Description

Smoke exhaust system for soundproof tunnels

[0001] The present invention relates to a smoke exhaust device for a soundproof tunnel, and more particularly, to a smoke exhaust device for a soundproof tunnel that can minimize casualties or prevent disasters caused by fire in a soundproof tunnel by quickly exhausting smoke or toxic gases generated inside a soundproof tunnel to the outside of the soundproof tunnel when a fire occurs.

[0002] In general, buildings located adjacent to roads experience various problems due to traffic noise caused by vehicles driving on the road.

[0003] Recently, noise barriers are being installed in the shape of walls to reduce traffic noise around roads, but noise barriers have the problem that it is difficult to increase the height, the noise reduction effect is low due to noise diffraction, and the construction cost is very high.

[0004] Recently, soundproof tunnels are being developed and distributed that have excellent soundproofing effects, no noise diffraction, excellent traffic noise reduction effects, are advantageous in securing views by reducing the height of soundproofing facilities, and are structurally safe.

[0005] The soundproof tunnels being developed recently are widely using a structure that combines transparent soundproof panels in a tile shape with a steel beam, and the materials used for the transparent soundproof panels are polymethyl methacrylate (PMMA), polycarbonate (PC), acrylic, etc.

[0006] However, PMMA, PC or acrylic have low flash points and are flammable, so if a fire breaks out in a soundproof tunnel, the fire can spread rapidly, generating a large amount of toxic smoke and causing structural collapse, resulting in casualties.

[0007] Recently, a technology has been developed to prevent the generation of toxic gases and the spread of flames due to combustion of transparent soundproofing panels for soundproofing tunnels by applying flame-retardant or non-combustible materials instead of flammable materials such as PMMA, PC, or acrylic.

[0008] However, when a fire occurs in a soundproof tunnel using a transparent soundproof panel that is flame-retardant or non-combustible, flames, toxic gases, and smoke are prevented from being discharged from the upper part of the soundproof tunnel, and thus flames, toxic gases, and smoke may move or convect from the roof of the soundproof tunnel toward the lower part of the soundproof tunnel, resulting in serious casualties due to flames, toxic gases, and smoke.

[0009] Recently, a technology has been developed to prevent the generation of toxic gases and the spread of flames due to combustion of transparent soundproofing panels for soundproofing tunnels by applying flame-retardant or non-combustible materials instead of flammable materials such as PMMA, PC, or acrylic.

[0010] However, when a fire occurs in a soundproof tunnel using a transparent soundproof panel that is flame-retardant or non-combustible, flames, toxic gases, and smoke are prevented from being discharged from the upper part of the soundproof tunnel, and thus flames, toxic gases, and smoke may move or convect from the roof of the soundproof tunnel toward the lower part of the soundproof tunnel, resulting in serious casualties due to flames, toxic gases, and smoke.

[0011] The present invention provides a smoke exhaust device for a soundproof tunnel, which can prevent flames and smoke from being emitted and filling the inside of the soundproof tunnel, thereby posing a threat to the safety of evacuees, when a transparent soundproof panel forming the soundproof tunnel is made of a flame-retardant or non-combustible material.

[0013] The operating unit of the smoke exhaust device for a soundproof tunnel includes a support member that is disposed on the other side of the smoke exhaust window opposite the hinge member and supports the smoke exhaust window, a solenoid unit that retracts the support member in response to a fire detection signal provided when a fire occurs and rotates the smoke exhaust window relative to the cover structure, and a fire detection sensor that generates the fire detection signal that operates the solenoid unit when a fire occurs.

[0014] The above operating unit of the smoke exhaust device for a soundproof tunnel includes a touch switch for generating the fire detection signal by touch when the fire detection sensor is damaged by fire and cannot generate the fire detection signal.

[0015] The above-described operating unit of the smoke exhaust device for a soundproof tunnel includes a support block disposed on the other side of the smoke exhaust window opposite the hinge member to support the smoke exhaust window, an elastic member coupled to the support block to retract the support block from the smoke exhaust window, a lifting block having a reverse slope that contacts the rear surface of the support block, and a moving unit disposed on the lower surface of the lifting block to raise and lower the support block so that the support block is separated from the smoke exhaust window and rotate the smoke exhaust window.

[0016] The above-described operating unit of the smoke exhaust device for a soundproof tunnel includes a flexible bag and an expansion gas provided to the bag to expand the volume of the bag due to a temperature rise caused by a fire and thereby operate the elevating block.

[0017] The above-described operating unit of the smoke exhaust device for a soundproof tunnel includes a support member disposed on the other side of the smoke exhaust window opposite the hinge member, and a low-melting-point support block formed to protrude from the support member to support the smoke exhaust window, and which is melted or deteriorated by heat in the event of a fire to rotate the smoke exhaust window away from the cover structure.

[0018] A smoke exhaust device for a soundproof tunnel further comprises: a side wall smoke exhaust window made of a flame-retardant material and arranged in a tile shape on the side wall structure; a side wall hinge member coupled to one side of the side wall smoke exhaust window and the side wall structure so that the side wall smoke exhaust window rotates with respect to the side wall structure; and a side wall operating unit having the same structure as the operating unit for rotating the side wall smoke exhaust window to allow outside air to flow in when fire and smoke occur within the soundproof tunnel.

[0019] The smoke exhaust device for a soundproof tunnel according to the present invention has the effect of preventing flames and smoke from being discharged and filling the inside of the soundproof tunnel, thereby posing a threat to the safety of evacuees, when the transparent soundproofing panel forming the soundproof tunnel is made of a flame-retardant or non-combustible material.

[0033] FIG. 1 is a cross-sectional view schematically illustrating a soundproof tunnel and a smoke exhaust device for a soundproof tunnel according to one embodiment of the present invention.

[0034] Referring to Fig. 1, a soundproof tunnel (10) is formed in the shape of a tunnel on a road on which vehicles travel to reduce traffic noise generated by vehicles.

[0035] A soundproof tunnel (10) includes a side wall structure (2) formed in the form of a wall erected facing each other on both sides of a road, and a cover structure (4) placed on top of the side wall structure (2).

[0036] In one embodiment of the present invention, the side wall structure (2) and the cover structure (4) may include I-shaped steel or H-shaped steel, and the side wall structure (2) and the cover structure (4) may be firmly assembled by rivets, screws, or welding.

[0037] Hereinafter, various embodiments of a smoke exhaust device (500) for a soundproof tunnel that is installed in a soundproof tunnel (10) and exhausts flames, toxic gases, and smoke generated inside the soundproof tunnel (10) due to a fire will be described.

[0038] Example 1

[0039] Fig. 2 is a cross-sectional view illustrating a smoke exhaust device for a soundproof tunnel according to a first embodiment of the present invention. Fig. 3 is a cross-sectional view illustrating the smoke exhaust window of Fig. 2 with the exhaust window open.

[0040] Referring to FIGS. 1 to 3, a smoke exhaust device (500) for a soundproof tunnel includes a smoke exhaust window (50), a hinge member (100), and an operating unit (200).

[0041] The smoke exhaust window (50) is made of a transparent, flame-retardant, and non-combustible material, so that even if a fire breaks out inside the soundproof tunnel (10), it does not burn rapidly.

[0042] In one embodiment of the present invention, at least one smoke exhaust window (50) may be placed on a part of a cover structure (4) of a soundproof tunnel (10), and depending on the size of the soundproof tunnel (10), a plurality of smoke exhaust windows (50) may be placed continuously or intermittently in the soundproof tunnel (10).

[0043] The smoke exhaust window (50) can be manufactured as a flat plate or a curved plate depending on the shape of the cover structure (4) of the soundproof tunnel (10).

[0044] For example, if the cover structure (4) of the soundproof tunnel (10) has a flat shape, the smoke exhaust window (50) can also be manufactured in a flat shape, and if the cover structure (4) of the soundproof tunnel (10) has a convex arch shape, the smoke exhaust window (50) can also be manufactured in a curved plate shape.

[0045] In order to enable the smoke exhaust window (50) to rotate with respect to the cover structure (4), one end of the smoke exhaust window (50) and the cover structure (4) facing the one end are hinged by a hinge member (100).

[0046] In one embodiment of the present invention, the hinge member (100) may include, for example, a hinge that rotates the smoke exhaust window (50) relative to the cover structure (4). In addition, the hinge member (100) may include a hinge protrusion protruding from both sides of the smoke exhaust window (50) and a hinge groove formed in the cover structure (4) into which the hinge protrusion is fitted.

[0047] The operating unit (200) causes the smoke exhaust window (50) to rotate about the hinge member (100) relative to the cover structure (4) in the event of a fire, thereby discharging flames, toxic gases, and smoke inside the soundproof tunnel (10) to the outside of the soundproof tunnel (10).

[0048] When the smoke exhaust window (50) is rotated with respect to the cover structure (4) by the operating unit (200) to form an open opening in the cover structure (4) of the soundproof tunnel (10), flames, toxic gases and smoke inside the soundproof tunnel (10) are discharged to the outside of the soundproof tunnel (10).

[0049] When a fire occurs and the smoke exhaust window (50) is opened by the operating unit (200) to form an opening in the cover structure (4), the maximum temperature inside the soundproof tunnel (10) is only about 158°C, which does not exceed the fire resistance limit temperature, so that the speed and distance of spread of flames, toxic gases, and smoke caused by the fire inside the soundproof tunnel (10) are greatly reduced, thereby allowing drivers inside the soundproof tunnel (10) to secure the time necessary for evacuation.

[0050] In one embodiment of the present invention, the operating unit (200) includes a support member (205), a solenoid unit (210), and a fire detection sensor (215).

[0051] The support member (205) is placed on the other side of the smoke exhaust window (50) facing the hinge member (100), and the smoke exhaust window (50) is supported by being placed on the support member (205). A part of the support member (205) is coupled to the solenoid unit (210).

[0052] The solenoid unit (210) uses electric energy to move the support member (205) away from the other side of the smoke exhaust window (50) so that the smoke exhaust window (50) rotates relative to the cover structure (4).

[0053] The fire detection sensor (215) is electrically connected to the solenoid unit (210), and the fire detection sensor (215) detects a fire when a fire occurs inside the soundproof tunnel (10) and generates a fire detection signal, and the fire detection signal is applied to the solenoid unit (210).

[0054] The solenoid unit (210) responds to a fire detection signal generated from a fire detection sensor (215) by retracting the support member (205), so that the smoke exhaust window (50) rotates relative to the cover structure (4) via the hinge member (100) as shown in FIG. 3.

[0055] Referring to FIG. 2, the operating unit (200) may further include a touch switch (220). When the fire detection sensor (215) is damaged by fire and a fire detection signal cannot be generated from the fire detection sensor (215), the touch switch (220) generates a fire detection signal by directly operating it by touch by a person inside the soundproof tunnel (10).

[0056] In response to the fire detection signal generated by the touch switch (220), the solenoid unit (210) retracts the support member (205), thereby causing the smoke exhaust window (50) to rotate relative to the cover structure (4) via the hinge member (100), as shown in FIG. 3.

[0057] Example 2

[0058] Fig. 4 is a cross-sectional view illustrating a smoke exhaust device for a soundproof tunnel according to a second embodiment of the present invention. Fig. 5 is a front view taken in the 'A' direction of Fig. 4. Fig. 6 is a cross-sectional view illustrating the smoke exhaust window of Fig. 4 in an open state. In the second embodiment of the present invention, the soundproof tunnel (10), the smoke exhaust window (50), and the hinge member (100) have substantially the same configuration as those of the first embodiment described above, so that redundant descriptions of the same configurations will be omitted, and the same names and reference numerals will be given to the same configurations.

[0059] Referring to FIGS. 4 to 6, a smoke exhaust device (500) for a soundproof tunnel includes a smoke exhaust window (50), a hinge member (100), and an operating unit (200).

[0060] The operating unit (200) includes a support block (225), an elastic member (230), an elevating block (235), and a movable unit (240).

[0061] The support block (225) is placed on the other side of the smoke exhaust window (50) facing the hinge member (100), and the smoke exhaust window (50) is supported by being placed on the support block (225).

[0062] The support block (225) includes a body (221), a protrusion (222), and an inclined portion (223).

[0063] The body (221) is formed in a block shape, and the protrusion (222) protrudes forward from the body (221) toward the exhaust window (50). The protrusion (222) supports the lower surface of the exhaust window (50).

[0064] The inclined portion (223) is formed on the rear side of the body (221) facing the protrusion (222), and the inclined portion (223) is formed to be inclined with respect to a direction perpendicular to the ground.

[0065] The elastic member (230) may include a tension spring that generates a tensile force.

[0066] One end of the elastic member (230) can be coupled to the cover structure (4), and the other end of the elastic member (230) can be coupled to the inclined portion (223) of the support block (225).

[0067] The elevation block (235) is formed in a block shape that moves in a direction perpendicular to the cover structure (4), and the elevation block (235) is elevated and lowered along a guide member (not shown) that is vertically connected to the cover structure (4).

[0068] The ascending and descending block (235) has a hollow (237) formed through the front facing the support block (225) and the rear facing the front.

[0069] The front surface facing the inclined portion (223) of the body (221) of the support block (225) among the ascending and descending blocks (235) is formed as a reverse slope (236) parallel to the inclined portion (223).

[0070] The elastic member (230) penetrates the hollow (237) of the lifting block (235).

[0071] Accordingly, when the lifting block (235) is raised, the support block (225) is retracted by the tensile force of the elastic member (230), and as a result, the exhaust window (50) supported on the support block (225) is separated from the support block (225) and rotates around the hinge member (100).

[0072] The movable unit (240) is attached to the support (238) formed at the bottom of the elevating block (235), and the movable unit (240) pushes the support (238) upward so that the elevating block (235) can move upward.

[0073] In one embodiment of the present invention, the movable unit (240) includes a flexible bag (242) and an expansion gas (not shown) disposed inside the bag (242) to expand the volume of the bag (242) due to an increase in the internal temperature of the soundproof tunnel (10) caused by fire, thereby moving the elevation block (235) upward. In one embodiment of the present invention, the expansion gas may be, for example, air.

[0074] Although in one embodiment of the present invention, the movable unit (240) is shown and described as being a bag (242) and an expanding gas that is provided to the bag and expanded by heat, the movable unit (240) may alternatively include a solenoid unit, various linear reciprocating motion units.

[0075] Example 3

[0076] Fig. 7 is a cross-sectional view illustrating a smoke exhaust device for a soundproof tunnel according to a third embodiment of the present invention. Fig. 8 is a cross-sectional view illustrating the smoke exhaust window of Fig. 7 with the window open. In the third embodiment of the present invention, the soundproof tunnel (10), the smoke exhaust window (50), and the hinge member (100) have substantially the same configuration as those of the first embodiment described above, so that redundant descriptions of the same configurations will be omitted, and the same names and reference numerals will be given to the same configurations.

[0077] Referring to FIGS. 7 and 8, a smoke exhaust device (500) for a soundproof tunnel includes a smoke exhaust window (50), a hinge member (100), and an operating unit (200).

[0078] In one embodiment of the present invention, the operating unit (200) includes a support member (252) disposed on the other side of the smoke exhaust window (50) opposite the hinge member (100).

[0079] In addition, it may include a low melting point support block (254) that is formed to protrude from the support member (252) and supports the smoke exhaust window (50), and is melted by heat in the event of a fire to rotate the smoke exhaust window (50) away from the cover structure (4).

[0080] In one embodiment of the present invention, the low melting point support block (254) may include, for example, a low melting point metal that melts at about 100° C. to 150° C. and has rigidity at room temperature.

[0081] According to a third embodiment of the present invention, when a fire occurs, even if the fire detection sensor or switch does not operate due to a loss of power supply, as shown in FIG. 7, the low melting point metal is melted by heat, and the smoke exhaust window (50) rotates from the cover structure (4) so ​​that the flames, toxic gases, and smoke inside the soundproof tunnel (10) can be discharged to the outside.

[0082] In the present invention, the first embodiment, the second embodiment, and the third embodiment are used separately, but in the second embodiment, the solenoid unit of the first embodiment can be applied to the elastic member, and the low-melting-point metal of the third embodiment can be applied to the protrusion (222) of the second embodiment.

[0083] When a fire occurs due to this, a fire sensing signal is first applied from a fire detection sensor to operate a solenoid unit to rotate the smoke exhaust window (50) away from the cover structure (4), and when the fire detection sensor is lost due to a fire, a touch switch is operated to provide a fire sensing signal to the solenoid unit to rotate the smoke exhaust window (50) away from the cover structure (4), and when the touch switch is also lost due to a fire, the smoke exhaust window (50) is rotated away from the cover structure (4) by melting of a low-melting-point metal, so that flames, toxic gases or smoke inside the soundproof tunnel (10) can be quickly discharged to the outside.

[0084] Meanwhile, high-temperature flames, high-temperature toxic gases and high-temperature smoke generated by the fire rise toward the cover structure (4), but even if the smoke exhaust window (50) from the cover structure (4) is opened, some of the flames, toxic gases and smoke descend downward along the side wall structure (2), which may result in loss of life.

[0085] To solve this problem, as shown in Fig. 1, the side wall structure (2) includes a side wall exhaust window (260), a side wall hinge member (270), and a side wall operating unit (280).

[0086] The side wall exhaust window (260) can open and close an opening formed in the side wall structure (2), and the side exhaust window (260) has substantially the same configuration as the exhaust window (50).

[0087] The side wall hinge member (270) is coupled to the side wall smoke exhaust window (260), and the side wall hinge member (270) has substantially the same configuration as the hinge member (100), and the side wall smoke exhaust window (360) is rotated inward or outward of the soundproof tunnel (10) by the side wall hinge member (270).

[0088] The side wall operating unit (280) has substantially the same configuration as the operating unit (200) described in the first to third embodiments, and allows the side wall smoke exhaust window (260) to rotate inward or outward of the soundproof tunnel (10).

[0089] In one embodiment of the present invention, when the smoke exhaust window (50) is opened due to a fire, the side wall actuator unit (280) may be operated according to the opening of the smoke exhaust window (50) to open the side wall smoke exhaust window (260).

[0090] As the side wall smoke exhaust window (260) is opened, air from the outside flows into the interior of the soundproof tunnel (10), and flames, toxic gases, and smoke are quickly discharged to the outside of the soundproof tunnel (10) through the smoke exhaust window (50), thereby minimizing damage to human life.

[0091] As described in detail above, the smoke exhaust device for a soundproof tunnel uses a flame-retardant or non-combustible material as the transparent soundproof panel forming the soundproof tunnel to prevent the spread of flames in the event of a fire, while quickly exhausting flames, toxic gases, and smoke inside the soundproof tunnel, thereby minimizing casualties.

[0092] Meanwhile, the embodiments disclosed in this drawing are merely specific examples presented to aid understanding and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical concepts of the present invention are possible in addition to the embodiments disclosed herein.

[0093] The present invention can be used in a soundproof tunnel to minimize casualties or prevent disasters caused by fire by quickly discharging smoke or toxic gases generated inside the soundproof tunnel to the outside of the soundproof tunnel when a fire occurs.
