Problems solved by technology

However, the poured concrete and the anchor bolts are bonded together, and when the overturning moment generates a load and the adhesion is severed, cracks are formed in the concrete, and when the allowable stress strength of the concrete is exceeded, the concrete may be destroyed.

Embodiment Construction

[0044] Hereinafter, the basic structure of the tower structure of this invention is demonstrated concretely based on the preferred embodiment shown in figure.

[0045] like figure 1 As shown, in this foundation structure, a tower-shaped structure such as a windmill tower is fixed to the foundation by using the unbonded anchor bolt 1 introducing prestress. The non-adhesive anchor 1 is prestressed and straddled on the base plate 2a and the anchor plate 2b. In the direction intersecting with the longitudinal direction of the unbonded anchor bolt 1, an appropriate number of horizontal steel bars 3 are arranged, and longitudinal steel bars 4 in a direction parallel to the longitudinal direction of the unbonded anchor bolt 1 are arranged. .

[0046] For example, in a wind power generation tower, since the hollow cylinders are stacked, the non-adhesive anchors 1 are arranged at appropriate intervals along the arc of the hollow cylinders. In addition, in figure 1 In the figure, al...

Abstract

The invention provides a basic structure of a tower-shaped works which is the basic structure of the pillar or tower and other tower-shaped works. The basic structure has a totally fixed pillar pin potion which enables the guided pre-stress without the adhesive; the potion inhibits the generation of the cracks for the concrete. A transverse steel bar (3) and annular steel bar (5) are distributed on the crossing direction with the length corresponding to the non-adhesive anchor bolt (1) arranged on the substrate (2a) and the anchor bolt board (2b) and the pre-stress; a vertical steel bar (4) is distributed in the parallel direction of the length. While distributing the steel bar and casting the concrete (6), the invention significantly increases the thickness of the concrete (6) of the crossing direction of the length direction of the non-adhesive anchor bolt (1).

Description

technical field [0001] The present invention relates to a foundation structure, which is a foundation structure of a tower-like structure built up to a high position in the sky, such as a pillar built on the ground, a tower, a monument, etc. The basic structure of anchor bolts. Background technique [0002] As tower-like structures built on the ground, there are various structures such as various towers, monuments, and chimneys, and a windmill tower, which is a pillar of a windmill for wind power generation, is one of them. On the top of the tower, there are multiple propeller blades (blades) supported by horizontal shafts, and weights such as a generator for generating electricity by the rotation of the windmill, and a rotating mechanism for aligning the direction of the windmill with the wind direction are installed. In addition, it is necessary to receive strong wind of a certain intensity in order to stabilize it and improve power generation efficiency, so it is prefera...
