Further preferably, described I-steel is replaced by fine strain of millet body, and described beam body includes two webs be arrangeding in parallel and the upper cover plate covering web and lower cover composition, and the width of described upper cover plate and lower cover is all higher than the width of two web spacings.
Further preferably, between angle steel with beam body, the sketch plate by arranging is connected, and the otic placode of two projections is arranged at described sketch plate top, and bottom is provided with and the draw-in groove of beam body first half cross-sectional area same shape, angle steel is fixing to be welded on otic placode, and the beam body first half is fixing to be welded in draw-in groove.
This utility model intensity is reliable, good stability, and in use front face area is little, vertical stiffness and horizontal rigidity disclosure satisfy that use, and deadweight is lighter.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation,
Fig. 2 is beam body structural representation in this utility model,
Fig. 3 is sketch plate structural representation in this utility model.
Drawing illustrates: 1, outside framework, 2, I-steel, 3, connector, 4, upper frame, 5, underframe, 6, head rod, 7, the second connecting rod, 8, cross tube, 9, sheer pole, 10, beam body, 11, upper cover plate, 12, lower cover, 13, web, 14, sketch plate, 15, otic placode, 16, draw-in groove, 17, connecting plate, 18, riser.
Detailed description of the invention
The technical solution of the utility model is described in detail in conjunction with accompanying drawing, a kind of Lattice Crane girder, including outside framework 1, the I-steel 2 immediately below outside framework 1 centre and multiple connector 3 being uniformly arranged between framework and I-steel 2 along outside framework 1 length direction it is arranged at along outside framework 1 length direction, described outside framework 1 includes upper frame 4, underframe 5 and head rod 6 form, upper frame 4 is made up of the second cross tube 8 that connecting rod 7 connects and two be arranged in parallel by inside two ends, underframe 5 is made up of the second sheer pole 9 that connecting rod 7 connects and two be arranged in parallel by inside two ends, cross tube 8 and sheer pole 9 are by being welded in riser 18 both sides channel-section steel composition in form mouth to mouth；Described second connecting rod 7 is made up of the channel-section steel welded in form mouth to mouth；The plurality of head rod 6 one end being made up of the channel-section steel welded in form mouth to mouth is vertically installed in cross tube 8 lower surface, and the other end is vertically installed in sheer pole 9 upper surface, and is uniformly distributed on the length direction of framework；Described connector 3 is made up of two two angle steel in back-to-back form, and one end of angle steel is connected to the lower surface of cross tube 8 by connecting plate 17, and the other end is connected to I-steel 2 upper surface；Another angle steel one end is connected to the lower surface of another cross tube 8 by connecting plate 17, and the other end is connected to I-steel 2 upper surface；This structure in use front face area is little and deadweight is relatively light, and vertical stiffness and horizontal rigidity disclosure satisfy that use.
Described I-steel 2 is replaced by fine strain of millet body 10, described beam body 10 includes that two webs 13 be arrangeding in parallel and upper cover plate 11 and the lower cover 12 covering web 13 form, the width of described upper cover plate 11 and lower cover 12 is all higher than the width of two web 13 spacings, by being replaced I-steel by beam body 10, when lower cover 12 hangs electric block, it is ensured that the intensity of electric block operation and downward tension.
