Steel beam pier replacement coating process
The invention discloses a steel beam pier replacement coating process and belongs to the technical field of steel structure bridge manufacturing. The steel beam pier replacement coating process comprises the following steps that: a set pier position marking line and a temporary pier position marking line are drawn on a bottom plate of a small section; sand blasting rust removal is carried out at the set pier marking line in a weld joint grinding interval in a box; primer with specified film thickness is sprayed according to the outer surface system of the steel beam of the small section; an accurate pier position marking line is drawn on the bottom plate of the small section; the small section is transported into a coating workshop, second steel piers are aligned with the accurate pier position marking line, and the small section is supported through the second steel piers; and coating construction is performed on the inner and outer surfaces of the small section according to a coatingprocess. By means of the steel beam pier replacement coating process adopted, time consumed by a beam transporting trolley can be effectively shortened, the pier replacement coating labor intensity of the beam transporting trolley is relieved, a pier replacement repair construction period is shortened, manufacturing cost is greatly reduced, and steel beam construction coating appearance quality is improved.
本发明公开了一种钢梁换墩涂装工艺，属于钢结构桥梁制造技术领域。所述钢梁换墩涂装工艺包括以下步骤：在小节段的底板上画设定墩位标线及临时墩位标线；在箱内焊缝打磨区间内，在设定墩位标线处进行喷砂除锈；按小节段的钢梁外表面体系喷涂规定膜厚的底漆；在小节段的底板上画精确墩位标线；将小节段运输至涂装厂房内，使第二钢墩对准精确墩位标线，通过第二钢墩支撑所述小节段；按涂装工艺对小节段进行内外表面的涂装施工。本发明钢梁换墩涂装工艺可有效降低运梁小车占用时间，减轻其换墩涂装劳动强度，缩短了换墩修补施工周期，极大的缩减了制造成本，提高钢梁施工涂装外观质量。
