Description

Technical Field

[0001] The utility model relates to the technical field of noise control, and particularly relates to a modular landscape sound barrier system with anti-loosening design. Background Technique

[0002] With the rapid advancement of urbanization construction in China, sound barriers have been widely applied and developed, and noise control technologies have been continuously improved, but there is still room for improvement.

[0003] The most common installation processes of acoustic components in the sound barrier industry are the plug-in type and the over-cladding type. The plug-in type adopts the traditional sound barrier installation process, that is, inserting sound barrier unit plates between adjacent H-shaped steel structures; the over-cladding type sound barrier is to lay various sound-absorbing and sound-insulating materials in layers on the outside of the main steel structure.

[0004] For traditional plug-in type sound barriers, the installation process generally adopts direct insertion from the top of the main steel structure or side insertion from the inside of the steel frame. The existing problems are as follows:

[0005] (1) If the overlap between the unit plate and the main steel structure is insufficient, there may be a risk of the unit plate falling off; it is necessary to occupy the road inside the line for construction, and cross-operation with other specialties, which affects the construction progress.

[0006] (2) Sound leakage may occur at the gap position of the unit plate, affecting the overall noise reduction performance of the sound barrier and causing environmental protection complaints from surrounding residents.

[0007] (3) Water leakage will occur at the gap position of the unit plate, and ice floes may appear in winter in the northern region, affecting the safe operation of the line.

[0008] (4) The traditional plug-in type sound barrier is discontinuous at the steel structure position, and the main steel structure is exposed, making it difficult to achieve a good landscape effect.

[0009] The over-cladding type sound barrier is integrally laid in layers on the outside of the main steel structure, which can simultaneously achieve a good landscape effect and solve problems such as rainwater leakage and ice floes. However, the over-cladding type sound barrier also has the following defects: ① The structure layer is relatively thick; ② The installation efficiency is low; ③ The cost is relatively high, which limits the popularization and application of the over-cladding type sound barrier. Content of the Utility Model

[0011] The utility model adopts the following technical solutions:

[0012] A modular landscape sound barrier system with an anti-loosening design comprises a sound barrier unit plate, which is connected to a main steel structure. The sound barrier unit plate comprises a sound absorbing material, a perforated panel, a decorative sound insulation aluminum back plate and a keel. The sound barrier unit plate performs a modular design on the above-mentioned structural layers and assembles them into an integral module; the sound absorbing material is arranged between the perforated panel and the decorative sound insulation aluminum back plate to form a Helmholtz resonance sound absorption cavity; each end of the sound absorbing material is coated with a keel, the perforated panel and the decorative sound insulation aluminum back plate are respectively fixedly connected to the keel, and the decorative sound insulation aluminum back plate extends along the length direction of the sound barrier unit plate to form an ear plate; the decorative sound insulation aluminum back plate forms a tongue-and-groove structure at both ends of the sound barrier unit plate in the width direction, the thickness of the ear plate is less than the overall thickness of the sound barrier unit plate, and the main steel structure is located on the inner side of the ear plates of two adjacent sound barrier unit plates, and is fixedly connected to the sound barrier unit plates through a connecting piece.

[0013] Furthermore, anti-loosening bolts are embedded near both ends of the sound barrier unit panel in the length direction, and the anti-loosening screw of the anti-loosening bolt is embedded on the keel. The anti-loosening bolt passes through the perforated panel and is bolted and fixed to the connecting piece through an anti-loosening nut.

[0014] Preferably, the connecting member is a connecting plate arranged on both sides of the main steel structure, and the anti-loosening screw is bolted and fixed to the connecting plate through an anti-loosening nut.

[0015] Preferably, the decorative sound-insulating aluminum back panel is designed in a combination of various shapes, colors, and patterns to form a multi-level landscape design to meet various needs.

[0016] Furthermore, shock-absorbing rubber pads are respectively installed between the outer side surface of the main steel structure and the inner side surface of the ear plate, between the connecting piece and the perforated panel, and between the tongue and groove of the two sound barrier unit panels.

[0017] Furthermore, the joints formed by butting the ear plates of the two sound barrier unit panels are filled with foam rods, and the foam rods are sealed with weather-resistant sealant.

[0020] Preferably, the sound-absorbing material is rock wool, glass wool, aluminum foam, polyester fiber or polyester foam. If it is a mineral fiber material, it is advisable to wrap it with non-woven fabric, alkali-free hydrophobic fiberglass cloth, etc. to prevent rainwater infiltration and failure. The decorative sound-insulating aluminum backboard is a single-piece aluminum panel for metal curtain walls.

[0021] The technical solution of the present utility model has the following advantages:

[0022] A. The present utility model proposes a brand-new sound barrier construction method. Ear plates are designed at both ends of the sound barrier unit board to form a special "T" shape structure, realizing the installation of the sound barrier unit board from the outside to the inside of the line, subverting the traditional installation method of the plug-in type sound barrier on the inner side of the structure, avoiding cross-operation construction inside the line, and significantly improving the construction safety. Especially in the renovation project of existing lines, the present utility model has incomparable advantages in terms of installation method and construction efficiency.

[0026] E. The sound barrier unit board in the present utility model includes a sound-absorbing material, a keel, a perforated panel, and a decorative sound-insulating aluminum backboard, forming a Helmholtz resonance sound-absorbing cavity. When sound waves enter the cavity, the sound waves can enter the sound-absorbing material along the pores, causing the vibration of air molecules in the cavity. Due to the viscous resistance of the air and the friction between the air molecules and the pore walls, the sound energy is converted into heat energy and dissipated. At the same time, the decorative sound-insulating aluminum backboard can effectively block the transmission of noise, isolate the noise in the Helmholtz resonance sound-absorbing cavity, and continuously change the propagation path of the noise, so that the noise is continuously consumed during the propagation process, thereby achieving the purpose of sound absorption and noise reduction.

[0027] F. The utility model makes full use of the landscape function of the decorative aluminum single panel, achieves the purpose of not exposing the main structure, can improve the continuity of the external landscape of the plug-in type sound barrier, and can meet the requirements of high-standard landscape design of the sound barrier.

[0046] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0047] As Figures 1 - 5 shown, the present utility model provides a modular landscape sound barrier system with an anti-loosening design, which includes a sound barrier unit board 1. The sound barrier unit board 1 is connected to the main body steel structure 2 through a connecting piece 3; the sound barrier unit board 1 is lapped on the outside of the main body steel structure 2 through an ear plate 131; the gap between the sound barrier unit boards 1 is blocked by a foam rod 4 and a weather-resistant sealant 5; the upper and lower sound barrier unit boards 1 are connected through a rabbet structure 132.

[0048] The sound barrier unit board 1 includes a sound-absorbing material 11, a perforated panel 12, a decorative sound-insulating aluminum back plate 13, a keel 14, an anti-loosening bolt 15, and a shock-absorbing rubber pad 16. The sound-absorbing material 11 is arranged between the perforated panel 12 and the decorative sound-insulating aluminum back plate 13 to form a Helmholtz resonance sound-absorbing cavity for isolating and consuming noise energy; the decorative sound-insulating aluminum back plate 13 extends along the length direction of the sound barrier unit board 1 to form an ear plate 131, as Figure 3 and Figure 5As shown; the decorative sound insulation aluminum back plate 13 forms a tongue-and-groove structure 132 along both ends of the width direction of the sound barrier unit plate 1, as Figure 4 As shown. Among them, the thickness of the ear plate 131 is less than the overall thickness of the sound barrier unit plate 1, so that the decorative sound insulation aluminum back plate forms a "T"-shaped structure. The special "T"-shaped structure realizes the installation of the sound barrier unit plate from the outside of the line to the inside, subverting the traditional practice of installing the plug-in type sound barrier on the inside of the structure, avoiding cross-operation construction inside the line, and significantly improving the safety of construction. Especially in the existing line reconstruction project, the utility model has incomparable advantages in terms of installation method and construction efficiency.

[0049] The main steel structure 2 is located on the inner side of the ear plate 131 of two adjacent sound barrier unit panels 1, and is fixedly connected to the sound barrier unit panels 1 through the connector 3. Of course, each end of the sound-absorbing material 11 is coated with a keel 14, and the keel is preferably a galvanized steel keel. Reliable anti-corrosion measures should be taken at the welding points between the galvanized steel keels and between the embedded bolts to meet the durability requirements of the sound barrier. The perforated panel 12 and the decorative sound insulation aluminum back panel 13 are preferably connected to the keel 14 with rivets, respectively, and the riveting should ensure that the sound barrier is safe and reliable during use. The utility model embeds anti-loosening bolts 15 on the inner side of the sound barrier unit panel 1 near the end position. Of course, the connector 3 can also be directly connected to the main steel structure 2, and then the connector 3 is connected to the anti-loosening bolt 15, so that on-site construction is easier.

[0050] The utility model preferably has anti-loosening bolts 15 embedded at both ends of the length direction near the sound barrier unit plate 1. The anti-loosening bolts 15 penetrate the perforated panel 12 and are welded and fixed to the keel 14. The connector 3 is a connecting plate arranged on both sides of the main steel structure 2. The anti-loosening bolts 15 are fixedly connected to the connector 3. At the same time, the sound barrier unit plate 1 is tightly overlapped with the main steel structure 2. The ear plates 131 of the two adjacent sound barrier unit plates 1 are preferably elastically connected to the flange of the main steel structure 2 by EPDM shock-absorbing rubber pads 16. The vertical gap formed by the ear plates 131 of the two adjacent sound barrier unit plates on the left and right are filled with foam rods 4, and weather-resistant sealant (or EPDM rubber strips) 5 are used for sealing. The EPDM shock-absorbing rubber pad 16 is a component for buffering and vibration reduction, and is fixed at the connection between the sound barrier unit plate 1 and the main steel structure 2 or the connector 3 to avoid hard connection of the sound barrier unit plate 1 and the generation of secondary noise.

[0051] The connector 3 used is preferably an angle steel, one side of which is welded or bolted to the side of the main steel structure 2, and the other side is connected to the anti-loosening bolt 15. The perforated panel 12 is a galvanized steel plate or a rust-proof aluminum alloy plate with pinholes, round holes or louver holes. The sound-absorbing material 11 is a variety of porous materials such as rock wool, glass wool, foam aluminum, polyester fiber or polyester foam. The decorative sound insulation aluminum backboard 13 is a metal curtain wall aluminum single plate, and its thickness is generally 3mm, which replaces the traditional galvanized steel plate or aluminum alloy backboard (thickness generally does not exceed 1.5mm). The decorative sound insulation aluminum backboard 13 serves as the backboard of the sound barrier unit plate, which improves the landscape performance of the sound barrier unit and can meet the landscape design requirements at different levels through different forms of shape, color and pattern.

[0052] In the sound absorbing material 11, the connector 3 and the main steel structure 2 are the main force transmission components of the utility model, and their strength should meet the requirements of structural force. The form of the main steel structure 2 is determined by the structural design according to the needs, and the cross-section form can be H-shaped steel, square tube, round tube, etc.; the main structure form can be cantilever, door-shaped, circular, elliptical and other forms; the closed form of the sound barrier system can be upright, semi-enclosed or fully enclosed, and can be designed in combination with the requirements of the environmental impact assessment report or the actual needs of the project.

[0053] In addition, in order to enhance the landscape effect of the sound barrier of the utility model, a decorative design is adopted. A foam rod 4 and a weather-resistant sealant 5 are arranged in the vertical seam formed after the two ear plates are connected. This can improve the waterproof ability of the unit plate of the sound barrier of the utility model. Whether to adopt it can be decided according to the actual situation of the project.

[0054] The anti-loosening design modular landscape sound barrier provided by the utility model has the following installation method:

[0055] (1) Steel structure installation

[0056] Clean the top surface of the foundation and the embedded anchor bolts; strictly follow the operating specifications, select appropriate lifting equipment, and cooperate with the lifting and ground personnel to lift the columns and put them in place on the cleaned foundation surface; adjust the horizontal position and verticality of the columns, and tighten the anchor nuts; if there is a secondary leveling layer at the column base, pour leveling mortar to ensure the reliability of the column base node connection.

[0057] If it is a fully enclosed sound barrier, the steel beams and corresponding secondary structures should be hoisted to ensure the reliability of the structural connection during the installation and use process.

[0058] (2) Installation of sound barrier module

[0059] Push the lowermost sound barrier module horizontally from the outside of the main steel structure to the designated position to ensure reliable lapping between the lug plates of the sound barrier module and the main steel structure; ensure that the shock-absorbing rubber pads are closely pressed and firmly fixed at the connections between the plates and the foundation, between the plates, and between the plates and the outer flange of the main steel structure. Firmly bolt one side of the L-shaped connector to the embedded anti-loosening bolt of the sound barrier unit plate, and reliably connect the other side to the main steel structure. Install the upper sound barrier unit plates sequentially from bottom to top according to the specific grid determined by the landscape design, and adjust the verticality, parallelism, and longitudinal and transverse plate joint gaps of the sound barrier unit plates to ensure close pressing between the plates and between the plates and the columns.

[0060] (3) Caulking and sealing (if any)

[0061] Clean the longitudinal and transverse joints of the sound barrier unit plates to remove debris and dust. Paste masking paper on the surfaces of the sound barrier unit plates on both sides of the joints, embed the matching foam rod at the butt joints of the lug plates, and finally carry out caulking and sealing work. When caulking, it is required that the sealant joints are horizontal and vertical, of the same width, and evenly applied to ensure the beauty and reliability of the sealant joints; after caulking is completed, tear off the masking paper and clean the surface debris. As Figure 6 and Figure 7 shown in the two illustrations of the landscape sound barrier effects.
