Today in construction materials such as foam concrete block and aerated concrete are increasingly found. They are very easy to process, and have high thermal insulation characteristics. However, they have one feature. In order to securely attach various structures to these materials, special fasteners are required.
In this article, the author of the YouTube channel "StoDel_56" will tell you how you can make a reliable connection in a classic way.
Materials
- Pine slats
- Screw bolt for wood M10.
Instruments, used by the author.
— Screwdriverwrench
- Feather drills for wood
- Hacksaw, hammer, knife, pencil.
Manufacturing process.
The author has the task of attaching staircase structures to such a wall, and this is a very responsible task.
He will show the method of fastening on the example of a pillar for the railing. First, an opening for the bolt and its head is prepared in the upper part of the rack. Marking is also applied on the wall, and a hole with a diameter of 8 mm is planned in it.
Next, you need to cut from a pine lath 20X20 mm such workpieces with a length of 100 mm.
The next step is to cut in the back of the chopik a third of its length. This can be done with a hacksaw, or with an electric jigsaw. It is not recommended to do a cut for a long length, otherwise the wood may crack when wedged. Bevels are also carried out at the edges.
These bevels will be needed for the reason that the chopper will then drive into the wall, in which a round hole will be drilled with a pen drill with a diameter of 20 mm, and the corners on the chopper will interfere. The length of the workpieces must be selected depending on how deeply you can drill a hole in the wall.
So, the marking is ready, and you can drill a hole.
Chopik is easily hammered right into the wall, and his rectangular faces will not let him turn.
Now the hole in the chopper itself is marked and drilled. It should be 8 mm in diameter when using the M10 bolt (according to the diameter of its body). You should also check the depth of this hole, its edge should end near the beginning of the cut.
It remains only to tighten the screw-bolt itself on the tree. The twisting force is very large, especially at the very end, when the bolt will open the wedge. For this reason, it is advisable to use a wrench.
The author also focuses on the fact that the fixed part can be removed by simply unscrewing the bolt, while the chopstick itself remains intact. With some types of chemical anchors, this is no longer possible.
I thank the author for a simple but very reliable way of attaching structures to foam blocks.
All good mood, good luck, and interesting ideas!
