Construction method of running rail-free triangular hanging basket

Abstract

The invention discloses a traveling-rail-free type triangular hanging basket traveling construction method. The method includes the steps: firstly, arranging front supporting seats and rear supporting seats on the lower side of a triangular hanging basket main truss longitudinal beam, arranging forward pressing wheels at the top ends of the front supporting seats, arranging reverse pressing wheels at the top ends of the rear supporting seats, enabling the reverse pressing wheels to press the main truss longitudinal beam, and enabling the forward pressing wheels to butt against the lower side of the main truss longitudinal beam; secondly, uplifting the front end of the main truss longitudinal beam; thirdly, moving the front supporting seats forwards and then replacing the front end of the main truss longitudinal beam on the front supporting seats; fourthly, uplifting the rear end of the main truss longitudinal beam; fifthly, moving the rear supporting seats forwards; sixthly, connecting the rear supporting seats with embedded parts of a continuous beam body; seventhly, transferring stress of a bottom form assembly from a rear hanging system to outer slide beams; eighthly, moving triangular hanging baskets forwards and then connecting back anchoring positions of the triangular hanging baskets with the embedded parts of a connecting beam body; and ninthly, connectedly fastening the front supporting seats with the triangular hanging basket main truss longitudinal beam. The triangular hanging basket traveling construction method is capable of achieving rapid and safe traveling of the triangular hanging baskets without specially arranging a traveling rail.

Description

Technical field [0001] The invention relates to a traveling construction method of a bridge cantilever pouring a hanging basket, in particular to a traveling construction technology of a triangular hanging basket without a traveling rail. Background technique [0002] At present, with the gradual maturity of the construction technology of large-span cantilever pouring of continuous beams, the construction technology of the supporting cradle itself is also continuously improved. Now the commonly used cradle forms in China mainly include: triangle cradle, diamond cradle, truss cradle Wait. [0003] At present, the cantilever pouring cradle mostly uses the cradle without balance weight, and the problem of forward overturning must be solved when the cradle is walking. At present, the unbalanced weight hanging basket walking system is composed of steel sleepers, walking tracks, walking track (steel sleepers) anchoring devices, reverse buckle wheels and driving devices. In order to avo...

AI Technical Summary

Problems solved by technology

It is mainly used for truss-type hanging baskets. For diamond-shaped and triangular hanging baskets, due to the large number of upper rods, it is impossible to walk after installing positive buckle wheels on the upper part.

The main truss of the truss-type hanging basket is relatively close to the beam surface, and the construction work surface of the beam surface is limited. The truss-type hanging basket itself has this defect, which causes this kind of hanging basket to have certain limitations on the construction of the cantilever beam, and the lower part of the hanging basket passes through The gasket supports the weight of the hanging basket, and the friction force is large when the hanging basket is walking, and the gasket is easy to slide, so there are certain unsafe factors

The variable direction hanging basket wheel travel technology, its system includes two front travel devices composed of positive pressure wheels, two rear travel devices composed of reverse pressure wheels, two I-shaped steel rails and a travel device composed of drive motors. Power device, its technology is relatively advanced, but it can not break away from the shackles of the running track, and the operability needs to be further improved
