Japanese Utility Model Publication No. 60-23432

  However, in the joinery of Patent Document 1, the door is warped during a fire and is separated from the tight material, and a gap is formed between the frame and a flame may be ejected from the gap to spread.

  Then, an object of this invention is to provide the fitting which can suppress the thermal warp of the direction from which a tight material leaves | separates, and can prevent that a clearance gap produces between a door and a frame.

  The invention according to claim 1 is provided with a frame, a door, and a tight material, the frame has a door tip side finding surface portion facing the door finding surface on the door tip side, and the tight material is a door of the frame. It is provided between the front-side finding surface part and the door, and the door has a front panel, a back panel, and a door-side rib arranged between these panels. Is a joinery characterized in that a plurality of slits in the left-right direction are provided at intervals in the vertical direction in the middle in the longitudinal direction of the door-end skeleton.

  According to the first aspect of the present invention, since a plurality of slits in the left and right direction are formed vertically on the finding surface on the tight material side of the door toe bone, when thermal elongation occurs in the door toe bone The slit absorbs the thermal elongation of the tight surface on the side of the tight material and suppresses thermal warpage in the direction away from the tight material. This prevents a gap from being generated between the door and the frame.

Each tight material 55, 57, 59, 61 is made of flame-retardant silicon.

Here, the thermal expansion refractory material will be described.
As shown in FIG. 1, the door frame 39 has a first thermal expansion refractory material 32 a extending in the longitudinal direction of the door frame 39 at a position close to the door edge tight material 55 on the inner peripheral prospective surface. It foams by the heat of the fire and closes the space between the doors of the opposing doors 5.
A second thermal expansion refractory material 32b is provided in the door butt frame 41 at a position close to the door butt side tight material 57 on the inner peripheral side prospective surface in the longitudinal direction of the door butt frame 41. It foams by heat and closes between the doors of the door 5 facing each other.
As shown in FIG. 3, the upper frame side finding surface portion 51 of the upper frame 43 is provided with a third thermal expansion refractory material 32 c above the upper tight material 59, and the lower frame side finding surface portion 53 of the lower frame 45 is provided on the lower frame side finding surface portion 53. The fourth thermal expansion refractory material 32d is provided on the lower side of the lower tight material 61 over the longitudinal direction of the corresponding frame, and foams due to the heat of the fire, so that the upper and lower ends of the facing door 5 are opposed to each other. Close the gap.
Further, a fifth thermal expansion refractory material 32e is provided on the outdoor side wall 63 of the upper frame 43 along the longitudinal direction of the upper frame 43, and foams due to the heat of the fire. Block between 43 and the upper end of the door 5.
In addition, in the hollow of the lower frame 45, the sixth thermal expansion refractory material 32f that foams due to the heat of the fire and closes the opposing drain holes is provided at the left and right ends of the lower frame 45.
As shown in FIG. 1, the door 5 is provided with a seventh thermal expansion refractory material 32 g facing the door-end frame 39 on the outdoor side of the door-side expected surface 65, and is foamed by the heat of the fire. The space between the door frame 39 and the outdoor side is closed.
An eighth thermal expansion refractory material 32 h facing the door bottom frame 41 is also provided on the door bottom side prospective surface 67 of the door 5, and foams by the heat of the fire to close the space between the door bottom frame 41.

Next, the effect of the fitting 1 concerning this Embodiment is demonstrated.
Referring to FIGS. 1 and 4, when a fire occurs indoors, there is a temperature difference between the outdoor side finding surface and the indoor side finding surface that causes the indoor side finding surface to become hot, and the indoor side finding surface heats up. Since the elongation becomes larger than the outdoor-side finding surface, the door-end force frame 11 is curved so as to project the middle in the vertical direction toward the indoor side, and the upper end portion and the lower end portion of the door-end force frame 11 are tight on the door-end side. It tries to warp in a direction away from the material 55.
However, in the present embodiment, since a plurality of slits 21 in the left-right direction are formed in the door-end side of the door-side rib material 11 on the door-end side tight material 55 side, the door-end side of the door-end rib 11 When thermal elongation occurs on the tight 55 side, the slit 21 absorbs the thermal elongation of the door-side side tight material 55 side finding surface, and suppresses thermal warping in the direction in which the door-side side tight material 55 is separated. This prevents a gap from being generated between the door 5 and the frame 3.

Further, the door-end frame 39 is provided with a first thermal expansion refractory material 32 a in the vicinity of the door-end side tight material 55, and the upper and lower portions on the door-end side of the door 3 are separated from the door-end side tight material 55. Even in this case, the first thermal expansion refractory material 32a foams and closes between the door-end frame 39 and the door-end side of the door 5, and a gap is generated between the door-end side of the door 5 and the door-end frame 39. To prevent.
The door end skeleton 11 is a hollow material, and a lower reinforcing member 29a and an upper reinforcing member 29b are provided in the upper and lower portions of the door end skeleton 11 at positions where the slit 11 is straddled. Even if the slit 21 is formed in the door end skeleton 11, a predetermined strength such as the wind pressure strength of the door 5 can be secured.
Since the vertical reinforcing material 31 made of steel, which is less prone to heat warp than the aluminum door-end skeleton 11, is provided adjacent to the door-end skeleton 11. Further suppression is possible.
In addition, since the door butt skeleton 13 is fixed at three places in the vertical direction by the hinge 37, even if it receives heat from the indoor side of the door 3, warpage due to thermal expansion hardly occurs.
Since the slit 21 of the door end skeleton 11 is formed up to an intermediate position between the indoor side finding surface 11a and the left and right prospective surfaces 11b and 11c, the door is compared with the case where it is formed only on the indoor side finding surface 11a. Warpage due to thermal elongation of the leading bone 11 can be effectively suppressed.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.
For example, the number of slits 21 provided on the door end skeleton 11 is not limited to six, and may be two, three, or ten, and the number is not limited. Further, the width W of the slit 21 may be 2 mm or 5 mm, and is not limited.
The slit 21 is not limited to being provided from the indoor side finding surface 11c of the door end skeleton 11 to the prospective surfaces 11b and 11c, but may be provided only on the indoor side finding surface 11c.
The joinery 1 is not limited to a door having a flash door, but may be a door or a sliding door. In this case, it is preferable that the slit 21 is provided in the door toe wall in place of the door toe skeleton 11 and the door toe wall is hidden with a decorative material. Moreover, when the fitting 1 is a sliding door, it is preferable to provide the slit 21 also in the door bottom side wall in addition to the door end wall.
The door end skeleton 11 is not limited to a rectangular tube shape, and may have a U-shaped cross section, and is not limited to a hollow shape.
