造に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a fire-resistant structure of a building suitable for use in buildings with three-story fittings used for condominiums, hospitals, hotels, boarding houses, etc. .
（従来の技術）
共同住宅、病院、ホテル、下宿等を用途とした三階建具
上の建築物の屋根材及び大梁は、建築基準法に基づき、
所定の耐火性能を有する耐火構造でなければならない、
この屋根の耐火構造として、従来一般的には、第４図に
示すような構造が知られている。(Conventional technology) Roofing materials and girders of buildings with three-story fittings used for condominiums, hospitals, hotels, boarding houses, etc. are
Must be of fireproof construction with specified fireproofing performance.
As a fireproof structure for this roof, a structure as shown in FIG. 4 is conventionally known.

耐火性能を確保したものであった。In this conventional structure, the roofing material 01 is made of a fire-resistant material, and the large beams 02 that support the roofing material O1 are individually covered with a fire-resistant covering material 03, thereby ensuring a predetermined fire-resistant performance for the entire roof. It was something.
ちなみに、耐火被覆材０３を大梁０２に被せるにあたっ

た。(Problems to be Solved by the Invention) However, as in the conventional fireproof structure of a roof, covering each girder 02 with a fireproof covering material 03 requires a large amount of material and is extremely difficult. There is a problem in that it is time-consuming and troublesome. Furthermore, during spraying construction, the fireproof covering material 03, such as rock wool, is likely to peel off due to contact with other objects, and when pasting, the fireproof covering material 03 is easily attached to the girder 02 without any gaps. There was a problem in that it was difficult to apply fireproof coating to all the girders 02 without any gaps.
（問題点を解決す、るための手段）

る耐火材料で形成させた手段とした。(Means for solving the problem) The present invention has been made with the aim of solving the above-mentioned problems. The parting wall material erected between the roofing material and the ceiling material is divided into an upper parting wall material that partitions the attic space and a lower parting wall material that partitions the indoor space, and the ceiling material is horizontally continuous. A large beam and a small beam are installed in the attic space between the
The ceiling material, the roof material, and the parting wall material are made of a fire-resistant material having a predetermined fire-resistant performance.

間に大梁及び小梁を配設させ、前記天井材と屋根材とを
所定の耐火性能を有する耐火材料で形成させたために、
大梁及び小梁を、天井材と屋根材とで同時に耐火被覆す
ることができる。(Function) In the fireproof structure of a building according to the present invention, the ceiling material is made continuous in the horizontal direction, the large beam and the small beam are arranged in the attic space formed between the ceiling material and the roof material, and the above-mentioned Because the ceiling material and the roof material are made of fire-resistant materials that have a specified fire-resistant performance,
Large beams and small beams can be covered with fireproofing simultaneously with ceiling material and roofing material.
また、小屋裏空間に配設されてその外からは容易に見る
ことができない大梁及び小梁には耐火を直接施さずに、
小屋裏空間の外から容易に見ることができる天井材と屋
根材とに耐火が施されているために、耐火構造の管理が
容易に行なえる。In addition, large and small beams that are installed in the attic space and cannot be easily seen from outside are not directly coated with fireproofing.
Since the ceiling material and the roof material, which can be easily seen from outside the attic space, are fire-resistant, the fire-resistant structure can be easily managed.
更に、天井材によって界壁材が上部界壁材と下部界壁材
とに分断されているために、固定の際に上部界壁材を大
梁や小梁や柱が邪魔にならない位置に位置調節すること
ができる。Furthermore, since the parting wall material is divided into the upper parting wall material and the lower parting wall material by the ceiling material, the upper parting wall material must be adjusted to a position where the main beams, small beams, and columns do not get in the way when fixing. can do.
また、界壁材が耐火材料で形成されているために、ある
室内空間において火災が発生したとしても、下部界壁材
によって火災を遮断し、この下部界壁材を隔てた室内空

いは天井材が万一破損し、小屋裏空間に火災が侵入した
としても、上部界壁材によって火災を遮断し、この上部
界壁材を隔てた小屋裏空間への火災進入も防止できる。In addition, because the parting wall material is made of fire-resistant material, even if a fire breaks out in a certain indoor space, the fire will be blocked by the lower parting wall material, and the fire will not spread to the indoor space separated by the lower parting wall material. In addition, even if the roof or ceiling material is damaged and a fire enters the attic space, the upper parting wall material will block the fire and the attic space separated by this upper parting wall material will be protected. It can also prevent fire from entering the space.

が短縮化できるという効果が得られる。(Effects of the Invention) As explained above, in the fireproof structure of a building according to the present invention, since the large beams and the small beams are covered with fireproof materials simultaneously with the roofing material and the ceiling material, Compared to coating each layer individually, the effect of reducing the amount of material and labor required can be achieved.
゛ また、小屋裏空間の外からでも容易に見ることがで
、きる天井材と屋根材とに耐火が施されているために、
耐火構造の管理も容易であるという効果が得られる。゛ In addition, it can be easily seen from outside the attic space, and since the ceiling and roof materials are fire-resistant,
The effect is that the fireproof structure can be easily managed.
更に、天井材によって界壁材が上部界壁材と下部界壁材
とに分断されているために、上部界壁材の設置箇所を大
梁や小梁や柱が邪魔にならない位置に位置調節できると
いう効果が得られる。Furthermore, since the parting wall material is divided into the upper parting wall material and the lower parting wall material by the ceiling material, the installation location of the upper parting wall material can be adjusted to a position where the large beams, small beams, and columns will not get in the way. This effect can be obtained.
また、界壁材を耐火材料で形成したために、火災が発生
しても、この界壁材によって火災を遮断して界壁材を隔
てた空間への火災の進入を防止できる。Furthermore, since the parting wall material is made of a fire-resistant material, even if a fire breaks out, the parting wall material can block the fire and prevent the fire from entering the space separated by the parting wall material.
