以下、本発明の基礎点検口用部材の実施の形態を、図面に基づいて説明する。   Hereinafter, an embodiment of a member for a basic inspection port of the present invention will be described based on the drawings.

図１〜図３に、本発明の基礎点検口用部材の第１実施例を示す。
この基礎点検口用部材１は、特許文献１〜２に記載された従来の基礎点検口用部材と同様、基礎を構築する際に基礎と一体となるように、より具体的には、布基礎を構築する際に屋内側の布基礎と一体となるように設置されるもので、外枠部２と、この外枠部２の内周に沿って形成された易破断部４を介して一体に設けられた隔壁部３とを備え、易破断部４を破断することによって、隔壁部３を外枠部２から分離し、分離した隔壁部３を外枠部２に嵌め込むことによって、外枠部２の開口で構成される点検口部の気密状態を維持するようにしたものである。 1 to 3 show a first embodiment of the member for a basic inspection port of the present invention.
The foundation access port member 1 is, like the conventional foundation access port members described in Patent Literatures 1 and 2, more specifically, the cloth foundation so as to be integrated with the foundation when constructing the foundation. To be integrated with the fabric base on the indoor side when constructing the frame, and the outer frame portion 2 and the easily breakable portion 4 formed along the inner periphery of the outer frame portion 2 are integrated The partition portion 3 is separated from the outer frame portion 2 by breaking the easily breakable portion 4, and the outer portion 2 is fitted with the separated partition portion 3. The airtight state of the inspection opening portion formed by the opening of the frame portion 2 is maintained.

この場合において、基礎点検口用部材１は、合成樹脂材料、好ましくは、断熱性及び若干の変形性を有する発泡樹脂材料を用いて一体成形することができる。
そして、易破断部４は、地震等の負荷を受けても破断しない程度の強度を備えるとともに、大きな押圧力等の負荷を受けることによって破断する薄肉部として構成するようにしている。
なお、易破断部４を破断する場合、必要に応じて、カッターやマイナスドライバを用いて易破断部４を切断するようにすることもできる。 In this case, the basic inspection port member 1 can be integrally molded using a synthetic resin material, preferably a foamed resin material having heat insulation and some deformability.
The easily breakable portion 4 has a strength that does not break even when receiving a load such as an earthquake, and is configured as a thin portion that is broken by receiving a load such as a large pressing force.
In the case where the easily breakable portion 4 is broken, the easily breakable portion 4 can also be cut using a cutter or a flathead screwdriver, if necessary.

そして、分離した隔壁部３を外枠部２に嵌め込む際に、隔壁部３の前面側と背面側とを反転させて外枠部２に嵌め込むようにすることができる。
これにより、前面側の外枠部２の内周面２１と隔壁部３の外周面３１の間の隙間４１、すなわち、易破断部に至る空間の大きさを、背面側の同隙間４２より大きく設定することができ、易破断部４の破断作業を行い易くすることができる。
なお、外枠部２の内周面２１及び隔壁部３の外周面３１の形状を、隔壁部３の前面側と背面側とを反転させずに外枠部２に嵌め込むことができる形状にすることもできる。
また、易破断部４の破断作業を行い易くするために、外枠部２の幅を、上下で異ならせている（本実施例においては、上部の幅を下部の幅より大きくなるようにしている。）。 When the separated partition 3 is fitted into the outer frame 2, the front and back sides of the partition 3 can be reversed and fitted into the outer frame 2.
Thereby, the gap 41 between the inner peripheral surface 21 of the outer frame 2 on the front side and the outer peripheral surface 31 of the partition 3, that is, the size of the space leading to the easily breakable part is larger than the same gap 42 on the rear side. It can set, and it can be made easy to do the breaking operation of the easily fractured part 4.
The shapes of the inner peripheral surface 21 of the outer frame 2 and the outer peripheral surface 31 of the partition 3 can be fitted into the outer frame 2 without reversing the front and back sides of the partition 3. You can also
Also, in order to facilitate the breaking work of the easily breakable part 4, the width of the outer frame part 2 is made different at the top and the bottom (in this embodiment, the width of the upper part is made larger than the width of the lower part) Yes).

また、外枠部２の内周面２１及び隔壁部３の外周面３１は、本実施例においては、平行面で構成するようにしているが、いずれか一方、好ましくは、両方をテーパ面で構成し、分離した隔壁部３を外枠部２に嵌め込むことによって、当該テーパ面が相手方の面に接触するようにすることができる。
このように接触面テーパ面で構成することにより、外枠部２の開口で構成される点検口部の気密状態を確実に維持するようにすることができる。また、基礎点検口用部材１の成形性も良好なものとなる。 Further, although the inner peripheral surface 21 of the outer frame portion 2 and the outer peripheral surface 31 of the partition wall 3 are configured to be parallel surfaces in this embodiment, any one, preferably both, are tapered surfaces. By fitting the separated partition 3 into the outer frame 2, the tapered surface can be brought into contact with the other surface.
By forming the contact surface taper surface in this manner, the airtight state of the inspection opening portion formed by the opening of the outer frame portion 2 can be reliably maintained. In addition, the formability of the basic check port member 1 is also good.

また、外枠部２の外周面に、打設した基礎コンクリートが入り込む凹部２２を形成するようにすることにより、基礎を構築する際に基礎点検口用部材１の外枠部２が基礎と確実に一体となるように設置することができる。   In addition, by forming the recess 22 into which the foundation concrete that has been placed enters is formed on the outer peripheral surface of the outer frame portion 2, the outer frame portion 2 of the member 1 for the foundation inspection port is sure to be a foundation when constructing the foundation. It can be installed to be integrated with the

この基礎点検口用部材１は、基礎を構築する際に基礎と一体となるように設置される基礎点検口用部材を、外枠部２と、この外枠部２の内周に沿って形成された易破断部４を介して一体に設けられた隔壁部３とを備えた単一の部材で構成することによって、取り扱い易く、布基礎を構築する際の作業性を向上することができる。
また、基礎点検口用部材１は、設置した初期状態では、外枠部２の開口で構成される点検口部が、易破断部４を介して一体に設けられた隔壁部３によって閉鎖されているため、基礎点検口用部材１の前面側と背面側の気密状態は維持されている。
そして、床下の点検作業を行う場合は、基礎点検口用部材１の易破断部４を破断し、隔壁部３を分離することによって、外枠部２の開口で構成される点検口部を形成することで、基礎点検口用部材１の背面側の床下、例えば、ユニットバス等を用いた浴室の床下での作業を行うことができるようにする。
さらに、床下の点検作業を行った後、分離した隔壁部３を外枠部２に嵌め込むこと、本実施例においては、分離した隔壁部３の前面側と背面側とを反転させて外枠部２に嵌め込むことによって、外枠部２の開口で構成される点検口部の気密状態、すなわち、基礎点検口用部材１の前面側と背面側の気密状態を維持するようにすることができる。
ここで、外枠部２の内周面２１及び隔壁部３の外周面３１のいずれか一方又は両方をテーパ面で構成した場合は、分離した隔壁部３を外枠部２に嵌め込む際に、隔壁部３の前面側と背面側とを反転させて、基礎点検口用部材１の背面側から前面側に向けて引っ張るようにすること（又は基礎点検口用部材１の前面側から背面側に向けて押圧すること）で、外枠部２に嵌め込むようにすることができる。
そして、再度床下の点検作業を行う場合は、外枠部２に嵌め込んだ隔壁部３を、基礎点検口用部材１の前面側から背面側に向けて押圧すること（又は基礎点検口用部材１の背面側から前面側に向けて引っ張るようにすること）で、隔壁部３を外枠部２と分離することによって、外枠部２の開口で構成される点検口部を形成することができる。 The base inspection port member 1 is formed along the outer frame portion 2 and the inner periphery of the outer frame portion 2 so as to be installed integrally with the foundation when constructing the base. By comprising the single member provided with the partition part 3 integrally provided via the easily breakable part 4, it is easy to handle, and the workability in constructing the cloth foundation can be improved.
Further, in the initial state in which the member 1 for basic inspection opening is installed, the inspection opening formed by the opening of the outer frame 2 is closed by the partition 3 integrally provided via the easily breakable part 4 Because of this, the airtightness of the front side and the back side of the basic inspection port member 1 is maintained.
Then, when the inspection work under the floor is performed, the easily breakable portion 4 of the member 1 for the basic inspection opening is broken, and the partition 3 is separated to form an inspection opening constituted by the opening of the outer frame 2 By doing this, it is possible to work under the floor on the back side of the member 1 for basic inspection opening, for example, under the floor of a bathroom using a unit bath or the like.
Furthermore, after the inspection work under the floor is performed, the separated partition 3 is fitted into the outer frame 2.
