Embodiment Construction
[0031] Please refer to the attached figure 1 to attach image 3 As shown, the present invention is a method for connecting prefabricated concrete shear wall panels vertically connected by prestressed steel strands. 12 and several parts such as steel strand 3.
[0032] Wherein, the edge vertical steel bars 2 are arranged at edge positions on both sides of the wall body 1 . The wall body 1 leaves a rectangular gap 11 at the bottom of the corresponding position of the edge vertical reinforcement 2 . The lower part of the edge vertical steel bar 2 is exposed in the rectangular gap 11 . A rectangular notch 11 is left at the bottom of the edge of the wall 1, which facilitates the mechanical connection or lapping of the thicker steel bars at this position, and the connection quality of the steel bars is convenient for inspection and acceptance. At the same time, the concrete at the notch 11 can be connected to the wall. The cast-in-place connection parts are poured at the same ti...

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...
