[0024] Embodiments of the present application are described below in detail with reference to the accompanying drawings, examples of which are shown in the drawings, wherein the same or similar notations used throughout the drawings indicate the same or similar elements or elements having the same or similar functions. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.
[0025] In this document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variation thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.
[0026] As described in the background, the method of erecting a steel pipe frame with fasteners on the lower end flange of the portal beam to lay a safety net, the specific operation process is usually as follows: first, the steel pipe and fasteners are used to erect on the flange part of the lower end of the portal beam to form a stable support structure; then, the safety net is laid on the steel pipe frame to achieve the purpose of protection. However, this method has the following disadvantages in actual construction process.
[0027] Because this method requires a large amount of steel pipe fastener erection work at a high place, workers face a high safety risk, the construction difficulty is large, and the work efficiency is low. Secondly, because this method needs to use a large amount of steel pipe and fastener materials, the material cost is high. In addition, although the safety net is laid, the protection effect of the safety net alone is not ideal, and the risk of objects falling from a high place cannot be completely avoided.
