  Hereinafter, a frame structure of a translucent panel and a method of attaching and detaching the translucent panel according to the embodiment of the present invention will be described in detail with reference to the drawings.

[First Embodiment]
First, the frame structure of the translucent panel according to the first embodiment of the present invention will be described with reference to FIGS. The light transmitting panel 1 according to the first embodiment is of a type in which the light transmitting plate is made of inorganic glass.

  FIG. 1 is a front view showing the translucent panel according to the first embodiment, FIG. 2 is a plan view thereof, and FIG. 3 is a right side view. FIG. 4 is a sectional view taken along line AA of FIG. 1, and FIG. 5 is a sectional view taken along line BB of FIG. Here, the front refers to a state that is viewed vertically and horizontally with respect to the plate surface of the translucent plate when viewed from the road or railroad side (hereinafter referred to as the inside) that is the source of noise.

  As shown in FIGS. 1 to 5, the light-transmitting panel 1 according to the present embodiment mainly includes a light-transmitting plate G <b> 1 and a panel frame 2 which is a frame in which the light-transmitting plate G <b> 1 is fitted. ing. The translucent panel 1 is attached to a pillar H1 (see FIG. 7) erected along a road or a railroad, and is used as a sound insulation wall for preventing propagation of noise generated from a vehicle such as an automobile or a train. In the light-transmitting panel 1, the light-transmitting plate G1 has a light-transmitting property, and the other side of the wall (generally, the private side, hereinafter referred to as the outside) is visible when viewed from the inside.

<Transparent plate>
The translucent plate G1 according to the first embodiment is made of chemically strengthened laminated glass in which a resin film is interposed between chemically strengthened glass whose glass surface is strengthened by a chemical treatment. Of course, the light-transmitting plate G1 can also be a plate glass made of chemical strengthened glass alone or general float glass.

  In short, the light-transmitting plate G1 may be a rectangular plate material at least whose surface is made of a light-transmitting inorganic glass such as quartz glass. When the surface is made of inorganic glass such as chemically strengthened glass, there is a merit that smoothness is high and visibility is high as compared with resin glass such as polycarbonate. In addition, as compared with resin glass, inorganic glass has higher chemical resistance, is less likely to be damaged, and has the advantages of extremely good weather resistance.

  However, inorganic glass is disadvantageous in that it is heavier than resin glass and has low impact resistance. For this reason, as described later, the translucent plate G1 is sealed with a silicone resin or the like, and an elastic body is interposed between the translucent plate G1 and the panel frame 2 so that the impact is not directly transmitted.

<< Panel frame >>
The panel frame 2 is an anodized aluminum frame made of an extruded aluminum alloy. As shown in FIGS. 1 to 5, a pair of upper and lower horizontal frames 3 and 3 and a pair of left and right linear symmetry are provided. It is composed of vertical frames 5, 5, and the like.

  As shown in FIGS. 3 and 4, wire stoppers 6 for inserting fall prevention wires W (see FIG. 10) are provided at two upper and lower positions in the vertical frames 5 and 5 of the panel frame 2. Have been.

<Horizontal frame>
FIG. 6 is an enlarged end view of the portion C in FIG. 5 mainly showing the horizontal frame 3 of the translucent panel 1. As shown in FIG. 6, the horizontal frame 3 is composed of a frame body 30 whose vertical cross section is a substantially rectangular strip, and a light-transmitting plate G1 is mounted on the lower side of the frame body 30 near the inside. A groove 31 is formed.

  A gasket mounting groove 32 for mounting a gasket Ge is formed on the outer side surface of the light transmitting plate mounting groove 31. The gasket Ge is made of a rubber elastic body such as a silicone resin.

  The gasket Ge is mounted in the gasket mounting groove 32, and the upper end (or lower end) of the light transmitting plate G1 is inserted into the light transmitting plate mounting groove 31 with the plate surface of the light transmitting plate G1 abutting the gasket Ge. Have been. Further, the light transmitting plate G1 is mounted in the light transmitting plate mounting groove 31 by being sealed (sealed) along the inner edge of the light transmitting plate G1 with the sealant S1. The sealing material S1 is made of a rubber elastic body such as a silicone resin or a modified silicone resin.

  For this reason, the translucent plate G1 is elastically supported by being sandwiched between the two rubber elastic bodies of the outer gasket Ge and the inner sealant S1, thereby compensating for the disadvantage of the translucent plate G1 having low impact resistance. Can be. Further, when the light transmitting plate G1 is replaced, the sealing material S1 is reconstructed only on the inside, so that it is not necessary to provide a temporary scaffold or the like on the outside.

  Reference symbol P1 denotes a backup material P1 that prevents the sealing material S1 in a fluidized state before being cured from entering the interior of the light transmitting plate mounting groove 31 when the sealing material S1 is applied. This backup material P1 is made of an easily deformable foamed resin.

  Further, from the viewpoint of sharing parts with the translucent panel 1 ′ according to the second embodiment described later, the horizontal frame 3 can be fitted (can be fitted) with a pressing edge 36 (see FIGS. 14 and 15) described later. It has a configuration. Specifically, in the horizontal frame 3, two ridge locking grooves 33 and 34 for locking the ridge 36 are formed inside the deep portion (upper or lower) of the light transmitting plate mounting groove 31. A tapered surface 35 for swingingly fitting the pressing edge 36 is formed on the outside thereof.

<Vertical frame>
FIG. 7 is an enlarged end view of a portion D in FIG. 4 mainly showing a mounting structure of the vertical frame 5 of the translucent panel 1. FIG. 8 is an exploded view of the vertical frame 5 disassembled into an inner frame 50 and an outer frame 51. It is an end elevation. As shown in FIGS. 7 and 8, the vertical frame 5 includes an inner frame 50 (front stop part) fixed inside the inner flange H <b> 1 a of the column H <b> 1 indicated by a dashed line, and is attached outside the inner frame 50. It is composed of two parts (members) of an outer frame 51 (rearranged parts).

  For this reason, if the inner frame 50 is changed, it is possible not only to cope with various fixing methods to the columns, but also to make the portion of the outer frame 51 common. For this reason, it is not necessary to design or manufacture a mold every time the fixing method is different, and the cost can be reduced.

(Inner frame)
Further, as shown in FIGS. 7 and 8, the inner frame 50 has a fastening plate 50a which is bolted to the column H1 and has a straight horizontal cross section. A fitting piece 50b having an L-shaped cross section is provided on the rear surface of the fastening plate 50a so as to project outward.

  The fitting piece 50b has a flange portion 50c extending in the panel surface direction of the translucent panel 1 from the middle (parallel to the fastening plate 50a and the inner flange H1a of the support H1; hereinafter, simply referred to as the panel surface direction). Are formed so that they go wild in a step with the back surface of the fitting piece 50b. In the vicinity of the end of the fastening plate 50a and the base end of the fitting piece 50b, a protruding piece 50d extending in the panel surface is formed so as to run in a step with the front of the fastening plate 50a. I have. The protruding piece 50d faces a gasket mounting groove 51c described later, and a space therebetween serves as a groove for fitting the light transmitting plate G1. That is, the protruding piece 50d forms an inner wall of a groove for fitting the light transmitting plate G1.

  A screw hole 50e having a C-shaped cross section for screwing the vertical frame 5 to the horizontal frame 3 is formed inside the vicinity of the joint between the fitting piece 50b and the flange portion 50c.

  In addition, the inner frame 50 has a configuration in which a later-described pressing edge 52 (see FIGS. 13 and 16) can be mounted from the viewpoint of sharing parts with a translucent panel 1 ′ according to a second embodiment described later. I have. Specifically, in the inner frame 50, two ridge lock grooves 50f and 50g for locking the ridge 52 are formed on the side of the translucent plate G1 of the protrusion 50d, and the ridge lock groove. On the 50g side, a tapered surface 50h for rockingly fitting the pressing edge 52 is formed.

(Outer frame)
As shown in FIGS. 7 and 8, the outer frame 51 has a rectangular closed section 51 a that is surrounded and closed, and an opening that is adjacent to the closed section 51 a in the in-plane direction and has the support H1 side opened. A part 51b. The open portion 51b is surrounded by a later-described flange portion 51e and a shielding portion 51g, which are provided on the front and rear surfaces of the closing portion 51a, and serves as a space through which a later-described fall prevention wire W is inserted. In addition, the open portion 51b can be used as a space for accommodating an extra length of the fall prevention wire W.

  A gasket mounting groove 51c for mounting the gasket Ge is formed inside the closed portion 51a. A fitting groove 51d is formed at a position adjacent to the gasket mounting groove 51c in the in-plane direction to fit with the fitting piece 50b having the L-shaped cross section.

  A flange portion 51e is formed at a position adjacent to the fitting groove 51d so as to extend in the panel surface inward so as to contact the flange portion 50c of the inner frame 50. Further, as shown in FIG. 7, the flange portion 50 c of the inner frame 50 and the flange portion 51 e of the outer frame 51 are bolted by wire fasteners 6. Of course, the flange portion 50c and the flange portion 51e may be bolted with other bolts instead of the wire stopper 6.

  As shown in FIG. 8, two screw holes 51f having a C-shaped cross section for screwing the vertical frame 5 to the horizontal frame 3 are provided near the two corners on the light transmitting plate G1 side among the four corners of the closing portion 51a. , 51f are formed.

  Further, the shielding portion 51g, which is a plate-shaped portion in which the outer surface of the closing portion 51a extends toward the support H1, shields the wire stopper 6 penetrating both the flange portions 50c and 51e from the outside. It has the function to do. For this reason, since it becomes invisible from the outside, the landscape is further improved.

  FIG. 9 is an explanatory view showing a situation where the inner frame 50 and the outer frame 51 are rotationally fitted. As shown in FIG. 9, the fitting of the inner frame 50 and the outer frame 51 is performed by inserting a fitting piece 50 b having an L-shaped cross section of the inner frame 50 into the fitting groove 51 d of the outer frame 51 in the direction of the arrow in the figure. The flange portion 50c and the flange portion 51e are rotated and fitted until they come into contact with each other. In other words, in other words, the inner frame 50 and the outer frame 51 are structured so that the fitting between the inner frame 50 and the outer frame 51 cannot be released unless they are separately rotated as described above. For this reason, even if the vertical frame 5 is divided into two, it is possible to prevent a large accident in which each member falls off.

Further, since the inner frame 50 has a fitting piece 50b protruding outward and the outer frame 51 has a fitting groove 51d fitted with the fitting piece 50b, the fitting piece is fitted into the fitting groove 51d. When the flange portions 50c and 51e are bolted together with the 50b fitted, they can be easily fixed.
Although not shown, a fitting groove 51d 'is provided in the inner frame 50, and a fitting piece 50b' is provided in the outer frame 51. The fitting groove 51d 'of the inner frame 50 has an L-shaped cross section of the outer frame 51. The fitting piece 50b 'may be inserted and rotated from the outside to the inside until the flange portion 50c and the flange portion 51e come into contact with each other to be fitted.

  Then, as shown in FIG. 7, the inner frame 50 and the outer frame 51 are fitted to each other, and are bolted by the wire stopper 6 penetrating through both the flange portions 50c and 51e. In addition, the vertical frame 5 is screwed to the horizontal frame 3 with screws S at the screw holes 50e and 51f of the inner frame 50 and the outer frame 51 (see also FIG. 3). Of course, it may be screwed and fixed with a bolt or the like instead of the screw S.

  For this reason, the possibility that the inner frame 50 and the outer frame 51 may fall off the horizontal frame 3 can be eliminated. Therefore, it is possible to prevent a large accident in which parts of the light-transmitting panel 1 drop from a viaduct of a road or a railway and damage people or vehicles passing below, thereby improving safety. I do.

<Wire clamp>
FIG. 10 is a perspective view showing a state in which the fall prevention wire W is inserted through the wire stopper 6 of the translucent panel 1. As shown in FIG. 10, the wire stopper 6 is a member formed by bending a steel rod (steel wire) as a wire, has a spiral wire insertion portion 60 having one open end, and has a wire end portion at the other end. The screw fitting is a spiral fitting to which a nut can be screwed.

  The wire stopper 6 is used for inserting the fall prevention wire W into the wire insertion portion 60 and connecting the light transmitting panels 1 to each other in the vertical direction. For this reason, the wire stopper 6 prevents the translucent panel 1 from dropping from the column H1 even if the connecting member such as a bolt for fixing the translucent panel 1 to the column H1 is broken due to an accident or the like. It has a function to prevent it.

  Although the spiral metal fitting having the spiral wire insertion portion 60 has been illustrated as the wire stopper 6 according to the present embodiment, a general eyebolt may be used. Even in that case, it is possible to connect the translucent panels 1 vertically by inserting the fall prevention wire W into the eyebolt. However, as will be described later, when the wire stopper 6 is a spiral fitting, the translucent panel 1 in the middle can be replaced while the translucent panels 1 are vertically connected by the fall prevention wire W. Is preferable.

<Transparent plate removal procedure>
Next, a procedure for removing the light transmitting plate G1 from the panel frame 2 of the light transmitting panel 1 when the light transmitting plate G1 is replaced for repair or the like will be described with reference to FIG. FIG. 11 is an explanatory diagram illustrating a procedure for removing the light transmitting plate G1 from the panel frame 2 of the light transmitting panel 1, and is performed in the order of (a) to (d). As shown in FIG. 11, when removing the light-transmitting plate G1 from the panel frame 2, the light-transmitting plate G1 is temporarily lifted in a Kendon manner, and the lower end is swung to be removed.

  Specifically, as shown in FIG. 11A, first, the seal members S1 and the like on the four sides of the light transmitting plate G1 are removed. Then, as shown in FIG. 11B, the light transmitting plate G1 is lifted up to the upper end of the light transmitting plate mounting groove 31, and the lower end of the light transmitting plate G1 is disengaged from the light transmitting plate mounting groove 31 of the lower horizontal frame 3. To a free state.

  Next, as shown in FIG. 11 (c), the lower part of the light transmitting plate G1 is pulled forward (inward) to swing the light transmitting plate G1 in the vertical rotation, and the upper end of the light transmitting plate G1 is moved to the upper side. It swings until it abuts in the mounting groove 31 and stops rotating. Then, as shown in FIG. 11 (d), the light transmitting plate G 1 is lowered from that state, the upper end of the light transmitting plate G 1 is pulled out from the light transmitting plate mounting groove 31, and the light transmitting plate G 1 is removed from the panel frame 2. .

  As described above, in the light transmitting panel 1, only the light transmitting plate G1 can be replaced without disassembling the panel frame 2. Therefore, even when the light transmitting plate G1 is damaged by a stepping stone or the like, the light transmitting plate G1 can be easily replaced in a short time. Therefore, the work time of the maintenance work can be significantly reduced.

  According to the frame structure of the translucent panel 1 according to the first embodiment described above, since the vertical frame 5 is divided into two parts, the inner frame 50 and the outer frame 51, the inner frame 50 fixed to the support H1 or the like is provided. By changing it, it is possible to cope with various fixing methods to the support. In addition, this allows the outer frame 51 to be shared, eliminating the need to manufacture designs and molds for different fixing methods, thereby achieving cost reduction.

  In addition, according to the frame structure of the translucent panel 1 according to the first embodiment, since the vertical frame 5 can be divided into two, the maximum diameter of each part can be made smaller than the maximum diameter of the conventional vertical frame. It is possible to reduce the size of the extrusion mold. Therefore, also in that respect, the manufacturing cost can be reduced and the cost can be reduced.
