Prefabricated steel-concrete combined prestressed beam construction method and prefabricated steel-concrete combined prestressed beam
The invention relates to the technical field of bridge construction, in particular to a prefabricated steel-concrete combined prestressed beam construction method and a prefabricated steel-concrete combined prestressed beam. The construction method of the prefabricated steel-concrete combined prestressed beam comprises the following steps that prefabricated ultra-high-performance concrete panels are arranged on prefabricated steel beams in a segmented mode, the prefabricated steel beams and the prefabricated ultra-high-performance concrete panels are connected through connecting pieces, and a gap is reserved between every two adjacent prefabricated ultra-high-performance concrete panels; after the connection of the prefabricated steel beam and the prefabricated ultra-high performance concrete panel reaches the preset strength, external force is applied to the composite beam so that the composite beam can be bent upwards to reach the preset value; and the gap is filled with a connecting structure so that the two adjacent prefabricated ultra-high-performance concrete panels can be connected, and the external force is relieved. The construction method of the prefabricated steel-concrete combined prestressed beam and the prefabricated steel-concrete combined prestressed beam are simple in construction and low in precision requirement.
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预应力梁施工方法及预制钢混组合预应力梁。预制钢混组合预应力梁施工方法，包括以下步骤：在预制钢梁上分段设置预制超高性能混凝土面板，预制钢梁和预制超高性能混凝土面板通过连接件连接，相邻两段预制超高性能混凝土面板之间预留有缝隙；待预制钢梁与预制超高性能混凝土面板的连接达到预定强度后，对组合梁施加外力使其向上弯曲达到预设值；向缝隙中填充连接结构，以将相邻两段预制超高性能混凝土面板连接，并解除外力。本发明提供了一种施工简单，精度要求低的预制钢混组合预应力梁施工方法及预制钢混组合预应力梁。
