Description

  The present invention relates to an improvement of a glass-equipped fitting including a rectangular frame-like frame and a glass panel fitted inside the frame, such as a glass shoji and a glass door. It aims to realize a structure that can achieve both drainage and fire prevention in the event of a fire.

  A window device is provided at the opening of the building frame for the purpose of lighting and ventilation. FIG. 21 shows an example of such a window device. The window device 1 includes a window frame 2 fixed to an opening of a building frame, and a pair of glass shojis 3a and 3b built in a sliding manner inside the window frame 2.

  Among them, the window frame 2 is arranged in the horizontal direction to form the upper side, the lower frame 5 is also arranged in the horizontal direction to form the lower side, and the vertical frame is arranged to define the left and right vertical sides. It consists of a pair of eaves frames 6 and 6 to be constructed, and is constructed in a rectangular frame shape by connecting the respective ends of these frames 4 to 6.

  Each said glass shoji 3a, 3b is comprised by inserting glass panel 8a, 8b inside rectangular frame-shaped collar frame body 7a, 7b. Each of the flange frames 7a and 7b is made of an integrally extruded material made of an aluminum alloy, and constitutes upper and lower ribs 9a and 9b constituting the upper side, lower collars 10a and 10b constituting the lower side, and left and right vertical sides. By connecting the respective end portions of the summoning rods 11a and 11b and the door toe rods 12a and 12b, which are rods, a rectangular frame shape is formed.

  Further, as shown in FIG. 22, the lower punch 10b (10a) constituting the glass shoji 3b (3a) is provided with a drain hole (drainage hole) 13 to support the lower side of the glass panel 8b (8a). Rainwater that has entered the glass groove 14 or condensed water generated on the glass surface on the indoor side of the glass panel 8b (8a) is discharged to the outside. In addition, the example of illustration has shown the case where the multilayer glass excellent in heat insulation and soundproofing is used as the glass panel 8b (8a).

However, in the case where the drain holes 13 for drainage are provided in the lower punches 10a and 10b constituting the glass shoji 3a and 3b, the following problems may occur unless some measures are taken.
For example, when a fire occurs in a building and the glass shoji 3a and 3b are exposed to flame or radiant heat, among the parts constituting the glass shoji 3a and 3b, they are arranged around the glass panels 8a and 8b. Resin parts, etc., which are often used, are melted by heat and may generate flammable gases. The flammable gas generated in this way may accumulate downward due to its own weight and may flow out of the room through the drain holes 13 of the lower rods 10a and 10b. Since the combustible gas has the property of being easily ignited, it is easy to cause a fire to spread by igniting the combustible gas flowing out of the room. In addition, there is a possibility that flames, hot air, etc. enter the building through the drain hole 13 or go out of the building. As described above, when a drain hole for drainage is provided in the lower jar, it is difficult to ensure sufficient fire resistance.

  In order to solve such a problem, it has begun to consider using a heated foam material that expands (expands) when heated to close the drain hole in the event of a fire. However, any of the structures proposed so far involves sticking a heated foam material in the vicinity of the drain hole with an adhesive, and it is inevitable that the reliability related to closing the drain hole is lowered. . The reason for this is that the heated foam material generally starts to foam at about 200 ° C., whereas the adhesive used for sticking starts to melt at a lower temperature (eg, about 120 ° C.). This is because there is a possibility that the adhesive melts before the foam starts to foam and the heated foam material peels off from the predetermined mounting position. Even when the heated foam material falls off from a predetermined position, the foamed heated foam material may block a part of the drain hole, but it is difficult to sufficiently close the drain hole. In addition, the glass shoji may be temporarily stored outdoors, such as at the construction site, before the glass is fitted, but in such a case, the heated foam is exposed to wind and rain. There is a possibility of peeling off from a predetermined position. Thus, it is inevitable that the reliability related to closing the drain hole is lowered only by attaching the heating foam material by sticking.

  As prior art documents disclosing the use of a heated foam material in order to improve the fire resistance of joinery, there are inventions described in Patent Documents 1 and 2, for example. Of these, Patent Document 1 uses a heated foam material in order to improve the fire resistance of the portion between the window frame and the window jar. Further, in the case of the invention described in Patent Document 2, a heating foam material is installed in the glass groove to prevent the glass groove from becoming a flow path of smoke or the like. However, in any of the inventions described in Patent Documents 1 and 2, the heating foam material is intended to be attached by sticking, and a heating foam attachment structure capable of solving the above-described problems is disclosed. It has not been.

  In view of the circumstances as described above, the present invention can secure drainage in normal times, and can effectively close the drainage hole in the event of a fire, thereby obtaining sufficient fire resistance. Invented to realize the above.

The joinery with glass of the present invention includes a gutter frame and a glass panel.
Of these, the eaves frame body is formed, for example, by connecting an upper eave, a lower eave, and a pair of left and right eaves in a rectangular frame shape, each made of an extruded aluminum material.
The glass panel is a single layer or a double layer glass, and is fitted inside the frame body.
Further, the lower frame constituting the frame body is drained (for example, penetrating in the vertical direction and indoor / outdoor direction) for draining moisture that has entered into the glass groove into which the lower side of the glass panel is inserted. A hole is provided.

  Particularly in the case of the glass-equipped fittings of the present invention, a plate-like shape (including a belt-like shape and a sheet-like shape) that foams at least in the plate thickness direction by heating in the lower space located below the glass groove in the lower heel. In this state, the heating foam material is attached to the lower arm in a state facing the drain hole through a gap in a direction corresponding to the plate thickness direction. It is fixed to the attachment by mechanical means such as screws or caulking.

Furthermore, in the case of the present invention, the mounting attachment is formed by bending a metal plate material having corrosion resistance. And, to this mounting attachment, the mounting plate portion for mounting to the lower arm, the fixed plate portion for fixing the heating foam material, the heat capacity of the mounting attachment is kept low, the temperature of the fixed plate portion There is a notch to make the rise early.

When implementing such a glass fitting of the present invention, for example, as in the invention described in claim 2 , a plurality of drain holes are provided in the lower arm in the vertical direction. And the said heating foam material is provided in the state which opposes at least 1 drain hole among these several drain holes.
Further, when carrying out the invention described in claim 2 as described above, for example, as in the invention described in claim 3 , the heating foam material is placed at the bottom of the plurality of drain holes. It is provided in a state facing only the drain hole located.
Further, when carrying out the invention described in claim 3 , for example, as in the invention described in claim 4 , the heating foam is fixed to the lower surface of the attachment attachment, and the outermost It is located above the drain hole located in the lower part.

Furthermore, when carrying out the present invention, as in the invention described in claim 5 , for example, the glass panel is formed by arranging a plurality of glass plates in parallel with each other at a predetermined interval. A layer glass is used.

According to the glass-equipped fitting of the present invention having the above-described configuration, it is possible to ensure the drainage performance of the drain hole in normal times, and to effectively block the drain hole with the foamed heating foam material in the event of a fire. Can get enough fire protection.
That is, in the case of the present invention, at least a plate-like heating foam material that foams in the thickness direction is opposed to the drain hole through a gap in a direction that coincides with this thickness direction. Therefore, the drainage can be secured satisfactorily.
In the case of the present invention, the heating foam material is fixed to the attachment attached to the lower arm by mechanical means such as screws and caulking. For this reason, it is possible to effectively prevent the heated foam material from dropping before foaming, as in the case where the heated foam material is attached only by sticking. Further, even when the glass fitting is temporarily stored outdoors and exposed to wind and rain, it is possible to effectively prevent the heated foam from falling off for the same reason. Therefore, according to the present invention, it is possible to foam the heated foam material at the intended mounting position in the event of a fire. Furthermore, since the water drain hole is arranged in the foaming direction (plate thickness direction) of the heated foam material, a part of the foamed heat foam material can enter the inside of the water drain hole. As a result, it is possible to improve the reliability related to closing the drain hole with the heated foam material. And a drain hole can be effectively plugged up with a heating foam material, and sufficient fire prevention property is acquired.

[First example of embodiment]
1 to 8 show a first example of the embodiment of the present invention. This example shows a case where the present invention is applied to a glass shoji for a vertical sliding window. The window device 1a of this example includes a window frame 2a fixed to an opening of a building frame, and a glass shoji 3c attached to the inside of the window frame 2a so as to be freely opened and closed (slid out vertically). The glass shoji 3c is supported on the window frame 2a by a pair of upper and lower stays (not shown), and can be opened and closed based on a turning operation of an operating lever 15 provided on the indoor side.

  The window frame 2a is arranged in the horizontal direction to form the upper side, the lower frame 5a is also arranged in the horizontal direction to form the lower side, and is arranged in the vertical direction to form the left and right vertical sides. It consists of a pair of eaves frames 6a, 6a, and is constructed in a rectangular frame shape by connecting the respective ends of these frames 4a-6a. Each of these frames 4a to 6a is made of an integrally extruded material of aluminum alloy. In addition, in each of the frames 4a to 6a, the airtight pieces 16a to 16d are continuously arranged in four rounds at the same position in the indoor and outdoor directions (front and back direction in FIG. 1, left and right direction in FIG. 2, and vertical direction in FIG. 3). I support it. These airtight pieces 16a to 16d are elastically sandwiched between the glass screen 3c (the frame 7c) and the window frame 2a in a closed state of the glass screen 3c.

  The glass shoji 3c is configured by fitting a glass panel 8c inside a rectangular frame-shaped eaves frame 7c. Of these, the frame 7c is made of an integrally extruded material made of an aluminum alloy. The upper frame 9c forms the upper side, the lower frame 10c forms the lower side, and a pair of left and right vertical sides. By connecting the end portions of the flanges 17 and 17, a rectangular frame shape is formed.

  The glass panel 8c is a multi-layer glass, and two glass plates 19a and 19b arranged in parallel with each other at a predetermined interval with a spacer 18 between the two glass plates 19a and 19b. The intermediate layer 20 is composed of an intermediate layer 20 and a sealing material 21 that seals the peripheral edge of the intermediate layer 20 (around the spacer 18). In the illustrated example, among the glass plates 19a and 19b, the glass plate 19a disposed on the outdoor side is a glass with excellent fireproof performance. The intermediate layer 20 is filled with an inert gas such as sulfur hexafluoride gas, argon gas, or krypton gas in consideration of heat insulation performance.

  The upper side (upper edge part), the lower side (lower edge part), and the side side (side edge part) of the glass panel 8c are the upper side 9c, the lower side 10c, and the left and right sides constituting the side frame 7c. Inserted into the glass grooves 22a to 22c provided in the flanges 17 and 17, respectively. Further, the lower side of the glass panel 8c is abutted against the groove bottom plate portion 24 of the glass groove 22b provided in the lower rod 10c via the setting block 23, and both sides of the glass panel 8c Spacer blocks 25, 25 are fitted between the glass bottoms 24 a, 24 a of the glass grooves 22 c, 22 c provided on the both sides 17, 17, respectively. Moreover, the outer side sealing material 26a and the indoor side sealing material 26b are arranged on the entire circumference between both side surfaces near the outer peripheral edge of the glass panel 8a and the openings of the glass grooves 22a to 22c. The seal is sealed. It should be noted that a glazing channel 27 as shown in FIG. 22 may be used in place of the outdoor side and indoor side sealing materials 26a and 26b.

  Further, the lower rod 10c is provided with a plurality of drain holes 28, 28a penetrating in the vertical direction, and is generated in rain water entering the glass groove 22b or on the indoor side glass surface of the indoor side glass plate 19b. Condensed water etc. is discharged outside the room. In the case of this example, a total of three drain holes 28, 28a are formed in the lower rod 10c. Of these, the two drain holes 28, 28 are formed near the longitudinal ends of the groove bottom plate portion 24 of the glass groove 22b, and the remaining one drain hole 28a is formed on the lower rib 10c. Of the bottom plate portion 29 constituting the lower surface, the bottom plate portion 29 is formed in a portion located below one drain hole 28. Each of the drain holes 28, 28a has an oval shape, but a circular shape, an oval shape, or other shapes may be adopted.

  In particular, in the case of this example, when a fire occurs, resin parts or the like disposed around the glass panel 8c (for example, the spacer 18, the sealing material 21, the setting block 23, the spacer block 25, the sealing materials 26a and 26b). ) Is dissolved to generate a flammable gas, the flammable gas is prevented from flowing out of the room through the drain holes 28 and 28a, and a flame, hot air, etc. In order to prevent entering into the building through the holes 28, 28a or going out of the building, the heating foam material 30 is installed in the lower casing 10c.

  The heating foam material 30 used in this example is a plate shape (strip shape, sheet shape) with a thickness of about several millimeters, and is sufficient if it is foamed (expanded) at least in the plate thickness direction by heating and has fire resistance. For example, the trade name “Fibro” manufactured by Sekisui Chemical Co., Ltd. can be used. “Fibro” has a foaming start temperature of about 200 ° C., and the plate thickness increases to about 5 to 40 times depending on the type (butyl type, epoxy type, etc.). In the case of this example, the heating foam material 30 having such a configuration (characteristics) is placed in a space below the glass groove 22b of the lower rod 10c (a lower space separated from the glass groove 22b by the groove bottom plate portion 24). It is arrange | positioned in the hollow accommodating part 31 which is. And the said heating foam material 30 is located above the drain hole 28a provided in the lowest part among the said drain holes 28 and 28a. More specifically, the lower surface of the heating foam material 30 is opposed to the drain hole 28a via a vertical gap 32 that coincides with the thickness direction of the heating foam material 30. The smaller the size of the gap 32, the higher the density of the heated foamed material 30 in the foamed state, and it is possible to effectively close the drain hole 28a. It is necessary to secure a certain size from the aspect of ensuring the water, considering at least the surface tension of water. Therefore, in the case of this example, the size of the gap 32 is determined so that both the drainage performance in normal times and the closing performance of the drain hole 28a in the event of a fire are compatible (specifically). Specifically, it is about 5 to 10 mm).

  In the case of this example, in order to arrange the heating foam material 30 at the position as described above, a mounting attachment 33 as shown in FIGS. 7 and 8 is used. The mounting attachment 33 is formed by punching and bending a metal plate material having corrosion resistance and heat resistance such as stainless steel, and includes a fixed plate portion 34, a substrate portion 35, a mounting plate portion 36, 1 It has a pair of notches 37, 37.

  Of these, the fixed plate portion 34 is a portion for fixing the heating foam material 30. In this example, the fixed plate portion 34 is provided in parallel to the bottom plate portion 29, and screw holes are provided at both ends in the longitudinal direction. 38, 38 are formed. The board portion 35 has an inverted T-shape when viewed from the front, and includes an upper half narrow portion 39 and a lower half wide portion 40, and an indoor side end portion of the fixed plate portion 34. It is formed in a state of being bent at a right angle from the top to the top. The mounting plate portion 36 is a portion for attaching the mounting attachment 33 to the lower collar 10c, and is bent at a right angle from the upper end portion of the substrate portion 35 (the narrow portion 39) toward the outdoor side. The screw hole 38a is formed in the center part. Further, each of the notches 37 and 37 is a portion that keeps the heat capacity of the attachment attachment 33 low and allows the temperature of the fixed plate portion 34 (and thus the heating foam material 30) to rise quickly, and the substrate portion. It is formed on both side portions of the narrow portion 39 that constitutes 35. In the case of this example, the length dimension and the width dimension of the fixed plate portion 34 are the same as the length dimension and the width dimension of the heating foam material 30. Further, the length dimension and the width dimension of the heating foam material 30 and the fixed plate portion 34 are made larger than the length dimension and the width dimension of the drain hole 28a, respectively.

  In particular, in the case of this example, the heating foam material 30 is screwed and fixed to the fixed plate portion 34 constituting the attachment attachment 33. Specifically, with the upper surface of the heating foam material 30 in contact with the lower surface of the fixed plate portion 34, the fixing screw inserted through the mounting holes 41, 41 formed in the heating foam material 30 from below. The heating foam material 30 is mechanically fixed to the fixed plate portion 34 by screwing 42 and 42 into screw holes 38 and 38 formed in the fixed plate portion 34 and further tightening. .

  Then, the mounting attachment 33 is coupled and fixed to the lower collar 10c in a state where the heating foam material 30 is screwed and fixed in this manner. Specifically, with the upper surface of the mounting plate portion 36 in contact with the lower surface of the groove bottom plate portion 24 of the glass groove 22b, the mounting is made by inserting the through hole 43 formed in the groove bottom plate portion 24 from above. The mounting attachment 33 is suspended and fixed to the groove bottom plate portion 24 of the lower rod 10c by screwing a screw 44 into a screw hole 38a formed in the mounting plate portion 36 and further tightening. And in such an attached state, the lower surface of the heating foam material 30 is opposed to the drain hole 28a through a vertical gap 32 that coincides with the thickness direction of the heating foam material 30. . In the case of this example, the dimension (size) of the gap 32 in the vertical direction is constant over the longitudinal direction and the short direction of the heating foam material 30, and the lower surface of the heating foam material 30 and the water. Although the hole 28a is arranged in parallel, when carrying out the present invention, the heating foam and the water hole may be arranged non-parallel without making the size of the gap constant ( May be diagonally opposed).

In the case of this example having the above-described configuration, it is possible to ensure drainage in normal times, and in the event of a fire, the water drainage hole 28a can be effectively blocked by the foamed heating foam material 30, Sufficient fire resistance can be obtained.
That is, in the case of this example, at least the plate-shaped heating foam material 30 that foams in the thickness direction is opposed to the drain hole 28a through the vertical gap 32 that coincides with the thickness direction. In normal times, a gap 32 having a size in consideration of drainage exists between the lower surface of the heating foam 30 and the upper surface of the bottom plate portion 29. For this reason, it is possible to ensure good drainage in normal times.

  In the case of this example, the heating foam material 30 is fixed to the attachment 33 attached to the lower collar 10c by mechanical means using fixing screws 42 and 42. For this reason, it is possible to effectively prevent the heated foaming material 30 from dropping before foaming, as in the case where the heating foam 30 is attached only by sticking with an adhesive. Further, even when the glass shoji 3c is temporarily stored outdoors and exposed to wind and rain, it is possible to effectively prevent the heating foam material 30 from falling off for the same reason. Therefore, in the case of this example, it is possible to foam the heating foam material 30 at the intended mounting position (position as designed) when a fire occurs. Further, since the drain hole 28a is arranged in the foaming direction (plate thickness direction) of the heated foam material 30, the state after foaming is shown in FIG. 4 (B) and FIG. 5 (B). As shown in the figure, a part of the heating foam material 30 can enter the inside of the drain hole 28a. As a result, it is possible to improve the reliability related to closing the drain hole 28a by the heating foam material 30. And the water draining hole 28a can be effectively blocked by the heating foam material 30, and sufficient fire resistance can be obtained.

  Further, in the event of a fire, the heated foaming material 30 closes the drain hole 28a provided below, so that only the drain hole 28 provided above is closed. The amount of outflow can be reduced. That is, when closing the drain hole 28a provided below, in the state before the foamed heating material 30 is foamed, flammable gas or the like can be kept in the storage portion 31 to some extent, The amount of the heated foam material 30 flowing out from the drain hole 28a before foaming can be suppressed to a small amount. On the other hand, when the drain hole 28 provided in the upper portion is closed, the drain hole 28 is blown before foaming. This is because the combustible gas or the like that has passed through is discharged outside the room without being prevented from flowing out.

  Further, in the case of this example, since the mounting attachment 33 for fixing the heating foam material 30 is provided with notches 37, 37, the heat capacity of the mounting attachment 33 can be kept low, and the fixed plate portion The temperature of 34 (and thus the heated foam material 30) can be increased quickly. For this reason, in the event of a fire, the heated foaming material 30 can be foamed early to immediately close the drain hole 28a. Accordingly, it is possible to effectively prevent flammable gas from flowing out of the room, and it is also effective for flames, hot air, etc. to enter or leave the building through the drain holes 28a. Can be prevented.

[Second Example of Embodiment]
FIG. 9 shows a second example of the embodiment of the present invention. The feature of this example is that the shape of the attachment 33a is devised (the range of the notch is expanded) in order to foam the heated foam material 30 (see FIGS. 2, 4, 5 and the like) earlier. Since the configuration and operational effects of the other parts are the same as in the case of the first example of the above-described embodiment, overlapping explanations and illustrations are omitted, and the following description will focus on the characteristic parts of this example. To do.

  In the case of the attachment 33a of this example, the width dimension of the substrate portion 35a is constant over the vertical direction (the entire width is narrow), and not only the both side portions of the upper half portion of the substrate portion 35a but also the lower half portion. Notches 37a and 37a are formed in a range extending over both sides of the part.

In the case of this example having the above-described configuration, the heat capacity of the mounting attachment 33a can be suppressed lower than in the case of the first example of the embodiment, so that the heating foam material 30 is foamed more quickly. I can do things.
About another structure and an effect, it is the same as that of the case of the 1st example of the said embodiment.

[Third example of embodiment]
10 to 12 show a third example of the embodiment of the present invention. The feature of this example is that the two drain holes 28, 28a provided in the vertical direction are closed. Since the configuration and operational effects of the other parts are the same as those of the first example of the above-described embodiment, overlapping description and illustration will be omitted, and the following description will focus on the characteristic parts of this example.

  The mounting attachment 33b used in this example is smaller in the vertical dimension of the narrow part 39a of the substrate part 35b than the mounting attachment 33 of the first example of the above embodiment, and the vertical dimension of the wide part 40a. Has increased. Further, the pair of horizontal plate portions 45, 45 are formed in a state of being bent at a right angle from the upper end portion of the wide portion 40a toward the outdoor side.

  And the heating foam material 30a is adhere | attached on the upper surface of one horizontal board part 45 located under the drain hole 28 formed in the groove bottom board part 24 of the lower collar 10c among both the said horizontal board parts 45 and 45. It is affixed with an agent. Thereby, the upper surface of this heating foam material 30a is made to oppose with respect to the said drain hole 28 through the up-down direction clearance 32a which corresponds to the plate | board thickness direction of this heating foam material 30a. For the lower drain hole 28a formed in the bottom plate portion 29 of the lower rod 10c, as in the case of the first example of the above embodiment, the fixed plate portion constituting the mounting attachment 33b. The heating foam 30 is mechanically fixed to the lower surface of 34 by fixing screws 42, 42. And the lower surface of this heating foam material 30 is made to oppose the said drain hole 28a through the clearance 32 of the up-down direction which corresponds to the plate | board thickness direction of this heating foam material 30. FIG.

  In the case of this example having the above-described configuration, when a fire occurs, not only the drain hole 28a positioned below but also the drain hole 28 positioned above the drain hole 28a can be closed. For this reason, it is possible to more effectively prevent flammable gas and the like from flowing out of the room, and flames and hot air enter or leave the building through the drain holes 28 and 28a. Things can be effectively prevented. Further, when carrying out this example, a structure that is mechanically fixed to the one horizontal plate portion 45 is adopted even for the heating foam material 30a for closing the drain hole 28 located above. Also good.

[Fourth Example of Embodiment]
13 to 20 show a fourth example of the embodiment of the present invention. In this example, the present invention is applied to a glass door for a door. The door device 46 of this example includes a door frame 47 fixed to the opening of the building frame, and a glass door 48 attached to the inside of the door frame 47 so as to be opened and closed. The glass door 48 is supported on the door frame 47 by a plurality of hinges 49 arranged in the vertical direction, and can be opened and closed based on a turning operation of a door knob 50 provided on each of the indoor side and the outdoor side. Yes.

  In the case of this example, the heating foam material 30 is attached to the lower collar 10d constituting the glass door 48 using the attachment attachment 51. Although there is a difference depending on the use for the door and for the window, the basic structure of the door frame 47 and the glass door 48 is the same as the window frame 2a and the glass shoji 3c in the first example. Equivalent parts are denoted by the same reference numerals, and redundant description is omitted.

  In the case of this example, a total of four drain holes 28b, 28c penetrating in the vertical direction are formed in the lower rod 10d. Two of these drain holes 28b are formed at both ends in the longitudinal direction of the groove bottom plate portion 24b of the glass groove 22d, and the remaining two drain holes 28c constitute the lower surface of the lower collar 10d. The bottom plate portion 29a is formed near the both ends in the longitudinal direction. In the case of this example, the drain hole 28c located below is formed by cutting out a part of the tapping hole 52 erected on the upper surface of the bottom plate portion 29a. The drain hole 28b provided at the upper side is rectangular, and the drain hole 28c provided at the lower side is oval.

  Also in the case of this example, the heating foam material 30 is installed in a space below the glass groove 22d in the lower rod 10d so as to block only the drain hole 28c disposed below. For this purpose, the heating foam material 30 is positioned above the drain hole 28c, and the lower surface of the heating foam material 30 is aligned with the drain hole 28c in the thickness direction of the heating foam material 30. It is made to oppose via the clearance 32b of the up-down direction.

  In the case of this example, in order to arrange the heating foam material 30 at the position as described above, an attachment attachment 51 as shown in FIGS. 19 and 20 is used. The mounting attachment 51 is formed by punching and bending a metal plate having corrosion resistance and heat resistance such as stainless steel, and includes a fixed plate portion 53, four leg portions 54, 54, and a pair. Notches 55, 55 and a pair of mounting plate portions 56, 56.

  Of these, the fixed plate portion 53 is a portion for fixing the heating foam material 30 and is provided in parallel with the bottom plate portion 29a, and screw holes 57 and 57 are respectively formed at both ends in the longitudinal direction. ing. Each of the leg portions 54, 54 is formed in a state of being bent at right angles from both ends of the long side of the fixed plate portion 53 toward the lower side, and the lower end edge of each leg portion 54, 54 is formed on the bottom plate portion 29a. It is in contact with the top surface. The notches 55 and 55 keep the heat capacity of the attachment attachment 51 low, and cause the temperature of the fixed plate portion 53 (and thus the heated foam material 30) to rise quickly, and for drainage. It is a part used as a channel | path, and is formed in the part between one pair of leg parts 54 and 54 arrange | positioned in a longitudinal direction, respectively. Further, each of the mounting plate portions 56, 56 is a portion for mounting the mounting attachment 51 to the lower collar 10d, and is a pair of the four leg portions 54, 54 disposed on the indoor side. The leg portions 54 and 54 are bent at right angles from the lower end portion toward the indoor side, and screw holes 57a and 57a are formed in the center portions of the leg portions 54 and 54, respectively. In the case of this example, the space between the pair of leg portions 54, 54 arranged in the short direction (indoor / outdoor direction) of the attachment attachment 51 also serves as a passage for drainage.

  In particular, in the case of this example, the heating foam material 30 is fixed to the fixed plate portion 53 constituting the attachment attachment 51 with screws. Specifically, in a state where the upper surface of the heating foam material 30 is brought into contact with the lower surface of the fixed plate portion 53, the fixing holes 58 and 58 formed in the heating foam material 30 are inserted from below. The heating foam 30 is mechanically fixed to the fixed plate portion 53 by screwing screws 59 and 59 into screw holes 57 and 57 formed in the fixed plate portion 53 and further tightening. Yes.

  Then, with the heating foam material 30 screwed and fixed in this manner, the attachment attachment 51 is coupled and fixed to the lower collar 10d. Specifically, with the lower surface of each mounting plate portion 56, 56 in contact with the upper surface of the bottom plate portion 29a, the mounting is inserted from below into the through holes 60, 60 formed in the bottom plate portion 29a. The mounting attachment 51 is coupled and fixed to the bottom plate portion 29a of the lower rod 10d by screwing screws 61, 61 into screw holes 57a, 57a formed in the mounting plate portions 56, 56 and further tightening them. ing. And in such an attachment state, the lower surface of the heating foam material 30 is opposed to the drain hole 28c via a vertical gap 32b that coincides with the thickness direction of the heating foam material 30. . If the supporting attachment 51 has a sufficient supporting rigidity with respect to the lower collar 10d, the outdoor side of the four legs 54, 54 is used to increase the temperature of the heating foam 30 more quickly. The pair of legs 54 can be omitted.

Even in the case of this example having the above-described configuration, it is possible to ensure drainage in normal times, and in the event of a fire, the water drainage hole 28c can be effectively blocked by the foamed heating foam material 30, Sufficient fire resistance can be obtained.
That is, in the case of this example, at least the plate-shaped heating foam material 30 that foams in the plate thickness direction is opposed to the drain hole 28c through the vertical gap 32b that coincides with the plate thickness direction. In normal times, a gap 32b having a size in consideration of drainage exists between the lower surface of the heating foam 30 and the upper surface of the bottom plate portion 29a. For this reason, it is possible to ensure good drainage in normal times.

  In the case of this example, the heating foam material 30 is fixed to the attachment 51 attached to the lower rod 10d by mechanical means using fixing screws 59, 59. For this reason, it is possible to effectively prevent the heated foaming material 30 from dropping before foaming, as in the case where the heating foam 30 is attached only by sticking with an adhesive. Further, even when the glass door 48 is temporarily stored outdoors and exposed to wind and rain, it is possible to effectively prevent the heating foam material 30 from falling off for the same reason. Therefore, in the case of this example, it is possible to foam the heating foam material 30 at the intended mounting position (position as designed) when a fire occurs. Further, since the drain hole 28c is arranged in the foaming direction (plate thickness direction) of the heated foam material 30, the state after foaming is shown in FIG. 16 (B) and FIG. 17 (B). As shown by the above, a part of the heating foam material 30 can enter the inside of the drain hole 28c. As a result, it is possible to improve the reliability related to closing the drain hole 28c by the heating foam material 30. And the drain hole 28c can be effectively plugged by the heating foam material 30, and sufficient fire resistance can be obtained.

Furthermore, when the glass door 48 is exposed to flame or radiant heat, the heat can be transmitted to the heating foam material 30 through the notches 55 and 55 provided in the attachment attachment 51. For this reason, compared with the case where these notches 55 and 55 are not provided, this heating foam material 30 can be foamed at an early stage.
