Abstract
A one-way retractable building formwork apparatus for mounting on a mounting surface of a substrate module includes a first side bar disposed on one end of the mounting surface that extends along a lateral direction, a second side bar disposed on another end of the mounting surface and opposite to the first side bar along an extending direction transverse to the lateral direction, and a retractable unit that is disposed on the mounting surface, that is connected to the first side bar, and that is extendable along the extending direction to fixedly connect to the second side bar.

A one-way retractable building formwork apparatus for mounting on a mounting surface of a substrate module, comprising:
- a first side bar configured to be disposed on one end of the mounting surface that extends along a lateral direction;
- a second side bar configured to be disposed on another end of the mounting surface that extends along the lateral direction and opposite to said first side bar along an extending direction transverse to the lateral direction;
- and
- a retractable unit configured to be disposed on the mounting surface and connected to said first side bar, said retractable unit being extendable along the extending direction to fixedly connect to said second side bar.
A one-way retractable building formwork apparatus for mounting on a substrate module which includes a first substrate and a second substrate adjacently connected to each other along an extending direction, the first substrate having a first surface, the second substrate having a second surface, said one-way retractable building formwork apparatus comprising:
- a first side bar configured to be disposed on one end of the first surface that extends along a lateral direction transverse to the extending direction;
- a second side bar configured to be disposed on one end of the second surface that extends along the lateral direction and opposite to said first side bar along the extending direction;
- and
- a retractable unit configured to be disposed on the first surface and connected to said first side bar, said retractable unit being extendable along the extending direction to fixedly connect to said second side bar.
