Each unit partition wall panel is comprised of a vertical left frame bar 10, a vertical right frame bar 20, a horizontal top frame bar 30, a horizontal bottom frame bar 40, front and rear face panels 50.

The vertical left and right frame bars 20,30 each have two longitudinal inner sliding grooves 11,21 bilaterally arranged in parallel at an inner side for receiving the face panels 50, a longitudinal inner middle groove 12,22 on the middle at an inner side between the longitudinal sliding grooves 11,21, a longitudinal outer middle groove 13,23 on the middle at an outer side, two elongated slots 131,231 longitudinally aligned within the longitudinal outer middle groove 13,23 near two opposite ends, two pairs of screw holes 133,233 provided at the longitudinal outer middle groove 13,23 and respectively spaced from each elongated slot 131,231 at two opposite ends, and two pairs of round holes 132,232 respectively connected to two opposite ends of each elongated slot 131,231. Further, two first coupling plates 80 are mounted in the longitudinal outer middle groove 13 of the vertical left frame bar 10 and fastened to the screw holes 133, each having a round head pin 81 on the middle.

The horizontal top and bottom frame bars 30,40 each have two longitudinal inner sliding grooves 31,41 bilaterally arranged in parallel at the bottom or top side for receiving the face panels 50, a longitudinal inner middle groove 32,42 on the middle at the bottom or top side between the longitudinal sliding grooves 31,41, a longitudinal outer middle groove 33,43 on the middle at the top or bottom side, two elongated slots 331,431 longitudinally aligned within the longitudinal outer middle groove 33,43 near two opposite ends, two pairs of screw holes 333,433 provided at the longitudinal outer middle groove 33,43 and respectively spaced from each elongated slot 331,431 at two opposite ends, and two pairs of round holes 332,432 respectively connected to two opposite ends of each elongated slot 331,431. The horizontal top frame bar 30 further comprises two screw holes 334 near two opposite ends for the mounting of a second coupling plate 85. When two unit wall panels are abutted against each other, a second coupling plate 85 is fastened to the horizontal top frame bars 30 to fixedly secure the two unit wall panels together.

The horizontal bottom rail 60 comprises a longitudinal top coupling groove 61, a plurality of elongated slots 611 provided at the top coupling groove 61 corresponding to the elongated slots 431 on the horizontal bottom frame bar 40, two pairs of screw holes 613 respectively spaced from the elongated slots 611 at two opposite ends, two pairs of round holes 612 respectively connected to the elongated slots 611 at two opposite ends, and two first coupling plates 80 mounted in the longitudinal top coupling groove 611 and respectively fastened to the screw holes 613, and two vertically spaced longitudinal front coupling grooves 62,63 for the mounting of the bottom rail cover plate 65.
