Claim 6

A joint structure for panels in prefabricated housing comprising: a. a pair of first vertical wall panels arranged in alignment with each other and each comprising a pair of first vertical plates spaced in parallel with each other, a first vertical frame member having a rectangular cross section, effecting connection between the first vertical plates and disposed at that side end of the vertical plates which faces the adjacent first vertical wall panels, horizontally extending pipes for electric wires each having one end passing through the first vertical frame member, a first vertical columnar joint member fixed to the outer surface of the first vertical frame member and the inner surface of the vertical plate which is aligned with one of the vertical plates of the adjacent first vertical wall panel, extending from the inner surface to the substantially central line of the first vertical frame member and abutting against the first columnar joint member of the adjacent wall panel, said first vertical frame members and first vertical columnar joint members of both the first vertical wall panels defining a generally U-shaped recess; b. a second vertical wall panel disposed perpendicular to the first vertical wall panels and comprising a pair of second vertical plates, a second vertical frame member having a rectangular cross section, effecting connection between the second vertical plates and disposed at that side end of the second vertical plates which is adjacent to the recess in the first vertical wall panels, said side end of the second vertical plates and the second vertical frame member defining that side end of the second vertical wall panel which is complementary to the recess, and horizontally extending pipes for electric wires each having one end passing through the respective frame members; and c. horizontally extending notch-shaped connecting chambers provided in the second vertical frame member so as to cause the pipes of the first and second vertical wall panels at the same level to communicate with each other.

Claim 7

A joint structure for panels in prefabricated housing comprising: a. a pair of vertical wall panels arranged perpendicular to each other with one of the side ends of one of the wall panels connected to one of the side ends of the other wall panel and each comprising i. a pair of vertical plates spaced in parallel with each other, ii. a vertical side frame disposed at said one of the side ends and comprising a vertical frame member having a rectangular cross section, disposed between said vertical plates for connection therebetween, and a columnar joint member fixed to the outer surface of the vertical frame member and the inner surface of the vertical plate so as to extend from the inner surface to the substantially central line of the vertical frame member, the adjacent sides of the vertical frame member and the columnar joint member defining an L-shaped recess, the columnar joint member of one of the wall panels having a complementary shape to the recess of the other wall panel so as to be received therein, and iii. horizontally extending pipes for electric wires each having one end passing through the vertical frame member; and b. horizontally extending notch-shaped connecting chambers provided in the vertical frame member of one of the vertical wall panels so as to cause the pipes of the vertical wall panels at the same level to communicate with each other.

Claim 8

A joint structure for panels in prefabricated housing comprising: a. a pair of vertical wall panels arranged perpendicular to each other with one of the side ends of one of the wall panels connected to one of the side ends of the other wall panel and each comprising i. a pair of vertical plates spaced in parallel with each other, ii. a vertical side frame disposed at said one of the side ends and comprising a vertical frame member having a rectangular cross section, disposed between said vertical plates for connection therebetween, and a columnar joint member fixed to the outer surface of the vertical frame member and the inner surface of the vertical plate so as to extend from the inner surface to the substantially central line of the vertical frame member, the adjacent sides of the vertical frame member and the columnar joint member defining an L-shaped recess, the columnar joint member of one of the wall panels having a complementary shape to the recess of the other wall panel so as to be received therein, and iii. horizontally extending pipes for electric wires each having one end passing through the vertical frame member; and b. horizontally extending notch-shaped connecting chambers provided in the vertical frame member of one of the vertical wall panels so as to cause the pipes of the vertical wall panels at the same level to communicate with each other.
