Features of the choice of an anchor for various works of
Depending on the conditions under which fasteners will be fastened using anchor devices, several types are distinguished. Proceeding from this, the chemical composition of the product is determined, as well as its shape and design features.
Among the types of anchorages can be identified as follows:
- Frame metal. It is used when it is necessary to fasten wooden frames and other structures to concrete, brick and stone walls.
- Hexagon head. Used for fastening objects with a large weight to concrete, brick or stone.
- With ring. Can be used in installation of structures or construction tour on concrete or brick surfaces.
- Anchor fastening with hook. It is used in the installation of various elements in concrete walls, solid brick or natural stone.
- The nut anchor. It is used for fixing frames and structures on stone, concrete and brick walls.
- Wedge-anchor. It is used for quick installation of frames, scaffolding and other structures on concrete surfaces, for the installation of slats, stretch ceilings, metal products.
- Wedge anchor. Used for the installation of heavy structures on concrete, brick walls and natural stone.
- Clogged anchor. It is used in the installation of structures on concrete, brick and stone surfaces.
- Ceiling anchor. It is used for fastening to the ceiling such products as chains, ropes, cables, suspended ceiling structures, lighting devices.
- Hammered anchor-type dowel-nail. Used for the installation of profiles, as well as various products from thin iron sheets. This type of fasteners is not removable.
- Folding anchor with spring and hook. Used in fixing lightweight structures to plasterboard, wood and to hollow materials.
Wedge anchor: dimensions, markings and characteristics according to GOST
A feature of this type of fastening material is that there is a tail at the end of the anchor, on which, when the article is twisted into the wall, a clutch is found, which causes the structure to expand inside the hole. Therefore, this type of fastening is very reliable and is used in case when particularly heavy structures are to be fixed.
In accordance with GOST, the dimensions of the wedge anchor can vary from 10x100 mm to 8x80.The variety is very large, so you can choose the fastening material for any kind of work. Also in the creation of anchorages can be used various coatings: galvanizing, passaging.
Please note! You can verify the purpose and marking of anchorages according to GOST by the link http: //www.docload.ru/Basesdoc/3/3425/
Each unit is marked according to the type of product, its manufacturer, and also with the size. So the marking of the anchor can be WAM-08060. The letters indicate that it is an anchor wedge driven, and the numbers that the anchor diameter is 8 mm, the thread is 8 mm, the length is 60 mm.
Specification of the
installation The installation of the wedge anchor has a definite sequence that will be described in a step-by-step manner:
Step 1. Drilling the
hole A hole is drilled in the intended installation site with a drill, which should be equal in diameter to the same size of the fastener.
Step 2. Cleaning the surface
After the hole is ready, it is necessary to blow it out and clean it from dust and other by-products of drilling.
Step 3. Installing the bolt
Make sure that in the prepared cavity there are no any types of blockage, you need to place the fastening material in it. This happens by hammering it there with a hammer, similar to a nail.
Step 4. Fastening the anchor in the hole
After the wedge anchor is hammered into the hole, it must be reinforced. This process is carried out by tightening the nut with a wrench. It is necessary to tighten the nut, then unscrew it. After this, the material to be installed must be placed on the bolt, and tighten the nut again until it stops.
As can be seen from the listed steps, in the process of installing the wedge anchor there is nothing difficult. You need to have minimal knowledge and skills in construction.
Important information on working with wedge anchors
When working with wedge anchor fasteners, several important aspects must be considered that can affect the quality of the structure being erected.
- If the fastening is to full-bricks, then fasteners with a diameter of no more than 8 mm can be used. Otherwise, a split brick may occur.
- If you do not have tools for blowing the installation hole at hand, then it must be drilled 15-20 mm more.
- Wedge anchors can not be dismantled. Therefore, if in the future it is planned to dismantle the installed structure, it is necessary, as in the previous paragraph, to drill a hole that exceeds the length of the fastening device. Thus, in the process of eliminating the attached structure, the article will probably drive to the bottom to the bottom.
