Description

Cast-in-place equal diameter prestressed concrete tower cylinder
Technical field
This utility model relates to a kind of concrete tower for wind-driven generator, is normal especially for top Rule steel tower, bottom are the cast-in-place equal diameter prestressed concrete tower cylinders of concrete tower type.It is applicable to Wind power generation field.
Background technology
Along with China's wind power industry is rapidly developed, Wind turbines single-machine capacity is increasing, runner Diameter is increasing, hub height is more and more higher.The supporting construction of traditional Wind turbines is steel circular cone Shape tower, sectional making, it is connected with, steel tower has good looking appearance, feature easy for installation, But the development maximized along with Wind turbines, for meeting stress and rigidity needs, the diameter of steel tower more comes The biggest, when hub height is more than 100m, the diameter of its end section tower is considerably beyond conventional highway transportation Arrowhead, thus limit Wind turbines maximize development.
The problem of transport difficult for solution large-scale wind electricity unit steel tower diameter is excessive, needs to reduce steel The height of tower, bottom tower will be changed into concrete tower by steel tower, and top tower still uses often The steel tower of rule, the steel tower on top reduces due to height reduction, stress, and its diameter just can meet The requirement of conventional highway transportation.The concrete tower of bottom owing to diameter is big, weight big, complicated construction technique, Concrete tower is in addition to needs meet structural strength and rigidity requirement, in addition it is also necessary to can transport easily and pacify Dress, and reduce investment outlay.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, it is provided that a kind of construction work Skill is simple, transport and easy for installation, cheap cast-in-place equal diameter prestressed concrete tower cylinder.
This utility model be the technical scheme is that a kind of cast-in-place equal diameter prestressed concrete tower cylinder, tool There are the steel tower on top and the concrete tower of bottom, it is characterised in that: this concrete tower includes coagulation The concrete barrel of the equal diameter equal thickness that earth foundation is connected with concrete foundation arc transition, and coagulation The top board at soil cylinder top;Be provided with the prestress wire of overcoat pillar in described concrete tube body, this pre-should The upper and lower end of power steel strand wires is anchored in top board top and concrete foundation respectively;Described top board is provided with even Connect the foundation bolt of steel tower.
Described concrete barrel is cast-in-place structural, and barrel diameter is 6~10m, and cylinder wall thickness is 400~800mm.
Described top board is cast-in-place structural, and thickness is 0.6~1.5m.
The overcoat pillar of described prestress wire is PE pipe or pvc pipe.
The strength grade of concrete of described concrete tower is C40~C60.
The beneficial effects of the utility model are:
1, this utility model uses the concrete barrel of equal diameter equal thickness, and this cylinder can use sliding formwork piecemeal Lifting construction, it is to avoid set up large-scale scaffold and a large amount of formwork erection, make whole cylinder construction technology simple, Speed is fast, cheap.
2, this utility model in cylinder preset prestress wire so that the intensity of whole concrete tower and Rigidity can be effectively guaranteed.
3, this utility model concrete barrel, concrete foundation are cast-in-place structural, and it connects simple, right Bottom concrete foundation does not has special requirement.
Accompanying drawing explanation
Fig. 1 is the profile of the present embodiment.
Fig. 2 is the plane graph of the present embodiment.
Detailed description of the invention
As shown in Fig. 1~2, the present embodiment is a cast-in-place equal diameter prestressed concrete tower cylinder high for 30m, Including steel tower and the concrete tower of bottom on top, this concrete tower is by the concrete connected successively Basis 2, the concrete barrel 1 of equal diameter equal thickness and top board 3 form.
Wherein, concrete barrel 1 is cast-in-place structural, use sliding formwork lifting construction piecemeal, except with concrete The connecting portion on basis 2 does outside transition in the arc-shaped connection, and remaining is equal diameter equal thickness.Barrel diameter Being 6~10m, cylinder wall thickness is 400~800mm, and the strength grade of concrete of cylinder is generally C40~C60; The a diameter of 8m of this example, wall thickness is 500mm, and strength grade of concrete is generally C50.In concrete tube body in advance If prestress wire 4, its lower end anchors in concrete foundation, and upper end anchors on top board top;In advance should Power steel strand wires 4 overcoat pillar, pillar typically can use PE pipe or pvc pipe, for reducing prestress wire And the friction between pillar wall, prestress wire 4 is first oiling before presetting.
Top board 3 is provided with the foundation bolt 5 that the steel tower with top is connected, and uses cast-in-place structural, its thickness Generally 0.6~1.5m, the strength grade of concrete of top board is generally C40~C60;This example thickness is 1.0m, Strength grade of concrete is also C50.
In the present embodiment, after concrete barrel 1, concrete foundation 2 and top board 3 have all been poured, right Prestress wire 4 carries out stretch-draw and anchors.
The present embodiment is the equal diameter concrete tower of a section, and this utility model can be used for Multi-section concrete Tower is connected height, and the concrete tower of single hop uses equal diameter, different sections can use different-diameter.
