As a  Railway Fastening System Supplier , share with you. The tensile capacity of the anchor bolt is the tensile capacity of the round steel itself, and the size is equal to the cross-sectional area times the design value of the tensile strength (140MPa) is the allowable tensile bearing capacity during design.  Rail Anchor Bolt  generally uses Q235 steel, which is round. I haven't seen the use of threads at present, but it's okay if it is required by force. Rebar (Q345) has high strength, and it is not easy to make a nut screw. Rail Anchor Bolt For light round anchor bolts, the burial depth is generally 25 times its diameter, and then make a 90-degree hook about 120mm long. If the bolt diameter is very large (such as 45mm) and the burial depth is too deep, you can weld the square plate at the end of the bolt, that is, make a big head (but there are certain requirements). The burial depth and the hook are to ensure the friction between the bolt and the foundation, s...

As a  Rail Joint Plate Manufacturer , share with you. In fact,  Rail Joint Plate , also known as fish tail plate, is a railway accessory and an important part of railway turnouts. If there is a problem with the railway splint, it will inevitably affect the driving safety of railway switches. The road plywood must be regularly inspected and maintained. If the road plywood is damaged during inspection, it needs to be repaired or replaced with a new road plywood. In use, the difference between the track length and the weight of four holes and six holes. Because different tracks have certain requirements for the quality of road plywood, the difference between the two holes and the weight is also the difference between the two holes. Railroad tracks are the roads of trains. Railroad tracks are connected by different railway components, and the components connecting the rails are particularly important. Rail Joint Plate Rail Joint Plate is a very important part of railway acc...

Anchor Bolt  is a casting used on the railway, generally made of cast steel. For this type of casting, in addition to strict technical index testing, the material of the equipment should be processed. The castings such as anchor bolts provided by  Railway Fastening System Supplier  have been used in the field environment for a long time, and are eroded by the humid environment. If the maintenance work of castings such as anchor bolts is not done well, it will lead to corrosion of castings. See how Anchor Bolt and other castings should prevent rust. Anchor Bolt Surface treatment method: 1. Surface cleaning: Cleaning must select the appropriate method according to the nature of the surface of the anti-rust object and the conditions at that time. Commonly used solvent cleaning method, chemical treatment cleaning method and mechanical cleaning method. 2. After the surface is dried and cleaned, it can be blown dry with filtered dry compressed air, or dried with a ...

As a  Track Bolt China Exporter , share with you. Spiral spikes are a kind of railway spikes and one of many railway accessories, which play a role in fastening the entire railway track. The importance of spiral spikes is undeniable. Therefore, during daily inspection and maintenance, special attention should be paid to spiral spikes. What are the regulations for anchoring spiral spikes? On the one hand, it is necessary to ensure that the quality of the spiral spike is qualified, on the other hand, it is necessary to correctly install the anchor spiral spike. So, what standards should be met when anchoring spiral spikes? The following will summarize and introduce this problem. Bridge Bolt 1. Spiral spikes are anchored with sulfur cement mortar. The sulfur cement mortar formula and preparation process shall comply with the relevant provisions of the railway track construction and acceptance specifications. 2. Before anchoring, the debris in the reserved holes of the sle...
