Description

Technical Field

[0001] This invention relates to the field of space frame jacking construction technology, and in particular to a detachable triangular support bracket device for hydraulic jacking of space frames. Background Technology

[0002] A space frame is a three-dimensional structural system formed by connecting members and nodes through spatial forces. It features high strength, lightweight, and rational spatial force distribution. Its structural forms include double-layer lower chord supported welded spherical space frames, which are widely used in the roof systems of large-span buildings. Hydraulic jacking of space frames is an installation technology that uses hydraulic equipment to lift a prefabricated space frame structure from the ground or floor to the design elevation. The support frame plays a role in bearing, stabilizing, and guiding the space frame during hydraulic jacking, and is the core temporary structure that ensures the safety of the jacking.

[0003] A search revealed that Chinese patent CN118498530A discloses a method for lifting a terminal building's space frame. Although the space frame is lifted by adding standard sections after the hydraulic cylinders are raised, the large number of components in each standard section means that assembling them in the installation area after the hydraulic cylinders have been raised would reduce construction efficiency. Therefore, this method solves the problem of reduced construction efficiency caused by assembling standard sections with many components in the installation area after the hydraulic cylinders have been raised.

[0004] The above-mentioned splicing steps for the jacking support are quite difficult, and the stability after splicing is low. In the existing technology, when splicing between jacking standard support sections, multiple flanges and bolts and nuts are usually used to connect the standard sections. Each flange requires multiple bolts and nuts for connection, which increases the splicing cost. In addition, the use of multiple bolts during splicing increases the complexity and cumbersomeness of connecting standard support sections, resulting in longer working time and lower efficiency. Bolts and nuts are independent items and are easy to lose. If the required bolts and nuts are missing when splicing standard support sections, it will be difficult to complete the splicing between standard support sections. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a detachable triangular support bracket device for hydraulic lifting of space frames.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a detachable triangular support bracket device for hydraulic lifting of a space frame, including a bottom triangular frame, a plurality of support columns are arranged above the bottom triangular frame, a top triangular frame is arranged above the plurality of support columns, and a quick-assembly assembly is arranged on the outside of the top triangular frame; The quick-assembly component includes a limiting shell, which is fixedly connected to the outside of the top triangular frame. The bottom triangular frame has multiple first through slots inside, and the top triangular frame has multiple second through slots inside. A positioning post is slidably connected inside the first through slot, and a positioning slot is provided on one side of the positioning post.

[0007] As a further description of the above technical solution: The lower surface of the top tripod is fixedly connected to multiple fixing boxes, and the interior of each fixing box is slidably connected to a positioning block.

[0008] As a further description of the above technical solution: One side of the positioning block is fixedly connected to multiple connecting posts and multiple first springs, wherein one end of each of the multiple connecting posts is fixedly connected to a pull bracket, and the multiple first springs are fixedly connected to the inner wall of the fixing box.

[0009] As a further description of the above technical solution: One end of the positioning post is provided with a disassembly assembly, which includes a limiting block. The limiting block is fixedly connected to one end of the positioning post, and a threaded hole is provided on one side of the limiting block.

[0010] As a further description of the above technical solution: The threaded hole is internally threaded with a stud, and a knob is fixedly connected to one end of the stud. The inner wall of the base tripod has multiple threaded holes, and the stud is threaded into the inside of the threaded holes.

[0011] As a further description of the above technical solution: Replacement components are provided at both ends of the support column. The replacement components include two columnar grooves, which are formed at both ends of the support column. Multiple inserts are fixedly connected to one side of the bottom tripod and the top tripod.

[0012] As a further description of the above technical solution: The insertion post has multiple locking holes on one side, and the support post has two square grooves on one side.

[0013] As a further description of the above technical solution: A fixing frame is fixedly connected inside the square groove, and multiple locking rods are slidably connected inside the fixing frame. A limit frame is fixedly connected to the middle of the locking rods, and the limit frame is slidably connected inside the square groove.

[0014] As a further description of the above technical solution: A plurality of second springs are fixedly connected to one side of the limiting frame, wherein the plurality of second springs are fixedly connected to the inner wall of the fixed frame, and one end of the plurality of locking rods is fixedly connected to a straight frame, and the second springs are sleeved on the outside of the locking rods.

[0015] The present invention has the following beneficial effects: 1. This invention, through the setting of the quick-assembly component, places the bottom triangular frame of the second bracket on top of the top triangular frame of the first bracket, facilitating the splicing of the two brackets. The limiting shell facilitates the external limiting of the bottom triangular frame placed on the top triangular frame, while the positioning post inserted into the second through groove facilitates the lateral limiting of the second bracket. With the connection between the positioning block and the positioning groove, the longitudinal limiting of the positioning post is facilitated. This helps to facilitate the quick and stable splicing of the two brackets, thereby reducing the working time spent splicing the two brackets, improving work efficiency, reducing the use of flanges, thus helping to reduce splicing costs, and reducing the phenomenon of difficulty in splicing the two brackets due to missing bolts.

[0016] 2. By setting up a disassembly component, the present invention utilizes the connection between the positioning post and the first through groove, and through the cooperation of the stud and the screw hole, when the positioning post is locked, the positioning post is in a detachable state. Thus, when the bracket is used, the positioning post on the bottom support can be flexibly disassembled according to the usage requirements, which facilitates the bottom triangle of the bottom support to touch the ground in a balanced manner and improves the flexibility of the bracket.

[0017] 3. By replacing the components, this invention utilizes the insertion of the insert post into the columnar groove and the insertion of the locking rod into the locking hole, which facilitates the quick installation of the support post between the bottom and top tripods. This allows the support post to be replaced promptly when cracks or damage occur, ensuring that the entire bracket can always maintain strong support and thus reducing costs by eliminating the need to replace the entire bracket.

[0018] This invention facilitates the rapid and stable assembly of two supports using a quick-assembly component. The bottom triangular frame of the second support is placed on the top triangular frame of the first support. Lateral positioning is achieved using a limiting shell, a positioning post engaging with a second through groove, and a positioning block connecting to the positioning groove, thus providing bidirectional longitudinal and transverse positioning. This reduces assembly time and flange usage, lowering costs. The disassembly component allows for the removal of the positioning post, ensuring the bottom triangular frame of the bottom support maintains balanced contact with the ground and improving flexibility. The replaceable component facilitates quick replacement of damaged support posts. Attached Figure Description

The top triangular frame 3 has multiple second through slots 6 inside to facilitate the insertion of the positioning post 7. The positioning post 7 is slidably connected inside the first through slot 5. The positioning post 7 has a positioning slot 8 on one side to facilitate the insertion of the positioning block 10.

[0023] As attached Figure 3 As shown, multiple fixing boxes 9 are fixedly connected to the lower surface of the top tripod 3. A positioning block 10 is slidably connected inside the fixing box 9 and is inserted into the positioning groove 8. Multiple connecting posts 11 and multiple first springs 13 are fixedly connected to one side of the positioning block 10. The multiple first springs 13 are fixedly connected to the inner wall of the fixing box 9, and the first springs 13 facilitate pushing the positioning block 10.

[0024] As attached Figure 6 As shown, one end of each of the multiple connecting posts 11 is fixedly connected to a pull bracket 12, which facilitates pulling the multiple connecting posts 11. One end of the positioning post 7 is provided with a disassembly assembly, which includes a limiting block 14 to limit the upper part of the positioning post 7. The limiting block 14 is fixedly connected to one end of the positioning post 7. A threaded hole is opened on one side of the limiting block 14, which matches the stud 15. The internal thread of the threaded hole is connected to the stud 15. One end of the stud 15 is fixedly connected to a knob 16, which facilitates turning the stud 15.

[0025] As attached Figure 7 As shown, the inner wall of the base tripod 1 has multiple screw holes 17, and the stud 15 is threaded into the inside of the screw holes 17, which facilitates the locking of the limit block 14.

[0026] As attached Figure 8 As shown, the support column 2 is provided with replacement components at both ends. The replacement components include two columnar grooves 20, which are opened at both ends of the support column 2 to facilitate the insertion of the insertion column 18.

[0027] As attached Figure 7 As shown, multiple insert posts 18 are fixedly connected to one side of both the bottom tripod 1 and the top tripod 3, and are connected to the columnar groove 20. Multiple locking holes 19 are opened on one side of the insert post 18, which are connected to the locking rod 23 to facilitate locking the insert post 18.

[0028] As attached Figure 9 As shown, two square grooves 21 are provided on one side of the support column 2 to protect the second spring 25. A fixed frame 22 is fixedly connected inside the square groove 21. Multiple locking rods 23 are slidably connected inside the fixed frame 22 to facilitate insertion into the locking hole 19. A limit frame 24 is fixedly connected to the middle of the locking rod 23 to limit the movement of the locking rod 23. The limit frame 24 is slidably connected inside the square groove 21. Multiple second springs 25 are fixedly connected to one side of the limit frame 24. The multiple second springs 25 are fixedly connected to the inner wall of the fixed frame 22. The limit frame 24 is used to limit the locking rod 23. A straight frame 26 is fixedly connected to one end of the multiple locking rods 23 for pulling the multiple locking rods 23. The second springs 25 are sleeved on the outside of the locking rods 23 to limit the movement of the second springs 25.

[0029] Working principle: When assembling each standard bracket as a whole, the operator first moves to the height of the bracket to be assembled, and then pulls multiple pullers 12, so that the pullers 12, through the connection of the connecting column 11, drive the positioning block 10 to move into the fixed box 9. The second bracket is lifted by the crane and moved above the first bracket. Then, the positioning column 7 on the second bracket is inserted into the second through groove 6 of the first bracket. The pullers 12 are released. Under the action of multiple first springs 13 being compressed and rebounding, the positioning block 10 will be pushed to move and insert into the positioning groove 8, thereby locking the positioning column 7. At this time, the positioning column 7 is limited laterally by the second through groove 6 and longitudinally by the positioning block 10, which facilitates the quick assembly of the second bracket and the first bracket as a whole. When it is necessary to disassemble multiple positioning posts 7 on the bottom bracket to make the bottom of the bottom triangular frame 1 of the bottom bracket balanced, turn multiple knobs 16 so that the knobs 16 drive the studs 15 to be screwed out of the screw holes 17. At this time, the limiting block 14 is released from the limit. Then move the limiting block 14 up and the limiting block 14 drives the positioning posts 7 to slide away from the first through groove 5, thereby removing multiple positioning posts 7 of the bottom bracket, so that the bottom triangular frame 1 of the bottom bracket can be balanced. When the support column 2 of the bracket becomes cracked or damaged after use and needs to be replaced, first pull the two straight frames 26 inside the multiple support columns 2. When the corresponding multiple locking rods 23 slide inside the fixed frame 22, the limiting frame 24 will slide inside the square groove 21, causing the second spring 25 to be compressed. At this time, one end of the locking rod 23 separates from the locking hole 19 and moves into the square groove 21, so that the insertion post 18 inserted into the columnar groove 20 is released from the limit. Then move the top tripod 3 upward, so that the corresponding multiple insertion posts 18 are separated from the columnar groove 20 at the top of the support column 2, so that the top of the support column 2 is released from the limit. Then move the support column 2 upward, so that the columnar groove 20 at the bottom of the support column 2 is separated from the insertion post 18 on the bottom tripod 1, making it easy to disassemble the support column 2. During installation, the above operations are reversed.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
