パイプ等の長尺体を貫通させる貫通孔を防火材料で閉塞
する場合に好適な防火措置構造の提供に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention is a fire prevention measure suitable for blocking a through hole through which a long body such as an electric wire, cable, or pipe passes through a floor or wall with a fire prevention material. Regarding providing structure.

よる密閉基がなされていた。BACKGROUND OF THE INVENTION Conventionally, as an improvement on the method of bolting a fire-resistant partition plate such as a calcium silicate plate to a floor forming a through-hole, which is used to close the opening of a through-hole, there is a method using a support fitting. This is used in floor through-holes, where it is shaped into a Z-shape, one bent end is hooked onto the floor surface, and the other bent end is hung inside the through-hole. A fire-resistant partition plate such as a calcium silicate plate is placed on the bent end to close the bottom of the through-hole, and a fire-retardant material is filled in the through-hole with the fire-resistant partition plate at the bottom. However, the through holes were sealed with fireproof material.
（実公昭５８−１６７７１号公報参照。）〔発明が解決
しようとする課題〕
かかる支持金具によるものは、耐火性仕切り板の固定作
業が省力化される利点があるものの、次のような問題が
あった。(Refer to Japanese Utility Model Publication No. 58-16771.) [Problems to be Solved by the Invention] Although such a support metal fitting has the advantage of saving labor in fixing the fire-resistant partition plate, it has the following problems. there were.

要としていた。The fire-resistant partition plate is simply dropped into the through-hole from the upper opening and placed on the lower bent end of the vertically installed support metal fittings, so the support metal fittings cannot be latched while the fire-resistant partition plate is pushed in. In order to maintain the condition, it is necessary to temporarily fix the metal fittings, and it is necessary to take additional troublesome measures such as embedding insert nuts for screwing bolts into the floor surface.

ったりして正しく入らないことが多く、−旦貫通孔内に
落ち込んだ当該耐火性仕切り板を正規の姿勢に修正する
作業は困難であり、装填し直さざるを得なかった。In addition, since fire-resistant partition plates are installed around a long object that has already passed vertically through the through-holes, they are usually divided into two parts, but if multiple fire-resistant partition plates like this are installed from above the floor, When dropped into a hole, it often gets caught on the inner surface of the through hole and does not go in correctly. I had no choice but to do it again.
そして、分割された耐火性仕切り板の落とし方によって
は、該耐火性仕切り板が、貫通孔から脱落して落下する
可能性があり、もし下側階に作業者がいた場合には危険
が伴うこともあった。Depending on how the divided fire-resistant partition plates are dropped, there is a possibility that the fire-resistant partition plates may fall off from the through-holes and fall, which is dangerous if there is a worker on the lower floor. Sometimes it happened.

ともに貫通孔内に装填することにより、耐火性仕切り板

しに所定の位置まで挿入することができる。According to the fire prevention structure of the present invention, the fire-resistant partition plate can be clamped from the top, bottom, left and right by the plurality of supporting metal fittings, so the fire-resistant partition plate can be loaded into the through-hole together with the supporting metal fittings in the same state. As a result, the fireproof partition plate can be inserted into the through hole without falling off from the support fitting until it reaches a predetermined position.

可能になる。In addition, the loaded fireproof partition plate is restrained from moving from the inside and outside by the holding piece and the hanging piece of the support fitting that are hung on the opening edge of the through-hole, and the This serves as a source for maintaining the extended state of the support fitting on the edge of the through-hole, and as a result, it is possible to maintain the predetermined state of engagement even without fixing the support fitting to the through-hole forming wall such as the floor. Become.

ｌ’３を形成している。In the figure, reference numeral 1 indicates a supporting metal fitting improved according to the present invention, in which a metal plate such as an iron plate or a stainless steel mesh plate is made into a rectangular shape and bent into a roughly two-shape shape, thereby forming both ends of the intermediate piece 11. The bent ends 12. '
It forms l'3.

板２に対する外面つまり底面を受ける掛止片部となる。By hooking one bent end portion 12 to the floor surface at the opening edge of the through hole, the intermediate piece portion 11 is vertically provided along the inner surface of the through hole H, and the other bent portion 13 extends so as to protrude from the inner wall of the through hole H. Therefore, the bent end portion 13 becomes a hook portion that receives the outer surface, that is, the bottom surface, of the fireproof partition plate 2.
かかる掛止片部１３に関連して、中間片部１１には保持

In (a), a small piece formed in an L-shape is formed into an intermediate piece by means such as welding. 11 is an example. (b) In the case of (c), such a side piece is not required, and the intermediate piece 11
The holding piece 14 is formed by making a notch in itself and bending the part inscribed in the cut line to protrude.

しい。It is preferable for the retention function that the distance between the holding piece 14 and the hooking piece 13 corresponds to the thickness t of the fire-resistant partition plate 2, and that the fire-resistant partition plate 2 is in close contact with the fire-resistant partition plate. If the mechanical strength of the plate cannot be increased, it is preferable to make it slightly larger than the thickness of the plate so that no excessive force is applied to the fireproof partition plate.

ている。Figure 3 shows a fire-resistant partition plate 2 made of calcium silicate plate.
This figure shows the preferred positional relationship of the support fitting 1 for each month, and the separation width l of the holding piece I4 with respect to the hanging piece 13.
is made larger than the thickness t of the fire-resistant partition plate 2, and a slight gap g (approximately 1,511I11) is obtained between the holding piece 14 and the fire-resistant partition plate 2 during installation. .

。In addition, when using a calcium silicate plate as a fire-resistant partition plate, if the problem of pressure load on the fire-resistant partition plate can be ignored, the separation width l should be slightly narrower than the plate thickness t (about 0.5 mm). It is also possible. This is possible because it is a chalk-like calcium silicate plate.

ある。The two-split fireproof partition plate 2 is aligned with the cable C from the side, and the cable is inserted into the through hole 21 formed by closing the divided parts 22, and the fireproof partition plate A support fitting 1 is provided for each of the divided pieces 2. That is, the side edge of the plate is fitted between the locking piece 13 and the holding piece 14 of the support fitting 1. Then, the fireproof partition plate 2 is suspended from the plurality of support fittings 1 and lowered into the through hole H from above the floor F, and the bent end 12 on the upper end side of the metal fittings 1 is latched to the floor surface. This allows it to be used as a predetermined framework.

As this fireproofing material, HF putty (manufactured by Hitachi Cable, Ltd.) containing borax as a main ingredient is suitable. Furthermore, the division part of the fireproof partition plate 2 itself and the gap between it and the cable C,
Furthermore, in order to seal the gap between the fireproof partition plate 2 and the inner wall of the through hole H, a putty-like plugging material such as HiSeal (manufactured by Hitachi Cable, Ltd.) may be applied before filling with the HF putty. .

Since the movement of the support metal fittings during construction can be controlled, there is no need to temporarily fix the metal fittings, and the fire-resistant partition plate will not tilt in the through hole and become blocked during construction. It can be easily set in a normal position at 4 degrees without being stuck in the correct position or falling off the metal fittings. Therefore, the initial objective of providing a fire prevention structure that can be constructed extremely easily and without any danger without requiring any temporary fixing work to the supporting metal fittings to be hung has been more than achieved.
