Specific implementation mode
In order to enable those skilled in the art to better understand the solution of the present invention, below in conjunction in the embodiment of the present invention
Attached drawing, technical scheme in the embodiment of the invention is clearly and completely described.Obviously, described embodiment is only
A part of the embodiment of the present invention gives presently preferred embodiments of the present invention instead of all the embodiments in attached drawing.The present invention can
To realize in many different forms, however it is not limited to embodiment described herein, on the contrary, provide the mesh of these embodiments
Be to make the disclosure of the present invention more thorough and comprehensive.Based on the embodiments of the present invention, the common skill in this field
The every other embodiment that art personnel are obtained without creative efforts belongs to the model that the present invention protects
It encloses.
Refering to fig. 1, in embodiments of the present invention, a kind of cable tension method of truss string structure is provided, the method is used
Drag-line in accurately installation steel truss building, specifically includes step：
S1：By engineering design requirements in the assembled good inverted triangle frame of predetermined position；
In conjunction with Fig. 2, in embodiments of the present invention, inverted triangle frame 21 is installed on two columns 22, and is pacified between two columns 22
On a preset pedestal, meanwhile, moving trolley is arranged in the underface of inverted triangle frame, the side of convenient then stretching rope
Convenient to operate.
S2：Drag-line is placed to suitable position with reference to the position of the inverted triangle frame, and cord clip is installed in predetermined position；
In embodiment, it again, is considered as special rope turntable of putting since guy cable length is long and puts rope.Putting rope process
In, because of the eccentric force of the elasticity and traction generation of rope disk itself, the rotation of rope disk can make to generate acceleration when turntable, cause to dissipate disk, easily
Jeopardizing safety of workers, being had to when because putting rope slowly, at the uniform velocity, brake gear is arranged in turntable when necessary；Meanwhile it being put down by Suo Yunzhi
After lying under the up-side down triangle arch of assembled forming, cord clip is transported under each corresponding strut node, organizing construction personnel press
Installing Cable-clamp position of the original mark on cable body carries out the installation of cord clip.
Preferably, drag-line is implemented to put rope operation by dedicated rope turntable of putting.
Preferably, the collar extension of cord clip is designed to the changeover portion of a round and smooth shape by the embodiment of the present invention, to protect drag-line
External protective case, to achieve the effect that extend drag-line service life.
S3：Hauling rope is set according to the placement location of the drag-line, while by traction enhancement jack according to design requirement
It is suitably positioned；And fix the rope head of the drag-line, tensioning hauling rope, while cord clip is snapped onto into predeterminated position
Place realizes tension operation.
Specifically, since drag-line is long and heavy, and the shape of drag-line is in fish belly shape, according to this feature, the special peace by drag-line
The both ends that dress method is thought of as rope screw on drawing head, use steel strand wires as hauling rope, and steel strand wires first penetrate support lug, in truss
Both ends pull hauling rope with punching hydraulic jack, complete drag-line and are promoted.
In conjunction with Fig. 3, in embodiments of the present invention, when tensioning drag-line, realized by a tension operation platform 1, a is in figure
The vertical view of tension operation platform, b be tension operation platform side view, further, tension operation platform include cat ladder 11,
Safety barrier 12, reinforced support 13 and top supporting frame 14；After setting tension operation platform 1, installed at suitable position
Jack supporting rack, tool pull rod and steel spike；Meanwhile during tensioning drag-line, using Software of structural computation and analysis into
Row auxiliary calculates analysis, least favorable state when rope being selected to draw to design position（Curve radian is minimum）Establish structural model into
Row calculates.
In embodiments of the present invention, after the installation of traction enhancement jack is in place, you can tensioning hauling rope carries drag-line
It rises；In lifting process, with the target in order to control of the cord clip position among span, when promoting cable body and close to each strut lower end,
First the rope head of one end is promoted and introduces in support lug and is fixed with axis pin, and is gradually drawn to the stretching end of rope head；Start purlin
Cord clip is connect by the oil pump of frame one end with strut one by one from rope head one end to the other end, promotes cord clip with chain block when necessary,
Strut is rotated, cord clip is made to be caught in strut lower end；Meanwhile before tensioning hauling rope, to the key of assembled up-side down triangle arch
Point is monitored, and is surveyed and is read initial value, wherein the liftoff height of the distance and terrain clearance and arch peak between two arch springing bearings
Degree must survey reading.To monitor the midpoint of rope as key in installation, finely tune at any time.
In embodiment, when cable tension, dual control is carried out to displacement and Suo Li, reaches the control node position that design side proposes
It moves and drag-line internal force requires, within the scope of its allowable error；For truss string structure after installation is complete, the stretching end of drag-line should remain can
The state of adjusting, to be adjusted when needed to the pulling force of drag-line；Specifically, the stretching process of the drag-line passes through
Mobile Ping Fache is implemented, and is provided with the mobile Ping Fache of limited quantity, installs preset distance setting between any two.
In design scheme provided by the invention, a kind of method for stretching of drag-line between large-span truss is provided, choosing is passed through
It selects and suitably puts rope turntable and the drag-line platform of hauling rope, cord clip and installing safety, cooperation thousand are set in preset position
Equipment, the drag-lines such as jin top, mobile Ping Fache can be installed accurately according to design position, to make drag-line in entire engineering
Maximum effect can be played in project；Method letter provided by the invention has prodigious operability, in the work for being related to drag-line
In journey project, a kind of quickly and effectively installation method can be provided, to ensure that constructs is normally carried out, is worth promoting.
The foregoing is merely a prefered embodiment of the invention, the scope of the claims of the present invention is not intended to limit, although with reference to aforementioned reality
Applying example, invention is explained in detail, still can be to aforementioned each tool for those skilled in the art comes
Technical solution recorded in body embodiment is modified, or carries out equivalence replacement to which part technical characteristic.Every profit
The equivalent structure made of description of the invention and accompanying drawing content is directly or indirectly used in other related technical areas,
