Problems solved by technology

[0002] At present, most of the large-scale towers in the field of wind power generation are made of steel plates rolled into cylindrical towers. In order to resist the top-to-bottom moment of the towering structure, a thick steel plate is often required, resulting in a large amount of steel consumption and high cost. The investment is high; secondly, the cylinder that makes the tower column is integral, with a large diameter, generally 3 to 5 meters, and transportation is difficult at this time, and the transportation cost is high; in addition, the tower column has not been prestressed. When encountering strong winds, the top of the tower column is prone to greater deflection and shaking under the action of the wind; moreover, the large-scale tower column also has a reinforced concrete structure, which is quite heavy and difficult to construct and pour. , the construction period is long, and industrialized production cannot be realized, so the investment and management costs are quite high

Embodiment Construction

[0028] Such as Figure 12 As shown, the steel plate is pre-processed into a steel plate with a plurality of vertical corrugations, that is, a corrugated steel plate. Another example Figure 13a , 13b , 13c, the corrugated steel plate can have continuous sinusoidal corrugations, or discontinuous special-shaped corrugations, such as semicircular arch, low arch, box type, etc. Another example Figure 1-11 As shown, the corrugated steel plate that meets the standard will be processed into two-layer buckle assembly inside and outside, and the contact part of the two-layer corrugated steel plate will be connected with high-strength corrosion-resistant bolts 5, which are high-strength corrosion-resistant hot-dip galvanized bolts, and the amount of hot-dip galvanizing More than 350g / m 2 , the strength grade is greater than or equal to 8.8. According to actual needs, the contact part of the two-layer corrugated steel plate can be connected by one or more corrosion-resistant bolts 5...

Abstract

Disclosed is a pre-stressed steel-concrete composite-type pylon structure formed of assembled single structural member bodies. The single structural member bodies are formed by symmetrically fastening an inner layer of corrugated steel plate (1) and an outer layer of corrugated steel plate (2), and the two, inner and outer, layers of corrugated steel plate (1, 2) form several hollow cylinders, in which a steel reinforcement bar (3) is provided and concrete (4) is filled. The pylon can be assembled from multiple pieces or multiple sections, can be completely pre-fabricated at a factory or the corrugated steel plate can be pre-fabricated after transport on-site; construction is convenient and simple, and the construction cycle is short, reducing the amount of steel used in the pylon and greatly saving on costs.

Description

technical field [0001] The invention relates to a tower column structure, in particular to a prestressed steel-concrete combined tower column structure in the fields of wind power generation and construction. Background technique [0002] At present, most of the large-scale towers in the field of wind power generation are made of steel plates rolled into cylindrical towers. In order to resist the top-to-bottom moment of the towering structure, a thick steel plate is often required, resulting in a large amount of steel consumption and high cost. The investment is high; secondly, the cylinder that makes the tower column is integral, with a large diameter, generally 3 to 5 meters, and transportation is difficult at this time, and the transportation cost is high; in addition, the tower column has not been prestressed. When encountering strong winds, the top of the tower column is prone to greater deflection and shaking under the action of the wind; moreover, the large-scale towe...
