Description

The present invention relates to a lower frame structure of a light-transmissive panel that is installed along a road or a railroad and that has a light-transmitting property and that allows the outside to be visually recognized while preventing the propagation of noise. The present invention relates to a lower frame structure of a translucent panel that can prevent an accident that a melted substance flows out of the frame even when the translucent panel is burned and melted.

BACKGROUND ART Conventionally, a sound insulation wall has been installed which is installed along a road or a railroad and which prevents propagation of noise generated from vehicles such as automobiles and trains. In addition, such a sound insulation wall is also known as a sound insulation wall in which a translucent panel having translucency such as resin glass or inorganic glass is fitted in order to make the outside visible from the inside of a wall on which a vehicle or the like runs. ing.

However, as shown in FIG. 11, in the conventional lower frame structure of the translucent panel, the upper surface of the lower frame is flat. Therefore, as shown in FIG. 12, when the translucent panel is burned and the translucent plate is melted, the melted material is outside (the outside of the civil engineering structure such as a bridge and the translucent panel is separated from the road or railroad). There was a problem that there is a risk of personal injury and fire spread to buildings in civilian areas by spilling or falling to the side not facing the public side, generally the private side, the same hereafter).

For example, in Patent Document 1, a plate thickness of the translucent panel 2 in a sound insulation wall of a type in which a transversal panel 2 made of a synthetic resin is supported at its lateral ends and a vertical member is demarcated by a transversal member 3. Along the vicinity of the directional surface, a transparent panel 2 having a lattice-like end portion and made of a fireproof filament 5 supported by a vertical member 1 and a horizontal member in the vicinity of the translucent panel 2 is attached. An optical sound insulation wall is disclosed (refer to claim 1 of patent document 1, paragraphs [0011] to [0026] of the specification, FIG. 1 and FIG. 8 of the drawings, etc.).

However, the translucent sound-insulating wall described in Patent Document 1 has a fireproof wire so that the translucent panel 2 softened by the heat of the fire does not fall outside (the private side) when a fire occurs due to a vehicle accident or the like. The object (wire rope) 5 is to receive it. For this reason, it is not possible to reliably prevent the melted material of the translucent panel 2 made of synthetic resin from flowing out (to the private side) and causing personal injury to a person who passes by. It was

Further, in Patent Document 2, a panel provided with a face plate having a sound insulation property and at least a lower frame member that supports the face plate, wherein a rainwater receiver for receiving rainwater flowing down on the face plate surface on the upper surface of the lower frame member is disclosed. A soundproof panel in which a groove is formed is disclosed (refer to claim 2 of Patent Document 2, paragraphs [0016] to [0023] in the description, FIGS. 2 and 3 of the drawings, etc.).

However, the soundproof panel described in Patent Document 2 is intended to perform self-cleaning by providing a photocatalyst containing layer on the surface of the lower frame member, and the transparent plate (transparent panel) burns. It was not envisioned to catch the dissolved lysate. That is, no consideration has been given to preventing the accident that the melted material in which the transparent plate is melted and falls to the outside due to the burning of the transparent panel due to the aforementioned vehicle accident or the like. Further, in the narrow rainwater receiving groove 11 in which these matters are not taken into consideration, the problem that the melted material of the highly transparent viscous plate cannot be received and prevented from falling outside has not been solved.

Further, in Patent Document 3, rainwater collected by a gutter-shaped rain receiving portion 1 which is provided on an upper portion of a soundproof panel 10 and extends outward from an upper shield is provided on an inner surface and/or an outer surface. In the situation where there is a shield above the sound insulation wall and rainwater directly hitting it cannot be expected, the inner surface of the topmost soundproof panel 10a can be washed with the rainwater, and contaminants can be washed away and the transparency can be improved. There is disclosed a soundproof panel cleaning structure capable of holding the following (claim 1 of the patent document 3, paragraphs [0016] to [0023] of the specification, FIGS. 2 and 3 of the drawings, etc.). reference).

However, the soundproof panel cleaning structure described in Patent Document 3 is a cleaning structure for washing away contaminants and maintaining transparency, and is provided with an overhanging member (rain catching portion 1) protruding outward from the frame member. However, it is a projecting member that projects outward from the upper frame. Therefore, the overhanging member (rain receiving portion 1) of the soundproof panel described in Patent Document 3 cannot receive the melted material when the light transmissive panel (soundproof panel) is burned and the light transmissive plate is melted. Met.

[First Embodiment]
First, the lower frame structure of the translucent panel according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 7. FIG. 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 thereof. FIG. 4 is an enlarged end view of the translucent panel taken along the line AA of FIG. 1 with a part of the translucent panel omitted, and FIG. It is a BB line cutting part enlarged sectional view. Here, the front side refers to a state in which the front surface is viewed vertically and horizontally with respect to the plate surface of the translucent plate when viewed from the road or rail side (hereinafter referred to as the inside) that is the source of noise.

As shown in FIGS. 1 to 5, the translucent panel 1 according to the present embodiment mainly includes a translucent plate G1 and a panel frame 2 that is a frame body in which the translucent plate G1 is fitted. ing. This translucent panel 1 is attached to a column H (see FIG. 4) made of H-shaped steel or the like that is erected along a road or a railroad, and a sound insulation wall that prevents the propagation of noise generated from vehicles such as automobiles and trains. Used as. In the translucent panel 1, the translucent plate G1 has translucency, and the other side (outer side) of the wall is visible when viewed from the inside.

<Transparent plate>
The translucent plate G1 according to the present embodiment is made of resin glass such as polycarbonate, acrylic resin, and bioengineering plastic whose main raw material is isosorbide (isosorbide). However, instead of the resin glass, the present invention is also applied to the case where the resin film or the like is attached to the outside of the inorganic glass such as chemically strengthened laminated glass having a resin film interposed between the chemically strengthened glasses and general float glass. Can be applied. In short, the present invention can be applied to a translucent panel in which part or all of the translucent plate may melt and flow out to the outside when the translucent panel burns due to a vehicle accident or the like.

<Panel frame>
The panel frame 2 is an alumite frame body made of an extruded aluminum alloy, and as shown in FIGS. 1 to 5, a pair of left and right vertical frames 3 and 3 and upper ends of these vertical frames 3 and 3. And an upper frame 4 and a lower frame 5 spanning the lower end.

As shown in FIGS. 4 and 5, in the panel frame 2 according to the present embodiment, in order to support the translucent plate G1 made of resin glass, the vertical frame 3, the upper frame 4, and the lower frame 5 are provided with ridges 6. The four edges of the translucent plate G1 are fixed by being pressed and fixed from the inside by these push edges 6.

(Vertical frame)
As shown in FIG. 4, the vertical frame 3 is fixed to the column H.

The rim 6 is attached to the vertical frame 3, and the translucent plate G1 is fitted between the vertical frames 3 and 3. A gasket Ge made of a rubber elastic body such as silicon resin is attached to the rim 6 at a portion in contact with the light transmitting plate G1.

(Upper frame)
As shown in FIG. 5, the upper frame 4 is composed of an upper frame main body 40 which is a strip material whose vertical cross section is substantially rectangular and whose upper center is recessed along the longitudinal direction. A translucent plate mounting groove 41 for mounting the translucent plate G1 is formed therein. Reference numeral 42 is a gasket mounting groove 42 for elastically supporting the transparent plate so as not to be broken when inorganic glass having low impact resistance is mounted. As shown in FIG. 5, when the translucent plate G1 is made of resin glass, the gasket mounting groove 42 is mounted with a bolt for locking the upper side portion of the translucent plate G1. Needless to say, as shown in FIG. 11, the translucent plate G1 may be mounted on the setting block SB instead of being bolted.

(Bottom frame)
FIG. 6 is an enlarged end view of the C portion of FIG. 3 mainly showing the lower frame 5 of the translucent panel 1. As shown in FIGS. 5 and 6, like the upper frame 4, the lower frame 5 is composed of a lower frame main body 50 which is a strip material whose vertical cross section is substantially rectangular and whose lower center is recessed along the longitudinal direction. A transparent plate mounting groove 51 for mounting the transparent plate G1 is formed on the inner side of the upper surface of the lower frame body 50. Note that the gasket mounting groove 52 is formed in the lower frame 5 as in the upper frame 4.

Then, as shown in FIGS. 5 and 6, as a fitting mechanism for fitting an overhanging member 8 to be described later, the lower frame 5 is fitted along the longitudinal direction in which the upper corner is opened to the outer corner portion of the upper surface. A groove 56 is formed.

((Overhang member))
Next, with reference to FIGS. 5 and 6, the overhang member 8 which is a characteristic part of the present invention will be described.
As shown in FIGS. 5 and 6, at the outer edge of the lower frame main body 50, a melted product that is projected from the outer surface of the lower frame 5 to the outside in the horizontal direction and a part or all of the transparent plate G1 is melted A projecting member 8 is provided to prevent outflow to the outside of the frame.

As shown in FIG. 5, the projecting member 8 is a member that is molded separately from the lower frame 5 so that it can be retrofitted. The projecting member body 80 has a trapezoidal cross section, and the projecting member body 80. A plurality of ridges 81, 81' formed on the upper surface of the. In addition, the protruding member main body 80 is formed with a fitting claw 82 that fits into the above-described fitting groove 56 formed at the inner corner, a screw hole 83 formed in the protruding member main body 80, and the like. ing. Then, as shown in FIG. 6, an end face in the longitudinal direction of the overhang member main body 80 is closed by screwing the side surface panel 84 with a bolt B2 in a screw hole 83. For this reason, it is possible to prevent wind noise generated at the end face, and to hide the inside of the end face to improve the appearance. The overhang member 8 may be integrally formed with the lower frame 5. However, by making it possible to retrofit it separately from the lower frame 5, it is possible to prevent the protruding member 8 protruding outward from the panel frame 2 from interfering when the translucent panel 1 is stacked flat.

(Overhang member body)
The overhang member main body 80 has a flat surface with a substantially flat upper surface, and has a shape in which a flange 80a for bolting projects downward from the main body having a horizontally long trapezoidal cross section. Further, in the overhang member main body 80, the upper surface connected to the lower frame 5 on the inner side of the innermost ridge 81 is a melted material receiving portion 80b for storing the melted material.

The melted material receiving portion 80b has a flat surface and is flush with the upper surface of the lower frame body 50. That is, the overhanging member 8 is attached to the lower frame 5 so that the height of the flat surface of the melted material receiving portion 80b is the same as the height of the upper surface of the lower frame body 50. For this reason, precipitation such as rainwater is not blocked by the step and accumulated, and the drainage can be performed from the end portion of the overhang member main body 80. Further, since there is no step and the surface is flush, it is easily blown off by wind or the like, and sand and flying dust are less likely to collect on the overhanging member 8 and the lower frame 5.

The upper surface connected to the lower frame 5 of the overhanging member 8 may be mounted at a position lower than the upper surface of the lower frame main body 50 instead of being flush with each other. This is because even if there is a step in the downward direction, it is possible to drain water from the end of the overhang member body 80.

(Convex)
The ridges 81 are rib-shaped members with a relatively low height formed along the longitudinal direction protruding upward by about 2.5 mm from the upper surface of the overhanging member main body 80, and in this embodiment, four ribs are provided. The ridges 81 and 81' are formed. However, the outermost ridge 81' is a ridge with rounded corners so as to prevent injury at sharp edges. Further, as shown in FIG. 7C, as a modified example, the outermost ridge 81′ is a ridge 81″ having a height of about 10 mm, and the other upper surface is flat without ridges. It may be configured.

These ridges 81 and 81' slow down the flow (movement) speed of the melt of the resin having a viscosity higher than that of water so that the melt is cured by being cooled by the outside air so that the melt does not flow out of the frame. It has a function.

Further, even in the innermost ridge 81, the ridge 81 is provided outside the lower frame 5 by a predetermined distance, and the upper surface of the separated bulging member body 80 has the above-mentioned flat melt. It is a receiving portion 80b.

(Mating claw)
The fitting claw 82 is flush with the melt receiving portion 80b and protrudes inward from the overhanging member main body 80, and is bent downward, so that the fitting claw 82 is fitted into the fitting groove 56 whose upper side is opened. Combined to form a fitting structure that does not fall by gravity. For this reason, even if a connecting member such as a bolt or a rivet deteriorates over time, the protruding member 8 is extremely unlikely to fall off.

7A to 7C are process explanatory diagrams showing work steps of mounting work of the overhanging member 8 to the lower frame 5, where FIG. 7A shows a slide fitting step and FIG. 7B shows a bolt mounting step. When attaching the overhanging member 8 and the lower frame 5 on site, first, as shown in FIG. 7A, first, the flange 80a of the overhanging member 8 is brought into contact with the outer surface of the lower frame 5 and slid downward. The fitting claw 82 is fitted into the fitting groove 56 to be slid. Next, as shown in FIG. 7B, in a state where the fitting claw 82 is fitted in the fitting groove 56 and is temporarily placed, the protruding member 8 is slid to the left and right, and the lower frame main body 50 and the flange 80a. Align both bolt holes. Then, the bolt B1 is inserted into the nut N previously mounted in the lower frame body 50 and bolted to complete the work of attaching the overhanging member 8 to the lower frame 5.

In short, only by fitting the fitting claws 82 into the fitting grooves 56, the vertical alignment of the overhanging member 8 is completed, and temporary placement is also possible. Therefore, the positioning is easy, and one person can efficiently perform the work of mounting the overhang member 8 to the lower frame 5 in a short time.

According to the lower frame structure of the translucent panel 1 according to the first embodiment described above, since the overhanging member 8 is provided on the outer side of the lower frame 5, the resin material which is a fluid having a relatively high viscosity is used. The melted material can be temporarily stored in the overhanging member 8 and can be prevented from flowing out of the lower frame 5. Therefore, even when the translucent panel 1 is burned due to a vehicle accident or the like, it is possible to prevent an accident in which the melted material of the translucent plate G1 that may cause human damage or spread the fire is leaked to the outside.

Further, according to the frame structure of the translucent panel 1 according to the first embodiment, the overhanging member 8 is configured to be retrofittable separately from the lower frame 5, so that the overhanging member 8 is installed at the place where the translucent panel 1 is installed. Can be attached. Therefore, when the translucent panels 1 are stacked flat during transportation, the protruding member 8 protruding outward from the panel frame 2 does not interfere. In addition, it is economical to install the overhanging member while confirming the downward direction and the neighboring situation only in the places where countermeasures against dissolved matter are required, such as overpasses and areas near private areas.

Moreover, according to the frame structure of the translucent panel 1 according to the first embodiment, since the overhanging member 8 is fixed to the lower frame 5 by a mechanical fitting structure, the bolts and rivets deteriorate with age. However, the risk of the protruding member 8 falling off is extremely low. Further, since the positioning is easier than the positioning of the holes of the bolts and the bolts can be temporarily placed, it is possible for one person to efficiently and efficiently attach the overhanging member 8 to the lower frame 5.

In addition to that, according to the frame structure of the translucent panel 1 according to the first embodiment, since the plurality of ridges 81, 81′ are provided, the outflow of the melt of the resin material out of the frame is delayed, It is possible to reliably prevent the melt from flowing out by cooling the melt to lose its fluidity. Further, it is possible to prevent the snow accumulated by the ridges 81 from falling.

Further, according to the frame structure of the translucent panel 1 according to the first embodiment, since the melted material receiving portion 80b is a flat surface and is flush with the upper surface of the lower frame main body 50, precipitation is dammed by a step. It can be drained from the end of the overhang member body 80 without being stopped and accumulated. In addition, since there is no step and the surface is flush, sand and flying dust are easily blown off by the wind or the like, and are less likely to collect on the overhanging member 8 and the lower frame 5.

[Second Embodiment]
Next, the lower frame structure of the translucent panel according to the second embodiment of the present invention will be described with reference to FIG. The lower frame structure of the translucent panel according to the second embodiment of the present invention is different from the lower frame structure of the translucent panel according to the first embodiment described above mainly in the overhang member 8′ and the lower frame 5.

The lower frame 5 according to the second embodiment has substantially the same configuration as the lower frame 5 according to the first embodiment described above, but the fitting mechanism is not the fitting groove 56 described above but has an arc cross section. An arcuate groove 57 and a fitting groove 58 are formed in the middle of the outer surface of the lower frame body 50.

In addition, the outer edge of the lower frame main body 50 protrudes outward in the horizontal direction from the outer surface of the lower frame 5 to prevent the melted material from flowing out of the frame when part or all of the transparent plate G1 is melted. A bulging member 8'is provided.

The overhanging member 8′ includes an overhanging member main body 80′ having a trapezoidal cross-section with an open inner side surface, and a plurality of ridges 81, 81′ formed on the upper surface of the overhanging member main body 80′. Have Further, the overhang member main body 80 ′ is formed with an arcuate arcuate convex portion 82 ′ that fits into the above-mentioned arcuate concave groove 57, and a fitting claw 83 that fits into the above-described fitting groove 58. 'Is formed.

Further, in the overhang member main body 80 ′, the upper surface on the inner side of the innermost ridge 81 connected to the lower frame 5 serves as a melted substance receiving portion 80 ′b for storing a melted substance. The melted material receiving portion 80'b also has a flat surface and is flush with the upper surface of the lower frame body 50. Therefore, the precipitation is not blocked by the step and does not collect, and the water can be drained from the end portion of the overhang member main body 80'. In addition, since there is no step and the surface is flush, sand and flying dust are easily blown off by the wind or the like, and are less likely to collect in the overhanging member 8 ′ and the lower frame 5.

When attaching the overhanging member 8 ′ and the lower frame 5, first, the arcuate convex portion 82 ′ of the overhanging member 8 ′ is inserted into the arcuate concave groove 57 and guided by the arcuate concave groove 57 so that the overhanging member 8 ′ is removed. Rotate and rock. Then, the flange 80 ′ a comes into contact with the outer surface of the lower frame 5, and the fitting claw 83 ′ is hooked on the fitting groove 58. Then, the bolt holes of both the lower frame body 50 and the flange 80'a are aligned with each other, and the bolt B1 is inserted into the nut N previously mounted in the lower frame body 50 and bolted to complete the mounting work.

According to the frame structure of the translucent panel according to the second embodiment described above, the fitting structure of the overhanging member 8′ and the lower frame 5 is such that the fitting of the arc concave groove 57 and the arc convex portion 82′ and The fitting groove 58 and the fitting claw 83' are fitted together and two fitting structures are provided. Therefore, unless the above-mentioned overhanging member 8 ′ is rotated in the opposite swinging direction when it is fitted into the lower frame 5, the fitting between them does not come off. Therefore, even if the bolt B1 deteriorates over time, there is very little risk that the overhang member 8'will fall off.

Further, by merely inserting the arcuate convex portion 82' of the overhanging member 8'into the arcuate groove 57, the up-and-down alignment of the overhanging member 8'is completed and temporary placement is also possible. Therefore, the positioning is easy, and one person can efficiently perform the work of attaching the overhanging member 8 ′ to the lower frame 5 in a short time.

[Third Embodiment]
Next, the lower frame structure of the translucent panel according to the third embodiment of the present invention will be described with reference to FIG. The difference between the lower frame structure of the translucent panel according to the third embodiment of the present invention and the lower frame structure of the translucent panel according to the first embodiment is mainly that the convex stripes are formed on the upper surface of the overhang member 9. The point is that there is a step at 91. Therefore, that point will be mainly described, and the same configurations will be denoted by the same reference numerals and description thereof will be omitted.

FIG. 9 is a partially enlarged vertical end view showing the lower frame structure of the translucent panel according to the third embodiment of the present invention. The lower frame 5 according to the third embodiment has substantially the same configuration as the lower frame 5 according to the above-described first embodiment. Then, the outer edge of the lower frame body 50 protrudes outward in the horizontal direction from the outer surface of the lower frame 5 to prevent the melted material from flowing out of the frame when part or all of the transparent plate G1 is melted. A projecting member 9 is provided.

The bulging member 9 has a bulging member main body 90 having a trapezoidal cross section with an opening on the inner side surface, and a plurality of ridges 91, 91 ′ formed on the upper surface of the bulging member main body 90. There is. In addition, the protruding member main body 90 is formed with a fitting claw 92 that fits into the above-described fitting groove 56 formed at the inner corner. Further, the overhanging member main body 90 has a shape in which a flange 90a for bolting projects downward from a horizontally long trapezoidal main body.

The upper surface of the projecting member body 90 is a three-stepped surface having three flat surfaces 90b, 90c, and 90d with the ridge 91 as a boundary. Further, the overhanging member main body 90 has a shape in which a flange 90a for bolting projects downward from a horizontally long trapezoidal main body.

The flat surface 90b connected to the lower frame 5 serves as a melt receiving portion, and has a height one step lower than the upper surface of the lower frame main body 50. Therefore, the precipitation is not blocked by the step and does not collect, and the precipitation can flow to the flat surface 90b and be drained from the end portion of the overhang member main body 90 in the longitudinal direction.

The flat surface 90c is one step higher than the flat surface 90b and has the same height as the upper surface of the lower frame body 50, and the flat surface 90d is one step higher than the flat surface 90c. For this reason, not only the flat surface 90b but also the flat surface 90c and the flat surface 90d can function as a melt receiving portion.

[Fourth Embodiment]
Next, the lower frame structure of the translucent panel according to the fourth exemplary embodiment of the present invention will be described with reference to FIG. 10. The lower frame structure of the translucent panel according to the fourth exemplary embodiment of the present invention is different from the lower frame structure of the translucent panel according to the first exemplary embodiment mainly in that of the overhang member 10 and the lower frame 5. They are the fitting structure and the shape of the ridge 101. Therefore, that point will be mainly described, and the same configurations will be denoted by the same reference numerals and description thereof will be omitted.

FIG. 10 is a vertical partial end view showing the lower frame structure of the translucent panel according to the fourth embodiment. The lower frame 5 according to the fourth embodiment has substantially the same configuration as the lower frame 5 according to the above-described first embodiment, but as a fitting mechanism, not the above-described fitting groove 56 but a fitting recess 59. Are formed.

In addition, the outer edge of the lower frame main body 50 protrudes outward in the horizontal direction from the outer surface of the lower frame 5 to prevent the melted material from flowing out of the frame when part or all of the transparent plate G1 is melted. A projecting member 10 is provided.

The bulging member 10 has a bulging member main body 100 having a trapezoidal inner cross section, and a plurality of ridges 101, 101 ′ having a triangular cross section formed on the upper surface of the bulging member main body 100. There is. In addition, the protruding member main body 100 is formed with a fitting convex portion 102 that fits with the above-mentioned fitting concave portion 59, and the protruding member main body 100 is downwardly moved from a main body having a horizontally long trapezoidal cross section. The flange 100a for bolting has a protruding shape.

Further, in the overhang member main body 100, the upper surface on the inner side of the innermost ridge 101 connected to the lower frame 5 is a melted material receiving portion 100b for storing the melted material. The melted substance receiving portion 100b also has a flat surface and is flush with the upper surface of the lower frame main body 50. However, the distance between the inner ridge 81 and the lower frame 5 of the innermost ridge 101 is shorter than the inner ridge 81. That is, the melted material receiving portion 100b has a smaller area than the melted material receiving portion 80b.

However, since the innermost ridge 101 is also spaced apart from the lower frame 5, the precipitation is not blocked by the step and does not collect, and the drainage can be drained from the end of the overhang member main body 100. .. Moreover, since there is no step and the surface is flush, sand and flying dust are easily blown off by the wind or the like, and are less likely to collect on the overhanging member 100 and the lower frame 5.

When attaching the projecting member 10 to the lower frame 5, first, the fitting convex portion 102 of the projecting member 10 is pressed against the fitting concave portion 59. Then, the fitting convex portion 102 is inserted into the fitting concave portion 59 while being guided by the tapered surface of the fitting convex portion 102. This completes the vertical positioning of the overhang member 10. After that, the bolt holes of both the lower frame main body 50 and the flange 100a are aligned, the bolt B1 is inserted into the nut N previously mounted in the lower frame main body 50 and bolted, and the mounting work is completed.

Therefore, according to the frame structure of the translucent panel according to the fourth embodiment described above, in addition to the above-described operational effects, although temporary placement is not possible, positioning is extremely easy, and the lower frame 5 of the overhanging member 10 can be positioned. Can be installed in a short time.

Although the lower frame structure of the translucent panel according to the first to fourth embodiments of the present invention has been described above in detail, the above-described or illustrated embodiments are all embodied in carrying out the present invention. It is just a morphology. Therefore, the technical scope of the present invention should not be limitedly interpreted by these.
