The GRC component making and construction technical requirements
1, in meet the JC/T940-2004 "glass fiber reinforced cement (GRC) decoration products, specifications and the requirements of the country, the industry, GRC continental decoration should be according to the technical requirements, the appended drawings of components and design drawings and installation, as a result of GRC EPS production and installation of the production and installation quality problem and influence caused by the project acceptance and use of all losses shall be borne by party b.
(1) material
Raw material quality should be accord with JG714-1996 respectively,, JGJ63 JGJ52-1992-1992.<
GRC components used within 6 bar (using without cold drawn level 1 reinforced) and pre plate (flat), the material should be in line with the GB/T701-1997 respectively and GB704-1998.
Steel, steel embedded parts should be the factory quality certificate and test report accordingly, and strictly according to the steel grade, specification piled up, not confused, rust protection and pollution at the same time.
Glass fiber cloth with 04 grid cloth, the material conforms to the standard JC/T841-1999.
2 GRC components appearance quality shall meet the following rules in table 1.
Should look realistic, smooth lines, GRC sculpture reliefs, decorative pattern should be clear, smooth lines, complete artistic taste.
Table 1
GRC component making and construction of other requirements:
1, GRC and EPS production and the progress of the installation must meet the total package of the overall construction schedule.
2, a main structural component, GRC installation will obey all GRC components used when installing anchor pieces for anchoring, anchoring a reliable connection with the original subject, at the same time the process related fees including in the total price, installation requires the rear and built-in design must be combined with GRC concrete components, standard, specification, reasonable, safe and strong, and the structure of the original fittings must be meet the requirements of gb standard parts (such as bolts, chemical bolts, etc.).
4, provides the GRC and the Angle between the GRC components, linear connection, GRC components connected to the main body structure node, and elaborate on production and installation of quality assurance measures. GRC components must join point welding is firm, each contact must be double-sided welding, after welding must use red lead antirust processing, and then use the same GRC cement mortar seams material, and handle other crack resistance must be conducted, to ensure that no cracks.
5, GRC components must meet the environmental requirements prescribed by the state.
6, all production process using the release agent must use GRC components country to promote environmentally friendly water-based release agent, surface treatment to ensure that the components of possible conditions.
