Description

Technical Field

[0001] This utility model relates to the field of steel structure lifting platform construction technology, and in particular to a column-supported single-sided lifting platform structure with a transfer beam. Background Technology

[0002] With the development of the construction industry, more and more roofs are adopting spatial steel truss structures. For steel truss structures with large spans and heights, especially for the lifting construction of roof steel trusses, building a lifting platform is one of the preferred options for convenient construction. However, some roof steel truss lifting construction operations are in complex environments, and conventionally constructed lifting platforms are difficult to adapt to the needs of the site. It is necessary to build a suitable lifting platform based on the site environment. Some lifting platforms are built based on on-site columns. In addition to relying on on-site columns, the load-bearing points of the lifting platform also need to find bottom support. When the lifting platform is built to a high height, the bottom of the lifting platform often needs to be fully constructed, which is time-consuming and labor-intensive, and the overall construction of the lifting platform is quite difficult. Utility Model Content

[0003] The purpose of this utility model is to provide a single-sided support lifting platform structure with a transfer beam. In the process of steel structure lifting construction with high height and complex on-site construction environment, a lifting platform with low cost, high safety, strong site adaptability and high stability can be erected by relying on on-site columns and transfer beams.

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

[0005] A single-sided support lifting platform structure with a transfer beam includes a support column, a transfer beam located on one side of the support column, a support frame mounted on the support column and the transfer beam, and a hydraulic lifter mounted on the support frame. The support frame includes a rear column at the top of the support column, two front columns on one side of the support column, and a platform beam horizontally positioned at the top of the rear and front columns. The rear column is vertically fixed to the top of the support column on the side away from the front columns. The transfer beam is a horizontally arranged I-beam. The two front columns are vertically spaced apart, with the bottom of the front columns connected and fixed to the top surface of the upper flange of the I-beam. Multiple sets of connecting rods are provided between the front columns and the support column, with these sets of connecting rods vertically evenly spaced. Each set of connecting rods includes a platform beam located on the top of the support column and the transfer beam. A first connecting strip is provided between the two front columns, and two second connecting strips are respectively provided between the two front columns and the support column. The first connecting strip is horizontally fixed between the two front columns. The first connecting strip and the two second connecting strips are arranged in a triangular structure. The two second connecting strips are horizontally fixed between the two front columns and the support column. A pad beam is provided horizontally at the top of the two front columns. The pad beam is a box beam. The length of the pad beam is greater than the distance between the two front columns. The bottom surface of the pad beam is welded and fixed to the top of the two front columns. The top surface of the pad beam is flush with the top of the rear column. The bottom surface of the platform beam is welded and fixed to the top of the rear column and the middle of the top surface of the pad beam. One end of the platform beam welded to the pad beam extends out of the pad beam. The hydraulic lifter is provided at the end of the platform beam that extends out of the pad beam.

[0006] Furthermore, the top surface of the I-beam is provided with two positioning ribs, and the bottom ends of the two front columns are respectively fitted onto the two positioning ribs.

[0007] Furthermore, the I-beam is provided with two sets of stiffening plates, which are respectively located at the bottom of two positioning ribs. Each set of stiffening plates includes two steel plates symmetrically arranged on both sides of the web of the I-beam. The top edge, bottom edge and one side edge of the steel plates are welded and fixed to the bottom side of the upper flange of the I-beam, the top side of the lower flange of the I-beam and the web of the I-beam, respectively.

[0008] Furthermore, the front column, rear column, lintel one, and lintel two are all round tubes.

[0009] Furthermore, a gap is left between the two connecting strips and the connection ends of the supporting column.

[0010] Furthermore, there are three and four lacing strips respectively between the front column and the rear column, and between the pad beam and the rear column. Both lacing strips three and four are round tubes. The two ends of lacing strip three are welded and fixed to the front column and the rear column respectively, and the two ends of lacing strip four are welded and fixed to the pad beam and the rear column respectively.

[0011] Furthermore, the platform beam is a box beam, and the specifications of the platform beam are larger than those of the pad beam.

[0012] Compared with the prior art, this utility model has the following features and beneficial effects:

[0013] This utility model utilizes a transfer beam located on one side of the supporting column, a support frame mounted on both the supporting column and the transfer beam, and a hydraulic lifter mounted on the support frame. This allows for the construction of a lifting platform that is cost-effective, safe, adaptable to various sites, and highly stable, especially in high-altitude and complex on-site steel structure lifting operations. The platform is constructed by using the supporting column and the transfer beam as lateral and bottom support points, respectively. This avoids the need for a full-area erection to find bottom support, thus improving the efficiency and stability of the lifting platform, saving time and resources. It is safe, applicable, and has significant practical value, and its widespread application will generate substantial economic benefits. Attached Figure Description
