Segmental prefabricated composite section spine girder bridge structure system
The invention provides a segmental prefabricated composite-section spine girder bridge structure system. The spine girder bridge structure system is characterized in that the section of a spine girderis mainly formed by compounding a core longitudinal beam and a rear-mounted cantilever arm; the two parts can adopt a precast concrete member assembled by sections at the same time, or can be partially precast and assembled and partially cast in place; on the basis of the two parts, the structural system further comprises various corresponding longitudinal and transverse joints at the same time.The construction sequence of the structure system is as follows, firstly, core longitudinal beam construction within a span is completed, and then the cantilever arm is mounted, so the core longitudinal beam is constructed step by step after the core longitudinal beam is formed. According to the structural system, the construction speed can be increased, the structural economy is improved, the design and construction key technology of the segmental prefabricated assembled concrete bridge is improved, and the development of the segmental beam prefabricated assembling technology is promoted.
本发明提供了一种节段预制复合截面脊骨梁桥结构体系，所述脊骨梁截面主要由核心纵梁和后装挑臂两部分复合组成；上述两部分可同时采用节段拼装的预制混凝土构件，或部分预制拼装、部分现浇；所述结构体系在上述两部分基础上，还同时包含相应的各类纵横向接缝；所述结构体系的施工顺序为：首先完成一跨内的核心纵梁施工，后装挑臂则待该部分核心纵梁成型后再逐步施工。本发明的结构体系可加快施工速度，增加结构经济性，提升节段预制拼装混凝土桥梁的设计和施工关键技术，推动节段梁预制拼装技术的发展。
