Abstract

Aim
of study:
The purpose of this study is to investigate the effect of
the pilot-hole, screw type, screwing direction, water retention and adhesive on
the screw pull resistance of the plywood.

Material
and Methods
: Two types of screws, 3.5 mm and 4 mm in diameter, were
used in the study. The supplied 18 mm thick plywood is sized to 50 mm x 50 mm
according to TS EN 13446 standards. The pilot-holes were drilled so that 80% of
the screw diameter would be used. After the polyvinyl acetate (PVAc) and
polyurethane (PU) adhesives were injected into the pilot-holes, screwing was
carried out perpendicularly and horizontally to the surface of the sample. Half
of the samples were immersed in water for 2 hours before the screw withdrawal
test. The results of the tests were interpreted by statistical analysis.

Main
results:
When examining the results, all of the pilot-hole drilled
samples showed higher screw withdrawal resistance than the pilot-hole drilled
samples. It was also found that the screw withdrawal resistance perpendicular
to the surface is higher than that parallel to the surface. When the glue
applied pilot-hole specimens were examined, the PU specimens showed higher screw
withdrawal strength than the PVAc specimens. A lower screw withdrawal strength
was determined when samples were immersed in water. It was also found that as
the screw diameter increases, the screw withdrawal strength increases.







Research
highlights:
In is concluded that applying PU in pilot-holes before
driving screw in significantly affected screw holding performance in plywood.

Abstract

Özet

Çalışmanın
amacı:
Kontrplağın vida çekme direnci üzerine kılavuz deliğinin,
vida tipinin, vidalama yönünün, suda bekletmenin ve yapıştırıcının etkisini
araştırmaktır.

Materyal
ve Yöntem:
Çalışmada çapları sırasıyla 3.5 mm ve 4 mm olmak
üzere 2 tip vida kullanılmıştır. Temin edilen 18 mm kalınlığındaki kontrplak TS
EN 13446 standardına göre 50 mm x 50 mm boyutlarında ebatlandırılmıştır.
Kılavuz deliğinin çapı, testlerde kullanılan vida çapının %80’i olacak şekilde
delme işlemi yapıldı. Polivinil asetat (PVAc) ve Poliüretan (PÜ) tutkalları
kılavuz deliklerine enjekte edildikten sonra örnek yüzeyine ve kenarına
vidalama işlemi gerçekleştirildi. Örneklerin yarısı 2 saat süre ile suda
bekletildikten sonra vida çekme testleri yapıldı. Testlerin sonuçları
istatistik analiz ile yorumlandı.

Sonuçlar: Sonuçlar incelendiğinde kılavuz deliği açılmayan örnekler daha
yüksek vida çekme direnci göstermiştir. Ayrıca yüzeyden uygulanan vida çekme
direncinin kenardan uygulanana göre daha yüksek olduğu tespit edilmiştir.
Tutkal uygulanan kılavuz delikli örnekler incelendiğinde Poliüretan (PÜ)
uygulananların vida çekme mukavemeti Polivinil asetat (PVAc) uygulananlara göre
daha yüksek olduğu belirlenmiştir. Suda bekletilmiş örnekler incelendiğinde
daha düşük vida çekme mukavemeti göstermiştir. Ayrıca vida çapı arttıkça vida
çekme mukavemetinin arttığı tespit edilmiştir.













Araştırma
vurguları:
Kontrplakta vidalama öncesinde kılavuz deliklerine PÜ
uygulanması vida tutma performasını önemli ölçüde etkilemektedir.
