化学锚栓火灾情况下温度场试验分析

Testing Analysis on Temperature Field about Adhesive Anchor in Fire Condition

摘要: 化学锚栓大量应用于幕墙、机器安装以及建筑物加固、隧道工程、桥梁工程等。火灾情况下，化学锚栓的温度场是研究化学锚栓高温下承载能力的基础。本文按照我国现行的国家标准《建筑构件耐火试验方法第一部分：通用要求》GB/T 9978.1-2008中的标准升温曲线，对化学锚栓在火灾情况下的温度场进行了试验分析，得到在标准升温条件下的化学锚栓温度场情况。

Abstract: Adhesive anchor has been widely used in curtain wall, machine installation, building reinforce-ment, tunnel engineering and bridge engineering, etc. In fire case, the temperature field of the adhesive anchor is the base of the study of adhesive anchor’s bearing capacity. In this paper, according to the standard heating curve specified in current Chinese national standard “Fire-resistance tests-ele- ments of building construction—Part 1: General requirements GB/T 9978.1-2008 (ISO 834-1: 1999, MOD)”, some tests have been carried out about Adhesive anchor. Analyzing the experimental data, we got the temperature field about Adhesive anchor in fire condition.
