JP 2004-169454 A

In order to make it easier to attach, remove and open / close the shoji, the joinery described above is between the lower inner surface of the frame and the lower outer surface of the shoji, and between the upper inner surface of the frame and the upper outer surface of the shoji. It is common to have a gap.
On the other hand, in the case of fittings such as squeezed windows, casement windows, protruding windows, doors, etc., the shoji may hang down by its own weight due to the part of the gap below that is melted or softened in the event of a fire. .
When the shoji hangs down in this manner, a gap between the upper and outer surfaces of the shoji and the upper and inner surfaces of the frame becomes large, and air and flame are easy to pass.
On the other hand, in fittings such as inward windows and external windows, the shovel of the shoji is the gap between the upper inner surface of the frame and the upper and outer surfaces of the shoji before it melts and softens in the event of a fire. For example, when fireproof materials such as a thermal expansion material are provided on the firewood, the original fireproof function cannot be achieved due to the displacement of the fireproof material due to the heat elongation of the firewood. May occur.

As shown in FIG. 3 and FIG. 4, the metal fitting 100 is attached to the outer side surface of the metal vertical rod 8 a of the door-end rod 8, that is, the vertical outer surface of the shoji 5.
As shown in FIG. 5, the metal fitting 100 has a substantially rectangular plate shape surrounded by one end surface 101 in the width direction, the other end surface 102 in the other width direction, the upper end surface 103, and the lower end surface 104. The one-side upper corner portion 105 where the one-side end surface 101 and the upper end surface 103 are continuous is an arc surface, and the one-side lower corner portion 106 where the one-side end surface 101 and the lower-end surface 104 are continuous is an angled surface with no corners. Yes.
The arc surface only needs to constitute a surface having an arc shape when viewed from the front in FIG. Moreover, the inclined surface should just comprise the surface which becomes an inclined shape in front view.

The above-mentioned metal fitting 100 is formed by screwing a fixing tool, for example, a screw 108, into a metal part, for example, a screw hole of the metal lower collar 7a from the mounting hole 107, so that one end face 101 is on the indoor side and the other end face 102 is on the other side. The other end surface 102 faces the indoor side surface of the outward projecting portion 81 of the metal vertical rod 8a, which will be described later, toward the outdoor side, and the lower end surface 104 thereof is the lower end surface 8c of the door rod 8 and the lower end surface 7c of the lower rod 7. That is, the lower end surface 104 and the inner side surface of the lower metal frame 3a of the lower frame 3 (the portion facing the lower end surface 104 on the lower inner side surface of the frame 1) are parallel to each other. It is attached to become.
That is, the clearance S1 between the lower end surface 104 of the metal fitting 100 and the inner side surface (the lower inner side surface of the frame 1) of the metal lower frame 3a of the lower frame 3 is the lower end surface 9c (lower and outer sides of the shoji 5) The gap S2 between the side surface) and the inner side surface of the metal lower frame 3a.

In this case, when a part of the shoji door side hangs down due to the dead weight of the shoji due to part melting or softening in the event of a fire, the lower end surface 104 of the metal fitting 100 is a metal part of the lower frame 3, For example, since it abuts against the inner side surface of the metal lower frame 3a and prevents further drooping, drooping due to its own weight on the side of the shoji door can be suppressed.
Therefore, a large gap does not occur between the upper part of the shoji door side and the upper frame, and air and flame are difficult to pass through, which is preferable in terms of fire prevention.
In addition, since the entire length in the width direction of the lower end surface 104 of the metal fitting 100 is in contact with the inner side surface of the metal lower frame 3a and the sliding resistance of the contact portion is large, the shoji is difficult to move in the indoor exterior direction. It can suppress falling off to the outside.

The metal fitting 100 described above is plate-shaped and attached to the outer surface of the metal vertical rod 8a of the door toe 8, so no extra space is required to attach the metal fitting 100, and this metal fitting 100 obstructs the opening and closing of the shoji. In addition, the size required between the lower end surface 8c of the door rod 8 (that is, the outer surface of the rod assembly) and the metal lower frame 3a of the lower frame 3 (that is, the inner peripheral surface of the frame). Can be ensured.
In other words, between the lower outer surface of the shoji frame assembly and the lower inner surface of the frame, the shoji can be attached and removed, the shoji can be opened and closed easily, and parts (eg, vertical arm) can be attached. In addition, a gap of a predetermined size is required, and if the metal fitting 100 is not provided, the shoji door end side hangs down by the gap.

  Further, the one side upper corner portion 105 facing the room side of the metal fitting 100 is an arc surface, and the one side lower corner portion 106 has no corner portion and is an inclined surface. It is safe, and when the metal fitting 100 interferes with the lower frame during normal use, it can be smoothly climbed and the shoji can be moved to the closed position and closed.

Although this embodiment is a vertical extension window, it is located between the lower outer surface of the frame assembly and the lower inner surface of the frame in the state where the shoji is in the closed position, such as an outer opening window, an opening window, and a protruding window. This is applicable to joinery where there is a large gap in the door and the shoji is hanging under its own weight in the event of a fire. However, in the case of a fitting that hangs the entire shoji, such as sliding windows or protruding windows, it is necessary to attach brackets to the lower parts of the left and right vertical fences. It can also be applied to sliding-type fittings such as sliding windows and single-sided windows. The end face abuts on a metal part such as the upper surface of the lower frame, and can prevent drooping.
In addition, in the case of a joinery that does not hang down the shoji, such as inward-facing windows and outward-facing windows, a bracket is attached to the upper part of the left and right vertical fences, and this bracket is placed above the upper outer surface of the saddle assembly. In the case where a vertical gutter heat-extends in the event of a fire, the upper end surface of the metal fitting can be brought into contact with the upper inner side surface of the frame to suppress the heat elongation. At this time, the shape of the metal fitting attached to the upper part of the vertical hook may be a shape in which the metal fitting 100 described above is turned upside down.

The screw connecting the lower portion of the door rod 8 and the lower rod 7 is also used as the screw 108 for attaching the metal fitting 100 described above, and another screw 109 is screwed into the screw hole 75a of the lower rod reinforcement 75. Are connected.

  As shown in FIGS. 6 to 9, the upper rod reinforcing material 65, the lower rod reinforcing material 75, the vertical rod reinforcing materials 85 and 95, the upper groove reinforcing material 66, the lower groove reinforcing material 76, and the vertical groove reinforcing materials 86 and 96 are thermally expanded. Each refractory material 110 is provided, and the refractory material expands in the event of a fire to hold the glass 10 with each groove reinforcing material.

  Since it is like this, the deformation | transformation by the heat | fever of a firewood is suppressed at the time of a fire, and it can hold | maintain so that the glass 10 may not drop | omit even if a firewood melts.

In addition, in the said embodiment, although an example was given and demonstrated about the aspect of the metal fitting, it does not restrict to this.
For example, as shown in FIG. 12, when the lower end surface 104 of the metal fitting 100 comes into contact with the lower inner surface of the lower frame 3 in the event of a fire, the outdoor side of the lower end surface 104 of the metal fitting 100 ( By providing a regulation metal fitting 130 facing the lower end side on the lower inner surface of the lower frame 3, the movement of the shoji 5 in the outdoor direction is suppressed by interference between the other end face 102 of the metal fitting 100 and the regulation metal fitting 130. In addition, the dropout from the frame 1 of the shoji 5 can be further suppressed. During normal operation, the regulation metal fitting 130 and the metal fitting 100 are not opposed to each other in the indoor / outdoor direction so that there is no hindrance during normal opening / closing.
At this time, as shown in FIG. 13, without using the restriction fitting 130, a restriction hole 131 is provided on the lower inner surface of the lower frame 3, and the restriction protrusion 132 that can be inserted into the restriction hole 131 is provided at the lower end surface of the fitting 100. When the lower end surface 104 of the metal fitting 100 comes into contact with the lower inner side surface in the event of a fire, the restriction projection 132 of the metal fitting 100 is inserted into the restriction hole 132 on the lower inner side surface, so It is also possible to suppress the movement toward. During normal opening and closing, the restricting protrusion 132 and the restricting hole 131 are made not to face each other in the indoor / outdoor direction.

Moreover, in the said embodiment, although the example which used the metal fitting in order to suppress drooping was mentioned and demonstrated, it is not restricted to this, You may form this metal fitting and this metal fitting in a shoji integrally. .
For example, as shown in FIG. 14, a part of the lower end surface of the metal vertical rod 8 a of the shoji 5 is protruded downward from the lower outer surface of the shoji 5 so as to face the metal portion on the lower inner surface of the frame 1. The gap between the lower end surface 134 of the portion 133 provided and protruded downward from the metal vertical rod 8a and the lower inner surface of the frame 1 is the lower outer surface (lower rod 7) of the shoji 5 and the lower inner surface of the frame 1. It can be made smaller than the gap between the two.
By doing in this way, like the above-mentioned embodiment, when the shoji 5 is suspended by its own weight in the event of a fire, the lower end surface 134 of the portion 133 protruding below the metal vertical rod 8a comes into contact with the lower inner side surface of the frame 1. The hanging of the shoji 5 can be controlled, and it is difficult for the flame to pass.
In addition, even in the case of a joinery that does not hang a shoji, such as an inside-down window or an outside-facing window, a part of the left and right metal vertical rods protrudes upward from the upper and outer surfaces of the frame assembly, causing a fire. In this case, when the vertical gutter heat-extends, the upper end surface of the protruding portion of the metal vertical gutter can come into contact with the upper inner side surface of the frame to suppress the thermal elongation.
Moreover, the part 133 protruded from the metal vertical hook may be provided with an inclined surface similar to the one-side lower corner part 106 of the metal fitting 100 shown in FIG. Moreover, in the said embodiment, although the frame 1 was comprised with the composite frame material of aluminum and resin, and the frame assembly of the shoji 5 was comprised with the composite frame material of aluminum and resin, the frame 1 was comprised with the aluminum frame material and the frame assembly. The body may be composed of aluminum frame material, the frame 1 may be composed of resin frame material, the frame assembly may be composed of resin frame material, and the frame 1 frame material and frame assembly These frame materials may be used in any combination of the above-mentioned frame materials and frame materials.
In addition, the best configuration for carrying out the present invention has been disclosed in the above description, but the present invention is not limited to this.
