The application discloses a concrete dome formwork construction method, which comprises a steel
pipe, a first suspension rod, a second suspension rod, a third suspension rod, a first inner inclined rod, a second inner inclined rod and a pull rod. The both ends of the steel
pipe are respectively provided with a hole ear plate, the hole ear plate is provided with a sleeve ring, the steel
pipe is provided with a limiting clamp, and the limiting clamp is provided with a threaded sleeve. The threaded sleeve at the lower part of the steel pipe is screwed, the sleeve ring is gradually jacked up, the lower end position of the first inner inclined rod is lifted, the upper end of the first inner inclined rod jacks up the second suspension rod to make the third suspension rod rise, after being jacked up to the specified position, the threaded sleeve is stopped from being screwed; the included angle between the first suspension rod and the first inner inclined rod becomes smaller, thereby driving the pull rod, promoting the first suspension rod to rotate around the
hinge point thereof, and enabling the whole structure to be expanded and lifted. The whole structure of the application is exquisite, light, efficient, easy to install and disassemble, and compared with a large net rack
structure support system, is more light and convenient to hoist, can be assembled on the ground or a platform and then hoisted, jacked up and positioned, and is more convenient to construct.
