The invention provides a DSA hanger rail, hanger frame and main beam integral lifting and hoisting construction method, and belongs to the technical field of large equipment hoisting construction. The construction process comprises the following steps: positioning a sky rail positioning line, mounting a chemical anchor bolt rear embedded plate, welding a channel steel lifting column, welding a lifting cross beam, mounting an electric hoist, lifting a channel steel main beam and rechecking the levelness of the channel steel main beam, welding the channel steel main beam, welding an inclined strut and an additional lifting column, welding a DSA lifting frame, painting antirust paint and finish paint, and transferring to a manufacturer for acceptance. Installing equipment; the chemical anchor bolt rear-mounted embedded plate is used as a force transmission component between the steel frame and the main body structure, the channel steel davit, the channel steel main beam, the inclined strut, the hoisting cross beam, the additional davit and the like are assisted, and a suspension steel frame system which is safe and reliable in structure, meets the equipment requirement in levelness and can be used for fixing a DSA hanger rail and equipment is formed through welding.
本发明提供一种DSA吊轨吊架主梁整体提升吊装施工方法,属于大型设备吊装施工技术领域,本发明施工流程为:定位天轨定位线→安装化学锚栓后置埋板→焊接槽钢吊柱→焊接起吊横梁→安装电动葫芦→起吊槽钢主梁并复核其水平度→焊接槽钢主梁→焊接斜撑及附加吊柱→焊接DSA吊架→涂刷防锈漆及面漆→移交厂家验收、安装设备;本发明以化学锚栓后置埋板为钢架与主体结构之间的传力构件,并辅助槽钢吊柱、槽钢主梁、斜撑、起吊横梁和附加吊柱等,焊接形成结构安全可靠的、水平度满足设备要求的、可用于固定DSA吊轨及设备的悬吊钢框架体系。
