Construction method adopting inverted triangular obliquely-crawling hanging basket

Abstract

The invention discloses a construction method adopting an inverted triangular obliquely-crawling hanging basket. The method comprises the following steps: an assembled bottom basket skeleton (1) and part of cross beams of a main truss system (2) are loaded in the bottom surface of a poured box girder (10), and a pull rod (3) and a retaining shearing arm (4) are mounted; a track (6), a basket hanging hook and a traveling system are mounted on a girder surface of the poured box girder (10), the track (6) is mounted, and the traveling system is positioned in the track (6); the triangular main truss system (2) is mounted under the bottom basket skeleton (1); and a template system (7) is mounted and poured; the pull rod (3) and a pivot lifting jack (8) are loosened so as to enable a counterforce wheel (9) to be in contact with the bottom of the poured box girder (10), so that the hanging basket can move forwards along the track (6) to the next construction position. The construction method has the characteristics separated support and bearing systems during construction, simplicity and convenience for assembly, and high traveling stability.

Description

technical field [0001] The invention belongs to the technical field of engineering, and in particular relates to a construction method of an upside-down triangular inclined climbing hanging basket. [0002] Background technique [0003] Cantilever pouring construction is a new type of construction technology developed since it was first used in former West Germany in the 1960s. The hanging basket cantilever pouring construction uses a small amount of construction equipment and avoids a large number of brackets. It can easily build overpasses that span deep valleys, large-flow rivers, and large-traffic volumes. Moreover, the construction is not limited by the span. The larger the span, the higher the economic benefits. , so it has been widely used in long-span box bridges in my country. [0004] Hanging basket is the main equipment for cantilever pouring construction. It is a movable formwork that can walk along the track, and cantilevered on the cantilever beam section tha...

AI Technical Summary

Problems solved by technology

At present, the formal assembly of the general hanging basket is carried out on the 0# block at the top of the bridge pier; the walking system of the hanging basket adopts rolling or sliding, etc., and its power uses hydraulic cylinders or chains, etc., and its structure is complex, difficult to assemble, and walking stability is poor
