Hereinafter, the frame structure of the translucent panel and the 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. 1 to 10. The translucent panel 1 according to the first embodiment is of a type in which the translucent plate is made of inorganic glass.

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

As shown in FIGS. 1 to 5, the translucent panel 1 according to the present embodiment is mainly composed of a translucent plate G1 and a panel frame 2 which is a frame body into which the translucent plate G1 is fitted. ing. The translucent panel 1 is attached to a support column H1 (see FIG. 7) erected along a road or a railroad, and is used as a sound insulation wall for preventing the propagation of noise generated from a vehicle such as an automobile or a train. Further, in the translucent panel 1, the translucent plate G1 has translucency, and the other side of the wall (generally the private land side, hereinafter referred to as the outside) can be visually recognized when viewed from the inside.

<Translucent 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 glasses whose glass surface is strengthened by chemical treatment. Of course, the translucent plate G1 can also be a plate glass made of a single chemically strengthened glass or general float glass.

In short, the translucent plate G1 may be a rectangular plate material whose surface is at least made of translucent inorganic glass such as quartz glass. This is because by using an inorganic glass such as chemically tempered glass for the surface, there is an advantage that the smoothness is high and the visibility is high as compared with the resin glass such as polycarbonate. Inorganic glass also has the advantages of higher chemical resistance, less scratches, and extremely good weather resistance than resin glass.

However, inorganic glass has the disadvantages that it is heavier than resin glass and has low impact resistance. Therefore, as will be described later, the translucent plate G1 is sealed with a silicon resin or the like and is supported by interposing an elastic body 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 a frame made of alumite made of an extruded aluminum alloy, and 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 horizontal frames are line symmetric. It is composed of vertical frames 5, 5, and the like.

FIG. 6 is an enlarged end view of the C portion of FIG. 5, which mainly shows the horizontal frame 3 of the translucent panel 1. As shown in FIG. 6, the horizontal frame 3 is composed of a frame main body 30 whose vertical cross section is a strip having a substantially rectangular cross section, and a light transmissive plate G1 is mounted on the inner side of the lower portion of the frame main body 30. A groove 31 is formed.

Further, a gasket mounting groove 32 for mounting the gasket Ge is formed on the outer side surface of the translucent plate mounting groove 31. This gasket Ge is made of a rubber elastic body such as silicon resin.

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

Therefore, the translucent plate G1 is sandwiched between the two rubber elastic bodies of the outer gasket Ge and the inner sealing material S1 and elastically supported, thereby compensating for the drawback of the translucent plate G1 having low impact resistance. Can be done. Further, when the translucent plate G1 is replaced, the sealing material S1 is reconstructed only on the inner side, so that it is not necessary to provide a temporary scaffolding or the like on the outer side.

Reference numeral P1 is a backup material P1 that prevents the sealing material S1 in a flowing state before curing from entering the depth of the translucent plate mounting groove 31 when the sealing material S1 is applied. The backup material P1 is made of a foamed resin that is easily deformed.

Further, from the viewpoint of sharing the parts with the translucent panel 1'according to the second embodiment described later, the horizontal frame 3 can be fitted (attachable) to the ridge 36 (see FIGS. 14 and 15) described later. It is composed. Specifically, in the horizontal frame 3, two ridge locking grooves 33, 34 for locking the ridge 36 are formed inside the inner portion (upper or lower) of the translucent plate mounting groove 31. On the outside thereof, a tapered surface 35 for swinging and fitting the ridge 36 is formed.

<Vertical frame>
FIG. 7 is an enlarged end view of the D portion of FIG. 4, which mainly shows the mounting structure of the vertical frame 5 of the translucent panel 1, and FIG. 8 is an exploded view of the vertical frame 5 divided into an inner frame 50 and an outer frame 51. It is an end view. As shown in FIGS. 7 and 8, the vertical frame 5 is attached to the inner frame 50 (front stop part) fixed to the inside of the inner flange H1a of the support column H1 indicated by the alternate long and short dash line, and to the outside of the inner frame 50. It is composed of two parts (members) of the outer frame 51 (retrofitting part) to be formed.

Therefore, if the inner frame 50 is changed, not only can it correspond to various fixing methods to the columns, but also the portion of the outer frame 51 can be made common. Therefore, it is not necessary to design or manufacture a mold each time the fixing method is different, and cost reduction can be achieved.

(Inner frame)
Further, as shown in FIGS. 7 and 8, the inner frame 50 has a fixing plate 50a having a linear horizontal cross section bolted to the support column H1. On the back surface of the fixing plate 50a, a fitting piece 50b having an L-shaped cross section is projected outward.

Then, the fitting piece 50b has a flange portion 50c extending in the panel surface inward direction of the translucent panel 1 (parallel to the inner flange H1a of the fixing plate 50a and the support column H1, hereinafter simply referred to as the panel inward direction). Is formed so as to stagger from the back surface of the fitting piece 50b. Further, in the vicinity of the end portion of the fastening plate 50a and the base end portion of the fitting piece 50b, a projecting piece 50d extending inward of the panel surface is formed so as to stagger from the front surface of the fastening plate 50a. There is. The projecting piece 50d faces the gasket mounting groove 51c described later, and the space between them is a groove for fitting the translucent plate G1. That is, the projecting piece 50d constitutes the inner wall of the groove for fitting the translucent 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 portion between the fitting piece 50b and the flange portion 50c.

In addition, the inner frame 50 has a configuration in which the ridge 52 (see FIGS. 13 and 16) described later can be mounted from the viewpoint of sharing the parts with the translucent panel 1'according to the second embodiment described later. There is. Specifically, in the inner frame 50, two ridge locking grooves 50f and 50g for locking the ridge 52 are formed on the translucent plate G1 side of the projecting piece 50d, and the ridge locking groove is formed. A tapered surface 50h for rocking and fitting the ridge 52 is formed on the 50g side.

(Outer frame)
As shown in FIGS. 7 and 8, the outer frame 51 has a closed portion 51a having a rectangular cross section surrounded and closed, and an open portion in which the support column H1 side is opened adjacent to the closed portion 51a in the in-plane direction. A section 51b and the like are provided. The open portion 51b is surrounded by a flange portion 51e, which will be described later, and a shielding portion 51g, which are extended on the front and rear surfaces of the closing portion 51a, and is a space for inserting the fall prevention wire W, which will be described later. Further, the open portion 51b can also be used as a space for accommodating the extra length of the fall prevention wire W.

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

A flange portion 51e extending inward of the panel surface is formed at a position adjacent to the fitting groove 51d so as to abut with the flange portion 50c of the inner frame 50. Further, as shown in FIG. 7, the flange portion 50c of the inner frame 50 and the flange portion 51e of the outer frame 51 are bolted to each other by a wire fixing metal fitting 6. Of course, the flange portion 50c and the flange portion 51e may be bolted with other bolts instead of the wire fixing metal fitting 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 near the two corners on the translucent plate G1 side among the four corners of the closed portion 51a. , 51f are formed.

Further, the shielding portion 51g, which is a plate-shaped portion whose outer surface of the closing portion 51a extends toward the support column H1, shields the wire stopper 6 penetrating the flange portions of both the flange portion 50c and the flange portion 51e from the outside. Has the function of For this reason, it cannot be seen from the outside, and the landscape is further improved.

FIG. 9 is an explanatory diagram showing a situation in which the inner frame 50 and the outer frame 51 are rotationally fitted. As shown in FIG. 9, the inner frame 50 and the outer frame 51 are fitted by inserting the fitting piece 50b having an L-shaped cross section of the inner frame 50 into the fitting groove 51d 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. That is, in other words, the structure is such that the inner frame 50 and the outer frame 51 are not released from being fitted to each other unless the inner frame 50 and the outer frame 51 are rotated separately in this way. Therefore, even if the vertical frame 5 is divided into two, it is possible to prevent a serious accident in which each member falls off.

Further, since the inner frame 50 has a fitting piece 50b projecting outward and the outer frame 51 has a fitting groove 51d for fitting with the fitting piece 50b, the fitting piece is fitted in the fitting groove 51d. The flange portions 50c and 51e can be easily fixed when bolting the flange portions 50c and 51e in a state where the 50b is fitted.
Although not shown, the inner frame 50 is provided with a fitting groove 51d'and the outer frame 51 is provided with a fitting piece 50b', and 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 bolted to each other with the wire fixing metal fittings 6 penetrating the flange portions 50c and 51e in a fitted state. 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 fixed by screwing with a bolt or the like instead of the screw S.

Therefore, it is possible to eliminate the possibility that the inner frame 50 and the outer frame 51 will fall off from the horizontal frame 3, respectively. Therefore, it is possible to prevent a major accident in which the parts of the translucent panel 1 fall from the viaduct of the road or railway and damage people or vehicles passing below due to the accident, and the safety is further improved. do.

<Wire stopper>
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 bent from a steel rod (steel wire) which is a wire rod, has a spiral wire insertion portion 60 having one end open, and has a spiral wire insertion portion 60 at the other end. A thread groove is formed to form a spiral metal fitting to which a nut can be screwed.

The wire stopper 6 is used to connect the translucent panels 1 to each other in the vertical direction by inserting the fall prevention wire W into the wire insertion portion 60. Therefore, the wire stopper 6 prevents the translucent panel 1 from falling from the strut H1 even if the connecting member such as a bolt that fastens the translucent panel 1 to the strut H1 is damaged by an accident or the like. It has a function to prevent it.

As the wire stopper 6 according to the present embodiment, a spiral metal fitting having a spiral wire insertion portion 60 is exemplified, but a general eyebolt may be used. Even in that case, it is possible to connect the translucent panels 1 to each other by inserting the fall prevention wire W through the eyebolt. However, as described later, it is better to use the wire stopper 6 as a spiral metal fitting so that the translucent panel 1 in the middle can be replaced while the translucent panels 1 are vertically connected to each other by the fall prevention wire W. It is preferable because it becomes.

<Procedure for removing the translucent plate>
Next, with reference to FIG. 11, a procedure for removing the translucent plate G1 from the panel frame 2 in the translucent panel 1 when the translucent plate G1 is replaced by repair or the like will be described. 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 the translucent plate G1 is removed from the panel frame 2, the translucent plate G1 is once lifted in a Kendon manner and the lower end is swung to remove it.

Specifically, as shown in FIG. 11A, first, the sealing material S1 and the like on the four circumferences of the translucent plate G1 are removed. Then, as shown in FIG. 11B, the light transmitting plate G1 is lifted 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.

It swings in the mounting groove 31 until it abuts and stops rotating. Then, as shown in FIG. 11D, the translucent plate G1 is lowered downward from that state, the upper end of the translucent plate G1 is pulled out from the translucent plate mounting groove 31, and the translucent plate G1 is removed from the panel frame 2. ..

In this way, the translucent panel 1 can replace only the translucent plate G1 without disassembling the panel frame 2. Therefore, even if the translucent plate G1 is damaged by flying stones or the like, the translucent plate G1 can be easily replaced in a short time. Therefore, the work time of the maintenance work can be significantly shortened.

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, an inner frame 50 and an outer frame 51, the inner frame 50 to be fixed to the support column H1 or the like is provided. If it is changed, it can correspond to various fixing methods to the support. Further, by this, the outer frame 51 can be made common, and it is not necessary to manufacture a design or a mold each time the fixing method is different, and cost reduction can be achieved.

Moreover, according to the frame structure of the translucent panel 1 according to the first embodiment, the vertical frame 5 can be divided into two, so that the maximum diameter of each part can be made smaller than the maximum diameter of the conventional vertical frame. The die for extrusion molding can be made smaller. Therefore, in that respect as well, the production cost can be reduced and the cost can be reduced.

Further, according to the frame structure of the translucent panel 1 according to the first embodiment, the inner frame 50 and the outer frame 51 are bolted to each other with the wire fixing metal fitting 6 in a fitted state, and the inner frame 50 and the outer side are fixed. The vertical frame 5 is screwed to the horizontal frame 3 at the screw holes 50e and 51f of the frame 51. Therefore, even if a strong impact load is applied to the translucent panel 1 due to an accident or the like, there is no possibility that the inner frame 50 and the outer frame 51 will fall off. For this reason, it is possible to prevent a major accident in which a part of the translucent panel 1 falls from a viaduct of a road or a railway and damages a person or a vehicle passing below due to an accident, and safety is improved. do.

In addition, according to the frame structure of the translucent panel 1 according to the first embodiment, the projecting pieces 50d forming the inner wall of the groove into which the translucent plate G1 is fitted are formed in the inner frame 50 along the inward direction of the panel surface. ing. Therefore, it is possible to seal (caulk) the periphery of the translucent plate G1 along the vertical frame 5 with the sealing material S1 to cope with the translucent plate G1 which is an inorganic glass that is vulnerable to impact.
