Method for processing, manufacturing and constructing prefabricated small box girder hanging bracket

Abstract

The invention relates to a method for processing, manufacturing and constructing a prefabricated small box girder hanging bracket, which comprises a small box girder hanging bracket structure design and processing and manufacturing method: the small box girder hanging bracket structure is formed by forming a group by two hanging brackets, each hanging bracket is provided with eight waist-shaped hoisting holes, and eight preformed holes are reserved in corresponding positions of a small box girder; the hanging bracket is connected with the small box girder through a high-strength hanging rod/finish rolling deformed steel bar; two lifting lugs are arranged on each lifting frame and are connected through lifting pin rods, and lifting operation can be carried out through shackles and lifting equipment; a small box girder mounting and small box girder hanging bracket using method comprises the steps that small box girders are transferred and loaded in a prefabricated part factory through the small box girder hanging bracket; the small box girder is hoisted and installed on the top of the bent cap through the small box girder hoisting frame after being transported to an installation site, and the small box girder hoisting frame is dismantled after the small box girder is hoisted. The problems that the small box girder is difficult to install in a complex environment and the small box girder structure is uneven in stress under a special hoisting working condition are solved; and by using the small box girder hanging bracket, the construction safety is greatly improved, and the construction cost is saved.

Description

technical field [0001] The invention relates to a prefabricated small box girder hanger, in particular to a prefabricated small box girder hanger for prefabricated and assembled urban viaducts / highways, and a processing and construction method thereof. Background technique [0002] With the acceleration of the pace of social development, prefabricated assembly components have become the mainstream of modern construction, and the frequency of use of prefabricated components in urban viaducts and expressways is becoming more and more common. [0003] Considering the construction efficiency and cost input and the convenience of construction in urban viaducts and expressways, in order to improve the work efficiency of prefabricated small box girders in the prefabricated component factory for shifting and lifting and installation at the construction site, the small box girders and other components are prefabricated during the prefabrication process. Corresponding lifting points a...
