题目内容

某工程项目模板支架在加载预压时垮塌,造成6人死亡、20人受伤的事故。事故调查组专家认为,事故的直接原因是:由于钢管立柱柱基不坚实,产生了一定的竖向和水平位移,桥梁施工直角制成体系侧向约束薄弱,在堆荷过程的外力作用下,由于支撑体系的局部变形引发支撑体系整体失稳破坏,造成支架垮塌事故。从现场观察和资料查阅情况看,支架体系在实施中存在以下主要问题:原设计单位要求的施工方案为满堂式支架,单位将满堂式支架的大部分改为贝雷支架,且未办理相关的更改和报批手续;对加载过程中引起的支架变形没有跟踪观测,不能适时了解支架加荷过程中的变形情况,以便及时发现险情并采用有效措施确保安全。加载过程带有盲目性,施工中对支架进行加载时现场较乱,未能按一定的顺序记加载。总而言之,这次事故是不完善的设计、不规范的施工作业,导致支架体系的失稳而垮塌。此次事故由县级安监部门负责组织调查。

B. 错误

背景 某公司新建一办公大楼,框架结构,烧结普通砖填充墙。 基础形式为大放脚基础,施工组织设计原定先采用机械开挖,然后人工清底至设计标高。实际土方开挖过程中,机械开挖由于在夜间施工,导致超挖0.2m深。 主体结构施工过程中,由于钢筋放样员识图错误,钢筋下料尺寸超出模板尺寸,需返工处理,施工单位拟将直径16mm以下的钢筋弯折处调直,然后重新加工制作。 屋面梁施工时,混凝土浇筑过后12d采用所有梁模板均拆除完毕,质量检查员发现部分梁出现比较大的孔洞。施工单位将孔洞冲洗干净后,用与梁浇筑时同等强度的混凝土进行填充捣实,并认真养护。 本工程外立面原设计为涂料饰面,主体结构施工完毕后,业主强行将设计更改为隐框玻璃幕墙。幕墙与主体结构采用后置埋件连接,因为幕墙构造需要,部分后置埋件连接位置在填充墙上。 普通砖墙上是否可作幕墙的支承点?如必须在砖墙上设置支承点,应采取什么措施?
