Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

The utility model discloses a double hoop support structure, which comprises a support column 1, an upper hoop 2, a lower hoop 3 and two connecting and supporting pieces 4;

the upper anchor ear 2 and the lower anchor ear 3 both comprise two

clamping pieces

21 and 31 clamped at two sides of the support column 1, and the ends of the

clamping pieces

21 and 31 of the upper anchor ear 2 and the lower anchor ear 3 in the same direction are respectively locked at the upper part and the lower part of the connecting support piece 4 through bolt groups 5;

the connecting support 4 comprises a connecting plate 41 for locking the clamping member 21 and a supporting plate 42 vertically connected to the upper end of the connecting plate 41, and the supporting plate 42 is used for installing a frame of the cast-in-place box girder; the positions of the upper anchor ear 2 and the lower anchor ear 3 on the connecting plate 41 can be adjusted.
