Steel the member tube ball node plus liner, each weld expansion should be 1.5-3.5mm, without the liner, the each welds expansion should 1.0m2.mm, caulking steel nodes, each node in the amount of expansion should 2.0m3.Omm .. Steel Ruler sure unanimous Proofing and contemplate measure change negative.
Assembled or pre-assembled the assembly unit should operate on the in chronological size like, do not grasp the size chosen .. unit construction deflection happens in the steel structure folded normal there should be remaining just bracket bracket mounted on the screw steel engineering k to mobilize the steel structure deflection. basis for the steel structure type, size, and practice conditions, installation operation are appropriate to mobilize, so that the deflection value is less than the design values of deflection Steel Components production grid steel structure construction process
The steel structure is damaged, we want instant instant solution, steel grid introduced steel structure damaged main factors: a change in the steel structure carrying capacity by load changes, extended service, rules and regulations; 2) components due accident deformation, distortion, disability, depression, resulting in the member section weaken rod warp connect cracking on; 3) caused by the temperature difference between the role of the member or connection deformation, cracking and warping; 4) due to chemical substances erosion corrosion and electrochemical corrosion of the steel structure weakened member section; 5) steel engineering violations include mistakes in the design, production, construction and service midterm use and operation.
