Railway bridge concrete sleeper pillow spike anchor _ _ _ bridge concrete sleeper pillow spike anchor _ Prefabricated Bridge cement joints, mechanical equipment anchor bolt; anchor bolt mechanical equipment; railways, tunnels, water tunnels, coal pier reinforcement, housing earthquake, metallurgy, mining and other underground engineering rock bolts were supporting rapid construction; reinforced concrete structure of old and new building projects led nail anchor, and meet the requirements of welded steel and industrial plants, railways, roads, bridges, water conservancy and hydropower expansion project anchorage reinforcement. Plastic anchor bolts, spikes anchoring agent, Features 1. Anchor plastic hardened, high pullout: Spikes anchor pullout after 4h ≥60KN. 2. wet insulation performance, in line with the railway application standards. 3. Anti-fatigue performance, after six million times fatigue load cycles intact. 4. superfluid, good flow properties so dense spike hole filling. 5. good frost resistance, normally under construction at -50 ℃ negative temperature, negative temperature environment does not affect the strength of the growth of Anchorage. 6. No contraction: no shrinkage after grouting molding, ensure that the installation requires a high accuracy. 7. resistance to heat and acid corrosion excellent for corrosive applications. 8. It does not contain harmful ingredients steel can not rust spike protection. 9. excellent creep resistance:? Can be performed at -80 ° C to + 80 ° C alternately freezing and thawing, the vibration compression harsh physical conditions of long-term use without plastic deformation. Plastic anchor bolts, spikes of Anchorage, Anchor plastic performance parameters ??????? sulfur product performance anchoring agent LD-211 screw spike anchoring agent pullout> 60KN> 90KN wet insulation 1.5MΩ 50MΩ fatigue resistance 2,000,000> 6,000,000 times more than with the effect of construction, masonry kitchen pot racks, brewed, not moving. can be a single person operation, no complicated tools to follow the anchor point moves. Social generate large amounts of toxic gases, smoke for construction workers, plants and animals, causing great harm to the environment does not produce any toxic substances and harmful gases, is green-anchoring agent
