Problems solved by technology

[0004] The height of the fan tower is generally high, and the load transmitted to the foundation is relatively large. Therefore, the traditional reinforced concrete foundation has a large volume, a large amount of concrete, and a dense spacing between the steel bars. The concrete is not easy to pour, and the site construction efficiency is low. Improve and innovate its structural system based on the characteristics of the force

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, a wind power tower foundation ring rib beam foundation based on composite structure, the system includes foundation ring (1), studs (2), circular concrete floor (3), H-shaped steel rib beam with variable cross-section ( 6), concrete pillars (7), etc. The lower part of the foundation ring (1) is poured together with the concrete bottom plate (3), and the connection is strengthened by the studs (2) arranged along the ring direction. A cushion layer (4) is arranged under the concrete base plate. The variable-section H-shaped steel rib beam (6) is connected to the concrete bottom plate (3) through studs (2) arranged along the lower flange. The web of the rib beam is provided with longitudinal stiffeners (8), and the end of the beam extends into the concrete pillar (7). The concrete pillar (7) adopts a hollow structure, and removes the ...

Abstract

The invention discloses a wind power tower drum foundation ring ribbed beam type foundation based on a combined structure, and relates to the technical field of onshore wind power generation. The system comprises a foundation ring, a circular concrete floor, a variable-cross-section H-shaped steel rib beam, a hollow concrete pillar, a toggle pin and a square steel shear connector. The foundation ring is connected with a wind power tower drum on the upper part, and a perforation reinforcing steel bar required by a traditional basic ring is removed and replaced with the prefabricated welding toggle pin, so that the basic ring and a foundation concrete form effective connection by utilizing favorable shearing resistance and pulling resistance of the toggle pin, and the construction difficultyin reinforcing steel bar perforating on site is remarkably reduced. The variable-cross-section H-shaped steel rib beam is connected with a foundation slab and the pillar through the shear connector so as to form a combined structure stress system, so that the mechanical characteristics of two materials are fully played, and larger internal force produced by the upper load can be resisted. The foundation system can be applied to a circular bearing platform of a circular spread foundation or a pile foundation, and is high in on-site construction efficiency and material-saving so as to have a good engineering application prospect.

Description

technical field [0001] The invention relates to the technical field of land wind power generation. Background technique [0002] Wind power is a non-polluting, renewable and clean energy. Onshore wind farms have high power generation, stable wind turbine operation, and mature manufacturing technology, and have been widely used in recent years. [0003] The upper steel tower of the wind turbine and the foundation can be connected through prestressed anchor bolts or foundation rings. Among them, the cost of prestressed anchor bolts is relatively high, and the cost of the foundation ring is relatively low. It is necessary to cooperate with perforated steel bars to strengthen the connection with the foundation concrete part to prevent the foundation ring from being damaged by the connection with the concrete under the action of a large upper load. The perforated steel bars are densely arranged and large in number, which causes inconvenience in on-site construction, and the she...
