Background
The super high-rise building Guangzhou east tower project has a height of 530 meters, and a planning construction 116 floor comprises 113 floors of the overground part and 3 floors of the underground part, wherein the total steel consumption is 9.4 ten thousand tons, and the super high-rise building is the first high building in the south China. The connected box shear wall structure is applied to the building steel structure industry for the first time, along with the rising of floors, the thickness of a steel plate of the shear wall structure is gradually reduced, the thickness of a wing plate in the connected box shear wall structure is 40mm, the thickness of a web plate is 40mm, and the thickness of a longitudinal narrow partition plate and a transverse partition plate is 16 mm. The combined welding line of the box body is a full penetration welding line.
Because the steel plate has thicker wall thickness, strong rigidity and high requirement on heat input, in the process of combining the integral box shear wall components during the process, the conventional assembly process easily causes the section size, the distortion deformation and the steel plate planeness of the finished component to exceed the standard, does not meet the national standard requirement and even easily causes the component to be scrapped in the procedures of steel plate correction, blanking, groove processing, component assembly, welding and the like.

and a sixth step: assembling a plurality of square-shaped transverse partition plates on the first wing plate and the second wing plate, and welding; temporary supports are additionally arranged on the sides where the partition plates are not installed for constraint;
the seventh step: flatly paving a third wing plate and a fourth wing plate on the square transverse partition plate, wherein the fourth wing plate is assembled and welded with a second longitudinal narrow partition plate, and an internal welding seam is welded;
eighth step: and (4) turning the component down, and welding the butt-joint welding seams between the box bodies in sequence.
In order to ensure the rigidity of the panel and reduce the possibility of deformation possibly occurring in the manufacturing process, the steel plate in the first step is a hot rolling leveling plate, and the thickness of the steel plate is 30-40 mm.
In order to control the heat input amount, reduce the deformation of the steel plate caused by the influence of heat, ensure uniform heat input and reduce the non-uniformity of deformation, the welding is carried out by using a semi-automatic gas shielded welding machine, and in order to reduce the deformation degree of the steel plate to the maximum extent, the main body long weld seam welding in the eighth step adopts a mode of symmetrically welding from the middle to two sides.
In order to ensure that the welding between the box body and each wing plate is firm, the groove type of the welding seam of the long welding seam of the assembling main body is a V-shaped small groove, the angle of the groove on one side of the wing plate of the V-shaped small groove is 10 degrees, and the groove on one side of the box web plate of the V-shaped small groove is formed by the thickness of the web 1/2 plate.
In order to increase the rigidity of the panel and reduce the concave-convex deformation on the plane of the whole panel under the welding action, the panel is welded by adopting intermittent positioning welding, and the adjacent square-shaped partition plates are welded at equal intervals.
In order to increase the rigidity of the panel, the nesting process of the second step has no butt welding seam on the same plate thickness of a single main plate, and in order to improve the assembling precision, the steel plate is added with allowance in the length direction and the width direction;
in order to realize the synchronization of the blanking and the groove and realize one-time cutting, the blanking process of the second step adopts numerical control flame cutting equipment for blanking.
The invention controls heat input in each process of material selection, material sleeving, main material blanking, assembly, welding and flame correction, reduces the influence of steel plate on heating, and is assisted with a semi-automatic welding device, so that the heat input is uniform, and the non-uniformity of deformation is reduced. In addition, the square-shaped technical partition plate is additionally arranged in the box body, and is welded with the panel by adopting intermittent positioning welding, so that the rigidity of the panel is increased, and the concave-convex deformation on the plane of the whole panel under the welding action is reduced. The BOX body is assembled by adopting a plurality of BOX bodies and wing plate combined members in an assembling mode, the BOX body is processed by a BOX (BOX) production line, and meanwhile, a lamellar tearing prevention groove between the BOX body and the wing plate is designed, so that the welding quality and the assembling precision of the members in the whole assembling process are ensured, the cost of the whole project and the manufacturing cost of a factory are saved, and the manufacturing efficiency and the manufacturing precision are greatly improved.
