Description

Technical Field

[0001] This invention relates to the field of building decoration and renovation technology, specifically to an installation method for a quick-installation and quick-removal modular wall system for rental housing. Background Technology

[0002] The rental housing market, especially long-term rental apartments and affordable rental housing, is characterized by high turnover rates for renovations, flexible spatial layout adjustments, strict cost control for renovations, high environmental protection requirements, and a strong need to preserve the original condition of the buildings. Traditional wall decoration techniques and existing modular wall technologies are not suitable for the special usage scenarios of rental housing. The core shortcomings are as follows: Firstly, traditional wet-work wall decoration is inefficient and damages the main structure of the building. Rental housing generally uses traditional techniques such as brick partition walls, light steel keel gypsum board partition walls, and on-site puttying and painting. The construction process involves cement mortar, wet work, on-site cutting, drilling and fixing, and painting. Not only is the construction cycle long, requiring 3-7 days for wall decoration of a single unit, but the demolition also requires violent removal, which can easily damage the floor slab, ceiling, and original wall structure, leaving a lot of holes and damage marks. Secondary renovations require repairs, which greatly increases renovation costs and turnaround time, and does not meet the operational needs of rental housing for rapid vacancy, rapid renovation, and rapid rental.

[0003] Secondly, existing modular wall panels lack versatility and cannot achieve true quick installation and disassembly. Most existing modular wall panels on the market are designed for fixed residential and commercial spaces, and are mostly fixed using adhesives, nails, or expansion bolts. Once installed, they are either impossible to disassemble or extremely difficult to disassemble, and the panels and connectors are easily damaged, making them unusable. While some modular wall panels use a splicing structure, the splicing gaps are large, the sealing is poor, and the sound insulation is weak. Furthermore, they lack standardized dimensions suitable for rental housing, making them unsuitable for universal installation across different apartment types and ceiling heights. Extensive on-site cutting and adjustments are still required, contradicting the original intention of modular standardization.

[0004] Thirdly, environmental protection and living performance standards are not met. Traditional wall decoration uses a large amount of adhesives, putty, and paint, resulting in a large release of harmful gases such as formaldehyde and VOCs. After decoration, it is necessary to ventilate for a long time to dissipate the odor, which prolongs the vacancy period of the property. Existing modular walls are mostly single-layer structures with poor sound insulation, heat insulation, and moisture-proof performance, which cannot meet the living comfort requirements of rental housing. In addition, the walls do not have pre-reserved interfaces for functions such as pipelines, sockets, and storage, and later renovations require additional drilling, which damages the integrity of the wall.

[0005] Fourth, the reuse rate is low and the operation and maintenance costs are high. Rental housing needs to be renovated every 1-3 years. Traditional wall materials are completely scrapped after dismantling, resulting in a large amount of construction waste, which does not meet the requirements of green environmental protection. Most of the existing modular wall connectors are disposable components that cannot be recycled. The overall reuse rate of decoration materials is less than 20%, resulting in high long-term operating costs. In addition, the disposal of construction waste increases additional costs and environmental pressure.

[0006] To address the aforementioned industry pain points, there is currently a lack of a modular wall system specifically designed for rental housing scenarios that enables non-destructive installation, rapid assembly and disassembly, high reusability, standardization, and sound insulation and moisture protection. Therefore, developing a quick-installation and quick-disassembly modular wall system and its installation method that adapts to the turnover characteristics of rental housing has become a pressing technical problem for those skilled in the art. Summary of the Invention

[0007] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a quick-installation and quick-disassembly modular wall system for rental housing and its installation method. It utilizes standardized modular panels combined with snap-fit ​​non-destructive connectors to achieve wet-free construction, drilling-free, adhesive-free, rapid assembly, and non-destructive disassembly. Both panels and connectors are reusable, adapting to the high-frequency turnover needs of rental housing. Simultaneously, it considers sound insulation, moisture resistance, aesthetics, and functional integration, significantly reducing decoration and renovation costs. This invention solves the problems of slow construction, significant disassembly damage, low reuse rate, poor environmental performance, and high maintenance costs associated with wall decoration in rental housing.

[0008] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a quick-installation and quick-removal modular wall system for rental housing, comprising modular wall units, top limiting connectors, bottom supporting connectors, side splicing buckles, vertically adjustable support feet, wall leveling pads, and functional integrated modules; all components are produced using standardized prefabrication, with no on-site cutting, no wet work, and no destructive fixing, and assembly is achieved through pure snap-fit ​​and support methods, without damaging the main building structure throughout the process.

[0009] Furthermore, the modular wall unit is a standardized rectangular prefabricated panel with a composite sandwich structure, including an outer decorative panel, an inner substrate, and a middle sound-insulating and moisture-proof core layer. The outer decorative panel is made of environmentally friendly fire-resistant material, with a pre-formed surface that requires no secondary painting, and its color and texture match the unified decoration style of rental housing. The inner substrate is made of high-strength lightweight calcium silicate board to ensure structural strength and resistance to deformation. The middle sound-insulating and moisture-proof core layer is made of high-density rock wool or environmentally friendly sound-insulating foam, which has sound insulation, heat insulation, and moisture-proof functions, meeting the dual needs of interior partition walls and decorative walls. The modular wall unit has a uniformly set standard width, and the height is divided into standard floor height and adjustable versions. The sides and top and bottom are pre-formed with snap-fit ​​slots, eliminating the need for on-site processing.

[0010] Furthermore, the top limiting connector is made of lightweight aluminum alloy profile, with an overall L-shaped inverted structure. One end is attached to the bottom surface of the top floor slab with a non-marking anti-slip pad, without drilling, nailing, or gluing. It is fixed by top compression and lateral force of the wall. The other end has a limiting slot for engaging the top of the modular wall unit, limiting the vertical displacement and back-and-forth sway of the wall. The length of the connector matches the width of the modular wall unit, and it is segmented for easy disassembly, assembly, and transportation.

[0011] Furthermore, the bottom support connector is an anti-slip support profile made of rigid PVC or aluminum alloy. It has an anti-slip rubber pad on the bottom, which can directly adhere to the ground without damaging the floor tiles, flooring, or cement base. The top has a support groove for supporting the bottom of the modular wall unit. The inner side of the support groove has an elastic shock-absorbing pad, which can both fix the bottom of the wall and buffer the force to prevent the board from being damaged by bumps. The height of the bottom support connector is adjustable to accommodate slight differences in ground level and achieve overall wall leveling.

[0012] Furthermore, the side splicing buckle is a built-in elastic buckle, pre-installed in the side groove of the modular wall unit. One side is a male buckle and the other side is a female buckle. When two adjacent modular wall units are spliced, the male and female buckles automatically engage, resulting in a uniform and tight splicing gap. No additional glue is required for sealing. The engaging force is moderate, and it can be disassembled by hand or with the help of simple tools, ensuring the splicing firmness and disassembly. The splicing buckle has a built-in sealing strip, which improves the overall sealing and sound insulation of the wall.

[0013] Furthermore, the vertically adjustable support feet are threaded adjustable support components, and there are multiple of them, symmetrically arranged on the back of the modular wall unit with evenly distributed vertical spacing. The ends of the support feet are equipped with flexible anti-slip pads to press against the original wall or building structure base. By rotating to adjust the support length, the verticality of the wall can be precisely adjusted, and the overall stability of the wall can be enhanced to prevent the wall from tilting or shaking. The support feet are not drilled or fixed throughout the entire process, but only used for pressing and supporting, and there are no traces after disassembly.

[0014] Furthermore, the wall leveling pad is an environmentally friendly hard rubber or lightweight plastic pad with various thicknesses. It is placed between the top limiting connector, the bottom supporting connector and the building base, adapting to the flatness deviation of the top surface, ground and original wall surface. No on-site plastering is required, and the overall horizontal and vertical of the wall surface can be quickly achieved, ensuring the flatness of the wall installation.

[0015] Furthermore, the functional integration module is a prefabricated modular component, including a socket module, a network cable interface module, a storage recess module, and a conduit concealment groove module. All of them adopt a snap-fit ​​installation and are directly embedded into the standard interface reserved in the modular wall unit. There is no need for on-site groove cutting and wiring. They can be easily replaced, disassembled, and moved later to meet the daily functional needs of rental housing such as electricity, network cable, and storage. The functional module is flush with the wall unit, which is beautiful and neat.

[0016] The installation method for a quick-installation and quick-removal modular wall panel system for rental housing includes the following steps: S1. On-site survey and base layer pretreatment: Survey the flatness, verticality and dimensions of the ceiling, floor and original walls of the installation area in the rental housing; clean up debris and dust on the floor and ceiling; no wet work such as plastering, leveling and drilling is required; for minor local height differences, match the wall leveling blocks of the corresponding thickness in advance; check the specifications and quantity of modular wall units and connectors to ensure that they match the on-site dimensions; all components are factory prefabricated standardized parts, and no on-site cutting and processing is required.

[0017] S2. Installation of Top Limiting Connector: According to the wall installation positioning line, attach the top limiting connector to the bottom surface of the ceiling slab. Place a wall leveling pad of the corresponding thickness between the connector and the ceiling surface, adjust the level of the connector, and temporarily fix it by relying on the connector's own inverted structure and anti-slip pad. No nails, expansion bolts, or adhesives are used throughout the process, and the ceiling structure is not damaged. Install the top limiting connector in sections, ensuring that the connector slots face downwards and are on the same horizontal line.

[0018] S3. Bottom Support Connector Installation: Lay the bottom support connector on the ground corresponding to the position of the top limiting connector. Insert anti-slip pads and leveling blocks into the bottom of the connector. Adjust the level and height of the support connector to ensure that the top support slot and the top limiting slot are aligned vertically to form a vertical installation channel. The bottom support connector is placed directly on the ground without fixing or damaging the floor decoration layer. It is suitable for various floor types such as wood flooring, tiles, and cement floors.

[0019] S4. Modular Wall Unit Assembly and Vertical Installation: Take the first modular wall unit, insert the top end into the limiting slot of the top limiting connector, and slowly lower the bottom end into the supporting slot of the bottom supporting connector to adjust the verticality of the wall. Then install the second modular wall unit, which is connected to the first unit through the built-in splicing buckle on the side. The horizontal assembly of the entire wall is completed in sequence. The built-in sealing strip at the splice joint automatically seals the gap, ensuring that the gap is uniform and tight. No fasteners are required during the assembly process, and the insertion operation can be completed by hand. It can be operated quickly by a single person.

[0020] S5. Verticality Adjustment and Stability Reinforcement: After the modular wall unit is assembled, adjust the vertically adjustable support feet on the back one by one. Rotate the support feet so that the flexible pads at their ends press firmly against the original wall or structural base, precisely adjusting the overall verticality and flatness of the wall to ensure that the wall is not tilted or wobbled. The support feet are tightened with moderate force, which ensures the stability of the wall and avoids damaging the base structure. After adjustment, the wall is solid and can be used directly as a partition wall or decorative wall.

[0021] S6. Functional Integration Module Installation: Align the prefabricated socket modules, network cable modules, storage modules, and other functional integration modules with the standard interfaces reserved in the modular wall unit, and directly snap them into place for quick and easy installation. Conceal the pipelines in advance in the gap between the back of the wall unit and the original wall, or embed them into the built-in pipeline groove of the modular wall unit. No on-site trenching and wiring are required, the pipeline layout is neat, and the later maintenance is convenient.

[0022] S7. Acceptance and Cleaning: Check the overall flatness, verticality, joint gaps and firmness of the wall surface, confirm that all connectors and functional modules are installed in place, clean up packaging waste on site. No cleaning or repair work is required. It can be put into use immediately after installation. There is no release of harmful gases and no need for ventilation.

[0023] S8. Non-destructive disassembly and reuse steps: When a rental property needs renovation, layout adjustment, or restoration after lease termination, first disassemble the integrated functional modules by simply pulling out the clips; then rotate the vertically adjustable support legs in the opposite direction to detach them from the original wall; starting from one end of the wall, use a special disassembly pry tool inserted into the gap of the side splicing clips to gently pry open the unlocking clips, and then separate each modular wall unit horizontally in sequence, removing the top of the wall unit from the top limiting slot and the bottom from the bottom supporting slot; finally, remove the top limiting connector and the bottom supporting connector. All panels and connectors are undamaged and undeformed, and can be directly transported to other properties for reuse. After disassembly, the main structure of the building has no holes, damage, or glue residue, completely restoring the original condition of the house.
