摘要： An interlocking device (10) is adapted to lock two modular building formworks (8). Each formwork (8) includes a wall plate (81) and a frame (82). Each frame (82) has aligning and locking holes (821, 822). The interlocking device (10) includes a housing unit (1) secured to the frame (82), a rotation transferring unit (2) having intersecting input and output shafts (212, 222), a transmitting unit movably coupled with the output shaft (222), and a locking member (6) having a head portion (61), a positioning portion (62) and a threaded portion (63). The locking member (6) is insertable into the aligning hole (821) of one frame (82) to have the head portion (61) abutting against the frame, and the threaded portion (63) is matingly engageable in the locking hole (822) of the other frame (82) so as to lock the two formworks (8).

摘要： A modular building formwork apparatus includes a formwork wall (8) and at least one interlocking device (10). The formwork wall (8) includes a wall plate (81) and a frame (82) disposed on the wall plate (81). The frame (82) has an aligning hole (821) and a locking hole (822). The interlocking device (10) includes a housing unit (1), a rotation transferring unit (2), a transmitting unit (3) and a locking member (6). The rotation transferring unit (2) has an input shaft (212) and an output shaft (222). The transmitting unit (3) is movable relative to and rotatable about the output shaft (222). The locking member (6) has a head portion (61), a positioning portion (62) and a threaded portion (63). The locking member (6) is insertable into the aligning hole (821) to permit the threaded portion (63) to threadedly engage in the locking hole (822).

摘要： A building formwork apparatus (100) includes a building formwork (2) having a frame (22) with a positioning hole (221) and a locking hole (222), and a locking member (1, 1') including a first tapered section (131), a second tapered section (132) connected to the first tapered section (131), and a threaded portion (14) connected to the second tapered section (132). The positioning hole (221) is configured to receive insertion of the locking member (1, 1') therethrough such that the first tapered section (131) is retained therein and the second tapered section (132) is exposed therefrom for connection with another building formwork apparatus (100). The locking hole (222) is configured to receive a threaded portion (14) and a second tapered section (132) of a locking member (1, 1') of the another building formwork apparatus (100) .
