Manufacturing method of bridge portal frame
The invention provides a manufacturing method of a bridge portal, and relates to the technical field of bridge erection, and the manufacturing method comprises the following steps: prefabricating an included angle between a first edge and a second edge on an angle plate as a preset angle; the upper ends of the first side web, the middle web and the second side web abut against the first side flange plate, the middle flange plate and the second side flange plate according to the flange plate assembly line; the first edge and the second edge abut against the first side web plate and the first side wing edge plate and are fixedly connected; the first edge and the second edge of the angle plate abut against the middle web plate and the middle flange plate correspondingly, and the middle flange plate is fixedly connected with the middle web plate; the first edge and the second edge of the angle plate abut against the second side web and the second side flange plate correspondingly, and the second side flange plate is fixedly connected with the second side web; the first side frame is connected to one end of the midspan, and the second side frame is connected to the other end of the midspan. The accuracy of the included angle between the flange plate and the web plate is ensured through the first edge and the second edge which are adjacent to each other of the angle plate, so that the assembly accuracy of the bridge portal frame is ensured.
本发明提供了一种桥门架的制造方法，涉及桥梁架设技术领域，包括：将角板上的第一边和第二边夹角预制为预设角度；根据翼缘板拼装线将第一侧腹板、中腹板和第二侧腹板的上端抵接于第一侧翼缘板、中翼缘板和第二侧翼缘板；将第一边和第二边抵接于第一侧腹板和第一侧翼缘板，并固定连接；将角板的第一边和第二边分别抵接于中腹板和中翼缘板，并将中翼缘板与中腹板固定连接；将角板的第一边和第二边分别抵接于第二侧腹板和第二侧翼缘板，并将第二侧翼缘板与第二侧腹板固定连接；将第一侧架连接于中跨的一端，将第二侧架连接于中跨的另一端。本发明通过角板相邻的第一边和第二边来确保翼缘板与腹板之间的夹角精确性，进而保证桥门架的装配精度。
