Abstract
A telescopic screed includes main section and telescopic section screeds. The main section screed includes a screed frame and a base plate. The telescopic section screeds are arranged on the left side and/or the right side of the main section screed and include a cross slope framework, a cross slope driver, at least two multistage sliding pipes, a telescopic frame, a telescopic driver, a telescopic section frame, a telescopic section base plate and an elevation difference driver. The cross slope framework is pivotally connected with the main section screed to adjust the cross slope. The multistage sliding pipes are used for transversely guiding the telescopic frames to achieve the telescopic ability of the telescopic section screeds. The telescopic section frame is connected with the corresponding telescopic frame to move up and down to adjust the relative height between the telescopic section frame and the telescopic frame.
