Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, specifically to a sound-insulating integrated wall panel with an assembled structure. Background Technology

[0002] Currently available interior partitions for office buildings have several problems with their acoustic requirements, failing to meet ideal sound insulation standards. Traditional methods, such as ALC panels and autoclaved aerated concrete blocks, involve cumbersome construction procedures, primarily wet work, resulting in a dirty and unsanitary work environment. Their installation efficiency is low, averaging only 20 square meters per day, and the wall thickness is typically 240 mm, occupying a significant amount of indoor floor space while providing only 45 to 48 decibels of sound insulation. On the other hand, while lightweight steel frame walls are thinner, their sound insulation is only 40 to 45 decibels, and their construction is similarly cumbersome, with installation efficiency also limited to around 30 square meters per day.

[0003] Furthermore, current modular wall systems used in office settings only soundproof the large visible wall surfaces, leaving concealed spaces such as the interior of ceilings and raised floors unsealed, allowing sound to propagate through these cavities. Additionally, the framing of integrated wall panels on the market is often inadequately treated, potentially contributing to vibration transmission. Considering these issues, existing high-sound-insulation wall panel products fall short of achieving ideal overall soundproofing performance, resulting in a poor office experience for customers. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated soundproof wall panel with an assembled structure to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated sound insulation wall panel with an assembled structure, comprising a keel frame and a composite damping plate fixed to the keel frame; The keel frame includes two vertical support members and two horizontal support members. The vertical support members and the horizontal support members are alternately connected to form a frame structure, and a middle support member is provided between the two horizontal support members. The vertical support, the horizontal support, and the central support all use thermally broken aluminum keel; An I-beam aluminum plate is installed on the vertical support member on one side of the keel frame, and adjacent integrated wall panels are fastened together by the I-beam aluminum plate.

[0006] Furthermore, the thermally broken aluminum keel has through holes along its length, and the through holes are filled with sound-insulating material.

[0007] Furthermore, the composite damping plate includes a base composite plate and an exterior composite plate. The base composite plate is disposed inside the keel frame, and the exterior composite plate covers the outside of the keel frame and the base composite plate. Sound insulation material is filled between the base composite plates on both sides and the keel frame.

[0008] Furthermore, the middle support is provided with a first mounting hook, and the outer composite panel is provided with a second hook, the second hook being engaged with the first mounting hook; The vertical support and the horizontal support are both symmetrically provided with second mounting hooks on the thermally broken aluminum keel. The second mounting hooks form a groove with the thermally broken aluminum keel for installing I-beams.

[0009] Furthermore, the thermally broken aluminum keel of the vertical support member is provided with a plurality of second positioning hooks, the second positioning hooks facing the horizontal support member; the thermally broken aluminum keel of the horizontal support member is provided with a plurality of second positioning hooks, the second positioning hooks facing the inner side of the keel frame; the thermally broken aluminum keel of the middle support member is symmetrically provided with a plurality of first positioning hooks.

[0010] Furthermore, the I-beam includes an I-beam portion and two snap-fit ​​portions, which are symmetrically fixed at both ends of the I-beam portion. During installation, the ends of the I-beam portion are used to snap-fit ​​into the slots.

[0011] Furthermore, a plastic strip is provided between the vertical support member and the I-beam aluminum.

[0012] Furthermore, the thermally broken aluminum keel includes two sub-keels and two thermal break strips. The two sub-keels are placed side by side with a gap between them. The thermal break strips are arranged along the length of the sub-keels, and both sides of the thermal break strips are fixedly connected to the two sub-keels respectively. The two thermal break strips are arranged side by side.

[0013] Furthermore, it also includes L-shaped plate-shaped connectors made of aluminum alloy, one end of which is used to fix it to the top or bottom plate of the floor, and the other end is used to insert into the horizontal support of the integrated wall panel to fix the integrated wall panel in a predetermined position.

[0014] Furthermore, the cross-sectional shape of the thermally broken aluminum keel used in the vertical support and the horizontal support is the same, but different from the cross-sectional shape of the thermally broken aluminum keel used in the middle support.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention constructs a multi-layered acoustic impedance structure consisting of "composite damping plate + air layer + composite damping plate + rock wool + composite damping plate + air layer + composite damping plate" by setting multiple rows of composite damping plates on both sides of the keel frame. The keel frame is made of thermally broken aluminum keel, effectively blocking vibration transmission between keels and improving sound insulation by 8-10 dB. Sealing treatment inside the ceiling and floor creates a closed sound insulation loop throughout the building space, further enhancing sound insulation. The integrated wall panels have a total thickness of only 125 mm, achieving an overall sound insulation of over 58 decibels, achieving both high sound insulation and thinness. By completing the keel frame fabrication and base composite panel installation in the factory, on-site construction only requires left-right splicing using I-beam aluminum, eliminating the need for on-site cutting, significantly improving installation efficiency and reducing construction waste.

[0018] 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.

[0019] See Figures 1-14 .

[0020] This invention provides an integrated soundproof wall panel with an assembled structure, a keel frame 2, and a composite damping plate fixed to the keel frame 2; The keel frame 2 includes two vertical support members 6 and two horizontal support members 7. The vertical support members 6 and the horizontal support members 7 are alternately connected to form a frame structure, and a middle support member 8 is provided between the two horizontal support members 7. The vertical support 6, the horizontal support 7, and the middle support 8 are all made of thermally broken aluminum keel; An I-beam aluminum 4 is installed on the vertical support member 6 on one side of the keel frame 2, and adjacent integrated wall panels 1 are fastened together by the I-beam aluminum 4.

[0021] The integrated wall panel includes a keel frame 2 and a composite damping plate fixed on the keel frame 2. On the construction site, multiple integrated wall panels are spliced ​​together to form an inner partition wall, thus completing the construction.

[0022] To improve sound insulation, three measures were taken: 1. The aluminum keel used in the construction of the keel frame 2 is all thermally broken aluminum keel, which effectively blocks the vibration between the keels and can improve the sound insulation by 8-10 dB. 2. The integrated wall panel has been sealed in both the ceiling 17 and the floor, thus forming a closed sound insulation loop throughout the entire building space, further improving the sound insulation effect; 3. By arranging multiple rows of composite damping plates on both sides of the keel frame 2, a multi-layer acoustic impedance structure of "composite damping plate + air layer + composite damping plate + rock wool + composite damping plate + air layer + composite damping plate" is constructed, and this impedance structure is provided with 4 rows of composite damping plates in total; the overall sound insulation capacity of the integrated wall panel is significantly improved. The total thickness of the integrated wall panel is 125 mm, and the overall sound insulation amount can reach 58 decibels or more.

[0023] In one embodiment, Figure 2-3 , the keel frame 2 includes two vertical support members 6 and two horizontal support members 7, the vertical support members 6 and the horizontal support members 7 are connected alternately to form a "loop-shaped" frame structure; zero or more intermediate support members 8 are arranged between the two horizontal support members 7; specifically, whether to arrange the intermediate support members 8 and the number of the intermediate support members to be arranged are determined according to the spacing between the two horizontal support members 7.

[0024] In one embodiment, the vertical support members 6, the horizontal support members 7 and the intermediate support members 8 all adopt broken bridge aluminum keels.

[0025] In order to install the composite damping plates on the keel frame 2 more reasonably and quickly, and control the thickness of the manufactured inner partition wall, the keel frame 2 is improved; after the improvement, the keel frame 2 is mainly made by splicing two types of broken bridge aluminum keels; Figure 12 and Figure 13 , the differences between the two types of broken bridge aluminum keels are as follows: 1. The cross-sectional shapes are different, the first type of broken bridge aluminum keel is symmetrically provided with first assembly hooks 11, and the second type of broken bridge aluminum keel is symmetrically provided with second assembly hooks 12; 2. The number of positioning hooks arranged thereon is different, the first type of broken bridge aluminum keel is symmetrically provided with two positioning hooks, and the second type is provided with a positioning hook only on one side; cutting is carried out according to the drawing design during manufacturing; Two specifications of composite damping plates are adopted, Figure 1 , Figure 5 and Figure 8 , one is a base composite plate 31; the other is an exterior decorative composite plate 32; the base composite plate 31 is shorter than the exterior decorative composite plate 32, and the base composite plate 31 is arranged inside the keel frame 2 after being spliced up and down; the exterior decorative composite plate 32 is used to integrally cover the outer sides of the keel frame 2 and the base composite plate 31, so as to perform sound insulation and beautification functions.

[0026] In one embodiment, the broken bridge aluminum keel of the vertical support member 6 is a first broken bridge aluminum keel 101, which is used for splicing with the front and rear integrated wall panels, and the splicing position needs to be fitted with an I-shaped aluminum 4 to obtain an inner partition wall; The broken bridge aluminum keel of the horizontal support member 7 is a second broken bridge aluminum keel 102, which is used for adaptive installation at the end of the vertical support member 6, so as to be spliced with the top plate 16 or the top plate 16 of the floor at the construction site; The thermally broken aluminum keel of the middle support member 8 is the third thermally broken aluminum keel 103, which is used to adapt and install in the middle of the vertical support member 6 to connect the two adjacent composite damping plates, and also to enhance the strength of the keel frame 2. Figure 12 Therefore, the cross-sections of the first thermally broken aluminum keel 101 and the second thermally broken aluminum keel 102 are the same (using the second type of thermally broken aluminum keel), and are different from the cross-section of the third thermally broken aluminum keel 103 (using the first type of thermally broken aluminum keel). Specifically, the third thermally broken aluminum keel 103 is symmetrically provided with first positioning hooks 13 on both sides, with a total of 4 hooks; the first thermally broken aluminum keel 101 and the second thermally broken aluminum keel 102 are each provided with second positioning hooks 14 on only one side, with a total of 2 hooks; during manufacturing, the second positioning hooks 14 on the first thermally broken aluminum keel 101 face the transverse support 7, and the second positioning hooks 14 on the second thermally broken aluminum keel 102 face the inner side of the keel frame 2 on which they are located.

[0027] The assembly process consists of two parts: factory assembly and on-site installation. The first part involves the fabrication of the integrated sound-insulating wall panels in the factory. The specific steps are as follows: S1. Fabrication of the keel frame 2: Complete the mold opening for two types of thermally broken aluminum keels in the factory. Connect the left vertical support 6 to the bottom and horizontal support 7 using angle brackets and self-tapping screws; connect the four middle support 8 to the left vertical support 6 using self-tapping screws; connect the left vertical support 6 to the top horizontal support 7 using angle brackets and self-tapping screws; connect the right vertical support 6 to the top and bottom horizontal support 7 using angle brackets and self-tapping screws. S2. Install the I-beam aluminum 4: Install the I-beam aluminum 4 on the vertical support 6 on the right side, that is, install the I-beam aluminum 4 on the right side of the keel frame 2 and fix it with self-tapping screws. The I-beam aluminum 4 is used for splicing the integrated wall panels on the left and right sides during on-site construction. S3. Install the base composite panel 31: Fill the interior of the keel frame 2 with rock wool; install the base composite panels 31 on both sides one by one, and embed one base composite panel 31 between each of the two adjacent thermally broken aluminum keels. After embedding, the top and bottom of the base composite panel 31 abut against the thermally broken aluminum keels at both ends respectively; insert the first hook 311 on the base composite panel 31 into the positioning hook on the thermally broken aluminum keel, and then connect it to the thermally broken aluminum keel with self-tapping screws. After installing all the base composite panels 31, an integrated wall panel is obtained; wherein, the height of the base composite panel 31 is adapted to the spacing between the two adjacent thermally broken aluminum keels.

[0028] In one embodiment, the connector 18 is an L-shaped plate made of aluminum alloy. One end of it is used to fix it to the top plate 16 or bottom plate 15 of the floor, and the other end is used to insert it into the horizontal support member 7 of the integrated wall panel.

[0029] The second part outlines the installation process that needs to be completed on-site: F1. Erect the integrated wall panel and place it in the designated position; F2. Use expansion bolts to fix the connector 18 to the base plate 15 (structural ground) and the top plate 16 (structural top surface) on both sides of the integrated wall panel, and fix the pad 19 to the connector 18 so that the horizontal support 7 of the integrated wall panel is locked between the connectors 18 on both sides; the second assembly hook 12 of the horizontal support 7 is locked between the connector 18 and the pad 19. F3. Hang the exterior composite panel 32 on the integrated wall panel via the second hook 111 thereon. Specifically, the second hook 111 is connected to the first assembly hook 11 on the middle support member 8. F5. Similarly, repeat steps F1-F4 to install the remaining integrated wall panels and exterior composite panels 32. The integrated wall panels on the left and right sides are connected by I-beam aluminum 4. Plastic strips 24 are installed between the vertical support 6 and the I-beam aluminum 4. Figure 11 A decorative strip 23 with a visible frame is attached to the end of the I-beam aluminum 4 (one end of the decorative strip 23 is attached to the attachment part 41, and the other end is flush with the outer surface of the exterior composite panel 32), which enhances the sound insulation performance of the wall. The decorative strip 23 with a visible frame can fill the gap between two adjacent composite damping panels on the left and right.

[0030] F6. Install the top ceiling 17 and the bottom floor 171; F7. The decorative line 20 consists of a cover plate 21 and a snap plate 22. When the cover plate 21 is installed, the opening of the cover plate 21 faces outward. It is fixed to the thermally broken aluminum keel after passing through the exterior composite panel 32 with self-tapping screws. The snap plate 22 is snapped onto the cover plate 21 to cover the end of the self-tapping screw and play an aesthetic role. A total of 4 decorative lines 20 are configured on an integrated wall panel, that is, two are configured on an exterior composite panel 32, one at the top of the exterior composite panel 32 and one at the bottom of the exterior composite panel 32.

[0031] In one embodiment, the thermally broken aluminum keel itself has through holes 9 along its length, making the interior of the modular frame hollow (cavity structure). Part of the sound insulation material fills the through holes 9 inside the aluminum keel; another part of the sound insulation material fills the closed space formed by the modular frame and the composite damping plate. The sound insulation material is rock wool or glass wool, or a mixture of rock wool and glass wool.

[0032] In one embodiment, Figure 14The I-beam aluminum 4 includes an I-beam portion 40 and two snap-fit ​​portions 41. The two snap-fit ​​portions 41 are symmetrically fixed at both ends of the I-beam portion 40. The ends of the I-beam portion 40 are used to snap-fit ​​with the slot 141. The snap-fit ​​portions 41 are used to snap-fit ​​the decorative strip 23 of the exposed frame. The I-beam 40 is placed horizontally, and the two ends of one side of the I-beam 40 are snapped to the vertical support 6 on the right side of the first integrated wall panel 1. The middle part of the I-beam 40 is attached to the vertical support 6 and then fixedly connected by self-tapping screws. The two ends of the other side of the I-beam 40 are snapped to the horizontal support 7 on the left side of the second integrated wall panel 1, thus completing the connection of the two integrated wall panels 1.

[0033] Figure 12 and 13 The thermal break aluminum keel consists of two sub-keels and two thermal break strips. The thermal break strips are made of polyamide and fiberglass composite. During manufacturing, the two sub-keels are placed side by side with a gap between them. The thermal break strips are laid along the length of the sub-keels (the two are of equal length), and both sides of the thermal break strips are fixedly connected to the pair of sub-keels. The two thermal break strips are placed side by side and are perpendicular to the sub-keels.

[0034] The thermal break strip is made of polyamide and glass fiber composite; the polyamide is such as polyamide 66, also known as PA66 or glass fiber reinforced polyamide 66; the glass fiber thermal break strip is such as the HK11 model thermal break strip; the addition of glass fiber (GF) to polyamide 66 (PA66, i.e., nylon 66) results in a qualitative leap in its mechanical strength; it is not a simple mixture, but rather the glass fiber forms a three-dimensional network in the PA66 matrix, acting like "steel bars" to bear and transfer loads, thereby significantly improving the overall strength of the material. The connection between the thermal break strip and the aluminum keel is a high-strength adhesive, which can then fix the aluminum keel on both sides and the thermal break strip in the middle into one piece.

[0035] The cross-sectional shapes of the first thermally broken aluminum keel 101 and the second thermally broken aluminum keel 102 are adapted to the I-beam aluminum 4, so that the two can be snapped together and then fixed with self-tapping screws.

[0036] The base composite board 31 includes a base board, a sound insulation rubber pad, and a base board, which are pressed together in sequence; The exterior composite panel 32 includes a baseboard, a sound-insulating rubber pad, and a decorative panel, which are pressed together in sequence.

[0037] In existing technologies, grooves are typically set at the bottom of the upper integrated wall panel, and protrusions are set at the top of the lower integrated wall panel. The panels are joined by interlocking the grooves and protrusions. To further reinforce the joints, connecting plates are wrapped around the outer surface of the joints and then secured with bolts. To ensure the flatness and strength of the wall after assembly and to facilitate subsequent wall beautification, gaps need to be pre-cut in the integrated wall panels during manufacturing so that the connecting plates can fit perfectly into them. However, this increases the number of connecting parts required during assembly, significantly increasing the difficulty and procedures involved in manufacturing and extending the production time.

[0038] In this case, the structure of the aluminum keel itself is improved. Depending on the position of the aluminum keel, the first positioning hook 13 or the second positioning hook 14 is used in conjunction, eliminating the need for grooving on the composite damping plate. Both the aluminum keel and the composite damping plate are manufactured in-house using molds. Because the first thermally broken aluminum keel 101 and the second thermally broken aluminum keel 102 have the same structure (same cross-sectional shape) and both have the second positioning hook 14 on only one side, two integrated wall panels can be spliced ​​together vertically using I-beam aluminum 4 to obtain a higher integrated wall panel. The integrated wall panels on the left and right sides can also be connected by I-beam aluminum 4 clips to obtain an inner partition wall. This improves the versatility of I-beam aluminum 4 in the wall assembly process, eliminating the need to manufacture multiple connectors 18 for installation, reducing manufacturing steps, and reducing the time spent selecting accessories during installation.

[0039] There is no need to fabricate integrated wall panels one by one on the construction site, saving installation time; on-site installation only requires splicing left and right using I-beam aluminum panels, eliminating the need for on-site cutting and fabrication, which greatly improves installation efficiency and reduces construction waste.

[0040] The theoretical calculation of sound insulation is as follows: Based on the material properties of the integrated high sound insulation wall panel, and in accordance with GB / T50121-2005 "Standard for Evaluation of Building Sound Insulation", the sound insulation of the wall panel was theoretically calculated, and the overall sound insulation reached 58dB.

[0041] Table 1: Material Properties of Each Component

[0042] Table 2: Calculation of Sound Insulation of Wall Panels

[0043] Table 3: ISO Reference Sound Insulation

[0044] 500Hz serves as a "typical anchor point" for mid-to-high frequency sound insulation performance, directly determining the actual auditory experience of building sound insulation. Therefore, the sound insulation at 500Hz is selected as the evaluation standard.

[0045] According to the standard, the total adverse deviation of 1 / 3 octave (100-3150Hz, 16 frequency bands) is ≤32dB; the total adverse deviation of octave (5 frequency bands) is ≤10dB.

[0046] According to theoretical calculations, when the ISO reference sound insulation is shifted by 13dB, the total unfavorable deviation for the 1 / 3 octave band is 24.5dB, and the total unfavorable deviation for the octave band is 7.5dB, both meeting the requirements. When the shift increases to 14dB, the total unfavorable deviations increase to 31.5dB and 10.5dB respectively, exceeding the standard limits and no longer meeting the requirements. At this point, the overall sound insulation is 52 + 13 = 65dB. Considering the robustness of the project and the possible deviations in actual installation, assuming an unfavorable deviation of 0 for each frequency and reserving an allowable deviation of 2-3dB, a shift of 6-7dB meets the requirements. Conservatively taking 6dB, the overall sound insulation is 52 + 6 = 58dB.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0049] It should be noted that if the embodiments of the invention involve directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
