Novel wind power generation precast concrete tower component seaming structure and method

Abstract

The invention relates to a novel wind power generation precast concrete tower component seaming structure and method. The structure is characterized by at least comprising a longitudinal seam (1), a transverse seam (2), anchoring steel plates (3), high-strength bolts (4), sleeves (5), fixing bolts (6), fixing nuts (7) and waterproof glue (8), the longitudinal seam (1) and the transverse seam (2) are arranged between wind power generation precast reinforced concrete tower components, the precast reinforced concrete tower components are horizontally provided with the anchoring steel plates (3) extending towards the longitudinal seam (1) respectively, the anchoring steel plates (3) are integrally connected with one end of each high-strength bolt (4), the other end of each high-strength bolt (4) is connected with the corresponding sleeve (5) in a threaded manner, the sleeves (5) on two sides are fixedly connected with the fixing nuts (7) through the fixing bolts (6), the upper and lower precast reinforced concrete tower components are respectively provided with a positioning key groove (9) and a positioning key (10) extending towards the transverse seam (2), and each positioning key groove (9) is bonded with the corresponding positioning key (10) through epoxy resin (11). By the aid of the structure, assembly of the precast components can be accelerated, time is saved, the construction method is simple, and construction is facilitated.

Description

technical field [0001] The invention belongs to the field of wind power generation towers, and is a novel wind power generation prefabricated concrete tower member joint structure. Background technique [0002] The global energy shortage and severe environmental and climate problems have prompted countries to pay more and more attention to the development and utilization of renewable energy such as wind energy, solar energy, and biomass energy. Wind power research started early and the technology is mature, and it has become a reusable way of renewable energy utilization. Especially in recent years, the installed capacity of wind power has achieved rapid growth. my country's wind energy is rich, of which 253 million kilowatts at a height of 10 m on land, which can be doubled at a height of 50 m; 750 million kilowatts at a height of 10 m offshore, and about 1.5 billion kilowatts at a height of 50 m. As of 2010, my country's wind power generation reached 44.73 million kilowat...

Problems solved by technology

[0004] Due to the limitations of steel tower material properties and cost, high concrete towers are inevitable. The construction period of cast-in-place concrete towers is long, and it is difficult to meet the rapid construction requirements of wind farms. Prefabricated concrete towers came into being.
