Prefabricated steel-concrete composite beam and construction method thereof
The invention relates to the technical field of bridge construction, in particular to a prefabricated steel-concrete composite beam and a construction method thereof. A prefabricated steel-concrete composite beam comprises a supporting section arranged on a bridge pier and comprising a first prefabricated steel beam and a first prefabricated concrete panel which are connected with each other, and a first stiffening plate is arranged on a first bottom plate of the first prefabricated steel beam close to the end part; the side span section comprises a second prefabricated steel beam and a second prefabricated concrete panel which are connected with each other, a second stiffening plate is arranged at the end, close to the supporting section, of a second bottom plate of the second prefabricated steel beam, and the second stiffening plate extends to the outer side of the second bottom plate so as to be in lap joint with the first stiffening plate; and the fastener penetrates through the supporting section, the first stiffening plate and the second stiffening plate so as to fix the supporting section and the side span section. The prefabricated steel-concrete composite beam and the construction method thereof are high in construction efficiency and small in influence on traffic or a river channel.
本发明涉及桥梁施工技术领域，具体涉及一种预制钢混组合梁及其施工方法。一种预制钢混组合梁，包括：支撑段，设于桥墩上，包括相互连接的第一预制钢梁和第一预制混凝土面板，所述第一预制钢梁的第一底板上靠近端部设有第一加劲板；边跨段，包括相互连接的第二预制钢梁和第二预制混凝土面板，所述第二预制钢梁的第二底板靠近所述支撑段的端部设有第二加劲板，所述第二加劲板延伸至所述第二底板的外侧，以与所述第一加劲板搭接；紧固件，贯穿所述支撑段、第一加劲板和第二加劲板设置，以将所述支撑段和边跨段固定。本发明提供了一种施工效率高，对交通或河道的影响较小的预制钢混组合梁及其施工方法。
