〔産業上の利用分野〕
この発明は多層建築物の階層間床部に配設された床貫通
物体を覆い、熱や炎から該貫通物体及びその周縁部を保
護する耐火カバーに関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention covers a floor-penetrating object disposed between floors of a multi-story building, and protects the penetrating object and its periphery from heat and flame. This relates to fireproof covers.
鉄筋コンクリート製の建築物等の多層建築物の階層間床

和風大便器である。この和風大便器は建築物の床コンク
リートに所定の貫通孔を設け、その穴の中に嵌込まれる
ように装着されており、その下面は階下の天井に露出し
ている。A Japanese-style toilet bowl is a typical object that is attached to a through hole bored in the floor between floors of a multi-story building such as a reinforced concrete building. This Japanese style toilet has a predetermined through hole in the concrete floor of the building, is fitted into the hole, and its lower surface is exposed to the ceiling below.

ことがあった。In the above-mentioned conditions, it cannot be said that the same safety measures are taken, and in the event of a fire, the toilet bowl will be easily destroyed as it will be directly heated by the heat and flames, and the fire brigade, etc. If the toilet bowl was rapidly cooled by water spraying, etc., the damage would be even more severe, causing the floor through hole to open wide, causing the flames to blow out and spread to the upper floors.
この対策として便器の下部を覆う耐火カバーが各種考案

熱特性が劣り、下面の熱が上部に伝導するので上部露出
面の温度を法定安全温度である２６０℃以下に保持する
ことが困難であった。As a countermeasure to this problem, various fireproof covers have been devised to cover the lower part of the toilet bowl, but none of them have a structure that has the necessary heat insulation properties and is easy to install. For example, fireproof covers such as concrete, G, R, and C have excellent heat insulating properties, but are extremely heavy and have extremely poor workability during installation. In addition, although sheet metal products are light and easy to work with, they have poor insulation properties and conduct heat from the bottom surface to the top, making it difficult to maintain the temperature of the exposed top surface below 260°C, the legal safe temperature. Ta.
この発明は上記の問題点を解消するためになされたもの
で、冷却効果が大きいので安全性が高く、且つ軽量で作
業性の良い耐火カバーを提供することを目的としている
。This invention was made to solve the above-mentioned problems, and aims to provide a fireproof cover that has a large cooling effect, is highly safe, is lightweight, and has good workability.
〔問題点を解決するための手段〕
上記目的は、多層建築物の階層間床部に配設された床貫
通物体の内面に滞水層を形成するように構成したことを
特徴とする滞水層を有する耐火カバーによって達成され
る。[Means for Solving the Problems] The above object is to provide a water retention system characterized in that a water retention layer is formed on the inner surface of a floor-penetrating object disposed between floors of a multi-story building. This is achieved by a fireproof cover with a layer.
この発明における滞水層を有する耐火カバーは、保水層
内の水分が加熱されると沸騰し、しかる後に蒸発気化す
る際に多大の熱を吸収するので冷却効果が太き層。The fireproof cover having a water retention layer according to the present invention has a thick cooling effect because the water in the water retention layer boils when heated and then absorbs a large amount of heat when it evaporates and vaporizes.
このため、耐火性が向上し、新たな防火基準を満足させ
得ると共に、軽量なので扱い易く取付は作業が簡単に行
える。Therefore, the fire resistance is improved and the new fire prevention standards can be satisfied, and since it is lightweight, it is easy to handle and can be easily installed.

着されている。Embodiments of the present invention will be described below based on the drawings. FIG. 1 is a sectional view of a toilet installation device showing an embodiment of the present invention. In the figure, a fireproof cover 2 is installed through the floor 1 of the building so that its upper end surface 3 is aligned with the floor surface 4, and a Japanese-style toilet bowl 5, which is a floor-penetrating object, is installed inside the fireproof cover 2. There is.

２から該便器５内に流出するようにＳ成されている。The outer surface of the fireproof cover 2 is covered with a heat insulating material 6, and the heat insulating material 6 is fixed to the fireproof cover 2 with mounting bolts 7. Note that the exposed head of the mounting bolt 7 is covered by a fireproof cap 16. A water supply spud part 8 is provided in the front part of the fireproof cover 2, and a cleaning tank 9 is provided.
A water conduit pipe 10 is connected to the water supply pipe 10 that leads the water to the spud part 8, so when the flush valve 11 is opened, the water in the flush tank 9 passes through the water supply pipe 1° and the water supply spud part 8, and enters the water supply port 1 of the toilet bowl 5.
S is formed so that water flows from the toilet bowl 5 into the toilet bowl 5.

らの体積に比して極めて多量の水分を吸収して膨潤し、

水層１３が形成されている。Therefore, the inner surface of the fireproof cover 2 is highly water-absorbing, absorbs an extremely large amount of water compared to its own volume, and swells.
In addition, a water retaining layer 13 made of a swelling material having a property of retaining water is formed.

あるいはフィルム状の袋等に格納されておシ、耐火カバ
ー２の内面を覆うように装着され、その上部あるいは側
面に前記給水スパッド部８と連通ずる導水管１４が開口
している。The swelling material of the water retention layer 13 is in the form of particles or a plate, and is stored singly or in a film bag, etc., and is attached to cover the inner surface of the fireproof cover 2, and the water supply layer is placed on the top or side of the fireproof cover 2. A water conduit 14 communicating with the spud portion 8 is open.

た洗浄水の一部は導水管１４から滞水層１３の膨潤材に
供給される。Since the swelling material of the water retaining layer 13 does not absorb water at the time of installation, it has a small volume and is lightweight, and the installation work is easily performed. When the installation is completed and use is started, the user opens the cleaning valve 11 and a portion of the cleaning water that has flowed into the water supply spud section 8 is supplied from the water conduit 14 to the swelling material of the water retaining layer 13.

の滞水層１３の水分は使用の都度補給されるので蒸発等
によって水分が減少することはない。The swelling material supplied with moisture increases its volume while incorporating the moisture into its own composition, so that a thick water-retaining layer 13 rich in moisture is formed on the inner surface of the fireproof cover 2. Since the water in this water retaining layer 13 is replenished each time it is used, the water does not decrease due to evaporation or the like.

カバー２の上端部３が過熱することはない。In such a situation, a fire broke out and spread to the ceiling of the toilet, and the combustion continued for a long time, causing the insulation material to become damaged.
Even if insulation is not possible, an extremely large cooling effect can be obtained by boiling the water in the water retention layer 13, and the upper end 3 of the heat-resistant cover 2 will not be overheated.

している。In this embodiment, a groove 15 is provided on the inner surface of the heat-resistant cover 2, and the above-mentioned swelling material is housed in the groove 15 to form a water retaining layer 13, which is also supplied with water through a water conduit 14 each time it is used. Therefore, it has the same functions and effects as the previous embodiment.
