相比傳統的石膏材料而言,grc作為一種新型的輕型材料在制造和安裝環節得到了大幅度的技術提升。但是即使如此,在grc構件施工期間有性以及要點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構件施工期間性
Safety during GRC component construction
人生:由于grc構件安裝位置處于室外屬于高空作業,需安裝固定的腳手架和其它保護措施,如未進行保護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.
構件質量:GRC構件是一種以耐堿玻璃纖維為增強材料、水泥砂漿為基體材料的纖維混凝土復合材料,GRC構件的體積密度約為1.8-1.9,8mm厚標準GRC板重量僅為15kg,抗壓強度超過40Mpa,抗彎強度超過34Mpa,大大超過國際標準要求。
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.
構件安裝性:固定件總是位于潮濕環境,大多數鐵合金在這種條件下都會腐蝕,這不僅在建筑材料上形成難看的銹斑,而且對結構造成損害。銹蝕的低碳鋼將會分層并膨脹超過原始厚度的4倍,這種膨脹對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構件施工期間關注要點
Key points for attention during GRC component construction
1、水泥基外墻保溫grc構件應使用抗裂砂漿。此外,重量比應控制在干粉:4和水:5的比例,以便完全攪拌以達到均勻,這個用起來很簡單。
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、
濟南GRC構件的結構寬度在1.10m1.20m范圍內,將攪拌好的保護砂漿自下而上均勻地鋪在grc裝飾構件上,保持在板面的保護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、在防護砂漿仍有良好和易性的時間范圍內,及時將玻璃纖維網布推入防護砂漿中,使網格擠出的防護砂漿平整。玻璃纖維網布應完全包裹在保護砂漿中,一方面玻纖網布應盡量貼近防護砂漿表面。另一方面玻璃纖維網布不應暴露在保護面層的表面。
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.
