Hipped roof with his hands : for building Instructions

Roof

Trehskatnaya roof - an original architectural solution, suitable for all devices of the roof structure, as well as for individual elements of a complex roof.It is a hybrid of a conventional gable and gambrel roof and consists of three rays: two of them - in the form of trapezoids, connecting in the ridge, and the third - an equilateral triangle, otherwise referred to as hip ramp.

Trehskatnaya roof with his hands

device trehskatnoy roof gable slightly more complicated, unlike it is to install two Plait adornments rafters forming the hip ramp, as well as designs, podderzhivyuschih the rafters.Plait adornments rafters are usually much longer than the side, so their performance is necessary to choose the board greater thickness and length or splice existing standard timber.

trehskatnoy roof elements and their purpose

trehskatnoy roof frame is formed by the following elements:

mauerlat - beams, laid around the perimeter of the outer walls and redistribute the load of the roof to the walls;

Lejeune - interim board, stowed on the internal load-bearing walls;
Floor beams - planks laid on mauerlat employees and frame overlap between the floor and the attic or loft;
stands vertically supporting beams holding the roof frame;
ridge beam - laid on the vertical rack rail, employee support for the truss system;
Rafters - boards stacked with a certain step, and based on the ridge beam and the rack at the top and at the bottom of the mauerlat.Rafters trehskatnoy roof divided into lateral and Plait adornments;
Sprengel - vertical support, supporting rafters Plait adornments;
Struts - board mounted at an angle of about 45 degrees to the horizontal struts and employees between the rafters and floor beams or sleepers.

Connection elements is carried out using metal angles and gains, fixed with nails, screws or studs with nuts.

trehskatnoy frame roof and its structure

materials trehskatnoy roof

Traditionally, performance truss system and crates used softwood lumber, dried under a canopy with a residual moisture content of no more than 15-20%.When choosing a timber you need to check for the absence of traces of rot and mold, darkening wood.Timber truss system for the device is coated with an antiseptic, and to improve the fire resistance and fire retardant composition.

mauerlat, sleepers and racks are usually made of timber section 100x100 or 150x150 mm.Joists and rafters - on board of 50 mm and a width of 200 mm, with their narrow side is laid down to reduce sagging elements.Plait adornments rafters bear a significant burden, their recommended from a bar of rectangular cross section 100x150 mm.You can also Plait adornments rafters of two spliced boards: between stack trim boards and styagivyut them at this point on the studs.

important element is the roof battens - boards of 20 mm thick, stacked to the rafters with a certain step in parallel ridge beam.To perform roofing lath MIGA solid - made of plywood.In addition to lumber, to carry out the roof using roofing, hydro - and wind-proof film insulation and vapor barrier.

technology implementation trehskatnoy roof

first step in the device trehskatnoy roof with his hands - laying mauerlat.The selected timber mark out the length of the walls and joints in the corners of her strictly at an angle of 90 degrees, shifting it to the inside of the walls.The brick wall mauerlat fastened with anchors, pre-roll after putting n wall waterproofing material in two layers.Bruce mauerlat need to carefully handle disinfectant.On the inner walls of stacked sleepers, as laid between the wall and the wood waterproofing coating.

way mauerlat
Over mauerlat or in specially designed for this purpose grooves in the walls put floor beams from boards 50x200 mm or thicker.The board is placed on the end - it increases its bending stiffness.The beams are placed in strict order: first the extreme, then stretched lace on intermediates.Step between the beams can be anything in the range of 50 to 120 cm, but if you plan to insulate the ceiling with modern materials, it is recommended to keep a distance between them of 60 cm width equal to the insulation.The height of the beams overlap is controlled by a wooden linings.For convenience, you can lay on top floors draft floor loft of any solid boards - installation of the roof at the same time greatly facilitated, the safety of the work will increase.
vertical racks, depending on the floor structure and the presence of internal partitions, or put on the floor beams, or on the sleepers, passing precisely in the middle of the roof.Beams made of a timber of square or rectangular cross-section.They are put in place and align the plumb, and then fastened in a vertical position with the help of temporary struts and struts.By the sleepers or joists rack fastened using metal or wooden linings.The number of racks on the roof trehskatnoy must be such that the distance between them does not exceed 2 meters.In any case, the counter is set at the edge of the roof, forming a vertical gable and at the junction with the ridge rafters Plait adornments.
on rack placed ridge beam and fasten it with the corners and linings, after checking the distance to both the eaves and corners to hip slope.The roof must be absolutely symmetrical.
Side roof rafters trehskatnoy are naslonnye rafters, the upper end fixed to the ridge batten and the bottom - at mauerlat and joists.They operate on a template: the board is applied at the site of attachment at the feet of truss, mark her gash, serving for support on the ridge beam.With this pattern, cut the required number of rafters and fastened them first to the ridge beam in the corners, and then, at the place of marking up on each rafter bottom gash, and mauerltu.Rafters put on mauerlat next to the joists so that they could pull the pin on - it will increase the rigidity of the truss.Step rafters with equal step joists.
side rafters reinforce the braces of the boards mounted on joists at an angle of 45 degrees to the horizontal.The thickness of the braces is usually equal to the thickness of beams and trusses - 50 mm.In this case the upper part stays attached to the rafters by means of pins.

Strengthening lateral rafter braces made of logs
Plait adornments rafters mark out the place: opirajut designed for this board or timber in the rack and mark out the upper oblique gash, cut out, after which it is applied to mauerlat at the point of the corner joints andmark out the place of the lower gash.Fix Plait adornments rafters using corners and linings and further strengthen narozhnikami - props forming a ramp hip and resting on the lower end of mauerlat and top - Plait adornments at the rafters.

Installation Plait adornments rafters for the roof trehskatnoy
At great length Plait adornments rafters further strengthen their racks mounted underneath and attached to the joists - Sprengel.

Strengthens Plait adornments rafter beams
After installing the truss system and remove temporary gantries are to commence crates.Material for lathing as its step depends on the roofing.Under the decking and metal roofing requires sparse crate from the boards of 25 mm, Ondulin and soft roof - solid plywood.

Mounting battens on the roof trehskatnuyu
Trehskatnaya roof can become an ornament, not only at home but also pavilions, baths or other buildings.When orienteering hip slope toward the prevailing wind load of the roof's ability to withstand strong winds increased significantly.
