Method for assembling plate-truss combined beam of suspension bridge
The invention provides a suspension bridge plate-truss combined beam assembling method which comprises the following specific steps: step 1, assembling a steel truss, the assembling sequence of rod pieces of the steel truss is that a lower-layer rod piece, a rear facade rod piece and an upper-layer rod piece are sequentially assembled from bottom to top by using temporary bolts and punching nails,and the lower-layer rod piece is assembled into a plane structure with an opening at one end and a closed end; 2, detecting the installation precision of the steel truss assembled in the step 1, andreplacing temporary bolts and punching nails with high-strength bolts after the standard requirements are met; and 3, after the steel truss is assembled, the bridge deck slab is hoisted to the steel truss. The steel truss rod pieces form a closed stable structural system from bottom to top, the lower-layer rod pieces and the rear vertical-face rod pieces are arranged firstly, then the upper-layerrod pieces are installed, after the steel truss is assembled, the center distance and the diagonal difference of the main truss are checked, the next section can be assembled after the steel truss isdetected to be qualified, and the assembling quality of the plate-truss combined beam is guaranteed.
本发明提供一种悬索桥板桁结合梁拼装方法，具体步骤为：步骤一，拼装钢桁架，钢桁架的杆件拼装顺序为用临时螺栓和冲钉由下而上，先下层杆件，后立面杆件，再上层杆件，其中下层杆件拼成一端开口，另一端为闭口的平面结构；步骤二，将步骤一中拼装好的钢桁架进行安装精度的检测，满足规范要求后，将临时螺栓和冲钉替换成高强螺栓；步骤三，钢桁架拼装完成后，将桥面板吊装至钢桁架上。本发明中钢桁架杆件由下而上，先下层杆件，后立面杆件，最快形成闭合稳定的结构体系，然后安装上层杆件，钢桁架拼装完成后，检验主桁架中心距、对角线差，经检测合格后方可进行下一节段的拼装，保证板桁结合梁拼装质量。
