Technology Field
[0001] The present disclosure relates to a sound barrier structure, and specifically to a sound barrier structure having a heat-sensitive resin. Background Technology
[0003] Sound barrier structures refer to structures installed around roads or railways to reduce noise pollution by minimizing the sound generated as vehicles pass by. To effectively achieve this objective, sound barrier structures are typically installed in a tunnel-like shape that encloses the road or railway. However, due to this design, conventional sound barrier structures have a structure that makes it difficult for people inside to escape in an emergency.
[0004] If a fire occurs inside a tunnel, a means is required to safely and quickly move people inside to the outside of the tunnel. Such a means must be designed to be easily accessible from various locations within the tunnel, but conventional soundproof wall structures have a problem in that they are made of special materials designed solely to reduce noise, requiring a separate path to be installed that leads to an emergency exit or emergency passage. The problem to be solved

[0009] According to one embodiment of the present disclosure, the heat-sensitive resin may correspond to PLA (Polylactide).
[0010] According to one embodiment of the present disclosure, the color of a first soundproof panel comprising a heat-sensitive resin may be different from the color of a second soundproof panel that does not comprise a heat-sensitive resin.
[0011] According to one embodiment of the present disclosure, a structural adhesive may be further included between the reinforcing frame and the first soundproof panel.
[0012] According to one embodiment of the present disclosure, the structural adhesive may correspond to a heat-sensitive polyurethane adhesive. Effects of the invention
[0014] According to various embodiments of the present disclosure, the first soundproof panel of the soundproof wall structure comprises a heat-sensitive resin whose material properties change according to temperature, and can provide a soundproofing effect under normal conditions while also serving as a means to connect to an evacuation route in the event of a fire.
[0015] According to various embodiments of the present disclosure, depending on the arrangement of the first soundproof panel and the second soundproof panel constituting the soundproof wall structure, it can be designed to allow easy access to the evacuation route at various locations in the tunnel.
[0016] According to various embodiments of the present disclosure, the color of a first soundproof panel containing a heat-sensitive resin is different from the color of a second soundproof panel not containing a heat-sensitive resin, so that in the event of a fire, people can easily and quickly discover the first soundproof panel connected to the evacuation route.

[0029] In the present disclosure, "thermally responsive" (or "temperature-responsive") may refer to a material in which changes in molecular motion, interactions, or energy transfer occur in response to changes in temperature, thereby changing macroscopic physical or chemical properties. For example, "thermally responsive resin" may refer to a resin whose properties change in response to changes in temperature, and which undergoes structural or state changes above a certain temperature.
[0030] In the present disclosure, "resin" may refer to a polymeric material in which one or more molecular chains are ionically or covalently bonded to each other to form a network structure.
[0031] In the present disclosure, "PLA or Polylactide" may refer to any material (including racemic mixtures) that is a biodegradable polymer produced using glucose or lactose extracted from corn or sugarcane, which are plant-based raw materials, in which one or more L-lactide or D-lactide monomer molecules condense with each other to form a polyester.
[0032] FIG. 1 is a representative drawing showing a soundproof wall structure (100) according to one embodiment of the present disclosure. The soundproof wall structure (100) may include a reinforcing frame (110), a first soundproof panel (120) supported by the reinforcing frame (110), and an evacuation route (130) connected to the first soundproof panel (120) to support emergency escape. The reinforcing frame (110) may form the skeleton of the soundproof wall structure (100) to withstand the load of the entire structure and provide stability. For example, the reinforcing frame (110) may be made of a material with high strength, such as wood, metal, or reinforced plastic.
[0033] In one embodiment, the first soundproof panel (120) may include a heat-sensitive resin and is a structure designed to block or absorb sound or vibration. When the temperature of the soundproof wall structure (100) rises abnormally during a fire, the strength of the heat-sensitive resin constituting the first soundproof panel (120) decreases, allowing it to be easily broken by people inside. This allows people to form a passage leading to an evacuation route (130) within the soundproof wall structure (100) during a fire.
[0034] For example, the heat-sensitive resin may correspond to Polylactide (PLA). The first soundproof panel (120) containing PLA can be manufactured in various sizes and shapes while having shock absorption and noise attenuation characteristics. Specifically, the first soundproof panel (120) containing PLA can have its width, length, and thickness modified as needed to fit the design of the reinforcing frame (110). In addition, although it is shown as a rectangular plate shape in FIG. 1, it is not limited thereto and can have various shapes such as an arch shape.
[0035] Additionally, the first soundproof panel (120) containing PLA may lose structural strength at about 60 degrees Celsius and gradually begin to melt and become ductile. People can break the first soundproof panel (120) that has become ductile inside the soundproof wall structure (100) and form a passage leading to an evacuation route (130) connected to the first soundproof panel (120). At this time, this passage may be supported by a heat-insensitive reinforcing frame (110).
[0036] Through this configuration, the first soundproof panel (120) of the soundproof wall structure (100) includes a heat-sensitive resin whose material properties change according to temperature, thereby providing a soundproofing effect in normal times and a means to connect to an evacuation route (130) in the event of a fire.
[0037] FIG. 2 is a drawing for comparing a first soundproof panel containing a heat-sensitive resin and a second soundproof panel not containing a heat-sensitive resin according to one embodiment of the present disclosure. As illustrated, a soundproof wall structure (100) may include a first soundproof panel (210) containing a heat-sensitive resin and a second soundproof panel (220) not containing a heat-sensitive resin. The second soundproof panel (220) not containing a heat-sensitive resin may include glass fiber, polyurethane foam, polymethyl methacrylate (PMMA), or a combination thereof, which are commonly used in panels designed for the purpose of blocking or absorbing sound. Specifically, the second soundproof panel (220) that does not contain a heat-sensitive resin supports the soundproof wall structure (100) together with the reinforcing frame (110) even in the event of a fire, whereas the first soundproof panel (210) that contains a heat-sensitive resin can provide a means to connect to the evacuation route (130) in the event of a fire.
[0038] Through this configuration, the escape route (130) can be designed to be easily accessible from various locations in the tunnel depending on the arrangement of the first soundproof panel and the second soundproof panel constituting the soundproof wall structure.
[0039] According to one embodiment of the present disclosure, the color of the first soundproof panel (210) containing a heat-sensitive resin may be different from the color of the second soundproof panel (220) not containing a heat-sensitive resin. For example, the color of the second soundproof panel (220) not containing a heat-sensitive resin may be gray, and the color of the first soundproof panel (210) containing a heat-sensitive resin may be orange. As another example, the color of the second soundproof panel (220) not containing a heat-sensitive resin may be transparent, and the color of the first soundproof panel (210) containing a heat-sensitive resin may be fluorescent or phosphorescent. Through such a configuration, in a dark situation during a fire, people can quickly visually distinguish the first soundproof panel (210) containing a heat-sensitive resin, break the first soundproof panel (210), and form a passage leading to the evacuation route (130) connected thereto.
[0040] In addition, in one embodiment, the reinforcing frame (110) may form a grid structure. Specifically, the reinforcing frame (110) may include a stud (112) installed vertically with respect to the floor surface where the soundproof wall structure (100) is located, a runner (114) installed horizontally, and a fixing device connecting the stud (112) and the runner (114). The intersection points where the stud (112) and the runner (114) meet are fixed perpendicularly to each other by the fixing device, and a plurality of these intersecting fixing points may form a grid structure in the soundproof wall structure (100).
[0041] Additionally, although not illustrated, in another embodiment, the reinforcing frame (110) may further include a reinforcing channel that supports the first soundproof panel (120) by being installed parallel to a spacer or runner (114) connecting a plurality of studs (112).
[0042] FIG. 3 is a drawing showing a soundproof wall structure (100) further comprising a structural adhesive (122) according to one embodiment of the present disclosure. As illustrated, the soundproof wall structure (100) may further include a structural adhesive (122) between a reinforcing frame (110) and a first soundproof panel (120). Under normal circumstances, the structural adhesive (122) contributes to improving the stability and soundproofing effect of the entire soundproof wall structure (100) by strengthening the bond between the reinforcing frame (110) and the first soundproof panel (120) and absorbing friction and shock to relieve stress applied to the entire soundproof wall structure (100).
[0043] However, in a high-temperature environment, especially in the event of a fire, the structural adhesive (122) may have weak adhesive properties so that the first soundproof panel (120) can be easily separated from the reinforcing frame (110). For example, the structural adhesive (122) may correspond to a heat-sensitive polyurethane adhesive. A heat-sensitive polyurethane adhesive may have the characteristic of having reduced adhesive properties when the temperature exceeds a certain level. Specifically, a highly flexible polyester polyol or polyether polyol may be added so that the glass transition temperature (Tg) of the polyurethane adhesive corresponds to approximately 60 degrees Celsius. Additionally, a thermoplastic may be introduced to lower the glass transition temperature of the polyurethane adhesive. For example, the thermoplastic may correspond to polyolefin (POE, Polyolefin Elastomer), ethylene vinyl acetate (EVA, Ethylene Vinyl Acetate), polyvinyl acetate (PVA, Polyvinyl Acetate), polyethylene oxide (PEO, Poly Ethylene oxide), polypropylene oxide (PPO, Poly Propylene oxide), or a combination thereof.
[0044] Although the present disclosure has been described in relation to some embodiments, various modifications and changes may be made without departing from the scope of the present disclosure as understood by a person skilled in the art to which the invention of the present disclosure pertains. Furthermore, such modifications and changes should be considered to fall within the scope of the claims appended to this specification.
[0045] The preferred embodiments of the present invention described above are disclosed for illustrative purposes only, and those skilled in the art with ordinary knowledge of the present invention will be able to make various modifications, changes, and additions within the spirit and scope of the present invention, and such modifications, changes, and additions should be considered to fall within the scope of the claims.
[0046] Since various substitutions, modifications, and changes are possible within the scope of the technical concept of the present invention without departing from the spirit of the invention, the present invention is not limited by the aforementioned embodiments and attached drawings.
