Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof sheet installation structure.

[0002]

2. Description of the Related Art For example, in a residential building, at a person entrance / exit opening provided between a balcony and an indoor area, a wall under the opening is slightly raised so that water from the balcony does not flow into the indoor area. The tarpaulin from the floor of the balcony has been set up along this wall.

[0003]

However, as described above, if the wall under the opening is raised high for waterproofing, this wall protrudes above the indoor floor surface, There is a risk of getting caught in the wall below the opening when going out from the room to the balcony due to the large step.

On the other hand, if the wall under the opening is made low, the rise of the waterproof sheet becomes low on the side of the floor of the balcony, which makes it difficult to secure the waterproof performance.

In view of the above problems, the present invention provides a waterproof sheet installation structure capable of reducing or eliminating a step difference in a person entrance / exit opening, and yet ensuring sufficient waterproof performance. The task is to do.

[0006]

[Means for Solving the Problems] The above-mentioned problem is characterized in that the waterproof sheet from the floor is erected so as to extend upward on the lower surface side of the fitting lower frame of the entrance / exit for passengers. Solved by the installation structure of.

In this structure, since the waterproof sheet from the floor is erected so as to extend upward on the lower surface side of the fitting bottom frame of the entrance / exit for passengers, the height of the wall below the opening is lowered. Or, you can get rid of this wall,
As a result, it is possible to reduce or eliminate the step difference in the person entrance opening.

In addition, since the waterproof sheet from the floor is thus erected so as to extend upward on the lower surface side of the fitting bottom frame of the entrance / exit for passengers, the waterproof sheet is erected high at the opening. It is possible to secure sufficient waterproof performance.

If the waterproof sheet is divided into a floor-side waterproof sheet and a rising-side waterproof sheet, and these waterproof sheets are joined in a sealed state, the floor-side waterproof sheet must be installed on the rising-side side. It is possible to easily perform the construction of the waterproof sheet on the floor side separately from the construction of the waterproof sheet, and to separate the construction of the waterproof sheet on the rising side from the construction of the waterproof sheet on the floor side to construct the waterproof sheet on the rising side. It can be done easily.

When the floor is a floor of a balcony and the opening is a person entrance / exit opening provided between the indoor and the balcony, a step in the person entrance / exit opening between the balcony and the room Can be reduced or eliminated, and the waterproof performance on the balcony can be sufficiently ensured.

Further, when the floor is a terrace floor and the opening is a person entrance / exit opening provided between the indoor and the terrace, the person entrance / exit opening between the terrace and the indoor It is possible to reduce or eliminate the level difference in the area, and moreover, it is possible to sufficiently secure the waterproof performance on the terrace.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings.

The waterproof sheet installation structure shown in FIGS. 1 and 2 is for use on a balcony, where 1 is a balcony floor, 2 is an indoor floor, and 3 is a person entrance / exit opening provided therebetween. It is a department. Further, 4 is a fitting lower frame such as a sash frame, and 5 is a waterproof sheet.

Reference numeral 6 is a lower frame of the panel frame of the outer wall panel, 7 is a receiving member for the opening 3, 8 is a body difference, 9 is a fitting made of a sash or the like, 10 is a cantilever beam of a balcony,
Reference numerals 11 and 12 are lightweight concrete plates.

The waterproof sheet 5, which is made of a resin sheet or the like, is laid on the floor 1 of the balcony, and a range 5a from the floor 1 to the lower edge of the joiner lower frame 4 on the balcony side is raised, and further from there. , Is horizontally extended to the lower surface side of the fittings lower frame 4 by a fixed range 5b, and is raised to a higher place on the lower surface side of the fittings lower frame 4 by a fixed range 5c, and then the fitting lower frame 4 The lower surface is horizontally extended by a certain range 5d toward the indoor side, and from there, it is raised by a certain range 5e to a high place on the lower surface side of the fitting lower frame 4.

The waterproof sheet 5 is divided into a floor-side waterproof sheet 13 laid on the floor 1 side of the balcony and a rising-side waterproof sheet 14 in order to facilitate the construction. , These sheets 13, 1
Four of them are piled up on the side of the floor 1 of the balcony and joined 15 in a sealed state by heat welding or the like.

The construction of the waterproof sheet 14 on the rising side is performed before the construction of the fitting lower frame 4 in the opening 3, and the fitting lower frame 4 is installed on the constructed waterproof sheet 14 on the rising side. Good. This may be done in advance at the factory or on site.

FIG. 3 and FIG. 4 show the installation structure of the waterproof sheet 5 near the opening 3. The waterproof sheet 13 on the floor 1 side is cut at a portion corresponding to the opening 3 so as not to stand up. This notch 1 as well as being cut off
On both sides of 3a, rising portions 13b and 13b that are raised on the walls on both sides of the opening 3 are provided. Also,
The rising side includes the above-described rising side waterproof sheet 14 that stands up on the lower surface side of the fitting bottom frame 4 in the opening 3.
Rising side waterproof sheet 16, 1 for the wall beside the opening 3
It is divided into 6 and 6. And these waterproof sheets 1
As shown in FIG. 4, both side edges of the rising side waterproof sheet 14 rising under the fitting lower frame 4 are the side edges of the left and right wall side rising waterproof sheets 16, 16, as shown in FIG. The floor-side waterproof sheet 13 is overlaid, and the floor-side waterproof sheet 13 is overlaid on the lower edge portions of the rising-side waterproof sheets 14, 16, 16 and the overlapping portions are joined in a sealed state 15 by heat welding or the like to form a waterproof state. It is designed to be done.

According to the above-mentioned waterproof sheet installation structure, since the waterproof sheet 5 on the floor 1 of the balcony is erected so as to extend upward on the lower surface side of the fitting lower frame 4 of the passenger entrance / exit opening 3, The height of the wall below the opening 3 can be reduced or even eliminated, which can reduce or eliminate the step in the entry / exit opening for entrance / exit between the balcony and the room. Can be done safely.

In addition, since the waterproof sheet 5 on the balcony floor 1 is thus erected so as to extend upward on the lower surface side of the fitting lower frame 4 of the entrance / exit opening 3 for passengers, the waterproof sheet 5 is opened. It is possible to stand up high in the section 3, and it is possible to sufficiently secure the waterproof performance of the floor 1 of the balcony.

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, although the above embodiment shows the case where the invention is applied to a balcony, it can also be applied to a terrace, and there is no particular limitation on the application target, that is, the point is that it is adjacent to a floor that requires waterproofing. The present invention can be widely applied to various places where an opening for entering and exiting people is provided. Further, in the above embodiment,
Although the case where a resin sheet is used as the waterproof sheet 5 is shown, the material is not limited, and may be a metal sheet or a composite sheet of metal and resin. When the waterproof sheet 5 is divided, The material of the divided waterproof sheets may be different. Further, the floor-side waterproof sheet and the rising-side waterproof sheet may be joined by a method other than heat welding. In short, both sheets are joined by a joining method capable of joining them in a sealed state. Anything will do.
