Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a balcony floor structure which can simplify the structure and reduce construction cost by forming a balcony floor using indoor floor panels.

[0002]

2. Description of the Related Art In recent years, so-called panel construction houses in which walls, floors, etc. are formed using panels have become widespread.

On the other hand, even in a house constructed in this way,
Various floor plans are required to be constructed according to the preference of residents, location conditions, etc., and one of them is, for example, FIG.
As shown in, on one wall surface aw of a multi-storey house main body a,
There is a structure in which a low-rise accessory house b attached integrally with the house body a is projected to form a balcony c on the roof of the accessory house b.

In the floor of such a balcony c, conventionally, as shown in FIG. 5, a beam e, which is provided along a peripheral edge of an attached house b, is provided with a receiving piece e, and a concrete panel p is provided on the receiving piece e. Was formed by placing.

[0005]

However, in such a conventional one, since the weight of the concrete panel p is large, it takes a lot of time to install the concrete panel p and the construction efficiency is poor, and as shown in FIG. As shown in the figure, since the weight of the concrete panel p is carried, the structure becomes complicated, such as the need to install the receiving beam f between the beam members d, ... And the construction cost is increased.

The present invention is based on the fact that an indoor floor panel is laid between the attached roof beam along the outer edge of the attached house and the main beam material of the house body, and the floor of the balcony can be made lighter in weight. The purpose is to provide a balcony floor structure that can improve efficiency and reduce construction costs.

[0007]

SUMMARY OF THE INVENTION The present invention is formed on a roof of an accessory house which is lower than the main body of the house and which is outwardly projected to the main body of a multi-storey house and integrally attached to the wall of the main body of the house. A balcony floor structure of a floor of a balcony, which is arranged parallel to the wall surface of the house main body and along the outer edge of the accessory house, and is supported by a wall panel of the accessory house along the outer edge, and an attached roof beam made of steel; , Along the wall surface of the main body of the house, and between the attached roof beam and the main beam material of the same height, the wooden floor inside the steel frame, the indoor floor panel is laid over the attached wooden floor panel. A beam and a main beam member are placed on a side piece and bridged, and on the floor panel, a solid and lightweight heat-insulating floor material formed by using a heat-insulating material is laid and the upper surface thereof is rain-treated. There is.

[0008]

[Operation] On the roof of the attached house, between the attached roof beam parallel to the wall surface of the house and along the outer edge of the attached house, and the main beam member along the wall of the house and at the same height as the attached roof beam. Form a balcony floor by spanning indoor floor panels. In this way, since the balcony floor is constructed by using a floor panel that is lighter than the concrete panel, it is not necessary to attach a support material for supporting the balcony floor, and the structure can be simplified and the construction cost can be reduced. It is possible to reduce the cost and improve the construction efficiency.

Further, since the indoor floor panel forming the floor of the main body of the house is used for the balcony floor, it is possible to reduce the number of member types without using a new floor member dedicated to the balcony floor. A cost reduction can be achieved.

Further, a solid and lightweight heat insulating floor formed by using a heat insulating material such as polystyrene, polyethylene, or plastic foam such as polyurethane foam, glass fiber, inorganic fiber such as rock wool on the floor panel. The material is laid and the upper surface of the heat insulating floor material is rain-fed by using a synthetic resin waterproof sheet such as vinyl chloride. Therefore, the top surface of the balcony floor is conveniently subjected to finishing such as watertight treatment without increasing the weight.
