Description

Technical Field

[0001] This invention relates to the field of building technology, specifically to a multi-layer soundproof wall structure. Background Technology

[0002] In the field of building technology, soundproof walls are a key structure for improving the comfort of living or using buildings, and their design and construction have always been a focus of industry attention. At present, traditional soundproof walls mostly use wooden frames or metal fixed frames as support structures, and form walls by directly embedding or nailing soundproof panels into the frame.

[0003] In existing processing methods, frame structures are mostly prefabricated as a whole or fixed by on-site welding and nailing. Once their size and structure are determined, they are difficult to adjust. This fixed construction method results in poor flexibility of the walls during installation, and the frame components are difficult to reuse after disassembly, which does not meet the development needs of green buildings.

[0004] The existing equipment and structure have many shortcomings: First, the connection between the frame and the sound insulation panel is mostly rigid and fixed, which is cumbersome to operate; second, the splicing parts of the frame are simply designed, mostly using direct overlap or single bolt fixing, resulting in poor overall stability, especially in terms of seismic resistance and wind pressure resistance; third, the existing structure has a single way of supporting the sound insulation panel, which is difficult to adapt to the installation requirements of multi-layer sound insulation panels. If it is necessary to increase the thickness or number of sound insulation layers, the frame support structure needs to be redesigned, resulting in low versatility. Summary of the Invention

The pair of limiting slide rods are located on the upper and lower sides of the drive screw and are arranged parallel to each other. The bidirectional pressure plate is cross-shaped. The middle of the bidirectional pressure plate is movably screwed onto the drive screw, and the upper and lower ends of the bidirectional pressure plate are movably fitted onto the limiting slide rods. The left and right ends of the bidirectional pressure plate are located on the left and right sides of the flange.

[0009] Preferably, the side panel and the buckle panel are assembled into a square frame.

[0016] The multi-layer soundproof wall structure proposed in this invention has the following advantages compared to traditional wooden frame construction:

[0017] 1. The adapter component enhances assembly flexibility and adaptability: The adapter component adjusts the orientation of the first and second locking grooves by changing the side plate, which can flexibly realize the horizontal splicing, vertical splicing or right-angle transition of pipe beams. There is no need to customize special adapter parts, which greatly reduces the restrictions on construction space and size, adapts to diverse wall layout needs, and improves installation adaptability.

[0018] 2. Enhanced connection stability and convenience through the docking unit: The docking unit uses a simple groove and rod combination to achieve staggered locking. Through the precise fit of the first locking rod, the second locking rod and the locking groove, the side plate docking can be guaranteed to be stable and firm without complex connection structure, avoiding the problem of easy loosening in traditional connection methods; at the same time, the installation and operation are simple, reducing the reliance on professional tools and skills and improving construction efficiency.

[0019] 3. The support unit meets the requirements of multi-layer sound insulation and load-bearing adjustability: The support unit can effectively support the main body of multi-layer sound insulation panels. Through the adjustable method of bearing limit by the tube beam alone or in combination with the support unit, it can adapt to the installation requirements of sound insulation panels of different thicknesses and quantities. It not only ensures the stable bearing of the multi-layer structure, but also enhances the space for improving the sound insulation effect and improves the versatility and practicality of the structure.

[0020] 4. Overall structural optimization improves construction and maintenance efficiency: The modular splicing design of the frame structure, combined with the flexible adjustment and convenient connection of each component, makes the wall installation process more efficient, reduces complex processes such as on-site cutting and welding, and reduces material waste; at the same time, it is easy to disassemble, adjust or reuse later, which is in line with the concept of green building and reduces maintenance costs; and it can also fit the construction site, adjusting the size as the pipe beams or support plates are cut.

[0021] 5. Improve overall structural stability: The precise coordination of each component (such as the bidirectional pressure plate fixing of the adapter component and the staggered locking of the docking unit) reduces structural gaps and avoids the problem of loose connections in traditional walls; at the same time, the stable frame structure enhances the wall's earthquake resistance and wind pressure resistance, improving overall safety.

[0030] 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.

[0031] Please see Figures 1-7 The present invention provides a technical solution: a multi-layer soundproof wall structure, comprising a plurality of soundproof panel bodies 1, wherein a frame structure is fitted on the outer side of the plurality of soundproof panel bodies 1, the frame structure can be spliced ​​and assembled relative to each other, and the soundproof panel bodies 1 are limited by the frame structure and spliced ​​to form a wall.

[0032] like Figure 1 , Figure 2 and Figure 7As shown, as a preferred embodiment, the frame structure includes several pipe beams 2, several transition components 3, several docking units 4, and several supporting units 5; the pipe beams 2 are all hollow tubes, and the two ends of the pipe beams 2 are respectively connected to each other by several transition components 3. The transition components 3 are spliced ​​together by several docking units 4, and the supporting units 5 are detachably mounted on the pipe beams 2; the pipe beams 2 are assembled into a straight transition, an L-shaped support transition, or a T-shaped transition by the transition components 3, and the transition components 3 are spliced ​​together by the docking units 4. The supporting units 5 can limit the position of the sound insulation panel body 1. The sound insulation panel body 1 is positioned by the pipe beams 2 or supported by the pipe beams 2 and the supporting units 5, and is used to support the sound insulation panel body 1 in various ways.

[0033] More specifically, according to the wall size requirements, the pipe beam 2 is connected to the basic frame unit through the adapter component 3, such as: straight, L-shaped or T-shaped; multiple basic frame units are spliced ​​together using the docking unit 4 to form an overall frame structure; if it is necessary to install the multi-layer sound insulation panel body 1, the support unit 5 is installed at the corresponding position on the pipe beam 2; the sound insulation panel body 1 is placed through the limiting structure of the pipe beam 2 or the cooperation structure between the pipe beam 2 and the support unit 5 to complete the wall assembly.

[0034] like Figure 3 and Figure 4As shown, in a preferred embodiment, the adapter assembly 3 includes a pair of snap-on plates 31, a pair of side plates 32, a pair of retaining edges 33, a drive screw 34, a pair of limiting slide rods 35, and a bidirectional pressure plate 36. The pair of snap-on plates 31 are both square plates, and the pair of side plates 32 are the same size as the snap-on plates 31. The pair of side plates 32 are detachably mounted between the two ends of the snap-on plates 31 by first bolts 37, with the first bolts 37 countersunk at the four corners of the side plates 32. The side plates 32 and snap-on plates 31 are assembled into a square frame. The upper and lower side walls of the pair of side plates 32 are each provided with a cross-shaped first locking groove 6 that penetrates through them. The pair of side plates 32 are positioned on the left and right sides... Each sidewall has a second locking groove 7 that passes through it, and the second locking groove 7 is perpendicular to and passes through the first locking groove 6. A pair of retaining edges 33 are symmetrically arranged in the middle of one of the side plates 32 and are located on opposite sidewalls of the side plates 32. The retaining edges 33 are located between the buckle plates 31. One end of the driving screw 34 is movably embedded in the middle of one of the side plates 32, and both ends of the driving screw 34 are provided with hexagonal nuts. One end of the driving screw 34 moves through the retaining edges 33, and the other end of the driving screw 34 is detachably embedded in the middle of the other side plate 32. The driving screw 34 cannot be detached from one of the side plates 32. A pair of limiting slide rods 35 One end is fixedly installed on the side wall of one of the side plates 32 and located between the retaining edges 33. A pair of limiting slide rods 35 are respectively located on the upper and lower sides of the drive screw 34 and are arranged parallel to each other. The bidirectional pressure plate 36 is cross-shaped. The middle part of the bidirectional pressure plate 36 is movably screwed onto the drive screw 34, and the upper and lower ends of the bidirectional pressure plate 36 are respectively movably fitted onto the limiting slide rods 35. The left and right ends of the bidirectional pressure plate 36 are respectively located on the left and right sides of the retaining edge 33. The side plate 32 is fastened to the two ends of the buckle plate 31 by the first bolt 37, and the pipe beam 2 can be inserted between the buckle plate 31 and the side plate 32. By rotating the drive screw 34, the bidirectional pressure plate 36 is forced to move. 6. The force is applied to the moving limit slide bar 35 to press and fix the pipe beam 2. Since the side plate 32 is detachable by the first bolt 37 and the drive screw 34 can rotate inside the side plate 32, the side plate 32 can adjust the orientation of the first locking groove 6 and the second locking groove 7 as needed, or position the first locking groove 6 and the second locking groove 7 according to the actual installation requirements. Alternatively, the side wall of the buckle plate 31 can be provided with the first locking groove 6 and the second locking groove 7 to fit together, increasing the installation orientation. The two ends of the pipe beam 2 are respectively inserted between the buckle plates 31, and the pipe beam 2 is limited by the stop 33 for design installation limitation. The pipe beam 2 is clamped and fixed by the bidirectional pressure plate 36 for design installation fixation.

[0035] More specifically, the adapter assembly 3, through the coordinated action of its various components, enables the limiting, fixing, and multi-angle steering of the tube beam 2. Its specific working principle and functions are as follows:

[0036] When connecting the tube beam 2 to the adapter assembly 3, insert one end of the tube beam 2 into the open end of the square frame until the end of the tube beam 2 abuts against the retaining edge 33. At this time, the retaining edge 33 provides initial restraint for the tube beam 2 to prevent over-insertion. Then, insert an Allen wrench into the Allen nut at one end of the drive screw 34 and rotate the drive screw 34 clockwise. Since the drive screw 34 is connected to the bidirectional pressure plate 36 by threads, and the bidirectional pressure plate 36 is guided by the limiting slide rod 35, the rotation of the drive screw 34 will be converted into the linear movement of the bidirectional pressure plate 36 along the limiting slide rod 35. As the bidirectional pressure plate 36 moves toward the tube beam 2, the pressing ends at its left and right ends will gradually fit against the side wall of the tube beam 2. Continue to rotate the drive screw 34 until the bidirectional pressure plate 36 tightly clamps the tube beam 2 in the frame, thus fixing the tube beam 2, replacing the traditional welding or nailing fixing method, and it can be disassembled and reused.

[0037] When it is necessary to achieve transverse splicing, longitudinal splicing, or right-angle transition of pipe beam 2, there is no need to customize special transition parts. It can be achieved simply by adjusting the orientation of the side plate 32: First, use a wrench to loosen the first bolt 37 to release the fixing relationship between the side plate 32 and the buckle plate 31; according to the required splicing direction (such as transverse, longitudinal, or right angle), rotate the side plate 32 to adjust the orientation of the first locking groove 6 and the second locking groove 7 on the side plate 32 so that the direction of the locking groove matches the axial direction of the pipe beam 2 to be spliced; after the adjustment is completed, tighten the first bolt 37 again to fix the side plate 32 to the buckle plate 31; if it is necessary to further increase the installation orientation, grooves that match the first locking groove 6 and the second locking groove 7 can be opened on the side wall of the buckle plate 31, so that the buckle plate 31 can also be used as a locking groove carrier, meeting more diverse splicing needs and greatly reducing the restrictions on construction space and size.

[0038] In actual construction sites, if the length of pipe beam 2 does not match the preset size, pipe beam 2 can be directly cut and adjusted to the required length. After that, the cut pipe beam 2 is inserted into the square frame of the adapter component 3, limited by the stop 33 and then clamped and fixed by the bidirectional pressure plate 36. There is no need to redesign or replace the adapter component 3, which fully meets the actual needs of the construction site and improves the adaptability of installation and construction efficiency.

[0039] like Figure 5As shown, in a preferred embodiment, the docking unit 4 includes a first locking rod 41, a second locking rod 42, and several second bolts 43. The first locking rod 41 is detachably inserted into the second locking groove 7, and the first locking rod 41 has a latch 8 near both ends that fits into the first locking groove 6. The two ends of the second locking rod 42 are detachably inserted into the first locking groove 6 of two side plates 32, and the second locking rod 42 moves through the second locking groove 7 and the latch 8 respectively. Several second bolts 43 are countersunk and embedded in the ends of the first locking rod 41 and the second locking rod 42, and the second bolts 43 are screwed into the first locking groove 6 and the second locking groove 7 respectively. By inserting the first locking rod 41 into the second locking groove 7 and then inserting the second locking rod 42 into the first locking groove 6, the first locking rod 41 and the second locking rod 42 are perpendicularly intersected and fixed by the second bolts 43, so that the first locking rod 41 and the second locking rod 42 are staggered in different side plates 32, and the docking combination of the side plates 32 is stable.

[0040] The assembly of docking unit 4 is based on the pre-assembled adapter component 3 and is carried out in accordance with the steps of "first cross-clamping, then fixing" to ensure that the side plates 32 of the two adapter components 3 can be stably spliced. The specific process is as follows:

[0041] Positioning of adapter component 3: According to the design dimensions and splicing requirements of the wall frame, place the two adapter components 3 to be spliced ​​in the preset position, so that the side plates 32 of the two adapter components 3 are close to each other and parallel, ensuring that the second locking groove 7 of one side plate 32 and the first locking groove 6 of the other side plate 32 are in the same vertical plane (that is, the axis of the second locking groove 7 intersects the axis of the first locking groove 6 perpendicularly), laying the foundation for the cross-fitting of the first locking rod 41 and the second locking rod 42.

[0042] First locking rod 41 insertion: Take the first locking rod 41 and align it horizontally with the second locking groove 7 of one of the side plates 32. Slowly insert it into the second locking groove 7 until both ends of the first locking rod 41 are flush with the two side walls of the side plate 32. During the insertion process, ensure that the latch 8 on the first locking rod 41 is facing upward (or towards the first locking groove 6 of the other side plate 32), and that the position of the latch 8 is completely aligned with the position of the first locking groove 6 of the other side plate 32 to avoid the second locking rod 42 being unable to pass through.

[0043] The second locking rod 42 crosses through: Take the second locking rod 42 and align it vertically (perpendicular to the first locking rod 41) with the first locking groove 6 of the other side plate 32, and slowly insert it into the first locking groove 6; continue to push the second locking rod 42 so that it passes through the first locking groove 6 of the side plate 32, the second locking groove 7 of the first side plate 32 and the latch 8 of the first locking rod 41 in sequence, until both ends of the second locking rod 42 are flush with the outer walls of the two side plates 32 respectively. At this time, the first locking rod 41 and the second locking rod 42 form a "cross" structure, which initially locks the two side plates 32 together.

[0044] Fixed locking: Insert the second bolts 43 into both ends of the first locking rod 41, and tighten the second bolts 43 clockwise with an Allen wrench so that the second bolts 43 are screwed into the preset threaded holes in the second locking groove 7, until the first locking rod 41 and the side plate 32 are tightly fitted and there is no looseness; then insert the remaining second bolts 43 into both ends of the second locking rod 42, and tighten them until the second locking rod 42 and both side plates 32 are tightly fitted, completing the assembly of the docking unit 4 and realizing the stable splicing of the two adapter components 3.

[0045] The docking unit 4 solves the problem of traditional frame splicing relying solely on single overlap or bolt fixation, which is prone to loosening, by "the vertical cross-locking of the first locking rod 41 and the second locking rod 42 and the rigid fixation of the second bolt 43".

[0046] Since the assembly of the docking unit 4 only relies on the first locking groove 6 and the second locking groove 7 pre-set on the side plate 32, there is no need to open other mounting holes on the adapter component 3. Therefore, it can be adapted to various directional splicing scenarios of the adapter component 3, such as horizontal straight splicing, vertical stacking splicing, and right-angle directional splicing. Only by adjusting the relative position of the two adapter components 3 according to the splicing direction to ensure that the locking grooves are aligned, a stable connection can be achieved through the same docking unit 4, reducing the customization requirements of special splicing parts and reducing construction costs and operational complexity.

[0047] like Figure 6 As shown, in a preferred embodiment, the support unit 5 includes a support frame 51, a third bolt 52, and a support plate 53. The support frame 51 is a frame structure, and support openings 54 are symmetrically arranged at both ends of the support frame 51. The support frame 51 is detachably mounted on the pipe beam 2. The third bolt 52 is countersunk and embedded in the front and rear side walls of the support frame 51, and the third bolt 52 is tightened against the side wall of the pipe beam 2. The support plate 53 is detachably arranged between the support plates 53, and the support plate 53 is located at the support opening 54 and fits. The support frame 51 is mounted on the pipe beam 2 and tightened by the third bolt 52. The support plate 53 is embedded in the support opening 54 of the support frame 51 to support the multi-layer sound insulation board body 1.

[0048] The support unit 5 constructs an adjustable multi-layer load-bearing structure through the "detachable fixing of the support frame 51 and the tube beam 2 and the precise fitting of the support plate 53 and the support opening 54", which solves the problem of the traditional frame having "a single load-bearing method and difficulty in adapting to multi-layer sound insulation panels".

[0049] The support frame 51 is fixed by tightening the tube beam 2 with the third bolt 52. Compared with the traditional welding or nailing method, it does not require damage to the structure of the tube beam 2 and can be flexibly adjusted in height according to the installation requirements of the sound insulation board. The support frame 51 can be moved by loosening the third bolt 52, which can adapt to the multi-layer combination requirements of sound insulation boards of different thicknesses, greatly improves the construction flexibility and reduces the scrapping of parts due to dimensional deviations.

[0050] The support plate 53 fits into the U-shaped groove of the support bracket 51 support opening 54 through its edge, forming an "embedded" load-bearing structure; the side wall of the support opening 54 can limit the lateral displacement of the support plate 53, preventing the support plate 53 from sliding when bearing the weight of the sound insulation board or being impacted by external forces; at the same time, the frame structure of the support bracket 51 can distribute the load transmitted by the support plate 53 to the tube beam 2, ensuring uniform overall load-bearing, preventing structural deformation caused by local stress concentration, and ensuring the installation stability of the multi-layer sound insulation board.

[0051] When only a single layer of sound insulation board is needed, the support unit 5 can be omitted, and the sound insulation board can be directly installed by limiting the pipe beam 2. When it is necessary to improve the sound insulation effect and increase the number of sound insulation board layers, a multi-layer load-bearing structure can be quickly constructed by adding support unit 5 without redesigning or replacing the main frame. In addition, the support plate 53 can be cut and adjusted in length according to the needs of the construction site to adapt to the layout of walls of different widths, further improving the adaptability of the structure to different scenarios and reducing customization costs.

[0052] 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.

[0053] A pair of square buckle plates 31 and a pair of side plates 32 of the same size are connected by first bolts 37 at the four corners to form a square frame; the upper and lower side walls of the side plate 32 are provided with cross-shaped first locking grooves 6, and the left and right side walls are provided with second locking grooves 7 that are perpendicular to the first locking grooves 6, reserving interfaces for subsequent splicing.

[0054] Insert both ends of the hollow tube beam 2 into the frame formed by the buckle plate 31 and the side plate 32. The tube beam 2 is initially limited by the symmetrical retaining edge 33 in the middle of the side plate 32. Rotate the drive screw 34, which has hexagonal nuts at both ends, to drive the cross-shaped bidirectional pressure plate 36 to move along the limiting slide rods 35 on the upper and lower sides of the drive screw 34, so that the left and right ends of the bidirectional pressure plate 36 clamp the tube beam 2, and complete the docking and fixing of the tube beam 2.

[0055] When multi-angle conversion: the installation orientation of the first locking groove 6 and the second locking groove 7 of the side plate 32 is adjusted by removing the first bolt 37, and then the two sets of conversion components 3 are assembled relative to each other by the docking unit 4; the first locking rod 41 is inserted into the second locking groove 7 and the two ends of the second locking rod 42 are respectively inserted into the first locking groove 6 of the side plate 32 of the two conversion components 3, and the second locking rod 42 passes through the bayonet 8 of the first locking rod 41 to achieve the perpendicular intersection of the first locking rod 41 and the second locking rod 42, thereby locking relative to each other, and finally fixed by the second bolt 43 to achieve the docking assembly of the conversion components 3;

[0056] By assembling the adapter component 3, the openings of the buckle plate 31 and the side plate 32 are made to be in the same or different directions, thereby realizing the straight, L-shaped or T-shaped adapter of the pipe beam 2 to form a basic frame;

[0057] By using countersunk second bolts 43, the ends of the first locking rod 41 and the second locking rod 42 are respectively tightened into the corresponding first locking groove 6 and the second locking groove 7, so that multiple adapter components 3 are stably spliced ​​together, expanding the overall structure of the frame; at this time, the sound insulation panel body 1 can be set between the pipe beams 2 for limiting and bearing.

[0058] Alternatively, the support unit 5 can be set on the pipe beam 2 to cooperate in bearing the multi-layer sound insulation board body 1;

[0059] The support frame 51 with the support opening 54 is fitted into the preset position of the pipe beam 2. The support frame 51 is tightened against the side wall of the pipe beam 2 by the countersunk third bolts 52 on the front and rear side walls of the support frame 51, so as to achieve the detachable fixation of the support frame 51. The edge of the support plate 53 is embedded into the support opening 54 of the support frame 51 to form a horizontal bearing surface, and cooperates with the pipe beam 2 to provide support for the multi-layer sound insulation board body 1.

[0060] Based on the construction site and the dimensions of the sound insulation panel body 1, the pipe beam 2 and the support plate 53 can be directly cut and adjusted to fit the wall dimensions and the dimensions of the sound insulation panel body 1 at the construction site.

[0061] In summary, this structure achieves flexible assembly, stable load-bearing capacity, and multi-layer sound insulation through the process of "connecting pipe beam 2 with adapter component 3, extending frame with docking unit 4, supporting unit 5 for auxiliary load bearing, and splicing sound insulation panel body 1 into a wall".

[0062] 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.
