[0023] Reference Figure 1-5 This utility model discloses a fall arrest device for steel structure construction, comprising: a channel steel frame 1, a connecting plate 3 fixedly connected to the bottom of the channel steel frame 1, a connecting frame 7 fixedly connected below the connecting plate 3, a connecting plate 13 fixedly connected to one side of the inner part of the connecting frame 7, a steel wire 6 disposed below the connecting plate 13, and bolts 14 connected to the steel wire 6 and the connecting plate 13; a slot is opened in the middle of one side of the connecting frame 7, a roller 12 is disposed in the slot, a connecting rod 10 is fixedly connected to one end of the roller 12, and a partition plate 11 is fixedly connected to the side of the connecting frame 7 near the connecting rod 10. The plate 11 and the connecting frame 7 are both provided with connecting holes on the side walls parallel to the partition 11. The steel wire 6 bends upward and passes through the inner side wall of the partition 11 and the adjacent connecting frame 7. Specifically, the steel pipe is placed inside the steel wire 6, and the steel wire 6 is inserted upward into the connecting frame 7. The electric drill clamps the connecting rod 10, and the electric drill drives the connecting rod 10, thereby driving the roller 12 to roll, so that the steel wire 6 passes through to the top of the connecting frame 7. That is, the roller 12 drives the steel wire 6 to move upward, so that the steel wire 6 fits the outside of the steel pipe to the maximum extent and is in a taut state. After the roller 12 is used, it is separated from the connecting frame 7 and removed.
[0024] The connecting frame 7 has a long slot on one side of the roller 12. The connecting rod 10 is located inside the long slot, and the end away from the roller 12 is located outside the long slot. Specifically, the electric drill clamps the connecting rod 10 located outside the roller 12.
[0025] Bolt 5 is provided on the connecting frame 7. Bolt 5 passes through the steel wire 6, the partition 11 and the side wall of the connecting frame 7 and extends to the outside of the connecting frame 7. Specifically, after the steel wire 6 passes through to the top of the connecting frame 7, bolt 5 is passed through the connecting hole of the steel wire 6, the partition 11 and the side wall of the connecting frame 7.
[0026] The channel steel frame 1 is provided with multiple through holes 2. The axial direction of the through holes 2 is perpendicular to the connecting frame 7. Specifically, expansion bolts are driven into the through holes 2 to fix the channel steel frame 1 to the wall.
[0027] On both sides of the bottom of the connecting plate 13, there are two fixing frames 14 and 29 respectively. There are two fixing frames 14 and 29 respectively. Both fixing frames 14 and 29 are triangular in shape and fixed to the connecting frame 7. Specifically, the connecting plate 13 is used to connect the channel steel frame 1 and the connecting frame 7. The two fixing frames 14 and two fixing frames 29 are used to reinforce and fix the stability between the connecting plate 13 and the connecting frame 7.
[0028] Connecting plate 3 and connecting bracket 7 are connected by bolt 8.
[0029] Bolt 1 (5), Bolt 2 (8), and Bolt 3 (14) all have nuts threaded on the other side.
[0030] Working principle: Drive the expansion bolt into the through hole 2 to fix the channel steel frame 1 to the wall. Place the steel pipe inside the steel wire 6 and pass the steel wire 6 upward into the connecting frame 7. The electric drill clamps the connecting rod 10 located outside the roller 12. The electric drill drives the connecting rod 10, thereby driving the roller 12 to roll. Pass the steel wire 6 through to the top of the connecting frame 7. Pass the bolt 5 through the connecting hole of the steel wire 6, the partition 11 and the side wall of the connecting frame 7. The nut cooperates with the bolt 5 to firmly fix the steel pipe inside the steel wire 6.
