Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sound barrier technology, specifically relating to a detachable multi-level through-hole ECP sound barrier. Background Technology
[0002] With the acceleration of urbanization, noise pollution from highways, railways, urban rail transit, and industrial plants has become a key issue affecting residents' quality of life and the ecological environment. Sound barriers, as core equipment for controlling noise propagation, are widely used along major traffic arteries and at industrial park boundaries due to their advantages such as convenient installation and direct sound insulation. In recent years, to address issues such as the susceptibility to corrosion of traditional metal sound barriers, the excessive weight of concrete sound barriers, and the insufficient strength of non-metallic sound barriers, cement-based composite materials (ECP) have gradually become one of the mainstream materials for sound barrier panels due to their lightweight, high strength, strong weather resistance, and excellent sound insulation performance.
[0003] However, existing ECP sound barriers still have many technical shortcomings in structural design and practical application, making it difficult to meet the requirements of efficient installation, convenient maintenance, and long-term stable use. The main problems are concentrated in the following aspects:
[0004] Firstly, assembly and maintenance flexibility is poor. Traditional ECP sound barriers mostly adopt an integral frame and fixed connection structure. The columns and sound barrier panels are often connected by welding or non-removable bolts, and the base and columns are often fixed by one-time casting. This design means that the sound barrier installation requires the use of large equipment for overall hoisting, resulting in a long construction period. If a single ECP sound barrier panel is damaged due to aging or impact, it is necessary to disassemble adjacent panels or even the entire frame to replace it. This not only results in high labor intensity and low maintenance efficiency, but also causes a lot of material waste and increases the later operation and maintenance costs.
[0005] Secondly, the connection between the column and the base lacks stability. In existing technologies, the connection between the column and the base is mostly fixed directly with bolts, lacking a pre-positioning structure. During installation, unevenness of the base surface or bolt positioning deviation can easily cause the column to tilt, affecting the verticality and stability of the overall sound insulation structure. At the same time, ordinary bolt connections have weak resistance to external forces and are prone to loosening under loads such as strong winds and vehicle vibrations, requiring frequent inspection and reinforcement, making it difficult to guarantee long-term safety.
[0006] Third, the protective design of the connection points is lacking. The core connection points of the ECP sound barrier are exposed to the outdoor environment for a long time, and rainwater and dust can easily seep into the gaps between the bolts and holes during the rainy season. The material difference between the metal bolts and the ECP panels can easily cause electrochemical corrosion, leading to bolt rust and jamming. This not only makes subsequent disassembly and reassembly difficult but also weakens the connection strength. Although some sound barriers have added simple cover plates, they are mostly snap-on designs that cannot completely seal the top and side gaps, resulting in limited protective effect and shortening the overall service life of the sound barrier.
[0007] In summary, existing ECP sound barriers have significant shortcomings in terms of assembly / disassembly flexibility, connection stability, environmental adaptability, and manufacturing processes, failing to simultaneously meet the practical needs of convenient assembly, reliable fixation, long-term protection, and low-cost maintenance. Therefore, developing an ECP sound barrier with a detachable modular structure, reinforced connection design, comprehensive protective functions, and optimized manufacturing process has become a key direction for addressing current technical pain points.
[0008] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0009] This invention provides a detachable multi-level through-hole ECP sound barrier, which aims to solve the technical problems mentioned in the background art.
[0010] To achieve the above objectives, the technical solution of this utility model is as follows:
[0011] A detachable, multi-stage perforated ECP sound barrier includes two spaced-apart columns, multiple ECP sound barrier panels, and a base. The multiple ECP sound barrier panels are vertically connected between the two columns.
[0012] The column includes a fixing part and an L-shaped mounting part. The fixing part is connected to the base, and the L-shaped mounting part is located at the upper end of the fixing part and is equipped with fastening bolts.
[0013] The ECP sound barrier panel has square holes on both the left and right sides. The ECP sound barrier panel passes through the square holes with fastening bolts and is connected to the L-shaped mounting part for limiting.
[0014] Preferably, the base has a recessed placement slot, and an anchor bolt is pre-installed in the placement slot. The fixing part is located in the placement slot and is connected to the base for limiting by the anchor bolt.
[0015] Preferably, the L-shaped mounting part 12 is provided with a sliding groove, and an L-shaped cover plate is provided in the sliding groove.

[0029] 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.
[0030] Example
[0031] like Figures 1 to 4 As shown, a detachable multi-stage through-hole ECP sound barrier includes two spaced-apart columns 1, multiple ECP sound barrier panels 2, and a base 3. The multiple ECP sound barrier panels 2 are vertically connected between the two columns 1. Each column 1 includes a fixing part 11 and an L-shaped mounting part 12. The fixing part 11 is connected to the base 3. The L-shaped mounting part 12 is located on the upper end of the fixing part 11 and is provided with fastening bolts 4. Square holes 21 are opened laterally on both the left and right sides of the ECP sound barrier panels 2. The ECP sound barrier panels 2 pass through the square holes 21 through the fastening bolts 4 and are limited and connected to the L-shaped mounting part 12.
[0032] The column 1, ECP sound barrier panel 2, and base 3 of this utility model are all detachably connected, eliminating the need for irreversible processes such as welding. This significantly reduces the difficulty of assembly and the labor intensity of later replacement and maintenance. When a single ECP sound barrier panel 2 is damaged, it can be replaced simply by removing the corresponding fastening bolts, without having to disassemble the entire frame. This greatly reduces labor intensity, maintenance time, and material waste.
[0033] In this example, the horizontally arranged square holes 21 on the ECP sound barrier panel 2 facilitate the adjustment of the position of the ECP sound barrier panel 2, and facilitate the subsequent fixing of the ECP sound barrier panel 2 to the L-shaped mounting part 12 by using the fastening bolts 4 to cooperate with the square holes 21.
[0034] In this embodiment, please refer to Figure 1 and Figure 3 The base 3 has a recessed placement slot 31, and an anchor bolt 5 is pre-installed in the placement slot 31. The fixing part 11 is located in the placement slot 31 and is connected to the base 3 by the anchor bolt 5. In this example, the reliability of the connection between the column 1 and the base 3 is further refined and the detachable structure of the two is described in detail. That is, the base 3 has a recessed placement slot 31, and the anchor bolt 5 is pre-installed in the placement slot 31. The fixing part of the column 1 is directly embedded in the placement slot 31 and then locked and fixed to the base 3 by the anchor bolt 5.
[0035] The placement slot 31 serves as a preliminary limiting function, that is, the placement slot 31 can laterally position the fixing part 11 to prevent the column 1 from shifting during installation and improve the assembly accuracy; while the locking method of the anchor bolt 5 has higher connection strength than ordinary bolts and can withstand the impact of external forces such as wind; at the same time, the anchor bolt 5 is detachable, which does not affect the disassembly and assembly flexibility of the overall structure.
[0036] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 4The L-shaped mounting part 12 has a groove 121, and an L-shaped cover plate 6 is provided in the groove 121; the upper end of the L-shaped mounting part 12 has an end cover 7; the L-shaped cover plate 6 and the end cover 7 of this utility model form a double protection area by combining the side and the top, completely sealing the connection gap between the column 1 and the ECP sound barrier plate 2, preventing the bolt corrosion and hole jamming caused by rainwater and dust seepage, facilitating the later disassembly and replacement of the ECP sound barrier plate, and improving work efficiency.
[0037] In addition, considering the impact of extremely severe wind and snow weather, bolts can be used to connect the L-shaped cover plate 6 and the end cover 7 to further stabilize and limit their position. Other conventional technical methods are not elaborated here.
[0038] In this embodiment, the fixing part 11 and the L-shaped mounting part 12 are integrally formed; the column 1 adopts the integral forming process of the fixing part 11 and the L-shaped mounting part 12, such as extrusion molding or casting, to eliminate welding process and reduce manufacturing time, improve the overall structural strength of the column 1, and reduce the safety risk caused by splicing breakage; four square holes 21 are provided, and the four square holes 21 are respectively located at the four corners of the ECP sound barrier plate 2; the square holes 21 at the four corners of the ECP sound barrier plate 2 make the plate body bear the force evenly, avoid warping deformation, and reduce rework costs caused by structural defects.
[0039] The working principle of this utility model:
[0040] This utility model provides a detachable multi-level through-hole ECP sound barrier. In specific use and installation, the base 3 is first positioned and fixed at the installation site. Anchor bolts 5 are pre-installed in the preset placement slots 31 of the base 3. The fixing part 11 of the column 1 is inserted into the placement slots 31 to achieve the horizontal pre-positioning of the column 1 and ensure verticality. Then, the anchor bolts 5 are tightened. Through the locking force between the anchor bolts 5 and the fixing part 11, the column 1 is firmly fixed to the base 3 to form a stable support frame.
[0041] Multiple ECP sound barrier panels 2 are installed sequentially from top to bottom between two columns 1, aligning the square holes 21 on the left and right sides of the sound barrier panels with the fastening bolts 4 on the L-shaped mounting parts 12 of the columns. The fastening bolts 4 are tightened, and after passing through the square holes 21, they form a limiting connection with the L-shaped mounting parts 12. The axial force of the fastening bolts 4 clamps and fixes the ECP sound barrier panels 2, and the multiple panels are vertically spliced to form a complete sound insulation surface.
[0042] An L-shaped cover plate 6 is inserted into the groove 121 of the L-shaped mounting part 12. The L-shaped cover plate 6 slides along the groove 121 until it completely covers the connection gap between the ECP sound barrier plate 2 and the column 1, preventing external rainwater and dust from entering. Finally, an end cap 7 is fastened to the upper end of the L-shaped mounting part 12 to seal the top opening of the L-shaped mounting part 12. Together with the L-shaped cover plate 6, it forms a closed protective area to prevent the core connecting components from corroding.
[0043] When a single ECP sound barrier panel 2 needs to be replaced, first remove the end cap 7 at the corresponding position, pull out the L-shaped cover plate 6 along the slide groove 121, and then unscrew the fastening bolt 4 corresponding to the panel to remove the damaged panel. After replacing the new panel, reverse the process to complete the bolt fixing, L-shaped cover plate 6 installation and end cap 7 fastening, achieving quick maintenance without affecting the stability of adjacent panels and the overall structure.
[0044] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
