Description

Technical Field

[0001] This invention relates to the field of soundproof building structure technology, and in particular to a modular building soundproof structure. Background Technology

[0002] Modular soundproof buildings are soundproof spaces assembled from pre-manufactured modular units. They are highly flexible and customizable, allowing for rapid construction and adjustment and expansion as needed, making them suitable for various environments and scenarios.

[0003] Modular soundproof building structures consist of multiple standardized, interchangeable modular units. Each module can contain components such as soundproof walls, ceilings, and floors. The modular design allows for spatial expansion or reduction as needed. Users can add or remove modular units according to on-site noise control requirements. If a module malfunctions or needs to be upgraded, the individual module can be replaced directly without replacing the entire system.

[0004] However, existing modular building sound insulation mechanisms also have some shortcomings and technical problems. First, the sound insulation effect is uneven, especially at the splicing or connection of multiple modules. The seams and joints between different modules may become weak points for noise leakage, resulting in a less than expected sound insulation effect. This is because it is difficult to achieve a completely seamless seal at the connection, and the treatment of the seams between modules may not be precise enough, allowing sound to pass through these gaps. At the same time, during long-term use, the connection between modules may loosen or deform, leading to a decrease in sound insulation performance.

[0005] Chinese patent application CN109296095A discloses a modular nail-laminated layered sound insulation structural panel, which can be used as a floor slab and wall panel, belonging to the field of building technology. Both sides consist of several vertically stacked wooden planks, with several horizontally stacked wooden planks sandwiched between them from top to bottom. When used as a floor slab, each group of horizontally stacked wooden planks has 2-6 layers; when used as a wall panel, each group has 1 layer. This invention achieves complete factory prefabrication and fully automated, intelligent production, without damaging the ecological environment, significantly increasing the yield rate, achieving integrated sound and heat insulation, maximizing internal pores, greatly improving the rigidity and strength of the panel, enhancing seismic resistance, making it suitable for high-rise building construction, and reducing material usage. The structure is simple, with unparalleled deformation recovery capability, resulting in low construction costs, simple processing, convenient construction, significantly improved installation efficiency, and reduced costs. Furthermore, after construction, all nails are concealed, resulting in not only good load-bearing performance but also aesthetic appeal and significantly improved durability.

[0006] However, because soundproof buildings have higher requirements for sound insulation uniformity than ordinary modular building structures, the above-mentioned technical solutions do not provide additional sound insulation treatment at the joints of modular building structures. Therefore, during vibration and disassembly, gaps may widen, thus affecting the overall sound insulation effect. Furthermore, existing modular building structures are cumbersome to install and use, have poor connection stability, and lack a buffer structure, resulting in a short service life and limited applicability to a single application scenario.

[0047] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0048] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0049] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0050] Example 1

[0051] Reference Figures 1-16 This is the first embodiment of the present invention. This embodiment provides a modular building sound insulation structure, including a base plate 100, a locking mechanism, a connecting mechanism, a locking mechanism, and a switching mechanism. The gaps at the connection points are covered by the staggered arrangement of each base plate 100. At the same time, multiple locking mechanisms increase the connection strength. The number of base plates can be set according to the requirements of the site to form sound insulation spaces of different sizes. It is easy to install and suitable for various scenarios.

[0052] Specifically, it includes a substrate 100, which is staggered to form a layered wall, and the layered wall has at least two layers.

[0053] The engaging mechanism includes protrusions 200 and recesses 201 respectively provided on the inner and outer sides of the substrate 100, and sound insulation strips 202 and sound insulation grooves 203 respectively provided on the left and right sides of the substrate 100.

[0054] The connecting mechanism includes a first slide rail 300 and a second slide rail 301 respectively opened on the outer walls of the four sides of the substrate 100. An extension rod 302 is slidably provided in the first slide rail 300, and a locking post 303 is slidably provided in the second slide rail 301. The extension rod 302 slidably extends into the second slide rail 301 of the adjacent substrate 100 and engages with the locking post 303.

[0055] The locking mechanism includes a locking post 400 slidably disposed in the base plate 100, which limits the locking post 303 when it engages with the locking post 303 in the second slide 301.

[0056] The switching mechanism controls the rotation of the locking pin 400 according to the sliding direction of the locking pin 303.

[0057] The sound insulation strip 202 is attached to the inner wall of the sound insulation groove 203. The substrate 100 is made of sound insulation and noise reduction material. In this embodiment, the layered wall formed by splicing the substrate 100 has two layers. In other embodiments, the number of splicing layers of the substrate 100 is adjusted according to the requirements of the noise reduction effect.

[0058] like Figure 12 As shown in the horizontal cross-sectional view, the substrate 100 of this invention has six slots in total, which are arranged in six mutually perpendicular directions: up, down, left, right, front, and back. The left and right slots and the front and back slots are located on the horizontal plane and are respectively the first slide rail 300 and the second slide rail 301. The slots in the up and down directions are respectively equipped with locking posts 400. In this embodiment, the first slide rail 300 and the second slide rail 301 arranged in the left and right direction on the horizontal plane, that is, along the line connecting the sound insulation strip 202 and the sound insulation groove 203, are named the left and right side. The first slide rail 300 and the second slide rail 301 arranged in the front and back direction on the horizontal plane, that is, along the line connecting the protrusion 200 and the recess 201, are named the front and back side.

[0059] Preferably, the sound insulation strip 202 and the sound insulation groove 203 are both in the shape of a triangular shape and are interlocked with each other. In this embodiment, the adjacent substrates 100 on the left and right sides of the same layer are connected by the sound insulation strip 202 and the sound insulation groove 203, and the connection between the two substrates 100 is blocked by another substrate 100, thereby preventing the problem of poor local sound insulation effect caused by gaps.

[0060] More preferably, in this embodiment, both the bump 200 and the recess 201 are rectangular pillar shapes, and a bump 200 and a recess 201 are symmetrically provided on a single substrate 100.

[0061] More preferably, the number of substrates 100 in this invention can be set according to the requirements of the site specifications, thereby forming soundproof spaces of different sizes, and the installation is simple and suitable for a variety of scenarios.

[0062] Furthermore, in this embodiment, the extension rod 302 is a screw, the locking post 303 is a nut, and one end of the extension rod 302 is slidably engaged in a certain substrate 100, while the other end extends to an adjacent substrate 100 and is connected to the locking post 303, thereby achieving a stable connection between each substrate 100.

[0063] Among them, such as Figure 4 As shown, the axes of the first slide rail 300 and the second slide rail 301 coincide with each other. The diameter of the first slide rail 300 is smaller than that of the second slide rail 301. In this embodiment, three first slide rails 300 and two slide rails 301 are linearly arrayed on the front and rear sides of a single substrate 100, and three first slide rails 300 and two slide rails 301 are linearly arrayed on the left and right sides.

[0064] More preferably, the first slide rail 300 and the second slide rail 301 on the front and rear sides are used to connect substrates 100 of different layers, and the first slide rail 300 and the second slide rail 301 on the left and right sides are used to connect adjacent substrates 100 of the same layer.

[0065] Example 2

[0066] Reference Figures 1-16 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the connection between the substrates 100 is more stable and reliable through triple locking. At the same time, the locks are interlocked to simplify the installation steps and provide a buffer connection to reduce the misalignment caused by vibration, improve the connection strength and stability, and ultimately prevent the generation of gaps and loosening.

[0067] Specifically, a bowl-shaped block 3001 is provided at one end of the locking post 303, and a bead-shaped block 3002 is slidably sleeved on the outer wall of the locking post 303. A bowl groove 3003 is opened at one end of the bowl-shaped block 3001 near the locking post 303, and the bead-shaped block 3002 is movably disposed on the inner wall of the bowl groove 3003.

[0068] Among them, one end of the bowl-shaped block 3001 is a spherical surface, and the other end of the bowl groove 3003 is an annular groove. The two ends of the bead-shaped block 3002 are symmetrically provided with slopes, the slope angle is 45°, and one side of the slope of the bead-shaped block 3002 is completely fitted into the inner wall of the bowl groove 3003.

[0069] For example, the bead block 3002 is controlled by a micro airbag to slide along the outer wall of the locking post 303. The sliding of each bead block 3002 can be controlled synchronously through parallel inflation and deflation pipes. When the bead block 3002 slides into the bowl groove 3003, the bowl block 3001 can be released from the limit of the locking block 3005 and slide freely.

[0070] The first slide 300 and the second slide 301 are connected by a connecting cavity 3004. The end of the locking post 400 that slides to the connecting cavity 3004 is provided with a locking block 3005. The locking block 3005 is provided with a right angle surface 3006 and an inclined surface 3007.

[0071] More preferably, the outer wall of the locking post 400 is fitted with a first elastic element 3008. The two ends of the first elastic element 3008 are respectively connected to the locking block 3005 and the inner wall of the base plate 100. The locking block 3005 is a general-purpose component, which is connected to the extension rod 302 and the locking post 400 respectively, and both point in the direction of the communicating cavity 3004. The connection relationship between the locking block 3005, the extension rod 302, and the locking post 400 is a coaxial fixed connection. The difference is that the locking block 3005 on the locking post 400 will rotate with the rotation of the locking post 400, while the locking block 3005 on the extension rod 302 cannot rotate.

[0072] Furthermore, the first elastic element 3008 is a spring, which is used to continuously push the locking post 400 downward to slide into the communicating cavity 3004. The locking post 400 is slidably disposed inside the substrate 100 in a direction perpendicular to the horizontal plane.

[0073] The card block 3005 is cylindrical in shape, and the right angle surface 3006 and the inclined surface 3007 are both cut on the card block 3005. As the card block 3005 rotates 180°, the right angle surface 3006 and the inclined surface 3007 can be switched.

[0074] More preferably, the first slide rails 300 on the front and rear sides and the first slide rails 300 on the left and right sides are vertically distributed and their common intersection point is located at the center point of the connecting cavity 3004. The connecting cavity 3004 has a total of six slots, each slot is vertically distributed to each other. The upper and lower slots are provided with locking posts 400, the front and rear slots are provided with a pair of locking posts 303 and extension rods 302 arranged coaxially, and the left and right slots are also provided with a pair of locking posts 303 and extension rods 302.

[0075] Preferably, a cylinder 3026 is also fixedly sleeved on the locking post 303, a first sliding groove 3027 is provided on the cylinder 3026, a locking groove 3028 is provided at the bottom of the first sliding groove 3027, and a locking block 3009 is provided at one end of the extension rod 302 extending to the adjacent substrate 100.

[0076] Better, such as Figure 15 As shown, both the first slide groove 3027 and the locking block 3009 are waist-shaped. The locking block 3009 slides up and down along the first slide groove 3027. The locking groove 3028 is a fan-shaped groove arranged symmetrically at the center. When the locking block 3009 slides to the lowest point of the first slide groove 3027, it can rotate into the locking groove 3028 to realize the engagement of the locking post 303 and the extension rod 302.

[0077] The extension rod 302 has a buffer cavity 3012 inside, a tray 3011 is fixedly installed on the inner wall of the buffer cavity 3012, a buffer cylinder 3013 is slidably installed in the buffer cavity 3012, and a second sliding groove 3014, a first rotating groove 3015 and a second rotating groove 3016 are opened in the buffer cylinder 3013.

[0078] The buffer cavity 3012 is a cylindrical cavity, the buffer cylinder 3013 is a cylindrical hollow cylinder, and the two ends of the second slide groove 3014 are respectively provided with a first rotating groove 3015 and a second rotating groove 3016 perpendicularly. The direction of the second slide groove 3014 is parallel to the axial direction of the buffer cavity 3012, and the first rotating groove 3015 and the second rotating groove 3016 are coaxially arranged with the buffer cavity 3012.

[0079] More preferably, the inner wall of the buffer cylinder 3013 is slidably provided with a drive cylinder 3017, the outer wall of the drive cylinder 3017 is symmetrically provided with sliders 3018, and the extension rod 302 also includes a locking post 3019 fixedly provided on the axis of the drive cylinder 3017, and a locking block 3009 is provided at the end of the locking post 3019.

[0080] The inner wall of the buffer cylinder 3013 and the outer wall of the drive cylinder 3017 are provided with a sliding ring 3021. The inner wall of the sliding ring 3021 is provided with a sliding column 3022, and the outer wall of the drive cylinder 3017 is provided with a spiral groove 3023. The sliding column 3022 is slidably disposed on the inner wall of the spiral groove 3023.

[0081] More preferably, a support column 3024 is fixedly provided on the tray 3011, and the support column 3024 slides through the inner wall of the buffer cylinder 3013 and the outer wall of the drive cylinder 3017 and is fixedly connected to the sliding ring 3021.

[0082] Preferably, a second elastic element 3025 is sleeved on the outer wall of the support column 3024, and the two ends of the second elastic element 3025 are respectively connected to the outer wall of the buffer cylinder 3013 and the outer wall of the tray 3011.

[0083] The second elastic element 3025 is a spring, which is used to pull the buffer cylinder 3013 and the buffer cavity 3012 closer together to reset after relative displacement occurs, thereby playing a buffering role, eliminating the small vibrations generated between the various substrates 100, and preventing rigid breakage of the gap at the connection.

[0084] In other embodiments, the buffer cylinder 3013 protrudes from the outer wall of the extension rod 302 during installation. Gas is filled inside the buffer cylinder 3013 and the buffer cavity 3012. Under the action of gas pressure, the second elastic element 3025 is always in the elongated stage, pulling the inner walls of the buffer cylinder 3013 and the buffer cavity 3012 closer together. In the initial state, the pushing force of the gas pressure on the buffer cylinder 3013 is balanced with the pulling force of the second elastic element 3025. When the buffer cylinder 3013 and the extension rod 302 have relative displacement, some gas is discharged through the one-way valve, and the second elastic element 3025 still remains balanced. When the buffer cylinder 3013 and the buffer cavity 3012 tend to separate, the second elastic element 3025 will apply a greater pulling force to counteract it, thereby realizing the buffering function at the connection of the two substrates 100.

[0085] In summary, during use, the two substrates 100 on the same layer are positioned and connected close together by the sound insulation strip 202 and the sound insulation groove 203. At this time, the extension rod 302 located in the first slide 300 on the right substrate 100 is pushed outward by the locking post 303 and extends into the second slide 301 on the left substrate 100.

[0086] Meanwhile, the extension rod 302 continues to move. When the buffer cylinder 3013 comes into contact with the cylinder 3026, the buffer cylinder 3013 stops moving and is relatively displaced with the continuing to move extension rod 302. This causes the support column 3024 to move through the tray 3011. At this time, the sliding ring 3021 moves with the drive cylinder 3017 and the locking column 3019, causing the locking block 3009 to slide along the first groove 3027 inside the cylinder 3026.

[0087] When the locking block 3009 slides to the bottom of the first slide groove 3027 and can no longer move, the sliding post 3022 on the sliding ring 3021 slides along the spiral groove 3023, driving the drive cylinder 3017 to rotate. As a result, the slider 3018 slides from the bottom of the second slide groove 3014 into the second rotating groove 3016, driving the locking block 3009 to rotate and engage in the locking groove 3028. The locking of the locking groove 3028 and the locking block 3009, as well as the engagement of the slider 3018 and the second rotating groove 3016, achieve synchronous double locking. At the same time, the second elastic element 3025 achieves a buffer connection between the two substrates 100, reducing the misalignment amplitude caused by vibration, improving the connection strength and stability, and ultimately preventing gaps and loosening.

[0088] Meanwhile, reference Figure 4 The locking block 3005 in the direction of the extension rod 302 will also push the locking post 303 to continue sliding to the left, and slide along the inclined surface 3007 of the locking block 3005 in the direction of the locking post 400 until it engages with the right angle surface 3006, forming a third lock. After the cup-shaped block 3001 moves, it will also push the extension rod 302 in the left substrate 100 to continue moving to the left. This process is repeated to achieve the connection of each substrate 100. At this time, the locking block 3005 in the direction of the extension rod 302 in the left and right directions provides a pushing force, while the locking block 3005 in the direction of the front and back and the direction of the locking post 400 engages with the cup-shaped block 3001.

[0089] For example, in this embodiment, there are four locking blocks 3005, two in the vertical direction and one each in the front-back and left-right directions. The two locking blocks 3005 in the vertical direction always play a locking role, while the function of the other two locking blocks 3005 changes depending on the connection method.

[0090] Furthermore, a locking block 3005 is also provided at one end of the extension rod 302 near the connecting cavity 3004, and the direction of the locking block 3005 is adjusted according to the insertion direction of the extension rod 302 on the substrate 100, so as to always ensure that the three locking blocks 3005 are engaged with the locking post 303, which enriches the connection methods between the substrates 100, allows for connection in different directions according to the usage scenario, adapts to different usage scenarios, and improves compatibility.

[0091] Specifically, the extension rod 302 is also provided with a locking block 3005 at one end near the connecting cavity 3004. The locking blocks 3005 on the two vertically arranged extension rods 302 are in opposite directions. The upper end of the locking post 400 is provided with a gear 4001, and the outer wall of the gear 4001 is meshed with a rack 4002.

[0092] The locking block 3005 on the locking post 400 has two adjustable directions, corresponding to the directions of the locking blocks 3005 on the two extension rods 302 respectively. The locking block 3005 can switch directions after rotating 180°. The rack 4002 is symmetrically provided with two racks, and both slide along a direction with a horizontal angle of 45° with the extension rod 302.

[0093] Furthermore, a sliding sleeve 4003 is vertically provided at the end of the rack 4002, and a linkage rod 4004 is provided on the end face of the locking post 303. The linkage rod 4004 is slidably disposed within the base plate 100 and one end is slidably disposed within the sliding sleeve 4003.

[0094] There are two linkage rods 4004, which extend into two vertically arranged second slide rails 301 and are connected to the locking post 303. A single substrate 100 can be connected to an adjacent substrate 100 in the same layer through the second slide rail 301 arranged in the left-right direction, or it can be connected to a substrate 100 in another layer through the second slide rail 301 arranged in the front-back direction. The connection between adjacent substrates 100 can be in three states: left-right connection to left-right, left-right connection to front-back, or front-back connection to front-back. The substrates 100 connected in the front-back direction are isolated in the vertical direction and can also be layered in the horizontal direction.

[0095] More preferably, in other embodiments, one set of locking posts 400 can be provided. In this embodiment, two sets of locking posts 400 are provided in the vertical direction, thereby improving the connection strength.

[0096] In summary, as Figure 4 As shown, when it is necessary to connect adjacent substrates 100 in the same layer or connect substrates 100 in different layers during use, the extension rod 302 needs to slide into the second slide rail 301 from two corresponding directions respectively. When it is necessary to connect adjacent substrates 100 in the same layer, the extension rod 302 enters the second slide rail 301 in the left and right directions, pushes the locking pin 303 to slide in the left and right directions, and drives the linkage rod 4004 to slide. At this time, the linkage rods 4004 symmetrically arranged in the two directions move simultaneously. The movement of the linkage rod 4004 in the sliding sleeve 4003 is decomposed into sliding in the direction parallel to the sliding sleeve 4003 and moving in the direction perpendicular to the sliding sleeve 4003. Thus, the linkage rod 4004 slides in the sliding sleeve 4003 and drives the rack 4002 to move synchronously in the direction perpendicular to the sliding sleeve 4003.

[0097] At this time, the rack 4002 will also drive the gear 4001 to rotate counterclockwise. The upper and lower locking pins 400 and their matching connected parts are symmetrically arranged. The upper and lower locking pins 400 can rotate synchronously at this time, and synchronously adjust the orientation of the locking block 3005 until the inclined surface 3007 of the locking block 3005 faces the direction of the second slide rail 301. This adjusts the orientation of the two upper and lower locking blocks 3005 until they are in the same orientation as the locking blocks 3005 on the front and rear extension rod 302. At this time, the three locking blocks 3005 synchronously limit the locking pin 303, improving the limiting effect. When the locking pin 303 moves, it pushes the left and right locking blocks 3005 and extension rod 302 to move, thereby performing subsequent connection processes. This increases the connection methods of the base plate 100, which can be connected in different directions according to the usage scenario, adapting to different usage scenarios and improving compatibility.
