Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, specifically to a floor slab support device for prefabricated buildings. Background Technology

[0002] In the field of modern architecture, prefabricated buildings take prefabricated modular components as their core. By manufacturing these components in batches in factories and then transporting them to the construction site for assembly, the goal of rapid and efficient construction can be achieved.

[0003] Prefabricated construction not only improves construction efficiency but also reduces construction costs. In prefabricated construction, floor slabs are a crucial component. As the load-bearing structure of the floor, they support the upper structure, ensuring the building's safety and stability. The selection and installation quality of floor slabs directly affect the overall quality and lifespan of the building. Therefore, during the use of floor slabs, it is essential to ensure they are securely and reliably fixed in their designated positions.

[0004] Chinese Patent Publication No. CN114837457B discloses a floor slab support device for prefabricated buildings. It includes a support base plate, a first load-bearing seat, a second load-bearing seat, a steel pipe, a convex plate, and a concave plate. The support base plate has the first and second load-bearing seats, each detachably mounted with a supporting steel pipe. A sleeve is connected to the upper end of the steel pipe, and the convex plate is mounted on the sleeve. By pulling the concave plate away from the convex plate, and then pulling the concave plate forward and downward, the concave plate engages with the recessed portion of the convex plate. The height of the convex plate can be quickly adjusted using the expansion assembly, facilitating rapid installation and disassembly, thus achieving the function of rapid installation and disassembly and expanding the support area.

[0005] When using the above technology, it is necessary to support floor slabs of different heights. Since the bottom area of ​​the device is fixed, as the support device is raised, its center of gravity shifts upward, resulting in poor stability and making it easy to cause safety accidents. Summary of the Invention

[0006] This invention provides a floor slab support device for prefabricated buildings to solve the problem that the center of gravity of the device shifts upward as the support device is raised due to the fixed bottom area, causing instability.

[0007] The technical solution of the present invention: a floor slab support device for prefabricated buildings, including a fixed plate, one end of the top wall of the fixed plate is provided with a height adjustment mechanism for supporting floor slabs of different heights, one end of the height adjustment mechanism is engaged with a center of gravity adjustment mechanism for adjusting the center of gravity of the support device, and a locking mechanism for tilting the floor slab is fixedly connected inside the height adjustment mechanism.

[0008] Preferably, the height adjustment mechanism includes a micro motor, which is fixedly connected to a fixed plate. The output end of the micro motor is sequentially fixedly connected to a drive bevel gear and a threaded rod. The threaded rod is threadedly connected to a threaded plate, and the threaded plate is fixedly connected to a bent rod. The bent rod is rotatably connected to a rotating shaft one. The rotating shaft one is rotatably connected to a long shaft one inside. Both ends of the outer wall of the long shaft one are rotatably connected to connecting frames. The connecting frames are fixedly connected to the same long shaft two inside. Both ends of the long shaft two are respectively provided with support seats and fixedly connected with baffles.

[0009] Preferably, the center of gravity adjustment mechanism includes a driven bevel gear, which is rotatably connected to a fixed plate. The driven bevel gear is fixedly connected to a lead screw, one end of which is rotatably connected to the fixed plate, and the other end of which is threadedly connected to a sliding plate.

[0010] Preferably, the locking mechanism includes a hydraulic rod, which is fixedly connected to a support base. A support plate is fixedly connected to the output end of the hydraulic rod. A second rotating shaft is fixedly connected to both ends of the support plate and the bottom of the support base. An inclined plate is rotatably connected to the second rotating shaft, and the inclined plate is rotatably connected via the rotating shaft.

[0011] Preferably, the fixing plate is fixedly connected to a limiting rod, and the limiting rod is slidably connected to a threaded plate.

[0012] Preferably, the support base has a slot inside, and the second long shaft passes through the corresponding slot and is fixedly connected to a baffle.

[0013] Preferably, the sliding plate has receiving grooves at both ends of its bottom, and universal wheels are rotatably connected inside the receiving grooves.

[0014] Preferably, the driving bevel gear is meshed with the driven bevel gear.

[0015] Preferably, the bottom of the outer wall of the fixing plate is fixedly connected with multiple extension rods at equal intervals.

[0016] Preferably, a sliding rod is fixedly connected to both sides of the fixed plate, and the sliding rod passes through the corresponding sliding plate and is fixedly connected to a limiting piece.

[0017] The working principle of this invention is as follows: The micro-motor drives the threaded rod to rotate. Under the limiting action of the threaded rod and the limiting rod on the threaded disc, the threaded disc moves up and down with the rotation of the threaded rod, thereby driving the internal support seat to move up and down. This allows the support seat to adapt to supporting floor slabs of different heights. When the driving bevel gear rotates, the driven bevel gear rotates synchronously with it under the action of meshing connection, driving the lead screws at both ends to rotate. The lead screws at both ends are symmetrically placed. Under the limiting action of the bottom surface on the sliding plates on both sides, the sliding plates on both sides slide relative to each other as the lead screws rotate. This causes the bottom support area of ​​the support device of this invention to increase synchronously with the increase of the support seat height, thus enabling the invention to achieve this. The downward shift of the center of gravity of the support device results in greater stability when applying support force to the floor slab. In some buildings, the floor slabs are placed at an angle. When the support device of this invention is used to support the inclined floor slab, it can counteract the vertical gravity and the inclined pressure. The support base is used to support the two ends of the floor slab. The hydraulic rod drives the support plate to move upward, and the angle between the two inclined plates widens, forming a shielding structure with the support plate to lock the two ends of the floor slab and prevent the floor slab from sliding. At the same time, the long axis provides the support base with rotation space, so that the support base can be parallel to the bottom surface of the floor slab at various inclination angles, avoiding damage to the outer wall of the floor slab when supporting it.

[0018] This invention is applicable to floor slabs at various angles, greatly improving the applicability of the support device.

[0019] The present invention has the following beneficial effects:

[0020] 1. This invention utilizes the meshing connection to raise the support base via the height adjustment mechanism, thereby driving the lead screws at both ends to rotate. The lead screws at both ends are symmetrically placed. Under the limiting effect of the bottom surface on the sliding plates on both sides, the bottom support area of ​​the support device increases synchronously with the increase in the height of the support base, and the center of gravity of the support device shifts downward, resulting in higher stability of the device when applying support force to the floor slab.

[0021] 2. The hydraulic rod of this invention drives the support plate to move upward, and the inclined plates on both sides form a shielding structure with the support plate to lock the two ends of the floor slab and prevent the floor slab from sliding. This device is suitable for floor slabs with various angles, which greatly improves the applicability of the support device.

[0022] 3. The present invention provides the support base with rotation space through the long axis, so that the support base can be parallel to the bottom surface of the floor slab with various inclination angles, avoiding damage to the outer wall of the floor slab when the support base is supporting, and increasing the adaptability of the support device.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0033] Please see the appendix Figure 1 - Appendix Figure 8 A floor slab support device for prefabricated buildings includes a fixed plate 1. A height adjustment mechanism is provided at one end of the top wall of the fixed plate 1. The height adjustment mechanism is used to adapt to support floor slabs of different heights. A center of gravity adjustment mechanism is engaged with one end of the height adjustment mechanism. The center of gravity adjustment mechanism is used to adjust the center of gravity of the support device. A locking mechanism is fixedly connected inside the height adjustment mechanism. The locking mechanism is used to tilt the support of the floor slab.

[0034] The height adjustment mechanism includes a micro motor 3, which is fixedly connected to one end of the top wall of the fixed plate 1. The output end of the micro motor 3 is sequentially fixedly connected to an active bevel gear 4 and a threaded rod 7. The outer wall of the threaded rod 7 is threadedly connected to a threaded plate 8. The top wall of the threaded plate 8 is fixedly connected to a bent rod 9. One side of the outer wall of the bent rod 9 is rotatably connected to a rotating shaft 10. The inside of the rotating shaft 10 is rotatably connected to a long shaft 11. Both ends of the outer wall of the long shaft 11 are rotatably connected to connecting brackets 12. The inside of the two connecting brackets 12 is fixedly connected to the same long shaft 2 13. Both ends of the long shaft 2 13 are respectively provided with support seats 16 and fixedly connected to baffles 14.

[0035] A limiting rod 2 is fixedly connected to the other end of the top wall of the fixed plate 1, and another threaded piece 8 is slidably connected to the outer wall of the limiting rod 2.

[0036] Specifically, by starting the micro motor 3, the threaded rod 7 can be driven to rotate. Under the limiting action of the threaded rod 7 and the limiting rod 2 on the threaded plate 8, the threaded plate 8 moves up and down with the rotation of the threaded rod 7, thereby driving the internal support seat 16 to move up and down, so that the support seat 16 can adapt to support floor slabs of different heights. At the same time, a concave structure is formed between the support seat 16 and the connecting frame 12 to support floor slabs of different widths, which greatly improves the adaptability of the support device.

[0037] The center of gravity adjustment mechanism includes a driven bevel gear 5, which is rotatably connected to the inside of the fixed plate 1. Lead screws 6 are fixedly connected to the front and rear sides of the outer wall of the driven bevel gear 5. One end of each lead screw 6 is rotatably connected to the inside of the fixed plate 1, and the other end of each lead screw 6 is threadedly connected to a sliding plate 21.

[0038] The driving bevel gear 4 meshes with the driven bevel gear 5.

[0039] Specifically, when the micro motor 3 starts and drives the active bevel gear 4 to rotate, the driven bevel gear 5 rotates synchronously with it under the action of meshing connection, driving the lead screws 6 at both ends to rotate respectively. The lead screws 6 at both ends are placed symmetrically. Under the limiting action of the bottom surface on the sliding plates 21 on both sides, the sliding plates 21 on both sides slide relative to each other as the lead screws 6 rotate, so that the bottom support area of ​​the support device increases synchronously with the increase of the height of the support base 16, so that the center of gravity of the support device shifts down, and the stability of the device is higher when applying support force to the floor slab.

[0040] The locking mechanism includes a hydraulic rod 20, which is fixedly connected inside the support base 16. The output end of the hydraulic rod 20 is fixedly connected to a support plate 19. Both ends of the support plate 19 and both ends of the inner bottom wall of the support base 16 are fixedly connected to a second rotating shaft 17. The interior of multiple second rotating shafts 17 is rotatably connected to inclined plates 18, and the corresponding inclined plates 18 are rotatably connected through a third rotating shaft 26.

[0041] Specifically, some buildings have floor slabs placed at an angle. When the support device is used to support the angled floor slabs, it mainly counteracts the vertical gravity and the pressure from the angled sides of the floor slab's outer wall. The support base 16 supports both ends of the floor slab. The hydraulic rod 20 drives the support plate 19 to move upward, widening the angle between the two inclined plates 18 and forming a shielding structure with the support plate 19. This places one end of the floor slab between the support plate 19 and the support base 16. At this time, the locking mechanism locks both ends of the floor slab to prevent it from sliding. Meanwhile, the long shaft 11 provides the support base 16 with rotation space, allowing it to be parallel to the bottom surface of floor slabs with various angles of inclination. This device is suitable for floor slabs with various angles, greatly improving the applicability of the support device.

[0042] The support base 16 has a slot 15 inside, and two long shafts 13 pass through the corresponding slots 15 and are fixedly connected to baffles 14.

[0043] Specifically, the through connection between the long shaft 13 and the baffle 14 increases the support space of the support base 16.

[0044] Both ends of the bottom of the outer wall of the two sliding plates 21 are provided with receiving grooves 22, and universal wheels 23 are rotatably connected inside the receiving grooves 22.

[0045] Specifically, the caster wheel 23 improves the sliding ability of the sliding plate 21 when the lead screw 6 rotates, making it easier to increase the support area at the bottom of the support device, reducing the friction between the sliding plate 21 and the ground, and improving work efficiency.

[0046] Multiple extension rods 24 are fixedly connected at equal intervals to the bottom of the outer wall of the fixed plate 1.

[0047] Specifically, the extension rod 24 is made of rubber. The contact between the extension rod 24 and the ground not only increases the friction between the fixed plate 1 and the ground, but also makes the fixed plate 1 encounter greater resistance during movement, thereby effectively reducing the possibility of movement of the fixed plate 1 and providing a strong guarantee for the stability of the support device. In practical applications, a support device with strong stability can greatly improve work efficiency and reduce the risks caused by the movement of the device.

[0048] Both sides of the outer wall of the fixed plate 1 are fixedly connected with sliding rods 27, and the other ends of the two sliding rods 27 pass through the corresponding sliding plates 21 and are fixedly connected with limit plates 25.

[0049] Specifically, the slide rod 27 connects the right sides of the two sliding plates 21, making the bottom support structure formed by the support device more stable. The right-side connection increases the contact area between the slide rod 27 and the sliding plate 21, improving the stability of the connection. During equipment operation, even under large external forces, it can maintain good connection performance and avoid equipment failure caused by unstable connection. The limit plate 25 prevents the sliding plate 21 from falling off the outer wall of the lead screw 6 under the rotation of the lead screw 6.
