Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a floor structure such as a veranda or a balcony of a house.

[0002]

2. Description of the Related Art Conventionally, floor structures such as balconies and verandas of houses are, for example, Japanese Utility Model No. 60/32284.
As described in Japanese Patent Application Laid-Open Publication No. H11-115, there is known a deck material type floor structure in which a long deck material made of a synthetic resin is used by being connected on a joist in a width direction. This deck material type floor structure is configured by arranging a plurality of deck materials cut in accordance with the opening size of a balcony or the like. Further, the deck material used for the floor structure is laid on an aluminum balcony by printing a decorative pattern such as a wood grain pattern or a stone grain pattern on the surface of the deck material to impart a design property.

However, in the deck material type floor structure described in Japanese Utility Model Publication No. 60-32284, since the deck material body is supported by joists arranged at predetermined intervals, the rigidity is small and the composite material is easily bent. In the case of a resin-made deck material, since the sinking occurs due to the weight of the human body during walking, there is a risk that the walking feeling may be impaired and water leakage may occur during walking from the connecting portion in the width direction of the deck material. Also,
A decorative pattern such as a wood grain pattern or a stone grain pattern is printed on the surface of the deck material, but there is a fear that the printed pattern is peeled off due to abrasion to impair the aesthetic appearance.

On the other hand, for example, Japanese Patent Application Laid-Open No. 59-1226
There are also known balcony floor structures as described in JP-A-62-62 and JP-A-4-23748. This is a method using a floor material formed integrally with FRP or vacuum forming a thermoplastic synthetic resin sheet to form a waterproof pan. When a large balcony floor is formed, a plurality of panels are used. A floor pan type floor structure in which members are arranged in a longitudinal direction and connected to form a dish-shaped floor surface.

In recent years, as a floor material for covering a floor of a balcony or veranda made of concrete or the like,
Various types of floors are available depending on the surface material, such as wood bricks fitted into a frame-shaped resin mat, porcelain tiles bonded to a plate-shaped resin mat, or resin tiles molded integrally with a resin mat. Cosmetic materials have been proposed (see, for example, Japanese Utility Model Laid-Open No. 5-85929, Japanese Utility Model Laid-Open No. 6-4243, Japanese Utility Model Laid-Open No. 6-49633, and Japanese Patent Application Laid-Open No. 9-96091).

[0006]

However, in the floor pan type floor structure described in Japanese Patent Application Laid-Open No. 59-122662, the balconies of houses have various widths and frontage dimensions. It is necessary to form floor pan bodies corresponding to various dimensions of these balconies. Therefore, it is necessary to prepare molding dies corresponding to various dimensions in advance, which not only increases the capital investment but also requires a storage space for the molding dies.

Further, in a floor structure in which a unit-type floor decorative material is laid as disclosed in Japanese Utility Model Application Laid-Open No. 85929/1993 or the like, a concrete floor surface is covered with the floor decorative material to suit the preference. Although there is an advantage that the floor surface can be freely decorated and directed, and the degree of freedom in design can be improved, the concrete floor of the building frame needs to be waterproofed. In other words, in order to obtain a waterproofed concrete floor surface, a vinyl chloride waterproof sheet is attached to the floor structure of the building skeleton, or a wet construction method of applying a FRP to form a waterproof layer is adopted until the concrete structure is dried. The curing time is required, and it takes time to complete the concrete floor. Besides, the construction is complicated and the cost is high.

Further, the unit floor decorative material is provided with a drainage space between the resin floor and the concrete floor by protruding legs on the back side of the resin mat, but drainage of rainwater flowing down from the floor decorative material during a torrential rain. Is insufficient, and the back surface of the floor decorative material is easily slipped between the floor surface and the concrete floor surface, so that a displacement may occur during walking, which hinders walking sensation.

Furthermore, when unit cosmetics are laid on a balcony with handrails, the wind passing through the handrail at the end of the balcony enters the drainage space behind the unit floor cosmetics, and the entire unit floor cosmetics is completely removed. There was a risk that it would wind up and blow off.

In view of such circumstances, the present invention is easy to construct as a floor structure such as a veranda or a balcony of a house, is excellent in drainage and design, and prevents slippage and displacement between a resin mat and a base. It has no walking and has excellent walking sensation, and the effect of wind on the unit floor decorative material (turning up of the floor decorative material)
