Pier and beam asynchronous construction method for hollow thin-wall pier tie beam

The invention discloses a pier and beam asynchronous construction method for a hollow thin-wall pier tie beam. The method comprises the following steps that, i, a chamfer between a pier body and the bottom of the tie beam is constructed when the pier body is constructed to a tie beam section; ii, a pier body form is not detached and the pier body is continuously constructed upwards; iii, a prefabricated plate is set up on the chamfer to serve as a construction platform and a bottom mold; and iv, the tie beam is constructed. Aimed at solving the problems that in the case of existing pier body and tie beam construction steps, a pier body tie beam lower section, a pier body tie beam section and tie beam and a pier body tie beam upper section are sequentially constructed upwards layer by layer, compared with pier body construction, tie beam construction is more complex, and then overall construction period is delayed due to the tie beam construction, the pier and beam asynchronous construction method for the holl
