GRC构件外墙装饰面有四点要多注意

来源:http://www.aswjc.com/ 发布人:admin 发布时间:2022-10-18

与混凝土产品相比,GRC产品构件薄、重量轻、强度高、韧性高、抗冲击性好、纤维分布均匀、开裂性好、制作简单、造型丰富、用途广泛。小编提醒您,山东GRC构件外墙装饰面有四点要多注意!
Compared with concrete products, GRC products have thin components, light weight, high strength, high toughness, good impact resistance, uniform fiber distribution, good cracking, simple fabrication, rich modeling, and wide applications. Xiao Bian reminds you that there are four points to pay more attention to the exterior wall decorative surface of Shandong GRC component!
一点:
one o'clock:
GRC产品之间安装后产生的裂缝大多发生在垂直和水平长度较大的GRC构件接头之间,导致线条分割明显,严重影响外饰效果。GRC产品线大多在外装饰中制成1.5~3米/根,并通过多个连接安装在一起来勾勒外墙效果。
The cracks between GRC products after installation mostly occur between GRC component joints with large vertical and horizontal lengths, resulting in obvious line segmentation, which seriously affects the exterior decoration effect. GRC product lines are mostly made into 1.5~3m/piece in exterior decoration, and are installed together through multiple connections to outline the exterior wall effect.
一方面自重重,安装时受力不均,受自重影响,相邻接头之间产生裂缝;另一方面,线条安装时由多个连接,接头在施工过程中用1:2水泥砂浆填充,热膨胀系数不同于GRC水泥产品。造成裂缝;安装GRC构件时,尤其是水平线没有留下伸缩缝。当温度变化时,接头被拉开或挤出,导致裂缝。
On the one hand, due to heavy self weight, the force is uneven during installation, and cracks occur between adjacent joints due to the influence of self weight; On the other hand, the lines are connected by multiple connections during installation, and the joints are filled with 1:2 cement mortar during construction. The thermal expansion coefficient is different from that of GRC cement products. Causing cracks; When installing GRC members, especially the horizontal line, there is no expansion joint left. When the temperature changes, the joint is pulled or extruded, causing cracks.
二点:
Two points:
GRC水泥构件在埋入钢框架的位置发生沿钢筋方向的锈蚀裂纹GRC构件中的埋入钢框架钢筋和埋入材料应采用镀锌钢筋或不锈钢条,或采用其他防锈处理,避免锈蚀裂纹的发生,上的危险。
Rust cracks along the direction of reinforcement occur at the position where GRC cement components are embedded in the steel frame. The embedded steel frame reinforcement and embedded materials in GRC components shall be galvanized steel bars or stainless steel bars, or other anti rust treatment shall be used to avoid corrosion cracks and eliminate safety hazards.

三点:
Three points:
GRC构件的渗水和墙面污染外墙彩色GRC构件安装使用后,特别是水平线下雨天雨水渗出,线上的雨水也沿线流向墙面,线上的灰带到外墙面。外墙形成污迹,严重污染墙面,影响建筑物外观。
Water seepage of GRC components and wall pollution After the installation and use of the color GRC components of the exterior wall, especially when it rains on the horizontal line, the rainwater on the line also flows to the wall, and the ash on the line is carried to the exterior wall. Dirt is formed on the exterior wall, which seriously pollutes the wall and affects the appearance of the building.
造成该病的主要原因:
Main causes of the disease:
一是因为线条在安装过程中没有凿除旧建筑安装线条处的墙面粉刷层,或者新建筑是先粉刷后安装线条,再补缝;
First, the wall painting layer at the installation line of the old building was not chiseled out during the installation of the line, or the new building was painted first, then the line was installed, and then the joint was filled;
二是由于水平线或柱顶盖板口没有找坡,没有做滴水线,导致雨水从线上进入线内,从线下流出或沿线流向外墙,造成墙面污染。
Second, because the horizontal line or the opening of the column top cover is not sloped and there is no drip line, the rainwater enters the line from the line, flows out from the line or flows to the exterior wall along the line, causing wall pollution.
四点:
four o'clock:
GRC构件安装通病GRC构件安装在外墙时,一般根据制造商提供的安装图,在外墙面安装8~10个普通膨胀螺栓,6个钢筋与线埋入钢筋焊接,或者用膨胀螺栓直接将装饰凸起、窗顶固定在墙面上。
The common safety problem of GRC component installation When GRC component is installed on the external wall, generally according to the installation drawing provided by the manufacturer, 8~10 ordinary expansion bolts are installed on the external wall, 6 steel bars are welded with the embedded steel bars, or the decorative bulges and window tops are directly fixed on the wall with expansion bolts.
以上PU线的安装方法,在施工中一般采用点焊的方法,焊缝长度达不到要求,膨胀螺栓打墙后,很容易打到砖缝上,不能起作用,达不到施工规范的要求,给GRC构件的安装带来了隐患。更多相关事项就来我们网站http://www.aswjc.com进行咨询吧!
The installation method of the above PU line is generally spot welding during construction. The length of the weld does not meet the requirements. After the expansion bolt hits the wall, it is easy to hit the brick joint, which does not work, and does not meet the requirements of the construction specifications. This has brought hidden dangers to the installation of GRC components. Come to our website for more information http://www.aswjc.com Consult!
