Variable cross-section continuous beam trial assembly method
The invention provides a variable cross-section continuous beam trial assembly method. The variable cross-section continuous beam is provided with a staggered slab and a corner at the beam section connecting position. The variable cross-section continuous beam trial assembly method comprises the following steps that the state considering the elevation and the pre-camber after bridge forming is defined as a first state; in the first state, the line shape of the beam section with the staggered slab and the corner is adjusted to be a smooth transition curve, and a second state is formed; in the second state, the main longitudinal beams are horizontally arranged and continuously matched and spliced; in the first state, the cross beams, the cross braces and the small longitudinal beams are assembled in a matched mode; defining the state of the beam section in the vertical position state after down-warping due to self weight as a third state; and in the third state, the main longitudinal beams, the cross beams, the cross braces and the small longitudinal beams are spliced. According to the variable cross-section continuous beam trial assembly method, trial assembly of the beam sections with staggered platforms and corners at the splicing positions can be facilitated.
本发明提供了一种变截面连续梁试拼装方法，所述变截面连续梁在梁段连接处设有错台和转角所述变截面连续梁的试拼装方法包括以下步骤：将考虑成桥后标高及预拱度的状态定义为第一状态；在所述第一状态下将有错台和转角处的梁段线形调整成匀顺平滑的过渡曲线，形成第二状态；在所述第二状态下将主纵梁平位布置，连续匹配拼装；在所述第一状态下对横梁、横撑和小纵梁进行匹配拼装；将梁段立位状态下因自重下挠后的状态定义为第三状态；在所述第三状态下对所述主纵梁、所述横梁、所述横撑及所述小纵梁进行拼装。本发明提供的变截面连续梁试拼装方法能够方便拼接处设有错台和转角的梁段的试拼装。
