The embedded plate is fixedly connected with the climbing cone through the screw, the screw and the climbing cone are poured in the tower column, and two supporting corbels arranged in parallel at the front and rear are fixed on each embedded plate, and the supporting corbels are all made of steel plates. production;

A connecting through hole is opened on each of the supporting corbels in the horizontal direction, and the front and rear ends of the two steel bars respectively pass through the connecting through holes on the two supporting corbels connected to the same embedded plate and are connected with the same embedded plate. The support corbel is welded and fixed, and the two steel bars are arranged in the horizontal direction;

The left and right ends of the four transverse beams arranged at parallel intervals in the front and rear are respectively supported and arranged on the left and right steel bars corresponding to each other and are welded and fixed with the steel bars on the corresponding sides. On the cross beam, a bridge deck is fixed on the distribution beam, and protective railings are respectively fixed on the front and rear sides of the bridge deck.

The beneficial effects of the utility model are as follows: the device fully considers the narrow space of the inner cavity of the tower, the design is reasonable, the structure is simple, the construction quality is improved, and the construction cost of the offshore bridge tower is saved. The setting of the bridge deck and protective railing improves the operating environment of workers and improves the overall safety and stability of the platform. The operation platform has a fast dismantling speed and can be used in different segments in the tower.

Detailed ways

The present patent will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in the accompanying drawings, the operation platform device of the present invention for construction in a bridge tower includes pre-embedded parts 5 which are pre-buried on the left and right sides of the tower column 1 respectively. Four embedded parts 5, the four embedded parts 5 on the left side of the tower column 1 and the four embedded parts 5 on the right side of the tower column 1 are arranged in one-to-one correspondence with each other;

Each of the pre-embedded parts 5 includes an embedded part plate embedded on the outer wall of the corresponding side of the tower column 1, the embedded part plate is fixedly connected to the climbing cone through a screw rod, and the screw rod and the climbing cone are cast on the tower column. Inside, two supporting corbels 6 are fixed on each embedded plate and are arranged in parallel and spaced apart, and the supporting corbels 6 are all made of steel plates.

A connecting through hole is opened on each of the supporting corbels 6 along the horizontal direction, and the front and rear ends of the two steel bars 7 respectively pass through the connecting through holes on the two supporting corbels 6 on the same embedded plate. And it is welded and fixed with the support corbel 6 . The two reinforcing bars 7 are arranged in the horizontal direction.

The embedded part 5 is poured inside the concrete of the tower column, and is composed of the embedded part plate, the screw rod and the climbing cone connection, so that the embedded part can have a good tensile effect. The climbing cone can precisely locate the embedded plate and the screw, and fix it on the formwork by ordinary bolts before the concrete is poured.

The left and right ends of the four horizontally spaced front and rear beams 2 are respectively supported on the left and right steel bars 7 and the right steel bars corresponding to each other, and are welded and fixed with the steel bars on the corresponding sides.
