Abstract

The invention provides a non-falling dynamic height-adjusting support for steel plate composite girder bridge deck construction and a construction method, including a linkage working lower platform, the bottom of the scissor bar lifting assembly is arranged on the linkage working lower platform; A linkage work upper platform is installed on the top; a telescopic cylinder is installed vertically on the linkage work upper platform, a gear box is installed on the top of the telescopic cylinder, and a screw that penetrates the telescopic cylinder and the gear box at the top is installed in the telescopic cylinder. The top is provided with a template pedestal; a motor is installed on the gear box, the rotation of the motor drives the driven gear to rotate with the vertical axis as the rotation axis, and the driven gear rotates with the vertical axis as the rotation axis to drive the screw to rise and fall vertically. The bracket of the present invention can complete the initial elevation adjustment through the scissor-type electric lifting linkage platform, and can realize the precise elevation adjustment through the dynamic and precise adjustment of the screw lifting and lowering by the motor. The two elevation adjustment modes can accurately complete the template elevation adjustment and realize dynamic adjustment. .

Description

technical field

[0001] The invention belongs to the field of roads and bridges, and relates to the construction of steel plate composite girder bridge decks, in particular to a non-floor dynamic height-adjusting bracket and a construction method for the construction of steel plate composite girder bridge decks. Background technique

[0002] The steel-concrete composite structure makes full use of the respective material properties of steel and concrete, and has the advantages of light weight, high bearing capacity, high rigidity, good seismic performance and dynamic performance, small section size of components, and fast and convenient construction. Over the years, it has been fully applied in bridge engineering, especially in municipal bridges.

[0003] The construction of steel plate composite beams is usually by assembling prefabricated steel beam segments on site. The prefabricated concrete slab only needs to pour concrete at the reserved slot, which reduces the workloa...
