Method for manufacturing secondary post-cast ring beam

Abstract

The invention relates to a method for manufacturing a secondary post-cast ring beam for a house filled wall of an elevated duplex building, a hidden duplex building or a building with high floor height. The method comprises the following steps: embedding a U-shaped anchorage rib at one end of a connection component into a main body wall / column, wrapping a joist steel at the other end with a flexible asphalt felt, arranging a flexible polyphenyl board at the end part of the joist steel, binding reinforcement frame upright ribs and reinforcement stirrups at the periphery of the connection component, then inserting the connection component into a ring beam reinforcement framework, filling the flexible polyphenyl board between the two ends of the molded ring beam and the main body wall / column after a support die is cast with concrete, and filling the flexible polyphenyl board or a horizontal sliding layer of the flexible asphalt felt between the lower port of the ring beam and the filled wall. The two ends of the secondary post-cast ring beam manufactured by the method are flexibly connected, and the lower port and the filled wall can freely deform and slide so as to prevent common cracking faults of the filled wall and the painted decorative surface layer and the like, ensure the impression quality of the wall and reduce the rectification cost of the engineering.

Description

technical field [0001] The invention relates to a manufacturing method of a secondary post-casting ring beam for a house filling wall with a raised multi-story, an invisible jump, or a relatively high layer height in the construction of a house construction project. Background technique [0002] In housing construction, for buildings with high ceilings, invisible jumps, or buildings with a large internal height, it is necessary to set a secondary component ring beam in the middle of the infill wall. The secondary ring beam is to build the filling wall to the middle of the inner wall height in the reinforced concrete structure stage of the construction project or after the main body is capped (that is, to build the lower half of the wall in the story first), and then wait for the wall After sinking and stabilizing, formwork is erected on the top surface of the infill wall, steel bars are bound, and ring beam concrete is poured to form a ring beam. Finally, the infill wall is ...

AI Technical Summary

Problems solved by technology

Therefore, after this kind of high-rise double-layer or invisible jump-floor filling wall is built, painted and decorated, quality complaints such as house cracks caused by the secondary pouring ring occur from time to time, causing adverse negative effects on users and increasing Quality Costs of Repair and Rework
