[0061] An operation method of a connection node between a steel beam and a multi-cavity steel plate shear wall is carried out according to the following steps:
[0062] (1) Preparation of steel plate shear wall:
[0063] Select steel plates of the same specification, assemble several steel plates into a multi-cavity box according to the requirements of the drawings, and use groove welding between the steel plates to test the integrity and surface smoothness of the welding joints;
[0064] Before the parts are processed, three-dimensional lofting by computer and CNC cutting and blanking are used to ensure the accuracy of the parts. Before the parts are cut, the steel plate is overall leveled to eliminate the deformation of the steel plate, reduce the internal stress of rolling, and reduce the damage during the manufacturing process. Deformation, the necessary process to ensure the flatness of the plate;
[0065] (3) Preparation of steel beam components:
[0066] According to the requirements of the drawings, assemble the steel beams, and the upper part of the web plate and the upper flange plate, and the bottom part of the web plate and the lower flange plate are respectively fixed by welding;
[0067] (3), set the angle steel components in the steel plate shear wall:
[0068] According to the actual requirements, several angle steel components are arranged in the steel plate shear wall, and symmetrically distributed angle steels are arranged on both sides of the inner wall of the steel plate shear wall, and the outer walls of the angle steel are connected by fixing plates;
[0069] (3) Install the stiffening components in the steel plate shear wall:
[0070] 1. When the stiffening assembly includes the upper stiffening partition and the lower stiffening partition:
[0071] The upper stiffening partition is arranged at the upper end of the steel plate shear wall end unit, and the lower stiffening partition is arranged at the lower end of the steel plate shear wall end unit; The outer wall of the wall is welded, and one side is welded with the longitudinal partition. The upper and lower stiffening plates are located on the inner side of the outer wall of the shear wall or pass through the outer wall of the shear wall; when the end unit is H-section steel, the upper and lower stiffening plates are welded with the H-section steel flange plate and web plate on three sides. ;
[0072] The upper stiffening clapboard and the lower stiffening clapboard are fixed to the steel plate shear wall through the same longitudinal partition;
[0073] Or, the upper stiffened partition and the lower stiffened partition are respectively fixed to the steel plate shear wall through longitudinal partitions;
[0074] 2. When the stiffening component includes upper and lower anchor bars:
[0075] When the end unit is a shear wall cavity unit, two upper anchor bars are installed along the horizontal direction on the shear wall end unit panel near the upper flange of the steel beam, and the shear wall end unit panel is close to the lower wing of the steel beam Two lower anchor bars are arranged at the position of the edge along the horizontal direction, and divergent anchor bars are respectively arranged above and below the upper anchor bars and above and below the lower anchor bars; the anchor bars are welded and connected to the shear wall plate after bending.
[0076] (5) Assembly of steel plate shear wall and steel beam components:
[0077] The outer wall of the end unit of the steel plate shear wall is welded and fixed with the upper flange plate and the lower flange plate respectively. The corresponding welding seam should be provided with arc ignition and lead-out plates at both ends of the welding seam. After welding, the arc ignition and Lead-out board, and repair and level;
[0078] The outer wall of the end unit of the steel plate shear wall is provided with a connecting plate, and the connecting plate and the web are fixed by bolts; the contact surface of the connecting plate and the web within the range of high-strength bolt connection shall be sandblasted or shot blasted, and the anti-slip coefficient shall be To meet the design requirements, the anti-slip coefficient test should be done before construction, and the test report should be submitted;
[0079] (6), pouring concrete:
[0080] The concrete used for pouring can be ordinary concrete, high-strength concrete, lightweight aggregate concrete or self-compacting concrete. The concrete should take technical measures to reduce shrinkage. There should be enough blanking space for pouring, and the concrete should fill the entire cavity. The pouring speed and single blanking amount shall be poured to the top in layers within the allowable range of the maximum pouring height of the concrete;
[0081] When the end element of the steel plate shear wall is H-beam, the end element of the steel plate shear wall does not need to be poured concrete;
[0082] (6), detection intensity:
[0083] Test the concrete pouring results in the shear wall to see if there is a hollow; test the connection welds to ensure the reliability of the welds; test the connection status of the high-strength bolts to ensure that they meet the technical requirements of high-strength bolts.
