[0032] Of course, in other alternative embodiments, the number of mounting holes 11 , the number of fixing rods 20 , and the number of fastening assemblies 30 may also be adjusted according to actual conditions.

[0033] Specifically, the fixing rod 20 in this embodiment is a wall-penetrating screw.

[0034] It should be noted that, during the construction of the structural beam 70 , it is necessary to pre-embed a PVC sleeve in the structural beam 70 to form a reserved hole for the fixing rod 20 to pass through the beam.

[0035] In one embodiment, Figure 1 As shown, the external scaffolding tie point further includes a fastener 50 , which is suitable for connecting the tie rod 40 and the vertical rod 80 .

[0036] In one embodiment, Figure 3 As shown, the fastener 50 includes a connecting portion 51 and a main body portion 52. Two main body portions 52 are provided. The two main body portions 52 are arranged at intervals, and the first ends of the two main body portions 52 are respectively connected to the two ends of the connecting portion 51 to form a first mounting groove. The first mounting groove is suitable for setting the vertical rod 80. The main body portion 52 is formed with a second mounting groove, and the tie rod 40 passes through the second mounting grooves of the two main body portions 52.

[0037] For details, please refer to Figure 3 The main body 52 is a U-shaped rod with a second mounting groove formed inside the U-shaped rod. The connecting portion 51 also forms a U-shaped rod structure after being connected to the first ends of the two main bodies 52, thereby forming a first mounting groove. The groove directions of the first mounting groove and the second mounting groove are perpendicular, that is, the axial direction of the tie rod 40 is perpendicular to the axial direction of the vertical rod 80.

[0038] Of course, in other alternative implementations, the directions of the openings of the first mounting groove and the second mounting groove may also be at other angles.

[0039] In one embodiment, Figure 3 As shown, the fastener 50 further includes a mounting plate 53 , which is connected to the second ends of the two main body portions 52 .

[0040] In one embodiment, the tie rod 40 is connected to the base 10 by welding.

[0041] It is worth noting that the tie rod 40 is welded to the base 10 to obtain a higher connection strength and improve the overall structural strength.

[0042] In other alternative embodiments, the tie rod 40 is detachably connected to the base 10 .

[0043] It is worth noting that the tie rod 40 and the base 10 are detachably connected, and after the external scaffolding tie point is used, the tie rod 40 and the base 10 can be disassembled and reassembled for use.

[0044] In one embodiment, Figure 1 As shown, the external scaffolding tie point further includes a reinforcing rib 60 , which connects the tie rod 40 and the base 10 .

[0045] Specifically, in this embodiment, the reinforcing rib 60 is connected to the tie rod 40 and the base 10 by welding.

[0046] Of course, in other alternative embodiments, the reinforcing rib 60 may also be connected to the tie rod 40 and the base 10 in a detachable connection manner, such as threaded connection.

[0047] It is worth noting that, by providing the reinforcing ribs 60 , the connection strength between the tie rod 40 and the base 10 is improved, and the stability of the tie point structure of the external scaffolding is improved.

[0048] In one embodiment, Figure 1 As shown, a plurality of reinforcing ribs 60 are provided, and the plurality of reinforcing ribs 60 are arranged at intervals.

[0049] Specifically, four reinforcing ribs 60 are provided, and the four reinforcing ribs 60 are arranged at intervals along the circumference of the tie rod 40 .

[0050] Of course, in other alternative embodiments, the number of reinforcing ribs 60 can also be selected according to actual conditions, such as three, five, etc.

[0051] It is worth noting that by providing a plurality of reinforcing ribs 60 , the connection strength between the tie rod 40 and the base 10 is further improved.

[0052] In one embodiment, Figure 1 and Figure 2 As shown, the tie rod 40 is spaced apart from the mounting hole 11 .

[0053] In one embodiment, Figure 2 As shown, the fastening assembly 30 includes a nut 31 and a washer 32 . The washer 32 is disposed on a side of the nut 31 close to the base 10 . The nut 31 is threadedly connected to the fixing rod 20 .

[0054] Specifically, the nut 31 is selected as a common flat-angle nut 31 , and the washer 32 is selected as a steel washer 32 .

[0055] It should be noted that in other alternative embodiments, the fastening assembly 30 may also use the nut 31 alone. However, the use of the washer 32 improves the fastening effect of the nut 31. Therefore, in order to improve the locking stability of the fastening assembly 30, the nut 31 and the washer 32 are selected to be used simultaneously.

[0056] In an optional embodiment, a plurality of nuts 31 are provided, and the plurality of nuts 31 are connected to the fixing rod 20 in sequence.

[0057] It should be noted that a plurality of nuts 31 are stacked in sequence, and the locking capabilities of the plurality of nuts 31 are utilized to ensure that the innermost nut 31 is in a stable locking state.

[0058] It is worth noting that by stacking a plurality of nuts 31 in sequence and connecting them to the fixing rod 20 , the fixing stability of the nuts 31 is improved, and the safety performance of the fastening assembly 30 is improved.

[0059] Of course, in other alternative embodiments, a self-locking nut 31 may also be used, and the self-locking nut 31 may ensure a stable locking state through its self-locking performance.

[0060] It should be noted that the self-locking nut 31 loses its self-locking ability when it is loosened after being tightened, so the cost of using the self-locking nut 31 is relatively high, while the ordinary flat-angle nut 31 can be used multiple times, thereby achieving the effect of cost saving.

[0061] To apply the external scaffolding tie points of this embodiment, first, a hole is reserved on the structural beam 70 for the fixing rod 20 to pass through the beam; then, one end of the tie rod 40 is welded to the base 10, and four reinforcing ribs 60 are welded to the connection between the base 10 and the tie rod 40; thereafter, the fixing rod 20 is passed through the reserved hole, and the base 10 is fixed to one side of the structural beam 70 by using the nut 31 and the gasket 32, and the nut 31 and the gasket 32 ​​are also tightened on the other side of the structural beam 70; finally, the tie rod 40 is connected to the vertical pole 80 by the fastener 50.

[0062] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
