[0002] A steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. Welds, bolts or rivets are usually used to connect between each component or part. When installing a steel structure, due to the extremely heavy weight of each component, a hoisting device needs to be used for auxiliary installation.

[0003] When the existing steel structure hoisting device for construction engineering is in use, the same hoisting device can only hoist I-beams of one specification, and the scope of use is limited. The existing hoisting is carried out by two long ropes, and the fixing effect of this method is not good. The steel structure is prone to slipping and falling off, thus causing potential safety hazards. Content of the Utility Model

[0004] The purpose of the utility model is to provide a connecting and fixing device for hoisting a steel structure used in construction, so as to solve at least any one of the problems mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A connecting and fixing device for hoisting a steel structure used in construction, including two clamping and fastening components, an I-beam and a lifting and connecting component.

The connecting walls of the two T-shaped sliding plates are slidably connected in the limiting sliding groove and the bottom of the connecting wall of the T-shaped sliding plate is connected to the top wall of the top plate of the U-shaped placing frame. Threaded holes are arranged at positions close to both ends in the middle of the top walls of the fixing walls of the two T-shaped sliding plates, and second threaded rods are threadedly connected in the threaded holes. A first pressing plate is arranged at one end of the second threaded rod, and limiting telescopic rods connected to the bottom walls of the fixing walls of the T-shaped sliding plates are arranged at positions close to both sides of the top wall of the first pressing plate. A threaded cylinder is embedded between the middle of the connecting wall of the T-shaped sliding plate and the middle position of the top wall of the top plate of the U-shaped placing frame, and a first threaded rod is threadedly connected to the top wall of the fixing wall of the T-shaped sliding plate from the threaded cylinder. A second pressing plate matching the limiting groove is arranged at one end of the first threaded rod inside the U-shaped placing frame, and the second pressing plate is slidably connected between one side adjacent to the limiting groove and the limiting groove. The I-shaped opening of the I-beam is respectively placed on the top walls of the bottom plates of the adjacent U-shaped placing frames. The lifting and connecting component is connected to both sides of the two fixing plates.

[0006] Preferably, the four U-shaped placement racks have the same specifications.

The two U-shaped placement racks 2 are arranged below the fixed plate 9 and the U-shaped openings of the two U-shaped placement racks 2 are adjacent. A limit groove 14 is provided on one inner side wall of the U-shaped placement rack 2, and a limit sliding groove 4 is provided on the top wall of the fixed plate 9. The connecting walls of the two T-shaped sliding plates 8 are slidably connected in the limit sliding groove 4, and the bottom of the connecting wall of the T-shaped sliding plate 8 is connected to the top wall of the top plate of the U-shaped placement rack 2. Threaded holes are provided in the middle of the top walls of the fixed walls of the two T-shaped sliding plates 8 near both ends, and second threaded rods 7 are threadedly connected in the threaded holes. A first pressing plate 10 is provided at one end of the second threaded rod 7, and limit telescopic rods 13 connected to the bottom walls of the fixed walls of the T-shaped sliding plates 8 are provided at positions close to both sides of the top wall of the first pressing plate 10. A threaded cylinder 15 is embedded between the middle of the connecting wall of the T-shaped sliding plate 8 and the middle position of the top wall of the top plate of the U-shaped placement rack 2, and the threaded cylinder 15 is threadedly connected to a first threaded rod 3 from the top wall of the fixed wall of the T-shaped sliding plate 8. A second pressing plate 11 matching the limit groove 14 is provided at one end of the first threaded rod 3 inside the U-shaped placement rack 2, and the side of the second pressing plate 11 adjacent to the limit groove 14 is slidably connected to the limit groove 14. The I-shaped opening of the I-beam 12 is respectively placed on the top walls of the adjacent bottom plates of the U-shaped placement racks 2, and the lifting connection component is connected to both sides of the two fixed plates 9.

[0020] When it is necessary to hoist the I-beam 12, the staff slides the two T-shaped slides 8 to both sides on the limiting slide grooves 4 on the fixed plate 9 respectively. After adjusting the position, the I-shaped mouth of the I-beam 12 is placed on the bottom plate of the U-shaped placement frame 2, and then the two T-shaped slides 8 are slid toward the middle to make the U-shaped placement frame 2 close to the I-beam 12. Then, the second threaded rod 7 on the T-shaped slide 8 is screwed. Due to the limiting effect of the limiting telescopic rod 13, the second threaded rod 7 drives the first pressing plate 10 to move downward and be fixed on the fixed plate 9. At this time, the T-shaped slide 8 is firmly fixed by the second threaded rod 7 It cannot be moved, and the clamping of the I-beam 12 by the C-shaped placement frame 2 is completed. Then the first threaded rod 3 on the T-shaped slide 8 is twisted to rotate in the threaded cylinder 15. Since one side of the second pressing plate 11 is limited by the limiting groove 14 on the C-shaped placement frame 2, the first threaded rod 3 drives the second pressing plate 11 to move downward to press the I-beam 12 tightly against the bottom plate of the C-shaped placement frame 2, completing the fixation of the I-beam 12. After both ends of the I-beam 12 are hoisted, the hoisting rope is tied to the fixing ring 5, and then the hoisting ring 6 is installed on the hoisting vehicle, and the I-beam 12 can be hoisted.
