Description

Technical Field

[0001] This utility model belongs to the field of road and bridge construction technology, and relates to a noise reduction device for roads and bridges. Background Technology

[0002] Construction of municipal roads and bridges involves excavation, ramming, and on-site welding, which generate significant noise. This noise is especially noticeable when roads and bridges are being built near residential areas, as prolonged construction noise can disrupt the rest of nearby residents. Therefore, temporary noise barriers need to be installed during road and bridge construction.

[0003] Current noise reduction devices are typically installed by workers carrying sound insulation panels up scaffolding or on a lift until they reach the top of the steel support frame. They then manually insert the panels one by one into the frame. Disassembly requires the same scaffolding or lift. This process is labor-intensive and inconvenient; furthermore, workers standing on scaffolding and leaning out to insert the panels risk falling.

[0004] To address the aforementioned problems, this utility model proposes a noise reduction device for roads and bridges. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model proposes a road and bridge maintenance device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a noise reduction device for roads and bridges includes several vertically arranged mounting pillars and a noise reduction plate installed between two adjacent mounting pillars. The mounting pillars are connected to mounting shields by fasteners. The mounting pillars and the mounting shields cooperate to form a longitudinal mounting groove. The two ends of the noise reduction plate are engaged in the corresponding mounting grooves.

[0007] Furthermore, the mounting support and the mounting cover cooperate to form an H-shaped mounting structure, and the same mounting structure includes two mounting slots.

[0008] Furthermore, the inner wall of the mounting support used to enclose the mounting groove is provided with a first spring sheet protruding from the outer end face.

[0009] Furthermore, a second spring is provided on the sidewalls at both ends of the noise reduction plate at a position corresponding to the first spring. The opening directions of the first spring and the second spring are opposite, with the opening direction of the first spring facing downward.

[0010] Furthermore, the inner wall of the mounting support for surrounding the mounting groove is provided with an L-shaped positioning hook, and the noise reduction plate is provided with a groove for the L-shaped positioning hook to extend into at the corresponding position.

[0011] Furthermore, the mounting shield sidewall is provided with multiple reinforcing beams arranged longitudinally side by side, and the reinforcing beams are arranged toward the mounting support.

[0012] Furthermore, the noise reduction plate has limiting grooves on its two end sidewalls that allow the reinforcing beam to extend into them.

[0013] Furthermore, the mounting support is equipped with a reinforcing longitudinal plate.

[0014] Furthermore, the fastener includes a fastening bolt, and the reinforcing longitudinal plate has a threaded hole that engages with the fastening bolt.

[0015] Furthermore, a bottom mounting plate is provided at the bottom of the mounting support.

[0016] Compared with existing technologies, this invention has the following advantages: In this invention, when installing the noise reduction panel, the panel is pre-hung on the L-shaped positioning hooks in the mounting grooves of two adjacent mounting supports. The reinforcing beam of the mounting cover is inserted into the corresponding limiting groove and mating groove, and the mounting cover is placed on the mounting support. Finally, the installation is completed by screwing the fastening bolts into the corresponding threaded holes. Compared with the traditional method of inserting noise reduction panels from top to bottom, this noise reduction device does not require workers to use scaffolding or lifting equipment for assembly, saving costs and reducing labor intensity; it also reduces the risk of accidents during the installation of the noise reduction panel.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-6 As shown, the technical solution adopted by this utility model is as follows: A noise reduction device for roads and bridges includes several vertically arranged mounting supports 1 and a noise reduction plate 2 installed between two adjacent mounting supports 1. Mounting covers 4 are connected to the mounting supports 1 by fasteners 3. The mounting supports 1 and mounting covers 4 cooperate to form a longitudinal mounting groove 5, and the two ends of the noise reduction plate 2 are engaged in the corresponding mounting grooves 5. In this embodiment, the noise reduction plate 2 is placed vertically between two adjacent mounting supports 1, and then the mounting covers 4 are installed on the mounting supports 1 by fasteners 3. The noise reduction plate 2 is fixed by the clamping of the mounting supports 1 and the mounting covers 4. Compared with the traditional method of inserting the noise reduction plate 2 from top to bottom, this noise reduction device does not require workers to use scaffolding or other tools such as elevators for assembly, saving costs and reducing labor intensity; at the same time, it reduces the risk of accidents to workers when installing the noise reduction plate 2.

[0026] In this embodiment, the mounting column 1 and the mounting cover plate 4 cooperate to form an H-shaped mounting structure, which includes two mounting slots 5. Two adjacent noise reduction panels 2 are installed through the two mounting slots 5 located on the same mounting structure, thus forming a noise reduction enclosure. During installation, two adjacent noise reduction panels 2 are placed vertically in the mounting slots 5 of the corresponding mounting column 1, and then the mounting cover plate 4 is fixed to the mounting column 1 with fasteners 3, thereby fixing the two adjacent noise reduction panels 2, reducing installation difficulty and improving installation efficiency.

[0027] In this embodiment, the inner wall of the mounting support 1 used to enclose the mounting groove 5 is integrally formed with a first spring piece 6 protruding from the outer end face. When the noise reduction plate 2 is installed in the mounting groove 5, the first spring piece 6 tightly abuts against the side walls at both ends of the noise reduction plate 2, thereby limiting the position of the noise reduction plate 2 and ensuring the stability of the noise reduction plate 2 after installation.

[0028] In this embodiment, second spring pieces 7 are provided at positions corresponding to the first spring piece 6 on both sidewalls of the noise reduction plate 2. The opening directions of the first spring piece 6 and the second spring piece 7 are opposite, with the opening of the first spring piece 6 facing downwards. When the noise reduction plate 2 is installed in the mounting groove 5, the first spring piece 6 and the second spring piece 7 cooperate to form a longitudinal limiting structure. Since the opening of the first spring piece 6 faces downwards, when the noise reduction plate 2 moves upwards along the mounting groove 5, the tops of the first spring piece 6 and the second spring piece 7 abut together, so the noise reduction plate 2 cannot detach upwards from the mounting support 1. Furthermore, due to the constraint of the ground below, when encountering strong winds or other situations, the noise reduction plate 2 can remain stable in the mounting groove 5 under the constraint of the ground and the first spring piece 6 and the second spring piece 7, ensuring the stability of the noise reduction plate 2 after installation.

[0029] In this embodiment, an L-shaped positioning hook 8 is welded inside the mounting support 1 used to enclose the mounting groove 5, wherein the hook-shaped part of the L-shaped positioning hook 8 is set upward; a groove 9 is opened at the corresponding position of the noise reduction plate 2 for it to extend into. When the noise reduction plate 2 is installed, the L-shaped positioning hook 8 cooperates with the groove 9 to pre-hang the noise reduction plate 2 on the mounting support 1, reducing the installation difficulty for workers.

[0030] In this embodiment, multiple reinforcing beams 10 are longitudinally welded side-by-side to the sidewall of the mounting shield 4, with the reinforcing beams 10 facing the mounting support 1. The reinforcing beams 10 improve the overall strength of the mounting shield 4, further increasing the stability of the noise reduction device.

[0031] In this embodiment, the noise reduction plate 2 has limiting grooves 11 on both end sidewalls that allow the reinforcing beam 10 to extend into. It should be added that the mounting support 1 has a mating groove at the position corresponding to the limiting groove 11, which also allows the reinforcing beam 10 to extend into. When the noise reduction plate 2 is pre-hung in the mounting groove 5, the reinforcing beam 10 of the mounting cover 4 extends into the corresponding limiting groove 11 and mating groove. Through the cooperation of the reinforcing beam 10, the limiting groove 11, and the mating groove, the noise reduction plate 2 is positioned to ensure the accuracy of subsequent fastener 3 installation; furthermore, the longitudinal movement of the noise reduction plate 2 is restricted.

[0032] In this embodiment, a reinforcing longitudinal plate 12 is welded inside the mounting column 1 to improve the overall strength of the mounting column 1.

[0033] In this embodiment, the fastener 3 includes a fastening bolt, and the reinforcing longitudinal plate 12 has a threaded hole that mates with the thread of the fastening bolt. After the mounting cover 4 is placed on the mounting support 1, the fastening bolt is screwed into the corresponding threaded hole, thereby fixing the mounting cover 4.

[0034] In this embodiment, the bottom of the mounting column 1 is integrally formed with a bottom mounting plate, which is fixed to the preset ground by bolts, thereby fixing the mounting column 1 in place.

[0035] When using this device, firstly, the mounting column 1 is fixed to the preset ground with bolts. Then, the noise reduction plate 2 is hung on the L-shaped positioning hook 8 in the mounting groove 5 of two adjacent mounting columns 1, and the adjacent noise reduction plate 2 is hung on the L-shaped positioning hook 8 of the corresponding mounting column 1. Next, the reinforcing beam 10 of the mounting cover plate 4 is inserted into the corresponding limiting groove 11 and mating groove, and the mounting cover plate 4 is placed on the mounting column 1. Finally, the installation is completed by screwing the fastening bolt into the corresponding threaded hole.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
