Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a steel structure hoisting device which utilizes existing structural columns to lift on-site. Background Art

[0002] In construction, steel structure is a very important type of building structure, with many advantages such as high strength, light weight, good rigidity, strong toughness, etc., so it is widely used. Some large steel structures often weigh tens or hundreds of tons, and the lifting of these steel structures is mainly completed by large hoisting equipment. However, under some special difficult conditions, such as the small space around the site, the influence of obstacles or the inability to be removed, large hoisting equipment cannot enter the work area. Under such space-limited working conditions, hoisting work is very difficult to carry out. Utility Model Content

[0003] In view of the shortcomings of the prior art, the utility model designs a steel structure lifting device for on-site lifting using existing structural columns, comprising: a lifting device, a lifting device, a fixed bracket and an installation bracket; the lifting device is installed on the steel structure frame to be lifted; the lifting device is arranged directly above the lifting device, and the lifting device is installed on the fixed bracket; the fixed bracket is fixedly connected to the installation bracket; the installation bracket is installed on the existing structural column.

[0004] Preferably, there is one lifting device, which is installed on one side of the fixed bracket.

[0005] Preferably, the steel structure hoisting device is installed on a structural column at an edge position.

[0006] Preferably, there are two lifting devices, which are respectively installed on both sides of the fixed bracket.

[0007] Preferably, the steel structure hoisting device is installed on a structural column at a middle position.

[0008] Preferably, the lifting is carried out by using a plurality of steel structure lifting devices in cooperation with each other, and the plurality of steel structure lifting devices are all connected to the control system.

[0009] Preferably, a control unit is provided in the lifting device, and the control unit is connected to the control system.

[0010] Preferably, the mounting bracket is installed on the top or side of the existing structural column; the structure of the mounting bracket is determined according to the construction site.

[0011] Compared with the closest prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model utilizes the existing structural columns that have been constructed and installs the lifting device on the existing structural columns. This on-site lifting method does not require large-scale lifting equipment to complete the lifting. When the space is limited, the large-span steel structure bracket can be quickly lifted.

[0013] 2. The utility model sets different numbers of lifting devices according to the positions of the existing structural columns, which can avoid the situation where there are too few lifting devices and the lifting force is insufficient, and can also avoid the situation where there are too many lifting devices and the waste is caused. It not only ensures the safety of construction, but also avoids the waste of financial and material resources.

[0014] 3. The utility model can be used in conjunction with multiple steel structure hoisting devices, which are connected through the same control system. This can ensure that the steel structure support is lifted at multiple points during the lifting process, reduce the deformation of the steel structure support during the lifting process, and ensure the quality of the final forming.

[0015] 4. The installation bracket of the utility model is adjusted according to the situation on site. The principle of adjustment is to ensure the strength of the installation bracket without collision with the steel structure bracket during the hoisting process, which increases the flexibility of construction and ensures the progress and safety of construction.
