Nylon column shoesProfile
Nylon column shoes is from the support surface, the support ribs, grooves mosaic composed of static light column shoes column caps, its overall antistatic agent can be modified using the MC nylon casting or deep or use antistatic antistatic film coated on the column shoes column cap outer surface,mechanical performance and antistatic performance indicators to achieve the requirements for mining, especially for coal mining face, and friction hydraulic prop pillar. Application scope Nylon column shoes for coal and other mines, tunnels and other monomers used in face support pillar column shoes, the product utility model relates mine support products for soft bottom stopes, especially special soft floor conditions single pillar column shoes. Parameter Insole with a nylon column bottom, bottom to increase bearing area, improve supporting strength. The column shoes by rock mechanics and strata control center experimental test, the compressive capacity of 535kN ~ 560kN, shear capacity of 562kN. Its carrying capacity is the single pillar working resistance 1.8 times higher than the industry standard. The column shoes d 280 mm, the total thickness of 55mm, the middle groove diameter 125mm, depth 15mm, the bottom thickness 40mm, fluted columns along the circumference 8 Li radioactive strengthen tendons, Its tilt vertical height 30mm. In the column shoes studs drill a gap of 10mm diameter holes to tether chain use.
