(Above) An improved jointing system for bamboo has recently been developed by DOST-FPRDI using common construction materials – cement, sand, steel plates, nuts and bolts, and rebars.
According to the Institute’s Engr. Christian S. Camacho, “This method is superior to traditional jointing methods such as lashing since the mix of steel and concrete keeps the bamboo poles from slipping from each other. The system likewise preserves the strength of bamboo as no holes or cuts are made to fit the various parts together, unlike in other jointing methods.”
Added Camacho, “Using the improved method, we made a space frame from bolo bamboo (Gigantochloa levis) to test the joint’s strength and found that it can easily hold up to 1,000 kilos.”
“Using the jointing system, different geometrical shapes can be made. The space frame can be developed some more and used for different applications such as temporary tent, car port , waiting shed or emergency shelter,” he said.
The FPRDI bamboo jointing system is a simplified version of similar systems already in use in other countries. (Rizalina K. Araral, 23 September 2015)#
