Installation of roof system for the gable roof

gable roof - one of the most popular in the individual building.To build it is quite simple, the material goes away a little, and protection from rain, snow and wind, it provides a good.Construction of the roof can be seen as a separate phase, consisting of its design, the calculation of the required materials, installation of roof system, insulation, waterproofing and laying of roofing material.

Rafter system - the skeleton of the roof, and only when it is correctly calculating and fixing possible long service across the roof, without distortions, leaks and collapses.The installation of the rafters it is best to entrust the team of professionals, but if this is not possible, it is real to saddle their own, but without the helpers, in any case, can not do.

Material for rafters

to most accurately calculate the necessary amount of material is to draw (on their own or in a special program) plan truss system and its layout.Given the length of the planks and beams, you can assemble the elements that will be the minimum amount of waste.

For the manufacture of roof beams used wood of the highest category - without knots and cracks.Standard dimensions of material 50 * 150 mm at lengths of up to 6 m, and if the beam must be more than 6 m, the required board width of 180 mm in order to avoid sagging.

Attention should be paid not only to the quality of wood, and fasteners.Screws for fixing construction must be trusted by the manufacturer, with spacers between 2 mm and more.You also need to take into account the need for antiseptic treatment of wood and fire.

When erecting trusses need tools:

  1. instrumentation - precise and long tape measure (preferably 6 m or more), the level of cord for plumb, pencil marks,
  2. hammers and nails, nail puller,
  3. carpenterknife, hacksaw, saw (or chainsaw),
  4. drill, screwdriver and screws,
  5. ax,
  6. Bulgarian,
  7. templates for fastening elements of truss construction at the correct angle,
  8. emphasis to install rafter - beams 6 * 6 cmand attached on both sides of the area 40 * 40 mm,
  9. trusses for lifting cables.




Types of roof structures and elements

Rafter system for large and small roofs will be slightly different in structure, and its structure depends on the presence of the reference beam and its location, angle stingrays.

Key elements of roof system:

  • mauerlat - supporting beam thickness of 150 * 150 mm, for a more uniform load distribution on the wall,
  • rafter foot,
  • podstropilnaya leg, or bolt,
  • desk,
  • run - board50 * 200 mm, which are attached to the rafters at the top,
  • sill.

Rafters may be hanging and naslonnymi.Hanging ends attached to the walls of the house and the roof ridge, with their great length to compensate for the load on the bending and compression ties connecting the rafters.Naslonnye rafters can build the houses, inside which there is load-bearing walls, and you can use the support beam, which is attached rack.The ends of the rafters are based on the rack and on the outer wall of the house, the middle part is supported by pillars.Optimally, if the design is and the hanging, and naslonnye rafters, it makes the roof more durable.

Installation rafters

Step 1 - Set mauerlat

first step on the exterior walls mauerlat fastened with anchor bolts.It is desirable that it be integral with a minimum or compounds, this will increase the structural strength.Mauerlat must be positioned absolutely exactly as it affects the accuracy of the installation of the entire roof.If necessary, it can be inserted under the gasket, the projecting portions in abate.In the future, will be attached to the mauerlat rafters.

Step 2 - Run

Using design trusses to Run improves the reliability and simplifies the assembly of the roof, as you can mount each pair of trusses separately.Run installed at the highest point of the front wall and is secured with metal corners and anchor bolts.Its ends must be waterproofed.

Step 3 - assembly of roof sections

Before assembling rafters cut blanks, trying to use the material so that waste is minimized.If necessary, the board can be extended, focusing on the reliability of the connection, for example by using patches or overlapping.It should be located not less than a meter away from any of the edges.The compound is better not to have exactly in the middle, as the bearing capacity of the legs is reduced, the optimal location - a third of the total length.

Rafters collected according to the drawings, templates (the angles at which the elements must be positioned to each other) greatly simplify the job.The easiest way to carry out the assembly of roof section on the ground, then picking them up.However, this may require a winch or more assistants.

Initially, all elements are arranged relative to each other as they will be located in the final section.Carefully adjusted angles and gaps.Then nails are attached to the upper part of the lining the rafters, the middle leg ties are connected.In each Gvozdeva compound should be at least 5 hammered nail.By the bottom of the feet are bolted time bar.

Stage 4 - installation of roof system

Rafters raised gradually.First, at 30 degrees, then use the insurance and cables to 60. At this point in the opposite direction with the help of fixed ropes construction nailed beams and ties.Then the section is raised to the vertical position, which is checked by a level and structure is fixed with bolts and corners to run and to mauerlat.

Expose the rafters in two ways:

When you first set the first and last section, between them stretched cord, and all other parts are mounted on it.

The second - roof section mounted above one half of the house, and the other half hanging on the design and run them leans.Further, the first section is mounted on the opposite side, and the rest gradually, the process resembles a closing curtain and ends in the middle of the roof.

After mounting the roof system can start making crates, vapor barrier and insulation.
