背景

某施工单位承建了天津市某医院门诊楼工程。地下2层、地上16层，钢筋混凝土筏板基础，地上结构为钢筋混凝土框架结构，墙充填为普通混凝土小型空心砌块。施工过程中发生如下事件：

事件一：本工程基坑深8.5m，北侧紧邻某住宅楼。经专家论证后的方案采用围护桩墙+预应力锚杆支护体系。整个施工过程对围护体系实施连续变形监控，对于围护桩墙顶位移监控值，施工单位与监理发生分歧，施工单位认为按二级基坑监控，监理坚持按一级基坑进行监控。

事件二：基础工程施工完成后，在施工单位自检合格、总监理工程师签署“质量控制资料符合要求”审查意见的基础上，施工单位项目经理组织项目技术、质量负责人、总监理工程师进行了地基与基础分部工程的验收。

事件三：普通混凝土小型空心砌块墙体施工时，施工人员先将小砌块充分浇水湿润，再将砌块底面朝上反砌于墙上；外墙转角处的临时间断处留直槎，并砌成阴阳槎，并设拉结筋。监理工程师认为施工方法错误，立即下发了整改通知。

事件四：地上框架结构存在主次梁，在主次梁交汇处，关于钢筋摆放上下顺序监理与施工技术员在理解上发生分歧，随后上报总监理工程师处理。

请给出事件四中主梁、次梁、板钢筋的上下放置正确顺序。
