How much do you know about Anchor Bolt?

    Anchor Bolt is generally made of Q235 steel, made of round rebar, and many people should be familiar with it. For deep-buried diameters of 25mm 120mm hooks, if you know that bolt-welded square plates are a good If the finished product is used, then the hook will guarantee the basic friction of the bolt. What kind of characteristics do you have? Let's take a look today!
Anchor Bolt
　　First, the anchor bolt
　  Alias stiffening anchor bolt, welding anchor bolt, foot bolt, foot screw, foot wire and so on. It is specially designed for burying in concrete foundations and is used for fixing various machines. It is also used in the Railway Fastening System for the base of the equipment. The 7-word anchor bolt is the more common one in the anchor bolt. It is generally made of Q235 steel. It is made of Q345B or 16Mn with high strength. It is also processed with 40Cr material with 8.8 grade strength, and occasionally with secondary or tertiary rebar. The anchor bolt has different forms of wool, thick rod and thin rod. The wool material, that is, the raw material steel, is not directly modified, and is directly processed from round steel or wire; the thick rod or the A-type, thin rod or B-type is processed from the steel to the corresponding required rod diameter. The welded anchor bolt is made by welding a stiffened iron plate with a single head bolt. Its resistance to drawing is strong. According to the different conditions used, it can reach 3.6, 4.8, 6.8, 8.8 and so on. The tensile strength of the 3.6 grade 7 anchor bolt is the tensile strength of the steel itself. The anchor bolt of Q345B or 16Mn raw material directly processed has a tensile strength of 5.8. The tensile strength of 4.8, 5.8, 6.8 and 8.8 refers to the mechanical properties specified in GB/T3098.1.
　　Second, the installation method
      1. One-time embedding method: When pouring concrete, embed the anchor bolt. When the tower is controlled by overturning, the anchor bolt should adopt a one-time embedding method.
　　2. Reserved hole method: the equipment is in place, the hole is cleaned, the anchor bolt is placed in the hole, and the equipment is positioned and corrected, and then the non-shrinking fine stone concrete higher than the original foundation is used for watering, and the tamping is compact. The distance from the anchor bolt center to the base edge of the buried one shall not be less than 2d (d is the diameter of the anchor bolt), and shall not be less than 15mm (not less than 10mm when d≤20), not less than half of the width of the anchor plate plus 50mm When the above requirements are not met, appropriate measures shall be taken to strengthen them. The diameter of the anchor bolt for the structure should not be less than 20mm. When subjected to earthquakes, double nuts should be used, or other measures to prevent loosening should be used, but the anchor bolt should be anchored for 5 days longer than the non-seismic anchor length.
　　Our company also has Rail Clamp, welcome to come to consult.

Tension Clamp Is Important

图片
With the increase of the axle load of the railway locomotive and the improvement of the running speed of the train, as well as the development of the urban rail transit and the subway, the Tension Clamp  is also becoming a key link in the continuous development of the track structure, which is concerned by all the countries. In the general line, the need is about buckle pressure, good elastic spring, to meet the needs of heavy-duty, high-speed lines, while in the viaduct track seamless circuit, in order to reduce the interaction between the rail and the bridge, we have to ensure the elasticity that is enough, if the train goes through, the loss of undercover cushion due to compression caused by the buckle pressure is small, and fasteners of  Railway Fastening System  do not loose. Although it is a small public work device, but it is an important part of the track, because of its large demand, about 7000 per kilometer, its reliability is directly related to the safety...

Pay Attention to Rail Plate Base Pad

图片
As an indispensable part of the railway, the  Rail Plate Base Pad  plays an important role on the railway. If it falls off, which will influence the whole  Railway Fastening System  deeply. In the high-speed railway subgrade, the separation of the slab Rail Plate Base Pad will reduce the track strength. This situation means the stiffness and service life of the track will be reduced directly. It causes the rail plate base pad to crack and disconnects from the lug time. The pressure of the top surface of subgrade increases with the length of abscission. Meanwhile, the trend of increasing is becoming more and more obvious.

Do You Know Heavy Haul Rail?

图片
The first International Heavy Haul Congress in 1978 was held in Perth, Australia. Since the establishment of the International Association of Heavy Haul Transport in 1985, the definition of heavy railroads has evolved with heavy loads and advancing with the time. In 2005, the International Association of Heavy Load Associations proposed a new heavy haul railway standard that required to meet at least two of the following three conditions: 1.train traction quality is not less than 8000t 2.vehicle axle in the vehicle reach or exceed 27t 3.The length of the line is not less than 150 km, the annual freight volume is not less than 40 million tons. We support several types of  Rail Fastening System  to meet the different rail's requirements.
