The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
With reference to Fig. 1, Fig. 2 and Fig. 3, tower basis is adjustable positioning anchor cage, comprising:
One upper flange 100, one lower flanges 200, and run through the anchor pole 300 of upper flange 100 and lower flange 200, and upper and lower flange 100,200 is concentric with basis;
One arranges the built-in fitting fixing hole 201 on lower flange 200, and lower flange carrying bolt 204 runs through built-in fitting fixing hole 201 afterwards and built-in fitting 400 is located by connecting, and built-in fitting is the fixture in a Transducers Embedded in Concrete.
Anchor pole 300 is by several parallel arrangements, and the prestressed anchor 301 being fixed on upper and lower flange forms, and the lower end of prestressed anchor 301 connects a half-nut 302, and upper end connects a nylon adjusting nut 303, and nylon adjusting nut 303 is close to upper flange lower end;
Wherein prestressed anchor 301 upper ends are a conehead, are generally 45 ° of pointed cones 304; Prestressed anchor 301 lower ends are butt end 305.
A sheathed PVC sleeve pipe 500 on prestressed anchor 301, PVC sleeve pipe 500 lower ends arrange a bit of heat-shrink tube 600, and the heat-shrink tube 600 after heating shrinks the gap of shutoff PVC sleeve pipe and prestressed anchor; PVC sleeve pipe 500 tops are placed in the bolt hole of upper flange 100, and apart from the bolt hole 102 end face 5-10mm of upper flange.
In positioning anchor cage, be provided with four location lacing wires with flower basket bolt, for location and the regulating action of anchor cage.
Lower flange carrying bolt 204 comprises a bolt 205, and a built-in fitting 206 being connected with bolt 205, and built-in fitting 206 is a semiarc shape, and radian is 30 degree.
Concrete mounting process of the present utility model is as follows:
The installation of lower flange: according to the requirement of prestressed anchor foundation drawing, whether built-in fitting quantity, size and the position of checking installation lower flange be correct.
First, select suitable crane, after lower flange is sling, slowly move to 300mm place, built-in fitting top and stop, first lower flange carrying bolt correspondence is penetrated in the screw on lower flange, lower flange is respectively put a nut up and down, adds a pad on the nut below lower flange.Inside and outside carrying bolt is aimed at after built-in fitting, and crane is placed on lower flange on built-in fitting.The distance that on lower flange, plane arrives built-in fitting is according to basic Design Requirement Drawing.The corresponding base center, center of lower flange, permission maximum deviation is 5mm;
Then, by lower flange carrying bolt and corresponding built-in fitting firm welding, foot welding height is not less than 6mm.
Finally, regulate carrying bolt, make lower flange reach layout design absolute altitude, and the levelness of lower flange is no more than 3mm.
The installation of anchor pole: all prestressed anchor is put neatly, and the half-nut of blackout of screwing in the lower end of prestressed anchor (butt end), blackening process can play effect antirust and attractive in appearance;
The lower end of prestressed anchor to half-nut has a segment distance, then PVC sleeve pipe (length by drawing) is inserted in to anchor pole, then heat-shrink tube is enclosed within on PVC sleeve pipe;
In the upper end of prestressed anchor (conehead end), be screwed into nylon adjusting nut (not allowing to use steel nut),
The installation of upper flange
With crane, by the upper flange certain altitude of slinging, the upper and lower station of the side people near foundation ditch limit, then on the inside and outside bolt hole of upper flange, uniform symmetry is put on prestressed anchor, and prestressed anchor is with temporary steel nut after penetrating upper flange.
After prestressed anchor is put on, crane slowly sling upper flange and location anchor pole, move to directly over lower flange, prestressed anchor is penetrated in corresponding lower flange bolt hole, below lower flange, after shell tool, tighten the whole nut of blackout (must not misuse Dacroment nut).Nut screwing clamping moment requires as 300Nm.
Fixed one of (on natural terrace surface) every 60 ° of positions, blower foundation outside, then with the dilatory rope that flower basket bolt is housed, upper flange is connected with stake, regulate the flower basket bolt of four direction, (center line above, lower flange bolt hole is benchmark with one heart to make upper and lower flange, with transit, survey verticality, survey altogether 4 points, every 90 ° of points, make upper and lower flange concentric, should meet≤3mm of concentricity allowable variation).
After upper and lower flange is concentric, adjust the levelness of upper flange: the levelness of measuring plane shell ring docking region on prestressed anchor place upper flange, regulate nylon nut and temporary steel nut to make plane on upper flange reach layout design absolute altitude, before should meet≤1.5mm(of upper flange levelness concreting).
After adjustment finishes, every PVC sleeve pipe upper end is penetrated to the interior about 5-15mm left and right of stomidium (forbidding PVC sleeve pipe to pass plane on upper flange) under upper flange, then with the heat-shrink tube at alcohol blast burner heating PVC sleeve port place, make it shrink the gap of shutoff PVC sleeve pipe and anchor pole.
After adjustment finishes, strengthen the adjustable positioning anchor cage in tower basis with 4 reinforcing bars (both direction, each direction are cross).The welding of reinforcing bar upper end and upper flange, weld with basic built-in fitting lower end, and in the joint firm welding of 4 reinforcing bars, strengthen the resistance to overturning of the adjustable positioning anchor cage in tower basis.
After reinforcing bar binding, formwork, before concreting, should check the levelness of upper flange, reach after requirement, can fluid concrete.
Concrete should adopt poker vibrator to vibrate, and discharges air, guarantees concrete vibrating closely knit (the every layer of thickness that vibrates of every rod that vibrates should not be greater than 300mm).Should pay attention to especially the concrete pouring quality in upper flange below and lower flange top, should vibrate in the each interval of upper and lower flange anchor pole.During concreting, should prevent that template is subjected to displacement or tilts, avoid occurring running pulp (recommendation steel template).
In sum, in actual use, owing to adopting anchor slab and lower anchor slab in segmented, in segmented, anchor slab and lower anchor slab need to carry out scene and splice, and the job site duration is easily incured loss through delay, and differ and reach surely very high precision; And adjustable crab-bolt support is installed, the anchor cage level in site operation process is regulated, complex structure, and in connection segment formula, crab-bolt sleeve pipe is used in the crab-bolt outside of anchor slab and lower anchor slab;
Upper flange of the present utility model and lower flange are one-body molded, need not on-the-spot splice; And on upper flange, be provided with nylon adjusting nut, and support upper flange and carry out the leveling work of upper flange plate with nylon adjusting nut, reduced so on-the-spot construction sequence, reach construction more convenient; Have simple in structure, the feature of easy construction.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
