Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of waterproofing a rooftop of a building, a balcony or the like, particularly around a drain of a balcony for externally insulated houses.

[0002]

2. Description of the Related Art Conventionally, around a drain of a balcony for externally insulated houses, it is common practice to cut out a heat insulating plate and attach a drain cap or a protective cover to the cutout.

[0003]

However, in the conventional method of constructing a balcony for an externally insulated house, the notch portion of the insulated plate must be enlarged, and the gap between the protective cover and the insulated plate must be completely watertight. It was difficult to do. Rainwater that entered through a small gap was absorbed by the heat insulating plate, causing a significant decrease in heat insulating performance.

An object of the present invention is to provide a completely watertight structure around the drain of a balcony for externally insulated houses by a simple construction method and to maintain a stable function for a long period of time.

[0005]

In order to achieve the above object, according to the present invention, a round drain hole is formed in a balcony insulation and waterproofing surface for external insulation of a house, and a receiving surface is provided at an intermediate portion. Attach the drain socket between the base of the balcony and the insulation and waterproofing work to the base of the residential balcony. A call pipe having a receiving surface at the top is inserted into the drainage socket, and an upper receiving surface of the call pipe is adhered to a heat-insulating and waterproofing surface, and the upper surface thereof is waterproofed. The lower end of the drainage socket is inserted into the drainage gutter to waterproof the gap.

[0006]

[Function] In recent years, it is common to attach balconies to both detached houses and apartment houses, and the emphasis has been placed on the construction method as much as possible to omit on-site construction. The construction method around the residential balcony drain of the present invention is so-called waterproofing construction in which a synthetic resin foam plate is laid and adhered to concrete, plywood, etc., which serves as a base for a residential balcony, and a waterproof sheet, a waterproof panel, etc. are laminated on the upper surface thereof. It is related to the exterior insulation of a balcony for a house.

A synthetic resin foam plate used as a heat insulating material is temporarily laid on the upper surface of a residential balcony, and a drain hole penetrating from the upper portion to the base of the balcony is formed. Thereafter, the synthetic resin foam plate is removed, and a drain socket having a receiving surface on the upper surface is fixed directly to the base of the balcony. As shown in FIG. 1, the drainage socket has a pipe at an upper portion, a receiving surface at an intermediate portion thereof, and a lower portion having a watering can shape and function. The length of the upper pipe from the receiving surface of the drainage socket is 20 to 6 mm.
The range is 0 mm.

The receiving surface in the middle of the drain socket is fixed to the base of the balcony, such as concrete or plywood, with nails or screws, and the drain socket is fixed to the base of the balcony. Paste on the substrate. The material of the drain socket is stainless steel, copper, synthetic resin or the like, and in the case of synthetic resin, vinyl chloride, ABS resin, polycarbonate, polyethylene, polypropylene and the like are preferable.

[0009] A synthetic resin foam plate used as a heat insulating material is stuck on a base of a balcony for a house, and a waterproof sheet, a waterproof panel and the like are laminated and subjected to waterproof treatment. A nominal pipe with a receiving surface at the top is inserted into the drain socket. FIG. 2 is a cross-sectional view showing this state. By providing a receiving surface on the upper portion of the nominal pipe, the gap between the nominal pipe and the waterproof construction surface can be completely watertight.

A pipe called a drainage socket is fixed by an adhesive inside the drainage socket. The material of the nominal pipe with the receiving surface at the top is stainless steel, copper, synthetic resin, etc.
In the case of a synthetic resin, vinyl chloride, ABS resin, polycarbonate, polyethylene, polypropylene and the like are preferred.

The lower end of the drain socket is inserted into a hard gutter, which is a drain pipe, and the drain socket and the drain gutter are fixed to each other with an adhesive. The drainage gutter uses a pipe made of vinyl chloride and having a diameter of about 6 cm or 9 cm.

The method of waterproofing the balcony surface of the house is not particularly limited. For example, a waterproofing method using an asphalt-based material, a waterproofing method using a sheet made of synthetic rubber or synthetic resin, and a waterproofing method using a sheet made of synthetic resin. A waterproofing method of applying or spraying the liquid material while attaching it to a reinforcing cloth or a mesh may be used.
