Abstract
The utility model provides a hot-rolled high-strength anchor bolt for a wind power foundation. Transverse ribs are spirally distributed on the total body of the anchor bolt and are rightward, so that a nut can be directly screwed on the anchor bolt. Pitches among the transverse ribs of the anchor bolt are reduced, and the accuracy requirement of the pitches among the transverse ribs is increased. Because threads on the total body of the anchor bolt strengthen bond stress between a reinforcing steel bar and concrete, the strength of the structure of the total reinforcing steel bar is improved. The hot-rolled high-strength anchor bolt is machined by the screw reinforcing steel bar without longitudinal ribs. In addition, the hot-rolled high-strength anchor bolt is formed at one step in a hot-rolled manner, complex work procedures including machining and lathing of two ends of the anchor bolt and heat treatment are omitted, cost is saved, and a manufacturing process is low-carbon and environment-friendly; strength loss is avoided when the transverse ribs of the anchor bolt are rolled, and the hot-rolled high-strength anchor bolt is superior to a bolt which is formed by machining and lathing two ends of a round bar; and the threads of the total body of the anchor bolt are combined with the concrete, so that the bond stress is increased, the total body strength and the like are high, using safety is guaranteed, adjustment accuracy is high, and the anchor bolt is flexible in use and can be cut off optionally during use.
Description
Technical field
The utility model belongs to the wind-powered electricity generation basis and makes the field with the anchor pole bolt, especially relates to a kind of wind-powered electricity generation basis with hot rolling high strength anchor bar bolt.
Background technique
The anchor pole bolt that uses is at present processed screw buckle after-baking at two ends through the machining car as hot rolling pole material and is accomplished; Complex procedures, cost height; Have only a few producer to process at home, mainly by U.S.'s import, its price is per ton up to more than 10,000 yuan of RMB.
Summary of the invention
The purpose of the utility model provides a kind of saving cost, working process low-carbon (LC), environmental protection, and cross rib does not have loss of strength, and the whole body intensity etc. are strong, safe, and the adjustment precision is high, use flexibly, but the wind-powered electricity generation of intercepting random lengths basis is with hot rolling high strength anchor bar bolt.
The technological scheme of the utility model is: a kind of wind-powered electricity generation basis is with hot rolling high strength anchor bar bolt; It is characterized in that: a kind of wind-powered electricity generation basis is to adopt the vertical rib spiral reinforcement processing of the nothing similar with common finish rolling thread profile with hot rolling high strength anchor bar bolt, and the wind-powered electricity generation basis all over is provided with cross rib with hot rolling high strength anchor bar bolt, and cross rib is in spiral distribution; Direction is dextrorotation; Can directly screw in nut, said cross rib cross section is trapezoidal, and the wind-powered electricity generation basis is controlled at ± 0.2mm with hot rolling high strength anchor bar bolt inner diameter vertical height tolerance; The horizontal tolerance of internal diameter is controlled at+0.2～-0.4mm, out of roundness is not more than 0.3mm.
Advantage and the good effect that the utlity model has are: working process low-carbon (LC), environmental protection, and cross rib does not have loss of strength, and the whole body intensity etc. are strong, safe, and the adjustment precision is high, uses flexibly, but the intercepting random lengths.

Fig. 3 is the utility model cross rib cross sectional representation.
Among the figure:
1, cross rib, 2, the cross rib side, 3, rebar surface, 4, reinforcing bar.
Embodiment
Like Fig. 1,2,3 the utility model structural representations, the utility model cross-sectional structure schematic representation is shown in the utility model cross rib cross sectional representation; A kind of wind-powered electricity generation basis is with hot rolling high strength anchor bar bolt; It is characterized in that: a kind of wind-powered electricity generation basis is to adopt vertical rib spiral reinforcement 4 processing of the nothing similar with common finish rolling thread profile with hot rolling high strength anchor bar bolt, and the wind-powered electricity generation basis all over is provided with cross rib 1 with hot rolling high strength anchor bar bolt, and cross rib 1 is in spiral distribution; Direction is dextrorotation; Can directly screw in nut, said cross rib 1 cross section is trapezoidal, and the wind-powered electricity generation basis is controlled at ± 0.2mm with hot rolling high strength anchor bar bolt inner diameter vertical height tolerance; The horizontal tolerance of internal diameter is controlled at+0.2～-0.4mm, out of roundness is not more than 0.3mm.
The working procedure of this instance: the anchor pole bolt with φ 40 is an example, its cross rib 1 spacing L=8 ± 0.05mm, angle=70 of cross rib side 2 and rebar surface 3 ° ± 10 °, cross rib 1 height h=2.0 ± 0.3mm, cross rib 1 bottom width b=2.0 ± 0.3mm.Cross rib 1 spacing is dwindled, and for guaranteeing the intensity of nut, its gap value is not more than 0.5mm, helps the fastening of nut like this, improves anchor force.The increase of the angle angle of cross rib side 2 helps fastening with nut equally.For satisfying the high tenacity of anchor pole bolt, on rolling reinforcing bar material, selected the Bainitic Steel raw material, through after the hot rolling, carry out low temperature isothermal transformation heat treatment, make the yield strength of reinforcing bar be increased to 900MPa and more than the 1080MPa, and the homogeneity of reinforcing bar is good.Use the anchor pole bolt as P&H Tensionless filling pile basis,, be covered with the anchor pole bolt in one week of post-stretching hollow concrete cylindrical body, the buried degree of depth at 9～11m, top is connected with blower fan pylon, and is through the autofrettage of posttension daraf(reciprocal of farad), fastening with supporting nut.Realization can improve the requirement of basic prestressed reinforced concrete structure intensity, can play the effect of fastening top blower fan pylon again.
Above mode of execution is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
