Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to an adjustable-height temporary support frame for steel beams in building construction. Background Technology

[0002] In modern building construction, especially steel structure construction, the hoisting and fixing of steel beams is a core step. After the steel beams are hoisted into place and before they are permanently connected to columns or other structural components, temporary support frames are needed to provide them with stable support to ensure their positional accuracy and construction safety.

[0003] Existing temporary support frames are mostly fixed structures, typically welded from steel pipes or structural steel. However, in practical applications, these fixed support frames have the following shortcomings: Inconvenient height adjustment: The installation height of steel beams on the construction site varies, and fixed support frames are difficult to adapt to different elevation requirements. It is often necessary to place pads at the bottom or cut columns, which is cumbersome, difficult to guarantee accuracy, and has poor stability.

[0004] Poor adaptability: For steel beams with a certain slope or working conditions that require fine adjustment of elevation, the top support surface of the traditional support frame cannot be adjusted in angle, resulting in insufficient contact between the support surface and the bottom surface of the steel beam, which can easily lead to stress concentration or slippage risk.

[0005] Low disassembly and turnover efficiency: Traditional support frames are bulky and require welding or cutting equipment for disassembly and assembly, which is time-consuming and labor-intensive, and not conducive to rapid turnover between different construction sections.

[0006] Therefore, developing a highly adjustable, adaptable, and easy-to-operate temporary support frame is of great significance for improving construction efficiency and ensuring project quality. Summary of the Invention

This solves the problem of insufficient contact between the traditional fixed support surface and the bottom surface of the inclined steel beam, achieving complete fit between the support surface and the bottom surface of the steel beam, thus balancing the stability and adaptability of the support.

[0017] 3. Automatic Adsorption and Anti-slip: Based on the linkage structure design of suction cup and air extraction component, air is automatically extracted during the contact between the support platform and the steel beam to achieve adsorption connection, ensuring the stability of the support and avoiding the risk of slippage of the steel beam due to vibration or external force, thus improving the safety of operation.

[0018] 4. Double locking ensures safety: After the support is completed, the clamping components in the auxiliary support unit clamp and lock the limit guide plate, so that the lifting column is fixed under load. This eliminates the risk of equipment falling due to hydraulic failure or sudden load, and ensures the continuity and safety of the construction process. Attached Figure Description

[0029] The technical solution of this application will be further described in detail below with reference to specific embodiments.

[0030] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0031] Please see Figure 1 and Figure 2 In one embodiment of the present invention, a height-adjustable temporary support frame for building steel beams includes: a base 1; a lifting unit 2, which is fixedly disposed on the outer side of the top of the base 1; an adjustable support unit 3, which is disposed on the outer side of the top of the lifting unit 2 and connected to the lifting unit 2, for supporting the steel beam in conjunction with the lifting of the lifting unit 2, and for adjusting the support angle and direction; and an auxiliary support unit 4, which is connected to the base 1, for assisting the base 1 in providing auxiliary support and for clamping the adjusted lifting unit 2; wherein, the adjustable support unit 3 includes: an adjusting component 5 and a supporting component 6, the adjusting component 5 being disposed on the outer side of the top of the lifting unit 2 and connected to the supporting component 6, for adjusting the support angle in conjunction with the adjusting component 5, and for adhering to and supporting the outer wall of the steel beam in conjunction with the lifting of the lifting unit 2.

[0032] In this embodiment, during device operation, the auxiliary support unit 4 enables the base 1 to move. As the device moves and is positioned directly beneath the steel beam to be supported, the auxiliary support unit 4, in conjunction with the base 1, provides support for the device. Subsequently, the adjustment component 5 adjusts the support angle and direction of the support component 6, ensuring that the support component 6 stably fits directly beneath the steel beam during support. The lifting unit 2 operates, cooperating with the adjustment component 5 to raise the support component 6. The support component 6 contacts the bottom of the steel beam. Initially, as the support component 6 continues to move upward, it first adheres to the outer wall of the steel beam, ultimately providing full support to the steel beam. After support is completed, the auxiliary support unit 4... The auxiliary support unit 4 can clamp the lifting unit 2 after it has been adjusted, which not only enhances the stability and reliability of the lifting unit 2 after adjustment, but also avoids the problem of sudden drop and improves the safety of the equipment during use. This application sets up an adjustable support unit 3, which works in conjunction with the lifting unit 2 and the auxiliary support unit 4 to facilitate height adjustment. It can be adjusted according to the installation height of the steel beam at the construction site to adapt to different elevation requirements. It is highly adaptable. For steel beams with a certain slope or for working conditions that require fine adjustment of elevation, the angle of the support surface can be adjusted so that the support surface is in full contact with the bottom surface of the steel beam, ensuring the reliability and stability of the support.

[0033] In one embodiment of the present invention, please refer to Figure 2 and Figure 3 The adjustment assembly 5 includes: a rotary table 7, a connecting frame 8, a support plate 9, a first telescopic member 10, and a steering motor 11. The steering motor 11 is fixedly installed on the outer side of the top of the lifting unit 2. The output end of the steering motor 11 is fixedly connected to the rotary table 7. The connecting frame 8 is rotatably installed on the top of the rotary table 7. The support plate 9, which is connected to the support assembly 6, is fixedly installed on the outer side of the connecting frame 8. The first telescopic member 10 is rotatably installed at the bottom of both ends of the support plate 9. The other end of the first telescopic member 10 is rotatably connected to the rotary table 7.

[0034] In this embodiment, the first telescopic member 10 is an electric push rod. The first telescopic members 10 arranged on both sides of the rotating platform 7 cooperate with each other to drive the support plate 9 to drive the connecting frame 8 to rotate around the connection point with the rotating platform 7. At the same time, the steering motor 11 can realize the rotation of the rotating platform 7, thereby completing the adjustment of the angle and direction of the support component 6, so that the support component 6 can fully contact the bottom surface of the steel beam when supporting, effectively ensuring the reliability and stability of the support.

[0035] In one embodiment of the present invention, please refer to Figure 3The supporting assembly 6 includes: a supporting platform 12, suction cups 13, transmission and control conduits 14, baffles 15, an air extraction component 16, a sliding rod 17, a directional block 18, and a connecting rod 19. The supporting platform 12 is located on the outer side of the top end of the support plate 9. Several suction cups 13 are fixedly installed on the shell wall of the top end of the supporting platform 12. Transmission and control conduits 14 are symmetrically arranged on the outer sides of both ends of the supporting platform 12. The transmission and control conduits 14 are fixedly connected to the supporting platform 12 and slidably connected to the support plate 9. Baffles 15 are slidably installed on the inner side of the support plate 9. The baffle 15 is fixedly connected to the transmission and control conduit 14. A spring is fixedly installed between the baffle 15 and the support plate 9. An air extraction component 16 is slidably installed on the inner side of the other end of the transmission and control conduit 14. The air extraction component 16 is slidably connected to the directional block 18 fixedly installed on the inner side of the transmission and control conduit 14. The slide rod 17 is slidably connected to the air extraction component 16. A spring is fixedly installed between the slide rod 17 and the air extraction component 16. A connecting rod 19 is rotatably installed on the other end of the slide rod 17. The other end of the connecting rod 19 is rotatably connected to the support plate 9.

[0036] In this embodiment, the transmission and control conduit 14 passes through the support plate 9 and is slidably connected to the support plate 9. The air extraction component 16 includes a drive piston slidably disposed inside the transmission and control conduit 14 and a drive rod fixedly connected to the drive piston. The drive rod has a directional groove slidably connected to the directional block 18 on its rod wall. The slide rod 17 is slidably connected to the drive rod, and a spring is fixedly disposed between the slide rod 17 and the drive rod. When the lifting unit 2 drives the rotating table 7 to move upward, the suction cup 13 on the adjusted support platform 12 contacts the outer wall of the bottom end of the steel beam. As the support plate 9 continues to move upward, the distance between the support platform 12 and the support plate 9 decreases. The support platform 12 drives the transmission and control conduit 14 to move relative to the support plate 9. With the cooperation of the connecting rod 19, the air extraction component 16 moves inside the transmission and control conduit 14, thereby completing the extraction of air inside the support platform 12. This allows the suction cup 13 to adhere to the outer wall of the bottom end of the steel beam, thereby improving the effectiveness of the equipment in supporting the steel beam.

[0037] In one embodiment of the present invention, please refer to Figure 2 , Figure 4 and Figure 5 The lifting unit 2 includes: a fixed column 20, a lifting column 21, a lifting motor 22, a threaded rod 23, a control column 24, and a limiting guide plate 25. The fixed column 20 is fixedly installed on the outer side of the top of the base 1. The lifting column 21 is slidably installed on the outer side of the fixed column 20. The top of the lifting column 21 is rotatably connected to the rotating table 7. The lifting motor 22 is fixedly installed on the bottom inner side of the fixed column 20. The output end of the lifting motor 22 is fixedly connected to the threaded rod 23. The threaded rod 23 is threadedly connected to the control column 24 fixedly installed on the inner side of the lifting column 21. Several limiting guide plates 25 are arranged around the outer side of the control column 24. The limiting guide plates 25 are slidably connected to the fixed column 20.

[0038] In this embodiment, the steering motor 11 is fixedly installed on the outer side of the top of the lifting column 21. The top shell wall of the lifting column 21 is rotatably connected to the rotary table 7. The lifting motor 22 drives the threaded rod 23 to rotate. The threaded rod 23, in conjunction with the control column 24, is guided by the limiting guide plate 25 to realize the lifting of the lifting column 21, thereby completing the adjustment of the support height of the adjusting support unit 3. By setting the lifting unit 2, the height can be quickly adjusted and can be changed according to the installation height of the steel beams at the construction site to adapt to different elevation requirements, thus having strong adaptability.

[0039] In one embodiment of the present invention, please refer to Figure 5 The auxiliary support unit 4 includes a support component and a clamping component. The support component is disposed inside the base 1 and connected to the base 1. It is used to cooperate with the base 1 to support the device and realize the movement of the device. A clamping component is provided between the support component and the limiting guide plate 25 to cooperate with the extension and retraction of the support component to clamp the limiting guide plate 25.

[0040] In this embodiment, the extension and retraction of the support component not only supports the equipment but also enables its rapid movement. During the support process, it works in conjunction with the base 1 to support the equipment. After the lifting unit 2 completes its adjustment, it drives the clamping component, which clamps the limiting guide plate 25, further securing it and improving the stability and reliability of the lifting column 21 after lifting. When the equipment malfunctions or the steel beam collapses, causing the lifting column 21 to fall, the clamping component, in conjunction with the limiting guide plate 25, slows down the fall of the lifting column 21, achieving a slow descent and effectively improving the safety of the equipment during use.

[0041] In one embodiment of the present invention, please refer to Figure 5 , Figure 7 and Figure 8 The support assembly includes: a second telescopic member 26, a control frame 27, an auxiliary support plate 32, a retraction control tube 33, casters 34, a control piston 35, a drive control rod 36, a retraction component 37, and a control groove 39. The second telescopic member 26 is fixedly installed on the inner bottom of the base 1. The control frame 27, which is connected to the clamping assembly, is fixedly installed on the outer side of the other end of the second telescopic member 26. Several casters 34 are fixedly installed on the outer side of the bottom end of the control frame 27. An auxiliary support plate 32 is provided between adjacent casters 34 and is slidably connected to the base 1. The support plate 32 and the auxiliary support plate 32 are provided with control grooves 39 on their inner sides. Each control groove 39 is provided with a retraction control tube 33 that is fixedly connected to the base 1. A control piston 35 that is slidably connected to the control groove 39 is fixedly provided on the outer side of one end of the retraction control tube 33, and a retraction component 37 is slidably provided on the inner side of the other end. The retraction component 37 is connected to the control frame 27 through a drive control rod 36, which is used to cooperate with the lifting and lowering of the control frame 27 to realize the retraction and extension of the casters 34 and the auxiliary support plate 32, and to complete the driving of the clamping components.

[0042] In this embodiment, the second telescopic member 26 is an electric push rod, and the retracting member 37 includes a retracting piston slidably disposed inside the retracting control tube 33 and a retracting rod fixedly connected to the retracting piston. A limit groove is provided on the rod wall of the retracting rod, and a limit block 38 slidably disposed inside the limit groove and slidably connected to the inner wall of the retracting control tube 33. Initially, the casters 34 are located outside the base 1, supporting the equipment, which facilitates movement. When the equipment is moved to the designated position, the second telescopic member 26 drives the control frame 27 to move upwards. The control frame 27 drives the casters 34 to retract inside the base 1. The control frame 27 then drives the control rod 36 to... The retractable component 37 moves inside the retractable control tube 33, and the air inside the retractable control tube 33 enters the control slot 39. In conjunction with the control piston 35, it drives the auxiliary support plate 32 to extend from the inside of the base 1, and works with the base 1 to support the equipment, thus enhancing the stability of the equipment during support. At this time, the clamping assembly has not yet fully clamped the limit guide plate 25. After the lifting unit 2 and the adjusting support unit 3 have completed the full support of the steel beam, the second telescopic component 26 continues to move upward. The control frame 27 drives the clamping assembly to complete the clamping of the limit guide plate 25, further enhancing the stability of the equipment during support and improving the safety of the equipment during use.

[0043] In one embodiment of the present invention, please refer to Figure 5 and Figure 6 The clamping assembly includes: a control rod 28, a push-pull rod 29, a guide plate 30, and a buffer plate 31. The buffer plate 31 is slidably disposed inside the limiting guide plate 25. The guide plate 30 is fixedly disposed outside the buffer plate 31. The guide plate 30 is fixedly connected to the fixed column 20. The push-pull rod 29 is rotatably disposed on the buffer plate 31. The control rod 28 is slidably disposed outside the push-pull rod 29. A spring is fixedly disposed between the control rod 28 and the push-pull rod 29. The other end of the control rod 28 is rotatably connected to the control frame 27.

[0044] In this embodiment, when the control frame 27 is raised or lowered, the control frame 27, in conjunction with the transmission rod 28 and the push-pull rod 29, drives the buffer plate 31 to move. The guide plate 30 guides the lateral movement of the buffer plate 31, thereby achieving clamping of the limiting guide plate 25. When the buffer plate 31 is not clamped, it does not come into contact with the limiting guide plate 25, ensuring the stability of the lifting column 21 during raising and lowering. By setting the clamping assembly, the stability of the lifting unit 2 after raising and lowering is enhanced, and the safety of the equipment during use is improved.

[0045] In its initial state, the adjustable-height temporary support frame for building steel beams has casters 34 located outside the base 1 for easy movement. After the equipment is moved directly under the steel beam to be supported, the second telescopic component 26 drives the control frame 27 to move upward, and the casters 34 retract to the inside of the base 1. At the same time, the control frame 27 drives the retraction component 37 to move within the retraction control tube 33 via the drive control rod 36, driving the auxiliary support plate 32 to extend from the inside of the base 1, thus cooperating with the base 1 to provide stable support for the equipment.

[0046] Subsequently, the steering motor 11 drives the rotary table 7 to rotate, and the first telescopic component 10, in conjunction with the drive support plate 9, swings to adjust the support angle and direction of the support platform 12, so that the support platform 12 is fully aligned with the bottom surface of the steel beam. The lifting motor 22 drives the threaded rod 23 to rotate, and in conjunction with the control column 24 and the limit guide plate 25, drives the lifting column 21 to rise, thereby raising the entire adjusting support unit 3.

[0047] After the suction cup 13 on the support platform 12 contacts the bottom surface of the steel beam, as the support plate 9 continues to rise, the distance between the support platform 12 and the support plate 9 decreases, the transmission and control conduit 14 moves relative to the support plate 9, and through the connecting rod 19 drives the air extraction component 16 to slide in the transmission and control conduit 14, extracting the air inside the support platform 12, so that the suction cup 13 is adsorbed and connected to the bottom surface of the steel beam, thus completing the stable support of the steel beam.

[0048] After the support is completed, the second telescopic component 26 continues to move upward. The control frame 27 drives the buffer plate 31 to slide along the guide plate 30 through the control rod 28 and the push-pull rod 29, clamping the limit guide plate 25, further enhancing the stability of the lifting unit 2, preventing the lifting column 21 from suddenly falling due to equipment failure or external impact, and improving the safety of use.

[0049] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these should also be considered within the scope of protection of the present invention. These will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
