At the same time, through the installation and fixation of the auxiliary fixing frame, it is convenient to stably reinforce between the sound-insulating boards, thereby avoiding the safety hazard of the sound-insulating board falling off during use. Although the prior art can achieve quick positioning and installation of the wall panel, when the wall panel needs to be disassembled and replaced, due to the long-term connection between the wall panel and the installation frame, there will be a bonding phenomenon, which will affect the disassembly and replacement efficiency of the wall panel, increase the work burden of the staff, and has poor practicability. Therefore, the dust-absorbing sound insulation wall panel for urban expressways is proposed to solve the above problems well. Content of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0025] The present utility model provides the following technical solutions, a dust-absorbing and sound-insulating wall panel for urban expressways:

[0026] In Embodiment 1, to solve the problem that when the wall panel body 3 needs to be disassembled and replaced, adhesion may occur due to the long-term connection between the wall panel body 3 and the installation frame 1, which will affect the disassembly and replacement efficiency of the wall panel body 3, increase the workload of the staff, and have poor practicability. It is disclosed that: a limit block 9 is slidably installed inside the installation strip 7, and the outer side surface of the limit block 9 is inclined, and the outer end of the limit block 9 penetrates through the installation strip 7 and extends into the installation frame 1. One end of an extrusion spring 10 is connected inside the installation strip 7, and the other end of the extrusion spring 10 is connected to the limit block 9. Pressing rods 8 are symmetrically and slidably installed inside the installation frame 1, and the inner ends of the two pressing rods 8 correspond to the limit block 9.

[0027] As Figures 1 - 6 shown, when the wall panel body 3 is installed inside the installation frame 1 through the two installation strips 7, the bottom of the wall panel body 3 will squeeze the top plate 12 to move downward. At this time, the downward-moving top plate 12 will drive the two support rods 13 to drive the two moving blocks 14 to move outward in position, so as to squeeze and store energy for the two return springs 15. During the process of disassembling and replacing the wall panel body 3, the two return springs 15 that are squeezed and stored with energy will elastically reset the positions of the two moving blocks 14 after extrusion and movement through their own elastic forces, so as to drive the two support rods 13 to squeeze the top plate 12 to move upward in reset, so that the top plate 12 pushes the wall panel body 3 out of the top outside of the installation frame 1 to achieve quick auxiliary disassembly of the wall panel body 3, and the operation is more time-saving and labor-saving.

[0028] In Embodiment 2, different from Embodiment 1, it can realize more convenient installation and positioning of the wall panel body 3, without the need for multiple staff to hold the wall panel body 3 by hand for positioning and installation, improving the installation convenience of the wall panel body 3. It is disclosed that:

[0029] An installation frame 1, and two installation bars 7 slidably installed inside it. Wallboard bodies 3 are connected at the opposite positions of the two installation bars 7, and the wallboard bodies 3 are arranged inside the installation frame 1. At the same time, positioning angle pieces 2 are arranged at the bottom of the installation frame 1. Partition strips 4 are installed on the front side of the wallboard bodies 3, and hollow sound insulation boards 5 are arranged at the opposite positions of the two partition strips 4. The hollow sound insulation boards 5 are installed on the front side of the wallboard bodies 3. At the same time, sound insulation and dust-proof sheets 6 are also arranged on the upper and lower sides of the wallboard bodies 3. The inner side of the bottom of the installation frame 1 is provided with a top plate 12, and above the top plate 12 corresponds to the wallboard body 3, and the width of the top plate 12 is the same as the width of the wallboard body 3.

[0030] The bottom of the top plate 12 is connected with telescopic rods 11, and the two telescopic rods 11 are symmetrically arranged about the vertical center line of the top plate 12. The lower parts of the two telescopic rods 11 are connected with the installation frame 1. A support rod 13 is rotatably installed below the top plate 12, and the two support rods 13 are in an inclined shape. The bottom ends of the two support rods 13 are rotatably connected with a moving block 14. One ends of two return springs 15 are connected inside the installation frame 1, and the other ends of the two return springs 15 are connected with the moving block 14. The two moving blocks 14 are symmetrically slidably installed inside the installation frame 1.

[0031] As Figures 1 - 4 shown, when the wallboard body 3 needs to be positioned and installed, only need to slidably install the wallboard body 3 inside the installation frame 1 through the two installation bars 7. At this time, the two inclined limit blocks 9 will contract and move under the extrusion of the installation frame 1, so that the two limit blocks 9 contract and move into the two installation bars 7. Subsequently, the two compression springs 10 will also automatically pop the two limit blocks 9 into the installation frame 1 through their own elastic forces, so as to limit and fix the position of the installed wallboard body 3, avoiding the phenomenon of loosening and falling off of the wallboard body 3 during later use, and the stability is better.

[0032] When the wallboard body 3 needs to be disassembled and replaced, only need to press the pressing rod 8 to contract and move, so that the pressed and contracted pressing rod 8 squeezes the limit block 9 to contract and move. At this time, the installation frame 1 can be separated from the installation bar 7, and then the wallboard body 3 can be taken out from the inside of the installation frame 1, realizing the quick disassembly and installation of the wallboard body 3, and at the same time reducing the construction burden of the staff, and the operation is more time-saving and labor-saving.
