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.
Claims8
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 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;
- wherein said retractable unit includes:
- two side bar modules extending along the extending direction and configured to be disposed on another two opposite ends of the mounting surface that extend along the extending direction such that said side bar modules are opposite to each other along the lateral direction, said side bar modules being fixedly connected to said first side bar,
- a fixed plate assembly configured to be disposed on the mounting surface between said first side bar and said second side bar, and
- a side plate assembly inserted into said fixed plate assembly and extendable out of said fixed plate assembly along the extending direction to fixedly connect to said second side bar, said side plate assembly including a plurality of side plates telescopically connected to one another, an outermost one of said side plates being slidably engaged with said fixed plate assembly, an innermost one of said side plates being slidably engaged with and being extendable out of an adjacent one of said side plates to fixedly connect to said second side bar.
