Jan 23,2012 ground supported tanks top angle attachment for self supporting roofs#0183;API-650 includes a section for calculating thickness of self-supporting roofs; you work through it backwards to find the minimum slope.Note that API-12D,12F,and UL-142 all have different slope requirements from API-650.Rooftop Support Systems Green Link KnuckleHeadStrut Support.Strut KnuckleHeads are engineered to accommodate steel or aluminum channel which can be configured to support all types of HVAC equipment such as air conditioning units and multiple conduit lines,or for installing solar arrays at proper angles.Height extensions up to 18 are available.Roof Structures - UnitCareIn traditionally constructed roofs,the roof may also require added support in the form of roof trusses.This will depend upon the size of the roof and the type of roof covering the roof has to support.In modern double roof construction,the whole of the roof is constructed of lightweight roof trusses called trussed rafters (See Module 4).
Roof Framing collar ties,rafter ties,tension beams structural ridge beams some of these can support the roof and prevent ridge sagging and wall spreading.This article describes and illustrates the different types of support that prevents roof sagging and wall bulging at buildings,including definitions of collar ties,rafter ties,and structural ridge beams.ROOF FRAMING - Construction Knowledge.netThe hip roof has four sloping sides.It is the strongest type of roof because it is braced by four hip rafters.These hip rafters run at a 45 ground supported tanks top angle attachment for self supporting roofs#176; angle from each corner of the building to the ridge.A disadvantage of the hip roof is that it is more difficult to construct than a gable roof.Intersecting The intersecting roof consists of a gable ROHN G-Series Self Supporting Tower -Low Cost SolutionROHN Self-supporting G-Series towers offer an easy,low-cost solution to get light weight self supporting antenna towers in the air quickly.By using the G-Series tower as a self-supporting tower,you minimize land area usage..ROHN tower manufacturing Self-Supporting G-Series towers are functional in a wide variety of wind speeds,with and without ice.
