A fireproofing treatment is performed between the through hole and the wiring / pipe material on the fireproof partition wall. This fireproofing treatment is performed, for example, to prevent the inflow of flame, smoke, or toxic gas to the other side through the through-hole when a fire or the like occurs on the front side of one wall across the fire prevention compartment wall. Is done. In other words, the fireproofing process closes the space between the through hole and the wiring / piping material in the event of a fire, etc., thereby preventing the flow of flame, smoke, or toxic gas to the opposite side of the fire. ing.

When fireproofing is performed on a through-hole provided for penetrating the wiring / pipe material, first, a frame body manufactured by sheet metal processing or the like is fitted into the through-hole to reinforce the periphery of the through-hole. Next, after laying the cable rack and the cable in the through hole reinforced with the frame, the gap between the cable rack and the frame is filled with a refractory material. As a frame used for through-hole reinforcement of such a fire-resistant treatment method, a separable substrate that covers the upper, lower, left, and right opening edges of the through-hole from the inside of the through-hole on one end side of the through-hole, and the substrate A slidable combination in the direction of the other end of the through hole is provided to form a subdividable sub-board that covers the upper, lower, left and right opening edges of the other end of the through hole (for example, Patent Document 1).

Yes. The frame component 12 is formed by forming a rectangular metal plate into an L shape.

  The abutting portion 21 has an abutting surface 21 a that is inserted into the through-hole 11 and abuts against the fire prevention partition wall W on the inner surface of the frame component 12 formed in an L shape. The width of the abutting portion 21 is formed to be an integral division of the length of the long side of the refractory material 16 (half the length in this embodiment). Further, the width of the contact portion 21 is formed to be an integral multiple of the thickness of the refractory material 16 (three times in this embodiment). Here, the width of the contact portion 21 is parallel to the peripheral edge portion of the through hole 11 in a state in which the frame constituent material 12 is inserted into the through hole 11 and the contact portion 21 is disposed in contact with the fire prevention partition wall W. Is the length of the part. On the other hand, the height of the abutting portion 21 is set to a height at which the abutting portion 21 can be brought into contact with and adhered to the fire prevention partition wall W. Here, the height of the contact portion 21 refers to the length of the side that forms the contact surface 21a together with the side in the width direction. A double-sided adhesive tape 22 is provided on the contact surface 21 a of the contact portion 21.

For example, as shown in FIG. 7 (b), the frame constituent members 12 may be connected to each other with an adhesive tape 27 on the surface opposite to the abutting portion 21 of the arranged spanning portion 23. Even if comprised in this way, while being able to bend | fold and isolate | separate per frame structural material 12 unit, weight reduction can be achieved.

In the third embodiment, a configuration in which the frame component 12a with the extended portion is extended may be connected. In this case, the connecting portion 25 is preferably provided at a place other than the extension portion 23b.
Next, a technical idea that can be grasped from the above embodiment and another example will be added below.

(A) A frame body forming method for a hollow fireproof partition wall according to claim 1, wherein a plurality of the frame-shaped structural members having the same shape are arranged on the entire circumference of the through hole to form a frame body.
(B) The hanging portion includes a bent portion on a surface opposite to a surface to which the abutting portion is connected, and the bent portion tilts the tip of the hanging portion with the bent portion as a base point. It is formed in such a manner that the front end portion of the spanning portion of the frame constituent material is tilted with the bent portion as a base point, and is brought into contact with the wall surface on the side opposite to the side on which the frame constituent material is inserted. The method for forming a frame of a hollow fireproof compartment wall according to claim 1.

(A) is a front view of the through-hole which gave the fireproof process, (b) is the sectional view on the AA line of (a). The perspective view of a frame structural material. (A) is a perspective view which shows the direction which inserts a frame structural material, (b) is a perspective view which shows the arrangement | positioning state of a frame structural material. (A) is a front view of a through-hole, (b) is a front view of a through-hole showing a state in the middle of frame formation, and (c) is a front view of a through-hole showing a state in which the frame is completed. (A) is a perspective view of the frame component material of 2nd Embodiment, (b) is the side view, (c) is a side view of the frame component material of the state which bent the front-end | tip. (A) is a top view which shows the attachment state of the frame structural material of 2nd Embodiment, (b) is the BB sectional drawing of (a), (c) bent the front-end | tip of the spanning part (a BB line sectional drawing of). (A) is a perspective view of the frame structural material of 3rd Embodiment, (b) is a perspective view which shows the modification of 3rd Embodiment. The perspective view which shows the modification of the insertion method of a frame structural material.
