Abstract
本发明涉及一种石材铺筑工程施工方法,特别涉及一种巨型石材铺筑工程预压法,操作步骤如下:通过模拟实验得到压实之后的厚度与虚铺厚度之比,确定砂浆的压缩系数;在基层上虚铺一层干硬性砂浆;用强力压实机械压实虚铺砂浆,并依据压缩系数,按厚度变化控制压实过程;取样实验确认密实度;在压实的砂浆层表面按照规定进行网格划毛;浇洒素水泥浆;落放巨型石材,将铺筑厚度分解为石材厚度和砂浆厚度两个指标进行控制,便于分析和控制施工质量。在石材就位前压实砂浆并检查砂浆密实度,易检查验收、方便快捷实用,不影响工程进度,尤其适用于不便于人工搬移、掀起的巨型石材的铺筑操作程序,能明显有效地保证施工质量。
Description
技术领域
本发明涉及一种石材铺筑工程的施工方法,特别涉及一种巨型石材铺筑工程预压法。
背景技术
在路面、广场等建设项目中铺砌石材地面的传统方法是:在基层上虚铺一层干硬性水泥砂浆,所述干硬性水泥砂浆是通常所说的手握可成团,放手可散落的水泥砂浆,然后放置石材,再以橡皮锤击打,直至砂浆被挤压、石材恰恰沉落到设计规定的地面高度,即地面标高,当标高不能够达到设计要求时,要搬移石材,铲薄或者添补砂浆,清理石材底面,即将被石材底面所粘起的砂浆必须铲除清理干净,然后重新放置石材,再次击打,直至达到设计要求。这样的铺筑方法存在以下缺点:
1.对于大型石材难于实现反复搬起、落放、翻转。
2.对于精加工的石材容易被砂浆等污染。
3.在要求检验砂浆的密实度的时候,必须将最后已经就位的石材掀起,进行砂浆取样,工作复杂、工作效率低,不方便抽检,影响工程进度。
发明内容
本发明的目的在于提供一种便于质量控制、保证施工质量的巨型石材铺筑工程预压法。
本发明通过以下技术方案实现:
本发明的一种巨型石材铺筑工程预压法,其操作步骤如下:
1).通过模拟实验得到压实之后的厚度与虚铺厚度之比,确定砂浆的压缩系数;
2).在基层上虚铺一层干硬性砂浆;
3).用强力压实机械压实虚铺砂浆,并依据压缩系数,按厚度变化控制压实过程;
4).取样做实验,确认密实度;
5).在压实的砂浆层表面按照规定的网格划毛;
6).浇洒素水泥浆;
7).落放巨型石材。
本发明具有如下显著优点:
1).将铺筑石材过程中的铺筑厚度即从基层表面到石材表面的厚度分解为石材厚度和砂浆厚度两个指标进行控制,便于分析和控制施工质量。
2).在石材就位前压实砂浆,并检查砂浆密实度,这比掀起就位后的石材进行砂浆取样,实用方便。
3).以划毛和浇洒素水泥浆保证石材和砂浆层紧密牢固结合。
4).便于检查验收、可方便快捷地抽检,不影响工程进度。
本方法尤其适用于不便于人工搬移、掀起的巨型石材的铺筑操作,能够明显有效地保证施工质量。
具体实施方式:
下面结合具体实施例对本发明作进一步介绍,但不作为对本发明的限定。
一种巨型石材铺筑工程预压法,操作步骤如下:
本实施例是实用于铺筑大小为长2米×宽1米×厚0.3米的巨型石材,首先通过模拟实验得到压实之后的厚度与虚铺厚度之比,根据设计要求确定砂浆的压缩系数,通常是在1:1.3至1:15之间,确定了砂浆的压缩系数之后,进行现场施工,在基层上虚铺一层干硬性砂浆,用强力压实机械如平板振捣器等器械压实虚铺砂浆,并依据压缩系数,按厚度变化控制压实过程;取样做实验,确认密实度;在压实的砂浆层表面按照规定进行网格划毛;所述按照规定是按照规定的划入深度和划线宽度以及最低网格疏密程度划毛表面;浇洒素水泥浆;落放巨型石材。
