Specific embodiment
Traditional mountain type nut parent size is small, and filament snap ring number is few, and with antiskid button ability is poor, bearing capacity after screw rod installation
It is low.The quantity for increasing mountain type nut parent can only be taken in response to this or increases the size of mountain type nut parent；But increase
Add the quantity of mountain type nut parent to will increase recruitment and materials；Therefore the dimensional directions for increasing mountain type nut parent are ground
The parent of mountain type nut is then changed to 2, every end in research and development by hair, and size amplifies 1.5 times, is carried out after improving processing screw thread precision
Anti-skid test, anti-slip ability have certain promotion；The parent quantity of mountain type nut is changed to 1, every end, size amplification 3 again
Times, mechanics examination experiment is carried out again, and when pulling force reaches 150KN, nut and being engaged for screw rod are complete, and screw rod does not occur obviously to become
Shape meets design and construction requirement.By above-mentioned experimental result, for disadvantage existing for traditional split bolt, to screw rod
The size and number of the parent of screw thread, screw pitch and mountain type nut is transformed, and invents a kind of split bolt bracing means to solve
Certainly the shortcomings that traditional split bolt, construction quality is improved, is accelerated construction progress, propulsion energy-saving consumption reduction reduces engineering totle drilling cost.
