Roof ridge and merging of the rafters: the methods and hardware

Roof - the crown of any building. Errors in its construction are fraught with serious consequences for the whole erected your home. One of the important elements of the rooftop "crown" is a horse, where the merging of the rafters. About him we are today, and it will lead.

Roof ridge: what it is and what it is for

The ridge is a horizontal member having a roof and at any connecting her skates. This element should be located at a certain distance from the run specified by the selected slope of the roof. Run also represents an additional beam are arranged parallel to both the ridge and mauerlat. In other words, the run - is raised in height mauerlat.

The main task of the entire set of connecting elements, combining in a ridge, - provide strong rigidity of the roof construction and its durability.

Splicing rafters: What methods are used to skate

In total, these methods, there are only three:

overlap

The distinguishing feature of this method is a compound trusses their lateral planes, followed by a contraction using pins or bolts. This technology is the most popular at construction of roofs.

In a wooden house can be a pillar of the upper beam, in the same block in the blocks have put mauerlat.

The most popular technique is the association of the rafters of their merging in a half-tree:

Often the rafters when Lap fastened with nails.

butt

This will require:

• rafter edge cut at an angle so that the angle was equal to the slope of the roof;
• form abutment rafters;
• use fasteners.

Apply a template can make the task easier and provide a snug fit fabrics.

For mutual bond rafters can be used nails that best complement the lining of wood or metal plate installed in the skate.

The junction may be partial:

Adjusting the rafters in such a construction is made with such precision that the load is evenly therebetween. The connection should be used as nails and tips. For this nail 30mm board with two assembly sides.

at the bar

Rafters in this case are mounted directly on a bar ridge. The advantage of the method is the ability to provide backup for the central bar, while the rafters can be strengthened in turn, when there will be a convenient moment. This method is useful when there is no time for manufacturing the template.

Compound by a ridge beam is recommended if the roof width exceeds 4.5 m. The high reliability of the design by installing additional supports that (note!) Significantly reduces the functionality of the attic.

Another variant:

This merging of the rafters is combined, because it uses a method of butt.

Fastening elements for splicing

Forming the roof contour rafters pass design load on mauerlat, which distributes it on bearing walls.

Fastening the rafters long it has been ensured by means of:

• pins made of wood;
• bars;
• linings;
• metal staples;
• pegs;
• wedges.

Now the hardware is complemented by other elements that ensure reliability and ease of working with them. Modern builders are:

• screws and bolts;
• screws;
• perforated and Gvozdeva plates and other products.

Selection of an appropriate fastener determined by the load which falls on the fastening ridge with their help node and tasks assigned to the fasteners.

Using screws rafters spliced ​​follows:

Splicing Gvozdeva and perforated plates:

The use of such plates requires press:

So, in this article we talked about the methods of matching roof beams in the ridge. the following article We intend to devote their splicing method as a part of the roofs of various configurations.
