BULDING MATERIALS BAMBOO Presentation by
Bamboo is a type of grass (it is not a kind of wood) . It grows much faster . INTRODUCTION
TYPES OF BAMBOOS Monopodial This kind of bamboos are thin and long Sympodial This kind of bamboos are Short and thick Climbing This kind of bamboos are Irregular
PROPERTIES renewable versatile resource , high strength low weight , easily worked using simple tools.
LOCATION It is mainly found in tropical and sub-tropical regions .
CONSTRUCTION OF ROOFS using BAMBOOS

The roof of a building is most important component - this is what defines a construction as a shelter . roof ? ?
A roof must be , strong enough to resist the considerable forces generated by wind and roof coverings . In this respect bamboo is ideal as a roofing material - it is strong, resilient and light-weight.
Structure The bamboo structure of a roof can comprise “cut’ components - purlins, rafters and laths or battens, or triangulated (trussed) assemblies. Bamboo, in a variety of forms, is also used as a roof covering and for ceilings.
Layering of the trussers The under structure consisting of a woven bamboo net. Over that net is the first layer of interlocking split bamboo stems/shingles. Then comes a second layer of structural bamboo on the outer roof is fixed. Split Bamboo is installed on that outer roof Next is special thick and viscous rubber installation. Finally split bamboo is overlaid. This is further treated with rubber oil to protect and insulate the bamboo from the rain.
Traditional roof construction: The simplest form of roof comprises a bamboo ridge purlin and eaves beams, supported on the perimeter posts. Halved culms are then laid convex side down, edge to edge, spanning from the ridge to the eaves. A second layer, convex side up, is then laid to cover the joints. The maximum overall span using this method is about 3 Metres.
A variation on this is the use of whole culms, suitably spaced to accept battens for tiles or thatch (see Roof covering). To extend the span, a central post can be used. Beyond this, the options are almost infinite. Efficient jointing of components is a key consideration.
Trusses: Trusses offer a number of advantages over traditional forms of construction, including more economic and efficient use of materials, the ability to span larger distances, the use of shorter components (counteracting effects of bow, crook and taper) and the use of prefabrication.
Advantages of roofs using bamboos If you are looking for a green solution for your home roofing, you can use a bamboo roof. Bamboo grows abundantly in nature . It is a renewable resource that can be used for several crafts, furniture and even a home construction project. You can use a bamboo roof on your home or outdoor recreational facility. A bamboo roof is not only environmentally friendly, but is also cheap and very appealing to view.
