SIFAT MEKANIK PADA SAMBUNGAN KAYU NYATOH (Palaquium xanthochymum Pierre) BERDASARKAN BENTUK SAMBUNGAN DAN MACAM ALAT SAMBUNG
Abstract: The wood with a long
stretch increasingly scarce, so their use limited variety. Therefore it is
necessary for splicing. Jointed wood has lower strength than wood intact,
because of shift caused among other selection shape and the lack of proper
connecting equipment in a construction. Two factors of treatment in this
research are shape the connection (connection angled lip hooked and lip
straight connection) and type of connecting tools (pegs, nails and bolts) with
three replications. Measured parameters in this study are the mechanical
properties of wood connections on the static bending persistence and
determination of bending fracture. The sample size is (W) 5 cm x (H) 5 cm x (L)
76 cm. Then testing the Modulus of Elasticity (MOE) and the Modulus of Rupture
(MOR). The results showed that the value of the MOE decreased 81.31% - 90.45%
and MOR 81.71%- 91.55% value also
decreased when compared with the control and the value entered in the category
of strong wood class V. The low value of the MOE and MOR is found in the
connecting tool like pegs and bolts. Thus resulting in the dissolution of the
wood fibers and consequently the strength of the connections is low. Then the
tool also decreases the strength of nails connecting wood used due to the small
diameter of nail (2.8 mm) and use only two sticks nails in one connection.
Results of this research on the wood connection with the treatment Nyatoh wood
(Palaquium xanthochymum Pierre) used for construction purposes only under the
roof only, for example gording, murplat, and plafond which is supported by the
use of pillar.
