Abstract

Lamine kaplama kereste (LVL) inşaat yapılarında
kiriş, döşeme kirişi, başlıklar ve paneller gibi çerçeve üyeleri olarak etkili
ve kullanışlı olduğunu ispatlamıştır. LVL’nin türkiyede uygulaması ve üretimi
sınırlıdır. Bu çalışmada biçilmiş kayın ve kavak kaplamaları, melamin
formaldehit (MF) tutkalı kullanılarak dört farklı tipte yedi tabakalı LVL’ler
üretilmiştir. LVL’ler her dış tabaka için iki adet kaplama ve iç tabaka için üç
adet kaplama olacak şekilde oluşturuldu. Üretilen LVL’ler kaplamaların kullanım
yeri ve türüne bağlı olarak kodlandırıldı. BBBBBBB, BBPPPBB, PPPPPPP ve PPBBBPP
sırasıyla I.grup, II. Grup, III. Grup ve IV. Grup olarak isimlendirildi.
Fiziksel özellikler olarak fırın Kurusu özgül ağırlık ve rutubet değerleri TS
2472 (1976a) ve TS 2471 (1976b) standartlarına göre belirlendi. Yapışma
mukavemeti, eğilme direnci, eğilmede elastikiyet modülü ve liflere paralel
basınç direnci gibi mekanik özellikler sırasıyla EN 314-1 (2004), EN310 (1993)
ve TS 2595 (1977) standartlarına göre belirlendi. Bu çalışmada en yüksek direnç
ve yoğunluk değeri tamamı kayın kaplamalarından üretilen I. Grup LVL’lerde elde
edildi. Diğer yandan en düşük değerler tamamı kavak kaplamalarından üretilen
III. Grup LVL’lerde gözlemlendi. Kayın kaplamalarının LVL’ ye katılım oranının
direnç ve yoğunluk değerlerinde bir artış sağladığı söylenebilir.

Abstract

Laminated Veneer Lumber (LVL) has been proven their usefulness and efficiency as framing members (girders, beams, joist, headers, panels, etc.)in construction. Their application and manufacture is limited in Turkey. In this study, four different types of 7-layers LVLs were successfully manufactured using sawed beech (B) and poplar (P) veneers, and melamine formaldehyde (MF) adhesive. In this work, LVLs were formed with two veneers for each surface and three veneers for core layer. Produced four different types of LVL were coded based on the type and location of the veneers. BBBBBBB, BBPPPBB, PPPPPPP and PPBBBPP were called as Group I, Group II, Group III and Group IV, respectively. As physical properties, oven dry specific gravity (SG) and moisture content (MC) were determined according to TS 2472 (1976a) and TS 2471 (1976b) standards. Mechanical properties like glueline shear strength, modulus of rupture (MOR), modulus of elasticity (MOE) and compression strength (CS)(parallel to grain) were also determined according to EN 314-1 (2004),EN310 (1993) and TS 2595 (Anonymous 1977)standards, respectively. Based on this study, the highest strength and SG values were obtained with all beech used veneers (Group I). On the other hand lowest values were recorded with all poplar veneers (Group III). It should be noted that contribution rate of beech veneers in LVL had an increase on both strength and SG values.
