Specific embodiment
As shown in Figure 1, blower foundation cast-in fixing bolt sub-assembly (calling anchor bolt cage in the following text) used by the present embodiment, including annular
Upper anchor slab 1, annular lower anchor slab 3, multiple anchor bolts, bottom adjust bolt 4.
Anchor bolt includes anchor pole 2, and the upper and lower part of anchor pole is provided with screw thread, is equipped with anchor sleeve from top to bottom outside anchor pole 2
Pipe 7, locking nut 8, gasket 9 and bottom connect big nut 10.Locking nut 8 connects big nut 10 with bottom and is respectively at annular
Lower anchor slab 3 two sides up and down.
Having part in multiple anchor bolts is the anchor bolt that can serve as leveling and position upper anchor slab, and the anchor pole top of these anchor bolts also covers
There is upper anchor slab nylon adjusting nut 6.
T-nut 5 is additionally provided with outside the anchor pole of anchor bolt.
Upper anchor slab 1 has anchor hole 11, and passes through for anchor pole 2.
Anchor bolt cage adjusts bolt 4 by 6 pairs of bottoms to control whole levelness, while can be to the embedding of entire anchor bolt cage
Depth is finely adjusted；Anchor pole 2 realizes the anchoring to wind-driven generator tower by lower anchor slab 3, utilizes 8 He of locking nut of upper end
Anchor pole 2 is fixed on lower anchor slab 3 by the gasket 9 and big nut 10 of lower end；Upper anchor slab 1 is temporary fastening device, is poured to basis
It removes after the completion, the purpose is to position to all anchor poles 2, guarantees relative position and the blower fan tower barrel bottom flange of anchor pole 2
Eyelet match, while guaranteeing that anchor pole 2 is vertical, it is ensured that after tower is in place, stress condition when carrying out 2 tensioning of anchor pole with set
Meter condition is consistent.Upper anchor slab T-nut 5 is matched with upper anchor slab nylon nut 6, realizes height and level to upper anchor slab 1
Degree is adjusted, and realizes the fixation to the fixation of upper anchor slab 1 and to entire anchor bolt cage, prevents it from integral inclined and torsion occurs.
Above-mentioned T-nut 5 includes nut portions and intussusceptum 50, and intussusceptum 50 and upper anchor slab 1 are in clearance fit shape, described
T-nut 5 be used as male member, upper anchor slab 1 be used as female members, maximal clearance 1mm, minimum clearance 0.5mm, and T-nut 5 and
The eyelet of anchor slab 1 is concentric in correspondence, as shown in Figure 4.
Above-mentioned wind driven generator base bolt assembly installation method is as shown in figure 5, details are as follows:
One, lower anchor slab installation and leveling
Lower anchor slab 3 is mounted on 11 bottom of foundation pit by adjusting bolt 4 relative to 3 centrosymmetric six pairs of bottoms of lower anchor slab
On bed course built-in fitting 12 on.Lower anchor slab is adjusted in same level by adjusting bolt 4, passes through up and down adjustment tune
It saves bolt 4 and is locked with the nut adjusted on bolt, so that entirely lower anchor slab 3 is in same level, this is that the first step is thick
It adjusts.The center of lower anchor slab corresponds to base center, and permission maximum deviation is 5mm.Measurement meet the requirements after will adjust 4 bottom of bolt with
Corresponding 12 firm welding of built-in fitting, foot welding height are not less than 6mm.The nut on bolt 4 is adjusted later, and up and down adjustment adjusts spiral shell
Bolt 4 so that entirely lower anchor slab is in same level, and is adjusted to design altitude, this is second step accurate adjustment, reaches lower anchor slab
To layout design absolute altitude, and the levelness deviation of lower anchor slab is no more than 3mm.
Two, upper anchor slab installation leveling and anchor bolt installation
Before the installation of upper anchor slab 1, the positioning adjustment for first lifting six pairs of anchor bolts for installation is used.Every anchor component in addition to
Outside anchor pole 2, on sequence from top to bottom are as follows: nylon adjusting nut 6, anchor pole casing 7, locking nut 8.By the rotation of nylon nut 6 to setting
The installation site of the installation site of meter drawing requirement, anchor pole casing 7 and locking nut 8 determines naturally.Six pairs of positioning are adjusted
Anchor pole 2 penetrates in the bolt hole of corresponding lower anchor slab 3, and connection big nut in bottom is tightened after shell tool 9 below lower anchor slab 3
10.Then upper anchor slab 1 is slowly sling with crane, is slowly moved to above six pairs of positioning adjustment anchor bolts, and put down anchor
Plate 1.Take human assistance mode that upper anchor slab 1 is slowly fallen on to 6 top of nylon nut at the top of six pairs of positioning adjustment anchor bolts.Upper anchor
Plate 1 install it is in place after, the T-nuts 5 at the top of six pairs of positioning adjustment anchor bolts are installed, using nylon attaching nut 6 to upper anchor slab 1 into
T-nut 5 is tightened after the preliminary leveling of row.
Three, the installation and adjustment of anchor component
After the completion of upper anchor slab 1 is in place, the mode of being symmetrically installed is taken to carry out the installation of remaining anchor component.Wherein, it selects
Another six pairs of anchor poles of circumference are uniformly distributed in as tie down screw, they adjust spiral shell by the anchor pole of tensioning, will not to install nylon
Mother 6, is mounted directly upper end T-nut 5.Upper anchor slab 1 is adjusted using the dilatory rope of auxiliary, keeps anchor slab 1, lower anchor slab 3 same
The heart (the above anchor slab 1,3 bolt hole of lower anchor slab center line on the basis of, every 60 ° of points, altogether survey 6 points, make anchor slab 1, under
With one heart, concentricity tolerance should meet≤3mm to anchor slab 3).
After concentricity is adjusted, the levelness of upper anchor slab 1 is adjusted using nylon adjusting nut 6: measurement adjusts upper anchor slab 1
Anchor bolt middle levelness inside and outside upper plane, adjusting nylon adjusting nut 6 makes plane on cope plate reach layout design absolute altitude, mould
Plate ring levelness should meet≤1.5mm(concreting before).Upper 1 length of anchor slab is exposed in 2 upper end of anchor pole should meet drawing requirement.
After adjustment, big nut 10, screw-down torque 300Nm are further tightened, while tightening T-nut 5.
Finally, carrying out tensioning using moment method to aforementioned six pairs of tie down screws, tensioning torque is 200 Nm, to reinforce anchor
The overall stiffness and stability of bolt cage have stronger anti-construction disturbance ability in the case where not by volume external fixer.
After anchor bolt cage is installed, after reinforcing bar binding, formwork, the levelness of anchor slab should be checked before concreting,
After reaching requirement, concrete can be poured.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of skill in the art that its according to
It can so modify to technical solution documented by previous embodiment, or part of technical characteristic is equally replaced
It changes；And these are modified or replaceed, various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
Spirit and scope.
