TECHNICAL FIELD The present invention relates to fittings in consideration of fire resistance.

For fittings having frames and stiles made of aluminum alloy, there are provided fittings in which a steel reinforcing member is arranged inside a hollow structure in consideration of fire resistance. According to this type of fittings, steel reinforcing materials have a smaller coefficient of linear expansion than frames and stiles made of aluminum alloy. There are advantages such as being able to maintain the shape of the fittings.

In addition, in fittings that consider fire resistance, multi-layered glass composed of glasses with different fire resistance strengths is often used as the face material of shoji. As double glazing, for example, a combination of wired glass and float glass is common. According to this fitting, even when the fitting is heated to a temperature at which the float glass is thermally cracked, the wire glass with high fire resistance remains in the shoji, preventing the occurrence of a flame path inside and outside the room. (See, for example, Patent Document 1).

JP 2014-109091 A

By the way, in fittings in which reinforcing materials made of steel are arranged inside frames and stiles made of aluminum alloy, if the frames and stiles are heated to a temperature before they melt, the frames and stiles will be damaged. Even if the thermal deformation is restricted by the reinforcing material, the frame or the stile may be deformed in the out-of-plane direction. Therefore, even if the temperature is such that the glass with high fire resistance softens and loses its self-standing, there is a concern that the glass may fall off if the vertical frame that serves as the garnish is greatly deformed in the out-of-plane direction. Considering fire resistance, it is not necessarily preferable. In particular, fittings with inner shoji and outer shoji have two vertical stiles that may be deformed due to the above-mentioned reasons, and glass with high fire resistance strength is placed on the outside of the room. Since the situation differs depending on whether the glass is placed inside, it is difficult to prevent the drop of the glass from degrading the fire resistance.

SUMMARY OF THE INVENTION It is an object of the present invention to provide fittings capable of preventing deterioration of fire resistance due to dropout of glass having high fire resistance strength.

In order to achieve the above object, the fitting according to the present invention includes a first shoji on one edge side in the prospective direction of the frame, and a second shoji on the other edge side of the frame. 2 shoji, said first shoji and said second shoji are fittings constructed by mounting a frame on the four sides of each of the facing materials, wherein the facing materials of said first shoji differ from each other in fire resistance strength. It is a multi-layered glass in which a plurality of sheets of glass are arranged facing each other, and the vertical frame serving as an arrangement in the first shoji has a hollow portion, and is a frame that constitutes the first shoji and the second shoji. is characterized in that a reinforcing member made of a material having a linear expansion coefficient smaller than that of the vertical stile is provided only in the hollow portion of the vertical stile that serves as a table in the first shoji.

According to this invention, since the reinforcing member is provided only in the hollow portion of the vertical frame serving as a meeting in the first shoji, compared to the case where the vertical frame of the second shoji is also provided with the reinforcing member. It becomes easy to control the deformation of the vertical frame of the first shoji. For example, by suppressing the deformation of the vertical frame of the first shoji, the glass with high fire resistance is prevented from falling off, and the fire resistance is lowered. can be prevented more reliably.

As is clear from the drawing, the thermally expandable member 50C has a vertical dimension larger than that of the air introduction hole 23e, and is disposed at a position that covers the entire length of the air introduction hole 23e in the vertical direction. . Although not shown in the figure, the respective thermally expansive members 50A, 50B, 50C are adhered with double-sided tape or adhesive, so that they will not come off from the inner shoji 20 inadvertently.

In the fittings configured as described above, when exposed to high temperatures due to a fire or the like, the sealing members 11c and 12c provided between the outer shoji 30 and the frame 10 and between the inner shoji 20 and the frame 10 , 14c, 14d, 22c, 26, and 37 are destroyed by fire. It is possible to prevent a situation in which a gap is formed between the inner shoji 20 and the frame body 10 and a gap is formed between the outer vertical frame 33 and the inner vertical frame 22 due to expansion of the expandable member 50.例文帳に追加. Moreover, the inner upper frame 24 and the upper frame 13 are connected to each other by the longitudinally continuous connecting piece 24c integral with the inner upper frame 24, so that the inner vertical frame 23 and the vertical frame 12 are connected to each other. The spaces between the upper frame 13 and the inner upper frame 13 are connected to each other by the guide wall portion 23a which is integral with the inner vertical frame 23 and which is continuous in the longitudinal direction. Even if the frame 24, the vertical frame 12, or the inner vertical frame 23 is thermally deformed, there is no risk of creating a gap that would cause a flame path between them, which is advantageous in terms of fire prevention.

Furthermore, in the fittings described above, an escape space 24X and a non-fixing space 24Y are secured between the inner upper frame 24 and the upper frame 13. As shown in FIG. Therefore, even if the inner vertical frame 22 is thermally stretched due to the influence of sunlight or the like, or if the intermediate portion of the upper frame 13 is bent downward due to aging, the escape space 24X and the unfixed These deformations are absorbed by the space 24Y. Therefore, during normal use, there is no concern that the inner vertical frame 22 of the inner shoji 20 will be bent in the out-of-plane direction. In addition, the thermally expandable members 50A and 50B of the inner upper frame 24 are arranged in the portions corresponding to the escape space 24X, the non-fixed space 24Y, and the door-end escape space 24Z, as described above. Therefore, in the event of thermal expansion, it is possible to reliably block the flame path generated by the escape space 24X, the non-fixed space 24Y, and the door-side escape space 24Z. There is no risk of causing the spread of fire.

Further, between the inner vertical frame 23 and the vertical frame 12, the two guide walls 23a are in contact with the projected surface of the vertical frame 12, thereby forming a space 60 surrounded on all four sides. Therefore, the thermally expansive member 50C arranged on the inner vertical frame 23 expands inside this limited space 60, creating a gap between the inner vertical frame 23 and the vertical frame 12. can be prevented more reliably. In addition, the thermal expansion member 50C provided on the inner vertical frame 23 is provided at a height position including the air introduction hole 23e. Therefore, when the fittings are exposed to high temperatures, the communication between the glass receiving groove 21d of the inner shoji 20 and the outside air through the air introduction hole 23e is interrupted by the thermally expanding member 50C. In other words, when the thermally expandable member 50C thermally expands, both ends of the space 60 formed between the inner vertical frame 23 and the vertical frame 12 are exposed even if the direct air introduction hole 23e is not closed. is blocked by the thermally expanded thermally expandable member 50C, the communication state between the glass accommodating groove 21d and the outside air is cut off. As a result, even if the spacer member 21a used as the face member 21 is melted and combustible gas is generated in the glass containing groove 21d, the gas will not leak to the outside, and there is no risk of causing a fire. .

Here, for example, when a fire breaks out outdoors and the outdoor-side portion of the fitting is exposed to high temperatures, the amount of thermal expansion of the outdoor-side becomes greater than that of the indoor-side. For this reason, as shown as a comparative example in the upper part of FIG. When the material is not provided, the outer vertical frame 33 of the outer shoji 30 and the inner vertical frame 22 of the inner shoji 20 are curved so as to gradually protrude toward the outside as the temperature of the fittings rises. As a result, when the temperature of the fittings reaches about 600° C., there is a concern that the wire glass 31b of the outer shoji 30 and the wire glass 21b of the inner shoji 20 may fall off from the frame. is not necessarily preferable.

On the other hand, in the fittings of the embodiment, the reinforcing member 27 is provided only on the outdoor side portion of the inner vertical frame 22 corresponding to the wired glass 21b. Therefore, as shown in the lower part of FIG. 7, even when the temperature of the fittings rises, the thermal expansion of the portion of the inner vertical frame 22 located on the outside of the room is suppressed by the reinforcing material 27 . As a result, the outer vertical frame 33 is connected to the inner vertical frame 22 by the crescent 22b and the crescent receiver 33b, and is restricted from moving away from the inner vertical frame 22 by the smoke returners 22a and 33a. Since there is no reinforcing material in the hollow interior, the inner vertical frame 22 is pulled toward the inner vertical frame 22, so that thermal deformation such as convexity toward the outside of the room is suppressed. As a result, even when the temperature reaches a high temperature of about 600° C., the outer vertical frame 33 and the inner vertical frame 22 are kept in such a state that the thermal deformation of the outer frame 33 and the inner vertical frame 22 is suppressed. Since there is no possibility that the glass 21b will fall off from the stile, it is advantageous in terms of fire prevention.

Incidentally, in the fittings in which the wire glass 31b, 21b with high fire resistance strength is arranged on the outdoor side in each of the outer shoji 30 and the inner shoji 20, when a fire breaks out in the room, as shown in FIG. Also in both of the fittings described above, the float glasses 31c, 21c with low fire resistance strength are thermally cracked at about 100.degree. However, since the edges of the float glasses 31c and 21c located in the glass receiving grooves 31d and 21d are kept in a state of being held by the frame, the wire glass 31b and 21b may drop off from the frame. never In particular, according to the fitting in which the face material supporting fitting 28 is provided in the glass receiving groove 21d as in the embodiment, the edge of the float glass 21c can be more reliably prevented from falling off from the stile. The action effect becomes more remarkable.

In the above-described embodiment, the reinforcement member 27 is provided only on the outdoor side of the inner vertical frame 22 of the inner shoji 20, but the present invention is not limited to this.

For example, as in Modification 1 shown in FIG. If the reinforcing member 27 is provided only on the outdoor side of the outer vertical frame 33, the same effects as those of the embodiment can be obtained.

On the other hand, in a fitting provided with the outer shoji 30 and the inner shoji 20 in which the wire glasses 31b, 21b with high fire resistance are placed on the indoor side, the outer vertical frame 33 The reinforcing member 27 may be provided only on the indoor side of the inner vertical frame 22, or, as shown in Modified Example 3 of FIG. do not have. In Modifications 1 to 3, the same reference numerals are assigned to the same configurations as in the embodiment.

Further, in the above-described embodiment and modified examples 1 to 3, the fixing structure between the inner shoji and the frame is described in detail, but these structures are not necessarily essential. In particular, in the present invention, it is not necessary to fix the inner shoji to the frame, and like the outer shoji, it may be arranged so as to be movable with respect to the frame. In this case, the outside shoji may be fixed to the frame.

Furthermore, although double glazing comprising wired glass and float glass is applied as the face material, the glass is not necessarily limited to these as long as it is a combination of glasses having different fire resistance strengths. Further, the reinforcing material does not have to be steel, and any material having a coefficient of linear expansion smaller than that of the stile may be used.

Furthermore, in the above-described embodiment, the reinforcing member is arranged at a position that is biased in the hollow portion of the vertical frame, but it is not necessarily limited to this. For example, regardless of the shape and size of the reinforcing material, it may be connected to the vertical frame by screw members only at the position corresponding to the glass with high fire resistance strength, or the center of gravity position may be changed so that the fire resistance strength is increased by changing the plate thickness. It may be configured to be in the lower position corresponding to high glass.
