透視性を損なうことがない防火複層ガラスとして、下記特許文献1には、耐熱結晶化ガラス板と、耐熱結晶化ガラス板の片側に間隔おいて且つ耐熱結晶化ガラス板と平行に配設された片側非耐熱ガラス板と、耐熱結晶化ガラス板の他側に間隔おいて且つ耐熱結晶化ガラス板と平行に配設された他側非耐熱ガラス板とを含む防火複層ガラスが開示されている。片側非耐熱ガラス板及び他側非耐熱ガラス板の外面、即ち耐熱結晶化ガラス板と対面しない側面には、非銀系低放射膜が被覆されている。   As a fireproof double-layered glass which does not impair transparency, according to Patent Document 1 below, a heat-resistant crystallized glass plate and a heat-resistant crystallized glass plate are disposed at intervals on one side and in parallel with the heat-resistant crystallized glass plate.

特開2014−97901公報JP, 2014-97901, A 再公表特許WO2014/168219公報Re-issued patent WO2014 / 168219 gazette

而して、上記特許文献1及び2に開示された防火複層ガラスには、適切な部位に適切な反射膜が被覆されておらず、製造コストが高価になるにも拘わらず充分な防火特性が得られない、という問題がある。例えば、上記特許文献1に開示されている防火複層ガラスにおいては、非耐熱ガラス板の外面に非銀系低放射膜を被覆しているが、これらの非銀系低放射膜は、建造物の外側又は内側からの火炎に直接的に晒されると容易に損傷され、低放射膜の機能、即ち熱反射機能、を充分に発揮することができない。従って、製造コストに対して充分な防火特性が得られない。また、上記特許文献2に開示されている防火複層ガラスにおいては、耐熱ガラスの表面に反射膜を被覆しているが、かような反射膜は防火に対して有効に作用しない。   Thus, the fire protection double glass disclosed in the above-mentioned Patent Documents 1 and 2 is not coated with a suitable reflective film on an appropriate site, and sufficient fire protection characteristics despite the fact that the production cost is high. There is a problem that can not be obtained. For example, in the fireproof double-glazing disclosed in Patent Document 1 described above, the outer surface of the non-heat-resistant glass plate is coated with a non-silver-based low emission film, but these non-silver-based low-emission films It is easily damaged if exposed directly to the flame from the outside or inside of the film, and the function of the low radiation film, that is, the heat reflection function can not be sufficiently exerted. Therefore, sufficient fire protection characteristics can not be obtained for the manufacturing cost. Moreover, in the fireproof double-glazing disclosed in Patent Document 2, the surface of the heat-resistant glass is coated with a reflective film, but such a reflective film does not work effectively against fire.

本発明は、上記のとおりの事実に鑑みてなされたものであり、その主たる技術的課題は、適切な部位に適切な反射膜が被覆され、製造コストが必要最小限に抑制されるにも拘わらず充分な防火特性を有する、新規且つ改良された防火複層ガラスを提供することである。   The present invention has been made in view of the above-mentioned facts, and the main technical problem is that the appropriate part is coated with the appropriate reflective film, and the manufacturing cost is minimized. It is an object of the present invention to provide a new and improved fire protection double glazing which has sufficient fire protection properties.

本発明者は、鋭意検討の結果、片側非耐熱ガラス及び他側非耐熱ガラス板の内面、即ち耐熱結晶化ガラス板に対面する面、に銀系低反射膜を被覆することによって、上記主たる技術的課題を達成することができることを見出した。   The inventors of the present invention, as a result of intensive investigations, coated the silver-based low reflection film on the inner surface of one side non-heat resistant glass and the other side non heat resistant glass plate, that is, the surface facing the heat resistant crystallized glass plate. Found that it is possible to achieve the

Preferably, the outer surface of the one side non-heat-resistant glass plate and the outer surface of the other side non-heat-resistant glass plate are not coated. In a preferred embodiment, at least one of the one side non-heat resistant glass plate and the other side non-heat resistant glass plate is a composite crime prevention non heat resistant glass plate in which two non heat resistant glass plates are joined with a crime prevention layer interposed.

以下、本発明に従って構成された防火複層ガラスの好適実施形態を図示している添付図面を参照して、更に詳細に説明する。   The preferred embodiments of the fire protection double glazing constructed in accordance with the present invention will now be described in more detail with reference to the accompanying drawings which illustrate.

図1を参照して説明すると、本発明に従って構成された図示の防火複層ガラスは中央に位置する耐熱ガラス板2と、耐熱ガラス板2の片側(図1において左側であり、建造物の外側)に適宜の間隔をおいて且つ耐熱ガラスス板2と平行に配設された片側非耐熱ガラス板4と、耐熱ガラス板2の他側(図1において右側であり、建造物の内側)に適宜の間隔をおいて且つ耐熱ガラス板2と平行に配設された他側非耐熱ガラス板6とを含んでいる。耐熱ガラス板2は、熱膨張率が著しく小さい或いは実質上零である耐熱結晶化ガラス板であるのが好都合である。好適な耐熱結晶化ガラス板としては、日本電気硝子株式会社から商品名「ファイアライト」として販売されている耐熱結晶化ガラスを挙げることができる。耐熱ガラス板2を構成する耐熱結晶化ガラスは3.0乃至6.0mm程度の厚さであるのが好適である。片側非耐熱ガラス板4及び他側非耐熱ガラス板6は通常のフロートガラス板から構成することができる。片側非耐熱ガラス板4及び他側非耐熱ガラス板6の厚さは3.0乃至5.0mm程度でよい。   Referring to FIG. 1, the illustrated fireproof double glass constructed according to the present invention is a heat resistant glass plate 2 located at the center, and one side of the heat resistant glass plate 2 (on the left side of FIG. And one side of the non-heat-resistant glass plate 4 disposed in parallel with the heat-resistant glass plate 2 and the other side of the heat-resistant glass plate 2 (right side in FIG. 1, inside of the building) And the other non-heat-resistant glass plate 6 disposed parallel to the heat-resistant glass plate 2. The heat-resistant glass plate 2 is advantageously a heat-resistant crystallized glass plate whose coefficient of thermal expansion is extremely small or substantially zero. As a suitable heat-resistant crystallized glass plate, a heat-resistant crystallized glass sold under the trade name "Firelight" by Nippon Electric Glass Co., Ltd. can be mentioned. The heat-resistant crystallized glass constituting the heat-resistant glass plate 2 preferably has a thickness of about 3.0 to 6.0 mm. The one-side non-heat-resistant glass plate 4 and the other-side non-heat-resistant glass plate 6 can be made of ordinary float glass plates. The thickness of one side non-heat-resistant glass plate 4 and the other side non-heat-resistant glass plate 6 may be about 3.0 to 5.0 mm.

耐熱ガラス板2の片側面(図1において左側面)の外周縁部と非耐熱ガラス板4の内面(耐熱ガラス板2に対面する、図1において右側面)の外周縁部との間には、スペーサ部材8が配設されていると共にシール材10及び12が配設されている。更に詳述すると、スペーサ部材8はアルミニウム、ステンレス鋼又は鉄の如き適宜の金属或いはこれらの金属とポリアミド樹脂の如き硬質合成樹脂との複合材料から中空形状に形成されているのが好都合である。かかるスペーサ部材8の両側面にはブチル系或いはポリイソブチレン系でよい一次シール材10が塗布されており、耐熱ガラス板2の片側面の外周縁部と片側非耐熱ガラス板4の内面の外周縁部とは一次シール材10に密着されてスペーサ部材8に接合される。しかる後にスペーサ部材8及び一次シール材10の外周面上にシリコーン系或いはポリサルファイド系でよい二次シール材12が充填され、かくして耐熱ガラス板2と片側非耐熱ガラス4との間の空間14が密封される。耐熱ガラス板2の他側面(図1において右側面)の外周縁部と非耐熱ガラス板6の内面(耐熱ガラス板2に対面する、図1において左側面)の外周縁部との間にも、同様に、スペーサ部材8が配設されていると共にシール材10及び12が配設されている。即ち、スペーサ部材8の両側面上にはブチル系或いはポリイソブチレン系でよい一次シール材10が塗布されており、耐熱ガラス板2の他側面の外周縁部と他側非耐熱ガラス板6の内面の外周縁部とは一次シール材10に密着されてスペーサ部材8に接合される。しかる後にスペーサ部材8及び一次シール材10の外周面上にシリコーン系或いはポリサルファイド系でよい二次シール材12が充填され、かくして耐熱ガラス板2と他側非耐熱ガラス6との間の空間16が密封される。上記のとおりの防火複層ガラスは、塩化ビニルの如き適宜の合成樹脂樹或いはアルミニウムの如き適宜の金属から形成された枠体18に装填されて、防火窓或いは防火扉として建造物に組み込まれる。   Between the outer peripheral edge of one side surface (left side surface in FIG. 1) of the heat resistant glass plate 2 and the outer peripheral edge portion of the inner surface of the non-heat resistant glass plate 4 (facing the heat resistant glass plate 2; right side surface in FIG. 1) The spacer member 8 is disposed, and the sealing materials 10 and 12 are disposed. More specifically, the spacer member 8 is advantageously formed in a hollow shape from a suitable metal such as aluminum, stainless steel or iron or a composite material of these metals and a hard synthetic resin such as a polyamide resin. The primary sealing material 10 which may be butyl or polyisobutylene is applied to both side surfaces of the spacer member 8, and the outer peripheral edge of one side surface of the heat resistant glass plate 2 and the outer peripheral edge of the inner surface of the one side non heat resistant glass plate 4. The part is in close contact with the primary seal member 10 and joined to the spacer member 8. Thereafter, the outer peripheral surface of the spacer member 8 and the primary sealing material 10 is filled with the secondary sealing material 12 which may be silicone or polysulfide, thus sealing the space 14 between the heat resistant glass plate 2 and the one side non-heat resistant glass 4 Be done. Also between the outer peripheral edge of the other side (right side in FIG. 1) of the heat resistant glass plate 2 and the outer peripheral edge of the inner surface (facing the heat resistant glass plate 2, left side in FIG. 1) of the non-heat resistant glass plate 6 Similarly, the spacer member 8 is disposed, and the sealing materials 10 and 12 are disposed. That is, the primary sealing material 10 which may be butyl or polyisobutylene is applied on both side surfaces of the spacer member 8, and the outer peripheral edge of the other side surface of the heat resistant glass plate 2 and the inner surface of the other side non heat resistant glass plate 6. The outer peripheral edge portion is closely attached to the primary seal member 10 and joined to the spacer member 8. Thereafter, the outer peripheral surface of the spacer member 8 and the primary sealing material 10 is filled with the secondary sealing material 12 which may be silicone or polysulfide, thus the space 16 between the heat resistant glass plate 2 and the other side non heat resistant glass 6 Be sealed. The fireproof double glazing as described above is loaded into a frame 18 made of a suitable synthetic resin such as vinyl chloride or a suitable metal such as aluminum, and is incorporated into a building as a fire window or fire door.

本発明に従って構成された防火複層ガラスにおいては、片側非耐熱ガラス板4の、耐熱ガラス板2に対面する内面(図1において右側面)及び他側非耐熱ガラス板6の、耐熱ガラス板2に対面する内面(図1において左側面)に、銀系低放射膜20が被覆されていることが重要である。図1に図示する実施形態においては、片側非耐熱ガラス板4の内面及び他側非耐熱ガラス板6の内面における、スペーサ部材8、一次シール材10及び二次シール材12が配設されている外周縁部には銀系低放射膜が被覆されていないが、外周縁部以外の全領域に渡って銀系低放射膜20が被覆されている。非銀系低放射膜、例えば酸化スズ(SnO)膜を被覆することも意図され得るが、非銀系低放射膜は銀系放射膜20に比べて放射率が大きい故に、本発明においては効果的な防火のためには放射率が充分に小さい銀系放射膜20を被覆することが重要である。一方、銀系低放射膜20は非銀系低放射膜に比べて物理的特性が劣り損傷され易いが、片側非耐熱ガラス板4及び他側非耐熱ガラス板6の外面ではなく内面に被覆される故に、物理的特性が劣ることによって問題が発生することはない。 In the fireproof double glass constructed according to the present invention, the heat resistant glass plate 2 of the inner surface (right side surface in FIG. 1) of the one side non heat resistant glass plate 4 facing the heat resistant glass plate 2 and the other side heat resistant glass plate 6 It is important that the silver-based low-emission film 20 be coated on the inner surface facing the (left side in FIG. 1). In the embodiment illustrated in FIG. 1, the spacer member 8, the primary seal material 10 and the secondary seal material 12 are disposed on the inner surface of the one side non-heat resistant glass plate 4 and the inner surface of the other side non heat resistant glass plate 6. The outer peripheral portion is not coated with the silver-based low emission film, but the silver-based low emission film 20 is coated over the entire area other than the outer peripheral portion. Although coating of a non-silver-based low emission film such as a tin oxide (SnO 2 ) film may also be intended, the non-silver-based low-emission film has a higher emissivity than the silver-based emission film 20. It is important to coat a silver-based radiation film 20 with a sufficiently low emissivity for effective fire protection. On the other hand, silver-based low-emission film 20 is inferior in physical properties to non-silver-based low-emission film and is liable to be damaged, but it is coated on the inner surface of one side non-heat resistant glass plate 4 and other side non heat resistant glass plate 6 Therefore, problems are not caused by inferior physical properties.

片側非耐熱ガラス板4及び他側非耐熱ガラス板6の外面には、製造コストの増大を避けるため、低放射膜等の被覆を施さないのが好ましい。片側非耐熱ガラス板4及び他側非耐熱ガラス板6の外面に低放射膜を被覆したとしても、後の説明からも理解される如く、防火特性が効果的に向上されることはない。同様に、耐熱ガラス板2の両表面にも低放射膜等の被覆を施さないのが望ましい。   In order to avoid an increase in manufacturing cost, it is preferable not to apply a coating such as a low radiation film to the outer surfaces of the one side non-heat resistant glass plate 4 and the other side non heat resistant glass plate 6. Even if the low radiation film is coated on the outer surface of the one-side non-heat-resistant glass plate 4 and the other-side non-heat-resistant glass plate 6, as will be understood from the following description, the fire resistance characteristics are not effectively improved. Similarly, it is desirable not to apply a coating such as a low radiation film to both surfaces of the heat resistant glass plate 2.

本発明に従って構成された上述したとおりの防火複層ガラスにおいては、建造物の外側からの火炎に対しては、火炎が直接的に作用する片側非耐熱ガラス板4は損傷されてしまう(本発明者等の経験によれば、上記特許文献1に開示されている如く片側非耐熱ガラス板4の外面に低放射膜が被覆されていたとしても、直接的に作用する火炎によって片側非耐熱ガラス板4は損傷されてしまう)が、耐熱ガラス2は損傷されることなく維持される。そして、火炎に起因する高温は、密封されている空間16による断熱作用と共に、耐熱ガラス板2によって防護されている他側非耐熱ガラス板6の内面に被覆されている銀系低放射膜20に反射作用によって、建造物内への伝導が効果的に遮断される。同様に、建造物の内側からの火炎に対しては、火炎が直接的に作用する他側非耐熱ガラス板6は損傷されてしまうが、耐熱ガラス2は損傷されることなく維持される。そして、火炎に起因する高温は、密封されている空間14の断熱作用と共に、耐熱ガラス板2によって防護されている片側ガラス板4の内面に被覆されている銀系低放射膜20に反射作用によって、建造物内への伝導が効果的に遮断される。   In the fireproof double glazing as described above constructed according to the present invention, one side non-heat resistant glass plate 4 to which the flame directly acts is damaged with respect to the flame from the outside of the building (this invention According to the experience of the inventors, even if the low radiation film is coated on the outer surface of the one side non-heat resistant glass plate 4 as disclosed in the above-mentioned Patent Document 1, the one side non heat resistant glass plate is directly affected by the flame. 4 is damaged), but the heat resistant glass 2 is maintained without being damaged. The high temperature caused by the flame is, together with the heat insulating function by the sealed space 16, to the silver-based low-emission film 20 coated on the inner surface of the other non-heat-resistant glass plate 6 protected by the heat-resistant glass plate 2. The reflection action effectively blocks conduction into the structure. Similarly, for the flame from the inside of the building, the other side non-heat resistant glass plate 6 directly affected by the flame is damaged, but the heat resistant glass 2 is maintained without being damaged. The high temperature caused by the flame is reflected by the silver-based low-emission film 20 coated on the inner surface of the one-side glass plate 4 protected by the heat-resistant glass plate 2 together with the heat insulating action of the sealed space 14. The conduction into the building is effectively cut off.

図2には、本発明に従って構成された防火複層ガラスの他の好適実施形態が図示されている。図2に図示する防火複層ガラスにおいては、他側非耐熱ガラス板6は、防犯層6aを介在せしめて2枚の非耐熱ガラス板6b及び6cを接合することによって形成された複合防犯非耐熱ガラス板から構成されている。防犯層6aはポリビニルブチラール膜或いはポリカーボネート板から形成することができ、非耐熱ガラス板6b及び6cは通常のフロートガラス板でよい。防犯層6aは0.8乃至2.3mm程度の厚さを有し、ガラス板6b及び6cの各々は2.0乃至5.0mm程度の厚さを有し、他側非耐熱ガラス板6の厚さは4.8乃至12.3mm程度であるのが好都合である。所望ならば、他側非耐熱ガラス板6を複合防犯非耐熱ガラス板から構成することに代えて或いはこれに加えて片側非耐熱ガラス板4を複合防犯非耐熱ガラス板から構成することもできる。片側非耐熱ガラス板4と他側非耐熱ガラス板6との少なくとも一方が複合防犯非耐熱ガラス板から構成されている場合、防火複層ガラスは防火特性に加えて防犯特性(ドライバー或いはバール等を使用した破損に対する高い抵抗力)を備える。図2に図示する防火複層ガラスの上述した点以外の構成は、図1に図示する防火複層ガラスと実質上同一である。   FIG. 2 illustrates another preferred embodiment of a fire protection double glazing constructed in accordance with the present invention. In the fire prevention double glazing illustrated in FIG. 2, the other side non heat resistant glass plate 6 is a composite crime prevention non heat resistant formed by joining two non heat resistant glass plates 6 b and 6 c with the crime prevention layer 6 a interposed. It consists of a glass plate. The crime prevention layer 6a can be formed of a polyvinyl butyral film or a polycarbonate plate, and the non-heat-resistant glass plates 6b and 6c may be ordinary float glass plates. The crime prevention layer 6a has a thickness of about 0.8 to 2.3 mm, and each of the glass plates 6b and 6c has a thickness of about 2.0 to 5.0 mm. The thickness is conveniently in the order of 4.8 to 12.3 mm. If desired, the other side non-heat resistant glass plate 6 may be made of a composite crime prevention non-heat resistant glass plate instead of or in addition to the composite non-heat resistant glass plate 6. When at least one of the one-sided non-heat-resistant glass plate 4 and the other-side non-heat-resistant glass plate 6 is composed of a composite crime prevention non-heat-resistant glass plate, the fireproof double glazing has crime prevention characteristics (driver or bar etc. Equipped with high resistance to breakage). The configuration other than the above-described point of the fire protection double glass illustrated in FIG. 2 is substantially the same as the fire protection double glass illustrated in FIG.
