The front wall portion 15 has an extending portion 15a extending in the width direction of the refractory material fixing hardware 10 (extending direction of the beam H).

In the width direction of the refractory material fixing hardware 10, a first side wall 16, a second side wall 17, and a third side wall 18 are provided as side walls at each of both end portions of the front wall 15. More specifically, in the width direction of the refractory fixing hardware 10, the first side wall portion 16 and the second side wall portion 17 are arranged near the engaging portion 11, and the third side wall portion 18 is located near the engaging portion 11. (Specifically, at the end of the extending portion 15a).

The first side wall portion 16 extends in the vertical direction of the refractory material fixing hardware 10 . The three second side wall portions 17 are provided at a predetermined distance from each other in the vertical direction of the refractory material fixing hardware 10 .

The engaging portion 11 protrudes from the side end portion of the front wall portion 15 in the same direction as each side wall protrudes (FIG. 4). Since the direction in which the refractory material fixing hardware 10 is engaged with the flange portion of the beam H matches the direction in which each side wall protrudes, the refractory material may fall off from the holding portion 12 of the refractory material fixing hardware 10 during work. Storage is suppressed.

An upper notch 13c is formed in the corner formed by the upper wall 13 and the front wall 15, and an upper notch 13c is formed by cutting out the corner. A lower notch 14c is formed by cutting out the corner. The first engaging portion 11a and the second engaging portion 11b are arranged apart from the front wall portion 15 in the thickness direction (in other words, the front-rear direction of the refractory material fixing hardware 10). That is, in the thickness direction, for example, a gap C of about 12 mm is formed between the side end of the flange portion of the beam H and the facing board P (FIG. 14, which will be described later). By using the refractory material fixing hardware 10 of this embodiment, it becomes possible to secure the gap C required in the parting wall 1 between the flange portion of the beam H and the facing board P.

In addition, in the refractory material fixing hardware 10, since the upper wall part 13, the lower wall part 14, the front wall part 15, and each side wall are constructed by bending one steel plate (metal plate), these parts are made into one part. It is integrated as a. Therefore, the refractory material fixing hardware 10 of this embodiment has a simple structure and is easier to handle. However, the present invention is not limited to this, and each part constituting the refractory fixing hardware 10 was originally composed of separate parts, and when assembling the refractory fixing hardware 10, the parts were connected and integrated. Good too. In such a case, the parts may be connected by welding if the steel plates constituting each part are sufficiently thick.

<About usage of refractory material fixing hardware 10 (refractory material fixing parts)>
As shown in FIG. 10, the engaging portion 11 of the refractory material fixing hardware 10 configured as described above engages with the side end portion of the flange portion from the side of the flange portion in the thickness direction.

It engages with the lower flange side end H21. In this way, since the refractory fixing hardware 10 engages with the flange portion of the beam H at two locations, the upper and lower sides, the positions of the refractory fixing hardware 10 and the refractory material in the beam space H4 become stable. .

At this time, the first engaging portion 11a and the second engaging portion 11b are urged to expand in the vertical direction. In this state, the upper leaf spring part 13b comes into contact with the lower surface of the upper flange part H1, thereby biasing the bent part 13a and the leaf spring part 13b downward, and the lower leaf spring part 14b contacts the lower surface of the upper flange part H1. By coming into contact with the upper surface of the portion H2, the bent portion 14a and the plate spring portion 14b are urged upward. Therefore, the state of engagement of the refractory material fixing hardware 10 with the beam H is stabilized.

In particular, when the refractory material is held by the first holding part 12a, the upper bent part 13a and the leaf spring part 13b contact the upper surface of the refractory material, and the lower bent part 14a and the leaf spring part 14b contact the upper surface of the refractory material. Since it comes into contact with the lower surface of the refractory material, the state of engagement of the refractory material fixing hardware 10 with the beam H becomes even more stable.

In this way, in the refractory material fixing hardware 10, the first engaging part 11a sandwiches the upper flange part H1 between the upper wall part 13 and the leaf spring part 13b, and the second engaging part 11b holds the lower flange part H2. , sandwiched between the lower wall portion 14 and the leaf spring portion 14b. At this time, since the sizes of the first engaging part 11a and the second engaging part 11b that sandwich the flange part change, the refractory material fixing hardware 10 has different thicknesses (for example, about 6 mm, about 9 mm, about 12 mm, etc.). It is possible to engage with the flange portion.

As shown in FIGS. 10 to 12, the refractory material fixing hardware 10 is arranged around a connecting portion Ha between a certain beam H and an adjacent beam H (FIG. 10). More specifically, the refractory material fixing hardware 10 is placed at the protruding corner 1a of the parting wall 1 (the corner where the parting wall line 1b of the parting wall 1 is L-shaped) (FIGS. 11 and 12). . By using the refractory material fixing hardware 10, it is possible to appropriately and easily stop the parting wall 1 in the middle of the beam H (distance section) extending in a predetermined direction in a building, specifically at the protruding corner 1a. It becomes possible.

When the engaging part 11 engages with the flange part of the beam H, specifically, the first engaging part 11a engages with the upper flange part H1, and the second engaging part 11b engages with the lower flange part. When engaged with H2, the refractory material held by the holding part 12 is placed in the beam space H4 of the beam H (FIG. 10). In other words, the refractory material is arranged between the refractory material fixture 10 and the web portion H3 of the beam H.

As described above, according to the refractory material fixing hardware 10, by holding the refractory material in the holding part 12 and engaging the engaging part 11 with the flange part of the beam, rock wool, gypsum board, etc. can be placed in the beam space H4. The refractory material can be easily placed and fixed in an appropriate position.

Further, according to the refractory material fixing hardware 10, the refractory material is wrapped around the connecting portion Ha between one beam H and the adjacent beam H, that is, the protruding corner portion 1a of the parting wall 1 (partition wall). Since it becomes possible to appropriately fix the refractory material in a difficult position, even if the parting wall 1 is complicated and has corners, construction can be carried out appropriately.

<About the construction method of parting wall using fireproof material fixing hardware 10 (fireproof material fixing parts)>
Next, a procedure for constructing the parting wall 1 using the above-mentioned refractory material fixing hardware 10 will be explained. The method of constructing the parting wall 1 (partition wall) of this embodiment is to hold the refractory material in the holding part 12 of the refractory material fixing hardware 10, and to attach the engaging part 11 of the refractory material fixing hardware 10 to the flange part of the beam H. and fixing the facing board P to the front wall part 15 of the holding part 12. Each procedure will be explained in detail below.

First, the refractory material fixing hardware 10 is prepared, and the refractory material is held in the holding part 12.

It engages with the side flange side end H21. As a result, the refractory material fixing hardware 10 and the refractory material are attached to the beam H, and the refractory material is placed in the beam space H4 (FIGS. 10 and 12).

Thereafter, the panel board P is fixed to the front wall portion 15 of the refractory material fixing hardware 10 using the fastening members B (FIGS. 13 and 14). At this time, if the gypsum board PB is held as a fireproof material, the facing board P is fixed with the fastening member B while avoiding the first holding part 12a or the second holding part 12b where the gypsum board PB is held. do.

Specifically, when gypsum board PB is held as a fireproof material, in order to prevent gypsum board PB from being broken, avoid the second holding part 12b where gypsum board PB is held. The facing board P is fixed with the fastening member B (FIGS. 9A and 13). In this way, the refractory material fixing hardware 10 has the two holding parts 12, the first holding part 12a and the second holding part 12b, so that even if the gypsum board PB is held as the refractory material, the face material It can be used as a base for the board P.
