Description

  The present invention relates to a joinery.

Conventionally, as a fire prevention structure of a door (joint) such as a door, which is provided at an entrance such as a front door, one disclosed in Patent Document 1, for example, can be cited. This has been proposed as a technique for preventing warpage of a door due to heat and reliably preventing flames and smoke from spreading in the event of a fire.
According to this, by attaching latch locks to at least two locations of the upper end portion and the lower end portion on the open end side of the door pivotally supported by a hinge or the like at one end, these latch locks can be used when the door is closed. Locked by. Moreover, when a fire breaks out, the warp of the door is suppressed by these latch locks, thereby preventing the combustible gas inside the door body from leaking to the outside.

JP2013-19228A

  However, in the one disclosed in Patent Document 1, latch locks are attached to two or more locations (double latch structure, triple latch structure, etc.) to forcibly suppress door warpage due to heat. Therefore, in addition to the increase in the number of parts, there is a problem in that the cost increases due to the increase in the number of processing steps and the number of mounting steps. In particular, the triple latch structure using a fuse latch has a problem that malfunction occurs in the event of a fire in addition to noise.

  An object of this invention is to provide the fitting which can suppress the thermal warp of a door main body by a simple means at the time of a fire.

  The joinery according to the present invention for achieving the above object has the following characteristics.

(1) It is a fitting that includes an inner side surface material, an outer side surface material, and a core material sandwiched between these double-sided materials at least at the door end side, and is openable and closable,
And a thermoplastic member interposed between the core material and the double-sided material.

  According to the invention of (1), in the event of a fire, the thermal warpage of the joinery can be suppressed by the thermoplastic member interposed between the door-end side core material and the double-sided material. Moreover, the heat warp of the door-end side core material is absorbed by the carbonized resin by carbonizing the thermoplastic member.

(2) It is preferable that the joinery is filled with a heat insulating member made of a material that melts by heat in its internal space.
According to the invention of (2), the heat insulating function is lost when the heat insulating member is melted by heat, and the increase in the temperature difference between the double-sided materials is suppressed. As a result, the thermal warpage of the face materials is suppressed.

(3) It is preferable that the said thermoplastic member is an elongate member extended along the said core material by the side of a door.
According to the invention of (3), the above effect is more reliably exhibited.

(4) It is preferable that the fitting has a single latch structure in which one latch lock is provided at the door end.
According to the invention of (4), even if it is a single latch structure, heat warping can be sufficiently suppressed. Therefore, by reducing the number of parts, the number of processing steps and the number of mounting steps can be reduced, and the cost can be reduced.

  FIG. 5 is a plan sectional view showing the structure of the side edge of the door body according to this embodiment, and FIG. 6 is a view of the main part of the door body provided with the single latch structure according to this embodiment as seen from the outdoor side. .

As shown in FIG. 5, the buffer member 4i is disposed between the outer surface of the pair of side plate portions 4d1 of the door-end side core member 4d, the outer surface material 4g, and the inner surface material 4a.
And the heat insulation panel 4b is filled in the internal space defined by the door-end side core material 4d and the pair of buffer members 4i, the outer surface material 4g, and the inner surface material 4a. This heat insulation panel 4b is filled over the suspension side core material 4c.

  Further, inward flanges 4i1 are integrally formed at the door end side ends of the pair of buffer members 4i, and are respectively engaged with shoulder portions of the door end side core member 4d. Similarly, inward flanges 4g1 and 4a1 are integrally formed on the door end side end portion (including the hung side end portion) of the outer surface material 4g and the inner surface material 4a, and are respectively engaged with the shoulder portions of the pair of buffer members 4i.

It is a heating foam material attached to.

  Therefore, in assembling the door body 4, first, the suspension side core material 4c, the upper side core material 4e, and the lower side core material 4f are attached to one of the inner surface material 4a and the outer surface material 4g (for example, the outer surface material 4g). Secure with rivets. At this time, the buffer member 4i is attached from both sides of the door-end side core member 4d from a thermoplastic member.

  Next, the heat insulation panel 4b is arrange | positioned inside these core materials 4c-4f. And in the state which has arrange | positioned the heat insulation panel 4b, one (for example, inner surface material 4a) of the other inner surface material 4a and the outer surface material 4g is fixed so that it may cover. At this time, a resin edge may be affixed to the outer surface of the suspension base core 4c. Further, the above-mentioned lock-around parts and electric lock-around parts are attached at appropriate stages as before.

According to the opening device 1 configured as described above, the first to third surrounding core members 11A to 11C provided to surround various component mounting holes in all directions in the door body 4 are provided. Prepared.
Thereby, since the surroundings of the part mounting holes are surrounded by the first to third surrounding core members 11A to 11C in all directions, the combustible gas in the door body 4 leaks outside from the part mounting holes, Inflammation can be prevented.

Moreover, according to the joinery of this embodiment, the interior space of the door body 4 is filled with the heat insulating panel 4b made of a material that melts by heat, and the door-end side core material 4d and the inner surface material 4a adjacent to the heat insulating panel 4b. Further, a buffer member 4i made of a thermoplastic member is interposed between the contact surfaces with the outer surface material 4g.
Thus, in the event of a fire, the cushioning member 4i made of a thermoplastic member interposed between the door-end side core material 4d and the inner surface material 4a and the outer surface material 4g causes the door-end side core material 4d. Thermal sled is absorbed. Moreover, when the buffer member 4i made of a thermoplastic member is carbonized, the heat warp of the door-end side core member 4d is absorbed by the carbonized resin. Moreover, the heat insulation function is lost when the heat insulation panel 4b is melted by heat, and the increase in the temperature difference between the inner surface material 4a and the outer surface material 4g is suppressed. As a result, heat warpage of these face materials is suppressed. The Therefore, the thermal warp of the door body 4 can be suppressed by a simple means of installing the buffer member 4i made of a thermoplastic member and changing the material of the heat insulating panel 4b, and the cost is not increased.

  Moreover, as shown in FIG. 6, even in the door body 4 according to the present embodiment having a single latch structure in which one latch lock 60 is provided at the door end, heat warping can be sufficiently suppressed. Compared to a door body with a latch structure or a triple latch structure, the number of parts and the number of installation steps can be reduced by reducing the number of parts, thereby reducing costs.

  As a result, in the event of a fire, it is possible to suppress the thermal warping of the upper and lower parts, particularly at the side edge of the door body 4, with simple means, and to suppress the leakage of flame from the thermal sled portion.

  Needless to say, 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.
