Problems solved by technology

[0003] The conventional tower is conical, and the inside of the wall is a straight line from the top to the bottom, so the prestressed tunnel can be opened. Due to the structural limitation of the segmented straight tower, the segmented straight tower is not a straight line from top to bottom. , it is not easy to wear prestressed pipes and prestressed tendons, and conventional internal prestressed structures cannot be used, only external prestressed structures can be used

Abstract

The invention discloses a prestressed anchoring conversion structure for tower drum construction and an anchoring method thereof. A tower drum comprises a tower drum foundation and a concrete tower drum arranged on the tower drum foundation, and the prestressed anchoring conversion structure comprises an adapter ring, a prestressed cable and a pre-embedded screw, wherein the adapter ring is arranged in the tower drum foundation and is not less than 150 mm in thickness, and a first matching hole and a second matching hole which penetrate through the adapter ring in the thickness direction are formed in the adapter ring; the prestressed cable is connected with the adapter ring through the first matching hole; and the pre-embedded screw is connected with the adapter ring through the second matching hole, and the pre-embedded screw is located at the bottom of the adapter ring. According to the prestressed anchoring conversion structure for tower drum construction, an external prestress scheme can be adopted, the prestressed cable is tensioned from the top of the tower drum to the tower foundation, and the tower drum is more stable.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a prestressed anchor conversion structure and an anchor method for tower construction. Background technique [0002] In related technologies, as the power generation efficiency of the fan increases, the length of the blade becomes longer and longer, and the height and cross-sectional size of the matching fan tower also continue to increase. Due to high cost and difficult transportation, steel structure towers are difficult to meet the construction requirements of large cross-section and high towers. Prefabricated concrete towers enable the economical construction of large wind turbines. During the construction of concrete towers, individual towers are hoisted sequentially from bottom to top, and finally a complete concrete tower is built. [0003] The conventional tower is conical, and the inside of the wall is a straight line from the top to the bottom, so the pr...
