Description

Sliding device for installing roof large-span daylighting roof steel girder Technical Field The utility model belongs to the field of construction equipment, and particularly relates to a sliding device for installing a roof large-span daylighting roof steel beam. Background In large-scale buildings, steel structures are mostly adopted for the design of roof daylighting roofs, and the roof daylighting roof has the advantages of large span, convenience in installation, rapidness in construction, light self weight of the structure and the like. However, the installation of the large-span daylighting roof girder cannot be carried out in a whole root for hoisting due to the limitation of the position and the span. The traditional construction method mostly adopts a bracket method, namely a support frame is arranged at the subsection position of the steel beam, and the steel beam is hoisted in a subsection manner. The support method has the limitations that (1) the construction period is prolonged due to the long construction period for erecting and dismantling the support frame. (2) Most of the lighting roof is an atrium space below, and the height of the support frame is higher, so that the measure cost is obviously increased. (3) In some cases, the tower crane or the large-sized automobile crane has higher use cost, and particularly when the daylighting roof steel beam is positioned in the center of a building, the hoisting operation radius is larger, and heavy equipment support is needed, so that the construction cost is further increased.
