The invention discloses a hoisting construction method for a main beam of a portal crane. The hoisting construction method comprises a hoisting construction process of hoisting the main beam on the basis of constructing a main beam hoisting system of the portal crane. On the basis of a main beam hoisting system of the portal crane, when a main beam is hoisted and lifted, a wind cable A, a wind cable B, a wind cable C and a wind cable D converge and intersect on ground anchors on the two sides and the middle of a track; the main beam of the portal crane is not prone to making contact with the wind cable A, the wind cable B, the wind cable C and the wind cable D to cause interference, and the problem that due to the fact that the lifting frame is located on the inner side of the supporting leg, the main beam of the portal crane can make contact with and collide with the lifting frame in the lifting process, and the lifting efficiency is affected is solved.
本发明公开了一种门式起重机主梁吊装施工方法,包括:以构建出门式起重机主梁吊装体系为基础将主梁起吊的吊装施工过程。以门式起重机主梁吊装体系为基础,在主梁起吊提升时,风缆绳A、风缆绳B、风缆绳C及风缆绳D内敛交汇在轨道两侧及中部的地锚上;门式起重机的主梁不会轻易与风缆绳A、风缆绳B、风缆绳C及风缆绳D接触造成干涉,解决了由于提升架在支腿内侧,存在门式起重机的主梁在提升时会接触碰撞到提升架影响吊装效率的问题。
