JP 2012-122303 A

  By the way, in the sash described in Patent Document 1, when the rigidity yield point of the lower frame that rises due to heat during a fire or the like is lowered, the lower frame may not be able to support the vertical load of the shoji and may be thermoplastically deformed. . When the lower frame is deformed in this way, the positional relationship between the frame and the shoji may deviate from a predetermined position, and the fireproof performance may be reduced. Eventually, the shoji may fall out of the frame body due to the deformation of the lower frame, and there is a possibility that the fireproof performance cannot be exhibited.

  The objective of this invention is providing the fitting which can interrupt | block a drainage path | route based on the heat | fever at the time of a fire, etc., and can exhibit fireproof performance stably.

And the vertical load from a face material can also be supported by supporting the upper part of a lower frame with the finding piece part of a reinforcing material. Therefore, even if the rigid yield point of the lower frame, which rises in temperature due to heat in the event of a fire, decreases and the vertical load of the face material cannot be supported at the upper part of the lower frame, the reinforcing material supports the vertical load from the face material. Can be shared. As a result, the lower frame is reinforced by the reinforcing material even if the rigid yield point is lowered, and thermal deformation is suppressed, so that an appropriate positional relationship between the frame body and the face material can be maintained, and the predetermined fireproof performance is stable.

In the joinery of the present invention, it is preferable that the reinforcing member includes an attachment piece portion provided on the indoor side with respect to the finding piece portion, and the foam material is attached to the attachment piece portion.
According to such a configuration, since the foam material is attached to the attachment piece, the positional relationship between the reinforcing material and the foam material is constant. For this reason, a foaming material can be reduced to the minimum quantity which can block | close a drainage part.

In the joinery of the present invention, the reinforcing member includes a prospective piece portion provided on the indoor side with respect to the finding piece portion, and a mounting piece portion provided on the indoor side with respect to the finding piece portion, The drainage portion of the finding piece portion is located between the prospective piece portion and the attachment piece portion, and the prospective piece portion has a drainage portion that allows the drainage path to communicate with the attachment piece portion. It is preferable that the foam material is attached at a position where foaming is possible toward the drainage portion of the prospective piece portion.
According to such a configuration, the foamed material heated in the event of a fire or the like foams, and in the process of foaming from the mounting piece part toward the prospective piece part and closing the drainage part of the prospective piece part, It is also possible to close the drainage portion of the finding piece portion located between the attachment piece portion and the prospective piece portion. For this reason, the foaming material which plugs the drainage part of the finding piece part and the drainage part of the prospective piece part can be made common, and the drainage path can be blocked efficiently by using a small amount of foaming material.
In addition, the foam material attached to the attachment piece part is disposed at a position where it foams between the attachment piece part and the prospective piece part and closes each drainage part of the reinforcing material. It only presses the material and hardly presses the lower frame itself.

It is continuously connected to the end.

  The attachment portion 225 is formed to extend downward from a connecting portion between the lower surface portion 222 and the indoor side surface portion 224, and is attached to the building frame via screws.

  As shown in FIG. 3, the lower frame 22 configured as described above has a drain hole 229 formed between the outer rail 227 and the inner rail 228, a hollow portion 226, and a lower frame drain hole 230. A drainage channel 231 for draining is provided. The drainage path 231 is schematically represented by arrows shown in FIGS.

The lower frame 22 is provided with the reinforcing material 5 and the foam material 6.
The reinforcing member 5 is formed to extend in the left-right direction so as to be approximately equal to the size in the left-right direction of the shoji 3, and is disposed at a position below the shoji 3 in the closed state of the sliding window 1. The reinforcing member 5 is formed of an extruded aluminum material, and includes a finding piece portion 51, a prospective piece portion 52, and a mounting piece portion 53 as shown in FIGS. The outdoor end portion of the prospective piece portion 52 is connected to the upper portion of the finding piece portion 51, and the outdoor end portion of the mounting piece portion 53 is connected to the lower portion of the finding piece portion 51. That is, the finding piece portion 51, the prospective piece portion 52, and the mounting piece portion 53 are integrally formed.

  The finding piece portion 51 is formed so as to extend in the finding direction (vertical direction) of the reinforcing member 5 and has a slightly smaller finding direction size than the vertical dimension from the upper surface portion 221 to the lower surface portion 222 of the lower frame 22. Is set. On the lower side of the finding piece 51, drain holes 511 are provided as a plurality of rectangular drain holes. A plurality of such drain holes 511 are formed side by side at a predetermined interval in the left-right direction.

The prospective piece portion 52 is formed so as to extend from the upper portion of the finding piece portion 51 toward the indoor side in the prospective direction of the reinforcing member 5 (inside and outside the room). The prospective piece part 52 is set to a prospective direction dimension that is slightly shorter than the distance dimension in the indoor / outdoor direction from the screw hole forming part 221 </ b> A to the indoor side surface part 224. The prospective piece portion 52 is provided with a plurality of rectangular drain holes 512.
The drain hole 512 has a shape corresponding to the drain hole 229. A plurality of such drain holes 512 are formed side by side at a predetermined interval in the left-right direction.

  The attachment piece 53 is formed to extend from the lower part of the finding piece 51 toward the indoor side in the prospective direction of the reinforcing member 5. The attachment piece 53 is formed to extend substantially parallel to the prospective piece 52, and the attachment piece 53 is set to a prospective dimension shorter than the prospective dimension of the prospective piece 52. Therefore, the front end of the attachment piece 53 on the indoor side is located on the outdoor side of the front end of the prospective piece 52 on the indoor side. Further, the attachment piece 53 is arranged to face the prospective piece 52 in the vertical direction.

As shown in FIG. 3, the reinforcing member 5 configured as described above is inserted into the hollow portion 226 from the left and right end surface openings of the hollow portion 226 of the lower frame 22 and is positioned on the drainage path 231.
In the reinforcing member 5, the finding direction size of the finding piece portion 51 and the expecting direction size of the expecting piece portion 52 are set to be slightly shorter than the interval sizes in the vertical direction and indoor / outdoor direction of the hollow portion 226 of the lower frame 22. Therefore, the insertion work to the hollow part 226 can be performed easily.
Further, the positioning of the reinforcing member 5 can be easily performed by bringing the finding piece portion 51 into contact with the screw hole forming portion 221A and bringing the prospective piece portion 52 into contact with the upper surface portion 221. Accordingly, the reinforcing member 5 can be easily positioned at the time of screwing to the lower frame 22 of the reinforcing member 5.
The prospective piece portion 52 is screwed to the upper surface portion 221 of the lower frame 22 at a position deviated from the drain hole 512 in the left-right direction, and is in close contact with the upper surface portion 221. The prospective piece 52 is located below the drain hole 229 and on the indoor side of the lower frame drain hole 230. Therefore, the main body portion of the prospective piece portion 52 is disposed at a position where the drainage path 231 is blocked between the drain hole 229 and the lower frame drain hole 230. The plurality of drain holes 512 formed in the prospective piece portion 52 are arranged so as to overlap with the plurality of drain holes 229, respectively, and the drain passage 231 is formed between the drain hole 229 and the lower frame drain hole 230. Communicate.

  The front end of the prospective piece portion 52 on the indoor side is disposed close to the upper portion of the indoor side surface portion 224 and is located on the indoor side with respect to the lower end of the indoor side surface portion 224. Moreover, the continuous part of the finding piece part 51 and the prospective piece part 52 is in contact with the screw hole forming part 221A on the outdoor side. Therefore, even if the prospective piece portion 52 is separated downward from the upper surface portion 221 due to the drop of screws or the like, the reinforcing member 5 has the prospective piece portion 52 on both the screw hole forming portion 221A and the inclined surface of the indoor side surface portion 224. It will be in the state which contacted and the position in the indoor / outdoor direction of the reinforcing material 5 is maintained.

The finding piece portion 51 is disposed below the outer rail 227 in a state where the reinforcing member 5 is screwed to the upper surface portion 221. The finding piece portion 51 is located farther inward of the indoor side than the outdoor side surface portion 223, and is located further out of the drain hole 229 and more indoor than the lower frame drainage hole 230. . Therefore, the main body portion of the finding piece portion 51 is disposed at a position where the drainage path 231 is blocked between the drain hole 229 and the lower frame drainage hole 230. The plurality of drain holes 511 formed in the finding piece 51 communicate the drain path 231 between the drain hole 229 and the lower frame drain hole 230.
In this way, the finding piece portion 51 arranged in the hollow portion 226 can be used, for example, even if the heated upper surface portion 221 cannot support the vertical load of the shoji 3 and is thermally deformed. The piece 53) is in contact with the lower surface 222, and the finding piece 51 is arranged at a position where the upper surface 221 can be supported. For this reason, the vertical load of the shoji 3 can be found and supported by the piece portion 51, and thermal deformation of the upper surface portion 221 beyond a predetermined level can be suppressed.
The attachment piece 53 is disposed slightly apart from the lower surface portion 222.

The foam material 6 is composed of a rectangular expanded graphite sheet. The foam material 6 is attached to the upper surface of the attachment piece 53. For this reason, the foam material 6 is disposed so as to expand upward along the found piece 51 by the foaming.
The plurality of foam materials 6 are respectively arranged at positions corresponding to one drain hole 511 and three drain holes 512 arranged in the left-right direction, and three foam holes arranged in the left-right direction with the one drain hole 511 at the time of foaming. 512 can be closed.

[Operation of First Embodiment]
The drainage path 231 is shut off in the event of a fire or the like as follows.
When the temperature of the hollow portion 226 rises to a predetermined level or more based on heat at the time of a fire or the like, the foam material 6 foams and expands upward from the attachment piece 53 side toward the prospective piece 52. At this time, since the foam material 6 expands along the finding piece portion 51, the entire drainage hole 511 formed in the lower portion of the finding piece portion 51 is closed at the initial stage of expansion, and the drainage path 231 is quickly blocked. . Subsequently, due to further expansion of the foam material 6, the drain hole 512 of the prospective piece portion 52 is closed, and the drain path 231 is more reliably blocked. In this way, the drainage path 231 is blocked.

The reinforcement of the lower frame 22 in the event of a fire or the like is performed as follows.
When the temperature of the upper surface portion 221 of the lower frame 22 rises due to heat at the time of a fire or the like and the rigidity yield point decreases, if the vertical load of the shoji 3 cannot be supported by the upper surface portion 221, the upper surface portion 221 Some thermal deformation occurs. When this thermal deformation occurs, the finding piece portion 51 of the reinforcing member 5 moves slightly downward and contacts the lower surface portion 222. In this state, the finding piece portion 51 supports the vertical load of the shoji 3 via the outer rail 227 and the upper surface portion 221.
Thus, the reinforcing material 5 reinforces the lower frame 22 and suppresses thermal deformation of the lower frame 22.

[Effect of this embodiment]
(1) The drainage path 231 can be blocked by closing the drainage holes 511 and 512 formed in the reinforcing member 5 by foaming of the foaming material 6.
Further, even if the rigid yield point of the lower frame 22 that rises in temperature due to heat during a fire or the like decreases and the upper surface portion 221 cannot support the vertical load of the shoji 3, the upper surface portion 221 is supported by the finding piece portion 51. Thus, the vertical load from the shoji 3 can be supported, and the support of the vertical load can be shared by the upper surface portion 221 and the finding piece portion 51. As a result, thermal deformation of the lower frame 22 is suppressed, an appropriate positional relationship between the lower frame 22 and the shoji 3 can be maintained, and predetermined fireproof performance can be stably exhibited.
Further, by attaching the foam material 6 to the reinforcing material 5 itself having the drain holes 511 and 512, the reinforcing material 5 and the foam material 6 can be handled as one unit. For this reason, the reinforcing material 5 and the foam material 6 can be easily installed on the lower frame 22.
(2) Both the drain holes 511 and 512 can be blocked by foaming of the common foaming material 6 heated in the event of a fire or the like, and the drain path 231 can be blocked more reliably.
Specifically, in the process of foaming from the attachment piece 53 toward the prospective piece 52 by one foamed material 6 that is heated and foamed in the event of a fire or the like, between the attachment piece 53 and the prospective piece 52. One drainage hole 511 located at can be closed. Thus, by closing the drain holes 511 before the three drain holes 512 are blocked, it is possible to effectively and quickly prevent the external flame from entering the inside.
Further, the foam material 6 that expands toward the prospective piece portion 52 can block the drain hole 511 and the drain hole 512 since it can block the drain hole 511 and then the three drain holes 512. The foam material 6 can be shared, and the drainage path 231 can be efficiently blocked even if a small amount of the foam material 6 is used. The foam material 6 attached to the upper surface of the attachment piece portion 53 is disposed at a position where it foams between the attachment piece portion 53 and the prospective piece portion 52 and closes the drain holes 511 and 512 of the reinforcing material 5. The drainage hole 229 of the lower frame 22 and the lower frame drainage hole 230 are not provided at positions that directly close the drainage hole 229 or the lower frame drainage hole 230. Therefore, even if the foamed material 6 is foamed by heating, the reinforcing material 5 is only pressed by the foamed foamed material 6 and the lower frame 22 itself is hardly pressed. For this reason, it is possible to eliminate the risk of inducing thermal deformation of the lower frame 22 in a state where the rigid yield point is lowered by heat during a fire or the like by foaming of the foam material 6.
Furthermore, since the foam material 6 is attached to the attachment piece 53, the positional relationship between the reinforcing material 5 and the foam material 6 is constant. For this reason, the foam material 6 can be reduced to the minimum amount that can close the drain holes 511 and 512.
In addition, in order to reliably close the drain hole 512, which is the expansion arrival point of the foam material 6, an amount of the foam material 6 that can be expanded to an upper position beyond the drain hole 512 is required. However, in this embodiment, even if the amount of the foam material 6 is reduced, the drain hole 511 can be closed and the intrusion of the flame can be prevented.
(3) Even if the rigid yield point of the lower frame 22 that rises in temperature due to heat during a fire or the like is lowered, the outer rail 227 to which the vertical load from the shoji 3 is applied most can be found and supported by the piece 51. For this reason, the thermal deformation of the upper surface part 221 based on the vertical load of the shoji 3 can be suppressed, and the lower frame 22 can be prevented from being dropped from the outer rail 227 of the shoji 3 due to thermal deformation.
(4) Since the reinforcing material 5 and the foam material 6 attached to the reinforcing material 5 are accommodated in the hollow portion 226, it is not necessary to add various reinforcing members to the outside of the lower frame 22. It is possible to design the sliding window 1 having a configuration that is not different from that of the joinery in which the reinforcing material 5 is not provided.

  In the above-described embodiment, the size in the direction of finding the found piece 51 is set slightly shorter than the distance in the vertical direction from the upper surface 221 to the lower surface 222 of the lower frame 22. The same length may be set. In this case, the lower end of the finding piece portion 51 of the reinforcing member 5 disposed in the hollow portion 226 contacts the lower surface portion 222.

  In the embodiment, the prospective direction dimension of the prospective piece part 52 is set slightly shorter than the distance dimension in the indoor / outdoor direction from the screw hole forming part 221A to the indoor side surface part 224. For example, it is the same as the distance dimension described above. The length may be set. In this case, the indoor-side tip of the prospective piece portion 52 of the reinforcing member 5 disposed in the hollow portion 226 contacts the indoor side surface portion 224.

  In the embodiment, the reinforcing material 5 is formed to extend in the left-right direction so as to be approximately equal to the size in the left-right direction of the shoji 3, but is not limited to this, and may be formed in various lengths. . For example, the reinforcing member 5 may be formed to extend in the left-right direction so as to be approximately equal to the left-right dimension of the lower frame 22. In this case, the position of the reinforcing member 5 in the left-right direction may be maintained by the vertical frames 24, 25, or angle members (not shown) that connect the vertical frames 24, 25 and the lower frame 22.

  In the above-described embodiment, the reinforcing material 5 is formed of an extruded aluminum material. However, the reinforcing material 5 is not limited to this. For example, the reinforcing material 5 may be made of steel and bent.

In the said embodiment, although the reinforcing material 5 is comprised by the piece piece 51, the prospective piece part 52, and the attachment piece part 53 which were integrally formed, it is not limited to this. For example, the reinforcing piece 5 may be configured by forming the finding piece portion 51, the prospective piece portion 52, and the mounting piece portion 53 as separate members and connecting them with screws or the like.
Moreover, in the said embodiment, although the reinforcing material 5A is comprised by the finding piece parts 51 and 54 and the prospective piece part 52 which were integrally formed, it is not limited to this. For example, the reinforcing piece 5A may be configured by forming the finding piece portions 51 and 54 and the prospective piece portion 52 as separate members and connecting them with screws or the like.

  In the above-described embodiment, the attachment piece 53 may be formed to extend straight and straight to the indoor side, or may be formed to be inclined and extend to the indoor side. Further, the attachment piece portion 53 may be formed to be curved and extend from the lower surface portion 222 along the indoor side surface portion 224. Note that the upper surface of the attachment piece 53 may be formed flat or curved.

  In the said embodiment, although the reinforcing material 5 is comprised including the finding piece part 51, the prospective piece part 52, and the attachment piece part 53, it is not limited to this. For example, the reinforcing member 5 may be configured by omitting the prospective piece portion 52 or may be configured by omitting the attachment piece portion 53. When the configuration of the attachment piece portion 53 is omitted, the foam material 6 is provided in one or both of the finding piece portion 51 and the prospective piece portion 52.
