Abstract

The invention belongs to the technical field of steel structure bridge construction, and discloses a method for installing a double-layer steel box girder bridge and a combined bracket for installation; the combined bracket for installing a double-layer steel box girder bridge includes: a first column group, a first beam , the second column group, the second beam and the base plate; the first column group includes: a plurality of first columns, and the first beam is fixed on the plurality of first columns to form a lower support; the first column group The second column group includes: a plurality of second columns, and the second beam is fixed on the plurality of second columns to form an upper bracket; the plurality of first columns and the plurality of second columns are fixed on the plurality of second columns. The base plate; wherein, the height of the first column is lower than the height of the second column. The installation method of the double-layer steel box girder bridge and the combined support for installation provided by the application can realize efficient and synchronous installation of the double-layer steel box girder bridge.

Description

technical field [0001] The invention relates to the technical field of steel structure bridge construction, in particular to a double-layer steel box girder bridge installation method and a combined bracket for installation. Background technique [0002] Double-layer bridges can significantly improve urban traffic capacity and reduce land occupation, so they are widely used in municipal viaducts. Usually, the design width of a single bridge is generally 12 to 16 meters, with 3 to 4 lanes. Due to the influence of the complex environment of the municipal viaduct, most of them are installed by the bracket method, and each layer of construction is to build a layer of brackets; Large, requires a large amount of support materials, covers a large area, and requires framed construction, high cost and long cycle. At the same time, due to the limited operating space, construction machinery cannot be used, etc., resulting in complex construction process, long period, high cost, and hi...
