Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building engineering, especially relates to a hoisting device for buckling restrained brace. BACKGROUND

[0002] Buckling restrained brace is mainly used in buildings and bridges to enhance seismic performance. The traditional support structure is prone to buckling when bearing axial load, thereby reducing its carrying capacity. Buckling restrained brace can effectively prevent or delay the buckling phenomenon of the support member through special design and manufacturing process. After the support member is transported to the predetermined position, the central part is fixed using a lifting chain to temporarily stabilize the support and prevent it from shifting or tilting before final fixation. During installation, if there is a size error or deviation, it cannot be quickly corrected by adjusting the connection position of the lifting chain and the support, which may require disassembly and reinstallation, causing waste of time and resources. Due to the lack of adjustment capability of the lifting chain used to fix the support in related technology, the support cannot be accurately positioned, affecting the stability and safety of the overall structure. Moreover, in the face of different construction site conditions, the fixed connection position may not meet the specific requirements, requiring additional adjustment or changing other structures, increasing complexity.
