Description

Technical Field

[0001] This application relates to the technical field of environmental protection boards, and specifically relates to a lightweight sound-absorbing board. Background Art

[0002] In traffic and municipal sections such as highways, railways, light rails, and viaducts, sound barriers can effectively reduce the noise generated by passing vehicles and mitigate the impact on the quality of life of residents along the line. These noises can not only cause fatigue to the human auditory system, but may also cause certain harm to the nervous system, digestive system, and eyesight. Sound barriers can reduce the interference of traffic noise on the surrounding environment by blocking and attenuating the propagation of sound waves.

[0003] However, since the sound-absorbing board is usually relatively heavy, with the weight of one panel exceeding 100 kg, two people cannot carry it together and large machinery must be used to carry and install the sound-absorbing board. Moreover, during the construction process, it is necessary to occupy the road for construction, which poses problems such as great construction difficulty, low construction efficiency, and large potential safety hazards. Utility Model Content

[0004] The main purpose of this application is to provide a lightweight sound-absorbing board, aiming to solve the technical problem that the existing sound-absorbing board is inconvenient for installation and construction due to its large weight.

[0028] Referring to the attached Figures 1 to 3 , the embodiments of the present application provide a lightweight sound-absorbing panel, including a panel main body 1. On both side surfaces of the panel main body 1 extending in the length direction, there are respectively provided a fixed groove 6 and a fixed protrusion 5 that can be mutually clamped. As Figure 5 shown, the fixed groove 6 and the fixed protrusion 5 are used to realize the sequential splicing of multiple panel main bodies 1. Of course, in some special environments, in order to increase the light transmittance of the sound barrier, it can also be as Figure 6As shown, the two plate bodies 1 can also have the fixing grooves 6 facing each other, with the acrylic plate 10 engaged in the middle. The fixing grooves 6 can be used to fix the acrylic plate 10, eliminating the need for additional rivets and rubber strip seals for the contact edges, making the installation convenient. In this embodiment, the specifications of the plate body 1 are 2 m in length, 30 cm in width, and 3 cm in thickness, with a single-piece weight of 27 kg, suitable for manual handling. The main component of the plate body 1 is fiber cement board, and the raw materials of the fiber cement board are made of 12% cement, 75% silica fume, 10% fiber, and 3% other additives. It is not difficult to find that by setting the fixing grooves 6 and fixing bumps 5, multiple plate bodies 1 can be assembled, thereby reducing the weight of a single sound-absorbing panel, making it suitable for manual handling. When installing small-sized and light-weight sound-absorbing panels during construction, the use of large machinery can be reduced, the number of times of transporting sound-absorbing panels by trucks can be decreased, materials and labor can be saved, and the cost of sound barrier construction can be reduced. Moreover, the occupied construction area on the road can also be reduced. In addition, the main component of the sound-absorbing panel is fiber cement board, which has properties such as heat insulation, heat preservation, moisture resistance, and flame retardancy. The material is strong, wear-resistant, impact-resistant, and has strong tensile strength, being firm and durable.

[0029] In the above, refer to Figures 1 to 4 As shown, a plurality of sound-absorbing cavities are arranged at equal intervals along the length direction inside the plate body 1. Sound can be reflected and absorbed from each other after entering the sound-absorbing cavities, thereby achieving the sound insulation effect. At the same time, a partition 9 is arranged between adjacent sound-absorbing cavities, and the partition 9 is integrally formed with the plate body 1. In addition, since the sound barrier is in an outdoor environment, especially beside traffic arteries such as highways, railways, and urban main roads, it often needs to face various extreme natural climate conditions, including strong winds and heavy rains. To prevent the sound-absorbing panel from deforming, being damaged, or even breaking, and to avoid the situation where broken fragments smash passing vehicles in strong wind and heavy rain weather, it is necessary to increase the wind resistance of the sound-absorbing panel. For this purpose, jacks are arranged along the length direction of the partition 9. The jacks are holes reserved during the processing of the sound-absorbing panel. After the sound-absorbing panel is formed, steel bars 7 with a diameter of 2 - 3 mm are inserted manually to enhance the strength of the sound-absorbing panel. It is not difficult to find that in this application, the sound-absorbing panel is a hollow structure with a steel bar structure, effectively improving the overall strength and wind resistance, while also effectively reducing the weight of a single sound-absorbing panel, making it suitable for manual handling. After the road is opened to traffic and there is a need to install a sound barrier during construction, since the sound-absorbing panel is suitable for manual handling, the use of machinery can be reduced, avoiding a large amount of occupation and damage to the road surface during the construction process of large machinery. At the same time, the small volume of a single sound-absorbing panel reduces the temporary occupied area at the construction site. After the small-sized sound-absorbing panel is installed conveniently, the construction time is greatly shortened, the time of temporary occupation of the road is reduced, and the road safety is ensured.

[0030] In a preferred embodiment, as Figure 1As shown in the figure, a texture seam 4 is provided on one side surface of the plate body 1. The texture seam 4 is preferably semicircular in cross-section. Based on the design of the texture seam 4, the overall aesthetics of the sound-absorbing panel can be improved, and the rough surface treatment can enhance the sound absorption ability of the sound barrier. At the same time, due to the need for noise reduction, the thickness of the front material of the sound-absorbing panel is greater than that of the back material, and the thickness of the back material is slightly thinner, which can further reduce the weight of the sound-absorbing panel. It should be noted that here, with the absorption cavity 8 as a reference, the thickness of the front material refers to the thickness from the front of the sound-absorbing panel to the absorption cavity 8, and the thickness of the back material refers to the thickness from the back of the sound-absorbing panel to the absorption cavity 8.

[0031] In addition, as Figure 1 and Figure 2 shown, handle holes 2 are symmetrically provided on both sides of the plate body 1. The handle holes 2 are used for manual handling. Fixing holes 3 are provided on both sides of the handle holes 2. The fixing holes 3 are used to fix the sound-absorbing panel to the installation column through positioning pins. During specific installation, the installation column is an H-shaped steel column 11. The handle holes 2 and the fixing holes 3 are both hidden and installed inside the flange of the H-shaped steel column 11, which has no impact on the noise reduction performance.

[0032] Based on the light sound-absorbing panel provided by the embodiment of the present application, as Figure 7 shown, its construction and installation steps are as follows:

[0033] 1. Before construction, it is necessary to conduct a detailed survey of the construction site to understand the topography, traffic conditions, noise source distribution, etc. According to the design requirements of the sound barrier, confirm the overall height, length, material, structure, etc. of the sound barrier.

[0034] 2. First, remove sundries, stones and other obstacles in the construction area of the lower slope on the roadside of the road, set out the line according to the design scheme, and excavate the foundation. The excavation depth, width and shape should meet the design requirements. During the excavation process, attention should be paid to protecting the surrounding environment and underground pipelines to avoid damage.

[0035] 3. After the excavation is completed, clean and level the bottom of the foundation to ensure that there is no sundry and loose soil. Lay a cushion layer on the bottom of the foundation. The cushion layer material is generally gravel, sand and gravel or concrete, etc. Pour the foundation concrete on the cushion layer.

[0036] 4. Embed a flange plate in the foundation concrete and weld an H-shaped steel on the flange plate. During the installation process, it is necessary to ensure the verticality and stability of the column.

[0037] 5. Insert the sound-absorbing panel between the flanges of the H-shaped steel column 11. During the installation process, attention should be paid to the numbering and direction of the plates to ensure their correct installation. The thickness of the sound-absorbing panel is less than the flange spacing of the H-shaped steel column 11, and it can be fixed with spring pieces or screws to ensure that the sound-absorbing panel is tight and firm without loosening, falling off and other phenomena.

[0038] In summary, the lightweight sound-absorbing panel provided by the embodiments of the present application has the following beneficial effects:

[0039] First: Compared with the existing heavy sound-absorbing panels, the sound-absorbing panel provided by the present application reduces the weight of a single sound-absorbing panel by assembling multiple panel bodies. Moreover, the hollow structure also makes the panel body lightweight, enabling manual handling and installation, reducing the use of large machinery and the number of times of transporting the sound-absorbing panel by trucks, saving materials and labor, and reducing the cost of sound barrier construction.

[0040] Second: Due to its light weight and convenient installation, when the sound barrier needs to be installed after the road is opened to traffic, the use of large machinery is reduced, resulting in a smaller construction area on-site, avoiding damage to the road surface during the construction process of large machinery, shortening the construction time, reducing the time of temporary road occupation, and ensuring road safety.

[0041] Third: The sound-absorbing panel provided by the present application has a hollow structure and is made of fiber cement board, with properties such as heat insulation, heat preservation, moisture resistance, and flame retardancy. The material is strong, wear-resistant, impact-resistant, and has strong tensile strength, being durable. At the same time, the addition of steel bars improves the overall strength and wind resistance of the sound-absorbing panel.

[0042] Fourth, the surface of the sound-absorbing panel provided by the present application is provided with texture seams, which can improve the overall aesthetic appearance of the sound-absorbing panel. At the same time, decorative patterns and art paintings can be printed on the surface of the sound-absorbing panel and pasted on the indoor wall for indoor noise reduction, having a good decorative effect and being able to meet the aesthetic needs of different places.

[0043] Fifth, the sound-absorbing panel provided by the present application is relatively thin. The hollow structure design not only meets sound absorption but also saves materials, and steel bars are inserted into the panel to ensure the strength of the sound-absorbing panel.

[0044] Sixth: The ECP panel used in the sound-absorbing panel provided by the present application is an environmentally friendly material. Its production process has low resource consumption, reduces the use of large machinery during construction, does not produce waste water, waste gas or harmful chemical substances during production, reduces environmental pollution, reduces resource consumption, and reduces carbon emissions.

[0045] Seventh: The ECP panel used in the sound-absorbing panel provided by the present application is an environmentally friendly material. In the application process of traditional sound barriers, the selected materials are usually metals, PC, or fiberglass, etc., with relatively high costs, and the sound barriers are applied outdoors and are very prone to aging after long-term exposure to wind, sun, and rain. Compared with the traditional sound barriers, the sound-absorbing panel of the present application has the advantages of low cost, strong wind load resistance, good fire resistance, and simple installation.

[0046] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
