Description

Technical Field

[0001] This utility model relates to the field of sound barrier technology, and in particular to a sound barrier joint interlocking structure. Background Technology

[0002] A sound barrier is a facility specifically designed for sound insulation and noise reduction. By inserting an obstacle between the sound source and the receiver, it significantly attenuates the propagation of sound waves, thereby reducing the noise impact in a specific area. It is widely used near noise sources such as roads and industrial plants, and features efficient construction, long lifespan, and recyclability.

[0003] Existing sound barriers are generally fixed to the erected columns by fixing bolts. Since the fixing bolts are exposed to the outside environment for a long time, they are easily affected by oxygen and moisture in the air and will rust, which will easily cause the sound barrier to loosen, resulting in the sound barrier tilting and the gaps between the sound barriers to increase, thus reducing the sound insulation and noise reduction effect of the sound barrier. To address this, we provide a sound barrier joint interlocking structure. Utility Model Content

[0004] To address the problems mentioned above, such as the tendency of existing sound barriers to skew due to corrosion of fixing bolts and the widening of gaps between sound barriers, this invention provides a sound barrier joint interlocking structure.

[0005] This utility model is achieved by the following technical solution: a sound barrier joint interlocking structure, including two sets of columns, four sets of sound barrier bodies are arranged between the two sets of columns, eight sets of support seats are symmetrically fixedly connected to one side of each column, the support seats are provided with placement grooves, and placement protrusions are provided inside the placement grooves and are fixedly connected to the sound barrier bodies on the same side.

[0006] As a further improvement to the above solution, the size of the placement groove decreases from top to bottom.

[0007] As a further improvement to the above scheme, the size of the placement bump decreases from top to bottom.

[0008] As a further improvement to the above solution, both the support base and the placement protrusion are provided with screw holes, and the internal threads of the two sets of screw holes on the same side are connected to the same fixing bolt.

[0009] As a further improvement to the above solution, except that the bottom of the lowest part of the sound barrier body is fixedly connected with tenons at equal intervals, and except that the top of the highest part of the sound barrier body is provided with mortises at equal intervals, and the size of the mortises matches the size of the tenons.

[0010] As a further improvement to the above solution, except for the support base at the bottom, there are notches, and the size of the notches decreases from top to bottom.

[0011] As a further improvement to the above solution, the bottom of the column is fixedly connected to a mounting base, and the mounting base is evenly provided with expansion screw holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model supports the sound barrier body by placing the placement protrusion on the sound barrier body into the matching placement groove. This not only facilitates the fixing of the sound barrier body, but also prevents the sound barrier body from tilting when the fixing bolts rust. This effectively ensures the sound insulation and noise reduction effect of the sound barrier body and is highly practical.

[0014] 2. The tight interlocking between the tenon and the mortise provides good stability for the connection between two adjacent sound barrier bodies. Even after long-term use or when subjected to external impact, it will not easily loosen or deform, further ensuring the sound insulation and noise reduction effect of the sound barrier body.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] Example 1:

[0022] Please combine Figs. 1-3This embodiment of a sound barrier joint interlocking structure includes two sets of columns 1, with four sets of sound barrier bodies 2 disposed between the two sets of columns 1. Eight sets of support seats 3 are symmetrically and equidistantly fixed to one side of each column 1. Each support seat 3 has a placement groove 4, and a placement protrusion 5 is disposed inside the placement groove 4 and fixedly connected to the sound barrier body 2 on the same side. The size of the placement groove 4 decreases from top to bottom, as does the size of the placement protrusion 5. Except for the lowest support seat 3, each support seat 3 has a notch, the size of which decreases from top to bottom, to prevent the upper support seats 3 from obstructing the insertion of the sound barrier body 2 layer by layer. The support base 3 and the placement protrusion 5 are both provided with screw holes 6. The internal threads of the two sets of screw holes 6 on the same side are connected to the same fixing bolt 7, which can connect and fix the sound barrier body 2 to the column 1. Except for the bottom of the lowest sound barrier body 2, tenons 8 are fixedly connected at equal intervals. Except for the top of the highest sound barrier body 2, mortises 9 are provided at equal intervals, and the size of the mortises 9 matches the size of the tenons 8. Through the tight engagement between the tenons 8 and the mortises 9, good stability is provided for the connection between the two adjacent sets of sound barrier bodies 2. Even if it is used for a long time or subjected to external impact, it will not easily loosen or deform, thus ensuring the sound insulation and noise reduction effect of the sound barrier body 2.

[0023] The implementation principle of the sound barrier joint interlocking structure in this embodiment is as follows: First, two sets of columns 1 are installed and fixed. Then, the bottom sound barrier body 2 is placed between the two sets of columns 1 and slowly lowered. Since the upper support 3 has a notch, and the size of the notch decreases continuously, it will not hinder the movement of the protrusion 5 on the bottom sound barrier body 2. When the protrusion 5 on the bottom sound barrier body 2 is placed in the placement groove 4 on the bottom support 3, the fixing bolt 7 is screwed into the screw hole 6 and tightened to complete the installation of the bottom sound barrier body 2. Finally, the other sound barrier bodies 2 are installed and fixed in sequence by placing the placement protrusion 5 on the sound barrier body 2 into the matching placement groove. In section 4, the sound barrier body 2 can be supported, which not only facilitates the fixing of the sound barrier body 2, but also prevents the sound barrier body 2 from tilting when the fixing bolts 7 rust, effectively ensuring the sound insulation and noise reduction effect of the sound barrier body 2. When all other sound barrier bodies 2 are installed, the tenon 8 on the upper sound barrier body 2 will be fully inserted into the mortise 9 on the lower sound barrier body 2. The tight engagement between the tenon 8 and the mortise 9 provides good stability for the connection between the two adjacent sound barrier bodies 2. Even if it is used for a long time or subjected to external impact, it will not easily loosen or deform, further ensuring the sound insulation and noise reduction effect of the sound barrier body 2. Conversely, the sound barrier bodies 2 can be removed one by one.

[0024] Example 2:

[0025] Based on Embodiment 1, this embodiment is further improved in that: the bottom of the column 1 is fixedly connected to the mounting base 10, and the mounting base 10 is evenly provided with expansion screw holes 11 to facilitate the fixing of the column 1.

[0026] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
