As shown in fig. 1-2, the prefabricated reinforced concrete shear wall provided by the utility model comprises a wallboard 1 and a supporting rod mechanism 2, wherein the supporting rod mechanism 2 comprises a supporting rod sleeve 21 and a supporting rod 22, and the supporting rod mechanism 2 can support the wallboard 1 as shown in fig. 1 or can be stored in the wallboard 1 as shown in fig. 2.

As shown in fig. 3-5, the bottom end of the supporting rod sleeve 21 is movably sleeved with the top end of the supporting rod 22, the top end of the supporting rod sleeve 21 is fixedly connected with 211, the surface of the wallboard 1 is fixedly connected with a first fixing seat 23, and the first fixing seat 23 is rotatably connected with the supporting rod sleeve 21 through a rotating shaft. The inside elastic connection of vaulting pole 22 has a pair of connecting rod 25, fixedly connected with guiding axle 26 between the inner wall of vaulting pole 22, and connecting rod 25 has offered the through hole 251 that supplies guiding axle 26 activity to run through, and wherein two guiding axle 26 all overlap and be equipped with spacing spring 27, and spacing spring 27's both ends respectively with the connecting rod 25 fixed connection of corresponding position. The top end of each connecting rod 25 is fixedly connected with a first limiting clamping block 24, and the supporting rod sleeve 21 is provided with a second limiting clamping block 212 which can be clamped in by the first limiting clamping block 24. A shaft handle 28 is fixedly connected to one side of the bottom end of the connecting rod 25, and the shaft handle 28 movably penetrates through the supporting rod 22. The outer wall of the stay bar 22 is fixedly connected with a positioning sliding block 221, the inner wall of the stay bar sleeve 21 is provided with a positioning sliding groove matched with the positioning sliding block 221, and the positioning sliding groove is parallel to the central shaft of the stay bar sleeve 21.
