Description

[Technical field]

[0001] The present invention relates to a glass module, a glass unit and a glass window comprising glass sheets. [Background technology]

[0002] Patent Document 1 discloses a double-glazing unit in which the periphery of the glass plate is covered with a flame-shielding member such as a frame. The glass plate of the double-glazing unit is composed of heat-resistant glass and low-E glass, and if a fire occurs on the heat-resistant glass side, the center of the heat-resistant glass will be directly exposed to the combustion heat. Therefore, the heat-resistant glass becomes hotter at the center and coldest at the edge, and is prone to thermal cracking due to the temperature difference between the center and the edge.

[0003] Therefore, the glass unit shown in Patent Document 1 is equipped with a heat-conducting member whose end portion contacts the frame while being in surface contact with the edge surface of the heat-resistant glass in order to reduce the temperature difference between the center and edge surface of the heat-resistant glass. With this configuration, heat is transferred from the frame, which has become hot due to a fire, to the edge surface of the heat-resistant glass via the heat-conducting member. This causes the temperature of the edge surface of the heat-resistant glass to rise, which results in reducing the temperature difference between the center and edge surface of the heat-resistant glass, and prevents thermal cracking.

[0004] [Patent Document 1] JP 2011-220029 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the double-glazing unit of Patent Document 1, the heat-conducting member is provided across the edge surface of the heat-resistant glass and the frame. In other words, the temperature rise of the edge surface inevitably requires the temperature rise of the frame, and if the frame is not directly exposed to flames, the temperature rise of the edge surface is slow, and it is still prone to thermal cracking. In addition, since the end of the heat-conducting member is in contact with the frame, if the dimensional accuracy of the heat-conducting member in the direction perpendicular to the plate surface between the heat-resistant glass and the frame is poor, the contact between the end of the heat-conducting member and the frame becomes insufficient, making it difficult to conduct heat to the edge surface. Therefore, it was necessary to improve the dimensional accuracy of the heat-conducting member in the direction perpendicular to the plate surface between the heat-resistant glass and the frame. Furthermore, if the frame is made of a material with low thermal conductivity, the end surface of the heat-resistant glass cannot be expected to rise in temperature sufficiently even through the heat-conducting member, so there was room for improvement in this respect as well.

[0006] In view of the above circumstances, there is a demand for a glass module, a glass unit, and a glass window that can efficiently prevent thermal cracking of glass sheets in the event of a fire. [Means for solving the problem]

[0007] A characteristic configuration of a glass module according to the present invention is a glass module that faces a flame-shielding member and can be assembled to the flame-shielding member, comprising a glass plate having a first outer panel surface and a second outer panel surface provided on the rear side of the first outer panel surface, and a heat conductive member arranged adjacent to the first outer panel surface and the second outer panel surface, wherein the glass plate has a flame-shielding area on its plate surface that can be covered by the flame-shielding member, and the heat conductive member has a higher thermal conductivity than the glass plate and is configured to be arranged in at least a portion of the flame-shielding area.

[0008] In the event of a fire occurring in a compartment facing one of the glass sheets, the non-flame-shielding area that is not covered by the flame-shielding member is directly exposed to the flame, while the flame-shielding area is not directly exposed to the flame due to the flame-shielding member. As a result, the non-flame-shielding area becomes hotter and colder, generating thermal stress in the flame-shielding area that restricts the thermal expansion of the non-flame-shielding area, which may cause thermal cracking of the glass sheet.

[0009] Therefore, the glass module of the present configuration includes a heat-conducting member disposed adjacent to the first and second outer plate surfaces of the glass plate, and the heat-conducting member has a higher thermal conductivity than the glass plate and is configured to be disposed in at least a part of the flame-shielding region. Therefore, heat is quickly conducted from the non-flame-shielding region to the flame-shielding region in the glass plate. As a result, when a fire breaks out in the compartment area, the heat of combustion is conducted to the non-flame-shielding region of the glass plate exposed to the compartment area, and is also conducted from the non-flame-shielding region to the flame-shielding region of the glass plate via the heat-conducting member. As a result, the temperature of the flame-shielding region rises and the temperature difference between the non-flame-shielding region and the flame-shielding region becomes smaller, so that the thermal cracking phenomenon of the glass plate can be prevented from occurring. In addition, since the heat-conducting member only needs to be disposed adjacent to the first and second outer plate surfaces of the glass plate, dimensional accuracy in a direction perpendicular to the plate surface of the glass plate is not required. Therefore, the thickness of the heat-conducting member can be easily adjusted within a dimensional range equal to or smaller than the gap between the glass plate and the flame-shielding member, taking into account the specifications of the glass plate and the thermal conductivity of the heat-conducting member. In this way, the glass module having the present configuration can effectively prevent thermal cracking of the glass sheets in the event of a fire.

[0010] Another characteristic configuration is that the flame-blocking area is provided on the plate surface of the peripheral edge portion of the glass plate, and is 10 mm to 30 mm from the end face of the glass plate.

[0011] According to this configuration, since the flame-shielding area is provided on the plate surface of the peripheral portion of the glass plate, the glass plate can conduct heat from the center to the peripheral portion via the heat-conducting member. As a result, the glass plate is less likely to crack due to heat. In addition, the overlap (insertion amount) of the glass plate with respect to the flame-shielding member is stipulated to be 10 mm or more in the "Japan Architectural Standard Specifications for Construction Work and Commentary JASS17 Glass Work" (hereinafter referred to as JASS17). On the other hand, if the vertical length of the flame-shielding area exceeds 30 mm, the flame-shielding member inhibits heating of the peripheral portion of the glass plate, and the temperature difference between the center and the peripheral portion of the glass plate becomes large, which makes the glass plate more likely to crack due to heat. Therefore, the flame-shielding area of ​​this configuration is configured to be 10 mm or more and 30 mm or less from the edge of the glass plate.

[0012] Another characteristic feature is that the heat conducting member is disposed on at least a part of the edge surface of the glass plate.

[0013] According to this configuration, the heat conductive member is disposed on at least a part of the edge surface as well as on the plate surface of the peripheral portion of the glass plate, so that the heat of the center portion of the glass plate that is directly exposed to the flame is efficiently transferred to the edge surface of the glass plate by the heat conductive member. As a result, the temperature of the edge surface of the glass plate is easily increased, so that the temperature difference between the center and the edge portion of the glass plate can be reduced. Therefore, it is possible to reliably prevent thermal cracking of the glass plate at the edge portion of the glass plate, which is far from the center and where the temperature increase is slow.

[0014] Another characteristic feature is that the heat conductive member is disposed only in the flame blocking area.

[0015] According to this configuration, the heat conductive member is disposed only in the flame-shielding area, and therefore the heat conductive member is disposed on the glass sheet in a state in which it is not visible from the outside. This makes it possible to prevent thermal cracking of the glass sheet without the heat conductive member affecting the appearance of the glass sheet.

[0016] Another characteristic configuration is that the glass plate further has a non-flame-blocking area adjacent to the flame-blocking area and not covered by the flame-blocking member, and the heat conduction member is configured to be able to be arranged on at least one of the first outer panel surface and the second outer panel surface in the non-flame-blocking area.

[0017] According to this configuration, since the heat conductive member is also disposed in the non-flame shielding region, the combustion heat received by the non-flame shielding region of the glass sheet is easily transferred to the flame shielding region via the heat conductive member. This makes it possible to quickly reduce the temperature difference between the non-flame shielding region and the flame shielding region of the glass sheet. In addition, by disposing the heat conductive member in a portion of the non-flame shielding region adjacent to the flame shielding region, it is possible to reduce the range of the heat conductive member in the non-flame shielding region and minimize the effect of the heat conductive member on the appearance of the glass sheet.

[0018] Another characteristic feature is that the heat conducting member is configured so that at least a portion thereof can come into contact with the flame blocking member.

[0019] According to this configuration, the heat conductive member transfers the combustion heat received by the flame-shielding member to the flame-shielding region of the glass plate, so that in the event of a fire, the heat of the flame-shielding member as well as the heat of the non-flame-shielding region of the glass plate is transferred to the flame-shielding region of the glass plate via the heat conductive member, thereby making it possible to more quickly reduce the temperature difference between the non-flame-shielding region and the flame-shielding region of the glass plate.

[0020] Another characteristic feature is that the heat conductive member is configured not to come into contact with the flame blocking member.

[0021] According to this configuration, since the heat conductive member does not come into contact with the flame-shielding member, dimensional accuracy in the direction perpendicular to the surface of the glass plate is not required. Therefore, the thickness of the heat conductive member can be easily adjusted within a dimensional range equal to or smaller than the gap between the glass plate and the flame-shielding member, taking into account the specifications of the glass plate and the thermal conductivity of the heat conductive member.

[0022] Another characteristic feature is that the heat conductive member has a higher absorptivity of near-infrared rays than the glass plate.

[0023] When the flame-shielding member is heated during a fire, the radiant heat generated from the flame-shielding member is propagated by near-infrared rays. However, because the glass plate transmits near-infrared rays, the radiant heat from the flame-shielding member is unlikely to cause a temperature rise in the flame-shielding region of the glass plate. Therefore, the heat-conducting member in this configuration has a higher near-infrared absorption rate than the glass plate. This makes it easier for the flame-shielding region of the glass plate to receive the radiant heat from the flame-shielding member through the heat-conducting member, so that the temperature difference between the non-flame-shielding region and the flame-shielding region of the glass plate can be reduced more quickly.

[0024] Another characteristic feature is that the heat conducting member has an emissivity of 0.1 or more.

[0025] In this configuration, when the emissivity of the thermally conductive member is 0.1 or more, heat loss caused by the radiant heat from the flame-shielding member being reflected by the thermally conductive member is suppressed, and the radiant heat can be efficiently transmitted to the flame-shielding area via the thermally conductive member.

[0026] Another characteristic feature is that the heat conductive member includes a metal foil and an adhesive layer, and the adhesive layer includes an adhesive and thermally conductive fine particles.

[0027] According to this configuration, since the heat conductive member has an adhesive layer having an adhesive, the heat conductive member can be easily fixed to the glass plate. Also, since the heat conductive member has a metal foil and the adhesive layer has heat conductive fine particles, the heat conductive member can reliably transfer heat from the non-flame shielding area of ​​the glass plate to the flame shielding area.

[0028] Another characteristic feature is that the thermal conductivity of the metal foil is 50 W / mK or more.

[0029] For example, the thermal conductivity of a glass plate made of soda glass is generally less than 1 W / mK. In contrast, when the thermal conductivity of the metal foil is 50 W / mK or more as in the present configuration, the heat transfer speed of the heat conductive member is significantly improved compared to the glass plate. This makes it possible for the heat conductive member to quickly transfer the heat of combustion from the non-flame-shielding area of ​​the glass plate to the flame-shielding area, thereby reducing the temperature difference between the non-flame-shielding area and the flame-shielding area of ​​the glass plate.

[0030] Another characteristic feature is that the thermally conductive fine particles have a higher thermal conductivity than the adhesive.

[0031] The adhesive layer of the thermally conductive member tends to have a lower thermal conductivity than the metal foil because of the adhesive. However, by making the thermal conductivity of the thermally conductive fine particles higher than that of the adhesive as in the present configuration, the thermal conductivity of the adhesive layer in the thermally conductive member can be effectively increased.

[0032] Another characteristic feature of the present invention is that the adhesive layer contains the thermally conductive fine particles in an amount of 50% by weight or more and 90% by weight or less.

[0033] As in this configuration, when the content of the thermally conductive fine particles in the adhesive layer is 50% by weight or more and 90% by weight or less, the thermally conductive member can ensure both thermal conductivity and adhesiveness in the adhesive layer. When the content of the thermally conductive fine particles in the adhesive layer is less than 50% by weight, the adhesive layer cannot obtain sufficient thermal conductivity. Also, when the content of the thermally conductive fine particles in the adhesive layer is more than 90% by weight, the proportion of the adhesive is too low, so that the adhesive strength is reduced and the thermally conductive member is easily peeled off from the glass plate.

[0034] Another characteristic feature is that the adhesive layer has a thickness of 10 μm or more and 100 μm or less.

[0035] As in this configuration, when the thickness of the adhesive layer is 10 μm or more and 100 μm or less, the thermal conductive member can ensure both thermal conductivity and adhesiveness in the adhesive layer. In the thermal conductive member, when the thickness of the adhesive layer is less than 10 μm, peeling may occur due to the difference in thermal expansion between the metal foil and the glass plate in the event of a fire. On the other hand, when the thickness of the adhesive layer is more than 100 μm, the adhesive may have a large effect, and the thermal conductivity of the thermal conductive member including the adhesive layer may be reduced.

[0036] Another characteristic feature is that the thermally conductive fine particles have a particle size of 10 μm or more and 100 μm or less.

[0037] As in this configuration, when the particle diameter of the thermally conductive fine particles is 10 μm or more and 100 μm or less, the thermally conductive member can reliably ensure thermal conductivity in the adhesive layer. When the particle diameter of the thermally conductive fine particles is less than 10 μm, the thermally conductive fine particles are unevenly arranged in the adhesive layer, so that uniform thermal conductivity may not be ensured. On the other hand, when the particle diameter of the thermally conductive fine particles is more than 100 μm, the surface area of ​​the thermally conductive fine particles is small, so that the thermal conductivity of the thermally conductive member may be reduced.

[0038] Another characteristic feature is that the thermally conductive fine particles are metal fine particles.

[0039] When the thermally conductive fine particles are metal fine particles as in this configuration, thermal conductivity can be reliably imparted to the adhesive layer.

[0040] A glazing unit according to the present invention is characterized in that it comprises a glazing module having the above-mentioned configuration, and a flame-shielding member that holds the peripheral edge of the glass plate therebetween.

[0041] In the glass unit of this configuration, a glass plate on which a heat-conducting member having a higher thermal conductivity than the glass plate is disposed is sandwiched between flame-shielding members. As a result, if a fire occurs in a compartment facing one of the glass plates, the combustion heat is transferred to a non-flame-shielding region of the glass plate exposed to the compartment, and from the non-flame-shielding region to the peripheral portion of the glass plate via the heat-conducting member of the flame-shielding region. As a result, the temperature of the peripheral portion rises and the temperature difference between the center and peripheral portions of the glass plate becomes smaller, making it difficult for the glass plate to thermally crack.

[0042] Another characteristic feature is that the flame blocking member is configured to clamp the glass plate with its surfaces.

[0043] According to this configuration, the flame-shielding member holds the glass plate between its surfaces, so that the glass plate can be stably held.

[0044] Another characteristic feature is that the flame blocking member is a fixed frame of the sash.

[0045] According to this configuration, since the flame blocking member is a fixed frame of the sash, the flame blocking member is not lost in the event of a fire, and the peripheral portion of the glass plate can be efficiently heated.

[0046] Another characteristic feature is that the thermal conductivity of the fixing frame is not less than 20 W / mK and not more than 250 W / mK.

[0047] In this configuration, by setting the thermal conductivity of the fixing frame to be high, heat is easily transferred from the fixing frame to the peripheral portion of the glass plate. This makes it possible to reduce the temperature difference between the center and the peripheral portion of the glass plate. If the thermal conductivity of the fixing frame is set to be more than 250 W / mK, the fixing frame will be expensive, so the thermal conductivity of the fixing frame in this configuration is set to be 20 W / mK or more and 250 W / mK or less.

[0048] A characteristic configuration of the glass window according to the present invention is that the glass module having the above-mentioned configuration is clamped and fixed between the flame blocking members.

[0049] According to this configuration, the glass module is clamped and fixed between the flame-blocking members, so that thermal cracking of the glass plate can be prevented and fire-retardant performance can be stably maintained. [Brief description of the drawings]

[0051] [First embodiment] A first embodiment of a glass unit 100 according to the present invention will be described with reference to Fig. 1 to Fig. 4. Fig. 2 shows the completed glass unit 100, and Fig. 3 shows the glass unit 100 in a state before assembly. The glass unit 100 comprises a glass module 10 and a flame-shielding member 20. The glass module 10 comprises a glass plate 1 and a heat-conducting member 11 described below.

[0052] As shown in Figures 1 and 2, the glass plate 1 is a rectangular single-layer glass having peripheral edges 8 on all four sides, and is fitted and fixed into a flame-shielding member 20 having a recess along the peripheral edge 8 of the single-layer glass.

[0053] The flame shielding member 20 is composed of a frame 21. The glass plate 1 faces the flame shielding member 20 and is configured to be assembled to the flame shielding member 20. In this embodiment, the frame 21 is a fixed frame of a sash having a recess. The thermal conductivity of the frame 21 is 20 W / mK or more and 250 W / mK or less. The glass plate 1 is fixed in the recess of the frame 21 by having the peripheral portion 8 sandwiched between a backup material 23 and an elastic support 24. A setting block 22 having a function of protecting the end surface 4 of the glass plate 1 is installed on the bottom surface of the recess of the frame 21 into which the four sides of the glass plate 1 are fitted. The setting block 22 only needs to be installed at several points on the lower end of the glass plate 1 to a degree that the weight of the glass plate 1 can be sufficiently distributed and supported, and does not need to be installed over the entire area of ​​the four sides of the glass plate 1. In addition, a backup material 23 is provided between the glass plate 1 and the frame 21 to fix the glass plate 1 to the frame 21. Furthermore, in order to improve waterproofing between the glass plate 1 and the frame 21, an elastic support 24 serving as a sealant is provided on the upper part of the backup material 23. In this way, the glass plate 1 is configured to be able to be clamped by the frame 21 (flame-blocking member 20) via the elastic support 24. This allows the glass plate 1 to be supported in a state in which the gap between the glass plate 1 and the frame 21 (flame-blocking member 20) is filled by the elastic support 24.

[0054] The glass plate 1 has a first outer plate surface 5 and a second outer plate surface 6 provided on the back side of the first outer plate surface 5, and is composed of a single-layer tempered glass having a compressive stress of 150 MPa or more. The glass plate 1 has a flame-shielding area 2 that can be covered by a frame body 21 and a non-flame-shielding area 3 that is visible from the outside and is not covered by the flame-shielding member 20 on the outer plate surfaces 5 and 6. As shown in FIG. 1, the glass plate 1 is configured in a rectangular shape, and the flame-shielding area 2 is provided on the peripheral portion 8 of each of the four sides. Here, the flame-shielding area 2 means a plate surface of the first outer plate surface 5 or the second outer plate surface 6 where the flame is blocked by the frame body 21 when the first outer plate surface 5 or the second outer plate surface 6 of the glass plate 1 is exposed to a flame from a direction perpendicular to the plate surface. That is, the flame-shielding area 2 is an area orthogonally projected from the flame-shielding member 20 onto the glass plate 1. The flame-shielding area 2 is preferably 10 mm or more and 30 mm or less from the end surface 4 of the glass plate 1. JASS17 specifies that the overlap (insertion amount) of the glass plate 1 with respect to the flame-shielding member 20 should be 10 mm or more. On the other hand, if the vertical length of the flame-shielding region 2 exceeds 30 mm, the flame-shielding member 20 inhibits heating of the peripheral portion 8 of the glass plate 1, and the glass plate 1 is more likely to be thermally cracked due to the large temperature difference between the central portion 7 and the peripheral portion 8 of the glass plate 1. In addition, if the glass plate 1 is the above-mentioned tempered glass, it is easier to suppress thermal cracking of the glass plate 1 caused by the temperature difference between the central portion 7 and the peripheral portion 8 of the glass plate 1. Furthermore, as shown in FIG. 2, the end surface 4 of the glass plate 1 is polished into a curved shape to be smooth in order to reduce the risk of breakage during transportation or assembly.

[0055] The glass plate 1 includes a heat conductive member 11 disposed adjacent to the first outer plate surface 5 and the second outer plate surface 6 (flame shielding region 2) of the peripheral portion 8. The heat conductive member 11 has a higher thermal conductivity than the glass plate 1 and is configured to be disposed in at least a part of the flame shielding region 2. That is, the heat conductive member 11 may be disposed in the entire flame shielding region 2 or in a part of the flame shielding region 2. In the example of FIG. 2, the heat conductive member 11 is disposed in the entire flame shielding region 2. In this embodiment, the heat conductive member 11 is formed in a sheet shape and is fixed in a state of surface contact with the outer plate surfaces 5 and 6 of the flame shielding region 2. Here, the surface contact state means that the heat conductive member 11 faces the outer plate surfaces 5 and 6 of the flame shielding region 2, and as long as the majority (for example, 80% or more of the area) of the heat conductive member 11 is in contact with the outer plate surfaces 5 and 6 of the flame shielding region 2, a part of the heat conductive member 11 may be in a non-contact state. The thermal conductivity of the glass plate 1 made of soda glass is generally less than 1 W / mK. On the other hand, the thermal conductivity of the heat conductive member 11 is preferably 50 W / mK or more. For example, a metal or alloy such as Sn, Al, Ag, Cu, or Zn can be used as the heat conductive member 11. The thermal conductivity of Sn is 64 W / mK, the thermal conductivity of Al is 204 W / mK, the thermal conductivity of Ag is 418 W / mK, the thermal conductivity of Cu is 372 W / mK, and the thermal conductivity of Zn is 113 W / mK.

[0056] In this manner, by disposing the heat conductive member 11 adjacent to the outer plate surfaces 5, 6 (flame shielding region 2) of the peripheral portion 8, heat is quickly conducted from the non-flame shielding region 3 to the flame shielding region 2 in the glass plate 1. As a result, for example, if a fire breaks out in a compartmented area facing one of the glass plates 1, the combustion heat is conducted to the non-flame shielding region 3 of the glass plate 1 exposed to the compartmented area, and is also conducted from the non-flame shielding region 3 to the flame shielding region 2 of the glass plate 1 via the heat conductive member 11. As a result, the temperature of the flame shielding region 2 rises and the temperature difference between the non-flame shielding region 3 and the flame shielding region 2 becomes smaller, making it possible to make the glass plate 1 less susceptible to thermal cracking.

[0057] The heat conductive member 11 in this embodiment is provided from the outer plate surfaces 5, 6 to the edge surface 4 of the glass plate 1. The heat conductive member 11 is disposed on at least a part of the edge surface 4 of the glass plate 1. That is, the heat conductive member 11 may be disposed on the entire edge surface 4 of the glass plate 1, or may be disposed on a part of the edge surface 4. In the example of FIG. 2, the heat conductive member 11 is disposed on the entire edge surface 4 of the glass plate 1. As a result, the heat of the center portion 7 of the glass plate 1, which is directly exposed to the flame in the event of a fire, is efficiently transferred to the edge surface 4 of the peripheral portion 8 by the heat conductive member 11. As a result, the temperature of the edge surface 4 of the glass plate 1 is easily increased, so that the temperature difference between the center portion 7 and the peripheral portion 8 of the glass plate 1 can be further reduced. Therefore, in the glass plate 1, it is possible to reliably prevent thermal cracking in the peripheral portion 8 of the glass plate 1, which is far from the center portion 7 and where the temperature rise is slow.

[0058] Of the flame-shielding region 2 and non-flame-shielding region 3 of the glass plate 1, the heat-conducting member 11 is disposed only in the flame-shielding region 2. In other words, the heat-conducting member 11 does not protrude into the non-flame-shielding region 3, and is disposed on the glass plate 1 in a state in which it is not visible from the outside. This makes it possible to prevent thermal cracking of the glass plate 1 without the heat-conducting member 11 affecting the appearance of the glass plate 1.

[0059] In this embodiment, the heat conductive member 11 is disposed over the entire flame-shielding region 2 covered by the flame-shielding member 20 (the height is from the end face 4 to the upper end face of the flame-shielding member 20). With this configuration, in the event of a fire, heat is transferred from the central portion 7 (non-flame-shielding region 3) of the glass plate 1, which has become hot due to the combustion heat of the fire, to the peripheral portion 8 (flame-shielding region 2) via the heat conductive member 11. As a result, the temperature of the peripheral portion 8 of the glass plate 1, which is not directly exposed to the flame due to the flame-shielding member 20, rises quickly, and the temperature difference between the central portion 7 and the peripheral portion 8, which become very hot due to the combustion heat of the fire, is reduced, thereby preventing thermal cracking of the glass plate 1 and improving the fire resistance of the glass plate 1.

[0060] As shown in FIG. 4, the thermal conductive member 11 is, for example, a tape body having excellent thermal conductivity, and includes a metal foil 12 and an adhesive layer 13. The adhesive layer 13 includes an adhesive 14 and thermally conductive fine particles 15. When the thermal conductive member 11 is a tape body, it is easy to make the surface of the thermal conductive member 11 adhere to the glass plate 1, so that improvement in thermal conductivity can be expected. Also, as shown in the glass module 10 of FIG. 3, if the glass plate 1 is prepared in a state in which the thermal conductive member 11 is attached to the outer plate surfaces 5, 6 and the end surface 4 of the peripheral portion 8 of the glass plate 1, the attachment of the thermal conductive member 11 is easy, and the thermal conductive member 11 also protects the end surface 4, which is preferable. That is, as shown in FIG. 3, the glass module 10 in which the thermal conductive member 11 is fixed to the glass plate 1 is inserted into the frame body 21 in which the setting block 22 and the backup material 23 are housed, and the elastic support body 24 is fitted into the gap between the glass module 10 and the frame body 21 to complete the glass unit 100, so that assembly is easy. The thermally conductive member 11 may be provided only in those parts of the glass plate 1 where thermal cracking is likely to occur. However, to ensure fire resistance, it is desirable to provide the thermally conductive member 11 around the entire periphery of the glass plate 1 (the peripheral edges 8 on all four sides).

[0061] In this embodiment, the heat conductive member 11 is configured not to come into contact with the frame 21 of the flame shielding member 20. Since the heat conductive member 11 does not come into contact with the frame 21, the heat conductive member 11 is not required to have dimensional accuracy in the direction perpendicular to the plate surface of the glass plate 1. Therefore, the thickness and the like of the heat conductive member 11 can be easily adjusted within a dimensional range equal to or smaller than the gap between the glass plate 1 and the frame 21, taking into consideration the specifications of the glass plate 1 and the thermal conductivity of the heat conductive member 11.

[0062] The heat conductive member 11 preferably has a higher absorptivity for near infrared rays (wavelength 0.7 μm to 2.5 μm) than the glass plate 1, and particularly preferably has a higher absorptivity for near infrared rays with a wavelength of 2.5 μm than the glass plate 1. This absorptivity is preferably 0.1 or more with respect to a maximum value of 1, and more preferably 0.2 or more. When the frame 21 is heated in the event of a fire, the radiant heat generated from the frame 21 may be propagated by the near infrared rays. However, since the glass plate 1 transmits near infrared rays, the temperature rise of the peripheral portion 8 of the glass plate 1 is unlikely to occur due to the radiant heat from the frame 21. Therefore, in this embodiment, the absorptivity of the near infrared rays of the heat conductive member 11 is set to be higher than that of the glass plate 1. Moreover, the thermal conductivity of the frame 21 in this embodiment is set to be 20 W / mK or more. As a result, the peripheral portion 8 of the glass plate 1 can easily receive radiant heat from the frame 21 through the heat conductive member 11, so that the temperature difference between the central portion 7 and the peripheral portion 8 of the glass plate 1 can be reduced more quickly by raising the temperature of the peripheral portion 8 of the glass plate 1. Furthermore, the emissivity of the heat conductive member 11 is preferably 0.1 or more with respect to a maximum value of 1, and more preferably 0.2 or more. As a result, heat loss caused by the radiant heat of the frame 21 being reflected by the heat conductive member 11 can be suppressed, so that the radiant heat can be efficiently transferred to the flame-shielding region 2 via the heat conductive member 11.

[0063] The heat conductive member 11 may be configured to have fine irregularities on the surface of the metal foil 12. When the surface of the metal foil 12 has fine irregularities, the surface reflection of radiant heat in the metal foil 12 is suppressed, and the metal foil 12 is more likely to absorb radiant heat. As a result, the heat conductive member 11 can efficiently receive radiant heat from the flame shielding member 20 as well, and heat the peripheral portion 8 of the glass plate 1.

[0064] The metal foil 12 provided in the heat conductive member 11 has a thermal conductivity of 50 W / mK or more, and preferably 100 W / mK or more. When the thermal conductivity of the metal foil 12 is 50 W / mK or more, the thermal conductivity of the heat conductive member 11 can also be increased to 50 W / mK or more. This allows heat from the center 7 of the glass plate 1 to be quickly transferred to the peripheral portion 8 of the glass plate 1 via the heat conductive member 11, and the peripheral portion 8 can be quickly heated. In order to increase the thermal conductivity of the heat conductive member 11, it is more preferable that the thermal conductivity of the metal foil 12 is 100 W / mK or more.

[0065] The metal foil 12 is made of metals or alloys such as Sn, Al, Ag, Cu, and Zn, and contains at least one of Sn, Al, Ag, Cu, and Zn at 50% by weight or more. The thermal conductivity of Sn is 64 W / mK, the thermal conductivity of Al is 204 W / mK, the thermal conductivity of Ag is 418 W / mK, the thermal conductivity of Cu is 372 W / mK, and the thermal conductivity of Zn is 113 W / mK. That is, Sn, Al, Ag, Cu, and Zn all have a thermal conductivity of 50 W / mK or more. Therefore, by the metal foil 12 containing at least one of the above-mentioned metals at 50% by weight or more, the thermal conductivity of the heat conductive member 11 can be easily increased. Among Sn, Al, Ag, Cu, and Zn, Zn is the most preferable because it has an anticorrosive effect of preventing the penetration of moisture, oxygen, etc., which cause corrosion.

[0066] The adhesive 14 is any one of an acrylic, silicone, and natural rubber type. This makes it possible to easily form the adhesive layer 13 in the heat conductive member 11.

[0067] The thermally conductive fine particles 15 have a higher thermal conductivity than the adhesive 14. This allows the thermally conductive member 11 to increase the thermal conductivity of the adhesive layer 13 by the thermally conductive fine particles 15.

[0068] The adhesive layer 13 has a content of thermally conductive fine particles 15 of 50% by weight or more and 90% by weight or less, preferably 60% by weight or more and 80% by weight or less. In this way, the thermally conductive member 11 can ensure both thermal conductivity and adhesiveness in the adhesive layer 13. If the thermally conductive fine particles 15 are less than 50% by weight in the adhesive layer 13, the adhesive layer 13 cannot obtain sufficient thermal conductivity. If the thermally conductive fine particles 15 are more than 90% by weight in the adhesive layer 13, the proportion of the adhesive 14 becomes too low, so that the adhesive strength decreases and the thermally conductive member 11 becomes easily peeled off from the glass plate 1.

[0069] The adhesive layer 13 has a thickness of 10 μm or more and 100 μm or less, and preferably 20 μm or more and 90 μm or less. When the adhesive layer 13 has a thickness of 10 μm or more and 100 μm or less, the heat conductive member 11 can ensure both the thermal conductivity and adhesiveness of the adhesive layer 13. When the adhesive layer 13 has a thickness smaller than 10 μm in the heat conductive member 11, peeling may occur due to a difference in thermal expansion between the metal foil 12 and the glass plate 1 in the event of a fire. On the other hand, when the adhesive layer 13 has a thickness exceeding 100 μm, the thermal conductivity of the heat conductive member 11 including the adhesive layer 13 may be reduced due to the influence of the adhesive 14. Since the adhesive layer 13 includes the adhesive 14 having a lower thermal conductivity than the metal foil 12, the thickness of the adhesive layer 13 is preferably smaller than the thickness of the metal foil 12. For example, when the thickness of the metal foil 12 is 100 μm, the thickness of the adhesive layer 13 can be set to 30 to 50 μm. In this way, the thickness of the adhesive layer 13 can be set to about half that of the metal foil 12 .

[0070] The thermally conductive particles 15 contained in the adhesive layer 13 have an average particle diameter of 10 μm or more and 100 μm or less, preferably 20 μm or more and 90 μm or less. When the particle diameter of the thermally conductive particles 15 is 10 μm or more and 100 μm or less, the thermally conductive member 11 can reliably ensure thermal conductivity in the adhesive layer 13. When the particle diameter of the thermally conductive particles 15 is less than 10 μm, the thermally conductive particles 15 are unevenly arranged in the adhesive layer 13, so that uniform thermal conductivity may not be ensured. On the other hand, when the particle diameter of the thermally conductive particles 15 exceeds 100 μm, the surface area of ​​the thermally conductive particles 15 is small, so that the thermal conductivity of the thermally conductive member 11 may be reduced. The particle diameter of the thermally conductive particles 15 is preferably equal to or less than the thickness of the adhesive layer 13. As shown in FIG. 4, in this embodiment, the thermally conductive member 11 is configured so that the particle diameter of the thermally conductive particles 15 and the thickness of the adhesive layer 13 are the same.

[0071] The thermally conductive fine particles 15 are metal fine particles. When the thermally conductive fine particles 15 are metal fine particles, it is possible to reliably impart thermal conductivity to the adhesive layer 13. The metal fine particles are composed of metals such as Sn, Al, Ag, Cu, Zn, etc., or alloys, and contain at least one of Sn, Al, Ag, Cu, and Zn at 50% by weight or more. In this way, it is possible to easily increase the thermal conductivity of the adhesive layer 13.

[0072] As the metal fine particles, among Sn, Al, Ag, Cu, and Zn, Sn, Zn, and Al, which have low melting points, are preferred. When using metal fine particles with low melting points, even if the adhesive 14 is subjected to combustion heat during a fire and its adhesiveness is reduced, the adhesion between the glass plate 1 and the adhesive layer 13 can be ensured by melting the surfaces of the metal fine particles. In addition, the metal fine particles contained in the adhesive layer 13 may be composed of only one type of metal, or may be a mixture of metal fine particles of different metals.

[0073] The backup material 23 and the elastic support 24 are members for supporting the glass plate 1 on the frame 21, and are therefore made of resin or rubber having a certain degree of elasticity so as not to damage the glass plate 1. The backup material 23 and the elastic support 24 are made of resin or rubber with high thermal insulation properties, and the heat transfer from the center 7 of the glass plate 1, which has become hot due to a fire, to the backup material 23 and the elastic support 24 via the heat conductive member 11 is suppressed. As a result, the heat transferred to the peripheral portion 8 of the glass plate 1 via the heat conductive member 11 increases, so that the temperature of the peripheral portion 8 can be efficiently raised, and the fireproofing can be improved more reliably. In addition, in order to suppress the escape of heat from the heat conductive member 11 to the setting block 22 and to efficiently raise the temperature of the peripheral portion 8 of the glass plate 1, it is desirable that the setting block 22 is also made of a material with high thermal insulation properties.

[0074] A glass window provided in a building or the like is realized by clamping and fixing a glass module 10 between fire-blocking members 20.

[0075] A fire test was carried out to verify the fire resistance of the glass module 10 of this embodiment. As Example 1, a glass module provided with a heat conductive member 11 having metal fine particles in the adhesive layer 13, as Example 2, a glass module provided with a heat conductive member 11 not having metal fine particles in the adhesive layer 13, and as Comparative Example 1, a conventional glass module not provided with the heat conductive member 11 were prepared.

[0076] The glass plate 1 is made of a single layer soda glass that has been subjected to a thermal strengthening treatment and has a plate thickness of 5 mm. The frame 21 is made of aluminum, the backup material 23 is a flame-retardant resin, the elastic support 24 is a fireproof silicone sealant, and the setting block 22 is a fireproof block made of calcium silicate. The heat conductive member 11 used in Examples 1 and 2 is a tape body having a metal foil 12 of Sn foil with a thickness of 100 μm and an adhesive layer 13 with a thickness of 40 μm, and is disposed on the outer plate surfaces 5 and 6 of the flame-shielding region 2. The heat conductive member 11 is disposed at a position 7 mm from the edge (the edge of the end surface 4) toward the center. The adhesive layer 13 of the heat conductive member 11 in Example 1 contains Sn fine particles with a particle size of 40 μm in a dispersed state.

[0077] The fire resistance test was performed assuming a fire breaking out on one side of the glass plate 1. The furnace temperature T was raised for 10 minutes according to the ISO-834 heating curve shown below, and the temperatures at each edge of the glass plate 1 (hereinafter referred to as the edge temperature) and the temperature at the center of the glass plate 1 (hereinafter referred to as the center temperature) were measured after 10 minutes. ISO-834 heating curve: T= 345log(8t+1)+20 t:Heating time (min)

[0078] The temperature difference between the center and the edge of the glass plate 1 usually reaches a maximum value about 10 minutes after the start of the fire test, and thereafter the temperature difference becomes smaller. Therefore, by checking the temperature difference between the center and the edge of the glass plate 1 10 minutes after the start of the fire test, the fire resistance of the glass plates 1 of Example 1, Example 2, and Comparative Example can be compared.

[0079] When the fire test was carried out under the above conditions, 10 minutes after the fire test, the edge temperature was 255°C in Example 1, 232°C in Example 2, and 210°C in Comparative Example 1. The center temperature of the glass plate 1 was 530°C in all of Example 1, Example 2, and Comparative Example 1. From these results, the temperature difference between the center and the edge of the glass plate 1 was 275°C in Example 1, 298°C in Example 2, and 320°C in Comparative Example 1.

[0080] In Examples 1 and 2, when a fire breaks out on one side of the glass plate 1, heat is transferred from the center of the glass plate 1, which has become hot due to the fire, to the edge via the heat conductive member 11. As a result, the temperature of the edge of the glass plate 1 rises, and the temperature difference between the center and the edge, which become very hot due to the heat of combustion of the fire, becomes smaller than in Comparative Example 1.

[0081] On the other hand, in Comparative Example 1, since the heat conductive member 11 is not provided on the glass plate 1, it is not possible to actively raise the temperature of the edges of the glass plate 1. As a result, the temperature difference between the center of the glass plate 1, which becomes extremely hot due to the heat of combustion of a fire, and the edges, which are less susceptible to the heat of combustion of a fire, becomes larger than in Examples 1 and 2.

[0082] The above fire test results show that Example 1 and Example 2 have superior fire resistance to Comparative Example 1. When the test results are examined, it is believed that the superior fire resistance of Example 1 and Example 2 is due to the characteristic configuration in which the heat conductive member 11 is provided from the edge of the glass plate 1 to the outer plate surfaces 5 and 6 of the flame blocking area 2.

[0083] Furthermore, when the surface compressive stress required for the glass plate 1 was examined in Example 1, Example 2, and Comparative Example 1, it was found to be at least 120 MPa in the case of Comparative Example 1, at least 101 MPa in the case of Example 1, and at least 111 MPa in the case of Example 2. From the above results, it became clear that by providing the thermally conductive members 11 on the outer plate surfaces 5 and 6 of the glass plate 1, the glass plate 1 having a relatively low surface compressive stress can be used for a fire-resistant glass module 10.

[0084] [Second embodiment] A second embodiment of the glass unit 100 will be described with reference to Fig. 5. The same members as those in the first embodiment are given the same reference numbers, and the description thereof will be omitted here.

[0085] The heat conductive member 11 may be configured to be able to be arranged on at least one of the first outer plate surface 5 and the second outer plate surface 6 in the non-flame shielding region 3. In this embodiment, the heat conductive member 11 is arranged adjacent to both the outer plate surfaces 5 and 6 of the non-flame shielding region 3 adjacent to the flame shielding region 2 in addition to the flame shielding region 2 of the glass plate 1. Although not shown, the heat conductive member 11 may be arranged on only one of the first outer plate surface 5 and the second outer plate surface 6 in the non-flame shielding region 3. With this configuration, the presence of the heat conductive member 11 fixed to the non-flame shielding region 3 makes it easier for the combustion heat received by the non-flame shielding region 3 of the glass plate 1 to be transferred to the flame shielding region 2 via the heat conductive member 11. This makes it possible to quickly reduce the temperature difference between the non-flame shielding region 3 and the flame shielding region 2 of the glass plate 1. Furthermore, since the heat conductive member 11 is provided on the outer panel surfaces 5, 6 adjacent to the flame-shielding region 2 in the non-flame-shielding region 3, it is possible to reduce the range of the heat conductive member 11 in the non-flame-shielding region 3 and minimize the effect of the heat conductive member 11 on the appearance of the glass plate 1.

[0086] [Third embodiment] A third embodiment of the glass unit 100 will be described with reference to Fig. 6. The same members as those in the first embodiment are given the same reference numbers, and the description thereof will be omitted here.

[0087] In this embodiment, the heat conductive member 11 is provided only on the outer plate surfaces 5, 6 (flame-blocking region 2) of the glass plate 1, and not on the edge surface 4. Even with this configuration, the heat conductive member 11 arranged in the flame-blocking region 2 can transfer heat from the central portion 7 of the glass plate 1, which has become extremely hot due to the heat of combustion in a fire, to the peripheral portion 8 including the edge surface 4, via the heat conductive member 11. This can reduce the temperature difference between the central portion 7 and the peripheral portion 8 of the glass plate 1, thereby improving fire resistance.

[0088] [Fourth embodiment] A fourth embodiment of the glass unit 100 will be described with reference to Fig. 7. The same members as those in the first embodiment are given the same reference numbers, and the description thereof will be omitted here.

[0089] In this embodiment, the heat conductive member 11 is provided from the outer plate surfaces 5, 6 of the glass plate 1 to the frame body 21. In this manner, the heat conductive member 11 may be configured to be able to come into contact with the frame body 21, at least a part of which is the flame shielding member 20. The heat conductive member 11 has a first contact portion 16 and a second contact portion 17. The first contact portion 16 is a portion that is in surface contact with the outer plate surfaces 5, 6 of the glass plate 1. The second contact portion 17 is a portion that is in surface contact with the inner surface 25 of the frame body 21 while being sandwiched between the frame body 21 and the backup material 23. In addition, since the thermal conductivity of the frame body 21 is 20 W / mK or more, it is sufficiently larger than the thermal conductivity of the glass plate 1 (about 1 W / mK), and heat is easily transferred from the frame body 21 to the peripheral portion 8 of the glass plate 1 via the second contact portion 17. With this configuration, two heat transfer paths to the peripheral portion 8 of the glass plate 1 can be secured, one from the central portion 7 of the glass plate 1 and the other from the frame body 21, thereby further promoting heating of the peripheral portion 8 of the glass plate 1.

[0090] [Fifth embodiment] A fifth embodiment of the glass unit 100 will be described with reference to Fig. 8. The same members as those in the first embodiment are given the same reference numbers, and the description thereof will be omitted here.

[0091] In this embodiment, the second heat conductive member 30 is interposed between the flame-shielding region 2 of the glass plate 1 and the frame body 21. The second heat conductive member 30 is disposed between the frame body 21 and the heat conductive member 11 fixed to the flame-shielding region 2. The second heat conductive member 30 is made of a metal having a thermal conductivity of 20 W / mK or more and 250 W / mK or less. If the second heat conductive member 30 is a metal, a material having a higher thermal conductivity than the glass plate 1 can be easily selected. The second heat conductive member 30 has a first contact portion 31 and a second contact portion 32. The first contact portion 31 is a portion that is in surface contact with the heat conductive member 11 fixed to the peripheral portion 8 of the glass plate 1. The second contact portion 32 is bent toward the bottom side of the frame body 21 more than the backup material 23, and is a portion that is in surface contact with the inner surface 25 of the frame body 21. With this configuration, heat can be easily transferred from the frame 21, which has become hot due to a fire, to the peripheral portion 8 of the glass plate 1 through the second heat conductive member 30, which has a thermal conductivity sufficiently higher than that of the glass plate 1 (approximately 1 W / mK). In addition, since the thermal conductivity of the frame 21 is 20 W / mK or more, which is sufficiently higher than the thermal conductivity of the glass plate 1 (approximately 1 W / mK), heat can be easily transferred from the frame 21, which has become hot due to a fire, to the peripheral portion 8 of the glass plate 1 through the second heat conductive member 30. This makes it easier for the peripheral portion 8 of the glass plate 1 to rise in temperature, and therefore the temperature difference between the center portion 7 and the peripheral portion 8 in the glass plate 1 can be quickly reduced. As a result, thermal cracking of the glass plate 1 can be prevented, and the fire resistance of the glass plate 1 can be improved.

[0092] [Other embodiments] (1) In the above embodiment, the heat conductive member 11 is disposed around the entire periphery of the peripheral portion 8 of the glass plate 1 in the glass module 10. However, the heat conductive member 11 may be disposed at intervals in the circumferential direction of the peripheral portion 8 of the glass plate 1. For example, the heat conductive member 11 may be disposed only on the upper and lower sides of the four sides of the glass plate 1. Even if the heat conductive member 11 is disposed on the four sides of the peripheral portion 8 of the glass plate 1, the heat conductive member 11 may not be disposed at the corners where two sides intersect. In the above embodiment, the heat conductive member 11 is disposed over the entire flame-shielding region 2 corresponding to the height direction of the frame 21. However, the heat conductive member 11 may be disposed only in a part of the flame-shielding region 2 adjacent to the end face 4.

[0093] (2) In the above embodiment, the flame-shielding region 2 may be provided in a shape that crosses the central portion of the glass plate 1 in addition to the peripheral edge portion 8 of the glass plate 1, and is appropriately set according to the shape of the frame 21 of the glass plate 1. Moreover, it is sufficient that the flame-shielding region 2 is formed of at least a part of the outer plate surfaces 5, 6 of the glass plate 1 that are covered by the flame-shielding member 20. In other words, the frame 21 may have a shape that does not cover the edge surface 4 of the glass plate 1.

[0094] (3) In the above embodiment, an example was shown in which the frame body 21 of the flame-blocking member 20 is a fixed frame of the sash, but the frame body 21 is not limited to a fixed frame of the sash and may have another configuration, such as a pair of L-shaped angles.

[0095] (4) In the above embodiment, an example was shown in which the flame-blocking member 20 includes the backup material 23 and the elastic support body 24. However, as shown in FIG. 9, the flame-blocking member 20 may be composed of only the frame body 21.

[0096] (5) In the above embodiment, the glass plate 1 is made of single-layer glass. However, as shown in FIG. 10, the glass plate 1 may be made of double-layer glass. In the example of FIG. 10, the glass plate 1 is made of a first glass plate 41, a second glass plate 42, and a spacer 43 disposed between the first glass plate 41 and the second glass plate 42. The first glass plate 41 is tempered glass, and the second glass plate 42 is Low-E glass. A low-reflection film 44a is coated on a surface 44 of the second glass plate 42 facing the first glass plate 41. The heat conductive member 11 is fixed in contact with at least an outer plate surface 45 and an end surface 47 of the first glass plate 41 and an outer plate surface 46 and an end surface 48 of the second glass plate 42. The heat conductive member 11 may further be fixed in contact with the inner surface of the first glass plate 41 and the inner surface of the second glass plate 42.

[0097] In any of the embodiments, the configuration of the heat conductive member 11 or the second heat conductive member 30 is not limited to that shown in Figures 1 to 10. In other words, as long as the heat conductive member 11 is present on the outer plate surface (5, 6, 45, 46) of the glass plate 1 when the glass unit 100 is completed, other configurations may be adopted. [Industrial Applicability]

[0098] The present invention can be applied to a glass module and a glass unit including glass plates, and can be applied not only to single-layer glass but also to double-layer glass. [Explanation of symbols]
