Abstract

The embodiment of the invention discloses a construction method and system for dry connection installation of a segmented bent cap. The segmented bent cap dry-connection installation system comprisesat least two stand columns, a bent cap main section, two bent cap cantilever sections, two tensioning devices and an epoxy resin adhesive layer, wherein the bent cap main section is connected to the top ends of the at least two stand columns; the two bent cap cantilever sections are connected to the two sides of the bent cap main section respectively; the two tensioning devices are respectively connected between the two bent cap cantilever sections and the bent cap main section; and the epoxy resin adhesive layer is clamped between the bent cap main section and the bent cap cantilever sections. The embodiment of the invention effectively solves the problem that the segmented prefabricated bent cap is difficult to position and match in the splicing construction process.

Description

technical field [0001] The invention relates to the technical field of road and bridge construction, in particular to a segmented cover beam dry joint installation system and a bridge assembly construction method. Background technique [0002] With the rapid development of our country's economy, our country's bridge construction has also developed rapidly. In the process of bridge construction, the prefabricated assembly construction technology can significantly shorten the construction period and reduce the construction time. At the same time, it has the advantages of high construction quality, low safety risk and environmental protection. Therefore, prefabricated assembly construction technology has been widely used in municipal bridge construction; however, in the actual construction process, due to the limitation of transportation conditions and hoisting weight, more prefabricated cap beams need to be prefabricated in sections and assembled on site construction. [000...
