Description
Technical Field
[0001] The utility model relates to the technical field of hoisting and installation of steel structure beams. Background Art
[0002] In steel structure buildings, steel beams need to be hoisted and connected to steel columns with high-strength bolts. During this process, due to the factor of working at height, the ends of the steel beams shake, making it difficult to align the ends of the steel beams with the connection points to be connected. The reference of the steel beam node after installation Figure 1 , which Figure 1 includes a steel column, a cantilever, and a steel beam. The cantilever is a short-arm structure extending from the steel column and is also an I-beam. The cantilever and the steel beam are quickly fixed by a combination of connecting plates and welding. Specifically, the web position is fixed with connecting plates and high-strength bolts, and the flange position is connected by welding. In the alignment of the above-mentioned steel beam and cantilever, there is a problem that it is difficult to align the steel beam and the cantilever. Summary of the Utility Model

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:
[0005] An auxiliary device for hoisting and installing steel beams in prefabricated buildings, the whole device is a stamping formed body of a steel plate with a thickness of not less than two centimeters and is welded with rib plates. Its characteristics are: the middle of the auxiliary device is an arched structure, and the two ends of the arched structure are respectively a fixed flat plate and a cantilever flat plate. Among them, bolt holes are provided at the fixed flat plate, and the fixed flat plate and the cantilever flat plate are in the same plane. The fixed flat plate is temporarily fixed at the end of the I-shaped steel beam in the hoisting state with high-strength bolts, and the cantilever flat plate and the arched structure extend to the outer end of the I-shaped steel beam and form a cantilever structure.
[0006] Further, six groups of high-strength bolts are provided between the fixed flat plate and the I-shaped steel beam.
[0007] Further, the rib plates are located inside or outside the arched structure part.
[0008] Further, a lifting ring is welded on the back of the auxiliary device.
[0009] The beneficial effects of the utility model are:

[0018] Reference Figures 2 to 5, it shows an auxiliary device for hoisting and installing steel beams of prefabricated buildings and its using process. The whole device is made of steel structure, integrally formed by stamping a thick steel plate with a thickness of not less than 2 cm, and rib plates are welded to improve the overall stiffness. Specifically, the middle of this auxiliary device is an arched structure 10, and both ends of the arched structure are flat structures. For the convenience of description, one of the flat structures is defined as the fixed flat plate 20, and the other flat plate is the cantilever flat plate 30. At least four bolt holes 21 are provided at the fixed flat plate 20. For example, six bolt holes are shown in the illustration of this embodiment. This fixed flat plate 20 is pre-assembled with the I-shaped steel beam in the hoisting state. The so-called pre-assembly means that this fixed flat plate is fixed on the I-shaped steel beam 00 through six groups of high-strength bolts 50, and the cantilever flat plate 30 and part of the arched structure extend to the outer end of the I-shaped steel beam 00, forming an arched cantilever structure. Then, during the butt-joint process of the I-shaped steel beam, it can be quickly and conveniently placed on the installation point of the cantilever 01 through the end cantilever structure, and the I-shaped steel beam can be quickly placed in place through this cantilever structure. After being placed in place, since the I-shaped steel beam and the installation point are partially attached to each other, the I-shaped steel beam does not shake, thus solving the problem of the shaking of the I-shaped steel beam relative to the connection point during the installation of the connecting plate.
[0019] To improve the stiffness of this device, rib plates 40 are welded on the inner side or the outer side of the arched structure part. The existence of this rib plate makes the arched structure not easily deformed.
[0020] After the I-shaped steel beam 00 is temporarily positioned, the web of the I-shaped steel beam is quickly fixed using the connecting plate 02, and then the upper and lower flange plates of the I-shaped steel beam are quickly fixed by welding or bolting. Finally, the six bolts on this device are removed, and this device is taken off for turnover.
[0021] Furthermore, a lifting ring 60 is welded on the back of this device for auxiliary lifting during the disassembly and assembly process, such as tying a safety rope to meet the safety requirements for high-altitude operations.
[0022] The above-described embodiments are only used to describe the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those skilled in the relevant art to the present invention should all fall within the protection scope determined by the claims of the present invention.
