Description
Technical field
The present invention relates to a kind of special hanger and using method of steel beam column, specifically a kind of using method of fast hoisting steel girder member bar, belongs to road and bridge construction field.
Background technology
Along with developing rapidly of road traffic, the phenomenon that overhead railway and sky way cross over Existing Railway Bridges or current highway and bridge gets more and more.Due to by works under line and circuit overall height control with affect, overpass beam often adopts Steel truss structure, to meet the designing requirement of circuit.Steel truss girder is assembled by the steel rod elements of various model, lightweight then tens tons of rod member, heavy then tens tons, how quick and stable steel girder member bar is lifted into design and installation position, be a key link of steel truss girder construction.
The construction method of current steel girder member bar lifting adopts wire rope binding lifting, namely when lifting steel girder member bar, in advance at steel girder member bar suspension centre place parcel polybag, steel girder member bar is prevented when lifting by wire rope greasy dirt with this, then bundle at suspension centre place with wire rope, adopt U-shaped ring to connect, then complete lifting installation with lifting machine.More hidden danger is there is in such hanging method when constructing, because steel girder member bar adopts polybag parcel, when lifting, steel girder member bar is inevitably subject to the extruding of wire rope, polybag is caused to break, still can cause greasy dirt to steel girder member bar, after-treatment must be carried out to steel girder member bar; Next affects larger by manpower factor, it is firm that the front manpower of lifting can not ensure that parcel bag and steel girder member bar bundle by wire rope, in lifting process, easily cause steel cable sliding even to come off, make steel girder member bar centre-of gravity shift, cause steel girder member bar to collide loop wheel machine, even collide mounted steel girder member bar, cause construction accident, and need support staff more, generally need 4 ~ 6 people to carry out parcel steel girder member bar, cost is high, and efficiency is low.Current this area does not still have good construction technology available.
Summary of the invention
The object of the invention is to overcome the defect of lifting existing for steel girder member bar at present, and a kind of using method of fast hoisting steel girder member bar is provided.
The technical scheme of special hanger of the present invention is:
At base slab both sides difference fixation side riser, between cant board Zhong Gu Ding Transverse clamping plate Transverse clamping plate both sides base slab on have two bolts hole, device set bolt in bolt hole, two alignment pins are fixed below flat-floored, the spacing of two bolts hole and two alignment pins has lifting eye with the top of the bolt hole spacing completely the same ， Transverse clamping plate on steel girder member bar to be hung respectively;
The using method of special hanger of the present invention is:
A. be connected with the lifting eye of special hanger with the U-shaped ring on lifting machine wire rope, respectively two special hangers worked the two ends winching to steel girder member bar, alignment pin is aimed at respectively in the bolt hole of insertion steel girder member bar end;
B. in bolt hole set bolt being penetrated respectively special hanger and steel girder member bar and fastening nut, make special hanger being fixed on steel girder member bar tightly, and ensure that the base slab of special hanger and the surface of steel girder member bar are close to;
C. be connected with the lifting eye of two special hangers with the U-shaped ring on lifting machine two wire rope, ensure that the length of two wire rope is identical, the steel girder member bar sling keeps level, and steel girder member bar rises and winches to design and installation position by lifting machine stably simultaneously;
D. adjustment determines that steel girder member bar installation site is fixed after accurate, then lay down set bolt, special hanger lifting is departed from steel girder member bar, and fast hoisting steel girder member bar has been constructed, repeat above flow process, start the lifting of next steel girder member bar.
The present invention adopts special hanger to lift by crane steel girder member bar, can not be there is loosening landing in lifting process, and can not cause secondary pollution to rod member, and the lifting time is short, reliability is strong, simple to operate, fast, compounding practice personnel are few in construction, effectively shorten the construction period, reduce construction cost, and be suitable for the lifting of different size steel girder member bar, can widely use on the hoisting engineering of similar steel beam column.By the physical dimension of change suspender, steel plate thickness, lifting eye size and spacing, the requirement lifting different size steel girder member bar can also be realized.
