Description

Technical Field

[0001] The invention relates to the technical field of wall structure design, in particular to a fireproof and soundproof decorative wall design structure for building energy saving. Background Art

[0002] Decorative walls, as the name suggests, are a practice of decorating walls. This treatment aims to enhance the aesthetics and practicality of the walls or to meet specific space separation needs. It combines multiple elements such as materials, shapes, functions, lighting and art to create a wall space that is both beautiful and practical. With the advancement of technology and changes in aesthetic concepts, wall decoration materials and methods have become more and more diversified, from simple paint to complex artistic tiles, marble curtain walls, etc. Wall decoration has gradually become an important way to show personality and taste.

[0003] When decorative walls are used as interior partitions in exhibition halls and other places, in order to ensure the safety and comfort in the exhibition hall, the fire prevention and sound insulation performance of the decorative walls is particularly important. However, most of the existing decorative wall designs, in pursuit of visual beauty, perform poorly in fire prevention and sound insulation performance, or even lack thereof. When the decorative walls lack sufficient fire prevention and sound insulation performance, not only will the poor sound insulation effect affect the visitor experience in the exhibition hall, but also in the event of an emergency such as a fire, the insufficient fire prevention performance of the decorative walls will cause the materials thereon to burn rapidly, thereby aggravating the spread of the fire, and further greatly aggravating the degree of fire hazards, posing an extremely serious threat to the safety of life and property of the visitors, and having poor practicality.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] 1. The present invention cooperates with the fireproof and sound-insulating mechanism and the auxiliary mechanism, and utilizes a multi-layer structure such as a metal perforated plate, sound-absorbing cotton, a steel keel frame and a rock wool interlayer thereon, an air layer between two sets of steel keels, a damping rubber pad, and an expanded perlite plate to form multiple isolation and absorption of noise, effectively reduce the propagation of noise, and thus effectively improve the sound insulation performance of the wall. In addition, by utilizing the liquid airbag filled with hydrogel inside and the setting of the inclined hollow groove on the sound-absorbing cotton (the hydrogel in the liquid airbag is not filled), not only can the sound insulation performance of the wall be further improved, but also when a fire occurs, the liquid airbag can be ruptured to release the hydrogel liquid inside onto the sound-absorbing cotton and form a hydrogel liquid layer to prevent it from burning directly, thereby ensuring the fireproof effect of the wall. In addition, if the fire intensity is large and the flame breaks through the hydrogel liquid layer, the setting of the intumescent fire-retardant coating can form a layer of fireproof and heat-insulating layer to effectively prevent the further spread of the fire, thereby further ensuring the fireproof performance of the wall.

[0021] 2. The present invention not only maintains the temperature of the exhibition hall stable through the heat preservation and heat insulation effect by setting the air layer between the two groups of steel keel frames in the fireproof and soundproof mechanism, but also effectively reduces the decibel value of the noise when the noise tries to penetrate the wall, making the exhibition hall more quiet and comfortable. In addition, the horizontal and vertical non-equidistant arrangement of the steel keel frames and the non-corresponding installation between the two groups of keel frames change the facing state of the gap. This design effectively interrupts the direct propagation path of the sound in the gap, making it difficult for the sound to be directly transmitted from one group of steel keel frames to another group of steel keel frames through the gap during the propagation process (the gap refers to the gap between the steel keel frame and the rock wool interlayer), but needs to be reflected, refracted and scattered multiple times by the rock wool interlayer on the steel keel frame, thereby effectively improving the sound insulation performance of the wall.

[0022] 3. The present invention can not only further improve the sound insulation performance of the wall through the arrangement of the expanded perlite plate, the damping rubber pad and the inclined hollow groove inside the sound-absorbing cotton in the metal perforated plate and the fireproof and soundproof mechanism, but also effectively ensure the fireproof performance of the wall by using the intumescent fire-retardant coating sprayed on the surface of the expanded perlite plate. When a fire occurs and the sound-absorbing cotton burns (that is, when the fire intensity is large), the intumescent fire-retardant coating can respond quickly to form a fireproof and heat-insulating layer, effectively blocking heat transfer and slowing down the spread of the fire. In addition, with the arrangement of the hydrogel in the liquid airbag in the auxiliary mechanism, a layer of hydrogel liquid layer can be provided for the sound-absorbing cotton before combustion (that is, at the initial stage of the fire or when the fire intensity is not large) to prevent it from directly burning, thereby improving the safety of the wall when in use. In addition, by using the hole arrangement on the surface of the metal perforated plate, while satisfying the decorative function of the wall surface, it also avoids the destructive operations such as punching and gluing the wall in the traditional decorative method, which not only protects the integrity of the wall, but also makes the change of the wall layout more convenient and flexible.

[0023] 4. The present invention, through the arrangement of the liquid airbag in the auxiliary mechanism, can utilize its "∞"-shaped structure and the arrangement of two groups of through grooves symmetrically penetrating one side thereof to form a multi-layer medium structure in which liquid and gas are distributed alternately. This multi-layer medium structure helps to isolate noise, thereby improving the sound insulation performance of the wall. The hydrogel filled in the liquid airbag is a viscoelastic material. Through its mutual friction and damping effect inside the liquid airbag, it can effectively consume sound energy and further reduce the transmission intensity of noise. In addition, since the hydrogel does not fill the liquid airbag and can flow, it can dynamically adjust its own distribution according to the incident direction and intensity of the sound wave, and can effectively suppress the resonance phenomenon, greatly reduce the transmittance of sound, thereby further improving the sound insulation performance of the wall.

[0024] 5. The present invention can achieve the sliding of the entire wall structure indoors (referring to the exhibition hall) through the cooperation of the card-jointed sliding mechanism and the auxiliary mechanism. After sliding to the specified position, the two sets of mounting blocks can slide obliquely upward to make the rubber pads at the top of the walls in close contact with the indoor roof, thereby improving the stability of the wall after movement. The upward oblique sliding of the two sets of mounting blocks in conjunction with the setting of the liquid airbag (that is, the two sides of the liquid airbag are squeezed by the two sets of mounting blocks) can make the liquid airbag extend in the vertical direction, and the air layer above the liquid airbag can produce multi-form compression deformation to adapt to the different shapes of the indoor ceiling, thereby further improving the stability of the wall after movement.

[0025] 6. The present invention, through the setting of the lighting monitoring mechanism, can utilize the setting of the spotlight on the opening and closing block to accurately illuminate the decorations or exhibits on the surface of the decorative wall, strengthen the key points, so as to better display the details of the objects, improve the display effect and viewing quality of the exhibition, and can utilize the smoke sensor and the temperature sensor to monitor the smoke concentration and temperature changes in the area near the wall. Once the smoke concentration exceeds the preset safety threshold and the temperature nearby rises rapidly (i.e., an emergency such as a fire may occur), the smoke sensor and the temperature sensor will promptly issue an alarm and locate the relevant position, thereby effectively ensuring the safety of the exhibition hall during the exhibition.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

The card-jointed sliding mechanism includes two groups of slide grooves and two groups of hydraulic parts 1. The two groups of slide grooves are respectively opened on the indoor top surface and the indoor bottom surface. A sliding protrusion is installed at the bottom end of the sliding base 7, and the sliding base 7 is card-joined in the slide groove on the indoor bottom surface through the sliding protrusion. The two groups of hydraulic parts 1 are respectively installed on the top of the hollow layer 5 and the wall back plate 15, and the output ends of the two groups of hydraulic parts 1 are both installed with slide rails. The hydraulic part 1 is the existing technology, and its specific structural design is no longer repeated here. The slide rails are all located above the hydraulic part 1, and the hollow layer 5 and the wall back plate 15 are both card-joined in the slide groove on the indoor top surface through the slide rails.

[0036] Reference Figures 1 to 4 A fireproof and soundproofing mechanism is provided between the two groups of metal perforated plates 8 to realize fireproofing and soundproofing of the entire wall structure. The fireproof and soundproofing mechanism includes two groups of sound-absorbing cotton 9 and two groups of steel keel frames 13. The two groups of sound-absorbing cotton 9 are respectively fixedly connected to the opposite sides of the two groups of metal perforated plates 8, and the tops of the two groups of sound-absorbing cotton 9 are provided with inclined hollow grooves 901. The two groups of sound-absorbing cotton 9 are provided with multiple groups of openings. The number and density of the holes on the two groups of metal perforated plates 8 are less than the number and density of the openings on the two groups of sound-absorbing cotton 9, and the positions of the holes on the two groups of metal perforated plates 8 correspond to the positions of some openings on the two groups of sound-absorbing cotton 9. The two groups of steel keel frames 13 are fixedly connected to the hollow layer 5, the wall back plate 15, the sliding base 7 and the fixing seat 20, and the two groups of steel keel frames 13 are located between the two groups of sound-absorbing cotton 9. An air layer is arranged between the two groups of steel keel frames 13, and rock wool interlayers 14 are installed in the spaces on the two groups of steel keel frames 13. The two groups of steel keel frames 13 have the same structure, and the horizontal and vertical frames of the two groups of steel keel frames 13 are arranged at non-equidistant distances near a group of corners, one group of steel keel frames 13 is completely corresponding to the other group of steel keel frames 13 rotated 180 degrees, damping rubber pads 12 are installed on the outward side of the two groups of steel keel frames 13, and the two groups of steel keel frames 13 are respectively fixedly connected with two groups of expanded perlite plates 11 through the damping rubber pads 12, the outward side of the two groups of expanded perlite plates 11 are sprayed with expandable fire retardant coating 10, and the two sides of the two groups of expanded perlite plates 11 sprayed with expandable fire retardant coating 10 are respectively fixedly connected with two groups of sound-absorbing cotton 9.

[0037] There is an air layer between the two groups of steel keel frames 13 on the inner side of the wall design structure. The horizontal and vertical frames of the steel keel frames 13 are arranged at non-equidistant distances. One of the steel keel frames 13 is rotated 180 degrees to completely correspond to the other steel keel frame 13. The spaces of different areas between the horizontal and vertical frames are installed with rock wool interlayers 14, and a layer of damping rubber pads 12 are attached to the sides and then clamped with expanded perlite plates 11. This has the following advantages.

[0038] First, the air layer between the two sets of steel keel frames 13 can play a role in heat preservation and insulation, preventing the rapid transfer of heat, thereby helping to maintain the stability of the temperature in the exhibition hall, providing a more comfortable and stable indoor environment for the audience in the exhibition hall, and when the noise tries to penetrate the wall, it will encounter the air layer, resulting in reflection, refraction and attenuation effects, thereby effectively reducing the decibel value of the noise, making the exhibition hall more quiet and comfortable.

[0039] Second: Since the steel keel frame 13 and the rock wool interlayer 14 cannot be installed in a completely tight fit, sound will be transmitted through the gap. Therefore, the non-equidistant arrangement of the horizontal and vertical frames of the steel keel frame 13 and the non-corresponding installation of the two groups of steel keel frames 13 can change the facing state of the gap between the two groups of steel keel frames 13. This design effectively interrupts the direct propagation path of the sound in the gap, making it difficult for the sound to be directly transmitted from one group of steel keel frames 13 to another group of steel keel frames 13 through the gap during the propagation process. When the sound is transmitted from the gap on one group of steel keel frames 13 (the gap refers to the gap between the rock wool interlayer 14 installed on the steel keel frame 13 and the steel keel frame 13), it will collide with the surface of the rock wool interlayer 14 on the other group of steel keel frames 13, and be reflected and refracted, thereby effectively reducing the size of the sound, thereby effectively improving the sound insulation performance of the wall.

[0040] Third: In addition to being a Class A non-combustible material, the expanded perlite board 11 has an internal porous structure that can reflect sound and has a significant absorption effect on high-frequency noise, thereby effectively reducing indoor reverberation and reflected sound, thereby further improving the sound insulation performance of the wall.

[0041] Fourth: a damping rubber pad 12 is used as a sandwich between the expanded perlite board 11 and the steel keel frame 13, and a layer of flexible material is inserted between the two layers of rigid materials. When sound waves cause vibrations, the damping rubber pad 12 can absorb vibration energy through its own elastic deformation, reduce structural resonance, and effectively block the propagation of medium and low frequency noise such as human voices, thereby effectively improving the sound insulation performance of the wall. In addition, the damping rubber pad 12 not only has the functions of sound insulation and shock absorption, but also can make the fit between the expanded perlite board 11 and the steel keel frame 13 tighter, thereby further improving the sound insulation performance of the wall.

[0042] A layer of expandable fire retardant coating 10 is sprayed on the surface of the expanded perlite board 11, and one side of the expanded perlite board 11 sprayed with the expandable fire retardant coating 10 is fixedly connected to the sound-absorbing cotton 9 (i.e., the expandable fire retardant coating 10 is in close contact with the sound-absorbing cotton 9 having inclined hollow grooves 901 therein), and the outermost metal perforated plate 8 has holes that are fewer in number and smaller in density than the sound-absorbing cotton 9, but completely correspond to the partial openings on the sound-absorbing cotton 9. This has the following advantages.

[0043] First: When a fire occurs, the physical properties of the sound-absorbing cotton 9 make it relatively flammable. If the sound-absorbing cotton 9 burns, the expandable fire-retardant coating 10 will be heated and rapidly expand to form a porous carbon foam layer. The porous carbon foam layer will fill the gap between the burned sound-absorbing cotton 9 and the metal perforated plate 8, thereby effectively blocking the transfer of heat and preventing the spread of fire, thereby effectively ensuring the fire resistance of the wall.

[0044] Second: the inclined hollow groove 901 inside the sound-absorbing cotton 9 can provide a variety of reflection and absorption paths for sound waves incident at different angles, avoiding excessive concentration or reflection of sound in a specific direction, thereby reducing echo and sound focusing, and improving the sound absorption and sound insulation performance of the wall. The inclined hollow groove 901 can effectively reflect high-frequency sounds with shorter wavelengths, causing them to interfere and superimpose each other. This process helps to quickly dissipate sound energy. At the same time, the inclined hollow groove 901 can also excite the sound-absorbing cotton 9 to vibrate in a larger range. This vibration is particularly conducive to consuming the energy of low-frequency sound waves, thereby effectively enhancing the sound absorption effect of the sound-absorbing cotton 9. In addition, the inclined hollow groove 901 also cleverly increases the air circulation channel inside the sound-absorbing cotton 9, so that the sound-absorbing cotton 9 can interact with sound waves more effectively, thereby effectively improving the sound absorption efficiency of the sound-absorbing cotton 9.

[0045] Third: The regular arrangement of holes on the surface of the metal perforated plate 8 can increase the layering and artistic sense of the wall, meet the aesthetic needs of decorating the wall, and the holes on the surface of the metal perforated plate 8 can also be inserted with hooks, brackets and other devices, thereby meeting the decorative function of the wall surface. At the same time, this design avoids the need for destructive operations such as punching and gluing on the wall in traditional decoration methods, which not only protects the integrity of the wall, but also makes the change of the wall layout more convenient and flexible. Since the position of the holes on the metal perforated plate 8 corresponds to the position of some openings on the sound-absorbing cotton 9, a continuous sound-absorbing channel can be formed. When sound waves contact the metal perforated plate 8, they will be guided into the interior of the sound-absorbing cotton 9 and undergo multiple reflections and absorption inside the sound-absorbing cotton 9, thereby maximizing the consumption of sound energy. This design not only maintains the original sound-absorbing effect of the sound-absorbing cotton 9, but also further improves the sound-absorbing effect of the sound-absorbing cotton 9 through the guiding effect of the metal perforated plate 8.

[0046] Reference Figure 1 as well as Figures 5 to 7 , auxiliary mechanisms are arranged on the fixing seat 20 and the hollow layer 5, which are used to improve the fireproof and soundproof performance of the entire wall structure.

The third gear 22, another set of rotating rods 21 are located in the multiple sets of second mounting grooves, and the outer wall of the rotating rods 21 in the multiple sets of second mounting grooves is symmetrically installed with another two sets of third gears 22. The bottom ends of the multiple sets of mounting blocks located at the top of the fixed seat 20 are provided with two sets of notches, and the two sets of notches are installed with gear rails. The two sets of rotating rods 21 are respectively meshed with the gear rails on the multiple sets of mounting blocks through the multiple sets of third gears 22. The hollow layer 5 and one end of the two sets of rotating rods 21 are jointly provided with a meshing portion near the edge for matching the gear rails. The bar 17 enables the two groups of rotating rods 21 to rotate outward or inward, and the meshing portion includes two groups of second gears 19, which are respectively installed at one end of the two groups of rotating rods 21 near the edge, and the two groups of second gears 19 are both located inside the hollow layer 5, and two groups of first gears 18 are rotatably connected inside the hollow layer 5, and the rack 17 is located between the two groups of first gears 18 and the two groups of second gears 19, and the two groups of first gears 18 are meshed with the rack 17, and the two groups of first gears 18 are meshed with the two groups of second gears 19.

[0048] Reference Figure 1 , Figure 5 and Figure 6 The two groups of mounting blocks on the sliding block 2 are both provided with a lighting monitoring mechanism on the outward side, which is used to light the outer surface of the two groups of metal perforated plates 8 and detect the smoke concentration and temperature changes in the nearby area. The lighting monitoring mechanism includes a through groove, which is opened through the bottom edge of the outward side of the mounting block, and an opening and closing block 3 is rotatably connected on the top wall of the through groove. A smoke sensor 301, a spotlight 302 and a temperature sensor 303 are installed at the bottom end of the opening and closing block 3, and the spotlight 302 is located between the smoke sensor 301 and the temperature sensor 303.

[0049] By pushing the entire wall design structure, and with the cooperation of the sliding protrusions on the sliding base 7 at the bottom end thereof and the slide rails on the two groups of hydraulic parts 1 at the top of the wall structure and the slide grooves in the room, the entire wall design structure can be slid. When the wall is pushed to the specified position, the square door 6 on the hollow layer 5 is opened, and the rotating handle 16 in the square groove is turned to rotate the driving gear. The driving gear rotates to cause the rack 17 to start moving up (the two groups of mounting blocks are not in a mutually fitting state before the rack 17 moves down). The upward movement of the rack 17 drives the two groups of first gears 18 to rotate outward, and the outward rotation of the two groups of first gears 18 drives the two groups of second gears 19 to rotate inward, so that the two groups of mounting blocks slide obliquely upward until they fit each other. A rotatable opening and closing block 3 is arranged below the sliding block 2 (referring to the two groups of mounting blocks), and a smoke sensor 301, a spotlight 302 and a temperature sensor 303 are installed on the opening and closing block 3. This has the following advantages.

[0050] First: The two sets of mounting blocks slide upward diagonally so that the rubber pads on the top can be in close contact with the indoor roof, improving the stability of the wall after movement.

[0051] Second: the spotlight 302 on the opening and closing block 3 can accurately illuminate the decorations or exhibits on the surface of the decorative wall, strengthen the key points, so as to better display the details of the objects, improve the display effect and viewing experience of the exhibition, and at the same time, the smoke sensor 301 and the temperature sensor 303 can monitor the smoke concentration and temperature changes in the area near the wall. Once the smoke concentration exceeds the preset safety threshold and the temperature rises rapidly nearby (i.e., an emergency such as a fire may occur), the smoke sensor 301 and the temperature sensor 303 will promptly issue an alarm and locate the relevant position, thereby effectively ensuring the safety of the exhibition hall during the exhibition.

[0052] Liquid airbags 4 are provided at the grooves of the two groups of mounting blocks in each group of sliding blocks 2. The liquid airbags 4 are filled with hydrogel liquid, and the filling amount of the hydrogel liquid in the liquid airbags 4 does not reach its upper capacity limit. A plurality of through holes are evenly penetrated through the bottom of the fixing seat 20. The positions of the plurality of through holes correspond to the openings of the inclined hollow grooves 901 on the sound-absorbing cotton 9 and the positions of the plurality of liquid airbags 4. In addition, the liquid airbag 4 is an infinity symbol "∞"-shaped structure, and two groups of through grooves are symmetrically penetrated on one side thereof. This has the following advantages.

[0053] First, the shape of the liquid airbag 4 forms a state in which liquid and gas are distributed at intervals. This multi-layer medium structure helps to isolate noise, because different media have different reflection, absorption and transmission characteristics of sound waves, thereby being able to more effectively reduce the propagation of noise. Moreover, since the hydrogel is a viscoelastic material, it can effectively consume sound energy through its internal mutual friction and damping effect, thereby effectively improving the sound insulation performance of the wall. In addition, since the hydrogel does not fill the liquid airbag 4 and can flow, it can dynamically adjust its own distribution according to the incident direction and intensity of the sound wave, and can effectively suppress the resonance phenomenon, greatly reducing the transmittance of sound, thereby further improving the sound insulation performance of the wall.

[0054] Second: When the two sides of the liquid airbag 4 are squeezed by the two groups of mounting blocks (that is, when the two groups of mounting blocks slide upward and fit together), they will be extended in the vertical direction. The air layer above the liquid airbag 4 can produce multi-form compression deformation to adapt to the different shapes of the indoor ceiling, further improving the stability of the wall after movement.

[0055] Third: When encountering a fire, the liquid airbag 4 will rupture when sensing the temperature change. At this time, the hydrogel liquid inside it will flow into the inclined hollow groove 901 of the sound-absorbing cotton 9 from the multiple groups of through holes in the fixing seat 20. Due to the poor fluidity of the hydrogel, a layer of hydrogel liquid layer will be laid along the inclined plane of the inclined hollow groove 901. This hydrogel liquid layer not only has a heat-insulating effect, but also can effectively cover the surface of the sound-absorbing cotton 9 to prevent it from directly burning, thereby ensuring the fire-proof effect of the wall (at this time, due to the presence of the hydrogel liquid layer, the expansion type fire-retardant coating 10 can be temporarily prevented from expanding). If the fire intensity is large, the flame may break through the first line of defense of the hydrogel liquid layer, causing the sound-absorbing cotton 9 to start burning. In this case, the expansion type fire-retardant coating 10 will quickly expand to prevent the wall from burning, thereby further ensuring the fire-proof performance of the wall.

[0056] In the present invention, the decorative wall is usually used as an indoor partition wall in places such as exhibition halls. The layers inside the wall are usually symmetrically designed. There is an air layer between the two groups of steel keel frames 13 on the inner side of the wall design structure. The horizontal and vertical frames of the steel keel frames 13 are arranged at non-equidistant distances. One of the steel keel frames 13 is rotated 180 degrees and completely corresponds to the other steel keel frame 13. The spaces of different areas between the horizontal and vertical frames are installed with rock wool interlayers 14, and a layer of damping rubber pads 12 are attached to the sides and then clamped using expanded perlite plates 11. This has the following advantages.

[0057] First, the air layer between the two sets of steel keel frames 13 can play a role in heat preservation and insulation, preventing the rapid transfer of heat, thereby helping to maintain the stability of the temperature in the exhibition hall, providing a more comfortable and stable indoor environment for the audience in the exhibition hall, and when the noise tries to penetrate the wall, it will encounter the air layer, resulting in reflection, refraction and attenuation effects, thereby effectively reducing the decibel value of the noise, making the exhibition hall more quiet and comfortable.

[0058] Second: Since the steel keel frame 13 and the rock wool interlayer 14 cannot be installed in a completely tight fit, sound will be transmitted through the gap. Therefore, the non-equidistant arrangement of the horizontal and vertical frames of the steel keel frame 13 and the non-corresponding installation of the two groups of steel keel frames 13 can change the facing state of the gap between the two groups of steel keel frames 13. This design effectively interrupts the direct propagation path of the sound in the gap, making it difficult for the sound to be directly transmitted from one group of steel keel frames 13 to another group of steel keel frames 13 through the gap during the propagation process. When the sound is transmitted from the gap on one group of steel keel frames 13 (the gap refers to the gap between the rock wool interlayer 14 installed on the steel keel frame 13 and the steel keel frame 13), it will collide with the surface of the rock wool interlayer 14 on the other group of steel keel frames 13, and be reflected and refracted, thereby effectively reducing the size of the sound, thereby effectively improving the sound insulation performance of the wall.

[0059] Third: In addition to being a Class A non-combustible material, the expanded perlite board 11 has an internal porous structure that can reflect sound and has a significant absorption effect on high-frequency noise, thereby effectively reducing indoor reverberation and reflected sound, thereby further improving the sound insulation performance of the wall.

[0060] Fourth: a damping rubber pad 12 is used as a sandwich between the expanded perlite board 11 and the steel keel frame 13, and a layer of flexible material is inserted between the two layers of rigid materials. When sound waves cause vibrations, the damping rubber pad 12 can absorb vibration energy through its own elastic deformation, reduce structural resonance, and effectively block the propagation of medium and low frequency noise such as human voices, thereby effectively improving the sound insulation performance of the wall. In addition, the damping rubber pad 12 not only has the functions of sound insulation and shock absorption, but also can make the fit between the expanded perlite board 11 and the steel keel frame 13 tighter, thereby further improving the sound insulation performance of the wall.

[0061] A layer of expandable fire retardant coating 10 is sprayed on the surface of the expanded perlite board 11, and one side of the expanded perlite board 11 sprayed with the expandable fire retardant coating 10 is fixedly connected to the sound-absorbing cotton 9 (i.e., the expandable fire retardant coating 10 is in close contact with the sound-absorbing cotton 9 having inclined hollow grooves 901 therein), and the outermost metal perforated plate 8 has holes that are fewer in number and smaller in density than the sound-absorbing cotton 9, but completely correspond to the partial openings on the sound-absorbing cotton 9. This has the following advantages.

[0062] First: When a fire occurs, the physical properties of the sound-absorbing cotton 9 make it relatively flammable. If the sound-absorbing cotton 9 burns, the expandable fire-retardant coating 10 will be heated and rapidly expand to form a porous carbon foam layer. The porous carbon foam layer will fill the gap between the burned sound-absorbing cotton 9 and the metal perforated plate 8, thereby effectively blocking the transfer of heat and preventing the spread of fire, thereby effectively ensuring the fire resistance of the wall.

[0063] Second: the inclined hollow groove 901 inside the sound-absorbing cotton 9 can provide a variety of reflection and absorption paths for sound waves incident at different angles, avoiding excessive concentration or reflection of sound in a specific direction, thereby reducing echo and sound focusing, and improving the sound absorption and sound insulation performance of the wall. The inclined hollow groove 901 can effectively reflect high-frequency sounds with shorter wavelengths, causing them to interfere and superimpose each other. This process helps to quickly dissipate sound energy. At the same time, the inclined hollow groove 901 can also excite the sound-absorbing cotton 9 to vibrate in a larger range. This vibration is particularly conducive to consuming the energy of low-frequency sound waves, thereby effectively enhancing the sound absorption effect of the sound-absorbing cotton 9. In addition, the inclined hollow groove 901 also cleverly increases the air circulation channel inside the sound-absorbing cotton 9, so that the sound-absorbing cotton 9 can interact with sound waves more effectively, thereby effectively improving the sound absorption efficiency of the sound-absorbing cotton 9.

[0064] Third: The regular arrangement of holes on the surface of the metal perforated plate 8 can increase the layering and artistic sense of the wall, meet the aesthetic needs of decorating the wall, and the holes on the surface of the metal perforated plate 8 can also be inserted with hooks, brackets and other devices, thereby meeting the decorative function of the wall surface. At the same time, this design avoids the need for destructive operations such as punching and gluing on the wall in traditional decoration methods, which not only protects the integrity of the wall, but also makes the change of the wall layout more convenient and flexible. Since the position of the holes on the metal perforated plate 8 corresponds to the position of some openings on the sound-absorbing cotton 9, a continuous sound-absorbing channel can be formed. When sound waves contact the metal perforated plate 8, they will be guided into the interior of the sound-absorbing cotton 9 and undergo multiple reflections and absorption inside the sound-absorbing cotton 9, thereby maximizing the consumption of sound energy. This design not only maintains the original sound-absorbing effect of the sound-absorbing cotton 9, but also further improves the sound-absorbing effect of the sound-absorbing cotton 9 through the guiding effect of the metal perforated plate 8.

[0065] By pushing the entire wall design structure, and with the cooperation of the sliding protrusions on the sliding base 7 at the bottom end thereof and the slide rails on the two groups of hydraulic parts 1 at the top of the wall structure and the slide grooves in the room, the entire wall design structure can be slid. When the wall is pushed to the specified position, the square door 6 on the hollow layer 5 is opened, and the rotating handle 16 in the square groove is turned to rotate the driving gear. The driving gear rotates to cause the rack 17 to start moving up (the two groups of mounting blocks are not in a mutually fitting state before the rack 17 moves down). The upward movement of the rack 17 drives the two groups of first gears 18 to rotate outward, and the outward rotation of the two groups of first gears 18 drives the two groups of second gears 19 to rotate inward, so that the two groups of mounting blocks slide obliquely upward until they fit each other. A rotatable opening and closing block 3 is arranged below the sliding block 2 (referring to the two groups of mounting blocks), and a smoke sensor 301, a spotlight 302 and a temperature sensor 303 are installed on the opening and closing block 3. This has the following advantages.

[0066] First: The two sets of mounting blocks slide upward diagonally so that the rubber pads on the top can be in close contact with the indoor roof, improving the stability of the wall after movement.

[0067] Second: the spotlight 302 on the opening and closing block 3 can accurately illuminate the decorations or exhibits on the surface of the decorative wall, strengthen the key points, so as to better display the details of the objects, improve the display effect and viewing experience of the exhibition, and at the same time, the smoke sensor 301 and the temperature sensor 303 can monitor the smoke concentration and temperature changes in the area near the wall. Once the smoke concentration exceeds the preset safety threshold and the temperature rises rapidly nearby (i.e., an emergency such as a fire may occur), the smoke sensor 301 and the temperature sensor 303 will promptly issue an alarm and locate the relevant position, thereby effectively ensuring the safety of the exhibition hall during the exhibition.

[0068] Liquid airbags 4 are provided at the grooves of the two groups of mounting blocks in each group of sliding blocks 2. The liquid airbags 4 are filled with hydrogel liquid, and the filling amount of the hydrogel liquid in the liquid airbags 4 does not reach its upper capacity limit. A plurality of through holes are evenly penetrated through the bottom of the fixing seat 20. The positions of the plurality of through holes correspond to the openings of the inclined hollow grooves 901 on the sound-absorbing cotton 9 and the positions of the plurality of liquid airbags 4. In addition, the liquid airbag 4 is an infinity symbol "∞"-shaped structure, and two groups of through grooves are symmetrically penetrated on one side thereof. This has the following advantages.

[0069] First, the shape of the liquid airbag 4 forms a state in which liquid and gas are distributed at intervals. This multi-layer medium structure helps to isolate noise, because different media have different reflection, absorption and transmission characteristics of sound waves, thereby being able to more effectively reduce the propagation of noise. Moreover, since the hydrogel is a viscoelastic material, it can effectively consume sound energy through its internal mutual friction and damping effect, thereby effectively improving the sound insulation performance of the wall. In addition, since the hydrogel does not fill the liquid airbag 4 and can flow, it can dynamically adjust its own distribution according to the incident direction and intensity of the sound wave, and can effectively suppress the resonance phenomenon, greatly reducing the transmittance of sound, thereby further improving the sound insulation performance of the wall.

[0070] Second: When the two sides of the liquid airbag 4 are squeezed by the two groups of mounting blocks (that is, when the two groups of mounting blocks slide upward and fit together), they will be extended in the vertical direction. The air layer above the liquid airbag 4 can produce multi-form compression deformation to adapt to the different shapes of the indoor ceiling, further improving the stability of the wall after movement.

[0071] Third: When encountering a fire, the liquid airbag 4 will rupture when sensing the temperature change. At this time, the hydrogel liquid inside it will flow into the inclined hollow groove 901 of the sound-absorbing cotton 9 from the multiple groups of through holes in the fixing seat 20.

If the fire intensity is large, the flame may break through the first line of defense of the hydrogel liquid layer, causing the sound-absorbing cotton 9 to start burning. In this case, the expansion type fire-retardant coating 10 will quickly expand to prevent the wall from burning, thereby further ensuring the fire-proof performance of the wall.
