[0016] As a preferred technical solution, the building body is provided with a slot, the slot shape is adapted to the fixed steel frame and the auxiliary support, and the slot depth is adapted to the depth of the mobile steel frame after contraction. When the podium is not in use, the podium structure is put into the building body to improve the aesthetics of the building body, and another convenience is to prevent the podium body from being exposed to wind and rain, thereby increasing the service life of the podium body.
[0017] As a preferred technical solution, a second gas rod is provided in the middle of the top of the steel frame to cooperate with the cylinder inside the channel steel guide rail, one end of the second gas rod is fixedly connected to the main body of the building, and the other end is connected to the outermost side of the fixed steel frame. A synchronous drive device is provided on the top of the podium to avoid uneven stretching of the upper and lower parts during the expansion and contraction of the podium, which may cause the top of the podium to tilt, thereby improving the stability of the podium.
[0018] The advantages and beneficial effects of the present invention are as follows: the auxiliary support design on both sides of the fixed steel frame improves the stability of the podium, and the podium still has good stability even in the case of strong winds and earthquakes. Compared with the prior art, the present invention provides an automatically retractable podium, which uses a motor or a gas rod to control the automatic retraction of the steel frame structure. When needed, the steel frame structure is unfolded outward to expand the use area of the main building, and when not needed, it is folded inward, does not occupy external space, and is easy to operate.
