PANEL ÇEŞİDİ, ARKALIK PANELİ VE FARKLI DUVAR MONTAJI UYGULAMALARINA GÖRE MUTFAK DOLAPLARININ MAKSİMUM YÜK TAŞIMA KAPASİTESİ

Öz

Bu çalışmada mutfak dolaplarının yük taşıma kapasitesi incelenmiş, deney örneği mutfak dolaplarında malzeme çeşitleri, duvar montaj yeri ve arka panel gibi faktörlerin  yük taşıma kapasitesi üzerindeki etkileri araştırılmıştır. Deney örneği mutfak dolapları 1/1 ölçekte hazırlanarak kalıcı deformasyona ulaşılıncaya kadar statik yük altında test edilmiştir.  Çalışmada, iki farklı duvar bağlantı noktası, yonga levha  (PB), lamine yonga levha (PB-m),  orta yoğunluklu lif levha (MDF) ve  lamine orta yoğunluklu lif levha (MDF-m) olmak üzere 4 farklı ahşap esaslı kompozit malzeme kullanılarak, dört elemanlı (arkalık paneli olmadan) ve beş elemanlı (arkalık panelli) toplam 48 mutfak dolabı üretilmiştir.. Tüm köşe bağlantıları 4 x 50 mm vidalar kullanılarak oluşturulmuştur. Tüm test numuneleri statik yük altında test edilmiş olup bir yükleme kayışı ile üst panelin yüzeyinden yükler uygulanmıştır.. Sonuç olarak, arkalık paneli olan mutfak dolaplarının, arkalık paneli olmayan mutfak dolaplarına kıyasla iki kat daha fazla yük taşıma kapasitesine sahip oldukları görülmüştür.  Mutfak dolaplarının yan panellerden duvara tutturulması için açılı metal konektörlerin yerleştirilmesi, sadece üst panelin değil, tüm yapının daha fazla yük taşımasına yardımcı olacağından; bu bağlantı elemanlarının kullanılması önerilmektedir. Ayrıca, Yongalevhadan üretilen mutfak dolapları,  MDF’den üretilen mutfak dolaplarının  mukavemetinin 2 / 3'üne sahip olduğu görülmüştür.

KITCHEN CABINETS MAXIMUM LOAD CARRYING CAPACITY BASED ON PANEL TYPES, USE OF BACK PANEL & WALL MOUNTING POINT CONDITIONS

Abstract

In this study, the maximum load carrying capacity of wall kitchen cabinets structure were investigated. Factors such as material types, wall mounting place and add of back panel on kitchen cabinets and their effect on the maximum load carrying capacity of the whole structure were investigated.  Kitchen cabinets were made in 1/1 scale and loaded until failure happened. For this purpose, a total of 48 kitchen cabinets were manufactured, including two different wall connection points, four different wood based panels, namely bare particleboard (PB), laminated particleboard (PB-m), bare medium density fiber board (MDF) and laminated medium density fiber board (MDF-m) which were used for construction of four and five member cabinets (with and without back panel). All corner joints were established by using 4 x 50 mm screws without adhesive. All test samples were tested under static load, loads were applied from the top panel’s surface by using a loading strap. According to the results, kitchen cabinets with the back panels compare to the same kitchen cabinets without back panels were able to carry two times more load.  Placement of angled metal connectors for attachment of these kitchen cabinets to the wall from side panels and not from the top panel can help the whole structure carry more load and therefor advised. Particleboard kitchen cabinets structures only had 2/3 of the strength of the corresponding MDF kitchen cabinets structures.
