WOOD SCREW WITHDRAWAL RESISTANCE OF SOME IMPORTANT TREE SPECIES GROWING IN EASTERN BLACKSEA REGION

Year 2001, Volume: 2 Issue: 1, 54 - 60, 18.03.2011

Abstract

This study was
carried on the screw withdrawal resistance of stem wood material of Fagus
orientalis Lipsky., Alnus
glitunosa subsp. barbata (C.A.Mey)
Yalt., Castenea sativa Mill.,
Picea orientalis (L.) Link., and Pinus
sylvestris L. The wood samples of these tree species
were collected from forest districts in Gümüshane,
Trabzon and Artvin. Tests were carried out according to the TS 6094 and ASTM-D
143 and ASTM-D 1761 on 60 samples of each one of the tree species. Half of the
samples were 12 % and the other half were 30 % moisture contents. The
dimensions of wood materials on which the tests carried out are 50 x 50 x 150
mm. Screws used for withdrawal tests were 4.5 mm in diameter and 40 mm in
length. Two screws were inserted into lead holes at right angles on the
tangential surface, 26 mm penetration. The results showed that the highest
screw withdrawal resistance was found for oriental beech among the five tree
species. The order of screw withdrawal resistance from the higher to the lower
was found as fallows; alder, chesnut, pine, spruce. In regards to moisture
effects, the screw withdrawal resistance were found higher at 12 % moisture
content.

Abstract

Bu çalışmada; Doğu Karadeniz Bölgesinden (Gümüşhane, Trabzon, Artvin)
elde edilen Doğu Kayını (Fagus orientalis Lipsky.), Sakallı Kızılağaç
(Alnus glitunosa subsp. barbata (C.A.Mey) Yalt.), Anadolu Kestanesi
(Castenea sativa Mill.), Doğu Ladini (Picea orientalis (L.) Link) ve
Sarıçam (Pinus sylvestris L.) odunlarının vida tutma dirençleri
belirlenmiştir. Denemeler TS 6094, ASTM-D 143 ve ASTM-D 1761
standartlarına uygun olarak 60’ar örnek üzerinde gerçekleştirilmiştir.
Örneklerin yarısında rutubet miktarları % 12, diğer yarısında ise % 30
olarak seçilmiştir. Örneklerin boyutları; 50*50*150 mm olarak
alınmıştır. 4.5 mm çapında ve 40 mm boyunda ağaç vidalar kullanılmıştır.
Örneklerin teğet kesitinde açılan klavuz deliklerine, iki adet vida 26
mm derinliğe kadar vidalanmıştır. Sonuç olarak; ağaç türlerine göre
en yüksek vida tutma direnci Doğu Kayınında elde edilmiş, onu sırasıyla
Sakallı Kızılağaç, Anadolu Kestanesi ve Sarıçam izlemiş, en düşük vida
tutma direnci ise Doğu Ladini odunlarında elde edilmiştir.
Rutubetin etkisine göre ise; % 12 rutubet miktarındaki örneklerin vida
tutma direnç değerleri yüksek çıkmıştır.
