Description

一种带肋网架叠合墙构造及施工方法
技术领域
本发明涉及一种网架叠合墙,具体是一种带肋网架叠合墙构造及施工方法。
背景技术
目前建筑物外墙采用钢筋混凝土预制构件时,基本采用混凝土夹心墙全部预制的工艺。但该工艺结构层的钢筋和混凝土预制完毕后,连接时钢筋不能实现全部的搭接连接,对建筑物的整体结构安全可能带来不安全隐患。采取不受力的构造层预制、结构层现浇,虽然能够解决上述问题且节约外侧浇筑模板,但是构造层较薄,抗折强度较低,在生产、运输、安装过程中容易产生折断等质量通病,严重影响工期。全部采用轻骨料混凝土虽能减轻构件自重,但是耐久性又相对较差。
发明内容
本发明的目的在于提供一种带肋网架叠合墙构造及施工方法,以解决上述背景技术中提出的问题。
为实现上述目的,本发明提供如下技术方案:
一种带肋网架叠合墙构造,包括预制单元,预制单元包括混凝土预制构造层、保温层和钢筋焊接网架板,混凝土预制构造层带有竖向或横竖双向的嵌入保温层内的混凝土肋凸,混凝土肋凸内在靠近保温层的部位放置有抗形变件,保温层一侧设置有钢筋混凝土现浇单元。
作为本发明进一步的方案:所述混凝土预制构造层由贴近保温层的一层轻骨料混凝土层及外侧的细石混凝土层两层组成。
作为本发明再进一步的方案:所述混凝土预制构造层由单层混凝土层构成。
作为本发明再进一步的方案:所述抗形变件为抗弯钢筋,所述抗弯钢筋的直径为3mm-12mm。
作为本发明再进一步的方案:所述抗形变件为薄壁型钢,薄壁型钢的壁厚为0.1mm-2.0mm。
作为本发明再进一步的方案:所述混凝土预制构造层内包含有钢筋网,第一钢筋网与穿过保温层的斜插腹筋及保温层另一侧的第二钢筋网焊接成空间网架,钢筋焊接网架板由带有凹槽的保温板、第一钢筋网、第二钢筋网和斜插腹筋焊接组合。
作为本发明再进一步的方案:所述轻骨料混凝土层的厚度为10mm-40mm,材质为陶粒混凝土、聚苯颗粒混凝土、珍珠岩混凝土等密度小于1500㎏/m³的轻质混凝土。
作为本发明再进一步的方案:所述混凝土肋凸嵌入保温层的深度为10mm-150mm,宽度为50mm-200mm;其水平间距为600mm-2000mm,竖向间距为1500-4500mm;所述混凝土肋凸的截面形状为矩形、梯形、半圆形或三角形。
作为本发明再进一步的方案:所述保温层的厚度为80mm-300mm,所述钢筋混凝土现浇单元的厚度为50mm-350mm,所述混凝土预制构造层上可设置有阵列式分布的穿墙螺栓孔或穿墙螺栓套管。
作为本发明再进一步的方案:施工工艺步骤如下:
S1:将带有凹槽的保温板、第一钢筋网、第二钢筋网和斜插腹筋焊接组合成钢筋焊接网架板;
S2:在保温板的凹槽内放置抗弯钢筋或薄壁型钢;
S3:浇筑预制构造层的混凝土层或先后浇筑轻骨料混凝土及细石混凝土形成预制单元(4);

S5:将预制单元安装到钢筋混凝土现浇单元的一侧并支设另一侧模板;
S6:浇筑钢筋混凝土现浇单元的混凝土;
S7:拆除钢筋混凝土现浇单元的一侧模板。
与现有技术相比,本发明的有益效果是:
1、双面层做法,既减轻构件自重、提高保温性能,又保证了构件的耐久性。
2、混凝土肋凸能够增加构造层的平面外刚度,保证预制单元在吊装过程中不发生折断。
3、抗弯钢筋或薄壁型钢能够提高混凝土肋凸的抗弯性能。
