Specific embodiment
As illustrated, a kind of steel mesh crane span structure, including some U-girders 1, and be fixedly connected on some vertical on U-girder 1
To muscle 2, U-girder 1 is located at the inner side of longitudinal rib 2 with the tie point of longitudinal rib 2；Steel mesh crane span structure at least one end is to be provided with two
The head end of root U-girder 1 closer to the distance, one section of longitudinal rib 2 being connected with two U-girders 1 of head end curves inwardly to form recessed
Groove causes that two U-girders 1 of head end are in the groove of longitudinal rib 2, i.e. two U-girders 1 of head end and this section of groove segment of longitudinal rib 2
Tie point be located at the outside of longitudinal rib 2；The groove segment of longitudinal rib 2 is located at the U of conventional crane span structure end when being connected with conventional steel mesh crane span structure
The inner side of shape crossbeam 3, it is recessed that the U-girder 3 of conventional crane span structure end is all located at longitudinal rib 2 as the U-girder 1 of steel mesh gantry middle portion
The outside of groove section, i.e., conventional steel mesh crane span structure end U-girder 3 is located at the groove segment of longitudinal rib 2 with the tie point of the groove segment of longitudinal rib 2
Outside so that the groove segment of longitudinal rib 2 can coordinate with the 3 beam grafting of horizontal stroke of the U-shaped of conventional steel mesh crane span structure end；
Further, the part that two U shapes crossbeams of steel mesh crane span structure head end, 1 liang of side is located between adjacent two longitudinal ribs 2 has
The arched part in outside is convex to, arched part spacing mutually with 1 liang of side of U-girder of conventional steel mesh crane span structure end can be prevented
Abjection；
Yet further, the part that two bases of U shapes crossbeam 1 of steel mesh crane span structure head end are located between adjacent two longitudinal ribs 2 also has
There is the arched part for being convex to outside, arched part spacing mutually with the base of U-girder 1 of conventional steel mesh crane span structure end can be prevented
Abjection；
The outside arched part of two U-girders of head end 1 arches upward highly consistent with the outside height of longitudinal rib 2；Steel mesh crane span structure head end two
The distance between root U-girder 1 closer to the distance is slightly less than U-girder diameter so that conventional steel when conventional steel mesh crane span structure is connected
The U-girder 1 in bridge frame end portion can realize that interference fit is connected by certain elastic deformation, to improve connection reliability；U
Shape crossbeam 1 is circle with the section of longitudinal rib 2.
The steel mesh crane span structure of practicality example one of the invention, two U-shapeds closer to the distance that head end is in longitudinal rib groove segment are horizontal
Beam blocks the U-girder of conventional steel mesh crane span structure end, and by the tight spacing U for blocking conventional steel mesh crane span structure end of interference fit
Shape crossbeam, will not loose or dislocation, connection reliability.
Further, the steel mesh crane span structure of present invention practicality example two, head end two side of U-girder two, bottom closer to the distance
The part that side is located between adjacent two longitudinal ribs 2 all has the arched part for being convex to outside, and arched part blocks conventional steel mesh
The side of crane span structure, base so that the both sides of U-girder 1 of two U-girders closer to the distance of head end and conventional steel mesh crane span structure end
Side is spacing mutually to prevent abjection, and connection is reliable.
Steel mesh crane span structure of the invention, can set two U-girders closer to the distance and block routine in crane span structure main body head end
The U-girder of steel mesh crane span structure end, end is using the U-girder as conventional steel mesh crane span structure and longitudinal rib structure, two sections of bridges
Frame body head end and end are worked in coordination grafting, and two U-girders closer to the distance of head end pass through the tight limiting card of interference fit
The firmly U-girder of end；Uniformity is good, easy for installation；Two U-shapeds closer to the distance can also be all set at crane span structure main body two ends
Crossbeam, two ends coordinate socket connection with the U-girder of conventional steel mesh crane span structure one end simultaneously.
Steel mesh crane span structure of the invention, without setting connection sheet in addition, installs easy to connect, light weight small volume, and connection can
Lean on, installation and transportation are convenient, amount of parts is few, manufacturing process is simple, and the engineering construction time is short, high financial profit.
