前記支持金具1の掛け止め部4は、充填材用受止め部3の両長辺側部分3Aの先端と短辺側部分3Bの短辺方向中央部位の三箇所に設けられている。この支持金具1の掛け止め部4は、断面倒立L字状で挿通孔B1の開口縁に係止可能で、コンクリートネジbなどを用いて躯体bに固定可能なネジ受孔4aが形成されている。   The latching portions 4 of the support fitting 1 are provided at three locations, that is, the distal ends of both long side portions 3A of the filler receiving portion 3 and the short side direction central portion of the short side portion 3B. The latching portion 4 of the support metal 1 has an inverted L-shaped cross section and can be locked to the opening edge of the insertion hole B1, and is formed with a screw receiving hole 4a that can be fixed to the housing b using a concrete screw b or the like. Yes.

各支持金具1における充填材用受止め部3の湾曲角部3Cの3箇所には、内方側に向かって開口するU字形の切込み5が形成されている。この切込み5によって、例えば、切込み5の両側の部分を挟み持って、切込み5の開口が開く方向又は閉じる方向に開閉操作することができることを利用して、適宜の切込み5の開き操作又は閉じ操作を調節することによって、挿通孔B1の短辺側内面Baと両長辺側内面Bbに沿って略コの字状に充填材用受止め部3を形態変形することができる。   U-shaped cuts 5 that open toward the inward side are formed at three portions of the curved corner portion 3C of the filler receiving portion 3 in each support fitting 1. For example, the opening 5 or the closing operation of the appropriate notch 5 can be performed by utilizing the fact that the opening 5 of the notch 5 can be opened or closed by holding the portions on both sides of the notch 5. By adjusting the length, the filler receiving portion 3 can be deformed in a substantially U-shape along the short side inner surface Ba and the long side inner surface Bb of the insertion hole B1.

このことを利用して、図12に示すように、挿通孔B1の長辺側内面Bb間の対向距離T1が、通常状態の支持金具1における充填材用受止め部3の長辺側部分3Aの外端同士の対向間隔T2よりも大きい場合、適宜の切込み5を開き操作又は閉じ操作を調節することによって、挿通孔B1の対向する長辺内側内面Bb間の距離T1に対応するように、挿通孔B1の短辺側内面Baと両長辺側内面Bbに沿って略コの字状に支持金具1の充填材用受止め部3を変形することができる。図面にいては、湾曲角部3Cの真中の切込み5を開き操作し、両端の切込み5を閉じ操作して、挿通孔B1の略直角の内隅に対応する変形させた状態を示している。また、図面では、両湾曲角部3Cの切込み5を操作する例を示しているが、この例よりも対向距離T1が小さい場合、片側の湾曲角部3Cの切込み5を操作することで挿通孔B1の略直角の内隅に対応する変形を行なうことができる。   By utilizing this fact, as shown in FIG. 12, the facing distance T1 between the long side inner surfaces Bb of the insertion holes B1 is such that the long side portion 3A of the filler receiving portion 3 in the support bracket 1 in the normal state. If it is larger than the facing interval T2 between the outer ends of the two, by adjusting the opening operation or closing operation of the appropriate notch 5, so as to correspond to the distance T1 between the long side inner surfaces Bb facing each other of the insertion hole B1. The filler receiving portion 3 of the support fitting 1 can be deformed in a substantially U shape along the short side inner surface Ba and both long side inner surfaces Bb of the insertion hole B1. In the drawing, a state in which the middle notch 5 of the curved corner portion 3C is opened and the notches 5 at both ends are closed and deformed corresponding to the substantially right inner corner of the insertion hole B1 is shown. Moreover, although the drawing shows an example in which the cut 5 of both curved corners 3C is operated, when the facing distance T1 is smaller than this example, the insertion hole is obtained by operating the cut 5 of the curved corner 3C on one side. A deformation corresponding to the substantially right inner corner of B1 can be performed.

一方、前記補助支持金具6は、前記両支持金具1の充填材用受止め部3で受止められた充填材Dを支持する水平方向に沿う受け部6Aと、該受け部6Aの一端に鉛直方向に連続する脚板部6E、該脚板部6Eの上端から水平方向に延出された挿通孔B1の開口縁に係止固定可能な掛け止め部6Bから構成されている。この補助支持金具6の掛け止め部6Bには、コンクリートネジbなどを用いて躯体に固定可能なネジ受孔6eが形成されている。   On the other hand, the auxiliary support fitting 6 has a receiving portion 6A along the horizontal direction for supporting the filler D received by the filler receiving portion 3 of the both support fittings 1 and one end of the receiving portion 6A. A leg plate portion 6E that is continuous in the direction, and a latching portion 6B that can be locked and fixed to the opening edge of the insertion hole B1 extending in the horizontal direction from the upper end of the leg plate portion 6E. A screw receiving hole 6e that can be fixed to the housing using a concrete screw b or the like is formed in the latching portion 6B of the auxiliary support fitting 6.

前記補助支持金具6の掛け止め部6Bの基端部には、図1、図2に示すように、基端に向う程、上方に位置するテーパー部6Dが一体形成され、受け部6Aに対して直角に折り曲げ形成された脚板部6Eの上端部が前記テーパー部6Dと交差して、その交差点が掛け止め部6Bよりも高くなっている交差部6Gが形成されている。   As shown in FIG. 1 and FIG. 2, a taper portion 6D located above the base end portion of the latching portion 6B of the auxiliary support fitting 6 is formed integrally with the receiving portion 6A. An upper end portion of the leg plate portion 6E bent at a right angle intersects the tapered portion 6D, and an intersection portion 6G is formed in which the intersection is higher than the latching portion 6B.

挿通孔B1の開口縁に補助支持金具6を載置状態に係止した仮止め状態にあるとき、例えば、受け部6Aに垂直荷重等の不意の外力が加わった場合、掛け止め6Bと受け部6Aとの間に交差部6Cが存在することによって、このような交差部6Gが形成されていない場合に比べて、掛け止め部6Bが挿通孔B1に滑り移動して、補助支持金具6が挿通孔B1に滑り落ちるのを抑制することができる。   When the auxiliary support metal fitting 6 is in a temporarily fixed state in which the auxiliary support metal fitting 6 is locked in the mounting state at the opening edge of the insertion hole B1, for example, when an unexpected external force such as a vertical load is applied to the receiving portion 6A, Since the crossing part 6C exists between 6A, the latching part 6B slides to the insertion hole B1 and the auxiliary support metal fitting 6 is inserted as compared with the case where such a crossing part 6G is not formed. It is possible to suppress sliding down into the hole B1.

そのため、掛け止め部6Bを開口縁にコンクリートネジbによって止着するまで安定した仮止め状態を維持することができ、挿通孔B1に対する補助支持金具6の装着性の向上を図ることができる。   Therefore, a stable temporary fixing state can be maintained until the latching portion 6B is fixed to the opening edge by the concrete screw b, and the mounting property of the auxiliary support fitting 6 to the insertion hole B1 can be improved.

前記補助支持金具6の受け部6Aには、該受け部6Aを短辺方向中間位置で長辺方向に沿って折り曲げ又は破断分離可能な脆弱部6Cが形成されている。脆弱部6Cは、長辺方向に沿って断続する複数の貫通孔6fから構成されている。   The receiving portion 6A of the auxiliary support fitting 6 is formed with a fragile portion 6C that can be bent or broken and separated along the long side direction at an intermediate position in the short side direction. The fragile portion 6C includes a plurality of through holes 6f that are intermittent along the long side direction.

この脆弱部6Cは、例えば、簡易なプレス加工等によって貫通孔6fの孔開け加工して形成され、防火用充填材Dの支持に十分で且つ人的な折り曲げ操作が可能に設定されている。   The fragile portion 6C is formed, for example, by drilling the through hole 6f by a simple press process or the like, and is set to be sufficient for supporting the fireproof filler D and capable of a human bending operation.

前記防火用充填材Dとしては、図2に示すように、架台C2の側板C2bとこれに対面する挿通孔B1の両端部における短辺側内面Baと長辺側内面Bbで囲まれた端部隙間S1に着脱自在に充填可能な大きさに形成された第1防火用充填材D1と、
この第1防火用充填材D1が挿通孔B1の両端部の端部隙間S1に充填された状態で、挿通孔B1の長辺側内面Bbと挿通体Cとの間の中間隙間S2に着脱自在に充填可能な第2防火用充填材D2と、
同じく、この第2防火用充填材D2の肉厚より肉薄で、第2防火用充填材D2の略1/3程度の長さに形成され、挿通孔B1の長辺側内面Bbと挿通体Cとの間の中間隙間S2に着脱自在な第3防火用充填材D3と、
前記第1〜第3防火用充填材D1,D2,D3と挿通体Cとの間に形成される残りの細分化された小隙間S3に、柔軟性を有する少なくとも一枚の補填用熱膨張性耐火材シートD4からなる、大きさや形態が異なる4種類を備えて構成されている。

The first fireproof filler D1 is detachably attached to an intermediate gap S2 between the long side inner surface Bb of the insertion hole B1 and the insertion body C in a state where the end gap S1 at both ends of the insertion hole B1 is filled. A second fire filler D2 that can be filled with
Similarly, the second fireproof filler D2 is thinner than the second fireproof filler D2 and is approximately 1/3 of the length of the second fireproof filler D2. The long side inner surface Bb of the insertion hole B1 and the insert C A third fire-proof filler D3 detachably attached to the intermediate gap S2 between
The remaining subdivided small gap S3 formed between the first to third fireproof fillers D1, D2, D3 and the insertion body C has at least one supplementary thermal expansion property for flexibility. It consists of four types of refractory material sheets D4 that are different in size and form.

また、防火用充填材Dである第1〜第3防火用充填材D1の充填方向の長さL3は、挿通孔B1の貫通長さと同一又は略同一の長さに形成され、充填方向と直交する長さは、挿通孔B1の短辺側内面と架台C2の側板C2bとの離隔距離L5と同一又は略同一の長さに形成されている。挿通孔B1の内面と架台C2の側板C2bとの離隔距離は、挿通孔B1の大きさが異なっても同じ距離寸法に規定されている。   The length L3 in the filling direction of the first to third fireproof fillers D1, which are the fireproof filler D, is formed to be the same as or substantially the same as the penetration length of the insertion hole B1, and is orthogonal to the filling direction. The length to be formed is the same as or substantially the same as the separation distance L5 between the inner surface on the short side of the insertion hole B1 and the side plate C2b of the gantry C2. The separation distance between the inner surface of the insertion hole B1 and the side plate C2b of the gantry C2 is defined as the same distance dimension even if the size of the insertion hole B1 is different.

この実施字形態の第1〜第3防火用充填材D1,D2,D3は、図3、図4に示すように、不燃性ブロック7の長さに対応する幅を有して長尺な熱膨張性耐火材シート8を2層状態に巻装して設け、これら不燃性ブロック7とこれに巻装された熱膨張性耐火材シート8を袋体3に収納されて構成されている。ここで、この構成に限るものではなく、第1〜第3防火用充填材D1,D2,D3として、例えば、袋体に熱膨張性耐火材を粒状にした集合体を収納する構成であっても、袋体に熱膨張性耐火材から形成されたブロック体を収納する構成であっても、熱膨張性耐火材を粒状にした集合体と熱膨張性耐火材から形成されたブロック体を混在状態で収納する構成等であってもよい。   The first to third fireproof fillers D1, D2 and D3 of this embodiment have a width corresponding to the length of the incombustible block 7 and are long heat as shown in FIGS. The inflatable refractory material sheet 8 is provided by being wound in a two-layer state, and the non-combustible block 7 and the thermally inflatable refractory material sheet 8 wound around the incombustible block 7 are accommodated in the bag 3. Here, it is not limited to this configuration, and as the first to third fireproof fillers D1, D2, D3, for example, it is a configuration that houses an aggregate of thermally expandable refractory material in a bag body. Even if the bag body is configured to store a block body made of a heat-expandable refractory material, an aggregate of heat-expandable refractory material and a block body made of a heat-expandable refractory material are mixed. The structure etc. which accommodate in a state may be sufficient.

このような構成によれば、図2、図3、図6に示すように、挿通孔B1の両端部に開口側から支持金具1の充填材用受止め部3を差し入れて掛け止め部4を挿通孔B1の開口縁に係止した後、掛け止め部4のネジ受孔4aを通してコンクリートネジbを開口縁に螺入して固定して、挿通孔B1の両端部に合わせて一対の支持金具1を装着する。   According to such a configuration, as shown in FIGS. 2, 3, and 6, the stoppers 4 are inserted by inserting the filler receiving portions 3 of the support fitting 1 into the both ends of the insertion hole B <b> 1 from the opening side. After locking to the opening edge of the insertion hole B1, a concrete screw b is screwed into the opening edge and fixed through the screw receiving hole 4a of the latching portion 4, and a pair of support fittings are fitted to both ends of the insertion hole B1.
