Description

  The present invention relates to a joinery that supports a face material such as a shoji and a door body so as to be openable and closable with respect to the opening frame, and more particularly, to a joinery having a fire prevention measure between the opening frame and the face material.

  Some of today's joinery has fire prevention measures to prevent the spread of fire in the event of a fire. For example, according to a joinery in which a heating expansion material is disposed on a prospective surface facing a frame in a shoji, the heat expansion material expands when heated in the event of a fire, so that the prospective surface of the frame facing each other and the expectation of wrinkles The gap between the surfaces is closed, and the flame can be cut off to prevent fire spread (see, for example, Patent Document 1).

  As the heat expansion material, a sheet-like material is generally used, and a double-sided tape or an adhesive is used so as to be arranged in a series over the entire circumference of the bag.

  By the way, a cap member is attached to a shoji constructed by assembling a reed between upper and lower ends of a pair of reeds so as to cover the end openings and edges of the reeds. In addition, a latch device and a locking device are arranged on the downside located at the door to the inside of the downside from the opening provided on the door end surface. A hinge device is provided for this purpose.

  Here, in order to improve corrosion resistance and wear resistance, the anodizing treatment is applied to the shoji of the shoji. The surface of the anodized cocoon has good adhesion to the heat expansion material, and the heat expansion material can be disposed without falling off. However, the cap member exposed on the prospective surface of the wrinkle is formed of a resin material, and the adhesiveness with the heat expansion material is not necessarily good. Adhesiveness to the heat expansion material is not considered for the surface of the parts exposed to the expected surface of the hook in the latch device or the locking device. Therefore, a gap may be generated between the heat-expandable material and the adhesive surface. If the heat expansion material in the part where the part is attached, such as a cap member, latch device, locking device, etc. is dropped, the gap between the prospective surface of the frame and the probable surface of the heel even when expanded by heating May not be able to be blocked, and this greatly affects the fire performance of the joinery.

  In view of the above circumstances, an object of the present invention is to provide a joinery that can ensure high reliability in fireproof performance.

In order to achieve the above object, the joinery according to the present invention expands the heat expansion material when heated, thereby closing the gap between the prospective surface of the frame and the prospective surface of the ridge facing each other. In the joinery, at least one of the frame and the heel includes a cover fin portion extending along a direction of finding so as to cover a gap between the prospective surface of the frame and the prospective surface of the heel, and the prospect of the heel The surface is provided with a heat-expandable material only in a portion excluding the component attached so as to be exposed on the prospective surface, and the portion where the component is attached so as to be exposed on the prospective surface of the scissors. The portion where the part is attached so as to be exposed to the prospective surface of the frame and the part where the component is attached to the prospective surface of the frame are opposed to each other. A part in which a heat-expandable material is disposed on a surface facing the gap between the surface and the part is attached so as to be exposed on the prospective surface of the ridge, and the part is attached on the prospective surface of the frame A heating expansion material is disposed on the prospective surface of the frame at a location where the portion is not opposed to the portion .

  According to the present invention, with respect to the part where the component is attached so as to be exposed on the prospective surface of the heel, the heat expansion material disposed on the prospective surface of the opposing frame expands, so that the prospective surface of the frame and the expectation of the heel The gap between the surfaces will be blocked. Therefore, even when parts such as a cap member, a latch device, and a locking device are exposed on the prospective surface of the ridge, the heating expansion material can be reliably disposed on the prospective surface of the opposing frame, and fire prevention High reliability can be ensured in performance.

  According to the present invention, by disposing the heat expansion material in the cover fin portion, the part where the part is attached so as to be exposed to the prospective surface of the heel and the part where the part is attached on the prospective surface of the frame are opposed to each other. Also in the place to do, it becomes possible to block the gap between each other with the heating expansion material.

  Moreover, the present invention is characterized in that, in the joinery described above, a heat expansion material is disposed on the prospective surface of the frame so that an end portion overlaps the heat expansion material disposed on the prospective surface of the heel. The joinery according to claim 1.

  According to this invention, since the heat expansion material provided in the frame and the expansion material provided in the bag are expanded so as to overlap each other, it is possible to more reliably prevent the occurrence of a flame through-hole.

  According to the present invention, with respect to the part where the component is attached so as to be exposed on the prospective surface of the heel, the prospective surface of the frame and the expectation of the heel are caused by the expansion of the heating expansion material disposed on the prospective surface of the opposing frame. The gap between the surfaces will be blocked. Therefore, even when parts such as a cap member, a latch device, and a locking device are exposed on the prospective surface of the ridge, the heating expansion material can be reliably disposed on the prospective surface of the opposing frame, and fire prevention High reliability can be ensured in performance.

The door body 20 cannot be opened even when the engaging protrusion 63 is moved in the immersion direction by the operation 64.

  Furthermore, in the joinery of the present embodiment, a heating expansion material 80 is disposed between the prospective surface located on the outer peripheral side of the housing 25 and the prospective surface of the opening frame 10. The heating expansion material 80 forms a non-combustible sheet that expands by being foamed when heated, such as expanded graphite, and is formed on the prospective surface of the casing 25 or the prospective surface of the opening frame 10. It is arranged. For reference, the heated expansion material 80 applied in the present embodiment has a plate thickness of 1.6 mm and expands about 30 times when heated, but is not limited thereto. It is not something.

  Here, the place where the heat-expandable material 80 is disposed is basically a prospective surface of the casing 25, and it is preferable that the heat-expandable material 80 is bonded with a double-sided tape or an adhesive so as to form a series over the entire circumference. However, as described above, the cap member 40, the upper blade 52 of the hinge device 50, the exterior plate portion 62 of the latch device 60, and the exterior plate portion 72 of the lock device 70 are attached to the prospective surface of the housing 25. Yes. Among these, the cap member 40 is formed of a resin material, and it cannot be said that the adhesiveness with a double-sided tape or an adhesive is good. Further, the upper blade 52 of the hinge device 50, the exterior plate portion 62 of the latch device 60, and the exterior plate portion 72 of the lock device 70 are all formed of metal, but each plate thickness is about 3 mm. Since this is a large level difference between the housing 25 and the prospective surface of the housing 25, a gap may be formed between the heat expansion member 80 and the adhesive surface. That is, when the heat expansion material 80 is disposed all around the prospective surface of the housing 25, the portion adhered to the cap member 40, the upper blade 52 of the hinge device 50, and the exterior plate portion of the latch device 60. 62, There is a risk of causing a situation where the locking device 70 is peeled off from the portion adhered to the exterior plate portion 72.

  Therefore, in the joinery of the present embodiment, as shown in FIG. 1, the opening frame that faces the portions where the cap member 40 and the upper blade 52 of the hinge device 50 are attached on the prospective surface of the housing 25. The heating expansion material 80 is arranged on 10 prospective surfaces. Since the latch receiving member 65 and the lock receiving member 75 are provided at portions facing the exterior plate portion 62 of the latch device 60 and the exterior plate portion 72 of the lock device 70 on the prospective surface of the opening frame 10, FIG. As shown in the figure, the heat expansion material 80 is disposed over the entire length of the surface facing the gap between the prospective surface of the opening frame 10 and the prospective surface of the casing 25 in the cover fin portion 23d of the vertical rod 23. As is clear from FIG. 1, the heating expansion material 80 disposed on the prospective surface of the opening frame 10 is overlapped with the heating expansion material 80 disposed on the prospective surface of the housing 25. It is.

  According to the joinery configured as described above, since the heat expansion material 80 is disposed only in a portion having good adhesiveness in the housing 25 and the opening frame 10, the heat expansion material 80 is peeled off and dropped off. There is no risk of incurring a situation. Moreover, the heating expansion material 80 disposed on the prospective surface of the housing 25, the heating expansion material 80 disposed on the prospective surface of the opening frame 10, and the heating expansion material 80 disposed on the cover fin portion 23 d are surrounded by the periphery of the housing 25. It becomes a series along the direction. Therefore, when a fire occurs or the like is heated to a high temperature state, each heating expansion material 80 expands, so that there is no gap between the prospective surface of the opening frame 10 and the prospective surface of the housing 25 without a gap. As a result, it is possible to provide highly reliable fire prevention performance.

  In addition, in embodiment mentioned above, the hinged door provided with the opening frame 10 and the door body 20 is illustrated, However, It is possible to apply also to the fitting which arrange | positioned the sliding paper so that sliding was possible with respect to the opening frame. . In the embodiment described above in the case of a joinery provided with a door, the example provided with the multilayer glass 30 is illustrated, but it is not always necessary to provide glass.

  In the above-described embodiment, the cap member 40, the upper blade 52 of the hinge device 50, the exterior plate portion 62 of the latch device 60, and the lock device 70 are attached as parts that are exposed to the prospective surface of the bag. Although the exterior plate part 72 is illustrated, other parts may be sufficient and it does not necessarily need to be plural. In addition, a heat expansion material cannot be arrange | positioned also about the screw hole which exists in the prospective surface of a wrinkle, and the grommet attached to this. However, when a heating expansion material that expands about 30 times as in the embodiment is applied, there is no possibility of becoming a flame through-hole at the time of heating expansion even if the heating expansion material is cut to about the width of the heating expansion material. Therefore, it is not necessary to provide a heat expansion material on the prospective surface of the frame facing these screw holes and grommets.

  Furthermore, in the above-described embodiment, the heating expansion material 80 is also disposed in the cover fin portion 23d, but it is not always necessary to provide the heating expansion material in the cover fin portion. In addition, the cover fin part which provides a heat expansion material does not necessarily need to be provided in the collar, and you may arrange | position a heat expansion material to the cover fin part provided in the frame.
