The invention discloses a technology for hoisting non-penetrated deck plates with upright posts in place. The technology comprises the following steps of (1) measuring a horizontal baseline of a closing position of an upper layer of deck plate and a girder position of the deck plate at the butted part; (2) connecting a plurality of first guide plates at the bottom of the upper layer of deck plate and controlling the positions of the upper layer of deck plate when in place in X and Y directions; (3) arranging a plurality of second guide plates at the top end of each upright post of a lower layer of deck plate to adjust the position in a Z direction; (4) arranging a plurality of filling plates at the top end of each upright post of the upper layer of deck plate; (5) after assembly is completed, connecting the upright posts of the upper layer of deck plate and the upright posts of the lower layer of deck plate into a whole; (6) carrying out dimension positioning detection and appearance inspection; and (7) after assembly inspection is qualified, carrying out all fusion-through welding on all nodes and removing a crane. The non-penetrated deck plates with the upright posts can be accurately hoisted in place in the X and Y directions, and the problem that the non-penetrated deck plates with the upright posts are accurately hoisted in place is solved; furthermore, the deck plates can be automatically hoisted in place, so that the hoisting efficiency and the welding quality are improved.
