Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of steel structure construction, specifically relates to a device for synchronous lifting and transverse moving of steel hanger and large-span steel ceiling. BACKGROUND

[0002] Glass ceiling is often used as a lighting roof in many high-rise buildings due to its beautiful appearance and excellent lighting performance. In these buildings, the connection method of the steel ceiling in the air and the two side buildings mainly includes strong connection and weak connection. Among them, the weak connection method is widely used because it has smaller constraint on the deformation of the two side buildings and smaller stress on the steel ceiling, and it is more cost-saving.

[0003] However, the distance between the steel ceiling and the surrounding buildings is usually small, and there is a lack of construction space. In the case where a large crane cannot be used, the construction of the steel ceiling is often similar to the corridor, and the lifting method is often used for installation. Specifically, before installing the steel ceiling, a hanger needs to be reserved on the two side buildings. During the construction process, the steel ceiling needs to be lifted to a certain height and then the hanger is made and lifted to the bottom of the steel ceiling and fixed and installed with the reserved hanger. This method needs to be lifted twice continuously, and the construction efficiency is low.

[0004] At present, there is also a method of hanging the hanger on the bottom of the main structure through the steel wire rope, and lifting the hanger together with the main structure. However, this method is prone to shaking during lifting, which leads to unstable lifting, and it is difficult to pause and fine-tune the lifting posture during the lifting process. In addition, after being lifted to the specified position, the hanger needs to be manually dragged to the installation position, which not only has a large operation difficulty, but also has a high risk. Therefore, it is necessary to develop a simple device to solve the technical problems of the steel hanger installation, so as to improve the construction efficiency and safety.
