A horizontal connection node of prefabricated shear wall

Abstract

The invention discloses a horizontal connection node of a prefabricated shear wall. The horizontal connection node comprises an upper wall plate (3), a grouting area (2) and a lower wall plate (8), wherein the upper wall plate (3) and the lower wall plate (8) are connected through the grouting area (2); and a grouting anchor area (1) with a predetermined weight is arranged at the lower end of the upper wall plate (3). Through a novel connecting form of arranging a plurality of upper wall plate notches (5) in the end, close to the grouting area (2), of the grouting anchor area (1), arranging a plurality of lower wall plate notches (6) in the end, close to the grouting area (2), of the lower wall plate (8) and arranging jackets (9) outside vertical reinforcements with predetermined lengths at the upper end of the lower wall plate (8) to form unbonded sections (7), the horizontal connection node has the advantages of excellent bearing capacity and energy dissipation capability, convenience for construction and low cost, realizes the bearing capacity requirement and the energy dissipation requirement of the prefabricated shear wall under the effect of horizontal load through the notches and the unbonded sections, and is widely applied to a high-intensity area.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a prefabricated shear wall horizontal connection node adopting a slot-type unbonded connection technology. Background technique [0002] Prefabricated shear wall structure is one of the effective ways to realize building industrialization and residential industrialization. For a long time, concrete buildings mainly adopt the traditional construction method of on-site wet operation, which has a low degree of industrialization, water consumption, energy consumption, artificial waste, sewage The amount of emissions is large, which is not in line with the national sustainable development policy of energy conservation and environmental protection. The prefabricated structure can be prefabricated in the factory and assembled on site to realize the industrialization of housing. At the same time, it can effectively improve the utilization efficiency of materials, save resourc...

Problems solved by technology

[0011] In summary, the current connection forms of prefabricated shear walls are all used in general intensity areas, but there is no special research on the connection forms based on grout anchors applied in high intensity areas.
