Description

Technical Field

[0001] The utility model relates to the technical field of road sound insulation equipment, in particular to a sound insulation barrier structure for highways. Background Art

[0002] Sound barrier is an effective noise reduction facility that reduces the impact of noise on the surrounding environment and residents by blocking and absorbing noise. Sound barriers can be made of a variety of materials, such as sound-absorbing materials, sound-insulating materials, etc., and appropriate materials and designs are selected according to actual conditions. At present, when municipal engineering is building roads, sound barriers are installed on the crash barriers on both sides of the road. They are mainly used for sound insulation and noise reduction of highways, elevated composite roads and other noise sources. Existing sound insulation equipment is all integrated. For example, application number 202222595241.8 discloses a sound barrier for use on roads. The sound insulation board is integrated into a single shape and the overall weight is heavy, which increases the difficulty of installation. In addition, this type of barrier cannot flexibly adjust the inclination angle of the barrier according to the height position of the barrier itself, and it is difficult to improve the sound absorption performance, so it needs to be improved. Utility Model Content

[0003] Based on this, it is necessary to provide a noise insulation barrier structure for highways to address the above problems.

[0014] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0015] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0017] like Figures 1 to 3As shown, the highway sound insulation barrier structure comprises a base 1, a column 2 and a plurality of screen bodies 3, the lower ends of the two columns 2 are respectively connected to the two bases 1, and the plurality of screen bodies 3 are installed in parallel and spaced apart between the two columns 2, the screen body 3 is arranged to face the highway side and tilted, and a sealing strip 4 is arranged between two adjacent screen bodies 3, the screen body 3 is hollow and filled with sound-absorbing material, and the screen body 3 is provided with a plurality of muffler holes 31 and ribs 32 facing the highway side, the plurality of muffler holes 31 are arranged linearly side by side, the ribs 32 correspond to each row of muffler holes 31 one by one, and the ribs 32 are located above the muffler holes 31, and the inclination angle of the screen body 3 to the highway side gradually decreases from top to bottom. Specifically, the base 1 and the column 2 are made of stainless steel, with high structural strength and not easy to rust, while the outer shell of the screen body 3 is made of aluminum alloy, with a lightweight design and more labor-saving assembly. The column 2 serves as the carrier of the screen body 3, and the two screen bodies 3 are assembled between the two columns 2 by welding, bolts or clamping. In order to improve the sound insulation, sound absorption and energy absorption, the applicant tilts the screen bodies 3 toward the road side, and the tilt amplitude gradually decreases from top to bottom, because the applicant found that the barrier structure is mostly installed on the cement guardrail 100 on the road side, and the overall height of the cement guardrail 100 is about 60 to 120 cm. The overall height of the barrier structure is relatively high, and the noise emitted by the absorbed car is mostly transmitted from bottom to top. During the absorption process of the vertical screen body 3, the sound waves are easily shielded by the rain shielding structure of the screen body 3 facing the road side, resulting in the sound waves not being able to enter the screen body 3 along the muffler hole 31 and not being absorbed by the sound absorbing material. This is one of the problems of the poor sound absorption performance of the existing barrier. Therefore, the applicant improved the inclination angle of the screen body 3, and in order to prevent the sound waves from passing through the gap between the two screen bodies 3, we installed a sealing strip 4 between the two screen bodies 3 by gluing to ensure that the upper and lower screen bodies 3 fit tightly. It should be noted that in this design, the sound-absorbing material used is glass wool, which is low in cost. In other embodiments, foamed aluminum and the like can also be used, and no specific restrictions are made here. We set ribs 32 and silencer holes 31 on the side of the screen body 3 facing the highway, and each rib 32 is located directly above a row of silencer holes 31. In rainy weather, the ribs 32 can play a role in shielding from rain, and because the screen body 3 is tilted as a whole, the ribs 32 can catch raindrops to prevent rainwater from entering the silencer holes 31 along the surface of the screen body 3, causing the sound-absorbing material to become damp, causing it to stick, no longer fluffy, and the sound absorption performance to decrease, and breeding mold and odor.

[0018] As an optional embodiment, the sealing strip 4 is embedded between the two screen bodies 3 in an inverted V shape. Rainwater that drifts in between the two screen bodies 3 can flow along the sealing strip 4 and out from both ends to avoid water accumulation, which will easily corrode the outer shell of the screen body 3 and breed mosquitoes over time.

[0019] As an optional embodiment, the column body of the column 2 is wrapped with a light guide sheet to reflect light, improve visibility, and enhance warning, thereby attracting the driver's attention.

[0020] like Figures 1-2 The base 1 includes a front clamping plate 11, a rear clamping plate 12 and a locking bolt 13. The upper end of the front clamping plate 11 is provided with an inserting plate 111, and the upper end of the rear clamping plate 12 is correspondingly provided with a slot 121. The inserting plate 111 is inserted into the slot 121 and connected by the locking bolt 13. The column 2 is welded to the slot 121.

[0021] As an optional embodiment, the adjacent side of the front splint 11 and the rear splint 12 has frosted texture to enhance the friction between the connection surface of the base 1 and the cement guardrail to avoid slippage and misalignment of the front splint 11 and the rear splint 12 during assembly.

[0022] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
