<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.

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.

The frame body 10 is configured in a rectangular frame shape and comprises 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 body of a building or the like.
The horizontal frame members 11, 12 and the vertical frame members 13, 14 are each formed of a hard metal material in a long, linear shape and are integrated together by welding or the like.

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 light-transmitting 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 portion B and one ledge 61 that sandwich the end side of the first light-transmitting plate 51 from both sides in the thickness direction, and a receiving portion C and the other ledge 62 that sandwich the end side of the second light-transmitting 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).

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.

Struts 23, 24, 25, and 26 are provided between the inner surfaces of the outer panels 21 and 22 on the upper, lower, left, and right ends, respectively (see Figure 1).

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 each fixed in contact with the inner surfaces of both outer panels 21 and 22.

Elongated rectangular openings 21a and 22a are provided in the center of the outer panels 21 and 22, respectively.

Penetration section A penetrates the two outer panels 21, 22 in the thickness direction and is formed between the openings 21a, 22a mentioned above.

The first metacarpal bone 30 is composed of an elongated upper bone portion 30a that runs along the upper inner edge of the opening 21a, an elongated lower bone portion 30b that runs along the lower inner edge of the opening 21a, an elongated left bone portion 30c that runs along the left inner edge of the opening 21a, and an elongated right bone portion 30d that runs along the right inner edge of the opening 21a.

Similarly, the second intercostal bone 40 is composed of an elongated upper bone portion 40a that runs along the upper inner edge of the opening 22a, an elongated lower bone portion 40b that runs along the lower inner edge of the opening 22a, an elongated left bone portion 40c that runs along the left inner edge of the opening 22a, and an elongated right bone portion 40d that runs along the right inner edge of the opening 22a.

The vertical cross-sectional shapes of the upper, lower, left, and right bone portions 30a, 30b, 30c, and 30d are the same. Similarly, the vertical cross-sectional shapes of the upper, lower, left, and right bone portions 40a, 40b, 40c, and 40d are the same.

Note that bones 30a, 30b, 30c, and 30d may each be separate members, but they may also be pre-connected, integrated members. Similarly, bones 40a, 40b, 40c, and 40d may each be separate members, but they may also be pre-connected, integrated members.

The bone portions of the first and second intermediate bones 30, 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 inward from the base piece 31 in the panel thickness direction.
Similarly, each of the bone portions of the second center 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.

Each base piece 31, 41 is formed as a flat plate 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.

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

The reinforcing piece 32 of the first intermediate 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 side of the first light-transmitting plate 51 .

In addition, the reinforcing piece 42 of the second middle bone 40 has a longitudinal cross-sectional shape that integrally has 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-hole A side (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 .

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 protrudes inward in the panel thickness direction.

Due to the differences in longitudinal cross-sectional shape and length described above, the natural frequencies of the member on the outer panel 21 side, including the first center rib 30, and the member on the other outer panel 22 side, including the second center rib 40, are different.

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

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

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 translucent plate 52 is clamped between the other pressing edge 62 and the receiving portion C (second piece 42b) with the first airtight material 53 and the second airtight material 54, etc. interposed therebetween.

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 21 a 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.

The other ridge 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 panel 22. This ridge 62 is detachably fastened to the surface of the outer panel 22 by fasteners 71.
The space inside the frame of the other ledge 62 exposes the second light-transmitting plate 52 to the outside.

Each ridge 61 (or 62) may be a single, rectangular frame-shaped member when viewed from the front, but as an alternative, it may be configured with four separate sides.

The first airtight material 53 is a long, plate-shaped elastic material (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 a frame shape.

The second airtight material 54 is a fluid filler whose main component is silicone or the like. This second airtight material 54 is filled between the surface of the first translucent plate 51 and the inner surface of one of the ridges 61, along each side of the surface of the first translucent plate 51. This second airtight material 54 retains its elasticity after natural hardening.

In the figure, 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 translucent plate 51, and between the other flange 62 and the second translucent plate 52, on the farther side of the second airtight material 54, so that the filling amount of the second airtight material 54 is appropriate.

In the figure, reference numeral 56 denotes a base that supports the first translucent plate 51 from below on the lower rib portion 30b of the first backbone 30. These bases 56 are made of rubber or synthetic resin, and multiple bases 56 are provided at intervals across the width of the panel. These bases 56 are sometimes called setting blocks.

Next, the characteristics of the manufacturing method for the windowed architectural panel 20A having the above-described 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 panel width direction 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).

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 .
Then, one of the press edges 61 is attached to the surface of the outer panel 21 by a fastening device 71, covering the peripheral side of the first translucent plate 51 and leaving a gap s3 in the first translucent plate 51 to serve as an allowance for filling with airtight material (see Figure 5).

After this, as shown in Figure 5, back-up material 55 is pushed into the airtight material filling space (gap s3), and the second airtight material 54 is filled in.

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 translucent plate material 52 is placed on the base 56 so as to be in contact with the first airtight material 53, and the other flange 62 is fastened to the surface of the outer panel 21, ensuring a filling space for the airtight material (see Figure 6).
Then, the back-up material 55 is pressed into the gap between the inner surface of the ledge 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 in.

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 at a distance 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 material 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 material 52 and the second middle rib 40.

In a particularly preferred example of this embodiment, the first and second ribs 30 and 40 have different shapes, and the reinforcing pieces 32 and 42 have different protrusion amounts. This causes the natural frequency of the member on one side including the first rib 30 to differ from the natural frequency of the member on the other side including the second rib 40, thereby effectively preventing an increase in vibration and sound due to resonance between the member on one side and the member on the other side.

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 produced 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 the 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.

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

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.

The portion of the inner surface of one of the outer panels 21 near the opening 21a functions as a receiving portion B that sandwiches the translucent plate 150 between it and the ledge 62.

The first rib 130, like the first rib 30 described above, 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 a pre-connected, integrated member, or may be separate, individual members.

Similar to the second midrib 40 described above, the second midrib 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 .

The first and second intermediate bones 130, 140 are each 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 center 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 center 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.

Each base piece 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.

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 panel 22. This bent portion is spaced apart from the second rib 140 and the outer panel 22.

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.

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

The translucent plate 150 is a single piece of composite glass with an internal space S (hollow layer). This translucent plate 150 is formed into a rectangular frame shape when viewed from the front, slightly larger than the opening 21a of one of the outer panels 21.

This translucent plate 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 ends.

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 into a rectangular plate shape that is thinner than the first glass plate 151 .

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

Next, a frame-shaped batten 62 is superimposed and fastened to the surface of the outer panel 22 so as to cover the inner edge of the opening 22a.

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 ridge 62 of the outer panel 22 and the translucent plate 150, and a second airtight material 54 is filled in between.

Therefore, with a fitting device equipped with the window-equipped architectural panel 20B configured as described above, the gaps S1, S2 between the first rib 130 and the second rib 140, and the support structure of the translucent plate 150, etc., can prevent vibrations and sound from the outer panel 21 from being transmitted to the outer panel 22.

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, resulting in high rigidity between the two outer panels 21, 22 and excellent vibration damping.

In addition, a support structure that suppresses vibration of the translucent plate material 150 can be produced with ease and in a short amount of time.

<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 that penetrates the two outer panels 221, 222, a first middle rib 230 that surrounds the through-hole A and is fixed to the inner surface of one of the outer panels 221, a second middle rib 240 that surrounds the through-hole A and is fixed to the inner surface of the other outer panel 222, a translucent plate 250 that closes 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.

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

The other outer panel 222 has an opening 222a in the center that serves as the penetration A. The inner edge of this opening 222a is bent toward the inside of the panel into an L-shaped cross section (see Figure 8), and a ledge 260 is removably attached to the bent surface.

The first rib 230, like the first rib 30 described above, is composed of upper, lower, left, and right bone sections that surround the penetration section A in a rectangular frame shape. The upper, lower, left, and right bone sections may be pre-connected as an integrated member, or may be separate, individual members.

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 penetration 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 parts.
This 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.

The bone portions of the first rib 230 and the second rib 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).

In addition, each of the bone portions of the second center 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 penetration portion A side and the opposite side of the penetration portion A side of the base piece 241, and is formed into a U-shaped vertical cross section (see Figure 8).

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

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 222 a 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.

Back-up material 55 is packed between the receiving portion B and the translucent plate 250, and between the translucent plate 250 and the ledge 260, and second airtight material 54 is filled in.

In Fig. 8, reference numeral 233 denotes a reinforcing member that reinforces the lower rib portion 230b that constitutes the first central rib 230. Also in the same figure, reference numerals 23 and 24 denote strength ribs that join the outer plates 221 and 222 at their upper and lower ends.
Also, 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.

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 material 250, etc., can prevent vibrations and sounds from the outer panel 221 side from being transmitted to the outer panel 222 side.
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.

<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 cover the through-hole A, and receiving portions 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.

One of the outer plates 321 has an opening 321a, which serves as a penetration portion 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 .

The other outer panel 322 has an opening 222a in the center that serves as the penetration A. The inner edge of this opening 222a is bent toward the inside of the panel into an L-shaped cross section (see Figure 9), and a ledge 362 is removably attached to the bent surface.

The first rib 330, like the first rib 30 described above, is composed of upper, lower, left, and right bone sections that surround the penetration section A. These upper, lower, left, and right bone sections may be pre-connected as an integrated member, or may be separate, individual members.

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

The first and second ribs 330, 340 are made of hard metal and are elongated in the direction of the panel surface.

The bone portion of the first intermediate rib 330 is a rectangular cylindrical member (see FIG. 9). The illustrated first intermediate rib 330 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 push edge 361 (described later) is fastened.

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.

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 removably fixed to the upper and lower frames that make up the first middle rib 330 by fasteners 72, respectively.
The other push edge 362 is removably fixed to the upper and lower frames that make up the second backbone 340 by fasteners 72, respectively.

The light-transmitting plate 351 is a rectangular glass plate.
The end side of this light-transmitting plate 351 is located between the receiving portion B on the inner surface of the outer plate 321 and the ledge 361 .

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.

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 ledge 361 and the other ledge 362 .

The first airtight material 53 is sandwiched between the ledge 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.

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 sounds 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 having good sound insulation properties can be produced with good workability in a short time.

<Other Modifications>
In the windowed architectural panels 20A to 20D having the above-described configuration, a reinforcing structure as shown in Figure 10 may be added at a position away from the through-hole A, if necessary, particularly 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 panel 21 and a long second rib 440 that runs along the inner surface of the outer panel 22 .

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.

The second rib 440 is integrally formed and includes a flat base piece 441 that contacts the inner surface of the outer panel 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 panel 21.

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 intermediate rib 440 and the reinforcing piece 432 of the first intermediate rib 430 .

Therefore, with the reinforcing structure shown in Figure 10, the first center rib 430 and the second center 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.

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 polycarbonate plates and acrylic plates, and other translucent plate materials other than glass plates can also be used.

In addition, according to the above-mentioned embodiment, the windowed architectural panel of the present invention is configured as a door (sliding door), but this windowed architectural panel can also be applied to fittings such as sliding doors, folding doors, windows, shoji screens, partitions, shutter curtains, etc.

Furthermore, the present invention is not limited to the above-described embodiments, and modifications can be made as appropriate without departing from the spirit of the present invention.
