Description
本発明は、引戸と袖壁パネルとを有する建具に関する。 The present invention relates to a joinery having a sliding door and a sleeve wall panel.
玄関引戸等の建具では、引戸の引き込み部分に袖壁パネルを設けた構成がある。例えば特許文献1には、引戸を支持する片引き戸枠と、袖壁パネルを保持する袖壁パネル枠と、これら各枠間に立脚した方立とを備えた構成が開示されている。この構成では、袖壁パネル枠は、方立に取り付けた縦枠を用いて袖壁パネルを保持している。 There is a structure in which a sleeve wall panel is provided in a retracting portion of a sliding door in a fitting such as an entrance sliding door. For example, Patent Document 1 discloses a configuration including a single sliding door frame that supports a sliding door, a sleeve wall panel frame that holds a sleeve wall panel, and a stand that stands between these frames. In this configuration, the sleeve wall panel frame holds the sleeve wall panel using a vertical frame attached in a vertical manner.
ところで、上記のような建具の場合、方立は、その上下端部が上下の枠に支持された支持構造となっている。このため、方立は、枠状に連結された片引き戸枠や袖壁パネル枠よりも火災時に変形し易い状態にある。特に、方立は、長手方向中央付近が支持されていないため、火災時には中央付近が室内側に反って弓状に変形する可能性がある。方立が変形した場合、方立と引戸との間等に室内外方向の貫通孔が形成され、この貫通孔が火炎や煙の通り道となる可能性がある。 By the way, in the case of the joinery as described above, the upright has a support structure in which upper and lower ends are supported by upper and lower frames. For this reason, the vertical is more easily deformed in the event of a fire than the sliding door frame or the sleeve wall panel frame connected in a frame shape. In particular, since the vertical is not supported in the vicinity of the center in the longitudinal direction, there is a possibility that the vicinity of the center is warped indoors and deforms into an arcuate shape in the event of a fire. When the vertical is deformed, a through-hole in the indoor / outdoor direction is formed between the vertical and the sliding door, and this through-hole may become a passage for flames and smoke.
本発明は、上記従来技術の課題を考慮してなされたものであり、防火性能を向上することができる建具を提供することを目的とする。 The present invention has been made in view of the above-described problems of the prior art, and an object thereof is to provide a joinery that can improve fire prevention performance.
本発明に係る建具は、上枠、下枠、戸先側縦枠、及び戸尻側縦枠を有し、建物躯体に固定される開口枠と、前記戸先側縦枠と前記戸尻側縦枠との間となる位置で前記上枠と前記下枠との間に設けられる方立と、前記方立の前記戸尻側縦枠側を向いた内側見込み面に連結される中間縦枠と、前記上枠及び前記下枠に対して長手方向に沿ってスライド可能に支持され、前記上枠、前記下枠、前記戸先側縦枠、及び前記方立によって形成される開口部を開閉可能な引戸と、前記上枠、前記下枠、前記中間縦枠、及び前記戸尻側縦枠によって形成される開口部に保持される袖壁パネルと、を備える建具であって、前記方立の長手方向に沿って設けられた補強材と、前記中間縦枠に取り付けられ、前記補強材を係止することにより該補強材の室内側への移動を規制する係止部材と、を備えることを特徴とする。 The fitting according to the present invention includes an upper frame, a lower frame, a door-end side vertical frame, and a door-end side vertical frame, an opening frame fixed to a building frame, the door-end side vertical frame, and the door-end side A vertical frame provided between the upper frame and the lower frame at a position between the vertical frame and an intermediate vertical frame coupled to an inner prospective surface of the vertical frame facing the door-side vertical frame side. And opening and closing an opening formed by the upper frame, the lower frame, the door-end side vertical frame, and the vertical frame, which is slidably supported along the longitudinal direction with respect to the upper frame and the lower frame. And a sleeve wall panel held in an opening formed by the upper frame, the lower frame, the intermediate vertical frame, and the door bottom side vertical frame, A reinforcing material provided along the longitudinal direction of the reinforcing material and attached to the intermediate vertical frame and locking the reinforcing material to the indoor side of the reinforcing material A locking member for restricting the movement, characterized in that it comprises a.
このような構成によれば、方立に設けた補強材の室内側への移動を中間縦枠に取り付けた係止部材によって規制する。これにより、当該建具の火災時、例えば補強材が熱伸びして中央部が室内側に移動するような弓状の反り変形を生じることを係止部材によって抑制できる。その結果、方立と引戸との間での室内外方向の貫通孔の形成を防止でき、防火性能を向上することができる。 According to such a configuration, the movement of the reinforcing material provided in the vertical direction to the indoor side is restricted by the locking member attached to the intermediate vertical frame. Thereby, at the time of the fire of the said fitting, it can suppress by a locking member that the reinforcing material heat-extends, for example, and produces the bow-shaped curvature deformation that a center part moves indoor side. As a result, it is possible to prevent the formation of a through hole in the indoor / outdoor direction between the vertical and the sliding door, and to improve the fireproof performance.
本発明に係る建具において、前記係止部材は、前記中間縦枠に形成されたねじ孔に螺合したねじであり、前記係止部材は、前記ねじの外周面によって前記補強材を係止する構成としてもよい。そうすると、中間縦枠に対する係止部材の固定作業が容易となる。なお、方立の室外側は引戸によって支持されるため、補強材は加熱された際に室内側へと移動しようとする。そこで、係止部材は、ねじの外周面で補強材を係止するだけで補強材の反り変形を規制することができるため、ねじを補強材に対して螺合させる必要がなく、ねじ穴の形成作業やねじ穴の位置合わせ等も不要となるため、設置作業が一層容易となる。 In the fitting according to the present invention, the locking member is a screw that is screwed into a screw hole formed in the intermediate vertical frame, and the locking member locks the reinforcing material by an outer peripheral surface of the screw. It is good also as a structure. If it does so, the fixing operation | work of the latching member with respect to an intermediate | middle vertical frame will become easy. Since the vertical outdoor side is supported by the sliding door, the reinforcing material tends to move to the indoor side when heated. Therefore, the locking member can restrict warping deformation of the reinforcing material simply by locking the reinforcing material on the outer peripheral surface of the screw. Since the forming operation and the screw hole positioning are not required, the installation operation is further facilitated.
本発明に係る建具において、前記補強材は、少なくとも前記方立の見込み方向に沿う第1板部と、該第1板部から屈曲して前記方立の見付け方向に沿う第2板部と、を有し、前記係止部材は、前記第2板部の室内側見付け面に対向配置された構成としてもよい。そうすると、補強材による方立の補強と、規制部材による補強材の移動規制とを容易に両立できる。 In the joinery according to the present invention, the reinforcing member includes at least a first plate portion along a prospective direction of the vertical, a second plate portion bent from the first plate portion and along the direction of finding the vertical, The locking member may be configured to be opposed to the indoor-side finding surface of the second plate portion. Then, it is possible to easily achieve both vertical reinforcement by the reinforcing material and restriction of movement of the reinforcing material by the restricting member.
本発明に係る建具において、前記中間縦枠は、前記袖壁パネルの側端部を保持する開口溝の室内側壁部が形成された室内側枠部と、前記開口溝の室外側壁部が形成された室外側枠部と、該室内側枠部と該室外側枠部との間を連結する断熱部材と、を有し、前記係止部材は、前記室外側枠部に取り付けられた構成としてもよい。そうすると、火災時に中間縦枠の断熱部材が溶融又は消失し、中間縦枠の室内側枠部と室外側枠部とが分離した場合であっても、規制部材が補強材の室内側見付け面に係止されるため、室外側枠部が室外側に移動することが規制される。このため、室外側枠部による袖壁パネルの保持状態が維持され、袖壁パネルの脱落が防止される。 In the joinery according to the present invention, the intermediate vertical frame is formed with an indoor side frame portion in which an indoor side wall portion of an opening groove that holds a side end portion of the sleeve wall panel is formed, and an outdoor side wall portion of the opening groove. An outdoor frame part, and a heat insulating member that connects the indoor frame part and the outdoor frame part, and the locking member is attached to the outdoor frame part. Good. Then, even if the heat insulating member of the intermediate vertical frame melts or disappears in the event of a fire and the indoor side frame portion and the outdoor side frame portion of the intermediate vertical frame are separated, the regulating member is placed on the indoor side finding surface of the reinforcing material. Since it is locked, the outdoor frame portion is restricted from moving to the outdoor side. For this reason, the holding state of the sleeve wall panel by the outdoor frame is maintained, and the sleeve wall panel is prevented from falling off.
本発明に係る建具において、前記方立の前記内側見込み面と、該内側見込み面と対向する前記中間縦枠の外側見込み面との間には、樹脂製の形材が配設されており、加熱されると膨張する熱膨張性部材を、前記樹脂製の形材が配設された前記内側見込み面と前記外側見込み面との間の空間に臨むように設けた構成としてもよい。そうすると、火災時に膨張した熱膨張性部材により、樹脂製の形材が焼失した際に形成される方立と中間縦枠との間の隙間を塞ぎ、この隙間が室内外方向の貫通孔となることを防止する。 In the joinery according to the present invention, a resin profile is disposed between the inner prospective surface of the vertical and the outer prospective surface of the intermediate vertical frame facing the inner prospective surface, It is good also as a structure which provided the thermal expansible member which expand | swells when heated so that it may face the space between the said inner surface and the said outer surface where the said resin-made shape material was arrange | positioned. Then, the thermally expandable member that expands in the event of a fire closes the gap between the vertical and intermediate vertical frame formed when the resin profile is burned out, and this gap becomes a through hole in the indoor / outdoor direction. To prevent that.
本発明によれば、建具の防火性能を向上することができる。 According to the present invention, the fire performance of joinery can be improved.

以上のように構成された建具10が火災で加熱された場合、袖壁パネル20の上端部付近では、断熱部材56が溶融又は消失し、袖壁パネル20の上端部を保持する上框18aの室内側框部54と室外側框部55とが分離する。しかしながら、建具10では、規制金具80によって室外側框部55が室外側に移動することが規制されている。このため、室外側框部55の脱落が防止され、室外側框部55による袖壁パネル20の上端部の保持状態が維持されるため、袖壁パネル20の脱落を防止でき、防火性能を向上することができる。規制金具80は、袖付引戸以外の建具にも利用可能であり、例えば建物躯体に固定された開口枠(框体)にパネル体を嵌め殺した嵌め殺し窓等にも利用できる。 When the joinery 10 configured as described above is heated by a fire, the heat insulating member 56 melts or disappears in the vicinity of the upper end portion of the sleeve wall panel 20, and the upper collar 18 a that holds the upper end portion of the sleeve wall panel 20 The indoor side flange 54 and the outdoor side flange 55 are separated. However, in the joinery 10, the movement of the outdoor flange portion 55 to the outdoor side is restricted by the restriction fitting 80. For this reason, the outdoor side collar part 55 is prevented from falling off, and the holding state of the upper end part of the sleeve wall panel 20 by the outdoor side collar part 55 is maintained, so that the sleeve wall panel 20 can be prevented from falling off and the fire prevention performance is improved. can do. The restricting metal fitting 80 can be used for fittings other than sliding doors with sleeves. For example, the restricting metal fitting 80 can be used for a fitting window in which a panel body is fitted in an opening frame (housing) fixed to a building frame.
建具10は、方立44に設けた補強材90の室内側への移動を規制する係止部材92を、上框18a、下框18b、及び戸尻側縦枠12dと強固に框組された中間縦枠46に取り付けている。このため、火災時に補強材90が熱伸びし、中央部が室内側に移動するような弓状の反り変形を生じることを係止部材92によって抑制できる。その結果、方立44と引戸16との間での室内外方向の貫通孔の形成を防止できる。従って、係止部材92は、補強材90の長手方向(上下方向)で少なくとも中央部又はその付近に設けられることが望ましい。本実施形態では係止部材92は、例えば上端付近、中央部、下端付近にそれぞれ設置している。なお、方立44の室外側には引戸16が設けられるため、補強材90が上記した方向と逆方向に弓状の反り変形をすることはほとんどないため、係止部材92は補強材90の室内側への移動を規制可能であればよい。係止部材92はねじ以外、例えば金属棒や金属片等で構成されてもよい。 In the joinery 10, the locking member 92 that restricts the movement of the reinforcing member 90 provided on the vertical wall 44 to the indoor side is firmly assembled with the upper eaves 18 a, the lower eaves 18 b, and the door bottom side vertical frame 12 d. It is attached to the intermediate vertical frame 46. For this reason, it can suppress by the latching member 92 that the reinforcing material 90 heat-extends at the time of a fire, and produces the bow-shaped curvature deformation | transformation which a center part moves indoor side. As a result, it is possible to prevent the formation of a through hole in the indoor / outdoor direction between the vertical 44 and the sliding door 16. Therefore, it is desirable that the locking member 92 is provided at least in the central portion or the vicinity thereof in the longitudinal direction (vertical direction) of the reinforcing member 90. In the present embodiment, the locking member 92 is installed, for example, near the upper end, near the center, and near the lower end. Since the sliding door 16 is provided on the outdoor side of the vertical wall 44, the reinforcing member 90 hardly deforms in a bow shape in the direction opposite to the above-described direction. What is necessary is just to be able to regulate the movement to the indoor side. The locking member 92 may be composed of, for example, a metal rod or a metal piece other than a screw.
また、本実施形態の場合、係止部材92は、中間縦枠46の室外側枠部49に固定されている。このため、火災時に中間縦枠46の断熱部材50が溶融又は消失し、中間縦枠46の室内側枠部48と室外側枠部49とが分離した場合であっても、係止部材92が補強材90の室内側見付け面90dに係止されるため、室外側枠部49が室外側に移動することが規制される。このため、室外側枠部49の脱落が防止され、室外側枠部49による袖壁パネル20の側端部の保持状態が維持され、袖壁パネル20の脱落が一層確実に防止される。 In the case of this embodiment, the locking member 92 is fixed to the outdoor side frame portion 49 of the intermediate vertical frame 46. Therefore, even when the heat insulating member 50 of the intermediate vertical frame 46 melts or disappears during a fire, and the indoor side frame portion 48 and the outdoor side frame portion 49 of the intermediate vertical frame 46 are separated, the locking member 92 is Since the reinforcing member 90 is locked to the indoor-side finding surface 90d, the outdoor frame portion 49 is restricted from moving to the outdoor side. Therefore, the outdoor side frame portion 49 is prevented from falling off, the holding state of the side end portion of the sleeve wall panel 20 by the outdoor side frame portion 49 is maintained, and the sleeve wall panel 20 is more reliably prevented from falling off.
建具10は、袖壁パネル20を保持する框体18の上框18a、中間縦枠46、及び戸尻側縦枠12dの開口溝52,66,68にそれぞれ脱落防止金具84,95,96を設けている。このため、建具10は、例えば火災時に長時間加熱され、上框18a、中間縦枠46、及び戸尻側縦枠12dの室外側框部55、室外側枠部49,39が軟化或いは溶融した場合、又は断熱部材56,50,40が溶融又は消失した場合であっても、袖壁パネル20の上端部及び側端部を保持しておくことができ、袖壁パネル20の脱落を一層確実に防止できる。この際、脱落防止金具84のブリッジ部84dは、断熱部材56から離間した位置で断熱部材56を跨ぐように延在し、固定部84aと保持部84cとの間を繋いでいる。このため、通常時、脱落防止金具84が室内側框部54と室外側框部55との間で熱橋となって建具10の断熱性能を低下させることが抑制されており、脱落防止金具95,96についても同様な断熱構造を有する。なお、上框18aは、袖壁パネル20の脱落防止のために重要な部位であるため、脱落防止金具84は袖壁パネル20の室内側表面20cを保持する保持部84bも有する構成となっている。但し、本実施形態の場合、保持部84b及びその室内側の室内側框部54の室内側には、建物躯体21やこれと固定された額縁部材が配設されているため、保持部84bを省略しても十分な防火性能を担保できる。また、上框18aに脱落防止金具84を設けていれば、他の脱落防止金具95,96を省略してもよく、反対に脱落防止金具95,96のみを設けて脱落防止金具84を省略してもよい。脱落防止金具84,95,96は、袖付引戸以外の建具にも利用可能であり、例えば建物躯体に固定された開口枠(框体)にパネル体を嵌め殺した嵌め殺し窓等や開口枠に開閉可能に支持される障子の框体にも利用できる。 The joinery 10 is provided with drop-off prevention fittings 84, 95, and 96 in the opening grooves 52, 66, and 68 of the upper collar 18a, the intermediate vertical frame 46, and the door-side vertical frame 12d that hold the sleeve wall panel 20, respectively. Provided. For this reason, the joinery 10 is heated for a long time, for example, in the event of a fire, and the upper flange 18a, the intermediate vertical frame 46, and the outdoor flange 55 and the outdoor frame 49, 39 of the door-side vertical frame 12d are softened or melted. In this case, the upper end portion and the side end portion of the sleeve wall panel 20 can be held even when the heat insulating members 56, 50, 40 are melted or disappeared, and the sleeve wall panel 20 can be more reliably detached. Can be prevented. At this time, the bridge portion 84d of the drop-off prevention metal fitting 84 extends so as to straddle the heat insulating member 56 at a position separated from the heat insulating member 56, and connects the fixing portion 84a and the holding portion 84c. For this reason, it is suppressed that the drop-off prevention metal fitting 84 normally becomes a thermal bridge between the indoor side flange portion 54 and the outdoor side flange portion 55 and deteriorates the heat insulation performance of the joinery 10. 96 have a similar heat insulating structure. Since the upper collar 18a is an important part for preventing the sleeve wall panel 20 from falling off, the stopper metal fitting 84 also has a holding portion 84b for holding the indoor side surface 20c of the sleeve wall panel 20. Yes. However, in the case of the present embodiment, since the building housing 21 and the frame member fixed thereto are arranged on the indoor side of the holding portion 84b and the indoor side flange portion 54 on the indoor side, the holding portion 84b is provided. Even if omitted, sufficient fireproof performance can be secured. Further, if the upper collar 18a is provided with the drop-off prevention metal fitting 84, the other drop-off prevention metal fittings 95, 96 may be omitted, and conversely, only the drop-off prevention metal fitting 95, 96 is provided and the drop-off prevention metal fitting 84 is omitted. May be. The drop-off prevention metal fittings 84, 95, and 96 can be used for fittings other than the sliding doors with sleeves. It can also be used for a shoji frame that can be opened and closed.
建具10において、脱落防止金具84,95,96は、耐火ガラスであるガラス板20bの各端面20e,20g,20hと対向する位置にそれぞれ熱膨張性部材86を有する。このため、火災時に熱膨張性部材86が膨張することにより、各脱落防止金具84,95,96とガラス板20bの各端面20e,20g,20hとの隙間が塞がれ、この隙間が室内外方向の貫通孔となることを防止できる。なお、本実施形態の場合は、下框18bの開口溝58に設けた補強材76にもガラス板20bの下端面20fと対向する位置に熱膨張性部材88を設けている。このため、建具10は、火災時にガラス板20bの外周端面と框体18との間の隙間が四周に亘って熱膨張性部材86,88によって塞がれるため、一層高い防火性能が得られる。 In the joinery 10, the drop-off prevention fittings 84, 95, and 96 have thermal expansion members 86 at positions facing the end faces 20 e, 20 g, and 20 h of the glass plate 20 b that is fireproof glass. For this reason, when the thermally expandable member 86 expands in the event of a fire, the gaps between the drop-off prevention metal fittings 84, 95, 96 and the end surfaces 20e, 20g, 20h of the glass plate 20b are closed, and the gaps are indoors and outdoors. It can prevent becoming a through hole in the direction. In the present embodiment, the reinforcing member 76 provided in the opening groove 58 of the lower rod 18b is also provided with a thermally expandable member 88 at a position facing the lower end surface 20f of the glass plate 20b. For this reason, since the clearance gap between the outer peripheral end surface of the glass plate 20b and the housing 18 is block | covered with the thermally expansible members 86 and 88 over four circumferences at the time of fire, the joiner 10 can obtain still higher fire prevention performance.
さらに脱落防止金具84,95,96は、ガラス板20bの室外側表面20dと対向する位置に熱膨張性部材87を有する。これにより、建具10の火災時には袖壁パネル20の室外側表面20dと脱落防止金具84,95,96との間の隙間が膨張した熱膨張性部材87で塞がれる。このため、この隙間が室内外方向に連通する貫通孔となることが防止されると共に、膨張した熱膨張性部材87によって袖壁パネル20が保持され、その脱落が一層確実に防止される。 Further, the drop-off prevention fittings 84, 95, 96 have a thermally expandable member 87 at a position facing the outdoor side surface 20d of the glass plate 20b. Thereby, at the time of the fire of the joinery 10, the gap between the outdoor surface 20 d of the sleeve wall panel 20 and the drop-off preventing metal fittings 84, 95, 96 is closed by the expanded thermal expansion member 87. For this reason, the gap is prevented from being a through hole communicating in the indoor / outdoor direction, and the sleeve wall panel 20 is held by the expanded thermal expansible member 87, and the fall off is more reliably prevented.
本実施形態の場合、袖壁パネル20の室外側のガラス板20bを耐火ガラスとしているため、このガラス板20bの周囲に熱膨張性部材86,87を設けた構成を例示したが、室内側のガラス板20aを耐火ガラスとした場合はこちら側に熱膨張性部材86,87を設けるとよい。脱落防止金具84,95,96についても同様であり、室内側のガラス板20aを耐火ガラスとした場合は、室外側框部55、室外側枠部49,39に固定部84aを固定し、ブリッジ部84dを室内側框部54、室内側枠部48,38側へと延在させ、保持部84cを室内側表面20cに対向配置するとよい。 In the case of this embodiment, since the glass plate 20b on the outdoor side of the sleeve wall panel 20 is made of fireproof glass, the configuration in which the thermally expandable members 86 and 87 are provided around the glass plate 20b is exemplified. When the glass plate 20a is made of refractory glass, the thermally expandable members 86 and 87 are preferably provided on this side. The same applies to the drop-off prevention metal fittings 84, 95, and 96. When the indoor side glass plate 20a is made of fireproof glass, the fixing portion 84a is fixed to the outdoor side flange portion 55 and the outdoor side frame portions 49 and 39, and the bridge. The portion 84d may be extended to the indoor side flange portion 54 and the indoor side frame portions 48 and 38, and the holding portion 84c may be disposed to face the indoor side surface 20c.
建具10では、方立部14にも熱膨張性部材93,94を設けている。熱膨張性部材93は、当該建具10の火災時にPVC等の樹脂製のブリッジ材47が焼失した際に形成される方立44と中間縦枠46との間の隙間を塞ぎ、この隙間が室内外方向の貫通孔となることを防止する。また、熱膨張性部材94は、当該建具10の火災時に室内側煙返し片44bと引戸16の室外側煙返し片16hとの間の隙間を塞ぎ、この隙間が室内外方向の貫通孔となることを防止する。 In the joinery 10, the heat-expandable members 93 and 94 are also provided in the vertical portion 14. The heat-expandable member 93 closes the gap between the vertical wall 44 and the intermediate vertical frame 46 formed when the bridge member 47 made of resin such as PVC is burned out in the event of the fire of the joinery 10, and this gap is indoors. Prevents the formation of an outward through hole. Further, the thermally expandable member 94 closes a gap between the indoor smoke return piece 44b and the outdoor smoke return piece 16h of the sliding door 16 in the event of a fire of the joinery 10, and this gap becomes a through hole in the indoor / outdoor direction.
