a few tips Designing Truss Roof Garage
Roof trusses are the most important part of the design for the garage. They provide support for the roof and add strength to the overall structure. Garage roof trusses can be built on site or ordered from the manufacturer of the roof truss. Truss design will depend on the type of roof you want. Garage is most often constructed with the design of the gable, gambrel or buried.
Gable roll consists of three main members plus braces or gussets. The members of the upper or ceiling which join at an angle in the ridge line. Members under the wires down or cut at an angle at each end to fit the rafter. Total of two angles in the gable should be 90 degrees. Angle triangle either have braces or triangular gussets to increase the strength of the truss. The angle at the ridge line and length determine the slope of the roof rafters.
Garage Gambrel roof trusses, gambrel roof has a center line and ridge line of the two sides of the ridge. A gambrel truss consists of four members, two top and two side rafter rafter. The easiest way to design a gambrel roof truss design drawing is to scale the building with a straight line across the width from edge to edge overhang overhang. Using the center line, draw a half circle with a compass. Draw a line to the roof and measure angles with a protractor. Keep in mind that the triangular gussets are used to clamp the joint.
Pent roof sloping from front to back with no ridge. Rolls pent roof garage has three members and is always formed from the triangle (90 degrees) right angles. Determine the altitude of the short front roof slope. Two other members are sloping rafters and cable. As with the other truss design, truss pent-up need braces or gussets for added strength in the joints. Pent roofs are not practical in areas with heavy snowfall as the slopes are not enough to allow snow to slide off.
