  Dimensions of thermal expansion material 2, that is, length (length L1 of first portion, length L2 of second portion), width (length D1 of first portion, length D2 of second portion) The thickness T is not particularly limited, and is appropriately set in accordance with the dimensions of the frame 11.

  The thermal expansion material 2 is preferably formed into the above-described shape by injection molding, but may be formed by extrusion molding, compression molding, or the like. Molding by injection molding is preferable because the thermal expansion material 2 can be produced with high yield without waste and can be molded into a complicated shape. Alternatively, a wide sheet-like thermal expansion material may be produced, and the sheet-like thermal expansion material may be shaped by cutting off the L-shaped thermal expansion material 2 in plan view.

  In order to attach the fire protection material 1 to the frame 21, the fire protection material 1 is provided on the surface of the attachment frame 11 A of the frame 11 that extends over the rim 14 A to 14 D of the frame 11.

In other words, the fire protection material 1 is attached such that the corner portion (bent portion of the first portion 3 and the second portion 4) C1 of the fire protection material 1 is disposed at the corner portion C2 of the attachment frame 11A. The corner portion C1 of the fire protection material 1 being disposed at the corner portion C2 of the mounting frame portion 11A means that the pointed portion A1 of the end of the corner portion C1 of the fire protection material 1 is the corner portion of the corner portion C2 of the mounting frame portion 11A. Besides being disposed so as to abut A2, it also includes the case where the pointed portion A1 at the end of the corner C1 of the fire protection material 1 is disposed without abutted on the corner A2 of the corner portion C2 of the mounting frame 11A. In order to attach this kind of fire protection material over the entire circumference of the attachment frame portion 11A of the frame 11, the lengths D1 and D2 are set to appropriate lengths, and as shown in FIG. 2, four first embodiments The fire protection material 1 may be attached so that no gap is generated between the fire protection material 1 adjacent to the corner portions C2 at the four corners of the mounting frame 11A, or as shown in FIG. Between the fire protection materials 1 of the first embodiment attached, the conventional flat-plate shaped fire protection material 16 with flat front and back surfaces butts the end faces of the fire protection material 1 and the fire protection material 16 with each other And there may be no gap between them. The fire protection material 1 is attached to the frame 11 via an adhesive tape (not shown) or the like. The pressure-sensitive adhesive tape can be attached to the thermal expansion material 2 in advance, and in that case, it is preferable that a release paper (not shown) is further attached to the pressure-sensitive adhesive tape.

  As shown in FIG. 6, when a fire occurs, the fire protection material 1 (thermal expansion material 2) expands due to the heat of the fire, thereby closing the gap S between the window 10 and the frame 11.

Such a cosmetic material can be attached to the thermal expansion material 2 with an adhesive, an adhesive or the like.

  Further, the means for attaching the fire protection material 1 to the frame 11 is not limited to the adhesive tape, and physical fixing such as an adhesive or a screw may be used.

  Next, FIG. 9 and FIG. 10 show the appearance configuration of a frame 21 with a fire protection material (hereinafter simply referred to as a “frame”) according to a second embodiment of the present invention. The frame 21 of the second embodiment is for the sliding window 20 and is fixed to the opening 22 of a structural material such as a building wall (not shown) by a conventionally known method. In FIG. 10, the window 20 and the frame 21 are schematically shown, and the detailed structures of the window 20 and the frame 21 are not shown.

  The frame 21 has a rectangular shape in a front view, and is configured by combining four elongated side edges 21 a to 21 d in upper, lower, left, and right in a frame shape. Further, the frame 21 (each side edge 21a to 21d) is U-shaped in cross section, and a recessed groove 26 is formed on the inner peripheral surface of the frame 21 along the longitudinal direction. Therefore, the frame 21 (the side edges 21a to 21d) includes the substrate 21A constituting the recessed groove 26 and a pair of side plates 21B which rise from both side edges of the substrate 21A. The substrate portions 21A of the side edge portions 21a to 21d are circumferentially connected such that the surfaces form an angle of 90 degrees (orthogonal). Further, the side plate portions 21B of the side edge portions 21a to 21d are connected in a circumferential shape so that the surfaces are flush with each other. The material of the frame 21 is not particularly limited, and may be, for example, aluminum, synthetic resin, composite of aluminum and synthetic resin, wood, steel, or the like.

  The two windows 20 are formed by fixing a weir 24 around the panel 23. The weir 24 is configured by combining vertically and horizontally elongated rims 24A to 24D in a frame shape. The crucible 24 may be made of any material such as metal such as aluminum, wood, synthetic resin and the like. The panel 23 may be made of any material such as glass or synthetic resin. When the two windows 20 are closed, the upper rim portion 24A, the lower rim portion 24B, the left rim portion 24C or the right rim portion 24D of the crucible 24 face the substrate portion 21A of the frame 21 when the window is closed. The windows 25 are opened by rotating the rods 25 downward and sliding the wedges 24 in the lateral direction.

  The fire protection material 1 at least includes a thermal expansion material 2 having fire resistance and thermal expansion, as shown in FIG. The thermal expansion material 2 includes at least a plate-like first portion 3 and a plate-like second portion 4 integrally formed with the first portion 3 and bent from the first portion 3; The first portion 3 and the second portion 4 are connected such that the front surfaces and the back surfaces form an angle, that is, the other portion 4 stands on one side edge of one portion 3 It is in line. Further, the first portion 3 and the second portion 4 are arranged to be orthogonal to each other, and are L-shaped in side view. The front and back surfaces refer to the surface of the flat plate material having the largest area.

  The raw material of the thermal expansion material 2 is the same as that of 1st Embodiment, and detailed description is abbreviate | omitted here. Dimensions of the thermal expansion material 2, that is, length L, width (length D1 of the first portion, length D2 of the second portion), thickness (thickness T1 of the first portion, thickness of the second portion The dimension T2) is not particularly limited, and is appropriately set in accordance with the dimensions of the frame 21.

  The thermal expansion material 2 is preferably formed into the above-described shape by injection molding, but may be formed by extrusion molding, compression molding, or the like. Molding by injection molding is preferable because the thermal expansion material 2 can be produced with high yield without waste and can be molded into a complicated shape. Alternatively, a columnar thermal expansion material may be produced, and the thermal expansion material 2 in an L-shape in side view may be cut out of the columnar thermal expansion material.

  When attaching the fire protection material 1 to the frame 21, the inner peripheral surface of the frame 21 facing the ridge 24, that is, the surface of the base 21 A of the frame 21 extending overlapping the end face of the rim portions 24A to 24D of the ridge 24 The fire protection material 1 is attached. At this time, the fire protection material 1 is attached such that the first portion 3 of the fire protection material 1 abuts on the substrate portion 21A and the second portion 4 abuts on the side plate portion 21B. In other words, the corner portion C1 of the fire protection material 1 (the bent portion of the first portion 3 and the second portion 4) abuts on the corner portion C3 of the substrate portion 21A of the frame 21 and one side plate portion 21B. The fire protection material 1 is attached. In addition, in order to attach the fire protection material 1 over the perimeter of the board part 21A of the frame 21, the length L is set to an appropriate length, for example, four fire protection materials 1 are the side edges 21a of the top, bottom, left and right of the frame 21. It attaches so that a clearance gap may not arise between the fire prevention materials 1 which adjoin along -21d. The fire protection material 1 is attached to the frame 21 via an adhesive tape (not shown) or the like. The pressure-sensitive adhesive tape can be attached to the thermal expansion material 2 in advance, and in that case, it is preferable that a release paper (not shown) is further attached to the pressure-sensitive adhesive tape.

  As shown in FIG. 12, when a fire occurs, the fire protection material 1 (thermal expansion material 2) expands due to the heat of the fire, thereby closing the gap S between the window 20 and the frame 21. In this way, it is possible to reduce or prevent the intrusion of fire or smoke from between the window 20 and the frame 21.

  The frame 21 is not only the corner portion C3 of the substrate portion 21A and the side plate portion 21B, but also the fireproof material when the other plate-like portion is erected from the substrate portion 21A between the pair of side plate portions 21B. By appropriately adjusting the dimension of 1, the corner portion C1 of the fire protection material 1 abuts on the corner portion between the substrate portion 21A and the plate-like portion, that is, the first portion 3 of the fire protection material 1 is a substrate portion The fire protection material 1 can be attached such that the second portions 4 respectively hit the plate-like portion 21A.

As described above, according to the fireproof material-attached frame 21 of the second embodiment, for example, the side plate 21B and other plate-like parts project from the substrate 21A of the frame 21 and the shape of the frame 21 is complicated. Since the thermal expansion material 2 includes the first portion 3 and the second portion 4 bent from the first portion 3 and has a shape conforming to the shape of the frame 21, The fire protection material 1 can be attached to the part having the complicated shape without any seam. Therefore, the frame 21 can be made excellent in fire resistance. In addition, since the fire protection material 1 can be easily attached to the frame 21, the attachment work can be made highly efficient at the time of attachment.

  As mentioned above, although 2nd Embodiment of this invention was described, 2nd Embodiment is not limited to the thing of the said content, A various change is possible unless it deviates from the meaning. For example, although the first portion 3 and the second portion 4 of the thermal expansion material 2 are orthogonal, they may not be orthogonal as long as they are bent. Moreover, although both the 1st part 3 and the 2nd part 4 of the thermal expansion material 2 are flat form, according to the shape of the frame 21, for example, the 2nd part 4 may be made into a curved plate shape etc.

In FIG. 13, the thermal expansion material 2 further includes a plate-like third portion 5 integrally formed with the first portion 3 and bent from the first portion 3, and the two portions 4 and 5 are With respect to the first portion 3, the surfaces are erected at an angle from a pair of opposing side edges of the first portion. That is, the thermal expansion material 2 is formed such that the three plate-like portions 3 to 5 are integrally formed, and two adjacent portions form a right angle. In this case, the fire protection material 1 is attached to the frame 21 such that the first portion 3 contacts the substrate portion 21A of the frame 21 and the second portion 4 and the third portion 5 contact each side plate portion 21B of the frame 21. be able to.

  In addition, the thermal expansion material 2 may have a shape in which the front end portions E of the second portion 4 and the third portion 5 of the U-shaped thermal expansion material 2 in FIG. 13 are bent outward. In this case, as shown in FIG. 14, the fire resistance can be improved by attaching the fire protection material 1 to the frame 21 such that the tip E bent outwards contacts the end face of the side plate 21 B of the frame 21.

  In addition, the fireproof material-attached frame 21 of the second embodiment also includes the fireproof material 1, the thermal expansion material 2, and a decorative material (not shown) covering at least a part of the thermal expansion material 2 It can be done. Further, the means for attaching the fire protection material 1 to the frame 21 is not limited to the adhesive tape, and physical fixing such as an adhesive or a screw may be used.
