Segmented in-situ splicing construction method for large special-shaped steel anchor beam
The invention relates to a large special-shaped steel anchor beam segmentation in-situ assembly construction method. A sliding position control body is arranged between a sliding pressing plate and an adjacent sliding groove supporting column, and a transverse position control body is arranged on the side facing a stiff framework; a first side pressure bolt, a second side pressure bolt and a third side pressure bolt are arranged on the side wall of the anchor beam back plate; a vertical position correcting body and a lifting guide groove are arranged on the platform top plate, and the vertical position and the transverse position of the lower-layer steel anchor beam are corrected through the vertical position correcting body and the first position correcting bolt respectively; the two side faces of the anchor beam back plate are heated and cooled through the first temperature control pipe and the second temperature control pipe correspondingly; a supporting frame hanging plate is arranged on the lower-layer steel anchor beam, supporting frame stand columns are connected with a groove top hanging plate through inclined hanging bolts, and a transverse connecting bolt is arranged between the two supporting frame stand columns; and the vertical position and the transverse position of the upper-layer steel anchor beam are controlled through the third position correcting bolt and the second position correcting bolt correspondingly. The installation efficiency and accuracy of the anchor beam back plate and the steel anchor beam are improved, and welding temperature deformation of the large-thickness steel plate is reduced.
本发明涉及一种大型异形钢锚梁分节原位拼装施工方法，在滑移压板与临近的滑槽撑柱之间设置滑移控位体，面向劲性骨架侧设置横向控位体；锚梁背板的侧壁上设置第一侧压栓、第二侧压栓和第三侧压栓；在平台顶板上设置竖向校位体和吊放导向槽，分别通过竖向校位体和第一校位栓校正下层钢锚梁的竖向和横向位置；通过第一温控管和第二温控管分别对锚梁背板的两侧面进行升温和降温；在下层钢锚梁上设置撑架挂板，并在撑架立柱与槽顶挂板通过斜向挂栓连接，并在两撑架立柱之间设置横向连栓；分别通过第三校位栓和第二校位栓控制上层钢锚梁的竖向位置和横向位置。本发明提高了锚梁背板和钢锚梁的安装效率和准确度，减小了大厚度钢板焊接温度变形。
