Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a scaffolding safety net fixing piece which can be used cyclically. Background Art

[0002] Scaffolding is a kind of peripheral protective facility set up for workers at the construction site. In order to ensure construction safety, after the scaffolding is set up, it is necessary to tie a safety net around the scaffolding. The safety net is mainly used to prevent people or objects from falling and reduce the impact of wind and dust on construction.

[0003] At present, the safety net is generally tied directly to the steel pipe of the scaffolding with steel wire. Although this method has low cost, when tying, because the steel wire can only be tied to a single mesh belt of the safety net, the connection between the safety net and the scaffolding is not strong enough. Therefore, when the external force applied to the safety net is too large, it is easy to directly tear the mesh belt off, causing the safety net to tear, which is not safe enough. At the same time, the use of steel wire for tying also requires the assistance of tools such as wrenches and pliers, which is troublesome to install and easy to prick hands during the tying process. Subsequent workers are also easily injured by the steel wire when working on the scaffolding. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a scaffolding safety net fixing piece which can be used cyclically. The scaffolding safety net fixing piece can fix the safety net on the scaffolding, can effectively prevent the safety net from being torn, makes the safety net more firm, and ensures construction safety.

[0005] In order to solve the above technical problems, the technical solutions adopted are as follows:

[0006] A scaffolding safety net fixing that can be used in a revolving manner, characterized in that it includes a clamping plate and a binding belt; the clamping plate includes a first clamping piece and a second clamping piece, the first clamping piece is provided with a plurality of connecting columns, each connecting column is arranged on the upper surface of the first clamping piece along the up and down direction, and the upper end of each connecting column is provided with a limit block that is smaller at the top and larger at the bottom, and the second clamping piece is provided with a plurality of connecting holes, the number of the connecting holes is the same as the number of the connecting columns and corresponds one to one, the cross-sectional size of the connecting column and the size of the upper end of the limit block are both smaller than the corresponding connecting hole, and the size of the lower end of the limit block is larger than the corresponding connecting hole; the first clamping piece is provided with a first through hole, and the second clamping piece is provided with a second through hole, and the positions of the first through hole and the second through hole correspond to each other; the binding belt passes through the first through hole and the second through hole in sequence.

[0007] When the above-mentioned scaffolding safety net fixing piece is in use, the first clamping piece and the second clamping piece clamp the safety net in the middle and then connect them, and fix the clamping plate on the safety net (usually, the clamping plate is located near the edge of the safety net); then the binding belt is passed through the first perforation and the second perforation in sequence, and then passed around the corresponding steel pipe on the scaffolding and tied, so that the safety net is connected to the scaffolding through the clamping plate and the binding belt. When fixing the same safety net, multiple scaffolding safety net fixing pieces can be used to fix the safety net on the steel pipe at multiple positions near its edge, thereby realizing the overall fixation of the safety net. No auxiliary tools such as wrenches and pliers are required during installation, which is both labor-saving and efficient.

[0008] The connection method of the clamping plate and the safety net is as follows: each connection column on the first clamping piece is passed through the mesh of the safety net respectively, and then each connection hole of the second clamping piece is aligned with the limit blocks on the upper end of each connection column, and the second clamping piece is pressed down with force, so that each limit block passes through the corresponding connection hole respectively, and the connection column is in the corresponding connection hole, and the connection can be completed; after the connection is completed, under the action of each limit block, the first clamping piece will not be separated from the second clamping piece. With this structure, not only is the installation and connection simple, but also each first connection column can be respectively inserted into different mesh holes of the safety net. When the clamping plate is subjected to force, the force it receives can be dispersed to different mesh belts on the safety net through each first connection column, thereby improving the tensile strength, and there will be no situation where a single mesh belt is subjected to excessive force, which can effectively avoid the tearing of the safety net, making the safety net more solid and ensuring construction safety. When it needs to be dismantled, the safety net and each clamping plate can be removed from the scaffolding by simply cutting the binding belt, and the clamping plate can be reused.

[0011] In another preferred embodiment, some of the connecting columns are cylindrical, some of the connecting columns are prismatic, and the limiting blocks are in the shape of a cone, a truncated cone, a hemisphere, a pyramid or a prism that is small at the top and large at the bottom.

[0012] In a preferred embodiment, the first clamping piece and the second clamping piece are both circular. The first clamping piece and the second clamping piece are circular, so that the edges are smooth and not sharp, and will not accidentally injure workers or scratch the safety net.

[0013] The clamping plate is usually made of tough and wear-resistant plastic, which can effectively ensure strength. In the preferred embodiment, the clamping plate is made of nylon, polyethylene, polyurethane (PU) orPolyetheretherketone (PEEK).

[0014] In a preferred embodiment, the tie strap is a self-locking tie strap. More preferably, the tie strap is a self-locking nylon tie strap. The tail of the self-locking tie strap is passed through the first through hole and the second through hole in sequence, and then passed around the corresponding steel pipe on the scaffolding.
