Description

Technical Field

[0001] This invention relates to the field of building wall technology, specifically to a multifunctional prefabricated building wall. Background Technology

[0002] Walls are essential components in buildings, serving load-bearing, enclosing, and dividing spaces. They also provide thermal insulation and sound insulation. In interior spaces, aside from the necessary load-bearing walls, other walls primarily serve to divide the interior into different spaces to achieve various functions.

[0003] Current apartment layouts often feature a large, open-plan living room combined with a study. Due to size limitations, dividing the living room into fixed rooms makes it feel cramped, while leaving it undivided results in limited functionality and inefficient space utilization. Even in studio apartments, different functional needs arise during the day and night. During the day, a larger open space is needed, while at night more privacy is required. Therefore, movable partitions, sliding partitions, and screens are commonly used. However, movable and sliding partitions only expand the view between the two rooms; the use of each space remains fixed, still failing to effectively utilize the space. Screens, on the other hand, offer poor privacy, stability, and sound insulation, and their fixed design cannot be matched to different interior design styles.

[0004] Therefore, the research objective of this invention is to design a multifunctional prefabricated building wall that can be freely moved to adjust the usable space of two rooms while effectively ensuring the stability of the wall and the sound insulation of the space. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a multifunctional prefabricated building wall that can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this invention is: A multifunctional prefabricated building wall, comprising: The supporting base is fixedly installed on the building foundation to form a corresponding bottom elevated layer; The floor mechanism is composed of multiple prefabricated panels spliced ​​and installed on the support base, and the floor mechanism is provided with at least two parallel guide grooves that extend to the building foundation surface; A movable partition wall is movably installed on the floor mechanism along the guide groove to adjust the size of the space area on both sides of it; A drive mechanism, corresponding to the guide groove, is disposed on the movable partition wall and located within the bottom open layer, for driving the movable partition wall to move along the guide groove. The main locking mechanism has a guide rail fixedly installed on the building foundation surface at a position corresponding to the guide groove. The main locking mechanism includes an electromagnetic actuator installed on the driving mechanism and a locking part installed on the guide rail. The electromagnetic actuator is driven to move and embed into the locking part by being energized and magnetized to lock the movable partition wall. It is released to unlock after the power is cut off. A slot compensation mechanism is provided corresponding to the guide slot, and is used to dynamically fill or cover guide slots of different sizes formed by the movement of the movable partition wall when the movable partition wall moves. An auxiliary locking mechanism is linked to and moves synchronously with the main locking mechanism. When the main locking mechanism brakes, it drives the auxiliary locking mechanism to lock the main locking mechanism synchronously.

[0007] The slot compensation mechanism includes two rigid belts fixed on both sides of the drive mechanism. The rigid belts are laid on the guide groove and their ends can be wound up. When the movable partition moves along the guide groove, the two rigid belts are wound up and spread up synchronously with the movable partition.

[0008] The precast slabs located on both sides of the guide groove have stepped sides. The rigid belt is laid on the steps of the guide groove, and its upper surface is flush with the upper surface of the floor mechanism. The groove compensation mechanism also includes rollers that are driven to rotate at both ends of the building foundation surface by corresponding motors. The end of the rigid belt that is not connected to the drive mechanism is fixed to the roller. When the rigid belt is wound up, the roller is driven to rotate by the motor. A connecting block is fixed on the outer side of the roller on the building foundation surface. The top of the connecting block is set as an I-shaped structure that matches the steps of the precast slab, and is used to fill the end of the guide groove.

[0009] The drive mechanism includes a mounting base that is fixedly installed at the bottom of the movable partition wall via a connecting plate embedded in the guide groove. The mounting base has several cavities spaced apart, and a drive wheel adapted to the guide rail is rotatably installed in each cavity.

[0010] The engaging part consists of numerous protrusions evenly distributed in the middle of the guide rail; the electromagnetic actuator is an electromagnet fixedly installed in the middle cavity of the mounting base, and a magnetic metal part is mounted on the electromagnet by means of an elastic element that moves up and down; a brake rod fixed on the magnetic metal part is moved through the electromagnet; the elastic element is sleeved on the outside of the brake rod and its two ends are respectively fixed on the magnetic metal part and the electromagnet.

[0011] The auxiliary locking mechanism includes a movable frame fixedly mounted on the magnetic metal component. Metal rods are movable on both sides of the movable frame via corresponding springs. A corresponding groove is recessed inward at the center of the drive wheel, and a permanent magnet is fixedly mounted within the groove. When the electromagnet is de-energized, the metal rod is outside the magnetic attraction range of the permanent magnet, meaning the spring force is greater than the magnetic attraction force of the permanent magnet on the metal rod. After the movable frame moves down to its position, the magnetic attraction force of the permanent magnet on the metal rod is greater than the spring force. When the electromagnet is energized, it drives the magnetic metal component to move down and causes the brake rod to move down and insert into two adjacent locking teeth. The permanent magnet attracts the metal rod, causing it to extend and abut against the groove.

[0012] The two side plates of the central cavity of the mounting base are provided with elongated holes connecting the two side cavities or embedded grooves extending to the top, and the end of the metal rod facing the elongated hole is provided with an arc-shaped structure concentric with the permanent magnet.

[0013] The movable partition wall is a non-magnetic lightweight steel welded wall frame. The outer side of the wall frame is fixed with corresponding isolation wooden wall panels, and the wall frame located between the isolation wooden wall panels can be filled with corresponding sound insulation material.

[0014] A wall-mounted folding bed can be stored and installed on the bedroom side of the wall frame. The wall-mounted folding bed is embedded in the wall frame when stored and can move with the movable partition wall.

[0015] The support base includes a plurality of support components fixed at intervals to the building foundation surface, and an isolation support plate laid and fixed on the support components. The floor mechanism is laid on the isolation support plate. The support component includes a support base fixed to the building foundation surface by bolts. A support rod is fixedly installed on the support base in an adjustable manner by means of threaded connection. A support block is fixedly installed horizontally on the top of the support rod.

[0016] Advantages of this invention: 1) This invention uses a hidden drive mechanism installed in the bottom elevated layer to support and drive the movable partition wall. It uses electromagnetic drive combined with mechanical locking to brake and lock, and automatically adapts to fill the guide groove by rolling and unrolling. Then, the auxiliary locking drive wheel is automatically locked by the action of the main locking mechanism. This allows for the setting of a movable wall structure while ensuring stability and sound insulation. The wall mechanism can be moved freely as needed to adjust the usable space of two adjacent rooms, effectively improving the space utilization rate.

[0017] 2) The present invention provides a stable support plane for the floor mechanism by setting a support base, and can form a bottom open layer that facilitates the concealment and installation of the drive mechanism. The movable partition and the drive mechanism are respectively installed on the floor mechanism and in the bottom open layer, which can ensure the stability of the movable partition installation and movement, and improve the sound insulation effect by improving the connection between the movable partition and the building foundation surface.

[0018] However, because the drive mechanism is located in the bottom elevated layer, which is not easy to disassemble, the movable partition is not easy to fix after it moves, which affects the user experience and safety. Therefore, this invention adds a main locking mechanism to the drive mechanism, which is a combination of electromagnetic brake and mechanical locking. The electromagnet is energized to move the magnetically attracted metal parts downward, which in turn drives the brake rod fixed on the magnetically attracted metal parts to move downward and embed into the two adjacent locking teeth on the guide rail, thereby quickly locking the movable partition and ensuring its stability.

[0019] 3) This invention adds an auxiliary locking mechanism to the main locking mechanism, providing double insurance for the braking and fixing of the movable partition wall, making the braking process more reliable and safer. The auxiliary locking mechanism is passively triggered by the action of the main locking mechanism. Utilizing a "one-move-all" linkage design, it ensures that the drive wheels are automatically locked at the same time as the main braking takes effect, preventing any slight movement caused by inertia or external force. This greatly improves braking reliability and safety. Furthermore, the linkage design simplifies the control system, eliminating the need for a separate drive circuit for the auxiliary braking.

[0020] When an electromagnet is energized, it moves the moving frame downwards, placing the metal rod installed within the frame within the magnetic attraction range of a permanent magnet. The magnetic force of the permanent magnet on the metal rod is greater than the spring force, causing the metal rod to extend and automatically lock the drive wheel, improving braking safety. Upon unlocking, the electromagnet is de-energized, and the elastic potential energy of the elastic element causes the brake lever and moving frame to move upwards and reset, causing the metal rod to move upwards and disengage from the permanent magnet's magnetic range, thus unlocking the drive wheel.

[0021] 4) Because the movable partition is installed via a drive mechanism and a supporting base, gaps such as guide grooves will form on the floor. Furthermore, the lengths of the guide grooves on both sides of the movable partition change as it moves. If these different lengths of guide grooves are not properly filled or covered, problems can arise. Therefore, this invention further incorporates a groove compensation mechanism on both sides of the movable wall to dynamically fill or cover the guide grooves of varying sizes formed during the movement of the movable partition. As the movable partition moves, the groove compensation mechanism automatically adapts to different positions of the movable wall through a retracting and rolling action, dynamically filling the guide grooves and ensuring they are always covered. This effectively prevents debris particles from falling into the bottom raised floor and affecting the use of the movable partition, maintaining a flat and aesthetically pleasing building foundation surface, and ensuring the practical effectiveness of this invention.

[0022] Traditionally, flexible or segmented cover plates are used to cover the guide groove, and their fixed size restricts the movement of the movable partition. In contrast, the groove compensation mechanism of this invention is a rigid flat strip fixed to the movable partition. Its hardness is sufficient to provide support strength, and it can be smoothly extended and retracted. Furthermore, it can be wound up by using a motor to drive the roller, which not only achieves synchronous movement and covering, improving the degree of automation, but also improves the flexibility of the movable wall movement.

[0023] 5) This invention employs adjustable and fixed installation support rods to adapt to uneven building foundation surfaces, ensuring the flatness of the floor structure. Furthermore, the support components and isolation support plates elevate the floor structure, providing effective moisture protection. More importantly, it provides a raised bottom layer for the installation of movable partitions. The movable partition of this invention can be constructed from a lightweight welded steel wall frame. The outer surface of the wall frame is fixed with isolation wooden wall panels and filled with sound insulation material. This not only reduces the weight of the wall for easy movement but also ensures effective sound insulation. Additionally, space can be reserved on the wall frame to install a folding bed that can be stored on the wall. This allows the movable partition to move more freely, maximizing the expansion space of adjacent rooms. Attached Figure Description

[0037] To facilitate understanding by those skilled in the art, the structure of the present invention will now be described in further detail with reference to the accompanying drawings: Example 1 refer to Figure 1-11 A multifunctional prefabricated building wall, comprising: Support base 1 is fixedly installed on the building foundation surface 2 to form a corresponding bottom elevated layer; The floor mechanism 3 is assembled from multiple prefabricated panels on the support base 1. The floor mechanism 3 is provided with at least two parallel guide grooves 301 that extend to the building foundation surface 2. The movable partition 4 is movably installed on the floor mechanism 3 along the guide groove 301 to adjust the size of the space area on both sides of it; The driving mechanism 5 is disposed on the movable partition wall 4 corresponding to the guide groove 301 and located in the bottom open layer, and is used to drive the movable partition wall 4 to move along the guide groove 301; The main locking mechanism 6 has a guide rail 12 fixedly installed on the building foundation surface 2 corresponding to the guide groove 301. The main locking mechanism 6 includes an electromagnetic actuator installed on the drive mechanism 5 and a locking part installed on the guide rail 12. The electromagnetic actuator is driven to move and embed into the locking part by being energized and magnetized to lock the movable partition wall 4. It is released after the power is cut off to unlock. The slot compensation mechanism 7 is provided in correspondence with the guide slot 301 and is used to dynamically fill or cover the guide slots 301 of different sizes formed by the movement of the movable partition wall 4 when the movable partition wall 4 moves. The auxiliary locking mechanism 8 is linked to the main locking mechanism 6 and moves synchronously with it. When the main locking mechanism 6 brakes, it drives the auxiliary locking mechanism 8 to lock the main locking mechanism 6 synchronously.

[0038] This invention utilizes a hidden drive mechanism 5 installed in the bottom elevated layer to support, fix, and drive the movable partition wall 4. It employs electromagnetic drive combined with mechanical locking for braking and locking, and automatically adapts to fill the guide groove 301 using a rolling and unrolling mechanism. Furthermore, the main locking mechanism 6 triggers the automatic locking of the auxiliary locking drive wheel 502. This design ensures stability and sound insulation while providing a movable wall structure. The wall mechanism can be freely moved as needed to adjust the usable space of two adjacent rooms, effectively improving space utilization.

[0039] The slot compensation mechanism 7 includes two rigid belts 701 fixed on both sides of the drive mechanism 5. The rigid belts 701 are laid on the guide groove 301 and their ends can be wound up. When the movable partition 4 moves along the guide groove 301, the two rigid belts 701 are wound up and spread up synchronously with the movable partition 4.

[0040] The precast panels located on both sides of the guide groove 301 have stepped sides. The rigid belt 701 is laid on the steps of the guide groove 301, and its upper surface is flush with the upper surface of the floor mechanism 3. The groove compensation mechanism 7 also includes rollers 703 that are driven to rotate at both ends of the building foundation surface 2 by corresponding motors 702. The end of the rigid belt 701 that is not connected to the drive mechanism 5 is fixed to the roller 703. When the rigid belt 701 is wound up, the roller 703 is driven to rotate by the motor 702. A connecting block 704 is fixed on the outer side of the roller 703 on the building foundation surface 2. The top of the connecting block 704 is set as an I-shaped structure that matches the steps of the precast panels, and is used to fill the end of the guide groove 301.

[0041] Because the movable partition 4 is installed via the drive mechanism 5 in conjunction with the support base 1, corresponding gaps such as guide grooves 301 will be formed on the floor. Furthermore, the lengths of the guide grooves 301 on both sides of the movable partition 4 change as the partition 4 moves. If the guide grooves 301 of different lengths are not properly filled or covered, this can lead to problems. Therefore, this invention further adds a groove compensation mechanism 7 to both sides of the movable wall to dynamically fill or cover the guide grooves 301 of different sizes formed by the movement of the movable partition 4. As the movable partition 4 moves, the groove compensation mechanism 7 automatically adapts to different positions of the movable wall through a retracting and rolling action, dynamically filling the guide grooves 301 and always ensuring coverage. This effectively prevents garbage particles from falling into the bottom raised floor and affecting the use of the movable partition 4, maintaining the flatness and aesthetics of the building foundation surface 2, and ensuring the practical effect of this invention.

[0042] Traditionally, flexible or segmented cover plates are used to cover the guide groove 301. Their fixed size restricts the movement of the movable partition wall 4. In contrast, the groove compensation mechanism 7 of the present invention is a rigid belt 701 fixed on the movable partition wall 4. Its hardness is sufficient to provide support strength, and it can achieve smooth opening and closing. Then, the roller 703 can be driven by the motor 702 to rewind, which not only realizes the synchronization of movement and covering, improves the degree of automation, but also improves the flexibility of the movable wall movement.

[0043] The drive mechanism 5 includes a mounting base 501 fixedly installed at the bottom of the movable partition wall 4 via a connecting plate 9 embedded in the guide groove 301. The mounting base 501 has several cavities spaced apart, and a drive wheel 502 adapted to the guide rail 12 is rotatably installed in the cavity. The movable partition wall 4 can be manually pushed or a drive motor connected to the drive wheel 502 can be installed on the movable partition wall 4.

[0044] The engaging part consists of numerous protrusions evenly distributed in the middle of the guide rail 12, forming locking teeth 601; the electromagnetic actuator is an electromagnet 602 fixedly installed in the middle cavity of the mounting base 501, and a magnetic metal part 604 is mounted on the electromagnet 602 via an elastic element 603 that moves up and down; a brake rod 605 is movably and penetratingly disposed on the electromagnet 602 and fixed on the magnetic metal part 604; the elastic element 603 is sleeved on the outside of the brake rod 605 and its two ends are respectively fixed on the magnetic metal part 604 and the electromagnet 602; a corresponding power supply module can be detachably installed on the movable partition 4, and the power supply module is connected to the battery patch 602 via corresponding wires; the power supply module can be a lithium battery or a storage battery.

[0045] The present invention provides a stable support plane for the wooden base plate by setting the support base 1, and can form a bottom open layer for easy concealment and installation of the drive mechanism 5. The movable partition wall 4 and the drive mechanism 5 are respectively installed in the floor mechanism 3 and the bottom open layer, which can ensure the stability of the installation and movement of the movable partition wall 4, and improve the sound insulation effect by improving the connection between the movable partition wall 4 and the building foundation surface 2.

[0046] However, because the drive mechanism 5 is located in the bottom open layer that is not easy to disassemble, the movable partition 4 is not easy to fix after it moves, which affects the user experience and safety. Therefore, the present invention adds a main locking mechanism 6 to the drive mechanism 5, which is a combination of electromagnetic brake and mechanical locking. When the electromagnet 602 is energized, it moves the magnetically attracted metal part 604 downward, which in turn drives the brake rod 605 fixed on the magnetically attracted metal part to move downward and embed into the two adjacent locking teeth 601 on the guide rail 11, thereby quickly locking the movable partition 4 and ensuring its stability.

[0047] The auxiliary locking mechanism 8 includes a movable frame 801 fixedly mounted on the magnetic metal part 604. Metal rods 803 are movably mounted on both sides of the movable frame 801 via corresponding springs 802. A corresponding groove 5021 is recessed inward at the center of the drive wheel 502, and a permanent magnet 804 is fixedly mounted within the groove 5021. When the electromagnet 602 is de-energized, the spring force of the spring 802 is greater than the magnetic attraction force of the permanent magnet 804 on the metal rod 803. After the movable frame 801 moves down to its position, the magnetic attraction force of the permanent magnet 804 on the metal rod 803 is greater than the spring force of the spring 802. When the electromagnet 602 is energized, it drives the magnetic metal part 604 to move down and causes the brake rod 605 to move down and insert into two adjacent locking teeth 601. The permanent magnet 804 attracts the metal rod 803, causing it to extend and abut against the groove 5021.

[0048] The two side plates of the central cavity of the mounting base 501 are provided with elongated holes 5011 connecting the two side cavities or embedded grooves extending to the top. The end of the metal rod 803 facing the elongated hole 5011 is configured as an arc surface structure concentric with the permanent magnet 804.

[0049] This invention adds an auxiliary locking mechanism 8 to the main locking mechanism 6, providing double insurance for the braking and fixing of the movable partition wall 4, making the braking process more reliable and safer. The auxiliary locking mechanism 8 is passively triggered by the action of the main locking mechanism 6. Utilizing a "one-move-all" linkage design, it ensures that the drive wheel 502 is automatically locked at the same time as the main braking takes effect, preventing any slight movement caused by inertia or external force. This greatly improves braking reliability and safety, and the linkage design simplifies the control system, eliminating the need for a separate drive circuit for the auxiliary braking.

[0050] When the electromagnet 602 is energized, it causes the movable frame 801 to move downward, placing the metal rod 803 installed within the movable frame 801 within the magnetic attraction range of the permanent magnet 804. The magnetic attraction force of the permanent magnet 804 on the metal rod 803 is greater than the elastic force of the spring 802, thus attracting the metal rod 803 to extend and automatically locking the drive wheel 502, improving braking safety. Upon unlocking, the electromagnet 602 is de-energized, and under the elastic potential energy of the elastic element 603, the brake lever 605 and the movable frame 801 move upward and reset, causing the metal rod 803 to move upward and disengage from the magnetic attraction range of the permanent magnet 804, thereby unlocking the drive wheel 502.

[0051] The movable partition 4 is a non-magnetic lightweight steel welded wall frame 401. The outer side of the wall frame 401 is fixed with corresponding isolation wooden wall panels 402, and the wall frame 401 located between the isolation wooden wall panels 402 can be filled with corresponding sound insulation material. A corresponding wall folding bed 10 can be stored and installed on the wall frame 401 on the bedroom side. When stored, the wall folding bed 10 is embedded in the wall frame 401 and can move with the movable partition 4.

[0052] The movable partition 4 of the present invention can be constructed from a wall frame 401 made of lightweight steel welded together. The outer side of the wall frame 401 is filled with sound insulation after being fixed by the isolation wooden wall panel 402. This not only reduces the weight of the wall to facilitate movement, but also ensures effective sound insulation. In addition, space can be reserved on the wall frame 401 to install a folding bed 10 that can be stored on the wall. This allows the movable partition 4 to move more, thereby maximizing the expansion space of the adjacent room.

[0053] The support base 1 includes a plurality of support components 101 fixed at intervals on the building foundation surface 2, and an isolation support plate 102 laid and fixed on the support components 101. The floor mechanism 3 is laid on the isolation support plate 102. The support component 101 includes a support base 1011 fixed to the building foundation surface 2 by bolts. A support rod 1012 is fixedly installed on the support base 1011 by means of threaded connection. A support block 1013 is fixedly installed horizontally on the top of the support rod 1012.

[0054] The present invention uses an adjustable fixed installation support rod 1012 to adapt to the unevenness of the building foundation surface 2, ensuring the flatness of the floor mechanism 3, and uses the support component 101 and the isolation support plate 102 to raise the floor mechanism 3 to achieve an effective moisture-proof effect. More importantly, it provides a bottom raised layer for the installation of the movable partition wall 4.

[0055] Example 2 refer to Figure 12The difference between this embodiment and embodiment one is that: a rubber part 12 is embedded in the top of the wall frame 401 and is driven to move up and down by a corresponding power mechanism. After the movable partition 4 is moved into place, the rubber part 12 is driven to move up by the power mechanism to connect the gap between the movable partition 4 and the ceiling.

[0056] The bottom of the rubber component 12 is fixedly connected to a corresponding base 14. The power mechanism is a cam 13 rotatably mounted on the wall panel of the movable partition 4. The cam 13 is driven to rotate manually or electrically, so that its protruding part abuts against the base 14 and pushes the rubber component 12 outward from the wall frame 401 through the connection gap to ensure the sound insulation effect. Before the movable partition 4 moves, the rubber strip 12 moves downward with the rotation of the cam 13 under the action of gravity, so that the distance between the movable partition 4 and the ceiling is set. The power structure can also be other existing lifting drive mechanisms and is not limited to the above structure.

[0057] It should be noted that this embodiment is implemented in the same way as embodiment one in terms of principle and technical effect. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in embodiment one.

[0058] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
