Construction method of rigid connection joint structure of steel connecting beam-partially encased composite (PEC) jointed limb wall

Abstract

The invention relates to a construction method of a rigid connection joint structure of a steel connecting beam-partially encased composite (PEC) jointed limb wall. The construction method comprises the following steps that (1), a steel skeleton member is first welded and formed in a factory; (2), steel connecting beams I are welded to H-shaped steel of the steel skeleton member; (3), a transverse stiffening plate is welded to the positions, close to the steel connecting beams I, between flanges of the H-shaped steel, and a vertical stiffening plate is welded to the steel connecting beams I; (4), stirrups are welded into the H-shaped steel and welded to the two sides of webs; (5), the steel skeleton member is placed on the ground and concrete is poured; (6), the other half of a PEC shear wall II is machined according to the above process; and (7), the PEC shear wall is transported to a construction site, the steel connecting beams I and steel connecting beams II are connected in a butting mode, and connecting plates and bolts are installed to enable a PEC shear wall and the PEC shear wall II to be connected. According to the construction method of the rigid connection joint structure of the steel connecting beam-PEC jointed limb wall, the connection of the PEC shear wall and the steel connecting beams is realized, and a novel PEC jointed limb wall is formed. The PEC shear wall and the steel connecting beams both can be pre-formed in the factory, and thus on-site construction labor-hours is greatly reduced.

Description

[0001] 【Technical field】 [0002] The invention relates to a connection method of a building wall, in particular to a construction method of a rigid connection node structure of a steel connecting beam-PEC combined limb wall, and belongs to the technical field of construction engineering. [0003] 【Background technique】 [0004] Partially Encased Composite Shear Wall (hereinafter referred to as PEC shear wall) is a composite section made of I-beam or hot-rolled thin steel plate, and transverse tie bars are set at a certain distance between the flange and the web. The components can be processed in the factory, and only spliced ​​and installed on site, which can effectively reduce the construction period on the basis of ensuring the construction quality of the components, and has good economic effects.
