[0016] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. The embodiments described are exemplary and intended to be used to explain the present application, but should not be construed as limiting the present application.

[0017] Reference Figure 1 and Figure 2 , a straight thread sleeve connection type steel bar edge protection, including vertical protective steel bars 1, nuts 2, footboard fixings 3, transverse protective steel bars 4, straight threaded steel bar embedded parts 5, straight threaded sleeves 6, footboards 7 and dense mesh safety nets (not shown in the figure); the bottom end of the vertical protective steel bar 1 is processed with straight threads, the nut 2 is welded to the vertical protective steel bar 1, and the footboard fixings 3 are welded to the bottom of the vertical protective steel bar 1 to form a steel bar edge protection body; the straight threaded steel bar embedded parts 5 are fixed to the floor steel bars, and the straight threaded steel bar embedded parts 5 are connected to the steel bar edge protection body through straight threaded sleeves 6, the transverse protective steel bars 4 are inserted and connected to the nut 2 of the steel bar edge protection body, the footboard 7 is inserted and installed in the footboard fixings 3 of the steel bar edge protection body, and the dense mesh safety net is fixed to the sides of the vertical protective steel bars 1 and the transverse protective steel bars 4.

[0018] In this embodiment, the straight threaded steel bar embedded parts 5 are fixed to the floor slab steel bars by welding or other fixing methods before pouring concrete.

[0019] In this embodiment, there are two nuts 2, which are welded to the middle and top of the vertical protective steel bar 1 respectively.

[0020] In this embodiment, the footboard fixing member 3 is a U-shaped member, the opening of the U-shaped member faces the vertical protective steel bar 1, and is welded and fixed to the vertical protective steel bar 1 at the top of the U-shaped member.

[0021] In this embodiment, the dense mesh safety net is fully hung on the sides of the vertical protective steel bars 1 and the horizontal protective steel bars 4, and is tied and fixed with galvanized iron wire.

[0022] The construction method of the straight thread sleeve connection type steel bar edge protection includes the following processes: making straight thread steel bar embedded parts 5 → making steel bar edge protection main body → installing embedded straight thread steel bar embedded parts 5 → installing steel bar edge protection main body → installing transverse protection steel bars 4 → installing footboards 7 → fully hanging dense mesh safety nets.

[0023] The specific steps include:

[0024] 1) Use HRB400 steel bars with a diameter of 25 mm to make a single vertical protective steel bar 1 with a length of 1150 mm, and process a straight thread at the bottom with a thread length of 35 mm.

[0025] 2) Weld two nuts 2 at 650mm and 1150mm from the bottom of the vertical protective reinforcement 1 respectively.

[0026] 3) Use HRB400 steel bars with a diameter of 8mm to make a U-shaped piece with a height of 200mm and a width of 20mm. The opening of the U-shaped piece faces the vertical protective steel bar 1, and the top of the U-shaped piece is welded and fixed to the vertical protective steel bar at a height of 150mm.
