Large-segment bridge steel box girder segment hoisting high-altitude closing equipment and method
The invention discloses large-segment bridge steel box girder segment hoisting high-altitude folding equipment and method.The equipment is provided with a supporting combined frame, an adjusting auxiliary structure and a limiting piece, the supporting combined frame is composed of a first supporting frame and a second supporting frame, and the adjusting auxiliary structure is provided with a first movable block and a second movable block; a first inter-seam block is fixed to the first movable block, a second inter-seam block is fixed to the second movable block, the first inter-seam block and the second inter-seam block form an inter-seam supporting piece, the width of the inter-seam supporting piece is adjustable so as to control the welding distance between steel box girders to be installed, and the limiting piece limits the moving range of the second inter-seam block. And after the limiting piece is detached, the minimum width of an inter-seam supporting piece formed by combining the first inter-seam block and the second inter-seam block is reduced, so that the inter-seam supporting piece can be detached from the position between the to-be-installed steel box girders. According to the method, the width of the supporting piece between the seams is adjusted according to the welding distance needed by different construction conditions, and the method can be used for adjusting the welding distance in different construction states and can be repeatedly used.
本发明公开了一种大节段桥梁钢箱梁分段吊装高空合拢设备及方法，其中，设备具备支撑组合架、调节辅助结构和限位件，支撑组合架由第一支撑架和第二支撑架组成，调节辅助结构具备第一活动块和第二活动块，第一活动块上固定有第一缝间块，第二活动块上固定有第二缝间块，第一缝间块和第二缝间块形成缝间支撑件，缝间支撑件的宽度可调，以控制待安装钢箱梁之间的焊接间距，限位件限制第二缝间块的活动范围，以及在拆卸限位件之后第一缝间块和第二缝间块组合形成的缝间支撑件的最小宽度变小，以能够从待安装钢箱梁之间拆除。本发明中，根据不同施工情况所需要的焊接间距调整缝间支撑件的宽度，可用于不同施工状态的焊接间距的调整，可重复利用。
