Description

本発明は、耐火パネルの連結構造に関する。   The present invention relates to a connection structure for fireproof panels.

一般に、耐火建築物の間仕切壁には、耐火構造が求められる。パーティション式間仕切壁の場合、耐火性の間仕切壁(以下、耐火間仕切壁という場合がある)の芯材には、珪酸カルシウム板やロックウールボード等の不燃材料が使われることが多い。また、芯材を覆う化粧材には、壁材としての強度を持たせる目的で鋼板が使われることが多い。芯材への鋼板の固定方法としては、鋼板の端部を折り曲げ加工したものを芯材の両側に接着剤で全面接着することが多い。   Generally, a fireproof structure is required for a partition wall of a fireproof building. In the case of a partition-type partition wall, a non-combustible material such as a calcium silicate plate or rock wool board is often used for the core material of the fire-resistant partition wall (hereinafter sometimes referred to as a fire-resistant partition wall). In addition, a steel sheet is often used for the decorative material covering the core material for the purpose of providing strength as a wall material. As a method of fixing the steel plate to the core material, a material obtained by bending the end of the steel plate is often bonded to the entire surface of the core material with an adhesive.

耐火間仕切壁としては、耐火パネルを複数連結させたものが用いられている。耐火パネルの連結方法としては、サネ材によって連結する方法、小口に凹凸加工を施して嵌合する方法等が挙げられる。これらの方法等で複数連結された間仕切壁では、高温下での熱による鋼板の変形(所謂、熱伸び)の影響により、耐火パネルの連結部に隙間が生じ易く、該隙間から火炎や熱が漏れて延焼する虞があり、連結部は耐火性能上の弱点になり易い。また、高温下での熱によって芯材自体が変形すると、耐火パネル同士を連結しているサネ材が連結部から外れる、或いは耐火パネル同士の凹凸加工部分の嵌合が解除され、耐火パネルが倒れる、又は耐火間仕切壁が崩れる虞がある。さらに、鋼板を箱型に加工し、芯材全体を包み込むような形状にすると、火災時の加熱側の熱がパネル小口側の鋼板を熱橋として伝わるため、パネル接合部の温度が上がり易くなる虞がある。   As the fireproof partition wall, a plurality of fireproof panels connected together is used. As a method for connecting the fireproof panels, there are a method of connecting with a sap material, a method of fitting an unevenness to the edge, and the like. In the partition walls connected by a plurality of these methods, etc., due to the effect of deformation of the steel sheet due to heat at high temperature (so-called thermal elongation), a gap is easily generated in the connection part of the fireproof panel, and flame and heat are generated from the gap. There is a risk of fire spreading due to leakage, and the connecting part tends to be a weak point in fire resistance. In addition, when the core material itself is deformed by heat at a high temperature, the sap material connecting the refractory panels is detached from the connecting portion, or the fitting of the uneven processing portion between the refractory panels is released, and the refractory panel falls down. Or, there is a risk that the fireproof partition wall may collapse. Furthermore, if the steel plate is processed into a box shape and wrapped around the entire core material, the heat on the heating side during a fire is transferred as a steel bridge on the side edge of the panel as a thermal bridge, making it easier to raise the temperature at the panel joint. There is a fear.

上述のような事態に対処するために、火災側から非火災側に火炎や熱が漏れてしまうことを確実に防止可能な構造が開発されている。例えば、特許文献1には、二枚の金属製の表面板間に耐火断熱性の芯材を充填してなる耐火パネルの連結部構造(以下、単に連結部構造という場合がある)について開示されている。特許文献1に記載の連結部構造では、隣接する耐火パネルの芯材の連結側端面に、表面板と平行状の凹溝が形成されている。該凹溝には、表面板と平行状になるように珪酸カルシウム板が嵌合される一方、隣接する耐火パネルの表面板同士にパネル厚方向に重なり合って積層する積層部が設けられている。また、二枚の表面板は、凹溝までには至らない状態で連結側端面に沿うよう折曲されており、珪酸カルシウム板が凹溝に直接当接する状態で嵌合している一方、隣接する耐火パネルの連結側端面間同士は離間しており、対向面間に隙間が形成されている。前述の表面板は、連結側端面に沿う状態で凹溝側に向けて折曲したものが、凹溝に至る以前の段階で隣接耐火パネルの連結端面に向けて折曲して突出辺が形成されたものであり、隣接耐火パネルの突出辺同士は珪酸カルシウム板とは間隙を存した状態でパネル厚方向に積層された積層部となり、該積層部がケイ酸カルシウム板には至らない長さの螺子を用いて止着されている。   In order to cope with the above situation, a structure has been developed that can reliably prevent the leakage of flame and heat from the fire side to the non-fire side. For example, Patent Document 1 discloses a connection part structure of a fireproof panel in which a fireproof and heat insulating core material is filled between two metal surface plates (hereinafter sometimes simply referred to as a connection part structure). ing. In the connection part structure described in Patent Document 1, a concave groove parallel to the surface plate is formed on the connection side end face of the core material of the adjacent fireproof panel. In the concave groove, a calcium silicate plate is fitted so as to be parallel to the surface plate, and a laminated portion is provided to overlap and laminate the surface plates of the adjacent fireproof panels in the panel thickness direction. In addition, the two surface plates are bent along the connecting side end surface so as not to reach the concave groove, and the calcium silicate plate is fitted in a state of directly contacting the concave groove, while adjacent to each other. The end surfaces on the connection side of the fireproof panels are spaced apart, and a gap is formed between the opposing surfaces. The above-mentioned face plate is bent toward the concave groove side along the connection side end surface, but is bent toward the connection end surface of the adjacent fireproof panel before reaching the concave groove to form a protruding side. The projecting sides of adjacent fireproof panels are laminated parts that are laminated in the panel thickness direction with a gap from the calcium silicate board, and the laminated part has a length that does not reach the calcium silicate board. It is fastened using a screw.

特許第5721383号公報Japanese Patent No. 5721383

しかしながら、特許文献1に記載の連結部構造では、芯材にあまり耐火性能が高くないロックウールボードを使用しているため、耐火性能を担保するために必要なパネルの厚みが厚くなる。芯材として使用されているロックウールボードの密度は不燃材料の中では比較的軽い方であるが、前述のように厚みが厚くなるので、耐火パネルの重量増大は免れない。また、サネ材に使用している珪酸カルシウム板の厚みは一般的な鋼板の厚みよりも厚く、必然的に耐火パネルの厚みはより一層厚くなる。このような事情から、特許文献1に記載の連結部構造では、耐火パネルの重量が重くなってしまうという問題があった。そのため、耐火間仕切壁の施工現場では、揚重設備を用いざるを得ず、工数と労力がかかる虞があった。
また、特許文献1に記載の連結部構造では、火災側からの熱により、表面板(化粧材)が熱伸びし、変形することで、火災側の耐火パネルの芯材と表面板との間に火炎の通り道となる隙間が生じてしまうという問題があった。
However, in the connection part structure of patent document 1, since the rock wool board which is not so high in fireproof performance is used for a core material, the thickness of the panel required in order to ensure fireproof performance becomes thick. The density of the rock wool board used as the core material is relatively light among non-combustible materials, but since the thickness is increased as described above, an increase in the weight of the fireproof panel is inevitable. Further, the thickness of the calcium silicate plate used for the sap material is thicker than that of a general steel plate, and the thickness of the fireproof panel is inevitably thicker. Under such circumstances, the connection part structure described in Patent Document 1 has a problem that the weight of the fireproof panel is increased. For this reason, in the construction site of the fireproof partition wall, it is necessary to use lifting equipment, and there is a risk that man-hours and labor may be required.
Moreover, in the connection part structure of patent document 1, with the heat from a fire side, a surface board (decorative material) heat-extends and deform | transforms, and it is between a core material and surface board of a fire side fireproof panel. There was a problem that a gap was formed as a passage for the flame.

本発明は、上記事情に鑑みてなされたものであり、耐火パネルの軽量化を図ると共に、耐火パネル同士の連結をより強固に保持し、非火災側への延焼を抑えることができる耐火パネルの連結構造(間仕切壁)を提供する。   The present invention has been made in view of the above circumstances, and while reducing the weight of the fireproof panel, more firmly holding the connection between the fireproof panels and suppressing the spread of fire to the non-fire side. A connecting structure (partition wall) is provided.

請求項1記載の耐火パネルの連結構造は、耐火パネルが複数連結されている耐火パネルの連結構造であって、前記耐火パネルは、珪酸カルシウムを含む板状の芯材と、前記芯材の側面に形成された凹溝と、前記凹溝に嵌合する凹溝嵌合部と該凹溝嵌合部の両端から前記芯材の側面に沿うように延設された延設部とを有する鋼製部材と、前記芯材の表面及び側面の一部を覆い、留付材によって前記鋼製部材に連結している鋼板と、を備え、前記凹溝嵌合部にサネ材が嵌合されていることを特徴とする。   The fireproof panel connection structure according to claim 1 is a fireproof panel connection structure in which a plurality of fireproof panels are connected, and the fireproof panel includes a plate-like core material containing calcium silicate and a side surface of the core material. Steel having a groove formed in the groove, a groove fitting portion that fits into the groove, and an extending portion that extends from both ends of the groove fitting portion along the side surface of the core material. And a steel plate that covers a part of the surface and side surfaces of the core material and is connected to the steel member by a fastening material, and a sap material is fitted into the concave groove fitting portion. It is characterized by being.

上述の構成によれば、芯材に耐火性能が高く、軽量な珪酸カルシウムを含む芯材を使用することによって、耐火パネルの軽量化が図られる。
また、耐火パネルに鋼製部材が設けられていることによって、火災初期には火災側の耐火パネルの表面の鋼板の熱伸びによる変形のスパンが小さくなり、鋼製部材とサネ材との嵌合状態が持続されるので、耐火パネル同士の連結がより強固に保持される。
さらに、鋼製部材と鋼板とが耐火パネルの側面で留付材によって連結されていることによって、火災後期には鋼製部材が鋼板と連動し、火災側に引っ張られ、鋼製部材の形状が変化し、鋼製部材の凹溝嵌合部の底部近傍がサネ材の両端部を締め上げる。これにより、サネ材が凹溝嵌合部から抜け難くなり、鋼製部材とサネ材との嵌合状態が持続されるので、耐火パネル同士の連結がより強固に保持される。
According to the above-described configuration, the fireproof panel can be reduced in weight by using a core material that has a high fire resistance performance and includes light calcium silicate.
In addition, because the steel member is provided on the fireproof panel, the deformation span due to the thermal expansion of the steel plate on the surface of the fireside fireproof panel is reduced in the early stage of the fire, and the steel member and the steel material are fitted. Since the state is maintained, the connection between the fireproof panels is more firmly maintained.
Furthermore, since the steel member and the steel plate are connected by the fastening material on the side of the fireproof panel, the steel member is interlocked with the steel plate in the late stage of the fire and pulled to the fire side, and the shape of the steel member is It changes, and the bottom part vicinity of the ditch | groove fitting part of a steel member tightens up the both ends of a steel material. Thereby, it becomes difficult for the steel material to come out of the recessed groove fitting portion, and the fitting state between the steel member and the steel material is maintained, so that the connection between the fireproof panels is more firmly maintained.

請求項2記載の耐火パネルの連結構造では、請求項2記載の耐火パネルの連結構造において、前記鋼製部材が前記芯材の側面に複数設けられていてもよい。   In the fireproof panel connection structure according to claim 2, in the fireproof panel connection structure according to claim 2, a plurality of the steel members may be provided on a side surface of the core member.

上述の構成によれば、鋼製部材の高さ寸法が施工時に扱いやすい程度に抑えられ、そのような鋼製部材が互いに間隔をあけて芯材の側面に複数設けられる。これにより、芯材の側面の高さの全長にわたるような長い鋼製部材を扱わなくても済み、且つ、鋼製部材とサネ材との嵌合状態は持続される。従って、耐火パネル同士の連結は良好に保持される。   According to the above-described configuration, the height of the steel member is suppressed to such an extent that it can be easily handled at the time of construction, and a plurality of such steel members are provided on the side surface of the core member at intervals. Thereby, it is not necessary to handle a long steel member that covers the entire length of the side surface of the core material, and the fitting state between the steel member and the sap material is maintained. Therefore, the connection between the fireproof panels is maintained well.

本発明の耐火パネルの連結構造によれば、耐火パネルの軽量化を図ると共に、耐火パネル同士の連結をより強固に保持することができる。   According to the connection structure of the fireproof panels of the present invention, it is possible to reduce the weight of the fireproof panels and more firmly hold the connections between the fireproof panels.

以下、本発明を適用した耐火パネルの連結構造の一実施形態(以下、本実施形態の耐火パネルの連結構造とすることがある)について、図面を参照して説明する。なお、以下の説明で用いる図面は模式的なものであり、長さ、幅及び厚みの比率等は実際のものと同一とは限らず、適宜変更することができる。   Hereinafter, one embodiment of a fireproof panel connection structure to which the present invention is applied (hereinafter, sometimes referred to as a fireproof panel connection structure of the present embodiment) will be described with reference to the drawings. Note that the drawings used in the following description are schematic, and the ratios of length, width, and thickness are not necessarily the same as actual ones, and can be changed as appropriate.

始めに、本実施形態の耐火パネルの連結構造20について説明する。
図1に示すように、本実施形態の耐火パネルの補強構造20は、不図示の耐火建築物内に設けられた耐火間仕切壁であって、複数枚の耐火パネル2を後述するサネ材28によって耐火パネル2の幅方向に連結することで形成されている。なお、図1では、サネ材28及び耐火パネル2同士の連結部分の詳細な図示を省略する。
First, the connection structure 20 of the fireproof panel of this embodiment is demonstrated.
As shown in FIG. 1, the fireproof panel reinforcing structure 20 of the present embodiment is a fireproof partition wall provided in a fireproof building (not shown). It is formed by connecting in the width direction of the fireproof panel 2. In addition, in FIG. 1, detailed illustration of the connection part of the frame material 28 and the fireproof panels 2 is abbreviate | omitted.

耐火パネル2は、天井部に設けられた天井レール4と、床部に設けられた床レール6に嵌められ、支持されている。複数枚の耐火パネル2うち幅方向両側に配置された耐火パネル2,2は、天井レール4及び床レール6に加えて不図示の壁面に設けられた壁レール(図示略)に嵌められ、支持されている。   The fireproof panel 2 is fitted and supported on a ceiling rail 4 provided on the ceiling and a floor rail 6 provided on the floor. Among the plurality of fireproof panels 2, fireproof panels 2 and 2 arranged on both sides in the width direction are fitted and supported by a wall rail (not shown) provided on a wall surface (not shown) in addition to the ceiling rail 4 and the floor rail 6. Has been.

本実施形態では、図2及び図3に示すように、耐火パネル2の厚み方向において互いに当接するように複数枚の耐火パネル2が二列に配置され、且つ各列の耐火パネル2同士の連結部の位置が耐火パネル2の幅方向においてずれている。即ち、複数枚の耐火パネル2は、二層の千鳥配置をなしている。このような構成により、万一、一方の耐火パネル2の列に火炎の通り道となる隙間が生じても、他方の耐火パネル2の列への延焼が抑えられる。   In the present embodiment, as shown in FIGS. 2 and 3, a plurality of fireproof panels 2 are arranged in two rows so as to contact each other in the thickness direction of the fireproof panels 2, and the fireproof panels 2 in each row are connected to each other. The position of the part is shifted in the width direction of the fireproof panel 2. That is, the plurality of refractory panels 2 have a two-layer zigzag arrangement. With such a configuration, even if a gap serving as a passage for a flame is generated in one row of the refractory panels 2, the spread of fire to the other refractory panel 2 row is suppressed.

図3に示すように、二層の千鳥配置で構成された複数枚の耐火パネル2を支持するための天井レール4は、略直角に屈曲した形状を有し、ビス35によって天井部壁面44に固定された取付金具34で構成されている。同様に、床レール6は、略直角に屈曲した形状を有し、ビス37によって床面46に固定された取付金具36で構成されている。
なお、耐火パネル2の各レールへの取付方法や天井レール4、床レール6及び壁レールの構造は、耐火パネルの連結構造20の施工時に、耐火パネル2を嵌めて所定の位置まで幅方向にスライドさせ、設置位置でビス等により固定可能であることが好ましいが、特に限定されない。
As shown in FIG. 3, the ceiling rail 4 for supporting a plurality of fireproof panels 2 configured in a two-layer zigzag arrangement has a shape bent substantially at a right angle, and is attached to the ceiling wall surface 44 by screws 35. It is composed of a fixed mounting bracket 34. Similarly, the floor rail 6 has a shape bent substantially at a right angle, and includes a mounting bracket 36 fixed to the floor surface 46 by screws 37.
The method of attaching the fireproof panel 2 to each rail and the structure of the ceiling rail 4, the floor rail 6 and the wall rail are as follows. Although it is preferable that it can be slid and fixed with a screw or the like at the installation position, it is not particularly limited.

図2に示すように、耐火パネル2は、芯材5と、芯材5の側面5dに形成された凹溝7と、凹溝7に嵌合する凹溝嵌合部8と凹溝嵌合部8の両端部8e,8eから芯材5の側面5dに沿うように延設された延設部10とを有する鋼製部材12と、芯材5の表面5a,5b及び側面5dの一部を覆い、鋼製部材12に接続されている鋼板15と、を備えている。   As shown in FIG. 2, the fireproof panel 2 includes a core member 5, a groove 7 formed on the side surface 5 d of the core member 5, a groove fitting portion 8 that fits into the groove 7, and a groove fitting. A steel member 12 having an extending portion 10 extending from both end portions 8e, 8e of the portion 8 along the side surface 5d of the core material 5, and a part of the surfaces 5a, 5b and the side surface 5d of the core material 5 And a steel plate 15 connected to the steel member 12.

芯材5は、珪酸カルシウムを含む板状部材である。珪酸カルシウムを含む板状部材としては耐火性及び軽量性の観点から,珪酸カルシウム板やALC板などが利用でき,特にJIS A 5430の中のタイプ3の珪酸カルシウム板が好ましく,その中でも0.2TKの略号で示される珪酸カルシウム板がより好ましい。本実施形態では、芯材5は耐火性能が高く、軽量な珪酸カルシウム板(JIS A 5430における0.2TK)で構成されている。芯材5の幅は、300mmから600mm程度であり、600mm以下であることが好ましい。芯材5の幅が600mmより大きくなると、火災時に鋼板15が熱伸びする際の歪みが大きくなるため、鋼製部材12によって鋼板15が固定された状態を持続するのが難しくなる虞がある。   The core material 5 is a plate-like member containing calcium silicate. As a plate-like member containing calcium silicate, a calcium silicate plate or an ALC plate can be used from the viewpoint of fire resistance and lightness, and in particular, a type 3 calcium silicate plate in JIS A 5430 is preferable, and among them, 0.2 TK A calcium silicate plate represented by the abbreviation is more preferable. In the present embodiment, the core material 5 has a high fire resistance and is made of a lightweight calcium silicate plate (0.2 TK in JIS A 5430). The width of the core material 5 is about 300 mm to 600 mm, and preferably 600 mm or less. If the width of the core material 5 is greater than 600 mm, the strain when the steel plate 15 is thermally stretched during a fire increases, and it may be difficult to maintain the state in which the steel plate 15 is fixed by the steel member 12.

図4に示すように、鋼製部材12は金属の鋼板をハット形状に折り曲げ加工した部材である。鋼製部材12としては、例えば溶融亜鉛めっき鋼板(JIS G 3302)や、溶融55%アルミニウム−亜鉛合金めっき鋼板(JIS G 3321)等が好適である。鋼製部材12の厚み寸法Tは、0.27mm以上0.3mm以下であることが好ましい。鋼製部材12の厚み寸法Tが0.3mmより厚くなると、凹溝7への嵌合時に支障をきたす。また、鋼製部材12の厚み寸法Tが0.27mmより薄くなると、火災時に鋼板15が熱伸びする際の歪が大きくなるため、鋼製部材12によって鋼板15が固定された状態を持続するのが難しくなる虞がある。   As shown in FIG. 4, the steel member 12 is a member obtained by bending a metal steel plate into a hat shape. As the steel member 12, for example, a hot dip galvanized steel sheet (JIS G 3302), a molten 55% aluminum-zinc alloy plated steel sheet (JIS G 3321), and the like are suitable. The thickness dimension T of the steel member 12 is preferably 0.27 mm or more and 0.3 mm or less. When the thickness dimension T of the steel member 12 becomes thicker than 0.3 mm, it causes troubles when fitting into the concave groove 7. Further, when the thickness dimension T of the steel member 12 is less than 0.27 mm, since the distortion when the steel plate 15 is thermally stretched during a fire increases, the state where the steel plate 15 is fixed by the steel member 12 is maintained. May become difficult.

図2に示すように、凹溝7は、芯材5の側面5dにおいて、芯材5の厚み方向略中央に位置し、芯材5の高さ方向全長に亘って形成されている。
鋼製部材12の凹溝嵌合部8は、凹溝7の形状に合わせて形成され、凹溝7への嵌合時には凹溝7の内壁面に当接している。
As shown in FIG. 2, the concave groove 7 is located substantially at the center in the thickness direction of the core material 5 on the side surface 5 d of the core material 5 and is formed over the entire length in the height direction of the core material 5.
The concave groove fitting portion 8 of the steel member 12 is formed in accordance with the shape of the concave groove 7, and is in contact with the inner wall surface of the concave groove 7 when fitted into the concave groove 7.

図2及び図3に示すように、鋼製部材12の延設部10は、凹溝嵌合部8に連設され、芯材5の側面5dから見て凹溝嵌合部8の側方の端部8eから芯材5の側面5dに沿って折り返すように形成され、端部8eと表面5a,5b及び側面5dの接続部との略中央まで延びている。鋼製部材12の高さ寸法は、例えば10mmから30mm程度であることが好ましく、15mmから20mm程度であることがより好ましい。
鋼製部材12の高さ寸法が10mmより短い場合、火災時に鋼板15が固定された状態を持続するのが難しくなる虞がある。また、高さ寸法が30mmより長い場合、火災時に鋼板15が固定された状態を持続することは可能であるが、鋼製部材12が熱橋になり、パネル目地部の耐火性能を担保出来ない虞がある。
As shown in FIGS. 2 and 3, the extending portion 10 of the steel member 12 is connected to the concave groove fitting portion 8, and is lateral to the concave groove fitting portion 8 when viewed from the side surface 5 d of the core material 5. The end portion 8e is formed so as to be folded back along the side surface 5d of the core member 5, and extends to substantially the center between the end portion 8e and the connecting portions of the surfaces 5a and 5b and the side surface 5d. The height dimension of the steel member 12 is preferably about 10 mm to 30 mm, for example, and more preferably about 15 mm to 20 mm.
When the height dimension of the steel member 12 is shorter than 10 mm, it may be difficult to maintain the state in which the steel plate 15 is fixed in a fire. Moreover, when the height dimension is longer than 30 mm, it is possible to maintain the state in which the steel plate 15 is fixed at the time of a fire, but the steel member 12 becomes a thermal bridge, and the fire resistance performance of the panel joint cannot be ensured. There is a fear.

上述のように所謂ハット型に形成されている鋼製部材12は、芯材5の高さ方向において、所定の間隔をあけて複数設けられている。鋼製部材12同士の間隔は、例えば300mmから600mm程度であることが好ましく、450mm程度であることがより好ましい。鋼製部材12同士の間隔が300mmより狭いと、火災初期の鋼板の熱伸びによる変形のスパンは更に小さくなり、火災後期のサネ材の嵌合状態が持続されやすくなるが、鋼製部材12が熱橋になり、パネル目地部の耐火性能を担保出来ない虞がある。また、鋼製部材12同士の間隔が600mmより広いと、火災初期の鋼板の熱伸びによる変形のスパンが大きくなり、火災後期のサネ材両端部を締め上げる力が弱くなるため、嵌合状態が持続されにくくなる。   As described above, a plurality of steel members 12 formed in a so-called hat shape are provided at predetermined intervals in the height direction of the core member 5. The distance between the steel members 12 is preferably, for example, about 300 mm to 600 mm, and more preferably about 450 mm. If the distance between the steel members 12 is smaller than 300 mm, the deformation span due to the thermal elongation of the steel plate in the early stage of the fire is further reduced, and the fitting state of the steel material in the late stage of the fire is easily maintained. There is a possibility that it becomes a thermal bridge and the fire resistance performance of the panel joint cannot be secured. Moreover, if the distance between the steel members 12 is wider than 600 mm, the deformation span due to the thermal elongation of the steel plate in the early stage of the fire becomes large, and the force to tighten both ends of the sap material in the late stage of the fire becomes weak. It becomes difficult to be sustained.

鋼板15は、芯材5の表面5a又は表面5bを被覆可能に形成された鋼板15a,15bで構成されている。鋼板15は、芯材5の表面5a又は表面5bの側端部から芯材5の側面5dに沿って折り返すように形成され、鋼製部材12の延設部10に留付材によって接続されている。留付材としては、ブラインドリベットや、ビス等が挙げられ、スポット溶接等も含むが、鋼製部材12と鋼板15とを接続可能とするものであれば特に限定されない。鋼板15と芯材5及び鋼製部材12の延設部10とは、アクリル系樹脂、ウレタン系樹脂、酢酸ビニル系樹脂、エポキシ系樹脂等の塗料(図示略)によって接着されている。   The steel plate 15 is composed of steel plates 15a and 15b formed so as to be able to cover the surface 5a or the surface 5b of the core material 5. The steel plate 15 is formed so as to be folded back along the side surface 5d of the core material 5 from the side end portion of the surface 5a or the surface 5b of the core material 5 and connected to the extending portion 10 of the steel member 12 by a fastening material. Yes. Examples of the fastening material include blind rivets and screws, and include spot welding. However, the fastening material is not particularly limited as long as the steel member 12 and the steel plate 15 can be connected. The steel plate 15, the core material 5, and the extending portion 10 of the steel member 12 are bonded by a paint (not shown) such as an acrylic resin, a urethane resin, a vinyl acetate resin, or an epoxy resin.

鋼板15としては、例えば溶融55%アルミニウム−亜鉛合金めっき鋼板(JIS G 3321)や、塗装溶融55%アルミニウム−亜鉛合金めっき鋼板(JIS G 3322)、溶融亜鉛めっき鋼板(JIS G 3302)、塗装溶融亜鉛めっき鋼板(JIS G 3312)等が好適である。鋼板15の厚み寸法は、0.3mmから0,5mm程度であり、0.35mm前後であることが好ましい。なお、鋼板15は、通常用いられている鋼板で構成されていても構わない。
鋼板15及び芯材5を合わせた耐火パネル2の厚みは、耐火パネル2の耐火性を高めると共に施工性を高め、且つ軽量化を確実に図る点から、26mm程度とされている。
Examples of the steel plate 15 include a molten 55% aluminum-zinc alloy plated steel plate (JIS G 3321), a coated molten 55% aluminum-zinc alloy plated steel plate (JIS G 3322), a hot dip galvanized steel plate (JIS G 3302), and a coating melt. A galvanized steel sheet (JIS G 3312) or the like is suitable. The thickness dimension of the steel plate 15 is about 0.3 mm to 0.5 mm, and is preferably around 0.35 mm. In addition, the steel plate 15 may be comprised with the steel plate normally used.
The thickness of the fireproof panel 2 including the steel plate 15 and the core material 5 is about 26 mm from the viewpoint of enhancing the fire resistance of the fireproof panel 2 and improving the workability and reliably reducing the weight.

図2に示すように、鋼製部材12の凹溝嵌合部8には、複数枚の耐火パネル2同士の連結用部材であるサネ材28が嵌合されている。サネ材28は、少なくともサネ材28の幅方向の両端部28e,28eを鋼製部材12の凹溝嵌合部8に収容可能に形成された板状部材である。サネ材28は基本的に鋼製であり、サネ材28の素材としては鋼板15と同様の素材を例示することができる。サネ材28の幅は、26mmから37mmの範囲内であることが好ましい。サネ材28の厚みは、1.6mmから3.6mm程度であり、2.3mm前後であることが好ましい。   As shown in FIG. 2, a sag material 28, which is a member for connecting a plurality of fireproof panels 2, is fitted into the recessed groove fitting portion 8 of the steel member 12. The sap material 28 is a plate-like member formed so that at least both end portions 28 e and 28 e in the width direction of the sap material 28 can be accommodated in the recessed groove fitting portion 8 of the steel member 12. The sap material 28 is basically made of steel, and the sap material 28 can be exemplified by the same material as the steel plate 15. The width of the sap material 28 is preferably in the range of 26 mm to 37 mm. The thickness of the steel material 28 is about 1.6 mm to 3.6 mm, and is preferably about 2.3 mm.

次いで、本実施形態の耐火パネルの連結構造20の施工工法について説明する。
先ず、芯材5の側面5dに凹溝7を形成し、鋼製部材12の凹溝嵌合部8を凹溝7に差し込み、仮止めする。芯材5の高さ方向において、所定の間隔をあけて複数の鋼製部材12を仮止めしておく。
Next, the construction method of the fireproof panel connection structure 20 of the present embodiment will be described.
First, the groove 7 is formed in the side surface 5d of the core material 5, and the groove fitting portion 8 of the steel member 12 is inserted into the groove 7 and temporarily fixed. In the height direction of the core material 5, a plurality of steel members 12 are temporarily fixed at predetermined intervals.

次に、鋼板15を芯材5の表面5a,5b及び側面5dの一部及び鋼製部材12の延設部10を覆うようにこれらの面に当接させ、前述のアクリル系樹脂等の塗料によって、芯材5及び鋼製部材12に密着させる。ここまでの工程により、耐火パネル2が完成する。
なお、ここまでの工程は、施工現場で行ってもよく、各種必要な部材を施工現場に運搬する前に工場等において予め行い、組み立て後の耐火パネル2を施工現場に持ち込んでもよい。
Next, the steel plate 15 is brought into contact with these surfaces so as to cover the surfaces 5a and 5b and a part of the side surface 5d of the core material 5 and the extending portion 10 of the steel member 12, and the paint such as the acrylic resin described above is used. Thus, the core member 5 and the steel member 12 are brought into close contact with each other. The fireproof panel 2 is completed through the steps so far.
In addition, the process so far may be performed at a construction site, or may be performed in advance in a factory or the like before various necessary members are transported to the construction site, and the assembled fireproof panel 2 may be brought into the construction site.

次に、耐火パネル2を耐火性建物の天井レール4及び床レール6に嵌め込み、所定の位置に配置し(例えば、壁側に寄せ)、続いてその耐火パネル2に隣り合う耐火パネル2を配置する。図5に示すように、隣り合う耐火パネル2A,2Bのうち耐火パネル2Aの鋼製部材12の凹溝嵌合部8にサネ材28の一方の端部28eを嵌め込む。その後、耐火パネル2Aから突出しているサネ材28の他方の端部28eに鋼製部材12の凹溝嵌合部8が嵌合するように、耐火パネル2Bを連結させる。なお、図5では、わかりやすくするために、一列分の耐火パネル2,2同士の連結についてのみ示すが、上述したように複数枚の耐火パネル2を二層の千鳥配置にすることもでき、三層以上の複数層で構成してもよい。
以上の工程により耐火パネルの連結構造20が完成し、以上の工程を耐火パネル2の枚数に応じて繰り返し行うと、耐火間仕切壁が完成する。
Next, the fireproof panel 2 is fitted into the ceiling rail 4 and the floor rail 6 of the fireproof building and arranged at a predetermined position (for example, close to the wall side), and then the fireproof panel 2 adjacent to the fireproof panel 2 is arranged. To do. As shown in FIG. 5, one end portion 28e of the sap material 28 is fitted into the recessed groove fitting portion 8 of the steel member 12 of the refractory panel 2A among the adjacent refractory panels 2A and 2B. Then, the fireproof panel 2B is connected so that the concave groove fitting portion 8 of the steel member 12 is fitted to the other end portion 28e of the steel member 28 protruding from the fireproof panel 2A. In FIG. 5, only the connection between the fireproof panels 2 and 2 for one row is shown for the sake of clarity. However, as described above, a plurality of fireproof panels 2 can be arranged in a two-layered staggered arrangement, You may comprise in multiple layers of three or more layers.
The fireproof panel connection structure 20 is completed through the above steps, and the fireproof partition walls are completed when the above steps are repeated according to the number of fireproof panels 2.

以上説明したように、本実施形態の耐火パネルの連結構造20によれば、芯材5が珪酸カルシウムを含み、具体的には珪酸カルシウム板であるため、耐火パネル2に優れた耐火性能を付与すると共に、耐火パネル2の軽量化を図ることができる。具体的には、一枚の耐火パネル2の幅寸法を600mm、高さ寸法を4000mmとすると、耐火パネル2の重量を最大でも約35kgにし、従来の耐火パネルの半分程度まで抑えることができる。
そして、揚重設備を用いずに施工できるので、建設コストの削減も図ることができる。
As described above, according to the connection structure 20 of the fireproof panel of the present embodiment, the core material 5 includes calcium silicate, specifically, a calcium silicate plate, so that excellent fireproof performance is imparted to the fireproof panel 2. In addition, the weight of the fireproof panel 2 can be reduced. Specifically, when the width dimension of one fireproof panel 2 is 600 mm and the height dimension is 4000 mm, the weight of the fireproof panel 2 can be about 35 kg at the maximum, and can be suppressed to about half of the conventional fireproof panel.
And since it can construct without using a lifting equipment, construction cost can also be reduced.

また、本実施形態の耐火パネルの連結構造20によれば、耐火パネル2が鋼製部材12及び鋼板15を備えているので、鋼板15は耐火パネル2の高さ方向において所定の間隔毎に鋼製部材12に接続されている。従って、例えば火災初期には、図5に示すように、火災側の耐火パネル2の表面の鋼板15が熱伸びする際に、鋼製部材12に固定されている箇所の鋼板15は、火災側の耐火パネル2の表面の鋼板15より熱を受けていない鋼製部材12によって芯材5側に引き付けられることで、火災側の耐火パネル2の表面の鋼板15の熱伸びによる変形のスパンが小さくなる。これにより、火炎の通り道となる隙間が生じる危険性を下げ、非火災側への延焼を抑えることができる。また、図6に示すように、火災初期では、鋼製部材12の変形も少ないため、鋼製部材12とサネ材28との嵌合状態が持続されるので、耐火パネル2,2同士の連結をより強固に保持することができる。その結果、耐火パネルの連結構造20及びこれを用いた耐火間仕切壁の崩壊を防止し、非火災側への延焼を抑えることができる。   Moreover, according to the fireproof panel connection structure 20 of the present embodiment, since the fireproof panel 2 includes the steel member 12 and the steel plate 15, the steel plate 15 is made of steel at a predetermined interval in the height direction of the fireproof panel 2. It is connected to the member 12. Therefore, for example, at the beginning of the fire, as shown in FIG. 5, when the steel plate 15 on the surface of the fireproof panel 2 on the fire side thermally expands, the steel plate 15 at the place fixed to the steel member 12 is By being attracted to the core material 5 side by the steel member 12 not receiving heat from the steel plate 15 on the surface of the fireproof panel 2, the deformation span due to the thermal elongation of the steel plate 15 on the surface of the fireproof panel 2 on the fire side is small. Become. Thereby, the danger that the clearance gap used as the path of a flame will arise can be reduced, and the fire spread to the non-fire side can be suppressed. In addition, as shown in FIG. 6, since the deformation of the steel member 12 is small at the initial stage of the fire, the fitting state between the steel member 12 and the steel material 28 is maintained, so that the fireproof panels 2 and 2 are connected to each other. Can be held more firmly. As a result, it is possible to prevent the fireproof panel connection structure 20 and the fireproof partition wall using the fireproof panel from collapsing, and to suppress the spread of fire to the non-fire side.

また、本実施形態の耐火パネルの連結構造20によれば、上述のように鋼板15は耐火パネル2の高さ方向において所定の間隔毎に鋼製部材12に接続されているので、例えば火災後期には鋼製部材12に熱が伝わり、鋼製部材12も熱伸びし、鋼板15と連動する。従って、図7及び図8に示すように鋼製部材12の形状が変化し、鋼製部材12の凹溝嵌合部8の底部近傍が隣り合う耐火パネル2,2同士の連結部中心に向かう方向(即ち、図8に示すD12方向)及び芯材5の表面5a,5bが押し合う方向(即ち、図8に示すD5方向)にサネ材28の両端部28e,28eを締め上げる。このようにD5方向,D12方向に締め上げられることにより、サネ材28が鋼製部材12の凹溝嵌合部8から抜け難くなると共に、サネ材28が自立するように支持され、鋼製部材12とサネ材28との嵌合状態が持続されるので、耐火パネル2,2同士の連結をより強固に保持することができる。その結果、火災後期であっても、耐火パネルの連結構造20及びこれを用いた耐火間仕切壁の崩壊を防止し、非火災側への延焼を抑えることができる。   Also, according to the fireproof panel connection structure 20 of the present embodiment, the steel plate 15 is connected to the steel member 12 at predetermined intervals in the height direction of the fireproof panel 2 as described above. In this case, heat is transmitted to the steel member 12, the steel member 12 is also thermally expanded, and interlocks with the steel plate 15. Therefore, as shown in FIGS. 7 and 8, the shape of the steel member 12 changes, and the vicinity of the bottom of the recessed groove fitting portion 8 of the steel member 12 moves toward the center of the connecting portion between the adjacent fireproof panels 2 and 2. Both ends 28e, 28e of the sap material 28 are tightened in the direction (ie, the direction D12 shown in FIG. 8) and the direction in which the surfaces 5a, 5b of the core material 5 are pressed together (ie, the direction D5 shown in FIG. 8). By being tightened in the D5 direction and the D12 direction in this way, the sap material 28 becomes difficult to come out of the recessed groove fitting portion 8 of the steel member 12, and the sap material 28 is supported so as to be self-supporting, and the steel member. Since the fitting state of 12 and the sap material 28 is maintained, the connection between the fireproof panels 2 and 2 can be held more firmly. As a result, it is possible to prevent the fireproof panel connection structure 20 and the fireproof partition wall using the fireproof panel from collapsing even in the latter half of the fire, and to suppress the spread of fire to the non-fire side.

また、本実施形態の耐火パネルの連結構造20によれば、軽量な耐火パネル2同士を耐火性のサネ材28を介して連結するので、耐火パネル2同士の連結部の隙間にもサネ材28が配置され、連結部からの火炎や熱の通過を抑制することができる。また、耐火パネルの連結構造20や耐火間仕切壁の組み立て施工が容易となり、建設コストの削減をさらに図ることができる。   Moreover, according to the connection structure 20 of the fireproof panel of this embodiment, since the lightweight fireproof panels 2 are connected through the fireproof sap material 28, the sap material 28 is also provided in the gap between the connection parts of the refractory panels 2. Is arranged, and the passage of flame and heat from the connecting portion can be suppressed. In addition, the assembly construction of the fireproof panel connection structure 20 and the fireproof partition walls is facilitated, and the construction cost can be further reduced.

さらに、本実施形態の耐火パネルの連結構造20は、上述のように耐火性を有すると共に軽くて薄い耐火パネル2を用いると共に、非火災側への延焼を確実に抑えることができることから、災害弱者施設の間仕切壁に使用することができる。そして、意匠性を確保しつつ、火災時の延焼防止性を一般の防火区画同様に維持できるため、安全性の高い建物の提供が可能となる。   Furthermore, the fireproof panel connection structure 20 of the present embodiment uses the light and thin fireproof panel 2 having fire resistance as described above, and can reliably suppress the spread of fire to the non-fire side. Can be used for facility partition walls. And since the fire spread prevention property at the time of a fire can be maintained like a general fire prevention zone, ensuring designability, provision of a highly safe building is attained.

以上、本発明の好ましい実施形態について詳述したが、本発明は係る特定の実施形態に限定されるものではなく、特許請求の範囲内に記載された本発明の要旨の範囲内において、種々の変更が可能である。   The preferred embodiment of the present invention has been described in detail above, but the present invention is not limited to the specific embodiment, and various modifications can be made within the scope of the present invention described in the claims. It can be changed.

また、耐火パネル2は、天井レール4や床レール6に限定されず、建物の梁や柱に支持されていても構わない。即ち、建物の梁や柱における耐火パネル2との対向面に凹溝7が形成され、凹溝7に鋼製部材12が嵌合され、耐火パネル2と梁又は柱がサネ材28によって連結されていてもよい。   Moreover, the fireproof panel 2 is not limited to the ceiling rail 4 or the floor rail 6, and may be supported by a beam or a column of the building. That is, the groove 7 is formed on the surface of the building beam or column facing the fireproof panel 2, the steel member 12 is fitted into the groove 7, and the fireproof panel 2 and the beam or column are connected by the sash 28. It may be.

また、芯材5の珪酸カルシウム板には、目地が設けられていてもよい。目地を設けた場合には、目地を通じて火災側から非火災側に火炎や熱が漏れることを防止する観点から、突合せ部に耐火性の接着剤を塗布することが好ましい。
鋼板15には、オレフィン系等の化粧シートが貼り付けられていてもよい。 また、鋼板15を白やグレー、その他の単色系のカラー鋼板仕様とするだけではなく、鋼板15の化粧仕上げとして、前述のオレフィン系、塩化ビニル系等の樹脂系フィルムに印刷加工を施した化粧シートを表面15a,15bに貼ることで、意匠性を付与したパネルとして、インテリア用途を含めた鋼板15の使用範囲を広げることができる。
The calcium silicate plate of the core material 5 may be provided with joints. When the joint is provided, it is preferable to apply a fire-resistant adhesive to the butt portion from the viewpoint of preventing a flame or heat from leaking from the fire side to the non-fire side through the joint.
An olefin-based decorative sheet may be attached to the steel plate 15. In addition, the steel plate 15 is not only made of white, gray, or other monochromatic color steel plate specifications, but as a decorative finish of the steel plate 15, the above-mentioned olefin-based, vinyl chloride-based resin-based film is subjected to printing processing. By sticking the sheet to the surfaces 15a and 15b, the range of use of the steel sheet 15 including interior use can be expanded as a panel having design properties.

また、芯材5の側面5d及び凹溝7の内壁面には、鋼製部材12の抜けを防止する目的で、エンボス加工や粗くする加工が施されていてもよい。
また、耐火パネル2の表面或いは表面と裏面との両方、即ち鋼板15の表面15a或いは表面15aと裏面15bとの両方に、化粧シートが貼られていてもよい。このように用いられる化粧シートは、遮熱性を有していることが好ましい。
Further, the side surface 5d of the core material 5 and the inner wall surface of the concave groove 7 may be embossed or roughened for the purpose of preventing the steel member 12 from coming off.
Moreover, the decorative sheet may be affixed on the surface of the fireproof panel 2 or both of the front surface and the back surface, that is, both the front surface 15a of the steel plate 15 or both the front surface 15a and the back surface 15b. The decorative sheet used in this way preferably has a heat shielding property.

また、耐火パネル2,2同士を連結する際に、少なくとも一方の耐火パネル2の一部分に衝撃を吸収可能な部材を貼り付けてもよい。一部分とは、例えば耐火パネル2の側面2d等を示すが、特に限定されず、連結の際に傷付き易い箇所のことである。衝撃を吸収可能な部材(以下、衝撃吸収部材)とは、所謂クッション性を有する部材であって、例えばシーリング材,発泡合成ゴム、発泡スチロール、発泡樹脂(耐火塗料を含む)等が挙げられる。耐火パネル2の一部分に貼り付ける際の衝撃吸収部材の厚みは、耐火パネル2,2同士を連結する際に生じる隙間の幅の100%から200%であることが好ましい。このような構成により、耐火パネル2,2同士を連結する際に、耐火パネル2,2の一部分に互いが当たったりして傷付くのを防止することができる。   Moreover, when connecting the fireproof panels 2 and 2, a member capable of absorbing an impact may be attached to a part of at least one fireproof panel 2. The term “part” refers to, for example, the side surface 2d of the fireproof panel 2, but is not particularly limited, and refers to a portion that is easily damaged when connected. A member capable of absorbing an impact (hereinafter referred to as an impact absorbing member) is a member having a so-called cushioning property, and examples thereof include a sealing material, a foamed synthetic rubber, a polystyrene foam, a foamed resin (including a fireproof paint) and the like. The thickness of the shock absorbing member when pasted on a part of the refractory panel 2 is preferably 100% to 200% of the width of the gap generated when the refractory panels 2 and 2 are connected to each other. With such a configuration, when the fireproof panels 2 and 2 are connected to each other, it is possible to prevent the fireproof panels 2 and 2 from hitting each other and being damaged.

次いで、上述した本発明を適用した一実施形態の耐火パネルの連結構造の効果を裏付けるために行った実施例及び比較例について説明する。なお、本発明は以下の実施例にのみ限定されるものではない。   Next, examples and comparative examples performed to support the effect of the fireproof panel connection structure of the embodiment to which the present invention is applied will be described. In addition, this invention is not limited only to a following example.

図10は、図11(a),(b)のように構成した大規模な耐火間仕切りの試験体において非加熱側から見たときの温度の測定位置を示している。なお、図10では、図11(b)と異なり、芯材の横目地の高さ位置は一致していない。   FIG. 10 shows a temperature measurement position when viewed from the non-heating side in a large-scale fireproof partition test body configured as shown in FIGS. 11 (a) and 11 (b). In FIG. 10, unlike in FIG. 11 (b), the height positions of the horizontal joints of the core material do not match.

また、図13は、図10に示す試験体に対して1時間の加熱を行った際の冷却期間も含めた各測定位置における温度上昇値の変化を示したものである。図13には、耐火基準とされている最高温度上昇値(すなわち、上限値)の180℃と、望ましい最高温度上昇値(すなわち、上限値)の162℃をそれぞれ、実線と破線で示している。
また、図14は、図10に示す試験体に関し、前述の加熱後の冷却期間を含めた各測定位置における温度上昇値の変化の平均値を示したものである。図14には、耐火基準とされている平均温度上昇値の140℃と、望ましい平均温度上昇値の126℃をそれぞれ、実線と破線で示している。
FIG. 13 shows changes in the temperature rise value at each measurement position including the cooling period when the specimen shown in FIG. 10 is heated for 1 hour. In FIG. 13, the maximum temperature rise value (that is, the upper limit value) of 180 ° C., which is the fire resistance standard, and the desired maximum temperature increase value (ie, the upper limit value) of 162 ° C. are indicated by a solid line and a broken line, respectively. .
Moreover, FIG. 14 shows the average value of the change of the temperature rise value at each measurement position including the cooling period after the heating described above with respect to the specimen shown in FIG. In FIG. 14, the average temperature rise value of 140 ° C., which is the fire resistance standard, and the desirable average temperature rise value of 126 ° C. are indicated by a solid line and a broken line, respectively.

図13及び図14に示すように、本発明を適用した試験体における最高温度上昇値は、150℃程度であり、162℃以下を満たしている。特に、間仕切りの大部分を占める面部分では、最高でも80℃程度までしか温度が上昇せず、延焼防止性が高いものとなっていることがわかる。また、発明を適用した試験体における平均温度上昇値は、90℃程度であり、126℃以下も満たしている。   As shown in FIGS. 13 and 14, the maximum temperature rise value in the test body to which the present invention is applied is about 150 ° C. and satisfies 162 ° C. or less. In particular, it can be seen that the surface portion that occupies most of the partition rises only up to about 80 ° C., and has high fire spread prevention properties. Moreover, the average temperature rise value in the test body to which the invention is applied is about 90 ° C. and satisfies 126 ° C. or less.

厚み寸法25mmの珪酸カルシウム板(JIS A 5430のタイプ3,0.2TK)の側面に凹溝を形成し、高さ寸法が15mmの鋼製部材を600mm間隔で凹溝に嵌合した後、表面及び裏面にウレタン系樹脂塗料で鋼板を接着したパネルを用意し、サネ材を用いて、図11(a),(b)に示すように複数枚のパネルを幾何学的に配置することで、小規模な耐火間仕切りを組み立てた。各パネルには、図11(a),(b)の破線で示す所定の位置に縦目地及び横目地を設けた。図11(a)及び図11における数値範囲は、本実施例において各部材の寸法が当該数値範囲内であったことを示している。また、網掛けで示した部分は鋼板を剥ぎ取った状態の珪酸カルシウム板を示している。さらに、一点鎖線は、サネ材によるパネル同士の連結位置を示している。なお、図11(b)に示すように,ここでは,芯材の横目地の高さ位置は一致させている。   A groove is formed on the side of a calcium silicate plate having a thickness of 25 mm (JIS A 5430 type 3, 0.2TK), and a steel member having a height of 15 mm is fitted into the groove at intervals of 600 mm. And by preparing a panel in which the steel plate is bonded to the back surface with urethane resin paint, using a sap material, geometrically arranging a plurality of panels as shown in FIGS. 11 (a) and (b), A small fireproof partition was assembled. Each panel was provided with vertical joints and horizontal joints at predetermined positions indicated by broken lines in FIGS. The numerical ranges in FIG. 11A and FIG. 11 indicate that the dimensions of each member in this example were within the numerical range. Moreover, the part shown with the meshing has shown the calcium-silicate board of the state which peeled off the steel plate. Furthermore, the dashed-dotted line has shown the connection position of the panels by a sap material. In addition, as shown in FIG.11 (b), the height position of the horizontal joint of a core material is made to correspond here.

図11(a)に示すパネルの表面側を火災側と想定し、標準加熱(ISO834)による加熱試験を実施した。図11(a)に示すパネルの裏面側(非火災側)において、図12に示すように高さ方向上部の所定の測定位置aから測定位置gまでと、高さ方向中央部の所定の測定位置hから測定位置nまでと、高さ方向下部の所定の測定位置oから測定位置uまでの合計21の位置で温度を測定した。測定位置aから測定位置gまでの上昇温度の経過時間依存性を図15に示す。測定位置hから測定位置nまでの上昇温度の経過時間依存性を図16に示す。測定位置oから測定位置uまでの上昇温度の経過時間依存性を図17に示す。   Assuming that the surface side of the panel shown in FIG. 11A is a fire side, a heating test by standard heating (ISO834) was performed. On the back side (non-fire side) of the panel shown in FIG. 11 (a), as shown in FIG. 12, from the predetermined measurement position a in the upper part in the height direction to the measurement position g, the predetermined measurement in the central part in the height direction. The temperature was measured at a total of 21 positions from the position h to the measurement position n and from a predetermined measurement position o to the measurement position u in the lower part of the height direction. FIG. 15 shows the elapsed time dependence of the rising temperature from the measurement position a to the measurement position g. FIG. 16 shows the elapsed time dependence of the rising temperature from the measurement position h to the measurement position n. FIG. 17 shows the elapsed time dependence of the rising temperature from the measurement position o to the measurement position u.

パネルの高さ方向上部は、最も温度が高くなることが予想される位置である。図15から図17を見ると、パネルの高さ方向上部(芯材の横目地の高さが一致している部分)且つ幅方向中心の測定位置dでは、経過時間80分をピークとして約60分から約110分の間で、他の測定位置aから測定位置c及び測定位置eから測定位置uにおける温度よりも上昇温度が高くなったが、全体的には、最も温度が高くなることが予想された非加熱側のパネル上部の連結部(即ち、測定位置d等)でも、上昇温度が概ね抑制されていることがわかる。   The upper part in the height direction of the panel is a position where the temperature is expected to be highest. From FIG. 15 to FIG. 17, at the measurement position d at the upper part in the height direction of the panel (the portion where the height of the horizontal joints of the core material coincides) and at the center in the width direction, the elapsed time of 80 minutes is the peak. Between about 110 minutes and about 110 minutes, the rising temperature is higher than the temperature at other measurement positions a to c and from measurement position e to measurement position u, but overall, the temperature is expected to be the highest. It can be seen that the rise in temperature is generally suppressed even at the connection portion (that is, the measurement position d and the like) at the upper portion of the non-heated panel.

以上説明した実施例の標準加熱試験の結果から、本発明を適用した耐火パネルの連結構造は十分な耐火性能及び延焼防止能力を有することを確認した。これにより、提案する耐火パネルの連結構造の有効性を実証した。   From the result of the standard heating test of the embodiment described above, it was confirmed that the connection structure of the fireproof panel to which the present invention was applied has sufficient fireproof performance and fire spread prevention ability. This proved the effectiveness of the proposed fireproof panel connection structure.
