Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand, the present invention will be further described with reference to the following specific drawings and embodiments.

The utility model provides a road sound insulating barrier 10 that sets up along the highway limit, including acoustic celotex board 20 and metal frame 31 frame 30, acoustic celotex board 20 is arranged along the roadside, promptly, and acoustic celotex board 20 has the roadside and the part of the people's place side opposite with the roadside. A substantially plate-shaped road side plate 21 is disposed on the road side. A substantially plate-shaped civil-land side plate 22 is disposed on the residential-land side, and the civil-land side plate 22 and the road side plate 21 are disposed with a gap therebetween.

A substantially plate-shaped partition glass plate 23 is interposed between the highway side plate 21 and the civil field side plate 22 for partitioning the highway side plate 21 and the civil field side plate 22, i.e., the partition glass plate 23 is sandwiched between the highway side plate 21 and the civil field side plate 22.

As shown in fig. 1, the highway side plate 21 and the partition glass plate 23 are bonded together with a first intermediate film 24 interposed therebetween, the civil-ground side plate 22 and the partition glass plate 23 are bonded together with a second intermediate film 25 interposed therebetween, and the soundproof plate 20 includes the highway side plate 21, the first intermediate film 24, the partition glass plate 23, the second intermediate film 25, and the civil-ground side plate 22 in this order from inside to outside.

The example in fig. 1 is an example in which one spacer glass plate 23 is sandwiched between the highway side plate 21 and the civil field side plate 22, but the number of the spacer glass plates 23 is not particularly limited.

The road side plate 21 and the civil field side plate 22 are made of chemically strengthened glass. Chemically strengthened glass is a glass in which sodium ions having a small ionic radius on the surface of molten potassium salt (potassium nitrate, potassium sulfate, potassium hydrogen sulfate, potassium carbonate, potassium hydrogen carbonate, potassium chloride, etc.) are replaced with potassium ions having a large ionic radius, thereby forming a compressive stress layer on the surface of the glass.

The chemically strengthened glass is excellent in heat resistance and impact resistance as compared with float glass, and is less likely to spontaneously break without applying an external force as compared with ordinary air-cooled tempered glass. Further, the impact strength (surface strength) at the center of the chemically strengthened glass is lower than that of other glasses (float glass, wired glass, thermally strengthened glass, air-cooled tempered glass, and the like).

On the other hand, the spacer glass plate 23 is made of glass, preferably float glass, which is a common soda-lime-silicate glass (or borosilicate glass, etc.), or a wired glass. The wired glass is glass with metal wires inside, and the metal wires can prevent the glass from flying apart when the glass is broken.

The utility model discloses the purpose of acoustic celotex board 20 is that the conflagration that prevents traffic accident on the road and shock wave influence residential area, consequently, keeps the complete shape of civilian ground curb plate 22 as far as possible, or even the civilian ground curb plate 22 breaks, glass pieces is also very little, or even glass is smashed, the piece also can be supported to wired or net, hardly collapses and the breakage, can not cause serious safety influence.

As described above, the soundproof panel 20 has the spacer glass plate 23 between the highway side panel 21 and the civil side panel 22. Since the spacer glass plate 23 is interposed, the occurrence of burn-through in the civil side panel 22 can be suppressed. That is, the fire resistance of the baffle plate 20 can be improved by providing the spacer glass plate 23. If float glass or wired glass is used as the spacer glass plate 23, the glass tends to be thick and have a large heat capacity. Even if a fire breaks out on the roadside, it takes a considerable time for the heat to spread to the residential areas.

The thickness of the spacer glass plate 23 is preferably 3mm to 19mm, and it is preferable that the influence of heat generated by heating does not easily reach the residential side plate 22 on the residential side when the thickness of the spacer glass plate 23 is in the range of 3mm to 10mm as confirmed by experiments.

The spacer glass plate 23 can be manufactured at low cost by using float glass or wired glass as a glass plate, and is widely used.

Further, since the partition glass plate 23 is interposed between the road side plate 21 and the civil air side plate 22, the rigidity of the entire soundproof plate 20 and the soundproof barrier 10 is increased, and therefore, the impact resistance from the road side can be improved.

Further, since the highway side panel 21 and the civil field side panel 22 are made of chemically strengthened glass, the impact resistance is improved. In particular, by disposing the chemically strengthened glass having high impact resistance on the road side plate 21, impact from the road side can be received, and the impact resistance of the entire road sound-insulating barrier 10 can be improved. The thickness of the highway side plate 21 is 2.0mm-8.0mm, and the thickness of the civil field side plate 22 is 1.5mm-5.0mm. The thickness of the side plate 21 is thicker than that of the side plate 22 because the application of the present invention is applied to the road, and the side plate must first receive the impact from the side of the road. From this viewpoint, the thickness of the highway side panel 21 is preferably thicker than that of the civil side panel 22.

In addition, the thickness of the civil side plate 22 is set to 1.5mm to 5.0mm, so that the fragments can be prevented from being increased when the civil side plate 22 is damaged. In other words, the impact of debris on the safety of a populated area can be minimized. In addition, by using chemically strengthened glass, natural breakage of air-cooled tempered glass does not occur.

The structure of the partition board 20 of the present invention is shown in fig. 7 as allowable stress at the edge portion and allowable stress at the central portion of different glasses, with attention paid to the characteristics of each glass. Since the road acoustic panel 20 is substantially composed of glass, it has excellent light transmittance and does not hinder visibility. Due to the application to the road, an excellent view can be provided for the driver. Further, it has more excellent durability, higher transparency, and more beautiful appearance than when a resin such as polycarbonate is used as the soundproof plate 20.

For the first interlayer film 24 and the second interlayer film 25, polyvinyl butyral, ionomer resin, or the like is used. In general, thermoplastic resins, thermosetting resins, UV-curable resins, and the like, as well as vinyl polymers, ethylene-vinyl monomer copolymers, styrene copolymers, urethane resins, fluorine resins, and acrylic resins can be used.

When the soundproof panel 20 is mounted on the frame 30 on both sides or one side of the road, it is first assembled into the metal frame 31. Specifically, as shown in fig. 2 and 3, the entire periphery of the baffle plate 20 is fitted so as to be covered with the metal frame 31. Fig. 2 shows a cross-sectional view from the side, and fig. 3 shows a cross-sectional view from above. The metal frame 31 has a substantially rectangular frame 30 shape, and includes an upper horizontal frame 311, a lower horizontal frame 312, two side vertical frames 313, and a stopper frame 314. The upper horizontal frame 311, the lower horizontal frame 312 and the vertical frame 313 at one side of the civil area side panel 22 are partially extended inward to cover the periphery of the civil area side panel 22, that is, the inner peripheral edge of the metal frame 31 at one side of the residential area is partially extended inward to limit the portion of the civil area side panel 22 of the soundproof panel 20, then the blocking frame 314 is installed at one side of the highway, the periphery of the blocking frame 314 is pressed against the portion of the highway side panel 21 of the soundproof panel 20, and the periphery of the blocking frame 314 is fixed with the upper horizontal frame 311, the lower horizontal frame 312 and the vertical frames 313 at two sides by self-tapping screws 315.

As shown in fig. 2 and 3, it is preferable that gaskets 316 are provided around both front and rear sides of the sound insulation panel 20, that is, gaskets 316 are provided around the exterior of the highway side panel 21 and around the exterior of the civil side panel 22, wherein one ring of the gaskets 316 is located between the sound insulation panel 20 and the blocking frame 314, and the other ring of the gaskets 316 is located between the sound insulation panel 20 and the upper horizontal frame 311, the lower horizontal frame 312, and the vertical frames 313. The gasket 316 serves to prevent water from entering the metal frame 31.

As shown in fig. 4, it is preferable that a catching groove 3111 is formed along a longitudinal direction of the upper horizontal frame 311, a catching plate 3121 into which the catching groove 3111 is inserted is formed along a longitudinal direction of the lower horizontal frame 312, and the metal frame 31 are coupled to each other by catching between the catching groove 3111 and the catching plate 3121.

As shown in fig. 5 and 6, the H-shaped steel 32 is disposed on one side of the road at intervals, a plurality of metal frames 31 are installed in the height direction between every two H-shaped steels 32, and the sound insulation board 20 of the present invention is installed in each metal frame 31, so as to form the whole sound insulation barrier 10, and the vertical frames 313 on both sides of the metal frames 31 and the two sides of the baffle frame 314 are inserted into the grooves 321 of the H-shaped steels 32 correspondingly.

The soundproof panel 20 was subjected to a fire resistance test, and as shown in fig. 8, 4 soundproof panels 20 of comparative examples and 7 soundproof panels 20 of examples were used for the test, and all of the soundproof panels 20 of comparative examples were made of only two glass panels, namely, a highway side panel 21 and a civil-land side panel 22, and in the comparative examples and examples, the highway side panel 21 and the civil-land side panel 22 were made of chemically strengthened glass, specifically, comparative example 1 was laminated glass having a thickness of 3mm each, comparative example 2 was laminated glass having a thickness of 4mm each, comparative example 3 was laminated glass having a thickness of 5mm each, and comparative example 4 was laminated glass having a thickness of 6mm each.

Except for example 7, all the spacer glass plates 23 of the other examples were made of float glass. In example 7, wired glass was used as the spacer glass plate 23. Specifically, in example 1, the highway side plate 21 was a 4mm chemically strengthened glass plate, the spacer glass plate 23 was a 4mm float glass plate, and the civil side plate 22 was a 4mm chemically strengthened glass plate;

in example 2, the highway side plate 21 was a 5mm chemically strengthened glass plate, the spacer glass plate 23 was a 3mm float glass plate, and the civil side plate 22 was a 5mm chemically strengthened glass plate;

in example 3, the highway side plate 21 was a 4mm chemically strengthened glass plate, the spacer glass plate 23 was a 5mm float glass plate, and the civil side plate 22 was a 4mm chemically strengthened glass plate;

in example 4, the highway side plate 21 was a 4mm chemically strengthened glass plate, the spacer glass plate 23 was a 6mm float glass plate, and the civil side plate 22 was a 4mm chemically strengthened glass plate;

in example 5, the highway side plate 21 was a 4mm chemically strengthened glass plate, the spacer glass plate 23 was an 8mm float glass plate, and the civil side plate 22 was a 4mm chemically strengthened glass plate;

in example 6, the highway side plate 21 was a 4mm chemically strengthened glass plate, the spacer glass plate 23 was a 10mm float glass plate, and the civil side plate 22 was a 4mm chemically strengthened glass plate;

in example 7, the highway side plate 21 was a 4mm chemically strengthened glass plate, the spacer glass plate 23 was a 6.8mm wired glass plate, and the civil side plate 22 was a 4mm chemically strengthened glass plate.

In the fire resistance test, the side of the highway side panel 21 of each sound insulating panel 20 is exposed to flame, heated for a predetermined time, and checked for the presence of burn-through (the civil side panel 22 falls down on the side of the land in the residential area). The soundproof panel 20 used for the test had a height of 1m and a width of 2m, and four sides of the soundproof panel 20 were aluminum frame metal frames 31. Four fire tests were carried out, respectively, with fire test 1 being 4 minutes, fire test 2 being 5 minutes, fire test 3 being 8 minutes and fire test 4 being 10 minutes.

As is clear from the experimental results shown in FIG. 9, comparative examples 1 to 4 were burnt out in the fire resistance test 1. Specifically, after heating for 1 to 2 minutes, the highway side panel 21 was cracked, after 3 minutes, the highway side panel 21 was peeled off, and after 3 to 4 minutes, the civil area side panel 22 on the residential area side was cracked, and the fire was released from the cracks.

Since burnthrough occurred in each of comparative examples 1 to 4, the chemically strengthened glass of comparative examples 1 to 4 gradually became thicker, but the fire resistance did not change. Symbol ×: indicating that the entire baffle plate 20 is burned through and falls off;

on the other hand, in any of the acoustical panels 20 of examples 1 to 7, no burn-through occurred in the acoustical panel 20 in the fire resistance test 1. Thus, the fire resistance of the spacer glass plate 23 made of float glass or wired glass is also improved by being sandwiched in the chemically strengthened glass. Referring particularly to examples 1 and 2, although the total thickness is not much different from that of comparative examples 3 and 4, the soundproof panel 20 made of the spacer glass sheet 23 made of float glass or wired glass is more fire-resistant than the soundproof panel 20 made of the chemically strengthened glass simply by increasing the total thickness.

In addition, it is also cost effective to reduce the amount of chemically strengthened glass by including float glass as part of examples 1 and 2, rather than chemically strengthening the glass. Since chemically strengthened glass is very expensive, the amount of chemically strengthened glass used is as small as possible, but the fire resistance is improved, and the cost can be saved.

Furthermore, fire resistance test 2 was performed for examples 1 to 7. However, there were some differences in the results between examples 1-2 and examples 3-7. In examples 1 and 2, the highway side plate 21 and the partition glass plate 23 were detached, but the civil side plate 22 was not detached. The road side panels of examples 1, 2 cracked after heating for 1-2 minutes, and fell off after 3 minutes, and the spacer glass plate 234 broke immediately after heating and fell off within 4 to 5 minutes. After 5 minutes from the stop of heating, the civil side panel 22 was broken and dropped off.

On the other hand, in examples 3 to 7, the civil side panel 22 was not detached even after the heating was stopped in the fire resistance test 2, and only the road side panel was detached.

In fig. 9, a case where only one civil side plate 22 remains and comes off after the heating is stopped is indicated by a single circle "∘";

the remaining spacer glass plate 23 and the civil floor side plate 22 were not peeled off and indicated by "very good" with double circles.

In view of the above, by setting the thickness of the spacer glass plate 23 to 1.25 times or more the thickness of the civil side plate 22, it is possible to obtain an improvement in the fire resistance as compared with example 1 in which the thickness is 1 time.

Then, fire resistance test 3 was conducted, and as a result, the partition board 20 was burned through in examples 1 to 3. In example 4 (the thickness of the spacer glass plate 23 is 1.5 times the thickness of the civil side plate 22), only the civil side plate 22 remains, and the civil side plate 22 also falls off after the heating is stopped. In examples 5 to 7, neither the spacer glass plate 23 nor the civil side plate 22 was detached.

In the fire resistance test 4, burn-through occurred in example 4, and in example 5 (the thickness of the spacer glass plate 23 was 2 times the thickness of the civil side panel 22), the civil side panel 22 was detached after the heating was stopped. In example 6 (the thickness of the spacer glass plate 23 is 2.5 times the thickness of the civil side plate 22) and example 7, neither the spacer glass plate 23 nor the civil side plate 22 fell.

In examples 3 to 6, the thickness of the spacer glass plate 23 was 1.25 times or more the thickness of the civil side panel 22, the spacer glass plate 23 was float glass, and the thickness of the spacer glass plate 23 was gradually increased in the order of examples 3 to 6.

Referring to the results of fire resistance tests 3 and 4, it can be understood that the thicker the thickness of the spacer glass plate 23, the higher the fire resistance. According to examples 1 to 6, it can be understood that when the thickness of the spacer glass plate 23 is 1.25 times or more the thickness of the civil side plate 22, the fire resistance is improved accordingly. Therefore, it can be known that the thickness of 1.25 times or more is a key index.

Specifically, the fire tests of examples 3-6 show that the highway siding 21 cracks after 1-2 minutes and falls off after 3 minutes. Since the spacer glass plate 23 is float glass, it is cracked with heating for a short time. In examples 3 to 6, the thickness of the spacer glass plate 23 was increased, and as the thickness was increased, the intermediate film between the spacer glass plate 23 and the civil side plate 22 was less likely to melt and maintain the adhesive strength, and the spacer glass plate 23 was less likely to fall off. In the example using float glass as the spacer glass plate 23, example 6 was subjected to the fire resistance test 4 with the longest heating time, and if it was 2.5 times or more, the safety could be more secured.

In example 7, no burn-through occurred in any of the fire tests 1 to 4, and in the fire test of example 7, the highway side panel 21 cracked after 1 to 2 minutes and fell off after 3 minutes. The spacer glass plate 23 cracks immediately after heating, but the spacer glass plate 23 and the civil side plate 22 never fall off. Even if the heating time of the fire test 4, which is the longest heating time, passes, the civil side panel 22 does not fall down.

As described above, it was found that the use of wired glass as the spacer glass plate 23 can make the thickness thinner than that of float glass and exhibit equal or higher fire resistance (total thickness of 14mm in example 4, 16mm in example 5, 18mm in example 6, and 12.8mm in example 7).

As described above, it was confirmed that the time until the burn-through occurred can be extended by sandwiching the spacer glass plate 23 in the chemically strengthened glass. In comparative example 4 and example 1, the total thickness of the soundproof plate 20 was the same and 12mm, but example 1 was more flame-resistant.

In comparative examples 2 to 4 and example 1, the thickness of the chemically strengthened glass of the partition plate 20 in example 1 was equal to or thinner than the thickness of the chemically strengthened glass, but it was found that example 1 required a long time until the occurrence of the burnthrough.

Comparing example 1 with examples 3 to 6, it was confirmed that the time taken for the entire baffle plate 20 to burn through increases as the thickness of the spacer glass plate 23 increases, although the thickness of the chemically strengthened glass used is the same.
