The DX direct fixing system includes high-strength bolts, special gunpowder and a special nail gun. The principle of DX direct fixing mainly includes high-strength steel nails driven by gunpowder and passing through steel and concrete at high speed. When the bolts penetrate into steel and concrete, they generate great heat, and the temperature can reach 9000C, resulting in a welding effect between the steel nails and the steel and concrete. Before the bolts work, their strength and bending strength need to be tested, which requires a bolt welding specimen bending detection test device.
