The specific embodiment
Below in conjunction with accompanying drawing, with embodiment, the utility model is described in further detail.
The part of precasting steel frame member except strengthening chord member that the utility model provides as shown in Figure 1, plane frame 1 is wherein used two upper chords 2 and two lower chords 3 as the basic framework member, and use vertical and oblique connecting rod 4 that upper chord and lower chord are connected to one, between two upper chords and two lower chords, by connector, be welded as a whole, and be provided with Connection Block 6, have chord bolt hole 7 on Connection Block 6, strengthening chord member uses bolt to be fixed together by chord bolt hole 7 and two upper chords 2 or lower chord 3, connection that can be more firm and to bear power stronger.In addition, runner bearing 14 adopts the mode of welding to be installed on the lower chord 3 of mobile truss end plane truss 1.The precasting steel frame member is assemblied to form by single plane frame 1, and plane frame 1 length and width size is generally 3m * 1.5m, when construction, can carry out on-site consolidation according to the size of factory building span.When mounted, the plane frame l of end is with runner 5, and such precasting steel frame member can be put in factory building two across a crane girder top flange, by connection support, tie-rod forms the support of space truss as the spatial operation platform.
The two ends of upper chord 2 and lower chord 3 also have famale connector 8 and the male contact 9 of coupling mutually, have truss on joint and connect pin-and-hole 10, for connecting adjacent two truss.Connection Block 6, for the steel plate with circular hole, also is provided with a plurality of bolts hole 13, crossbeam backing plate 11 on described upper chord 2 or lower chord 3, middle bolt hole l3 is for double or arrange truss more and connect with internode, by the bolt hole 13 at two ends across internode connection use.When many row's truss are done beam or post use, can reinforce with bracing frame the junction surface of upper and lower two joint truss.Crossbeam backing plate 11 is provided with tenon 12, the position in the plane in order to fixed cross beam.
The connecting rod 4 of plane frame 1 is all made with the I-shaped steel, and the vertical connecting rod 4l that connecting rod can be divided into vertical connection upper chord, lower chord reaches and upper chord, the angled oblique connecting rod 42 joined of lower chord.
After completing the splicing of truss, set up the steel pipe operating platform on mobile joist body, the operating platform height need to be determined according to practice of construction.Set up the support of 2 fixed pulleys at the edge of operating platform, according to the material weight of construction handling, determine specification, the size of using fixed pulley, adopt rope made of hemp handling during with fixed pulley.The runner 5 that mobile truss body utilizes runner bearing on end plane truss 1 14 to install, moved, thereby reached the effect of full-scale construction.This support body surrounding is set up guard rail, sets up two higher fulcrums at the two ends of support body, between two fulcrums, hangs cable rope, when the workman constructs on top, safety belt is all hung on this cable rope and moves, thereby effectively avoided the danger of falling from high altitude.When moving this support body, needs enter another across when construction, the scaffold of first dismantling operation platform, and rear recycling mobile crane winches to this support body integral body at the construction space place of another identical span, has realized comprehensively, quick construction.
Above explanation is only to explanation of the present utility model; make those of ordinary skills can accurately implement this programme; but be not to restriction of the present utility model; those skilled in the art can make to the present embodiment the modification that there is no creative contribution as required after reading this manual, all belong to claim protection domain of the present utility model.
