Document Type and Number:
WIPO Patent Application WO/2023/093115
Kind Code:
A1
Abstract:
A connection structure for one pile and one column in a top-down construction method. The connection structure comprises a steel pipe column casing (1), and a steel reinforced concrete column (2) arranged at an upper end of the steel pipe column casing (1), wherein a connection assembly (3) is arranged between the two, and the connection assembly (3) comprises a first connection plate (31) fixed in the steel pipe column casing (1), and a second connection plate (32) fixed on the steel reinforced concrete column (2). A method for constructing one pile and one column by using a top-down construction method. The method comprises: S1, measuring the coordinates of a constructed steel pipe column casing (1); S2, reserving a post-cast strip space of at least 300 centimeters in the steel pipe column casing (1); S3, hoisting a steel reinforced concrete column (2) and inserting a first connection plate (31) into the steel pipe column casing (1), then rechecking the position of the steel reinforced concrete column (2) on site and correcting same according to a position on a drawing, and appropriately adjusting the position of the steel reinforced concrete column (2) according to a deviation situation; S4, mounting two semicircular plates (33) at a casing opening of the steel pipe column casing (1); and S5, pouring concrete into the post-cast strip space reserved in the steel pipe column casing (1). The connection structure for one pile and one column in a top-down construction method, and the construction method have the effect of improving the structural strength at a connection joint of one pile and one column.
