Description
Technical field
The present invention relates to Steel Structure Installation field, specifically a kind of large-scale steel structure column hanging method.
Background technology
The intensity that steel construction possesses is high, the characteristic such as plasticity and good toughness, good ductility, determines itself possess outstanding
Anti-seismic performance, also cause steel construction be widely used at aspects such as skyscraper, large-span space structure and bridges.
Steel construction is main to fix assembled by components such as column, crossbeams, typically sharp for steel structural upright column installation
Column is lifted to precalculated position with loop wheel machine, because steel construction central post is often higher, particularly large-scale steel structure stem height
More than ten rice are can reach, after the completion of lifting, how safely and efficiently crane hook and column is separated into lifting operation
Important step, is the key factor for influenceing lifting operation duration.Currently, crane hook is separated with column mainly has three kinds of modes：
, be hung to operating personnel at column lifting by another loop wheel machine by the first, using artificial mode by crane hook with
Column is separated, or operating personnel is climbed to column lifting, suspension hook is separated with column, and both approaches are time-consuming more long, effect
Rate is relatively low, and operating personnel's operating risk is higher, cannot ensure safely；
Second, a soft circle of steel wire being relatively large in diameter is set with the lifting of column, and fastened in the way of slip-knot using rope
The soft circle middle part of steel wire, makes steel wire soft circle gathering be tightly placed on column cylinder, while rope reserves one end to Ground Operation people
Member, after the completion of column lifting, operating personnel makes the slip-knot of rope be come off from the soft circle of steel wire, the soft circle of steel wire by pulling rope
Diameter becomes big, falls to ground from column automatically；This mode is although simple to operate, and cost is relatively low, but for complex-shaped
Column（Such as column middle part has prefabricated strutbeam）, cause the soft circle of steel wire to fall to ground；
The third, in the prefabricated hanger in the lifting point of column, is connected, this unhook between crane hook and hanger by detacher
Device makes the bearing pin of detacher depart from hanger often by pneumatic or electronic control mode, realizes suspension hook with hanger point
From although this method can preferably improve lifting efficiency, pneumatic and electronic detacher cost of manufacture is higher and need to determine
Phase safeguards, simultaneously because lifting site environment is typically more complicated, this kind of pneumatic and electronic detacher is highly prone to damage, and
And detacher is after being damaged, if do not found in time, after the completion of lifting, still need to by manually by detacher and hanger
Separate, operating difficulties, it is dangerous also higher.
The content of the invention
In order to solve problem present in existing hoisting technology, it is good, reliable that the present invention provides a kind of simple to operate, adaptability
Property strong large-scale steel structure column hanging method, to improve the efficiency of column lifting.
Concrete scheme of the invention is：Column bases are poured into a mould first, and several are fixed on the end face of pedestal upper end and is stood
The bolt of column bottom mounting hole matching, then installs column according to the following steps：
The first step：Hanger is set up on the top of column；
Second step：Horizontal load-bearing block is installed on each bolt, and use level instrument ensures the Horizontal load-bearing on all bolts
Block upper surface is on same horizontal plane；
3rd step：Make the detacher with hanger and lifting appliance Matching installation, the detacher have connection column hanger with
The suspending assembly of lifting appliance, pin-and-hole is provided with the suspending assembly position corresponding with hanger lifting hole(eyelet), and pin-and-hole is built with through hanging
The bearing pin of ear lifting hole(eyelet), the unhook component that bearing pin can be made to depart from hanger lifting hole(eyelet) is equipped with one end of bearing pin；The unhook group
Part includes " ┌ " the type fixed arm being fixed on the draw bar of load-bearing pin connection and one end on suspending assembly, is covered on the draw bar
Back-moving spring equipped with pushing tow bearing pin, Matching installation has one end to be fixed on the spacing collar on suspending assembly on back-moving spring,
The bending part of " ┌ " the type fixed arm is equipped with horizontally disposed fixed pulley contour with draw bar, in the level of " ┌ " type fixed arm
Section and vertical section be also equipped with limit pull rope swing fixture block, with prevent pull rope depart from pulley cause it is stuck cause bearing pin without
The phenomenon that method departs from hanger occurs；
4th step：It is solid pull rope on draw bar in detacher, pull rope is along " ┌ " type fixed arm is by fixture block and determines
Pulley fastens the bottom of upper pillar stand, to prevent the swing of the pull rope in hoisting process；
5th step：Column is lifted to pedestal, the mounting hole of column bottom is matched and is sleeved on the corresponding bolt of base end face
On, and fix locking using nut；
6th step：The end that pull rope is located at column bottom is pulled, and under the guiding of fixed pulley, draw bar is moved in the horizontal direction
It is dynamic, drive bearing pin to depart from hanger, realize the natural separation of detacher and column.
One week of column bottom of the present invention is provided with flanging, and several mounting holes are symmetrically and evenly distributed in column bottom
On two relative flangings.
Suspending assembly of the present invention has the two clamping plates for being clamped on hanger both sides, the top between two clamping plates
It is welded with the boatswain chair being connected with crane hook.
One end of bearing pin of the present invention has baffle plate, and draw bar and back-moving spring are connected by baffle plate with bearing pin
Connect.
" ┌ " type fixed arm of the present invention is the inverted U-shaped structure that bottom is opening, and the pulley is arranged on " ┌ " type
Fixed arm bending part, it is also opening that " ┌ " type fixed arm is located at spacing collar and the top position of horizontally tracting bar, in order to incite somebody to action
It is solid fraction state that pull rope system is also convenient for observation simultaneously admittedly in link.
Compared to traditional steel structural upright column hanging method, the advantage that the present invention possesses is：
1st, the present invention replaces traditional pneumatic or electronic side on the premise of lifting efficiency is ensured by the way of artificial pulling
Formula makes bearing pin depart from hanger, greatly reduces the manufacturing cost and later maintenance cost of detacher；
2nd, simple structure of the present invention, simple operation, have effectively ensured lifting efficiency, simultaneously because being not directed between each part
Easily worn part is pneumatically or electrically waited, fault rate is low, good reliability, preserve convenient, be adaptable to the steel structural upright column of all kinds of environment
Lifting operation；
3rd, the position being located between draw bar and pulley in " ┌ " type fixed arm in the present invention sets stopper slot, remains traction
Rope is always positioned in the slideway of pulley during pulling, effectively prevent stuck phenomenon caused by pull rope departs from pulley,
Lifting efficiency is ensured.
