solve the conventional drawbacks, and when performing a waterproofing method for a residential balcony, a synthetic resin degassing sheet having a hollow hole with a thickness of 1 mm or more is provided on the entire or entire circumference of the residential balcony. Or, it may be adhered to different parts, bend the edge of the degassing sheet, and fix the end of the degassing sheet to the rising edge of the peripheral edge of the balcony of the house. It is a waterproof cap that can be covered with a slip prevention slit inside. When attaching the deaeration sheet to the entire surface, make slits on the surface and make a cut so that air can enter. It is possible to completely prevent rainwater from entering with the waterproof cap that covers the tip of the degassing sheet that is fixed to the rising part.

A synthetic resin foam plate and a waterproof sheet are laminated and adhered on top of a deaeration sheet, and a non-combustible waterproof coating layer is formed on the upper and lower surfaces of the non-combustible plate material and six end faces. The waterproof plates are laminated and attached, and the joint material of the waterproof plate bonding city is filled with the sealing material. The waterproof effect is further improved by applying the same non-combustible waterproof coating material applied on the entire surface of the non-combustible inorganic waterproof board to the upper surface of the sealing material and the periphery of the non-combustible inorganic waterproof board.

[0008]

[Action]

 At present, a balcony is indispensable in a detached house or an apartment house, and a waterproof method is desired to be a dry method that minimizes the site work. The waterproof cap in the present invention has been made in response to such a request, and a synthetic resin foam plate is adhered to the concrete surface or the plywood base surface of the balcony structure of the house, and the waterproof sheet is laminated on it. A non-combustible inorganic waterproof plate with a non-combustible waterproof coating layer formed by applying non-combustible waterproof coating material on the front and back surfaces of the non-combustible plate material and the six end surfaces is stacked, and the joint of the non-combustible inorganic waterproof plate is filled with a sealing material. Apply the non-combustible waterproof coating on the upper surface of the sealing material and the peripheral edge of the joint of the non-combustible inorganic waterproof board.

In such a house balcony waterproofing method, the degassing sheet is made of synthetic resin having a hollow hole with a thickness of 1 mm or more. The reason why the thickness is 1 mm or more is that a hollow hole which is too small cannot exhibit a sufficient function due to clogging or the like. However, if the hollow holes are made too large, water may flow in from the outside, so the size of the hollow holes is preferably 1 mm to 3 mm.

When the size of the residential balcony is small, it is sufficient to partially use the deaeration sheet having a width of 10 to 50 cm, but when the area is large, the entire circumference of the residential balcony or 2 It is used for half circumference or 3 surfaces. Further, depending on the construction conditions, it may be laid and stuck on the entire surface. When it is used on the entire surface of a residential balcony, a ventilation hole is formed by making a slit in the upper surface of the synthetic resin degassing sheet with a hollow hole.

The material of the synthetic resin degassing sheet having hollow holes is not particularly limited, but polypropylene, polyethylene, vinyl chloride or the like is preferable. In addition, the degassing sheet must be one that does not collapse the hollow holes when it is bent because the end is bent and fixed to the rising part of the residential balcony.

The waterproof cap that covers the tip of the deaeration sheet fixed to the rising portion is made of metal or synthetic resin, and has an anti-slip slit formed inside. When the waterproof cap is made of metal, aluminum, stainless steel, copper or the like is preferable, and when it is made of synthetic resin, acrylic, polycarbonate, polypropylene, polyethylene, vinyl chloride or the like is preferable.

As shown in FIGS. 6 and 7, the waterproof cap is placed on the tip of the degassing sheet to completely prevent water from seeping through the hollow hole at the tip, and must not be easily dropped off. It has a shape that allows the degassing sheet to be sandwiched from both sides by the force of the spring. The waterproof cap shown in Fig. 6 is flat on one side, and by using this flat surface as the fixing surface at the rising edge of the balcony, the degassing sheet can be fixed vertically. FIG. 8 shows a state in which a waterproof cap is put on the tip of the deaeration sheet. It is not necessary to use an adhesive when covering the waterproof cap, but the adhesive may be applied to the sandwiched portion of the waterproof cap and covered.

The inorganic board material used in the present invention is slag gypsum board, calcium silicate board, gypsum board, flexible board, asbestos cement perlite board, pulp cement board, ALC, PC board, block, ceramic board, GRC panel, Extruded cement boards are used. Although the size of the rectangular inorganic plate is not particularly limited, it may be any size that is easy to handle and install, and it is preferable that the vertical and horizontal dimensions are about 400 to 1000 mm and the thickness is 6 to 30 mm.

The waterproof coating layer formed on the six sides of the inorganic flat plate is a waterproof layer using an asphalt-based material, a waterproof layer using a synthetic rubber or synthetic resin sheet, and a synthetic resin liquid material is a reinforcing cloth and mesh. It may be a waterproof layer formed by applying or spraying while sticking. However, it must be a finish coating material for buildings as a fireproof material based on the Building Standards Law, and must be a non-combustible waterproof material equivalent to the base material certified by the Ministry of Construction. The non-combustible inorganic waterproof plate can be formed by applying the non-combustible waterproof material equivalent to the base material to the 6 surfaces of the non-combustible inorganic flat plate.

The sheet waterproof material attached to the plastic foam plate material is a synthetic fiber non-woven fabric, and in the present invention, a butyl rubber type, a vinyl chloride resin type, an E.I. V. A type, rubber asphalt type, E.I. P. Any of T-butyl rubber type and nylon type can be used.

Adhesive for sticking a synthetic resin degassing sheet with hollow holes to a balcony of a residential building and plastic foam board material and sheet waterproof material and adhesive used for sheet waterproof material and noncombustible inorganic waterproof board have elasticity Epoxy modified rubber type latex type, rubber type latex type, vinyl acetate resin type emulsion type, vinyl copolymer type emulsion type and the like can be used. Epoxy-modified rubber-based latex type is preferable.

The synthetic resin foam plate may be of any plastic type as long as it can be extruded or bead-molded, but polystyrene, vinyl chloride, polyurethane, phenol, polyisocyanurate and the like are preferable. The thickness of the synthetic resin plate is in the range of 10 to 50 mm, more preferably 15 to 40 mm.

The sealing material that seals the joints between the non-combustible inorganic waterproof boards having the waterproof coating formed on the six surfaces is a silicone-based sealing material 1-component type or / and 2-component type, a modified silicone-based sealing material 1-component type or A two-component type and / or a modified silicone-based sealing material two-component type are preferable. More preferably, it is a two-component type of modified silicone sealing material.

When the joint portion of the non-combustible inorganic waterproof board is filled with a sealing material and the waterproof coating layer is formed on the upper surface and the periphery of the joint portion of the non-combustible inorganic waterproof board, the waterproof coating layer is applied to the front and back surfaces and end surfaces of the inorganic flat plate. A non-combustible waterproof material equivalent to the base material is desirable.
