What is the size of fish plate?
Fish Plate/ Joint Bar in Size: 52kg, 60kg, 90R.
How many types of fish plates are there?
In general, railway fish plates can be divided into three types, light rail fish plate, heavy rail fish plate and super heavy rail fish plate. Railway fish plate is a type of rail fastener that connect with the two rail ends.

What is bearing plate in railway?
BEARING PLATES : They are the plates placed in between the flat footed rails and timber sleepers on a track. They serve as chairs for flat footed rails. They are made of cast iron, wrought iron or steel.
Why is it called a fish plate?
In rail terminology, a fishplate, splice bar or joint bar is a metal bar that is bolted to the ends of two rails to join them together in a track. The name is derived from fish, a wooden bar with a curved profile used to strengthen a ship’s mast.
What is a bearing plate?
: a plate placed under one end of a truss beam, girder, or column to distribute the load.
What is a base plate?
: a plate that serves as a base or support.
Why bearings are used in bridges?
A bridge bearing carries the loads or movement in both vertical and horizontal directions from the bridge superstructure and transfers those loads to the bridge piers and abutments. The loads can be live load and dead load in vertical directions, or wind load, earthquake load, etc., in horizontal directions.
What is a steel bearing plate?
A bearing plate takes the reaction of a steel beam and distributes that force over a larger area that is made of a material that is not as strong as steel. A bearing plate is generally a rectangular plate that can described by its dimensions as shown in Figure 8.6.
How do you calculate load bearing capacity of steel plate?
Load carrying capacity is something you can not exactly calculate by just knowing material. So best way to calculate is to put that strip in UNIVERSAL TESTING MACHINE,It works on stress strain curve, you can fixed one end and check its tensile strength by applying load axially.Load carrying capacity is wher.

What is bearing strength of concrete?
The bearing strength of concrete is simply the compressive strength of the concrete and the ratio of the total surface area to the load bearing area (known as bearing ratio).
What is the load bearing capacity of concrete?
Imposed loads varies from approximately 1.5 kN/m2 (153 kg/m2) in domestic buildings to approximately 10 kN/m2 (1053 kg/m2) in heavy industrial areas.
What is the bearing stress?
Bearing stress is the contact pressure between the separate bodies. It differs from compressive stress, as it is an internal stress caused by compressive forces.
What does 4000 PSI concrete mean?
3,000 PSI. 4,000 PSI. The strength of concrete is measured in pounds per square inch (PSI) and is a measurement of the concrete’s ability to carry loads or handle compression. The higher the number, the stronger the concrete.
How many PSI Do I need to clean concrete?
Most electric pressure washers create 1300-1700 pounds per square inch of pressure (PSI) with a water flow of 1.5 gallons per minute (GPM), but experienced contractors recommend between 20 PSI and a flow of at least 2.5 GPM to clean dirty concrete effectively.
What is 6000 psi concrete used for?
For new concrete construction projects, concrete overlays and concrete repairs. Use to construct footings, sidewalks, slabs, steps and patios, setting deck posts, fence posts or poles.
What PSI should concrete slab be?
Typically, reinforced concrete ranging between 3,500 to 4,000 psi is used on footing and slabs on grade; between 3,500 to 5,000 psi on suspended slabs, beams and girders; and walls and columns normally require between 3,000 to 5,000 psi. When non-reinforced concrete is used different strengths will be required.
Do you need rebar for 4 inch slab?
No, you do not need rebar for a 4-inch slab of concrete on grade. A 4-inch-thick slab cast on the ground and in permanent contact with it will float and rebar is not required. Rebar is recommended on concrete measuring 5 – 6 inches thick.
What is the difference between 3000 psi and 4000 psi concrete?
3000 PSI concrete is a standard multipurpose mixture for general use in construction. 4000 PSI concrete is used for heavy traffic pavement, heavy use floor slabs like shops and warehouses, and concrete footings designed to support heavy loads.
