Multi-stage energy consumption falling object impact protection structure

Abstract

The invention discloses a multi-stage energy consumption falling object impact protection structure which comprises a stand column (4), a lever type displacement amplifying device (2) is installed on the stand column (4), a lever fulcrum is located at the top end of the stand column (4), a two-way cross net rack (1) is installed at the front end of a lever, and the tail end of the lever is connected with a column body of the stand column (4) through a damper (3). The invention provides a movable protective shed capable of preventing the impact effect through a multi-stage energy consumption device, and after the protective shed is placed on a construction site, falling objects with various impact energies can be prevented. When a falling object with small impact energy hits the surface of the anti-falling plate, the anti-falling plate can absorb the impact energy through self deformation, due to the fact that the anti-falling plate is fixed to the upper chord of the net rack through bolts, the anti-falling plate can be replaced after being subjected to one-time impact deformation, and when the falling object has large impact energy, the anti-falling plate can be replaced. And the multi-stage energy consumption device arranged on the protective shed can play a role.

Description

technical field [0001] The invention relates to an anti-falling object structure, in particular to a movable protective shed which prevents the impact of falling objects during high-altitude construction by arranging multi-stage energy-consuming devices, and belongs to the field of engineering construction. Background technique [0002] During the construction period, accidents such as falling objects frequently occur. If proper protective measures are not taken before construction, the incidents of falling objects will occur, ranging from damage to engineering facilities to endangering human life. For some subway reconstruction and expansion projects, any falling objects will seriously affect driving safety and cause traffic jams, and even cause urban traffic paralysis. [0003] At present, the anti-falling object protection structure set up during the construction period mostly adopts fixed and simple protective sheds, which seriously affects the construction on the ground...
