Abstract
The invention discloses a lifting device special for rapidly lifting a steel truss girder rod piece and a using method. Side vertical plates are fixedly arranged on the two sides of a flat bottom plate respectively. A transverse clamping plate is fixedly arranged between the side vertical plates. Bolt holes are formed in the flat bottom plate. Positioning pins are fixedly arranged below the flat bottom plate. Intervals between the bolt holes and the positioning pins are completely consistent with those between bolt holes in the steel truss girder rod piece respectively. A lifting hole is formed in the upper part of the transverse clamping plate. When the lifting device is used, two special lifting devices are lifted to the two ends of the steel truss girder rod piece through a crane, fixing bolts are inserted into the bolt holes of the special lifting devices and the steel truss girder rod piece for fixation after the lifting devices are positioned respectively, the steel truss girder rod piece is lifted to a designed mounting position through the crane, and the fixing bolts are disassembled. According to the special lifting device, loosening and sliding in a lifting process can be avoided, secondary pollution to the rod piece can be avoided, the special lifting device is short in lifting time, high in reliability, easy to operate, high in construction speed, short in construction period and low in cost, and can be used for lifting steel truss girder rod pieces with different specifications, and a few matched operators are required.
Description
Technical field
The present invention relates to a kind of special hanger and using method of steel member, specifically a kind of special hanger of fast hoisting steel girder member bar and using method, belong to road and bridge construction field.
Background technology
Along with developing rapidly of road traffic, the phenomenon that overhead railway and sky way are crossed over Existing Railway Bridges or existing highway bridge gets more and more.Due to the control that is subject to works and circuit overall height under line 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 models, and lightweight tens tons of rod member is heavy 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 job practices of steel girder member bar lifting is at present to adopt wire rope binding lifting, when lifting steel girder member bar, in advance at steel girder member bar suspension centre place parcel polybag, with this prevent steel girder member bar in when lifting by wire rope greasy dirt, then with wire rope, at suspension centre place, bundle, adopt U-shaped ring to connect, then complete lifting installation with lifting machine.When construction, there is more hidden danger in such hanging method, because steel girder member bar adopts polybag parcel, when lifting, steel girder member bar inevitably can be subject to the extruding of wire rope, cause polybag to break, still can cause greasy dirt to steel girder member bar, must carry out after-treatment to steel girder member bar; Next is that affected by manpower factor larger, before lifting, manpower can not guarantee that wire rope is firm by parcel bag and steel girder member bar binding, in lifting process, easily cause that steel cable sliding even comes off, make steel girder member bar centre-of gravity shift, cause steel girder member bar collision loop wheel machine, even collide mounted steel girder member bar, cause construction accident, and need support staff more, generally need 4 ~ 6 people to wrap up steel girder member bar, cost is high, and efficiency is low.This area does not still have good construction technology available at present.
Summary of the invention
The object of the invention is to overcome the existing defect of current lifting steel girder member bar, and a kind of special hanger and using method of fast hoisting steel girder member bar are provided.
The technical scheme of special hanger of the present invention is:
At base slab both sides difference fixation side riser, Gu is Dinged on the base slab of Transverse clamping plate Transverse clamping plate both sides and is had two bolts hole in the middle of cant board, device set bolt in bolt hole, below flat-floored, fix two alignment pins, the spacing of two bolts hole and two alignment pins respectively with steel girder member bar to be hung on the top of bolt hole spacing ， Transverse in full accord clamping plate have lifting eye;
The using method of special hanger of the present invention is:
A. with the U-shaped ring on lifting machine wire rope, be connected with the lifting eye of special hanger, respectively two special hangers played to the two ends that winch to steel girder member bar, alignment pin is aimed at respectively in the bolt hole that inserts steel girder member bar end;
B. set bolt is penetrated respectively in the bolt hole of special hanger and steel girder member bar and fastening nut, make special hanger being fixed on steel girder member bar tightly, and guarantee that the base slab of special hanger and the surface of steel girder member bar be close to;
C. with the U-shaped ring on two wire rope of lifting machine, be connected with the lifting eye of two special hangers, guarantee that the length of two wire rope is identical, the steel girder member bar of slinging keeps level simultaneously, and lifting machine plays steel girder member bar and winches to design and installation position stably;
D. adjust and determine that steel girder member bar installation site is fixed after accurate, then lay down set bolt, special hanger lifting is departed to steel girder member bar, 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 lifting steel girder member bar, can there is not 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 shortened the construction period, reduced construction cost, and be suitable for the lifting of different size steel girder member bar, can on the hoisting engineering of the steely member of class, be widely used.Can also, by changing physical dimension, steel plate thickness, lifting eye size and the spacing of suspender, realize the requirement of lifting different size steel girder member bar.
