Detailed Description
The patent is described in detail below with reference to the figures and the specific embodiments.
The utility model discloses an operation platform device for construction in bridge tower, as shown in the attached drawing, including pre-buried in the built-in fitting 5 of the left and right sides of king-post 1 respectively, the interval pre-buried in four built-in fittings 5 around each side of king-post 1 respectively, four built-in fittings 5 on the left side of king-post 1 and four built-in fittings 5 on the right side of king-post 1 are set up with one another in a left-right one-to-one correspondence;
each embedded part 5 including bury the embedded part board on the corresponding side outer wall of column 1 underground, the embedded part board pass through the screw rod with climb the awl and fixedly link to each other, the screw rod with climb the awl and pour in the column, be fixed with two support brackets 6 that parallel interval set up back and forth on each embedded part board, support bracket 6 is made by the steel sheet.
Each support bracket 6 on open along the horizontal direction and have a connect the through-hole, two reinforcing bar 7 front and back both ends pass the connect the through-hole on two support brackets 6 on the same piece board of burying respectively and with support bracket 6 welded fastening. The two steel bars 7 are arranged along the horizontal direction.
The embedded part 5 is poured inside the concrete of the tower column and is formed by connecting an embedded part plate, a screw rod and a climbing cone, so that the embedded part has a good tensile effect. The climbing cone can accurately position the embedded plate and the screw rod, and is fixed on the template through a common bolt before concrete pouring.
