Q:What documents do steel installers need to have?
Ask forFor nondestructive testing, liquid penetrant testing, the overall structure, verticality and levelness of packaging: packaging materials, packaging storage methods: the temperature and the humidity of the environment, transport, loading and unloading car placed in containers, display, etc..
Q:What does steel structure "Zhongshan wall post" mean?
The utility model is provided with a reinforced concrete structural column resisting the horizontal wind load in the gable of both ends of the brick concrete structure, and is simply called a wind resistant column. A reinforced concrete beam that connects the wind column in the horizontal direction and acts as an integral reinforcement is referred to as a wind resisting beam. Generally used for high-rise, large internal space, less walls of brick concrete structure housing, such as industrial plants, large warehouses and so on.
Q:Definition of large steel structures
Steel structure is mainly made of steel material, and it is one of the main types of building structure. The structure is mainly composed of steel beams and steel plates, such as steel beams, steel columns, steel trusses and so on. Each component or component is usually connected with welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise and other fields.
Q:What is the edge of the steel structure?
Water is a kind of waterproof technology in construction, popular said is actually in the wall and the roof, is at the intersection of waterproofing in all need waterproof treatment that is the facade, with waterproof material to wrap the corner. And different apron
Q:In the steel structure, should be the first high-strength bolts after the end of the welding, or first screw, then welding after the end of the screw?
Check the batch, that in the former, in the latter does not matter. The key is that the data must be complete. It depends on how the overall project is structured
Q:In the installation of steel structure, insulation foil should be placed in the side wall or side wall? Why?
The reasons are as follows: first, the sound insulation property is good.Two, fire performance is stronger.Three, in order to facilitate installation.
Q:How can the steel structure be laid with flame retardant PVC pipe?
The first group through the PVC tube and the PVC tube, steel wire hanging up this way in the fire and security are also relatively time-saving province cost way.
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.
Q:What does "HW350x350" mean in steel structures?
HW350X350 is a model of hot-rolled wide flange H steel. The standard method is "HW350X350""HW350X350 has two specifications, one is HW350X350X12X19 (high X, wide X, web thick X flange thickness), and one is very use specifications, used very few, the cross section is HW344X348X10X16
