Prefabricated concrete shear wall panel connecting method employing prestressed steel strand for vertical connection

Abstract

The invention relates to a prefabricated concrete shear wall panel connecting method employing prestressed steel strand for vertical connection. The prefabricated concrete shear wall panel connectingmethod employing prestressed steel strand for vertical connection comprises the following steps that a layer of cement mortar for bonding is laid on the floor surface where a wall is about to be mounted, and then the wall is placed in the mounting position in position; a rope is used for being placed from the top of a full-length grouting hole, at an opening, the rope is connected to the end of the reserved steel strand; the steel strand is pulled out of the top of the full-length grouting hole, then the steel strand is enabled to penetrate through a hole in the middle of an anchor plate, a small tensioning jack is used for jacking the anchor plate, and the steel strand is stretched and drawn; after the design elongation is reached, the clamping piece is inserted into a gap between the anchor plate hole and the steel strand for anchoring steel strands, and then the opening in the bottom of the full-length grouting hole is closed, and the cement mortar is injected into the full-length grouting hole until the full-length grouting hole is filled with the cement mortar totally. The vertical connection problem of the prefabricated concrete shear wall panels can be effectively solved.

Description

[0001] 【Technical field】 [0002] The invention relates to a connection method of prefabricated concrete shear wall panels, in particular to a connection method of prefabricated concrete shear wall panels vertically connected by prestressed steel strands, and belongs to the technical field of construction engineering. [0003] 【Background technique】 [0004] Concrete shear wall structures are commonly used in high-rise residential buildings in China, that is, the vertical force-bearing members are concrete walls. As the government vigorously promotes the prefabricated construction method, more and more high-rise concrete shear wall structures are assembled using prefabricated concrete shear wall panels. There are two problems that must be solved during the prefabricated concrete shear wall panel construction: one is the connection of the vertical reinforcement in the precast concrete shear wall panel; the other is the connection of the horizontal concrete joint at the bottom of...

AI Technical Summary

Problems solved by technology

[0005] At present, the connection of vertical steel bars in precast concrete shear wall panels is mainly connected by steel sleeve grouting, but the positioning of steel bars and sleeves is difficult in this method, and the quality of grouting is difficult to guarantee, resulting in many construction quality problems and many criticisms

In addition, the connection of the horizontal concrete connection joints at the bottom of the precast concrete shear wall panels is mainly connected by grouting, but the grouting connection surface is easily disturbed by external forces at the construction site and causes cracks, which seriously affects the connection effect
