Description

Technical Field

[0001] This utility model relates to the field of building decoration structures, and in particular to a detachable wall structure. Background Technology

[0002] In the field of modern architectural interior design and spatial planning, especially in the temporary functional transformation of large public spaces, convention centers, hotel lobbies, or historical buildings, it is often necessary to re-divide or decorate spaces without altering or damaging the original main structure and finished surfaces. Temporary walls or partition structures are widely used as important means of achieving space division, guiding pedestrian flow, and enhancing environmental aesthetics and acoustic quality.

[0003] Currently, various forms of temporary partition systems exist on the market. Traditional fixed partitions, such as masonry walls or light steel keel gypsum board walls, offer good stability and sound insulation, but their construction process is complex, significantly impacts the site environment, and is difficult to modify once completed, failing to meet the needs for temporary and reversible use. For renovations of floors and walls (especially those clad in high-end stone finishes such as marble and granite), traditional fixing methods like nailing and gluing can cause permanent damage to the original finish, which is unacceptable in many high-end venues and historical building renovation projects. To address temporary space usage needs, the industry has developed various movable or modular temporary partition structures. For example, a common type is the suspended movable partition, which slides along a top track and can be opened and closed flexibly. However, this method requires a robust load-bearing structure at the top and necessitates the pre-installation of a complex track system, greatly limiting its applicability in scenarios where there are no pre-existing conditions or where alterations to the ceiling structure are not permitted.

[0004] Furthermore, in certain specific scenarios, such as when temporary backdrops or decorative walls need to be installed in front of existing glass curtain walls, stone walls, or fire exits, existing technical solutions face numerous challenges. On the one hand, it is necessary to ensure the stability and safety of the wall structure itself, especially for temporary walls with large spans and heights. How to effectively resist lateral forces without relying on connections to the original wall becomes a technical challenge. On the other hand, these temporary structures often need to possess specific functions, such as sound absorption and noise reduction to improve the acoustic environment of the space, or integration of lighting, multimedia equipment, etc.

[0005] Therefore, how to design a wall structure that can be installed and disassembled quickly and without damage, while ensuring structural stability and safety, and also achieving a beautiful curved surface effect and good acoustic function, especially in high-end environments where it is impossible or not permissible to damage the existing floor and wall finishes, has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a detachable wall structure. To achieve the above objective, the embodiments of this utility model adopt the following technical solution:

[0007] This utility model embodiment proposes a detachable wall structure, applied to walls with original steel beam structures, comprising:

[0008] Multiple square steel columns are spaced apart. The bottom of the multiple square steel columns is connected to the ground by expansion bolts, and the top of the multiple square steel columns is connected to the crossbeam. The crossbeam is connected to the original steel beam by a truss.

[0009] The longitudinally installed keel frame is connected to the square steel column by the horizontal support components.

[0010] In addition, multiple sets of multi-layered composite arc-shaped decorative components are spaced apart on the keel frame. The multi-layered composite arc-shaped decorative components include, from the inside out, a perforated metal backing plate and a shaped hard covering layer.

[0011] Preferably, multiple sets of multi-layer composite arc-shaped decorative components are connected by metal corner brackets; a sound-absorbing layer is provided on the side of the backing perforated metal plate away from the shaped hard cover layer.

[0012] Preferably, the sound-absorbing layer is a sound-absorbing cotton felt wrapped with glass fiber cloth.

[0013] Preferably, the backing perforated metal plate is a stainless steel plate with a perforated array formed thereon.

[0014] Preferably, the wall structure also includes a stainless steel brushed skirting board arranged along the length of the bottom, and the stainless steel brushed skirting board is connected to the longitudinally installed keel frame.

[0015] Preferably, the brushed stainless steel skirting board has capsule holes near the air outlet.

[0016] Preferably, it also includes a light-emitting profile disposed at the top, which is connected to the longitudinally installed keel frame and the square steel column respectively. The side of the light-emitting profile near the top is bent upward to form a light groove, and a light strip is provided in the light groove.

[0017] Preferably, the transverse support assembly includes a crossbar corresponding to the square steel column and a fireproof gypsum board disposed on the crossbar.

[0018] Beneficial effects:

[0019] This utility model provides a detachable wall structure. By fixing the bottom of the square steel columns to the ground and connecting the top to the building's original steel beam structure through beams and trusses, it ingeniously constructs an independent load-bearing support system that does not rely on the original wall. This effectively overcomes the technical defects of insufficient stability in existing temporary partition structures or the complex construction process and permanent damage to the wall finish caused by traditional fixed partitions. Compared with existing technologies, this solution completely avoids any drilling or bonding work on the wall surface, achieving non-destructive installation and convenient disassembly of existing high-end decorative environments (such as stone and wood veneer walls), and can completely restore the site to its original state after use. More importantly, the multi-layer composite curved surface component used in this solution, through the combination of a perforated metal backing plate and an external styling hard cladding layer, can not only easily achieve high-quality, customized curved surface shapes that are difficult to achieve with traditional temporary structures, greatly enhancing the aesthetic effect of the space, but its perforated structure also provides a basis for achieving excellent sound absorption, taking into account both functionality and decoration. This wall structure has significant advantages such as flexible installation, structural safety, reusability, and no environmental impact. Attached Figure Description

[0032] Example

[0033] This embodiment provides a detachable wall structure, aiming to solve the problems of poor stability of temporary wall structures in the prior art, irreversible damage to the original building walls and floor finishes during installation, and limited ability to achieve complex shapes and acoustic functions. The structural solution proposed in this embodiment, by constructing an independent, detachable support system and combining it with modular multi-layer composite surface components, enables the rapid construction of a half-height structure that combines a beautiful curved appearance, good acoustic performance, and structural stability without disrupting the original interior decoration environment.

[0034] Please see Figures 1 to 8This embodiment discloses a detachable wall structure 10, whose core application scenario is an interior space that has been fully decorated and has an original steel beam structure 11, such as the wall 12 in front of a high-end hotel lobby, conference center, exhibition hall, etc. The wall structure 10 mainly includes a main support frame system, a secondary keel system for installing decorative panels, and a multi-layer composite arc-shaped decorative component 19 modularly installed on the keel system.

[0035] First, its main support frame system is described in detail. This system is the load-bearing and stabilizing foundation of the entire wall structure 10. Its key design feature is that all structural loads are directly transferred to the original load-bearing structure at the ground and top of the building, thereby completely avoiding any destructive rigid connections with the lateral walls 12, which are non-load-bearing or decorative surfaces.

[0036] like Figure 6 As shown, the main support frame system includes multiple square steel columns 13 spaced apart along the extension direction of the wall structure 10. These square steel columns 13 are the main vertical load-bearing components of the structure. In this embodiment, the square steel columns 13 are preferably made of rectangular or square hollow steel of national standard Q235B or higher strength grade. Their material selection and dimensions need to be precisely determined through structural calculations based on factors such as the overall height and span of the wall structure and the weight of the cladding to be borne, to ensure sufficient strength, rigidity, and stability. The spacing of the square steel columns 13 also needs to be calculated, typically between 1.5 meters and 2.5 meters, to ensure effective support for the superstructure and the stability of the overall frame.

[0037] The base of each square steel column 13 is securely connected to the building's ground 15 in a specific manner. For example... Figure 6 As shown, the connection method uses at least two (usually four) expansion bolts 14. During construction, the installation point of each square steel column 13 is first precisely determined according to the design drawings, and holes are drilled at the corresponding positions on the ground 15. To protect the floor finish (such as marble, floor tiles, etc.), professional tools should be used during drilling, and dust and noise reduction measures should be taken. After drilling, heavy-duty mechanical or chemical expansion bolts 14 are inserted. Then, the square steel column 13, pre-welded with a connecting base plate, is hoisted into place, aligning the pre-drilled holes on the base plate with the expansion bolts 14. Finally, the square steel column 13 is firmly fixed to the ground 15 by tightening the nuts. This connection method has high load-bearing capacity, is easy to install, and when the wall structure is demolished, only the bolts need to be unscrewed, leaving only a few small holes in the ground, making repairs easy and maximizing the protection of the original ground integrity.

[0038] like Figure 6 and Figure 7As shown, the tops of multiple square steel columns 13 are connected together to form a unified top constraint. Specifically, the tops of all square steel columns 13 are fixed to one or more continuous crossbeams 16 by welding or high-strength bolts. The crossbeams 16 are typically made of steel with the same or larger cross-section as the square steel columns 13 (such as H-beams or thicker square steel tubes), and their function is to integrate the top support points of all columns, forming a unified horizontal support surface, and providing a foundation for the subsequent connection with the original building structure.

[0039] To achieve connection with the building's roof structure and ensure the ultimate stability of the entire wall structure frame, beam 16 is connected to the original steel beam structure 11 at the building's roof via a specially designed truss structure. In many large public buildings, there is often an original steel beam structure 11 above the ceiling to support the roof, floors, or large equipment. This embodiment utilizes this existing condition. Figure 7 As shown, the truss structure can be a spatial truss or planar truss welded from angle steel, channel steel, or round steel pipes. One end is firmly connected to the crossbeam 16, and the other end is connected to the original steel beam structure 11 through specially designed connectors (such as U-shaped clamps, bolt connection plates, etc.). This connection method has a certain degree of flexibility and can adapt to different positions and sizes of the original steel beam structure 11 on site, and it is also detachable. Through the fixation of the bottom ground 15 and the connection of the top to the original steel beam structure 11, the entire main support frame forms an extremely stable independent structural system in the vertical plane, which can effectively resist its own gravity load and possible lateral thrust without applying any force to the adjacent wall 12.

[0040] Next, the secondary keel system used for installing the decorative panels is described. This system is attached to the main support frame, providing a precise mounting surface for the subsequent veneer components. The system mainly consists of horizontal support components 17 and longitudinal mounting keel frames 18.

[0041] like Figure 7 and Figure 8 As shown, the transverse support assembly 17 serves as a bridge connecting the main support frame (square steel columns 13) and the longitudinally installed keel frame 18. In a preferred embodiment, the transverse support assembly 17 includes multiple horizontal bars 30 corresponding to the position of each square steel column 13. These horizontal bars 30 can be C-shaped steel, rectangular steel pipes, or angle steel, and they are horizontally welded or bolted to the side of the square steel column 13 facing the finished surface at certain intervals (e.g., 600mm each) in the vertical direction. The length of the horizontal bars 30 determines the thickness of the wall structure. On the outside of the horizontal bars 30, one or more layers of fireproof gypsum board 31 can be installed according to fireproof and other functional requirements. The fireproof gypsum board 31 not only improves the fire resistance rating of the entire structure but also provides a flatter base surface for the installation of the main keel.

[0042] The longitudinally mounted keel frame 18 is the framework that directly supports and fixes the multi-layer composite curved decorative component 19. It is typically constructed of light steel keel or aluminum alloy profiles, which are densely arranged vertically and fixed to the transverse support components 17 (i.e., the crossbars 30 and the fireproof gypsum board 31 on them) using self-tapping screws or special connectors. The arrangement of the longitudinally mounted keel frame 18 and the curvature of the profiles precisely define the final curved profile of the wall structure. During construction, the light steel keel needs to be pre-processed and bent according to the curve requirements of the design drawings, or flexible, bendable keels should be used to ensure that the final installation base surface is smooth and continuous, providing a guarantee for the installation of the curved decorative component.

[0043] Finally, one of the core elements of this embodiment will be explained in detail: the multiple sets of multi-layered composite curved decorative components 19 mounted on the longitudinally installed keel frame 18. These components are the ultimate embodiment of the wall structure's aesthetic effect and specific functions (such as sound absorption). Figures 1 to 5 As shown, the curved appearance of the entire wall structure is composed of multiple independent decorative components 19 spliced ​​together.

[0044] Each set of multi-layered composite curved decorative components 19 has a composite layered structure from the inside out. For example... Figure 8 As shown in detail, the innermost layer (the layer closest to the longitudinally mounted keel frame 18) is a perforated metal backing plate 20. In a preferred embodiment, this perforated metal backing plate 20 is made of stainless steel or galvanized steel. The key feature is that a dense array of perforations 24 is formed on the plate. These perforations can be circular, square, or other shapes, and their aperture and spacing (i.e., perforation rate) are acoustically designed to allow sound waves to penetrate the metal plate smoothly, rather than be reflected back. The main function of this perforated metal plate 20 is to serve as the structural substrate of the entire cladding assembly, providing the necessary strength and flexural shaping, while also being a key channel for achieving sound absorption.

[0045] Preferably, a sound-absorbing layer 23 is provided on the inner side (facing the keel frame) of the perforated metal plate 20, away from the rigid cladding layer. The sound-absorbing layer 23 is the main component for achieving sound absorption and noise reduction in the wall structure. Preferably, the sound-absorbing layer 23 can be made of sound-absorbing cotton felt wrapped with fiberglass cloth. When external sound waves pass through the perforated metal plate 20, they enter the sound-absorbing layer 23, which is composed of porous materials. The sound energy is rubbed and vibrated in the countless tiny pores of these materials, thus being largely converted into heat energy and dissipated, achieving the effect of reducing spatial reverberation and absorbing noise. The thickness and density of the sound-absorbing layer 23 also need to be determined based on the target sound absorption frequency and sound absorption coefficient.

[0046] The outermost layer of the multi-layered composite curved decorative component 19, which is the final visual layer presented to the viewer, is the styling hard panel layer 21. The styling hard panel layer 21 is the part that determines the final appearance and texture of the wall structure. It is usually composed of a shaped baseboard (such as thin bentwood board, PVC foam board, etc.), a layer of cushioning sponge or cork, and an outermost decorative fabric (such as leather, velvet, linen, etc.). By laminating these materials onto a backing perforated metal panel 20 that has been bent into shape according to the design curvature, a whole hard panel unit with a soft texture and precise curvature is formed.

[0047] In actual production, each set of multi-layer composite curved decorative components 19 is a modular unit prefabricated in the factory. During on-site installation, these prefabricated component units are simply installed onto the longitudinally mounted keel frame 18 using specific fasteners (such as hangers and screws). To ensure the tightness and continuity of the splicing between multiple sets of decorative components 19, forming a perfect integral curved surface, preferably, adjacent sets of multi-layer composite curved decorative components 19 are connected by metal corner brackets 22 for auxiliary fixing and fine-tuning. Figure 2 and Figure 4 As shown in the enlarged view, the metal corner bracket connection 22 can be hidden at the joint of the components and is not visible from the outside. It ensures that the edges of adjacent units are on the same curved surface and maintains a uniform gap or achieves a seamless splice. To enhance the overall sophistication and functionality of the wall structure, this embodiment also includes some preferred additional components.

[0048] like Figure 6 and Figure 8 As shown, the wall structure 10 preferably also includes a continuously installed stainless steel brushed skirting board 25 along its bottom length. This stainless steel brushed skirting board 25 is connected to the bottom of the longitudinally mounted keel frame 18 or the bottom of the square steel column 13 via clips or screws. The skirting board 25 serves two purposes: firstly, it protects the bottom of the wall structure from impacts and wear caused by daily activities such as walking and cleaning; secondly, it provides finishing and decoration, making the transition between the wall structure and the floor 15 more natural and aesthetically pleasing. In situations where ventilation or equipment heat dissipation is required, preferably, the stainless steel brushed skirting board 25 can also be provided with capsule holes or strip grilles near the air outlet or equipment to ensure air circulation.

[0049] like Figure 6 and Figure 7As shown, to create a specific atmosphere, the wall structure 10 preferably includes a luminous profile 27 at its top. This luminous profile 27 is typically a custom-made aluminum alloy profile or a bent stainless steel piece, which can be connected to the top of the longitudinally mounted keel frame 18 and the top of the square steel column 13 via connectors, becoming a decorative edge strip at the top of the wall structure. More ingeniously, the side of the luminous profile 27 near the top can be designed to bend upwards to form a light trough 28. LED light strips 29 can be pre-installed within the light trough 28. When the light strips 29 are lit, the light shines upwards onto the ceiling, creating soft indirect or ambient lighting, further enhancing the decorative effect of the wall structure and the overall lighting quality of the space.

[0050] In summary, this embodiment successfully constructs a fully functional and high-performance detachable wall structure through the collaborative design and combination of the aforementioned components. The installation process can be roughly summarized as follows: ground positioning and layout → drilling and installing expansion bolts → hoisting and fixing square steel columns → installing top beams and connecting trusses → installing horizontal support components → installing longitudinal keel frame → modularly installing multi-layer composite curved decorative components → installing bottom skirting boards and top luminous profiles. The entire process is clear, mostly dry work, with minimal impact on the site environment and high installation efficiency. When dismantling is required, the process can be carried out in reverse order, and all components can be recycled and reused, truly achieving green, environmentally friendly, and reversible temporary space construction. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. For those skilled in the art, this utility model can have various modifications or variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
