Positioning method for pre-embedded steel bars in assembled sleeves of building element

The invention discloses a positioning method for pre-embedded steel bars in assembled sleeves of a building element. According to the method, firstly a steel bar positioning tool is made, a steel plate is provided with through holes matched with the pre-embedded steel bars and vibrating holes, and the sleeves are welded on the through holes respectively; preliminary positioning is performed on thepre-embedded steel bars to determine the planar positioning dimensions of the pre-embedded steel bars; the sleeves are enabled to sleeve the pre-embedded steel bars, and the steel plate is fixed; concrete pouring is carried out on the cast-in-situ structure, the position and perpendicularity of the pre-embedded steel bars are re-checked after the pouring and before the initial setting of the concrete so as to complete the positioning for the pre-embedded steel bars. The positioning method realizes accurate positioning for the pre-embedded steel bars through the self-made tool, ensures the element to be hoisted in pla
