Japanese Patent Laying-Open No. 2015-92060

When the heat-expandable refractory material is provided on the prospective surface of the frame, since the prospective surface of the frame is exposed when the door is opened, the heat-expandable refractory material becomes easy to be visually recognized and the design property is deteriorated.
Also, when foaming the heat-expandable refractory material provided on the prospective surface of the frame to close the gap with the prospective surface of the door, the door side may be warped by heat at the time of fire, and it was attached to the frame There is a possibility of moving from a position facing the thermally expandable refractory material. For this reason, when the heat-expandable refractory material foams and expands, it does not come into contact with the prospective surface of the door, and the gap between the door and the frame cannot be reliably closed, and there is a possibility that sufficient fire prevention performance cannot be secured. is there.

  The objective of this invention is providing the fitting which is excellent in the designability and can improve fire prevention performance.

  The joinery of the present invention includes a joinery frame and a door attached to the joiner frame so as to be openable and closable, and the joinery frame includes a prospective surface along an outer peripheral surface of the door, and the door frame. A resin member is disposed at an indoor side end of the outer peripheral surface of the door body, and the resin member is provided at a position facing the prospective surface of the joinery frame. A first heating and foaming portion containing a thermally expandable material, and a second heating and foaming portion provided at a position facing the indoor-side finding surface of the joinery frame and containing a thermally expandable material. It is characterized by.

In the present invention, since the indoor frame is provided on the joinery frame, the door is provided on the outdoor side so that it can be opened and closed. Since the resin member is disposed on the indoor side end of the outer peripheral surface of the door body, and the first heating foaming portion and the second heating foaming portion that foam in the event of a fire are provided on the resin member, even if the door body heat warps The heating foaming part can be surely foamed toward the frame to reliably close the gap with the joinery frame.
That is, the joinery frame and the door body are engaged so as not to be opened by a latch bolt or a dead bolt provided at a substantially intermediate position in the vertical direction of the door body.
Here, when a fire occurs on the outdoor side, when the outdoor surface becomes hot and the steel plate of the door body is thermally expanded, the door body is warped so that the upper and lower ends move to the indoor side. In this case, since the resin member provided at the indoor side end of the outer peripheral surface of the door is opposed to the prospective surface of the joinery frame and the indoor-side finding surface, the first and second heating foam portions of the resin member are foamed. Therefore, the space between the joinery frame and the door can be reliably closed.
In addition, when a fire occurs on the indoor side, when the indoor surface becomes hot and the steel plate of the door is heated, the door warps so that the upper and lower ends move to the outdoor side.

On the other hand, in this invention, since the resin member is provided in the indoor side edge part of the outer peripheral surface of a door body, even if the upper and lower ends of a door body move to the outdoor side, the indoor side edge part is a joinery frame. There is a high possibility that it remains in the position facing the prospective surface. Therefore, since the resin member of the door is opposed to the prospective surface of the joinery frame and the indoor-side finding surface, when the first and second heating foam parts of the resin member are foamed, the gap between the joinery frame and the door surely is ensured. Can be closed. Therefore, fireproof performance can be improved.
Furthermore, since the resin member is provided on the door body side, the design is not deteriorated even if the joinery frame is exposed when the door body is opened. In addition, since the resin member can be configured so as to be covered with the indoor-side finding surface of the joinery frame and not exposed to the indoor side when the door is closed, the designability is lowered even when the door is closed. There is no. Therefore, it is possible to provide a joinery that is excellent in design and can improve fireproof performance.

In the joinery of the present invention, a tight material capable of contacting the indoor surface of the door is attached to the indoor-side finding surface of the joinery frame, and the second heating foaming portion is at least a position facing the tight material Is preferably provided.
According to the present invention, when the second heating foaming part expands and expands, the tight material can be covered, and the fire-resistant performance can be improved by preventing and suppressing the burning of the tight material.
Further, since the tight material can be covered with the second heating foam material, it is not necessary to use a non-combustible tight material composed of a non-combustible material as the tight material, and it can be composed of a general material such as PVC. . The nonflammable tight material may have a greater repulsive force than a general tight material, which may hinder the closing of the door. On the other hand, in this invention, a tight material can be comprised with PVC etc. and a door can be closed reliably.

In the joinery of the present invention, the resin member includes a prospective surface portion that faces the prospective surface of the joinery frame, a finding surface portion that faces the indoor-side finding surface of the joinery frame, and a connection that connects the prospective surface portion and the finding surface portion. At least the prospective surface portion, the connecting portion, and the finding surface portion are made of a resin material containing a thermally expandable material, and the first heating foam portion is constituted by the prospective surface portion, and the finding surface portion It is preferable that the second heating foaming part is constituted by the above.
According to the present invention, in addition to the prospective surface portion that is the first heating foaming portion and the finding surface portion that is the second heating foaming portion, the connecting portion disposed therebetween can also be foamed and expanded. A space between the space blocked by the heating foaming portion and the space blocked by the second heating foaming portion can also be blocked. Therefore, the gap between the joinery frame and the door can be closed more reliably, and the fireproof performance can be improved.

In the joinery of the present invention, the door body includes a core material, a metal outdoor surface material provided on the outdoor surface of the core material, and a metal indoor surface material provided on the indoor surface of the core material. The indoor surface material is bonded to the indoor surface of the core material, the outer peripheral surface portion formed continuously with the indoor surface portion and along the outer peripheral surface of the core material, An indoor finding surface portion extended from the outer peripheral surface portion to the prospective surface side of the joinery frame, and the resin member is disposed in a recess defined by the outer peripheral surface portion and the indoor finding surface portion. Is preferred.

A resin member 8 is mounted in the recess 57 at the peripheral edge of the door 5. The shape of the resin member 8 will be described with reference to FIG. In FIG. 4, the lock 6 is omitted.
The resin member 8 extends from the outdoor surface portion 81 and the outer peripheral side end portion of the outdoor surface portion 81 to the indoor side and faces the prospective surfaces (the lower surface portion 113, the upper surface portion 213, the side surface portions 313 and 413) of the door frame 2. The prospective surface portion 82, a finding surface portion 83 that faces the holding piece portions 122, 222, 322, and 422, and a connecting portion 84 that is formed in a circular arc shape and connects the prospective surface portion 82 and the finding surface portion 83.

  In the outdoor surface part 81, the thickness dimension (dimension in the prospective direction) of the end part in contact with the heat insulating member 60 is made larger than other parts of the outdoor surface part 81. For this reason, the outdoor surface part 81 of the resin member 8 arrange | positioned at the upper surface of the door 5, the lower surface, and the side surface by the side of suspension is press-fitted in the clearance gap between the outdoor finding surface parts 514A-514C and the indoor finding surface parts 523A-523C. The outdoor surface portion 81 of the resin member 8 disposed on the side surface on the door-end side is press-fitted between the indoor side end portion of the edge member 7 and the indoor finding surface portion 523D.

  A groove 831 is formed on the outdoor surface of the finding surface portion 83 (the surface facing the indoor finding surface portions 523A to 523D). Each resin member 8 is attached to the door 5 by inserting a locking piece of a small cap (not shown) into the groove 831.

Such a resin member 8 sets the dimensions in the prospective direction (Z-axis direction) from the outdoor surface portion 81 to the finding surface portion 83 based on the prospective dimensions of the outer peripheral surface portions 522A to 522D, so that the finding surface portion 83 becomes the indoor surface portion. It is set to be substantially flush with 521. Therefore, no step is generated between the indoor surface portion 521 and the finding surface portion 83.
Further, the resin member 8 provided in the peripheral portions 520A to 520C is provided in the direction of finding from the prospective surface portion 82 to the tip portion of the finding surface portion 83 (in the Y axis direction in the resin member 8 provided above and below the door 5 and on the suspension base side). By setting the dimension of the resin member 8 in the X-axis direction) based on the dimensions from the outer peripheral surface portions 522A to 522C of the indoor surface material 52 to the outdoor predicted surface portions 513A to 513C of the outdoor surface material 51, the expected surface portion 82 It is set to be substantially flush with the outdoor prospective surface portions 513A to 513C. For this reason, no step is formed between the prospective surface portions 513A to 513C and the prospective surface portion 82.

The resin member 8 having such a structure is manufactured by extruding a heat-expandable resin material in which a heat-expandable material such as heat-expandable graphite is mixed in a polyurethane resin or an epoxy resin. When heated to a temperature, the entire resin member 8 foams and expands.
At this time, the prospective surface portion 82 is provided to face the prospective surfaces (the lower surface portion 113, the upper surface portion 213, the side surface portions 313 and 413) of the door frame 2, and foams toward the prospective surface of the door frame 2. For this reason, the 1st heating foaming part is comprised by the prospective surface part 82. FIG.
The finding surface portion 83 is provided facing the indoor-side finding surface of the door frame 2, that is, the holding piece portions 122, 222, 322, and 422 to which the tight materials 15, 25, 35, and 45 are attached. Foam toward the indoor side of the surface. For this reason, the second heating foaming portion is constituted by the finding surface portion 83.
Since the connecting portion 84 is curved in an arc shape, the connecting portion 84 foams in an oblique direction intersecting the prospective direction and the finding direction. For this reason, the connection part 84 foams toward the heat insulating materials 13, 33, 43, for example.

  The fire prevention structure between the door 5 and the door frame 2 will be described with reference to FIGS. 5 and 6 showing a state in which the resin member 8 is foamed between the door tip side of the door 5 and the vertical frame 40. 5 shows an outdoor side heating state in which the test is performed by heating the outdoor side of the door 5, and FIG. 6 shows an indoor side heating state in which the test is performed by heating the indoor side of the door 5.

As shown in FIG. 5, in the outdoor side heating state, the outdoor face material 51 and the like are thermally expanded, so that the upper end and the lower end of the door 5 warp so as to move indoors. Since the middle part in the vertical direction of the door 5 is latched to the door frame 2 by latch bolts 6A and dead bolts, the middle part in the vertical direction of the door 5 is not moved when the door 5 is thermally warped. First, the upper end and lower end move.
For this reason, the upper end part and lower end part of the door 5 move to the indoor side, and the gaps with the tight materials 15, 25, 35, 45 are narrower than in the case where they are not thermally warped.
When the resin member 8 expands by foaming, the gap between the door 5 and the prospective surface of the door frame 2, or the gap between the door 5 and the tight members 15, 25, 35, 45 and the holding pieces 122, 222, 322, 422. Is closed by the foamed resin member 8. Since the resin member 8 also covers the tight materials 15, 25, 35, 45, the heat insulating materials 13, 33, 43, the heat insulating member 60, and the like, the tight materials 15, 25, 35, 45, the heat insulating materials 13, 33, 43, the heat insulating materials. It is possible to prevent the member 60 from being burned out.

As shown in FIG. 6, in the indoor heating state, the indoor face material 52 and the like are thermally expanded, so that the upper end and the lower end of the door 5 move to the outdoor side with respect to the middle portion in the vertical direction of the door 5. Warp like so. For this reason, the clearance gap between the upper end part and lower end part of the door 5, and the tight materials 15, 25, 35, and 45 becomes wide compared with the case where it does not heat-warp.
When the resin member 8 expands by foaming, the gap between the door 5 and the prospective surface of the door frame 2, or the gap between the door 5 and the tight members 15, 25, 35, 45 and the holding pieces 122, 222, 322, 422. Is closed by the foamed resin member 8. In addition, the tight materials 15, 25, 35, and 45 may be melted to heat the indoor side, but the resin member 8 foams and closes the gap between the door 5 and the door frame 2, thus ensuring fire prevention performance. can do.
Moreover, since the resin member 8 also covers the heat insulating materials 13, 33, 43, the heat insulating member 60, and the like, the heat insulating materials 13, 33, 43, and the heat insulating member 60 can be prevented from being burned out.

  As described above, since the resin member 8 containing thermally expandable graphite foams and expands in the event of a fire, the gap between the door 5 and the door frame 2 can be closed, and the necessary fireproof performance is ensured in the entrance door 1. The

[Effects of First Embodiment]
According to this embodiment, in addition to the effects obtained by the present invention, the following effects can also be achieved.
Since the resin member 8 includes the finding surface portion 83 that is the second heating and foaming portion, the tight materials 15, 25, 35, and 45 can be covered with the foaming and expanded finding surface portion 83. For this reason, it is not necessary to use a nonflammable tight material, and when the door 5 is closed, it is possible to prevent the nonflammable tight material having a limited hue from being exposed to the indoor side and deteriorating the design.

  The resin member 8 includes a prospective surface portion 82 that is a first heating foaming portion and a finding surface portion 83 that is a second heating foaming portion, and a connection portion 84 disposed between them. Since it is configured to be able to foam in an oblique direction by being curved in an arc shape, a space between the space blocked by the prospective surface portion 82 and the space blocked by the finding surface portion 83 can also be blocked. Therefore, the heat insulating materials 13, 33 and 43 can be covered with the foamed and expanded connecting portion 84, and the space between the door frame 2 and the door 5 can be more reliably closed, and the fireproof performance can be improved.

  Since the resin member 8 is disposed in the concave portion 57 formed by bending the indoor surface material 52 of the door 5, it is easy to form the concave portion 57 according to the dimensions of the resin member 8. Can be arranged without a step with respect to the indoor surface portion 521 and the outdoor prospective surface portions 513A to 513C.

  In the door 5, since the heat insulation member 60 is arrange | positioned between the outdoor surface material 51 and the indoor surface material 52, it can prevent that the outdoor surface material 51 and the indoor surface material 52 contact directly, and can improve heat insulation performance. Moreover, since the outdoor surface material 51 and the indoor surface material 52 are fastened with the rivet 65, a metal aggregate is provided along the outer peripheral surface of the heat insulation core material 53, and an outdoor surface material and an indoor surface material are provided to a metal aggregate. There is no need to fasten with rivets. Therefore, the door 5 can be configured without providing the metal aggregate, the door 5 can be reduced in weight, and the cost can be reduced.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIG. Note that in the second embodiment, the same or similar components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted or simplified.
The second embodiment is different from the first embodiment in the fastening structure of the outdoor surface material 51 and the indoor surface material 52 and the configuration of the resin member 8.
That is, as shown in FIG. 7, in the door 5 </ b> A of the second embodiment, the outdoor surface member 51 includes an outdoor prospective surface portion 513 </ b> D bent from the outdoor surface portion 511 to the indoor side. In addition, the indoor facing member 52 has an outer peripheral surface portion 522D bent from the indoor surface portion 521 to the outdoor side, and an indoor finding surface portion 523D bent from the outdoor side end portion of the outer peripheral surface portion 522D to the outer peripheral side (door frame 2 side). And an indoor prospective surface portion 524D extended from the indoor finding surface portion 523D to the outdoor side.
And the indoor prospective surface part 524D is arrange | positioned in the outer peripheral side (door frame 2 side) of the outdoor prospective surface part 513D of the outdoor surface material 51, and the outdoor prospective surface part 513D and the indoor prospective surface part 524D are formed by rivets 65A penetrating in the direction of finding them. It is concluded.

The resin member 8A provided on the door 5A includes an outdoor surface portion 81, a prospective surface portion 82, a finding surface portion 83, and a connecting portion 84, and further, a cover portion 85 extending from the outdoor surface portion 81 to the outdoor side, and an outdoor prospective surface portion 513D. And a spacer portion 86 disposed between the indoor prospective surface portion 524D.
The cover portion 85 is provided to face the prospective surface of the door frame 2 and covers the end portions of the outdoor surface material 51 and the indoor surface material 52 of the door 5. The spacer part 86 is arrange | positioned between the outdoor prospecting surface part 513D and the indoor prospective surface part 524D, and prevents these contacting directly. Therefore, the spacer part 86 serves also as the heat insulating member arrange | positioned between the outdoor surface material 51 and the indoor surface material 52 similarly to the heat insulating member 60 of 1st Embodiment.

In the resin member 8 </ b> A, the outdoor surface portion 81, the prospective surface portion 82, the finding surface portion 83, and the connecting portion 84 are formed of a resin containing thermally expandable graphite, similarly to the resin member 8. Moreover, the cover part 85 and the spacer part 86 may be shape | molded with resin containing thermal expansible graphite, and may be shape | molded with resin which does not contain thermal expansible graphite.
If the cover portion 85 is formed of a resin containing thermally expandable graphite, the area that closes the gap between the outer peripheral surface of the door 5 and the prospective surface (side surface portion 413) of the door frame 2 can be increased. Flames and smoke can be blocked more reliably between the frames 2.
If the spacer portion 86 is formed of a resin containing thermally expandable graphite, the space between the outdoor face material 51 and the indoor face material 52 can be reliably closed, and even if gas is generated from the heat insulating core material 53, the gas is outdoors. Outflow between the face material 51 and the indoor face material 52 can be prevented.

  The edge material 7 is attached to the door end side of the door 5A on the outdoor side of the resin member 8A. For this reason, the prospective dimension of the edge material 7 is a dimension shorter than the edge material 7 of 1st Embodiment.

[Effects of Second Embodiment]
According to 2nd Embodiment, there can exist an effect similar to the said 1st Embodiment. Further, since the cover portion 85 and the spacer portion 86 are provided on the resin member 8A, the edge member covering the outer peripheral surface of the door 5A and the heat insulating member disposed between the outdoor surface material 51 and the indoor surface material 52 are formed by the resin member 8A. Can also be used. For this reason, the number of parts of the door 5A can be reduced and the assemblability can be improved.
In addition, since the heat-expandable graphite can be contained in the cover portion 85 and the spacer portion 86, the volume of the expansion material closing the space between the door frame 2 and the door 5 can be increased, and the fireproof performance can be improved.
Furthermore, since the clearance gap between the heat insulation core material 53, outdoor prospective surface part 513D, and indoor prospective surface part 524D can be made small, the heat insulation performance and rigidity of the door 5A can be improved.

In addition, this invention is not limited to the thing of the structure demonstrated by the above embodiment, The modification in the range which can achieve the objective of this invention is contained in this invention.
