Description

Technical Field

[0001] This utility model relates to the technical field of sound barrier facilities, and in particular to a fireproof and fully enclosed sound barrier. Background Technology

[0002] Currently, with the rapid development of society and economy, light rail, railways and highways have installed fully enclosed sound barriers in sections with high noise sensitivity during the construction period.

[0003] To balance light transmission, fully enclosed sound barriers often use translucent sound-insulating materials such as PC panels or acrylic panels. While PC panels and acrylic panels offer excellent light transmission and sound insulation, their plastic nature means they only achieve a Class B fire resistance rating. In the event of a fire within a fully enclosed sound barrier, which resembles a tunnel, this material can cause continuous combustion, resulting in extremely high losses.

[0004] Therefore, there is an urgent need to design a new type of sound barrier to reduce the losses caused by the continuous and violent burning of fully enclosed sound barriers due to vehicle fires. Utility Model Content

[0005] The purpose of this invention is to provide a fireproof, fully enclosed sound barrier. After studying numerous similar accident cases at home and abroad and researching sound insulation and sound-absorbing barrier materials on the market, and referring to the idea of ​​setting up firebreaks in forest fires, this invention adopts the concept of intermittently arranging high-fire-resistant noise-reducing materials. A metal barrier of appropriate width is set at certain intervals in the longitudinal direction of the fully enclosed sound barrier, which improves the overall fire resistance of the fully enclosed sound barrier, reduces the losses caused by fire hazards, and effectively solves the problem mentioned in the background art that existing fully enclosed sound barriers, which use continuous arrangement of light-transmitting sound insulation materials such as PC boards or acrylic boards, are prone to continuous combustion due to vehicle fires.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fire-resistant, fully enclosed sound barrier includes an arched support installed above a road. The arched support is fitted with several standard sound barrier units spanning the road longitudinally, and a fire-resistant isolation strip is provided at intervals of several spans, extending laterally along the road. The fire-resistant isolation strip is composed of at least one all-metal sound barrier unit. Each standard sound barrier unit spanning a road includes several translucent sound-insulating screens spliced ​​together at the top along the road transverse direction and several metal sound-absorbing screens spliced ​​together at the sides along the vertical direction. The all-metal sound barrier unit includes several metal sound-absorbing screens spliced ​​together at the top along the road transverse direction and several metal sound-absorbing screens spliced ​​together at the sides along the vertical direction.

[0008] Furthermore, a 4-meter-wide firebreak is installed every 100 meters along the longitudinal direction of the road.

[0009] Furthermore, the metal sound-absorbing screen is in the shape of a cuboid and includes a perforated metal panel, a metal back plate, metal side plates, and several metal keels located between the perforated metal panel and the metal back plate. Polyurethane sound-absorbing material is disposed between the perforated metal panel and the metal back plate.

[0010] Furthermore, the perforated metal panel has a perforation rate of 20% to 25% and a hole diameter of 2.5 mm to 3 mm.

[0011] Furthermore, the light-transmitting and sound-insulating screen body is rectangular in shape, and includes a rectangular light-transmitting plate and a metal frame surrounding the edge of the light-transmitting plate. The inner side of the metal frame is provided with an mounting groove for mounting the light-transmitting plate, and the mounting groove is provided with a U-shaped rubber strip located between the light-transmitting plate and the metal frame.

[0012] Furthermore, the standard sound barrier unit has symmetrical light-transmitting and sound-insulating screens on both sides.

[0013] Furthermore, steel wire rope anti-detachment components are connected between two adjacent spliced ​​metal sound-absorbing screens, between two light-transmitting sound-insulating screens, and between the metal sound-absorbing screen and the light-transmitting sound-insulating screen.

[0014] Furthermore, the arched support includes several portal-shaped support frames spaced longitudinally along the road and several purlins connected between two adjacent portal-shaped support frames. The portal-shaped support frames are provided with movable baffles for cooperating with the portal-shaped support frames to clamp the light-transmitting sound-insulating screen or the metal sound-absorbing screen. The movable baffles are provided with limit plates.

[0015] Furthermore, sealing strips are provided on both sides of the light-transmitting sound-insulating screen and on both sides of the metal sound-absorbing screen.

[0016] Furthermore, the standard sound barrier unit also includes ventilation louvers located above the centerline of the road.

[0017] Compared with the prior art, this utility model provides a fireproof and fully enclosed sound barrier, which has the following beneficial effects:

[0018] This invention utilizes all-metal sound barrier units arranged in a continuous ring from the top to the sides in the horizontal direction, forming a fire-resistant isolation zone that effectively blocks the spread of fire along the longitudinal direction of the road. Compared with the traditional concept of continuously arranging the same screen material in fully enclosed sound barriers, this intermittent fire-resistant isolation zone using high-fire-resistant materials balances noise reduction and lighting effects. At the same time, it greatly limits the fire range and extends rescue time without significantly increasing construction costs, thereby reducing the losses caused by fire. This invention provides a new fire prevention solution for industries such as light rail, railway, and highways. Attached Figure Description

[0030] The technical solution of this utility model will be clearly and completely described below through detailed embodiments and in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0031] Please refer to Figures 1-9 This embodiment provides a fireproof and fully enclosed sound barrier, including an arched support 2 installed above a road 1. The arched support 2 is equipped with several standard sound barrier units 3 distributed longitudinally along the road 1, and a fireproof isolation strip 4 is provided transversely along the road 1 at intervals of several spans. The fireproof isolation strip 4 is composed of at least one span of all-metal sound barrier unit 41. Each standard sound barrier unit 3 includes several light-transmitting sound-insulating screens 5 spliced ​​at the top along the transverse direction of the road 1 and several metal sound-absorbing screens 6 spliced ​​at the sides along the vertical direction. The all-metal sound barrier unit 41 includes several metal sound-absorbing screens 6 spliced ​​at the top along the transverse direction of the road 1 and several metal sound-absorbing screens 6 spliced ​​at the sides along the vertical direction. Because the all-metal sound barrier units are arranged in a continuous ring from the top to the side in the horizontal direction, forming a fire-resistant isolation zone, they can effectively block the spread of fire along the longitudinal direction of the road. Compared with the traditional concept of continuously arranging the same screen material in a fully enclosed sound barrier, this intermittent fire-resistant isolation zone using high-fire-resistant materials takes into account noise reduction and lighting effects. At the same time, it greatly limits the fire range and extends the rescue time without increasing the cost, thereby reducing the losses caused by the fire. It can provide a new fire prevention solution for industries such as light rail, railway, and highway.

[0032] In some implementation methods, as preferred, such as Figure 1 and Figure 2As shown, a 4-meter-wide firebreak 4 is set up every 100 meters along the longitudinal direction of road 1. This effectively prevents the spread of fire.

[0033] Specifically, as an example, the width of both the standard sound barrier unit 3 and the all-metal sound barrier unit 41 is 2m, which is the width of a standard span. That is, two all-metal sound barrier units are set for every 48 standard sound barrier units. This arrangement spacing is suitable for highways with a design speed of 100km / h. It mainly takes into account noise reduction, lighting, and fire prevention functions, and tries to avoid the grating effect caused by too small a spacing, which may dazzle the driver's eyes and cause road accidents.

[0034] In some specific implementation methods, refer to Figures 1-5 The arched support 2 includes several portal-shaped support frames 22 distributed longitudinally along the road 1 and several purlins 21 connected between two adjacent portal-shaped support frames 22. The portal-shaped support frame 22 is provided with a movable baffle 8 for cooperating with the portal-shaped support frame to clamp the light-transmitting sound insulation screen 5 or the metal sound-absorbing screen 6. The movable baffle 8 is provided with a limiting plate 81 for limiting the installation of the light-transmitting sound insulation screen 5 or the metal sound-absorbing screen 6.

[0035] Specifically, as an example, such as Figures 3-5 As shown, the portal frame 22 includes a steel crossbeam 222 at the top and steel columns 221 on both sides and in the middle of the road. The steel columns 221 and the steel crossbeam 222 are made of H-shaped steel, and the purlins 21 are made of C-shaped steel. The movable baffle 8 is made of angle steel with a specification of 85*50*5mm, and it is connected to the steel crossbeam 222 by M12 cotter pin bolts.

[0036] In some specific implementation methods, refer to Figure 8 and Figure 9 The metal sound-absorbing barrier 6 is rectangular in shape and includes a perforated metal panel 61, a metal back plate 62, metal side plates 63, and several metal ribs 64 located between the perforated metal panel 61 and the metal back plate 62. Polyurethane sound-absorbing material 65 is disposed between the perforated metal panel 61 and the metal back plate 62. The perforation rate of the perforated metal panel 61 is 20%–25%, and the pore diameter is 2.5mm–3mm. This configuration of the metal sound-absorbing barrier results in excellent sound absorption and achieves a fire resistance rating of Class A.

[0037] Specifically, as an example, the perforated metal panel 61 is made of aluminum alloy plate with a thickness of 1.5mm, a perforation rate of 25%, and a hole diameter of 3mm; the metal back panel 62 is made of galvanized steel plate with a thickness of 1.5mm; the polyurethane sound-absorbing material 65 is made of polyurethane sound-absorbing cotton with a thickness of 50mm; the metal keel 64 is made of galvanized keel channel steel with a thickness of 2mm; and the metal side panel 63 is made of galvanized steel plate with a thickness of 1mm.

[0038] In some specific implementation methods, refer to Figure 6 and Figure 7 The light-transmitting and sound-insulating barrier 5 is rectangular in shape. It includes a rectangular light-transmitting panel 51 and a metal frame 52 surrounding the edge of the light-transmitting panel 51. The inner side of the metal frame 52 has a mounting groove 521 for embedding the light-transmitting panel 51. A U-shaped rubber strip 53 is provided in the mounting groove 521 between the light-transmitting panel 51 and the metal frame 52. This design of the light-transmitting and sound-insulating barrier achieves excellent sound insulation and light transmission while also providing good sealing and installation performance.

[0039] Specifically, as an example, the light-transmitting panel 51 is a transparent acrylic panel (PC panel can also be used as needed), with two thicknesses: 12mm and 15mm. The thickness of the light-transmitting panel arranged at the top of the fully enclosed sound barrier is 12mm, and the thickness of the light-transmitting panel arranged on the side of the fully enclosed sound barrier is 15mm. The metal frame 52 is an aluminum alloy profile frame with a wall thickness of 1.5mm. It is electrostatically sprayed with fluorocarbon powder after chromic acid passivation or similar pretreatment. The surface should be smooth, uniform, and free of obvious manufacturing defects. The coating thickness of the electrostatically sprayed fluorocarbon powder on the outer surface of the profile is ≥40μm.

[0040] In some specific implementation methods, refer to Figure 4 and Figure 5 Along the longitudinal direction of the road, steel wire rope anti-detachment components 7 are connected between two adjacent spliced ​​metal sound-absorbing screens, between two light-transmitting sound-insulating screens, and between metal sound-absorbing screens and light-transmitting sound-insulating screens, so as to prevent them from falling off.

[0041] Specifically, as an example, the sidewalls of the metal sound-absorbing screen 6 and the light-transmitting sound-insulating screen 5 are provided with U-shaped buckles 72, and the wire rope anti-detachment assembly 7 includes a wire rope 71 for connecting to the U-shaped buckles 72.

[0042] In some specific implementation methods, refer to Figure 4 and Figure 5 Sealing strips 9 are provided on both sides of the light-transmitting soundproof barrier 5 and both sides of the metal sound-absorbing barrier 6 to improve the sealing performance of the installation. Specifically, as an example, the sealing strips 9 are made of EPDM rubber.

[0043] In some improved implementations, refer to Figure 2 and Figure 3 The standard sound barrier unit 3 is also symmetrically provided with light-transmitting and sound-insulating screens 5 on both sides, which can increase the lighting effect.

[0044] In some improved implementations, refer to Figure 1 and Figure 3The standard sound barrier unit 3 further includes ventilation louvers 10 located above the centerline of the road 1, thereby achieving the effect of ventilation, heat exchange and air exchange.

Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
