Description
Technical field
The present invention relates to a kind of method at aerial regulation steel truss mast-up angle of inclination.
Background technology
The project under construction of steel truss structure fabrication and installation generally existing in large scale industry Facilities Construction.Because function needs
Will, most of truss structure installation has angle of inclination, but steel truss, in lifting, angle of inclination is difficult that adjustment is accurate.
Angle of inclination when steel truss lifts, traditional regulation method are the length differences by truss both ends steel wire ropes away from adjusting
Save angle of inclination.The adjusting method angle of inclination error is big, is difficult to control, and can produce the hard collision of truss and steel column,
Easily cause steel frame deformation impaired and mechanical wounding, danger are big.
The content of the invention
In order to solve technical problem present in prior art, the invention discloses a kind of aerial regulation steel truss to hang the present invention
The method for shelving angle of inclination, facilitate steel truss accurately to install in place, reduce hoisting process danger, improve lifting efficiency.
The technical solution adopted by the present invention is as follows：
A kind of method at aerial regulation steel truss mast-up angle of inclination, comprises the following steps：
Step 1 is respectively connected two suspension centres of steel truss one end and the steel wire rope of suspention using two length adjustment devices
Connect；The other end is then directly to be connected with steel wire rope with two suspension centres；
Step 2 hangs a line pendant vertically downward on described steel truss；
Step 3 marks wherein heart line on the steel column of one of them vertical stress of steel truss；
Step 4 relies on the tensile elongation regulation to length adjustment device to realize that line falls after steel truss lifts by crane and departs from ground
With the regulation of the angle of steel column center line, finished when line falls with the coincidence of steel column center line or parallel i.e. steelframe angle of inclination regulation,
Can directly it lift in place.
Further, described length adjustment device is bottle gouard moved by hands.
Further, the steel column described in step 3 refers to after steel truss rigging out, it is necessary to the steel of vertical stress
Post；Because general truss has many diagonal braces, these diagonal braces be as a rule do not stress or stress nor vertically by
Power, and heretofore described steel column is then the steel column for needing vertical stress.
Further, the steel column of described mark center line is the steel column being easily observe that in selection steel truss and is easy to draw
The steel column of line.
Further, can select to be located at end and outermost steel column.
Further, described line pendant hangs on the end of steel truss.
The present invention is realized to steel truss mast-up by way of marking center line and suspention line pendant on steel column in advance
The regulation at angle of inclination.
Beneficial effects of the present invention are as follows：
1st, the present apparatus is simple in construction, easy to operate, low without complicated, valuable component, manufacturing cost.
2nd, present apparatus using flexible, it is workable, it is easy to being widely implemented for the technology.
Brief description of the drawings
The Figure of description for forming the part of the application is used for providing further understanding of the present application, and the application's shows
Meaning property embodiment and its illustrate be used for explain the application, do not form the improper restriction to the application.
The schematic diagram that two suspension centres of Fig. 1 steel truss one end are connected with steel wire rope；
Structural representation after the completion of the lifting of Fig. 2 steel truss.
Embodiment
It is noted that described further below is all exemplary, it is intended to provides further instruction to the application.It is unless another
Indicate, all technologies used herein and scientific terminology are with usual with the application person of an ordinary skill in the technical field
The identical meanings of understanding.
It should be noted that term used herein above is merely to describe embodiment, and be not intended to restricted root
According to the illustrative embodiments of the application.Additionally, it should be understood that when in this manual use term "comprising" and/
Or during " comprising ", it indicates existing characteristics, step, operation, device, component and/or combinations thereof.
Term explains part:Heretofore described steel column refers to after steel truss rigging out, it is necessary to vertical stress
Steel column；Because general truss has many diagonal braces, these diagonal braces be as a rule do not stress or stress nor hang down
Straight stress, and heretofore described steel column is then the steel column for needing stress.
As background technology is introduced, angle of inclination during steel truss lifting, traditional regulation side in the prior art be present
Method is the length difference by truss both ends steel wire ropes away from adjusting angle of inclination.The adjusting method angle of inclination error is big, is not easy
Control, and can produce the hard collision of truss and steel column, easily cause steel frame deformation impaired and mechanical wounding, dangerous big,
It is convenient present applicant proposes a kind of method at aerial regulation steel truss mast-up angle of inclination in order to solve technical problem as above
Accurately installation is in place for steel truss, reduces hoisting process danger, improves lifting efficiency.
In a kind of typical embodiment of the application, as shown in Figure 1, there is provided a kind of aerial regulation steel truss mast-up inclines
The method of rake angle：It is specific as follows：
Conventional hanging method is four suspension centres, is directly lifted with rope traction respectively.The design is pulled using two
Two suspension centres of steel truss one end are connected by cucurbit with steel wire rope respectively, as shown in Figure 1：
Then a line pendant vertically downward is hung on described steel truss；The position of the suspension of line pendant can be located at purlin
The end of frame or the other positions of steel truss, it can be selected according to the actual conditions at scene.
Again, wherein heart line is marked on the steel column of one of them vertical stress of steel truss；Described mark center line
Steel column selection steel truss in the steel column that is easily observe that, and easily operated steel column, can typically select to be located at outermost
Steel column, so convenient operation；
Relied on after steel truss lifts by crane and departs from ground to tensile elongation and the line pendant of chain block and the folder of steel column center line
Angle adjusts the angle of inclination of steel truss, is that the regulation of steelframe angle of inclination finishes when line pendant overlaps (or parallel) with steelframe center line,
Can directly it lift in place, as shown in Figure 2；
As can be seen from the above description, the application the above embodiments realize following technique effect：
1st, the present apparatus is simple in construction, easy to operate, low without complicated, valuable component, manufacturing cost.
2nd, present apparatus using flexible, it is workable, it is easy to being widely implemented for the technology.
Although above-mentioned the embodiment of the present invention is described with reference to accompanying drawing, model not is protected to the present invention
The limitation enclosed, one of ordinary skill in the art should be understood that on the basis of technical scheme those skilled in the art are not
Need to pay various modifications or deformation that creative work can make still within protection scope of the present invention.
