Description

Technical Field

[0001] This invention relates to the field of building decoration technology, and in particular to a double-bed prefabricated floor raised system. Background Technology

[0002] In the field of building decoration engineering, floor decoration is one of the core links of overall decoration. Its construction technology, functional adaptability and ease of maintenance directly affect the user experience, space utilization and life cycle cost of the building. As the construction industry transforms towards industrialization, greening and intelligence, traditional floor decoration technology has gradually exposed many drawbacks and is difficult to meet the diversified needs of modern buildings for floor systems. Against this background, various new types of raised floor systems have emerged, and the double bed prefabricated raised floor system is a highly representative technological achievement.

[0003] Chinese invention patent CN120231416A discloses a ground-supplied air duct structure, including an upper floor, a lower floor, and multiple overhead support columns. The upper surface of the lower floor has the multiple overhead support columns regularly distributed thereon. The lower surface of the upper floor has multiple first mounting grooves that correspond one-to-one with the multiple overhead support columns. The tops of the multiple overhead support columns are respectively installed in the corresponding first mounting grooves to support and fix the upper floor, thereby forming an overhead space between the lower floor and the upper floor. A first insulation board layer has multiple first mounting holes that correspond one-to-one with the multiple overhead support columns, so that when the first insulation board layer is stacked under the fiber cement board layer, the multiple first mounting holes surround the multiple first mounting grooves.

[0004] The existing elevated support columns are fixedly connected to the upper and lower floor structures, making it impossible to independently fine-tune the support height of a single elevated support column. When there are unevenness or construction errors in the ground base, it can easily lead to local shaking and uneven stress on the upper floor, seriously affecting the stability of the ground system. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a double-bed prefabricated raised floor system.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a double-bed prefabricated floor system, comprising multiple floorboards and multiple sets of support mechanisms, wherein the multiple floorboards are disposed on corresponding support mechanisms, and the multiple sets of support mechanisms are distributed in a rectangular array, each support mechanism comprising a support component, the support component comprising a base with a hollow structure and an open top disposed below the floorboards, a central column threadedly connected to the base, a top column disposed on the central column, a support plate disposed on the top column, and four partitions fixed to the top of the support plate and evenly distributed about the axis of the support plate, wherein the four corners of any floorboard overlap the top of the corresponding support plate and are located between two corresponding partitions.

[0007] By adopting the above technical solution, four sets of support mechanisms are first placed on the ground. Then, the four corners of the floor are respectively attached to the top of the corresponding support plates and positioned between the corresponding two partitions. If one corner of the floor wobbles, the corresponding central column can be rotated to make the corresponding support plate fit against the wobble corner of the floor until the wobble is resolved. This improves the overall performance and stability after installation, while reducing the requirements for the flatness of the installation ground. In addition, the height of multiple sets of support mechanisms can be adjusted simultaneously, thereby adjusting the distance between the floor and the ground, which can be operated as needed and expands the scope of application.

[0008] Furthermore, the intermediate column is a hollow structure with an open top. The top column is threadedly connected to the inner wall of the intermediate column. The support mechanism also includes a locking assembly. The locking assembly includes an internally threaded tube fixed to the top of the top column. The internally threaded tube passes through the support plate and is inserted into it. The locking assembly also includes a threaded column threadedly connected to the internally threaded tube, a limiting block fixed to the upper end of the threaded column, and a clamping ring fixed to the bottom of the limiting block. The lower end of the clamping ring is clamped to the upper end of the support plate. Notches are opened at the top of each of the four corners of the floor. The side of the limiting block closest to the floor is inserted into the notch and clamped to the notch.

[0009] By adopting the above technical solution, the rotating limiting block drives the clamping ring and the threaded column to rotate until the threaded column separates from the internal threaded tube. At this point, the restriction on one corner of the floor can be released. The setting of the limiting block and the notch improves the stability of the floor after installation. In addition, the support plate can be pulled upwards until it separates from the internal threaded tube, allowing the support plate with other shaped partitions to be connected to the internal threaded tube, thus adapting to the installation of various floor shapes, such as floors with rounded corners. Furthermore, the number of intermediate columns can be increased to change the overall height of the support mechanism, thereby changing the distance between the floor and the ground.

[0010] Furthermore, the bottom of the base is provided with multiple first through holes.

[0011] By employing the above technical solution, the screw is passed through the first through hole and connected to the pre-drilled threaded groove in the ground, thus achieving the installation and fixation of the entire support mechanism. Alternatively, special adhesive can be directly injected into the first through hole from above until the adhesive covers the entire area of ​​the first through hole. After the adhesive dries, the support mechanism can be fixed to the ground.

[0012] Furthermore, a fixing component is provided on the base, and multiple second through holes are provided through the bottom of the base. The fixing component includes fixing modules, the number of fixing modules being equal to the number of second through holes and their positions corresponding one-to-one. Each fixing module includes multiple elastic blocks fixed to the bottom of the base and arranged around the second through holes, and a retaining column inserted into the second through hole. The distance between the inner sidewall of the elastic block and the axis of the retaining column gradually decreases from top to bottom. The lower end of the retaining column is frustum-shaped, and the outer diameter of the frustum-shaped retaining column gradually decreases from top to bottom. The fixing component also includes a lifting module for driving the retaining column to rise and fall.

[0013] By adopting the above technical solution, firstly, multiple elastic blocks on each fixed module are inserted into the pre-drilled mounting grooves in the ground until the central column is in contact with the ground. Then, the lifting module is operated to drive the clamping column to descend. During the descent of the clamping column, the distance between the inner wall of the elastic block and the axis of the clamping column gradually decreases from top to bottom. The lower end of the clamping column is a frustum shape, and the outer diameter of the frustum shape of the clamping column gradually decreases from top to bottom. The elastic blocks deform and fit tightly towards the inner wall of the mounting groove, thereby completing the fixing of the central column. On the one hand, there is no need to drill holes and then open threads. On the other hand, multiple elastic blocks can be fixed to the corresponding mounting grooves at the same time, which facilitates the overall installation of the support mechanism.

[0014] Furthermore, the top of the base is provided with a connecting groove, and the lifting module includes a connecting plate that is fixed to the top of multiple abutting columns and an annular plate that is sleeved on the connecting groove and threadedly connected to the connecting groove. The connecting plate is sleeved on the connecting groove, and the connecting plate and the annular plate are rotatably connected and coaxially arranged. The surface of the annular plate is provided with multiple grooves.

[0015] By adopting the above technical solution, rotating the annular plate, due to its threaded connection with the connecting groove, causes the connecting plate, which is rotatably connected to the annular plate, and the clamping column fixed to the connecting plate to both descend or rise. This allows the elastic block to be pressed against or released from the inner wall of the mounting groove. Multiple grooves are provided on the surface of the annular plate, reducing the probability of slippage during rotation.

[0016] Furthermore, the fixing assembly also includes a locking module, which includes a mounting shell fixed to the top of the annular plate and coaxially arranged with the annular plate, a ratchet fixed to the top of the base and having an annular structure, a connecting shell disposed within the mounting shell, and a pawl rotatably mounted on the connecting shell and engaging with the ratchet groove corresponding to the ratchet. The fixing assembly also includes a limiting module for driving the pawl to reset during the process of the pawl moving from one ratchet groove of the ratchet to the other ratchet groove of the ratchet and keeping the pawl stationary when the pawl is subjected to reverse force.

[0017] By adopting the above technical solution, during the process of rotating the annular plate and lowering the connecting plate, the mounting shell connected to the annular plate, the connecting shell connected to the mounting shell, and the pawl connected to the connecting shell all rotate. During the process of the pawl moving from one ratchet groove of the ratchet wheel to the other ratchet groove of the ratchet wheel, the pawl first rotates away from the ratchet groove of the ratchet wheel it is mating with, the pawl is subjected to force and rotates, and finally the pawl moves to the position of the other ratchet groove of the ratchet wheel. The limiting module drives the pawl to move in the opposite direction and reset until the pawl is inserted and mated with the corresponding ratchet groove at this time. Since the limiting module keeps the pawl stationary when the pawl is subjected to reverse force, the annular plate cannot rotate in the opposite direction when the elastic block is pressed against the inner wall of the mounting groove, thereby improving the stability when the elastic block is pressed against the mounting groove.

[0018] Furthermore, the limiting module includes a connecting shaft that passes through the top of the connecting shell and is rotatably connected to the connecting shell, a torsion spring fixed to the connecting shaft and the bottom wall of the connecting shell, and a limiting post fixed to the top of the connecting shell and abutting against one side of the pawl, wherein the pawl is fixed to the connecting shaft.

[0019] By adopting the above technical solution, the pawl rotates away from the ratchet groove of the ratchet wheel it is mating with. The pawl is subjected to force and rotates, which in turn drives the connecting shaft fixed to the pawl to rotate synchronously. The torsion spring is subjected to force and gradually contracts. When the pawl moves to the other ratchet groove position of the ratchet wheel, the torsion spring gradually expands and resets, which in turn drives the connecting shaft connected to the torsion spring and the pawl fixed to the connecting shaft to rotate in the same direction until the pawl is inserted into the corresponding ratchet groove, so that the ring plate can be locked in the opposite direction.

[0020] Furthermore, the fixing assembly also includes a displacement assembly, which includes a slide rod fixed inside the mounting housing and a threaded rod rotatably mounted on the side wall of the connecting housing away from the ratchet. The side wall of the mounting housing is provided with a threaded through hole that is threadedly connected to the threaded rod, and the slide rod passes through the connecting housing and slides in cooperation with the connecting housing.

[0021] By adopting the above technical solution, the threaded rod is rotated, and due to the limiting effect of the slide bar, the threaded rod is threadedly connected to the threaded through hole. The threaded rod is rotatably connected to the connecting shell, so that the connecting shell and the pawl connected to the connecting shell can both move away from the ratchet until the connecting shell contacts the inner side wall of the mounting shell. At this time, the annular plate can be rotated in the opposite direction to realize the operation of disassembling the support mechanism from the ground, so as to facilitate the subsequent replacement of the support mechanism.

[0022] Furthermore, the mounting shell is provided with auxiliary components, including a rectangular insert fixed to the top of the mounting shell and a handle disposed on the insert. The top of the handle is provided with a through hole for insertion into the insert. The number of inserts is equal to the number of through holes and their positions correspond one-to-one. The side wall of the handle is provided with an auxiliary through hole. The distance between the inner top wall and the inner bottom wall of the auxiliary through hole is between 1.5cm and 2.5cm. Anti-slip grooves are provided on both sides of the side wall of the handle.

[0023] By adopting the above technical solution, pulling the handle upwards until the insertion hole separates from the plug block, then connecting one of the insertion holes to one of the plug blocks, and finally rotating the handle, will cause the plug block connected to the handle, the mounting shell connected to the plug block, and the annular plate connected to the mounting shell to rotate. This provides assistance during the installation or disassembly of the support mechanism to the ground. The auxiliary through hole facilitates pulling the handle upwards. The anti-slip groove reduces the probability of slipping when operating the handle.

[0024] Furthermore, the intermediate pillars are provided with multiple threads that are threaded together to increase the overall height. Each threaded segment of the intermediate pillar is threaded with a positioning ring. The surface of the positioning ring is provided with multiple rectangular grooves to reduce slippage when the positioning ring is rotated.

[0025] By adopting the above technical solution, the change in the number of intermediate columns increases the overall height of the support mechanism, and the setting of the positioning ring improves the stability of the connection between intermediate columns and between the intermediate columns and the base.

[0026] In summary, the present invention has the following beneficial effects: By improving upon existing technologies, this application enhances the overall usability and stability after installation, while reducing the requirements for the flatness of the installation surface. Furthermore, the height of multiple support mechanisms can be adjusted simultaneously, thereby adjusting the distance between the floor and the ground, allowing for operation as needed and expanding its applicability.

[0042] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0043] Example 1: As Figure 1-5As shown in the illustration, this application discloses a double-bed prefabricated raised floor system, including a floor 1 and a support mechanism 2. Multiple floor 1s are provided. Each floor 1 is respectively mounted on a corresponding support mechanism 2, which is arranged in a rectangular array. Notches 3 are provided at the top of each of the four corners of the floor 1. Each support mechanism 2 includes a support component 21 and a locking component 22. The support component 21 includes a base 211, a middle column 212, a top column 213, a support plate 214, and a partition plate 215. The base 211 is located below the floor 1 and has a hollow structure with an open top. The middle column 212 is threadedly connected to the base 211. The top column 213 is mounted on the middle column 212, which is also a hollow structure with an open top. The top column 213 is threadedly connected to the inner wall of the middle column 212, and the support plate 214 is mounted on the top column 213. Four partitions 215 are provided, all fixed to the top of the support plate 214 and evenly distributed about the axis of the support plate 214. The four corners of any floor panel 1 overlap the top of the corresponding support plate 214 and are located between two corresponding partitions 215. First, the four sets of support mechanisms 2 are placed on the ground. Then, the four corners of the floor panel 1 are overlapped with the top of the corresponding support plate 214 and located between two corresponding partitions 215. If one corner of the floor panel 1 wobbles, the corresponding central column 212 can be rotated to make the corresponding support plate 214 fit against the wobbling corner of the floor panel 1 until the wobbling corner of the floor panel 1 is relieved. This improves the overall usability and stability after installation, while reducing the requirement for a flat installation surface. Furthermore, the height of multiple sets of support mechanisms 2 can be adjusted simultaneously, thus adjusting the distance between the floor panel 1 and the ground, allowing for operation as needed and expanding the applicability.

[0044] The locking assembly 22 includes an internally threaded tube 221, a threaded post 222, a limiting block 223, and a retaining ring 224. The internally threaded tube 221 is fixed to the top of the top post 213. The internally threaded tube 221 passes through the support plate 214 and is inserted into it. The threaded post 222 is threaded into the internally threaded tube 221. The limiting block 223 is fixed to the upper end of the threaded post 222, and the retaining ring 224 is fixed to the bottom of the limiting block 223. The side of the limiting block 223 closest to the floor 1 is inserted into the notch 3 and abuts against the notch 3. The lower end of the retaining ring 224 abuts against the upper end of the support plate 214. Rotating the limiting block 223 causes the retaining ring 224 and the threaded post 222 to rotate until the threaded post 222 separates from the internally threaded tube 221. At this point, the restriction on one corner of the floor 1 is released. The setting of the limiting block 223 and the notch 3 improves the stability of the floor 1 after installation. Furthermore, the support plate 214 can be pulled upwards until it separates from the internally threaded tube 221, allowing the support plate 214 with other shaped partitions 215 to be connected to the internally threaded tube 221. This allows for installation on various floor shapes 1, such as floor 1 with rounded corners. Additionally, increasing the number of intermediate columns 212 can change the overall height of the support mechanism 2, thereby altering the distance between the floor 1 and the ground.

[0045] The bottom of the base 211 has multiple through holes 4. By passing screws through the through holes 4 and connecting them to pre-drilled threaded grooves in the ground, the entire support mechanism 2 can be installed and fixed. Alternatively, special adhesive can be injected directly into the through holes 4 until it covers the entire area. After the adhesive dries, the support mechanism 2 can be fixed to the ground.

[0046] Example 2: Figure 6-12As shown in the illustration, this application discloses a double-bed prefabricated raised floor system, including a floor 1, a support mechanism 2, a fixing component 6, and an auxiliary component 9. Multiple floor 1s are provided. Each floor 1 is respectively mounted on a corresponding support mechanism 2, which is arranged in a rectangular array. Notches 3 are provided at the top of each of the four corners of the floor 1. Each support mechanism 2 includes a support component 21 and a locking component 22. The support component 21 includes a base 211, a middle column 212, a top column 213, a support plate 214, and a partition plate 215. The base 211 is located below the floor 1 and has a hollow structure with an open top. Multiple second through holes 5 are provided through the bottom of the base 211. A connecting groove 7 is provided at the top of the base 211, and the middle column 212 is threaded into the base 211. The top column 213 is mounted on the middle column 212, which is also a hollow structure with an open top. The top column 213 is threaded to the inner wall of the intermediate column 212, and the support plate 214 is mounted on the top column 213. Four partition plates 215 are provided, all fixed to the top of the support plate 214 and evenly distributed about the axis of the support plate 214. The four corners of any one partition plate 215 overlap the top of the corresponding support plate 214 and are located between two corresponding partition plates 215. The locking assembly 22 includes an internally threaded tube 221, a threaded column 222, a limiting block 223, and a retaining ring 224. The internally threaded tube 221 is fixed to the top of the top column 213. The internally threaded tube 221 passes through the support plate 214 and is inserted into it. The threaded column 222 is threaded into the internally threaded tube 221. The limiting block 223 is fixed to the upper end of the threaded column 222, and the retaining ring 224 is fixed to the bottom of the limiting block 223. The limiting block 223 is inserted into the notch 3 on the side near the floor 1 and is pressed against the notch 3. The lower end of the pressing ring 224 is pressed against the upper end of the support plate 214.

[0047] A fixing component 6 is mounted on the base 211. The fixing component 6 includes a fixing module 61, a lifting module 62, a locking module 63, a limiting module 64, and a displacement component 65. The number of fixing modules 61 is equal to the number of second through holes 5, and their positions correspond one-to-one. Each fixing module 61 includes an elastic block 611 and a retaining post 612. Multiple elastic blocks 611 are provided, all fixed to the bottom of the base 211 and arranged around the second through holes 5. The distance between the inner wall of the elastic block 611 and the axis of the retaining post 612 gradually decreases from top to bottom. The retaining post 612 is inserted into the second through hole 5. The lower end of the retaining post 612 is frustum-shaped, and the outer diameter of the frustum-shaped retaining post 612 gradually decreases from top to bottom. First, multiple elastic blocks 611 on each fixed module 61 are inserted into the pre-drilled mounting slots in the ground until the central column 212 is in contact with the ground. Then, the lifting module 62 is operated to drive the clamping column 612 to descend. During the descent of the clamping column 612, the distance between the inner wall of the elastic block 611 and the axis of the clamping column 612 gradually decreases from top to bottom. The lower end of the clamping column 612 is frustum-shaped, and the outer diameter of the frustum-shaped clamping column 612 gradually decreases from top to bottom. The elastic blocks 611 deform and fit tightly towards the inner wall of the mounting slot, thereby completing the fixing of the central column 212. On the one hand, there is no need to drill holes and then open threads. On the other hand, multiple elastic blocks 611 can be fixed to the corresponding mounting slots at the same time, which facilitates the overall installation of the support mechanism 2.

[0048] The lifting module 62 is used to drive the lifting and lowering of the clamping columns 612. The lifting module 62 includes a connecting plate 621 and an annular plate 622. The connecting plate 621 is fixed to the top of multiple clamping columns 612 and is sleeved on the connecting groove 7. The connecting plate 621 and the annular plate 622 are rotatably connected and coaxially arranged. The annular plate 622 is sleeved on the connecting groove 7 and threadedly connected to the connecting groove 7. The surface of the annular plate 622 has multiple grooves. Rotating the annular plate 622, since the annular plate 622 is threadedly connected to the connecting groove 7, can drive the connecting plate 621, which is rotatably connected to the annular plate 622, and the clamping columns 612 fixed to the connecting plate 621 to both descend or rise, thereby realizing the operation of the elastic block 611 to be pressed against or released from the inner wall of the mounting groove. The multiple grooves on the surface of the annular plate 622 reduce the probability of slippage when rotating the annular plate 622.

[0049] The locking module 63 includes a mounting housing 631, a ratchet 632, a connecting housing 633, and a pawl 634. The mounting housing 631 is fixed to the top of the annular plate 622 and is coaxially arranged with the annular plate 622. The ratchet 632 is fixed to the top of the base 211 and has an annular structure. The connecting housing 633 is disposed inside the mounting housing 631, and the pawl 634 is rotatably mounted on the connecting housing 633 and engages with the corresponding ratchet groove of the ratchet 632. During the rotation of the annular plate 622 and the descent of the connecting plate 621, the mounting shell 631 connected to the annular plate 622, the connecting shell 633 connected to the mounting shell 631, and the pawl 634 connected to the connecting shell 633 all rotate. As the pawl 634 moves from one ratchet groove of the ratchet wheel 632 to the other ratchet groove, the pawl 634 first rotates away from the ratchet groove of the ratchet wheel 632 it is mating with. The pawl 634 is then subjected to force and rotates. Finally, the pawl 634 moves to the position of the other ratchet groove of the ratchet wheel 632. The limiting module 64 drives the pawl 634 to move in the opposite direction and reset until the pawl 634 is once again inserted and mated with the corresponding ratchet groove. Since the limiting module 64 keeps the pawl 634 stationary when it is subjected to reverse force, the annular plate 622 cannot rotate in the opposite direction when the elastic block 611 is pressed against the inner wall of the mounting groove, thereby improving the stability when the elastic block 611 is pressed against the mounting groove.

[0050] The limiting module 64 is used to drive the pawl 634 to reset during its movement from one groove of the ratchet 632 to the other groove of the ratchet 632, and to keep the pawl 634 stationary when it is subjected to a reverse force. The limiting module 64 includes a connecting shaft 641, a torsion spring 642, and a limiting post 643. The connecting shaft 641 is disposed through the top of the connecting housing 633 and is rotatably connected to the connecting housing 633. The pawl 634 is fixed to the connecting shaft 641. The torsion spring 642 is fixed to the connecting shaft 641 and the inner bottom wall of the connecting housing 633. The limiting post 643 is fixed to the top of the connecting housing 633 and abuts against one side of the pawl 634. The pawl 634 rotates away from the ratchet groove of the ratchet 632 it is paired with. The pawl 634 is subjected to force and rotates, which in turn drives the connecting shaft 641 fixed to the pawl 634 to rotate synchronously. The torsion spring 642 is subjected to force and gradually contracts. When the pawl 634 moves to the other ratchet groove position of the ratchet 632, the torsion spring 642 gradually expands and returns to its original position, which in turn drives the connecting shaft 641 connected to the torsion spring 642 and the pawl 634 fixed to the connecting shaft 641 to rotate in the same direction until the pawl 634 is inserted into the corresponding ratchet groove, so that the annular plate 622 can be locked in the opposite direction.

[0051] The displacement assembly 65 includes a slide rod 651 and a threaded rod 652. The slide rod 651 is fixed inside the mounting housing 631. The slide rod 651 passes through the connecting housing 633 and slides in engagement with it. The threaded rod 652 is rotatably mounted on the side wall of the connecting housing 633 away from the ratchet 632. A threaded through hole 8, threadedly connected to the threaded rod 652, is provided through the side wall of the mounting housing 631. By rotating the threaded rod 652, due to the limiting effect of the slide rod 651, the threaded rod 652 is threadedly connected to the threaded through hole 8, and the threaded rod 652 is rotatably connected to the connecting housing 633. This allows the connecting housing 633 and the pawl 634 connected to the connecting housing 633 to move away from the ratchet 632 until the connecting housing 633 contacts the inner side wall of the mounting housing 631. At this point, the annular plate 622 can be rotated in the opposite direction to disassemble the support mechanism 2 from the ground, facilitating subsequent replacement of the support mechanism 2.

[0052] Auxiliary component 9 is mounted on mounting housing 631 and includes insert block 91 and handle 92. Insert block 91 is fixed to the top of mounting housing 631 and has a rectangular structure. Handle 92 is mounted on insert block 91. The top of handle 92 has a through hole 10 for inserting into insert block 91. The number of insert blocks 91 is equal to the number of through holes 10, and their positions correspond one-to-one. Pull handle 92 upward until the through hole 10 separates from insert block 91. Then, insert one through hole 10 into one insert block 91. Finally, rotate handle 92, which will rotate insert block 91 connected to handle 92, mounting housing 631 connected to insert block 91, and annular plate 622 connected to mounting housing 631. This provides assistance during the installation or disassembly of support mechanism 2 to the ground.

[0053] An auxiliary through hole 11 is provided through the side wall of the handle 92. The distance between the inner top wall and the inner bottom wall of the auxiliary through hole 11 is between 1.5cm and 2.5cm. Anti-slip grooves are provided on both sides of the side wall of the handle 92. The auxiliary through hole 11 makes it easier to pull the handle 92 upwards. The anti-slip grooves reduce the probability of slipping when operating the handle 92.

[0054] Example 3: Figure 13As shown in the illustration, this application discloses a double-bed prefabricated raised floor system, including a floor 1 and a support mechanism 2. Multiple floor 1s are provided. Each floor 1 is respectively mounted on a corresponding support mechanism 2, which is arranged in a rectangular array. Notches 3 are provided at the top of each of the four corners of the floor 1. Each support mechanism 2 includes a support component 21 and a locking component 22. The support component 21 includes a base 211, intermediate columns 212, a top column 213, a support plate 214, and a partition plate 215. Multiple intermediate columns 212 are provided and threadedly connected to each other to increase the overall height. Each threaded section of the intermediate column 212 is threadedly connected to a positioning ring 12. Multiple rectangular grooves are provided on the surface of the positioning ring 12 to reduce slippage when rotating the positioning ring 12. The positioning ring 12 improves the stability of the connection between intermediate columns 212 and between the intermediate columns 212 and the base 211.

[0055] Example 4: Figure 14 In this embodiment, a limiting post 14 and an elastic groove 13 are added. Specifically, multiple elastic grooves 13 are provided on the side wall of the base 211. The elastic grooves 13, the base 211, the intermediate post 212, the top post 213, and the support plate 214 are all made of rubber and plastic-modified asphalt. Specifically, APP-modified asphalt is premixed with a small amount of maleic anhydride-grafted polypropylene (MAH-g-PP) / SBS to form a masterbatch, which is then mixed with rubber. The APP molecular chains and the rubber molecular chains form an interpenetrating network (IPN), which optimizes the uniformity of the crosslinking network, reduces stress concentration, and improves the elongation at break and resilience. A limiting post 14 is fixed to the bottom wall of each elastic groove 13, and a gap is provided between the upper end of the limiting post 14 and the inner top wall of the elastic groove 13. The elastic groove 13, as well as the elastic groove 13, base 211, intermediate column 212, top column 213, and support plate 214, are all made of rubber and plastic modified asphalt. This increases the elasticity of the overall structure, thereby improving the overall shock absorption effect. At the same time, it reduces the harshness caused by hard contact with the floor 1, thus improving the comfort of use.
