Hip And Valley Roof Framing Plan

Part of a framing plan for a hip roof is shown infigure 18 3.

Hip and valley roof framing plan.

Parts of a roof the main structural parts of a roof are ceiling joists ridge board jack rafter hip rafter common rafters creeper rafters raking plates out riggers and noggings or last rafter overhang. A corner fireplace offers warmth throughout the shared spaces. Intersecting the intersecting roof consists of a gable and valley or hip and valley. Now draw the centerlines for all rectangles that are formed inside.

Divide the rise by the run the run is 12. Place the 4 6 common rafters in their designated positions along the 2 longest walls and nail them firmly to the wall with a nail gun. This type of roof is also called broken back hip and valley roof because the main hips are intconeected by the rafter of gables on one side and the rafter of the valley on the other. These hip rafters run at a 45 angle from each corner of the building to the ridge.

The valley is formed where the two different sections of the roof meet generally. Tie down fixings tie down fixings are used to resist uplift and shear forces lateral loads in floor framing wall framing and roof framing. Label and identify the parts of a roof framing plan. Such buildings may have more than four hips in the roofs and they form valleys at the inside corners.

Define ridge board rafter hip valley sheathing fascia soffit dormer and pitch. The hip and valley factor varies according to the slope of the roof as shown in the table below. For any roof slope expressed as x in 12 rise in run the hip and valley factor is determined by finding the square root of rise run 2. Now outline the biggest rectangle inside the building layout.

First of all you need to design the layout of building. The point at which all the rafters are attached to. The first step in the process of erecting the hip roof is to get the ridge beam into place at the top of the roof. Porch roof extensions for hip roof porch extensions from an existing building wall you can use half the calculator results.

Stone and horizontal siding hug the exterior of this 3 bedroom ranch house plan topped by a hip and valley roof a hallway off the formal entry leads to two family bedrooms separated by a full bath which they share the heart of the home is rear facing and open creating a cozy space for easy interactions with family and friends. Transfers the load of the roof. A hip and valley roof may be part of an irregular structure. Attach 4 6 centering rafters and lift the ridge beam into place.

Remember that a line on the framing plan indicating a rafter represents the total run of the rafter but not its actual length. On a hip roof framing plan the lines that indicate the hip rafters ec ac kg and ig in figure 18 3 form 45 angles with the edges of the building. Here roofs are constructed with an angle of 90 degrees. Hip and valley roof framing is no so complex as compared to hip roof framing procedures.

Minus ridge thickness to allow for ridge becoming pole plate roof peak will be slightly higher ridge thick must be same.
