Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to an adjustable height temporary support structure for prefabricated buildings. Background Technology

[0002] Prefabricated construction is a construction method in which some or all of the building components are prefabricated in a factory and then transported to the construction site for assembly. Through standardized design, industrialized production, prefabricated construction, and information management, it achieves the goals of energy conservation, environmental protection, and high efficiency in building products. Compared with traditional construction methods, prefabricated construction can shorten the construction period, reduce resource waste, and improve building quality, making it an important direction for the transformation and upgrading of the construction industry.

[0003] Adjustable height temporary support structures for prefabricated buildings are devices used in prefabricated building construction to temporarily support prefabricated components and flexibly adjust the support height. Through mechanical transmission (such as screw lifting, hydraulic telescopic), nested component sliding, or modular splicing, the height of the support components can be adjusted to adapt to different construction scenarios and component installation requirements.

[0004] In existing technologies, some temporary support structures for prefabricated buildings are often connected and fixed by welding, bolting, and other methods. During installation, a lot of time is required for positioning, calibration, and tightening, which seriously affects the construction progress. When dismantling welded structures, cutting equipment is required, which is not only inefficient but also easily causes irreversible damage to the support components, resulting in severe damage to the support components and making them difficult to reuse. Therefore, an adjustable height temporary support structure for prefabricated buildings is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable-height temporary support structure for prefabricated buildings, aiming to improve the problem of severe damage to support components in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable-height temporary support structure for prefabricated buildings includes a base plate and a support plate. Connecting grooves are respectively formed inside the base plate and the support plate. A limit ring is fixedly connected to the inner wall of each connecting groove. Connecting seats are detachably connected to the top of the base plate and the bottom of the support plate. One of the connecting seats has a linkage groove inside. Multiple springs are fixedly connected to the top inner wall of the linkage groove. A linkage ring is fixedly connected to the bottom of each spring. Multiple linkage columns are fixedly connected to the bottom of each linkage ring. One of the connecting seats has multiple connecting grooves inside. Springs are fixedly connected to the top inner wall of each connecting groove. An L-shaped block is fixedly connected to the bottom of each spring. A protrusion is fixedly connected to the bottom inner wall of the L-shaped block. A pressure block is fixedly connected to the right side of the linkage ring. Adjustment components are fixedly connected to the bottom of the support plate and the top of the base plate.

[0008] As a further description of the above technical solution:

[0009] The adjustment assembly includes two fixed seats, a hydraulic cylinder is rotatably connected to the top of the fixed seat, a driven rod is fixedly connected to the drive end of the hydraulic cylinder, a reinforcing rod is rotatably connected to the outside of the driven rod, and a spring is fixedly connected to the left side of one of the reinforcing rods.

[0010] As a further description of the above technical solution:

[0011] The bottom of the support plate is fixedly connected to two fixing seats 2, and the bottom of the fixing seats 2 is rotatably connected to a connecting column. Two fixing holes are respectively opened inside the fixing seats 2 and inside the fixing seats 1.

[0012] As a further description of the above technical solution:

[0013] The external part of the linkage ring is slidably connected to the inside of the linkage groove, and the bottom of the multiple linkage columns respectively contacts the top of the multiple L-shaped blocks;

[0014] As a further description of the above technical solution:

[0015] The L-shaped block is slidably connected to the inside of the connecting groove, and the outside of the protrusion is in contact with the inner wall of the limiting ring;

[0016] As a further description of the above technical solution:

[0017] The top of the spring three is fixedly connected to the top inner wall of the connecting column, and the outside of the reinforcing rod is slidably connected to the inside of the connecting column;

[0018] As a further description of the above technical solution:

[0019] One of the connecting seats has a fixed post fixedly connected to its top, and a connecting post fixedly connected to the inside of the fixed post;

[0020] As a further description of the above technical solution:

[0021] The top of the connecting column is fixedly connected to the bottom of another connecting seat, and the two fixed seats are respectively fixedly connected to the top of the base plate and the bottom of the support plate on opposite sides.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by aligning the L-shaped block on the connecting seat with the limiting ring groove of the base plate or support plate and inserting it, the L-shaped block is driven into the connecting groove. Then, the protrusion is squeezed by the edge of the groove, causing the L-shaped block to slide down and stretch the second spring. Then, the connecting seat is rotated, and the elastic action of the second spring pulls the protrusion back into the inner wall of the limiting ring. The pressing block drives the linkage ring and linkage column to slide down and squeeze the L-shaped block, so that the protrusion is disengaged from the limiting ring. Rotating the connecting seat can make the L-shaped block disengage from the groove, thereby realizing the quick and accurate installation of the connecting seat and the base plate or support plate. It is convenient and labor-saving, facilitates the turnover of temporary support structures, and effectively improves the installation efficiency of temporary support structures for prefabricated buildings.

[0024] 2. In this utility model, by activating two sets of hydraulic cylinders placed in opposite directions, the driven rod is driven to extend and retract. When the support plate is subjected to external force, the spring three can be squeezed by the reinforcing rod. The two sets of reinforcing rods work together to exert force in opposite directions, pushing the support plate to rise and fall smoothly. The connecting column moves synchronously according to the movement of the adjustment component, and provides stable support to the support plate through the connecting seat. This effectively meets the diverse height adjustment needs of prefabricated buildings, greatly improves construction efficiency and flexibility. The elastic buffer design of the reinforcing rod and the spring three can resist external impact forces in real time, significantly enhancing the vibration resistance and load-bearing safety of the temporary support structure.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 The present invention provides an embodiment of an adjustable height temporary support structure for prefabricated buildings, comprising a base plate 1 and a support plate 14. The base plate 1 provides fixation and support for the upper device, and the support plate 14 provides support for workers or tools. Connecting grooves 2 are respectively provided inside the base plate 1 and the support plate 14. The connecting grooves 2 provide fixation and support for the limiting rings 3. The limiting rings 3 are fixedly connected to the inner wall of the connecting grooves 2. The limiting rings 3 are used to lock the L-shaped blocks 11, thereby fixing the upper device. At the same time, three slots are provided to facilitate the passage of the three L-shaped blocks 11.

[0033] The top of the base plate 1 and the bottom of the support plate 14 are detachably connected to the connecting seat 4. The connecting seat 4 provides space for the linkage groove 5. The linkage groove 5 is opened inside one of the connecting seats 4. The linkage groove 5 provides fixation and support for the spring 6. Multiple springs 6 are fixedly connected to the top inner wall of the linkage groove 5. The springs 6 have elasticity and provide elastic support for the linkage ring 7. After the force is exhausted, the linkage ring 7 can be pulled back to its original position by its own elasticity. The bottom of the multiple springs 6 is fixedly connected to the linkage ring 7. The linkage ring 7 provides fixation and support for the linkage column 8. Multiple linkage columns 8 are fixedly connected to the bottom of the linkage ring 7. The linkage column 8 is used to receive the force from the linkage ring 7 and slide down, thereby squeezing the L-shaped block 11 and causing its protrusion 12 to disengage from the inside of the limiting ring 3.

[0034] One of the connecting seats 4 has multiple connecting grooves 9 inside. The connecting grooves 9 provide fixation and support for the second spring 10. The second spring 10 is fixedly connected to the top inner wall of the connecting groove 9. The second spring 10 has an elastic function and provides elastic support for its L-shaped block 11. After the force is released, it can pull the L-shaped block 11 back to its original position through its own elasticity. The bottom of the second spring 10 is fixedly connected to the L-shaped block 11. The L-shaped block 11 provides fixation and support for the protrusion 12. The bottom inner wall of the L-shaped block 11 is fixedly connected to the protrusion 12. When the L-shaped block 11 enters the interior of the connecting groove 2 through the groove of the limiting ring 3, the protrusion 12 is squeezed from the edge of the groove, which then drives the L-shaped block 11 to slide down and stretches the second spring 10. Then, the connecting seat 4 is rotated to a suitable position. The protrusion 12 is pulled into the inner wall of the limiting ring 3 by the elastic reset of the L-shaped block 11 by the second spring 10, thereby completing the connection and fixation.

[0035] A pressure block 13 is fixedly connected to the right side of the linkage ring 7. The operator presses the pressure block 13, which in turn causes the linkage ring 7 and the linkage column 8 to slide down and squeeze the L-shaped block 11. This causes the protrusion 12 to disengage from the inside of the limiting ring 3. Then, the connecting seat 4 is rotated to a suitable position, and the L-shaped block 11 can disengage through the corresponding slot of the limiting ring 3. An adjustment component is fixedly connected to the bottom of the support plate 14 and the top of the base plate 1.

[0036] Reference Figure 1 and Figure 4 The adjustment assembly includes two fixed seats 15, which provide fixation and support for the hydraulic cylinder 16. The top of the fixed seat 15 is rotatably connected to the hydraulic cylinder 16, which is the power source for adjusting the height. The drive end of the hydraulic cylinder 16 is fixedly connected to a driven rod 17, which receives the force from the hydraulic cylinder 16 to extend and retract. A reinforcing rod 18 is rotatably connected to the outside of the driven rod 17, which is used to reinforce the upper support plate 14. A spring 19 is fixedly connected to the left side of one of the reinforcing rods 18. The spring 19 has an elastic function and provides elastic support for its reinforcing rod 18.

[0037] Reference Figures 2 to 4The bottom of the support plate 14 is fixedly connected to two fixing seats 21. The fixing seats 21 provide fixation and support for the connecting column 20. The bottom of the fixing seats 21 is rotatably connected to the connecting column 20. The connecting column 20 provides limiting and guiding functions for the reinforcing rod 18. The interior of the fixing seats 21 and the interior of the fixing seats 15 are respectively provided with two fixing holes 22. After the main body is installed, the adjusting component is installed and fixed by screwing screws into the fixing holes 22. The external of the linkage ring 7 is slidably connected to the interior of the linkage groove 5. The linkage groove 5 serves to limit and guide the linkage ring 7. The bottom of the multiple linkage columns 8 respectively contacts the top of the multiple L-shaped blocks 11. The linkage columns 8 slide down under the force from the linkage ring 7 to squeeze the L-shaped blocks 11.

[0038] The L-shaped block 11 is externally slidably connected to the inside of the connecting groove 9. The connecting groove 9 provides a limiting and guiding function for the L-shaped block 11. The outside of the protrusion 12 contacts the inner wall of the limiting ring 3. The protrusion 12 is used to engage with the inside of the limiting ring 3, thereby completing the fixation of the temporary support device above. The top of the spring 19 is fixedly connected to the top inner wall of the connecting post 20. The connecting post 20 provides a fixing and supporting function for the spring 19. The outside of the reinforcing rod 18 is externally slidably connected to the inside of the connecting post 20. The connecting post 20 provides a limiting and guiding function for the reinforcing rod 18. A fixing column 24 is fixedly connected to the top of one of the connecting seats 4. The fixing column 24 is the main support structure of the device. A connecting column 23 is fixedly connected inside the fixing column 24. The connecting column 23 can move synchronously according to the movement of the adjustment component. The top of the connecting column 23 is fixedly connected to the bottom of another connecting seat 4. The connecting column 23 is fixed to the support plate 14 through the other connecting seat 4. The two fixing seats 15 are fixedly connected to the top of the base plate 1 and the bottom of the support plate 14 on opposite sides, respectively. The support plate 14 provides fixation and support for the fixing seats 15.

[0039] Working principle: When installing the device, align the L-shaped block 11 on the connecting seat 4 with the groove of the limiting ring 3 on the base plate 1 or support plate 14, and insert it into the connecting groove 2. Then, the protrusion 12 is squeezed by the edge of the groove, causing the L-shaped block 11 to slide down and stretch the second spring 10. Then, rotate the connecting seat 4 to the appropriate position. The elastic action of the second spring 10 pulls the protrusion 12 back into the inner wall of the limiting ring 3, achieving quick installation. When disassembling, press the pressure block 13 to drive the linkage ring 7 and linkage column 8 to slide down and squeeze the L-shaped block 11, so that the protrusion 12 is disengaged from the limiting ring 3. Rotate the connecting seat 4 to disengage the L-shaped block 11 from the groove, achieving convenient disassembly.

[0040] When the height of the device needs to be adjusted, two sets of hydraulic cylinders 16 placed in opposite directions are activated, which drives the driven rod 17 to extend and retract. When the support plate 14 is subjected to external force, the reinforcing rod 18 can compress the spring 19. The elasticity of the spring 19 provides buffering, thereby reinforcing the upper support plate 14. The two sets of reinforcing rods 18 work together to apply force in opposite directions, pushing the support plate 14 to rise and fall smoothly. The connecting column 23 moves synchronously according to the movement of the adjustment component, and provides stable support to the support plate 14 through the connecting seat 4, so as to achieve precise adjustment of the height of the temporary support structure and meet the different construction height requirements of prefabricated buildings.
