Dowel for aerated concrete: modern types of fasteners for

Installing fasteners in porous building materials has always been a big problem. There were no such screws, anchors or nails that could reliably hold even a small object on the wall. The base just crumbled while driving in or screwing in fasteners.

But experts have found a way out. A metal dowel for aerated concrete and its plastic analogs were invented.

Now you can work with any capricious materials, without fear of their destruction.

Features of fasteners for porous materials

Cellular materials such as aerated concrete and foam concrete are available, convenient and practical to use. Therefore, today they are in high demand.

Note! But the joy of even neat walls and partitions can be overshadowed by problems with their further decoration and decoration. If you yourself decided to hang a photo in a frame, shelves or a hanger, conventional screws for concrete will not help you.

Application areas for special dowels

1. Using special dowels it is recommended to attach frame elements to the walls for further wall cladding.. Finishing, for example, drywall walls and ceilings requires durable and reliable profiles. The modern dowel on a gas concrete will come to the rescue, it is simply mounted and firmly holds the elements in the concrete.
2. The door frame or window without a good fixture also does not install. And here it is necessary to resort to specially designed supplements.
3. Even trifles such as lamps, switches and sockets to mount with conventional screws also do not work. They just fall out, leaving a hole in the wall.
4. Only the screwed-in dowel in aerated concrete can firmly fix the moldings, plinths or trim on the wall, moreover, a special configuration.
5. TV, poster, pots, picture, cornice and other accessories will have to hang only on a special element. Otherwise, things dear to the heart and pocket will be overwhelmed.

Design features

Dowels are made of metal (brass, stainless steel, alloys) and plastic (polypropylene, nylon). Some species need to be screwed, there are hammered species.

That is what the device consists of.

1. A metal tube, at the end of which there are four petals with a serrated surface. Inside the aerated concrete petals expand, providing a perfectly strong grip with the base.
2. Actually dowel, screwed or clogged in the cuff. It is threaded or has a difference in diameter. Going inside the tube, the thread or the thickening is bursting it, forcing it to fix securely in the wall.

Product cost

Depending on the purpose and material of manufacture, as well as the design varies and the price of fixtures.

1. Plastic devices cost from 30 kopecks apiece.
2. Dowels made of metal more expensive - from 2.8 rubles apiece.
3. Nylon counterparts - from 3 rubles / pcs.
4. Polypropylene fasteners with stubs will cost 2.8 / 3 rubles / pcs.

There are more expensive, branded accessories from import manufacturers. Their cost comes to 32, 53 66 rub. / Piece. for diameters of 8, 10 and 14 mm, respectively.

Tools for installing dowels

For high-quality and proper installation of fasteners, the manual recommends acquiring the necessary tools.

1. Drill or drill with a set of drills for concrete.
2. Screwdriver with cross cut.
3. Hammer.
4. Roulette, pencil.

If you have invited experts conducting diamond drilling holes in concrete, it is possible to ask them to help you with the installation of dowels. Those who like to work independently can be advised to hire a drill if there is no need to purchase it.

Mounting mounting

1. The hole for the dowel should be slightly less than its diameter. For example, for an 8 mm fastener, you should take a 7 mm drill bit.
2. When using a hammer drill, turn off the blow function. If you can make a choice in favor of the drill, it is in our case more efficient.
3. Plastic fasteners carefully screw in with a screwdriver. Metallic analog is better to hammer in the mounting hole.
4. When working, make sure that there are no distortions and swinging of the product.
5. After the cuff is inserted all the way, a self-tapping screw or universal bolt can be screwed in.
6. Using a screwdriver, screw the screw to the desired depth (up to the stop or leaving a part outside).

Note! Do not use a screwdriver, as an electric device is difficult to control. He can twist the screw and knock down the thread. It is better to work as an ordinary screwdriver.

Professional Tips

1. If you have aerated concrete walls, it is not necessary to involve expensive labor with special equipment. For example, high-tech cutting of reinforced concrete with diamond circles is not at all necessary here, and resolutely reject intrusive construction services. Your material is perfectly sawn with a regular hand saw and drilled with a simple electric drill.
2. Those who do not want or can not buy industrial dowels, you can advise the following - to make home-made fasteners. Chopiki (wooden sticks) with a sharpened end are punctured. A chopik is hammered into the prepared hole of a slightly smaller diameter. Further, a screw is screwed into it.
3. The drilled hole should be slightly longer than the dowel. When driving, the fastener will push dust and particles of concrete into the back. Therefore, the bottom of the hole is made deeper "in reserve".
4. Do not buy for small things (photos, small paintings, hooks, etc.) too powerful dowels. Plastic fasteners for 8 mm are quite suitable. Even he, with proper installation, can withstand a considerable weight of the subject.

Conclusion

Do not be afraid of finishing porous bases. Today there is an opportunity to purchase cheap and effective fasteners, for example, a plastic dowel for aerated concrete, already tested and approved by users.
