Description

Super high-rise steel beam hoisting sling

Technical Field

The utility model relates to a hoist technical field for the building especially relates to a superelevation layer girder steel hoist and mount hoist.

Background

Along with the faster and faster development of cities, the urban land is more and more tense, and the development height of house buildings is determined to be larger and larger. The structural selection of the super high-rise building is different from place to place according to different earthquake intensity and earthquake fortification intensity areas. At present, the mainstream structure form of house buildings with the height of more than 100 in China is a frame and core tube structure. Namely, the interior is a core tube made of reinforced concrete, and the exterior is a frame structure. The outer frame structure has a round pipe column and a steel beam, a box column and a steel beam, and a steel reinforced concrete column and a steel reinforced concrete beam. Therefore, no matter what type is selected, the outer frame uses the section steel beams. The H-shaped steel beams are the most of the shaped steel beams. If the outer frame is in the form of a circular pipe column plus a steel beam or a box column plus a steel beam, the construction organization of the core barrel and the outer frame is an unequal-height synchronous construction principle, namely the core barrel is vertically upwards increased, and the outer frame is horizontally and vertically upwards increased synchronously at 6 layers lower than the core barrel. Therefore, the time node of the first capping of the main structure of the super high-rise building depends on the construction progress of the core barrel, but the time node of the whole capping of the main structure depends on the construction progress of the outer frame. And the time node of the whole capping of the main structure directly influences the construction completion node of the subsequent secondary structure, electromechanics, curtain wall and finish decoration. Therefore, the construction progress of the outer frame is very important for the construction organization of the whole project.
