Description

Technical Field

[0001] This utility model relates to the field of environmental engineering technology, and in particular to a foldable outdoor soundproof barrier. Background Technology

[0002] Outdoor noise barriers are engineering facilities used to isolate, absorb, or reflect noise. They are typically made of sound-absorbing materials such as metal plates, sound-absorbing cotton, or transparent acrylic and are installed between construction sites and residential areas, schools, and hospitals to reduce noise transmission.

[0003] Outdoor noise barriers are mainly divided into two categories: fixed and movable. Fixed outdoor noise barriers are usually permanently installed using concrete or steel structures, suitable for long-term noise control, but they have the disadvantages of being immovable and costly. Movable noise barriers are made of lightweight modular components, which are easy to assemble, disassemble and reuse, offering high flexibility and lower cost, making them more suitable for short-term or temporary noise control needs.

[0004] Existing movable outdoor noise barriers, such as the utility model patent with patent application number 2019211920119, disclose a foldable sound-absorbing and insulating barrier. Three fixed connecting columns are provided on one outer surface of the outer frame of the barrier, and three fixed connecting seats are also provided on one outer surface of the outer frame. An upper support crossbar is provided inside the outer frame, with a first sound-absorbing plate above the upper support crossbar and a second sound-absorbing plate below the upper support crossbar. The second sound-absorbing plate is equipped with… Two, a first limiting rod is provided on one side of the second sound-absorbing plate, the first limiting rod is fitted with a rubber sleeve, and there are three first limiting rods. A second limiting rod is provided on the other side of the second sound-absorbing plate, the second limiting rod is fitted with a rubber sleeve, and there are three second limiting rods. A lower support crossbar is provided below the second sound-absorbing plate. A spring fixing seat is provided on the outer surface of the lower support crossbar, and there are four spring fixing seats. A return spring is provided at one end of the spring fixing seat, and a spring positioning post is fitted inside one end of the return spring.

[0005] However, during the construction of urban rail transit, the construction interface is usually dynamic, the height of the noise source is not fixed, and the distribution of surrounding sensitive points is complex. Only two folded and hinged sound-absorbing panels cannot meet the requirements of precise noise reduction for high-altitude construction. Utility Model Content

[0006] To address the problems mentioned above, this invention provides a foldable outdoor soundproof barrier whose height and width are flexibly adjustable, adapting to the noise reduction needs of various construction environments.

[0007] The solution adopted by this utility model to solve its technical problem is: a foldable outdoor soundproof barrier, comprising several sound insulation panels, wherein a hinge is installed between every two sound insulation panels;

[0008] The hinge arms on both sides of the hinge are provided with mounting grooves, and the sound insulation plate is inserted into and fixed in the mounting grooves.

[0009] The hinge is provided with a fixing component; the sound insulation panel is provided with a fixed base.

[0010] Furthermore, the hinge is a hinge-type hinge.

[0011] Furthermore, the surface of the fixed base is covered with a sound-absorbing panel.

[0012] Furthermore, rubber pads are provided on the sides of the sound insulation panels.

[0013] Furthermore, the fixing member is U-shaped, and its two ends are respectively fixed to the hinge arms at both ends of the hinge member.

[0014] Furthermore, a sealing gasket is provided on the contact surface between the fixing member and the hinge arm.

[0015] Furthermore, a connecting ear is provided on one side of the sound insulation panel.

[0016] Furthermore, a T-shaped reflector is provided on the top of the sound insulation panel.

[0017] In summary, the beneficial effects of this utility model are as follows:

[0018] (1) A hinge-type hinge is used to connect two sound insulation panels. The hinge arm has mounting grooves on both sides, and the sound insulation panels are inserted and fixed. The hinge of this application can be produced and separated separately and can be continuously stacked on the sound insulation panels, thereby greatly changing the height of the sound barrier. In addition, the hinge structure allows multiple sound insulation panels to be folded and stored, which can greatly reduce the space occupied and is suitable for construction scenarios with frequent movement.

[0019] (2) A connecting ear is provided on one side of the sound insulation panel, which can be used to splice more sound insulation panels to adapt to different site requirements. At the same time, the connecting ear can be used to install cables to improve the wind resistance of the sound barrier.

[0020] (3) A T-shaped reflector is installed on the top of the sound insulation panel, which solves the problem of sound wave diffraction at the top of the traditional vertical barrier and improves the overall sound insulation of the soundproof barrier.

[0021] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0026] To make the content of this utility model easier to understand, the present utility model will be further described below with reference to specific embodiments and accompanying drawings.

[0027] It should be noted that the terms "center," "upper," "lower," "front," "rear," "left," "right," "inner," and "outer" used herein to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Unless otherwise stated, "a plurality of" means two or more.

[0028] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figures 1 to 3As shown, a foldable outdoor soundproof barrier includes two soundproof panels 1, with a hinge 2 installed between each pair of soundproof panels 1. The hinge arms on both sides of the hinge 2 are provided with mounting grooves, and the soundproof panels 1 are inserted into and fixed to the mounting grooves by screws. A fixing member 3 is provided on the hinge 2. The soundproof panels 1 are equipped with a fixing base 4. The soundproof panels include an outermost aluminum alloy plate layer, an inner rock wool layer, and a water-based damping layer. The outer surface of the rock wool layer is also coated with a waterproof layer.

[0030] In this embodiment, the hinge 2 is a hinge-type hinge. Optionally, damping elements can be integrated into the hinge arms at both ends of the hinge 2, and a groove can be provided at the bottom of the mounting slot of the hinge 2, with the damping element installed inside the groove. Further, the damping element can be a rubber pad, a silicone buffer block, or a polyurethane shock-absorbing pad, and can be fixed in the groove by adhesive bonding. With the above solution, after the sound insulation plate 1 is inserted into the mounting slot, its edge can contact the damping element at the bottom, reducing vibration transmission and lowering metal-on-metal collision noise. Optionally, a shock-absorbing pad can be provided in the mounting slot of this embodiment, which can fill the gap between the mounting slot and the sound insulation plate 1, blocking the sound wave leakage path.

[0031] Furthermore, the hinge shaft of the hinge-type hinge member 2 in this embodiment may be integrated with a miniature rotary damper, such as a gear damper or a hydraulic damper, so as to generate resistance when the sound insulation plate 1 is folded, so that the hinge arm moves slowly and avoids it closing quickly.

[0032] like Figure 3 As shown, in this embodiment, the sound insulation panel 1, the fixed base 4, the fixing component 3, and the hinge component 2 can all be manufactured and separated separately. The sound insulation panel 1 is provided with a connecting ear on one side, and can be assembled and continuously stacked to form sound-absorbing barriers of different heights and widths, thereby adapting to the sound-absorbing needs of various construction environments. After removing the fixing component 3, the fixed base 4, and the T-shaped reflector 5, the two sound insulation panels 1 can be folded towards the side without the connecting ear, which facilitates construction transfer and storage, saves installation time, and improves installation efficiency.

[0033] The fixed base 4 in this embodiment is made of concrete and its surface is covered with a sound-absorbing panel. The sound-absorbing panel is made of rubber material, which can absorb noise reflected from the ground and increase the friction of the fixed base 4 to prevent it from shifting.

[0034] In this embodiment, the four sides of the sound insulation panel 1 are provided with rubber pads. The rubber pads can fill the seams generated when the left and right sound insulation panels 1 are assembled, and prevent sound waves from leaking from the sides.

[0035] like Figure 1As shown, the U-shaped fixing member 3 spans the hinge arms on both sides of the hinge member 2. The two ends of the fixing member 3 are fixed to the hinge arms at both ends of the hinge member 2 by screws. The hinge member 2 is fixed in a 180° unfolded state by the above scheme. In this embodiment, the contact surface between the fixing member 3 and the hinge arm is provided with a sealing gasket, which can absorb high-frequency vibration noise between the fixing member 3 and the sound insulation plate 1.

[0036] like Figure 2 As shown, a T-shaped reflector 5 is configured on the top of the sound insulation panel 1. The T-shaped extension of the reflector 5 can reflect high-frequency noise upwards, reducing the sound energy of high-frequency noise crossing the barrier. At the same time, the T-shaped structure can reduce the lateral thrust of wind pressure on the sound-absorbing barrier, further improving the wind resistance of the sound-absorbing barrier. Optionally, the reflector in this embodiment can also be an arc-shaped extended reflector. The arc-shaped extended reflector scatters sound waves in multiple directions through curved surface reflection, reducing the propagation of mid- and low-frequency noise, while also reducing the local noise enhancement caused by concentrated sound energy reflection.

[0037] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
