相比傳統(tǒng)的石膏材料而言，grc作為一種新型的輕型材料在制造和安裝環(huán)節(jié)得到了大幅度的技術(shù)提升。但是即使如此，在grc構(gòu)件施工期間有性以及要點(diǎn)還是不能夠被忽視的。

Compared with traditional gypsum materials, GRC, as a new light-weight material, has been greatly improved in manufacturing and installation. But even so, the safety and key points during GRC component construction cannot be ignored.

grc構(gòu)件施工期間性

Safety during GRC component construction

人生：由于grc構(gòu)件安裝位置處于室外屬于高空作業(yè)，需安裝固定的腳手架和其它保護(hù)措施，如未進(jìn)行保護(hù)措施易造成高空墜亡。

Life safety: since GRC components are installed outdoors and belong to high-altitude operation, fixed scaffolds and other protective measures need to be installed. If protective measures are not taken, it is easy to fall from high altitude.

構(gòu)件質(zhì)量：GRC構(gòu)件是一種以耐堿玻璃纖維為增強(qiáng)材料、水泥砂漿為基體材料的纖維混凝土復(fù)合材料，GRC構(gòu)件的體積密度約為1.8-1.9,8mm厚標(biāo)準(zhǔn)GRC板重量?jī)H為15kg，抗壓強(qiáng)度超過40Mpa，抗彎強(qiáng)度超過34Mpa，大大超過國(guó)際標(biāo)準(zhǔn)要求。

Component quality: GRC component is a kind of fiber concrete composite material with alkali resistant glass fiber as reinforcement and cement mortar as matrix material. The volume density of GRC component is about 1.8-1.9, and the weight of 8mm thick standard GRC plate is only 15kg. The compressive strength exceeds 40MPa and the flexural strength exceeds 34mpa, which greatly exceeds the requirements of international standards.

構(gòu)件安裝性：固定件總是位于潮濕環(huán)境，大多數(shù)鐵合金在這種條件下都會(huì)腐蝕，這不僅在建筑材料上形成難看的銹斑，而且對(duì)結(jié)構(gòu)造成損害。銹蝕的低碳鋼將會(huì)分層并膨脹超過原始厚度的4倍，這種膨脹對(duì)GRC板有明顯損害。

Safety of component installation: the fixed parts are always located in a humid environment, and most ferroalloys will corrode under this condition, which will not only form ugly rust spots on the building materials, but also cause damage to the structure. The corroded mild steel will be stratified and expanded more than 4 times the original thickness, which will obviously damage the GRC Plate.

grc構(gòu)件施工期間關(guān)注要點(diǎn)

Key points for attention during GRC component construction

1、水泥基外墻保溫grc構(gòu)件應(yīng)使用抗裂砂漿。此外，重量比應(yīng)控制在干粉：4和水：5的比例，以便完全攪拌以達(dá)到均勻，這個(gè)用起來(lái)很簡(jiǎn)單。

1. Anti crack mortar shall be used for GRC components of cement-based exterior wall insulation. In addition, the weight ratio should be controlled at the ratio of dry powder: 4 and water: 5, so that it can be completely stirred to achieve uniformity, which is very simple to use.

2、濟(jì)南GRC構(gòu)件的結(jié)構(gòu)寬度在1.10m1.20m范圍內(nèi)，將攪拌好的保護(hù)砂漿自下而上均勻地鋪在grc裝飾構(gòu)件上，保持在板面的保護(hù)砂漿的平均厚度小于3毫米。

2. The structural width of Jinan GRC members is within the range of 1.10M to 1.20m. The mixed protective mortar is evenly laid on GRC decorative members from bottom to top, and the average thickness of the protective mortar on the plate surface is kept less than 3mm.

3、在防護(hù)砂漿仍有良好和易性的時(shí)間范圍內(nèi)，及時(shí)將玻璃纖維網(wǎng)布推入防護(hù)砂漿中，使網(wǎng)格擠出的防護(hù)砂漿平整。玻璃纖維網(wǎng)布應(yīng)完全包裹在保護(hù)砂漿中，一方面玻纖網(wǎng)布應(yīng)盡量貼近防護(hù)砂漿表面。另一方面玻璃纖維網(wǎng)布不應(yīng)暴露在保護(hù)面層的表面。

3. Within the time range when the protective mortar still has good workability, push the glass fiber mesh into the protective mortar in time to make the protective mortar extruded by the grid smooth. The glass fiber mesh should be completely wrapped in the protective mortar. On the one hand, the glass fiber mesh should be as close to the surface of the protective mortar as possible. On the other hand, the glass fiber mesh should not be exposed to the surface of the protective surface.
