Description

Technical Field

[0001] This utility model belongs to the technical field of single-box precast beam dismantling device, and in particular relates to a single-box precast beam anti-tipping frame. Background Technology

[0002] During the dismantling of precast box girders, the dismantled single-cell precast beams need to be hoisted to the ground first. Because the length of the dismantled single-cell precast beams is 30 meters, they cannot be directly hoisted onto the transport vehicle for transportation. Therefore, the dismantled single-cell precast beams need to be cut to reduce their length before being hoisted onto the transport vehicle for transportation.

[0003] However, when dismantling and lowering precast single-cell prefabricated beams to the ground, unbalanced lifting force or uneven ground can easily cause the beams to tip over. Tilted beams cannot be effectively cut, requiring secondary lifting or adjustment to ensure they are placed flat on the ground. This increases construction time and labor costs, leading to reduced construction efficiency.

[0004] Therefore, there is an urgent need for a simple and rationally designed anti-tipping jig for single-cell precast beams to meet the placement requirements after dismantling, prevent the single-cell precast beams from tipping over, facilitate cutting of the single-cell precast beams, avoid secondary lifting, and improve construction efficiency.

[0032] like Figures 1 to 4As shown, this utility model includes a left longitudinal beam 2, a right longitudinal beam 3, two load-bearing crossbeams 1 fixed between the left longitudinal beam 2 and the right longitudinal beam 3 for placing the single-box precast beam 10, a left limiting frame 4 set on the left longitudinal beam 2 and a right limiting frame 5 set on the right longitudinal beam 3, and clamping blocks for clamping the bottom of the single-box precast beam 10 are provided on the two load-bearing crossbeams 1;

[0033] The left limiting frame 4 and the right limiting frame 5 have the same structure. Both the left limiting frame 4 and the right limiting frame 5 include an outer frame fixed on the left longitudinal beam 2 and the right longitudinal beam 3, an inner anti-tilt plate 5-6 fixed on the bearing crossbeam 1, and an upper connecting plate 5-4 and a lower connecting plate 5-5 that are fixedly connected to the outer frame and the inner anti-tilt plate 5-6. The upper connecting plate 5-4 is provided with a lifting lug 1.

[0034] In this embodiment, the outer frame includes a vertical beam 5-3 mounted on the left longitudinal beam 2 and the right longitudinal beam 3, a first inclined beam 5-1 fixedly connected to one side of the vertical beam 5-3, and a second inclined beam 5-2 fixedly connected to the other side of the vertical beam 5-3. One end of the upper connecting plate 5-4 and the lower connecting plate 5-5 is fixedly connected to the inner anti-tilt plate 5-6, and the other end of the upper connecting plate 5-4 and the lower connecting plate 5-5 is fixedly connected to the vertical beam 5-3. The bottom ends of the first inclined beam 5-1 and the second inclined beam 5-2 are both fixedly connected to the top of the left longitudinal beam 2 and the right longitudinal beam 3.

[0035] In this embodiment, the clamping blocks include a left clamping block 7 that clamps the left side of the single-box precast beam 10 and a right clamping block 8 that clamps the right side of the single-box precast beam 10. An adjusting screw 6 is provided in the left longitudinal beam 2 and the right longitudinal beam 3. The left clamping block 7 and the right clamping block 8 are threaded onto the adjusting screw 6. The rotation of the adjusting screw 6 causes the right clamping block 8 to move closer to clamp or move away from clamping to release clamping.

[0036] In this embodiment, the adjusting screw 6 includes an integrally formed left screw part 6-1 and a right screw part 6-2. The left clamping block 7 is threaded onto the left screw part 6-1, and the right clamping block 8 is threaded onto the right screw part 6-2. The inner side of the left longitudinal beam 2 is provided with a left pad 6-3 for mounting the left end of the left screw part 6-1, and the inner side of the right longitudinal beam 3 is provided with a right pad 6-4 for rotating the right screw part 6-2. The right end of the right screw part 6-2, which protrudes from the end of the right longitudinal beam 3, is provided with an adjusting part 6-5.

[0037] In this embodiment, the inner surfaces of the left clamping block 7 and the right clamping block 8 are inclined surfaces adapted to the side surfaces of the single-box precast beam 10, and a silicone pad layer 9 is provided on the inclined surfaces.

[0038] In this embodiment, both the left clamping block 7 and the right clamping block 8 include a lower insert 7-1 and an upper protruding clamping block 7-2 integrally formed with the lower insert 7-1. The lower insert 7-1 is threaded onto the left screw portion 6-1 and the right screw portion 6-2, and both ends of the lower insert 7-1 are embedded in the bearing beam 1. The upper protruding clamping block 7-2 is located between the two bearing beams 1.

[0039] In this embodiment, in actual use, the left longitudinal beam 2, right longitudinal beam 3, load-bearing crossbeam 1, left limiting frame 4, and right limiting frame 5 can all be made of I-beams or H-beams to meet the load-bearing requirements.

[0040] In this embodiment, during actual use, the left longitudinal beam 2 and the right longitudinal beam 3 can be connected to the ground using expansion bolts, improving overall stability. Furthermore, in actual use, concrete can be poured onto the ground, enhancing installation performance.

[0041] In this embodiment, in actual use, there are two left limiting frames 4 and two right limiting frames 5, which are arranged at intervals along the length direction of the left longitudinal beam 2 and the right longitudinal beam 3, so that the clamping block is located between the two left limiting frames 4 and the two right limiting frames 5.

[0042] In this embodiment, during actual use, the left end of the left screw section 6-1 is a smooth rod section, which is convenient to be installed in the left pad 6-3 by rotating through the bearing. The right end of the right screw section 6-2 is a smooth rod section, which passes through the left pad 6-3 by rotating through the bearing and continues to pass through the right longitudinal beam 3.

[0043] In this embodiment, during actual use, left pad 6-3 and left pad 6-3 are provided on the web of the left longitudinal beam 2 and the right longitudinal beam 3 to reinforce both ends of the adjusting screw 6, resulting in good connection stability and thus improving performance.

[0044] In this embodiment, during actual use, the threads of the left screw section 6-1 and the right screw section 6-2 are opposite, so that the adjusting screw 6 rotates, the left clamping block 7 moves along the length direction of the left screw section 6-1, and the right clamping block 8 moves along the length direction of the right screw section 6-2. Then the right clamping block 8 and the right clamping block 8 approach and clamp the left and right sides of the single-box precast beam 10.

[0045] Conversely, when the adjusting screw 6 rotates in the opposite direction, the left clamping block 7 moves in the opposite direction along the length of the left screw part 6-1, and the right clamping block 8 moves in the opposite direction along the length of the right screw part 6-2. Then the right clamping block 8 and the right clamping block 8 move away from each other and release the clamping of the left and right sides of the single-box precast beam 10.

[0046] In this embodiment, during actual use, the adjustment part 6-5 can be adjusted as needed, and can be a handle, rocker, rotating block or hexagonal block, etc., as long as it is easy to adjust.

[0047] In this embodiment, during actual use, the two ends of the lower insert 7-1 are embedded inside the supporting crossbeam 1. The two end faces of the lower insert 7-1 are in contact with the web of the supporting crossbeam 1, the bottom surfaces of the two ends of the lower insert 7-1 are in contact with the top of the lower flange plate of the supporting crossbeam 1, and the top surfaces of the two ends of the lower insert 7-1 are in contact with the bottom of the upper flange plate of the supporting crossbeam 1. This guides and limits the two ends of the lower insert 7-1, improving the accuracy of clamping and adjustment.

[0048] In this embodiment, during actual use, the upper convex clamping block 7-2 is located between the two bearing beams 1, thereby adapting to the inner anti-tilting plate 5-6 and not affecting the adjustment of the left clamping block 7 and the right clamping block 8.

[0049] In this embodiment, during actual use, the inner surfaces of the left clamping block 7 and the right clamping block 8 are inclined surfaces adapted to the side of the single-box precast beam 10, which facilitates better contact with the single-box precast beam 10 for clamping; in addition, the silicone pad layer 9 is provided to prevent slippage and improve the clamping effect.

[0050] In this embodiment, the lower insert 7-1 is set in actual use so that the lower insert 7-1 is threaded onto the left screw part 6-1 and the right screw part 6-2. The two ends of the lower insert 7-1 are embedded in the bearing beam 1 for limiting and guiding, which improves the adjustment accuracy and thus improves the subsequent clamping effect.

[0051] In practical use, multiple anti-tipping frames are arranged along the length of the single-box precast beam 10, and the number of the multiple anti-tipping frames on the left and right sides of the cutting position of the single-box precast beam is the same, so that the force is balanced when the single-box precast beam is cut into two single-box precast beam segments.

[0052] First, the disassembled precast single-box prefabricated beam 10 is placed on multiple anti-tipping jigs, with the bottom of the precast single-box prefabricated beam 10 attached to the load-bearing crossbeam 1 of the anti-tipping jig. Then, the adjusting screw 6 is rotated, the left clamping block 7 moves along the length direction of the left screw part 6-1, and the right clamping block 8 moves along the length direction of the right screw part 6-2. The right clamping block 8 and the right clamping block 8 then move closer to clamp the left and right sides of the precast single-box prefabricated beam 10. After that, the precast single-box prefabricated beam is cut using a cutting device. After the cutting is completed, the adjusting screw 6 is rotated in the opposite direction, the left clamping block 7 moves in the opposite direction along the length direction of the left screw part 6-1, and the right clamping block 8 moves in the opposite direction along the length direction of the right screw part 6-2. The right clamping block 8 and the right clamping block 8 then move away from each other, releasing the clamps on the left and right sides of the precast single-box prefabricated beam 10. The cut precast single-box prefabricated beam segment is then lifted onto a transport vehicle for transportation, improving construction safety.

[0053] In summary, this utility model has a simple structure and reasonable design, which can meet the needs of placing single-cell precast beams after demolition, avoid the overturning of single-cell precast beams, facilitate the cutting of single-cell precast beams, avoid secondary lifting, and improve construction efficiency.

[0054] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
