the notation in the figures means: 1-steel purlin; 2-concrete wall body; 3-angle steel; 4-connecting bolts; 5-hooking; 6-turnbuckle; 7-U-shaped hook; 8-a steel support structure; 9-safety hook.
Detailed Description
The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
After the concrete wall 2 is built, the steel purlin 1 is fixedly connected with the concrete wall 2, and the steel supporting structure 8 is fixedly connected with the steel purlin 1. The utility model discloses steel shotcrete prevents that mechanism of falling encloses purlin 1 and steel bearing structure 8 with the steel respectively and is connected with concrete wall 2, prevents that the steel construction from taking place to fall.
As shown in figure 1, the anti-falling mechanism for steel support of the utility model comprises angle steel 3, connecting bolt 4, hook 5, turn buckle 6 and U-shaped hook 7 which are connected in sequence.
One end of the angle steel 3 is fixed on the concrete wall 2 through a connecting bolt 4. The connecting bolts 4 are expansion bolts, so that the connecting strength of the bolts and the wall body is enhanced. The other end of the angle steel 3 is connected with one end of a hook 5, and the other end of the hook 5 is connected with one end of a ring on the turn buckle 6.
