摘要
汶川地震以后,利用预制楼板作为水平承重结构的建筑抗震性能和加固措施再次成为学者们研究的课题,目前对于预制楼板的抗震加固设计普遍采用的是钢板支撑预制楼板结合钢筋混凝土叠合板或者底部粘贴碳纤维布的加固方法。文章结合一中学校舍的加固设计方案,探讨了钢板支撑预制楼板加固施工中的措施,总结了施工中存在的问题和解决的一般措施。希望对钢板支撑预制楼板加固施工能起到一定的借鉴意义。
After the massive earthquake in Wenchuan,the research about seismic performance and reinforcement measure of building using precast floor slab as a horizontal bearing structure becomes a hot topic again.At present,the designs of precast floor strengthening are widely used steel plate supporting at the bottom of precast floor combining with reinforced concrete composite or CFRP pasted. The paper discusses on strengthening construction measures for angle steel support precast floor slab combining with reinforcement design scheme of secondary school buildings,problems existing in the construction are put forward, and the construction experiences are summed up. This precast floor slab strengthening work could play a certain role.
