Abstract

The invention relates to the field of continuous girder construction, in particular to a hanging basket device for closure construction of continuous box girders, which solves the problem that the hanging basket device cannot return to the outside of a railway clearance to be detached during closure concrete construction above a railway. The hanging basket device comprises a head piece, a road wheel, a steel rail, an external mold truss, an external template, a bottom mold crossbeam, a bottom mold stringer, a bottom mold square timber and a bottom template; an external mold bearing crossbeam is arranged under the external mold truss, and is hung at two ends of the head piece through an external mold jack and an external mold suspender; two ends of the bottom mold crossbeam are connected with two ends of the top piece through a bottom mold jack and a bottom mold suspender; a bottom mold operating platform is suspended under the bottom mold crossbeam; an extended vertical member is connected under the external mold truss and is provided with upper and lower limiting U-bars and a platform U-bar; and an external mold bottom operating platform is erected on the platform U-bar. The hanging basket device has the advantages of simple structure, reasonable design, simple and convenient operation, good using effect, improvement of the returning speed and time and labor saving.

Description

technical field [0001] The patent of the present invention relates to the field of continuous beam construction, specifically a hanging basket device especially suitable for the construction of the closing section of the continuous box girder with limited construction space above the existing line. Background technique [0002] Continuous box girder is one of the important ways to span existing roads and canals. It has the characteristics of wide application and simple and easy-to-understand construction technology. Hanging basket is a kind of equipment used for concrete bridge cantilever cast-in-place. The removal of hanging basket usually requires On-site overall demolition, but when crossing the existing railway, the distance between the design elevation of the bottom of the box girder and the catenary line and beam of the existing line is limited, and the removal of the hanging basket must be returned to the boundary of the existing line for removal. The hanging basket co...
