Simply, crane span structure attachment structure quick and easy for installation.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：
A kind of crane span structure attachment structure, including the first crane span structure and the second crane span structure, on two side plates of first crane span structure respectively
Be welded with the plugboard parallel with side plate, the plugboard extend one end of the first crane span structure and on extension equidistantly
Ground is provided with multiple fins, neck is formed between adjacent two fins, the fin is perpendicular to the side of plugboard, the fin
Tilted to the other end of the first crane span structure, be respectively welded on two side plates of second crane span structure and be fixed with U-shaped board, U-shaped board and the
The inserting groove coordinated with plugboard grafting is formed between the side plate of two crane span structures, is provided with fin corresponding to plugboard in the U-shaped board
One side be provided with shell fragment, the shell fragment is parallel with fin, and first crane span structure and the second crane span structure pass through plugboard and grafting
The grafting cooperation of groove and shell fragment and neck snap fit attachment fixation.
Wherein, U-shaped joint-cutting is offered in the U-shaped board, joint-cutting portion enclosed is formed to inserting groove inner bending
The shell fragment.
Wherein, the top surface of the fin is arc surface.
Wherein, the fin is integrally formed with plugboard.
The beneficial effects of the utility model are：It is different from prior art, crane span structure attachment structure provided by the utility model,
Two adjacent crane span structures snap fit attachment fixation by plugboard and the grafting cooperation of inserting groove and shell fragment and neck, exempt from
The substantial amounts of union piece such as bolt, jam nut, lock washer and cover buckle is removed, without opening up bolt on the side plate of crane span structure
Mounting hole, the overall construction intensity of crane span structure is improved, as long as by plugboard alignment inserting groove insertion during installation, it is easy for installation
Fast, structure is firm.

Embodiment
For detailed description technology contents of the present utility model, the objects and the effects, below in conjunction with embodiment and match somebody with somebody
Accompanying drawing is closed to be explained.
It refer to shown in Fig. 1 to Fig. 4, the crane span structure attachment structure of the utility model embodiment, including the first crane span structure 1 and second
Crane span structure 2, it is respectively welded on two side plates of first crane span structure 1 and is fixed with the plugboard 3 parallel with side plate, the plugboard 3
Extend one end of the first crane span structure 1 and multiple fins 30 are equally spacedly provided with extension, between adjacent two fins 30
Neck 31 is formed, the fin 30 tilts perpendicular to the side of plugboard 3, the fin 30 to the other end of the first crane span structure 1, institute
State to be respectively welded on two side plates of the second crane span structure 2 and be fixed with U-shaped board 4, between the side plate of the crane span structure 2 of U-shaped board 4 and second formed with
The inserting groove 40 that the grafting of plugboard 3 coordinates, plugboard 3 is corresponded in the U-shaped board 4 is provided with the one side of fin 30 and be provided with shell fragment
41, the shell fragment 41 is parallel with fin 30, and the crane span structure 2 of the first crane span structure 1 and second is inserted by plugboard 3 and inserting groove 40
Connect cooperation and shell fragment 41 and neck 31 snaps fit attachment fixation.
Operation principle of the present utility model is as follows：
During installation, the inserting groove 40 that the plugboard 3 of the first crane span structure 1 is aligned to the second crane span structure 2 inserts, convex in insertion process
Rib 30 can promote shell fragment 41 to bring it about upward elastic deformation, fin 30 is passed through shell fragment 41, and arrive neck 31
Shell fragment 41 can be inserted in neck 31 under itself rebound effect during position, formed and be clasped with neck 31.Therefore in plugboard 3
