Gable roof - on the device instruction

device elements and gable roof

gable roof comprises two inclined planes called ramps connected to the ridge and at an angle to each other.This angle is called the angle of inclination of the roof, it depends on the functionality of the mechanical characteristics of the roof and the choice of roofing.On the short sides of ramps form triangles.They called gable roof.

«skeleton» of the roof, its framework consists of the following elements:

1. mauerlat - support beams, laid on top of the opposite wall of the structure and transmit the load from the roof on the house wall.On mauerlat based floor joists or rafters - it depends on the type of roof.Mauerlat role in a wooden house usually plays the upper crown of a log house, a stone structure mauerlat attached to the top row of masonry using anchor bolts.The material used for mauerlat - timber from dry softwood section 100x100 mm and 150x150 mm.
2. rafters are designed to form the "triangle" of the roof - they are installed in pairs on both sides of the roof and connected to the ridge, forming a truss system.Rafter roof form the main circuit, a step of installation depends on the geometric dimensions and the type of roof covering, as well as the calculated snow and wind loads.It is usually in the range of 60-120 cm Material -. Edged board thickness not less than 50 mm, softwood.To increase the strength of the board is put on the end face.
3. Racks - mounts designed to maintain the truss system.Vertically mounted racks in the ridge of the roof with a width of 8 meters and mounted between the eaves and the ridge.They are made of timber 100h100mmili150h150 mm.
4. Runs - horizontally laid beams, designed to support the roof system.Runs lean against a rack and run parallel mauerlat.The material - a bar 100x100 mm and 150x150 mm.
5. Tightening - beams, laid horizontally perpendicular mauerlat.His appointment - bond rafters, tightening does not allow construction to disperse in different directions.The cross section of the beam is the same as that of mauerlat.
6. Lejeune - horizontal support beams located on the inside of the retaining wall.On his desk set, supporting truss system.The material - a bar 100x100 mm and 150x150 mm.
7. Struts - inclined supports, installed at a certain angle to the rafters and truss connecting the system to the farm - a rigid structure capable of withstanding heavy loads.Struts set on inhaling or sill and made of planks 50h150 mm or 100x150 mm.
8. roof battens - the system of boards or bar, and sometimes made of plywood, on which is laid roofing type selected.The design of crates and her step depends on the stiffness of the roofing.

elements gable roof

presence of certain elements in the "skeleton" of the roof depends on the type and geometry.Rafter system gable roof is of two types: naslonnaya and hanging.Rafters naslonnogo type based on the upper end of the ridge beams, or run, laid on the rack, and the lower - at mauerlat.The wooden rafters and compound structures mauerlat perform sliding to avoid the deformation of the roof with the shrinkage of the house.Hanging rafters rest on top of each other, and the bottom - on the joist or puff.To provide additional rigidity roof trusses tightening the bolt and install struts.

Options roofs with hanging rafters and naslonnymi

Installing a gable roof with rafters naslonnymi

1. On the exterior walls on the long side of the building is laid mauerlat - beam section 100x100 or 150x150 mm.Mauerlat fixed to the wall at the anchor bolts, aligning the timber on the inner side of the wall.Under the beam necessarily put a double layer of tar paper or other roll waterproofing.On the inner wall of the carrier in the same way put sill - beams of the same cross-section as mauerlat parallel to it.
2. On mauerlat sill and floor beams are laid out board 50h150 mm increments equal to the calculated step rafters -. 60 to 120 cm On temporary lay beams subfloor from any of the boards, sufficient strength to them could walk.Boards for safety of movement secured by conventional nails.
3. On sill support set of timber 100x150 mm rack in increments of 1.5-2 meters.They are aligned with the level and plumb, and temporarily fix the struts - any suitable boards.Jib put at an angle in two directions, so that the racks are properly secured.Racks secured to the sleepers with nails 150 mm and metal parts.
4. on rack placed ridge beams, or run, cross-section 100x150 mm.He secured the same way: on nails and corners.If the ridge is longer than the standard length of timber, dock it on the rack, additional bonding metal plates and brackets.

5. From the board not less than 50 mm thick, making the rafters.First, perform a pattern: the board is applied to the ridge beam at at desk and mauerlat, mark and cut out gashes.Washed down depth should not exceed 1/3 of the board width.If the length allows rafters, roof overhangs left at least 0.3 m. The resulting pattern is applied to both the roof slope at the level of the floor beams, and if you do not need the size of the adjustment, just cut out the required number of trusses.
6. Krepjat rafters above the ridge beam to each other by means of metal plates and nails, as well as the timber - each rafter on two nails.By mauerlat rafters are fixed by means of metal staples.Staples to evert clogging so that their sharp ends were turned perpendicular and pierce one edge in a rafter, others - in mauerlat.

7. If the roof width of more than 8 meters must be installed struts.They are made of edged board and set at an angle of 45 degrees to the horizontal.Buckled reinforce each rafter.The lower part of the strut rests on the sill, for this board is applied at a selected angle to the sleepers, mark and perform gash, attach strut nails.The upper edge of the brace rests on the rafter to rafter his nails fastened by means of metal plates.

8. If rafter length does not allow overhang of the roof, the rafters are fixed fillies - the board, and continue their pro-roof edge.On the front sides made curtain fillies perpendicular to the rafters.Filly made from the same boards as rafters, attach them to the nails of 100-150 mm.Trim them as needed and nailed eaves and wind braces, and then proceed to the implementation of crates.

device gable roofs with hanging rafters

1. Install mauerlat similarly naslonnymi roof rafters.As the system with hanging on mauerlat rafters are also bursting strength, it is further secured to the inside of the metal plate.

2. rafters made of boards at least 50 mm thick.First, perform a template.Apply a board at a right angle to the mauerlat and mark a line washed down.Doing this is more convenient together.

3. On overlapping establish temporary stands, and on them - the ridge board 50 mm thick.Racks time strengthen the struts, pre-aligning them.On the ridge board mark out the upper section of the template.
4. sawn Apply a template rafter at several points.If no adjustment is required sizes, we can start making this pattern rafters.Their number depends on the selected pitch.
5. Install rafters on mauerlat, emphasizing them with the washed down, and is attached with nails on the corners.To secure the ridge board rafters just nails - thanks to the palm rafters securely stand on mauerlat.
6. Install the tightening of the planks of the same section.They applied to the rafters fix nails and drilled a through hole through which a board is fixed to each other on the bolts or studs.

7. Stow stoyki.Tak time as the rafters hanging type end at mauerlat to them necessarily attach filly, forming a roof overhangs.After that you can start sewing the gables, supporting wind and curtain bars, sheathing, insulation and flooring roofing.

For smaller buildings is usually chosen from the roof trusses hanging system - it is easier to fulfillment, it has fewer elements, hence, cheaper.

reliability of such a roof is very high at the correct load calculation.Rafters naslonnogo type withstand heavy loads, so they are often used in homes with attic and insulated roof.
