Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a balcony deck suitable for an outdoor terrace of a building, particularly an outdoor terrace that requires waterproofness and fire resistance in a wooden house.
[0002]
[Prior art]
In general, in a balcony provided in a detached house, the lower space is often effectively used as a living room, and the balcony itself is also exposed to wind and rain, so naturally waterproof performance is required. On the other hand, noncombustible performance may be required for balconies due to various regulations related to buildings, and in particular for wooden buildings, fire prevention measures must be taken so that they have the fire resistance specified by the Cabinet Order. .
[0003]
Conventionally, in wood-based balconies, for example, a waterproof sheet or the like is laid on the top surface of the balcony housing to perform waterproofing, and then mortar is placed on the top or a mortar mixed with a waterproofing agent is directly placed on the housing. To ensure waterproof and fireproof performance. Further, instead of mortar placement, a method of providing fire resistance by stretching a plurality of porcelain tiles is also performed.
[0004]
[Problems to be solved by the invention]
However, the above-described method for placing mortar requires time for placing the mortar, and requires a skilled installer. Also, in the inspection and repair, there was a problem that the mortar had to be broken once and cost and labor were required.
[0005]
On the other hand, if tiles are used for the surface finish, it becomes a balcony with an inorganic and cold feeling. In consideration of seeking a place of relaxation on the balcony or being used as a place of hobby such as plant cultivation, finishing with a warmer wooden material may be preferred. In addition, in the case of a wood-based house, it may be more preferable to perform surface finishing with a wood-based finishing material that can prepare materials and enhance assimilation inside and outside.
[0006]
The present invention has been made in view of the above points, and the object of the present invention is to provide waterproofing and fire resistance, which is easy for construction and maintenance work, and can shorten the construction period. To provide a balcony deck. In addition, it is to provide a balcony deck that can use a warm wooden deck material as a finishing material.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the balcony deck according to the present invention has a plurality of joists made of non-combustible material arranged in parallel on a waterproof layer provided on the floor surface, and covers the waterproof layer between these joists. A non-combustible plate is interposed, and a deck material is laid on the joists.
[0008]
According to this invention, both the non-combustible plate and the deck material can be fixed by the joists. In addition, the deck material can be made of wood, or plastic or plastic containing wood flour. By using a deck material of such a material, non-combustible material is produced by the joists and non-combustible plates made of non-combustible material. While ensuring performance, it is possible to create the required warm impression. Further, when performing maintenance work of the waterproof layer, it is easy to remove the non-combustible plate and the deck material. In addition, as joists, metals, such as iron and aluminum, are suitable, for example. Examples of non-combustible plates include cement plates and calcium silicate plates.
[0009]
In addition, a cushioning material may be provided between the waterproof layer and the joists.
[0010]
In this case, the waterproof layer is not damaged by joists, and there is no possibility that the waterproof performance of the waterproof layer is impaired.
[0011]
Further, the joist may be provided with a pedestal portion on the side surface, and the end of the non-combustible plate may be fixed to the pedestal portion.
[0012]
In this case, the attachment work of the non-combustible plate to the joists becomes extremely easy, and an air layer is formed between the waterproof layer and the non-combustible plate and between the non-combustible plate and the deck material. The drying of each member is promoted, and the occurrence of mold and corrosion is prevented.
[0013]
In order to achieve the above object, the balcony deck according to the present invention has a plurality of non-combustible plates having a bulging portion laid on the entire upper surface of the waterproof layer provided on the floor surface. It may be characterized in that a deck material is placed and laid on the part.
[0014]
In this case, since the bulging portion provided on the incombustible plate serves as a joist, it is not necessary to prepare a joist separately from the above, and the workability is further improved accordingly. As the incombustible plate, for example, a metal plate such as an iron plate is suitable.
[0015]
In addition, the bulging portion is provided on the side edge portion of the non-combustible plate, and is formed in a form that can be overlapped with the bulging portion of another adjacent non-combustible plate. You may make it connect boards. The shape of the bulging portion is preferably a ridge for ease of molding, but is not limited thereto, and may be, for example, a truncated cone shape or a truncated pyramid shape.
[0016]
In this case, the installation of the non-combustible plate only needs to overlap the bulging portions and connect them to each other, so that the workability is further improved. Furthermore, since an air layer is formed between the non-combustible plate and the deck material, drying of each member is promoted, and generation of mold and corrosion is prevented.
[0017]
In this case as well, a buffer material may be provided between the waterproof layer and the non-combustible plate.
[0018]
In this case, the waterproof layer is hardly damaged, and there is no possibility that the waterproof performance is impaired.
[0019]
In any of the types described above, various types of plastic pans including glass fiber reinforced plastics or various types of waterproof sheets can be employed as the waterproof layer. Examples of the buffer material include rubber and foamed plastic.
