The elastic member is provided on the glass frontage reinforcing material.

Preferably, the elastic member has an inclined portion between the fixed portion and the glass frontage reinforcing material, and the elasticity of the inclined portion urges the glass frontage reinforcing material downward.
According to the above configuration, when the double glazing fits in the glass groove via the grechan, the leaf spring-shaped elastic member is displaced so as to be substantially flush with the bottom surface of the glass frontage reinforcing material, so that the glass frontage reinforcement The material can be installed in a narrow space.
In addition, by forming a leaf spring-shaped elastic member integrally with the glass frontage reinforcing material by cutting and raising, the number of parts is not increased, and the step of fixing the elastic member by welding, riveting, etc. can be omitted, and the cost is reduced. The increase can be avoided.

The double glazing was housed via Grechan because each falling wall inside and outside the inside and outside of the glass frontage reinforcing material was slightly shorter than the length of each falling wall inside and outside the glass groove portion of the frame or frame. Occasionally, the falling walls of the indoor side and the outdoor side of the glass frontage reinforcing material are housed in the glass groove portion, and the falling walls of the glass frontage reinforcing material cannot be seen from the indoor side and the outdoor side, so that the interior appearance is good. Does not get worse.

By attaching the thermal expansion fireproof material formed in a flat plate shape and a strip shape in the swallowing direction of the double glazing of the glass frontage reinforcing material according to claims 1, 2 and 3, the double glazing and the glass frontage in the event of a fire. The fire-resistant material foamed by heat closes the gap between the reinforcing material and the glass groove gap generated by the transfer of the leaf spring-like elastic member, so the fire spreads around the glass groove and the double glazing. Can be prevented.

According to the present invention, when a fire breaks out, the glass frontage reinforcing material is displaced downward, so that the gap between the glass groove of the upper stile and the double glazing can be closed, and the spread of fire through the gap can be prevented. Can be done.

The combination stile 19a of the shoji 2 is composed of only the metal stile 26d.

In the glass groove 20a of each frame, as shown in FIGS. 1, 2, and 4, a glass frontage reinforcing material 31 formed by bending a thin metal plate into a groove shape so as to surround the outside of the Grechan 22 is formed in the glass groove. It is arranged over the entire length of 20a and is fixed to the metal frames 26a, 26b, 26c, 26d with screws 33. As described above, since the metal glass frontage reinforcing member 31 is provided in the glass groove portion 20a, the glass holding wall on the outdoor side of the glass groove 20a of the metal frames 26a, 26b, 26c, 26d is melted by the heat of the fire. Even if the resin covers 27a, 27b, 27c, 27d and the Grechan 22 are melt-peeled as described above, the glass 23a, 23b of the double glazing 21 can be prevented from falling off.

However, as shown in FIGS. 1, 2, and 3, the front stiles 18a and 18b and the combination stiles 19a and 19b of the outer sash 2 and the inner sash 3 are based on the lengths of the upper stiles 16a and 16b and the lower stiles 17a and 17b. It is long (generally, window shoji is vertically long rectangular). The metal frames 26a, 26b, 26c, 26d are made of an aluminum alloy, the coefficient of thermal expansion thereof is 23/1000000 / K, and the coefficient of thermal expansion of the glass 23a, 23b is 8-10 / 1000000 / K. The thermal expansion is about 1/3 of the thermal expansion of the aluminum alloy. Therefore, in the case of a fire or the like, the temperature rises to the limit where the aluminum alloy melts (about 660 ° C.). Therefore, between the glasses 23a and 23b and the glass groove at that time, a terrace window or the like is formed as shown in FIG. In the case of, a gap 20 of about 10 to 15 mm is generated, and even the falling walls 31a and 31b of the metal glass frontage reinforcing material 31 cannot be covered, and there is a possibility that fire spreads from this gap. It was.

Therefore, as shown in FIGS. 5 and 7, the metal glass frontage reinforcing material 31 has a substantially U-shaped cross section, and the inner falling wall 31a, the outer falling wall 31b, and the bottom wall 31c extend in the longitudinal direction. The bottom wall 31c having a substantially U-shaped cross section is provided with a plurality of elastic members 32 in the longitudinal direction (two in the figure). The elastic member 32 has a leaf spring shape. More specifically, the elastic member 32 is formed by cutting and processing a part of the bottom wall 31c in the opposite direction (that is, above) of the inner falling wall 31a and the outer falling wall 31b, and the inclined portion is formed. It has 32a and a fixing portion 32b as a free end portion substantially parallel to the bottom surface of the glass groove. A hole 32c for fixing with a screw 33 is provided in the central portion of the fixing portion 32b.

Explaining the case where heat such as a fire is applied to the stile with the upper stile 16a of the outer shoji 2, the resin cover 27a arranged on the indoor side as shown in FIG. 7 melts early or falls off due to the heat. It ends up. Further, as described above, the door end stile 18a and the combined stile 19a of the outer sash 2 undergo thermal expansion about three times as much as the thermal expansion of the glasses 23a and 23b, so that the bottom surface of the glass groove of the metal stile 26a and the double glazing The gap with 21, that is, the glass groove gap 20, becomes large. The metal glass frontage reinforcing member 31 is provided with a plurality of elastic members 32 in the longitudinal direction, and is fixed to the bottom surface of the glass groove of the metal frame 26a with screws 33 in the holes 32c of the fixing portion 32b. The elastic member 32 of the metal glass frontage reinforcing member 31 urges the glass frontage reinforcing member 31 in the direction away from the upper stiles 16a and 16b, that is, downward due to the elastic deformation of the inclined portion 32a. Or the resin cover 27a is melted by the heat and falls off, glass frontage reinforcement 31 made of metal (downward in FIG. 6) so as to compensate for the glass groove gap 20 is displaced, falling walls 31a, 31b holds the glasses 23a and 23b of the double glazing 21. This makes it possible to prevent the spread of fire from the gap 20.

Next, another embodiment of the present invention will be described with reference to the drawings. In these figures, the configurations corresponding to the first embodiment are designated by the same numbers and detailed description thereof will be omitted.
