10. The splicing method of precast beam reinforcing mesh pieces according to claim 7, wherein one side of the turnover support corresponding to the bottom rib platform is inclined downwards, the turnover support is provided with a reinforcing hook which extends out of the inclined assembly surface and is bent upwards to form an L-shaped hook body, in the step S2, the web reinforcing mesh pieces are parallel to the inclined assembly surface of the turnover support through a crane, so that the corresponding bottom rib platform is firstly placed on the inclined assembly surface, and the web reinforcing mesh pieces slide along the inclined assembly surface under the action of gravity and then form a clamping support through the reinforcing hook.
