[0002] Building construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction.

[0003] In roof construction, many projects involve parapet walls, especially those with low parapets, posing a significant safety risk to workers. During the early stages of main structure construction, scaffolding exists, allowing for various methods of perimeter protection around the roof. However, in later stages, due to construction sequence limitations, the scaffolding must be dismantled beforehand. Therefore, during roof construction, only temporary steel pipe protection can be erected around the roof perimeter. Consequently, ground-mounted protective measures are frequently forced to be dismantled or relocated due to construction needs, resulting in safety hazards, operational inconvenience, and low work efficiency.

[0004] Therefore, it is desirable to provide an edge protection device during the construction of roof projects with parapet walls that is easy to use, securely fixed, reduces the risk factor for workers, does not affect other construction processes, and can be reused. Utility Model Content

[0047] 2. After the concrete pouring of the parapet wall 15 is completed and the formwork 16 and fixing bolts 17 are removed, determine whether an extension rod 13 is needed based on the structure of the parapet wall 15.

[0048] 3. If the extension rod 13 is not required, screw the first connector 3, which is connected to the steel pipe connector 4, into the first screw hole 5, as follows.

After the concrete of the parapet wall is poured and the formwork is removed, the steel pipe connector can be directly connected to the embedded rod through the first connector and the first screw hole. Then, after adjusting the direction of the steel pipe connector, the vertical steel pipe can be detached and connected. The vertical steel pipe is used as a vertical protective support. After the construction of the vertical protective support is completed, the horizontal steel pipe is connected to complete the roof protection facility. If there is an eave in part of the parapet wall, an extension rod can be added between the steel pipe connector and the embedded rod. Specifically, the extension rod is first connected to the embedded rod through the second connector and the first screw hole, and then the steel pipe connector is connected to the extension rod through the first connector and the second screw hole.
