Abstract
The utility model discloses a special lifting apparatus for quickly hoisting a steel trussed beam rod piece, and belongs to the field of road bridge construction. The technical scheme of the special lifting apparatus is as follows: lateral vertical plates are respectively fixed on two sides of a flat base plate; a transverse clamping plate is fixed in the middle of the lateral vertical plates; bolt holes are respectively formed in the flat base plate on the two sides of the transverse clamping plate; locating pins are fixed at the lower part of the flat base plate; the distance between the locating holes and the locating pins are respectively identical with those of the bolt holes in the steel trussed beam rod piece; a lifting hole is formed in the upper part of the transverse clamping plate. With the adoption of the special lifting apparatus provided by the utility model to hoist the steel trussed beam rod piece, in the hoisting process, the steel trussed beam rod piece is not released to slip, so that the rod piece cannot be polluted for the second time. The special lifting apparatus is short in hoisting time, strong in reliability, simple in operation, and quick in construction, requires a few of cooperating operators, effectively shortens the construction period, reduces the construction cost, can be applied to hoisting the steel trussed beam rod pieces with different specifications, and can be widely applied to hoisting engineering similar to the steel member.
Description
Technical field
The utility model relates to a kind of aid of steel member construction, and specifically a kind of special hanger 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 are crossed over Existing Railway Bridges or existing highway bridge gets more and more.Owing to being subject to works and the control of circuit overall height under line, 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, just become a key link of steel truss girder construction.The construction method of steel girder member bar lifting is at present to adopt wire rope binding lifting, in the time of 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 bundle at suspension centre place with wire rope, adopt U-shaped ring to connect, then complete and lift by crane installation with lifting machine.In the time of construction, there is more hidden danger in such hanging method, because steel girder member bar adopts polybag parcel, in the time of 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 by firm to 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, the even mounted steel girder member bar of collision, 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 aid available at present.
Utility model content
The purpose of this utility model is to overcome the existing defect of current lifting steel girder member bar, and a kind of special hanger that can lift effectively rapidly steel girder member bar is provided.
The utility model is achieved through the following technical solutions
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;
Adopt the utility model 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 shorten the construction period, reduce 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.
Accompanying drawing explanation
Accompanying drawing 1 is the main TV structure schematic diagram of special hanger of the present invention;
Accompanying drawing 2 is left TV structure schematic diagrames of special hanger of the present invention;
Accompanying drawing 3 is plan structure schematic diagrames of special hanger of the present invention.
Description of reference numerals is as follows:
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
At base slab (1) both sides difference fixation side risers (2), Gu is Dinged on the base slab of Transverse clamping plate (3) Transverse clamping plate (3) both sides and is had two bolts hole (4) in the middle of cant board (2), device set bolt (5) in bolt hole (4), below base slab (1), fix two alignment pins (6), the spacing of two bolts hole (4) and two alignment pins (6) respectively with steel girder member bar to be hung (8) on the top of bolt hole spacing ， Transverse in full accord clamping plate (3) have lifting eye (7);
Steel girder member bar (8) weight is less than 20 tons, and the steel plate thickness of special hanger is selected 3cm, and steel girder member bar (8) weight is between 20 tons to 30 tons, and the steel plate thickness of special hanger is selected 5cm.
When use, be connected with the lifting eye of special hanger with the U-shaped ring of lifting machine wire rope, 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; 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; Be connected with the lifting eye of two special hangers with the U-shaped ring of two wire rope of lifting machine, guarantee that the length of two wire rope is identical simultaneously, the steel girder member bar maintenance level of slinging, lifting machine plays steel girder member bar and winches to design and installation position stably; 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.
