Description

Technical Field

[0001] The invention relates to the technical field of building materials, and in particular to a through-type acoustic impedance keel and an assembled wall. Background Art

[0002] With the development of industrialization and the popularization of prefabricated buildings, various prefabricated partitions have become increasingly popular in recent years. In the existing technology, indoor lightweight prefabricated partitions use expansion bolts to fix the ceiling and floor keels on the structural floor slabs respectively, and then install vertical light steel keels and horizontal through keels. The wall panels are fixed on both sides of the keel with screws. A single-layer cavity is formed in the middle of the keel, and the cavity is filled with sound insulation and heat preservation materials. The through keel, also known as the through keel, is a keel material commonly used in building decoration. It is mainly used in structures such as partition walls and suspended ceilings. The through keel can provide strong support for the wall or suspended ceiling and enhance the stability of the overall structure. It runs through the middle part of the partition wall or suspended ceiling, and is interconnected with other keels (such as vertical keels, ceiling and floor keels, etc.) to form a stable frame system, which effectively prevents deformation, cracking and other problems of the wall or suspended ceiling.

[0003] During the use of existing through-type keels, the existing keels are generally prefabricated parts, so their lengths are generally standard lengths. During the installation process, the height of the installation wall varies. At this time, due to the limitation of the keel length, the keels need to be assembled, and the keels located at the bottom have higher requirements on the strength of their installation connectors (because of the influence of gravity, the keels are already set on the wall, resulting in the keels actually having an upward and outward force). As a result, the connectors located at the bottom need to restrain the entire force brought by the upper part. The existing keel connectors are relatively simple, and are generally connected by connecting blocks. The connecting blocks are inserted, so the existing connecting blocks will have a protruding part. When the connecting block part is located above or below, there will be a gap between the plate and the wall, which needs to be filled in other ways, or connected by bolts. When the wall is high, the labor required for the connection is large, so it takes a lot of time to assemble the existing assembly plate into the wall. Summary of the invention

[0004] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. The embodiments of the present invention provide a through-type acoustic impedance keel and an assembled wall to solve the technical problem that the existing assembly plates require a lot of time to be assembled into a wall due to the inconvenience of connection.

[0005] The embodiment of the present invention adopts the following technical solution: a through-type acoustic impedance keel and an assembled wall, including a vertical keel with a plurality of hole structures on the surface, and a quick-connect structure for facilitating seamless and quick connection of two vertical keels.

[0006] Furthermore, the vertical keel has an S-shaped cross-section, and a plurality of trapezoidal reinforcing ribs are arranged inside the vertical keel, a connecting plate is arranged in the middle position of the vertical keel, a limiting hole is opened at one end of the vertical keel, and a damping block is arranged inside the vertical keel groove.

[0007] Furthermore, the quick-connect mechanism includes a matching trapezoidal block and a trapezoidal plug-in block, the matching trapezoidal block and the trapezoidal plug-in block are respectively located at the two ends of the vertical keel, the matching trapezoidal block is provided with a connecting hole, the trapezoidal plug-in block is provided with a deformable pressing guide block, the vertical keel is provided with a block for limiting the trapezoidal plug-in block, a connecting hole is provided in the trapezoidal plug-in block, and connecting blocks and limiting blocks are respectively provided at the outlets at both ends of the connecting hole, the limiting block is used in conjunction with the limiting hole, the connecting block is used in conjunction with the connecting hole, the limiting block and the connecting block have circular cross-sections, and the outer side surfaces of the ends of the limiting block and the connecting block are arc surfaces, and the limiting block and the connecting block are connected to the side walls of the connecting hole by springs.

[0008] Furthermore, the vertical keel is made of aluminum-zinc alloy steel.

[0009] Furthermore, the damping block is made of a deformable plastic material.

[0010] Furthermore, the center line of the connecting plate coincides with the centroid line of the vertical keel.

[0011] Furthermore, the partition board includes two outer protection boards, a middle partition board, a plurality of vertical keels and a plurality of transverse keels. The two vertical keels are connected by a plurality of transverse keels. The outer protection board is located on the surface of the vertical keels and the transverse keels. The middle partition board is located between the vertical keels and the transverse keels. Lateral sealing plates are arranged on both sides of the outer protection board. End sealing plates are arranged on the upper and lower ends of the outer protection board. The space between the outer protection board and the middle partition board is filled with heat insulation and sound insulation cotton. The outer protection board adopts a silicate board.

[0012] Furthermore, the middle partition is a ceramic microporous structure, and the ceramic microporous structure includes a plurality of semi-through holes and through holes, and adjacent holes are interconnected.

[0013] Compared with the prior art, the beneficial effects of the present invention are: First, when a number of connected semi-through holes and through holes are opened in the middle partition, the propagation path of the sound becomes extremely complicated after entering the hole. The sound will be constantly reflected and refracted inside the hole because the wall of the hole can serve as a reflection interface. Compared with ordinary flat sound-absorbing panels, this complex path greatly increases the propagation distance of the sound inside the sound-absorbing panel. The connected hole structure allows the sound waves in different holes to affect each other. When the sound waves propagate in the hole, since the holes are connected, the sound waves will interfere with each other. As for the role of the semi-through holes and through holes, when absorbing sound, the semi-through hole plate has a better sound absorption effect on low-frequency sound. Since the wavelength of low-frequency sound is longer, the semi-through hole structure can better interact with low-frequency sound waves. By adjusting the parameters such as the size and depth of the semi-through holes, effective sound absorption of specific low-frequency frequencies can be achieved. The through-hole plate performs well in absorbing medium and high-frequency sounds. The wavelength of medium and high frequency sound is shorter, and it can interact with the hole wall more frequently in the connected channels of the through-hole plate. Therefore, the combination of semi-through holes and through holes allows the middle partition to absorb noise of different wavelengths, thereby improving the sound insulation effect of the wall. Secondly, when the vertical keels are connected by the quick-connect mechanism, the quick-connect mechanism can be prefabricated in the keel during the production process, and then through the lateral sealing plate with a notch, the pre-installed quick-connect mechanism can play a marking role. At this time, during the docking installation process, if the conical plug-in block happens to be at the bottom, in order to avoid a gap between the end of the wall and the ground, if it is replaced with the previous need to be disassembled, it is difficult to disassemble due to the effect of the end sealing plate, and the quick-connect mechanism in the present invention does not need to be disassembled. At this time, after being located on the ground, the conical plug-in block will It retracts into the vertical keel to avoid interference. However, if two vertical keels are connected, the conical plug-in block will not retract, so the conical plug-in block can be connected with the matching conical block. In the process of plugging, no additional operation is required. The wall can be installed and connected by its own gravity just by placing it normally. There is no specific requirement for the installation position during the installation process. It only needs to be roughly aligned. It will also be automatically aligned when automatically connected under the action of gravity, thereby greatly reducing the complexity of wall splicing and making it more practical. To sum up, when the wall is in use, the special hole effect is used to make the sound insulation effect of the wall better. At the same time, when the walls need to be spliced, the installation requirements for the installers are lower. During the installation process, the wall's own weight can be used to complete automatic alignment and plug-in. At the same time, when it is located at the end, there will be no gap between the ground. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Combine the following Figures 1 to 7 As shown, an embodiment of the present invention provides a through-type acoustic impedance keel and an assembled wall, including a vertical keel 6 with a plurality of hole structures on the surface, and a quick-connect structure for facilitating seamless and quick connection of two vertical keels 6.

[0023] When the wall is in use, the special hole effect is used to make the sound insulation effect of the wall better. At the same time, when the walls need to be spliced, the installation requirements for the installers are lower. During the installation process, the wall's own weight can be used to complete automatic alignment and plug-in. At the same time, when it is at the end, there will be no gap between the ground.

[0024] Specifically, the cross-section of the vertical keel 6 is S-shaped, and a plurality of trapezoidal reinforcing ribs 61 are arranged inside the vertical keel 6. A connecting plate 62 is arranged in the middle position of the vertical keel 6. A limiting hole 63 is opened at one end of the vertical keel 6, and a damping block 64 is arranged inside the groove of the vertical keel 6.

[0025] During operation, the setting of the damping block 64 can limit the conical plug-in block to a certain extent. However, the damping block 64 will also deform due to the influence of its material. However, it will interfere first and then deform, ensuring that the quick-connect mechanism 7 can be used normally.

[0026] Specifically, the quick-connect mechanism 7 includes a matching trapezoidal block 71 and a trapezoidal plug-in block 73, the matching trapezoidal block 71 and the trapezoidal plug-in block 73 are respectively located at the two ends of the vertical keel 6, the matching trapezoidal block 71 is provided with a connecting hole 72, the trapezoidal plug-in block 73 is provided with a deformable pressing guide block, the vertical keel 6 is provided with a stopper 74 for limiting the trapezoidal plug-in block 73, a connecting hole is provided in the trapezoidal plug-in block 73, and a connecting block 77 and a limiting block 75 are respectively provided at the outlets at both ends of the connecting hole, the limiting block 75 is used in conjunction with the limiting hole 63, and the connecting block 77 is used in conjunction with the connecting hole 72, the limiting block 75 and the connecting block 77 have circular cross-sections, and the outer side surfaces of the ends of the limiting block 75 and the connecting block 77 are arc surfaces, and the limiting block 75 and the connecting block 77 are connected to the side walls of the connecting hole by springs.

[0027] Specifically, the vertical keel 6 is made of aluminum-zinc alloy steel.

[0028] When working, the S-shaped sound insulation section forms a spring oscillator effect when vibrated. Made of aluminum-zinc alloy steel, the section compression rebound rate reaches 15%. Reverse symmetrical sound insulation opening design, three-cavity circuitous energy dissipation, two-way pipeline preset holes, compatible with electromechanical wiring.

[0029] Specifically, the damping block 64 is made of a deformable plastic material, such as silica gel.

[0030] Specifically, the center line of the connecting plate 62 coincides with the centroid line of the vertical keel 6 .

[0031] During operation, the strength of the vertical keel 6 is improved.

[0032] Specifically, it includes two outer protection panels 3, a middle partition panel 5, a plurality of vertical keels 6 and a plurality of transverse keels 2. The two vertical keels 6 are connected by a plurality of transverse keels 2. The outer protection panels 3 are located on the surfaces of the vertical keels 6 and the transverse keels 2. The middle partition panel 5 is located between the vertical keels 6 and the transverse keels 2. Lateral sealing panels 1 are arranged on both sides of the outer protection panels 3. End sealing panels 4 are arranged at the upper and lower ends of the outer protection panels 3. Heat-insulating and sound-proof cotton is filled between the outer protection panels 3 and the middle partition panel 5. The outer protection panels 3 are made of silicate panels.

[0033] Specifically, the middle partition plate 5 is a ceramic microporous structure, which includes a plurality of semi-through holes and through holes, and adjacent holes are interconnected.

[0034] When working, the sound absorption effect of the wall is improved through the ceramic microporous structure.

[0035] Working principle: When the wall needs to be spliced, one end of the wall with the conical plug-in block is connected to the ground. At this time, the conical plug-in block is affected by the vertical force and will move horizontally upward, so that the conical plug-in block can be retracted into the vertical keel 6. When the two vertically connected vertical keels 6 are connected, the conical insertion block is inserted into the matching conical block, but at this time, the conical insertion block and the matching insertion block are in inclined contact, and the connecting block 77 provided on the conical insertion block will shrink inward due to the inclined surface of the matching conical block. At this time, there may be a partial upward force, but a deformable damping block 64 is provided above the conical insertion block, and the damping block 64 can overcome a part of the upward force, so that the connecting block 77 first deforms its position. (When in contact with the ground, although there is a damping block 64 at this time, the force is completely upward, and this force can cause the damping block 64 to deform, thereby not hindering the conical connecting block. When the connection block 77 is displaced, the liquid in the connecting groove 76 is squeezed, so that the limiting block 75 at the other end is displaced, and inserted into the limiting hole 63, so that the conical plug-in block is connected with the vertical keel 6, thereby avoiding excessive contact force between the conical insertion block and the matching insertion block on the inclined surface, resulting in the retraction of the conical plug-in block. With continuous contact, when the connection block 77 moves to the position of the connecting hole 72, it no longer resists the connection block 77. The connection block 77 rebounds under the action of the spring and is inserted into the connecting hole 72. At this time, the conical insertion block and the matching insertion block are connected. The quick connection mechanism 7 is in inclined contact. At the beginning, the interface is large, resulting in the need to align it when docking. At the same time, the connection can be completed by using the wall's own gravity. In the later use of the wall, since a number of connected semi-through holes and through holes are opened in the middle partition 5, the propagation path of sound after entering the hole becomes extremely complicated. Sound will be constantly reflected and refracted inside the hole because the wall surface of the hole can be used as a reflection interface. Compared with ordinary flat sound-absorbing panels, this complex path greatly increases the propagation distance of sound inside the sound-absorbing panel. The interconnected hole structure allows the sound waves in different holes to affect each other. When the sound waves propagate in the holes, since the holes are interconnected, the sound waves will interfere with each other. As for the role of the semi-through holes and through holes, when absorbing sound, the semi-through hole plate has a better sound absorption effect on low-frequency sound. Since the wavelength of low-frequency sound is longer, the semi-through hole structure can better interact with low-frequency sound waves. By adjusting the parameters such as the size and depth of the semi-through holes, effective sound absorption of specific low-frequency frequencies can be achieved. The through-hole plate performs well in absorbing medium and high-frequency sounds. The wavelength of medium and high-frequency sounds is shorter, and they can interact with the hole wall more frequently in the interconnected channels of the through-hole plate. For this reason, the combination of the semi-through holes and through holes allows the middle partition 5 to absorb noise of different wavelengths, thereby improving the sound insulation effect of the wall.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
