Those who have ever tried to fix the screw in concrete, using standard plugs, you know how it is fragile. And in the brickwork, sometimes not so easy to do this, as it would seem. Tightened some object against the wall, and after a while he fell you, anchors from the wall jumped out!
In this article we will focus on how easy it is, without any special hardware.
One of the most commonly used dowel is a dowel with a diameter of 6 Th. It is generally screwed into screw having a diameter of 3.5 mm or 4.2 mm.
This combination is not reliable for the aerated concrete, or rather quite unreliable.
There are also universal plugs, they are a bit longer. Executed in orange.
And what do you think, is there a way out?
In my opinion there is a solution and it is quite simple. I'm just in the dowel screws are screwed into a larger diameter.
For example, a 6-mm plugs you need to twist the screws diameter 4 mm 2, I'm against all the rules Screwing 5 mm screws.
Even as a way out of this situation, you can use a universal plug, as I wrote earlier it is longer than the standard.
When using a longer dowel and the area of its coupling with gas concretes will be greater, respectively, and hold it in it will be better.
You can also use wooden plugs, and better their drive just two. In this situation, the same area of adhesion plugs with concrete, will also be increased. Stay will be much stronger.
Well, in the cork screw the screws more than necessary diameter. From this action fastening strength only increase.
As the saying goes "Porridge oil will not spoil!" Do not believe me, check and make sure my right.
The next option to increase grip area is enlarged in diameter dowel and screw increased.
What would you get out in the concrete, I was at least 8-ku use. More next drive in the plug and screw 6 mm spins.
And yet, the right to drill holes for dowels puncher, but off hammering. Simple drilling drill pobeditovym best option.
In this case, aerated concrete to collapse on the inner sides of the holes will be.
Not too much PVA glue and use. Drill a hole for the dowel, it was poured into PVA glue and hammer dowel screw the screw. PVA will paste plug to the aerated concrete, and it will hold firmly.
Here are simple tips. If you are using them, your furniture will be mounted to hang forever.
No force can not pull out the plug from the aerated concrete.
