什么是粘接型锚栓(化学锚栓)?
What is Adhesive Anchor(Chemical Anchor)?
关于粘接型锚栓(化学锚栓)的定义,让我们先从国外的定义开始理解吧。
(1)美国(由 ACI 318 - 11 Appendix D 定义)
Adhesive Anchor - A post-installed anchor, inserted into hardened concrete with an anchor hole diameter not greater than 1.5 times the anchor diameter, that transfers loads to the concrete by bond between the anchor and the adhesive, and bond between the adhesive and the concrete.
Adhesive - Chemical components formulated from organic polymers, or a combination of organic polymers and inorganic materials that cure when blended together.
(2)欧洲(由ETAG-001-PART-1-GENERAL-2013-04-08定义)
Bonded anchors (Figure 2.2d) are anchored in drilled holes by bonding the metal parts to the sides of the drilled hole with a mortar (e.g. resin mortar). Tensile loads are transmitted to the concrete via bond stresses between the metal parts and the mortar and the mortar and the concrete face of the drilled hole.

只看楼主 我来说两句这完全是国内的机关,协助MKT、慧鱼等欧洲公司搞出来的指鹿为马的大骗术。更要命的是设计院的大师们还照写不误,像是真事儿似的。
简单的理解,特殊倒锥形化学锚栓的承载力理论上会完全低于普通化学。
