Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a waterproof structure for a balcony floor provided outside a window of a general house or the like.

(Prior Art) As a conventional waterproof structure of a balcony floor, there is a structure in which a reinforcing material such as a plate material is attached on a joist material or a beam girder material, and a box body made of fiber reinforced plastic is laid on the reinforcing material. .

However, in the conventional one, since the floor surface of the balcony is formed by one plastic box body, the size of the plastic box body becomes the size of the floor surface of the balcony and the size of the box increases. Since the supporting strength of the central bottom surface tends to be insufficient, it is necessary to attach a reinforcing member such as a plate member on the joist member or the beam girder member, which is troublesome in construction and costly.

In addition, in the conventional case, the strength of the box body made of fiber reinforced plastic is weak, and the box body was made to be used alone, so it is difficult to expand the floor when constructing a large balcony etc. There was also.

(Problems to be solved by the invention) The problem to be solved by the present invention is to improve the conventional waterproof structure of the balcony floor, to make construction easy with a simple structure, low cost, durable, and wide floor surface. It is to provide a waterproof structure for the balcony floor, which is also easy to make.

(Means for Solving the Problem) The gist of the present invention which has solved the above problems is as follows: 1) A plurality of box members made of fiber reinforced plastics having stepped side surfaces of the box body and provided with horizontal shelf portions. Or, it is placed on a beam girder to form a balcony floor surface, and a connecting device having a U-shaped cross section is placed over the side surfaces of two adjacent same box bodies to connect them to each other. Waterproof structure.

2) A waterproof structure for a balcony floor according to claim 1, wherein a reinforcing member having a hollow inside is attached along the lower surface of the bottom of the box body.

3) A waterproof structure for a balcony floor according to claim 2, wherein a high-strength material having a predetermined shape is embedded inside the reinforcing material.

(Operation) According to the present invention, a plurality of box bodies made of fiber reinforced plastic are directly arranged on the joist material or the beam girder material. Then, a connecting device having a U-shaped cross section is placed over the side surfaces of the two adjacent box bodies to connect them.

In the present invention, since a plurality of boxes are combined to form the balcony floor surface, the size of one box can be reduced,
The strength of the center of the bottom of the box can be sufficiently ensured, and the strength can be increased together with the side of the box being stepped and having horizontal shelves. Therefore, it is not necessary to install a reinforcing material such as a plate material between the joists and the box, and the construction can be simplified and the cost can be reduced accordingly. Further, when a plurality of boxes are placed side by side, it is possible to cover the side surfaces of two adjacent boxes with a predetermined connecting device so that the boxes can be connected to each other. It's easy. There is no worry of water leakage because the connecting device is placed on the side surfaces of the two adjacent box bodies, and the side surfaces of the box bodies have stepwise horizontal shelves, so the gap between the side surfaces of the adjacent box bodies. Even if rainwater rises due to surface tension / capillary phenomenon, both side surfaces are separated by this horizontal shelf part, so there is no further rise in rainwater due to surface / tension / capillary phenomenon. The waterproof property is extremely good without rainwater or the like penetrating through the gap with the device. In addition, the side surface of the box is stepped to improve the strength.

In the present invention, there is also one in which a hollow reinforcing member is attached along the lower surface of the bottom of the box made of fiber reinforced plastics.
By attaching the reinforcing material, the strength will be greatly improved.

In the present invention, there is also one in which a high-strength material is embedded inside a reinforcing material attached along the bottom surface of the bottom of a fiber-reinforced plastic box. By embedding a high-strength material, the strength of the box body is further improved. As the high-strength material to be buried, wood or steel with a U-shaped cross section is often used.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

1 is a partially cutaway perspective view of the embodiment, FIG. 2 is a plan view of the same,
3 is the same perspective view, FIG. 4 is a cutaway perspective view of the same portion, FIG. 5 is a partially cutaway sectional view taken along the line BB of FIG. 3, and FIG. 6 is a sectional view taken along the line AA of FIG. is there.

In this embodiment, the box side surface (1) is stepped, and the box body (3) made of fiber reinforced plastic having the horizontal shelf-like portion (2) is placed on the joist (4), The connecting device (5) having a U-shaped cross section is placed on the side surfaces (1) of two adjacent box bodies (3) to connect them. A hollow reinforcing member (7) is attached along the lower surface of the bottom (6) of the box (3), and a high-strength material (8) having a U-shaped cross section is embedded inside the reinforcing member (7). ing. The bottom (6) of the box (3) is provided with a groove (9) and a side groove (10), and the side groove (10)
A downflow hole (11) is provided at the end of the.

In this embodiment, since it is not necessary to attach a reinforcing material such as a plate material between the joist (4) and the box (3), the work can be simplified and the cost can be reduced accordingly. Further, when a plurality of box bodies (3) are placed side by side, it is possible to cover the side surfaces (1) of two adjacent box bodies (3) with the connecting device (5) so that the box bodies (3) are connected to each other. It is also easy to make a wide floor with a property. Two adjacent boxes (3)
Since the connecting device (5) is put on the side surfaces (1) of each other, there is no fear of water leakage, and the side surface (1) of the box body (3) is provided with a step-like horizontal shelf-like portion (2). Because there is a side (1)
The waterproof property is extremely good without rainwater or the like penetrating through the gap between the connector and the connecting device (5).

Further, since the groove (9) for draining, the side groove (10) and the downflow hole (11) are provided in the bottom portion (6) of the box body (3), the drainage property is also good.

In this embodiment, since the reinforcing material (7) in which the high-strength material (8) is embedded is attached along the lower surface of the bottom (6) of the box (3), the strength of the box (3) is high. Yes, it is very durable. The step (1) of the side surface (1) of the box body (3) also contributes to the strength improvement of the box body (3). Good results were obtained when wood or a steel material having a U-shaped cross section was used as the high-strength material (8) embedded inside the reinforcing material (7).

(Effects of the Invention) According to the present invention, it is possible to provide a waterproof structure for a balcony floor, which has a simple structure, is easy to construct, is low in cost, is durable, and can easily form a wide floor surface.
