预制组合梁节段连接结构及其应用
摘要：
本发明涉及预制组合梁节段连接结构及其应用，连接结构包括：由一块大拼接板及两块小拼接板组成的拼接板组，由至少两套螺栓副组成的螺栓组，每套螺栓副包括一带螺纹的螺杆、连接在小拼接板表面的固定螺母、连接在大拼接板表面的紧固螺母以及连接在带螺纹的螺杆自由端的锚固螺母，预制组合梁节段连接结构可以应用在组合梁的连接中，包括混凝土预制板、混凝土后浇段及该连接结构。与现有技术相比，本发明降低了制作安装成本，加快了工程的施工速度，降低了工程的总造价，提高了结构的耐久性。
摘要（英）：

The invention relates to a prefabricated composite beam segment connecting structure and application thereof. The connecting structure comprises a splice plate set composed of a large splice plate and two small splice plates and a bolt group composed of at least two sets of bolt pairs. Each bolt pair comprises a threaded rod with a thread, a retaining nut for connecting the surfaces of the small splice plates, a fastening nut for connecting the surfaces of the large splice plates and an anchoring nut connected to the free end of the threaded rod with the thread. The prefabricated composite beam segment connecting structure can be applied to connection of a composite beam, and the composite beam comprises concrete precast slabs, a concrete post-cast section and the connecting structure. Compared with the prior art, the prefabricated composite beam segment connecting structure has the advantages that production and installation cost is lowered, construction of projects is accelerated, total cost of the projects is lowered, and durability of the structure is improved.
