Temporary reinforcing method for steel truss girder sections
The invention discloses a temporary reinforcing method of a steel truss girder segment, and relates to the technical field of temporary reinforcing of the steel truss girder segment, and the temporary reinforcing method comprises the following steps: S1, drawing up a supporting point of the steel truss girder segment in a construction stage; s2, whether the steel truss girder sections need to be reinforced or not is judged; s3, selecting a double-side reinforcing scheme or a single-side reinforcing scheme; s41, a first reinforcing piece or a second reinforcing piece is additionally arranged according to the pull rod design, and a third reinforcing piece is additionally arranged according to the pull-press rod design; s42, additionally arranging a first reinforcing member and a second reinforcing member according to the design of the pull rod, and optionally additionally arranging a third reinforcing member according to the design of the pull rod; s5, judging whether the stress and deformation of the steel truss girder sections and the reinforcing members meet the design requirements or not; if yes, turning to S7; if not, turning to S6; s6, adjusting the sectional area and/or unstressed length of the reinforcing member, and then executing the step S5; and S7, finishing the design. According to the temporary reinforcing method, the economical efficiency of steel truss girder segment reinforcing measures is improved to the maximum extent.
本申请公开了一种钢桁梁节段的临时加固方法，涉及钢桁梁节段临时加固技术领域，包含以下步骤：S1.拟定施工阶段钢桁梁节段的支撑点；S2.判断是否需要对钢桁梁节段进行加固；S3.选用双侧加固方案或单侧加固方案；S41.按拉杆设计增设第一加固件或第二加固件，按拉压杆设计增设第三加固件；S42.按拉杆设计增设第一加固件和第二加固件，并可选的按拉杆设计增设第三加固件；S5.判断钢桁梁节段及各加固件的应力、变形是否均满足设计要求；若是，转S7；若否，转S6；S6.调整加固件的截面面积和/或无应力长度，然后执行步骤S5；S7.结束设计。本申请的临时加固方法，最大限度提高钢桁梁节段加固措施的经济性。
