Türk sarıçamından lamine ahşap krişlerin mekanik özellikleri

Mechanical properties of laminated wood beams produced from Turkish pinus silvestris

Özet

Türkiye’de yeni yeni tanınmaya başlayan, Avrupa ve Amerika’da çok uzun yıllardır yaygın olarak kullanılan lamine ahşap teknolojisinde kiriş üretiminin yapılabilirliğinin belirlenmesi esas amaçtır. Bu amaca ulaşabilmek için aşağıdaki yöntem izlenmiştir. Bu teknolojinin yaygın olarak kullanıldığı ülkelerdeki üretim incelenmiş ve kendini çabuk yenileyebilen kozalaksı çam türlerinin işlendiği görülmüştür. Bu belirlemeden sonra Türkiye’de yetişen kozalaksı çam türleri araştırılmış ve amaç doğrultusunda Sarıçam’ın ana materyal olarak kullanılmasının uygunluğuna karar verilerek, farklı tutkallarla kirişler üretilmiştir. Üretilen kirişlerin mekanik özelliklerinin değişimi deneysel olarak incelenmiştir. Sonuçlara bağlı olarak Türkiye’de üretiminin yapılıp yapılamayacağı ve uygulamaya yönelik öneriler sunulmuştur.

Abstract

In today’s world, choosing the right material without any harmful effect and with high energy efficiency is an important decision to take for maintaining balance of natural environment. Sustainability of used materials and architectural design are highly important factors for satisfying the natural balance. Considering this wood is appeared as the best material with its uniqueness and special sustainability properties. With developing technologies all around the world, small slices of glued-wood can be used for many purposes, as creating wide-broad areas with produced materials in various kinds of shapes, avoiding wastage of wood. This new usage form of wood is called as glued-layered (laminated) wood in today’s design world. In this study, the main objective is to research and analyze the possibility of beam production by laminated wood technology that had already been used in Europe and in America for many years, but is recently known in Turkey. For achieving this, findings obtained from studies of main user countries had been analyzed and this revealed that especially pine species have been chosen for this production. Afterwards pine species in Turkey have been analyzed and found out that pinus silvestris is the appropriate choice and had been successfully used with many types of glues. Performance values of produced beams had been observed experimentally. As a result, suggestions on production availability and implementation techniques in Turkey had been given.
