Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a steel structure roof floating plate cantilever structure. Background Art

[0002] Steel structure roof cantilever plate, because the root and end of the cantilever are subjected to different bending moments, the thickness of the end of the cantilever plate is smaller than the thickness of the root. In general, at least two legs are set on the same radial surface of the cantilever plate to form a stable support, see Figure 2 This is because the center of gravity of the floating board is outside. If there is only one leg to support it, the floating board itself will inevitably bend and deform; this requires a concrete area of ​​sufficient width on the edge of the roof to connect the legs. However, for a glass roof, the width of the concrete area left on the edge of the roof is not enough to set up two legs, and the legs cannot be directly connected to the glass, so the conventional roof floating board support mechanism cannot be installed, which is a technical problem.

[0005] Preferably, the end of the extension beam is connected to two connecting rods, thereby increasing the connection points with the end of the extension beam; the two connecting rods are arranged in a herringbone shape, which also enables the connecting rods to apply force to the extension beam stably.
