The utility model is to avoid the shortcomings of the above-mentioned prior art, and provides a lap joint structure for assisting the rapid hoisting of high-rise steel girders, so that the hoisting process of high-rise steel girders is fast and efficient, the construction quality is guaranteed, and the hoisting equipment is improved. The circulation process, improve equipment utilization

The utility model adopts following technical scheme for solving technical problems:

The utility model assists the fast hoisting of high-rise steel beams. For the structural form of erecting steel beams between the first steel column and the second steel column, the structural characteristics of the utility model are: the side wall of the second steel column The first cantilever is welded on the top, and the second cantilever is welded on the side wall of the second steel column. The steel beam is connected with the first cantilever by the first end of the steel beam, and the second cantilever is connected by the second end of the steel beam. Beam docking; at the butt joint position between the steel beam and the first cantilever beam, the first transition plate is welded on the upper flange plate of the steel beam, and the first transition plate is placed on the upper flange plate of the first cantilever beam, so that The upper flange plate of the first cantilever beam forms a temporary support for the steel beam through the first transition plate; at the butt joint position of the steel beam and the second cantilever beam, a second transition plate is welded on the upper flange plate of the steel beam, and the second transition plate is welded with the first transition plate The second transition plate is placed on the upper flange plate of the second cantilever beam, and the upper flange plate of the second cantilever beam forms a temporary support for the steel beam through the second transition plate.

The feature of the lap joint structure of the utility model for assisting the fast hoisting of high-rise steel girders also lies in: the butt joint between the first end of the steel girder and the first cantilever, and the butt joint between the second end of the steel girder and the second cantilever All are bolted connections on the web using connecting plates.

Compared with the prior art, the beneficial effects of the utility model are reflected in:

The utility model realizes the temporary support of the steel beam by the first and second cantilever beams by setting the first transition plate and the second transition plate, so that the hoisting equipment can be withdrawn in advance, and the utilization of the hoisting equipment can be greatly improved rate, speed up the construction progress, and ensure the quality of the project.

Referring to Fig. 1, Fig. 2 and Fig. 3, the overlapping structure of auxiliary high-rise steel girder fast hoisting in the present embodiment is for the structural form of erecting steel girder 5 between the first steel column 1 and the second steel column 2, in the The first cantilever 3 is welded on the side wall of the second steel column 2, and the second cantilever 4 is welded on the side wall of the second steel column 2. The steel beam 5 is based on the first end of the steel beam and the first cantilever 3 Docking, with the second end of the steel beam docked with the second cantilever beam 4; at the butt joint position of the steel beam 5 and the first cantilever beam 3, weld the first transition plate 8 on the steel beam upper flange plate 9, and use the Said first transition plate 8 rides on the first cantilever beam upper flange plate 6, forms temporary support to steel beam 5 with said first cantilever beam upper flange plate 6 through first transition plate 8; Between said steel beam 5 and the second At the butt joint position of the cantilever beam 4, a second transition plate 10 is welded on the steel beam upper flange plate 9, and the second transition plate 10 is placed on the second cantilever beam upper flange plate 7, and the second cantilever beam upper flange plate 7 Form a temporary support for the steel beam 5 through the second transition plate 10.

In specific implementation, the butt joint between the first end of the steel beam and the first cantilever beam 3, and the butt joint between the second end of the steel beam and the second cantilever beam 4 are all implemented on the web by using the connecting plate 11 to implement bolted connection .
