[0022] Example 1 This utility model embodiment provides a fully enclosed sound barrier node adjustment device, such as Figures 1 to 8 As shown, it includes a first adjustment device 1 and a second adjustment device 2; wherein, both the first adjustment device 1 and the second adjustment device 2 include a mounting plate 3, a first side plate 4 and a second side plate 5, and the mounting plate 3, the first side plate 4 and the second side plate 5 are perpendicular to each other.
[0023] The mounting plate 3 of the first adjusting device 1 is connected and fixed to one end of the first web plate 81 of the purlin 8 by fasteners 10, and the mounting plate 3 of the second adjusting device 2 is connected and fixed to the other end of the first web plate 81 of the purlin 8 by fasteners 10; the third side plate 82 of the purlin 8 is in contact with the upper surface of the second side plate 5; the first side plates 4 of the first adjusting device 1 and the second adjusting device 2 are respectively connected and fixed to the second web plate 91 of the corresponding curved beam 9 by fasteners 10; the mounting plate 3 is provided with an elongated hole 6 for the fasteners 10 to pass through, and the first side plate 4 is provided with a fixing hole 7 for the fasteners 10 to pass through.
[0024] It should be noted that the cross-section of the purlin 8 of this utility model is roughly C-shaped, and the curved beam 9 is H-shaped. The first adjusting device 1 and the second adjusting device 2 are symmetrically arranged, and the purlin 8 is supported by the second side plate 5. The first side plate 4 has a fixing hole 7 for connecting with the curved beam 9, and the mounting plate 3 has a long hole 6 for adapting and connecting with purlins 8 of different specifications.
[0025] In some embodiments, one end of the mounting plate 3 in the length direction is bent to form a first side plate 4, and one end of the mounting plate 3 in the width direction is bent to form a second side plate 5. The two ends of the mounting plate 3, namely one end in the length direction and one end in the width direction, are bent in the same direction to form the first side plate 4 and the second side plate 5.
[0026] It should be noted that the mounting plate 3 and the first side plate 4 of this utility model are both vertically arranged, and the second side plate 5 is horizontally arranged; one end of the mounting plate 3 in the length direction refers to the end along the horizontal direction, and one end of the mounting plate 3 in the width direction refers to the end along the vertical direction.
[0027] In some implementations, such as Figure 4 and Figure 5 As shown, the mounting plate 3 has an elongated hole 6 extending along its length, and this elongated hole 6 is an oblong hole; the first side plate 4 has two fixing holes 7 spaced apart along its width, and these fixing holes 7 are round holes. The two fixing holes 7 of this utility model are spaced apart along the vertical direction.
[0028] In some embodiments, the length of the elongated hole 6 is greater than 100mm; the wall thickness of the mounting plate 3, the first side plate 4, and the second side plate 5 is 7~9mm. It should be noted that those skilled in the art can specifically set the length of the elongated hole 6 and the wall thickness of the mounting plate 3, the first side plate 4, and the second side plate 5 according to the actual situation, and this utility model does not make specific limitations in this regard.
[0029] In some embodiments, the fastener 10 is a bolt. Obviously, those skilled in the art can also choose the type of fastener 10 according to the actual situation, and this utility model does not make a specific limitation in this regard.
[0030] like Figures 6 to 8 As shown, the two curved beams 9 of this utility model are spaced at a constant distance L. A first adjusting device 1 and a second adjusting device 2 are installed on opposite sides of the two curved beams 9 respectively. Then, the two ends of the purlin 8 are connected to the first adjusting device 1 and the second adjusting device 2 respectively. Figures 6 to 8 The lengths of the purlins 8 vary, among which... Figure 6 The length of the center purlin 8 is L1. Figure 7 The length of the center purlin 8 is L2. Figure 8The length of the purlin 8 is L3, and L2 < L1 < L3. Purlins 8 of different lengths are connected and fixed to different positions of the corresponding elongated holes 6 by fasteners 10.
[0031] This invention enables the transition of purlin 8 spacing from 10mm increments to 100mm increments under the existing model, significantly reducing the variety of purlin 8 types; and facilitating standardized factory production and on-site installation efficiency.
[0032] In use, the fully enclosed sound barrier node adjustment device of this utility model first connects and fixes the first side plate 4 of the first adjustment device 1 to the second web plate 91 of a curved beam 9 using fasteners 10, and connects and fixes the first side plate 4 of the second adjustment device 2 to the second web plate 91 of another curved beam 9 using fasteners 10; then, the two ends of the purlin 8 are placed on the first adjustment device 1 and the second adjustment device 2 and supported by the second side plate 5; the purlin 8 is adjusted to be approximately in the middle position of the two curved beams 9, and then one end of the first web plate 81 of the purlin 8 is connected and fixed to the elongated hole 6 on the first adjustment device 1 using fasteners 10, and the other end of the first web plate 81 of the purlin 8 is connected and fixed to the elongated hole 6 on the second adjustment device 2 using fasteners 10, thus completing the installation operation.
[0033] Example 2 This embodiment provides a fully enclosed sound barrier node adjustment device, such as... Figures 9 to 13 As shown, the difference between this embodiment and Embodiment 1 is that this embodiment also includes a centering component.
[0034] Both the first adjusting device 1 and the second adjusting device 2 are equipped with centering components. The two sets of centering components arranged opposite each other are used to adjust the centering of the purlin 8.
[0035] like Figure 12 and Figure 13 As shown, the centering assembly includes a centering spring 11, a centering plate 12, a plug-in cylinder 13, and a plug-in rod 14. One end of the plug-in cylinder 13 is connected and fixed to the corresponding first side plate 4. The plug-in rod 14 is slidably inserted into the plug-in cylinder 13. One end of the plug-in rod 14 extends out of the plug-in cylinder 13 and is connected and fixed to the centering plate 12. The centering spring 11 is sleeved on the plug-in cylinder 13 and the plug-in rod 14, and both ends of the centering spring 11 are connected and fixed to the first side plate 4 and the centering plate 12, respectively. One side of the centering plate 12 is used to abut against the end of the purlin 8, and the elastic coefficients of the centering springs 11 in the two sets of centering assemblies are the same.
[0036] It should be noted that the two sets of anti-flush components of this utility model have the same structure and are arranged symmetrically. The specifications of the centering springs 11 of the two sets of centering components, such as the elastic coefficient and spring length, are the same. Thus, the two sets of centering components can provide the same elastic force to both ends of the purlin 8, thereby placing the purlin 8 in the middle position of the two curved beams 9 without the need for manual adjustment of the purlin 8 to the middle position, thus improving the installation efficiency.
[0037] In some embodiments, a friction-reducing coating is also included; the upper surface of the second side plate 5 is provided with a friction-reducing coating. The friction-reducing coating of this utility model can be a polytetrafluoroethylene coating, or other friction-reducing coatings, and this utility model does not specifically limit it.
[0038] In use, the fully enclosed sound barrier node adjustment device of this utility model first connects and fixes the first side plate 4 of the first adjustment device 1 to the second web plate 91 of a curved beam 9 using fasteners 10, and then connects and fixes the first side plate 4 of the second adjustment device 2 to the second web plate 91 of another curved beam 9 using fasteners 10. Then, the two ends of the purlin 8 are placed on the first adjustment device 1 and the second adjustment device 2, supported by the second side plate 5. Simultaneously, the two ends of the purlin 8 press against the centering plate 12 and compress the centering spring 11. Due to the specifications of the two sets of centering springs 11... With the same parameters, the compression elastic force of the two sets of centering springs 11 can automatically adjust the purlin 8 to the middle position of the two curved beams 9. In order to avoid the friction affecting the centering adjustment effect, a coating with a low coefficient of friction is applied to the contact surface between the second side plate 5 and the purlin 8 to reduce the sliding friction. Then, one end of the first web plate 81 of the purlin 8 is connected and fixed to the elongated hole 6 on the first adjusting device 1 by fasteners 10, and the other end of the first web plate 81 of the purlin 8 is connected and fixed to the elongated hole 6 on the second adjusting device 2 by fasteners 10, thus completing the installation operation.
[0039] Example 3 This embodiment provides a fully enclosed sound barrier, including the fully enclosed sound barrier node adjustment device, purlin 8, and curved beam 9 as described in Embodiment 1 or Embodiment 2.
[0040] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
