List of auxiliary tools for roofing of rafters
It is recommended to use tools:
- Electrical device for screwing self-tapping screws( drill, screwdriver);
- Level for measuring the smoothness of the surface;
- Saw, hacksaw for cutting the constituent parts of the crate;
- Roulette;
- Hammer;
- Pencil for marks;
- Punch, represented by a coloring rope.
Detailed consideration of the construction process for the
crate Consider, as an example of a roofing material, slate.
General outline of the structure of the roofing foundation is represented by the points:
- Purchase of the required materials for the construction of the crate
- Construction of the
- roofing system Attaching the crate
- Finishing processes before the slate decking
- Strengthening the slate sheets
We will describe the details of the stages listed below.
The choice of slate is argued by its popularity, low cost, wide use for single and double-sloped roofs. In general, corrugated or wave slate is used. It is available with standard parameters:
- 6-wave material has a thickness of 7 millimeters and a width of 125 centimeters;
- 7-wave and 8-wave - 6 millimeters thick and 130 centimeters wide;
- The length of the listed sheets is standard - 175 centimeters.
The main difference between the types of slate lies in the height and spacing of the waves( pitch).
Sheets are laid on a specially prepared base consisting of a crate and rafters. It is constructed from different types of wood. The rafters are mainly equipped with a beam of wood with a cross section of 4 by 15 centimeters, a crate - 3.5-4.5 centimeters.
All wooden materials are carefully selected before use. Their sides are sharpened, they are given an impeccably even surface. Initially, for the construction of the rafter installation, all building materials are stored in a stack, promoting the appearance of the same humidity. Drying is carried out by a natural method, after which the rafters receive a regular bend( the outer bend is called the hump, the inner bend is a chute).
Step of the roofing system for the
battens The pitch of the rafters must match the parameters of 1-2 meters. This interval is taken with calculating the length of the ridge part. The rafter structure is created from two boards according to a special scheme: they are connected under the chosen angle, its degree is determined by the type of the roof, and fixed by the bolt. For the full convenience of fastening the rafter from the edging bar, a template model is created, serving as an example for forming the correct angle of inclination.
Slate has asbestos cement components. For it, a crate must be created with a minimum cross-section of the bar, capable of bearing the required load. The lowest parameters of the bar are 3.5 centimeters. This bar is best not to use. Too much cross-section is also undesirable, it will lead to pressure on the system and can be deformed from the influence of moisture.
Fig. 7 It is necessary to correctly calculate the step of the crate
The cladding should not have frequent steps. Slate sheet is able to withstand its weight and not sag. The standard sheet size is 175 by 125 centimeters. An acceptable step for him can be 70 centimeters. Placement can be on three support parts.
