Description
Technical field
The present invention relates to building trade integral installation technology field, particularly relate to a kind of for sail type
The thrusting slip erecting device of box girder steel and method.
Background technology
Along with the increase day by day of city large-scale tall buildings, and Building technology is growing,
Layer Steel Structure is installed and is increasingly paid attention to by relevant insider.
As a example by practice of construction engineering, center, core perseverance strand B bid section project is by 4 33 floor heights
Layer house composition, all there are the steel construction moulding of a sail type, single roof steel knot in roof, Mei Dong building
Structure steel using amount about 650 tons, 4 building Weight of steels are 2600 tons.Main member is respectively by 5 Pin casees
Section steel beam and linking beam and composite roof truss form.Steel beam with box shape flange plate and web are 38 millis
Rice steel plate.Wherein, the cross section of ZGJ1 girder steel is 1.5 meters × 0.6 meter, box beam 1210kg/m,
The cross section of ZGJ2 girder steel is 1.5 meters × 0.8 meter, box beam 1330kg/m.Single Pin girder steel is maximum
Weight about 108 tons, maximum span is 52 meters.Two end bearings are respectively provided at building roof north and south
800 thick floor faces of both sides.Top setting height(from bottom) is 133 meters, and steelframe relative altitude is about
20 meters.
According to traditional building construction technology, layer Steel Structure is installed and will be used high-altitude assembly
Technical scheme.This technical scheme drawback is a lot: one is that the welding node of assembly is many, weldering
Connect quantities big；Two is component high-altitude low precision in place, and installation quality is difficult to ensure that；Three is to take
The quantities building full hall scaffold is big, the most unreasonable with in project benefit in Financial cost,
And affect the construction of other operations of roof to a great extent.
Summary of the invention
It is an object of the invention to provide a kind of thrusting slip for sail molding box formula girder steel to install
Device and method, the high-altitude loose mail used to solve layer Steel Structure of the prior art to install is spelled
The welding node that dress scheme exists is many, quantities is big, high-altitude low precision in place, deficiency in economic performance
Deng problem.
To achieve these goals, the present invention is by the following technical solutions:
A kind of thrusting slip erecting device for sail molding box formula girder steel that the present invention provides, including
Support, the first slideway and the second slideway and pusher；Described first slideway and described second slideway
It is horizontally disposed with and is parallel to each other；Described support is arranged on described first slideway and described second slideway
Between, for supporting girder steel to be installed；Described pusher is along described first slideway and described
Two installation of slide tracks, for jack-in erection steel on described first slideway and described second slideway
Beam.
Further, the 3rd slideway is also included；Described 3rd slideway shelf sets on the bracket, and
All it be arranged in parallel with described first slideway and described second slideway.The technique effect of this technical scheme
It is: the 3rd installation of slide track is on support, the most parallel with the first slideway and the second slideway, and
3rd slideway in the middle part of the support steel beam, with the first slideway and the second slideway with the use of, it is possible to
Improve stability during steel roof joist sliding.
Further, platform for lining is also included；Described support, described first slideway and described second
Slideway is all fixedly mounted on the upper surface of described platform for lining.The technique effect of this technical scheme exists
In: platform for lining is used for fixing the first slideway, the second slideway and support, it is to avoid make ground
Become to destroy.Platform for lining according to being actually needed production technique or can have certain inclination simultaneously
The platform of angle, to meet being actually needed of building body.
Further, built-in fitting is also included；Described built-in fitting is arranged on described platform for lining, uses
In fixing described first slideway and described second slideway.Having the technical effect that of this technical scheme
Owing to the first slideway and the second slideway are subjected to the weight of girder steel, and bear the horizontal of girder steel
Frictional force, arranges built-in fitting on platform for lining, it is possible to plays and fixes the first slideway and the second cunning
The effect in road.
Preferably, described pusher is hydraulic top thruster.Having the technical effect that of this technical scheme
Fluid pressure type pusher simple in construction but stable drive, light weight volume are little and bearing capacity big, special
It is not applicable to the torque transmitting under low speed.Further, hydraulic drive easily realize overload protection and
Reciprocating.
Further, described first slideway, described second slideway and described 3rd slideway are by H
Structural section is made.This technical scheme have the technical effect that H profile steel is the building of a kind of economy
Use steel.H profile steel cross sectional shape economical rationality, mechanical property is good, and during rolling, on cross section, each point prolongs
Stretch more uniform, internal stress is little.Compare with common I-steel, have modulus of section big, lightweight,
The advantage saving metal, can make building structure alleviate 30-40%；Again because of external side parallel in its lower limb,
Lower limb end is right angle, and assembling combination becomes component, can save welding, riveting work amount reaches 25%.Often
For requiring that bearing capacity is big, the heavy construction that cross-sectional stability is good, and bridge, boats and ships,
Handling machinery, equipment Foundations, support, foundation pile etc..The first cunning that H profile steel material is made
Road, the second slideway and the 3rd slideway preferably bear support force and the frictional force of girder steel.
Present invention also offers a kind of thrusting slip installation method for sail molding box formula girder steel, bag
Include following steps: be lifted on respectively at the two ends of girder steel on the first slideway and the second slideway, utilize
Support supports girder steel, by pusher by girder steel thrusting slip to presetting position, to many
Same operation implemented by individual girder steel, and the installation completing layer Steel Structure is fixed.
Further, support arranges the 3rd slideway, utilize central hydraulic pump source system the most right
Girder steel on first slideway, the second slideway and the 3rd slideway carries out thrusting slip.This technical scheme
Have the technical effect that the 3rd slideway be set, pusher can be set up on the 3rd slideway simultaneously,
Improve girder steel stability in translation.
Further, by multiple girder steel thrusting slips to set position after, adjacent girder steel it
Between weld coupling beam and truss.This technical scheme have the technical effect that girder steel is as roof structure
Skeleton, between multiple girder steels, weld coupling beam and truss, it is possible to by the bone of whole roof structure
Frame is fixed, and roof structure plays the effect of shaping structures and support.
Further, after welding coupling beam and truss between adjacent girder steel, multiple girder steels are carried out
Paint is repaired.This technical scheme have the technical effect that girder steel during thrusting slip, with
And during tower crane, scratch unavoidably and cut occurs, between girder steel, weld coupling beam and purlin
After frame, re-use paint and repair, it is possible to reduce cut, it is to avoid get rusty, extend girder steel
Service life.
The invention has the beneficial effects as follows: for sail molding box formula girder steel thrusting slip erecting device and
Method, supports girder steel first with the first slideway, support and the second slideway, then passes through pushing tow
Multiple girder steel thrusting slips to predetermined position, are formed layer Steel Structure skeleton, this installation by device
Apparatus and method, it is to avoid a large amount of scaffolds build engineering, decrease unnecessary welding job
Amount, improves the high-altitude precision in place of component and the installation effect of sail molding box formula girder steel roof structure
Rate.
