Description

Technical Field

[0001] This invention relates to the field of soundproof wall construction technology, specifically a lightweight composite soundproof wall. Background Technology

[0002] Currently, most soundproof walls used in the construction industry adopt monolithic casting or fixed splicing structures. Their processing and installation are complex, and disassembly and maintenance are difficult. Once the wall is damaged, it often needs to be completely demolished and rebuilt, which is not only time-consuming and labor-intensive, but also results in a large waste of materials. The assembly flexibility of existing soundproof walls is poor, and most can only achieve single-dimensional laying. It is difficult to expand laterally or stack vertically according to the actual space requirements, and cannot adapt to the construction scenarios of walls with different areas and heights. At the same time, the wall thickness in some factory buildings is mostly fixed prefabricated or set, which cannot be adjusted according to sound insulation needs, resulting in a single sound insulation effect that is difficult to meet diverse sound insulation requirements. In particular, for composite sound insulation panels, one side is an alloy and the other side is sound insulation material. They can only be used for wall laying. If a sound insulation wall is built alone, the sound insulation material will be exposed, affecting the aesthetics and service life. Summary of the Invention

The upper and lower side walls of the several connecting arms are provided with a first mating opening that is the same as the slide groove. The middle of the connecting arm is provided with a second mating opening that corresponds to the adapter groove near both ends. The several connecting arms can be detachably installed between a pair of card seats and are respectively mated with the card seats. The several connecting arms are respectively fitted onto the adapter rod through the second mating opening. The front and rear side walls of the several connecting arms are provided with slots near the middle of the upper and lower ends. The several claws are all L-shaped. The several claws are respectively fixed through the first mating opening of the connecting arm, and the two ends of the claws are respectively movably inserted into the slide groove at the opposite end of the card seat. The two ends of the several connecting ribs can be detachably inserted into the slots of one pair of connecting arms.

[0007] Preferably, the bridge structure includes a pair of support plates, a pair of sliders, and a pair of second bolts; one end of each pair of support plates is L-shaped and fits into a sliding groove, one end of each pair of support plates can be detachably inserted into the sliding groove of the card seat, and the support plates are located between parallel card seats; the other ends of each pair of support plates are staggered and fitted on the upper and lower sides, one end of one support plate is provided with a pair of adjustment grooves, the pair of sliders are movably embedded in the adjustment grooves, and the pair of second bolts movably pass through the other end of the other support plate, and the second bolts are screwed into the sliders.

[0008] Preferably, the relative width of one end of the tray can be adjusted by moving the slider in the adjustment groove, thereby realizing the spacing of the card holder and conforming to the construction of walls of different thicknesses.

[0017] 4. Strong scalability of sound insulation effect: The bridge structure and the snap-fit ​​structure work together to form an inner cavity space, which can be used to add other sound insulation materials. Combined with the multi-layer laying design, the overall sound insulation performance can be flexibly improved according to the sound insulation needs, enhancing the controllability and scalability of the sound insulation effect.

[0018] 5. Excellent overall flexibility and practicality: The detachable design of the snap-fit ​​and bridge structure, as well as the adjustable and splicable characteristics of each component, greatly improves the flexibility of the overall laying, making it easy to install, adjust and maintain, while taking into account structural stability and functional expandability.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-7 The present invention provides a technical solution: a lightweight composite soundproof wall, comprising a composite soundproof panel 1, a snap-fit ​​structure 2, and a connecting bridge structure 3; the snap-fit ​​structure 2 can be detachably fastened to the upper and lower ends of the composite soundproof panel 1, and the connecting bridge structure 3 can be detachably disposed between the snap-fit ​​structures 2; the snap-fit ​​structure 2 is used to snap-fit ​​and limit the composite soundproof panel 1, and to support and arrange the composite soundproof panel 1; the snap-fit ​​structure 2 can be assembled relatively laterally and longitudinally, and the connecting bridge structure 3 is used to connect the snap-fit ​​structures 2 in series.

[0029] like Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, as a preferred embodiment, the snap-fit ​​structure 2 further includes several snap-fit ​​seats 21, several adapter rods 22, several first bolts 23, several snap-fit ​​arms 24, several snap-fit ​​claws 25, and several connecting ribs 26; the snap-fit ​​seats 21 are all concave, and symmetrical L-shaped grooves 4 are provided through the middle of the upper walls at both ends of each snap-fit ​​seat 21; trapezoidal adapter grooves 5 are provided through the inner sidewalls at both ends of each snap-fit ​​seat 21; the snap-fit ​​seats 21 can be disassembled and connected in a relatively horizontal series; the snap-fit ​​seats 21 can be disassembled and connected symmetrically; and the grooves 4 of the snap-fit ​​seats 21 are located at the top and bottom respectively; the several adapter rods 22 are all concave, and symmetrical L-shaped grooves 4 are provided through the middle of the upper walls at both ends of each snap-fit ​​seat 21. Both ends of the connecting rod 22 are movably inserted into the adapter groove 5 at one end of a pair of card seats 21. Several first bolts 23 are countersunk through both ends of the connecting rod 22, and the first bolts 23 are tightened against the inner wall of the adapter groove 5. Several locking arms 24 are rectangular rods, and the length of the locking arms 24 is the same as the height of the side wall of the card seat 21. The upper and lower side walls of several locking arms 24 are provided with first mating openings 6, which are the same as the sliding groove 4. The middle part of the locking arms 24 near both ends is provided with second mating openings 7, which are corresponding to the adapter groove 5. Several locking arms 24 can be detachably installed between a pair of card seats 21. Each of the several locking arms 24 is fitted onto the adapter rod 22 through the second mating port 7, and slots 8 are provided on the front and rear side walls of the locking arms 24 near the middle of the upper and lower ends. Several L-shaped locking claws 25 are fixedly inserted through the first mating port 6 of the locking arms 24, and both ends of the claws 25 are movably inserted into the sliding grooves 4 at opposite ends of the locking arms 21. Several connecting ribs 26 are detachably inserted into the slots 8 of one pair of locking arms 24. The adapter rod 22 is inserted into the adapter slots 5 of two opposing locking arms 21, and the first... Bolt 23 tightens and fixes the adapter rod 22, causing the card seat 21 to extend laterally along the X-axis. The card claw 25 can be used to set the card arm 24 between the card seats 21, and the card claw 25 fits with the slide groove 4. At the same time, the card arm 24 can be fitted onto the adapter rod 22. The card arm 24 and the adapter rod 22 form a relatively perpendicular intersection, realizing the stable assembly of the card seat 21 along the Y-axis. This ensures that the composite sound insulation board 1 remains stable during construction due to the force applied to the upper and lower ends. The connecting rib 26 can connect the card arms 24 set at the upper and lower ends of the longitudinally arranged composite sound insulation board 1, further ensuring the stability of the assembly.

[0030] More specifically, the snap-fit ​​structure 2 can realize the horizontal single-layer laying, horizontal multi-layer laying and vertical stacking laying of the composite sound insulation board 1, and all components are designed to be detachable, which facilitates installation, adjustment and later maintenance, effectively meeting the needs of different construction scenarios.

[0031] The horizontal splicing of the bracket 21 (along the X-axis direction, adapting to the wall length requirements) allows for the horizontal extension of the bracket 21 by connecting the adapter rod 22 and the first bolt 23 when the wall length needs to be adjusted according to the construction scenario. The specific operation is as follows:

[0032] Select several matching card holders 21 and align the ends of two adjacent card holders 21 (so that their trapezoidal transition grooves 5 are on the same straight line); insert the two ends of the adapter rod 22 into the transition grooves 5 of the two aligned card holders 21 respectively, ensuring that the adapter rod 22 fits against the inner wall of the transition groove 5; pass the first bolt 23 through the countersunk holes at both ends of the adapter rod 22 and tighten the first bolt 23 clockwise until the bolt end is pressed against the inner wall of the transition groove 5, thus completing the lateral fixation of the two card holders 21; repeat the above steps, and connect more card holders 21 in series to form a continuous lateral load-bearing track according to the actual wall length requirements. This track can directly embed a single row of composite sound insulation panels 1, and the cut card holders 21 can still be spliced ​​and reused in this way; through lateral splicing, the total length of the card holders 21 can be flexibly adapted to the wall length requirements of different construction scenarios, and the countersunk first bolt 23 avoids the interference of the protruding structure on the installation of the composite sound insulation panel 1 or the assembly of other components.

[0033] The longitudinal assembly of the card holder 21 (along the Y-axis direction, adapting to the wall height requirements) is achieved by using the engagement of the locking arm 24 and the locking claw 25 to realize the longitudinal symmetrical connection of the card holder 21 when the composite sound insulation board 1 needs to be stacked to meet the wall height requirements. The specific operation is as follows: Select several locking arms 24, fix the L-shaped locking claw 25 through the first mating port 6 of the locking arm 24, and ensure that the two ends of the locking claw 25 extend perpendicularly to the length direction of the locking arm 24; take two card holder groups (or a single card holder 21) that have been horizontally spliced, and place them symmetrically in opposite directions (so that the groove 4 of one card holder 21 faces upward and the groove 4 of the other faces downward); place the locking arm 24 equipped with the locking claw 25 between the two symmetrically opposite card holders 21, so that the two ends of the locking claw 25 are respectively movably inserted into the L-shaped groove 4 at the opposite end of the two card holders 21, while ensuring that the locking arm The second fitting port 7 of the 24 is aligned with the adapter groove 5 of the card seat 21; the adapter rod 22 is passed through the second fitting port 7 of the card arm 24 and inserted into the adapter groove 5 of the card seats 21 on both sides, and then tightened and fixed by the first bolt 23, so that the card arm 24 and the adapter rod 22 form a vertical cross structure, completing the longitudinal fixation of the two card seats 21; repeat the above steps, and stack more longitudinal card seats 21 according to the wall height requirements to form a multi-layer longitudinal load-bearing structure, each layer of the structure can be embedded with composite sound insulation board 1; the longitudinally assembled card seat 21 can stably support the multi-layer composite sound insulation board 1, and the vertical cross structure of the card arm 24 and the adapter rod 22 can distribute the force on the upper and lower ends of the composite sound insulation board 1, and prevent the board from shifting due to its own weight or external force. At the same time, the reverse symmetrical card seat layout is adapted to the double-sided installation requirements of the composite sound insulation board 1 (such as the alloy layer facing outward and the sound insulation material layer facing inward).

[0034] To further enhance the stability of the multi-layer longitudinal assembly structure and prevent the wall from loosening due to vibration or external forces, the connection of the longitudinal snap-fit ​​arms 24 is strengthened by connecting ribs 26. The specific operation is as follows: After the longitudinal multi-layer snap-fit ​​base 21 and snap-fit ​​arms 24 are assembled, select several connecting ribs 26; insert the two ends of the connecting ribs 26 into the slots 8 of two adjacent longitudinal snap-fit ​​arms 24 respectively, ensuring that the connecting ribs 26 and the inner wall of the slots 8 are tightly fitted; if higher stability is required, a small amount of structural adhesive can be applied to the mating area between the connecting ribs 26 and the slots 8 (not a necessary step, to be selected according to construction requirements); the connecting ribs 26 connect the longitudinally arranged snap-fit ​​arms 24 into a whole, forming a "longitudinal support frame", which effectively resists the transverse shear force of the wall and prevents the multi-layer composite sound insulation board 1 from tilting or falling off due to uneven stress.

[0035] like Figure 4 As shown, as a preferred embodiment, the connecting bridge structure 3 further includes a pair of support plates 31, a pair of sliders 32, and a pair of second bolts 33; one end of each pair of support plates 31 is L-shaped, and one end of each support plate 31 is respectively fitted into the sliding groove 4. One end of each pair of support plates 31 can be detachably inserted into the sliding groove 4 of the card holder 21, and the support plates 31 are located between the parallel card holders 21. The other ends of the pair of support plates 31 are respectively located on the upper and lower sides and are staggered and attached. The other end of one of the support plates 31 is provided with a pair of adjusting grooves 9, and the pair of sliders 32 are... Blocks 32 are movably embedded in the adjustment grooves 9, and a pair of second bolts 33 are movably inserted through the other end of another support plate 31, and the second bolts 33 are screwed into the sliders 32 respectively; the two card seats 21 are connected through the support plate 31 to realize the transverse splicing of the card seats 21 along the Z-axis direction, and the splicing spacing is adjusted by the sliders 32 and the second bolts 33, so that while the double-sided composite sound insulation board 1 wall is laid through the carding structure 2, there is also a space for spacing, effectively blocking noise, and multiple layers of other sound insulation materials can also be laid.

[0036] More specifically, the initial connection between the bridge structure 3 and the snap-fit ​​structure 2 (fixing the L-shaped end) requires the bridge structure 3 to connect two sets of parallel snap-fit ​​structures 2 (the two sets of snap-fit ​​structures 2 correspond to the two side frames of the double-sided soundproof wall respectively). The specific connection operation is as follows:

[0037] Select two sets of snap-fit ​​structures 2 that have been assembled horizontally / vertically, and place the two sets of snap-fit ​​structures 2 in parallel (the concave grooves of the two sets of structures' slots face each other, and are used to install the double-sided composite sound insulation panels 1 respectively).

[0038] Take a pair of trays 31, align the L-shaped end of each tray 31 with the L-shaped groove 4 of the corresponding slot 21 in the two sets of snap-fit ​​structures 2, and slowly insert it into the groove 4 until the L-shaped end of the tray 31 is completely fitted with the inner wall of the groove 4; ensure that the L-shaped end of the tray 31 is inserted in place without looseness or shaking, and that the non-L-shaped ends of the pair of trays 31 are at the same horizontal height, which facilitates subsequent staggered fitting; through the fitting connection between the L-shaped end and the groove 4, the bridge structure 3 can initially connect the two sets of parallel snap-fit ​​structures 2 in series, providing lateral support for the frame construction of the double-sided soundproof wall, while preventing the two sets of snap-fit ​​structures 2 from shifting relative to each other.

[0039] Wall thickness adjustment (by adjusting the distance between slider 32 and second bolt 33): Depending on the wall thickness requirements of the construction scenario (e.g., 50mm for standard sound insulation and 100mm for high sound insulation), the wall thickness can be adapted by adjusting the distance between the support plates 31. Specific operations are as follows:

[0040] Align the non-L-shaped ends of a pair of support plates 31 with each other (the support plate 31 with the adjustment groove 9 is on top, and the support plate 31 without the adjustment groove 9 is on the bottom, or vice versa, depending on the actual installation space); insert a pair of sliders 32 into the adjustment grooves 9 of the upper support plate 31, and slide the sliders 32 to the target position (the target position is determined according to the preset wall thickness: wall thickness = thickness of the two sets of snap-fit ​​structures 2's seat 21 + overlap spacing of the non-L-shaped ends of the support plates 31; the overlap spacing can be changed by moving the sliders 32, thereby adjusting the overall wall thickness); take a pair of second bolts 33, and pass each second bolt 33 through the lower support plate 31. Align the bolt through hole with the internal thread hole of the slider 32 in the upper adjustment groove 9, and turn the second bolt 33 clockwise until the bolt head is in contact with the surface of the lower support plate 31 and the slider 32 is firmly locked in the adjustment groove 9. At this time, the distance between the pair of support plates 31 is fixed, and the distance between the two sets of parallel snap-fit ​​structures 2 (i.e., the wall thickness) is also locked. By sliding the slider 32 in the adjustment groove 9, the wall thickness can be flexibly adjusted (the adjustment range is determined by the length of the adjustment groove 9, and the length of the adjustment groove 9 can be designed according to the requirements). There is no need to prefabricate wall frames of different thicknesses, which can be adapted to diverse construction scenarios (such as thick walls in factories and thin walls in residences).

[0041] Utilization of the mezzanine space and expansion of sound insulation performance: After the connecting bridge structure 3 and the two sets of snap-fit ​​structures 2 are assembled, a mezzanine space will be formed between the slots 21 of the two sets of snap-fit ​​structures 2 (i.e., the area enclosed by a pair of support plates 31). This space can be used to add sound insulation materials to further improve the sound insulation effect of the wall. The specific operation is as follows:

[0042] Confirm that the spacing of the connecting bridge structure 3 is locked, and that the card seats 21 of both sets of carding structures 2 are fitted with composite sound insulation panels 1 (the alloy layer of the composite sound insulation panel 1 faces outward, and the sound insulation material layer faces the interlayer space); according to the sound insulation requirements, lay additional sound insulation materials (such as sound insulation cotton, sound absorption panels, damping felt, etc.) into the interlayer space, ensuring that the sound insulation material fills the interlayer space without gaps or omissions during the laying process; if it is necessary to enhance the stability of the sound insulation material, a small number of support strips can be set in the interlayer space (the two ends of the support strips are fixed to the support plate 31) to prevent the sound insulation material from sinking or shifting due to its own weight; the design of the interlayer space makes the wall form a multi-layer sound insulation structure of "composite sound insulation panel 1, interlayer sound insulation material and composite sound insulation panel 1", which greatly improves the sound insulation effect through the reflection and absorption of sound waves between different materials; at the same time, the existence of the interlayer space can reduce the direct transmission of sound waves.

[0043] Furthermore, the relative width of one end of the support plate 31 can be adjusted by moving the slider 32 within the adjustment groove 9, thereby adjusting the spacing of the card holders 21 to fit the construction of walls of different thicknesses, meeting design requirements and achieving the construction of soundproof walls and improving sound insulation effects; the connecting bridge structure 3 is connected in series between the card holders 21, forming a sandwich space between the composite sound insulation boards 1 set by the card-connecting structure 2, which can lay multiple layers of sound insulation boards and achieve the control of sound insulation requirements.

[0044] Furthermore, the snap-fit ​​structure 2 can lay the composite sound insulation board 1 horizontally in a single layer, and can also lay multiple layers. It can be constructed with different materials and layers of sound insulation according to actual needs. The adapter rod 22 is used for horizontal series connection of the card seat 21 for horizontal splicing and assembly. The snap-fit ​​arm 24 and the card claw 25 are used for the card seat 21 to be set up symmetrically in opposite directions for the symmetrical laying of the wall.

[0045] Furthermore, to improve the practicality of the snap-fit ​​structure 2 and the bridge structure 3, both the snap-fit ​​base 21 and the bracket are made of metal and can be cut and installed.

[0046] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0047] The snap-fit ​​structure 2, through the cooperation of components such as the snap-fit ​​seat 21, the adapter rod 22, and the snap-fit ​​arm 24, completes the horizontal and vertical fixation of the composite sound insulation panel 1, thus building a basic framework for the wall.

[0048] Horizontal assembly: The adapter rod 22 is inserted into the trapezoidal adapter groove 5 of the adjacent card seat 21 and tightened by the first bolt 23, so that multiple card seats 21 are connected in series along the X-axis to form a horizontal bearing track for laying a single row of composite sound insulation board 1 to meet the needs of walls of different lengths.

[0049] Longitudinal assembly: Through the cooperation of the snap-fit ​​arm 24 and the L-shaped snap-fit ​​claw 25, the two ends of the snap-fit ​​claw 25 are embedded in the L-shaped sliding groove 4 of the card seat 21. At the same time, the snap-fit ​​arm 24 is fitted onto the adapter rod 22 through the second fitting port 7 to form a longitudinal support perpendicular to the transverse track, realizing the reverse symmetrical setting of the card seat 21. At this time, the card seat 21 is then horizontally fixed by the adapter rod 22, clamping the snap-fit ​​arm 24 to achieve the vertical symmetrical fixation of the card seat 21; composite sound insulation board 1 can be laid in the vertical direction to meet the wall height requirements;

[0050] If it is a height-layout, the connecting rib 26 is inserted into the slot 8 connected by the longitudinally arranged snap-fit ​​arms 24 to connect the upper and lower snap-fit ​​structures 2 into a whole, so as to prevent the composite sound insulation board 1 from loosening when under force and to ensure stable assembly.

[0051] When assembling a wall with a certain thickness:

[0052] The connecting bridge structure 3 connects the parallel snap-fit ​​structures 2 through the cooperation of the support plate 31, the slider 32 and the second bolt 33, so as to realize the adjustment of wall thickness and the optimization of sound insulation performance. The L-shaped end of the support plate 31 is inserted into the slide groove 4 of the card seat 21 to connect two sets of parallel snap-fit ​​structures 2, so that the overall frame forms a stable three-dimensional structure, which supports the symmetrical laying of double-sided composite sound insulation board 1, so that the outer alloy plate faces outward and the sound insulation material is located on the inside. The width of the wall can be adjusted by moving the slider 32 in the adjustment groove 9 to adjust the distance between the two ends of the support plate 31, and is tightened and fixed by the second bolt 33, so as to adjust the distance between the relatively parallel card seats 21 and thus adjust the wall thickness.

[0053] After the spacing is adjusted, a sandwich space is formed between the two sets of interlocking structures 2, that is, between the support plate 31 and the composite sound insulation board 1. Multiple layers of sound insulation materials (such as sound insulation cotton, sound absorption board, etc.) can be laid there. Combined with the sound insulation performance of the composite sound insulation board 1 itself, the overall sound insulation effect is improved through "multi-layer barrier".

[0054] Through the horizontal / vertical assembly of the snap-fit ​​structure 2 and the series adjustment of the connecting bridge structure 3, the overall wall can achieve: support the horizontal laying and vertical stacking of single / multi-layer composite sound insulation panels 1, and all components can be disassembled for easy installation, adjustment and later maintenance; no prefabrication is required, and the construction range can be adapted by cutting the components, and the cut materials can still be reused by splicing, reducing waste and prefabrication time; through the laying of multi-layer sound insulation materials in the interlayer space, combined with the adjustment of the wall thickness, the sound insulation needs of different scenarios can be met.

[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
