Description

  The present invention relates to a composite joinery in which a shoji is placed in a frame provided at an opening of a housing, for example.

Conventionally, a heating foam material is fixed to a metal frame in a vertical extension window or sliding window in which a shoji is placed in a frame body including a metal frame such as an aluminum alloy and a resin frame. In the event of a fire or the like, the heated foam material expands and foams due to hot air or the heat of a flame to fill the indoor / outdoor space, thereby delaying or suppressing the spread of the fire to the indoor / outdoor.
For example, in the vertical extension window described in Patent Document 1, a heating foam is attached and fixed by caulking to a metal rising portion that rises from the metal lower frame between the metal lower frame and the lower arm of the shoji. When the fire breaks out, the shoji and the window frame are deformed, and when hot air or flame enters the gap between the lower arm of the shoji and the lower frame from outside, the heating foam expands and blocks the hot air and flame. Fire spread to the inside is prevented and fireproofing can be improved.

Moreover, it is preferable that the heating foam material is installed indoors from the shoji.
Since the heating foam attached to the resin member such as the resin frame is installed on the indoor side from the shoji, the distance between the shoji and the frame is large, and the resin member and the heating foam are hot air or flame in the event of a fire from the outdoor side. Not easily affected.

Moreover, the heating foam material may be installed between the metal lower frame and the lower arm of the shoji.
ADVANTAGE OF THE INVENTION According to this invention, the space between a metal lower frame and the lower arm of a shoji can be sealed by thermal expansion of a heating foam material, and it can suppress that a flame and smoke distribute | circulate indoors and outdoors.

  According to the composite joinery according to the present invention, even when the resin member provided on the metal lower frame is exposed to a high temperature in the event of a fire or the like, it can be held so that it does not melt and collapse until the foamed foam expands and expands. Can prevent fire spread and increase fire resistance. In addition, since the heating foam material is attached to the resin member provided on the metal lower frame, it is not necessary to extend the metal lower frame or the like to the installation position of the heating foam material, and the attachment is simple and low cost.

It is a principal part longitudinal cross-sectional view which shows the arrangement | positioning structure of the lower frame and shoji of the vertical window by embodiment of this invention. It is an expanded sectional view of the heating foaming material installed between the lower frame and shoji shown in FIG.

Hereinafter, a vertical window as an example of a composite joinery according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2.
The vertical extending window 1 according to the embodiment shown in FIG. 1 is composed of a composite fitting made of a metal such as an aluminum alloy and resin. In the vertical window 1, a frame body 5 in which an upper frame and a lower frame 3 made of an aluminum alloy and a resin and left and right vertical frames 4 are formed in a rectangular frame shape is attached to an opening 2 of the housing. In the frame 5, a metal frame provided on the outdoor side and a resin frame provided on the indoor side are engaged with each other.
The shoji 7 that can be opened and closed in the frame 5 has an upper and lower collar 21 made of an aluminum alloy and a resin, and left and right vertical collars, and a double-layer glass or the like, for example. The glass panel 9 which becomes becomes. The suspension base of the shoji 7 is provided in the vicinity of one end of the frame 5 in the direction of finding, and its axis extends in the vertical direction and is supported by an upper frame and a lower frame 3 (not shown).

  In the frame 5 shown in FIG. 2, a metal lower frame 11 made of, for example, an aluminum alloy of the lower frame 3 extends from the outdoor side to the indoor side in a cross-sectional view. The lower lower frame 11 a of the metal lower frame 11 extends from the outdoor side to the indoor side along the opening 2, and a bent portion 11 aa bent downward in the middle is fixed to the housing with a fixing screw 10. The upper lower frame 11b formed on the upper side of the lower lower frame 11a is formed in a substantially stepped shape from the outdoor side toward the indoor side, and a drain hole 11c is formed in the lower part on the outdoor side.

  A stepped portion of the upper lower frame 11b forms a first step portion 11ba and a second step portion 11bb via a step, and a resin lower frame 12 having a plurality of hollow portions attached to the second step portion 11bb. It has been. The resin lower frame 12 has a base portion 12b having a tip claw portion 12a locked to a claw portion 14 having a substantially L-shaped cross section provided in the second step portion 11bb, and a rising portion 12c rising up. Yes. The rising portion 12c of the resin lower frame 12 is formed with a receiving portion 17 as a holder for holding the heated foam material 16, and the heated foam material 16 is inserted into the receiving portion 17 from the side and fixed by caulking the receiving portion 17, for example. Has been.

  Here, the heated foam material 16 is made of a known material, and is made of a material that is flame retardant and expands and foams to increase its volume when heated to a predetermined temperature. The expansion start temperature is not particularly limited, but is preferably about 150 ° C., for example, in accordance with the building standard method and the heating curve of the same construction ordinance. The expansion ratio is not particularly limited, but is preferably 10 to 40 times. The material of the heating foam material 16 is not particularly limited as long as it has such a performance. For example, it contains a thermal foam such as graphite or carbon fiber, and the base material is an epoxy resin, a polyvinyl chloride resin, The thing using butyl rubber etc. can be mentioned.

  Conventionally, as a member for supporting the heating foam material 16, since the resin is weak against heat and melts and collapses in a relatively short time compared to a metal member such as an aluminum alloy or stainless steel, a metal member having high heat resistance is used. . However, as a result of research by the present inventors, the temperature of the upper frame and the upper edge of the shoji 7 becomes relatively high during a fire or the like, so that the resin member dissolves before the expansion foaming of the heating foam material 16. However, it is found that the resin member can be held without melting until the heated foam material 16 expands and foams in order to maintain a relatively low temperature in the lower frame 3 or between the lower frame 3 and the lower collar 21 of the shoji 7. It was. For example, since the resin member remains undissolved in the range of 200 ° C. to 300 ° C. for about 18 minutes to 19 minutes when a fire occurs, the resin member remains until the heated foam material 16 expands and foams even when exposed to hot air or a flame. It was found to remain in the startup state.

Therefore, in the embodiment of the present invention, the heated foam material 16 is held by the resin lower frame 12 of the lower frame 3. In this case, it is more preferable to hold the heating foam 16 by providing the receiving portion 17 at the rising portion 12 c of the resin lower frame 12 that is close to the metal lower frame 11 and rises from the metal lower frame 11.
The upper end portion of the rising portion 12c is bent toward the shoji 7 side, and the first fin portion 18 made of an elastic member is installed at the tip so as to contact the shoji 7 that opens and closes. Moreover, the 2nd fin part 19 which consists of elastic members, such as rubber | gum, is attached to the outdoor side front-end | tip part of 1st step part 11ba.

The shoji 7 provided above the lower frame 3 houses a glass panel 9 made of double-glazed glass, for example, double-glazed glass, in a casing. The outdoor side glass 9a is made of, for example, netted glass and has a large thickness, and the indoor side glass 9b is set to be thinner than the outdoor side glass 9a. The lower casing 21 of the casing has a metallic lower casing 22 and a resin lower casing 23 provided on the indoor side. The metallic lower casing 22 has a substantially U-shaped cross section through the glass panel 9 through the glazing channel 24. It is supported by the support receiving portion 22a. The outdoor hanging part 22b of the metal lower rod 22 has a substantially L-shaped draining part 22c provided at the lower end while pressing and supporting one of the glazing channels 24 at the upper end. Moreover, the 2nd fin part 19 attached to the 1st step part 11ba of the metal lower frame 11 contact | abuts the draining part 22c, and prevents intrusion of rainwater etc.
Two-stage engagement receiving portions 22d and 22e located on the indoor side of the glass panel 9 are formed at the indoor side end portion of the metal lower collar 22, and the resin lower collar 23 is engaged with the engagement receiving portions 22d and 22e. Engaging claws 23a and 23b are formed. The resin lower rod 23 has a plurality of flow portions at the top and bottom, and a locking portion 23c for pressing and fixing the glazing channel 24 is formed on the outdoor side of the upper portion thereof. The first fin portion 18 formed at the upper end of the resin lower frame 12 is in contact with the resin lower collar 23 of the shoji 7 that opens and closes.

  A space K extending in the indoor / outdoor direction is formed between the metal lower frame 11 of the lower frame 3 and the metal lower cage 22 and the resin lower cage 23 of the shoji 7. The indoor side is sealed with the rising portion 12 c of the resin lower frame 12 rising from the metal lower frame 11 and the first fin portion 18. Moreover, the heating foam 16 is vertically held by the receiving portion 17 at the rising portion 12 c of the resin lower frame 12 facing the space K.

The vertical extension window 1 according to the present embodiment has the above-described configuration, and the operation thereof will be described next.
For example, when a fire occurs on the outdoor side of a building and the vertical window 1 is exposed to a high temperature, hot air is blown into the space between the shoji 7 and the upper frame or the space K between the shoji 7 and the lower frame 3. The flame is easy to flow in. On the upper frame side, since the space between the upper frame and the shoji 7 is relatively high temperature, the resin upper frame is easily melted by being exposed to high temperature, but the space K between the lower frame 3 and the shoji 7 has a relatively high temperature. Since it is low, the resin lower frame 12 does not melt immediately even if it is exposed to hot air or flame and is held on the metal lower frame 11 for a predetermined time. In particular, the rising portion 12c and the heating foam material 16 are located on the indoor side of the glass panel 9 of the shoji 7 so that they are not easily affected by hot air or flame, and the heating foam material 16 is melted by preventing falling or collapsing until expansion foaming. Can hold up without.
And before the rising part 12c of the resin lower frame 12 melt | dissolves at high temperature, the heating foam material 16 expands and foams, and seals the space K. FIG. This prevents hot air and flame from communicating inside and outside the vertical window 1 and prevents fire spread.

As described above, according to the vertical extending window 1 according to the present embodiment, even if the heating foam material 16 is provided on the rising portion 12c of the resin lower frame 12 in the lower frame 3, hot air or When exposed to a flame, the resin lower frame 12 does not dissolve until expansion foaming of the heating foam 16. Therefore, it is not necessary to extend the metal lower frame 11 or to install a metal piece for attaching the heating foam material 16 in order to fix the heating foam material 16, and the heating foam material 16 can be attached easily and inexpensively.
In addition, the rising portion 12c of the resin lower frame 12 to which the heating foam material 16 is attached is raised from the metal lower frame 11 and installed on the indoor side of the shoji 7, so that hot air, flame, etc. are difficult to reach. 12 is difficult to dissolve.

  In addition, the attachment structure of the heating foam material 16 of the vertical window 1 according to the present invention is not limited to the above-described embodiment, and appropriate changes and substitutions can be made without departing from the gist of the present invention. is there. In the following, modifications and the like of the present invention will be described, but the same or similar parts and components as those described in the above-described embodiments will be described using the same reference numerals.

In the above-described embodiment, the heating foam material 16 is attached to the rising portion 12c of the resin lower frame 12 in a vertical position standing up in a substantially vertical direction. However, the heating foam material 16 may be installed horizontally or obliquely attached in a horizontal direction. The orientation and posture of the are arbitrary.
Moreover, it is preferable to install the heating foam material 16 in the space K between the metal lower frame 11 and the lower gutter 21 in which the hot air and flame easily circulate indoors and outdoors in the lower frame 3. However, the attachment position of the heating foam material 16 in the region of the lower frame 3 according to the present invention does not necessarily have to be the space K between the lower frame 3 and the lower collar 21 of the shoji 7. For example, it may be attached to the resin lower frame 12 or the resin lower rod 23 within the lower frame 3 or the lower rod 21, and at that time, a resin member other than the resin lower frame 12 or the resin lower rod 23 may be provided and attached. Good. The resin lower frame 12 and the resin lower collar 23 are also included in the resin member of the present invention.

Further, the heating foam 16 and the rising portion 12c of the resin lower frame 12 do not have to be installed on the indoor side of the shoji 7 and may be, for example, the lower side of the lower arm 21 of the shoji 7 or the like.
In addition, although the above-mentioned embodiment demonstrated the case where a fire occurred on the outdoor side, this invention is applicable also when a fire occurs on the indoor side.
Further, the vertical window 1 has been described as an example of the composite fitting according to the present invention. However, the present invention is not limited to this, and the horizontal window, the sliding window, the FIX window, the continuous window, the single window, etc. It can be applied to various composite joinery.
