Now many buildings will use the GRC component, but many manufacturers are to provide custom, did not contain the construction, or part of the need for their own construction, this time the installation of GRC component will encounter the problem of dealing with joints, then the external GRC component Who deal with the following bar care grc component manufacturers to give you under the following description:
GRC is a kind of composite material which adopts anti-alkali glass fiber, mixed high-grade high-quality special cement and a variety of lightweight materials and embedded metal parts, specially crafted. Is widely used in construction projects in the European architectural lines, high strength, light, cheap is its greatest feature.
External wall GRC component joints are generally handled by GRC installation manufacturers. Can also be negotiated by the next process group processing.
External wall GRC component Sealing treatment method:
1, installation, fixation method
A, expansion screw anchorage method: the GRC board according to the installation requirements on the product set aside screw hole (retractable), screw hole spacing level greater than 400mm, the vertical direction is not greater than 500 mm, and then use the expansion screw directly anchored in the wall Column) surface.
B, welding method: in the wall (column) surface by GRC component installation requirements to set the embedded iron, and then welding. Method: The steel plate embedded in the inner wall of the GRC is welded directly or with a connecting rod. In order to ensure the quality of the installation, the surface of the wall (column) substrate must be properly cleaned before the GRC component is installed. The embedded parts are required to be 15 mm inside the exterior wall to prevent spilled water from overflowing.
2, seam processing
A, GRC component installation, the seam width control in about 5 mm.
B, GRC component between the joints using ordinary cement, fine sand and acid-based adhesive even after mixing even three times the seams.
C, GRC component and wall joints, the use of water emulsion white building sealant.
D, GRC component and aluminum alloy surface of the joints, the use of neutral white silica gel.
This is where the GRC component joints are shared.
