Description

Technical Field

[0001] The utility model relates to the technical field of highway protection, in particular to a sound barrier which is convenient for maintenance. Background Technique

[0002] A sound barrier is a facility inserted between a sound source and a receiver, which can cause a significant additional attenuation of sound wave propagation, thereby reducing the noise impact in a certain area where the receiver is located. It is mainly used for sound insulation and noise reduction of highways, expressways, elevated composite roads and other noise sources.

[0003] The existing sound barrier mainly consists of columns and sound insulation boards. The columns adopt I-beams, and the sound insulation boards are stuck in the grooves between adjacent two columns. When installing this kind of sound barrier, the installers need to be lifted to the top of the columns, and the sound insulation boards are lifted by a crane or a forklift, and then the installers put the sound insulation boards into the space between the two columns one by one for installation. This requires working at heights and there are potential safety hazards. At the same time, when a damaged sound insulation board needs to be replaced in the later stage, all the sound insulation boards above the damaged one need to be removed before replacement, which results in high later maintenance costs and low maintenance efficiency.

[0004] Based on this, the present application provides a sound barrier that can effectively reduce the working height and is also convenient for later maintenance. Content of the Utility Model

[0027] Embodiment 1

[0028] As shown in the attached Figure 1As shown in the figure, this embodiment provides a sound barrier that is easy to maintain, including multiple columns 1, multiple sound insulation boards 2 installed between adjacent columns, and multiple pressing plates 3 for pressing the sound insulation boards against the columns.

[0029] As shown in the attached Figure 2 figure, the column 1 includes a back plate 1.1 and a chute 1.2 provided in the middle of the back plate and perpendicular to it. A tie plate 1.3 is provided in the chute 1.2. The tie plate 1.3 is used to tie the pressing plate to achieve the fixation of the pressing plate; the pressing plate 3 is movably arranged in the chute 1.2, and the pressing plate 3 is fixed by being threadedly connected to the tie plate 1.3 through a self-tapping screw 4.

[0030] When the sound insulation board is specifically installed: the sound insulation board is placed between two columns, and then both ends are pressed by multiple pressing plates, and are fixed by passing self-tapping screws through the pressing plates and screwing them into the tie plates in the chute. This installation method of the sound insulation board realizes its front installation, without the need to insert from the top of the column. Only the sound insulation board located at the top of the column needs to be installed with the assistance of a stool, etc., which can greatly reduce the safety risks of installers due to working at heights. At the same time, when the sound insulation board needs to be maintained in the later stage, directly disassembling and assembling the sound insulation board from the front can greatly improve the maintenance efficiency, thereby significantly reducing the maintenance cost.

[0031] Preferably, as shown in the attached Figure 2 figure, the tie plate 1.3 is horizontally arranged in the chute 1.2, and an opening groove is provided in the middle of the tie plate 1.3. The width of the opening groove is smaller than the outer diameter of the self-tapping screw. This design makes it very easy for the self-tapping screw to penetrate into the tie plate, reducing the installation difficulty.

[0032] Preferably, as shown in the attached Figure 2 figure, the pressing plate 3 includes a panel 3.1 and a sleeve 3.2 provided in the middle of the panel. The self-tapping screw 4 passes through the pressing plate 3 from the sleeve 3.2.

[0033] Preferably, as shown in the attached Figure 2 figure, the rod part of the self-tapping screw 4 is successively provided with a smooth rod area 4.1, a self-tapping thread area 4.2, and a cutting area 4.3 from bottom to top. A circlip groove is provided in the smooth rod area 4.1 near the self-tapping thread area. After the self-tapping screw 4 passes through the pressing plate 3, it is limited by a circlip 5 being snapped into the circlip groove. This design makes the self-tapping screw and the pressing plate assembled into one body, and there will be no problem of the self-tapping screw coming out and being lost.

[0034] Preferably, as shown in the attached Figure 2 figure, both ends of the panel 3.1 are provided with a sunken structure, and a rubber pad 3.3 is provided on the surface of the panel in contact with the sound insulation board 2. Since the thickness of the sound insulation board is smaller than the distance between the back plate of the column and the panel of the pressing plate, this design can ensure that the pressing plate presses the sound insulation board.

[0035] Embodiment Two

[0036] Based on the first embodiment, as shown in the appendix Figure 2 As shown, in this embodiment, a flange plate 3.4 is further provided at the top of the sleeve 3.2 of the pressing plate 3, and a barb 1.4 for preventing the pressing plate from slipping out is provided in the chute 1.2 of the column 1. This design of this embodiment can effectively prevent the pressing plate from slipping out of the column.

[0037] Embodiment Three

[0038] Based on the second embodiment, as shown in the appendix Figure 2 As shown, a spring 6 is further sleeved on the sleeve part above the flange plate 3.4. The spring 6 is fixedly connected to the flange plate 3.4, and the other end of the spring 6 abuts against the tie plate 1.3. This design of this embodiment enables the pressing plate to loosen the sound insulation board under the action of the spring after the self-tapping screw is screwed out of the tie plate, and the sound insulation board can be taken out by moving the pressing plate.

[0039] Embodiment Four

[0040] Based on any of the above embodiments, as shown in the appendix Figure 1 As shown, in this embodiment, a top cross beam 7 for connecting all columns is further provided at the top of the column 1. The top cross beam can tie the columns together to form an integral skeleton for installing the sound insulation board.

[0041] Preferably, the top cross beam 7 of this embodiment is preferably a channel steel with an upward opening, and a sound absorber 8 is further provided in the top cross beam. The sound absorber can be made of porous sound absorption materials, such as: mineral wool, glass wool, felt, wood wool sound absorption board and other porous materials, which have good medium and high frequency absorption. When there is an air layer behind, it can also absorb low frequency.

[0042] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
