Description
Technical field
The utility model relates to a kind of big steel column, specifically is a kind of two huge post of inferior font.
Background technology
Center, Shanghai mansion basement structure engineering is divided into main building basement and podium basement part.Wherein the groined type framework is formed by 8 huge posts and 4 corner posts in main building basement engineering periphery, the centre is each shear wall of 30 meters of length and width that steel column and steel wallboard are formed, be made up of wallboard post and clad steel wallboard between huge post and the shear wall, steel is connected into a stable whole between each member.
This engineering design novelty, peculiarly shaped, complex structure, particularly each important node intractability are quite big; Through comprehensive study, analyze the form of structure of this engineering, its main difficult point, characteristics are as follows.
(1) engineering use steel plate thickness is big, strength grade is high, and the steel plate that the basement steel column uses is mainly based on 30mm, 50mm, 55mm, and column base plate thickness then reaches 160mm.Steel grade based on the Q345GJC level, the part is the Q390GJC level in addition, the thick intensity height of steel plate thickness.
(2) complex structure, welding residual stress is big, is out of shape also greatly, and this engineering uses steel to be slab, ultra-thick plate, and it is big to fill wlding deposited metal amount during welding, and weld interval is long, heat input total amount height, so structure post-weld stress and distortion are greatly; Member when welding weld seam constraint (restraint) degree height, welding residual stress are big; This engineering structures complexity in addition, each monomer structure all belongs to " compound " member, and the welding stress direction is inconsistent, and longitudinal and transverse, upper and lower graded crossing interacts and very easily causes the comprehensive distortion of member.
(3) possibility occurrence of bead crack is big; Constraint (restraint) degree was big when this engineering was welded owing to thickness of slab, and the node complexity, and welding residual stress is big, and weld seam single face welding deposited metal amount is big, and the welding activity duration is long, complex process.So in welding welding process, careless slightly easy generation fire check and cold crack.
(4) lamellar tearing tendentiousness is big; Confirm that from soldering theory and welding practice the lamellar tearing defective is the easiest to be created on " cross corner connection and the corner connection of T shape " joint of steel plate thickness direction.This type of joint is used more in this engineering, adds other factors, and this lamellar tearing tendentiousness will increase.
(5) a large amount of high-strength bolt hole precision control is difficult; Wallboard connector welding deformation on the huge post is big, and physical dimension is difficult to control.
In sum, how to overcome the making that above-mentioned difficulties is finished center, Shanghai mansion basement steel work, the most important thing is design, produce a kind of rational huge post.
