Bending-shear stress separated fabricated shear wall and construction method thereof

Abstract

The invention relates to the technical field of fabricated shear walls and discloses a bending-shear stress separated fabricated shear wall and a construction method thereof. A shear wall body in a single floor is formed by vertically splicing unit wallboards, and the adjacent unit wallboards are in tensioned connection through prestressed tendons; downward and outwards convex shear-resisting keysare arranged on the end faces of the bottoms of the unit wallboards, downward and inwards concave shear-resisting grooves corresponding to the shear-resisting keys are formed in the top ends of the unit wallboards, and the shear-resisting keys are matched with and inserted into the shear-resisting grooves of the adjacent unit wallboards below; and a prestressed tendon channel is formed in the shear wall body in the single floor and comprises first slanted channels and second slanted channels which are formed in a crossed mode, the prestressed tendons correspondingly penetrate through the first slanted channels and the second slanted channels, and the prestressed tendons stretch into the other side edges of the adjacent unit wallboards in the oblique diagonal direction of the slanted shearwall body from one side edges of the unit wallboards. The bending-shear stress separated fabricated shear wall is completely distinguished from a traditional connecting mode, stress is definite, overhauling is easy, the controllability of the connecting quality is high, and construction is convenient and efficient.

Description

technical field [0001] The invention relates to the technical field of prefabricated shear walls, in particular to a prefabricated shear wall with separated bending and shear forces and a construction method thereof. Background technique [0002] The prefabricated building is a concrete structure made of prefabricated components, assembled, connected, and partly cast-in-place. It has the advantages of high construction efficiency and low cost, and conforms to the green construction principle of "four sections and one environmental protection". It is the direction of development in the field of civil engineering. [0003] In the current prefabricated buildings, most of the shear walls in one floor are prefabricated as a whole, and then connected with frame beams or frame columns. In the same stress position, it cannot be recovered after damage occurs. Moreover, at present, most of the vertical connections between prefabricated shear walls in prefabricated construction are c...

Problems solved by technology

[0005] The technical problem to be solved is: the existing prefabricated shear wall is prefabricated in one piece with the floor height as the unit, the bending deformation and shear deformation are concentrated, and it cannot be restored after damage, and the traditional grouting sleeve connection method is not easy to control the quality. Time-consuming and labor-intensive, low construction efficiency
