Description

一种高强度轻质复合墙板及其墙体系统 技术领域
本发明涉及建筑材料技术领域，尤其涉及一种适用于快速工业化干作业施工的高强度轻质复合墙板及其墙体系统。
背景技术
随着经济水平的提高和城市化进程的加快，整个社会的建筑规模越来越大，这对施工效率提出了更高的要求。新型的轻质保温墙板材料逐渐取代传统的黏土砖、陶粒混凝土砌块等材料，成为现代建筑领域中越来越受欢迎的主流墙板材料。
目前，常用的轻质墙板材料是通过轻质混凝土加聚苯乙烯颗粒浇筑成聚苯颗粒泡沫混凝土板，然后在聚苯颗粒泡沫混凝土板两侧通过水泥木丝板封面而成。此类轻质墙板材料具有保温、隔热、隔声、重量轻、满足甲级防火标准等优点，因此被广泛采用。
但本申请发明人在实现本申请实施例中发明技术方案的过程中，发现上述技术至少存在如下技术问题：
1、现有聚苯颗粒泡沫混凝土板，主体材质为轻质(泡沫)混凝土，该材质具有松软易碎的缺陷，所制成的墙板强度有限，不适用于强度要求高的建筑工况。
2、聚苯颗粒泡沫混凝土板与水泥木丝板是通过水泥木丝板的自粘性连接，但水泥木丝板的粘性不高，在使用过程中，会出现聚苯颗粒泡沫混凝土板与水泥木丝板封面的脱离，影响墙体的使用，墙体的质量有待提高。
3、现有聚苯颗粒泡沫混凝土板施工时，只能用轻质混凝土加聚苯乙烯颗粒现场浇填于建筑物钢梁或钢柱的空隙中，表层再用无纺布或网布贴着把水泥木丝板封面涂抹平整，实现聚苯颗粒泡沫混凝土板与建筑物钢梁或钢柱的固定。即现有的聚苯颗粒泡沫混凝土板只能适用于湿作业，这大大提高了现场施工的人力成本，需要很长的施工时间，不能满足日益提高的建筑集成化及高效率施工的要求。
4、现有的聚苯颗粒泡沫混凝土板，只能一次性使用，在安装完成后，不可拆除后重复利用，易产生大量建筑垃圾，造成资源浪费，不符合现代社会所倡导的绿色环保和文明施工的要求。

具体实施方式
本申请实施例通过提供一种高强度轻质复合墙板及其墙体系统，解决了现有技术中聚苯颗粒泡沫混凝土板松软易碎、质量欠佳、只能适用于湿作业、人力成本高、施工效率低、只能一次性使用的技术问题，使墙板的强度和质量大大提高，适用于快速工业化干作业施工，大大降低了劳动力成本，满足快速、精密、高效施工的要求，且可以拆除后重复利用。
本申请实施例中的技术方案为解决上述串扰的问题，总体思路如下：
基于现有的聚苯颗粒泡沫混凝土板，在聚苯颗粒泡沫混凝土板浇筑时左右两侧加装C型钢板封头，然后再在聚苯颗粒泡沫混凝土板前后两侧加装水泥木丝板封面。聚苯颗粒泡沫混凝土板与水泥木丝板封面不仅通过水泥木丝板的自粘性连接，还通过射钉将水泥木丝板与墙板两侧的C型钢板封头连接，如此加固了整个墙板的强度。
由于在墙板两侧加装了C型钢板封头，整个墙板的强度得到提高。同时，墙板和建筑物钢梁或钢柱连接时，直接用螺栓将墙板侧面的C型钢板封头固定在钢梁或钢柱上即可，连接方便、快速，真正做到了干作业，快速工业化施工。 突破了传统聚苯颗粒泡沫混凝土板松软易碎、只能适用于湿作业的局限。
相邻两块墙板通过C型钢板封头连接，拼接成大面积墙体。优选地，在墙板两端设计公母企口的C型钢板封头，相邻两块墙板通过公母企口的C型钢板封头连接，并用螺钉将互相连接的两个C型钢板封头的公母企口处固定，如此，不仅可以实现墙板的定位连接，还可以增强墙体系统的抗扭强度。
上述结构的墙板适用于内墙板。当用作外墙板时，再在上述结构的墙板顶部预制砼封堵块，在相邻两块墙板之间加装隔水条，达到保温、隔热、隔声、防水、重量轻、满足甲级防火标准等有益效果。
此外，在安装使用完成后，本申请实施例提供的墙板可以拆除后重复利用，不会产生建筑垃圾，节约了资源，符合现代社会所倡导的绿色环保和文明施工的要求。
为了更好的理解上述技术方案，下面将结合说明书附图以及具体的实施方式对上述技术方案进行详细的说明。
实施例一
图1～图3分别为本实施例中提供的高强度轻质复合内墙板的整体结构示意图、爆炸图和剖面图，所述的高强度轻质复合内墙板由聚苯颗粒泡沫混凝土板1、C型钢板封头2、水泥木丝板3、射钉4等部件组成。
其中，聚苯颗粒泡沫混凝土板1是通过轻质混凝土加聚苯乙烯颗粒浇筑而成。市面上有很多这种材质的板，如：上海康尼建材科技有限公司生产的“康尼板”，广东松本绿色板业股份有限公司生产的“松本板”等。聚苯颗粒泡沫混凝土板1的容重小于800kg/m 3，具有保温、隔热、隔声、重量轻、满足甲级防火标准等优点。
结合图4，C型钢板封头2包括主封面侧板21，主封面侧板21的一端垂直连接第一水平钢板22的一端，第一水平钢板22的另一端向内侧折弯形成第一辅助侧板23，第一辅助侧板23的尾部向内侧折弯形成第一倒勾24；主封面侧板21的另一端垂直连接第二水平钢板25的一端，第二水平钢板25的另一端向内侧折弯形成第二辅助侧板26，第二辅助侧板26的尾部向内侧折弯形成第二倒勾27。C型钢板封头2为对称结构。
聚苯颗粒泡沫混凝土板1的左右两侧(厚度方向)固定C型钢板封头2。C型钢板封头2的主封面侧板21设于聚苯颗粒泡沫混凝土板1的侧面，第一水平 钢板22、第二水平钢板25分别贴紧聚苯颗粒泡沫混凝土板1的前、后表面，第一辅助侧板23及第一倒勾24、第二辅助侧板26及第二倒勾27均镶嵌于聚苯颗粒泡沫混凝土板1内部。
聚苯颗粒泡沫混凝土板1的前后两侧(宽度方向)固定水泥木丝板3作为封面。前、后两侧的水泥木丝板3分别与C型钢板封头2的第一水平钢板22、第二水平钢板25紧贴，并通过射钉4固定。连接处，前、后两侧的水泥木丝板3分别位于第一水平钢板22、第二水平钢板25的外侧。
浇筑的时候，聚苯颗粒泡沫混凝土、C型钢板封头2、水泥木丝板3均放置于模具内，一体浇筑成型。水泥木丝板3本身具有自粘性，粘贴于聚苯颗粒泡沫混凝土板1的表面，同时通过射钉4将水泥木丝板3与两侧的C型钢板封头2连接固定，如此进一步加固了整个墙板的强度，保证墙板使用过程中，水泥木丝板3不会脱落。
本实施例中提供的高强度轻质复合内墙板可以预先制作多个模块，然后运输至施工现场进行拼装。拼装时，相邻两块内墙板的C型钢板封头2的主封面侧板21对齐紧贴，并通过螺钉5固定，拼接成大面积的内墙体，如图5所示。
本实施例中提供的高强度轻质复合内墙板与施工现场的建筑物钢柱7连接时，直接用螺栓6将内墙板侧面的C型钢板封头2的主封面侧板21固定在H型的钢柱7上即可，如图6所示。内墙板与钢柱的连接方便、快速，真正做到了干作业，快速工业化施工，突破了传统聚苯颗粒泡沫混凝土板松软易碎、且只能适用于湿作业的局限性。
本实施例中提供的高强度轻质复合内墙板的厚度一般为10cm左右，根据具体的使用工况，可以适当调整。
本实施例中提供的高强度轻质复合内墙板构成的墙体系统与传统的轻质墙体系统相比具有明显的优势：
1、材料成本明显降低。传统的轻质墙体系统由G550轻钢、岩棉及辅料等组成，本实施例墙体系统的材料成本相比传统的轻质墙体系统明显降低。
2、安装成本明显降低。传统的轻质墙体系统由多种材料叠层而成，操作较为复杂，安装时间长，安装成本高；本实施例墙体系统由高强度轻质复合墙板直接拼装而成，集成度高，操作简单快捷，安装成本低。本实施例墙体系统的安装成本不到传统的轻质墙体系统的三分一。
3、安装效率明显提高。基于一个装满高强度轻质复合内墙板(120mm厚)的集装箱(11.88m*2.32m*2.55m)的面积(259.2m 2)为基数，以259.2平米的内墙为例，传统的轻质墙体系统需要12个工人20天时间完成，本实施例墙体系统进需要6个工人10天时间完成。
值得说明的是，根据不同的使用工况，本实施例中的聚苯颗粒泡沫混凝土板1也可以替换为其它的轻质墙体芯板，本实施例中的水泥木丝板3也可以替换为其它的封面。
上述本申请实施例中的技术方案，至少具有如下的技术效果或优点：
1、通过在内墙板两侧加装C型钢板封头，解决了现有的聚苯颗粒泡沫混凝土板松软易碎的问题，所制成的内墙板强度大大提高，适用于强度要求高的建筑工况。
2、通过在内墙板两侧加装C型钢板封头，内墙板和建筑物钢梁或钢柱连接时，直接用螺栓将内墙板侧面的C型钢板封头固定在钢梁或钢柱上即可，连接方便、快速，真正做到了干作业，快速工业化施工。
3、通过在内墙板两侧加装C型钢板封头，相邻两块内墙板拼装时，将相邻两块内墙板的C型钢板封头对齐紧贴，并通过螺钉固定，即可拼接成大面积的内墙体。
4、聚苯颗粒泡沫混凝土板与两个水泥木丝板封面之间不仅通过水泥木丝板的自粘性连接，还通过射钉将水泥木丝板与内墙板两侧的C型钢板封头连接，如此加固了整个内墙板的连接强度，水泥木丝板在使用过程不会脱落，保证了内墙体的使用质量。
5、本申请实施例提供的高强度轻质复合内墙板，可以模块式预先制作好，到施工现场拼装连接即可，适用于快速工业化干作业施工，大大降低了劳动力成本，满足快速、精密、高效施工的要求，推进了建筑工业化的进程，具有广泛的应用前景。
6、本申请实施例提供的高强度轻质复合内墙板，在安装使用完成后，可以拆除后重复利用，不会产生建筑垃圾，节约了资源，符合现代社会所倡导的绿色环保和文明施工的要求。
实施例二
图7～图9分别为本实施例中提供的高强度轻质复合内墙板的整体结构示意 图、爆炸图和剖面图，所述的高强度轻质复合内墙板与实施例一大体相同，其区别仅在于将实施例一中左右两侧的C型钢板封头2的主封面侧板21分别设计为具有公母企口。本实施例中，公母企口是通过将主封面侧板折弯成阶梯台阶状构成。
如图10所示，C型钢板封头2包括第一阶梯侧板211，第一阶梯侧板211一端连接阶梯水平钢板212一端，阶梯水平钢板212另一端连接第二阶梯侧板213一端；第一阶梯侧板211的另一端端垂直连接第一水平钢板22的一端，第一水平钢板22的另一端向内侧折弯形成第一辅助侧板23，第一辅助侧板23的尾部向内侧折弯形成第一倒勾24；第二阶梯侧板213的另一端端垂直连接第二水平钢板25的一端，第二水平钢板25的另一端向内侧折弯形成第二辅助侧板26，第二辅助侧板26的尾部向内侧折弯形成第二倒勾27。
聚苯颗粒泡沫混凝土板左右两侧的C型钢板封头2的结构对应设置，右侧的C型钢板封头2由左侧的C型钢板封头2水平翻转再垂直翻转构成。即：一侧的C型钢板封头2为上凹下凸，另一侧的C型钢板封头2为上凸下凹。
内墙体拼接时，相邻两块内墙板通过具有公母企口的C型钢板封头连接，并将互相连接的两个C型钢板封头的公母企口处(本实施例中为阶梯水平钢板212处)通过螺钉5固定，如图11所示，如此，不仅可以实现内墙板的定位连接，还可以增强内墙体的抗扭强度。
本实施例中提供的高强度轻质复合内墙板与施工现场的建筑物钢柱7连接时，直接用螺栓6将内墙板侧面的C型钢板封头2固定在钢柱7上即可，端部的与H型的钢柱7连接的C型钢板封头不需要设置公母企口，该C型钢板封头与钢柱5连接的面设置为与实施例一中一样的普通的平面即可，如图12所示。
上述本申请实施例中的技术方案，除了具有实施例一的有益效果外，至少还具有如下的技术效果或优点：
通过在内墙板两侧设计公母企口的C型钢板封头，相邻两块内墙板通过公母企口的C型钢板封头连接，并用螺钉将互相连接的两个C型钢板封头的公母企口处固定，如此，不仅可以实现内墙板的定位连接，还可以增强内墙体系统的抗扭强度。
实施例三
图13～图15分别为本实施例中提供的高强度轻质复合外墙板的整体结构示 意图、爆炸图和剖面图，所述的高强度轻质复合内墙板由聚苯颗粒泡沫混凝土板1、C型钢板封头2、水泥木丝板3、射钉4、砼封堵块8、隔水条9等部件组成。
其中，聚苯颗粒泡沫混凝土板1是通过轻质混凝土加聚苯乙烯颗粒浇筑而成。市面上有很多这种材质的板，如：上海康尼建材科技有限公司生产的“康尼板”，广东松本绿色板业股份有限公司生产的“松本板”等。聚苯颗粒泡沫混凝土板1的容重小于800kg/m 3，具有保温、隔热、隔声、重量轻、满足甲级防火标准等优点。
聚苯颗粒泡沫混凝土板1的左右两侧(厚度方向)固定C型钢板封头2，聚苯颗粒泡沫混凝土板1的前后两侧(宽度方向)固定水泥木丝板3作为封面。水泥木丝板3与C型钢板封头2连接处，水泥木丝板3位于C型钢板封头2外侧，并通过射钉4固定。
如图16所示，C型钢板封头2包括侧面钢板20，侧面钢板20的一端垂直连接第一水平钢板22的一端，第一水平钢板22的另一端向内折弯形成第一辅助侧板23，第一辅助侧板23的尾部向内侧折弯形成第一倒勾24；侧面钢板20的另一端垂直连接第二水平钢板25的一端，第二水平钢板25的另一端向内折弯形成第二辅助侧板26，第二辅助侧板26的尾部向内侧折弯形成第二倒勾27。
两侧的C型钢板封头2的侧面钢板20上分别设置有公母企口，本实施例中，公母企口为匹配设置的凹凸结构。侧面钢板20的中心设置隔水条安装槽28，用于固定隔水条9。隔水条9为橡胶条，用于实现相邻两块外墙板的C型钢板封头2的密封防水连接。
砼封堵块8固定于聚苯颗粒泡沫混凝土板1的顶部，同时覆盖C型钢板封头2的顶部和水泥木丝板3的顶部，并压住隔水条9。
浇筑的时候，聚苯颗粒泡沫混凝土、C型钢板封头、隔水条、水泥木丝板、砼封堵块均放置于模具内，一体浇筑成型。在聚苯颗粒泡沫混凝土凝结过程中，砼封堵块与聚苯颗粒泡沫混凝土板身凝在一起，形成高强度的外墙板。
本实施例中，砼封堵块8为预制好的，设置砼封堵块8有以下两个作用：一、砼封堵块8用的砼比聚苯颗粒泡沫混凝土板1的标号高，隔水条9被精致的砼封堵块8压住，整个墙板的密封性得到保证。二、灌注聚苯颗粒泡沫混凝土时，工艺上先将底部模具与四周构件搭配固定，从顶上开口灌注，过程中有泡沫及一定的臌涨，用精致的预制好的砼封堵块8插入封头可以解决气泡及膨涨时的收头边 缘的毛糙。而墙板底部因有模具限定，通过重力作用，收边自然平整，因此无需再设置砼封堵块。
水泥木丝板3本身具有自粘性，粘贴于聚苯颗粒泡沫混凝土板1的表面，同时通过射钉4将水泥木丝板3与两侧的C型钢板封头2连接固定，如此进一步加固了整个外墙板的强度，保证外墙板在使用过程中，水泥木丝板3不会脱落。
本实施例中提供的高强度轻质复合外墙板可以预先制作多个模块，然后运输至施工现场进行拼装。拼装时，相邻两块外墙板的C型钢板封头2的侧面钢板20的公母企口匹配紧贴，并在相邻两块外墙板的C型钢板封头之间的隔水条安装槽28内加装隔水条9，然后通过螺钉5将相邻两块外墙板的C型钢板封头的侧面钢板20固定，拼接成大面积的外墙体，如图17所示。
本实施例中提供的高强度轻质复合内墙板与施工现场的建筑物钢柱7连接时，用螺栓6依次穿过钢柱7、水泥木丝板3、C型钢板封头2的第一水平钢板22或第二水平钢板25并固定，如图17所示。外墙板与钢柱的连接方便、快速，真正做到了干作业，快速工业化施工，突破了传统聚苯颗粒泡沫混凝土板松软易碎、只能适用于湿作业的局限。
针对有窗户设置的地方，则外墙板的该侧的C型钢板封头2的侧面钢板20上不设置公母企口，直接设置为平面即可，如图18所示。
本实施例中提供的高强度轻质复合外墙板的厚度一般为15.2cm左右，根据具体的使用工况，可以适当调整。
值得说明的是，根据不同的使用工况，本实施例中的聚苯颗粒泡沫混凝土板1也可以替换为其它的轻质墙体芯板，本实施例中的水泥木丝板3也可以替换为其它的封面。
上述本申请实施例中的技术方案，至少具有如下的技术效果或优点：
1、通过在外墙板两侧加装C型钢板封头，解决了现有的聚苯颗粒泡沫混凝土板松软易碎的问题，所制成的外墙板强度大大提高，适用于强度要求高的建筑工况。
2、通过在外墙板两侧加装C型钢板封头，外墙板和建筑物钢梁或钢柱连接时，直接用螺栓将外墙板侧面的C型钢板封头固定在钢梁或钢柱上即可，连接方便、快速，真正做到了干作业，快速工业化施工。
3、相邻两块外墙板通过公母企口的C型钢板封头连接，并用螺钉将互相连 接的两个C型钢板封头的公母企口处固定，如此，不仅可以实现外墙板的定位连接，还可以增强外墙体的抗扭强度。
4、在C型钢板封头外侧加装隔水条，相邻两块外墙板拼装时，通过螺栓将C型钢板封头密封固定，中间夹设隔水条，即可拼接成大面积的具有防水功能的外墙体，提高了墙体的防水性能。
5、在外墙板顶部设有预制的砼封堵块，隔水条被精致的砼封堵块压住，整个墙板的密封性得到保证；同时灌注聚苯颗粒泡沫混凝土时，工艺上先将底部模具与四周构件搭配固定，从顶上开口灌注，过程中有泡沫及一定的臌涨，用精致的预制好的砼封堵块插入封头可以解决气泡及膨涨时的收头边缘的毛糙，得到平整、精致、美观的外墙板。
6、聚苯颗粒泡沫混凝土板与两个水泥木丝板封面之间不仅通过水泥木丝板的自粘性连接，还通过射钉将水泥木丝板与外墙板两侧的C型钢板封头连接，如此加固了整个外墙板的连接强度，水泥木丝板在使用过程不会脱落，保证了外墙体的使用质量。
7、本申请实施例提供的高强度轻质复合外墙板，可以模块式预先制作好，到施工现场拼装连接即可，适用于快速工业化干作业施工，大大降低了劳动力成本，满足快速、精密、高效施工的要求，推进了建筑工业化的进程，具有广泛的应用前景。
8、本申请实施例提供的高强度轻质复合外墙板，在安装使用完成后，可以拆除后重复利用，不会产生建筑垃圾，节约了资源，符合现代社会所倡导的绿色环保和文明施工的要求。
