  The heat insulating material 15C connecting the outer frame element 15A and the inner frame element 15B is made of a resin having a lower thermal conductivity than that of the aluminum alloy. The individual heat insulating material 15C is interposed at a portion extending over the entire length between the two frame elements 15A and 15B so as to maintain a non-contact state with each other. As the heat insulating material 15C, a preformed material may be applied, or a liquid material having plasticity may be injected into each of the heat insulating material housing portions 15Ab and 15Bb.

  In order to dispose the glass panel 30 in the sub-opening 10Ab of the frame body 10 having the vertical frame 15 configured as described above, first, the support fin portion 15Ac of the outer frame element 15A is provided via the window tight material AT1. One surface of the glass panel 30 is brought into contact with the glass panel 30. From this state, by attaching the pressing edge 16 to the pressing edge mounting portion 15Bd of the inner frame element 15B, the peripheral edge portion of the glass panel 30 is sandwiched by the face material accommodation groove portion 15E formed between the support fin portion 15Ac and the pressing edge 16. You can do it. The pressing edge 16 is an extruded shape member formed of a metal material such as an aluminum alloy, like the frame elements 15A and 15B. In the present embodiment, it has a pressing base 16a having a flat plate shape, a pressing fin 16b extending from the pressing base 16a, an engagement piece 16c, and an extension cover (extension) 16d. A pressing edge 16 having the same longitudinal dimension is applied.

  The ledge base portion 16a is in contact with the ledge support surface 15Bd2a of the ledge support piece 15Bd2 via one surface 16a1. The ledge base portion 16a has a prospective dimension capable of covering the ledge engaging piece 15Bd1 and the ledge support piece 15Bd2 when abutting against the ledge support surface 15Bd2a.

  The ledge fin portion 16b is a flat plate portion bent at a right angle from one side edge portion of the ledge base portion 16a to the other surface 16a2. A ledge tight material AT3 is bonded to the bent end of the ledge fin portion 16b. The ledge tight material AT3 is an elastic member interposed between the ledge fin portion 16b and the glass panel 30, and is formed so as to be in close contact with the surface of the glass panel 30.

  The engagement piece portion 16c is a flat plate-like portion protruding from one surface 16a1 of the ledge base portion 16a. As is apparent from the drawing, the engaging piece 16c is inclined and extended so as to gradually approach the other side edge of the pressing base 16a as it protrudes from the pressing base 16a. At the extending end of the engagement piece 16c, an engagement portion 16e is provided that is bent in a hook shape in a direction close to the other side edge of the pressing base 16a. The contact surface 16a1 ′ has the same width as the expected dimension of the pressing edge support surface 15Bd2a provided on the pressing edge support piece 15Bd2 between one side edge of the pressing edge base portion 16a and the protruding position of the engagement piece portion 16c. Secured.

  The extension cover portion 16d is a flat plate-like portion provided on the other side edge portion of the pressing edge base portion 16a via the step portion 16f. The step portion 16f has a flat plate shape bent at an obtuse angle from the other side edge portion of the pressing base portion 16a to the one surface 16a1 side. The bending dimension of the step portion 16f is approximately ½ of the engagement piece portion 16c protruding from the pressing base portion 16a. The extension cover portion 16d extends from the bent end portion of the step portion 16f in a direction away from the engagement piece portion 16c so as to be parallel to the pressing edge base portion 16a. The extending width of the extended cover portion 16d from the step portion 16f is larger than the expected size of the heat insulating material 15C provided between the outer frame element 15A and the inner frame element 15B, and is supported from the pressing edge mounting portion 15Bd. The dimension is set to be smaller than the distance to the portion 15Ac. A thermally expandable member 40 is affixed to a portion that becomes one surface 16d1 in the extended cover portion 16d. The thermally expandable member 40 is a nonflammable or flame retardant member that expands when heated, and is, for example, a foam material containing thermally expandable graphite. In the present embodiment, the thermally expandable member 40 formed into a sheet shape is disposed over the entire length along the longitudinal direction of the extension cover portion 16d.

  In the pressing edge 16 having the above-described configuration, first, the engaging piece portion 16c is inserted between the pressing edge engaging piece 15Bd1 and the pressing edge support piece 15Bd2 of the inner frame element 15B. After that, if the contact surface 16a1 'of the pressing base 16a is brought into contact with the pressing support surface 15Bd2a, the engaging portion 16e of the engaging piece portion 16c is brought into contact with the engaging receiving portion 15Bd1a of the pressing edge engaging piece 15Bd1. It will be in the engaged state. At this time, the ledge fin portion 16b of the ledge 16 is arranged in a state of facing the support fin portion 15Ac of the outer frame element 15A, forms a face material accommodation groove portion 15E with the support fin portion 15Ac, and has a ledge tightness. The material AT3 comes into contact with the surface of the glass panel 30 in close contact. For this reason, the contact surface 16a1 'of the ledge base portion 16a is maintained in contact with the ledge support surface 15Bd2a by the repulsive force of the ledge tight material AT3, and the glass panel 30 and the support fin portion 15Ac of the outer frame element 15A and the ledge It will be in the state of being pinched between the 16 ledge fin portions 16b.

  Here, in the joinery in which the glass panel 30 is disposed in the sub-opening 10Ab of the frame body 10 as described above, the extension cover portion 16d of the pressing edge 16 is thermally insulated between the outer frame element 15A and the inner frame element 15B. The portion where the material 15C is provided is covered, and the thermally expandable member 40 is disposed so as to face the portion facing the heat insulating material 15C. Moreover, the elements 16a, 16b, 16c, 16d, 16e, and 16f of the pressing edge 16 are not in contact with the outer frame element 15A. Accordingly, when the joinery is used in a normal state, heat transfer between the outer frame element 15A and the inner frame element 15B is suppressed, and for example, dew condensation is generated on the inner frame element 15B and the lid member 15D. There are advantages such as not occurring.

  On the other hand, even when a fire occurs outdoors, since the heat insulating material 15C is covered with the extended cover portion 16d of the pressing edge 16 in the face material accommodating groove portion 15E, the window tight material AT1 is melted, and a flame is generated from the gap. Even if it enters, this flame does not reach the heat insulating material 15C directly. Further, when the extension cover portion 16d is heated, the thermally expandable member 40 provided on the extended cover portion 16d expands, and the expanded surface material accommodating groove portion 15E is filled with the expanded thermally expandable member 40. Therefore, even when a fire breaks out, it is possible to prevent the heat insulating material 15C from being melted, and there is no possibility that the flame between the two frame elements 15A and 15B becomes a through-hole, thereby preventing the spread of fire.

  In addition, according to this joinery, the thermally expandable member 40 is held because the thermally expandable member 40 that expands in the face material accommodation groove 15E when heated is provided in the extension cover portion 16d of the pressing edge 16. At this time, the support fin portion 15Ac does not get in the way, the operation can be easily performed, and the holding state of the thermally expandable member 40 can be easily confirmed. Therefore, there is no possibility that the heat-expandable member 40 will accidentally drop off, and it is possible to further prevent a situation where a through-hole is formed so as to pass between the two frame elements 15A and 15B from the face material receiving groove 15E. It becomes possible.

  In the above-described embodiment, only the vertical frame 15 of the frame 10 has been described. However, the same configuration may be applied to the upper frame 11 and the left and right vertical frames 13 and 14. Moreover, if it is a fitting provided with an invisible frame, it is also possible to apply to an invisible frame. Furthermore, the face material sandwiched between the support fin portion 15Ac and the pressing edge 16 is not necessarily the glass panel 30, and can be applied to a material sandwiching other face material.

  In the above-described embodiment, since the frame member is configured such that the inner frame element 15B having the pressing edge mounting portion 15Bd is on the indoor side, there is no possibility that the pressing edge 16 is removed from the outdoor side. In the present invention, the frame member may be configured such that the inner frame element is on the outdoor side.

  Furthermore, in the above-described embodiment, since the pressing edge 16 is configured such that the engagement piece portion 16c protrudes independently from the pressing edge base portion 16a extending along the extended cover portion 16d, the thermally expandable member 40 is configured. Although the pressing edge 16 can be prevented from dropping off from the pressing edge mounting portion 15Bd when the bulge expands, the configuration of the pressing edge is not limited to that of the embodiment.
