There is an optimal condition for driving pins into the substrate: for concrete, the nails must be securely fixed with maximum pull-out force while minimizing damage to the substrate. This requires controlling the diameter of the nail and ensuring that the insertion depth reaches the “optimal“value of 22-32mm. For steel substrates with a thickness of 6-12mm, the nail tip should penetrate the back of the substrate for best results. For brickwork, the “optimal” insertion depth is 30-50mm. The “optimal” insertion depth and conditions for other substrates can be determined by referring to the above data or through testing.
The bond between the nail and the substrate is achieved primarily through pressure exerted by the substrate on the surface of the nail. The strength of this bond is therefore limited by the substrate and condition, the size and shape of the nail shank, and the depth of insertion. Therefore, nail gun fastening is suitable for general light to medium fastening requirements and can only withstand normal static loads and some limited dynamic loads, but not impact or vibration loads.
A series of measures have been taken from the design, manufacturing to acceptance of nails, power loads and nail guns to ensure safety during use.
Nailer fastening technology is an advanced modern fastening technology. Compared with traditional pre-buried fixation, drilling and pouring, bolt connection, welding and other methods, it has many advantages: self-powered, eliminating the cumbersome wiring of wires, air ducts, etc., convenient on-site and high-altitude operations; quick operation and short construction period; greatly reduced labor intensity; reliable and safe, and can even solve some construction problems that were difficult to solve before; saving costs and reducing construction costs.
