问题 问答题

【背景材料】

某建筑公司承接一项综合楼任务,建筑面积100 828m2,地下3层,地上26层,箱形基础,主体为框架结构。该项目地处城市主要街道交叉路口,是该地区的标志性建筑物。因此,施工单位在施工过程中加强了对工序质量的控制。在第5层楼板钢筋隐蔽工程验收时发现整个楼板受力钢筋型号不对、位置放置错误,施工单位非常重视,及时进行了返工处理,在第10层混凝土部分试块检测时发现强度达不到设计要求,但实体经有资质的检测单位检测鉴定,强度达到了要求。由于加强了预防和检查,没有再发生类似情况。该楼最终顺利完工,达到验收条件后,建设单位组织了竣工验收。

【问题】

1.工序质量控制的内容有哪些?

2.说出第5层钢筋隐蔽工程验收的要点。

3.第10层的质量问题是否需要处理?请说明理由。

4.如果第10层混凝土强度经检测达不到要求,施工单位应如何处理?

5.该综合楼达到什么条件后方可竣工验收?

答案

参考答案:

1.工序质量控制的内容包括:严格遵守工艺规程;主动控制工序活动条件的质量;及时检查工序活动效果的质量;设置工序质量控制点。

2.第5层楼板钢筋隐蔽验收要点。

(1)按施工图核查纵向受力钢筋,检查钢筋的品种、规格、数量、位置、间距、形状。

(2)检查混凝土保护层厚度,构造钢筋是否符合构造要求。

(3)钢筋锚固长度,箍筋加密区及加密间距。

(4)检查钢筋接头,如绑扎搭接,要检查搭接长度,接头位置和数量(错开长度、接头百分率);焊接接头或机械连接,要检查外观质量,取样试件力学性能试验是否达到要求,接头位置(相互错开)数量(接头百分率)。

3.第10层的混凝土不需要处理混凝土,试块检测强度不足后对工程实体混凝土进行的测试证明能够达到设计强度要求,故不需进行处理。

4.如果第10层实体混凝土强度经检测达不到设计强度要求,应按如下程序处理。

(1)施工单位应将试块检测和实体检测情况向监理单位和建设单位报告。

(2)由原设计单位进行核算。经设计单位核算混凝土强度,若能满足结构安全和工程使用功能,可予以验收;如经设计单位核算混凝土强度不能满足要求,需根据混凝土实际强度情况制定拆除、重建、加固补强、结构卸荷、限制使用等相应的处理方案。

(3)施工单位按批准的处理方案进行处理。

(4)施工单位将处理结果报请监理单位进行检查验收报告。

(5)施工单位对发生的质量事故剖析原因,采取预防措施予以防范。

5.该综合楼工程应达到下列条件,方可竣工验收。

(1)完成建设工程设计和合同规定的内容。

(2)有完整的技术档案和施工管理资料。

(3)有工程使用的主要建筑材料、建筑构配件和设备的进场试验报告。

(4)有勘查、设计、施工、工程监理等单位分别签署的质量合格文件。

按设计内容完成,工程质量和使用功能符合规范规定的设计要求,并按合同规定完成了协议内容。

Last summer my family moved to a new neighborhood. Ramon, a boy living right across the street from our new house, came by to ___小题1:___ hello. When school started, I was happy that Ramon was in my class. One day Mr. Rosen, our teacher, told us about the big Art and Music Festival coming up at school. He said, “Who wants to be in the show? Raise your hands.” The class became restless. About a dozen hands went up. I started to raise my hand, ___小题2:___ I stopped and put it down. I couldn’t say a word. I just sat there while the others volunteered. “There is a piano in the hall. We could use a piano player,” said Mr. Rosen. Still I said nothing. And ___小题3:___ asked me to perform at the festival, for I had never even told anyone that I could play the piano. Every day when I went home to learn the sonata in C Major(C 大调奏鸣曲) by Mozart , I told Ramon I had to do my homework. Every day it ___小题4:___ better and better and I grew more and more disappointed that I had not ___小题5:___ to play at the festival. One afternoon I was practicing as usual. Suddenly there was a ___小题6:___ at the door. I was in the middle of Mozart’s Sonata, so I kept on playing. My mom opened the door and told me it was Ramon. “What nice ___小题7:__! ” I heard him say. Then he walked into the living room and saw me ___小题8:___ the piano. When I finished, Ramon jumped up and clapped. He ran over to me and gave me a pat on the back. “Matthew,” he said, “that was great! I never even knew you could play the piano! ___小题9:___ were you keeping this a secret?” I kept quiet for a minute. I felt foolish. Ramon had stopped by to borrow my math book because he had left his at school ___小题10:__ mistake. Now he knew I played the piano. The next day in school, Ramon told Mr. Rosen that I was a great pianist. The rest is history.
