Description

Technical Field

[0001] This utility model relates to the field of road noise barrier technology, and in particular to a modular assembled road noise barrier frame. Background Technology

[0002] In urban traffic noise reduction projects, the road noise barrier frame is the core component that supports the noise insulation panel and ensures structural stability. Its assembly efficiency and adaptability directly affect the project cycle and noise reduction effect.

[0003] Existing road noise barrier frames mostly adopt integral welding or traditional bolt connection structures. During construction, a large amount of welding work or tightening of dense bolts is required on site. This not only requires high skill levels from construction personnel, but is also greatly restricted by weather and site conditions, such as elevated road sections and narrow sidewalks. Although some frames have attempted to be disassembled into units, the lack of standardized design of the connection interfaces and poor compatibility between modules make it inconvenient to assemble the frame easily. This results in long assembly times for a single section, significantly extending the road occupation construction time and affecting traffic flow. Moreover, the non-modular design of traditional frames means that when a part is damaged, the whole frame must be replaced, making it inconvenient to replace individual pieces, resulting in high maintenance costs. Therefore, this utility model proposes a modular assembly road noise barrier frame to solve the above problems. Utility Model Content

[0004] To address the aforementioned issues, this utility model proposes a modular, assembled road noise barrier frame, which solves the problems of inconvenient frame assembly and individual replacement of noise barriers in existing technologies.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a modular assembled road noise barrier frame, including a base plate, positioning pins installed at the four corners of the base plate, a lower mounting seat installed at the top of the base plate, lower crossbars installed on both sides inside the lower mounting seat, a vertical bar installed at the top of the lower mounting seat, an upper mounting seat installed at the top of the vertical bar, upper crossbars installed on both sides inside the upper mounting seat, and a connecting mechanism provided inside the lower mounting seat;

[0006] The connecting mechanism includes a positioning hole, a positioning block, a threaded groove, a threaded rod, and a rotating block. The positioning hole is opened on both sides of the vertical rod, and a positioning block is provided inside the positioning hole. Threaded grooves are opened on both sides of the lower mounting base, and a threaded rod is provided through the threaded groove. One end of the threaded rod is rotatably connected to one end of the positioning block, and a rotating block is installed at the other end of the threaded rod.

[0007] A further improvement is that the positioning hole and the positioning block are mutually adapted to each other, and the positioning hole and the positioning block form a locking structure.

[0008] A further improvement is that: the bottom end of the lower mounting base and the top end of the upper mounting base are provided with guide holes, and guide blocks are provided inside the guide holes, with one end of the guide blocks connected to one end of the vertical rod respectively.

[0009] A further improvement is that the cross-section of the guide hole is larger than the cross-section of the guide block, and the guide hole and the guide block form a sliding structure.

[0010] A further improvement is that: transverse sealing strips are installed on both sides inside the lower and upper crossbars, and longitudinal sealing strips are installed on both sides inside the vertical bar.

[0011] A further improvement is that grooves are provided at both ends of the lower crossbar and at both ends of the lower mounting base, and fixing pins are provided inside the grooves.

[0012] The beneficial effects of this utility model are as follows: By providing a connecting mechanism on the inner side of the lower mounting base, the vertical rod can be easily disassembled and installed by utilizing the mutual cooperation between the positioning holes, positioning blocks, threaded grooves, threaded rods, and rotating blocks of the connecting mechanism. This enables standardized and rapid modular docking without complex procedures, significantly shortening the assembly time of a single section. Partially damaged modules can be replaced individually, reducing maintenance costs and improving the utilization rate of transportation space, thus saving engineering costs. By providing transverse and longitudinal sealing strips, the mutual cooperation between the transverse and longitudinal sealing strips can fill the gaps in the module assembly, block the noise leakage path, improve noise reduction efficiency, and at the same time prevent rainwater and dust from entering the frame, delaying component corrosion and extending service life. It can also buffer module vibration and friction, reduce abnormal noise, and enhance the overall structural sealing and stability. Attached Figure Description

Detailed Implementation

[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a modular, assembled road noise barrier frame, including a base plate 1. Positioning pins 2 are installed at the four corners of the base plate 1. A lower mounting seat 3 is installed at the top of the base plate 1. Lower crossbars 4 are installed on both sides inside the lower mounting seat 3. A vertical bar 5 is installed at the top of the lower mounting seat 3. An upper mounting seat 6 is installed at the top of the vertical bar 5. Upper crossbars 7 are installed on both sides inside the upper mounting seat 6. A connecting mechanism is provided inside the lower mounting seat 3.

[0019] The connecting mechanism includes a positioning hole 13, a positioning block 14, a threaded groove 15, a threaded rod 16, and a rotating block 17. The positioning hole 13 is located on both sides of the vertical rod 5. The positioning block 14 is disposed inside the positioning hole 13. Threaded grooves 15 are located on both sides of the lower mounting base 3. A threaded rod 16 passes through the threaded groove 15. One end of the threaded rod 16 is rotatably connected to one end of the positioning block 14. The rotating block 17 is mounted on the other end of the threaded rod 16. The positioning hole 13 and the positioning block 14 are mutually compatible. The positioning hole 13 and the positioning block 14 form a locking structure. In use, the vertical rod 5 is placed inside the lower mounting base 3. At this time, the wrench is taken out and the rotating block 17 is rotated to move the threaded rod 16, which in turn moves the positioning block 14 to move into the positioning hole 13, thus fixing the position of the vertical rod 5. This allows for standardized and rapid docking of modules without complicated procedures, significantly shortening the assembly time of a single section. Partial damage can be addressed by replacing the module individually, reducing maintenance costs and improving the utilization rate of transportation space, thus saving engineering costs.

[0020] The bottom of the lower mounting base 3 and the top of the upper mounting base 6 are provided with guide holes 11. A guide block 12 is provided inside the guide hole 11. One end of the guide block 12 is connected to one end of the vertical rod 5. The cross-section of the guide hole 11 is larger than the cross-section of the guide block 12. The guide hole 11 and the guide block 12 form a sliding structure. In use, the mutual cooperation between the guide hole 11 and the guide block 12 guides the lower mounting base 3 and the vertical rod 5 during installation, making the lower mounting base 3 and the vertical rod 5 more stable during installation.

[0021] The lower crossbar 4 and the upper crossbar 7 are equipped with transverse sealing strips 8 on both sides inside, and the vertical bar 5 is equipped with longitudinal sealing strips 9 on both sides inside. In use, the cooperation between the transverse sealing strips 8 and the longitudinal sealing strips 9 can fill the gaps in the module assembly, block the noise leakage path, improve the noise reduction efficiency, and at the same time prevent rainwater and dust from entering the frame, delay the corrosion of components, extend the service life, buffer the vibration and friction of the module, reduce abnormal noise, and enhance the overall structural sealing and stability.

[0022] Both ends of the lower crossbar 4 and both ends of the lower mounting base 3 are provided with grooves. The grooves are equipped with fixing pins 10. In use, the fixing pins 10 are used to fix the position of the lower mounting base 3, making the lower mounting base 3 more stable when positioned.

[0023] Working principle: First, the operator uses the positioning pin 2 to fix the base plate 1 in a suitable position. Then, guided by the guide hole 11 and the guide block 12, the vertical rod 5 is placed inside the lower mounting base 3. At this time, the operator takes out a wrench and rotates the rotating block 17 to move the threaded rod 16, which in turn moves the positioning block 14, moving the positioning block 14 into the positioning hole 13 to fix the position of the vertical rod 5. Then, the lower horizontal rod 4 is placed on both sides of the lower mounting base 3, and the position of the lower mounting base 3 is fixed using the fixing pin 10. The sound barrier can be placed inside the lower horizontal bar 4 and the vertical bar 5 for installation. Then, the upper horizontal bar 7 is installed on top of the sound barrier. The upper mounting base 6 is placed between the vertical bar 5 and the upper horizontal bar 7. The position of the upper horizontal bar 7 is fixed using the fixing pin 10. The rotating block 17 is rotated to fix the vertical bar 5 and the upper mounting base 6. When it is necessary to replace a single piece of sound barrier, the upper mounting base 6 and the upper horizontal bar 7 are removed from the top of the sound barrier. At this time, the sound barrier can be pulled out from inside the lower horizontal bar 4 and the vertical bar 5 for replacement.
