Detailed ways

In order to further explain the technical solutions of the present utility model, the present utility model will be described in detail below through specific embodiments.

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

The upper hoop 2 and the lower hoop 3 both include two clamping pieces 21 and 31 that are clamped on both sides of the support column 1 . They are respectively locked on the upper and lower parts of the connecting support 4 through the bolt group 5;

The connecting support 4 includes a connecting plate 41 for locking the clamping member 21, and a support plate 42 vertically connected to the upper end of the connecting plate 41. The support plate 42 is used to install the frame of the cast-in-place box girder; the upper hoop 2, the lower The position of the hoop 3 on the connecting plate 41 is adjustable.

Referring to Figures 1 to 5, specific embodiments of the present invention are shown.

The above hoop 2 is taken as an example, the above-mentioned clamping member 21 includes a circular arc piece 211 hugged on the side surface of the support column 1, and a connecting piece 212 integrally connected to both ends of the circular arc piece 211; the connecting piece 212 is provided with a number of supply bolts The first mounting hole 213 for the assembly of group 5. In this embodiment, the above-mentioned first mounting holes 213 are distributed on the connecting piece 212 in a matrix along the up-down and left-right directions, which facilitates adjustment of the assembly position and quantity of the bolt group 5 and improves the firmness of the overall structure.
