悬臂拼装是将预制好的节段,用支撑在已完成的悬臂上的专门悬拼吊机悬吊于梁位上逐段拼装。一个节段张拉锚固后,再拼装下一节段。悬臂现浇、悬臂拼装适用于预应力混凝土T形钢构桥、连续梁桥、斜拉桥和拱桥等的修建。一、梁段预制、吊运的规定1梁段预制应在台座上连续啮合预制。钢筋、混凝土和预应力管道安装应符合规范规定。2梁段的存放场地应平整,承载力满足要求。支垫位置与吊点一致。
Cantilever assembly is the prefabricated section, with the support of the completed cantilever hanging suspension crane suspended in the beam position by piece assembly. After a section of the anchor tension, and then assembled the next section. Cantilever cast-in-place, cantilever assembly is suitable for the construction of prestressed concrete T-shaped steel bridge, continuous beam bridge, cable-stayed bridge and arch bridge. First, the beam prefabricated, lifting provisions 1 Beam prefabricated should be continuously engaged in prefabricated pedestal. Reinforced, concrete and prestressed pipe installation shall comply with the rules and regulations. 2 Beam segment storage site should be smooth, bearing capacity to meet the requirements. Pad position consistent with the lifting point.
