随着预应力材料的发展,一种新的预应力钢筋材料——高强PC钢棒问世。由于具有环保和性价比高等特点,高强PC钢棒先张、后张预应力板、梁在预应力混凝土结构中也开始大量应用,这就迫切地需要一种适用于此类预应力钢筋的锚具和夹具产品。本文主要介绍了建研科技股份有限公司高强PC钢棒用锚具和夹具的研究与试验。
With the development of prestressed materials, a new prestressed reinforced material - high strength PC steel bar is available. Due to the characteristics of environmental protection and high cost performance, high-strength PC steel bars pre-tensioned, post-tensioned prestressed concrete slab, beams also began to be widely used in prestressed concrete structures, which urgently needed an anchor suitable for such prestressed reinforcement And fixture products. This article mainly introduces the research and experiment of the anchors and fixtures for high strength PC steel bars of Jiangyan Science and Technology Co., Ltd.
