Binaların, insan ve çevre sağlığı üzerinde önemli bir etkisi vardır.
Bina üretiminde kullanılan kaynakların sürdürülebilir olması, az atık çıkarmaları,
daha az sera gazı salgılamaları, üretimlerinde daha az su ve enerji
kullanılması, insan sağlığı ve çevre üzerindeki etkilerinin az olması günümüzde
öne çıkan en önemli unsurlardır. Çapraz tabakalanmış kereste (ÇTK), çelik,
beton ve duvar gibi geleneksel yapı malzemelerine sürdürülebilir “yeşil” bir
alternatif olarak ortaya çıkmıştır. ÇTK, dikdörtgen veya kavisli biçimde
paneller oluşturmak için farklı yönlerde istiflenmiş, tutkal ve basınç ile
yapıştırılmış bir mühendislik ürünü ağaç malzemedir. Bu paneller bina
inşaatlarında zemin, duvar ve çatı olarak kullanılmaktadır. Yüksek mukavemet,
boyutsal sabitlik ve tasarım esnekliği ile ÇTK, birçok bina tipinde, beton,
duvar ve çelik gibi geleneksel yapı malzemelerine karşı oldukça avantajlı bir
alternatif olduğunu birçok uygulamada kanıtlamıştır. ÇTK panelleri tek sayıda
kereste katmanından (genellikle üç, beş, yedi veya dokuz) oluşur. Bu paneller,
her proje için ve her kesim için özel olarak tasarlanmıştır. ÇTK panelleri
yerinde önceden üretilip monte edildiğinden, inşaat süresi azaltmakta ve
üretimlerinde neredeyse hiç atık oluşmamaktadır. Bu çalışmada bu ürünlerin
üretim süreçleri, özellikleri kullanımı, avantaj ve dezavantajları ile dünya
pazarındaki yeri hakkında bilgi verilmeğe çalışılmıştır.

Rising Trend in Engineered Wood Products; Cross Laminated Timber

Öz

Buildings have a significant impact on human and
environmental health. Today, the most important factors in building sector,
less waste extraction, less greenhouse gas emissions, less water and energy consumption
in their production, low impact on human health and the environment are factors
that stand out. Cross laminated timber (CLT) has emerged as a sustainable
“green” alternative to traditional building materials such as steel, concrete
and wall. CLT is an engineered wood product, which is glued with glue and
pressure, stacked in different directions to form panels in rectangular or
curved form. CLT is an engineered wood product, which is combined with glue and
pressure, stacked in different directions to form panels in rectangular or
curved form. With its high strength, dimensional stability and design
flexibility, the CLT has proven in many applications that it is a very
advantageous alternative to traditional building materials such as concrete,
walls and steel in many building types. CLT panels consist of an odd number of
lumber layers (usually three, five, seven or nine). These panels are designed
specifically for each project and for each segment. Since the CLT panels are
already manufactured and assembled in place, they reduce construction time and
produce almost no waste in their production. In this study, it is aimed to give
information about production processes, properties, advantages and
disadvantages, world market of these products.
