Description

TECHNICAL FIELD

[0002] The installation of a suspended ceiling suspender is a common link in the process of decoration. In the entire indoor decoration, it accounts for a considerable proportion. The suspended ceiling suspender applied to the top surface of a building can not only ensure the installation of indoor fresh air and water pollution pipelines, but also can be appropriately decorated, so as to not only realize the functions of indoor ventilation, water supply and drainage, and beautification of the indoor environment, but also create a colorful indoor space artistic image.

[0003] When the suspender is installed, a hole needs to be punched in the top of each floor, the suspender is fixed in the hole through an expansion bolt, the bottom end of the suspender is connected to a furring strip through a fitting, and a decorative plate is fixed and installed through the furring strip. In the process of installing the suspender, the suspender is taken as a screw rod in the expansion bolt and is installed into the hole together with the expansion bolt. First, the suspender is assembled with a hexagonal nut, a pipe expander and a washer to form an expansion bolt, the bottom end of the suspender is hammered with a hammer so that the expansion bolt is completely inserted into the hole, and then the hexagonal nut is tightened through a wrench or the like, so that the expansion bolt is firmly installed into the hole, and the suspender as a part of the expansion bolt is installed in place. However, in this installation process, the construction personnel need to climb the ladder for high-altitude operation, and the personnel stand on the ladder or the movable frame for operation:

[0004] 1. Since the top surface of the building is smooth, the safety belt and other safety measures of the construction personnel cannot be hung, the ladder and the frame are more likely to overturn, and there is a high safety hazard;

[0005] 2. Meanwhile, when the suspended ceiling suspender is installed in some small-bay space, the structure of a better safety person ladder cannot be unfolded, so that great safety hazards are caused to the construction workers during use, the construction workers need to be more careful and cautious when standing at a high place for operation, the working surface is limited, and the construction workers need to repeatedly climb up and down, which causes great physical consumption to the workers;

[0006] 3. When the construction personnel use the ladder and the frame to assist in operation for suspender installation, since the ladder itself is movable and needs to cross the space for operation, the construction personnel need to frequently move the climbing frame for high-altitude operation, which not only consumes time, but also consumes more physical strength, and the construction efficiency is low;
