Q:What are the accessories in the steel structure?
The maintenance system includes: roof and wall inside and outside pressure plate (a single plate project) and thermal insulation layer, and various accessories, standard parts, gutter drainage wall and roof lighting and window part.
Q:Installation quota, there are tubes, steel structures and general steel structure, how to distinguish between the two?
Installation quota, the pipe structure is hollow, pipe, solid steel, and the two how to distinguish between the problem, that is, hollow and solid division.
Q:What is steel structure steel plate?
Steel structure column spacing of 5~9.0m * 8~15m, secondary beam spacing of 3M, and the floor plate length is 4.97~8.97m, the transportation and installation is difficult, especially with the arc area of vertical lifting floor plate, from top to bottom in the secondary beam is sheathed HAZAMA is difficult, and disturb the normal beam welding process.
Q:What does LL represent in steel structures?
LL means coupling beam.The coupling beam refers to the connection between the wall member and the wall member in the shear wall structure and the frame shear wall structure, and the coupling beam is the beam at both ends connected with the shear wall in the plane
Q:What is the foundation and the main structure of the construction project?
The main structure is based on the foundation, and accepts, bears and delivers all the upper load of the construction project, and maintains the whole structure, stability and safety of the superstructure
Q:What are the connecting forms of steel structures? What are the characteristics of each?
Welding is the heat generated by the arc, the electrode and welding parts of local melting. After cooling into the welding seam, so that the welding piece is connected as a whole. The advantages are: the component in any form can generally direct orange even, does not weaken the component section. The economic materials, simple structure, convenient manufacture, connection stiffness, good sealing performance, can realize automatic operation, high production efficiency. The disadvantage is due to the formation of steel; weld heat affected zone of high temperature welding, resulting in local brittle material. In the process of welding material is not uniform with high temperature and cooling, the structure of the welding residual stress and deformation of the structure bearing capacity, stiffness and performance have certain effect. In addition, due to the rigidity of welded steel structure, local cracks can easily spread to the whole as soon as they occur, especially brittle at low temperatures. Moreover, the plasticity and toughness of the welding are poor, and the defects may be caused by blasting, and the fatigue strength is reduced.
Q:What are the joint forms of steel structures?
Many, like the beam column node, beam and beam joint, diagonal node, combination node, the node you can look at the Atlas Design Institute issued, there is full.
Q:Tall steel columns with studs what effect is there?
Methods: through stud welding welding robot power, column set in stud welding gun, anti arc seat, starting gun, current fuse, ring is generated by arc, short columnar stud with a certain speed the top tight end of base metal melting, cut off the power supply of columnar stud welding fixed to the base metal. This method is also called stud welding.
Q:What is the difference between rigid connection and hinge in steel structure?. Are all high strength bolts connected just now?
The difference between the rigid connection and the hinge is whether the support passes the bending moment. Rigid transfer moment, hinge not transfer moment. Simply supported is hinged, solid support is rigid. High strength bolts are mainly used for shearing, and whether they are connected directly or not.
Q:Which engineering structures are more economical and rational with steel structure?
Heavy industrial buildings, large span structures, high-rise and super high-rise buildings, light steel roofs, mast structures.
