與混凝土產(chǎn)品相比，GRC產(chǎn)品構(gòu)件薄、重量輕、強(qiáng)度高、韌性高、抗沖擊性好、纖維分布均勻、開(kāi)裂性好、制作簡(jiǎn)單、造型豐富、用途廣泛。小編提醒您，
山東GRC構(gòu)件外墻裝飾面有四點(diǎn)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!
一點(diǎn)：
one o'clock:
GRC產(chǎn)品之間安裝后產(chǎn)生的裂縫大多發(fā)生在垂直和水平長(zhǎng)度較大的GRC構(gòu)件接頭之間，導(dǎo)致線條分割明顯，嚴(yán)重影響外飾效果。GRC產(chǎn)品線大多在外裝飾中制成1.5~3米/根，并通過(guò)多個(gè)連接安裝在一起來(lái)勾勒外墻效果。
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，安裝時(shí)受力不均，受自重影響，相鄰接頭之間產(chǎn)生裂縫；另一方面，線條安裝時(shí)由多個(gè)連接，接頭在施工過(guò)程中用1:2水泥砂漿填充，熱膨脹系數(shù)不同于GRC水泥產(chǎn)品。造成裂縫；安裝GRC構(gòu)件時(shí)，尤其是水平線沒(méi)有留下伸縮縫。當(dāng)溫度變化時(shí)，接頭被拉開(kāi)或擠出，導(dǎo)致裂縫。
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.
二點(diǎn):
Two points:
GRC水泥構(gòu)件在埋入鋼框架的位置發(fā)生沿鋼筋方向的銹蝕裂紋GRC構(gòu)件中的埋入鋼框架鋼筋和埋入材料應(yīng)采用鍍鋅鋼筋或不銹鋼條，或采用其他防銹處理，避免銹蝕裂紋的發(fā)生，上的危險(xiǎn)。
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.
三點(diǎn):
Three points:
GRC構(gòu)件的滲水和墻面污染外墻彩色GRC構(gòu)件安裝使用后，特別是水平線下雨天雨水滲出，線上的雨水也沿線流向墻面，線上的灰?guī)У酵鈮γ?。外墻形成污跡，嚴(yán)重污染墻面，影響建筑物外觀。
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.
造成該病的主要原因：
Main causes of the disease:
一是因?yàn)榫€條在安裝過(guò)程中沒(méi)有鑿除舊建筑安裝線條處的墻面粉刷層，或者新建筑是先粉刷后安裝線條，再補(bǔ)縫；
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;
二是由于水平線或柱頂蓋板口沒(méi)有找坡，沒(méi)有做滴水線，導(dǎo)致雨水從線上進(jìn)入線內(nèi)，從線下流出或沿線流向外墻，造成墻面污染。
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.
四點(diǎn)：
four o'clock:
GRC構(gòu)件安裝通病GRC構(gòu)件安裝在外墻時(shí)，一般根據(jù)制造商提供的安裝圖，在外墻面安裝8~10個(gè)普通膨脹螺栓，6個(gè)鋼筋與線埋入鋼筋焊接，或者用膨脹螺栓直接將裝飾凸起、窗頂固定在墻面上。
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線的安裝方法，在施工中一般采用點(diǎn)焊的方法，焊縫長(zhǎng)度達(dá)不到要求，膨脹螺栓打墻后，很容易打到磚縫上，不能起作用，達(dá)不到施工規(guī)范的要求，給GRC構(gòu)件的安裝帶來(lái)了隱患。更多相關(guān)事項(xiàng)就來(lái)我們網(wǎng)站

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.nyqaac.com Consult!
