Description

Technical Field

[0001] The present invention relates to the technical field of steel structure connecting corridors, and particularly relates to an anti-wind device for integral lifting of a steel structure connecting corridor. Background Technique

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and rust removal and anti-rust processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. A connecting corridor refers to a passage under the eaves, a passage inside a house or an independent covered passage, including a cloister and a veranda, and has functions such as sunshading, rain protection, and taking a short rest. On the one hand, due to architectural functional requirements, a steel structure connecting corridor can facilitate the connection between two towers. At the same time, the connected body has good lighting effects and a broad view and can be used as an observation corridor. On the other hand, due to the setting of the connecting corridor, the building appearance can be made more distinctive and a more harmonious architectural atmosphere can be created.

[0003] At present, during the lifting construction of existing steel structure connecting corridors, the connecting corridors are mostly hoisted directly by ropes. Since the installation height of building connecting corridors is usually relatively high, during the lifting process, the high-altitude air flow is likely to have a greater impact on the steel structure connecting corridors, causing the hoisted connecting corridors to swing violently, thus greatly affecting the stability and reliability of the overall lifting, with poor anti-wind protection effect and poor safety. Summary of the Invention

[0004] The purpose of the present invention is to provide an anti-wind device for integral lifting of a steel structure connecting corridor. By setting two sets of support trusses, and arranging a connecting plate, a strengthening arm and a support seat between the two sets of support trusses to form a lifting frame, and with the cooperation of structures such as a winding roller, a connecting rope, a guide wheel group and a guiding component, the lifting frame can be stably lifted and lowered in a straight line between the two sets of support trusses, so as to carry out the lifting construction of the steel structure connecting corridor, thereby effectively avoiding the shaking caused by direct hoisting, with stable and reliable overall lifting, good anti-wind protection effect, and greatly improving the safety and stability during construction operations, so as to solve the above deficiencies in the technology.
