Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and more specifically, it relates to a support device for building construction. Background Technology
[0002] In the field of modern building construction, support devices, as a key auxiliary equipment, play a vital role in ensuring construction safety and improving work efficiency. However, there are still many shortcomings in the support devices for building construction on the market. These problems not only affect construction efficiency and quality, but may also pose potential threats to construction safety.
[0003] The primary problem is that existing support devices are functionally limited and lack an effective workpiece fixing mechanism. Most support devices are only equipped with basic lifting functions and cannot stably limit or clamp the supported workpiece. This design defect causes the workpiece to easily shake or shift during the support process, which not only affects the construction accuracy but also increases safety hazards.
[0004] Secondly, although some improved support devices have added adjustable pressure blocks above the workpiece to achieve upper limit, their adjustment mechanism still has obvious defects. These devices usually use traditional fasteners such as bolts to fix and adjust the position of the pressure blocks. Although this method can achieve basic height adjustment, the operation process is cumbersome and time-consuming. Every time the height needs to be adjusted, the operator must use special tools to perform repeated tightening or loosening operations. This not only reduces work efficiency but also increases the labor intensity of the operator. In emergency situations where rapid adjustment is required, this time-consuming operation method may cause unnecessary delays, affect the construction progress, or even endanger safety.
[0005] In addition, to address the aforementioned issues, some manufacturers have developed pressure block adjustment mechanisms with quick assembly and disassembly functions. These designs aim to simplify the height adjustment process and improve operational convenience. However, these improved designs often suffer from overly simple structures and insufficient stability. In complex construction environments, these simplified structures are susceptible to external factors that can cause them to loosen or fail. For example, continuous vibration, frequent impacts, or severe weather conditions can all lead to the gradual loosening of the fixing mechanism. More seriously, this instability can cause the pressure block to fall off completely, resulting in the loss of fixation for the supported workpiece or standing plate. This not only affects the construction quality but may also lead to serious safety accidents. Utility Model Content

[0017] (III) Beneficial Effects
[0018] Compared with the prior art, the present invention provides a support device for building construction, which has the following beneficial effects:
[0019] 1. The ingenious design of the clamping device solves the problem that traditional support devices cannot stably limit or clamp workpieces. Through the coordinated work of the moving frame, slider, slide groove and pressure block, precise clamping of workpieces or standing plates is achieved. The moving frame is fixed on the slider, and the slider slides in the slide groove, which allows the entire clamping mechanism to be flexibly adjusted in position. The motor drives the first lead screw to rotate, which drives the sliders on both sides to move synchronously, thereby achieving clamping of the workpiece on both sides. This design not only improves the stability and accuracy of clamping, but also greatly reduces the risk of workpiece shaking or displacement, effectively improving construction safety and precision.
[0020] 2. The innovative design of the adjustment device solves the problem of the cumbersome and time-consuming traditional pressure block adjustment mechanism. Through the precise cooperation of the adjustment hole, fixing sleeve, fixing rod, storage groove, limiting sleeve, limiting block, variable diameter groove, variable diameter block, clamping plate and connecting block, a fast and flexible height adjustment system is formed. The operator can quickly release or lock the fixing rod by simply rotating the limiting sleeve without the use of any tools. The special design of the variable diameter groove and variable diameter block ensures the smoothness and accuracy of the adjustment process. The setting of the tension spring and connecting shaft enables the clamping plate to automatically reset, further simplifying the operation process. This design not only greatly improves the adjustment efficiency, but also reduces the labor intensity of the operator, and is especially suitable for frequent adjustments or rapid response in emergency situations.
[0021] 3. The design of the reinforcement mechanism effectively solves the stability problems that may arise from the simplified structure. Through the ingenious cooperation of the moving block, the fixed block, the arc-shaped hole, and the arc-shaped rod, a reliable locking system is formed. The sliding design of the arc-shaped rod in the arc-shaped hole, combined with the elasticity of the arc-shaped spring, ensures the stability and reliability of the locking mechanism. This design can not only effectively prevent the structure from loosening due to external vibration or impact, but also unlock quickly when needed, taking into account both stability and ease of operation. The setting of the guide rail and guide groove further enhances the connection stability between the fixed sleeve and the fixed rod, preventing accidental unlocking. Attached Figure Description

[0032] Please see Figures 1-6A construction support device includes a support frame 1, on which a clamping device is provided. The clamping device includes a movable frame 2, a slider 3, a sliding groove 4, and a pressure block 5. The movable frame 2 is fixedly connected to the outside of the slider 3, and the slider 3 is slidably disposed in the sliding groove 4, which is located inside the support frame 1. An adjustment device is provided on one side of the movable frame 2, which includes an adjustment hole 6, a fixing sleeve 7, a fixing rod 8, a storage groove 9, a limiting sleeve 10, a limiting block 11, a diameter changing groove 12, a diameter changing block 13, a clamping plate 14, and a connecting block 15. Multiple adjustment holes 6 are provided on the movable frame 2. The fixing sleeve 7 is detachably fitted onto the outside of the fixing rod 8, and the fixing rod 8 is detachably passed through the movable frame 2. The storage groove 9 is located on the outside of the fixing rod 8. The limiting sleeve 10 is rotatably sleeved on the outside of the fixed sleeve 7. The limiting block 11 is movably disposed in the fixed sleeve 7. The variable diameter groove 12 is opened in the limiting sleeve 10. The variable diameter block 13 is connected to the limiting block 11 through the connecting block 15, and the variable diameter block 13 is slidably disposed in the variable diameter groove 12. The clamping plate 14 is movably disposed in the storage groove 9. A reinforcing mechanism is provided on the outside of the fixed rod 8. The reinforcing mechanism includes a moving block 16, a fixed block 17, an arc-shaped hole 18, and an arc-shaped rod 19. The moving block 16 is fixedly connected to one side of the limiting sleeve 10. The fixed block 17 is fixedly installed on the outside of the fixed sleeve 7. The arc-shaped rod 19 is fixedly connected to one side of the moving block 16. The arc-shaped hole 18 is opened in the fixed block 17, and one end of the arc-shaped rod 19 is inserted into the arc-shaped hole 18.
[0033] A tension spring 20 is movably installed in the storage slot 9, and the other end of the tension spring 20 is fixedly connected to the inner wall of the card plate 14.
[0034] The inner wall of the fixed sleeve 7 is fixed with a guide rail 21, and the outer side of the fixed rod 8 is provided with a guide groove 22, which is adapted to the guide rail 21.
[0035] Connecting shafts 23 are fixedly provided on both sides of the card plate 14, and the card plate 14 is rotatably installed in the storage slot 9 through the connecting shafts 23.
[0036] An arc-shaped spring 24 is movably sleeved on the outer side of the arc-shaped rod 19, and the two ends of the arc-shaped spring 24 are connected to the fixed block 17 and the movable block 16, respectively.
[0037] In this embodiment, when it is necessary to support the workpiece or the standing plate, firstly, one of these devices is placed on each side, and then the distance between the two devices is adjusted. Then, firstly, the limiting sleeve 10 is rotated, causing the limiting sleeve 10 to drive the moving block 16 to rotate. Then, the moving block 16 drives the arc-shaped rod 19 to rotate, causing the arc-shaped rod 19 to rotate along the arc-shaped hole 18 opened on the inner side of the fixed block 17. The moving block 16 and the fixed block 17 cooperate to compress the arc-shaped spring 24 sleeved on the outer side of the arc-shaped rod 19. The limiting sleeve 10 drives the inner diameter-changing groove 12 to rotate. Due to the special diameter-changing structure design of the diameter-changing groove 12 and the diameter-changing block 13, the diameter-changing block 13 then drives the limiting block 11 to gradually slide outward, so that the limiting block 11 no longer limits one end of the clamping plate 14. When the arc spring 24 is compressed to its limit, the variable diameter block 13 drives the limiting block 11 to move to the outermost side through the connecting block 15, so that one end of the clamping plate 14 completely loses its limiting position. Then, the fixing sleeve 7 is pulled to one side, and the ramp at the top of the inner end of the fixing sleeve 7 gradually stops limiting the outer side of the clamping plate 14. Then, the tension spring 20 will gradually pull the clamping plate 14 back to its original position, so that the clamping plate 14 rotates and resets along the connecting shaft 23 in the receiving groove 9, and one end of the clamping plate 14 gradually retracts into the receiving groove 9. Then, the fixing sleeve 7 is completely removed, and the fixing rod 8 is pulled to the other side to completely remove the fixing rod 8. Then, the pressure block 5 is removed from one side of the moving frame 2, and then the two ends of the workpiece or the standing plate are respectively attached to the support frame 1 and placed inside the moving frame 2. A motor 33 is installed on one side of the support frame 1. This motor 33 drives the first lead screw 32 to rotate within the support frame 1. Since the first lead screw 32 has symmetrically opposite threads at both ends, and the slider 3 is movably connected to the first lead screw 32 via threads, the sliders 3 on both sides will synchronously drive the moving frame 2 to move inward along the slide groove 4, thereby clamping the workpiece or the standing plate on both sides. Then, the motor 33 on one side of the support frame 1 is turned off, and the pressure block 5 is placed back on one side of the moving frame 2, ensuring that the preset hole on the pressure block 5 is concentric with the corresponding adjustment hole 6. This allows the lower side of the pressure block 5 to limit and press the upper side of the clamped workpiece or the standing plate. Then, the fixing rod 8 is passed back through the adjustment hole 6 and the pressure block 5, and the fixing sleeve 7 is moved from the other side. One side of the clamping plate 14 is fitted onto the outside of the fixing rod 8, allowing the fixing rod 8 to gradually slide into the inside of the fixing sleeve 7 along the guide rail 21 and guide groove 22. When one side of the clamping plate 14 gradually contacts the ramp inside the fixing sleeve 7, one end of the clamping plate 14 will gradually press inward. Then, the clamping plate 14 will rotate in the receiving groove 9 with the connecting shaft 23 as the center. Then, the other end of the clamping plate 14 will gradually rotate out of the receiving groove 9 and drive the tension spring 20 to stretch. When the fixing sleeve 7 and the fixing rod 8 are pressed tightly against both sides of the movable frame 2, the fixing sleeve 7 is completely fitted onto the outside of the fixing rod 8. At this time, the limiting sleeve 10 is released, and the arc spring 24 pushes the moving block 16 to rotate and reset. Then, the moving block 16 drives the arc rod 19 to rotate and reset along the arc hole 18. At the same time, the moving block 16 drives the limiting sleeve 10 to rotate and reset.Then, the limiting sleeve 10 drives the variable diameter groove 12 to rotate and reset. The variable diameter block 13 then moves along the variable diameter groove 12, and through the connecting block 15, it drives the limiting block 11 to slide inward, causing the limiting block 11 to re-limit one end of the clamping plate 14, preventing the clamping plate 14 from moving. This achieves a stable connection between the fixed sleeve 7 and the fixed rod 8. The guide rail 21 and guide groove 22 ensure that the fixed sleeve 7 and the fixed rod 8 can only move synchronously and provide a guiding function. The arc spring 24 and other components effectively prevent the limiting sleeve 10 from easily rotating, thus strengthening structural stability and preventing easy unlocking that could lead to loss of fixation. When the supported and clamped workpiece or standing plate is too long, an appropriate number of devices can be added between the two devices to ensure overall support strength.
[0038] Please see Figure 1 and Figure 2 As a further embodiment of the overall equipment: a base 25 is provided below the support frame 1, and a movable plate 26 is movably provided inside the base 25. A central shaft 27 is detachably provided on the movable plate 26. The centers of the two movable plates 26 are rotatably connected through the central shaft 27. Movable grooves 28 are opened on the side walls of the base 25 and the support frame 1. Movable shafts 29 are slidably provided in the movable grooves 28. The bottom end of one movable plate 26 is rotatably connected to the base 25, and the top end is movably connected to the support frame 1 through the movable shaft 29 and the movable groove 28. The bottom end of the other movable plate 26 is movably connected to the movable groove 28 opened on the base 25 through another movable shaft 29, and the top end is rotatably connected to the support frame 1.
[0039] A second lead screw 30 is rotatably mounted on the base 25, and a movable block 31 is fixedly mounted on a movable plate 26. The movable block 31 is rotatably connected to the second lead screw 30 through a thread. A first lead screw 32 is rotatably mounted in the support frame 1. The two ends of the first lead screw 32 are symmetrically provided with opposite threads, and the slider 3 is rotatably connected to the first lead screw 32 through a thread.
[0040] Both the support frame 1 and the base 25 have a detachable motor 33 on one side. The output end of the motor 33 on the support frame 1 is connected to one end of the first lead screw 32, and the output end of the motor 33 on the base 25 is connected to the second lead screw 30.
[0041] More specifically, when the support height needs to be adjusted, all motors 33 on one side of the base 25 are turned on simultaneously. The motors 33 drive the second lead screw 30 connected to the output end to rotate. Since the movable block 31 is movably connected to the second lead screw 30 through a thread, the movable block 31 will drive the movable plate 26 to move. The movable plate 26 will then drive the movable shaft 29 at its bottom end to slide along the movable groove 28 opened on the base 25. The part of the movable plate 26 connected to the support frame 1 will rotate. At the same time, the movable plate 26 will drive the central shaft 27 to move, causing the central shaft 27 to rise. The central shaft 27 will then drive another movable plate 26 to move. The part of the movable plate 26 connected to the base 25 at its bottom end will rotate. The movable shaft 29 at the top end of the movable plate 26 will slide along the movable groove 28 opened on the side wall of the support frame 1, causing the support frame 1 and the components installed above it to rise, thereby raising the workpiece or standing plate held in support. After adjusting to the appropriate height, the motors 33 can be turned off.
[0042] In summary, when using or operating the overall equipment: First, when supporting a workpiece or standing platform, place one unit of the equipment on each side and adjust the distance between them. Then, first rotate the limiting sleeve 10, causing the limiting sleeve 10 to drive the moving block 16 to rotate. The moving block 16 then drives the arc-shaped rod 19 to rotate, causing the arc-shaped rod 19 to rotate along the arc-shaped hole 18 inside the fixed block 17. The moving block 16 and the fixed block 17 cooperate to compress the arc-shaped spring 24 sleeved on the outside of the arc-shaped rod 19. The limiting sleeve 10 also drives the inner diameter-changing groove 12 to rotate. Due to the special diameter-changing structure design of the diameter-changing groove 12 and the diameter-changing block 13, the diameter-changing block 13 then drives the limiting block 11 to gradually slide outwards, causing the limiting block 11 to no longer... One end of the clamping plate 14 is limited. When the arc spring 24 is compressed to its limit, the variable diameter block 13 drives the limiting block 11 to move to the outermost side through the connecting block 15, so that one end of the clamping plate 14 completely loses its limit. Then, the fixing sleeve 7 is pulled to one side, and the ramp at the top of the inner end of the fixing sleeve 7 gradually stops limiting the outer side of the clamping plate 14. Then, the tension spring 20 will gradually pull the clamping plate 14 to reset, so that the clamping plate 14 rotates and resets along the connecting shaft 23 in the receiving groove 9, and one end of the clamping plate 14 gradually retracts into the receiving groove 9. Then, the fixing sleeve 7 is completely removed, and the fixing rod 8 is pulled to the other side to completely remove the fixing rod 8. Then, the pressure block 5 is removed from one side of the moving frame 2, and then the two ends of the workpiece or the standing plate are respectively attached to the support frame 1. Position the workpiece inside the movable frame 2, then turn on the motor 33 on one side of the support frame 1. The motor 33 drives the first lead screw 32 to rotate within the support frame 1. Since the first lead screw 32 has symmetrically arranged opposite threads at both ends, and the slider 3 is connected to the first lead screw 32 via threads, the sliders 3 on both sides will synchronously drive the movable frame 2 to move inward along the slide groove 4, thus clamping the workpiece or the standing plate on both sides of the movable frame 2. Then turn off the motor 33 on one side of the support frame 1, and then reposition the pressure block 5 to one side of the movable frame 2, ensuring that the preset hole on the pressure block 5 is concentric with the corresponding adjustment hole 6. This allows the lower side of the pressure block 5 to limit and press the upper side of the clamped workpiece or standing plate. Finally, the fixing rod 8 is re-passed through this adjustment point. After completing hole 6 and pressure block 5, the fixing sleeve 7 is fitted onto the outside of the fixing rod 8 from the other side, so that the fixing rod 8 gradually slides into the inside of the fixing sleeve 7 along the guide rail 21 and guide groove 22. When one side of the clamping plate 14 gradually contacts the slope set inside the fixing sleeve 7, one end of the clamping plate 14 will gradually press inward. Then the clamping plate 14 will rotate in the storage groove 9 with the connecting shaft 23 as the center. Then the other end of the clamping plate 14 will gradually rotate out of the storage groove 9 and drive the tension spring 20 to stretch. When the fixing sleeve 7 and the fixing rod 8 are pressed tightly against both sides of the moving frame 2, the fixing sleeve 7 is completely fitted onto the outside of the fixing rod 8. At this time, the limiting sleeve 10 is released, the arc spring 24 pushes the moving block 16 to rotate and reset. Then the moving block 16 drives the arc rod 19 to rotate and reset along the arc hole 18.Simultaneously, the moving block 16 drives the limiting sleeve 10 to rotate and reset, then the limiting sleeve 10 drives the variable diameter groove 12 to rotate and reset, and then the variable diameter block 13 moves along the variable diameter groove 12. The variable diameter block 13, through the connecting block 15, drives the limiting block 11 to slide inward, causing the limiting block 11 to re-limit one end of the clamping plate 14, preventing the clamping plate 14 from moving. This achieves a stable connection between the fixed sleeve 7 and the fixed rod 8. The guide rail 21 and guide groove 22 ensure that the fixed sleeve 7 and the fixed rod 8 can only move synchronously and provide a guiding function. The arc spring 24 and other components effectively prevent the limiting sleeve 10 from easily rotating, thereby strengthening structural stability and preventing easy unlocking that could lead to loss of fixation. When the supported and clamped workpiece or standing plate is too long, an appropriate number of devices can be added between the two devices to ensure overall support strength.
[0043] When the support height needs to be adjusted, all motors 33 on one side of the base 25 are turned on simultaneously. The motors 33 drive the second lead screw 30 connected to the output end to rotate. Since the movable block 31 is movably connected to the second lead screw 30 through a thread, the movable block 31 will drive the movable plate 26 to move. The movable plate 26 will then drive the movable shaft 29 at its bottom end to slide along the movable groove 28 opened on the base 25. The part of the movable plate 26 connected to the support frame 1 will rotate. At the same time, the movable plate 26 will drive the central shaft 27 to move, causing the central shaft 27 to rise. The central shaft 27 will then drive another movable plate 26 to move. The part of the movable plate 26 connected to the base 25 at its bottom end will rotate. The movable shaft 29 at the top end of the movable plate 26 will slide along the movable groove 28 opened on the side wall of the support frame 1, causing the support frame 1 and the components installed above it to rise, thereby raising the workpiece or standing plate held in support. After adjusting to the appropriate height, the motors 33 can be turned off.
[0044] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
