Description

Technical Field

[0001] This utility model relates to the field of railway facility technology, and in particular to a steel structure for use in sound barriers, and also to a sound barrier. Background Technology

[0002] With the rapid development of urbanization and the continuous advancement of transportation infrastructure construction, highways, railways, and other transportation lines are becoming increasingly dense. At the same time, traffic noise pollution is becoming increasingly serious, negatively impacting the quality of life, work efficiency, and even health of nearby residents. Noise barriers, as an effective facility for reducing traffic noise, are widely used along main traffic arteries, around factories, and near schools and residential areas.

[0003] Early sound barriers had simple structures and single functions, often using wood or brick. However, wooden sound barriers have poor durability, are easily eroded by wind and rain, and have a short service life; brick sound barriers are heavy, have high requirements for the foundation, lack installation flexibility, and are difficult to construct in complex terrain conditions.

[0004] With the development of the steel industry, steel structures, due to their advantages of high strength, light weight, and convenient construction, have gradually become the main structural form of sound barriers. However, existing steel structures for sound barriers still have many problems. Some steel structures lack overall integrity and are prone to component loosening, structural deformation, or even collapse under the influence of natural disasters such as strong winds and earthquakes, failing to continuously and stably perform their noise reduction function. In addition, the installation of some steel structures for sound barriers is complex, consuming a lot of manpower and time, resulting in high construction costs. Utility Model Content

[0005] This utility model provides a steel structure and a sound barrier for use in sound barriers, which solves the defects of existing steel structures used in sound barriers, such as easy loosening of components, structural deformation, and even collapse. It achieves a steel structure for sound barriers with strong wind and earthquake resistance and prevents deformation of the steel frame due to uneven local stress.

While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. 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.

[0053] 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.

[0054] 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.
