Hipped roof with his hands - everything from measuring to installation

Construction hipped roof - what we're dealing with?

Among the types of roofs are considered to be the most durable roofs with the slope on the four sides, moreover, are characterized by a high hipped roof appeal and allow the installation of complex shapes.Depending on the structure of the plan, they can be of two types.

The square structure of four ramp form inclined sides of the same triangular shape.This option is called hipped hipped roof.If the house has the shape of a rectangle, the two end are triangular ramp and ramps on long walls take the form of trapezoids.

Since rays triangles at the ends are called hips, and the whole look is called hipped gambrel roof.At the intersections of the sides of the roof line sloping ramps are formed.Convex joints called edges.Hipped roof may have more complex structures with protruding attic windows, etc.Such joints may have a hollow angle, called the valley gutter or valley.

parameter calculation hipped roof - careful work with numbers

As the basis for all roof lie truss structure - inclined supporting beams, which are then laid flooring (crate) and a cover (roof), the construction of the hipped roof begins withvery accurate calculation on paper.Special care is required in determining the properties of angles of truss construction.

theoretical calculation hipped roof begins to make the angle of inclination, depending on the climatic characteristics of the zone.Terms recommended if the area characterized by periods of heavy rainfall, the slope increase.In general, the angle can be from ten to sixty degrees (respectively increases total material consumption).

After determining the bias, you need to mathematically derive the height of the ridge.For this are special tables with relative sizes, depending on the roof pitch.Determination of the height is to multiply the relative value to the value of half the span width of the house.

For example, for a 30 ° angle relative size of the table is equal to 0.59.Then, with a width of 10 meters of the house, the ridge height is the product of 5 to the specified rate, which is equal to 2.95 m at 25 ° slope coefficient -. 0.47, and the height of the ridge of the same width is 2.35 m

.It is important to ensure squareness skate ramps and rails.It automatically provides the correct angular skates.This calculation hipped roof parameters is easier, provided preliminary marking trusses joints places on the walls.

to properly position is determined by the length of the ridge first roughly, then checked and adjusted in the case of non-compliance.This approximate value is subtracted from the length of the wall parallel to the house.The residue was divided in half, the resulting size is checked from the edges of the end walls.If you get the right number, the payment is recorded.Similarly, the correspondence of size at the end walls, and the middle ridge beam is taken and determined to mark the center of each wall.

Now, having lengths, heights and widths of all the elements of the roof structure can be calculated geometrically.Knowing the general principle of how to calculate the hipped roof, it should be borne in mind that these rules will have a particularly small parameter calculation for different types of "chetyrehskata".So, for the hip roof rafter lengths on all slopes will be defined by the length of the edges and faces.

for hip kind of a definition line length would be on the hips and the side sections of the extreme rays from the rafters.Calculating the number of required roofing material includes a summation of the roof area of ​​the face: four triangles for the tent type and two triangular rays and two trapezoidal for the hip.

hipped roof with his own hands - we build properly

the beginning, before the build hipped roof, will be laying a log or bruschatoy mauerlatnoy design (if the rafters are made of wood).When using metal trusses, mauerlat is made of metal profile material.It is important to ensure a high quality waterproofing (several layers of roofing material) between the wall and the foundation.Secure mounting to walls mauerlat performed using appropriate anchors.

At calculations and determine how to make a hip roof, should be chosen design trusses, their shape and size, the build order and installation step, the method and materials for roofing, insulation under the roof, etc.Then to work suddenly been interrupted due to the lack of some elements.

Installation hipped fitment shek conducted the installation of roof trusses and rafters on the earlier estimates and marks.The assembly of farms is best done on a template.The use of different attendants, crossbars and braces greatly increases the rigidity of each truss, rafter, and the entire structure as a whole.

hipped roof construction must include the implementation of crates needed for the deck roofing.How to do it is determined by the type of roofing: from boards, poles or sticks, etc.lathing design depends on the roofing material.

qualitative, though more expensive, is of the crate stacked parallel to the ridge, with a pitch half a meter, bars or boards, which butt plank wooden flooring from the ridge to the eaves.For soft roofing materials is one or two layers of boards (grooved better).lathing materials should be subjected to antiseptic treatment.
