Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a falling object prevention device for building construction. Background Art
[0002] During the construction process, in order to prevent falling objects from high altitude from causing casualties to people at the bottom of the construction area, a falling object prevention device is generally set up in the construction area. This falling object prevention device is mainly composed of steel rods and anti-falling nets. When objects fall due to improper operation during construction, the fallen objects will fall on the top of the anti-falling net, thereby preventing the falling objects from falling directly to the ground.
[0003] Currently, the most common anti-fall device is to build a support frame from the bottom up through scaffolding, and then tension the protective net horizontally and directly on the outside at a certain height interval. Several cross bars need to be set in the horizontal direction for traction and tensioning. In this scheme, the blocking net and the cross bar are in direct contact, and the cross bar is rigidly fixed. Falling objects from high altitude will directly contact the cross bar, which will cause a very large impact on the support frame. When the impact force is too large, the anti-fall net is also easily damaged. Utility Model Content

[0011] Compared with the prior art, the utility model provides a falling object prevention device for construction, which has the following beneficial effects:
[0012] The falling object prevention device for construction use has the advantages that when falling objects fall onto the blocking net, the impact force of the falling objects acts on the blocking net, and the purpose of reducing the impact can be achieved through the damping rod under the blocking net, completing the initial buffering. At the same time, part of the impact force received by the damping rod can be transferred to the spring shock absorber through the cooperation of the connecting rod and the force arm, so as to attenuate the kinetic energy, suppress the impact, and complete further buffering. When the impact force is large, the leaf spring buffering can also be used to reduce the force.
