Description

Technical Field

[0001] This utility model relates to the field of sound barrier technology, and in particular to an insert-type sound barrier. Background Technology

[0002] With the acceleration of urbanization and the densification of transportation networks, noise pollution has become a significant environmental problem affecting the quality of life for residents. Sound barriers, as an effective noise control facility, are widely used in areas such as highways, railways, and urban overpasses. Insertable sound barriers, due to their modular design, convenient installation, and reusability, are gradually becoming one of the mainstream solutions.

[0003] However, existing panel-type sound barriers typically employ a single-column support structure, with the column fixed to the foundation frame by welding or bolting, and sound-absorbing or sound-insulating panels installed on both sides. Under long-term wind loads, vibration, and environmental corrosion, this type of structure is prone to problems such as column deformation and loosening of connection nodes, leading to a decline in sound insulation performance. Furthermore, existing column systems often use a uniform cross-section design, resulting in uneven stress distribution between the ends and the middle. In extreme weather or large-span scenarios, this may cause localized stress concentration, affecting overall stability. Some improvement schemes attempt to enhance structural strength by increasing the number of columns or their cross-sectional dimensions, but this leads to material waste, increased construction complexity, and difficulties in later maintenance. In addition, traditional sound barriers often rely on on-site welding or complex fasteners, resulting in low installation efficiency and high requirements for construction precision.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0028] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “” used herein may also indicate the inclusion of the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated, unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0029] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0030] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure.

Therefore, the example term "below" can include both upper and lower orientations. The device may also be rotated 90 degrees or in other orientations, and the spatial relative descriptors used in the text will be interpreted accordingly.

[0031] like Figures 1 to 9 As shown, according to an embodiment of the first aspect of this utility model, an insert-type sound barrier is proposed, including a frame, a column assembly and a folded channel steel 5, with a column assembly provided on each side of the frame; Each column group includes multiple columns 14; In each column group, multiple columns 14 are spaced apart from the first end to the second end of the frame. The second side of the column 14 at the first end is provided with a folded channel steel 5, the first side of the column 14 at the second end is provided with a folded channel steel 5, and both sides of each column 14 in the middle are provided with folded channel steel 5.

[0032] In the above embodiments, it should be noted that each column group is connected to a metal sound-absorbing plate between every two adjacent columns 14. One side of the metal sound-absorbing plate is inserted into one of the folded channel steel 5, and the other side of the metal sound-absorbing plate is inserted into another folded channel steel 5.

[0033] The first and second ends of the frame are the two opposite ends of the frame's longitudinal direction.

[0034] The first side and the second side of the column 14 are the opposite sides of the column 14.

[0035] The technical effects achieved by the above embodiments are as follows: Multiple columns 14 of the column assembly are spaced apart from both ends to the middle of the frame. Combined with the arrangement of the columns 14 on one side at both ends of the folded channel steel 5 and the columns 14 on both sides in the middle, a support system combining symmetry and asymmetry is formed. This design can effectively disperse wind loads, vibrations, and sound pressure impacts, avoid the stress concentration problem of traditional uniform cross-section columns 14, and improve fatigue resistance and extend service life through multi-node support.

[0036] The folded channel steel 5 serves as a standardized connector, replacing traditional welding or complex bolt structures and simplifying the assembly process of the column 14 and the frame. The single-sided channel steel design of the two end columns 14 facilitates the rapid positioning of the first and last units, while the double-sided channel steel of the middle column 14 ensures flexible splicing of the sound-absorbing panels, significantly shortening the construction cycle and reducing labor costs.

[0037] Optional, such as Figures 2 to 3 As shown, the frame includes a top crossbeam 1, a top longitudinal beam 10, and two lower longitudinal beams 4. The two lower longitudinal beams 4 are located on both sides of the top longitudinal beam 10.

Multiple top crossbeams 1 are connected between the first and second ends of the top longitudinal beam 10 at intervals. The upper ends of the two column groups are connected to multiple top crossbeams 1. The lower end of one column group is connected to one of the lower longitudinal beams 4, and the lower end of the other column group is connected to another lower longitudinal beam 4. In each column group, the upper end of each column 14 is connected to a top crossbeam 1, and the lower end of each column 14 is connected to the corresponding lower longitudinal beam 4.

[0038] In the above optional embodiments, it should be noted that the top longitudinal beam 10 is sequentially inserted on multiple top transverse beams 1, and the relationship between the top longitudinal beam 10 and each top transverse beam 1 is that the top longitudinal beam 10 is located in the middle of the top transverse beam 1. The cross-sectional shape of the structure formed by the two column groups, multiple top transverse beams 1, top longitudinal beam 10 and two lower longitudinal beams 4 is arched or rectangular; each column 14 is connected to the end of the corresponding top transverse beam 1.

[0039] Optional, such as Figures 1 to 3 As shown, the frame also includes a central longitudinal beam 7, and multiple columns 14 of each column group are connected to the central longitudinal beam 7. The central longitudinal beam 7 is located between the top longitudinal beam 10 and the lower longitudinal beam 4.

At least two lower cross beams 3 are connected between the two lower longitudinal beams 4 at intervals. The top cross beam 1, the top longitudinal beam 10, the lower longitudinal beams 4, the middle longitudinal beams 7 and the column 14 are all made of reinforced concrete.

[0041] The advantages of the above optional embodiments are: the combination of the top horizontal beam 1, the top longitudinal beam 10 and the two lower longitudinal beams 4 with the middle longitudinal beam 7 and the lower horizontal beam 3 ensures the robustness and reliability of the sound barrier structure.

[0046] In the above optional embodiments, it should be noted that in each column group, the specific structure of the two I-beams 9 between each pair of adjacent columns 14 is as follows: one I-beam 9 is connected between the top longitudinal beam 10 and the middle longitudinal beam 7, and the other I-beam 9 is connected between the middle longitudinal beam 7 and the lower longitudinal beam 4. At this time, the number of metal sound-absorbing plates between the two columns 14 is 4. A metal sound-absorbing plate is inserted on both sides of each I-beam 9, and the side of each metal sound-absorbing plate facing away from the corresponding I-beam 9 is inserted on the folded channel steel 5 on the side of the corresponding column 14.

[0047] The advantages of the above-mentioned optional embodiments are as follows: Two I-beams 9 are installed between each adjacent column 14 and rigidly connected to the frame to form a crisscrossing grid support system. The high moment of inertia of the I-beams 9 can significantly improve the lateral stiffness of the column group, effectively suppressing lateral deformation caused by wind pressure and vehicle vibration, and reducing the risk of deflection of the sound barrier panels. The I-beams 9 can be quickly fixed to the frame with bolts or clips, eliminating the need for on-site welding and reducing construction complexity.

[0048] Optional, such as Figures 1 to 4 , Figure 6 , Figure 8 and Figure 9 As shown, it also includes embedded parts 2, and each I-beam 9 is connected to the frame through embedded parts 2.

The embedded steel plate 202 is set in the frame, and the connecting plate 203 is connected to one side of the embedded steel plate 202. The connecting plate 203 is connected to the corresponding I-beam 9.

The embedded reinforcement bar 201, through the dual action of mechanical interlocking and chemical bonding, significantly improves the pull-out bearing capacity of the embedded part 2, making it particularly suitable for soft soil foundations or high wind pressure areas, effectively preventing the loosening and displacement of the folded channel steel 5 caused by long-term vibration or impact.

[0058] Optional, such as Figure 5 and Figure 7 As shown, it also includes pre-embedded anchor bolts 6, and each folded channel steel 5 is connected to the corresponding column 14 through the pre-embedded anchor bolts 6.
