Mühendislik Ürünü Ağaç Malzemelerde Yükselen Trend; Çapraz Tabakalanmış Kereste

Abstract

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

Abstract

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.
