Field of the Invention The present invention relates to waterproofing floors such as flat roofs and balconies of buildings, regardless of the area and shape of the construction site, and the height level of the construction surface and the height of the entrance sash frame. The present invention relates to a waterproof structure (so-called barrier-free structure) intended to be the same as the indoor floor height.

一般的であった。2. Description of the Related Art Conventionally, a waterproof structure of a flat roof or a balcony is constructed by using a wooden or mortar structure in a construction work to create a waterproof base with a water gradient to facilitate drainage of rainwater and prevent puddles from being generated. , And then waterproofing work. At this time, since the water gradient is generally made so that the sash side of the entrance is above the water, the more the width of the balcony, the higher the floor surface on the sash side. On the other hand, since the mounting height of the entrance sash is determined according to the waterproof floor surface height, in consideration of securing the waterproof performance, it is common that the sash comes further higher than the waterproof floor surface by 100 mm or more. .

あった。SUMMARY OF THE INVENTION When designing a barrier-free house in consideration of the elderly, the height of the sash attached to the entrance and exit of the balcony is made lower, so that there is almost no step with the indoor floor. In order to achieve this, the conventional waterproof structure cannot be used, and simply lowering the height of the sash may impair the waterproof performance of the balcony.

できない構造であった。[0004] Further, since the waterproof layer is on the uppermost layer, if an effect of preventing dew condensation is to be provided by using a heat insulating material in the base material, the waterproof layer that is almost impervious to water vapor is on the low temperature side of the outdoors. For this reason, the structure cannot prevent dew condensation inside the heat insulating material.

要があった。Further, when the rising surface of the balcony has a fireproof structure, the floor surface is slanted, so that if a general drainage material is mounted horizontally, a portion where the waterproof layer is exposed is inevitably formed. However, it was necessary to separately perform fire prevention treatment.

敷き込むことを特徴としている。According to the present invention, a waterproof layer is formed on a waterproof base without a water gradient, and a dry incombustible material with a sole on it (for example, Utility Model Registration No. 3055778).
No.) directly, or after laying down a certain thickness of insulation (called insulation with drainage grooves), which has an uneven drainage structure that facilitates drainage on the back, and then dry incombustible material. It is characterized by being laid.
【0007】こうした材料構成であるため、仕上がり床

水たまりは全く発生しない。[0007] With this material composition, the finished floor surface is horizontal, but rainwater is easily drained to the lower layer through joints and the like of the dry incombustible material, and no puddles are generated on the finished surface.

ない。[0008] Since there is a horizontal finish with no water gradient, the height of the entrance sash can be kept to a minimum, thereby making it possible to make a state in which there is almost no step with the indoor floor. Even in this case, since the waterproof layer on the floor surface is located at a position somewhat lower than the sash mounting position, even if there is heavy rainfall enough to store water, there is no concern that the waterproof layer immediately overflows to the indoor side.

Structure.

により、外周部より下層へ排水されるようにする。Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a sectional view of a balcony on the second floor. First, the waterproof layer 1 is formed on the floor surface in the balcony and the surrounding rising surface. Next, the heat insulating materials 4 with drainage grooves are laid on the floor. At this time, by leaving a gap of about 10 to 15 mm from the surrounding rising surface, the water is drained to the lower layer from the outer peripheral portion.

るため隙間をつくらないようにする。Further, a dry noncombustible material (with back feet) 2 is laid on the heat insulating material. At this time, a space of about 10 to 15 mm is also laid out from the rising surface, but the space around the lower frame of the entrance sash is always a walking surface so that no space is formed.

い。It is desirable to attach the entrance sash frame after forming the waterproof layer 1 and then attach it. In this case, in order to ensure waterproof performance, a sealing material is applied to the waterproof surface at the sash attachment position, and then the sash frame is attached. It is good to attach.

mm以上に比較してもかなり低いレベルとなる。The thickness of the heat insulating material, the thickness of the dry non-combustible material, and the height of the entrance sash frame must be set appropriately in accordance with the finished height of the indoor floor surface. It is desirable to adjust only the thickness. As an example, if the indoor floor height is 75 mm, the thickness of the heat insulating material is 50 mm, and if the thickness of the dry non-combustible material is 25 mm, the total thickness is 75 mm. Will be set to the height. This height level is 200, which is the conventional general height level.
Even when compared to mm or more, the level is considerably lower.

重要となる。FIG. 2 is a sectional view in which the drainage portion is accommodated. When the vertically drained drain 11 is used, it is important to lay the heat insulating material so that the protrusion of the heat insulating material does not come over the drain port.

る。With such a structure, rainwater first flows into the gap between the heat insulating material and the dry non-combustible material from the joint gap of the dry non-combustible material and the outer circumferential gap, and then flows down into the gap between the heat insulating material and the waterproof layer. Is drained to the outside from the drain.

By attaching the, the wall surface and the floor surface are completely covered with the non-combustible material, and a finished structure excellent in fire prevention performance is obtained. At this time, it is desirable to provide a gap of about 5 to 10 mm between the sheet metal drainage material 10 and the dry incombustible material 2 so that rainwater can easily flow down from the outer peripheral portion to the lower layer.

点がある。The mounting height of the entrance sash frame on the balcony or the like can be made the same as the floor height on the indoor side without impairing the drainage performance and the waterproof performance, so that there is no step. There are also advantages such as prevention of injuries due to stumbling of the elderly and the handicapped can enter and exit by wheelchair.
【0021】バルコニー等の床面が水平となるため、例
