本考案は排水処理槽と排水管との接続装置に関

とする。[Detailed description of the invention] The present invention relates to a connection device between a wastewater treatment tank and a drain pipe, which makes it difficult for heat to be transferred from the outside to the wastewater treatment tank via the drain pipe, etc., thereby increasing the temperature of the wastewater treatment tank. The purpose is to make it difficult for the fire to spread to adjacent floors, and to allow enough time for the fire to spread to adjacent floors.

階以上の中間階に存する場合は、床下に吊持状に
設置されるよう望む要求が強い。 A wastewater treatment tank called a gray water treatment tank or a grease trap is installed in the kitchen of restaurants, and is widely used to collect wastewater from the kitchen in one place and remove residue and oil from the wastewater. It is used. These wastewater treatment tanks are buried underground or placed on the floor when the kitchen is on the first floor of a building, but as buildings have become taller in recent years, restaurants have been installed on intermediate floors underground. Or on the ground 2
If the system is located on an intermediate floor or above, there is a strong demand for it to be installed under the floor in a hanging manner.
然し乍ら一方に於いて、これら建造物には火災
時の延焼を防止する旨の建築基準法の適用があ

合、下階の柱その他が転倒して床部分を破損する
ものでなく、しかもこれにより上階に熱が伝導さ
れないよう遮熱性及び耐強度性が考慮されなけれ
ばならない。 However, on the other hand, the Building Standards Act applies to these buildings to prevent the spread of fire, and any areas where fire may spread must be surrounded by fireproof construction. For example, if a fire breaks out on the lower floor and the temperature exceeds 1000°C, the floor above the floor must be fireproof so that it can be maintained at 260°C or less for at least two hours. In this case, heat insulation and strength must be considered so that pillars and other structures on the lower floor do not fall and damage the floor, and heat is not transferred to the upper floors.
而して床下に吊持される排水処理槽にあつて
も、これ自体が床の構成部分として、上記耐火構
造であること、遮熱性及び耐強度性を満足しなけ
ればならないと類推され、従来より上記条件を満
足するような各種の排水処理槽が提供されてい
る。 Therefore, even in the case of a wastewater treatment tank suspended below the floor, it is assumed that the tank itself, as a component of the floor, must have a fireproof structure and satisfy the heat insulation and strength resistance requirements mentioned above. Various wastewater treatment tanks are provided that more fully satisfy the above conditions.

て、排水処理槽の下階の火災時には、排水処理槽
のある階に短時間で延焼し、その延焼するまでの
時間を分に確保できなかかたのが実情である。 However, the connection between the wastewater treatment tank and the drain pipe did not have any heat shielding properties taken into account to prevent heat from being transferred from the drain pipe to the wastewater treatment tank, so a fire occurred on the floor below the wastewater treatment tank. In this case, if the heat conduction from the drainage pipe to the wastewater treatment tank is good, and the wastewater treatment tank heats up in a short time, and the wastewater treatment tank is made of FRP, the wastewater treatment tank itself may burn, or the wastewater treatment tank may burn. If the wastewater treatment tank is made of non-combustible materials such as stainless steel plates, in the event of a fire on the floor below the wastewater treatment tank, the fire will quickly spread to the floor where the wastewater treatment tank is located due to things such as burning of objects near the wastewater treatment tank. However, the reality is that there was not enough time for the fire to spread.

は極めて大となる。 According to the first embodiment configured as described above, the intervening body 11 is interposed between the flange portions 8 and 10 of the joint pipe 7 and the drain pipe 9, and this intervening body 11 serves as a heat insulating layer. Since it is made of a heat insulating material or a molten material that melts at high temperatures to form a heat insulating air layer, in the event of a fire, the waste water treatment tank 3 is removed from the drain pipe 9 via the joint pipe 7.
There is no good heat transfer to. In addition, the portion between the wastewater treatment tank 3 and the drain pipe 9, that is, the joint pipe 7, the intervening body 11, and the flange portion 10 of the drain pipe 9
is covered with a heat insulating member 17 consisting of a heat insulating material 19 and a protective pipe 18 on the outside thereof, so that in the event of a fire, good heat conduction from the outside to the wastewater treatment tank 3 via the joint pipe 7 is ensured. blocked. Therefore, in the event of a fire on the lower floor of the wastewater treatment tank 3, the drain pipe 9
Heat is not easily transmitted to the wastewater treatment tank 3 through the joint pipe 7, etc., and the temperature of the wastewater treatment tank 3 is difficult to reach. Can be secured sufficiently. Furthermore, since the heat insulating member 17 covers the part between the wastewater treatment tank 3 and the drain pipe 9 to keep it airtight from the outside, in the event of a fire, both the joint pipe 7 and the drain pipe 9 are covered. Smoke or flames may flow from the outside to the wastewater treatment tank 3 through the intervening body 11 of the flanges 8 and 10 and through the joint, or vice versa. Air will not be sucked into the lower floor from the side, and the joint pipe 7 and the like will not function as a chimney, making it possible to better prevent the spread of fire. In particular, when the intervening body 11 is formed from a molten material, the role of the heat insulating member 17 becomes extremely large.

If the joint pipe 7 is made of a heat insulating material, the joint pipe 7 itself becomes a heat insulating layer, and if the joint pipe 7 is made of a molten material, the joint pipe 7 will melt at high temperatures. As a result, an insulating air layer is formed. In this case, the flange portion 8 provided on the joint pipe 7 is formed of a refractory material such as iron, and is fixed to the outer peripheral surface of the end portion of the joint pipe 7 using an adhesive or the like. Further, the protective tube 18 has a cylindrical shape, and the end thereof on the flange portion 8 side is connected to the flange portion 8.
It is welded to the outer periphery of the surface opposite to the joint surface. Further, the end of the drain pipe 9 is also welded to the flange portion 10 while being inserted thereinto.

点を有し、実益大である。 As described in detail above, the present invention connects the drain pipe to the wastewater treatment tank via a heat insulating means, and also covers the space between the wastewater treatment tank and the drain pipe with a heat insulating member, so that the bottom of the wastewater treatment tank is In the event of a fire on a floor, it is difficult for heat to be transferred from the outside to the wastewater treatment tank via drainage pipes, etc., and the wastewater treatment tank is less likely to reach high temperatures. In addition to being able to secure a sufficient amount of time for the specified time, the above-mentioned heat insulating material covers the space between the wastewater treatment tank and the drain pipe to maintain airtightness from the outside, so in the event of a fire, the connection to the wastewater treatment tank cannot be passed through. This prevents smoke and flames from flowing from the outside into the wastewater treatment tank, or conversely, prevents air from being sucked into the lower floor from the wastewater treatment tank through the above-mentioned connection, and prevents the spread of fire. can be suitably prevented. The present invention has the above advantages and is of great practical benefit.
