Words such as "first" and "second" mentioned herein are only used to describe two or more structures or components with the same or similar structures, and do not represent any special limitation on the order.

Please refer to Fig. 1 and Fig. 2. Fig. 1 is a structural schematic diagram of a specific embodiment of the connection structure of the high-altitude steel structure frame beam provided by the utility model, and Fig. 2 is a structural schematic diagram of the alignment plate.

As shown in Figure 1 and Figure 2, the utility model provides a connection structure of high-altitude steel structure frame beams, including two frame beams 1, both frame beams 1 include an upper flange plate 11 and a lower flange plate 12, and the upper flange plate A web 13 is connected between the edge plate 11 and the lower flange plate 12 . It can be understood that among the two frame beams 1, one has been fixed high in the air and is a fixed beam, which is reflected in the attached figure as the frame beam 1 on the left, and the other needs to be hoisted and connected to the fixed beam, which is a butt joint beam. Reflected in the accompanying drawings is the frame beam 1 on the right.

Different from the prior art, the above connection structure may also include an alignment plate 2, one end of the alignment plate 2 is a fixed end portion 2a, and the fixed end portion 2a is fixed to the upper flange plate 11 of one of the two frame beams 1 Or the lower flange plate 12, the other end is a free end 2b, and a first connection hole 211 is provided, and the upper flange plate 11 or the lower flange plate 12 corresponding to the other of the two frame beams 1 is provided with a connecting piece 14.

It should be noted that the above-mentioned "correspondence" corresponds to the installation position of the alignment plate 2; taking the existence of an alignment plate 2 as an example, if the fixed end 2a of the alignment plate 2 is fixed to the upper wing of a frame beam 1 flange 11, the other frame beam 1 should also be the upper flange 11 provided with the aforementioned connector 14, if the fixed end 2a of the alignment plate 2 is fixed to the lower flange 12 of a frame beam 1, then another A frame beam 1 should also be provided with the aforementioned connecting piece 14 on the lower flange plate 12 .

In the docked state, the connecting piece 14 can pass through the first connecting hole 211 to connect the two frame beams 1 through the alignment plate 2, and at this time, the upper flange plates 11 of the two frame beams 1 can abut against each other, and the lower flange The plates 12 can offset each other, and the initial docking positioning of the two frame beams 1 has been completed, so that the occupancy of the hoisting equipment can be released. Compared with the existing technology, the installation of each frame beam 1 can reduce the adjustment and alignment time by at least 20 minutes , so that the mechanical shift and cost input can be greatly reduced.

Moreover, since the initial butt joint positioning of the two frame beams 1 has been completed, the upper flange plate 11 and the lower flange plate 12 of the two frame beams 1 have been offset, and the positions of the two are relatively fixed. At this time, the welding operation is relatively difficult. It is lower, and due to the better working environment, the efficiency of welding can also be improved, and it can also save working time to improve the working efficiency of the entire steel structure project.

In a specific scheme, the two upper flange plates 11 and the two lower flange plates 12 that are in contact with each other can be fixed by welding to form a fully penetrated butt weld, and the alignment plate 2 can ensure that the two frame beams 1 reliable connection between.

It should be pointed out that the two upper wing plates 11 or the two lower wing plates 12 connected by the alignment plate 2 can no longer be welded for secondary fixing, that is, it can also be connected and fixed only by the alignment plate 2, At this time, welding operations can also be reduced to minimize operating time and improve operating efficiency.

The above-mentioned connecting piece 14 may include bolts 141 and nuts 142, both of which may be pre-installed on the frame beam 1, and may also be carried by on-site operators for installation when in use.

For the fixed end part 2a, it needs to be connected with the frame beam 1 in advance. In one scheme, the fixed end part 2a can be connected with the frame beam 1 by means of welding, etc., while in another scheme, the fixed end part 2a is then The detachable connection with the frame beam 1 can be realized through the aforementioned connecting piece 14 and the like. Concretely to the embodiment of the present utility model, it is preferable to adopt a detachable connection scheme. In this way, after the two frame beams 1 are docked and installed, the alignment plate 2 can be removed to facilitate repeated use and save material consumption.
