Detailed description of the invention
As shown in Fig. 1～5, the present embodiment is that hypomere precast concrete tower 1 is connected with epimere steel tower tube 4
Attachment structure, this attachment structure mainly by end steel plate 15, connecting bolt 2, be positioned at concrete tower 1 with
Concrete leveling layer 3 between steel tower tube 4 forms.
Precast concrete tower 1 top is provided with end steel plate 15, and this end steel plate is used for undertaking upper steel tower 4
The whole load handed down.The end steel plate 15 prestress wire 11 in being embedded in concrete towers cylinder 1 in advance is solid
Due to concrete tower 1 end face, above this end steel plate, perfusion forms concrete leveling layer 3, concrete leveling layer
Installing steel tower tube 4 on 3, end steel plate 15 and steel tower tube 4 are by being embedded in the connection in concrete leveling layer 3 in advance
Bolt 2 is connected.
This example middle-end steel plate 15, as the anchor slab of prestress wire 11, also serves as connecting bolt 2 simultaneously
Lower flange, this end steel plate 15 uniformly has some bolts hole 18, steel strand wires perforation 16 and concreting
Hole 17, prestress wire perforation 16 is for through prestress wire 11, the chi in concreting hole 17
Very little generally 100～200mm, blanking when casting concrete and vibrating.In precast concrete tower 1
Prestress wire 11, be provided with sleeve pipe 12 outside prestress wire 11, end steel plate 15 above
Arranging the anchor 13 of prestress wire 11, prestress wire 11 anchors on end steel plate 15.In advance
In concrete tower 1 processed, longitudinal reinforcement 14 welds with end steel plate 15, strengthens the stress performance of tower concrete.
Connecting bolt 2 lower end is fixed on end steel plate 15, arranges lower nut 21 in the bottom of end steel plate 15,
Lower nut 21 is double caps (two identical nuts), between the two nut and nut and end steel plate 15
Between with spot welding connect, for hold-doun nut.The helmet 24 of lower nut 21 outer sheath rubber, is used for separating
Connecting bolt 2 and tower concrete.At the threaded upper cap nut of connecting bolt 2 22 on end steel plate 15 top,
Upper cap nut 22 is single cap, for connecting bolt 2 and end steel plate 15 being fixed.Outside connecting bolt 2
The sheath 25 of side set rubber, for separating connecting bolt 2 and the concrete in concrete leveling layer 3.Even
The upper end of connecting bolt 2 coordinates steel tower tube nut 23 to be connected with the lower flange of steel tower tube 4, in steel tower tube 4 purgation
Arranging steel tower tube nut 23 on orchid, steel tower tube nut 23 is also double caps, outside steel tower tube nut 23
The anticorrosion helmet 26 of set rubber, for bolt anti-corrosion.
Backplate 31 is set outside concrete leveling layer 3, the inside/outside diameter size phase of backplate 31 and concrete tower 1
With, backplate 31 welds with end steel plate 15, the backplate 31 template when concrete perfusion screed-coat 3, also
Lateral force structure as concrete leveling layer 3.
The sequence of construction of the present embodiment is:
1, before concrete tower 1 stack shell concreting, by end steel plate 15, connecting bolt 2, connecting bolt
Sheath 25 and the backplate 31 of concrete leveling layer 3 be placed in the top of concrete tower 1, stack shell coagulation
Soil pours afterwards and concrete tower 1 forms an entirety.
2, after uppermost concrete tower 1 lifting, stretch-draw prestressing force steel strand wires 11, on end steel plate 15 top
Anchor 13 is set, prestress wire is anchored.
3, after prestress wire 11 has anchored, the flatness of backplate 31 is measured, if out-of-flatness, and will note
Slurry backplate 31 surface rubbing, to ensure the flatness on backplate 31 surface, then positions connecting bolt for mould
Plate 27 is fixed on connecting bolt 2 above (Fig. 4), connecting bolt locating template 27 size and steel tower tube 4 times
The size of flange is identical, to ensure the installation accuracy of connecting bolt 2.
4, in the space that end plates 15 and backplate 31 surround, high-strength concrete is irrigated behind connecting bolt 2 location
Forming concrete leveling layer 3, strength of high strength concrete grade is between C60～C120, for self-leveling concrete,
Its perfusion face and neat face, backplate 31 surface.
5, after concrete leveling layer 3 reaches design strength, removing connecting bolt locating template 27, it is unnecessary to cut
Sheath 25, steel tower tube 4 is installed, stretch-draw connecting bolt 2 also installs steel tower tube nut 23 and anticorrosion helmet 26,
Connection completes.
