DETAILED DESCRIPTION
[0026] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.
[0027] The embodiments of the present application will be described below with reference to the drawings. Figures 1 to 4
[0028] According to an embodiment of the present invention, a prefabricated sound barrier is provided, including barrier units 10 and connecting components 20; multiple barrier units 10 are provided; the connecting components 20 include assembly connectors 21, first snap-fit connectors 22, second snap-fit connectors 23, connecting plates 24, and first fasteners 25; the assembly connectors 21 include a first abutment portion 211, a second abutment portion 212, and a connecting portion 213, the two ends of the connecting portion 213 being connected to the first abutment portion 211 and the second abutment portion 212 respectively, a portion of the connecting portion 213 being disposed between two adjacent barrier units 10, and the first abutment portion 211 and the second abutment portion 212 being disposed on both sides of the barrier unit 10 respectively; two first snap-fit connectors 22 are provided, the two... First snap-fit connectors 22 are spaced apart, and connecting portions 213 are sandwiched between the two first snap-fit connectors 22. The two sides of the first end of the first snap-fit connector 22 abut against the first abutting portion 211 and the barrier unit 10, respectively. The second end of the first snap-fit connector 22 abuts against the side of the second abutting portion 212 near the first abutting portion 211. Two second snap-fit connectors 23 are provided, and the two second snap-fit connectors 23 abut against the two first snap-fit connectors 22, respectively. The second snap-fit connectors 23 abut against the barrier unit 10. Connecting plate 24 is connected to the first snap-fit connectors 22 and abuts against the assembly connector 21. First fastener 25 passes through one of the first snap-fit connectors 22 and the assembly connector 21 and is fastened to the other first snap-fit connector 22.
[0029] The sound barrier of this embodiment is assembled from multiple barrier units 10. Different numbers of assembly units can be selected to assemble the sound barrier according to the needs of different heights and widths, thereby improving the applicability of the prefabricated sound barrier. Through the cooperation of the assembly connector 21, the first snap-fit 22, the second snap-fit 23 and the first fastener 25, the operation is simple and a stable connection between adjacent barrier units 10 is achieved, thereby improving the stability of the prefabricated sound barrier.
[0030] Specifically, such as Figure 1 As shown, the prefabricated sound barrier in this embodiment is assembled from three barrier units 10.
[0031] Of course, in other alternative implementations, the number of barrier units 10 can be selected according to actual needs.
[0032] Specifically, such as Figure 4 As shown, the assembly connector 21 is formed by connecting the first abutting part 211, the second abutting part 212 and the connecting part 213, and the cross section of the assembly connector 21 is "I" shaped.
[0033] It should be noted that the planar dimensions of each barrier unit 10 are no greater than 3m × 2m, in order to control the overall area occupied by the barrier unit 10 and facilitate construction.
[0034] It should be noted that the sound insulation barrier in the related art needs to weld the main components such as beams, columns and supports first, and then install the noise reduction wallboard layer by layer, which has a huge installation workload, and after the noise reduction wallboard is installed, the workload is large, the operation difficulty is high, and the applicability of the sound insulation barrier is poor.
[0035] Therefore, the sound insulation barrier is composed of a plurality of barrier units 10 in an assembled form, and the applicability of the assembled sound insulation barrier is improved by selecting different numbers of assembled units for assembly.
[0036] In one embodiment, as shown in Figure 1 The barrier unit 10 includes a plurality of barrier modules 11, and the plurality of barrier modules 11 are connected in a clamping manner.
[0037] It should be noted that the barrier modules 11 are integrally transported to the site in a box type pre-assembly form by the factory, and are assembled layer by layer according to the height.
[0038] It is worth noting that the plurality of barrier modules 11 are assembled to form the barrier unit 10 in a clamping manner, which simplifies the assembly process of the barrier unit 10 and reduces the on-site construction difficulty and labor cost.
[0039] In one embodiment, as shown in Figure 3 The barrier module 11 includes a sound insulation frame 111 and a noise reduction structure 112, two sound insulation frames 111 are arranged at intervals, and the noise reduction structure 112 is arranged between the two sound insulation frames 111.
[0040] It is worth noting that the noise reduction structure 112 is arranged between the two sound insulation frames 111 arranged at intervals, forming a composite structure of double-layer sound insulation and intermediate noise reduction, which effectively improves the comprehensive noise reduction performance of the sound insulation barrier.
[0041] Specifically, the noise reduction structure 112 is a sound-absorbing porous material.
[0042] It should be noted that in other alternative embodiments, the noise reduction structure 112 can also be selected from sound insulation boards, sound-absorbing cotton and other noise reduction materials.
[0043] In one embodiment, as shown in Figure 1 and Figure 2 The assembled sound insulation barrier further includes a fixed base 30, the fixed base 30 is connected with the first end of the barrier unit 10 away from the connecting assembly 20, and the fixed base 30 is adapted to be connected with the ground 60.
[0044] Specifically, the fixed base 30 is a prestressed concrete pile.
[0045] It is worth noting that the fixed base 30 is connected with the bottom of the barrier unit 10 and fixed to the ground 60, which provides a stable bottom support for the entire assembled sound barrier, effectively disperses the pressure transmitted by the barrier unit 10 to the ground 60, avoids the bottom settlement and inclination caused by the barrier self-weight or external force, and improves the overall structural stability of the sound barrier.
[0046] In one embodiment, as shown in Figure 2 The assembled sound barrier further comprises an anchoring structure 40 connected with the connecting plate 24, and the anchoring structure 40 is adapted to be connected with the ground 60.
[0047] Specifically, the connecting plate 24 is provided with a mounting hole 241, and the anchoring structure 40 is connected with the connecting plate 24 through the mounting hole 241.
[0048] It is worth noting that the anchoring structure 40 is connected with the connecting plate 24 and fixed to the ground 60, which can form a lateral tension support for the barrier unit 10, effectively resist the impact of lateral load such as wind force on the sound barrier, avoid the barrier unit 10 from falling or deforming due to excessive lateral force, and further improve the structural safety of the sound barrier in complex environment.
[0049] Specifically, as shown in Figure 2 The anchoring structure 40 comprises an anchoring pile 41 and a connecting wire 42, the two ends of the connecting wire 42 are respectively connected with the anchoring pile 41 and the connecting plate 24, and the anchoring pile 41 is adapted to be connected with the ground 60.
[0050] Specifically, the connecting wire 42 is a steel strand to ensure the structural strength of the connecting wire 42.
[0051] It should be noted that the sound barrier structure of the related art is a vertical large cantilever structure, and the stress characteristics of the pure bending form will have a large top displacement under the wind load working condition, which is not conducive to the connection of the noise reduction wall panel. At the same time, a large bending moment is formed at the bottom, which requires the foundation width in the vertical barrier length direction to be large enough and the foundation depth to be deep enough to meet the safety requirements of the barrier foundation. Most areas with high wind load need to use a barrier steel frame structure with a large column spacing, which results in a large ground 60 occupied by the support. However, due to the limitation of industrial plant site, the underground pipeline is complex, and it is impossible to excavate a large area of continuous foundation pit to ensure the width requirement of the foundation, which causes difficulties in the construction of the sound barrier foundation, hinders the subsequent installation, and limits the effective application of the barrier structure.
[0052] It is worth noting that the connecting plate 24 and the anchoring pile 41 are connected by the connecting wire 42, which is tensioned and prestressed, thereby tensioning the barrier unit 10 in the height direction and resisting the tensile force of the steel strand transmitted by the wind load, effectively converting the bending moment borne by the foundation, and reducing the difficulty of foundation width and foundation excavation of the barrier unit 10.
[0053] In one embodiment, such as Figure 2 As shown, the connecting line 42 and the barrier unit 10 form an anchorage angle, which is α, satisfying 15°≤α≤30°.
[0054] Specifically, in this embodiment, the anchorage angle α is 20°.
[0055] Of course, in other alternative implementations, the size of the anchorage angle can be adjusted according to the actual situation.
[0056] It should be noted that when α < 15°, the anchoring angle is too small, which will result in insufficient lateral tension of the connecting line 42 on the barrier unit 10, making it difficult to effectively resist lateral loads; when α > 30°, the anchoring angle is too large, which increases the stress on the connecting line 42 and may generate additional vertical pressure on the bottom of the barrier unit 10, affecting the stability of the bottom structure.
[0057] It is worth noting that by limiting the range of the anchoring angle, the anchoring effect is ensured while taking into account the reasonable stress of the connecting line 42 and the barrier unit 10, thus extending the service life of the structure.
[0058] Furthermore, such as Figure 2 As shown, there are two anchoring structures 40, which are symmetrically arranged on both sides of the barrier unit 10.
[0059] It is worth noting that the two symmetrically arranged anchoring structures 40 can provide balanced lateral support for the barrier unit 10, avoid the force imbalance caused by unilateral anchoring, and prevent the barrier unit 10 from tilting or deforming to one side.
[0060] It is worth noting that the prefabricated sound barrier in this embodiment adopts an assembly form, forming a structure with high-rigidity prestressed tension on both sides and compression on the middle barrier unit 10. This can effectively reduce the foundation stress area of the assembly unit area, effectively solve the site size problem, and reduce the amount of civil engineering work.
[0061] In one embodiment, such as Figure 3 As shown, the prefabricated sound barrier also includes an insulation structure 50, which is disposed between the first snap-fit member 22 and the barrier unit 10, and the insulation structure 50 is disposed between the second snap-fit member 23 and the barrier unit 10.
[0062] It should be noted that the first connector 22 and the second connector 23 are in contact with the sound insulation frame 111 of the barrier unit 10. This is a metal-to-metal contact, which can easily cause electrochemical corrosion and affect the structural lifespan.
[0063] It is worth mentioning that by setting the insulating structure 50, the electric conduction path between the metal members is effectively blocked, avoiding the electrochemical corrosion caused by electromagnetic induction or static accumulation, prolonging the service life of the clamping piece and the barrier unit 10.
[0064] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the present application.
