Description

TECHNICAL FIELD

[0001] The present application relates to the field of road noise reduction facilities, in particular to a sound barrier prefabricated baffle and a mounting method thereof. BACKGROUND

[0002] A sound barrier is a facility inserted between a sound source and a receiver to make the sound wave propagation have a significant additional attenuation, thereby weakening the noise impact in a certain area where the receiver is located, and such a facility is called a sound barrier.

[0003] The semi-closed sound barrier prefabricated baffle used on the road is usually composed of a sound insulation board and a mounting base, and the bottom of the sound insulation board is integrally provided with the mounting base. The mounting base is usually fixed on the side of the road by expansion bolts, so as to ensure that it can be effectively fixed on the side of the road or bridge.

[0004] However, in some special cases, such as a traffic accident hitting the sound insulation board, or encountering extreme weather with high wind level, the sound insulation board may be broken. If the road is set on the bridge, the broken sound insulation board is easy to fall to the bridge below, which brings great danger to the surrounding public facilities and pedestrians. SUMMARY

[0005] In order to reduce the dangerous situation caused by the broken sound insulation board, the present application provides a sound barrier prefabricated baffle and a mounting method thereof.

[0006] In a first aspect, the present application provides a sound barrier prefabricated baffle adopting the following technical scheme:

[0007] A sound barrier prefabricated baffle is installed on one side of a road, comprising an integrally formed sound insulation board and a mounting base, the mounting base is connected with a locking mechanism for fastening connection between the mounting base and the road, the road is installed with a limiting mechanism, the limiting mechanism comprises a limiting plate installed on the side of the sound insulation board away from the road, the height of the limiting plate is not lower than that of the sound insulation board, and sound insulation cotton is filled between the sound insulation board and the limiting plate.

[0008] By adopting the above technical scheme, the prefabricated baffle is transported to the road, and then the mounting base is fastened and connected with the road by the locking mechanism, and the limiting plate is located on the side of the sound insulation board away from the road. When the sound insulation board is broken due to special circumstances, the limiting plate with a height not lower than that of the sound insulation board can limit the sound insulation board from falling to the outside of the road, thereby reducing the dangerous situation caused by the broken sound insulation board. There is a gap between the sound insulation board and the limiting plate, which reduces the situation that the limiting plate is broken due to the impact of external force on the sound insulation board from the inside. The gap between the sound insulation board and the limiting plate can be used to fill sound insulation cotton, which further improves the sound insulation effect of the prefabricated baffle.

[0009] Preferably, a plurality of connecting rods are pre-embedded in the road, a plurality of limiting holes are formed in one end of the limiting plate close to the road, one end of each connecting rod extends towards the limiting plate and is inserted into the corresponding limiting hole, and a nut is threadedly connected to the end of each threaded rod away from the road and abuts against the limiting plate.

[0010] By using the above technical scheme, the connecting rods and nuts pre-embedded in the road are used to detachably connect the limiting plate and the road, so that the soundproof cotton can be filled or replaced, and the limiting plate can be easily repaired and replaced.

[0011] Preferably, a fixing plate is fixedly connected to the upper surface of the soundproof plate, and the upper surface of the limiting plate abuts against the lower surface of the fixing plate.

[0012] By using the above technical scheme, the fixing plate seals the upper end opening between the soundproof plate and the limiting plate, and when a plurality of prefabricated baffle plates are arranged along the length direction of the road and assembled to form a guardrail, the prefabricated baffle plates are tightly connected between each other, the soundproof plates at both ends of the length direction of the guardrail are sealed by the concrete between the soundproof plates and the limiting plates, and the soundproof cotton is prevented from being separated from the soundproof plates and the limiting plates.

[0013] Preferably, the locking mechanism comprises a connecting plate placed on the upper surface of the mounting seat, a connecting plate close to the lower surface of the road, and a plurality of threaded rods, each threaded rod penetrating through the connecting plate, the mounting seat, the road and the connecting plate, and each threaded rod being threadedly connected with a nut clamping the connecting plate and the connecting plate.

[0014] By using the above technical scheme, the mounting seat and the road are tightly connected, and the prefabricated baffle plate is transported to the construction site, and then the prefabricated baffle plate and the road are connected.

[0015] Preferably, a reinforcing mechanism is installed on the road, the reinforcing mechanism comprises a reinforcing plate close to the side wall of the soundproof plate away from the road, the lower end of the reinforcing plate is hingedly connected to the road, the upper surface of the road is provided with a communication hole, the lower end of the reinforcing plate is fixedly connected with a supporting rod inserted into the communication hole, the lower end of the supporting rod is fixedly connected with a transmission rod, and one end of the transmission rod abuts against the side of the connecting plate close to the supporting rod.

[0016] By using the above technical scheme, when the inner side of the soundproof plate is subjected to a force, the soundproof plate has a tendency to move towards the outer side of the soundproof plate, at this time the soundproof plate pushes the reinforcing plate, the reinforcing plate drives the supporting rod and the transmission rod to have a tendency to rotate towards the connecting plate. In this way, the transmission rod pushes the connecting plate away from the soundproof plate, and the connecting plate pulls the mounting seat towards the road, so that the nut on the threaded rod is loosened and the mounting seat and the road are separated.

[0017] Preferably, the upper surface of the road is fixedly connected with a fixed rod, the reinforcing plate comprises a reinforcing plate I and a reinforcing plate II, the lower ends of the reinforcing plate I and the reinforcing plate II are fixedly connected with support rods which are inserted into the communication holes, each of the support rods is provided with a hinge hole, the two ends of the fixed rod are inserted into the corresponding hinge holes, each end of the fixed rod is threadedly connected with a nut which clamps the two support rods, and the side surfaces of the reinforcing plate I and the reinforcing plate II which are close to each other are tightly attached to each other.

[0018] By adopting the above technical scheme, when the soundproof plate does not give the reinforcing plate an acting force, the two nuts which are threadedly connected with the fixed rod clamp the two support rods, so that the accidental rotation of the support rods and the reinforcing plate is limited. When the external force applied by the soundproof plate to the reinforcing plate is greater than the friction force of the nut against the support rod in a special case, the transmission rod can give the connecting plate II a pushing force, so as to reinforce the connection between the mounting seat and the road.

[0019] Preferably, the threaded rod is gradually inclined away from the soundproof plate.

[0020] By adopting the above technical scheme, the connecting plate II pulls the threaded rod in the direction away from the soundproof plate, and the inclined threaded rod reduces the breakage of the threaded rod

DETAILED DESCRIPTION

[0037] The following will be described in detail in combination with the accompanying Figures 1-3 The present application will be further described in detail.

[0038] The embodiment of the present application discloses a sound barrier prefabricated baffle. Referring to Figure 1 and Figure 2The sound barrier prefabricated baffle is installed on both sides of the road 1, and comprises a sound insulation board 2 and a mounting seat 3, wherein the mounting seat 3 is located at the lower end of the sound insulation board 2 and is integrally formed with the sound insulation board 2. The mounting seat 3 is connected with a locking mechanism 4, and the mounting seat 3 and the road 1 are fastened and connected through the locking mechanism 4. The side of the sound insulation board 2 away from the road 1 is an outer side, and the side close to the road 1 is an inner side, and the vehicle travels on the inner side of the sound insulation board 2.

[0039] In order to limit the sound insulation board 2 from breaking and falling to the outer side of the sound insulation board 2, a limiting mechanism 5 is arranged on the outer side of the sound insulation board 2, and the lower end of the limiting mechanism 5 is detachably connected with a side wall of the road 1.

[0040] The lower surface of the mounting seat 3 is close to the upper surface of the road 1, and the upper surface of the mounting seat 3 is provided with a plurality of connecting holes 31, and the upper surface of the road 1 is provided with a plurality of connecting holes 11 corresponding in number and position to the connecting holes 31. The locking mechanism 4 comprises a connecting plate 41 and a connecting plate 42, and the connecting plate 41 and the connecting plate 42 are arranged in an upper and lower manner. The lower surface of the connecting plate 41 is close to the upper surface of the mounting seat 3, and the upper surface of the connecting plate 42 is close to the lower surface of the road 1. One connecting hole 31 corresponds to one connecting hole 11, and the locking mechanism 4 further comprises a plurality of threaded rods 43, each of which penetrates the connecting plate 41, the connecting plate 42 and is inserted into one connecting hole 31 and one connecting hole 11.

[0041] The two ends of the threaded rod 43 are threadedly connected with nuts, and the two nuts clamp the connecting plate 41 and the connecting plate 42, so that the connecting plate 41 and the connecting plate 42 clamp the mounting seat 3 and the road 1, and the fastening connection between the mounting seat 3 and the road 1 is completed.

[0042] The limiting mechanism 5 comprises a limiting plate 51, and the limiting plate 51 is the same height as the sound insulation board 2, and the shape of the limiting plate 51 is the same as that of the sound insulation board 2. The lower end of the limiting plate 51 is close to a side wall of the road 1, and a plurality of connecting rods 52 are embedded in the road 1, and one end of each of the plurality of connecting rods 52 extends from the side of the road 1 close to the limiting plate 51. A limiting hole 511 corresponding in number to the connecting rods 52 is formed in one side of the limiting plate 51, and one end of each of the connecting rods 52 is inserted into a corresponding limiting hole 511, and one end of the connecting rod 52 is threadedly connected with a nut abutting against the side of the limiting plate 51.

[0043] When the sound insulation board 2 breaks or falls and the stones fall, the limiting plate 51 can limit the broken sound insulation board 2 or the falling stones to prevent dangerous situations from occurring.

[0044] A receiving cavity 53 is arranged between the limiting plate 51 and the sound insulation plate 2, and the receiving cavity 53 is filled with sound insulation cotton 54. The sound insulation plate 2 is fixedly connected with a fixed plate 55 which is integrally formed with the sound insulation plate 2. The fixed plate 55 extends horizontally towards the limiting plate 51 at one end, and the lower surface of the one end of the fixed plate 55 is tightly attached to the upper surface of the limiting plate 51, and the fixed plate 55 seals the upper end of the receiving cavity 53.

[0045] In order to limit the mounting seat 3 from being separated from the road 1 due to external force, a reinforcing mechanism 6 is arranged on the road 1.

[0046] With reference to Figure 2 and Figure 3 The reinforcing mechanism 6 comprises a reinforcing plate 61 which is arranged between the sound insulation plate 2 and the limiting plate 51 and tightly attached to the outer side of the sound insulation plate 2. The reinforcing plate 61 comprises a reinforcing first plate 611 and a reinforcing second plate 612, and the lower ends of the two reinforcing plates 611 and 612 are integrally formed with support rods 62. The upper surface of the road 1 is provided with communication holes 12 corresponding to the number of the support rods 62, and each support rod 62 is inserted into a corresponding communication hole 12.

[0047] The lower end of each support rod 62 is welded with a transmission rod 63 which extends towards the connecting second plate 42, and one end of each transmission rod 63 is tightly attached to the side wall of the connecting second plate 42 close to the support rod 62. The reinforcing plate 61 is hinged to the road 1, and each communication hole 12 is inclined towards the connecting second plate 42.

[0048] When the sound insulation plate 2 tends to move towards the outside of the sound insulation plate 2 due to external force, the sound insulation plate 2 applies a force to the reinforcing plate 61 to rotate away from the sound insulation plate 2. At this time, the reinforcing plate 61 drives the support rods 62 and the transmission rods 63 to tend to move towards the connecting second plate 42, so that the transmission rods 63 pull the mounting seat 3 away from the sound insulation plate 2 through the locking mechanism 4, thereby limiting the mounting seat 3 from being separated from the road 1.

[0049] Each threaded rod 43 is gradually inclined away from the sound insulation plate 2 from top to bottom, so that the shear force acting on the threaded rod 43 is reduced, and the bending or breaking of the threaded rod 43 due to the force of the transmission rod 63 and the connecting second plate 42 is reduced.

[0050] The upper surface of the road 1 is fixedly connected with a fixed rod 64 equal in number to the prefabricated baffle, and the fixed rod 64 is arranged along the length direction of the mounting base 3. The side wall of each support rod 62 is provided with a hinge hole 621 which transversely penetrates the support rod 62, the fixed rod 64 is located between the support rod 62 connected with the reinforcing one plate 611 and the support rod 62 connected with the reinforcing two plate 612, each end of the fixed rod 64 penetrates the hinge hole 621 in the corresponding support rod 62, and the mutually close surfaces of the reinforcing one plate 611 and the reinforcing two plate 612 are tightly attached to each other. The threaded connection nuts at both ends of the fixed rod 64 are screwed to clamp the two support rods 62.

[0051] When the soundproof board 2 does not exert an external force on the reinforcing plate 61, the two nuts threaded on the fixed rod 64 abut against the corresponding support rod 62 to limit the movement of the support rod 62 and the reinforcing plate 61. When the soundproof board 2 exerts an external force on the reinforcing plate 61, the external force received by the reinforcing plate 61 is easily greater than the frictional force of the nut on the fixed rod 64 to the support rod 62, at this time, the reinforcing rod has a tendency to drive the support rod 62 to rotate relative to the fixed rod 64, and the support rod 62 has a tendency to drive the transmission rod 63 to move the connecting one plate 41.
