    摘要:

    我国预应力工程进入国际市场日渐增多,国际预应力行业对结构上预应力锚固区承载性能都有标准要求,我国在这方面的研究恰是一个弱项。铸造型锚垫板和螺旋筋是夹片式锚具的组成部分,国际预应力协会(FIP)、欧洲标准(EN)及技术认证组织(EOTA)、美国国家公路和运输协会(AASHTO)及后张学会(PTI)都要求结合锚具在结构物上的排布进行试验认证,经认可的产品才允许在工程上实用。我国即将修订的锚具标准,也会有与之相当的规定。我国预应力锚具生产行业、结构设计单位和工程业主等部门很快就将面临此项复杂而又严格的陌生试验。本文作为锚固区安全探讨之六,将杭州浙锚预应力有限公司为主三年来摸索的试验方法,向同行人员作一个初步介绍,以响应我国新锚具标准的实施和开展此项试验认可工作。技术上不成熟之处在所难免,抛砖引玉,愿与同行专家共同探讨。

    Abstract:

    China's prestressed projects into the international market is increasing day by day, the international prestressed industry on the structure of the prestressed anchorage zone bearing performance have standard requirements, China's research in this area is just a weak point. The cast anchor plate and the spiral bar are part of the clip-on anchor, and the International Prestressing Association (FIP), the European Standards (EN) and Technical Certification Organization (EOTA), the American National Highway and Transportation Association (AASHTO) and the Post-Tensioning Institute (PTI) all require test certification combined with the arrangement of the anchor on the structure, and the approved product is allowed in the construction On the practical. China's upcoming revision of the anchor standard, there will be comparable provisions. China's prestressed anchor production industry, structural design units and project owners and other departments will soon face this complex and strict unfamiliar test. In this paper, as the sixth part of safety discussion in anchoring area, a preliminary introduction is made to the test methods explored by Hangzhou Zheanchou Prestressing Co., Ltd. in the past three years, in order to respond to the implementation of China's new anchor standard and carry out the test recognition work. Technical immaturity is inevitable, throw a brick to attract jade, willing to discuss with peer experts.
