Abstract
A two-way retractable building formwork apparatus includes a substrate module having a mounting surface, a first side bar mounted on one end of the mounting surface that extends along a first direction, a second side bar mounted on another end of the mounting surface that extends along a second direction transverse to the first direction and fixed to one end of the first side bar, a first retractable unit mounted on the mounting surface opposite to the first side bar and extendable along the first direction to fixedly connect to the second side bar, and a second retractable unit mounted on the mounting surface opposite to the second side bar, extendable along the second direction to fixedly connect to the first side bar, and further connected to the first retractable unit.
Claims5
A two-way retractable building formwork apparatus, comprising:
- a substrate module having a mounting surface;
- a first side bar mounted on one end of said mounting surface that extends along a first direction;
- a second side bar mounted on another end of said mounting surface that extends along a second direction transverse to the first direction and fixed to one end of said first side bar;
- a first retractable unit mounted on said mounting surface opposite to said first side bar and extendable along the first direction to fixedly connect to said second side bar;
- and
- a second retractable unit mounted on said mounting surface opposite to said second side bar and extendable along the second direction to fixedly connect to said first side bar, said second retractable unit being further connected to said first retractable unit;
- wherein said first retractable unit includes a third side bar, a fixed plate assembly, and a side plate assembly, said third side bar extending along the first direction, being mounted on a third end of said mounting surface that is opposite to said one end of said mounting surface, and being fixed between one end of said second side bar that is opposite to said one end of said first side bar and said second retractable unit, said fixed plate assembly being mounted on said mounting surface between said second side bar and said second retractable unit, said side plate assembly being inserted into said fixed plate assembly and being extendable out of said fixed plate assembly along the first direction to fixedly connect to said second side bar, said side plate assembly being fixed to said mounting surface.
