Installation method of zinc-steel guardrail

Lead: Today, Bunny introduces some knowledge about zinc-steel guardrail. It is no stranger to everyone, but a large number of people are stumped by installing zinc-steel guardrail. Steel guardrail is a very common building material in industry now, which can keep it from rusting for three to five years, but the installation and processing technology of zinc-steel guardrail is also complicated. In the following time, Bunny will explain the installation method of zinc-steel guardrail in detail.

1. For general high-rise buildings, the installation height of zinc-steel railings below 24m is not less than 15mm, and the height of floors above 24m is not less than 11mm;

2. When the railing is vertical, the clear distance between bars should not be greater than 11mm to prevent the head from falling through with the body;

3, the height of the stair handrail should not be less than 9mm; The height of outdoor stair handrails should not be less than 15mm, and the clear distance between bars should not be greater than .11m to prevent the head from falling through with the body;

4. The vertical spacing of protective windows is not more than 99mm;

5. During installation, it will also have a great relationship with the site environment;

6. Installation into the wall: reinforced concrete soil, red bricks can be directly dug into the wall to install shield railings; Hollow bricks, casting blocks need to be processed;

7. Installation in the ground: As above, if there is a plastering layer of 2-3mm, the thickness of plastering layer needs to be deepened. When installing the bracket, it should be punched above the plastering layer to the structural layer;

8. When the expansion screw is buried 3/5 to the structural layer, M6x8 is generally used; We should also pay attention to other common-sense problems in installing shield railings:

9. Metal welding parts are damaged by high-temperature materials, so it needs to be coated with rust-proof zinc, otherwise the corrosion will leave a huge safety hazard;

1. Self-tapping screws are used to connect and install, leaving a huge safety hazard. There are few threads of self-tapping screws, and the pipe wall is thin, and shaking vibration will loosen and fall off, which will lead to the disintegration of the guardrail. Secondly, the self-tapping screws are easy to rust and fall off without any rust prevention measures, and the safety hazard is extremely huge;

11. Draw lines on the completed surface and mark the position of each railing post;

12. Drill a hole in the column with an electric hammer, and the diameter of the drill bit is the same as the diameter of the steel bar of the column; ?

13. Drive the column reinforcement into the borehole with a hammer;

14. Thread the ornamental design into the column reinforcement;

15, put the column reinforcement into the square gap, and then correct the column as a whole and hold it firmly;

16. Play the pheasant line at the top of the column, then draw the line with graphite, and then blow cut the top surface of the column steel bar into pheasant surface with oxygen cutting;

17. Weld the flat iron of the handrail, then heat it with acetylene at the bend and warpage of the flat iron to make it red, and immediately boil water to cool and correct the flat iron. Then weld the corner flat iron, and after the connecting corner flat iron at both ends of the handrail is welded, remove the square wood tied and clamped at the top of the column reinforcement;

18. Welded decorative parts;

19. Install wooden or plastic handrails;

The installation method of zinc-steel guardrail was explained in detail to you above. I believe you have a new understanding of zinc-steel guardrail. For the installation of zinc-steel guardrail, please ask professional workers to install it, so as not to affect the final installation effect. There are various models of zinc-steel guardrail in the market. It is suggested that you must discuss with the merchants what kind of zinc-steel guardrail should be purchased. I will stop here for you about the installation of zinc-steel guardrail.
