Project Reference:

The new railway section of bullet train is the inspection and repair base for north China and
the inspection and repair center for the north section of Beijing to Shanghai high-speed
railway. The total area is 183,330 square meters. The steel structure adopt arch steel truss
with maximum span 36 meters.

Q:What exactly does the steel structure contain?
For the steel structure production information, usually steel structure, processing factory in the component when the factory has been prepared and completed, with the piece into the field. The installation materials are compiled and arranged on the spot.
Q:In architectural design, what are the sectional sizes of square columns and columns in various structural forms (such as concrete, steel structures, wood structures)?
Wood structure only exists in the lower layer of ancient architecture, round, diameter, as a result of growth restrictions, as far as possible to choose the more robust. Rare, square cross section.
Q:What does "HJ-1" mean in steel structures?
In steel structure, HJ-1 is truss number 1.
Q:What kind of material test is necessary for steel structure engineering?
The test of high strength bolt connection must be done, and the anchor bolt needs to be made of raw material.
Q:What effect does the welding slag not have on the steel structure or the reinforced concrete structure?
Check the pressure leakage test of the pipeline. Water test, if there is a leak point, because the welding slag cover, the exudation of water may not be out of the leak point, is not conducive to check the location of leakage point.
Q:In the installation of steel structure, insulation foil should be placed in the side wall or side wall? Why?
This is not strictly required, generally in the installation of steel structure workshop enclosure plate, insulation foil should be in the inner side of the wall.
Q:How much is steel per square meter of steel foundation?
All types of foundations are not exactly the same. It is recommended that you calculate the total amount of reinforcement, and then divide the area to get the square meter content. This is more accurate.
Q:How to determine the thickness of anticorrosive paint for steel structure?
When the design does not require the coating thickness, the total thickness of the coating should be 150 m, and the room shall be 125 m, the allowable deviation is -25 mu m. The allowable deviation of the dry paint film thickness per time is -5 mu m." Check quantity: according to the number of components, check 10%, and similar components should not be less than 3 pieces.
Q:Is the metal structure the same as the steel structure?
Steel structure is one of the metal structures. Steel structures refer to ferrous or carbon steel structures. The metal structure will be: non-ferrous metal structure (stainless steel), aluminum alloy structure and so on.
Q:What can be painted on the surface of steel structure to prevent rust and corrosion?
Bridge steel structure (long acting type): primer is epoxy zinc rich primer, intermediate paint is epoxy micaceous iron intermediate paint, finish is polysiloxane finish coat
