A mounting wall 16 extends from the side surface toward the indoor side, and the mounting wall 16 is screwed to the eaves frame 7c.

  In-groove reinforcing material 2 and out-groove reinforcing material 3 are attached to the inside and the outside of the groove 14, respectively. The in-groove reinforcing material 2 is formed by bending a steel plate to have an L-shaped cross section, and has a finding piece 21 and an expecting piece 22 and is disposed inside the groove 14. The finding piece 21 is in contact with the outdoor side wall 11 from the indoor side, and the expecting piece 22 is in contact with the expecting wall 13 from the left side (inner peripheral side). On the other hand, the reinforcing material 3 outside the groove is also formed by bending a steel plate to have an L-shaped cross section, and has a finding piece 31 and a prospecting piece 32, and is arranged outside the groove 14. The finding piece 31 is in contact with the indoor side wall 12 from the indoor side, and the expecting piece 32 is in contact with the expecting wall 13 from the right side (outer peripheral side).

  Further, the rail member 6 is provided between the indoor side wall 12 and the finding piece 21 of the in-groove reinforcing member 2 in the groove 14. The rail member 6 is made of an aluminum extruded shape, and has a substantially U-shaped cross section including an outdoor side plate 61, an indoor side plate 62, and a prospect plate 63. However, the indoor side plate 62 is formed longer than the outdoor side plate 61. The outdoor side plate 61 is in contact with the finding piece 21 of the in-groove reinforcing member 2 from the indoor side, the indoor side plate 62 is in contact with the indoor side wall 12 from the outdoor side, and the prospecting plate 63 is the in-groove reinforcing material. 2 from the left side (inner peripheral side). The outdoor side plate 61 and the indoor side plate 62 are formed with engaging pieces 64 that protrude in the expected direction at opposing positions.

  When each member is arranged in this way, from the left side (inner peripheral side), the prospective plate 63 of the rail member 6, the prospective piece 22 of the in-groove reinforcement 2, the expectation wall 13 of the guide frame 1, and the expectation of the outer reinforcement 3 Since the pieces 32 overlap, the four members are combined and screwed from the left side (inner peripheral side). Moreover, since the finding piece 31 of the outer groove reinforcing material 3, the indoor side wall 12 of the guide frame 1, and the indoor side plate 62 of the rail member 6 overlap from the indoor side, the three members are combined and screwed from the indoor side.

  The end of the shutter slat 4 is engaged with the rail member 6. The shutter slat 4 is provided with resin wind-resistant hooks 41 at both left and right ends. The wind-resistant hook 41 has an iron core inside, and has a substantially T-shaped tip as viewed from above. By inserting this tip portion into the rail member 6 from above and below, the wind-resistant hook 41 engages with the engagement piece 64 of the rail member 6 so that it can move up and down.

  Further, a refractory material 5 is provided in the groove 14 of the guide frame 1. The refractory material 5 is attached to the indoor side of the left end (inner peripheral side end) of the finding piece 21 of the reinforcing member 2 in the groove and the outdoor side of the left end (inner peripheral side end) of the indoor side plate 62 of the rail member 6. The shutter slat 4 faces the outdoor side and the indoor side, respectively. The refractory material 5 is made of an epoxy-based material, foams by heat during a fire, expands in the thickness direction (perpendicular to the mounting surface), and contacts the shutter slat 4. Further, the mohair is in contact with the shutter slat 4 on the indoor side of the left end (inner peripheral side end) of the outdoor side wall 11 of the guide frame 1 and on the outdoor side of the left end (inner peripheral side end) of the indoor side wall 12. 17 is attached.

  In the opening construction material configured in this way, the expected wall of the guide frame is sandwiched between the expected piece of the reinforcing material in the groove made of a steel plate and the expected piece of the reinforcing material outside the groove made of the same steel plate, and is directly exposed to flame heat in the event of a fire. Protects against exposure. Moreover, the reinforcing material outside the groove covers the indoor side wall and the prospective wall of the guide frame from the indoor side, and protects the groove of the guide frame from the flame heat from the indoor side. Further, the substantially U-shape is formed by combining the reinforcing material in the groove and the reinforcing material outside the groove, and the rail member is arranged on the inner side thereof. Protected from. Furthermore, even when the rail member or guide frame made of extruded aluminum is melted, the end portion of the shutter slat is supported by being fitted inside the substantially U-shaped reinforcing material in the groove and the reinforcing material outside the groove. Since the state is maintained, the shutter slat does not fall off. In addition, the fire-resistant material foams and contacts the outdoor side surface and the indoor side surface of the shutter slat during a fire. Thereby, the shutter slat is pressed by the fireproof material from both the outdoor side and the indoor side, and the shutter slat is fixed. And since a refractory material fills the clearance gap between a shutter slat and the groove | channel of a guide frame, the outdoor side and the indoor side are interrupted | blocked and it prevents that a flame wraps around. Further, the end of the shutter slat is prevented from melting, and the shutter slat is prevented from falling off. In order to protect the ends of the rail member and the shutter slat from flame heat, a method of inserting a U-shaped reinforcing material in the groove and arranging the rail member and the shutter slat inside thereof is also conceivable. However, in that case, the inside of the groove becomes cramped, and it becomes impossible to secure a clearance necessary for smoothly operating the shutter slat. For this reason, the expected width of the groove must be increased, and the appearance of the guide frame may be changed. In contrast, according to the present invention, since the reinforcing material is arranged separately in the groove and outside the groove, there is room in the groove, and without changing the expected width of the groove and the appearance of the guide frame, the groove and its The inner rail member and the end of the shutter slat can be protected from flame heat.

  Then, 2nd embodiment of the opening part building material of this invention is described.

In addition, about the groove outside reinforcement material 3, it is the same as that of 1st embodiment, and about the rail member 6, it is the same shape as 1st embodiment, Comprising: The outdoor side finding piece 21a of the reinforcement material 2a in a groove | channel and a house It is provided between the inner finding pieces 23a. When each member is arranged in this way, from the indoor side, the finding piece 31 of the outside-groove reinforcing material 3, the indoor side wall 12 of the guide frame 1, the indoor-side finding piece 23a of the in-groove reinforcing material 2a, and the indoor of the rail member 6 are arranged. Since the side plates 62 overlap, the four members are joined together and screwed from the indoor side. In the opening construction material of the second embodiment configured as described above, as in the first embodiment, the in-groove reinforcing material, the out-groove reinforcing material, and the refractory material protect the guide frame and the shutter slat from flame heat, and the shutter. Slats can be prevented from falling off.

  The present invention is not limited to the above embodiment. For example, the guide frame only needs to have an outdoor side wall, an indoor side wall, and a prospective wall, and the shape of other portions can be freely designed in consideration of the appearance, the method of attaching to the eaves frame, and the like. In addition, the rail member does not necessarily have to be attached. If there is no rail member, an engagement piece may be formed on the guide frame or the in-groove reinforcing material. However, since it takes time to form the engagement piece on the in-groove reinforcing member made of a steel plate, it is possible to manufacture more efficiently by providing the rail member. Furthermore, the overall shape of the shutter is also an example, and the shape of the upper frame, the lower frame, the saddle frame and the case, the structure of the winding device, and the like may be any. The opening building material of the present invention includes both a single shutter that can be retrofitted to the outside of a window or the like and a sash with a shutter in which the window frame and the shutter are integrated in advance.
