  FIG. 1 is a front view showing a lighting structure according to an embodiment. FIG. 2 is a cross-sectional view taken along line II-II in FIG. In FIG. 2, the left side is the outdoor side, and the right side is the indoor side. FIG. 3 is a cross-sectional view taken along line III-III in FIG. In FIG. 3, the upper side is the outdoor side, and the lower side is the indoor side.

  The daylighting structure has a plurality of multilayer glasses 10 arranged in a plane as shown in FIG. In FIG. 1, the multiple glass layers 10 are arranged horizontally at intervals, but may be arranged vertically at intervals, or may be arranged vertically and horizontally at intervals.

  The multilayer glass 10 is attached to a frame 20 such as a window frame, and allows outdoor light such as sunlight to pass through the room. The window may be, for example, a building window or a vehicle window.

  The multi-layer glass 10 is an on-site construction type that uses an existing glass plate attached to the frame 20 as a part of the multi-layer glass. In the case of on-site construction type, it is possible to reduce the construction cost and shorten the construction period. In addition, existing glass plates and existing frames can be reused as they are, and resource waste can be reduced.

  The multilayer glass 10 has a frame shape that forms a space SP between the first glass plate 11, the second glass plate 12 facing the first glass plate 11, and the first glass plate 11 and the second glass plate 12. Spacer 13.

  The first glass plate 11 is an existing glass plate, and is fixed to the inside of a fixing groove 21 formed on the inner periphery of the frame 20 by a fixing member 22 or the like. The first glass plate 11 is untempered glass or tempered glass. The tempered glass may be either heat tempered glass or chemically tempered glass.

  The second glass plate 12 is a new glass plate, is smaller than the existing glass plate, is disposed outside the fixed groove 21, and is not fixed inside the fixed groove 21. The second glass plate 12 faces the first glass plate 11, and is disposed, for example, on the indoor side of the first glass plate 11. Similar to the first glass plate 11, the second glass plate 12 is untempered glass or tempered glass.

  In addition, although the 2nd glass plate 12 of this embodiment is arrange | positioned by the indoor side of the 1st glass plate 11, you may arrange | position by the outdoor side of the 1st glass plate 11. FIG.

  The spacer 13 is formed in a frame shape inside the frame 20 and surrounds the space SP. The space SP forms a heat insulating layer. The spacer 13 is an extruded product of resin mixed with a desiccant. The desiccant dries the space SP and prevents condensation in the space SP.

  The spacer 13 may have a moisture-proof layer that suppresses the penetration of moisture in the atmosphere into the space SP. The moisture-proof layer is made of, for example, a metal tape, and is disposed on the outer side of the extruded product (on the side opposite to the space SP with respect to the extruded product). The moisture-proof layer may be disposed inside the spacer 13, and another layer may be disposed outside the moisture-proof layer.

  In addition, although the spacer 13 of this embodiment is an extrusion molded product of resin and has flexibility, the structure of the spacer 13 is not specifically limited. For example, the spacer may be composed of a metal hollow member and a desiccant accommodated in the hollow member. An opening may be provided on the inner peripheral surface of the hollow member, and the internal space of the hollow member may communicate with the space SP.

  The multilayer glass 10 includes, for example, a primary seal 14, a secondary seal 15, and a Low-E (Low Emissivity) film 17 in addition to the first glass plate 11, the second glass plate 12, and the spacer 13.

  The primary seal 14 is disposed between the first glass plate 11 and the spacer 13, seals the space therebetween, and bonds the space therebetween. Further, the primary seal 14 is disposed between the spacer 13 and the second glass plate 12, and seals between them and bonds them therebetween.

  The secondary seal 15 is disposed so as to surround the spacer 13, seals between the first glass plate 11 and the second glass plate 12, and adheres between them. The spacer 13 is formed smaller than the first glass plate 11 and the second glass plate 12 so that the secondary seal 15 can bond the first glass plate 11 and the second glass plate 12. The secondary seal 15 corresponds to the seal member described in the claims.

  The Low-E film 17 restricts the passage of heat by suppressing radiant heat transfer. The Low-E film 17 is formed, for example, on the surface of the second glass plate 12 as a new glass plate facing the first glass plate 11.

  The Low-E film 17 may be a general film, for example, a laminated film including a transparent dielectric film, an infrared reflective film, and a transparent dielectric film in this order. Typical examples of the transparent dielectric film include metal oxides and metal nitrides. Typical metal oxides include zinc oxide and tin oxide. A typical example of the infrared reflecting film is a metal film. A typical metal film is silver (Ag). Here, one or more infrared reflective films may be formed between the transparent dielectric films.

  The Low-E film 17 may be accommodated in the space SP and does not have to protrude from the space SP. Since the space SP is isolated from the atmosphere, contact between moisture in the atmosphere and the Low-E film 17 can be prevented, and deterioration of the Low-E film 17 can be limited.

  In addition, although the Low-E film | membrane 17 of this embodiment does not protrude from space SP, as shown in FIG. 4, you may protrude. For example, the Low-E film 17 may be formed on the entire surface of the second glass plate 12 facing the first glass plate 11 or may not be trimmed. The Low-E film 17 may be formed of a material that does not contain silver in order to suppress deterioration due to moisture in the atmosphere.

  By the way, as shown in FIG. 3, the lighting structure has the connection member 23 which connects the some 2nd glass plate 12 adjacent. For example, the connecting member 23 may connect the adjacent second glass plates 12 by connecting a plurality of adjacent spacers 13. The connecting member 23 may connect the upper ends (see FIG. 1) of the plurality of adjacent spacers 13. The connecting member 23 is made of, for example, a wire. The end of the connecting member 23 may be embedded in the secondary seal 15.

  FIG. 5 is a perspective view showing an attachment state of the connecting member to the spacer according to the first modification. FIG. 5 shows the spacers in an exploded manner. The spacer 13A shown in FIG. 5 includes a plurality of hollow spacers 13Aa and 13Aa and a corner key 13Ab that connects the plurality of hollow spacers 13Aa and 13Aa. The corner key 13Ab connects a plurality of hollow spacers 13Aa and 13Aa vertically. The spacer 13A can be divided and transported into a plurality of parts, and the spacer 13A can be easily transported. The end of the connecting member 23 may be attached to the corner key 13Ab.

  FIG. 6 is a perspective view showing an attachment state of the connecting member to the spacer according to the second modification. In FIG. 6, the spacer is shown in an exploded manner. The spacer 13B shown in FIG. 6 includes a plurality of hollow spacers 13Ba and 13Ba and a straight key 13Bb connecting the plurality of hollow spacers 13Ba and 13Ba. The straight key 13Bb coaxially connects the plurality of hollow spacers 13Ba and 13Ba. The spacer 13B can be divided and transported into a plurality of parts, and the spacer 13B can be transported easily. The end of the connecting member 23 may be attached to the straight key 13Bb.

  In addition, although the connection member 23 of this embodiment is comprised with a wire, the structure of the connection member 23 is not specifically limited. For example, the connecting member 23 may be configured by a plate-shaped metal fitting.

  FIG. 7 is a flowchart illustrating a method for manufacturing a lighting structure according to an embodiment. FIG. 8 is a cross-sectional view showing the bonding step of FIG. 9 is a cross-sectional view showing the bonding step of FIG. 7 following FIG.

  As shown in FIG. 7, the manufacturing method of a lighting structure has preparatory process S11, bonding process S12, connection process S13, and sealing process S14.

  In the preparation step S <b> 11, the second glass plate 12 and the spacer 13 are prepared at the existing site of the first glass plate 11.

  On the surface of the second glass plate 12 facing the first glass plate 11, a Low-E film 17 may be formed in advance at the factory. The Low-E film 17 is protected from moisture in the atmosphere by a protective member, and the protective member is peeled off at the existing site of the first glass plate 11.

  The 2nd glass plate 12 and the spacer 13 may be separately conveyed to the spot. Each packing size is small and easy to carry. In addition, the 2nd glass plate 12 and the spacer 13 may be conveyed to the spot in the assembled state.

  The spacer 13 contains resin and has flexibility. Therefore, when the spacer 13 is transported to the site separately from the second glass plate 12, it can be rolled and transported. Therefore, the packing size is further reduced and transportation is easier.

  Since the spacer 13 includes a desiccant, the spacer 13 may be rolled and housed in a can. The size of the can can be reduced, and it is easy to ensure the airtightness of the can.

  In bonding process S12, as shown in FIG.8 and FIG.9, the 2nd glass plate 12 is bonded via the spacer 13 with respect to the 1st glass plate 11, and the 1st glass plate 11 and the 2nd glass plate 12 are used. A space SP is formed between them.

  In the bonding step S <b> 12, first, as shown in FIG. 8, the spacer 13 is fixed to the first glass plate 11. Since the spacer 13 contains resin, it can be bent. By fixing the spacer 13 to the first glass plate 11 while bending the spacer 13 and connecting both ends of the spacer 13, the spacer 13 can be formed in a frame shape. It is also possible to form a frame by connecting a plurality of linear spacers 13.

  Next, in the bonding step S12, the second glass plate 12 is fixed to the spacer 13 as shown in FIG. At this time, in order to form a gap between the second glass plate 12 and the frame 20, the setting block 30 may be attached to the lower portion of the frame 20 in advance. The setting block 30 supports the second glass plate 12 from below, thereby forming a gap between the second glass plate 12 and the frame 20.

  In the present embodiment, the second glass plate 12 is fixed to the spacer 13 after the spacer 13 is fixed to the first glass plate 11, but the order may be reversed. That is, after the spacer 13 is fixed to the second glass plate 12, the first glass plate 11 may be fixed to the spacer 13. Moreover, when the 2nd glass plate 12 and the spacer 13 are conveyed to the spot in the assembled state as mentioned above, they are fixed with respect to the 1st glass plate 11 in the assembled state.

  In the connecting step S <b> 13, a plurality of adjacent second glass plates 12 are connected by a connecting member 23. For example, as shown in FIG. 3, the connecting member 23 may connect the adjacent second glass plates 12 by connecting a plurality of adjacent spacers 13. The connecting member 23 is made of, for example, a wire.

  In addition, although connection process S13 shown in FIG. 7 is performed after bonding process S12, you may be performed before bonding process S12 or in the middle of bonding process S12. For example, the connecting step S <b> 13 may be performed before the spacer 13 is fixed to the first glass plate 11, or after the spacer 13 is fixed to the first glass plate 11, the second glass plate 12 is fixed to the spacer 13. It may be done before

  In the sealing step S14, the material of the secondary seal 15 is poured into the gap between the frame 20 and the second glass plate 12, and the material is solidified. The secondary seal 15 bonds the first glass plate 11 and the second glass plate 12 outside the spacer 13. The end of the connecting member 23 is embedded in the secondary seal 15. Thereby, the multilayer glass 10 shown in FIGS. 1-3 is obtained.

  As described above, according to the present embodiment, the connecting member 23 connects a plurality of adjacent second glass plates 12. Therefore, for example, in the one multi-layer glass 10, the second multi-layer glass 10 can suppress the second glass plate 12 from dropping due to the spacer 13 falling off from the first glass plate 11. Moreover, the hole processing of the flame | frame 20 is unnecessary.

  Moreover, according to this embodiment, the connection member 23 connects the some 2nd glass plate 12 by connecting the some spacer 13 which adjoins. Since an existing part is used as a part for attaching the connecting member 23 to the second glass plate 12, an increase in the number of parts can be prevented.

  Furthermore, according to the present embodiment, the end of the connecting member 23 is embedded in the secondary seal 15. The secondary seal 15 bonds the first glass plate 11 and the second glass plate 12 outside the spacer 13. Therefore, dropping of the connecting member 23 can be suppressed.

  When the end of the connecting member 23 is embedded in the secondary seal 15, the connecting member 23 may not be attached to the spacer 13. The connecting member 23 can connect a plurality of second glass plates by connecting a plurality of secondary seals 15. Also in this case, an increase in the number of parts can be prevented.

  The embodiment of the daylighting structure has been described above, but the present invention is not limited to the above embodiment and the like, and various modifications and improvements can be made within the scope of the gist of the present invention described in the claims. is there.
