[0005] Prestress is roughly classified into a pretension system and a post-tension system according to the time of introduction. In the pretension method, concrete is struck while giving tension to the PC steel, the PC steel is cut after the concrete is hardened, and the tensile force applied to the PC steel is applied to the concrete by bonding the PC steel to the concrete. This is a way to tell the prestress. On the other hand, the post-tension method adopted in the present invention is a method in which, after hardening of concrete, a tensile force is applied to a PC steel material to fix an end thereof to apply a prestress. In the case of the post-tension method, The arrangement of the PC steel material is free, and it has a feature that a large prestress can be easily introduced into cast-in-place concrete having various shapes. In addition, as a PC steel material, a PC steel wire,
PC steel strands, PC steel rods and the like are used, but those made of high-strength FRP can be used.

The concrete wind turbine support tower of the present invention is composed of a plurality of concrete tubular segments. Here, as the concrete for forming the segments, general concrete is used, but other concrete such as high-strength concrete or lightweight concrete can be used according to the application. In addition, although the segment is cylindrical, the cylindrical shape may be circular or a polyhedral structure.
When the cylindrical segment is manufactured by casting new concrete on the upper surface of the other pre-cast (precast) cylindrical segment, the joint surface between the upper and lower segments is constructed during the construction of the wind turbine support tower. However, it is needless to say that a separately manufactured mold may be used. If upper and lower end surfaces of the upper and lower cylindrical segments are formed with concave and convex surfaces such as a key portion and a key groove portion to be described later, these surfaces are overlapped (fitted) to ensure the upper and lower cylindrical segments can be easily secured.

[0007] A key portion and a key groove portion for preventing lateral displacement are formed on the upper end surface and the lower end surface of the cylindrical segment. The key portion and the key groove portion are in a relationship of a male type and a female type, and as the shape of the key portion, a convex surface is formed in a trapezoidal shape, the concave surface is an opposite shape, and the convex surface is fitted with concrete. The trapezoidal joint key, the convex surface of the key part is formed in a multi-stage shape,
A concrete multi-step joining key in which the concave surface has the opposite shape and the convex surface is fitted, a concrete corrugated joining key in which the convex surface is formed in a wavy shape, the concave surface has the opposite shape and the convex surface is fitted, and the convex portion is a pin. A steel joining key which is formed in a shape, has a round recess, and has a shape in which the pin is fitted. The key portion transmits force (shear force) in the longitudinal direction of the member and does not transmit force in the perpendicular direction, so a plurality of key portions are provided so that a shear force transmission effect can be expected for wind power from any direction. Have been. As described above, the force is not transmitted in the right angle direction. Therefore, when two keys are provided, the keys are not provided in a linear direction, that is, in a direction opposite to 180 degrees, and the arrangement is such that a shearing force transmission effect can be expected. In particular, it is desirable to provide three key portions, which are the most stable arrangement, at equal intervals.

According to the present invention, high durability is obtained and rigidity is improved by introducing prestress into a large number of concrete tubular segments constituting a concrete wind turbine support tower, so that high rigidity is obtained. There is no limit on the size, and a wind turbine support tower having a wide range of application can be constructed. In addition, by providing the key portion and the key groove portion on the joint surface between the concrete cylindrical segments, resistance to horizontal load is increased, and workability is improved. Furthermore, since the rigidity of the concrete windmill support tower is improved by the introduction of prestress, the amplitude due to the wind can be suppressed to a small value, and noise during operation of wind power generation or the like can be suppressed. According to the method for constructing a concrete wind turbine support tower of the present invention, since the construction is easy, the construction period can be shortened, and the material cost is low and the corrosion resistance is good, so that the construction cost and the maintenance management cost can be reduced.
