[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figure 1 and Figure 2 As shown in Embodiment 1, a double-layer beam transverse reinforcement device includes: a reinforcement connecting hook 1 and a connecting sleeve 2; there are two reinforcement connecting hooks 1, which are respectively set at both ends of the connecting sleeve 2. The inner walls of both the left and right ends of the connecting sleeve 2 are threaded, and the threads at both ends of the connecting sleeve 2 are oriented in opposite directions. The reinforcement connecting hook 1 can be connected to the pre-embedded steel bars.

[0024] When in use, hook the reinforcing connection hook 1 on one side to the embedded steel bar on the right side, rotate the connecting sleeve 2 so that the reinforcing connection hook 1 that hooks out the embedded steel bar moves toward the connecting sleeve 2. At this time, the reinforcing connection hook 1 that does not hook the embedded steel bar will move toward the reinforcing connection hook 1 that hooks the embedded steel bar and hook the left side of the embedded steel bar, so that the embedded steel bars on both sides are fixedly connected, achieving the reinforcing connection of the double-layer box girder and preventing the box girder from tilting and overturning.

[0025] A threaded rod 1-1 is fixedly installed at the end of the reinforcing connecting hook 1, and the threaded rod 1-1 is threadedly connected to the end of the connecting sleeve 2.

[0026] When the reinforcing hook 1 on one side hooks the embedded steel bar on the right side, the connecting sleeve 2 is rotated. Because the reinforcing hook 1 is restricted by the embedded steel bar, the threaded rod 1-1 will move towards the connecting sleeve 2 when the connecting sleeve 2 is rotated, and the reinforcing hooks 1 on both sides will move closer to each other, so that the embedded steel bars on both sides are fixedly connected, achieving the reinforcement connection of the double-layer box girder and preventing the box girder from tilting and overturning.

[0027] like Figure 3 and Figure 7 As shown, in Embodiment 2, there are two reinforcing connecting hooks 1 located on one side of the connecting sleeve 2. The two reinforcing connecting hooks 1 are installed to rotate relative to each other. A rotating rod 1-2 is fixedly installed at the end of the reinforcing connecting hook 1. A movable frame 3 is provided on the outside of the reinforcing connecting hook 1.

[0028] When the two reinforcing hooks 1 rotate, they can hook onto two adjacent pre-embedded steel bars on the same side, thus achieving the pre-fixation of the reinforcing hooks 1. After the reinforcing hooks 1 are pre-fixed, the movable frames 3 on both sides move closer to each other, so that the pre-embedded steel bars on both sides are fixedly connected, and the connection between the reinforcing hooks 1 and the pre-embedded steel bars is more stable.

[0029] The reinforcing connecting hook 1 is rotatably installed at the end of the movable frame 3. The outer wall of the reinforcing connecting hook 1 contacts the inner wall of the movable frame 3. A threaded sleeve 3-1 is fixedly installed on the outer wall of the movable frame 3. The threaded sleeve 3-1 is threadedly connected to the end of the connecting sleeve 2.

[0030] When the reinforcing hook 1 on one side hooks the adjacent embedded steel bar on the right side, the connecting sleeve 2 is rotated. Because the reinforcing hook 1 is restricted by the embedded steel bar, the threaded sleeve 3-1 will move towards the connecting sleeve 2 when the connecting sleeve 2 is rotated, and the moving frames 3 on both sides will move closer to each other, making the connection between the reinforcing hook 1 and the embedded steel bar more stable.

[0031] A movable block 3-2 is slidably installed inside the movable frame 3. A sliding rod 3-4 is fixedly installed on the movable block 3-2. The sliding rod 3-4 passes through the outer wall of the movable frame 3 and is slidably installed inside the threaded sleeve 3-1.

[0032] When the reinforcing connecting hook 1 rotates, it can drive the two rotating rods 1-2 to move closer to each other, move the moving block 3-2 towards the connecting sleeve 2, and slide the sliding rod 3-4 into the threaded sleeve 3-1. Since the sliding rod 3-4 slides inside the threaded sleeve 3-1, the moving block 3-2 can remain stable when moving.

[0033] The outer surface of the movable block 3-2 is in contact with the outer surface of the rotating rod 1-2. A spring 3-3 is sleeved on the outside of the sliding rod 3-4. The two ends of the spring 3-3 are respectively fixedly installed on the outer surface of the movable block 3-2 and the inner wall of the movable frame 3.

[0034] When the moving block 3-2 moves, it can compress the spring 3-3. When the spring 3-3 is no longer under force, the spring 3-3 resets, causing the moving block 3-2 to reset. When the moving block 3-2 resets, it can hold the angle between the two rotating rods 1-2 and cause the two reinforcing connecting hooks 1 to close, allowing the reinforcing hooks to be removed from the adjacent embedded steel bars.

[0035] The upper and lower ends of the movable frame 3 are provided with movable plates 4. Movable rods 4-1 are fixedly installed at both ends of the movable plates 4. The outer surface of the movable rods 4-1 contacts the two sides of the movable frame 3. The outer wall of the threaded sleeve 3-1 is threaded with a rotating ring 5. The end of the movable plate 4 away from the movable plate 4 is rotatably installed on the rotating ring 5.

[0036] When the movable plate 4 moves, it can drive the movable rod 4-1 to move. When the movable rod 4-1 moves, it can contact the rotating rod 1-2 and close the two rotating rods 1-2. At this time, the reinforcing connection hook 1 unfolds and hooks the pre-embedded steel bar, so that the reinforcing connection steel bar is pre-fixed on the pre-embedded steel bar.

[0037] The outer surface of the rotating ring 5 is provided with a rotating groove 5-1, and a sliding block 4-2 is fixedly installed at the end of the moving plate 4 away from the moving frame 3. The sliding block 4-2 is slidably installed in the rotating groove 5-1.

[0038] The rotating ring 5 is moved on the threaded sleeve 3-1. When the rotating ring 5 moves, it can drive the sliding block 4-2 to move. When the sliding block 4-2 moves, it can drive the moving frame 3 to move, causing the moving rod 4-1 to move. Since there is a rotating groove 5-1, the moving rod 4-1 is in contact with the two sides of the moving frame 3. When the rotating ring 5 rotates, the sliding block 4-2 will slide in the rotating groove 5-1, so that the moving plate 4 will not flip.

[0039] Compared to Embodiment 1, Embodiment 2 has the following advantages: when hooking the pre-embedded steel bars, the closed reinforcing connection hook 1 can be placed between adjacent pre-embedded steel bars. The rotating rings 5 ​​on both sides are rotated to unfold the reinforcing connection hooks 1 on both sides and hook the pre-embedded steel bars. The connecting sleeve 2 is rotated to bring the reinforcing connection hooks 1 on both sides closer to each other, which has a pre-fixing effect. This makes it more convenient to connect the pre-embedded steel bars on both sides. At the same time, hooking the pre-embedded steel bars on both sides is more stable than hooking a single pre-embedded steel bar.

[0040] During disassembly, simply rotate the rotating ring 5 to close the reinforcing connection hook 1, making it easy to remove from the embedded steel bar.

[0041] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
