The technical solution of any obvious substitutions and modifications out.
As shown in figures 1-4, a kind of large-span steel girder mounting slip and promotion coupling apparatus, including slide device and promotion
Device.Slide device includes setting in the transfer car(buggy) (3) of girder steel (1) bottom and is stuck in the gib bars of girder steel (1) two sides
(4), prevent girder steel (1) from rolling in slipping.Gib bar (4) can reuse, and reduce the waste of resource.Temporarily
Branch guard bar (4) is arranged at girder steel (1) end 3m.Gib bar (4) includes brace (41) and cross bar (42).Brace (41)
Top is provided with horizontal bayonet (43), and brace (41) is stuck on the top flange plate of girder steel (1) by horizontal bayonet (43).Cross bar
(42) one end is rigidly attached to the middle part of brace (41), and the other end of cross bar (42) is in contact with the web of girder steel (1).Brace
(41) it is no more than 5 centimetres with the height on ground.
Lifting device is arranged on the upper layer floor above girder steel, including being symmetrical arranged hoisting bracket on the upper floor
(5) and the bottle gouard moved by hands (2) on hoisting bracket (5) is hung over.When lifting, the upper end of bottle gouard moved by hands (2) hangs over hoisting bracket (5)
On, lower end is hung over by hanging ring on the card ear at girder steel (1) both ends.Hoisting bracket (5) includes pedestal (51), is rigidly attached to pedestal
(51) perpendicular support (52) on, is rigidly attached to perpendicular support (52) at the horizontal cantilever (53) for being rigidly attached to perpendicular support (52) top inner side
The main brace (54) of apical lateral and the reinforcement diagonal brace (55) being rigidly attached between perpendicular support (52) and horizontal cantilever (53) and
The reinforcement stull (56) being rigidly attached between perpendicular support (52) and main brace (54).It is to be embedded in upper floor that pedestal (51), which is one,
The longitudinal fashioned iron arranged in plate and along upper floor edges of boards along direction.Pedestal (51), perpendicular support (52), horizontal cantilever (53), master are oblique
Support (54) reinforces diagonal brace (55) and reinforces the section steel manufacture that stull (56) are all made of model HW200*200*8*12.It is laterally outstanding
The length of arm (53) is the 1/3~1/2 of the height of perpendicular support (52).Main brace (54) and the angle on ground are 60~70 °, to guarantee
When hoisting steel beam, the stress of hoisting bracket (5) is more reasonable.
By taking specific a certain project under construction as an example, certain project is a 12 floor business building, and occupied area is 3.01 ten thousand m2, build
Build 21.01 ten thousand m of area2, building general height 63.6m, structure type is steel reinforced concrete frame structure, and whole architectural image is new
Grain husk, it is uneven.Design has 12 large-span steel girders between ten layer 24 of project East axis~28 axis, and girder steel section is H1200*
300*28*40, linear meter(lin.m.) weight be 0.42t/m, depth of section 1.2m, up to 25m, most it is short be 21.6m, most heavy 11.6t, most gently
9.2 tons, always weigh about 163 tons.This 12 large-span steel girders are the construction Difficulties of the engineering.
The process of the installation of above-mentioned girder steel are as follows:
1. using midas8.0 finite element analysis software calculate the downwarp under the self weight of girder steel (1), construction loads effect with
And the stress condition at girder steel (1) both ends, the deformation values of hoisting bracket (5) each node are checked, determine the reserved clipping room of girder steel (1)
Gap and pre- springing quantum.Girder steel is self-possessed 1.2DL, and load cases combination takes 1.4D when analysis, selects the type of model HW200*200*8*12
The hoisting bracket of steel production meets construction stress requirement in conjunction with stress condition.
2. carrying out segmented assembly using pre- arch camber to girder steel (1) on the ground according to the length and weight of girder steel (1).Knot
Live reality and tower crane performance are closed, equitable subsection is carried out to girder steel, every girder steel is divided into 4 ends, plays tower crane to the maximum extent
Effect reduces girder steel and transports number.If first segment is 7.9m, 4.6 tons are weighed；Second segment 6.5m weighs 3.7 tons；Third section 6m, weight
3.5 ton；4th section of 5.1m, weighs 3 tons.Pre- arch camber measure is used when assembled.Girder steel (1) avoids high-altitude pair in nine laminate face assembly
It connects, guarantees construction precision, reduce error.Hoist ability due to tower crane in girder steel position to be assembled is only 2.3 tons, and most heavy
Girder steel weight 4821.54kg then uses tower crane by girder steel so not being available tower crane is directly transported to position to be assembled for girder steel
Segmentation is transported at nine floor face girder steel stackings, is then transported to position to be assembled using fork truck and is completed assembly.
3. the girder steel (1) that assembly is completed is hung to transfer car(buggy) (3) with tower crane, it is arranged at girder steel (1) both ends that assembly is completed
Gib bar (4), girder steel (1) slide onto position to be installed.At girder steel (1) end 3m position setting it is reusable
Gib bar (4), height of the bottom end of gib bar (4) apart from ground be no more than 5cm, to prevent girder steel (1) in cunning
It is rolled during moving.When encountering concrete column blocking when sliding, adjustment angle appropriate enables girder steel to pass through.
4. setting up hoisting bracket (5) on the upper layer floor above girder steel (1), 10 tons are hung on hoisting bracket (5)
The lower end of bottle gouard moved by hands (2), bottle gouard moved by hands (2) is hung over by snap ring on the lifting lug of girder steel (1), and the upper end of bottle gouard moved by hands (2) is hung
It on hoisting bracket (5), is promoted using bottle gouard moved by hands (2), guarantees that girder steel (1) is horizontal in lifting process.If when lifting
The position for having concrete column is encountered, hoisting bracket (5) is unable to satisfy requirement, needs to be modified slightly hoisting bracket (5), will lift
The pedestal (51) of bracket (5) replaces with anchor ear, and anchor ear is encircled on concrete column.
Girder steel (1) is promoted to predeterminated position, finally carries out the installation of girder steel.
Above embodiment is only that preferred embodiments of the present invention are described, not to the utility model
Range be defined, under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this is practical
The various changes and improvements that novel technical solution is made should all fall into the protection scope that the utility model claims book determines
It is interior.
