Abstract

The invention discloses a mounting method for a bridge closure segment wavy steel web. A circular hole is formed in the fixing end of the wavy steel web, a circular hole of the free end of the wavy steel web is subjected to transverse broaching to form a long-strip-shaped open hole, and finally the wavy steel web is mounted. Firstly, the mounting angle of a bridge closure segment is well adjusted,then welding is conducted after a nut corresponding to a bolt of the fixing end is tightened up in a constant temperature field, and then welding is conducted after a nut corresponding to a bolt of the free end is tightened up in a closure environment. The form of circular hole forming in the free end of a traditional closure segment wavy steel web is adjusted to be a long-hole form so as to adapt to the condition that the hole positions are hard to align at due to uncertainty of the length of the closure segment, the hole forming mode is simple, the cost is low, on-site mounting is convenient, normal construction is not affected, the adjustable quantity is large, the adaptability is high, and accurate mounting of the closure segment wavy steel web is achieved.

Description

technical field [0001] The invention relates to the construction field of bridge closure sections, in particular to a method for installing corrugated steel webs in bridge closure sections. Background technique [0002] For cantilever poured concrete continuous girder bridges, when the construction reaches the maximum cantilever state, it is necessary to complete the bridge through the construction of the closing section. However, for the continuous box girder bridge with corrugated steel webs, due to the construction requirements of corrugated steel webs in the Helong section, the corrugated steel webs need to be manufactured in the factory, and the steel webs must be installed on site. Whether the corrugated steel web of the closing section can be installed smoothly is related to the processing error of the corrugated steel web, especially the corrugated steel web that needs to be connected by bolts. It is difficult to align the bolt holes of the corrugated steel web; The...
