Description

Technical Field

[0001] This application relates to the field of partition wall technology, and in particular to a prefabricated partition wall. Background Technology

[0002] Partition walls are a type of non-load-bearing wall, commonly used to divide space. To increase installation flexibility, prefabricated partition walls are now frequently used. Partition walls are made from a variety of materials, typically including aluminum alloy, composite panels, smart glass, or steel.

[0003] Among them, dimming glass is a functional laminated glass product made by sandwiching a liquid crystal film between two layers of glass and processing it under high temperature and pressure. The dimming glass can be controlled by voltage to change between a scattering state and a projection state, so that the partition wall can meet the dual requirements of glass transparency and privacy protection.

[0004] Smart glass is relatively expensive, making its installation and protection extremely important. Current technology typically uses a combination of smart glass and metal frames as partition walls. Smart glass partition walls are usually installed in upscale areas, such as office areas in high-end office buildings and VIP areas in high-speed rail stations. However, in scenarios with frequent vibrations, such as high-speed rail stations, the vibration force will be transmitted to the smart glass through the frame. With increased use, this will have a certain impact on the lifespan of the smart glass partition wall. Summary of the Invention

[0005] In order to reduce the impact of vibration on the service life of the dimming glass partition wall, this application provides a prefabricated partition wall.

[0006] This application provides a prefabricated partition wall with the following technical solution:

[0007] A prefabricated partition wall includes a fixed frame and a wall body, the wall body being installed within the fixed frame; the fixed frame includes a pair of side rails and a pair of frame strip assemblies, the pair of side rails being respectively disposed on the left and right sides of the wall body, the side rails being abutted against the vertical sidewalls of the wall body, and the pair of frame strip assemblies being respectively located on the upper and lower sides of the wall body; the frame strip assembly includes a channel strip, a first abutting roller, and a second abutting roller, the two ends of the channel strip being respectively connected to the ends of the side rails on both sides of the wall body; the channel strip includes a base plate and side plates disposed on both sides of the base plate, the base plate and the side plates on both sides of the base plate forming an installation cavity; the wall body has a main body and installation portions located on the upper and lower sides of the main body, the main body extending into the installation cavity, the installation portions being entirely located within the installation cavity, and the installation portions being positioned away from the wall body. The surface of the main body is defined as the abutment surface, which is arc-shaped. Two sets of first abutment rollers are provided, each set connected to a side plate on either side of the base plate, and abutting against two opposing surfaces of the main body. Each set of first abutment rollers includes multiple first abutment rollers, spaced apart along the height of the wall. Multiple second abutment rollers are provided, spaced apart along the circumference of the mounting portion, each connected to the inner wall of the grooved strip, and abutting against the abutment surface. Rubber sheets are wound around the periphery of both the first and second abutment rollers, with the surface of the rubber sheets abutting against the surface of the wall, and a clearance gap exists between the abutment surface and the base plate.

[0008] By adopting the above technical solution, firstly, a fixed frame is formed by the side guard strips and frame strips to fix the partition wall; secondly, two sets of first abutment rollers wrapped with rubber sheets clamp the main body of the wall, and two sets of second abutment rollers wrapped with rubber sheets support the wall by contact with the abutment surface, so that the wall is in a suspended state, thereby reducing the risk of the channel strip transmitting vibration force to the wall and causing the wall to crack; finally, since both the first and second abutment rollers abut against the wall through rubber sheets, the vibration force from the channel strip will be buffered by the rubber sheets during the process of being transmitted to the wall, which can reduce the rigid damage to the wall and thus effectively reduce the impact of vibration on the service life of the dimming glass partition wall.

[0009] Optionally, the second abutting roller is connected to the grooved strip via an elastic component, the elastic component including a fixed cylinder, a movable rod and a first spring; the fixed cylinder is connected to the grooved strip, one end of the movable rod is connected to the second abutting roller, and the other end passes through the fixed cylinder, the first spring is located inside the fixed cylinder, and the end of the first spring abuts against the end of the movable rod away from the second abutting roller.

[0010] By adopting the above technical solution, the distance between the second abutment roller and the base plate can be varied, so that the wall has a certain space to move up and down when vibration occurs. During the up and down movement of the wall, friction is generated between the wall and the rubber sheet on the first abutment roller, which consumes energy. At the same time, the first spring plays a buffering role on the movement of the wall, further reducing the rigid damage to the wall, thereby further reducing the risk of the wall being cracked by vibration. In addition, the spring has a long service life while having good support capacity.

[0011] Optionally, a second spring is provided in the clearance gap, with the two ends of the second spring abutting against the abutting surface and the base plate, respectively.

[0012] By adopting the above technical solution, the second spring further assists in supporting the wall. By adding the second spring, the use of the second abutment roller and elastic component is reduced, thereby lowering the manufacturing cost and further buffering the vertical movement of the wall.

[0013] Optionally, the plurality of second abutment rollers are divided into two groups, with the two groups of second abutment rollers located on both sides of the second spring respectively; both ends of the base plate have a first extension, and both ends of the side plate have a second extension, the first extension and the second extension forming a control cavity; the ends of the second abutment rollers are connected to gears, and a rack is provided in the control cavity, the rack being used to drive all the second abutment rollers in one group to rotate in the same direction; one side of the rack is provided with a first sliding member, and the other side is provided with a second sliding member; the end of the abutment surface is connected to a first guide member, the first guide member having a first guide groove, the first guide groove being used for the first sliding member to slide, the distance between the first guide groove and the second extension gradually increasing from the end closer to the first extension to the other end; a second guide member is provided in the control cavity, the rack being located between the second guide member and the first guide member, the second guide member having a second guide groove, the second guide groove being used for the second guide member to slide and connect, the second guide groove being coaxially arranged with the abutment surface.

[0014] By adopting the above technical solution, when the wall moves downward, it drives the first guide member to move downward. Under the guidance of the first guide groove, the first sliding member moves away from the second extension. The first sliding member drives the rack to move. The rack moves along the direction of the second guide groove under the constraint of the second sliding member and the second guide groove. During the movement of the rack, it drives the gear to rotate. At the contact position between the second abutting roller and the wall, the movement direction of the contact point between the second abutting roller and the wall is opposite to the movement direction of the wall. During the upward movement of the wall, the above actions are performed in reverse, so that during the upward and downward movement of the wall, relative friction is formed between the second abutting roller and the abutting surface, thereby consuming energy through friction between the wall and the second abutting roller, further improving the shock absorption effect on the wall.

[0015] Optionally, a set of first abutting rollers includes two first abutting rollers, and the rubber sheet of the two first abutting rollers in the same set is the same piece, and the portion of the rubber sheet located between the two first abutting rollers abuts against the surface of the wall.

[0016] By adopting the above technical solution, and by setting up a resistance-increasing part, the contact area between the rubber sheet of the first abutting roller in the same group and the wall is increased, thereby increasing the frictional resistance and further improving the clamping effect and shock absorption effect of the first abutting roller on the wall.

[0017] Optionally, the surface of the rubber sheet is provided with a plurality of protrusions, and the plurality of protrusions are evenly distributed on the surface of the rubber sheet.

[0018] By adopting the above technical solution, while the wall moves up and down, the first abutting roller rotates, thereby causing the rubber sheet to detach from one of the first abutting rollers and wrap around the other first abutting roller. That is, the rubber sheet will have relative movement with the first abutting roller. During this process, multiple protrusions intermittently pass between the first abutting roller and the wall, thereby causing the abutting force between the rubber sheet and the wall to intermittently increase, further increasing the frictional energy consumption during the up and down movement of the wall.

[0019] Optionally, the protrusion is disposed on the surface of the rubber sheet opposite to the wall.

[0020] By adopting the above technical solution, the wall always has a large contact area with the rubber sheet, ensuring frictional stability and the clamping stability of the first abutting roller on the wall.

[0021] Optionally, the side plate is provided with a connecting rod, and a limiting plate is provided at one end of the connecting rod away from the side plate. The limiting plate is located between the two first abutting rollers and abuts against the rubber sheet between the two first abutting rollers.

[0022] By adopting the above technical solution, the rubber sheet located between the two first abutting rollers is always in contact with the wall by the abutting of the limiting plate, so as to ensure that the resistance-increasing part has a large abutting force and friction force on the wall.

[0023] Optionally, the first abutting roller is connected to the side plate via a support rod, the support rod including a fixed part and a rotating part, one end of the fixed part being connected to the first abutting roller, and the other end being rotatably connected to the rotating part; the end of the rotating part away from the fixed part extends out of the mounting cavity, and the circumference of the part of the rotating part located in the mounting cavity is provided with an external thread; the side plate is equipped with an adjusting member, the adjusting member having an adjusting screw hole, the internal thread of the adjusting screw hole being threadedly engaged with the external thread.

[0024] By adopting the above technical solution, the rotating part is rotated so that it moves horizontally under the action of the adjusting screw hole, thereby driving the first abutting roller to move. When both first abutting rollers in the same group move, the vertical offset of the wall can be adjusted, so that the wall remains in a vertical state.

[0025] Optionally, the first spring abuts against the inner wall of the fixed cylinder.

[0026] By adopting the above technical solution, the frictional energy dissipation during the vertical movement of the wall is increased, thereby further improving the shock absorption effect.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By setting multiple first abutment rollers to clamp the wall and setting multiple second abutment rollers to support the wall, and both the first and second abutment rollers are wrapped with rubber sheets, the wall is in a suspended state, reducing the risk of the wall cracking during an earthquake;

[0029] 2. By setting gears and racks, the friction between the wall and the second contact roller during the up-and-down movement of the wall consumes energy, further improving the shock absorption effect;

[0030] 3. By having the two first abutting rollers in the same group share a single rubber sheet, the contact area between the rubber sheet and the wall is increased, thereby improving the clamping effect and shock absorption effect of the first abutting roller on the wall.

[0040] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0041] This application discloses a prefabricated partition wall.

[0042] Example 1

[0043] Reference Figure 1The prefabricated partition wall 2 includes a fixed frame 1 and a wall 2, with the wall 2 installed within the fixed frame 1. The wall 2 is made of dimmable glass. The fixed frame 1 includes a pair of side rails 3 and a pair of frame strip assemblies 4. The pair of side rails 3 are respectively attached to the vertical walls on the left and right sides of the wall 2, and the pair of frame strip assemblies 4 are located on the upper and lower sides of the wall 2. The pair of frame strip assemblies 4 are used to fix to the upper and lower floor slabs of the building to achieve the installation of the wall 2.

[0044] Reference Figure 2 The frame strip assembly 4 includes a channel strip 41, a first abutting roller 42, and a second abutting roller 43. The channel strip 41 includes a base plate 411 and side plates 412 disposed on both sides of the base plate 411. The connection methods between the side plates 412 and the base plate 411 include, but are not limited to, welding and integral molding. The base plate 411 is used for fixed connection with the floor slab of the building; in this embodiment, it is fixed by anchor bolts.

[0045] The side plate 412 and the bottom plate 411 together form a mounting cavity 413. The wall 2 has a main body 21 and mounting portions 22 located on the upper and lower sides of the main body 21. The mounting portions 22 are located in the mounting cavity 413, and the main body 21 extends into the mounting cavity 413. The surface of the mounting portion 22 facing away from the main body 21 is defined as the abutment surface 23. The abutment surface 23 is arc-shaped, and there is a clearance between the abutment surface 23 and the bottom plate 411.

[0046] A force equalizing strip plate 24 is fixedly connected to the contact surface 23. A second spring 25 is fixedly connected to the force equalizing strip plate 24. The end of the second spring 25 away from the force equalizing strip plate 24 is fixedly connected to the base plate 411, thereby using the second spring 25 to support the wall 2 and to buffer it during the up and down movement of the wall 2.

[0047] Two sets of first abutting rollers 42 are provided. The two sets of first abutting rollers 42 are respectively connected to the side plates 412 on both sides of the base plate 411 via support rods 421. The two sets of first abutting rollers 42 abut against two mutually opposite surfaces of the main body 21. Each set of first abutting rollers 42 contains multiple first abutting rollers 42. The multiple first abutting rollers 42 are arranged at intervals along the height direction of the wall 2, thereby using the first abutting rollers 42 to form a stable clamping of the main body 21 of the wall 2.

[0048] Reference Figure 2 and Figure 3Two sets of second abutment rollers 43 are provided, located on both sides of the second spring 25. Each set of second abutment rollers 43 contains multiple second abutment rollers 43, which are arranged at intervals along the circumference of the abutment surface 23. The second abutment rollers 43 are used to abut against the abutment surfaces 23 on both sides of the second spring 25, thereby providing stable support for the wall 2. Rubber sheets 44 are wound around the periphery of both the second abutment rollers 43 and the first abutment rollers 42, and the surface of the rubber sheets 44 is used to abut against the surface of the wall 2.

[0049] Reference Figure 3 The second abutment roller 43 is connected to the channel strip 41 via an elastic component 45, which includes a fixed cylinder 451, a movable rod 452, and a first spring 453. The end of the fixed cylinder 451 is fixedly connected to the inner wall of the channel strip 41. One end of the movable rod 452 is connected to the second abutment roller 43, and the other end passes through the fixed cylinder 451. The first spring 453 is located inside the fixed cylinder 451, with one end connected to the end of the fixed cylinder 451 away from the second abutment roller 43, and the other end connected to the end of the movable rod 452 away from the second abutment roller 43. This design provides space for the vertical movement of the wall 2 and, by adding the first spring 453, increases cushioning while reducing rigid damage to the wall 2.

[0050] To increase energy consumption and improve shock absorption, the first spring 453 abuts against the inner wall of the fixed cylinder 451, and the movable rod 452 abuts against the inner wall of the fixed cylinder 451.

[0051] Among them, reference Figure 3 and Figure 4 The specific connection method between the movable rod 452 and the second abutting roller 43 is as follows: multiple movable rods 452 are provided, and these multiple movable rods 452 are arranged at intervals along the length direction of the grooved strip 41. A limiting ring 4521 is fixedly connected to the end of the movable rod 452 away from the first spring 453. Multiple limiting grooves 431 are formed on the circumference of the second abutting roller 43, and these grooves are arranged at intervals along the length direction of the second abutting roller 43. Each limiting groove 431 corresponds to one limiting ring 4521. The portion of the second abutting roller 43 located in the limiting groove 431 passes through the limiting ring 4521, and the limiting ring 4521 is located within the limiting groove 431. It can be understood that a similar structure can also be used to connect the support rod 421 and the first abutting roller 42.

[0052] With the above structure, two sets of first abutment rollers 42, each wrapped with a rubber sheet 44, clamp the main body 21 of the wall 2, while two sets of second abutment rollers 43, also wrapped with rubber sheets 44, and a second spring 25 provide support for the wall 2. This keeps the wall 2 suspended, reducing the risk of the grooved strip 41 transmitting vibration force to the wall 2 and causing it to crack. Simultaneously, when vibration occurs, the wall 2 moves up and down. During this movement, relative friction occurs between the wall 2 and the first abutment rollers 42, converting the kinetic energy of the wall 2 into the elastic potential energy and heat energy of the rubber sheet 44. This provides shock absorption for the wall 2, further reducing the risk of it cracking.

[0053] Furthermore, refer to Figure 5 and Figure 6 The base plate 411 has a first extension 414 at both ends, and the side plate 412 has a second extension 415 at both ends. The side baffle 3 has a bent portion 31 at both ends. The bent portion 31 is welded and fixed to the first extension 414 and the bent portion 31 is welded and fixed to the second extension 415, so that the side baffle 3 and the channel strip 41 are combined to form a fixing frame 1 for mounting the wall 2.

[0054] The bending portion 31, the first extension portion 414, and the second extension portion 415 together form a control cavity 416. A gear 46 is coaxially fixed to the end of the second abutting roller 43, and the gear 46 is located in the control cavity 416. A rack 47 is provided in the control cavity 416, which is used to drive all the second abutting rollers 43 in the same group to rotate in the same direction. A first sliding member 471 is provided on one side of the rack 47, and a second sliding member 472 is provided on the other side. A first guide member 48 is fixedly connected to the end of the abutting surface 23. The first guide member 48 has a first guide groove 481, which is used for the sliding of the first sliding member 471. The distance between the first guide groove 481 and the second extension portion 415 gradually increases from the end closer to the first extension portion 414 to the other end. A second guide member 49 is provided in the control cavity 416. The second guide member 49 is fixedly connected to the bending part 31 and the first extension part 414. The rack 47 is located between the second guide member 49 and the first guide member 48. The second guide member 49 has a second guide groove 491, which is used for sliding connection of the second guide member 49. The second guide groove 491 is coaxially arranged with the abutment surface 23.

[0055] With this design, when the wall 2 moves downward, it drives the first guide member 48 to move downward. Under the guidance of the first guide groove 481, the first sliding member 471 moves away from the second extension 415. The first sliding member 471 drives the rack 47 to move. The rack 47 moves along the direction of the second guide groove 491 under the constraint of the second sliding member 472 and the second guide groove 491. During the movement of the rack 47, it drives the gear 46 to rotate. At the contact position between the second abutting roller 43 and the wall 2, the movement direction of the contact point between the second abutting roller 43 and the wall 2 is opposite to the movement direction of the wall 2. During the upward movement of the wall 2, the above actions are performed in reverse, so that during the upward and downward movement of the wall 2, relative friction is formed between the second abutting roller 43 and the abutting surface 23, thereby consuming energy through friction between the wall 2 and the second abutting roller 43, further improving the shock absorption effect on the wall 2.

[0056] The implementation principle of Example 1 is as follows: First, multiple first abutting rollers 42 are used to clamp the wall 2, and multiple second abutting rollers 43 and a second spring 25 are used to support the wall 2. Rubber sheets 44 are wrapped around the periphery of the first abutting rollers 42 and the second abutting rollers 43, thereby forming multi-point elastic abutment on the wall 2, so that the wall 2 is in a suspended state, so as to reduce the vibration force of the groove strip 41 is directly transmitted to the wall 2 and cause the wall 2 to crack. At the same time, the impact of vibration on the service life of the dimming glass partition wall is reduced.

[0057] Secondly, during the up-and-down movement of the wall 2, energy is dissipated through the friction between the rubber sheet 44 on the first contact side and the wall 2, thus playing a shock-absorbing role for the wall 2.

[0058] Finally, during the up-and-down movement of the wall 2, the wall 2 drives the first guide member 48 to move, which in turn drives the rack 47 to move along the second guide groove 491. At the same time, the rack 47 drives the gear 46 to rotate, so that the contact point between the first abutting roller 42 and the wall 2 rotates in the opposite direction to the direction of movement of the wall 2, thereby further damping the wall 2 and reducing the risk of the wall 2 cracking.

[0059] Example 2

[0060] Reference Figure 7 Based on Embodiment 1, the difference between this embodiment and Embodiment 1 is that a group of first abutting rollers 42 includes two first abutting rollers 42, and the rubber sheet 44 of the two first abutting rollers 42 in the same group is the same piece, and the part of the rubber sheet 44 located between the two first abutting rollers 42 abuts against the surface of the wall 2.

[0061] A connecting rod 417 is fixedly connected to the side plate 412. The connecting rod 417 is horizontally positioned, and a limiting plate 418 is fixedly connected to the end of the connecting rod 417 away from the side plate 412. The limiting plate 418 is located between the two first abutting rollers 42 and abuts against the rubber sheet 44 between the two first abutting rollers 42. With this design, during the up-and-down movement of the wall 2, the rubber sheet 44 between the two first abutting rollers 42 always abuts against the wall 2, thereby increasing the contact area between the wall 2 and the rubber sheet 44, and further improving the clamping effect and shock absorption effect of the first abutting rollers 42 on the wall 2.

[0062] Furthermore, the rubber sheet 44 has multiple protrusions 441 integrally formed on the surface away from the wall 2, and these protrusions 441 are evenly distributed on the surface of the rubber sheet 44. As the wall 2 moves up and down, the first abutting roller 42 rotates, causing the rubber sheet 44 to detach from one of the first abutting rollers 42 and simultaneously wrap around the other. This means the rubber sheet 44 moves relative to the first abutting roller 42. During this process, the multiple protrusions 441 intermittently pass between the first abutting roller 42 and the wall 2, causing the contact force between the rubber sheet 44 and the wall 2 to intermittently increase, further increasing the frictional energy consumption during the up-and-down movement of the wall 2.

[0063] Example 3

[0064] Reference Figure 8 Based on Embodiment 1, the difference between this embodiment and Embodiment 1 is that the support rod 421 includes a fixed part 422 and a rotating part 423. One end of the fixed part 422 is connected to the first abutting roller 42, and the other end is rotatably connected to the rotating part 423. The end of the rotating part 423 away from the fixed part 422 extends out of the mounting cavity 413 and is used for hand gripping. The circumference of the part of the rotating part 423 located in the mounting cavity 413 is provided with external threads. The side plate 412 is equipped with an adjusting member 424, which has an adjusting screw hole 425. The internal thread of the adjusting screw hole 425 is threaded with the external thread. With this design, by rotating the rotating part 423, the rotating part 423 moves horizontally under the action of the adjusting screw hole 425, thereby driving the first abutting roller 42 to move. When both first abutting rollers 42 in the same group move, the vertical offset of the wall 2 can be adjusted, thereby keeping the wall 2 in a vertical state.

[0065] The above are all preferred embodiments of this application, 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.
