Hanging method of special-shaped reinforced concrete prefabricated column
The invention discloses a hanging method of a special-shaped reinforced concrete prefabricated column. The method comprises the steps that (1) a hanging starting point position on a special-shaped column is computed; (2) a turning hanging point position on the special-shaped column is computed; (3) sleeve pipes are buried at the hanging starting point and the turning hanging point in advance; (4) long-rod screws penetrate into the pre-buried sleeve pipes of the turning hanging point respectively; (5) special-shaped column demoulding and turning are carried out; (6) preparing before hanging of the special-shaped column is carried out; (7) hanging of the special-shaped column is carried out; (8) a special-shaped column foot is stabilized and is inserted into a cup-shaped foundation; (9) special-shaped column aligning is carried out; (10) a crowbar is used for prying a wedge, or a hammer is used for striking the wedge, so that the center line of the column body is aligned with the center line of the cup bottom; (11) crane unhooking is carried out, and the special-shaped column is placed to the cup-shaped foundation bottom; (12) the wedge on the periphery is tightly stricken; (13) special-shaped column perpendicularity correction is carried out; and (14) grouting is carried out immediately after correction is carried out. During component prefabricating, a hanging hole is reserved, and the shortcomings that hanging point sliding and component corner damage which can happen easily through a conventional binding method are overcome.
