Description

本発明は、躯体開口部に配置される防火建具に関する。 The present invention relates to a fire protection fitting arranged at a skeleton opening.

建物の躯体開口部に配置される建具には、耐火性能が求められている。
そして、近年、アルミの押出形材からなる枠体もしくは障子の框体を四周に組んでなる枠部材の内周にパネル体を配置してなる建具において、枠体もしくは框体のパネル間口溝に加熱により膨張する加熱膨張材を配置して耐火性能を向上させた建具が公知となっている。（特許文献１） Fire resistance is required for fittings placed in the opening of the building frame.
In recent years, in fittings in which a frame body made of extruded aluminum or a frame body of a shoji is assembled on four circumferences and a panel body is arranged on the inner circumference of the frame member, the panel frontage groove of the frame body or the frame body is used. Joinery with improved fire resistance by arranging a heat-expanding material that expands by heating is known. (Patent Document 1)

特開２０１６－１８０２６９公報JP-A-2016-180269

前記特許文献１の建具は、枠体もしくは框体のパネル間口溝に加熱により膨張する加熱膨張材を配置することで耐火性能を向上させることはできるが、パネル間口溝内に配置された加熱膨張材がはがれることがあった。そのため加熱膨張材を保持するためのホルダーを形成することも考えられるが、パネル間口内にホルダーを構成する左右の係止片がパネル間口の内面から突出するために、横材と竪材との結合のために切除等の加工が必要となり、また、パネル間口内に侵入した水の排水の妨げとなる懸念があった。 The fitting of Patent Document 1 can improve the fire resistance performance by arranging a heat-expanding material that expands by heating in the panel frontage groove of the frame or frame, but the heat expansion is arranged in the panel frontage groove. The material sometimes came off. Therefore, it is conceivable to form a holder for holding the heat-expanding material, but since the left and right locking pieces constituting the holder protrude from the inner surface of the panel frontage in the panel frontage, the cross member and the vertical member are used. There was a concern that processing such as excision would be required for bonding, and that it would hinder the drainage of water that had entered the frontage of the panel.

本発明は、上記の事情を鑑みたものであり、防火建具において、施工性や排水性を低下させることなく、横材もしくは竪材に対して、加熱膨張材を安定して保持することを目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to stably hold a heat-expanding material with respect to a horizontal member or a vertical member without deteriorating workability and drainage in a fire protection fitting. And.

本発明の一実施形態は、パネル間口を有する上、下横材及び左、右竪材の内周にパネル体を備えてなり、横材及び竪材のパネル間口には、補強部材が配置されていないとともに、加熱膨張材を収容するホルダーが、見込み方向の一方に寄せられて、パネル間口の見込壁部から突出しないように見込壁部に飲み込ませて設けられており、ホルダーの一方の係止部がパネル間口の一方の見付壁部に設けられている防火建具である。 In one embodiment of the present invention, a panel body is provided on the inner circumferences of the upper and lower horizontal members and the left and right vertical members having a panel frontage, and reinforcing members are arranged on the panel frontages of the horizontal members and the vertical members. In addition, the holder for accommodating the heat expansion material is provided so as to be moved to one side in the prospective direction and swallowed into the prospective wall portion so as not to protrude from the prospective wall portion of the panel frontage, and one of the holders is engaged. This is a fire protection fitting whose stop is provided on one of the found walls of the panel frontage .

本発明により、施工性や排水性を低下させることなく、加熱膨張材を安定して保持することができる。 According to the present invention, the heat expansion material can be stably held without deteriorating workability and drainage.

Therefore, it is not necessary to cut the holder 234 when the end surface of the upper stile 21 (or the lower stile 22) is brought into contact with the bottom wall portion 231a of the panel frontage 232 of the right stile 23 and the right stile is joined. The indoor side surface of the holder 234 formed on the outdoor wall portion 232b of the stile 23 can be brought into contact with the outdoor surface of the upper stile 21 (or the lower stile 22) and joined by wax.

そして、具体的には、図５（ａ）に示すように、上框２１のホルダー２１４は、上框２１の室内側壁部（見付壁部）２１２ａの室外側面（見付面）に形成されており、加熱膨張材ｆ１を収容する収容部２１４ａと収容部２１４ａの上側に設けられる上係止部２１４ｂと収容部２１４ａの下側に設けられる下係止部２１４ｃを有しており、上、下係止部２１４ｂ，２１４ｃの間が加熱時に加熱膨張材ｆ１が膨出する開口部となっている。 Specifically, as shown in FIG. 5A, the holder 214 of the upper stile 21 is formed on the outdoor side surface (finding surface) of the indoor side wall portion (finding wall portion) 212a of the upper stile 21. It has an accommodating portion 214a for accommodating the heat expansion material f1, an upper locking portion 214b provided on the upper side of the accommodating portion 214a, and a lower locking portion 214c provided on the lower side of the accommodating portion 214a. The space between the lower locking portions 214b and 214c is an opening in which the heating expansion material f1 swells during heating.

上框２１のホルダー２１４の上係止部２１４ｂが上框本体２１１の中空部内に飲み込まれて底壁部２１１ａに溝状に形成されており、上係止部２１４ｂが上框２１の底壁部２１１ａの下面から下方に突出することなく、底壁部２１１ａの下面はほぼ面一状態となっている。 The upper locking portion 214b of the holder 214 of the upper stile 21 is swallowed into the hollow portion of the upper stile main body 211 and is formed in a groove shape on the bottom wall portion 211a, and the upper locking portion 214b is the bottom wall portion of the upper stile 21. The lower surface of the bottom wall portion 211a is substantially flush with each other without protruding downward from the lower surface of the 211a.

また、図５（ｂ）に示すように、下框２２のホルダー２２４は、下框２２の室外側壁部（見付壁部）２２２ｂの室内側面（見付面）に形成されており、加熱膨張材ｆ２を収容する収容部２２４ａと収容部２２４ａの上側に設けられる上係止部２２４ｂと収容部２２４ａの下側に設けられる下係止部２２４ｃを有しており、上、下係止部２２４ｂ，２２４ｃの間が加熱時に加熱膨張材ｆ２が膨出する開口部となっている。 Further, as shown in FIG. 5B, the holder 224 of the lower stile 22 is formed on the indoor side surface (finding surface) of the outdoor side wall portion (finding wall portion) 222b of the lower stile 22 and is heated and expanded. It has an accommodating portion 224a for accommodating the material f2, an upper locking portion 224b provided on the upper side of the accommodating portion 224a, and a lower locking portion 224c provided on the lower side of the accommodating portion 224a. Between 224c and 224c is an opening in which the heating expansion material f2 swells during heating.

そして、下框２２のホルダー２２４の下係止部２２４ｃが下框本体２２１の中空部内に飲み込まれて底壁部２２１ａに溝状に形成されており、下係止部２２４ｃが下框２２の底壁部２２１ａの上面から上方に突出することなく、底壁部２１１ａの上面はほぼ面一状態となっている。 Then, the lower locking portion 224c of the holder 224 of the lower stile 22 is swallowed into the hollow portion of the lower stile main body 221 and is formed in a groove shape on the bottom wall portion 221a, and the lower locking portion 224c is the bottom of the lower stile 22. The upper surface of the bottom wall portion 211a is substantially flush with each other without protruding upward from the upper surface of the wall portion 221a.

また、図５（ｃ）に示すように、右竪框２３のホルダー２３４は、右竪框２３の室外側壁部（見付壁部）２３２ｂの室内側面（見付面）に形成されており、加熱膨張材ｆ３を収容する収容部２３４ａと収容部２３４ａの外周側に設けられる外係止部２３４ｂと収容部２３４ａの内周側に設けられる内係止部２３４ｃを有しており、内、外係止部２３４ｂ，２３４ｃの間が加熱時に加熱膨張材ｆ３が膨出する開口部となっている。 Further, as shown in FIG. 5C, the holder 234 of the right stile 23 is formed on the indoor side surface (spot surface) of the outdoor wall portion (spot wall portion) 232b of the right stile 23. It has an accommodating portion 234a for accommodating the heat expansion material f3, an outer locking portion 234b provided on the outer peripheral side of the accommodating portion 234a, and an inner locking portion 234c provided on the inner peripheral side of the accommodating portion 234a. The space between the locking portions 234b and 234c is an opening in which the heating expansion material f3 swells during heating.

そして、右竪框２３のホルダー２３４の外係止部２３４ｂが右竪框本体２３１の中空部内に飲み込まれて底壁部２３１ａに溝状に形成されており、底壁部２３１ａの内周面から内周に突出することなく、底壁部２３１ａの内周面はほぼ面一状態となっている。
なお、左竪框２４のパネル間口２４２内に形成されたホルダー２４４は、右竪框２３のそれと同様であるので、説明を省略する。 Then, the outer locking portion 234b of the holder 234 of the right stile 23 is swallowed into the hollow portion of the right stile main body 231 and is formed in a groove shape on the bottom wall portion 231a from the inner peripheral surface of the bottom wall portion 231a. The inner peripheral surface of the bottom wall portion 231a is almost flush with each other without protruding to the inner circumference.
Since the holder 244 formed in the panel frontage 242 of the left stile 24 is the same as that of the right stile 23, the description thereof will be omitted.

以上のように、上記各実施形態の建具においては、障子の框材のパネル間口に形成されるホルダーが、その一部もしくは全部を框材の中空部内に埋設するように設けられている。 As described above, in the fittings of each of the above-described embodiments, the holder formed at the panel frontage of the stile material of the shoji is provided so as to bury a part or all of the holder in the hollow portion of the stile material.

第１の実施形態の建具は、以下の効果を奏することができる。
パネル間口の底壁部にホルダー（膨張材保持部）の全部が框本体部の中空部内に埋設するように設けることによって、ホルダー（膨張材保持部）の係止部がパネル間口内に突出することがなく、框材を四周に組むときにホルダー（膨張材保持部）が邪魔にならずに、ホルダー（膨張材保持部）の係止部を削る等の加工をする必要がない。また、地震時等にパネルが衝突してパネルが破損等傷つくことを低減することができる。 The fitting of the first embodiment can exert the following effects.
By providing the bottom wall of the panel frontage so that the entire holder (expansion material holding portion) is embedded in the hollow portion of the stile body, the locking portion of the holder (expansion material holding portion) protrudes into the panel frontage. There is no need to cut the locking part of the holder (expansion material holding part) so that the holder (expansion material holding part) does not get in the way when assembling the stile material around four circumferences. In addition, it is possible to reduce damage such as damage to the panel due to collision of the panel in the event of an earthquake or the like.

そして、各框材に設ける加熱膨張材をパネル間口の見込壁に設けることで、パネル体を強固に保持することができ、特に、下框と竪框に設ける加熱膨張材をパネル体（複層パネル）の室外側に配置した耐火パネルの小口に対向するように配置しているので下方からの火炎に対して素早く膨張して、室外側の耐火性パネルを強固に保持することができる。 Then, by providing the heat-expanding material provided for each frame material on the prospective wall of the panel frontage, the panel body can be firmly held, and in particular, the heat-expanding material provided for the lower frame and the vertical frame is provided for the panel body (multi-layer). Since it is arranged so as to face the edge of the refractory panel arranged on the outdoor side of the panel), it can be quickly expanded against a flame from below, and the refractory panel on the outdoor side can be firmly held.

そして、火災の進行により室外側の耐火パネルが変形し、さらには脱落することがあっても、上框２１のパネル間口２１２内に配置される加熱膨張材ｆ１が室内側のパネル２５２に向かって膨張しており、室内側のパネル２５２を保持するので、室外側の耐火パネル２５１と室内側のパネル２５２とを同時に失うことを防ぐことができる。 Then, even if the refractory panel on the outdoor side is deformed due to the progress of the fire and may fall off, the heat expansion material f1 arranged in the panel frontage 212 of the upper stile 21 is directed toward the panel 252 on the indoor side. Since it is inflated and holds the panel 252 on the indoor side, it is possible to prevent the fireproof panel 251 on the outdoor side and the panel 252 on the indoor side from being lost at the same time.

また、上框２１のパネル間口２１２に配置する加熱膨張材ｆ１を室内側に配置することで、火災時に内外ガラス間で発生して上昇する、比重の小さい可燃ガスを室外側に排出して室内側に侵入することを抑制することができる。
そして、上、下框２１，２２および右，左竪框２３，２４の各パネル間口内に長尺の補強部材が四周にわたって配置されていないので、建具の重量を抑えることができるとともに、製造工程の増加や価格の増加を抑制することができる。 Further, by arranging the heat expansion material f1 arranged at the panel frontage 212 of the upper stile 21 on the indoor side, combustible gas having a small specific density generated between the inner and outer glasses in the event of a fire and rising is discharged to the outdoor side to be discharged to the outdoor side. It is possible to suppress the invasion to the inside.
Further, since long reinforcing members are not arranged over four circumferences in the frontages of the upper and lower stiles 21 and 22 and the right and left stiles 23 and 24, the weight of the fittings can be suppressed and the manufacturing process can be performed. It is possible to suppress the increase in the price and the increase in the price.

第２の実施形態の建具は、以下の効果を奏することができる。
框本体部の中空部内にホルダーの外周側の係合部を埋設するように設けることによって、框材を四周に組むときには、内周側の係止部を削り取ればよく、加工が容易となる。 The fitting of the second embodiment can exert the following effects.
By burying the engaging portion on the outer peripheral side of the holder in the hollow portion of the stile body, when assembling the stile material in four circumferences, the locking portion on the inner peripheral side may be scraped off, which facilitates processing. ..

特に、図５（ａ）に示すように、下框２２の側壁部にホルダー（膨張材保持部）を設けた例においては、下框２２の底壁部２２１ａから突出する部位もなく、また、加熱膨張材ｆが底壁部２２１ａに存在しないので、パネル間口に浸入した結露水等の排水穴２２１ｂ等からの排水を妨げることがない。 In particular, as shown in FIG. 5A, in the example in which the holder (expansion material holding portion) is provided on the side wall portion of the lower stile 22, there is no portion protruding from the bottom wall portion 221a of the lower stile 22, and there is no portion. Since the heat expansion material f does not exist in the bottom wall portion 221a, it does not interfere with the drainage of the condensed water or the like that has entered the frontage of the panel from the drainage hole 221b or the like.

なお、本発明は、上記各実施形態の構成に限定されるものではない。
例えば、第２の実施形態の建具におけるホルダーを設ける見付壁部は、室内側壁部と室外側壁部のいずれの壁部でもよく、各框材において、同一側にホルダーを設けても良いし、設ける框によって異ならせてもよい。
また、框材の一部については、第１の実施形態の建具に見られるような、パネル間口の見込壁部にホルダーを設けるものであってもよい。
また、上記各実施形態の建具においては、複層パネルの室外側に耐火パネルを配置しているが、室内側に耐火パネルを配置した複層パネルを用いてもよい。
また、３枚以上の複層パネルを用いる場合は、見込み方向で室外側端部のみなど、一方側端部のみのパネル一枚のみを高価な耐火パネルとし、残り全てのパネルを比較的安価な非耐火パネルとすることにより、低価格で効果を発揮できて好ましい。 The present invention is not limited to the configuration of each of the above embodiments.
For example, the found wall portion in which the holder is provided in the fitting of the second embodiment may be any wall portion of the indoor side wall portion and the outdoor side wall portion, and the holder may be provided on the same side in each frame material. It may be different depending on the stile provided.
Further, for a part of the stile material, a holder may be provided on the prospective wall portion of the panel frontage as seen in the fittings of the first embodiment.
Further, in the fittings of each of the above embodiments, the fireproof panel is arranged on the outdoor side of the multi-layer panel, but the multi-layer panel on which the fireproof panel is arranged on the indoor side may be used.
When using three or more multi-layer panels, only one panel with only one side end, such as only the outdoor end, is used as an expensive fireproof panel in the prospective direction, and all the remaining panels are relatively inexpensive. It is preferable to use a non-fireproof panel because it can be effective at a low price.

なお、上記各実施形態の建具においては、上、下框及び右、左竪框の全てパネル間口において長尺の補強部材を配置することなく、加熱膨張材によって防火性能を維持することができるものではあるが、いずれかの框に例えば多少の補強機能を有する短尺の補助部材等が配置されていてもよい。
また、複層パネルを保持する部材は、グレイジングチャンネルに限るものではなく、パネルの内外をそれぞれ室外ビードと室内ビードで挟持してもよく、または硬化性のコーキングやホットメルトなどの接着剤で接着しながら、パネルを内外で挟持してもよい。若しくはパネルの内外一方をビードで、他方に接着剤を配置してパネルを挟持してもよい。
さらに、横材および竪材を有する建具は、どのような種類の建具であってもよく、また横材および竪材は框材に限るものではなく、ＦＩＸ窓の枠材であってもよい。 In the fittings of each of the above embodiments, the fire prevention performance can be maintained by the heat expansion material without arranging long reinforcing members at the panel frontages of the upper, lower stile, right and left stiles. However, for example, a short auxiliary member having some reinforcing function may be arranged in any of the stiles.
Further, the member that holds the multi-layer panel is not limited to the glazing channel, and the inside and outside of the panel may be sandwiched between the outdoor bead and the indoor bead, respectively, or with an adhesive such as curable caulking or hot melt. The panel may be sandwiched inside and outside while adhering. Alternatively, one of the inside and outside of the panel may be a bead, and an adhesive may be placed on the other to sandwich the panel.
Further, the fitting having the horizontal member and the vertical member may be any kind of fitting, and the horizontal member and the vertical member are not limited to the stile material, and may be a frame member of a FIX window.
