Zhangjiakou No. 1 15 MW solar thermal power station tower solar thermal center tower steel structure project

Construction unit:

Zhang Bei Huaqiang Zhaoyang Energy Co., LTD

Project address:

Zhangbei County, Zhangjiakou City

Total building area:

About 150 meters

Project overview:

Tower steel structure project of 15 MW solar thermal power station in Zhangjiakou No. 1, with a diameter of 23 meters and a total height of 148 meters, the center is composed of 6 box columns of 400mm*400mm, and the outer ring is composed of 8 pipe columns of 1000mm*1000mm. The tubular string is tilted inward by 18.5 degrees, forming a pyramidal shape. The central tower is equipped with a sightseeing elevator. Finally, the tower becomes a steel structure project integrating sightseeing and power generation. The steel structure outer ring column is mainly vertical bearing and lateral force resistance structure, including column, inclined beam and inclined brace. The outer ring column has a total of 8 columns, and the inclined brace is inclined to the steel pipe column, using 450mm×14mm steel pipe. The connection between the inclined brace and the steel pipe column adopts the hinged connection form, 8 for each layer; All on-site joints are fully welded and the weld grade is level 1. By H - beam cantilever and pipe string diagonal brace for tying. Ensure that device modules are installed. The steel selected in this project according to the use of the central tower function. All steel columns, beams and struts are Q345C low alloy structural steel; Low hydrogen electrode is used for welding. The outer part of the component was sprayed with zinc arc spray, and the thickness of zinc layer was 80μm.
