Description

The present invention relates to a heating and foaming method, in which a frame member constituting a rectangular frame arranged in an opening of a building and a stile member constituting a door body built inside the frame are foamed by heating. A heated foam fixture for attaching materials.

In the case of fittings that are built into a frame such as a window frame or door frame that is fixed to the opening of the building, and a door such as a window shoji or door, in the event of a fire, the space between the frame and the door will be There is a possibility that the gaps between them may become paths for flames, hot air, etc. Therefore, conventionally, it has been considered to close the gap between the frame and the door by using a heating foam material that foams (expands) when heated (for example, Japanese Utility Model Laid-Open No. 60-76942). Gazette).

The thermally foamed material is generally formed in a plate-like (sheet-like) shape, and is attached to the frame material that constitutes the frame or the frame material that constitutes the door using an adhesive tape or an adhesive. . However, heat-foaming materials generally begin to foam at about 200°C, whereas adhesives (including adhesives) used in adhesive tapes begin to melt at a lower temperature (for example, about 120°C). . For this reason, the adhesive melts before the heat-foaming material begins to foam, and the heat-foaming material may peel off from the predetermined attachment position.

In view of the circumstances as described above, for example, as shown in FIG. It is conceivable to use it instead of sticking or in combination with sticking. By adopting such a structure, it is possible to prevent the heated foam material 100 from falling off from the attached member 101 before being foamed. However, the structure for locking the heating foam material 100 in the groove 102 requires that the member to be attached 101 to which the heating foam material 100 is to be attached has the groove 102 in advance. For this reason, it is difficult to employ the thermally foamed material when attaching it to existing fittings. Further, a pair of plate-like pieces 103 forming the groove 102 are present over the entire length of the heating foam material 100 in front of the foaming direction of the heating foam material 100 (direction of arrow α in FIG. 20). For this reason, the pair of plate-like pieces 103 may interfere with the foaming of the heating foam material 100, which may be disadvantageous in closing the gap between the frame and the door.

[Structure of glass shoji 3]
The glass shoji 3 built inside the window frame 2 is constructed by fitting a glass panel 26 inside a rectangular stile frame body 25, as shown in FIG. The frame body 25 connects the ends of an upper frame 27 that forms the upper side, a lower frame 28 that forms the lower side, and a pair of vertical frames 29 that form the left and right vertical sides. It has a rectangular shape. Each of the stiles 27 to 29 forming the stile frame body 25 is an integrally extruded aluminum alloy material.

The glass panel 26 is a multi-layered glass as shown in FIGS. , 31b, and a sealing material 33 for sealing the periphery of the intermediate layer 32 (surrounding the spacer 30). In the illustrated example, the glass plate 31a arranged on the outdoor side is wire glass having excellent fireproof performance. In addition, the intermediate layer 32 is filled with an inert gas such as sulfur hexafluoride gas, argon gas, or krypton gas in consideration of heat insulation performance.

The upper edge (upper edge), the lower edge (lower edge), and the side edge (side edge) of the glass panel 26 are the upper stile 27, the lower stile 28, and the left and right vertical stiles that constitute the stile frame body 25. 29 are respectively inserted into the glass grooves 34a to 34c provided in the glass grooves 34a to 34c. In addition, the lower side of the glass panel 26 is abutted against the bottom of the glass groove 34b provided in the lower frame 28 via the setting block 35. Spacer blocks 36 are fitted between the bottoms of the glass grooves 34c. Both side surfaces of the glass panel 26 near the outer periphery and the openings of the glass grooves 34a to 34c are sealed over the entire periphery with the outdoor side sealing material 37a and the indoor side sealing material 37b, respectively. there is

[Support structure and opening/closing structure of glass shoji 3]
The glass shoji 3 is supported on the window frame 2 by a pair of upper and lower stays 38 (see FIG. 2) so that it can be opened and closed. The stay 38 is a link mechanism in which a plurality of metal plates are slidably and rotatably connected to each other. and the upper surface of the lower frame 5, respectively. The illustration of the stay 38 arranged between the upper frame 27 and the upper frame 4 is omitted.

The glass shoji 3 supported by the stay 38 inside the window frame 2 tends to tilt downward on the door tip side (left side in FIG. 1) due to its own weight. Therefore, in order to prevent the glass shoji 3 from tilting when the glass shoji 3 is closed, as shown in FIG. support roller 39 for rotation. A metal roller receiver 40 is fixed to a portion of the upper surface of the lower frame 5 that is positioned below the support rollers 39 when the glass shoji 3 is closed. The support rollers 39 are rotatable around a rotating shaft 41 arranged in the width direction of the glass shoji 3 (the in-plane direction when the glass shoji 3 is closed), and when the glass shoji 3 is opened and closed, the upper surface of the roller support 40 , and stops on the upper surface of the roller support 40 when the glass shoji 3 is closed.

The glass shoji 3 can be opened and closed based on the turning operation of an operation handle 42 arranged on the indoor side and on the front side of the door. When the operation handle 42 is rotated, the links of the lock mechanisms 43a and 43b (see FIG. 1) arranged inside the vertical frame 29 on the side of the door are actuated to rotate the engaging claw pieces 44, respectively. As a result, as shown in FIG. 8, the engaging claw piece 44 is protruded from the vertical frame 29 to the outside or housed inside the vertical frame 29 . In the closed state of the glass shoji 3, when the engaging claw piece 44 and the receiving tool 45 fixed to the vertical frame 6 are engaged, the glass shoji 3 cannot be opened (locked state), and the engaging claw piece 44 and the receiving piece 44 are locked. When the engagement with the fixture 45 is released, the glass shoji 3 becomes openable (unlocked state).

[Fireproof structure of window device 1]
The window device 1 of this example is designed so that the gap between the window frame 2 and the glass shoji 3 and the drain hole 20 provided in the lower frame 5 become passages for flames and hot air when a fire occurs. To prevent.

First, the structure for preventing the gap between the window frame 2 and the glass shoji 3 from becoming a path for fire, hot air, etc. will be described.
In this example, in order to close the gap between the window frame 2 and the glass shoji 3 in the event of a fire, the heating foam materials 7a to 7c are foamed at least in the thickness direction of the lower frame 5 and the vertical frame 6 by heating. are attached using a plurality of heated foam fittings 46, 46a. Specifically, two types of heating foam materials 7a and 7b that are long in the vertical direction are attached to the vertical frame 6 using a plurality of heating foam material fixtures 46 and screws 48a and 57. A heating foam material 7c elongated in the in-plane direction is attached to the frame 5 using a plurality of heating foam material fixtures 46a.

The heat foaming materials 7a to 7c (and a heat foaming material 7d to be described later) are plate-shaped (band-shaped, sheet-shaped) with a thickness of about several millimeters, and are foamed (expanded) at least in the plate thickness direction by heating, and are fireproof. For example, the trade name "Fi-Block" manufactured by Sekisui Chemical Co., Ltd. can be used. "Fi-Block" 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.). As the heat foaming material, a material that foams not only in the plate thickness direction but also in directions perpendicular to the plate thickness direction (width direction and length direction) can be used.

[Mounting structure of heating foam members 7a and 7b to vertical frame 6]
In this example, a heating foam material 7a (see FIGS. 1, 3, and 4) is attached to the outdoor side surface of the vertical frame indoor side plate portion 24 constituting the vertical frame 6 over the entire length in the vertical direction. In addition, flammability generated by dissolving resin parts (for example, spacers 30, sealing materials 33, setting blocks 35, spacer blocks 36, sealing materials 37a and 37b, bearing rollers 39) attached to the glass shoji 3 Gas tends to move downward under its own weight. Therefore, in order to improve the fireproof performance of the lower portion of the window device 1, a heating foam member 7b (see FIG. 4) is attached to the lower portion of the inner surface of the vertical frame base portion 23 that constitutes the vertical frame 6. ing.

The heating foam material 7a is applied to a portion of the outdoor side surface of the vertical frame indoor side plate portion 24 that is located outside the locking groove 10c in the in-plane direction, with the plate thickness direction aligned with the indoor and outdoor directions. installed. The heating foam material 7 a faces the gap 47 a that exists between the vertical frame substrate portion 23 and the vertical frame 29 . On the other hand, the heating foam material 7b is attached to an intermediate portion of the inner surface of the vertical frame base plate portion 23 in the indoor/outdoor direction with the plate thickness direction aligned with the in-plane direction. The heating foam material 7b also faces the gap 47a. The width dimension (dimension in the indoor/outdoor direction) of the heating foam material 7b is approximately twice the width dimension (dimension in the in-plane direction) of the heating foam material 7a. On the other hand, the total length of the heating foam material 7b is about 1/4 to 1/8 of the total length of the heating foam material 7a.

In this example, the heating foam material 7a is attached to the outdoor side surface of the vertical frame indoor side plate portion 24 with an adhesive (adhesive) using an adhesive tape, and is pressed down using the heating foam material fixture 46. there is On the other hand, the heating foam material 7b is attached to the inner surface of the vertical frame substrate portion 23 with an adhesive using an adhesive tape, and is fixed by screwing. The reason why the mounting structures are different between the heating foam material 7a and the heating foam material 7b is that the heating foam material 7a and the heating foam material 7b are attached at different positions. That is, since the indoor side surface of the vertical frame indoor side plate portion 24 (and the lower frame indoor side plate portion 15) where the heating foam material 7c is attached faces the indoor space, Adopting a fixing structure using screws, if the tip of the screw protrudes into the room, there is a possibility that it will become a problem in terms of design. This is because the side surfaces face the frame, so even if the tip of the screw protrudes outward, there is no problem in terms of design. In other words, it is difficult to employ a screw-fixing structure for the vertical frame indoor side plate portion 24, but there is no problem in employing a screw-fixing structure for the vertical frame base plate portion 23. .

[Structure of Heating Foam Mounting Tool 46]
In this example, in order to hold down the heating foam material 7a to the vertical frame indoor side plate portion 24, a plurality of heating foam material fixtures 46 are screwed and fixed to the vertical frame base plate portion 23 at predetermined intervals in the vertical direction. ing. Of the plurality of heating foaming material fittings 46, the heating foaming material fittings 46 arranged in the range from the upper part to the middle part of the vertical frame 6 are directly screwed and fixed to the vertical frame base portion 23 by screws 48. . On the other hand, the heating foam material fixture 46 arranged in the lower part of the vertical frame 6 is screwed and fixed with the heating foam material 7b sandwiched between the vertical frame base portion 23 and the heating foam material fixture 46. are doing. That is, the heating foam material 7b is screwed and fixed to the vertical frame substrate portion 23 using the screws 48a for screwing and fixing the heating foam material fixture 46 to the vertical frame substrate portion 23. As shown in FIG. For this reason, as will be described later, the heating foam material fixture 46 arranged at the bottom of the vertical frame 6 not only holds down the heating foam material 7a against the vertical frame indoor side plate portion 24, but also presses the heating foam material 7b. It is pressed against the vertical frame base plate portion 23 . However, since the heating foaming material fixture 46 is installed for the purpose of holding down the heating foaming material 7a against the vertical frame indoor side plate portion 24, the following description will be made from the top of the vertical frame 6. It centers around the heated foam fittings 46 located in the mid-extending area.

The heating foam fitting 46 is a small component made by stamping and bending a metal plate having corrosion resistance and heat resistance such as an aluminum alloy or stainless steel plate. As shown in FIG. 5, the heating foam material fixture 46 has a substantially L-shape as a whole, and includes a fixing plate portion 49, a restraining plate portion 50, and a pair of projecting arm portions 51. ing.

The fixed plate portion 49 extends in the indoor/outdoor direction that matches the plate thickness direction of the heating foam material 7a, and is arranged substantially parallel to the vertical frame substrate portion 23. As shown in FIG. The fixed plate portion 49 is longer in the length direction (indoor/outdoor direction), which is the extension direction, than in the width direction (vertical dimension), which is the direction orthogonal to the extension direction. The fixing plate portion 49 has a shape of an ellipse cut in half along the long axis direction, and the outdoor side half portion (front half portion) has a semicircular shape. In addition, the fixed plate portion 49 has a screw insertion hole 52, which is a through hole, in its outdoor portion. The screw insertion hole 52 is a circular hole having a circular opening shape. As shown in FIG. 7, the central axis O of the screw insertion hole 52 is arranged so as to overlap the restraining plate portion 50 in the indoor/outdoor direction. The fixing plate portion 49 is screwed and fixed to the inner surface of the vertical frame base portion 23 using screws 48 ( 48 a ) inserted through the screw insertion holes 52 . A threaded hole 53 for screwing the screw 48 (48a) is previously formed in the vertical frame base portion 23. As shown in FIG.

The restraining plate portion 50 extends from the widthwise central portion of the indoor end portion of the fixing plate portion 49 located on the side closer to the heating foam material 7a so as to be bent inward in the in-plane direction at a substantially right angle. It is arranged substantially parallel to the frame interior side plate portion 24 . Therefore, the holding plate portion 50 is arranged substantially perpendicular to the fixed plate portion 49 . A base half portion 54 of the pressing plate portion 50 has a substantially trapezoidal shape, and the width dimension (vertical dimension) becomes smaller toward the tip side. A front half portion 55 of the pressing plate portion 50 has a substantially rectangular shape, and the width dimension is constant over the entire length. The width dimension of the front half portion 55 is the same as the width dimension of the tip portion of the base half portion 54 . The total length L ₅₀ of the restraining plate portion 50 is shorter than the total length L ₄₉ of the fixed plate portion 49 and shorter than the width dimension H _7a of the heating foam material 7a (L ₅₀ <L ₄₉ , L ₅₀ <H _7a ). Also, the width dimension H ₅₀ at the base end portion of the pressing plate portion 50 is smaller than the width dimension H ₄₉ of the fixing plate portion 49 (H ₅₀ <H ₄₉ ). The holding plate portion 50 having such a shape holds down the outdoor side surface of the heating foam material 7a with the indoor side surface, which is a flat surface, in a state where the heating foam material fixture 46 is fixed to the vertical frame 6 . That is, the heating foam material 7a is pressed toward the indoor side (vertical frame indoor side plate part 24) in a state in which the indoor side surface of the restraining plate portion 50 is in surface contact with the outdoor side surface of the heating foam material 7a. . In this example, the holding plate portion 50 is made smaller than the fixed plate portion 49 so that the contact area of the holding plate portion 50 with the heating foam material 7a is smaller than the contact area of the fixed plate portion 49 with the vertical frame base portion 23. are doing. Further, the contact area of the restraining plate portion 50 with respect to the heating foam material 7a is the head of the screw 48 (48a) with respect to the heating foam material 7a, assuming that the heating foam material 7a is directly screwed and fixed by the screw 48 (48a). smaller than the contact area of the Further, the contact area of the front half portion 55 with the heating foam material 7a is made smaller than the contact area of the base half portion 54 with the heating foam material 7a.

The pair of protruding arm portions 51 are provided on both sides in the width direction of the indoor side end portion of the fixed plate portion 49 . The pair of protruding arm portions 51 protrude outward in the width direction from the fixed plate portion 49 and protrude toward the indoor side, which is the direction closer to the heating foam material 7a than the fixed plate portion 49 . The indoor-side end surface of each projecting arm portion 51 is a flat surface and is positioned on the same plane as the indoor-side side surface of the restraining plate portion 50 . For this reason, as shown in FIG. 6, the pair of protruding arm portions 51, in a state where the heating foam material fixture 46 is fixed to the vertical frame 6, is attached to the outdoor side of the heating foam material 7a by the respective indoor end faces. hold down the sides. Further, since the protruding arm portion 51 protrudes outward in the width direction from the fixing plate portion 49, it functions as a grip portion for a worker to grip with his or her fingers when fixing the heating foam material fixture 46 by screwing. . Furthermore, it also exhibits the function of preventing the heating foaming material fixture 46 from rotating when the heating foaming material fixture 46 is fixed by the screw 48 (48a).

In this example, a screw 48 (48a) inserted through a screw insertion hole 52 of the fixing plate portion 49 is screwed into a screw hole 53 formed in the vertical frame base portion 23, thereby vertically mounting the heating foam material fixture 46. It is screwed and fixed to the frame base portion 23, and in this state, the heating foam material 7a is pushed indoors in the plate thickness direction by the indoor side surface of the restraining plate portion 50 and the indoor side end surfaces of the pair of protruding arm portions 51. hold it down. Therefore, it is possible to effectively prevent the heated foam material 7a from peeling off from the indoor side plate portion 24 of the vertical frame before being foamed. When a fire occurs, the heating foam material 7a is foamed at least in the indoor-outdoor direction, which is the plate thickness direction, and closes the gap 47a existing between the vertical frame base portion 23 and the vertical frame 29. As shown in FIG.

Since the heating foam material fixture 46 has a substantially L shape, it can be arranged at the corner between the inner side surface of the vertical frame base plate portion 23 and the outdoor side side surface of the vertical frame indoor side plate portion 24. can. Therefore, the heating foam material fixture 46 can be installed in a small space and can effectively prevent interference with other members. Therefore, as shown in FIGS. 8 and 9, the heating foaming material fixture 46 is connected to a receiving fixture 45 fixed to the vertical frame 6 on the door tip side and a negative pressure receiving metal fixture fixed to the vertical frame 6 on the door trailing side ( It becomes possible to attach it to an adjacent position such as a restraining metal fitting 56. As a result, the heating foaming material 7a can be reliably foamed on the receiving device 45, the negative pressure receiving metal fitting 56, and their surroundings.

In this example, the pressing plate portion 50 presses the heating foam material 7a at a plurality of locations in the length direction (vertical direction). Therefore, compared with the pair of plate-like pieces 103 existing over the entire length of the heating and foaming material 100 as in the conventional structure shown in FIG. . In addition, since the contact area of the restraining plate portion 50 with respect to the heat foaming material 7a is kept small, it is possible to effectively prevent the restraining plate portion 50 from interfering with the foaming of the heat foaming material 7a.

In the heating foam material fixture 46, the fixing direction by the screw 48 (48a) and the pressing direction of the heating foam material 7a do not coincide with each other, but are perpendicular to each other. Therefore, it is possible to sufficiently prevent the fixing plate portion 49 from interfering with the foaming of the heating foam material 7a. Furthermore, since the central axis O of the screw insertion hole 52 is arranged so as to overlap the holding plate portion 50 in the indoor and outdoor directions, the head of the screw 48 (48a) inserted through the screw insertion hole 52 is heated and foamed. It can be positioned (hidden) on the rear side of the pressing plate portion 50 with respect to the foaming direction of the material 7a. Therefore, it is possible to effectively prevent the head of the screw 48 (48a) from interfering with the foaming of the heating foam material 7a. As a result, in this example, the gap 47a can be effectively closed by the heating foam material 7a.

As shown in FIGS. 10 and 11, the heating foam material 7b is screwed and fixed to the lower portion of the inner surface of the vertical frame base portion 23 using a pair of upper and lower screws 48a and 57. there is Of the pair of screws 48a and 57, the upper screw 48a is also used as a screw for screwing and fixing the heating foam material fixture 46 to the vertical frame base portion 23, as described above. Specifically, the screws 48a inserted through the screw insertion holes 52 of the heating foaming material fixture 46 and the through holes 58 of the heating foaming material 7b are respectively screwed into the screw holes 53 of the vertical frame base portion 23, whereby the heating is performed. The foaming material fixture 46 and the heating foaming material 7b are screwed and fixed to the vertical frame base plate portion 23 with screws 48a. For this reason, the upper portion of the heating foam material 7b is fixed by screws while being held down in the plate thickness direction by the fixing plate portion 49 of the heating foam material fixture 46 . On the other hand, the lower portion of the heating foam material 7b is formed by screwing the screw 57 inserted through the through hole 58 of the heating foam material 7b into the screw hole 53 of the vertical frame base portion 23 so that the head of the screw 57 is It is screwed and fixed to the vertical frame base plate portion 23 without being held down by any other member. Such a heating foam material 7b foams at least in the in-plane direction, which is the plate thickness direction, when a fire occurs, and closes the lower portion of the gap 47a existing between the vertical frame base portion 23 and the vertical frame 29. As shown in FIG. Thereby, the fire prevention performance in the lower part of the window device 1 can be improved.

[Mounting structure of heating foam material 7c to lower frame 5]
In this example, the heating foam material 7c is attached to the outdoor side surface of the lower frame indoor side plate portion 15 constituting the lower frame 5 over the entire length in the in-plane direction. For this reason, the heating foam material 7c is also arranged in a range aligned with the entire drain hole 20 with respect to the in-plane direction. Such a heating foam material 7c not only closes the gap between the window frame 2 and the glass shoji 3 in the event of a fire, but also prevents the water drain hole 20 provided in the lower frame 5 from passing flames and hot air. It also works to prevent it from happening.

The heating foam material 7c is attached to a portion of the outdoor side surface of the lower frame indoor side plate portion 15 located below the locking groove 10b with the plate thickness direction aligned with the indoor/outdoor direction. there is The heating foam material 7c faces a gap 47b (including a space 60 described later) existing between the upper and lower plate portions 17 and the lower frame 28. As shown in FIG. The width dimension (vertical dimension) of the heating foam material 7c is larger than the width dimension (in-plane dimension) of the heating foam material 7a attached to the outdoor side surface of the vertical frame indoor side plate portion 24 .

In this example, the heating foam material 7c is attached to the outdoor side surface of the lower frame indoor side plate portion 15 with an adhesive using an adhesive tape, and is held down using the heating foam material fixture 46a.

[Structure of the heating foam material fixture 46a]
In this example, in order to hold down the heating foam material 7c to the lower frame indoor side plate portion 15, a plurality of (two in the illustrated example) heating foam material fixtures 46a are mounted at predetermined intervals in the in-plane direction. It is screwed and fixed to the subordinate plate portion 17 .

Like the heating foaming material fitting 46, the heating foaming material fitting 46a is a small component made by subjecting a metal plate having corrosion resistance and heat resistance such as an aluminum alloy or a stainless steel plate to press working such as punching and bending. . As shown in FIG. 14, the heating foam material fixture 46a includes a fixing plate portion 49a and a restraining plate portion 50a.

The fixed plate portion 49 a extends in the indoor/outdoor direction that matches the plate thickness direction of the heating foam material 7 c and is arranged substantially parallel to the upper and lower plate portions 17 . The fixed plate portion 49a is configured in a substantially rectangular shape, and has a pair of screw insertion holes 52a, each of which is a through hole, in the outdoor portion. The screw insertion hole 52a is a circular hole having a circular opening shape. The fixing plate portion 49a is screwed and fixed to the upper surface of the upper and lower plate portions 17 using screws 48b inserted through the screw insertion holes 52a. In this example, the fixed plate portion 49a is indirectly screwed and fixed to the upper and lower plate portions 17 via a swing stop member 59 provided on the inner side of the stay 38 in the in-plane direction. However, the fixing plate portion 49a may be fixed directly to the upper and lower plate portions 17 by screwing.

The restraining plate portion 50a extends so as to bend obliquely upward from the widthwise (in-plane direction) central portion of the indoor-side end portion of the fixed plate portion 49a located on the side closer to the heating foam material 7c. The included angle between the pressing plate portion 50a and the fixed plate portion 49a is an obtuse angle. The holding plate portion 50a has a substantially rectangular shape as a whole, and the width dimension (in-plane direction dimension) is constant over the entire length. The width dimension H _50a of the restraining plate portion 50a is sufficiently smaller than the width dimension H _49a of the fixing plate portion 49a. In the illustrated example, the width dimension H _50a of the restraining plate portion 50a is approximately ⅛ of the width dimension H _49a of the fixing plate portion 49a. With the heating foaming material fixture 46a fixed to the lower frame 5, the restraining plate part 50a restrains the vertical middle part of the outdoor side surface of the heating foaming material 7c by the indoor end, which is the leading end of the restraining plate part 50a. wear. That is, only the tip portion of the pressing plate portion 50a contacts the heating foam material 7c, and presses the heating foam material 7c toward the indoor side (lower frame indoor side plate portion 15). In this example, the contact area of the restraining plate portion 50a with the heating foam material 7c is made smaller than the contact area of the fixed plate portion 49a with the swing stop member 59. As shown in FIG. Further, the contact area of the pressing plate portion 50a with the heating foam material 7c is larger than the contact area of the head of the screw 48b with the heating foam material 7c when it is assumed that the heating foam material 7c is directly screwed and fixed by the screw 48b. is small enough.

In this example, a screw 48b inserted through a screw insertion hole 52a of the fixing plate portion 49a is screwed into a threaded hole 53a formed in advance in the upper and lower plate portions 17, thereby attaching the heating foam material fixture 46a to the upper and lower plates. It is screwed and fixed to the portion 17, and in this state, the indoor side end portion of the pressing plate portion 50a presses the heating foam material 7c toward the indoor side in the plate thickness direction. Therefore, it is possible to effectively prevent the heating foam material 7c from peeling off from the lower frame indoor side plate portion 15 before foaming. When a fire occurs, the heating foam material 7c foams at least in the indoor-outdoor direction, which is the plate thickness direction, and closes the gap 47b existing between the upper and lower plate portions 17 and the lower frame 28. As shown in FIG.

Furthermore, in this example, the holding plate portion 50a holds down the heating foam material 7c at a plurality of locations in the longitudinal direction (in-plane direction). Furthermore, the contact area of the pressing plate portion 50a with respect to the heating foam material 7c is kept small. Therefore, it is possible to effectively prevent the pressing plate portion 50a from interfering with the foaming of the heating foam material 7c.

Further, in the heating foaming material fixture 46a, the fixing direction by the screw 48b and the pressing direction of the heating foaming material 7c do not coincide with each other, but are perpendicular to each other. Therefore, it is possible to effectively prevent the fixing plate portion 49a from interfering with the foaming of the heating foam material 7c. As a result, in this example, the gap 47b can be effectively closed by the heating foam material 7c. In addition, since the sandwiched angle between the restraining plate portion 50a and the fixed plate portion 49a is an obtuse angle and the tip portion of the restraining plate portion 50a presses down the heating foam material 7c, the fixed plate portion 49a is , can be arranged at a position distant from the pressing plate portion 50a to some extent. Further, the obliquely arranged holding plate portion 50a can prevent interference with other members.

As described above, in the window device 1 of this example, the heating foam materials 7a and 7c are not only attached to the lower frame 5 and the vertical frame 6 with an adhesive, but also the heating foam material fixtures 46 and 46a are attached. It is utilized to hold down the heating foam materials 7a and 7c in the plate thickness direction. Therefore, it is possible to prevent the heated and foamed materials 7a and 7c from coming off from the lower frame 5 and the vertical frame 6 before being foamed. In addition, instead of locking the heating foam materials 7a and 7c in the recessed grooves formed in the lower frame 5 and the vertical frame 6, the heating foam material fixture 46, which is a separate part from the lower frame 5 and the vertical frame 6, It is possible to attach the heated foam 7a, 7c to existing window devices 1 as well as to new window devices 1, because of the hold down by means of 46a.

In addition, in this example, since the heating foaming materials 7a and 7c are held down at a plurality of locations by the heating foaming material fittings 46 and 46a, the holding plate portions can be held in place like plate-like pieces when engaging with the recessed grooves. 50, 50a do not need to exist over the entire length of the heating foam materials 7a, 7c. Further, since the contact area of the restraining plate portions 50, 50a with respect to the heating foam materials 7a, 7c is kept small, the restraining plate portions 50, 50a are effectively prevented from hindering the foaming of the heating foam materials 7a, 7c. can. As a result, when a fire occurs, the gaps 47a and 47b can be filled with the heated foam materials 7a and 7c over the entire length without gaps. As a result, the gap between the window frame 2 and the glass shoji 3 can be prevented from becoming a path for fire, hot air, and the like. Furthermore, since the heating foam material fixtures 46 and 46a are fixed by the screws 48, 48a and 48b and the pressing directions of the heating foam materials 7a and 7c are not matched with each other, they are different from each other. It becomes possible to attach the heating foam members 7a and 7c to the portions such as the side plate portion 24 and the indoor side plate portion 15 of the lower frame, which were difficult to attach due to the protruding ends of the screws. It is possible to make it difficult to receive restrictions on the mounting position of the.

Next, a structure for preventing the drainage hole 20 provided in the lower frame 5 from becoming a path for fire, hot air, etc. will be described.
As described above, the lower frame 5 that constitutes the window device 1 of this example is a solid type that does not have a hollow portion, which is a space surrounded on all sides on the indoor side. There is no drainage hole as a through hole. Also, the drainage hole 20 formed in the upper and lower plate portion 17 is attached with a drainage device 21, and it is difficult to block it directly with the heated foam material. Therefore, in this example, as shown in FIG. 15, the space 60 existing below the drain hole 20 is partitioned so as to be surrounded on all four sides, and the partitioned space 60 is closed with the heating foam material 7c in the event of a fire. This prevents the drain hole 20 from becoming a path for fire, hot air, and the like. The structure of this example will be specifically described below.

For example, as shown in FIG. 15, the space 60 existing below the drain hole 20 is surrounded on three sides by the upper plate portion 16, the lower frame indoor side plate portion 15, and the upper and lower plate portions 17 as it is. , the outdoor side is open. Therefore, in order to block (partition) the outdoor side of the space 60, a fire prevention fitting 61 is attached to the lower frame 5, and a fire prevention wall 62 is vertically installed between the upper plate portion 16 and the upper and lower plate portions 17. is erected. In this example, by providing such a fire wall 62, the space 60 existing below the drain hole 20 is partitioned so as to be surrounded on all four sides (upper side, lower side, indoor side and outdoor side). The indoor-side side surface of the fire wall 62 faces the heating foam material 7c arranged over the entire length of the lower frame 5 including the portion aligned with the entire drain hole 20 in the in-plane direction.

The fire prevention fitting 61 is made by subjecting a metal plate material having corrosion resistance and heat resistance such as an aluminum alloy or a stainless steel plate to press working such as punching and bending. and Such a fire prevention fitting 61 is arranged in a portion of the lower frame 5 that is aligned with the drain hole 20 in the in-plane direction.

The mounting plate portion 63 has a substantially U-shape in plan view, and is fixed to the upper and lower plate portions 17 by screwing. The mounting plate portion 63 has a rectangular cutout 65 that is open to the outside, and inside the cutout 65 is a roller support 40 for preventing the tip side of the glass shoji 3 from tilting. are placed. A pair of screw insertion holes 66 are formed at the indoor-side end portion of the mounting plate portion 63 on both sides of the notch 65 in the in-plane direction. The mounting plate portion 63 is screwed and fixed to the upper surface of the upper and lower plate portions 17 by screws 67 inserted through the screw insertion holes 66 . Note that the widthwise central portion of the mounting plate portion 63 and the lengthwise central portion of the water drain hole 20 are located at the same position with respect to the in-plane direction.

The fire wall 62 has a rectangular shape and extends vertically upward from the indoor end of the mounting plate portion 63 so as to be bent at a substantially right angle. The fire wall 62 is located outside the drain hole 20 and is provided in a range aligned with the entire drain hole 20 with respect to the in-plane direction. The length dimension (in-plane dimension) L ₆₂ of the fire wall 62 is larger than the width dimension (in-plane dimension) H ₆₃ of the mounting plate portion 63 and the length dimension L ₂₀ of the drain hole 20 ( _L62 > _H63 , _L62 > _L20 ). In the illustrated example, the length dimension L ₆₂ of the firewall 62 is twice the width dimension H ₆₃ of the mounting plate portion 63 (L ₆₂ =2H ₆₃ ), and approximately the length dimension L ₂₀ of the drain hole 20. 2.7 times (L ₆₂ ≈2.7L ₂₀ ). For this reason, both widthwise side portions of the fire wall 62 are positioned away from the drain hole 20 in the in-plane direction. The width dimension (vertical dimension) _H62 of the fire wall 62 is slightly smaller than the width dimension (vertical dimension) _H7d of the heating foam material 7d, which will be described later. Also, the fire wall 62 is arranged substantially parallel to the lower frame indoor side plate portion 15 . The indoor side surface of the firewall 62 faces the heating foam material 7c, and the outdoor side surface of the fire wall 62 faces the support roller 39 with the heating foam material 7d, which will be described later, interposed therebetween.

The restraining portion 64 has a substantially L-shape, protrudes upward from the center portion in the longitudinal direction of the upper end portion of the fire wall 62, and extends toward the indoor side so as to be bent at a substantially right angle. ing. The width dimension (in-plane direction dimension) of the restraining portion 64 is constant over the entire length. The width dimension H ₆₄ of the restraining portion 64 is sufficiently smaller than the length dimension L ₆₂ of the firewall 62 . In the illustrated example, the width dimension H ₆₄ of the restraining portion 64 is approximately 1/27 of the length dimension L ₆₂ of the firewall 62 . With the fire prevention fitting 61 fixed to the lower frame 5, the restraining portion 64 restrains the upper part of the outdoor side surface of the heating foam material 7c by the indoor side end portion, which is the tip portion. That is, the heated foam material 7c is pressed toward the indoor side (lower frame indoor side plate portion 15). In this way, the fire prevention fitting 61 of this example not only includes the fire prevention wall 62 for partitioning the space 60 below the drain hole 20, but also holds down the heating foam material 7c against the lower frame indoor side plate portion 15. Equipped with a hold-down portion 64, it performs the same function as the heating foam fittings 46a spaced apart in the in-plane direction.

Furthermore, in this example, the heating foam material 7d is attached to the outdoor side surface of the fire wall 62 over the entire length. The heating foam material 7d is attached to the outdoor side of the fire wall 62 with an adhesive tape and fixed with a pair of screws 68 with the plate thickness direction aligned with the indoor/outdoor direction. ing. Specifically, screws 68 inserted through through holes 69 formed on both sides in the longitudinal direction of the heating foam material 7d are screwed into threaded holes 70 formed on both sides in the longitudinal direction of the firewall 62 . , the heating foam material 7d is fixed to the firewall 62 by screwing. The heating foam material 7d attached to the fire wall 62 and the heating foam material 7c attached to the lower frame indoor side plate portion 15 are arranged so as to overlap each other in parallel in the indoor-outdoor direction. Since the width dimension _H7d of the heating foam material 7d is slightly larger than the width dimension _H62 of the fire wall 62, both upper and lower sides of the heating foam material 7d protrude from the fire wall 62 on both upper and lower sides.

In the window device 1 of this example as described above, the space 60 existing below the drain hole 20 is partitioned by erecting the fire wall 62 so as to be surrounded on all four sides, and the partitioned space 60 is divided into , when a fire occurs, it can be closed (filled) with the heating foam material 7c attached to the outdoor side surface of the lower frame indoor side plate portion 15. As shown in FIG. Therefore, it is possible to prevent the drain hole 20 from becoming a path for fire, hot air, and the like. Further, in this example, in order to prevent the door tip side of the glass shoji 3 from tilting downward, a support roller 39 made of synthetic resin is supported on the end portion of the lower surface of the lower frame 28 on the door tip side. , and in the event of a fire, the bearing rollers 39 can melt and generate combustible gases. However, since the fire wall 62 is erected on the indoor side of the bearing rollers 39, it is possible to effectively prevent the combustible gas from moving toward the space 60 and the drain hole 20 side. Moreover, since the heating foam material 7d is attached to the outdoor side of the fire wall 62, the heating foam material 7d foams toward the outdoor side, and the combustible gas generated by the dissolution of the support rollers 39 can be removed from the outside. You can also push it back out. Further, when the flame exists indoors, the heating foaming material 7c foams first, and when the flame exists outdoors, the heating foaming material 7d foams first. It can protect from inside and outside. Therefore, according to this example, it is possible to effectively prevent the drainage hole 20 provided in the lower frame 5 from becoming a path for flames, hot air, and the like. Therefore, it is possible to secure sufficient fireproof performance for the solid type lower frame 5 that does not have a hollow portion on the indoor side.

In the above-described embodiment, the structure for attaching the heating foaming material fixture to the lower frame and the vertical frame, which are the parts to be attached, was described, but the heating foaming material fixture of the present invention is not limited to these, It can be attached to the frame, or it can be attached to each stile constituting the stile frame body. In addition, the present invention is applicable not only to vertical sliding windows, but also to project windows such as side sliding windows, outward-opening windows, inward-opening windows, and fixed windows, as well as sliding door-type window devices and door devices. can also Further, when carrying out the present invention, the screw insertion hole provided in the heating foaming material fitting is not limited to a circular hole, and may be an elongated hole elongated in the plate thickness direction of the heating foaming material. In this case, it is possible to finely adjust the attachment position of the heating foaming material fixture, and finely adjust the pressing force of the heating foaming material.
