The invention relates to the technical field of bridge deck construction, and discloses a prefabricated assembly type steel-concrete composite beam guardrail bridge deck structure, a bridge deck is composed of a prefabricated bottom plate, two guardrails, a pouring layer and an I-shaped steel main beam, a first extension groove is formed in the upper surface of the prefabricated bottom plate, second extension grooves communicating with the first extension groove are formed in the surfaces of the left side and the right side of the prefabricated bottom plate correspondingly, contact grooves are formed in the surfaces of the sides, facing the second extension grooves, of the guardrail vertical plates, built-in grooves are formed in the inner wall of the left side of the first extension groove, and self-locking mechanisms are arranged in the built-in grooves. According to the prefabricated assembly type steel-concrete composite beam guardrail bridge deck structure, the guardrails are produced in a prefabricated mode, the standard installation operation procedure of the guardrails is easily achieved by a production factory, the high quality of guardrail production is achieved, the risks of concrete cracking and internal steel bar corrosion in the long-time use process of the guardrails are prevented, and the long-time use effect of the guardrails is guaranteed.
本发明涉及桥面施工技术领域，且公开了一种预制装配式钢混组合梁护栏桥面板结构，桥面板由预制底板、两个护栏、浇筑层以及工字钢主梁组成，预制底板的上表面开设有第一延伸槽，预制底板的左右两侧表面均开设有与第一延伸槽相通的第二延伸槽，护栏竖板面向第二延伸槽的一侧表面上开设有接触槽，第一延伸槽的左侧内壁上开设有内置槽，内置槽内设置有自锁机构。该预制装配式钢混组合梁护栏桥面板结构，通过将护栏以预制的方式进行生产，护栏由生产工厂易于实现标准化安装作业工序，实现护栏生产高质量，防止了护栏在长时间使用过程中出现混凝土开裂以及内部钢筋锈蚀的风险，保障了护栏在长时间使用效果。
