Description

Technical Field

[0001] This utility model relates to the field of enclosure structure technology, specifically a noise reduction enclosure structure for municipal road construction. Background Technology

[0002] Sound insulation during municipal road construction aims to create a quieter environment. Building sound insulation achieves this by reducing noise interference. It focuses on blocking noise caused by vibration energy transmitted through the building structure, such as impact noise generated by the operation of mechanical and electrical equipment, the movement of vehicles on the ground or underground, and pile driving operations. To effectively curb the propagation of these noises, vibration isolation measures are usually implemented at the joints of building components. Noise reduction fencing is a device specifically designed to reduce noise pollution during construction. It is commonly found near noise sources such as municipal road construction and building sites. It has the characteristics of absorbing and blocking sound waves, which can effectively reduce the propagation of noise. With scientific design concepts and appropriate material applications, the fencing can create a sound shadow area behind it, thereby reducing the range of noise propagation and reducing its intensity. Existing noise reduction barriers are usually composed of plate-like structures and supports. This structure has certain limitations in transportation and storage. Due to its fixed shape, it cannot be flexibly adjusted, which may require a large amount of space during transportation, leading to increased transportation costs. Therefore, a noise reduction barrier structure for municipal road construction is proposed to address the above problems. Utility Model Content

The noise reduction enclosure assembly 2 includes a wire mesh 21. A sound-insulating cloth 22 is fixedly connected to the front end of the wire mesh 21. A fixing cylinder 23 is fixedly connected to the inner side of the sound-insulating cloth 22. A rotating cylinder 25 is fixedly connected to the upper end of the fixing cylinder 23.

A segment rod 34 is fixedly connected to the bottom end of the folding block 31, and a fourth reserved screw hole 35 and a threaded groove 36 are provided at the lower end of the segment rod 34.

[0017] As a further implementation of this solution, the base frame assembly 1 includes a connecting block 11, a connecting rod 12 fixedly connected to the top of the connecting block 11, a base 14 fixedly connected to the bottom of the connecting block 11, and a protrusion 13 fixedly connected to the front of the connecting block 11. Through the above arrangement, it can be fixed to the ground to form a support. As a further implementation of this solution, the front end of the protrusion 13 is provided with a screw hole, which is vertically aligned with the third reserved screw hole 33 and the screw hole at the front end of the protrusion 13 is aligned with the second reserved screw hole 28. The protrusion 13 and the reinforcing strip 24 are fixedly connected by bolts. With the above settings, it can be fixedly connected with the reinforcing strip 24. The alignment design can make the left and right ends of the reinforcing strip 24 and the left and right ends of the first reserved screw hole 27 aligned vertically after installation, thereby improving the neatness after installation. As a further implementation of this solution, a screw 15 is fixedly connected to the top of the connecting rod 12. The screw 15 is threadedly connected to the threaded groove 36 opened in the segment rod 34. The top of the connecting rod 12 is in close contact with the bottom of the segment rod 34. With the above settings, this installation method is convenient for disassembly and transportation. At the same time, the disassembled structure is easy to arrange, which can reduce the gaps between structures. As a further implementation of this solution, the through hole of the fixing cylinder 23 is aligned with the fourth reserved screw hole 35. The fixing cylinder 23 is fixed to the fourth reserved screw hole 35 of the segment rod 34 by bolts. The wire mesh 21 extends to the middle end of the segment rod 34. The upper and lower ends of the wire mesh 21 and the sound insulation cloth 22 are provided with grooves. The grooves of the wire mesh 21 and the sound insulation cloth 22 are aligned with the connecting block 11 and the folded block 31. Through the above settings, the fixed wire mesh 21 and the sound insulation cloth 22 can present an inclined structure, thereby improving the noise reduction effect. As a further implementation of this solution, the wire mesh 21 and the sound insulation cloth 22 are inclined near the middle. The second reserved screw hole 28 is vertically aligned with the first reserved screw hole 27. The built-in post 26 is inserted into the slot 32. The first reserved screw hole 27 is aligned with the third reserved screw hole 33. The slot 32 is connected to the third reserved screw hole 33. The first reserved screw hole 27 of the built-in post 26 is fixedly connected to the third reserved screw hole 33 of the folded block 31 by bolts. With the above settings, the noise reduction enclosure components 2 are closely fitted to each other after installation, reducing the noise reduction effect due to gaps, and at the same time facilitating the winding of the wire mesh 21 and the sound insulation cloth 22.

[0018] Workflow: During installation, align the front end of the screw 15 with the front end of the threaded groove 36, then rotate the connecting rod 12 to thread the screw 15 into the threaded groove 36. After the number of turns of the thread is adjusted, ensure the wire mesh 21 and the section rod 34 are tightly fitted together. The fourth pre-drilled screw hole 35 and the protrusion 13 are both located at the front end. After the extension frame assembly 3 and the base frame assembly 1 are assembled, insert the built-in column 26 into the slot 32. Secure the built-in column 26 to the folded block 31 with bolts. After both sections of the built-in column 26 are fixed to the folded block 31, align the second pre-drilled screw hole 28 on the reinforcing strip 24 with the threaded hole on the protrusion 13, and secure the reinforcing strip 24 with bolts. The reinforcing bar 24 is fixed to the two protrusions 13, and then the fixing cylinder 23 is aligned with the fourth reserved screw hole 35. The fixing cylinder 23 is fixed to the section rod 34 by bolts. In this way, the middle of the wire mesh 21 and the sound insulation cloth 22 is inclined, which achieves the purpose of tension and improves the stability of use. Then, the built-in column 26 of another noise reduction enclosure component 2 is inserted into the other end of the slot 32 opened in the folded block 31 and fixed by bolts. At this time, the wire mesh 21 and the sound insulation cloth 22 of the two noise reduction enclosure components 2 fit together to reduce the appearance of gaps. At the same time, the folded block 31 and the connecting block 11 block the groove of the sound insulation cloth 22 and the wire mesh 21 to achieve sound isolation. When in use, the wire mesh 21 faces the direction of construction. The wire mesh 21 serves to support and strengthen the structure, improving the toughness of the device. At the same time, the sound insulation cloth 22 serves to reduce noise. Combined with the purpose of the inclined angle design of the wire mesh 21 and the sound insulation cloth 22, this serves to reflect sound, reduce the horizontal outward expansion of sound, and improve the sound noise reduction effect. During storage, firstly, remove the bolts connecting the noise reduction enclosure component 2 to the protrusion 13 and the folded block 31. Then, pull the built-in column 26 out of the slot 32 to separate the noise reduction enclosure component 2 from the base frame component 1 and the extension frame component 3. Next, rotate the rotating drum 25 to roll up the wire mesh 21 and the sound insulation cloth 22. The grooves of the wire mesh 21 and the sound insulation cloth 22 can better match the shape of the protrusions at both ends of the rotating drum 25. Then, rotate the connecting rod 12 to disengage the screw 15 from the threaded groove 36. After disassembly, the noise reduction enclosure component 2, the base frame component 1, and the extension frame component 3 are all strip structures. This reduces the gaps between them during transportation, making it easier to arrange and adjust them flexibly according to the storage space, increasing the load capacity of a single transport, and thus making it suitable for large-area road enclosure work.
