Rafters and plates for their fastening
Rails are often in the form of a triangle, but there are other shapes. If necessary, use the attic systems to save space. Their special structure makes it possible to make an additional room. Fasteners for rafters are designed to connect the elements of the roof system. It includes: perforated and nail plates, corners, sliding supports, rafters, beam supports, beam supports, etc.
Each kind of these devices is manufactured in several sizes, so you can choose it for any parameters. It is made of perforated steel sheets with a thickness of 1.5-3 mm, which is galvanized for protection against corrosion.
rafter fastening plates contain holes for screws and bolts. With their help, a strong connection of two or more elements is obtained at any angle in one plane. They are superimposed on the connection from both sides. If necessary, they can be cut to the desired shape.
Nail plates have several rows of nails on one base. Used in the same way as conventional perforated plates, only with the difference that they need installation in industrial conditions. Fastening is done by pressing using a press. They can not be hammered, because then there will not be a reliable connection.
When do you need a secure mount?
A rafter and beam fastener connects perpendicular structural elements that are supported by one another, and can also serve to hem the transverse parts on the underside of the beams. For reliability, a pair of fixtures are made asymmetrically, unfolding one in the other direction.
Sliding fastening is used for the construction of buildings from logs or logs, if it is necessary to make inclined rafters. Then the distance between the ridge run and the Mauerlate changes because of the shrinkage of the log, so you can not fix the fixed parts. Skidding for rafters allow the offset along the lower edge of the rafters relative to the wall.
The beam supports help to fix the bearing horizontal elements at right angles to other parts of the structure. You can use nails, bolts and screws for fastening to the main support. Supports of the beams are made in different sizes so that they can be selected for different height and width of the beams.
Hidden beam bracket is used for invisible mounting. After installation, it completely hides in the body of the beam. At the end of the beam a vertical cut is sawed, and holes for the pins are drilled. This bracket is mounted to the bearing part of the structure, where a place is chosen for the thickness of the metal, then a beam is put on it, and the pins are inserted.
Fastening and repair of rafters - we raise building erudition
Angles for fastening of rafters fasten at a right angle building elements. They have holes for self-tapping screws or nails. They often connect horizontal elements with vertical stands.
There are also angles with elongated holes that are suitable for bolts. Thanks to them, then you can adjust the position of the parts relative to each other. In addition, there are also corners with bent parts and an angle of 135º.With their help, it is possible to join parts of structures from different angles.
T-shaped fastening is intended for interconnection of two perpendicular elements. Brackets for rafters are used to fasten rafters.
Further we learn, that such a crutch for fastening of rafters and for what it is used. This element with a ridiculous name is useful for repairing rotted parts of rafter feet. He is hammered into the masonry, and then the beam is laid on it.
Fastening of rafters with of perforated fasteners provides reliable connection and installation of wooden structures, and significantly speeds up the work process.
