Özet:

 Background and aims OSBs are an engineered wood-based composite material and is widely used especially in the construction and furniture sectors. Screw connections are one of the critical elements that determine the mechanical strength of OSB. The aim of this study is to investigate the effects of pilot hole diameter, pilot hole depth and board thickness on the screw direct withdrawal resistance in OSB. In the study, screw direct withdrawal resistance was tested by using 11mm and 18mm thick OSBs, taking into account different pilot hole diameters 60 and 85, pilot hole depths 50 and 80 and screwing directions edge and face. Methods Uncoated 11mm and 18mm thick OSBs were used in the experiments. Zinc-plated sheet steel screws 3.530mm were used. Results The results showed that pilot hole diameter, depth, and screwing direction significantly affected screw withdrawal resistance. A 60 pilot hole diameter and 50 depth provided higher resistance than 85 and 80, respectively. Face screwing yielded greater strength than edge screwing. While OSB thickness had no significant effect, 18 mm boards showed slightly higher resistance on average. Conclusions The factors should be selected correctly in order to use OSBs more safely and efficiently in engineering and construction applications. In particular, it is recommended to prefer face screwing and to use a pilot hole diameter of 60 and a depth of 50 in proportion to the screw diameter. These findings will contribute to the creation of more reliable and durable connections in the areas where OSBs are used.

 Giriş ve Hedefler OSBler levhalar, mühendislik ürünü ahşap esaslı kompozit malzemeler olup, özellikle yapı ve mobilya sektörlerinde yaygın olarak kullanılmaktadır. Vida bağlantıları, OSB levhaların mekanik dayanımını belirleyen kritik unsurlardan biridir. Bu çalışmanın amacı, OSB levhalarda pilot delik çapı, pilot delik derinliği ve levha kalınlığının vida çekme direnci üzerindeki etkilerini incelemektir. Çalışmada, 11mm ve 18mm kalınlığındaki OSB levhalar kullanılarak farklı pilot delik çapları 60 ve 85, pilot delik derinlikleri 50 ve 80 ve vidalama yönleri kenar ve yüzey dikkate alınarak vida çekme dirençleri test edilmiştir. Yöntemler Deneylerde yüzeyi kaplanmamış 11mm ve 18mm kalınlığındaki OSB levhalar kullanılmıştır. Çalışmada 3,530 mm boyutlarında sunta vidalar kullanılmıştır. Bulgular Elde edilen sonuçlara göre, vida çekme direnci üzerinde pilot delik çapı, derinliği ve vidalama yönünün önemli bir etkisi olduğu tespit edilmiştir. Pilot delik çapının vida çapına oranı 60 olduğunda, 85 oranına kıyasla daha yüksek vida çekme direnci sağlanmıştır. Benzer şekilde, 50 pilot delik derinliği, 80 derinliğe göre daha yüksek mukavemet göstermiştir. Vida bağlantılarında yüzey vidalamanın kenar vidalamaya kıyasla daha yüksek çekme direnci sağladığı belirlenmiştir. OSB levha kalınlığının ise vida çekme direnci üzerinde anlamlı bir etkisi olmadığı, ancak 18 mm kalınlığındaki levhaların ortalama olarak daha yüksek çekme direncine sahip olduğu görülmüştür. Sonuçlar OSB levhaların mühendislik ve yapı uygulamalarında daha güvenli ve verimli kullanılabilmesi için pilot delik çapı ve derinliği gibi faktörlerin doğru seçilmesi gerektiğini göstermektedir. Özellikle, yüzey vidalamanın tercih edilmesi ve vida çapına oranla 60 pilot delik çapı ile 50 derinliğin kullanılması önerilmektedir. Bu bulgular, OSB levhaların kullanım alanlarında daha güvenilir ve dayanıklı bağlantılar oluşturulmasına katkı sağlayacaktır.
