[0020] <First embodiment> Next, specific embodiments having the above-mentioned features will be described in detail with reference to the drawings. In this specification, the "panel thickness direction" refers to the thickness direction of the window-equipped architectural panel. The "panel surface direction" refers to the direction in which the front or back surface of the window-equipped architectural panel extends. The panel surface direction includes the panel's vertical direction and the panel's width direction, which intersects with the panel's vertical direction.

[0021] FIG. 1 shows a fitting device 1 equipped with an example of a window-equipped architectural panel according to the present invention. This fitting device 1 comprises a rectangular frame body 10, a windowed architectural panel 20A that opens and closes an opening within the frame body, and a hinge 15 that rotates the windowed architectural panel 20A at the tail end to open and close.

[0022] The frame body 10 is configured in a rectangular frame shape, comprising horizontal horizontal frame members 11, 12 spaced apart vertically and horizontally, and vertical vertical frame members 13, 14 spaced apart horizontally, and is fixed to an opening in the frame of a building or the like. The horizontal frame members 11, 12 and the vertical frame members 13, 14 are each formed from a hard metal material in a long, linear shape, and are integrated together by welding or the like.

[0023] The windowed architectural panel 20A is a door body that opens and closes the opening in the frame body 10 by rotating around a hinge 15 on the door tail side as a fulcrum. This window-equipped architectural panel 20A comprises two outer panels 21, 22 spaced apart in the panel thickness direction, a penetration A penetrating the two outer panels 21, 22, a first middle rib 30 surrounding the penetration A and fixed to the inner surface of one of the outer panels 21, a second middle rib 40 surrounding the penetration A and fixed to the inner surface of the other outer panel 22, first and second translucent plates 51, 52 supported by the first middle rib 30 and the second middle rib 40 to cover and seal the penetration A, a receiving part B and one ledge 61 that sandwich the end side of the first translucent plate 51 from both sides in the thickness direction, and a receiving part C and the other ledge 62 that sandwich the end side of the second translucent plate 52 from both sides in the thickness direction, with the first middle rib 30 and the second middle rib 40 separated by gaps s1 and s2 (see Figure 2).

[0024] The outer plates 21 and 22 are each formed from a hard metal material into a generally rectangular plate shape when viewed from the front. The upper end and left and right end sides of each outer plate 21 (or 22) are bent toward the other outer plate 22 (or 21) along reinforcing bars 23, 24, 25, and 26, which will be described later.

[0025] Between the inner surfaces of the outer plates 21 and 22, reinforcement ribs 23, 24, 25, and 26 are provided on the upper end side, lower end side, left end side, and right end side, respectively (see FIG. 1).

[0026] The upper, lower, left, and right reinforcing bars 23, 24, 25, and 26 are each formed from a hard metal material in the shape of a long channel steel. These reinforcing bars 23, 24, 25, and 26 are fixed to the inner surfaces of both the outer plates 21 and 22 in contact with each other.

[0027] Rectangular openings 21a and 22a that are elongated in the vertical direction are provided at the center of the outer plates 21 and 22, respectively.

[0028] The through portion A penetrates the two outer plates 21 and 22 in the thickness direction, and is formed between the openings 21a and 22a.

[0029] The first intermediate bone 30 is composed of an elongated upper bone portion 30a along the upper inner edge of the opening 21a, an elongated lower bone portion 30b along the lower inner edge of the opening 21a, an elongated left side bone portion 30c along the left inner edge of the opening 21a, and an elongated right side bone portion 30d along the right inner edge of the opening 21a.

[0030] Similarly, the second intervertebral column 40 is composed of an elongated upper bone portion 40a along the upper inner edge of the opening 22a, an elongated lower bone portion 40b along the lower inner edge of the opening 22a, an elongated left bone portion 40c along the left inner edge of the opening 22a, and an elongated right bone portion 40d along the right inner edge of the opening 22a.

[0031] The vertical cross-sectional shapes of the top, bottom, left, and right bone portions 30a, 30b, 30c, and 30d are the same. Similarly, the vertical cross-sectional shapes of the top, bottom, left, and right bone portions 40a, 40b, 40c, and 40d are the same.

[0032] The bones 30a, 30b, 30c, and 30d may be separate members, but may also be pre-connected to form an integrated member.Similarly, the bones 40a, 40b, 40c, and 40d may be separate members, but may also be pre-connected to form an integrated member.

[0033] The bone portions of the first and second intermediate bones 30 and 40 are formed from a hard metal material in an elongated shape along the inner edge of the through-hole A. Each of the rib portions of the first central rib 30 integrally includes a base piece 31 fixed to the inner surface of the outer panel 21 and a reinforcing piece 32 protruding from the base piece 31 inward in the panel thickness direction. Similarly, each of the rib portions of the second rib 40 integrally includes a base piece 41 fixed to the inner surface of the outer panel 22 and a reinforcing piece 42 protruding inward from the base piece 41 in the panel thickness direction.

[0034] Each base piece 31, 41 is formed in a flat plate shape that fits along the inner surface of the outer plate 21 (or 22), and is fixedly attached to the inner surface of the outer plate 21 (or 22) by a fixing means such as welding.

[0035] The reinforcing piece 32 of the first rib 30 and the reinforcing piece 42 of the second rib 40 have different longitudinal cross-sectional shapes (see FIGS. 2 and 3).

[0036] The reinforcing piece 32 of the first rib 30 has a longitudinal cross-sectional shape with a plurality of bent portions. In more detail, this reinforcing piece 32 integrally comprises a first piece 32a protruding inward in the panel thickness direction, a second piece 32b bent from this first piece 32a toward the penetration portion A, a third piece 32c bent from this second piece 32b toward the other outer panel 22, a fourth piece 32d bent from this third piece 32c toward the opposite side of the penetration portion A, and a fifth piece 32e bent from this fourth piece 32d toward the other outer panel 22 (see Figure 2). Of these pieces, the second piece 32 b functions as a receiving part B that receives the end of the first light-transmitting plate 51 .

[0037] In addition, the reinforcing piece 42 of the second rib 40 has a longitudinal cross-sectional shape that integrally includes a first piece portion 42a that protrudes inward in the panel thickness direction and a second piece portion 42b that protrudes from this first piece portion 42a toward the through portion A (see Figure 2). Of these pieces, the second piece 42 b functions as a receiving portion C that receives the end side of the second light-transmitting plate 52 .

[0038] The reinforcing piece 32 of the first rib 30 and the reinforcing piece 42 of the second rib 40 have different lengths of inward protrusion in the panel thickness direction. That is, in the example shown in Figure 2, the reinforcing piece 32 protrudes inward in the panel thickness direction by a greater amount than the reinforcing piece 42 of the second rib 40.

[0039] Due to the differences in longitudinal cross-sectional shape and length, the natural frequency of the member on the outer panel 21 side including the first rib 30 and the member on the other outer panel 22 side including the second rib 40 is different.

[0040] In addition, a gap s1 is secured in the panel thickness direction between the fourth piece 32d of the first rib 30 and the second piece 42b of the second rib 40, and a gap s2 is secured in the panel surface direction between the fifth piece 32e of the first rib 30 and the first piece 42a of the second rib 40. The first midrib 30 and the second midrib 40 are separated by these gaps s1 and s2.

[0041] The first light-transmitting plate 51 is a rectangular glass plate. The end side of this first light-transmitting plate 51 is sandwiched between one of the pressing edges 61 and the receiving portion B (second piece portion 32b) with the first airtight material 53, the second airtight material 54, etc. interposed therebetween.

[0042] The second light-transmitting plate 52 is a rectangular glass plate that is thinner than the first light-transmitting plate 51, and is disposed substantially parallel to the first light-transmitting plate 51 with a space S (hollow layer) therebetween. The end side of this second light-transmitting plate 52 is sandwiched between the other pressing edge 62 and the receiving portion C (second piece portion 42b) with the first airtight material 53, the second airtight material 54, etc. interposed therebetween.

[0043] One of the flanges 61 is a member having a rectangular frame shape in a front view (see FIG. 1) that covers the inner edge of the opening 21a of one of the outer plates 21. This flange 61 is detachably fastened to the surface of the outer plate 21 by fasteners 71 such as screws, bolts, or rivets. The space inside the frame of this one of the flanges 61 exposes the first light-transmitting plate 51 to the outside.

[0044] The other ledge 62 is a member having a rectangular frame shape in a front view that covers the inner edge of the opening 22a of the other outer plate 22. This ledge 62 is detachably fastened to the surface of the outer plate 22 by fasteners 71. The space inside the frame of the other flange 62 exposes the second light-transmitting plate 52 to the outside.

[0045] Each of the ledges 61 (or 62) may be an integral member having a rectangular frame shape when viewed from the front, but as another example, it may be configured to have four separate side portions.

[0046] The first airtight material 53 is a long, plate-shaped elastic member (e.g., rubber, elastomer resin, etc.) and is sandwiched between the back surface of the first translucent plate 51 and the receiving portion B, along each side of the first translucent plate 51. Four first airtight materials 53 are provided corresponding to the upper end side, lower end side, left end side, and right end side of the first light-transmitting plate 51. These four first airtight materials 53 may be separate bodies or may be connected in advance in the shape of a frame.

[0047] The second airtight material 54 is a fluid filler whose main component is silicone, etc. This second airtight material 54 is filled between the surface of the first light-transmitting plate 51 and the inner surface of one of the ridges 61, along each side of the surface of the first light-transmitting plate 51. This second airtight material 54 retains its elasticity after natural hardening.

[0048] In the drawing, reference numeral 55 denotes a backup material made of an elastic material such as foamed resin. This backup material 55 is sandwiched between the flange 61 and the first light-transmitting plate 51 and between the other flange 62 and the second light-transmitting plate 52, on the inner side of the second airtight material 54, so that the filling amount of the second airtight material 54 is appropriate.

[0049] In the drawing, reference numeral 56 denotes a base that supports the first light-transmitting plate 51 from below on the lower rib portion 30b of the first middle rib 30. The bases 56 are made of rubber or synthetic resin, and a plurality of bases 56 are provided at intervals in the width direction of the panel. The bases 56 are sometimes called setting blocks.

[0050] Next, the characteristics of the manufacturing method for the windowed architectural panel 20A having the above-mentioned configuration will be described in detail. The procedure for assembling the first light-transmitting plate 51 to the first middle rib 30 (see FIG. 4) is as follows: first, a plurality of pedestals 56 are placed at intervals in the width direction of the panel on the lower rib portion 30b of the first middle rib 30. Then, the first airtight material 53 is superimposed on the receiving portion B via an adhesive (for example, adhesive or double-sided adhesive tape).

[0051] Next, the first light-transmitting plate 51 is placed on the base 56 so as to be in contact with the first airtight material 53 . One of the pressing edges 61 is attached to the surface of the outer panel 21 by a fastening device 71, covering the peripheral edge of the first translucent plate 51 and leaving a gap s3 in the first translucent plate 51 to be filled with airtight material (see Figure 5).

[0052] Thereafter, as shown in FIG. 5, a back-up material 55 is pushed into the airtight material filling space (gap s3), and then a second airtight material 54 is filled.

[0053] Similarly, for the other outer panel 22, first, a plurality of bases 56 are placed on the lower rib portion 40b of the second middle rib 40 at intervals in the width direction of the panel, a first airtight material 53 is superimposed on and fastened to the receiving portion C, a second light-transmitting plate material 52 is placed on the base 56 so as to be in contact with the first airtight material 53, and the other push edge 62 is fastened to the surface of the outer panel 21, ensuring a filling space for the airtight material (see Figure 6). Then, after this, the back-up material 55 is pushed into the gap between the inner surface of the flange 62 and the surface of the second light-transmitting plate 52 (the gap for filling the airtight material), and the second airtight material 54 is filled.

[0054] Therefore, according to the building fixture device 1 equipped with the window-equipped architectural panel 20A of the above configuration, the first rib 30 and the second rib 40 are arranged apart in the panel thickness direction, so that these ribs 30, 40 act as a medium to prevent the transmission of vibrations and sound. To explain in more detail, for example, when sound or vibration is transmitted from the outside to the first translucent plate 51, the sound or vibration is attenuated by the first airtight material 53 and the second airtight material 54, etc., and transmitted to the first middle rib 30, but due to the gaps s1, s2 and the space S, it is difficult for the sound or vibration to be transmitted to the second translucent plate 52 and the second middle rib 40.

[0055] In a particularly preferred example of this embodiment, the shapes of the first and second ribs 30 and 40 are made different, and the protrusion amounts of the reinforcing pieces 32 and 42 are made different, thereby making the natural frequency of the one-side member including the first rib 30 different from the natural frequency of the other-side member including the second rib 40, and effectively preventing an increase in vibration and sound due to resonance between the one-side member and the other-side member.

[0056] Furthermore, according to the above manufacturing method, a support structure that suppresses vibration of the first light-transmitting plate 51 and the second light-transmitting plate 52 can be manufactured with good workability in a short time. That is, it is difficult to fill the back side of the first translucent plate material 51 with a fluid back-up material 55, but according to this embodiment, a solid first airtight material 53 is provided on the back side of the first translucent plate material 51, so that the workability is good.

[0057] <Second embodiment> In the embodiment described below, the windowed architectural panel 20A of the above-mentioned building fixture device 1 is replaced with other windowed architectural panels 20B, 20C, and 20D, so the details will mainly focus on the changed parts, and the same symbols will be used for parts that are approximately similar, and duplicate detailed explanations will be omitted.

[0058] The window-equipped architectural panel 20B shown in Figure 7 comprises two outer panels 21, 22 spaced apart in the panel thickness direction, a penetration portion A that passes through the two outer panels 21, 22, a first middle rib 130 that surrounds the penetration portion A and is fixed to the inner surface of one of the outer panels 21, a second middle rib 140 that surrounds the penetration portion A and is fixed to the inner surface of the other outer panel 22, a translucent plate 150 that closes the penetration portion A, and a receiving portion B and a push edge 62 that sandwich the end side of the translucent plate 150 from both sides in the thickness direction. This window-equipped architectural panel 20B is provided with a partial connection portion 160 that partially connects the first rib 130 and the second rib 140 while maintaining gaps s1 and s2 between the first rib 130 and the second rib 140.

[0059] A portion of the inner surface of one of the outer panels 21 near the opening 21 a functions as a receiving portion B that sandwiches the translucent plate 150 between itself and the ledge 62 .

[0060] The first intermediate rib 130 is configured so that the upper, lower, left, and right bone portions surround the penetration portion A, similar to the above-mentioned first intermediate rib 30. The upper, lower, left, and right bone portions may be an integrated member that is connected in advance, or may be separate, individual members.

[0061] Similar to the second intermediate rib 40 described above, the second intermediate rib 140 is configured so that the upper, lower, left, and right bone portions surround the penetration portion A. The upper, lower, left, and right bone portions may be an integrated member that is connected in advance, or may be separate, individual members. The second intermediate bone 140 is located closer to the penetrating portion A than the first intermediate bone 130 .

[0062] The bone portions of the first and second intermediate bones 130 and 140 are formed from a hard metal material in an elongated shape along the inner edge of the through-hole A. Each of the rib portions of the first central rib 130 integrally includes a base piece 131 fixed to the inner surface of the outer panel 21 and a reinforcing piece 132 protruding inward in the panel thickness direction from the base piece 131 (see FIG. 7). Similarly, each of the rib portions of the second rib 140 integrally includes a base piece 141 fixed to the inner surface of the outer panel 22 and a reinforcing piece 142 protruding inward from the base piece 141 in the panel thickness direction.

[0063] Each of the base pieces 131, 141 is formed in a flat plate shape that fits along the inner surface of the outer plate 21 (or 22), and is fixedly attached to the inner surface of the outer plate 21 (or 22) by a fixing means such as welding.

[0064] The reinforcing piece 132 of the first rib 130 protrudes inward in the panel thickness direction from the base piece 131, and its tip is bent toward the panel surface near the inner surface of the opposing outer plate 22. This bent portion is spaced apart from the second rib 140 and the outer plate 22.

[0065] The reinforcing piece 142 of the second rib 140 is provided with a gap S2 in the panel surface direction and a gap S1 in the panel thickness direction relative to the reinforcing piece 132 of the first rib 130. This reinforcing piece 142 protrudes inward in the panel thickness direction from the base piece 141, and its tip side is bent toward the panel surface near the inner surface of the opposing outer plate 21. This bent portion is spaced apart from the first center rib 130 and the outer plate 21.

[0066] In the illustrated example, the partial connection portion 160 is a threaded member such as a screw or bolt, which is inserted into the outer panel 22 from the outside and is threadedly fastened to both the first rib 130 and the second rib 140.

[0067] The light-transmitting plate 150 is an integral composite glass having an internal space S (hollow layer). The light-transmitting plate 150 is formed in the shape of a rectangular frame when viewed from the front, which is slightly larger than the opening 21a of one of the outer plates 21.

[0068] This light-transmitting plate material 150 integrally comprises a first glass plate 151, a second glass plate 152 arranged approximately parallel to the first glass plate 151 with a space S therebetween, a third glass plate 153 superimposed on the second glass plate 152, and a connecting portion 154 that secures a space S between the first glass plate 151 and the second glass plate 152 and connects the first glass plate 151 and the second glass plate 152 at their end portions.

[0069] The first glass plate 151 is formed in the shape of a relatively thick rectangular plate. The two second glass plates 152 and the third glass plate 153 are each formed in a rectangular plate shape that is thinner than the first glass plate 151 .

[0070] To explain the procedure for installing the translucent plate 150 having the above configuration, the translucent plate 150 is inserted into the through-hole A from the inside side (the outer plate 22 side) as shown in the figure, and is placed on the lower rib portion of the second middle rib 140, near the center in the panel thickness direction, via multiple pedestals 56.

[0071] Next, a frame-shaped ledge 62 is superimposed and fastened to the surface of the outer plate 22 so as to cover the inner edge of the opening 22a.

[0072] A back-up material 55 is pressed between the inner surface of the outer plate 21 and the light-transmitting plate 150, and further, a second airtight material 54 is filled in. Similarly, a back-up material 55 is pressed between the inner surface of the ledge 62 of the outer plate 22 and the light-transmitting plate 150, and a second airtight material 54 is filled in between.

[0073] Therefore, with a building fixture device equipped with a window-equipped architectural panel 20B of the above configuration, the gaps S1, S2 between the first rib 130 and the second rib 140, the support structure of the translucent board 150, etc., can prevent vibrations and sounds from the outer panel 21 side from being transmitted to the outer panel 22 side.

[0074] In a particularly preferred example of this embodiment, the first rib 130 and the second rib 140 are partially connected by the partial connection portion 160, so that the rigidity between the two outer plates 21, 22 is high and vibration damping is also excellent.

[0075] Furthermore, a support structure that suppresses vibration of the light-transmitting plate 150 can be produced with good workability in a short time.

[0076] <Third embodiment> The window-equipped architectural panel 20C shown in Figure 8 comprises two outer panels 221, 222 spaced apart in the panel thickness direction, a through-hole A penetrating the two outer panels 221, 222, a first middle rib 230 surrounding the through-hole A and fixed to the inner surface of one of the outer panels 221, a second middle rib 240 surrounding the through-hole A and fixed to the inner surface of the other outer panel 222, a translucent plate 250 covering the through-hole A, and a receiving portion B and a push edge 260 that sandwich the end side of the translucent plate 250 from both sides in the thickness direction, ensuring a gap s1 in the panel thickness direction between the first middle rib 230 and the second middle rib 240.

[0077] One of the outer panels 221 has an opening 221a that is rectangular in front view and forms a through-hole A at the center. The inner edge of this opening 221a is bent inward into a U-shape in vertical cross section (see FIG. 8), and the inner surface of the panel serves as a receiving portion B for receiving the light-transmitting plate 250.

[0078] The other outer panel 222 has an opening 222a at the center that serves as the through-hole A. The inner edge of this opening 222a is bent toward the inside of the panel into an L-shape in vertical cross section (see FIG. 8), and a push-in edge 260 is detachably fastened to the bent surface.

[0079] The first intermediate rib 230, like the above-described first intermediate rib 30, is composed of upper, lower, left, and right bone parts that surround the penetrating part A in a rectangular frame shape. The upper, lower, left, and right bone parts may be an integrated member that is connected in advance, or may be separate, individual members.

[0080] Similar to the second midrib 40 described above, the second midrib 240 is also composed of upper, lower, left, and right bone parts that surround the penetrating part A in a rectangular frame shape. The upper, lower, left, and right bone parts may be an integrated member that is connected in advance, or may be separate, individual members. The second rib 240 is separated from the first rib 230 by a gap s1, and does not contact the inner surface of the other outer plate 221.

[0081] The bone portions of the first and second ribs 230 and 240 are made of a hard metal material and are elongated members extending in the panel surface direction. Each of the bone portions of the first middle rib 230 integrally comprises a base piece 231 fixed to the inner surface of the outer panel 221 and a reinforcing piece 232 that protrudes inward from the base piece 231 in the panel thickness direction and has its tip bent toward the panel surface (see Figure 8).

[0082] Each of the bone portions of the second rib 240 integrally comprises a base piece 241 fixed to the inner surface of the outer plate 222 and reinforcing pieces 242, 243 bent on the side of the base piece 241 facing the through-portion A and on the side opposite the through-portion A, and is formed in a U-shape in vertical cross section (see Figure 8).

[0083] The light-transmitting plate 250 is a composite glass made by overlapping two rectangular glass plates together. The light-transmitting plate 250 is located between the receiving portion B and the push edge 260 in the panel thickness direction, and is placed on the upper surface of the lower rib portion 230b that constitutes the first middle rib 230 via the base 56.

[0084] The flanges 260 are elongated members extending across the width of the panel and made of a hard metal material. The flanges 260 are detachably fixed to the upper and lower inner edges of the opening 222a of the outer panel 222. In FIG. 8, reference numeral 72 denotes a fastener (for example, a screw, a bolt, a rivet, or the like) that fastens and fixes the ledge 260 to the inner edge.

[0085] A back-up material 55 is filled between the receiving portion B and the light-transmitting plate 250, and between the light-transmitting plate 250 and the ledge 260, and a second airtight material 54 is filled in.

[0086] In Fig. 8, reference numeral 233 denotes a reinforcing material that reinforces the lower bone portion 230b that constitutes the first central rib 230. Also in the same figure, reference numerals 23 and 24 denote reinforcing bones that join the outer plates 221 and 222 at their upper and lower ends. In the figure, reference numeral 27 denotes a core material that is provided between the outer plates 221 and 222 to suppress flapping of the outer plates 21 and 22 and improve heat insulation.

[0087] Therefore, with the window-equipped architectural panel 20C having the above-described configuration, the gap S1 between the first rib 230 and the second rib 240, the support structure of the translucent plate 250, etc., can prevent vibrations and sounds from the outer panel 221 from being transmitted to the outer panel 222. Furthermore, a support structure for the light-transmitting plate 250 with good sound insulation properties can be produced with good workability in a short time.

[0088] <Fourth embodiment> The window-equipped architectural panel 20D shown in Figure 9 comprises two outer panels 321, 322 spaced apart in the panel thickness direction, a through hole A that penetrates the two outer panels 321, 322, a first middle rib 330 that surrounds the through hole A and is fixed to the inner surface of one of the outer panels 321, a second middle rib 340 that surrounds the through hole A and is fixed to the inner surface of the other outer panel 322, a plurality of translucent plates 351, 352 that close the through hole A, and receiving parts B and push edges 361, 362 that sandwich the end sides of the translucent plates 351, 352 in the thickness direction, thereby ensuring a gap s1 in the panel thickness direction between the first middle rib 330 and the second middle rib 340.

[0089] One of the outer plates 321 has an opening 321a, which serves as a penetration part A, at the center and is rectangular in front view. The inner surface of the outer plate 321 , along the inner edge of the opening 321 a , functions as a receiving portion B for receiving the light-transmitting plate 351 .

[0090] The other outer panel 322 has an opening 222a at the center that serves as the through-hole A. The inner edge of this opening 222a is bent toward the inside of the panel into an L-shape in vertical cross section (see FIG. 9), and a push-in edge 362 is detachably fastened to the bent surface.

[0091] The first intermediate rib 330, like the above-described first intermediate rib 30, is composed of upper, lower, left, and right bone parts surrounding the penetration part A. These upper, lower, left, and right bone parts may be an integrated member that is connected in advance, or may be separate, individual members.

[0092] Similar to the second midrib 40 described above, the second midrib 340 is also composed of upper, lower, left, and right bone parts surrounding the penetration part A. These upper, lower, left, and right bone parts may be an integrated member that is connected in advance, or may be separate, individual members. The second rib 340 is separated from the first rib 330 by a gap s1 and does not contact the outer plate 321 either.

[0093] The first and second ribs 330, 340 are each formed from a hard metal material in an elongated shape extending in the panel surface direction.

[0094] The bone portion of the first intermediate rib 330 is a rectangular cylindrical member (see FIG. 9). The first intermediate rib 330 in the illustrated example is made up of two combined members each having a U-shaped cross section, but it can also be made up of a single member. The first intermediate rib 330 is fixed by a fixing means such as welding. The portion of this first rib 330 that protrudes toward the inside of the panel functions as a reinforcing piece, and also functions as a fastening portion to which a pressing edge 361 (described later) is fastened.

[0095] The bone portion of the second intermediate rib 340 is formed in a U-shaped cross section and is fixed to the outer plate 322 by a fixing means such as welding. The portion of this second rib 340 that protrudes toward the inside of the panel functions as a reinforcing piece, and also functions as a fastening portion to which the pressing edge 362 is fastened.

[0096] The ridges 361 and 362 are formed of a hard metal material in a long shape extending in the width direction of the panel, similar to the ridge 260 described above. One of the flanges 361 is detachably fixed to the upper and lower frames constituting the first middle rib 330 by fasteners 72, respectively. The other flange 362 is detachably fixed to the upper and lower frames constituting the second middle rib 340 by fasteners 72, respectively.

[0097] The light-transmitting plate 351 is a rectangular glass plate. The end of the light-transmitting plate 351 is located between the receiving portion B on the inner surface of the outer plate 321 and the push edge 361 .

[0098] A first airtight material 53 is sandwiched between the receiving portion B and the light-transmitting plate 351, and a second airtight material 54 is applied to the outside of the first airtight material 53 so as to prevent any gaps from forming. A back-up material 55 is sandwiched between the light-transmitting plate 351 and the flange 361, and a second airtight material 54 is applied to the outside of the back-up material 55 so as to prevent any gaps from forming.

[0099] The light-transmitting plate 352 is a rectangular glass plate that is thicker than the light-transmitting plate 351, and is disposed substantially parallel to the light-transmitting plate 351 with a space S therebetween. The end side of this light-transmitting plate 352 is located between one pressing edge 361 and the other pressing edge 362 .

[0100] The first airtight material 53 is sandwiched between the flange 361 and the light-transmitting plate 352 . A back-up material 55 is sandwiched between the light-transmitting plate 352 and the flange 362, and a second airtight material 54 is applied to the outside of the back-up material 55 so as to prevent any gaps from forming.

[0101] Therefore, according to the window-equipped architectural panel 20D shown in Figure 9, the gap S1 between the first rib 330 and the second rib 340, and the support structure of the translucent plates 351, 352, etc., can prevent vibrations and sound from the outer panel 321 from being transmitted to the outer panel 322. Furthermore, the support structure for the light-transmitting plates 351 and 352, which has good sound insulation properties, can be produced with good workability in a short time.

[0102] <Other variations> In the windowed architectural panels 20A to 20D configured as described above, a reinforcing structure as shown in Figure 10 may be added at a position away from the through-hole A, if necessary, especially when the through-hole A and the translucent plate material are relatively smaller than the outer panels 21, 22. This reinforcing structure includes a long first rib 430 that runs along the inner surface of the outer plate 21 and a long second rib 440 that runs along the inner surface of the outer plate 22 .

[0103] The first rib 430 is integrally formed and includes a flat base piece 431 that contacts the inner surface of the outer panel 21, and a reinforcing piece 432 that protrudes inward in the panel thickness direction from the base piece 431 and has an L-shaped cross section with its tip bent. This first rib 430 does not contact the second rib 440 or the other outer panel 22.

[0104] The second rib 440 is integrally formed and includes a flat base piece 441 that contacts the inner surface of the outer plate 22, a first reinforcing piece 442 that protrudes inward in the panel thickness direction from one end of the base piece 441, and a second reinforcing piece 443 that protrudes inward in the panel thickness direction from the other end of the base piece 441 and has an L-shaped cross section with a bent tip. This second rib 440 does not contact either the first rib 430 or the outer plate 21.

[0105] The area where the base piece 431 of the first middle rib 430 contacts the outer plate 21 is larger than the area where the base piece 441 of the second middle rib 440 contacts the other outer plate 22. The second midrib 440 is formed to be thinner than the first midrib 430 . The reinforcing piece 432 of the first rib 430 is located between the first reinforcing piece 442 and the second reinforcing piece 443 of the second rib 440 . A gap s1 is secured between the base piece 441 of the second rib 440 and the reinforcing piece 432 of the first rib 430.

[0106] Therefore, with the reinforcing structure shown in Figure 10, the first middle rib 430 and the second middle rib 440 can suppress the vibration of the outer panels 21 and 22 in the thickness direction, and the gap s1 can prevent vibrations and sound from being transmitted from the outer panel 21 side to the outer panel 22 side. Furthermore, due to the differences in area, shape, thickness, etc. between the first rib 430 and the second rib 440, the natural frequencies of the components on the outer panel 21 side and the components on the outer panel 22 side are made different, thereby preventing an increase in vibration and noise due to resonance.

[0107] In the above-described embodiment, a transparent or translucent glass plate is used as the translucent plate material, but other examples of the translucent plate material include a translucent plate material other than a glass plate, such as a polycarbonate plate or an acrylic plate.

[0108] Furthermore, according to the above-described embodiment, the windowed architectural panel of the present invention is configured as a door body (opening door), but this windowed architectural panel can be applied to fittings such as sliding doors, folding doors, windows, shoji screens, partitions, shutter curtains, etc.

[0109] Furthermore, the present invention is not limited to the above-described embodiments, and can be modified as appropriate within the scope of the present invention. [Explanation of symbols]
