Description

Technical Field

[0001] This utility model relates to the technical field of sound barriers, and in particular to a 3D-printed concrete sound barrier structure based on solid waste recycling. Background Technology

[0002] Noise barriers are noise reduction facilities installed between traffic routes and surrounding sensitive areas. They reduce the impact of traffic noise on the surrounding environment by blocking, absorbing or reflecting the propagation path of sound waves. With the integration of green development concepts and advanced manufacturing technologies, 3D-printed concrete noise barriers based on solid waste recycling have become a new technological direction.

[0003] The sound barrier uses recycled aggregates such as construction waste and industrial waste as the main materials. After optimization of the proportion, it is made into printed concrete and stacked layer by layer by 3D printing equipment, thereby reducing the consumption of natural resources and solid waste pollution.

[0004] In existing technologies, the installation of sound barriers often involves splicing and fixing with a large number of bolts, which makes bolt alignment and tightening during construction time-consuming and the overall installation cycle long. Furthermore, during subsequent maintenance, when replacing damaged screens, the bolts need to be loosened one by one, which not only prolongs the maintenance time but may also cause secondary damage to the surrounding structure due to forced disassembly, increasing operation and maintenance costs and safety risks. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems existing in the current 3D printed concrete sound barrier structure based on solid waste recycling, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a 3D-printed concrete sound barrier structure based on solid waste recycling, which aims to solve the problem that "the installation of sound barriers is mostly done by splicing and fixing with a large number of distributed bolts, which makes the bolt alignment and tightening during construction take a lot of time, resulting in a long overall installation cycle. In addition, during subsequent maintenance, when replacing damaged screens, the bolts need to be loosened one by one, which not only prolongs the maintenance time, but may also cause secondary damage to the surrounding structure due to forced disassembly, increasing operation and maintenance costs and safety risks."

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: including:

[0009] Base;

[0010] A positioning unit is disposed on the base and is used for initial positioning of the sound barrier; a reinforcement component is disposed on the positioning unit and is used for subsequent stabilization of the sound barrier.

[0011] A pushing component is disposed in the positioning unit and is used to move the reinforcement component synchronously with the positioning unit horizontally.

[0012] As a preferred embodiment of the 3D printed concrete sound barrier structure based on solid waste recycling described in this utility model, the positioning unit includes two supports, both of which are fixedly connected to the base. Two sound barrier bodies are engaged within the base and are in close contact with each other. The opposing sides of the two supports are threaded with positioning bolts, and the adjacent ends of the two positioning bolts are fixedly connected with abutment blocks. The two abutment blocks movably penetrate the corresponding supports and contact the two sound barrier bodies.

[0013] As a preferred embodiment of the 3D printed concrete sound barrier structure based on solid waste recycling described in this utility model, the reinforcing component includes multiple connecting slots, which are all opened on the corresponding sound barrier body and are distributed sequentially from top to bottom. Reinforcing plates are movably attached to both sound barrier bodies, and multiple connecting blocks are fixedly connected to both reinforcing plates. The multiple connecting blocks are inserted into the corresponding connecting slots.

The two U-shaped plates are fixedly connected to the corresponding reinforcing plates. The two U-shaped plates are rotatably connected to the corresponding push rings.

[0015] As a preferred embodiment of the 3D printed concrete sound barrier structure based on solid waste recycling described in this utility model, baffles are embedded on both of the supports, and multiple baffles together form a transverse guide.

[0016] As a preferred embodiment of the 3D printed concrete sound barrier structure based on solid waste recycling described in this utility model, a triangular plate is fixedly connected to each of the multiple baffles, and the multiple triangular plates are located on the upper side of the transverse guide.

[0017] As a preferred embodiment of the 3D printed concrete sound barrier structure based on solid waste recycling described in this utility model, both sides of the two main sound barrier bodies are wavy and each has multiple sound-absorbing grooves.

[0018] As a preferred embodiment of the 3D printed concrete sound barrier structure based on solid waste recycling described in this utility model, the top surfaces of both sound barrier bodies are semi-circular, and both reinforcing plates are matched with the sound barrier bodies.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein.

[0034] Example 1

[0035] Reference Figures 1 to 3 This is the first embodiment of the present utility model, which provides the following achievable effects:

[0036] Base 100;

[0037] Positioning unit 200 is disposed on base 100 and is used for initial positioning of the sound barrier. Reinforcing component 300 is disposed on positioning unit 200 and is used for subsequent stabilization of the sound barrier.

[0038] The pushing component 400 is disposed in the positioning unit 200 and is used to move the reinforcement component 300 synchronously with the positioning unit 200 horizontally.

[0039] During use, the positioning unit 200 achieves initial accurate alignment of the sound barrier, reducing manual calibration errors. The reinforcement component 300 strengthens the connection strength of the sound barrier through multiple fastening structures, resisting long-term wind and rain loads and vehicle impacts. Together with the pushing component 400, it makes fine-tuning adjustments to the horizontal position during the reinforcement process, ensuring a tight fit between the reinforcement component 300 and the sound barrier. This avoids the risk of loosening due to misalignment during installation, effectively shortening the construction cycle and improving the efficiency of later maintenance.

[0040] Example 2

[0041] Reference Figures 1 to 3 This is the second embodiment of the present invention, which differs from the previous embodiment in that:

[0042] The positioning unit 200 includes two brackets 201, both of which are fixedly connected to the base 100. Two sound barrier bodies 202 are engaged within the base 100 and are in close contact with each other. The sides of the two brackets 201 that are far apart from each other are threaded with positioning bolts 203. The ends of the two positioning bolts 203 that are close to each other are fixedly connected with abutment blocks 204. The two abutment blocks 204 move through the corresponding brackets 201 and contact the two sound barrier bodies 202.

[0043] Stable support is provided by the fixed connection between the two side brackets 201 and the base 100, while the sound barrier body 202 is engaged in the base 100 to achieve initial fixation. Rotating the positioning bolt 203 can drive the abutment block 204 to effectively abut against the sound barrier body 202. The threaded drive ensures that the positioning force is controllable and stable, avoiding loosening and displacement, greatly simplifying the installation process and reducing the time spent on manual calibration. At the same time, by applying pressure symmetrically on both sides, the sound barrier body 202 is subjected to uniform force, improving the wind load and vibration stability.

[0044] The main body of the sound barrier 202 is a 3D printed concrete sound barrier based on solid waste recycling. It uses solid waste such as construction waste and slag as the main aggregates and achieves integrated molding of complex structures through layer-by-layer stacking. This is an existing technology and will not be elaborated on in this article.

[0045] Specifically, the reinforcement component 300 includes multiple connecting slots 301, which are all opened on the corresponding sound barrier body 202 and are distributed from top to bottom. Reinforcing plates 302 are movably attached to both sound barrier bodies 202, and multiple connecting blocks 303 are fixedly connected to both reinforcing plates 302. The multiple connecting blocks 303 are all inserted into the corresponding connecting slots 301.

[0046] Multiple vertically distributed connecting slots 301 and connecting blocks 303 are inserted and matched to form a three-dimensional reinforcement network. After the reinforcement plate 302 is attached to the sound barrier body 202, the connecting blocks 303 can be embedded in the connecting slots 301 to achieve dual longitudinal and lateral limiting, which greatly improves the structural deformation resistance. The interlocking of the slots and blocks disperses the load, enhances the overall rigidity of the sound barrier body 202, and is easy to install without complicated tools, effectively extending its service life.

[0047] Specifically, the pushing assembly 400 includes a push ring 401, which is threadedly connected to the positioning bolt 203. Guide rods 402 are fixedly connected to the inner walls of the two brackets 201. Two U-shaped plates 403 are slidably connected to the multiple guide rods 402 respectively. The two U-shaped plates 403 are fixedly connected to the corresponding reinforcing plates 302. The two U-shaped plates 403 are rotatably connected to the corresponding push rings 401.

[0048] In use, power is transmitted through the threaded connection between the push ring 401 and the positioning bolt 203. Rotating the push ring 401 can drive the U-shaped plate 403 to slide smoothly along the guide rod 402, so that the reinforcing plate 302 is close to the sound barrier body 202. The guide rod 402 guides and ensures that the movement trajectory is stable and avoids deviation. The rotational connection between the U-shaped plate 403 and the push ring 401 eliminates the jamming of the threaded transmission, improves the insertion accuracy of the connecting block 303 and the connecting groove 301, and enhances the overall stability.

[0049] Example 3

[0050] Reference Figures 1 to 3 This is the third embodiment of the present invention, which differs from the previous embodiment in that:

[0051] Both brackets 201 are fitted with baffles 2011, and the baffles 2011 together form a transverse guide.

[0052] The transverse guide formed by the fitting of the baffle 2011 provides auxiliary guidance for the installation of the sound barrier body 202, quickly corrects transverse position deviations, simplifies the alignment process, reduces the time spent on manual adjustments, and ensures that the sound barrier body 202 fits tightly.

[0053] Specifically, multiple baffles 2011 are fixedly connected with triangular plates 2012, and the multiple triangular plates 2012 are located on the upper side of the transverse guide.

[0054] The triangular plate 2012 is located on the upper side of the transverse guide opening, forming an inclined guide surface to prevent rainwater from entering the bracket 201 and accelerating the damage to the parts.

[0055] Specifically, both sides of the two sound barrier bodies 202 are wavy and each has multiple sound-absorbing grooves 2021.

[0056] The wave-shaped sound barrier body 202 has an active noise reduction effect, extends service life, and multiple sound-absorbing grooves 2021 on the surface dissipate sound wave energy through air friction, enhancing the absorption effect of high-frequency noise.

[0057] Specifically, the top surfaces of both sound barrier bodies 202 are semi-circular structures, and both reinforcing plates 302 are matched with the sound barrier bodies 202.

[0058] When in use, the semi-circular top surface of the main body 202 of the sound barrier is set to reduce the impact of wind load.

[0059] During use, the two sound barrier bodies 202 are engaged within the base 100, ensuring a tight fit. By rotating the positioning bolt 203 on the outside of the bracket 201, the threaded drive causes the contact block 204 to tightly contact the sound barrier body 202, completing the initial positioning. During rotation, the positioning bolt 203 drives the push ring 401, using threaded thrust to smoothly slide the U-shaped plate 403 along the guide rod 402, simultaneously pushing the reinforcing plate 302 closer to the sound barrier body 202. At this point, the connecting block 303 on the reinforcing plate 302 is precisely inserted into the connecting groove 301 of the sound barrier body 202. Through the cooperation of multiple vertically distributed groove blocks, a longitudinal alignment is formed with... The horizontal double fixation significantly improves the overall structure's wind load resistance. Conversely, the main body 202 of the sound barrier can be disassembled and maintained by turning the positioning bolts 203 in the opposite direction, which is convenient and quick. Only the positioning bolts 203 on both sides need to be operated. The baffle 2011 on the inner wall of the bracket 201 forms a horizontal guide, and the triangular plate 2012 prevents rainwater from corroding the internal parts. The wave-shaped design of the main body 202 of the sound barrier has an active noise reduction effect, extending its service life. In addition, multiple sound-absorbing grooves 2021 on the surface dissipate sound wave energy through air friction, enhancing the high-frequency noise absorption effect. The semi-circular top surface of the main body 202 of the sound barrier reduces the impact of wind load.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
