Precast reinforced concrete members and assembled buildings composed of precast reinforced concrete members

The utility model relates to precast reinforced concrete members. The precast reinforced concrete members are joined into walls and reinforcements are erected in the width direction of the adjacent members for reinforcing so as to guarantee the transfer of stress in the horizontal direction. The utility model also provides an assembled building structured by using the precast reinforced concrete members. The precast reinforced concrete members are prefabricated by using concrete; a first through hole is formed in each member in the length direction and a groove is formed in at least one edge of the member and penetrates through the length direction of the edge; when the two edges with the grooves of two members are abutted to each other, the two grooves are abutted to form a closed hole, a plurality of second through holes communicated with the interior of the groove are formed in a sidewall of each groove, while supporting holes corresponding to the second through holes in position are formed in the other si
