Quick mounting method for prefabricated segmental box girder
The invention provides a quick mounting method for a prefabricated segmental box girder. The quick mounting method comprises the following steps: step 1) hoisting a T-shaped structure; (2) temporary closure of the T-structure closure section is conducted through a temporary support; and (3) after temporary closure, hole passing and closure construction of the bridge girder erection machine are carried out, and next T-shaped structure hoisting is carried out after the bridge girder erection machine passes through a hole. The prefabricated closure section is suspended on the adjacent T-shaped structure box girder through the closure framework (temporary support), so that the prefabricated closure section can be separated from the bridge girder erection machine, the bridge girder erection machine can pass through a hole and hoist the next T-shaped structure box girder after temporary closure, and the T-shaped structure assembly efficiency is improved. The T-shaped structure cantilever ends on the two sides of the closure section are firmly connected through the section steel beam of the temporary suspension beam of the closure section, and the position changes of the closure section and the T-shaped structure cantilever ends caused by T-shaped structure vibration caused by hole passing of the bridge girder erection machine are reduced. The positioning support fixes the beam at the end of the T-shaped structure through the parallel connection and the inclined strut, it is guaranteed that the position of the beam in the bridge direction and the position of the beam in the transverse bridge direction are stable, and the temporary closure purpose is achieved.
本发明提供了一种预制节段箱梁快速安装方法，包括以下步骤：步骤1）T构吊装；步骤2）通过临时支架进行T构合龙段的临时合龙；步骤3）临时合龙后，进行架桥机过孔及合龙施工，架桥机过孔后进行下一个T构吊装。本发明通过合龙骨架（临时支架）使预制合龙段悬挂在相临的T构箱梁上，使预制合龙段可以脱离架桥机，从而在临时合龙后可以使架桥机过孔，吊装下一个T构箱梁，提高T构拼装效率。通过合龙段临时悬挂梁的型钢梁使合龙段两侧的T构悬臂端连接牢固，减少在架桥机过孔导致的T构震动使合龙段、T构悬臂端的位置变化。定位支架通过平联和斜撑固定T构端部的梁，保证梁的顺桥向位置和横桥向位置稳定，达到临时合龙的目的。
