【発明の属する技術分野】
本発明は配管等の防火区画貫通部施工方法に関し、詳しくは、予め、構造体に設けられた貫通孔の開口部の周囲に係止自在な環状の係止部を備えた支持具本体と、その支持具本体に係止可能で、外周部に一方向に切り起こした複数の突起部を形成してある耐火性充填材受止め部材とで、支持具を構成しておくと共に、 前記支持具本体と前記耐火性充填材受止め部材とを夫々径方向に分割して形成しておいて、前記貫通孔に長尺体を挿通して、前記支持具に耐火性充填材を保持させて前記貫通孔を耐火閉塞する防火区画貫通部施工方法に関する。
【０００２】
【従来の技術】
従来、上記防火区画貫通部施工方法においては、床スラブや防火区画壁等に空調配管や電線管等の長尺体１２を貫通させるための貫通孔１１を形成した際に、火災が発生して、前記貫通孔１１と前記長尺体１２との間の空間を通じて熱気が隣接する防火区画に流入することを防止するために、前記貫通孔１１に挿通した長尺体１２の周囲に熱膨張性パテ等の耐火性充填材１３として充填することが行われている。この耐火性充填材１３を前記貫通孔１１内に保持するために支持具１を前記貫通孔１１内に装着する。前記支持具１は、構造体１０に設けられた貫通孔１１の開口部１１ａの周囲に係止自在な環状の係止部３を備えた支持具本体２と、その支持具本体２に係止可能で、外周部に一方向に切り起こした複数の突起部７ａを形成してある耐火性充填材受止め部材７とで構成してあり、前記支持具本体２と前記耐火性充填材受止め部材７とは夫々径方向に分割して形成してある。
【０００３】
前記貫通孔１１を耐火閉塞するには、前記貫通孔１１に長尺体１２を挿通して、前記支持具１に前記耐火性充填材受止め部材７を支持させて、前記耐火性充填材１３を前記耐火性充填材受止め部材７に保持させる。前記耐火性充填材１３は、通常前記貫通孔１１内に挿通された長尺体１２の周囲と、前記貫通孔１１の入口側の前記長尺体１２の周囲とに充填され、後者の充填のために、内部に耐火性充填材収容空間を形成する蓋部材８が前記係止部３に取り付けられ、前記係止部３と前記蓋部材８との間に前記耐火性充填材１３が充填される。
【０００４】
【発明が解決しようとする課題】
ところで、上記従来の防火区画貫通部施工方法においては一般に、前記貫通孔１１の奥に前記耐火性充填材１３を受け止め自在な耐火性充填材受止め部材７を備えて、前記耐火性充填材受止め部材７を前記貫通孔１１の奥に支持自在な耐火性充填材支持部４を前記支持具本体２に設けたものが用いられる。このような耐火性充填材受止め部材７を用いて前記耐火性充填材１３により前記貫通孔１１を耐火閉塞する場合に、前記貫通孔１１内部と前記貫通孔１１の入口側とに共に前記耐火性充填材１３を充填するから、前記耐火性充填材１３の充填量が必要以上に多くなる場合があり、前記貫通孔１１の入口側のみに充填したり、前記貫通孔１１内部のみに充填したりすることが考えられる。このように、充填場所っが異なる場合には、夫々に異なる支持部材を必要とすることが考えられる。
【０００５】
そこで、本発明に係わる防火区画貫通部施工方法の目的は、部材の兼用化を図って、共通部材を使用可能にする手段を提供する点にある。

The support body 2 is formed in an annular body that can be locked around the opening 11a of the through-hole 11, and is divided into two in the radial direction and is pivotally connected to one of the divided portions. A refractory filler support 4 that includes the portion 3 and is capable of receiving the first receiving member 7A in the back of the through-hole 11. The refractory filler support 4 is connected to the connecting portion 5. The receiving member supporting portion 6 is attached to the locking portion 3 via the pin. The receiving member supporting portion 6 is also formed in an annular shape and divided into two parts, and the divided parts at both ends are formed so as to be fitted and connected to each other. The first receiving member 7A is similarly divided into two in the radial direction, and one of the divided portions is pivotally connected. This first receiving member 7A is formed by cutting up and protruding protrusions 7a that can be inserted into the through-holes 11 in one direction through the insertion holes of the locking part 3 at four equally spaced positions on the outer periphery. . The notch portion 7b is fitted into the connecting portion 5 and serves to position the first receiving member 7A. The second receiving member 7B is also divided into two in the radial direction, and one of the divided portions is pivotally connected to form a protruding portion 7a that is cut and raised in one direction at four locations on the outer peripheral portion at equal intervals. It is. The protrusion 7a is formed so as to be able to be locked to the opening 11a or the locking portion 3. On the other hand, when the second receiving member 7B is used as a refractory filler receiving member attached to a refractory filler supporting portion of another support applied to a larger-diameter through hole, the protrusion A notch 7b formed by cutting and raising 7a is configured to engage with a connecting portion of the other support.
[0014]
An example of a procedure for filling the refractory filler 13 around the elongated body 12 in the through hole 11 using the support having the above-described configuration will be described. First, the long length inserted through the through hole 11 is described. The support body 2 is assembled by surrounding the scale body 12. The locking portion 3 is swingably opened around the pivotal support portion, and the locking portion 3 is externally fitted to the elongated body 12 with the refractory filler support portion 4 side facing the through hole 11 side.
