Description

本発明は、シャッター用ガイドレールの防火構造に関する。   The present invention relates to a fire prevention structure for a guide rail for a shutter.

シャッターカーテンの両側縁をガイドするガイドレールは、アルミ合金などによる押出成形品が用いられることが多い。アルミ合金よりなることで、ガイドレールは意匠性を持たせることができ、またその素材により防錆性もあり住宅用には好適である。ところが、アルミ合金などによるガイドレールは、火災発生時に過度の熱を受けると変形を起こし、さらには溶ける可能性があり、シャッター装置の本来の機能を十分に発揮できない虞がある。そこで、防火機能の向上を図ることができる閉鎖体のガイドレールの構造が提案されている(例えば特許文献1参照)。   As the guide rail for guiding both side edges of the shutter curtain, an extruded product made of an aluminum alloy or the like is often used. By being made of an aluminum alloy, the guide rail can have design properties, and its material has rust prevention properties, which is suitable for housing. However, a guide rail made of aluminum alloy or the like may be deformed when it receives excessive heat in the event of a fire, and may further melt, so that the original function of the shutter device may not be fully exhibited. Therefore, a structure of a closed guide rail that can improve the fire prevention function has been proposed (see, for example, Patent Document 1).

この閉鎖体のガイドレールの構造は、空間を仕切る閉鎖体の端縁部分を挿入部に挿入してこの閉鎖体の移動を案内する閉鎖体のガイドレールの構造において、挿入部を形成するガイドレール本体と、このガイドレール本体を補強する補強材とを備える。補強材は、ガイドレール本体の長手方向の全長に渡って連続的に設けられていてもよく、あるいは断続的に設けられていてもよい。   The structure of the guide rail of the closing body includes a guide rail that forms the insertion portion in the structure of the guide rail of the closing body that guides the movement of the closing body by inserting an end edge portion of the closing body that partitions the space into the insertion portion. A main body and a reinforcing material for reinforcing the guide rail main body are provided. The reinforcing material may be provided continuously over the entire length in the longitudinal direction of the guide rail body, or may be provided intermittently.

この閉鎖体のガイドレールの構造によれば、補強材を設けてガイドレール本体を補強するので、ガイドレールの強度が全体として向上する。このため、防火や防煙などの防災上の機能や防犯上の機能の向上を図ることが可能となる。ガイドレールが火災発生時に過度の熱を受けて溶けてしまい、本来の機能を十分に発揮できなくなるという不都合を未然に防止することが可能となる。   According to the structure of the guide rail of the closed body, the reinforcing material is provided to reinforce the guide rail body, so that the strength of the guide rail is improved as a whole. For this reason, it is possible to improve disaster prevention functions such as fire prevention and smoke prevention and crime prevention functions. It is possible to prevent the inconvenience that the guide rail is melted by receiving excessive heat at the time of the occurrence of a fire and cannot fully perform its original function.

しかしながら、上記従来の防火タイプのシャッター装置は、ガイドレールなどの部材そのものを防火専用品にしたり、ガイドレール内部に補強部材を組み込んだりしている。このため、専用部品が増加し、生産効率を低下させた。また、既設のシャッター装置の防火性能を向上させたい場合においても、従来部品をこれらの防火専用部品に交換する必要があり、既設の部品を撤去するなど施工が煩雑となった。   However, in the above conventional fire-proof type shutter device, a member such as a guide rail itself is a dedicated fire-proof product, or a reinforcing member is incorporated inside the guide rail. For this reason, the number of dedicated parts increased and production efficiency decreased. In addition, when it is desired to improve the fire prevention performance of the existing shutter device, it is necessary to replace the conventional parts with these fire prevention dedicated parts, and the construction becomes complicated such as removing the existing parts.

本発明は上記状況に鑑みてなされたもので、その目的は、既設のシャッター装置の防火性能を容易に向上させることができるシャッター用ガイドレールの防火構造を提供することにある。   The present invention has been made in view of the above situation, and an object thereof is to provide a fire prevention structure of a shutter guide rail that can easily improve the fire prevention performance of an existing shutter device.

The first inner reinforcing member 41 and the first outer reinforcing member 39 sandwich at least one of a part of the first guide part 27 or a part of the first frame part 31 and a screw 43 which is a fixing means penetrating them. And fix.

第1ガイド部27と第1枠部31とは、アルミ押出成形材よりなる。第1ガイド部27は、カーテン部13の操出巻取方向に沿うカーテン縁部45のそれぞれをスリット47に抜け止め規制して案内する。抜け止め規制は、断面T字状の樹脂材よりなる抜け止め部材49をカーテン縁部45に取り付け、この抜け止め部材49をスリット47に係合して行われる。   The 1st guide part 27 and the 1st frame part 31 consist of aluminum extrusion molding materials. The first guide portion 27 guides each of the curtain edge portions 45 along the operation winding direction of the curtain portion 13 by preventing the curtain edge portions 45 from slipping out to the slits 47. The retaining prevention is performed by attaching a retaining member 49 made of a resin material having a T-shaped cross section to the curtain edge 45 and engaging the retaining member 49 with the slit 47.

第1ガイド部27は、第1枠部31と連結部分35にて連結される。連結部分35は、第1ガイド部27に形成される凹状爪51と、第1枠部31に形成されるL字状爪53と、からなる。連結部分35によって連結された第1ガイド部27と第1枠部31は、出隅部37が平断面形状がL字状の第1外側補強材39によって覆われる。出隅部37を覆った第1外側補強材39は、第1ガイド部27の延出片55を挟んで第1内側補強材41にビス43で固定される。つまり、延出片55は、第1外側補強材39と第1内側補強材41とに挟持される。なお、第1ガイド部27には開口側延出片57が形成され、開口側延出片57は第1枠部31の開口側起立片61に固定手段にて固定される。   The first guide portion 27 is connected to the first frame portion 31 by a connecting portion 35. The connecting portion 35 includes a concave claw 51 formed on the first guide portion 27 and an L-shaped claw 53 formed on the first frame portion 31. The first guide portion 27 and the first frame portion 31 connected by the connecting portion 35 are covered with a first outer reinforcing material 39 whose protruding corner portion 37 has an L-shaped flat cross section. The first outer reinforcing member 39 covering the protruding corner portion 37 is fixed to the first inner reinforcing member 41 with screws 43 with the extending piece 55 of the first guide portion 27 interposed therebetween. That is, the extending piece 55 is sandwiched between the first outer reinforcing member 39 and the first inner reinforcing member 41. The first guide portion 27 is formed with an opening-side extension piece 57, and the opening-side extension piece 57 is fixed to the opening-side standing piece 61 of the first frame portion 31 by fixing means.

第1内側補強材41は、他端が、第1枠部31の支持片63に固定手段であるリベット65によって固定される。第1枠部31は、基部が建物躯体29に固定される。つまり、第1ガイド部27を覆った第1外側補強材39と第1内側補強材41は、第1枠部31を介して建物躯体29に支持されている。第1枠部31には、第1外側補強材39または第1内側補強材41に覆われない部分が存在するが、その殆どは建物外装材67によって覆われ、外側からの延焼による直接的な影響は受けない。   The other end of the first inner reinforcing member 41 is fixed to the support piece 63 of the first frame portion 31 by a rivet 65 that is a fixing means. The base of the first frame portion 31 is fixed to the building frame 29. That is, the first outer reinforcing member 39 and the first inner reinforcing member 41 covering the first guide portion 27 are supported by the building frame 29 via the first frame portion 31. The first frame portion 31 includes a portion that is not covered by the first outer reinforcing member 39 or the first inner reinforcing member 41, but most of the portion is covered by the building exterior member 67, and is directly applied by fire spreading from the outside. Not affected.

また、第1ガイド部27と第1内側補強材41との間には空隙69が形成される。この空隙69は、断熱兼放熱層となる。空隙69を形成することで、第1ガイド部27からの熱を伝わりにくくし、かつ高温となった場合の第1ガイド部27の熱を放熱可能としている。   Further, a gap 69 is formed between the first guide portion 27 and the first inner reinforcing member 41. The gap 69 becomes a heat insulating and heat radiating layer. By forming the gap 69, heat from the first guide portion 27 is hardly transmitted, and heat of the first guide portion 27 when the temperature becomes high can be radiated.

第1外側補強材39の外側には化粧枠材である第1化粧枠材59が設けられ、第1化粧枠材59は第1外側補強材39を覆う。高温を遮断するために第1ガイド部27の外表面33を覆って設けられた第1外側補強材39が、さらにその外側に設けられた第1化粧枠材59によって覆われる。高温の阻止に特化された第1外側補強材39は、外観からは見えなくなる。このように、第1外側補強材39は、第1化粧枠材59で覆われるので、外部からは第1外側補強材39が見えなくなり、デザイン性を損ねることがない。   A first decorative frame material 59, which is a decorative frame material, is provided outside the first outer reinforcing material 39, and the first decorative frame material 59 covers the first outer reinforcing material 39. A first outer reinforcing member 39 provided so as to cover the outer surface 33 of the first guide portion 27 in order to block the high temperature is covered with a first decorative frame member 59 provided further outside. The first outer reinforcement 39 specialized for high temperature prevention is not visible from the exterior. Thus, since the 1st outer side reinforcement material 39 is covered with the 1st decorative frame material 59, the 1st outer side reinforcement material 39 becomes invisible from the outside, and design property is not impaired.

第1外側補強材39と、第1内側補強材41は鋼板よりなる。鋼板の板厚は0.8〜2mm程度が好適となる。あまり厚いと重量が増すためである。第1外側補強材39、第1内側補強材41は、第1ガイド部27に沿う方向が、全通しに連続であってもよいし、断続で複数で構成されてもよい。全通しのほうが、補強として、より効果的である。また、第1外側補強材39や第1内側補強材41は、第1ガイド部27の長手方向に複数に分割して製作すれば、製作、施工を容易にできる。第1外側補強材39は、帯状の鋼板を長手方向に沿う折り曲げ部71で折り曲げることで、出隅部37を覆うL字形に、安価かつ容易に製作可能となる。   The first outer reinforcing material 39 and the first inner reinforcing material 41 are made of steel plates. The plate thickness of the steel plate is preferably about 0.8 to 2 mm. This is because if it is too thick, the weight increases. The first outer reinforcing member 39 and the first inner reinforcing member 41 may be continuous in the direction along the first guide portion 27, or may be constituted by a plurality of intermittently. All-rounder is more effective as reinforcement. Moreover, if the 1st outer side reinforcement material 39 and the 1st inner side reinforcement material 41 are divided | segmented into several in the longitudinal direction of the 1st guide part 27, manufacture and construction can be made easy. The first outer reinforcing member 39 can be manufactured inexpensively and easily into an L-shape that covers the protruding corner portion 37 by bending a belt-shaped steel plate with a bending portion 71 along the longitudinal direction.

図4は外側補強材の掛かり代部73を説明する図2の要部拡大図である。
第1外側補強材39は、カーテン縁部45と重なる掛かり代部73を有する。アルミ合金製の第1ガイド部27は火災による熱で変形を起こし、さらには溶ける虞がある。また、抜け止め部材49は、樹脂製であり、耐風機能としては有効であるが、火災による熱で溶けて無くなってしまう虞がある。第1外側補強材39は、掛かり代部73が設けられていることで、カーテン縁部45の抜け止め部材49が溶けても、カーテン縁部45に重なる掛かり代部73を残すことができる。すなわち、左右のガイド部の間隔距離が、カーテン部13の幅長よりも短くなり、これにより、アルミ製の第1ガイド部27が熱で変形したり溶けたりしても、掛かり代部73がカーテン縁部に引っ掛かり、カーテン部13が第1ガイド部27から外れなくなる。このようにして、耐火材である第1外側補強材39の掛かり代部73で両側縁の掛かりを担保してカーテン部13の脱落を防ぐことができる。
FIG. 4 is an enlarged view of a main part of FIG. 2 for explaining the hook portion 73 of the outer reinforcing material.
The first outer reinforcing material 39 has a hook margin 73 that overlaps with the curtain edge 45. The first guide portion 27 made of aluminum alloy may be deformed by heat from a fire and may be melted. Further, the retaining member 49 is made of resin and is effective as a wind-resistant function, but may be lost due to melting by heat from a fire. Since the first outer reinforcing member 39 is provided with the hook margin 73, the hook margin 73 overlapping the curtain edge 45 can be left even if the retaining member 49 of the curtain edge 45 is melted. That is, the distance between the left and right guide portions is shorter than the width of the curtain portion 13, so that even when the first guide portion 27 made of aluminum is deformed or melted by heat, the hooking margin portion 73 is The curtain is caught on the edge of the curtain and the curtain 13 is not detached from the first guide 27. In this way, the hanging portion 73 of the first outer reinforcing material 39, which is a refractory material, can be secured at both side edges to prevent the curtain portion 13 from falling off.

次に、第1実施形態に係るシャッター用ガイドレール11Aの防火構造の作用を説明する。
第1実施形態の防火構造では、第1ガイド部27の外表面33が、第1ガイド部27と第1枠部31との連結部分35となる出隅部37を含んで第1外側補強材39によって覆われる。第1ガイド部27を覆った第1外側補強材39は、第1枠部31の内側に配置される第1内側補強材41と第1枠部31を挟んで固定手段にて固定される。つまり、第1ガイド部27は、外部からの延焼が第1外側補強材39によって阻止される。第1外側補強材39は、高温となっても、第1枠部31を挟んで第1内側補強材41に固定されているので、建物躯体29への支持を高温下で長時間、維持し続けることができる。

In addition, the 2nd guide part reinforcement material 131 can be removed from the 4th guide part 125 by removing the rivet 65, From this, it becomes possible to cancel | release the drop-off regulation with respect to the curtain part 13. FIG. That is, the second guide portion reinforcing member 131 is configured to be removable, and maintenance of the curtain portion 13 is possible. In order to make this maintainability easier, the fixing means 65 made of the rivet may be constituted by a screw, a bolt, a nut, or the like.

第2ガイド部補強材131と、第4内側補強材133と、第3支持補強材135と、は鋼板よりなる。第2ガイド部補強材131、第4内側補強材133、第3支持補強材135は、第4ガイド部125に沿う方向が、全通しに連続であってもよいし、断続で複数で構成されてもよい。全通しのほうが、補強として、より効果的である。また、第2ガイド部補強材131、第4内側補強材133、第3支持補強材135は、第4ガイド部125の長手方向に複数に分割して製作すれば、製作、施工を容易にできる。第4内側補強材133、第3支持補強材135は、帯状の鋼板を長手方向に沿う折り曲げ部71でZ字形、略W字状に折り曲げることで、安価かつ容易に製作可能となる。   The 2nd guide part reinforcement material 131, the 4th inner side reinforcement material 133, and the 3rd support reinforcement material 135 consist of steel plates. The second guide portion reinforcing material 131, the fourth inner reinforcing material 133, and the third support reinforcing material 135 may be continuous in the direction along the fourth guide portion 125, or may be constituted by a plurality of intermittent. May be. All-rounder is more effective as reinforcement. In addition, if the second guide part reinforcing material 131, the fourth inner reinforcing material 133, and the third supporting reinforcing material 135 are divided into a plurality of parts in the longitudinal direction of the fourth guide part 125, the manufacturing and construction can be facilitated. . The fourth inner reinforcing member 133 and the third supporting reinforcing member 135 can be manufactured inexpensively and easily by bending a belt-shaped steel plate into a Z-shape or a substantially W-shape at a bending portion 71 along the longitudinal direction.

なお、第4実施形態に係る防火構造においても、第2ガイド部補強材131は、カーテン縁部45と重なる掛かり代部73を有する。これにより、アルミ製の第4ガイド部125が熱で変形したり溶けたりしても、掛かり代部73がカーテン縁部に引っ掛かり、カーテン部13が第2ガイド部補強材131から外れなくなる。このようにして、耐火材である第2ガイド部補強材131の掛かり代部73で両側縁の掛かりを担保してカーテン部13の脱落を防ぐことができる。   Note that, also in the fire prevention structure according to the fourth embodiment, the second guide portion reinforcing member 131 has a hooking margin portion 73 that overlaps with the curtain edge portion 45. As a result, even if the fourth guide portion 125 made of aluminum is deformed or melts by heat, the hooking portion 73 is caught on the curtain edge portion, and the curtain portion 13 is not detached from the second guide portion reinforcing material 131. In this way, the hook portion 73 of the second guide portion reinforcing member 131, which is a refractory material, can be secured on both side edges to prevent the curtain portion 13 from falling off.

次に、第4実施形態に係るシャッター用ガイドレール11Dの防火構造の作用を説明する。
第4実施形態の防火構造では、第4ガイド部125の内方に第2ガイド部補強材131が設けられ、この第2ガイド部補強材131は、第4ガイド部125を挟んで第4内側補強材133に固定される。第4内側補強材133は、第4ガイド部125、第4枠部127、第3支持補強材135に固定される。第3支持補強材135は、第4枠部127とともに建物躯体29に固定される。つまり、第4ガイド部125は、内表面129を覆った第2ガイド部補強材131によって、高温による変形が生じにくくなる。この第2ガイド部補強材131は、第4内側補強材133を介して第3支持補強材135に固定され、さらに第3支持補強材135が第4枠部127とともに建物躯体29に固定される。なお、図11に示すように、第4ガイド部材125に第ガイド部補強材131を嵌合し、第4内側補強材133とともに、リベット65にてこれらを固定状態とした後に、予め建物躯体29側に固定されている第4枠部127及び第3支持補強材135に対して、取付爪145とフック部143とを係止し、ビス43にて固定する手順とする。
Next, the operation of the fire prevention structure of the shutter guide rail 11D according to the fourth embodiment will be described.
In the fire prevention structure of the fourth embodiment, the second guide part reinforcing material 131 is provided inside the fourth guide part 125, and the second guide part reinforcing material 131 is arranged on the fourth inner side across the fourth guide part 125. It is fixed to the reinforcing material 133. The fourth inner reinforcing material 133 is fixed to the fourth guide portion 125, the fourth frame portion 127, and the third support reinforcing material 135. The third support reinforcing material 135 is fixed to the building frame 29 together with the fourth frame portion 127. That is, the fourth guide portion 125 is less likely to be deformed by high temperature due to the second guide portion reinforcing material 131 covering the inner surface 129. The second guide portion reinforcing member 131 is fixed to the third supporting reinforcing member 135 via the fourth inner reinforcing member 133, and the third supporting reinforcing member 135 is fixed to the building frame 29 together with the fourth frame portion 127. . As shown in FIG. 11, after the fourth guide member 125 is fitted with the fourth guide portion reinforcing member 131 and fixed together with the fourth inner reinforcing member 133 with the rivets 65, the building housing 29 is previously provided. The attachment claw 145 and the hook portion 143 are locked to the fourth frame portion 127 and the third support reinforcing member 135 that are fixed to the side, and are fixed by screws 43.

第4実施形態に係るシャッター用ガイドレール11Dの防火構造によれば、第4ガイド部125を、第2ガイド部補強材131と第4内側補強材133とで挟んで固定手段65にて固定し、第4内側補強材133と第3支持補強材135とで第4ガイド部125の一部(垂直片137)と第4枠部127の一部とを挟み固定し、第3支持補強材135を第4枠部127とともに建物躯体29に固定するので、既設のシャッター装置17の防火性能を容易に向上させることができる。また、第2ガイド部補強材131の内側に補強材抜け止め片153を対向突出させたので、高温による変形が生じず、カーテン部13の脱落を起こし難くするとともに、この第2ガイド部補強材131が、係止先端縁部149と嵌合部151により第4ガイド部125に嵌合状態を保ち、加熱による変形を遅らせ、この第2ガイド部補強材131が第4ガイド部125の形状を維持させる。さらに、第4ガイド部125の内側を略コ字状の第2ガイド部補強材131で覆うことで、さらに剛性も向上することとなり、スラット25と第4ガイド部125との隙間にバールなどを差込みこじ開けるなどの不正な破壊的な行為に対して、第4ガイド部125の損壊を抑止でき、防犯性の向上にもなる。   According to the fire prevention structure of the shutter guide rail 11D according to the fourth embodiment, the fourth guide portion 125 is fixed by the fixing means 65 while being sandwiched between the second guide portion reinforcing material 131 and the fourth inner reinforcing material 133.

Is fixed to the building housing 29 together with the fourth frame portion 127, the fireproof performance of the existing shutter device 17 can be easily improved. In addition, since the reinforcing material retaining piece 153 is opposed to the inner side of the second guide portion reinforcing material 131, deformation due to high temperature does not occur, and the curtain portion 13 does not easily fall off, and the second guide portion reinforcing material 131 maintains the fitted state to the fourth guide part 125 by the locking tip edge part 149 and the fitting part 151 and delays deformation due to heating, and the second guide part reinforcing material 131 changes the shape of the fourth guide part 125. Let it be maintained. Further, by covering the inside of the fourth guide part 125 with the substantially U-shaped second guide part reinforcing material 131, the rigidity is further improved, and a bar or the like is provided in the gap between the slat 25 and the fourth guide part 125. It is possible to prevent the fourth guide portion 125 from being damaged by an illegal destructive action such as opening the plug, and the crime prevention performance is also improved.

本発明は、シャッター用ガイドレールの防火構造に関する。   The present invention relates to a fire prevention structure for a guide rail for a shutter.

シャッターカーテンの両側縁をガイドするガイドレールは、アルミ合金などによる押出成形品が用いられることが多い。アルミ合金よりなることで、ガイドレールは意匠性を持たせることができ、またその素材により防錆性もあり住宅用には好適である。ところが、アルミ合金などによるガイドレールは、火災発生時に過度の熱を受けると変形を起こし、さらには溶ける可能性があり、シャッター装置の本来の機能を十分に発揮できない虞がある。そこで、防火機能の向上を図ることができる閉鎖体のガイドレールの構造が提案されている(例えば特許文献1参照)。   As the guide rail for guiding both side edges of the shutter curtain, an extruded product made of an aluminum alloy or the like is often used. By being made of an aluminum alloy, the guide rail can have design properties, and its material has rust prevention properties, which is suitable for housing. However, a guide rail made of aluminum alloy or the like may be deformed when it receives excessive heat in the event of a fire, and may further melt, so that the original function of the shutter device may not be fully exhibited. Therefore, a structure of a closed guide rail that can improve the fire prevention function has been proposed (see, for example, Patent Document 1).

この閉鎖体のガイドレールの構造は、空間を仕切る閉鎖体の端縁部分を挿入部に挿入してこの閉鎖体の移動を案内する閉鎖体のガイドレールの構造において、挿入部を形成するガイドレール本体と、このガイドレール本体を補強する補強材とを備える。補強材は、ガイドレール本体の長手方向の全長に渡って連続的に設けられていてもよく、あるいは断続的に設けられていてもよい。   The structure of the guide rail of the closing body includes a guide rail that forms the insertion portion in the structure of the guide rail of the closing body that guides the movement of the closing body by inserting an end edge portion of the closing body that partitions the space into the insertion portion. A main body and a reinforcing material for reinforcing the guide rail main body are provided. The reinforcing material may be provided continuously over the entire length in the longitudinal direction of the guide rail body, or may be provided intermittently.

この閉鎖体のガイドレールの構造によれば、補強材を設けてガイドレール本体を補強するので、ガイドレールの強度が全体として向上する。このため、防火や防煙などの防災上の機能や防犯上の機能の向上を図ることが可能となる。ガイドレールが火災発生時に過度の熱を受けて溶けてしまい、本来の機能を十分に発揮できなくなるという不都合を未然に防止することが可能となる。   According to the structure of the guide rail of the closed body, the reinforcing material is provided to reinforce the guide rail body, so that the strength of the guide rail is improved as a whole. For this reason, it is possible to improve disaster prevention functions such as fire prevention and smoke prevention and crime prevention functions. It is possible to prevent the inconvenience that the guide rail is melted by receiving excessive heat at the time of the occurrence of a fire and cannot fully perform its original function.

しかしながら、上記従来の防火タイプのシャッター装置は、ガイドレールなどの部材そのものを防火専用品にしたり、ガイドレール内部に補強部材を組み込んだりしている。このため、専用部品が増加し、生産効率を低下させた。また、既設のシャッター装置の防火性能を向上させたい場合においても、従来部品をこれらの防火専用部品に交換する必要があり、既設の部品を撤去するなど施工が煩雑となった。さらに、特許文献1の構造では、火災時の加熱などにより外側のガイドレール本体が変形し内側の補強材から分離する恐れがあった。 However, in the above conventional fire-proof type shutter device, a member such as a guide rail itself is a dedicated fire-proof product, or a reinforcing member is incorporated inside the guide rail. For this reason, the number of dedicated parts increased and production efficiency decreased. In addition, when it is desired to improve the fire prevention performance of the existing shutter device, it is necessary to replace the conventional parts with these fire prevention dedicated parts, and the construction becomes complicated such as removing the existing parts. Furthermore, in the structure of Patent Document 1, the outer guide rail body may be deformed and separated from the inner reinforcing material due to heating during a fire or the like.

本発明は上記状況に鑑みてなされたもので、その目的は、既設のシャッター装置の防火性能を容易に向上させることができ、火災時の加熱などにより外側のガイドレール本体が内側の補強材から分離する恐れのない改良されたシャッター用ガイドレールの防火構造を提供することにある。 The present invention has been made in view of the above situation, and the purpose thereof is to easily improve the fire prevention performance of an existing shutter device, and the outer guide rail body from the inner reinforcing material by heating in the event of a fire or the like. An object of the present invention is to provide an improved fire prevention structure for a guide rail for a shutter which is not likely to separate .

And fix.

第1ガイド部27と第1枠部31とは、アルミ押出成形材よりなる。第1ガイド部27は、カーテン部13の操出巻取方向に沿うカーテン縁部45のそれぞれをスリット47に抜け止め規制して案内する。抜け止め規制は、断面T字状の樹脂材よりなる抜け止め部材49をカーテン縁部45に取り付け、この抜け止め部材49をスリット47に係合して行われる。   The 1st guide part 27 and the 1st frame part 31 consist of aluminum extrusion molding materials. The first guide portion 27 guides each of the curtain edge portions 45 along the operation winding direction of the curtain portion 13 by preventing the curtain edge portions 45 from slipping out to the slits 47. The retaining prevention is performed by attaching a retaining member 49 made of a resin material having a T-shaped cross section to the curtain edge 45 and engaging the retaining member 49 with the slit 47.

第1ガイド部27は、第1枠部31と連結部分35にて連結される。連結部分35は、第1ガイド部27に形成される凹状爪51と、第1枠部31に形成されるL字状爪53と、からなる。連結部分35によって連結された第1ガイド部27と第1枠部31は、出隅部37が平断面形状がL字状の第1外側補強材39によって覆われる。出隅部37を覆った第1外側補強材39は、第1ガイド部27の延出片55を挟んで第1内側補強材41にビス43で固定される。つまり、延出片55は、第1外側補強材39と第1内側補強材41とに挟持される。なお、第1ガイド部27には開口側延出片57が形成され、開口側延出片57は第1枠部31の開口側起立片61に固定手段にて固定される。   The first guide portion 27 is connected to the first frame portion 31 by a connecting portion 35. The connecting portion 35 includes a concave claw 51 formed on the first guide portion 27 and an L-shaped claw 53 formed on the first frame portion 31. The first guide portion 27 and the first frame portion 31 connected by the connecting portion 35 are covered with a first outer reinforcing material 39 whose protruding corner portion 37 has an L-shaped flat cross section. The first outer reinforcing member 39 covering the protruding corner portion 37 is fixed to the first inner reinforcing member 41 with screws 43 with the extending piece 55 of the first guide portion 27 interposed therebetween. That is, the extending piece 55 is sandwiched between the first outer reinforcing member 39 and the first inner reinforcing member 41. The first guide portion 27 is formed with an opening-side extension piece 57, and the opening-side extension piece 57 is fixed to the opening-side standing piece 61 of the first frame portion 31 by fixing means.

第1内側補強材41は、他端が、第1枠部31の支持片63に固定手段であるリベット65によって固定される。第1枠部31は、基部が建物躯体29に固定される。つまり、第1ガイド部27を覆った第1外側補強材39と第1内側補強材41は、第1枠部31を介して建物躯体29に支持されている。第1枠部31には、第1外側補強材39または第1内側補強材41に覆われない部分が存在するが、その殆どは建物外装材67によって覆われ、外側からの延焼による直接的な影響は受けない。   The other end of the first inner reinforcing member 41 is fixed to the support piece 63 of the first frame portion 31 by a rivet 65 that is a fixing means. The base of the first frame portion 31 is fixed to the building frame 29. That is, the first outer reinforcing member 39 and the first inner reinforcing member 41 covering the first guide portion 27 are supported by the building frame 29 via the first frame portion 31. The first frame portion 31 includes a portion that is not covered by the first outer reinforcing member 39 or the first inner reinforcing member 41, but most of the portion is covered by the building exterior member 67, and is directly applied by fire spreading from the outside. Not affected.

また、第1ガイド部27と第1内側補強材41との間には空隙69が形成される。この空隙69は、断熱兼放熱層となる。空隙69を形成することで、第1ガイド部27からの熱を伝わりにくくし、かつ高温となった場合の第1ガイド部27の熱を放熱可能としている。   Further, a gap 69 is formed between the first guide portion 27 and the first inner reinforcing member 41. The gap 69 becomes a heat insulating and heat radiating layer. By forming the gap 69, heat from the first guide portion 27 is hardly transmitted, and heat of the first guide portion 27 when the temperature becomes high can be radiated.

第1外側補強材39の外側には化粧枠材である第1化粧枠材59が設けられ、第1化粧枠材59は第1外側補強材39を覆う。高温を遮断するために第1ガイド部27の外表面33を覆って設けられた第1外側補強材39が、さらにその外側に設けられた第1化粧枠材59によって覆われる。高温の阻止に特化された第1外側補強材39は、外観からは見えなくなる。このように、第1外側補強材39は、第1化粧枠材59で覆われるので、外部からは第1外側補強材39が見えなくなり、デザイン性を損ねることがない。   A first decorative frame material 59, which is a decorative frame material, is provided outside the first outer reinforcing material 39, and the first decorative frame material 59 covers the first outer reinforcing material 39. A first outer reinforcing member 39 provided so as to cover the outer surface 33 of the first guide portion 27 in order to block the high temperature is covered with a first decorative frame member 59 provided further outside. The first outer reinforcement 39 specialized for high temperature prevention is not visible from the exterior. Thus, since the 1st outer side reinforcement material 39 is covered with the 1st decorative frame material 59, the 1st outer side reinforcement material 39 becomes invisible from the outside, and design property is not impaired.

第1外側補強材39と、第1内側補強材41は鋼板よりなる。鋼板の板厚は0.8〜2mm程度が好適となる。あまり厚いと重量が増すためである。第1外側補強材39、第1内側補強材41は、第1ガイド部27に沿う方向が、全通しに連続であってもよいし、断続で複数で構成されてもよい。全通しのほうが、補強として、より効果的である。また、第1外側補強材39や第1内側補強材41は、第1ガイド部27の長手方向に複数に分割して製作すれば、製作、施工を容易にできる。第1外側補強材39は、帯状の鋼板を長手方向に沿う折り曲げ部71で折り曲げることで、出隅部37を覆うL字形に、安価かつ容易に製作可能となる。   The first outer reinforcing material 39 and the first inner reinforcing material 41 are made of steel plates. The plate thickness of the steel plate is preferably about 0.8 to 2 mm. This is because if it is too thick, the weight increases. The first outer reinforcing member 39 and the first inner reinforcing member 41 may be continuous in the direction along the first guide portion 27, or may be constituted by a plurality of intermittently. All-rounder is more effective as reinforcement. Moreover, if the 1st outer side reinforcement material 39 and the 1st inner side reinforcement material 41 are divided | segmented into several in the longitudinal direction of the 1st guide part 27, manufacture and construction can be made easy. The first outer reinforcing member 39 can be manufactured inexpensively and easily into an L-shape that covers the protruding corner portion 37 by bending a belt-shaped steel plate with a bending portion 71 along the longitudinal direction.

図4は外側補強材の掛かり代部73を説明する図2の要部拡大図である。
第1外側補強材39は、カーテン縁部45と重なる掛かり代部73を有する。アルミ合金製の第1ガイド部27は火災による熱で変形を起こし、さらには溶ける虞がある。また、抜け止め部材49は、樹脂製であり、耐風機能としては有効であるが、火災による熱で溶けて無くなってしまう虞がある。第1外側補強材39は、掛かり代部73が設けられていることで、カーテン縁部45の抜け止め部材49が溶けても、カーテン縁部45に重なる掛かり代部73を残すことができる。すなわち、左右のガイド部の間隔距離が、カーテン部13の幅長よりも短くなり、これにより、アルミ製の第1ガイド部27が熱で変形したり溶けたりしても、掛かり代部73がカーテン縁部に引っ掛かり、カーテン部13が第1ガイド部27から外れなくなる。このようにして、耐火材である第1外側補強材39の掛かり代部73で両側縁の掛かりを担保してカーテン部13の脱落を防ぐことができる。
FIG. 4 is an enlarged view of a main part of FIG. 2 for explaining the hook portion 73 of the outer reinforcing material.
The first outer reinforcing material 39 has a hook margin 73 that overlaps with the curtain edge 45. The first guide portion 27 made of aluminum alloy may be deformed by heat from a fire and may be melted. Further, the retaining member 49 is made of resin and is effective as a wind-resistant function, but may be lost due to melting by heat from a fire. Since the first outer reinforcing member 39 is provided with the hook margin 73, the hook margin 73 overlapping the curtain edge 45 can be left even if the retaining member 49 of the curtain edge 45 is melted. That is, the distance between the left and right guide portions is shorter than the width of the curtain portion 13, so that even when the first guide portion 27 made of aluminum is deformed or melted by heat, the hooking margin portion 73 is The curtain is caught on the edge of the curtain and the curtain 13 is not detached from the first guide 27. In this way, the hanging portion 73 of the first outer reinforcing material 39, which is a refractory material, can be secured at both side edges to prevent the curtain portion 13 from falling off.

In addition, since the reinforcing material retaining piece 153 is opposed to the inner side of the second guide portion reinforcing material 131, deformation due to high temperature does not occur, and the curtain portion 13 does not easily fall off, and the second guide portion reinforcing material 131 maintains the fitted state to the fourth guide part 125 by the locking tip edge part 149 and the fitting part 151 and delays deformation due to heating, and the second guide part reinforcing material 131 changes the shape of the fourth guide part 125. Let it be maintained. Further, by covering the inside of the fourth guide part 125 with the substantially U-shaped second guide part reinforcing material 131, the rigidity is further improved, and a bar or the like is provided in the gap between the slat 25 and the fourth guide part 125. It is possible to prevent the fourth guide portion 125 from being damaged by an illegal destructive action such as opening the plug, and the crime prevention performance is also improved.

なお、上記実施形態では、外側補強材、内側補強材、支持補強材として鋼板が使用される例を説明したが、これら部材はこの他、セラミックなどとすることもできる。また、例えば脱落などを起こさず補強することが可能なように、セラミックを吹き付けた他の素材との複合構造とすることもできる。また、化粧枠材は、不燃材料であればよく、アルミ合金以外のその他の素材であってもよい。   In addition, although the said embodiment demonstrated the example which uses a steel plate as an outer side reinforcement material, an inner side reinforcement material, and a support reinforcement material, these members can also be made into a ceramic etc. in addition to this. Moreover, it can also be set as the composite structure with the other raw material which sprayed the ceramic so that it can reinforce, for example, without dropping off. Further, the decorative frame material may be any non-combustible material, and may be other materials other than the aluminum alloy.
