Description

Technical Field

[0001] This utility model relates to the field of steel structure construction technology, and specifically discloses a high roof steel structure lifting frame. Background Technology

[0002] With the development of steel structure construction technology, in order to better showcase design concepts and highlight architectural forms, more large-span public buildings are beginning to use steel structures as the main structure or roof. These buildings employ steel-concrete composite column supports combined with spatial curved grid roof structures, involving a significant amount of lifting work on steel trusses or grid structures. Lifting construction of steel structures requires the use of lifting platforms. During the installation of steel trusses, lifting platforms are typically used to hoist the trusses to a set height. Lifting platforms are one of the essential construction tools in the steel truss hoisting process. Due to the complexity of the roof space shape, steel components at different nodes need to be lifted to various different heights. The height of the lifting platform must be easily adjustable. Because steel structural components are large and heavy, the lifting platform needs to have strong stability to ensure the safety of the lifting process. Utility Model Content

[0003] The purpose of this utility model is to provide a high-roof steel structure lifting frame with high support stability and convenient adjustable lifting height.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-roof steel structure lifting frame includes a supporting structure, a fixed structure at the bottom of the supporting structure, a supporting platform at the top of the supporting structure, and a hydraulic lifting device above the supporting platform. The supporting structure includes two parallel, spaced-apart support frames. Each support frame includes multiple standard sections, each standard section being a rectangular frame. These standard sections are vertically stacked and assembled into a rectangular frame structure. Each standard section includes four uprights and web members between adjacent uprights. The web members are welded and fixed between adjacent uprights. Connecting steel plates are provided at both ends of the four uprights, and the middle of the connecting steel plates is welded... Fixed to the end of the column, the connecting steel plate has multiple bolt holes. The support platform includes two pad beams respectively located at the top of the two support frames, and a platform beam simultaneously located above the two pad beams. The pad beams are U-shaped structural beams made of welded I-beams. The lower flange of the pad beams is fixed to the connecting steel plate at the top of the column by bolts. The platform beam is an I-shaped structural beam made of welded I-beams. The platform beam includes a connecting part and a fixing part vertically located at both ends of the horizontal part. The two fixing parts of the platform beam are welded and fixed to the top surfaces of the two pad beams respectively. The hydraulic lifter is located in the middle of the connecting part of the platform beam.

[0006] Furthermore, the support frame is provided with a bottom beam, which is a U-shaped structural beam made of welded I-beams. The upper flange of the bottom beam is fixed to the connecting steel plate at the lower end of the column by bolts.

[0007] Furthermore, the fixing structure includes buried steel bars and a reinforcing steel plate fixed to the upper end of the buried steel bars, and the lower flange of the bottom beam is fixedly connected to the reinforcing steel plate by bolts.
