Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and more specifically, particularly relates to a building material falling interception net. Background Art

[0002] During the building construction process, it is necessary to cover a layer of interception net on the building surface to avoid accidents caused by the falling of building materials or construction tools. Most of the existing interception nets are composed of a net body, edge ropes, tie ropes and rib ropes, and most of the interception nets are fixed on the steel frame by bolts or steel wires during installation.

[0003] For example, CN211524151U discloses a protective net for building construction, which relates to the technical field of building engineering, specifically a protective net for building construction, including a frame. A top hook is fixedly connected to the top of the frame, a fixing bolt is threadedly sleeved on the front of the top hook, a hinge is fixedly installed on the top of the frame, and a fixing plate is fixedly connected inside the frame. For this protective net for building construction, by fixedly connecting a reinforcing rib inside the frame to protect the interception net, when the interception net is damaged by the impact of a heavy object, it can prevent personnel from falling from the damaged opening, protecting the safety of building personnel and improving the safety of the protective net. By setting a pressing frame, when the interception net is damaged, only need to unscrew the fastening screws and pick up the pressing frame to replace the interception net, making the replacement of the interception net simple and fast, and ensuring the integrity of the protective net.

[0004] Based on the above, after the existing interception net is fixed, although building materials will no longer fall out of the building, the building materials are easy to slide down along the gap between the interception net and the building. The staff needs to move to the position where the building materials fall before they can retrieve the building materials, which affects the use effect of the interception net.

[0033] The specific usage method and function of this embodiment: First, align the assembling threaded rod 801 with the connecting threaded rod 701, and then rotate the connecting nut 703 so that a part of the connecting nut 703 moves to the outside of the assembling threaded rod 801 to fix the reinforcing traction rope 7 and the positioning traction rope 8 together.
