Description

  The present invention relates to a fitting having fire protection.

  Fittings with fire protection are equipped with a heated foam between the frame and the shoji to ensure fire protection in the event of a fire. It is desirable that a tight line for a continuous flame is formed over the entire circumference.

  In the case of a fitting, when a frame forming an opening is provided with an openable / closable shoji, a hinge, for example, may be provided between the frame and the shoji as an attachment member. When the size of the hinge is large, the hinge itself is required to have high rigidity in order to support the hinge. For this reason, the portions of the hinge fixed to the frame and the shoji each have a rib or the like to increase rigidity.

As in the case of the above fittings, in fittings in which the shoji is fixed to the frame by a hinge having high rigidity, the surface of the fixed hinge has irregularities, so even if a heating foam material or the like is attached, the bonding area is sufficient. There is a possibility that it cannot be secured and cannot be stuck, or there is a possibility that adhesion is difficult, and there is a problem that a tight line cannot be continuously formed in a range where a hinge is provided, and fire resistance is reduced.
The present invention has been made in view of such a problem, and an object of the present invention is to provide a fitting having higher fire resistance.

  In order to achieve such an object, the fitting of the present invention has a frame forming an opening, a shoji provided in the opening, and a plurality of protrusions on a surface, and is attached to a portion where the frame and the shoji face each other. A mounting member, comprising a flat portion that forms a flat surface covering the plurality of protrusions that the mounting member has, a cover member that is fixed to the frame or the sash to which the mounting member is mounted, And a heated foam material adhered to the flat portion.

  According to such a fitting, a mounting member having a plurality of protrusions on the surface is mounted on a portion where the frame body and the shoji are opposed to each other, and a cover member having a flat portion covering the surface of the mounting member. The heated foam material is adhered to the flat part of. For this reason, the heating foam material is bonded not to the surface of the mounting member having a plurality of protrusions but to the flat portion of the cover member that covers the surface of the mounting member. Can be provided. For this reason, even if an attachment member having a plurality of protrusions is provided on the surface of the portion where the frame body and the shoji face each other, the heated foam material is unlikely to come off and can be more securely arranged. It is. For this reason, a tight line for a continuous flame is easily formed at a portion where the frame and the shoji face each other, so that it is possible to provide a fitting with higher fire resistance.

In such fittings, it is preferable that the cover member includes a protruding portion that protrudes from the flat portion and the heated foam material is disposed between the flat member and the flat portion.
According to such a fitting, since the heating foam is disposed between the flat portion and the projection protruding from the flat portion of the cover member, the movement of the heating foam in the peeling direction is restricted by the projection. Is done. For this reason, since the heat-foamed material is harder to peel off, it is possible to more reliably keep the heat-foamed material on the flat portion.

In this fitting, it is preferable that a heating foam material is provided between the frame and the shoji so as to be connected to the entire circumference together with the cover member.
According to such a fitting, between the frame and the shoji, the cover member in which the heating foam is provided on the flat portion and the heating foam provided with the cover member are connected to the entire circumference. Therefore, the heating foam material is provided over almost the entire circumference. In a portion where the frame and the shoji face each other, it is possible to provide higher fire protection than a case where the heating foam material is not provided over the entire region where the attachment member is provided.

In such a fitting, it is preferable that the attachment member is a hinge that supports the sash on the frame so as to be freely opened and closed.
According to such a fitting, for example, a hinge having a plurality of protrusions on its surface by being reinforced by a rib or the like to increase rigidity can support a large sash, so that a fitting of a large size can be used. Even so, it is possible to provide higher fire protection performance.

A bent portion 8e as a protrusion bent and inclined so as to be gradually inclined away from the frame prospect surface portion 30a and a frame projected surface portion 30a extending from the tip of the curved portion 8e and moving away from the curved portion 8e. And an approaching front end portion 8f. The distal end of the distal end proximity portion 8f is spaced from the frame prospect surface 30a.

  On the cover member 8, thermally expandable graphite 9 as a heating foam material is attached to both surfaces of the flat portion 8a and surfaces of the facing portion 8d on the second fixing portion 42b side. Further, on the frame prospect surface portion 30a of the lower frame 32, the thermally expandable graphite 9 is provided so as to be connected to the cover member 8 even at a portion where the cover member 8 is not provided in the longitudinal direction. At this time, as shown in FIG. 5B, the thermally expandable graphite 9 is also provided between the bent portion 8e and the front end proximate portion 8f and the frame prospect surface portion 30a.

  Between the frame 2 and the frame 30, not only between the lower frame 22 and the lower frame 32, but also between the upper frame 21 and the upper frame 31, and between the left vertical frame 23 and the left vertical frame 33. The heat-expandable graphite 9 is also provided between the right vertical frame 23 and the right vertical frame 33, respectively.

I have. Further, the thermally expandable graphite 9 is attached to the left and right vertical frames 33 over the entire length of the left and right vertical frames 33 on the outdoor portion of the left and right vertical frames 33.

  According to the fitting 1 of the present embodiment, a hinge 4 having a plurality of frame-side ribs 42c on its surface is attached to a portion where the frame 2 and the frame 30 of the shoji 3 face each other. Since the heat-expandable graphite 9 is provided on the flat portion 8a of the cover member 8 having the flat portion 8a covering the surface of the heat-expandable graphite 9, the heat-expandable graphite 9 can be provided while securing a sufficient bonding area. . Therefore, assuming that the hinge 4 having the plurality of frame-side ribs 42c is provided on the surface where the frame 2 and the frame 30 face each other, the thermally expandable graphite 9 is unlikely to come off and is more securely arranged. It is possible to keep. Therefore, it is easy to continuously form a tight line against the flame at a position where the frame 2 and the frame 30 face each other, so that it is possible to provide the fitting 1 having higher fire resistance.

  In addition, since the heat-expandable graphite 9 is disposed between the flat portion 8a and the bent portion 8e protruding from the flat portion 8a of the cover member 8 to the surface side, and the flat portion 8a, the heat in the direction in which the graphite 9 peels off. The movement of the expandable graphite 9 is restricted by the bent portion 8e. For this reason, since the thermally expandable graphite 9 is harder to peel off, it is possible to more reliably hold the same on the flat portion 8a.

  Also, between the frame 2 and the frame 30, the cover member 8 having the flat portion 8a provided with the heat-expandable graphite 9 and the heat-expandable graphite 9 are connected to the entire circumference, so that almost all A thermally expandable graphite 9 is provided around the circumference. For this reason, in the part where the frame body 2 and the frame body 30 face each other, it is possible to provide higher fire protection than when the heating foam material is not provided in the entire area where the hinge 4 is provided. When the thermally expandable graphite 9 foams in a narrow space between the lower frame 22 and the lower frame 32, the thermally expandable graphite 9 foamed between the lower frame 22 and the lower frame 32 is filled. For this reason, even if the thermally expandable graphite 9 is not provided on the screw stopper 8 b and the inclined portion 8 c of the cover member 8, the foamed thermally expandable graphite 9 is slightly removed without the thermally expandable graphite 9. It is also possible to form a tight line with respect to the flame connected to the entire circumference by going into the space. Incidentally, the thermally expandable graphite 9 may be provided on the screw stopper 8b and the inclined part 8c.

  Further, even if the hinge 4 is reinforced by the frame-side rib 42c or the frame-side rib 41a in order to increase the rigidity and the surface of the hinge 4 has a plurality of irregularities, it is possible to surely provide the heat-expandable graphite 9. Since it is possible, it is possible to support a large sash 3. For this reason, even in the case of a fitting having a large size, it is possible to provide higher fire prevention performance.

  In the above-described embodiment, the example in which the cover member 8 and the thermally expandable graphite 9 are provided on the side of the frame-side fixing portion 42 fixed to the lower frame 32 in the hinge 4 has been described. The cover member 8 and the heat-expandable graphite 9 may be provided on the side of the frame-side fixing portion 41 fixed to the frame projection surface portion 2a of the lower frame 22.

Further, in the above embodiment, the attachment member is a hinge, but the attachment member is provided in a space having a possibility of penetrating the inside and outside of the room, as long as it is a member that blocks continuous provision of the heating foam material, It is not limited to hinges.
In the above embodiment, the heat-expandable material is the heat-expandable graphite 9. However, the heat-expandable material is not limited to the heat-expandable graphite as long as it is a refractory material that expands when heated.
