[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] Reference Figure 1 , Figure 2A tire-type mid-span closure section hanger includes a hanger template 2 arranged below a box beam 1, the hanger template 2 is adapted to the shape of the bottom end of the box beam 1, a support frame 3 is arranged above the box beam 1, the support frame 3 includes two parallel beams 31, two cross braces are arranged in parallel between the two beams 31, and both ends of the cross braces are fixedly connected to the corresponding positions of the two support frames 3, two columns 32 are fixedly installed at corresponding positions below the two beams 31, and an oblique brace is obliquely arranged at both ends of the columns 32 below the two beams 31, one end of the oblique brace is fixedly connected to the beam 31, and the other end of the oblique brace is fixedly connected to the corresponding position of the column 32, a lower beam 31 is arranged between the two columns 32 located on the same beam 31, a lower cross brace is arranged between the two columns 32 located at corresponding positions on the two beams 31, and both ends of the two beams 31 are connected to the hanger template through a hanger rod 4 2 connection, a displacement component 5 is installed at the bottom end of the column 32, which is convenient for driving the hanger template 2 to move. Before the joint is closed, the hanger template 2 and the support frame 3 are built in advance outside the operating line of the box girder 1. At this time, a gap is left between the hanger template 2 and the box girder 1. When the joint needs to be closed, the built hanger template 2 and the support frame 3 are moved to the joint position of the box girder 1 through the displacement component 5 for construction. During construction, the hanger template 2 is fitted with the box girder 1. After the construction is completed, the hanger template 2 is separated from the box girder 1, and the hanger template 2 and the support frame 3 are moved back to the outside of the operating line for removal through the displacement component 5. They can be assembled in advance and removed later, which greatly reduces the time for installation and removal of the hanger template 2 during joint closing, ensures that the installation and reinforcement of the outer mold of the middle span joint section is completed within a skylight point, and is removed outside the operating line, which to a certain extent avoids the risk of debris falling onto the operating line.

[0019] Reference Figure 1 , Figure 2 The displacement assembly 5 includes four tires 51 and a guide member 52 for limiting the moving direction of the tires 51. The four tires 51 are respectively installed at the bottom ends of four columns 32. The guide member 52 includes two guide plates 521 with U-shaped end sections. The two guide plates 521 are arranged in parallel. The guide plates 521 are mounted on two box beams 1 that need to be joined. The two sides of the two tires 51 near the same end on the two cross beams 31 are vertically slidably fitted with the guide plates 521 at the corresponding positions to limit the moving direction of the tires 51.

[0020] Reference Figure 1-Figure 3The displacement assembly 5 also includes a limit piece 53 for limiting the position of the guide plate 521. The limit piece 53 includes four first connecting blocks 531 and two connecting rods 533. The four first connecting blocks 531 are fixedly connected to the sides of the two guide plates 521 facing each other near the two ends. The four first connecting blocks 531 are each provided with a vertical first card slot, and a first card block 532 is inserted into each of the four first card slots. The two connecting rods 533 are respectively located between the two guide plates 521 near the two ends. The two connecting rods 533 are arranged in parallel, and the two ends of the connecting rod 533 are respectively fixedly connected to the two first card blocks 532 located at the same end of the two guide plates 521 to limit the distance between the two guide plates 521 so that the distance between the two guide plates 521 is equal to the distance between the two tires 51 located on the same crossbeam 31. A second connecting block 534 is fixedly installed near the two ends of the sides of the two guide plates 521 facing away from each other. The connecting block 534 is provided with a second vertical slot, and a second card block 535 is inserted in each of the second slots. A threaded telescopic rod 536 is evenly arranged on the side of the second card blocks 535 away from the guide plate 521. One end of the threaded telescopic rod 536 is fixedly connected to the second card block 535 at the corresponding position, and the other end of the threaded telescopic rod 536 is fixedly installed with a connecting seat 537. The connecting seat 537 abuts against the guardrail of the box beam 1 to limit the position of the guide plate 521 on the box beam 1. The threaded telescopic rod 536 and the connecting rod 533 are detachable for easy transportation. After the support frame 3 and the hanger template 2 are installed, the two guide plates 521 are adjusted to the appropriate position, and the support frame 3 is manually pushed to move, and the tire 51 is moved to the guide plate 521. The support frame 3 is manually pushed to move along the long side direction of the guide plate 521 until the tires 51 on the two beams 31 are respectively located on the two box beams 1. At this time, the hanger template 2 is in the joint position for construction.

[0021] Reference Figure 3 A climbing plate 6 is fixedly connected to both ends of the guide plate 521. The end section of the climbing plate 6 is a right triangle, which makes it easier to push the tire 51 onto the guide plate 521.

[0022] The working principle of the embodiment of the present application is: before the joint closing, the hanger formwork 2 and the support frame 3 are built in advance outside the operating line of the box beam 1. When the joint closing is required, the two guide plates 521 are adjusted to the appropriate position, and the support frame 3 is moved by manually pushing the tire 51 to the guide plate 521. The support frame 3 is manually pushed to move along the long side direction of the guide plate 521 until the tires 51 on the two cross beams 31 are respectively located on the two box beams 1. At this time, the hanger formwork 2 is in the joint closing position and construction is carried out. After the joint closing construction is completed, the hanger formwork 2 is separated from the beam body, and then the hanger formwork 2 and the support frame 3 are pushed back to the outside of the operating line for removal. The hanger formwork 2 can be assembled in advance and removed later, which greatly reduces the time for installation and removal of the hanger formwork 2 during the joint closing, ensures that the installation and reinforcement of the outer formwork of the mid-span joint closing section is completed within a skylight point, and the removal is outside the operating line, which to a certain extent avoids the risk of debris falling onto the operating line.
