Description

Technical Field

[0001] The invention relates to the technical field of sound insulation building structures, in particular to a modular building sound insulation structure. Background Art

[0002] Modular soundproof buildings are soundproof spaces assembled from pre-fabricated modular units. They are highly flexible and customizable, allowing them to be not only quickly built, but also adjusted and expanded as needed, making them suitable for a variety of environments and scenarios.

[0003] The modular soundproof building structure consists of multiple standardized and interchangeable modular units. Each module can contain components such as soundproof walls, ceilings, and floors. The modular design allows the space to be expanded or reduced as needed. Users can add or reduce modular units according to the noise control requirements on site. During use, if a module fails or needs to be upgraded, the single module can be replaced directly without replacing the entire system.

[0004] However, the existing modular building sound insulation mechanism also has some shortcomings and technical problems. The first is that the sound insulation effect is uneven, especially at the splicing or connection points of multiple modules. The joints and joints between different modules may become weak links for noise leakage, resulting in sound insulation effect not as expected. This is because it is difficult to achieve completely seamless sealing at the joints, and the joints between modules may not be finely processed, resulting in sound transmission through these gaps. At the same time, during long-term use, the connections between modules may become loose or deformed, resulting in reduced sound insulation performance.

[0005] The existing Chinese patent application with publication number CN109296095A discloses a modular nailed laminated wood sound insulation structural board, which can be used as floor and wall panels, belonging to the field of building technology. The surface layers on both sides are a number of vertical longitudinal surface wood boards, and a number of sandwich horizontal laminated wood boards are arranged from top to bottom between the two. When used as floor boards, each group of sandwich horizontal laminated wood boards has 2-6 layers, and when used as wall panels, each group has 1 layer. The invention fully realizes factory prefabrication, and can realize fully automatic and intelligent production, without damaging the ecological environment, greatly improves the yield rate, realizes sound insulation and heat insulation integration, maximizes internal holes, greatly improves the stiffness and strength of the board, improves the earthquake resistance, enables it to be used in high-rise housing construction, and reduces the amount of materials used; the structure is simple, and has unparalleled deformation recovery ability, the cost of building houses is low, the processing is simple, the construction is convenient, the installation efficiency is greatly improved, and the cost is reduced. Moreover, after the construction is completed, all the nails are hidden inside, which not only has good force performance, but also looks beautiful, and the durability is significantly improved.

[0006] However, since the sound insulation uniformity requirements of soundproof buildings exceed those of ordinary modular building structures, the above technical solution does not perform additional sound insulation treatment on the joints of modular building structures. Therefore, the gaps may expand during vibration and disassembly, thereby affecting the overall sound insulation effect. In addition, the existing modular building structures are cumbersome to install and use, and have poor connection stability and no buffer structure. Therefore, the service life is short and the applicable usage scenarios are single. Summary of the invention

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] 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 term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0041] Example 1 Reference Figure 1 to Figure 16 , which is the first embodiment of the present invention, provides a modular building sound insulation structure, including a substrate 100, a locking mechanism, a connecting mechanism, a locking mechanism and a switching mechanism. The gaps at the connection are blocked by the staggered arrangement of the substrates 100, and multiple locking increases the connection firmness. The number of substrates 100 can be set according to the specifications of the site to enclose sound insulation spaces of different sizes. The structure is easy to install and suitable for a variety of scenarios.

[0042] Specifically, it includes a base plate 100, the base plates 100 are staggered and spliced ​​into a layered wall, and the number of layers of the layered wall is at least two; The engaging mechanism includes a protrusion 200 and a recess 201 respectively arranged on the inner and outer sides of the substrate 100, and a sound insulation strip 202 and a sound insulation groove 203 respectively arranged on the left and right sides of the substrate 100; The connecting mechanism includes a first slideway 300 and a second slideway 301 respectively provided on the outer walls of the base plate 100. An extension rod 302 is slidably provided in the first slideway 300. A locking column 303 is slidably provided in the second slideway 301. The extension rod 302 is slidably extended to the second slideway 301 and is engaged with the locking column 303. The locking mechanism includes a clamping column 400 slidably disposed in the base plate 100, and the clamping column 400 is used to limit the second slideway 301 and the locking column 303 when they are engaged; The switching mechanism controls the rotation of the locking column 400 according to the sliding direction of the locking column 303 .

[0043] Among them, the sound insulation strip 202 is attached to the inner wall of the sound insulation groove 203, and the substrate 100 is made of sound insulation and noise reduction material. In this embodiment, the layered wall formed by the substrate 100 is two layers. In other embodiments, the number of layers of the substrate 100 is adjusted according to the requirements for the noise reduction effect.

[0044] like Fig.12As shown in the horizontal cross-sectional view, in the present invention, there are slots in six directions in total inside the base plate 100, which are respectively arranged in six mutually perpendicular directions of up, down, left, right, front and back. The left, right and front and back slots are located on the horizontal plane, which are the first slide 300 and the second slide 301 respectively. The slots in the up and down directions are respectively slidably provided with clamping columns 400. In this embodiment, the first slide 300 and the second slide 301 arranged in the left and right directions on the horizontal plane, that is, along the line connecting the sound insulation strip 202 and the sound insulation groove 203, are named as the left and right sides, and the first slide 300 and the second slide 301 arranged in the front and back direction on the horizontal plane, that is, along the line connecting the protrusion 200 and the pit 201, are named as the front and back sides.

[0045] Preferably, the sound insulation strips 202 and the sound insulation grooves 203 are both in the shape of a triangle and are interlocked and connected to 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 strips 202 and the sound insulation grooves 203, and the connection between the two substrates 100 is blocked by another layer of substrate 100, thereby preventing the problem of poor local sound insulation caused by gaps.

[0046] More preferably, in the present embodiment, both the bump 200 and the recess 201 are in the shape of rectangular columns, and a bump 200 and a recess 201 are symmetrically arranged on a single substrate 100 .

[0047] More preferably, the number of substrates 100 in the present invention can be set according to the specifications of the site of use, so as to enclose sound insulation spaces of different sizes, and the installation is simple and suitable for a variety of scenarios.

[0048] Furthermore, in this embodiment, the extension rod 302 is a screw rod, the locking column 303 is a nut, and one end of the extension rod 302 is slidably engaged in a certain substrate 100, and the other end extends to the adjacent substrate 100 and is connected to the locking column 303, thereby achieving a stable connection between each substrate 100.

[0049] Among them, Figure 4 As shown, the axes of the first slide 300 and the second slide 301 coincide with each other, and the diameter of the first slide 300 is smaller than that of the second slide 301. In this embodiment, three first slides 300 and second slides 301 are provided in linear arrays on the front and rear sides of a single substrate 100, and three first slides 300 and second slides 301 are provided in linear arrays on the left and right sides.

[0050] More preferably, the first slideway 300 and the second slideway 301 on the front and rear sides are used to connect substrates 100 on different layers, and the first slideway 300 and the second slideway 301 on the left and right sides are used to connect left and right adjacent substrates 100 on the same layer.

[0051] Example 2

[0052] Reference Figure 1 to Figure 16, which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but is different in that the connection between the substrates 100 is more stable and reliable through triple locking. At the same time, the various locks are interlocked to simplify the installation steps, provide a buffer connection, reduce the misalignment caused by vibration, improve the connection strength and stability, and ultimately prevent the generation of gaps and looseness.

[0053] Specifically, a bowl-shaped block 3001 is provided at one end of the locking column 303, and a bead-shaped block 3002 is slidably sleeved on the outer wall of the locking column 303. A bowl groove 3003 is opened at one end of the bowl-shaped block 3001 close to the locking column 303, and the bead-shaped block 3002 is movably arranged on the inner wall of the bowl groove 3003.

[0054] Among them, one end of the bowl-shaped block 3001 is a spherical surface, and the bowl groove 3003 at the other end is an annular groove. The two end surfaces of the bead-shaped block 3002 are symmetrically provided with slopes with an angle of 45°. The slope on one side of the bead-shaped block 3002 is completely embedded in the inner wall of the bowl groove 3003.

[0055] Exemplarily, the bead block 3002 is controlled by a micro airbag to slide along the outer wall of the locking column 303, and each bead block 3002 can be synchronously controlled to slide through parallel charging and discharging air pipes. When the bead block 3002 slides into the bowl groove 3003, the bowl block 3001 releases the limit of the card block 3005 and can slide freely.

[0056] A connecting cavity 3004 is provided at the connection between the first slideway 300 and the second slideway 301 , and a clamping block 3005 is provided at one end of the clamping column 400 that slides to the connecting cavity 3004 . A right-angle surface 3006 and an inclined surface 3007 are provided on the clamping block 3005 .

[0057] Preferably, the outer wall of the card column 400 is provided with a first elastic member 3008, and the two ends of the first elastic member 3008 are respectively connected to the block 3005 and the inner wall of the substrate 100, the block 3005 is a universal component, which is respectively connected to the extension rod 302 and the card column 400, and both point in the direction of the connecting cavity 3004, and the connection relationship between the block 3005 and the extension rod 302 and the card column 400 is a coaxial fixed connection. The difference is that the block 3005 on the card column 400 will rotate in the direction of rotation following the rotation of the card column 400, while the card column 400 on the extension rod 302 cannot rotate.

[0058] Furthermore, the first elastic member 3008 is a spring, which is used to always push the card column 400 to slide downward into the connecting cavity 3004, and the card column 400 is slidably disposed inside the substrate 100 along a direction perpendicular to the horizontal plane.

[0059] The block 3005 is cylindrical in shape, and the right-angle surface 3006 and the inclined surface 3007 are both opened on the block 3005 by cutting, so that as the block 3005 rotates 180 degrees, the right-angle surface 3006 and the inclined surface 3007 can be switched.

[0060] More preferably, the first slides 300 on the front and rear sides and the first slides 300 on the left and right sides are vertically distributed and their common intersection is located at the center point of the connecting cavity 3004. The connecting cavity 3004 has a total of six slots, and the slots are vertically distributed to each other. The upper and lower slots are provided with clamping columns 400, the front and rear slots are provided with a pair of coaxially arranged locking columns 303 and extension rods 302, and the left and right slots are also provided with a pair of locking columns 303 and extension rods 302.

[0061] Preferably, a cylinder 3026 is fixedly sleeved on the locking column 303 , a first slide groove 3027 is formed on the cylinder 3026 , a locking groove 3028 is formed at the bottom of the first slide groove 3027 , and a locking block 3009 is formed at one end of the extension rod 302 extending to the adjacent substrate 100 .

[0062] More preferably, if Fig.15 As shown, the first slide groove 3027 and the locking block 3009 are both waist-shaped, and 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 with the center. When the locking block 3009 slides to the lowest point of the first slide groove 3027, it can be rotated into the locking groove 3028 to achieve the locking connection between the locking column 303 and the extension rod 302.

[0063] A buffer cavity 3012 is provided inside the extension rod 302 , a tray 3011 is fixedly provided on the inner wall of the buffer cavity 3012 , a buffer cylinder 3013 is slidably provided inside the buffer cavity 3012 , and a second slide groove 3014 , a first rotation groove 3015 and a second rotation groove 3016 are provided inside the buffer cylinder 3013 .

[0064] Among them, the buffer cavity 3012 is a cylindrical cavity, the buffer cylinder 3013 is a cylindrical hollow cylinder, the first rotating groove 3015 and the second rotating groove 3016 are respectively vertically provided at both ends of the second slide groove 3014, 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 simultaneously coaxially arranged with the buffer cavity 3012.

[0065] More preferably, a driving cylinder 3017 is slidably provided on the inner wall of the buffer cylinder 3013, and a sliding block 3018 is symmetrically provided on the outer wall of the driving cylinder 3017. The extension rod 302 also includes a locking column 3019 fixed to the axis of the driving cylinder 3017, and a locking block 3009 is provided at the end of the locking column 3019.

[0066] A sliding ring 3021 is provided on the inner wall of the buffer cylinder 3013 and the outer wall of the driving cylinder 3017 . A sliding column 3022 is provided on the inner wall of the sliding ring 3021 . A spiral groove 3023 is provided on the outer wall of the driving cylinder 3017 . The sliding column 3022 is slidably provided on the inner wall of the spiral groove 3023 .

[0067] More preferably, a support column 3024 is fixedly provided on the tray 3011 , and the support column 3024 slides through between the inner wall of the buffer cylinder 3013 and the outer wall of the driving cylinder 3017 and is fixedly connected to the sliding ring 3021 .

[0068] Preferably, a second elastic member 3025 is sleeved on the outer wall of the support column 3024 , and two ends of the second elastic member 3025 are respectively connected to the outer wall of the buffer cylinder 3013 and the outer wall of the tray 3011 .

[0069] The second elastic member 3025 is a spring, which is used to pull the buffer tube 3013 and the buffer cavity 3012 together for reset after relative displacement, thereby playing a buffering role, eliminating the tiny vibrations generated between the substrates 100, and preventing the gap at the connection from rigid fracture.

[0070] Among them, in other embodiments, the buffer cylinder 3013 protrudes from the outer wall of the extension rod 302 when it is set, and the buffer cylinder 3013 and the buffer cavity 3012 are filled with gas. Under the action of air pressure, the second elastic member 3025 is always in an elongated stage, pulling the buffer cylinder 3013 and the inner wall of the buffer cavity 3012 closer, and the thrust of the air pressure on the buffer cylinder 3013 is balanced with the pulling force of the second elastic member 3025 in the initial state. When the buffer cylinder 3013 and the extension rod 302 produce relative displacement, part of the gas is discharged through the one-way valve, and the second elastic member 3025 still maintains balance. When the buffer cylinder 3013 and the buffer cavity 3012 tend to separate, the second elastic member 3025 will apply a larger pulling force to offset it, thereby realizing the buffering function at the connection between the two substrates 100.

[0071] In summary, when in use, the two substrates 100 on the same layer are assisted in positioning and connected closely by the sound insulation strips 202 and the sound insulation grooves 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 column 303 and extends to the second slide 301 on the left substrate 100.

[0072] At the same time, the extension rod 302 continues to move. When the buffer cylinder 3013 abuts against the cylinder 3026, the buffer cylinder 3013 stops moving and is relatively displaced with the extension rod 302 that continues to move, thereby pushing the support column 3024 to move through the tray 3011. At this time, the sliding ring 3021 follows the movement of the driving cylinder 3017 and the locking column 3019, driving the locking block 3009 to slide along the first sliding groove 3027 in the cylinder 3026.

[0073] When the locking block 3009 slides to the bottom of the first slide groove 3027 and cannot move further, the slide post 3022 on the sliding ring 3021 slides along the spiral groove 3023, driving the driving cylinder 3017 to rotate, so that the slider 3018 slides from the bottom of the second slide groove 3014 to 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 and the engagement of the slider 3018 and the second rotating groove 3016 achieve synchronous double locking. At the same time, the second elastic member 3025 realizes a buffer connection between the two substrates 100, thereby reducing the misalignment caused by vibration, improving the connection strength and stability, and ultimately preventing gaps and looseness.

[0074] At the same time, reference Figure 4 , the block 3005 in the direction of the extension rod 302 will also push the locking column 303 to continue to slide to the left, and slide along the inclined surface 3007 of the block 3005 in the direction of the column 400 until it engages with the right-angle surface 3006 to form a third lock, and after the bowl-shaped block 3001 moves, it will also push the extension rod 302 in the left substrate 100 to continue to move left, and the connection of each substrate 100 is achieved in this reciprocating manner. At this time, the block 3005 in the direction of the extension rod 302 in the left and right directions provides thrust, and the block 3005 in the front and back directions and in the direction of the column 400 engages with the bowl-shaped block 3001.

[0075] Exemplarily, in this embodiment, there are four card blocks 3005, two in the up and down direction, and one each in the front and back direction and the left and right direction. The two card blocks 3005 in the up and down direction always play a locking role, and the functions of the other two card blocks 3005 change according to the connection method.

[0076] Furthermore, a block 3005 is also provided at one end of the extension rod 302 close to the connecting cavity 3004, and the direction of the 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 blocks 3005 are in a locked state with the locking column 303, thereby enriching the connection methods between the substrates 100, and performing connections in different directions according to the usage scenarios, adapting to different usage scenarios, and improving compatibility.

[0077] Specifically, a block 3005 is also provided at one end of the extension rod 302 close to the connecting cavity 3004, and the blocks 3005 on the two vertically arranged extension rods 302 are in opposite directions. A gear 4001 is provided at the upper end of the clamping column 400, and a rack 4002 is meshed with the outer wall of the gear 4001.

[0078] Among them, the block 3005 on the clamping column 400 has two adjustable directions, which correspond to the directions of the block 3005 on the two extension rods 302 respectively. The block 3005 can switch the direction after rotating 180°. There are two symmetrical racks 4002, and both slide in the direction of 45° horizontal angle with the extension rod 302.

[0079] Furthermore, a sliding sleeve 4003 is vertically disposed at the end of the rack 4002 , and a linkage rod 4004 is disposed at the end surface of the locking column 303 . The linkage rod 4004 is slidably disposed in the base plate 100 and one end of the linkage rod 4004 is slidably disposed in the sliding sleeve 4003 .

[0080] Among them, there are two linkage rods 4004, which extend to two vertically arranged second slides 301 respectively and are connected to the locking column 303. A single substrate 100 can be connected to the adjacent substrate 100 in the same layer through the second slide 301 arranged along the left-right direction, and can also be connected to the substrate 100 in another layer through the second slide 301 arranged along the front-to-back direction. The connection between adjacent substrates 100 can be in three states: left-to-right connection to left-to-right, left-to-right connection to front-to-back, or front-to-back connection to front-to-back. The front-to-back connected substrates 100 are isolated in the vertical direction and can also be layered in the horizontal direction.

[0081] More preferably, in other embodiments, one set of the clamping column 400 may be provided. In this embodiment, two sets of the clamping column 400 are provided in the up-and-down direction, thereby improving the connection firmness.

[0082] In summary, if Figure 4 As shown, when in use, when the substrates 100 need to be connected adjacent to each other in the same layer or in different layers, the extension rod 302 needs to slide into the second slide 301 from two corresponding directions respectively. When the substrates 100 need to be connected adjacent to each other in the same layer, the extension rod 302 enters the second slide 301 in the left and right directions, pushes the locking column 303 to slide along the left and right directions, and drives the linkage rod 4004 to slide. At this time, the linkage rods 4004 symmetrically arranged in two directions move at the same time, and 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, so that 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.

[0083] At this time, the rack 4002 will also drive the gear 4001 to rotate counterclockwise, and the upper and lower clamping columns 400 and their supporting parts are symmetrically arranged. The upper and lower clamping columns 400 can rotate synchronously at this time, and synchronously adjust the direction and posture of the clamping block 3005 until the inclined surface 3007 of the clamping block 3005 is facing the direction of the second slide 301, thereby adjusting the direction of the two clamping blocks 3005 distributed above and below until they are in the same direction as the clamping blocks 3005 on the front and rear extension rods 302. At this time, the three clamping blocks 3005 synchronously limit the locking column 303 to improve the limiting effect, and when the locking column 303 moves, it pushes the left and right blocks 3005 and the extension rod 302 to move, so as to carry out the subsequent connection process, thereby increasing the connection methods of the substrate 100, and can be connected in different directions according to the usage scenarios, adapt to different usage scenarios, and improve compatibility.
