Description

  The invention according to the claims includes a concrete tide wall (including a waterproof wall for fresh water) provided with a transparent resin plate or a glass plate, and a tide wall for assembling a transparent resin plate or the like on the concrete tide wall. This is related to the parts set.

  In areas where there is a risk of inundation due to storm surges, floods, etc., it is widely practiced to build a tide wall in the sea or river to prevent water from entering. The tide wall is generally made of concrete, but concrete alone is not good for the landscape, and even when the water level rises, the state of the sea, rivers, etc. cannot be known through the tide wall. Therefore, in the following Patent Documents 1 and 2, a tide barrier using a transparent resin plate such as acrylic in part is proposed.

JP 2008-208681 A Japanese Patent No. 4134242

  If you install a transparent resin plate on the tide wall, you can see the sea, rivers and lakes from the land side, so it is not only beautiful, but also when the water level rises due to storm surges, floods, etc. Since it is easy to know the level of vigilance and prepare for evacuation, it is advantageous in terms of safety.

  Transparent resin plates such as acrylic resin and polycarbonate resin have the disadvantage of low hardness and weakness to heat. For this reason, the surface may not be clear due to scratches or partial deformation caused by being pressed by the fire of cigarettes, and the transparency may be lowered as a whole.

  The tide walls described in the above-mentioned Patent Documents 1 and 2 do not consider the countermeasure in such a case, and thus the transparency of the resin plate is inevitably lowered. After several years, it is difficult to clearly see the sea, rivers, etc. through the resin plate, and there is a possibility that the advantages relating to the landscape and safety are lost.

  The invention according to the claims of the present application is to construct a tide barrier that allows the resin plate to be easily replaced when the transparency of the transparent resin plate is reduced due to scratches on the surface, and so on. A set of parts for tide walls is provided. Even when a glass plate is used instead of the transparent resin plate, the surface may be scratched, cracked, or soiled, and the transparency may be lowered. Provide a tide wall and tide wall parts set that can be replaced in a similar manner.

The tide wall part set according to the invention is a tide wall part set for assembling a transparent resin plate (including a translucent one) to a concrete tide wall (including a waterproof wall),
・ The transparent resin plate,
-A grooved frame body into which the edge of the transparent resin plate (not necessarily the entire periphery) can be inserted;
・ Watertight packing between transparent resin plate and frame,
-A restraining means for restraining the edge of the transparent resin plate so as to be releasable inside the groove of the frame.
Transparent resin plates include polystyrene resin, polyvinyl chloride resin, acrylonitrile-styrene copolymer resin, methyl methacrylate-styrene copolymer resin, acrylonitrile-butadiene copolymer resin, thermoplastic resin selected from polycarbonate resin and acrylic resin, etc. Can be used. A metal such as steel (stainless steel, aluminum steel, etc.) may be used as the frame, and a plate rubber or the like may be used as the packing.

By using the parts set as described above, for example, as in the following 1) to 3), the transparent resin plate can be assembled to the concrete tide wall in a replaceable manner.
1) Open or cut out the tide wall concrete to the sea or river side and the land side, and attach the above frame to it. The frame may be fixed with bolts or the like inside the concrete openings or notches (in this case, a watertight member is also used between the frame and the concrete). You may make it embed in concrete (however, do not put concrete inside the groove).
2) A transparent resin plate is attached to the concrete opening or notch by inserting the edge of the transparent resin plate into the groove of the frame.
3) A watertight packing is attached between the transparent resin plate and the groove of the frame, and the edge of the resin plate is restrained and fixed inside the groove of the frame by the restraining means.
In place of the above 1) to 3), a transparent resin plate is previously incorporated into the frame together with packing and restraining means, and the above-mentioned component set thus completed is attached to the concrete of the tide wall, You can also take the following procedure.

As described above, the transparent resin plate can be assembled to the concrete tide barrier via the frame. Since the edge portion is restrained by the restraining means, the resin plate can be firmly fixed, and since the packing is attached as described above, the waterproof property around the resin plate can be secured. Since a transparent resin plate is provided on a concrete tide wall, as described above, it is preferable both in terms of landscape and safety. Since the resin plate is not directly attached to the concrete tide wall, excessive force acts on the resin plate during or after installation, and the resin plate is deformed or cracked. There is no fear. For example, since it is easy to make a slight gap (displacement) between the frame and the resin plate, the resin plate may be deformed or damaged even when the resin plate thermally expands in summer. It becomes difficult.
When the parts set of the invention is used, if the frame is appropriately configured, the assembled transparent resin plate can be taken out of the frame again by releasing the restraint by the restraining means. Further, another transparent resin plate can be inserted and fixed in the same frame as in the above 1) to 3). Therefore, according to the parts set of the invention, it becomes possible to replace the transparent resin plate, and even when the transparency of the resin plate is lowered due to a scratch on the surface, the transparency is restored and the landscape and safety advantages are maintained. Can do.

Preferably, the restraining means can change the dimension in the width direction of the groove between the inner surface of the groove of the frame and the edge of the transparent resin plate. For example, when a wedge is driven as a restraining means between the inner surface of the groove and the edge of the resin plate, the dimension in the width direction of the groove is changed as described above depending on the amount of driving. Can do. Even when a screw-type or hydraulic jack is inserted between the two or when a bag-shaped object filled with a fluid is sandwiched between the two, the dimension in the width direction of the groove for each of these restraining means Can be changed. In addition, close contact with a clip or the like is also possible.
When such a restraining means is used, the resin plate can be easily restrained by changing the dimension in the width direction of the groove and pressing the edge of the transparent resin plate inside the groove to apply a frictional force. Can be fixed. It is not necessary to make a hole, bond or weld the resin plate, and it is very easy to release the restraint.

In particular, the restraining means includes a screw member with a right screw and a screw member with a left screw at each screw portion of a nut member or bolt member having a right screw and a left screw (so-called reverse screw) at both ends. Each is preferably fitted (that is, screwed). For example, FIG.2 (b) is an example which uses such a restraining means. It can be said that the pushing member is coupled to the nut member and the bolt member in this manner is a simple manual type screw jack.
In such a restraining means, by rotating the nut member or the bolt member, it is easy to widen or narrow the distance between the two pushing members (that is, the dimension in the width direction of the groove) by the action of the screw. It is. Since it is composed of a nut member or bolt member and two extruded members with respective screws, the structure is simple and the cost is low. Since each of the push-out members can be prevented from rotating while the nut member or the bolt member is rotated, there is an advantage that the transparent resin plate and the frame body are not damaged.

In particular, the frame has a bottom portion and side portions that are continuous with each other at right angles so that a transparent resin plate can be inserted in which the lower side and the sides on both sides are at right angles to each other. However, it is also preferable to have a connection part with the support | pillar fixed on the concrete of a tide wall. For example, as shown in each example of FIGS. The support columns may be diagonal as shown in FIGS. 8 and 9 (reference numeral 12P) or vertical as shown in FIG. 10 (reference numeral 12Q). Further, the upper side of the transparent resin plate may be linear or curved, and in any case, a frame may or may not be provided on the upper side.
As shown in FIGS. 8 to 10, such a tide wall part set is arranged continuously at the top of a concrete tide wall to raise the height of the existing tide wall and A transparent resin plate can be provided in a replaceable manner. Since the frame is supported by the above-mentioned support columns, the ability to resist water pressure is also ensured.

The tide wall (including the waterproof wall) according to the invention is made of concrete, and the transparent resin plate is assembled in a replaceable manner by using any of the above tide wall part sets. Features.
Such a tide barrier is made of concrete and thus easily exhibits strength to withstand water pressure, and has a transparent resin plate, so that it is preferable in terms of landscape and safety. In other words, you can see the sea and river from the land side, and even when the water level rises due to flooding etc., you can grasp the state of the sea and river through the tide wall and easily prepare for evacuation.
Use of the above-mentioned tide barrier part assembly for assembly of the transparent resin plate is preferable in terms of fixing the resin plate, waterproofing the surrounding area, preventing deformation, cracking, etc., and replacing the assembled transparent resin plate. It becomes possible. If the replacement is possible, the landscape and safety advantages can be recovered even when the surface of the resin plate is damaged.

The transparent resin plate is a quadrilateral (having a horizontal upper side), and three sides except for the horizontal side of the upper side are attached to the concrete (concrete wall forming the tide wall) via the frame. A seawall is also preferred. For example, a tide barrier as shown in FIG. For one side that is the upper side, the frame is not used and attached to the concrete, or the frame is attached to the concrete even if the frame is used as in the example of FIG. So that it is not.
In such an example in which three sides are attached to concrete via a frame, it is inserted from above into a notch portion of the concrete wall that is open on the top (preferably a groove or the like for the frame is formed). The frame can be easily assembled in the manner described above. Also, if you do not use a frame for the upper side, or if you use a frame for the upper side but make the upper side frame separate from the frame on the other side, from the frame attached to the concrete, It is easy to extract the transparent resin plate for replacement or the like.
Note that the transparent resin plate is attached to the concrete wall in the same manner as described above even when the transparent resin plate is not a quadrilateral and the upper side is not linear. That is, the transparent resin plate has a shape in which the lower side and the sides on both sides thereof are perpendicular to each other (the upper side is an arbitrary shape including a curve), and the three sides excluding the upper side form the frame. It is good to make it attach to concrete via.

If the transparent resin plate has a cylindrical curved surface (for example, a curved surface forming a part of the cylindrical surface) with the land side (side opposite to the side close to the sea or river) convex and the axis centered horizontally Particularly preferred. For example, a tide barrier as shown in FIG.
If the transparent resin plate has a cylindrical curved surface, it has higher mechanical strength than a resin plate of the same material and the same thickness, and can easily withstand water pressure or the like. Therefore, even when the resin plate has a quadrilateral shape and the upper side is not attached to the concrete (thus, the upper side is not supported by the concrete), the resin plate has sufficient strength to resist storm surges and floods. Easy to do. At the same time, an improvement in aesthetics can be expected due to the transparent resin plate having a curved surface.
In addition, if the transparent resin plate with the land side convex is provided so that the upper side protrudes to the sea side as in the example of FIG. 4, and the concrete wall is formed so that the upper part also protrudes to the sea side, so-called wave return Can construct a structural tide barrier. By doing so, it is possible to effectively reduce the amount of overtopping.

The tide wall of the invention
・ The tide wall part set, which is formed by inserting the entire circumference of the transparent resin plate into the groove of the frame, is used inside the opening that is surrounded by concrete and penetrates in the thickness direction.
-The opening includes a large cross-sectional portion in which the frame of the component assembly can be fitted and a small cross-sectional portion in which the frame cannot be fitted, and a step (continuous step) is formed on the entire circumference at the boundary between the two portions. Having anchors with screw holes (female threads) embedded in the wall of the large cross-section part,
-It is also preferable that the tide wall part set is fixed in a state in which the opening is closed by pressing the frame body against the step using a fastener fixed to the anchor with a bolt.
Examples thereof are shown in FIGS. 11 and 13. The frame may be linear or curved along the shape of the edge of the transparent resin plate, and a plurality of pieces may be detachably connected in the length direction to constitute a set of frames.
Such a tide wall has the tide wall part set including the transparent resin plate in a state where the tide wall is pressed against the step in the opening of the concrete wall all around, so that the part set can be strongly held. . When the bolts are pulled out from the anchors and the fasteners are removed, protrusions can be eliminated from the large cross section of the opening. Therefore, the parts set is removed from the tide wall, the transparent resin plate is replaced, and the tide It can also be integrated into the wall. When the same part set is incorporated into the tide barrier, the fastener is fixed by a bolt screwed into the anchor, and the frame is pressed against the step with the fastener.

The tide wall of the invention, or
-The above frame body has a bottom portion and side portions on both sides continuous at right angles to each other so that a transparent resin plate can be inserted in which the lower side and the sides on both sides are perpendicular to each other. A tide wall part set having a configuration such as having a connecting portion with a pillar fixed on the concrete of the tide wall is used,
・ On the concrete of the tide wall, the bottom of the frame is fixed and the side of the frame is fixed through the support so that the transparent resin plate is assembled in a replaceable manner. It is also preferable.
For example, the tide barrier is configured as shown in any of FIGS. Such a tide wall has a transparent resin plate wall at the top of the concrete wall, so that the water level that can be tide protected is high, and the effect of the transparent resin plate is advantageous in terms of landscape and safety. Since the transparent resin plate can be replaced, such advantages can be made permanent. Since the bottom of the frame is fixed on the concrete and the side of the frame is fixed via the support column, the ability to resist water pressure is also high.
In this case as well, depending on the shape of the concrete tide wall, etc., it can be formed on the transparent resin plate as a cylindrical curved surface with the land side convex and the axis centered horizontally.

  The component set and the tide wall described above function in the same manner when the glass plate (including a tempered glass plate) is used instead of the above-described transparent resin plate, and bring similar advantages. The same applies when a transparent plate made by laminating a plurality of transparent resin plates or glass plates or a transparent plate having a reinforcing mesh (net) sandwiched between the laminated plates is used.

  According to the tide wall part set of the invention, since the tide wall including the transparent resin plate or the glass plate is included, the tide wall excellent in scenery and safety can be easily configured. Can be made difficult to be deformed or damaged. The assembled transparent resin plate or glass plate can be taken out from the frame and replaced, so even if the transparency of the resin plate or glass plate is reduced due to scratches on the surface, the transparency is restored and the tide is prevented. Can maintain landscape and safety benefits on the walls.

  The tide barrier of the invention includes a transparent resin plate or a glass plate, so that it is preferable in terms of landscape and safety. In addition, since the tide barrier part set described above is used, it can be said that the tide barrier provides the above advantages as it is. Since the assembled transparent resin plate and glass plate can be replaced, the advantages regarding landscape and safety are exhibited permanently.

FIG. 13 is a front view showing a tide wall constructed by providing the tide wall part set of FIG. 12 inside a concrete wall 2.

A first embodiment of the invention will be introduced based on FIGS.
A tide wall 1 shown in FIG. 1 and FIG. 2 has a concrete wall 2 continuous along a coast, and a transparent resin plate 11 is incorporated at a plurality of locations as shown in the figure. A rectangular notch with an open top is formed in the upper half of the concrete wall 2 at regular intervals, and a quadrilateral transparent resin plate 11 is assembled inside each notch. Since the sea can be seen from the land side through the transparent resin plate 11, it is excellent in scenery and also has an advantage in disaster prevention.

  The tide wall 1 of FIGS. 1 and 2 is assembled with a transparent resin plate 11 by using the tide wall component set 10 shown in FIG. The component set 10 includes a transparent resin plate 11 made of acrylic, a groove-shaped frame body 12 into which the edges of the three sides of the transparent resin plate 11 are inserted, and a groove-shaped frame into which the edge of the upper side of the transparent resin plate 11 is inserted. It is configured to be held by the frame 13.

  In addition to a) inserting the edge of the transparent resin plate 11 into the U-shaped grooves in the frame bodies 12 and 13, b) sealing between the resin plate 11 and the frame bodies 12 and 13 (watertight) At the same time, packing 19A and 19B made of rubber plates (which may be made of other materials as long as they have water tightness) are applied to the front and back surfaces of the transparent resin plate 11 so that local force is not applied to the resin plate 11. And insert as shown. Further, c) a restraining means 14 for restraining a plurality of locations at the edge of the transparent resin plate 11 so as to be releasable is inserted between one plate-like member of the groove. In addition, d) A cushion member 18 made of a rubber plate is also sandwiched between the end surface of the lower side of the resin plate 11 and the bottom of the frame body 12.

  The restraining means 14 is shown in FIG. 2 (b), and the screw member 16 of the nut member 15 having the right screw 16a and the left screw 17a at both ends is provided with the pushing member 16 with the right screw 16a and the left screw 17a. The push-out members 17 are respectively fitted. The extruding member 16 is fixed to the inner surface of the frame 12 (or 13) by welding or the like, and the extruding member 17 is a long body having a length along the frame 12 (or 13), and neither of them is rotated. I am doing so. When the nut member 15 is rotated with a spanner or the like, the distance between the two push-out members 16 and 17 widens or narrows to the left and right in FIG. For this reason, the restraining means 14 restrains the edge of the transparent resin plate 11 by pressing the edge of the transparent resin plate 11 inside the groove of the frame 12 (or 13), or releases the restraint. be able to.

In constructing the tide wall 1 of FIGS. 1 and 2 using the component set 10 described above, the following procedure is taken.
1) The frame 12 is embedded in the concrete at the notch in the concrete wall 2 of the tide wall 1. However, the concrete is prevented from entering the inside of the groove of the frame 12.
2) Insert the transparent resin plate 11 from above the frame body 12 so that the edges of the three sides other than the upper side fit into the groove of the frame body 12. A cushion material 18 is bonded in advance to the bottom surface of the lower side of the frame 12 that contacts the lower end surface of the resin plate 11. Further, a packing 19A is attached to the inner side of one portion forming the groove of the frame body 12, and the interval between the pushing members 16, 17 of the restraining means 14 is made as narrow as possible.
3) When the transparent resin plate 11 enters between the grooves of the frame 12, the nut member 15 of the restraining means 14 is turned to restrain and fix the edge of the resin plate 11 inside the frame 12. After that, the packing 19 </ b> B is pushed into between the resin plate 11 and one part of the frame body 12 (inside the restraining means 14).
4) Cover the frame 13 with the upper side of the attached transparent resin plate 11 and the upper end of the frame 12, attach a packing in the frame 13, and then use the restraining means 14 to attach the frame 13 and the resin plate. 11 is assembled together. This is because the upper side of the transparent resin plate 11 is protected by the frame 13.

  When the transparent resin plate 11 is taken out for replacement or the like, the upper frame body 13 assembled in 4) above is removed by loosening the restraining means 14, and the restraining means 14 in 3) relating to the frame body 12 is restrained. After releasing by operating, the resin plate 11 may be extracted upward, contrary to the above 2). When the transparent resin plate 11 whose surface is no longer clear is taken out in this way, and the new transparent resin plate 11 is assembled according to the procedures 2) to 4) above, the advantages of the tide wall 1 regarding the landscape and disaster prevention performance can be made permanent. it can.

  FIG. 4 shows a second embodiment of the invention. Also in this example, a tide wall 1 ′ having a transparent resin plate 21 on a part of a concrete wall 2 ′ is configured using a tide wall part set including parts similar to those in FIG. 3.

  However, in the example of FIG. 4, the transparent resin plate 21 has a curved surface along the surface of the concrete wall 2 ′ in accordance with the concave curved surface and the upper part protruding toward the sea. Is formed. That is, the transparent resin plate 21 has a cylindrical curved surface with the land side convex and the axis centered horizontally, and the upper portion protrudes to the sea side. Therefore, the tide wall part set includes the transparent resin plate 21 having the curved surface as described above and the frame bodies 22 and 23 having grooves along the curved surface together with the packing, cushioning material, and restraining means as described above. It is configured as follows.

  When the transparent resin plate has a cylindrical curved surface as described above, there are advantages in terms of strength against water pressure, and there is an effect that the overtopping amount can be reduced by the action of wave return.

  In the above, an example of incorporating a transparent resin plate or glass plate inside a concrete wall was introduced. However, a transparent resin plate or glass plate can also be assembled so as to be raised at the top of a new or existing tide wall. . For that purpose, the frame body of the tide wall part set according to the invention may be continuously arranged and fixed on the upper end surface of the tide wall.

  FIG. 5 shows a tide wall part set 10 that can be used in place of the tide wall part set shown in FIG. 3. In this example, unlike the one in FIG. 3, a frame is not attached to the edge that is the upper side of the transparent resin plate 11. Further, packing (rubber plate) is symmetrically provided on both surfaces of the edge of the transparent resin plate 11, that is, between the resin plate 11 and the frame 12 and between the resin plate 11 and the restraining means 14 shown in FIG. 19A is arranged. A portion between the transparent resin plate 11 and the frame 12 and visible from the transparent resin plate 11 side (a portion where rainwater or the like tends to enter) is covered with a sealing material 19C.

  The component set 10 of FIG. 5 can be attached to the concrete wall 2 as shown in FIG. 6, and can be a part of the tide wall. The tide wall shown in FIG. 6 has substantially the same configuration as the tide walls shown in FIGS. 1 and 2, but the upper side of the transparent resin plate 11 is open without being attached with a frame. The upper end of the frame 12 that continues from the lower side to the side is covered with a cap 12e (another plate may be placed on the upper side and fastened with a bolt or the like) to prevent rainwater from entering. The upper surface of the sealing filler 19C may be further covered with an acrylic plate 19D to improve the appearance as shown in FIG. 6C.

  As shown in FIG. 4, when the transparent resin plate is incorporated into the concrete wall 2 ′ whose sea side surface is curved concavely and the upper part protrudes to the sea side, no frame is provided on the upper side as shown in FIG. When using a set of parts, the tide wall is constructed so that the cross section is as shown in FIG. In this case, it is preferable to use a transparent resin plate 21 having a cylindrical curved surface in which the land side is convex and the axis is horizontal in accordance with the cross-sectional shape of the concrete wall 2 ′. Since the curved transparent resin plate 21 is advantageous in strength, the curved transparent resin plate 21 is strong against water pressure and can also exhibit a wave-returning action.

The tide barrier shown in FIGS. 8 to 10 has a structure in which a transparent resin plate is disposed so as to be raised above an existing concrete wall.
First, in the example of FIG. 8, each edge of the four sides of the rectangular transparent resin plate 11 is inserted into the frame 12 (groove) extending over the entire circumference including the bottom portion 12 a, the side portion 12 b, and the upper portion 13. 12 is fixed to the concrete wall 2, and the side portion 12 b is fixed to the concrete wall 2 through oblique pillars 12 </ b> P provided integrally. The fixing to the concrete wall 2 is performed by integrating the base plate 12f with the bottom portion 12a and the lower end portion of the support 12P, and fastening the base plate 12f to the foundation bolt 12g embedded in the concrete wall 2. Between the frame bodies 12 (side portions 12b) in the adjacent parts set, a packing (rubber plate) 19E for watertightness is sandwiched, and fillers 19F are packed on both sides thereof.

  9 uses a frame body 12 having only a bottom portion 12a and side portions 12b on both sides of the rectangular transparent resin plate 11, and the upper side of the transparent resin plate 11 is opened without providing a frame body. doing. And the bottom part 12a of the frame 12 is fixed to the concrete wall 2 as well, and the side part 12b is fixed to the concrete wall 2 via the oblique support 12P provided integrally. The point which uses the base board 12f and the foundation bolt 12g is the same as the example of FIG.

  10, the tide barrier of FIG. 10 inserts each edge of the four sides of the rectangular transparent resin plate 11 into the frame body 12 including the bottom portion 12a, the side portion 12b, and the upper portion 13, and the frame body. 12 is fixed on the concrete wall 2. Although the bottom part 12a of the frame 12 is fixed to the concrete wall 2 and the side part 12b is fixed to the concrete wall 2 via the pillars 12Q provided integrally, the pillars 12Q in this example are the same as in FIG. Stands vertically on the concrete wall 2. As shown in FIG. 10 (b), the support column 12Q has a T-shaped cross-sectional shape, and overhanging pieces 12h provided integrally along the side portion 12b of the frame body 12 with respect to the flange portions on both sides are packed. 19G is joined with scissor bolts 12i.

In FIG. 11, the example which provides the transparent resin board 11 grade | etc., With respect to the opening 3 provided like the window in the middle of the concrete wall 2 is shown. That is, the opening 3 is surrounded by concrete and penetrates in the thickness direction, and the component set 10 including the transparent resin plate 11 is provided in the opening 3. As the component set 10, one in which the entire periphery of the edge of the transparent resin plate 11 is inserted into the groove of the frame body 12 (including packing and restraining means) is used.
In this example, the opening 3 is formed by continuously connecting a large cross-sectional portion 3a into which the frame body 12 of the component set 10 can be fitted and a small cross-sectional portion 3b into which the frame body 12 cannot be fitted on the same center line. In addition, a step (surface perpendicular to the center line) 3c that is continuous over the entire circumference is provided on the wall surface of the boundary between both portions 3a and 3b. A plurality of anchors 4 with screw holes (female screws) are embedded on the wall surface of the large cross section 3a at intervals in the circumferential direction.
The part set 10 is assembled with the transparent resin plate 11 to the frame body 12 and the like, and is fitted into the opening 3 from the large cross section 3a side, and is pushed into the step 3c with the packing 19H sandwiched as shown in FIG. 11 (c). Hit it. After the opening 3 is closed by attaching the component set 10 in this manner, the fastener 6 is fixed to the anchor 4 provided on the large cross-section portion 3a by the bolt 5, and the frame body is provided by the extrusion bolt 6a provided thereon. The end face of 12 is pressed toward the step 3c.
As described above, the part set 10 is held in the opening 3 in a state where the entire circumference of the frame body 12 is pressed against the step 3c via the packing 19H, and can be taken out again.

  FIG. 12 shows a circular tide wall part set 30 in place of the part set 10 of FIG. 3 or FIG. Since the transparent resin plate 31 has a circular shape (disc shape), the frame body 32 attached to the edge of the transparent resin plate 31 is also used by connecting each piece that draws an arc of 90 ° so that the frame body 32 is circular as a whole. .
