Problems solved by technology

Therefore, in the invention described in Patent Document 4, as a foundation structure of a tower-shaped structure whose top elongates to a high position in the sky like a windmill tower, there is a possibility that sufficient durability cannot be provided. , it can be said that it is not enough to ensure sufficient endurance only for the cone failure that is a problem in the foot of the reinforced column described in Patent Document 4

Embodiment Construction

[0045] Hereinafter, the basic structure of the tower-shaped structure concerning this invention is demonstrated concretely based on the ideal embodiment shown in figure.

[0046] exist figure 1 In FIG. 2 , the base of the structure according to the present invention is schematically shown, and the state of supporting the tower-shaped structure 1 such as a column base for wind power generation is shown. A foundation 3 is placed on piles 2 cast underground at the construction site of the tower structure 1 . In this embodiment, this foundation 3 is formed in the shape which has the base part 3a and the pedestal part 3b.

[0047] Such as figure 2 As shown, the tower structure 1 is fastened to the ring-shaped base plate 4 by means of non-adhesive anchors 5 . The non-adhesive anchor 5 is erected on the above-mentioned base plate 4 and the anchor plate 6 to form a way of introducing prestress. These substrates 4 and anchor plates 6 are formed as figure 2 Circular as shown, the...

Abstract

The present invention provides an infrastructure of a tower shaped structure. The infrastructure is provided with column feet which uses the unbonded anchor with introduced prestress for totally fixing for preventing the cracking of concrete at the utmost. For the unbonded anchor (5) which is provided on a substrate (4) and an anchor plate (6) that are concentric with a tower shaped structure (1)and is introduced with prestress, longitudinal ribs (7) parallel with the length direction are provided. The longitudinal ribs (7) are combined with annular ribs (8). Horizontal ribs (9) are configured to a radiation shape with a centre of the cross section of tower shaped structure (1) as a centre with a mode that the horizontal ribs intersect with the unbonded anchor (5) and the longitudinal bars (7). The lower ends of the longitudinal ribs (7) extend to a base part (3a) of the infrastructure (3). The components are executed with rib distribution for manufacturing the concrete (10) to a size that the outer diameter of a base part (3b) can be configured with horizontal ribs (9).

Description

technical field [0001] The present invention relates to a foundation structure of a tower-like structure constructed at a high position in the sky, such as a pillar built on the ground, a tower, a monument, etc., especially a foundation structure using a prestressed unbonded anchor. Background technique [0002] There are various structures such as towers, monuments, and chimneys as tower-like structures built on the ground, and one of them is a windmill prop for wind power generation, that is, a windmill tower. On the top of the tower are installed a generator that generates electricity through the rotation of the windmill with multiple propeller blades (blades), and a windshield that serves as a heavy object such as a rotating mechanism that aligns the direction of the windmill with the direction of the wind. In addition, in order to stably increase the power generation efficiency, it is necessary to receive the wind stably, and it is desirable that the top be located at a...
