Description
Technical field
The present invention relates to the installation Technology in a kind of building construction process, more particularly to a kind of high large-span truss are whole
Body translates construction method for hanging.
Background technology
At present, high large-span truss lifting operation typically makes processing using in structure factory, and burst is transported to job site
Install in place pre- lifting region, the installation position that structures are finally lifted to using the crane of relevant parameter.The construction method is constructed
There is no problem for the not high steel structure installation of general span low height, but construction large span, the truss construction of height superelevation have three
Big defect：First, fabricating yard is needed to carry out carry out rationalization partition orderly in a organized way, each preassembling component is identified, to hanging
The tissue difficulty for pretending industry is larger.Second, each pre-splicing connection member weld job when top is installed requires high, substantial amounts of to connect
The quality of head is difficult to ensure that, larger in high aerial inspection from sample difficulty simultaneously for first-order weld, if in the weldering of upper detection part
Seam is unqualified to be had weld defect and is difficult to do over again, influence steel truss integral rigidity and stability.3rd, because of most splicing work
Work be in hoisting process complete, its lifting operation it is long in time limit, while security risk increase.
The content of the invention
To solve the above problems, the present invention provides a kind of high large-span truss integral translation construction method for hanging, two are utilized
Platform is identical or large-scale cranes of different parameters, has hung two ends Heave Here, two cranes are distributed in truss two ends, before pre-
The track route proposed is walked unhurriedly lifting, to be lifted to arrive certain altitude, and two cranes assist synchronous slowly to move to structures peace
The lower section at dress position, then integral lifting are in place.
A kind of high large-span truss integral translation construction method for hanging of the present invention, Specific construction step is as follows：
(1) construction technology prepares：If two crane performance parameters are different, that every crane need to undertake should be calculated in advance
Lift heavy amount, and after truss lifting two ends difference of height and angle.
(2) crane track route figure is lifted according to the high large-span truss integral translation of Steel Structural Design drawing compilation；
(3) truss fabrication and transport：Make and weld in the assembly of structure factory, check welding quality and carry out flaw detection experiment,
Ensure that weldquality is qualified；Derusting anti-corrosive construction is carried out to component；The high large-span truss for making qualified is transported to job site
Lifting operation region；
(4) crane walking roadshow is carried out before formal lifting, it is ensured that crane smooth running in hoisting process；
(5) leveling is carried out to pre-installation truss structure base and pre-treatment is installed；
(6) steel wire rope of two crane lifting truss is hung on to the Heave Here of the steel truss of pre- lifting；
(7) by the crane track route figure woven, lifted slowly after truss lifting certain altitude, then by two cranes
Travel to the lower section of structures truss installa-tion；
(8) truss lifting is in place, and truss integral lifting exceeds the top of mounting seat, and adjustment is installed on base；
(9) truss and base are consolidated and are connected.
Further, the piece of smooth land, the piece of smooth land after hardening in crane travel region are hardened according to step (2) crane track route figure
Except compacting factor experiment need to be done；While carrying out post training to crane operator and telling somebody what one's real intentions are in detail.
Further, in (7) two crane walking processes of step, two cranes remain a constant speed forward, steel wire rope part side
Notice that crane collaboration moves pendulum into swing, it is ensured that steel wire rope and truss integral translation.
Further, when step (8) lifting is in place, if two crane performance parameters are different, need the big one end of load-bearing first
In place, then the other end can be slowly in place.
Compared with prior art, the construction method advantage of the invention is：
1) construction method of the invention greatly reduce lifting it is in place after weld job workload, it is ensured that overall truss it is whole
Body stability and truss rigidity；
2) construction method of the invention is easy to operate, and speed of application is fast, can effectively improve truss installa-tion duty cycle.
Brief description of the drawings
Fig. 1 is a kind of process chart of high large-span truss integral translation construction method for hanging of the present invention.
Embodiment
Invention is further described with reference to Figure of description.
As shown in Fig. 1 process chart, a kind of high large-span truss integral translation lifting of the invention
Construction method, Specific construction step is as follows：
(1) construction technology prepares：If two crane performance parameters are different, that every crane need to undertake should be calculated in advance
Lift heavy amount, and after truss lifting two ends difference of height and angle.
(2) crane track route figure is lifted according to the high large-span truss integral translation of Steel Structural Design drawing compilation；
(3) truss fabrication and transport：Make and weld in the assembly of structure factory, check welding quality and carry out flaw detection experiment,
Ensure that weldquality is qualified；Derusting anti-corrosive construction is carried out to component；The high large-span truss for making qualified is transported to job site
Lifting operation region；
(4) crane walking roadshow is carried out before formal lifting, it is ensured that crane smooth running in hoisting process；
(5) leveling is carried out to pre-installation truss structure base and pre-treatment is installed；
(6) steel wire rope of two crane lifting truss is hung on to the Heave Here of the steel truss of pre- lifting；
(7) by the crane track route figure woven, lifted slowly after truss lifting certain altitude, then by two cranes
Travel to the lower section of structures truss installa-tion；
(8) truss lifting is in place, and truss integral lifting exceeds the top of mounting seat, and adjustment is installed on base；
(9) truss and base are consolidated and are connected.
In above-described embodiment, the piece of smooth land in crane travel region is hardened according to step (2) crane track route figure, after hardening
The piece of smooth land, which is removed, need to do compacting factor experiment；While carrying out post training to crane operator and telling somebody what one's real intentions are in detail.
In (7) two crane walking processes of step, two cranes remain a constant speed it is forward, steel wire rope local direction swing in note
Crane collaboration of anticipating moves pendulum, it is ensured that steel wire rope and truss integral translation.
When step (8) lifting is in place, if two crane performance parameters are different, the one end for needing load-bearing big is first in place, then
The other end can be slowly in place.
In work progress, note also：
1st, must be according to the actual crane track route figure for lifting condition establishment in place, two crane walkings of hardening before constructing
The roadbed of circuit.
2nd, calculate every crane load-bearing, and after truss lifting two ends difference of height and angle, while to crane operation people
Member carries out post training and told somebody what one's real intentions are in detail, the crane smooth-ride after lifting, and control lifting at the uniform velocity, keeps purlin during lifting
The relative quiescent lifting of frame two ends, the angle allowed band that its truss two ends can not be calculated beyond it, this is that high large-span truss is whole
The key point that body shifting method is successfully lifted.
3rd, treat that truss two ends are effectively connected the errorless detachable steel wire rope in rear of confirmation with base by design drawing requirement.
