Embodiment Construction

[0031] Below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation, features and effects of the construction method of the upside-down triangular inclined climbing hanging basket proposed according to the present invention will be described in detail as follows.

[0032] see Figure 1 to Figure 3 , the construction method of the upside-down triangular inclined climbing hanging basket of the present invention, comprises the following steps:

[0033] (1) The concrete strength of the bridge under construction meets the design requirements;

[0034] (2) Install a jack or hoist on the beam surface of the cast box girder 10 whose strength meets the requirements to lift the assembled bottom basket frame 1 and part of the beam of the main truss system 2 to the bottom of the cast box girder 10, and install the tie rod 3 and the anti-retreat anti-shear arm 4, the anti-retreat anti-shear arm 4 is manually installed with the assistance of a ...

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...
