Abstract:
1. A protective wall board assembly for houses, including: two “␣” shaped columns having an opening and a guiding slot communicating with the opening; a corresponding first arm and a second arm provided on the “␣” shaped columns; a bent section which bends toward the inside of the guiding slot being connected to the first arm at a position near the opening and terminating before the bottom of the “U” shaped column, in which a spacing is formed between the bent section and the first arm, so that the bent section has a flexible moving space, a protruding rib which protrudes toward the first arm being connected to the second arm at a position near the opening; a plurality of hollow flat plates each having an upper end portion, a lower end portion, and two side end faces, in which the width between the two side end faces is slightly smaller than the width of the opening; and a first engaging portion and a second engaging portion being provided on the upper end portion and the lower end portion of the hollow flat plates respectively; in which the two ends of the hollow flat plates are accommodated in the guiding slot of the “␣” shaped columns respectively, two adjacent hollow flat plates are fixedly joined with the engagement between the first engaging portion and the second engaging portion, and the hollow flat plates are fixed between and contact the bent section and the protruding rib; in which a protrusion which protrudes toward the first arm is connected to the second arm, the position of the protruding rib is farther away from the opening than that of the protrusion, in which a recessed slot is formed between the protruding rib and the protrusion, the recessed slot corresponds to the bend section for accommodating one resilient soft tube which tightly contacts a side end face of the hollow flat face so as to achieve a hermetic effect between the second arm and the hollow flat plates; in which the resilient soft tube can be moved between the protrusion and the protruding rib on the recessed slot when the hollow flat plate is being moved.
