Bar fasteners: types and applications

In working with wood, timber, log, beams, there is always a need for additional means of fastening. This may be a fastener for a timber 100x100, or another section, but the main thing is that the connection today is represented by an extensive ruler in which you can choose the most suitable fastener.

Consider all types of fasteners, as well as areas of use.

Perforated version

This is the most common fastener timber, which is used in almost any construction work. They are used to connect the console carrier beam ceiling, timber. There are a lot of options for perforated products, and in each individual case, it fits a certain type of work.

Corner

The easiest and inexpensive type of attachment. The instruction assumes that it can be used not only strictly in assembling a house, but also in working with furniture and staircase structures. It allows you to arrange an angle of 90 degrees between the two elements of the structure.

The design of the corner has holes of various diameters, from 55 mm to 14 mm, which allows the use of screws, bolts, screws of a certain section for fastening a bar.

Note! The corner fastening of the beam is made in many ways, and the perforated fastener in this case acts as an additional reinforcement for the corner fastening.

What else should be noted, these fasteners for timber, as well as other perforated products, are made of galvanized steel, which has high rates of not only strength, but also ductility. The hot-dip galvanizing method gives the mount not only an aesthetically pleasing appearance, but also helps protect the metal from corrosion.

You can determine the main advantages of the corner:

• Easy to install. No need to use special tools.
• Reliability, which is ensured in the simplest way, by a screw or a nail!
• No need for mandatory tie-ins, which instantly increases the ease of installation and strength of the entire structure.

Corner усиленный

Unlike the simple version, here is used stiffener. This moment allows not only to increase the strength and reliability of the connection, but also to increase the service life. In addition, it is worth noting that the corner with a stiffener is ideal for external work, it can be used in difficult climatic conditions.

It is made of cold carbon galvanized steel, two, two and a half millimeters thick. As a rule, they are fastening the timber at a right angle to the plane.

Beam holder

The metal holder of the beam is a fastener, which is used in the installation of timber in the work with the roof and wooden floors.

In addition, it can be used in:

• Fastening structural bearing beams.
• Installation of ceiling ceilings, interfloor ceilings.
• Installation of floors.
• In the assembly of any wooden structures, when there is a need to form the basis for the carrier part.

The thickness of the product is 2, -2.5 mm, steel is covered with zinc, which gives anti-corrosion protection. In the work, you can use screws for wood or nails, holes in steel allow it. In addition, this method of installation allows rapid installation, without special tools or skills.

Support for timber

This type of attachment can be open and closed.

The open type is suitable for:

• Installation of floor beams.
• Creation of connecting nodes in the truss system.
• Installation of an open support not only to wood, but also to a concrete, brick surface.

Perforated holes with a diameter of 5.9.11 mm are provided in the support. As a means of connection, you can use screws and nails for wood, and anchors for concrete and bricks.

The closed type of support, in comparison with the open one, seems to be a more reliable type of construction. The price is not much different, but in terms of reliability there are interesting points.

The fact is that the "ears" of the closed support are arranged in such a way that they look at each other. This makes it possible to press the timber during installation, which naturally leads to simplified work and, in a general sense, to an increase in the strength of the whole structure.

Note! It can also be noted that the closed support has an attractive appearance, because the place of attachment is almost not visible.

The closed support is recommended in connection of two beams of bearing type. Holes in the steel allow installation, as nails and screws.

Note! When using a closed support, and especially when working with bearing beams, the choice of fasteners, nails, screws, anchors, is made taking into account the load on the beam!

Unlike corners and plates, in this fixture additional stiffening ribs are not used. Moreover, the closed support is excellent for connecting any section of the beam, and most importantly, the angle can be not only strictly 90 degrees, but also more acute.

Sliding bearing для стропил

As soon as the construction approaches the installation of the roof, you will need an indispensable fastener, which is called the sliding support of the timber.

The particular importance of this element is due to the fact that wood in the construction process tends to change its physical dimensions, that is, to shrink. This is especially evident during the operation, which is why it is always recommended to leave wooden houses for shrinkage for several months, and only then begin finishing work.

Shrinkage leads not only to the curvature of the box at home, to small deformations of the timber, but also to the weakening of the roof connections. Do-it-yourself can prevent this process by using sliding supports for rafters.

The essence of the mount is as follows:

• Rafters are attached to the supporting element, beam, timber.
• After assembly, the entire structure becomes balanced.
• It is possible to use a sliding support to connect not only one, but also two or more rafters to a fixed base.
• For mounting there is no need for special equipment.
• The overall complexity of the installation of the roof decreases several times.
• Installation can be made, as using usual nails, and screws on a tree.

In the manufacture of this fastener used steel with a thickness of 2 -2.5 mm. The metal is galvanized, therefore, does not require additional anti-corrosion treatment.

In addition, the design of the sliding support involves the use of a closed type of product. In this case, this type is used for attaching rafters to the power plate. It also works the principle of compensating for the natural shrinkage of a wooden building.

Plates

The plate, as well as fastening corners for timber, is the simplest and most sought-after product among the variety of perforated metal for fasteners.

Moreover, for such high demand there are simple prerequisites:

• High degree of reliability. In the manufacture of galvanized steel is used, with a thickness of 2.5 mm.
• Complete ease of use.
• The widest scope of application is the connection of timber, beams, logs, rafters.

The perforated plate allows the use of nails, screws, screws, anchors, any type, depending on the weight of the structure and the task to be performed.

Elevator adjustment in height

This type of fastening consists of two steel sheets, pre-galvanized. Steel thickness 6 mm.

Fully construction consists of:

• Galvanized steel sheets.
• Studs with metric thread, labeled M24 and M16.
• Nuts of suitable size.

This type is used to exclude a change in the horizontal level during shrinkage of a log house. After the box of the house is built, it will shrink anyway. Lift allows you to compensate for shrinkage.

Conclusion

Metal fastening of timber, as can be seen from the above, fully meets all the requirements, both installation work and the safety and reliability of the structure in operation.
