参见附图1-10,以下几个实施例给出了具有异形截面构造轻钢龙骨的复合墙体之说明。它是由复合墙体的内层1,具有异形截面构造的轻钢龙骨2,复合墙体的空心层3,复合墙体的外层4及对应网格构成的中空双层复合墙体。其中,如附图2-9所示,从墙体的稳固性考虑,实践中的轻钢龙骨,其截面构造特意设计成异形结构,这在本例中称之为异形截面构造的轻钢龙骨,其异型截面构造是指龙骨的截面形状是U型或C型,附图1所示的是具有异型截面构造的轻钢龙骨,分别设置在复合墙体的内、外层的内部,且与墙体等高。
实践中是将具有异形截面构造的轻钢龙骨(附图省略的)上下导轨、立柱按一定间距通过(附图省略的)螺丝或射钉固定成一框架结构并将框架设置在复合墙体中间,所述框架结构再通过(附图省略的)螺栓与建筑结构件梁、板及立柱安装固定,与建筑结构件合为一体。在轻钢龙骨(附图省略的)上下导轨、两侧立柱与建筑结构件梁、板及立柱接缝处,填如胶条、聚苯乙烯泡沫条、发泡条之类的密封材料。将网格用塑料铆钉固定在安装孔6、9上,用抹刀将石膏砂浆浆料抹在框架结构U型上下导轨及C型立柱的侧面上,使网格粘贴在框架结构上,形成一侧或两侧全部铺网的平面;或用抹刀将石膏砂浆浆料抹在框架结构U型上下导轨及C型立柱的侧面上并挤入安装孔6、9中,随后将网格铺贴其上并用抹刀压实,使网格粘贴在框架结构上,形成一侧或两侧全部铺网的平面;再将石膏砂浆喷筑在其上并将之包裹、覆盖,构成整体无缝隙的实心墙或空心墙或双层墙构造的复合墙体。
实践中的实心墙体是先将网格铺设在所述复合墙体的框架结构上,然后将石膏砂浆喷筑在网格及框架结构上,直至将网格及轻钢龙骨完全包裹、覆盖形成全填充的实心构造的复合墙体;或者,若将本例中的复合墙体做成空心墙体,则将石膏砂浆喷筑在所述框架结构的轻钢龙骨两侧的网格上,直至网格全部覆盖,形成以框架结构轻钢龙骨为中心、两侧墙体为实心的中空构造复合墙体;或者,如前例所述,实践中的双层墙体是先将石膏砂浆分别喷筑在墙体两侧(也可称之为内、外墙)的轻钢龙骨的网格上,将框架结构轻钢龙骨和网格完全包裹、覆盖,直至分别形成两面由单层框架结构轻钢龙骨和网格构成的实心墙体,再由这两面实心墙体构成的其层面之间为空心的双层墙体构造的复合墙体。
如前所述,为了提高墙体的稳定牢固性、安全保障性,本实施例刻意强调了如附图2-9所示的轻钢龙骨呈U型和C型的截面构造图;例如,C型轻钢龙骨截面凹台(或平台)5,C型轻钢龙骨截面凹台(或平台)安装孔6,C型轻钢龙骨截面凹槽透气孔7,U型轻钢龙骨截面凸槽8,U型轻钢龙骨截面凹台安装孔9,U型轻钢龙骨截面平台10;这些结构设计突显了轻钢龙骨U型和C型截面形状的特殊构造及对应孔、槽的位置。如此设计,可以大大提升墙体框架结构的抗扭曲性、稳定性和与各部件的紧密连结性。
根据装配式建筑的非承重墙的应力计算和应用场合,实践中所述的轻钢龙骨,其龙骨材质分别是热镀锌钢带、防火镀锌板、不锈钢、铝合金及PVC塑料;同时,为了便将网格固定于框架结构上,实践中另行设计了与安装孔配套的塑料铆钉配件。而实践用到的的网格,可以分别是玻纤网、尼 龙网、塑料网等非金属网。
针对实施例所说的复合墙体,具体的施工方法亦有具体的实施步骤:
(1)按墙体的设计位置放线;
(2)用膨胀螺丝或化学锚栓将U型异形截面构造的轻钢龙骨上下导轨固定于顶梁或板及楼、地板上;
(3)用自攻螺丝将C型异形截面构造的轻钢龙骨立柱与U型上下导轨固定,两侧C型立柱用膨胀螺丝或化学锚栓固定于建筑结构柱或墙上,形成一框架结构;
(4)在U型上下导轨与顶梁或板接缝处的凸槽处及两侧C型立柱与建筑结构件墙或柱接缝处塞入发泡条等弹性密封材料;
(5)将网格铺贴在所述轻钢龙骨上下导轨及立柱的侧面上,用塑料铆钉塞入安装孔中固定,再用抹刀将石膏砂浆浆料沿框架结构U型上下导轨及C型立柱的侧面涂抹,使网格粘贴在框架结构上,形成一侧或两侧全部铺网的平面;
或将工厂预混好的石膏砂浆加水搅拌成浆料,用抹刀将石膏砂浆浆料抹在框架结构U型上下导轨及C型立柱的侧面上并挤入安装孔中,随后将网格铺贴其上并用抹刀压实,使网格粘贴在框架结构上,形成一侧或两侧全部铺网的平面;
(6)待上述石膏砂浆浆料硬化后,用专用喷浆机在整体的网格上横向喷浆成条状或手工抹灰成条状,且保持条与条之间的间距具有一定距离,喷浆的厚度不能超过墙体的厚度;
(7)待上述条状石膏砂浆浆料硬化后,进行第一道墙面喷浆或手工抹 灰成墙;
(8)在喷筑复合墙体与建筑结构件接缝处,铺贴250mm宽度的网格布,防止接缝处开裂;
(9)在上述墙面上进行打点及冲筋,形成可最终控制墙面厚度的标筋;
(10)待标筋硬化后,再进行第二道喷墙并沿标筋方向刮平,形成达到抹灰找平效果的墙面;
(11)通过修补或打磨,使墙面达到可以验收的标准。
实践中,实施例所讲的具有异型截面构造的轻钢龙骨U型上下导轨及C型立柱、网格及石膏砂浆均在工厂制造,运抵现场组装;石膏砂浆采用袋装、吨袋装或散装方式运抵现场,经专用喷浆机自动加料、给水,搅拌及分层喷筑或手工抹灰成墙,硬化干燥后成为免抹灰的非承重隔墙。
实践中,复合墙体的制备方法中所说的建材,如具有异型截面构造的轻钢龙骨的导轨和立柱、网格和石膏砂浆的配料均可在工厂标准化定制,运抵现场组装;其中的石膏砂浆采用袋装、吨罐装或散装的方式运抵现场,经专用喷浆机自动加料、给水,搅拌及分层喷射砂浆成墙或手工抹灰成墙硬化,干燥后成为免抹灰的非承重隔墙。实践中,构成复合墙体的重要建材之一石膏砂浆是一种由工业副产石膏为原料制作的无机胶凝材料、以石英砂或玻化微珠、膨胀珍珠岩或其它材料为骨料,以其他矿物材料为填料与外加剂按一定配比在工厂混合生产成单一组份的干粉材料,将其运至施工现场建筑复合墙体时仅需加水搅拌即可使用。如此限定石膏砂浆的制作、调配,可以在保证环保的前提下大幅度降低制作成本,同时提升现场施工时的工程进度。
