1、专业工程管理与实务(建筑工程)(一级建造师)精讲班第26讲课件讲义（中国建造师考试网） 专业工程管理与实务(建筑工程)(一级建造师)精讲班第26讲讲义 第一段1A414072掌握玻璃幕墙工程施工的技术要求和方法 1A414072掌握玻璃幕墙工程施工的技术要求和方法 1A414073掌握金属与石材幕墙工程施工的技术要求和方法 【典型考题】隐框玻璃幕墙的硅酮结构密封胶粘结厚度应不小于（）。 A.4mm B.5mm C.6mm D.7mm 答案：C 解题思路：隐框、半隐框玻璃幕墙的硅酮结构密封胶粘结宽度和厚度应根据计算确定：厚度不应小于6mm，且不应大于12 mm；宽度不应小于7 mm，且不宜大于厚
2、度，也不宜大于厚度的2倍。所以正确选项为C。 【典型考题】常用建筑幕墙平板形预埋件中的锚板宜采用（）。 A.HPB235 B.HRB335 C.Q235 D.冷拉钢筋 答案：C 解题思路：常用建筑幕墙预埋件有平板形和槽形两种，其中平板形预埋件最为广泛应用。平板形预埋件的加工要求：锚板宜采用中的锚板宜采用Q235，锚筋宜采用HPB235、HRB335、HRB400级热轧钢筋，严禁使用冷加工钢筋。 【典型考题】金属与石材幕墙面板安装要求：金属板、石板安装时，左右、上下的偏差不应大于（）mm。 A.0.5 B.1.5 C.2.5 D.3.5 答案：B 解题思路：金属与石材幕墙面板安装要求：金属板、石
3、板安装时，左右、上下的偏差不应大于1。5mm；不锈钢挂件的厚度不宜小于3。0 mm，铝合金挂件的厚度不宜小于4。0 mm。所以正确选项为B。 【案例题】某开发区办公楼，剪力墙结构。因工程需要在其剪力墙的外侧安装玻璃幕墙。土建工程已经完毕，施工时没有预埋件，而且抹灰工序已经完成。现需要在该处安装后埋件，安装完毕后土建要对其进行抹灰和涂料处理。抹灰后后埋件不得外露。 在玻璃幕墙与每层楼板之间填充了防火材料，并用1.5mm厚的铝板固定。为了便于通风，防火材料与玻璃之间留有5mm的间隙。 问题： 1、安装后埋件前要对剪力墙该部位作什么处理？ 2、后埋件安装完毕后要做哪方面的检查工作？ 3、在安装玻璃之
4、前需要土建配合完成哪方面的工作？ 4、幕墙竣工后的三性试验是什么？ 5、防火材料的填充工艺是否合理？如有不妥的地方应如何处理？ 参考答案： 1、安装后埋件前需要把该处剪力墙的抹灰层打掉，后埋件必须与混凝土主体直接接触。后埋件安装后土建还要抹灰，而且后埋件的固定螺母不能外露，所以要计算后埋件厚度和螺母的高度之和。同时抹灰层对螺母外端还应该有一定的覆盖厚度，当抹灰层厚度满足不了以上要求时，就要把墙面剔进一定的深度，以保证后埋件安装完毕后，抹灰层能覆盖螺母并且不外露。 2、后埋件安装完毕以后要对螺栓（化学锚栓或膨胀螺栓）进行拉拔试验，试验的数据必须满足设计要求。同时还要对后埋件表面进行防腐处理。 3
5、、在安装玻璃幕墙之前需要土建完成抹灰和涂料工作，以免损伤和弄脏玻璃。 4、三性试验指：幕墙抗风压性能试验、幕墙空气渗透性能试验和幕墙雨水渗漏性能及平面变形性能试验。 5、（1）防火材料不能用铝板固定，因为铝板不耐高温，应该用1.5mm厚的镀锌钢板固定。（2）防火材料与玻璃、墙体之间不能留有间隙，必须安放严实。否则一旦起火，下层的浓烟便沿着间隙往上窜，失去了防火的作用。 【案例题】有一建筑工地，因设计变更需要在主体结构的某一处外侧增加幕墙，此时土建工程已经完毕，施工时没有预埋件，该处主体结构有如下几种形式：钢筋砼柱、钢筋砼梁、剪力墙、砖墙，而且外墙抹灰工序已经完成，现因工程需要安装后埋件，工人施
6、工时将后埋件直接埋在外墙上后进行立柱安装，最后通过施工验收，质量符合验收标准。 （问题） 1、以上所列几种主体结构形式有哪几种形式可以安装后埋件？ 2、安装后埋件之前需要对以上部位作何种处理？ 3、后埋件安装完毕后要做哪方面的测试工作？ 4、安装后埋件之后需要对后埋件的表面作何种处理？ 参考答案： 1、以上几种主体结构形式除砖墙以外其他结构形式都可以安装后埋件。 2、安装后埋件前需要把该处土建已经抹好的抹灰层打掉，后埋件必须与混凝土主体直接接触。 3、后埋件安装完毕以后要对化学锚栓（或膨胀螺栓）进行拉拔测试，其测试的数据必须满足设计要求。 4、后埋件安装好之后需要对后埋件的表面进行二次防腐处理
7、。 【案例题】有一幕墙工程，由一位刚从学校毕业的见习设计师设计，其中有大量不完善之处，试举典型立柱安装节点图（如下图）为例，请仔细看图，找出图中的错误之处，说明应该怎样改正，为什么？ 参考答案： 1、角钢、连接件、螺栓、螺母在固定好后都应进行焊接，因此图中相关部位都没有画出焊缝； 2、连接件与立柱连接时，应加防腐垫片，但不能加钢垫片； 3、立柱之间和玻璃板块之间不能打结构胶，应打耐候胶； 4、图中缺少预埋件，角钢是不能直接焊接在混凝土主体结构上的； 5、玻璃板块之间打耐候胶时，应填充聚乙烯发泡填料，以保证耐候胶的施工位置和防止形成三面粘结； 6、由于立柱为铝合金材料，因此与之连接的螺栓应采用不
