Description

Technical Field

[0001] The utility model relates to the field of building construction lifting equipment, and more specifically, to an assembled building construction lifting device. Background Art

[0002] In the process of building construction, many structural components of buildings are prefabricated. When the building is constructed, it is only necessary to connect the prefabricated components to the main body of the building to complete the installation of the building structure. Prefabricated components are an important part of prefabricated buildings. When installing prefabricated components, it is often necessary to raise the components to a certain height. Therefore, a lifting device is required to lift the prefabricated components. The existing lifting device is generally a frame or plate structure. By tying the components to the frame or supporting the components through a supporting plate, the lifting device and the components are lifted by a crane or the like. The components are lifted together to the required position. The existing lifting devices generally lack adjustment structures. The components cannot be stably placed in the frame or on the supporting plate only by binding. As a result, the components and the lifting devices will move relative to each other during the lifting process, which affects the normal lifting. In addition, the existing lifting devices are generally only suitable for lifting block-shaped or columnar components, and are not convenient for lifting plate-shaped components. When the plate-shaped components are heavy and need to be installed vertically, the plate-shaped components are placed flat on the lifting devices. After lifting them to the required position, it is inconvenient to erect the plate-shaped components, which makes it inconvenient to install the plate-shaped components. Utility Model Content
