Abstract

The invention discloses a lifting construction process of modular steel structural components. The lifting construction process comprises the following steps: steel structural components are spliced to multiple piece type frames; the piece type frames are lifted to a frame unit assembly position after being assembled; left and right two truss type frames are lifted and positioned on an assembly platform for alignment and adjustment, and connecting components between the two truss type frames are assembled to form complete frame units; and the fixed welding of all frame units is finished. The lifting construction process reasonably divides the whole steel structural frame into multiple modules, then assembles the steel structural components to multiple modules, and finally performs the lifting installation and the final assembly according to the module segmentation sequence, so that the aerial operation and assembly lifting difficulty is reduced; and multiple modules can be synchronously assembled on the ground, so that the assembly working plane is increased, the whole construction progress is fastened, and the construction period is shortened.

Description

A kind of hoisting construction process of module-type steel structure component
Technical field
The invention belongs to steel building technical field, specifically a kind of hoisting construction process of module-type steel structure component.
Background technology
Structural steelwork is made as main structure with steel, is one of main building construction types.The feature of steel is that intensity is high, from heavy and light, integral rigidity is good, deformability is strong, thus for building large span and superelevation, extra-duty building is suitable especially; Material homogeneity and isotropism good, plasticity, good toughness, can have moderate finite deformation, and can bear dynamic loading well, construction period is short, and machining accuracy is high, and its industrialization degree is high, can carry out the high Virtual production of mechanization degree.
Along with the moulding of steel work and form of structure become increasingly complex, weight is well beyond the maximum bearing value of tower crane, high to construction requirement, and the integral hoisting of steel structure member has been difficult to accomplish.
Summary of the invention
The object of the invention is to the defect overcoming prior art existence, a kind of hoisting construction process of module-type steel structure component is provided.
Object of the present invention can be achieved through the following technical solutions:
A hoisting construction process for module-type steel structure component, is characterized in that, comprises the following steps:
(1) steel structure member is assembled into several chip frameworks, first two root posts is hung onto on assembly platform, adjustment bearing, side direction and end face pattern centering, levelling, then assembling connects crossbeam, diagonal brace, carries out the fastening of connector or welds; Framework corresponding for steel structure module is arranged on same group of assembly platform and assembles;
(2) after chip frame assembled, handling is to frame unit assembling position, and suspension centre selects the Nodes of end floor beam and column on chip framework;
(3) left and right two Pin chip framework is hung be positioned on assembly platform, after centering and adjustment, assemble the connecting elements between two Pin chip frameworks, form complete frame unit;
(4) rise on operation platform by frame unit, make frame unit and mounted steel work contraposition, adjustment corrects verticality, by frame unit and mounted welding for steel structure, repeat, until lifted all frame units, complete being welded and fixed of all frame units.
As preferred further, under assembly platform of the present invention, adjustable seats is installed, described adjustable seats is adjustable backing plate or H profile steel moulding bed, plays supporting steel structure module, adjusts, controls the verticality of assembling and remain in assembly platform same level.
Beneficial effect of the present invention: bed rearrangement steel structure frame is rationally divided into several modules by the present invention, then steel structure member is assembled into a lot of modules, finally carry out lifting respectively to the order of module segmentation to install and general assembly, decrease the difficulty of work high above the ground and assembling lifting; Multiple module can simultaneously be assembled in face, expands assembling operation face, accelerates the progress of integral construction and shortens the construction period.
Detailed description of the invention
Embodiment 1
A hoisting construction process for module-type steel structure component, comprises the following steps:
1, accurately process steel work component used, the scene of being sent to is carried out checking, checks, checks, is checked and accepted.Check the quantity and material object of checking component.Check and see whether the workmanship of component meets specification.
2, steel structure member is assembled into several chip frameworks, first two root posts is hung onto on assembly platform, adjustment bearing, side direction and end face pattern centering, levelling, then assembling connects crossbeam, diagonal brace, carries out the fastening of connector or welds; Framework corresponding for steel structure module is arranged on same group of assembly platform and assembles.Be provided with adjustable seats under assembly platform, described adjustable seats is adjustable backing plate or H profile steel moulding bed, plays supporting steel structure module, adjusts, controls the verticality of vertical assembled and remain in vertical assembled platform same level.
3, after chip frame assembled, handling is to frame unit assembling position, and suspension centre selects the Nodes of end floor beam and column on chip framework.The present invention selects lifting wire rope to lift.
Lifting wire rope is selected and is calculated by formula [Fg]=aFg/K
Wherein, K---safety factor, makes binding hoist cable span 8-10, gets 10
A---rupture pull force conversion coefficient steel cord structure is 0.8
[Fg]---allow pulling force 2 liftings to get 12.5/2=6.25t
Wire rope conscientiously will check there is fracture of wire phenomenon before using.
4, left and right two Pin chip framework is hung be positioned on assembly platform, after centering and adjustment, assemble the connecting elements between two Pin chip frameworks, form complete frame unit.
5, rise on operation platform by frame unit, make frame unit and mounted steel work contraposition, adjustment corrects verticality, by frame unit and mounted welding for steel structure, repeat, until lifted all frame units, complete being welded and fixed of all frame units.
Adopt angle steel to be fixed by stone bolt as a whole, by fixed support and base plate steel bar binding, add rigid support in fixed support surrounding, then baseplate reinforcing bar is welded as a whole.
