Abstract

The increasing demands and needs of human beings reveal the need to increase the performance of construction techniques and materials in the construction sector. Recently, the use of ultra high performance concrete (UHPC) on building facades has been increasing due to their superior mechanical and physical properties. Since UHPC products are relatively heavy, it is important to examine the lifting apparatuses for safety. In this study, pull-out and shear behavior of lifting sockets embedded in UHP precast panels produced in real geometry and dimensions were investigated. UHPCs consist of two different mixtures as A and B. Two different types of lifting sockets with the trade names RD and TF were used. Pull-out and shear test results proved that lifting sockets are sufficient as safety in both mixtures. The results obtained can contribute to the literature in this area and provide insight into the reliable lifting and handling procedure of precast facade panels.

Özet

İnsanoğlunun artan istek ve ihtiyaçları, inşaat sektöründe yapı teknikleri ve malzemelerinin performansının artırılması ihtiyacını ortaya koymaktadır. Son zamanlarda, bina cephelerinde ultra yüksek performanslı beton (UHPC) kullanımı üstün mekanik ve fiziksel özellikleri nedeniyle artmaktadır. UHPC ürünleri nispeten ağır olduklarından dolayı kaldırma aparatlarının güvenlik açısından incelenmesi önem arz etmektedir. Bu çalışmada gerçek geometri ve boyutlarda üretilen UHPC prekast panellerine gömülü olan kaldırma soketlerinin çekme-çıkarma ve kesme kuvvetlerine karşı davranışları incelenmiştir. UHPC paneller A ve B olmak üzere iki farklı karışımdan elde edilmiştir. Ticari isimleri RD ve TF olan iki farklı tip kaldırma soketi kullanılmıştır. Çekme-çıkarma ve kesme test sonuçları kaldırma soketlerinin her iki karışımda da güvenlik açısından yeterli olduğunu kanıtlamıştır. Elde edilen sonuçlar, literatüre bu alanda katkı sağlayabilir ve prekast cephe panellerinin güvenilir bir şekilde kaldırma ve taşıma prosedüründe fikir oluşturabilir.
