It does not rely on the holes on the surface of the product and has little impact on the process. At the same time, the hoisting position can be selected according to the actual situation. It is not restricted by the holes, has strong versatility, does not need to be connected to the product, and has no impact on the product structure.

[0015] (2) The steel plates of suspended light steel structure landscape bridges are relatively thin and are easily deformed by compression during the hoisting and turning process. The steel plates are passed through the grooves in the top plate for hoisting and turning. At the same time, the steel wire rope does not hit any parts, and the turning in the air can be achieved. This can avoid product deformation, adapt to different hoisting environments, flexibly select hoisting equipment, and can be reused, saving costs. It can be applied to suspended bridges, such as truss bridges with I-beam structures. BRIEF DESCRIPTION OF THE DRAWINGS

An upper locking member 22 is provided at each of the two ends above the crossbeam, and the upper locking member 22 is composed of an integrally formed upper locking upper portion 221 and an upper locking lower portion 222, and a notch for inserting into the inner end of the top plate 14 is formed between the upper locking upper portion 221 and the upper locking lower portion 222. A lower locking member 23 is provided at each of the two ends of the lower part of the cross beam. The lower locking member 23 is composed of an integrally formed lower locking upper portion 231 and a lower locking lower portion 232. A notch is formed between the lower locking upper portion 231 and the lower locking lower portion 232 for the inner end of the bottom plate 13 to be embedded. The lower locking upper portion 231 is composed of two integrally formed lower locking upper sub-portions. A notch is formed between the two lower locking upper sub-portions for the bottom of the cross beam 11 to be embedded. Fixing plates extending to both sides are provided at the edges of the upper locking upper portion 221, the upper portion 212, the lower portion 214, and the lower locking lower portion 232. The fixing plates at the edges of the upper locking upper portion 221 fit with the fixing plates at the edges of the upper portion 212 and are fixedly connected by bolts 24. The fixing plates at the edges of the lower portion 214 fit with the fixing plates at the edges of the lower locking lower portion 232 and are fixedly connected by bolts 24.

[0035] A single ear hole is opened in the middle of the outer side of one of the ear plates to form the main lifting ear, and an ear hole is opened at each of the two ends of the outer side of the other ear plate to form an auxiliary lifting ear. The ear hole of the main lifting ear is located on the outer side of the beam section, that is, the outer side of the side plate; the two ear holes of the auxiliary lifting ear are respectively located on the outer sides of the top plate and the bottom plate, and one of the ear holes is tilted outward. In order to avoid deformation of the beam section due to collision between the wire rope and the beam section during the turning process, the ear hole of the main lifting ear is located on the outer side of the beam section and is relatively large in size; in order to avoid interference between the wire rope and the beam section during the turning process, the auxiliary lifting ear requires two ear holes and the two ear holes are respectively located on the outer sides of the top plate and the bottom plate; in addition, in order to ensure the strength of the lifting ear and reduce the weight of the lifting ear, while increasing the freedom of rotation of the shackle, one of the ear holes of the auxiliary lifting ear is tilted outward. The main lifting ear mainly plays a lifting role, and the auxiliary lifting ear has a turning function in addition to the lifting function. Such as Fig.14As shown, there are two ear holes in the auxiliary lifting ear, one of which is inclined outward and is located above the other ear hole, hook 2 is hooked in the outward inclined ear hole, hook 1 is hooked in the ear hole in the main lifting ear, hook 1 is the main hook, hook 2 is the auxiliary hook, and the turning process includes: step 1: hook 1 and hook 2 are lifted to the corresponding height at the same time to ensure that the beam section is >500mm from the ground and is lifted horizontally; step 2: hook 1 continues to be lifted to the corresponding height, hook 2 does not move, and turns over 45°; step 3: hook 1 continues to be lifted to the corresponding height, hook 2 does not move, and turns over 90°; step 4: hook 2 is removed, the beam section rotates 180°, and hook 2 is hooked in the other ear hole of the auxiliary lifting ear; step 5: hook 2 does not move, hook 1 falls, and turns over to 135°, step 6: hook 2 does not move, hook 1 continues to fall, and turns over to 180°. The main lifting lug and the auxiliary lifting lug lift the beam section into the air. The main lifting lug is lifted. After the beam section becomes 90 degrees, the main lifting lug is subjected to force. After the beam section rotates 180°, the wire rope of the auxiliary lifting lug is switched to the other side. The main lifting lug descends, the auxiliary lifting lug remains stationary, and the beam section is turned over in the air.

[0036] During installation, the main lifting lug and the auxiliary lifting lug are respectively installed on the web of the outer side of the beam section, close to the web, and the upper locking piece is used to pass through the hole of the curb cover plate at the upper part, and the lower locking piece is used to pass through the bottom of the cross beam at the lower part, and the main lifting lug is connected with the upper locking piece, the lower locking piece, and the auxiliary lifting lug is connected with the upper locking piece, the lower locking piece with bolts. In order to adapt to different web thicknesses, a pad 9 is added at the connection between the main lifting lug and the upper locking piece, the lower locking piece, and the auxiliary lifting lug and the upper locking piece, the lower locking piece, to adjust the gap to meet the different web thicknesses.

[0037] The beam section of the suspended light steel structure landscape bridge is light in weight and has a thin steel plate. The contact areas between the ear plates, upper locking parts, lower locking parts and the web are increased by setting fitting plates extending to both sides on both sides of the edge of the middle part 213, the fitting plates extending to both sides on both sides of the edge of the upper locking lower part 222, and the fitting plates extending to both sides on both sides of the edge of the lower locking upper part 231, thereby preventing the components from being deformed due to too small a contact area during the turning process.
