[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

Among them, the wall module 1 is innovatively connected by double memory alloy connectors to realize quick fixing and disassembly, avoiding the problems of misalignment, poor fixation, slow installation and disassembly, and difficult installation and disassembly of adjacent wall modules 1 caused by traditional fasteners. The decoration module integrates old-age health monitoring and auxiliary function components, and the functional module adopts single material design to consider environmental protection and performance. Each module is produced by standardized prefabrication, with 600mm×1200mm as the standard, and cooperates with three-point universal interface to realize efficient installation and flexible function expansion.

Then, the specific implementation of the core module is described: (1) Keel module: the keel module is used as the basic support structure of the wall, and high-strength 6061-T6 aluminum alloy material is selected, with a tensile strength of 260MPa, to ensure that the wall has good load-bearing performance. In the construction of the corridor and room partition wall of a certain floor in the old-age community, the size of the keel module is customized to 600mm×2400mm×20mm.

[0024] The installation steps are as follows: the construction personnel measures and positions the main wall surface of the building using a laser level, to ensure that the perpendicularity and levelness error of the keel module installation is controlled within 2 mm. M8x100 expansion bolts are used to fix the keel module to the wall surface, and the spacing between adjacent keel modules is strictly set according to the 600 mm standard, to form a regular support frame. A fixing groove with a depth of 15 mm and a width of 20 mm is reserved on the surface of the keel module for installing the decorative module and the functional module, to facilitate the accurate butt joint of the subsequent modules.

[0025] (ii) Cooperation of wall module 1 and double memory alloy connecting piece: wall module 1 is the key component to realize the connection and disassembly function of the wall, and its unique structure design is closely matched with the double memory alloy connecting piece.

[0026] Specifically, the wall module 1 is provided with a first storage groove 2 on one side, with a depth of 30 mm and a width of 40 mm, for accommodating the double memory alloy connecting piece; and on the other side, a pin slot 3 and a recycling groove 4 are distributed from top to bottom, with a depth of 25 mm and a width of 15 mm for the pin slot 3, and a depth of 40 mm and a width of 50 mm for the recycling groove 4, and both of them are in communication with the first storage groove 2. A disc-shaped limiting block 12 is fixed in the first storage groove 2, with a diameter of 30 mm and a thickness of 10 mm, and the outer arc wall thereof is used to limit the first memory spring 5, and the outer wall support protrusion has a height of 5 mm, which is used to support the second memory spring 6.

[0027] The structure of the double memory alloy connecting piece is as follows: it includes a first memory spring 5, a second memory spring 6, a connecting plate 7, a memory corrugated plate 8, and a fixed pin 9. The first memory spring 5 and the second memory spring 6 are both made of Ni-Ti memory alloy, with a phase transition temperature of 75±2℃; the memory corrugated plate 8 is also made of Ni-Ti alloy material; the fixed pin 9 has a length of 40 mm and a diameter of 8 mm, and the end close to the pin slot 3 is processed into an arc structure with an arc matching the inner wall of the pin slot 3.

[0028] The connection and disassembly process is described as follows: Connection operation: when installing the partition wall between the activity room and the rest area in the elderly community, the construction personnel aligns the adjacent wall modules 1, at which time the residual magnetism of the permanent magnet 10 on the side wall of the wall module 1 is automatically attracted, achieving preliminary positioning. A high-frequency electromagnetic induction heater with a power of 800 W and a frequency of 20 kHz is used to heat the memory corrugated plate 8, and the temperature rises to 75℃ within 12 seconds, the memory corrugated plate 8 changes from the initial wavy state to the horizontal state, pushing the fixed pin 9 to slide along the pin slot 3 and insert, completing the connection, and the single connecting piece has a pullout resistance of 650 N, meeting the use requirements of the elderly building; it should be noted that the high-frequency electromagnetic induction heater will not cause damage to the wall module 1, and has no effect on the work of other components.

[0029] Disassembly operation: when the community needs to adjust the space layout in the later period, use high-frequency electromagnetic induction heater to heat the first memory spring 5 and the second memory spring 6, the temperature reaches 75℃ within 15 seconds, the spring shrinks and separates from the limiting block 12. At this time, the fixed pin 9 is first inclined and falls along the transition section of the pin groove 3 under the action of gravity, the transition section is at an angle of 15° with the horizontal plane, and then it is separated from the pin groove 3 and falls into the recycling groove 4. At the same time, the reverse electromagnetic coil generates a reverse magnetic field to eliminate the adsorption force of the permanent magnet 10, and the wall module 1 is easily separated.

[0030] (Three) Functional module: the functional module is designed with single material for the special needs of the elderly community, which has environmental protection and functionality. For example, the heat and sound insulation functional module is made of polypropylene composite material, with a size of 600mm x 1200mm x 50mm.

[0031] It can be known that: the module edge is processed with T-shaped mortise and tenon structure and barb tooth structure, the T-shaped mortise and tenon tenon head is 20mm wide and 10mm thick; the barb tooth pitch is 2mm and the angle is 60°. During installation, the construction personnel align the functional module with the corresponding interface on the wall module 1, and press axially to make the barb tooth self-locking, so that the connection is firm.

[0032] The module joint is embedded with rubber magnetic strip, model CR-08, residual magnetism 0.15T, width 15mm, thickness 5mm, forming a magnetic force sealing layer, the air tightness meets the standard, effectively blocking noise and cold and hot air exchange.

[0033] The module surface is coated with a biological-based antibacterial coating with a thickness of 0.1mm, which has a high antibacterial rate for E. coli and S. aureus, creating a healthy living environment for the elderly.

[0034] When the functional module reaches the service life, it can be directly sent to the recycling factory for crushing treatment, the material is recycled, the particle size of the regenerated particles is controlled within 3mm, which is used to produce new functional modules, realizing resource recycling.

[0035] (Four) Age-friendly function of decorative module: the decorative module in the elderly community not only beautifies the environment, but also ensures safety, with a millimeter wave radar monitoring unit and an adjustable handrail inside.

[0036] Millimeter wave radar monitoring unit installation: when installing the wall decoration module in the old man's bedroom, a millimeter wave radar monitoring unit with a working frequency of 24 GHz, model SRR24-Pro, is embedded in the keel module, 50 mm away from the surface of the decorative panel. Through the reserved 35 mm diameter circular hole in the decorative module, the radar monitoring unit is fixed on the special bracket. The unit can penetrate the decorative panel to achieve non-contact monitoring of the old man's breathing rate, heart rate, and fall status, with a breathing rate monitoring accuracy of ±0.3 times / minute and a heart rate monitoring accuracy of ±1 times / minute. When an abnormality is detected, the system sends an alarm message to the community monitoring center and the old man's family mobile phone APP within 5 seconds through the Zigbee protocol.

[0037] Adjustable handrail installation: the adjustable handrail is made of lightweight high-strength aluminum alloy material, wrapped with a non-slip rubber layer, hidden in the groove at the bottom of the decorative module, with dimensions of 1200 mm x 30 mm x 30 mm. During the wall decoration in the bathroom, the construction personnel connect the handrail to the wall through spring buckles, with a spring buckle unlocking force of 12 N. The old man can adjust the height of the handrail within the range of 800-1200 mm through the electric knob, and the handrail is at an angle of 90° with the wall surface after unfolding, capable of bearing 160 kg. The surface pressure sensor of the handrail monitors the pressure in real time, and when the continuous pressure is ≥30 N and lasts for 3 minutes, an overtime alarm is triggered to remind the nursing staff to pay attention to the old man's condition.

[0038] III. Standardization and general interface design arrangement The size of all modules is standardized at 600 mm x 1200 mm, with a three-contact general interface at the back.

[0039] Mechanical contact: using buckle design, the male buckle and female buckle have a plug-in life of 1200 times. During the installation of the corridor wall decoration module and functional module, the construction personnel align the back of the module, the male buckle automatically clicks into the female buckle, achieving mechanical fixation.

[0040] Power contact: using spring needle connectors, which can support current transmission below 10 A. When installing the thermal insulation module with heating function, the power contact automatically connects with the power bus bar in the keel module, providing power for the 80 W / m 2 graphene heating film, ensuring indoor warmth in winter.

[0041] Data contact: using NFC chip, model NTAG213, to achieve automatic module identification. When installing the projection functional module in the multi-functional hall wall, after the module back NFC chip contacts the keel module data contact, the central control system automatically identifies the module type, adjusts the indoor light, and lowers the projection curtain, achieving intelligent scene switching.

[0042] IV. System installation full process example Taking the overall decoration of a unit floor in a retirement community as an example, the system installation process is as follows: Keel module construction: the construction team uses laser level and expansion bolts to fix the keel module on the main wall of the building according to the design drawings, forming a standard 600mm*600mm grid support structure.

[0043] Wall module 1 connection: sequentially splice wall module 1, pre-position using permanent magnet 10, then complete the fixation between wall modules 1 by heating memory corrugated board 8 through high-frequency electromagnetic induction, and build a complete wall frame.

[0044] Functional module installation: according to the functional requirements of each room, install the corresponding functional module, such as installing thermal and sound insulation modules in the bedroom and installing moisture-resistant and antibacterial modules in the bathroom, quickly connect them with wall module 1 through T-shaped mortise and tenon structure and barb tooth structure, and seal them with rubber magnetic strips.

[0045] Decorative module installation: connect the decorative module integrated with millimeter wave radar monitoring unit and adjustable handrail with wall module 1 and keel module through three-contact universal interface to ensure normal electrical connection and data transmission, and complete the appearance decoration at the same time.

[0046] In summary, in the present application, the double memory alloy connection method is different from the traditional building wall connection method. The double memory alloy connecting piece of the present application realizes the convenient operation of "heating connection-reheating disassembly". In the decoration of the retirement community, compared with the bolt connection, the efficiency is improved, and the problems such as misalignment, insecure fixation, slow installation and disassembly, and difficult installation and disassembly of traditional fasteners in adjacent wall modules 1 are avoided, the connection is stable, and the long-term use requirements of the retirement building are met.

The integrated design of millimeter wave radar monitoring and adjustable handrail provides safety protection for the elderly, real-time health monitoring and emergency alarm functions, effectively reducing the risk of accidents for the elderly; the adjustable handrail meets the use needs of the elderly with different physical conditions, and embodies the humanized care. The standard module and universal interface design make the decoration of the retirement community "plug and play", facilitating the functional upgrade and module replacement in the later period; the intelligent control of NFC data contact improves the community management efficiency and provides technical support for smart retirement.

[0047] The modular and detachable building wall decoration system of the present application has significant practicality and reliability in the scene of the retirement community, effectively solves many problems existing in the traditional retirement building decoration, and has broad application prospect and social and economic benefits.
