Description

Technical Field

[0001] This invention relates to the field of prefabricated wall technology, and in particular to a quick-installation connection structure for prefabricated decorative wall panels. Background Technology

[0002] Prefabricated decoration, as an industrialized decoration model vigorously promoted in the current construction and decoration field, differs from traditional on-site wet construction. Its core feature lies in the standardized prefabrication of various components such as wall decoration components, keel frames, and connectors in factories, which are then transported to the construction site for modular assembly, eliminating the need for on-site plastering, painting, and other wet processes. Among them, prefabricated walls, as a core component of the prefabricated decoration system, mainly serve the core functions of space partitioning, decorative enclosure, and functional zoning.

[0003] In public medical and emergency building scenarios such as hospitals, health centers, temporary treatment areas, and emergency isolation points, due to practical needs such as adjusting treatment layouts, dividing wards for isolation, temporary epidemic prevention and control, and optimizing bed movement, it is often necessary to temporarily construct interior partitions to flexibly divide existing spaces to meet special usage requirements such as medical treatment and isolation protection. These temporary partitions are not permanently fixed installations and often need to be frequently disassembled, relocated, reassembled, and reused according to changes in on-site operational arrangements and actual needs. This places higher demands on the efficiency of partition construction, ease of disassembly and assembly, and structural integrity after reuse.

[0004] Currently, most prefabricated wall connection structures in existing technologies are designed for permanent or semi-permanent walls. Their connection methods mostly adopt welding, multiple bolt locking, complex buckle nesting, or adhesive fixing, which cannot meet the actual usage needs of rapid construction, frequent disassembly and reassembly, and cyclical reuse of temporary partitions in special scenarios such as hospitals. They have defects such as low assembly efficiency, inconvenient disassembly and assembly, low reuse rate, and easy structural damage. Summary of the Invention

[0005] To better meet the practical needs of rapid construction, frequent disassembly and reassembly, and repeated use of temporary partitions in special settings such as hospitals, this application provides a prefabricated quick-installation connection structure for decorative walls.

[0006] The prefabricated quick-installation connection structure for decorative walls provided by this invention adopts the following technical solution: A prefabricated quick-installation connection structure for decorative walls is disclosed, used to install partition walls on a keel frame. The structure includes a mounting base fixedly mounted on the keel frame. The mounting base has a negative pressure chamber and a locking block on its inner side facing the partition wall. The partition wall is a high-airtightness partition wall, with a locking hole for the locking block to pass through horizontally. The partition wall also has a one-way air valve and a balancing valve horizontally aligned with the negative pressure chamber. The negative pressure chamber is sealed by the fit between the partition wall and the mounting base. The one-way air valve connects to a negative pressure pump, which creates a negative pressure environment in the negative pressure chamber. The balancing valve is openable and closeable; when open, it restores the negative pressure chamber to atmospheric pressure.

[0007] Preferably, the mounting base has a first telescopic hole, and the locking block is horizontally telescopically disposed in the first telescopic hole of the mounting base. The locking block retracts inward as the air pressure in the negative pressure chamber decreases. When the locking block is in its extreme extended position, its outer end protrudes from the outer surface of the partition wall. When the locking block is in its extreme shortened position, its outer end is flush with the outer surface of the partition wall.

[0008] Preferably, the mounting base has an adjustment chamber, and the adjustment chamber is equipped with a slider. The slider slides in a sealed manner within the adjustment chamber, dividing the adjustment chamber into a first adjustment cavity and a second adjustment cavity. The first adjustment cavity is connected to the negative pressure chamber. The slider is connected to a return spring, and the elastic force of the return spring and the negative pressure of the negative pressure chamber control the slider to move in two opposite directions, respectively. The second adjustment cavity is connected to the first telescopic hole, and the slider is connected to the locking block by a linkage assembly.

[0009] Preferably, the linkage component includes a connecting rod, a connecting plate, and a guide groove. One end of the connecting plate is connected to the slider, and the guide groove is formed in the connecting plate. One end of the connecting rod is connected to the locking block, and the other end passes through the guide groove. The locking block extends and retracts based on the change in the relative position of the connecting rod and the guide groove.

[0010] Preferably, a flexible pad is movably provided on the side wall of the card block, and an internal support mechanism is provided between the card block and the mounting base. The internal support mechanism expands the flexible pad as the card block contracts.

[0011] Preferably, the side wall of the card block has a placement groove, and the flexible pad is disposed in the placement groove; the inner support mechanism includes a plug rod, a support rod, and a support plate, the plug rod is disposed at the bottom of the first telescopic hole, and the inner end of the card block has a slot for inserting the plug rod; the bottom of the placement groove has a second telescopic hole, the second telescopic hole communicates with the slot, and the support rod is telescopically disposed in the second telescopic hole; the support plate is connected to the outer end of the support rod, and the support plate abuts against the inner side of the flexible pad.

[0012] Preferably, the mounting base is fixedly disposed at the intersection of the keel frame, and the inner side of the partition wall is provided with a groove, so that when the partition wall is installed on the mounting base, the mounting base is embedded in the groove.

[0013] Preferably, the negative pressure chamber includes five sub-chambers, namely a central sub-chamber located at the center of the mounting base and four peripheral sub-chambers distributed around the central sub-chamber, with air passages connecting the central sub-chamber and the four peripheral sub-chambers in a one-to-one correspondence.

[0014] Preferably, the outer side of the card block is coated with a bright color.

[0015] Preferably, the partition wall is one of a metal panel, a glass panel, a plastic panel, and a ceramic panel.

[0016] The beneficial effects of this invention are as follows: 1. Compared to existing technologies, the prefabricated quick-installation connection structure for decorative walls of this invention only requires creating or removing a negative pressure environment within the negative pressure chamber of the mounting base to quickly assemble and disassemble the partition wall. This avoids damage to the partition wall during frequent assembly and disassembly, effectively adapting to the rapid construction, frequent disassembly, and reuse of temporary partition walls in special scenarios such as hospitals. Furthermore, since the partition wall, as a wall surface, is the exposed part of the prefabricated wall structure, it is more prone to wear and tear compared to other wall structures. 2. Based on the present invention, it is also possible to quickly replace a damaged partition wall that serves as a wall surface by creating or removing a negative pressure environment in the negative pressure chamber of the mounting base, without having to remove the connectors one by one. 3. During the process of using a negative pressure pump to create a negative pressure environment in the negative pressure chamber, the success of the negative pressure environment can be judged by observing whether the locking block retracts smoothly to its extreme shortening position, thus ensuring the installation effect. In addition, after the partition wall is installed, the installation status of the partition wall can be quickly and intuitively judged by judging the status of the locking block, so as to intuitively remind relevant personnel to maintain the negative pressure chamber. 4. As the locking block retracts inward during negative pressure installation, the internal support mechanism will gradually open the flexible pads on both sides of the locking block, further tightening the locking block and the partition wall, thus improving the stability of the partition wall after installation. Conversely, when the locking block extends outward as the negative pressure installation is released, the tension between the locking block and the partition wall will be released simultaneously, facilitating the subsequent disassembly and assembly of the partition wall.

[0019] The following will combine Figures 1-6 The present invention will be further illustrated by the embodiments.

[0020] Currently, existing prefabricated wall technologies mostly employ welding, multiple bolt locking, complex snap-fit ​​nesting, or adhesive fixing methods for connection. While these methods can ensure the overall structural stability of the wall after installation to a certain extent and meet the needs of conventional scenarios, they have significant technical drawbacks: First, the assembly process is cumbersome, requiring professional construction personnel to operate with specialized tools, resulting in low assembly efficiency and failing to meet the needs of rapid temporary partition construction in scenarios such as hospitals. Second, disassembly and assembly are difficult, requiring the removal of bolts, damage to snap-fits, or cleaning of adhesive layers one by one. This is not only time-consuming and labor-intensive, but repeated disassembly and assembly can easily cause deformation of connectors, damage to wall panel edges, and damage to the keel, making components unusable and increasing usage costs. Third, some connection structures are difficult to reassemble accurately after disassembly, and reinstallation can easily lead to problems such as poor wall flatness and loose connections, affecting the safety and decorative effect of the partition wall.

[0021] In summary, existing prefabricated wall connection structures cannot meet the practical needs of rapid assembly, frequent disassembly, and repeated use of temporary partitions in special scenarios such as hospitals. They suffer from drawbacks such as low assembly efficiency, inconvenient disassembly, low reusability, and susceptibility to structural damage. Therefore, this invention aims to propose a prefabricated quick-assembly connection structure for decorative walls that is simple in structure, easy to assemble and disassemble, has a strong connection, and can be repeatedly disassembled and used, to overcome the shortcomings of existing technologies and adapt to the special usage requirements of scenarios such as hospitals.

[0022] Reference Figure 1 and Figure 2 The prefabricated quick-installation connection structure for decorative walls of this invention is used to install partition walls 3 onto a keel frame 1. The keel frame 1 includes top and bottom keels, vertical keels, horizontal keels, and edge keels. The top and bottom keels are fixed to the top floor slab and ground using expansion bolts, serving as the basic positioning components for the vertical keels. The vertical keels are installed vertically between the top and bottom keels, providing the main support for bearing the panel load. The horizontal keels are installed horizontally between the vertical keels, reinforcing and preventing wall deformation. The edge keels connect to the structural walls / columns on both sides, ensuring reliable fixation of the partition wall 3 to the main structure.

[0023] Reference Figure 1 and Figure 2 The prefabricated wall panel quick-installation connection structure includes a mounting base 2, which is fixed to the keel frame 1 by bolts. Although the mounting base 2 is also fixed to the keel frame 1 by bolts, similar to existing technology, it is smaller, stronger, and has a more flexible shape design than the partition wall 3. Therefore, it is easier to assemble and disassemble and can better ensure that it is not easily deformed after multiple installations. The mounting base 2 can be installed in the area enclosed by vertical and horizontal keels, or at the intersection of vertical and horizontal keels.

[0024] Reference Figure 3 and Figure 4 The mounting base 2 has a negative pressure chamber on the side facing the inner side of the partition wall 3. In this embodiment, the negative pressure chamber includes five sub-chambers. The five sub-chambers are a central sub-chamber 41 located in the center of the mounting base 2 and four edge sub-chambers 42 distributed in a rectangular shape around the central sub-chamber 41. The central sub-chamber 41 and the four edge sub-chambers 42 are connected to each other by air passages 43, so that the air pressure between each sub-chamber of the negative pressure chamber is always consistent.

[0025] Reference Figure 3 and Figure 4 The mounting base 2 facing the inner side of the partition wall 3 is also provided with a locking block 51. The locking block 51 is a rectangular block. In this embodiment, there are two locking blocks 51. Both locking blocks 51 are vertically arranged on the mounting base 2, and the two locking blocks 51 are symmetrically arranged on the left and right sides of the central compartment 41.

[0026] Reference Figures 1 to 3The partition wall 3 is a high-airtightness partition wall, such as a smooth surface panel like a metal panel, glass panel, plastic panel, or ceramic panel, which is not easily breathable after being attached to the mounting base 2. The partition wall 3 has a through-hole 52 along its thickness direction. There are two through-holes 52 corresponding to the number and position of the locking blocks 51, and the cross-sectional shape of the through-hole 52 corresponds to the cross-sectional shape of the locking block 51. This allows the two locking blocks 51 to pass through the two through-holes 52 simultaneously in the horizontal direction when the partition wall 3 is installed on the mounting base 2, until the inner side of the partition wall 3 is attached to the mounting base 2.

[0027] Reference Figure 1 and Figure 2 The partition wall 3 is equipped with a one-way air valve 61 and a balance valve 62. The one-way air valve 61 and the balance valve 62 are arranged adjacent to each other. Both the one-way air valve 61 and the balance valve 62 are vented along the thickness direction of the partition wall 3. After the partition wall 3 is installed, the one-way air valve 61 and the balance valve 62 are horizontally aligned with the central compartment 41 of the negative pressure chamber.

[0028] Reference Figures 1 to 3 The negative pressure chamber achieves initial sealing through the contact between the partition wall 3 and the mounting base 2. Then, a one-way valve connects to the negative pressure pump. The pump's operation creates a negative pressure environment within the chamber, resulting in a pressure difference between the inner and outer sides of the partition wall 3. This causes the partition wall 3 to adhere tightly to the mounting base 2 under atmospheric pressure. It should be noted that the force forcing the partition wall 3 away from the mounting base 2 is primarily its weight. The locking block 51 supports the partition wall 3 vertically; therefore, the pressure generated by the pressure difference in the negative pressure chamber only needs to ensure that the partition wall 3 does not easily leave the mounting base 2 horizontally. The one-way valve 61 consists of a valve seat and a floating plug (such as a silicone diaphragm). When the negative pressure pump draws air, the air in the negative pressure chamber pushes open the floating plug and is discharged. After pumping stops, the negative pressure in the chamber sucks the floating plug shut, preventing air backflow.

[0029] Reference Figure 1 and Figure 2 The balancing valve 62 can be opened and closed, and it is only opened when the partition wall 3 needs to be disassembled. When the balancing valve 62 is opened, the negative pressure chamber is reconnected to the external atmospheric environment, restoring the negative pressure chamber to atmospheric pressure. At this time, the partition wall 3 can easily move horizontally away from the mounting base 2 for quick disassembly. In this embodiment, the balancing valve 62 is a push-button valve, which is normally closed. When pressed, it moves the valve core inward, allowing the external environment to flow into the negative pressure chamber and restoring pressure balance.

[0030] In summary, compared to existing technologies, the prefabricated quick-installation connection structure for decorative walls of the present invention can quickly assemble and disassemble the partition wall 3 simply by creating or removing a negative pressure environment within the negative pressure chamber of the mounting base 2. This avoids damage to the partition wall 3 during frequent assembly and disassembly, effectively adapting to the rapid construction, frequent disassembly, and reuse of temporary partition walls 3 in special scenarios such as hospitals. Furthermore, since the partition wall 3, as a wall surface, is the exposed part of the prefabricated wall structure, it is more prone to wear and tear compared to other wall structures. Based on the present invention, damaged partition walls 3 can be quickly replaced by creating or removing a negative pressure environment within the negative pressure chamber of the mounting base 2, without having to disassemble each connector individually.

[0031] In some embodiments, a sealing structure is provided around the negative pressure chamber, and the sealing effect of the negative pressure chamber is improved by the sealing structure when the partition wall 3 is in contact with the mounting base 2.

[0032] Reference Figures 1 to 5 The mounting base 2 has two horizontally formed first telescopic holes 21. The cross-sectional shape of the first telescopic holes 21 corresponds to the cross-sectional shape of the locking blocks 51. The two locking blocks 51 are telescopically positioned within the two first telescopic holes 21 in a one-to-one correspondence. The locking blocks 51 retract inward as the air pressure in the negative pressure chamber decreases, and conversely, they extend outward as the air pressure in the negative pressure chamber increases. When the locking blocks 51 are in their maximum extended position, their outer ends protrude from the outer surface of the partition wall 3; when the locking blocks 51 are in their maximum shortened position, their outer ends are flush with the outer surface of the partition wall 3. Based on this design, on the one hand, during the process of using a negative pressure pump to create a negative pressure environment in the negative pressure chamber, the success of the negative pressure environment can be determined by observing whether the locking block 51 retracts smoothly to its extreme shortened position, thus ensuring the installation effect. On the other hand, after the installation of the partition wall 3 is completed, the installation status of the partition wall 3 can be quickly and intuitively determined by judging the state of the locking block 51. For example, when the negative pressure chamber leaks, although the locking block 51 has a safety redundancy effect, preventing the partition wall 3 from easily falling off under the support of the locking block 51, as long as a leak occurs, the locking block 51 will extend completely outward due to the elimination of the negative pressure environment, intuitively reminding relevant personnel to maintain the negative pressure chamber in case of leakage. Similarly, when a significant change in the environment causes the pressure difference between the negative pressure chamber and the outside to decrease, the locking block 51 will also extend outward, again intuitively reminding relevant personnel to maintain the negative pressure chamber in case of insufficient pressure difference between the negative pressure chamber and the outside environment.

[0033] Reference Figure 1 and Figure 2Furthermore, the outer side of the card block 51 is coated with a bright color, such as bright red, so that the card block 51 is easily noticed by relevant personnel when it is partially or fully extended. In other embodiments, the bright color coating can also be a gradient color, so that relevant personnel can accurately judge the status represented by the extension of the card block 51 not only from the extension length of the card block 51, but also from the difference in the extension color.

[0034] Reference Figure 3 and Figure 4 The mounting base 2 has two adjustment chambers, which extend horizontally to the left and right sides of the central chamber 41, respectively. Each adjustment chamber is equipped with a slider 73, which slides in a sealed manner along the length of the adjustment chamber, dividing it into a first adjustment cavity 71 and a second adjustment cavity 72. The sizes of the first and second adjustment cavities change synchronously with the sliding of the slider 73. The first adjustment cavity 71 is connected to the central chamber 41 of the negative pressure chamber. Furthermore, the slider 73 is connected to a return spring 74, which can be located in either the first or second adjustment cavity 72. In this embodiment, the return spring 74 is located in the first adjustment cavity 71. A spring base 75 is fixedly installed in the first adjustment cavity 71. One end of the return spring 74 is connected to the spring base 75, and the other end is connected to the slider 73. The spring base 75 has a vent hole to ensure air pressure balance on both sides of the spring base 75. The elastic force of the return spring 74 and the negative pressure of the negative pressure chamber control the slider 73 to move in two opposite directions. When the pressure difference between the negative pressure chamber and the outside atmosphere gradually increases, the negative pressure causes the slider 73 to move closer to the central chamber 41 and compress the return spring 74. When the pressure difference between the negative pressure chamber and the outside atmosphere gradually decreases, the elastic force stored in the return spring 74 is gradually released, causing the slider 73 to move away from the central chamber 41. Ultimately, the slider 73 moves in two different directions according to the change in air pressure inside the negative pressure chamber.

[0035] Reference Figure 3 and Figure 4The second adjustment cavity 72 communicates with the first telescopic hole 21. The slider 73 and the locking block 51 are connected by a linkage assembly, which is located between the second adjustment cavity 72 and the first telescopic hole 21. Specifically, the first telescopic hole 21 is located below the second adjustment cavity 72, and the top of the first telescopic hole 21 communicates with the bottom of the second adjustment cavity 72. The linkage assembly includes a connecting rod 81, a connecting plate 82, and a guide groove 83. One end of the connecting plate 82 is connected to the slider 73, and the guide groove 83 is obliquely opened in the connecting plate 82. One end of the connecting rod 81 is connected to the locking block 51, and the other end passes through the guide groove 83. Furthermore, the direction of movement of the connecting block in the second adjustment cavity 72 and the direction of movement of the locking block 51 in the first telescopic hole 21 are perpendicular to each other on the vertical projection plane, and the length direction of the guide groove 83 and the direction of movement of the connecting plate 82 in the second adjustment cavity 72 form an acute angle. Therefore, the cooperation between the connecting rod 81 and the guide groove 83 realizes the orthogonal movement conversion between the slider 73 and the locking block 51, so that the locking block 51 extends and retracts based on the change in the relative position of the connecting rod 81 and the guide groove 83. The movement of the connecting rod 81 is controlled by the movement of the slider 73. Therefore, by setting the tilt direction of the guide groove 83, the locking block 51 can be made to retract inward as the air pressure in the negative pressure chamber decreases and extend outward as the air pressure in the negative pressure chamber increases.

[0036] Reference Figure 3 and Figure 4 The end face of the mounting base 2 is provided with a removable cover plate 22 at the adjustment chamber. The inner wall surface of the cover plate 22 serves as one of the inner wall surfaces of the adjustment chamber. By providing the removable cover plate 22, it is convenient to install parts such as the slider 73, the return spring 74, and the linkage assembly in the adjustment chamber.

[0037] Reference Figure 4 and Figure 6Flexible pads 93 are movably disposed on both sides of the locking block 51. In this embodiment, the flexible pads 93 are rubber pads, and an internal support mechanism is provided between the locking block 51 and the mounting base 2. The internal support mechanism expands the flexible pads 93 as the locking block 51 retracts. Specifically, placement grooves 91 are provided on both the left and right side walls of the locking block 51, and the flexible pads 93 are disposed in the placement grooves 91. The internal support mechanism includes a rod 94, a support rod 95, and a support plate 96. The rod 94 is disposed at the bottom of the first telescopic hole 21, and a slot for inserting the rod 94 is provided at the inner end of the locking block 51. As the locking block 51 retracts inward, the rod 94 is further inserted into the slot. The bottom of the placement slot 91 is also provided with a second telescopic hole 92, which communicates with the slot. The support rod 95 is telescopically installed in the second telescopic hole 92. The support rod 95 expands outward as the insertion rod 94 is inserted deeper, and the inner end of the insertion rod 94 is rounded to make the contact between the insertion rod 94 and the support rod 95 smoother. The support plate 96 is connected to the outer end of the support rod 95 and abuts against the inner side of the flexible pad 93. As the support rod 95 expands, it tightens the flexible pad 93 between the locking block 51 and the partition wall 3. With the above configuration, when the locking block 51 retracts inward as the negative pressure installation proceeds, the inner support mechanism will gradually expand the flexible pads 93 on both sides of the locking block 51, further tightening the locking block 51 and the partition wall 3, and improving the stability of the partition wall 3 after installation. Conversely, when the locking block 51 extends outward as the negative pressure installation is released, the tension between the locking block 51 and the partition wall 3 will also be released simultaneously, making it easier to disassemble and reassemble the partition wall 3 later.

[0038] Reference Figure 1 and Figure 2 In this embodiment, the mounting base 2 is fixedly set at the intersection of the vertical keel and the horizontal keel of the keel frame 1. Based on this, a groove needs to be opened on the inner side of the partition wall 3. When the partition wall 3 is installed on the mounting base 2, the mounting base 2 is embedded in the groove, so that in addition to the locking block 51, the mounting base 2 also plays the role of supporting the partition wall 3 in the vertical direction.

[0039] The implementation principle of the prefabricated quick-installation connection structure for decorative walls in this embodiment is as follows: After the keel frame 1 is erected, the mounting base 2 is first fixed to the intersection of the vertical and horizontal keels of the keel frame 1 using bolt assemblies, and it is ensured that the balance valve 62 is closed. Then, the partition wall 3 is first erected on the mounting base 2. At this time, the mounting block and the clamping block 51 are attached to the partition wall 3. Then, the one-way air valve 61 of the partition wall 3 is connected by a negative pressure pump, and the pressure difference between the negative pressure chamber and the atmospheric environment is gradually increased by the operation of the negative pressure pump. During this process, the locking block 51 gradually retracts inward, and the flexible pads 93 on both sides of the locking block 51 gradually tighten until the outer end face of the locking block 51 is flush with the outer end face of the partition wall 3, thus completing the installation of the partition wall 3. If the locking block 51 gradually protrudes outward, relevant personnel can promptly detect this and perform corresponding maintenance. Furthermore, when the partition wall 3 needs to be removed or replaced, simply opening the balance valve 62 on the partition wall 3 will quickly release the negative pressure in the negative pressure chamber, making it easier to remove the partition wall 3.

[0040] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
