Description

The present invention relates to fittings including a resin frame and a metal core.

Conventionally, there is known a resin fitting in which a frame or the like is made of resin and a metal core material is arranged inside to improve fire resistance. The end faces of the vertical frame and the horizontal frame of the frame body are formed so as to be inclined with respect to the longitudinal direction, and the corner portions of the frame body are formed by abutting the inclined end portions. In such fittings, it has been proposed that the ends of the vertical core material of the vertical frame and the horizontal core material of the horizontal frame are similarly inclined and butted inside the frame body, and are connected by metal corner metal fittings. (See, for example, Patent Document 1).

However, for example, in the case of fittings in which the frame is separated by mullion, even if the internal metal vertical core material and horizontal core material are connected, the vertical core is exposed to high heat due to a fire or the like. There was a concern that the resin mullion located between the material and the horizontal core material would melt, causing flames and high-temperature air to penetrate indoors and outdoors.

Further, since the core material is made of metal, it is not easy to process the shape of the end portion so that the end faces of the vertical core material and the horizontal core material are inclined and abutted. However, if the ends of the vertical core material and the horizontal core material are not processed so as to abut each other and are simply extended, a rectangular space having no core material is generated at the corner portion. For this reason, when resin fittings are exposed to high heat due to a fire or the like, there is a concern that the resin will melt and the corners where the core material will not be placed will melt, causing flames and high-temperature air to penetrate indoors and outdoors. was there.

As described above, a fitting having improved fire protection performance in a portion where the core material of the frame body is not arranged is desired.

The corner portion 101 includes a portion in which the end face forming the V-shape of the lower end portion of the mullion 16 is abutted and joined to the V-shaped end face of the lower frame 12.

Further, as shown in FIG. 6, the mullion core member 16e is provided along the longitudinal direction of the mullion 16, and the end faces of the mullion core member 16e are substantially orthogonal to the longitudinal direction. The mullion core material 16e has a length that does not extend to the inside of the lower frame 12 to be joined to the mullion 16.
Similarly, the lower frame core member 12d is provided along the longitudinal direction of the lower frame 12, and the end faces of the lower frame core member 12d are substantially orthogonal to the longitudinal direction. The lower frame core material 12d does not extend to the lower end of the V-shape of the mullion 16. That is, the lower frame core material 12d has a length that does not extend to the inside of the mullion 16 joined to the lower frame 12.

Here, the length that does not extend to the inside of the mullion 16 or the lower frame 12 means that the mullion core 16e is inside the lower frame 12 so as to reach the virtual extension line of the lower frame core 12d in the lower frame 12. It means not to enter. Further, the lower frame core material 12d means that the lower frame core material 12d does not enter the inside of the mullion 16 so as to reach the virtual extension line of the mullion core material 16e within the mullion 16.

The lower frame core material 12d and the cubic core material 16e are not directly joined in the corner portion 101 of the frame body 10. The lower frame core material 12d and the cubic core material 16e are connected by a frame-side corner metal fitting 46 arranged along the corner portion 101. Specifically, the frame-side corner metal fitting 46 has a substantially L-shaped side view, and is fixed to the inner side surfaces of the mullion 16 and the lower frame 12 with screws. The frame-side corner fitting 46 is formed by joining one side of the L-shape to the internal mullion core material 16e and the other side to the lower frame core material 12d via a resin mullion 16 and a lower frame 12. , The lower frame core material 12d and the mullion core material 16e are connected. Therefore, a gap S is formed inside the corner portion 101 in which the end portion of the lower frame core material 12d and the end portion of the quadrangular core material 16e are not arranged.

Although not shown, the mullion 16 is formed in an inverted V shape at the upper end so that the top protrudes upward, and the mullion 16 and the upper frame 11 have been described above. It has the same configuration as the lower end side.

In the fitting 1 of the present embodiment, the heating foam material 38 is further provided on the frame side corner metal fitting 46. The heat foaming material 38 is provided so as to expand at a high temperature and fill the gaps between the resins deformed by heat. The heated foaming material 38 is provided on both the surface of the frame-side corner fitting 46 on the mullion 16 side and the surface of the lower frame 12 side. The heated foaming material 38 has a continuous sheet shape from the surface on the mullion 16 side to the surface on the lower frame 12 side.

FIG. 7 is a partially enlarged cross-sectional view of the fitting 1. As shown in FIG. 7, the mullion 16 has a substantially T-shaped shape in a cross-sectional view, and constitutes a central portion 163 that constitutes a vertical axis of the T-shape and a horizontal axis of the T-shape, and is on the indoor side. It has a surface portion 164 facing the surface.

The heat foaming material 38 is provided at the central portion 163 of the mullion 16 along the inner surface of the first surface 161 and the lower frame 12 on one side of the frame side corner fitting 46 in the finding direction. Further, the heat foaming material 38 is provided at the central portion 163 of the mullion 16 along the inner surface of the second surface 162 and the lower frame 12 on the other side of the frame side corner fitting 46 in the finding direction.
As shown in FIG. 7, the frame-side corner fitting 46 and the heated foaming material 38 are arranged so as to fit in the corner where the central portion 163 and the surface portion 164 intersect.

The same configuration is used on the upper frame 11 side of the mullion 16. Further, the corner metal fittings 46 and the heated foaming material 38 are similarly provided at the corners 101 of the vertical frame 13 on the shoji side, the upper frame 11 and the lower frame 12, and the vertical frame 14 on the FIX side and the upper frame 11 and the lower frame 12. There is.

When the fitting 1 is exposed to high heat, the frame body 10 made of resin is deformed or melted. At this time, as shown in FIG. 7, the metal mullion core material 16e in the mullion 16 and the metal upper frame core material 11d and lower frame core material 12d in the upper frame 11 or the lower frame 12 are made of metal. It is connected by a corner metal fitting 46 made of. However, between the metal mullion core material 16e and the surfaces of the upper frame core material 11d and the lower frame core material 12d on the mullion 16 side, the side wall of the resin constituting the central portion 163 of the mullion 16 is located. This part melts. Therefore, there is room for flames and high-temperature air to penetrate in the expected direction between the mullion core material 16e and the surfaces of the upper frame core material 11d and the lower frame core material 12d on the mullion 16 side to enter the room.

The frame-side corner metal fittings 46 are arranged at each corner portion 101 of the frame body 10, but the upper frame 11, the lower frame 12, the shoji-side vertical frame 13, and the FIX-side vertical frame of the frame body 10 adjacent to the wall surface of the building or the like are arranged. Compared to the frame 14, the mullion 16 lacks a solid structure such as a wall surface, so that it receives heat directly from both sides of the mullion 16 in the left-right direction and is particularly liable to melt.

Further, in each corner portion 101, as described above, the ends of the upper frame core material 11d, the lower frame core material 12d, the vertical frame core material 13d, and the vertical frame core material 14d are substantially orthogonal to the longitudinal direction. It is configured with a square end. The upper frame core material 11d, the lower frame core material 12d, the vertical frame core material 13d, and the vertical frame core material 14d are connected by the frame side corner metal fittings 46, but the vertical frame core material 13d and the vertical frame core material 13d are inside the corner portion 101. A gap S is formed in which the end portion of the frame core material 14d, the upper frame core material 11d, and the end portion of the lower frame core material 12d are not arranged. Therefore, in the gap S, the resin melts, so that flame or high-temperature air easily penetrates.

Here, since the heated foaming material 38 is provided on both sides of the L-shaped corner metal fitting 46 on the frame side from the side surface on the horizontal frame (upper frame 11, lower frame 12) side to the side surface on the mullion 16 side. When the temperature reaches a predetermined temperature, the heated foaming material 38 expands.
