Description

Technical Field

[0001] The utility model relates to the technical field of scaffolds, in particular to a construction frame for buildings with high safety performance. Background Art

[0002] The construction frame is also called the construction scaffold. It is a working platform set up to ensure the smooth progress of each construction process. It is an important auxiliary facility for construction work. The traditional construction frame generally includes four vertical bars arranged in a rectangular shape. A lower cross bar is connected between the lower parts of any two adjacent vertical bars. The rectangular plate is fixed to the four vertical bars and is located on the upper part of the vertical bars. A ladder is provided between the lower cross bar and one side of the rectangular plate. People can climb up to the rectangular plate through the ladder and then stand on the rectangular plate for construction. However, the height of the traditional construction frame is fixed and cannot be adjusted. There is a certain risk when climbing without a fence. In addition, when people on the construction frame need tools, the staff below need to hand them to the staff above, and the staff above bends down and leans out to receive them, which is dangerous and cannot meet people's use.

[0033] The working process of the utility model is as follows: a construction frame with high safety performance designed by the present invention is used. When the construction frame is used on a construction site, the lockable universal wheel 2 is used to facilitate the movement of the device. After stopping the brake, the first electric telescopic rod 3 is driven to extend to drive the support pad 4 to descend and fit closely to the ground, so that the device is more stable and convenient for the staff to use. After the staff stands on the lifting platform 13, the railing 15 is used to increase the safety protection. The servo motor 11 drives the second bevel gear 12 to rotate and drives the first bevel gear 9 to rotate. The rotation of the first bevel gear 9 drives the bidirectional threaded rod 6 to rotate.
