The rapid development of building technologiesentails the development and creation of not only the latest materials, but also the introduction of various mounting systems. Dowel is widely used among these fasteners. This is a special element used for fasteners of various designs. The industry produces a lot of different types of dowels for solving a huge number of tasks. Consider what it is, as well as the main types of these products.
The dowel is a fastener thatdesigned for installation and connection works. Now the industry produces a huge number of types of these elements. Each type is suitable for a particular material. There are products for concrete, metal or wood, as well as drywall constructions.
This fastener is used when access tothe edge of the rod for the connection is difficult or impossible. For example, you need to make a hole in the wall to install the cabinet in the kitchen or shelves in the room - for this, you need a dowel. The dowel is also an ideal choice when the wall is hollow or has voids in it. Any other fasteners and systems will simply be ineffective.
This fastener in appearance isa cylindrical rod. If we talk about materials, it is nylon, polypropylene, metal, polyethylene. The industry also produces metal anchors.
The product consists of two parts.The first is a spacer. It will be expanded during installation, due to which the fasteners will be reliable. The second part is unsuccessful. Individual products have special cuffs. They prevent the dowel from falling into the hole.
В строительных магазинах представлен широкий selection of a variety of products. But you need to understand that each of them is suitable for solving specific problems. There are several types of these elements:
These are the most simple dowels, but they are likea huge part of the fixing work. These elements can be selected when working with stone, concrete walls, bricks. In the process of screwing the screw, the plastic dowel will be wound on the metal, thereby strengthening the mount.
This is also a polypropylene product. However, its feature is in the presence of struts.
These parts are specially designed and manufactured.for fasteners in plasterboard or gypsum-fiber walls. If you need to install something in porous concrete, then choose this option. These fasteners are made of metal or plastic.
These items are made of nylon. You can use them for almost any task. They are ideal for all surfaces.
These types of expansion dowels are designed for serious mounting work.
This product is intended for fastening the batten for plating.
The main feature of these parts in the possibility of adjusting the position of the elements relative to the base, to which the fastener.
These are special types of dowels, and their use is alsospecial. They are not used in most fasteners, and are intended only for the installation of thermal insulation materials made of mineral wool or polystyrene. In appearance, the detail really resembles an umbrella - so, there is a wide round cap. It is necessary for keeping insulation.
По внешнему виду данная крепежная деталь is a loop. Make these products from plastic. These clamps are designed for installation work on electrical wiring. The use of these dowels is very simple. First, a hole is made at the base of the required diameter, then the wire is pressed against the clamp.
These parts are made of metal - usetheir specific enough. They are designed to install window and door frames. But there are other tasks that help solve these types of dowels.
This is one type of ordinary dowel.The difference in the possibilities of quick installation is enough to hammer it into the wall. This product is widely used in repairs. With them, you can quickly and reliably fix the baseboards, lighting fixtures on the ceiling, any materials to any bases.
The use of dowel-nails makes it easy to perform fasteners to concrete, wood or brick wall.
Основные составляющие гвоздя – это саморез с carving, which is narrowed in the direction of the sharp part. This feature makes it possible to work with these elements not only with the help of a screwdriver or a drill. It is allowed to use a hammer and plastic dowels.
The main difference of this type of fasteners fromother types in that the main part works on the principle of nail, and not screws. But some elements that are produced by modern industry may have a slotted crosshead screwdriver on the head. But twist them with a screwdriver - for quite some time. The most effective is to use a hammer.
Plastic part in the process of drivingexpands, thereby providing a reliable and, most importantly, durable fastening. The dowel on one of the edges has a special cuff. It does not allow the element to completely go into the hole. The shape of the cuff may be different.
An important point is the technical specifications.The main parameters are the length and diameter of the nail. Take a standard dowel-nail. Sizes and types - from 40 to 140 mm in length, the step is equal to 20 mm. Diameter - from 5 to 7 mm. To work with these fasteners, the hole diameter for them is from 6 to 10 mm. Conventionally, the fastener model is designated by two indicators. This is the diameter of the hole as well as the length.
The dowel fixture provides useself-tapping screws. There are several types of these products according to the material in which they will be screwed. The industry produces self-tapping screws for wood, metal, products with a press washer, self-tapping screws with a drill, for concrete, brick and stone. The product for wood has a rare thread pitch. So, here the distance between the coils is greater than that of metal products. This is because the wood is less dense and hard. These items can be black, gold and white. The choice of color depends on what you need to work with. Most often with dowels apply black and golden element.
Types of screws and dowels are different in length. So, the length of the black screws - from 11 mm to 200 mm. As for the diameter, blacks start from 3.5 to 4.2 mm. Yellow diameters - 2.5-6 mm.
When selecting a dowel, its shape is only onefactor that is usually oriented. About others forget, but in vain. It is important to know which size to choose. For example, a dowel 6 x 40 is suitable for work on the installation of various shaped structures in the walls of cinder block. Another size will not work - the product will just fall out of the hole.
When selecting the length of the part, you must rememberloads that the fastener will experience. The shorter the dowel and screw, the less load it will endure. In addition, the diameter is very important. For ordinary household work fit parts with a diameter of 8 to 10 millimeters. The difference in the depth of the hole affects the maximum load.
The main rule when working with this type of fasteners- the drill diameter must match the number or size of the dowel. In an ideal situation, the plastic or metal element should hardly enter the hole. As for the material of the drills, for concrete, experienced experts recommend choosing the best tool. It is enough to solve most construction problems. Acquire more expensive drill does not make much sense.
