Currently, various wooden materials, including timber, are widely used. All kinds of partitions, wall coverings and entire structures are made from it. In order for such structures to serve for a long time, the timber should be fixed with special strong fasteners, and fastening corners are considered the most popular option. Today we will talk about what features they have and what types they are.
What it is?
The corners for attaching the timber are small perforated metal products with equal-sized sides, arranged symmetrically.
The corners have a stiffening rib. They are able to easily withstand even significant weight loads. Such fasteners are used in the construction of structures, which should provide maximum strength, reliability and resistance to deformation.
These parts make it possible to produce even and accurate joining of wooden elements at a certain angle in a given plane . The stiffening rib of the corner for the bar is able to easily withstand heavy loads.
These pieces for joining the beams are most often made from a high quality steel base. The holes that are made in such material are used for fastening bolts, screws and other additional parts.
Angles for fastening can be called versatile fixation options , since building devices and bonding materials are not required to secure them. The connection can be made using screws and nuts or self-tapping screws. Such corners are used for mounting beams and wooden columns.
Currently, in stores, customers can find such fasteners of all kinds and sizes. Due to the wide variety, you can choose the appropriate model for installation work.
Type overview
The corners may vary depending on design features. Today, the most common options for construction work are the following types of metal corners.
- Equal … In this variety, both sides are the same length. Such models are most often used for reliable fastening of wooden parts to each other in those areas where it is imperative to ensure the most even corners. With the help of corners, window and door openings are often formed, slopes are installed, and strong frame structures are created.
- Unequal … Such fasteners for timber are available with sides of different lengths. The values are indicated in the marking. Unequal products are used for the installation of rafters, as well as in the construction of load-bearing roofing.
In addition, iron construction fixtures can differ from each other depending on the strength
- Simple … Such models of fasteners are used in the construction of structures on which excessive loads and pressure will not be exerted during operation.
- Reinforced … These fasteners should be taken when erecting structures, which will be subject to great pressure in the future. In reinforced samples, an additional rib is placed between the sides - this element not only allows you to strengthen the structure, but also makes it the most reliable and durable. Reinforced fasteners are usually made of durable stainless steel with a corrosion-resistant protective coating.
To install such elements, it is recommended to use elongated self-tapping screws with different threads - they will create a stronger connection.
Simple and enhanced varieties metal corners can vary in thickness. For the first, metal up to 2 millimeters thick is most often used, for the second - up to 3 millimeters.
Today, when carrying out various installation work with a bar, metal corners of various configurations are used. Popular options are anchor samples, Z-shaped models, fasteners at an angle of 135 degrees, asymmetric products.
Anchor options have disproportionate dimensions, they differ in different lengths and widths. Such fasteners can have heights ranging from 80 to 200 millimeters.
Asymmetrical models are similar in design to anchor products, but at the same time they have a greater width. Such parts create a right angle with respect to the connection plane.
Variations of the Z-shaped form refer to special reinforced models that are purchased for the installation of building materials placed in different planes. Sometimes they are used to connect bars of various sizes.
135 degree angle fasteners help to create a slope connection. It is this option that should be used in the process of fastening the roof rafters.
Separately, you can also highlight special sliding corners for attaching a bar. They belong to the group of adjustable fasteners. These elements represent a regular corner, consisting of two sides placed at an angle of 90 degrees to each other. In this case, one side of the part is perforated, and the second has the form of an elongated groove.
The second side of such a corner is designed to attach an object and move it in different directions. These fastener models can be produced in different sizes. They will be the best option when creating structures that have offset corners.
Nuances of choice
Before you buy such devices for joining a bar in a specialized store, you must definitely pay attention to some important aspects of the choice. So, you should consider the size of the fastener and the size of the material. Products for timber 100x100, 150x150, 50x50, 100x150, 40x40 are considered standard.
In cases where large wooden elements with a section of 100x100 are used during construction, the mounting angles are selected depending on the width of the material. If you need to fasten the timber to a surface made of concrete, then you should purchase special fasteners with anchor holes.
Take a close look at the surface of the selected building angles … During the production process, they are coated with special protective coatings. The most common are galvanized options.
Such coatings prevent the formation of corrosion on the surface of such products. They make the sample as resistant and durable as possible. Models with a protective zinc coating allow you to form a reliable and durable connection of parts.
You should buy such parts only from trusted well-known manufacturers, since today a large number of low-quality fixing angles are sold, which quickly begin to rust, which leads to wear and the complete destruction of the connection.
Remember that chrome and galvanized options are produced exclusively in the factory, it is almost impossible to fake them.
