(Glass removal prevention)
The glass stopper 5 used for the fitting according to the present embodiment will be described using the glass stopper 5 attached to the right vertical frame 14.
As shown in FIG. 3A, the glass detachment stopper 5 is composed of a base metal 51 and a receiving metal 52. As shown in FIG. 3B, the base metal 51 is attached to the right vertical frame 14. The right vertical frame main body 141a that forms the groove bottom of the front panel of the panel is fixed by a fixing means b such as a screw, and the receiving metal fitting 52 is attached to the base metal fitting 51 from the indoor side. As shown in FIG. 2, a glass slip-off stopper 5 is formed to prevent the multilayer glass 2 from falling off to the indoor side.

As shown in FIGS. 4A to 4C, the base metal fitting 51 of the glass stopper 5 is a right vertical frame main body that is a part that forms the groove bottom of the glass front of the metal right vertical frame (frame main body) 141. A fixing surface 51a fixed to the portion 141a by a fixing means b such as a screw, and a dimension that is shorter in the longitudinal direction than the fixing surface 51a, and is located in the center in the longitudinal direction of the fixing surface 51a from the outdoor end of the fixing surface 51a. An outdoor finding surface 51b formed by bending to the peripheral side, and an inner peripheral wall 51c having a dimension longer in the longitudinal direction than the fixed surface 51a and bent from the inner peripheral end of the outdoor finding surface 51b to the indoor side. And the longitudinal direction edge part of the fixed surface 51a is formed as a short member which has a pair of standing surface 51d and 51d formed standing up in the inner peripheral side.
The inner peripheral wall 51c has a guide portion 51e formed by notching the longitudinal center portion of the base fitting 51, and a receiving fitting 52 on both sides of the guide portion 51e and facing the standing surfaces 51d and 51d. Engagement holes 51g, 51g for engaging the are formed.
A screw hole 51f for fixing with screws is formed in the fixing surface 51a, and a screw hole (not shown) for attaching the base metal fitting 51 to the right vertical frame main body 141a is also formed. The base metal fitting 51 is disposed on the inner periphery of the right vertical frame main body 141a, and the indoor side ends of the standing surfaces 51d and 51d are brought into contact with the outdoor claw portion 141f provided on the right vertical frame main body 141a. By fixing in this way, stable mounting can be achieved without rattling by fixing with one screw.
Moreover, the area | region which arrange | positions a heating foaming material can be formed in the indoor side of the glass detachment prevention 5 by attaching the glass detachment prevention 5 to the indoor side so as to contact the outdoor-side claw portion 141f. The material can also be provided through the entire length of the frame material in the longitudinal direction.

On the other hand, as shown in FIGS. 4D to 4F, the receiving metal fitting 52 of the glass stopper 5 is a prospective surface 52a engaged with the base metal fitting 51, and the longitudinal length of the indoor end of the prospective surface 52a. A glass receiving surface 52b formed by bending the central portion in the direction toward the inner peripheral side is formed as a short member having a substantially L-shaped cross section.
A center portion in the longitudinal direction of the prospective surface 52a is formed with a guided portion 52d that is cut and raised to the inner peripheral side with the glass receiving surface 52b as a base point, and anti-glass receiving surfaces on both sides in the longitudinal direction of the guided portion 52d. Fitting portions 52e and 52e having cut-and-raised pieces 52c and 52c formed by cutting to the inner peripheral side from the 52b side are formed.

When the multi-layer glass 2 is held by the glass detachment stopper 5, as shown in FIG. 5A, the fixing surface 51a is fixed to the right vertical frame main body 141a of the right vertical frame 14 by screws b or the like. The prospective surface 52a of the receiving metal fitting 52 is inserted from the indoor side between the inner peripheral ends of the raised surfaces 51d, 51d of the base metal fitting 51 and the inner peripheral wall 51c.
At that time, the guided portion 52 d of the receiving metal fitting 52 is guided along the guide portion 51 e of the base metal fitting 51, thereby restricting insertion of the receiving metal fitting 52 in an inclined state.

As the receiving metal fitting 52 is inserted, the cut and raised pieces 52c, 52c of the fitting portions 52e, 52e of the receiving metal 52 come into contact with the outer peripheral surface of the inner peripheral wall 51c and are elastically deformed, and then the engagement of the inner peripheral wall 51c. It restores with the joint holes 51g and 51g, and engages with the engagement holes 51g and 51g.
As a result, as shown in FIG. 5B, the fitting portions 52e and 52e of the receiving metal fitting 52 are fitted in the state where they are inserted between the rising surfaces 51d and 51d of the base metal fitting 51 and the inner peripheral wall 51c. While being fixed, the glass receiving surface 52b of the metal fitting 52 is in contact with or close to the indoor side surface of the multilayer glass 2, whereby the glass can be held.

Thus, when the receiving metal 52 is fixed to the base metal 51, the guided portion 52d of the receiving metal 52 is guided along the guide 51e of the base metal 51, so that the receiving metal 52 is inclined. Therefore, the cut and raised pieces 52c and 52c of the receiving metal fitting 52 can be reliably locked in the engaging holes 51g and 51g of the base metal fitting 51.
The glass detachment stopper 5 is disposed in the upper frame portion and the left and right vertical frame portions of the frame body 1, and the multilayer glass 2 is fixed to the right vertical frame main body 141 a on the indoor side in the upper side and the left and right vertical sides. Even if the resin frame portion arranged on the indoor side of the joinery melts due to a fire in contact with or close to the glass detachment stopper 5, it is possible to prevent the double-glazed glass 2 from falling off the indoor side and falling. .
At this time, the receiving metal fitting 52 of the glass stopper 5 is arranged on the inner peripheral side of the inner peripheral end of the standing surfaces 51 d and 51 d of the base metallic fitting 51, so that it is arranged at a position close to the end face of the multilayer glass 2. Therefore, it is not necessary to increase the size of the glass receiving surface 52b in contact with or close to the indoor side surface of the double glazing 2 more than necessary, and deformation of the glass receiving surface 52b at the time of fire can be reduced. Thus, the detachment of the multilayer glass 2 can be reliably suppressed.

Since the glass stopper 5 is formed in a short shape, the inner peripheral side of the fitting portions 52e, 52e of the receiving metal fitting 52 fitted to the base metal 51 and the outer peripheral side of the inner peripheral wall 51c of the base metal 51 Between them, for example, by inserting a tool such as a flat-blade screwdriver from the indoor side toward the outdoor side, Can be released, and the receiving metal fitting 52 can be removed to the indoor side.
Therefore, when the indoor and outdoor glass panels 21 and 22 constituting the double-glazed glass 2 are damaged, the receiving metal fitting 52 can be easily removed and replaced, and the maintainability is excellent.

  In the joinery of this embodiment, the short glass stopper 5 is installed in two places when the height dimension is 1100 mm or more when provided in the vertical frame, and near the center in the height direction when the height dimension is less than 1100 mm. However, the number and location of the glass stoppers 5 are not particularly limited.

(Fireproof structure)
In the frame body 1 of the FIX joinery according to the present embodiment, a panel opening is formed by the metal lower frame 121 and the resin lower frame 122 for the lower frame portion, and the upper frame portion is made of an extruded material of aluminum alloy or the like. The left and right vertical frame portions are formed by the metal upper frame 111 and the resin upper pressing edge 113, so that the panel left side is formed by the metal left vertical frame 131, the metal right vertical frame 141, the resin left vertical pressing edge 133, and the resin right vertical pressing edge 143. The upper frame and the left and right vertical frames are configured as inner pressing edges.
And in each glass frontage, the heating foam material is arrange | positioned over the substantially whole periphery of the multilayer glass 2, and it is foamed from a perimeter to the small edge of the multilayer glass 2 at the time of a fire. It is configured.

Specifically, as shown in FIG. 1, for the upper frame portion, a heating foam material 61 is disposed on the indoor side surface of the outdoor side wall 111 b of the metal upper frame 111 over substantially the entire length direction, and heating foaming is performed. The material 61 is arranged toward the top edge of the multilayer glass 2. For this reason, when a fire occurs, the heated foam material 61 expands toward the upper end edge of the multilayer glass 2.
In addition, the heating foam material 66 is disposed on the outdoor side surface of the glass receiving surface 52b of the glass stopper 5 disposed in the panel opening of the upper frame portion. When a fire occurs, the heating foam material 66 is It expands toward the top edge of the double glazing 2.

  As for the lower frame portion, similarly to the upper frame portion, the heating foam material 62 is disposed on the indoor side surface of the outdoor side wall 121b of the metal lower frame 121 over substantially the entire length direction, and the heating foam material 62 is a multilayer. It is arranged toward the lower end edge of the glass 2. For this reason, when a fire occurs, the heated foam material 62 expands toward the lower end edge of the multilayer glass 2.

In addition, as shown in FIG. 2, the left vertical frame portion is heated and foamed over the substantially entire length in the longitudinal direction on the indoor side surface of the outdoor side wall 131b of the metal left vertical frame 131, as in the upper frame portion and the lower frame portion. A material 63 is arranged. Furthermore, a heating foam 64 is disposed over the entire length of the vertical frame in the outdoor portion of the glass stopper 5 at the bottom of the groove at the panel opening of the left vertical frame 13. About the position where the glass stopper 5 is arrange | positioned in the prospective direction, the heating foam material 65 is intermittently arrange | positioned in the site | part where the glass stopper 5 is not arrange | positioned.
Furthermore, the heating foam material 66 is arrange | positioned at the outdoor side surface of the glass receiving surface 52b of the glass stopper 5 arrange | positioned in the panel front opening of the left vertical frame part.
When a fire occurs, the heated foam materials 63, 64, 65, 66 expand toward the left and right end edge of the multilayer glass 2.
Thus, each heating foam material 61 thru | or heating foam material 66 is arrange | positioned over the perimeter of the multilayer glass 2 by foaming toward the edge of the multilayer glass 2 at the time of a fire outbreak. By suppressing the heating of the sealing material, the generation of combustible gas from the sealing material is prevented, and the communication between the inside and outside of the room is prevented.
In addition, the fire prevention structure of the left and right vertical frames 13 and 14 is not basically different between the left and right, and the description of the fire prevention structure of the right vertical frame 14 is omitted.

And when the heating foam material 61 thru | or the heating foam material 65 arrange | positioned in the metal frame 111, 121, 131, 141 expand | swell, the base metal fitting 51 of the glass detachment prevention 5 exists in the foaming space. Since 51 is short-shaped, it can foam to the edge of the multilayer glass 2 in the area | region where the base metal fitting 51 does not exist, and can cover the edge of the multilayer glass 2 first.
And in the area | region where the base metal fitting 51 of the glass detachment prevention 5 exists, the base metal fitting 51 has the outdoor finding surface 51b facing the outdoor side area | region of the glass detachment prevention 5 in which the heating foam material 61 thru | or the heating foam material 64 foam. Since only the center has a dimension shorter than the longitudinal dimension of the fixed surface 51a and the gaps 51h and 51h are formed on both sides in the longitudinal direction of the outdoor fitting surface 51b of the base metal 51, the foaming is heated. As shown by the arrow Y in FIGS. 4 (b) and 5 (b), the material 61 or the heated foam material 64 enters through the gaps 51 h and 51 h toward the inside of the base metal fitting 51 of the glass stopper 5. be able to. Therefore, the heating foam materials 61 to 64 can be filled in the glass front space substantially continuously without being divided in the region where the glass stopper 5 exists, and the base metal fitting 51 of the glass stopper 5 and A fitting part with the receiving metal fitting 52 can also be covered.
Accordingly, the entire small edge of the multilayer glass 2 held by the glass stopper 5 can be integrally covered with the metal frames 111, 121, 131, 141 by the expanded heating foam 61 or heating foam 65. Since it can do, it can suppress that double glazing 2 falls off, and can prevent penetration of a flame indoors and outdoors effectively.

  As described above, the glass stopper 5 of the joinery of the present embodiment is the longitudinal direction of the glass stopper 5 with the outdoor finding surface rising on the outdoor side (one side) of the fixed surface fixed to the metal frame material (frame material body). Since the gap is formed on both sides in the longitudinal direction of the outdoor finding surface, the heating foam material disposed on one side of the glass detachment stopper 5 of the metal frame material (frame material body) is foamed. When it does, it can penetrate the inside of the glass detachment stopper 5 through the gap, and the heating foam disposed over the entire length in the longitudinal direction of the frame body is not divided at the installation part of the glass detachment stopper, A good fire prevention structure can be constructed.

In addition, although this embodiment is demonstrated using the FIX joinery, the joinery of this invention is not limited to a FIX joinery, The structure of a glass detachment prevention and a heating foam material is a glass panel with respect to the shoji of a shoji. It can also be used as a detachment prevention and fire prevention structure.
Further, the pressing edge member is not limited to the one arranged on the indoor side of the frame body, and the pressing edge may be arranged on the outdoor side, and the material of the frame body and the pressing edge is not particularly limited. Any material can be used as long as it can be used as a frame material or a pressing edge.

And in the glass detachment prevention of the present embodiment, the gap for the heating foam to penetrate is formed in the end portion for the longitudinal direction of the glass detachment prevention, but the position is not particularly limited, It suffices if the foamed heated foam material can penetrate from the outdoor side (one side) of the glass stopper to the inside (other side) of the glass stopper.
Furthermore, in this embodiment, the glass stopper is not arranged in the lower frame part, but the glass stopper may be arranged in the same way as the upper frame part and the vertical frame part in the lower frame part. Although the glass front can be formed using the resin lower frame as the pressing member, the panel front may be formed by providing a pressing edge like the upper frame portion and the vertical frame portion.
