Assembly connecting structure and assembly connecting method of assembled concrete frame and shear wall combination

Abstract

The invention relates to the field of assembled concrete structures, in particular to an assembly connecting structure and an assembly connecting method of an assembled concrete frame and shear wall combination. A cast-in-place strip is disposed between precast columns and precast shear walls to connect column-wall embedded rebars. Vertical through holes are reserved in a precast node-precast beam integrated component to achieve communicated connection of vertical rebars for the upper and lower columns and the upper and lower shear walls. Embedded steel sleeves at the lower ends of the precast columns and the precast shear walls are mutually embedded with projecting rebar segments extending up out of the lower columns and the lower walls, and are integrated with the lower columns and the lower walls through cast mortar. The projecting straight rebars at the upper ends of the precast columns and the precast walls penetrate through the through holes reserved in the precast node-precast beam integrated component and protrude a floor slab, and the precast columns and the precast nodes are firmly integrated with the precast shear walls precast beams by cast mortar. Wet operations such as in-place casting of concrete are reduced to the maximum extent, building quality is improved, construction period is shortened, and energy conservation and emission reduction are achieved.

Description

【Technical field】 [0001] The present invention relates to the field of prefabricated concrete structures, specifically a prefabricated assembly type or assembly integral type (hereinafter referred to as assembly type) concrete frame-shear wall structure consisting of prefabricated columns, prefabricated walls, prefabricated nodes and prefabricated beams. Sub-assembly system, component connection structure, structures built by this assembly system and connection structure, and assembly connection methods. 【Background technique】 [0002] The existing technology of prefabricated concrete structure is limited to pure frame structure and pure shear wall structure, and the prefabricated concrete frame-shear wall structure composed of prefabricated columns, prefabricated walls, prefabricated nodes and prefabricated beams has not yet been published. Compared with pure frame structure or pure shear wall structure, since the concrete frame-shear wall structure is a combination of wire...

AI Technical Summary

Problems solved by technology

The conventional method of the prefabricated frame structure is to prefabricate the beams and columns, and the nodes are cast-in-place. The main problem is that the steel bars of the beams and columns in all directions are intersected, intersected, connected and anchored in the core area of ​​the nodes, which makes the reinforcement construction difficult and difficult to ensure the construction quality of the nodes.

The current practice of the prefabricated shear wall structure is that the vertical reinforcement of the upper and lower walls is lapped with reinforced grout anchors in reserved holes, and the horizontal reinforcement of the left and right walls is lapped with cast-in-place belts. The main problem is that the vertical reinforcement is generally double-faced. There are too many roots and the length of the lap joint is long, which is not convenient for construction
