[提要]  混凝土結(jié)構(gòu)植筋錨固的使用受多種因素制約，植筋錨固材料的耐久性、穩(wěn)定性、耐火性、使用部位、鋼筋錨固長(zhǎng)度、錨固區(qū)混凝土的約束等在設(shè)計(jì)時(shí)都應(yīng)慎重考慮。文中還對(duì)專(zhuān)用水泥的部頒標(biāo)準(zhǔn)《無(wú)收縮快硬硅酸鹽水泥》( ZBQ11009-88)配制的漿錨砂漿用于鋼筋鋪固、搭接的試驗(yàn)研究做了介紹。

Glued joints for steel bars applied in concrete structure are limited by many factors, including fire resistance and stability, position in the structure, anchorage length of steel bars, confinement of concrete, which should be considered when designing. In addition, this paper introduces the mortar of glued joints mixed with Non-shrinkage quick-harcl ening Portland cement ( ZBQ11009-88) and the experimental research of its application in anchorage of steel bars and lapped splices.
Keywords:  glued joints; fire resistance; anchorage length; steel bar; concrete; limit anchor area; mortar
