The invention discloses a quick mounting construction method for a hanging frame system used for a low jacking mould frame system. The quick mounting construction method comprises the following steps: determining dimension of each small barrel of a structured body core barrel, determining a detail dimension of an integral hanging frame beam according to the dimension of each small barrel, and processing a hanging frame beam component required by a hanging frame; after a beret piece platform of a to-be-jacked mould system is mounted, assembling the hanging frame beam component below the beret piece platform to complete assembling of the integral hanging frame beam; arranging a power lifting device on the beret piece platform; after the integral hanging frame beam is lifted, mounting a first step of the hanging frame below the integral hanging frame beam; lifting the integral hanging frame beam to a position at a preset height from the ground, thereby completing mounting of a second step of the hanging frame, and continuously mounting the rest of the hanging frame according to the same method; lifting the integral hanging frame beam to a beret piece bottom chord, and connecting and fixing the integral hanging frame beam to the beret piece platform by utilizing a connector onto the integral hanging frame beam. According to the method disclosed by the invention, mounting time of the hanging frame system is shortened, and construction risks are reduced.
