Insulation nails are engineering plastic expansion nails used to fix insulation boards to walls. They serve as anchor fasteners for external wall insulation and are widely used in architectural decoration and the anchoring of insulated wall structures. Composed of galvanized screws, nylon expansion tubes, and fixed circular plates, they come in various sizes based on the thickness of the insulation layer. They are extensively used in architectural decoration and the anchoring of insulated wall structures. They feature aging resistance, temperature shock resistance, corrosion resistance, and excellent thermal insulation. They have high load-bearing capacity, good compressive and tensile properties, and are resistant to deformation, moisture, shock absorption, and offer excellent thermal insulation. Installation is simple and does not require special tools. The galvanized screws effectively address corrosion issues and offer excellent durability. The low thermal conductivity of nylon material prevents cold bridges in winter, providing high energy efficiency. They are generally divided into solid wall insulation nails, hollow brick insulation nails, wire mesh insulation nails, and large formwork integrated types. Main sizes: solid: 8×62, 8×82, 8×102, 8×122, 8×142; split: 10×162, 10×182, 10×202, 10×252, 10×302, 10×352, 10×402, 10×452, 10×502, 10×552, 10×602. Performance parameters: in accordance with the JG/T366-2012 standard.
Tapping Anchor Bolt: An anchor bolt that applies expansion force by tapping the expansion joint or expansion sleeve to compress the bore wall.
Requirements:
The nominal diameter of the disc anchor bolt should not be less than 60mm with a tolerance of 1.0mm. The nominal diameter of the expansion sleeve should not be less than 8mm with a tolerance of ±0.5mm.
2. Standard tensile capacity of anchor bolt: Fk ≥ 0.60
3. Anchor Bolt Plate Tension Standard Value: Standard Pull-Out Force of Plate Frk ≥ 0.50; Product Types: Separate Insulation Nails and Integrated Insulation Nails
Thermal insulation nails on the market are mostly integrated, making them easy to use.
There are numerous suppliers that meet this standard, including well-known brands like those north of the Yangtze River; German Hiwin, Foster, Tianjin Owens, Mayline, Snapper, as well as Beijing BoruiTe, Wardraycon, and Shijiazhuang SanQing Precision.
Arrangement of exterior wall thermal insulation nails. Installation quantity of anchor fasteners for extruded polystyrene (XPS) external wall thermal insulation system: 6 nails/㎡ for 1-10 floors, 7 nails/㎡ for 11-20 floors, and 9 nails/㎡ for 21-26 floors. Any single panel larger than 0.1㎡ must have additional anchor fasteners, the quantity depending on the shape and site conditions; around the corners, under eaves, and at the edges of holes, the density of anchor fasteners should be increased, with a distance not exceeding 300mm and not less than 60mm from the edge of the base layer.
