Description
Technical field
This utility model relates to the technical field of blower fan pylon, refers in particular to a kind of sectionally assembled concrete
Soil pylon structure.
Background technology
The most known, for improving the generating efficiency of low wind speed area wind power generating set, reduce wind shear, must
The hub centre height of Wind turbines must be improved.Conventional steel pylon is along with the raising of tower height, and it manufactures
Cost steeply rises, and tower bottom diameter is increasing, causes transport difficult.And use upper steel tower
This problem can well be solved with the combined tower of bottom concrete tower.Concrete tower is by some
Ring segment is spliced, and assembly carries out prestressed stretch-draw after completing, and forms a unified entirety.
In prior art, the connected mode between ring segment with ring segment is in ring segment joint the most corresponding reserved hole
Hole, during splicing, inserts between hole and connects reinforcing bar, toward concrete perfusion slurry in hole after docking, treat
After slurry solidification, two ring segment are just linked together by reinforcing bar.But, this connected mode quality of connection is not allowed
Easily ensure, inconvenient operation, and long construction period.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of sectionally assembled prefabricated mixed
Solidifying soil pylon structure, on the premise of ensureing pylon ring segment quality of connection, solves existing prefabricated concrete towers
The frame ring segment connection construction cycle is long, the problem of inconvenient operation.
For achieving the above object, technical scheme provided by the utility model is: a kind of sectionally assembled prefabricated
Concrete towers shelf structure, is used flange bolt to be connected in sequence by multiple ring segment, and passes through prestressing with bond
Muscle carries out pretension, makes concrete be in pressured state；Wherein, each ring segment all includes ring-type prefabricated mixed
Solidifying soil unit, embedded bar, embedded flange dish, the two ends of described precast concrete unit are provided with same with it
The first annular groove of the heart, described embedded flange dish is embedded into the first annular of precast concrete unit two ends
In groove, embedded flange dish is provided with the second concentric annular groove, the bottom land of the second annular groove
It is provided with the embedded bar passed for embedded bar and wears muscle hole and the prestressing with bond passed for internal presstressed reinforcing steel
Muscle wears muscle hole, and embedded bar is worn muscle hole and worn muscle hole interlaced arrangement with prestressing with bond muscle, described embedded bar
The two ends embedded flange dish from precast concrete unit two ends passes, by with nut screw connection by embedded method
Blue dish tightens together with precast concrete unit and is integrally formed.
Described embedded flange dish is provided with bolt hole, uses flange bolt to carry out ring segment connection by bolt hole,
And described flange bolt is arranged on inside pylon.
Described embedded flange dish is provided with the anchor bar that a row extend in concrete, described anchor bar
Circumferentially it is evenly arranged.
Described nut coordinate with embedded bar tighten after be contained in the second annular groove of embedded flange dish.
This utility model compared with prior art, has the advantage that and beneficial effect:
The ring segment of existing precast concrete tower and ring segment be connected by ring segment joint reserve multiple mutually
Corresponding hole, during docking, inserts between hole and connects reinforcing bar, toward concrete perfusion in hole after docking
Slurry, after slurry solidifies, two ring segment are just linked together by reinforcing bar.And the technical program uses flange spiral shell
Tether connection mechanism and carry out the connection between ring segment and ring segment, it is not necessary to carry out concrete grouting, the most significantly carry
High concrete tower efficiency of assembling, therefore construction period can be shortened, save time cost and hoisting cost.
Accompanying drawing explanation
Fig. 1 is single ring segment structural representation.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is two ring segment assembling schematic diagrams.
Fig. 4 is the precast concrete tower schematic diagram that multiple ring segment is formed by connecting.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
As shown in Figures 1 to 4, the sectionally assembled precast concrete tower structure described in the present embodiment, by
Multiple ring segment use flange bolt 9 to be connected in sequence, and carry out pretension by prestressing with bond muscle, make to mix
Solidifying soil is in pressured state；Wherein, each ring segment all includes ring-type precast concrete unit 1, pre-buried steel
Muscle 3, embedded flange dish 5, the two ends of described precast concrete unit 1 are provided with concentric first annular
Groove 4, described embedded flange dish 5 is embedded in the first annular groove 4 at precast concrete unit 1 two ends,
Embedded flange dish 5 is provided with the second concentric annular groove 6 and bolt hole 8, is adopted by bolt hole 8
Carry out ring segment connection with flange bolt 9, it is achieved quick assembling, in order to extend service life of connecting bolt with
And convenient for installation and maintenance, described flange bolt 9 is arranged on inside pylon, and this design can be avoided outside tower
The erosion to flange bolt of portion's adverse weather condition；The bottom land of described second annular groove 6 is provided with for pre-buried
Muscle hole 2 worn by the embedded bar that reinforcing bar 3 passes and the prestressing with bond muscle that passes for internal presstressed reinforcing steel wears muscle hole
10, embedded bar is worn muscle hole 2 and is worn muscle hole 10 interlaced arrangement with prestressing with bond muscle, described embedded bar 3
The two ends embedded flange dish 5 from precast concrete unit 1 two ends passes, by coordinating embedding with nut 11
Enter formula ring flange 5 to tighten together with precast concrete unit 1 and be integrally formed.
