20MnTiB steel is the most widely used high-strength bolt material for steel structure bridges in China, and its performance is of great significance to the safe operation of bridges. China And Thailand Reach Agreement on High Speed Rail LinkThe fast clip fastening system has substantial global references on both concrete and steel applications. Fast clip fastening is a threadless fastening, with low maintenance and pre-assembly of the fastening which remains captive on the rail sleepers. Fast clip fastening has been designed as a total system, in which all components are delivered to site pre-assembled on rail sleepers.
Dog spikes and screw spikes are two most common railroad spikes that AGICO manufactures,it is small part used to ensure the safety of railway fastening systems. Both spike functions by the equipped offset head, so as to work as a nail that secure and fasten rails on the rail sleeper. Dog spike was first to be invented in 1832, its named for the Design and optimization of the large span dry-coal-shed (1) The material:The material of steel pipe, sealing plate and cone-shaped connectors all select the Q345B, and design strength is 315N/mm2. High-strength bolt using 40Cr or 20MnTiB. Bolt sphere select 45 steel. (2)The deflection limit value:Considering large deformation will affect the drainage and safety of Experimental and Numerical Analysis on Full High Strength Aug 04, 2018 · Full-scale experimental study and numerical analysis on behaviors and failure mechanisms of full high strength steel extended endplate connections in fire have been carried out and presented in this paper. The experimental behaviors of the connections were compared with the provisions of Eurocode 3. The test results show that the failure modes of the connections in fire are
