Abstract
This invention relates to a set of pieces or parts making up a system of metallic adjustable formwork for concrete structures in civil Works which functions is to allow the assembly, junction and adjustment of the formwork system in the most efficient way with the use of a system of adjustable formwork which looks for to use the shorter quantity of metallic panels as accessory during the project execution. The way as the each element has characteristics of specially defined shape, size and function to get a rigid structure, which allow to build a mold over which the concrete is poured maintaining their characteristics and perform such functions rapidly, efficiently and securely.
Claims20
A metallic formwork system for concrete molded structures comprising:
- at least one panel having a smooth front side including a plurality of collinear transversal holes, metallic bands around the periphery of the back side of said panel, said metallic bands also having a plurality of collinear transversal holes and reinforcement elements attached to the back side of said panel;
- a L-shaped corner piece accessory having two perpendicular smooth front sides, each having a plurality of collinear transversal holes, and metallic bands around the periphery of the back side of said L-shaped corner piece accessory, said metallic bands also having a plurality of collinear transversal holes;
- a stop spacer accessory insertable through a collinear transversal hole on the smooth front side of said panel;
- an aligner accessory having an opening, at least one aligning screw accessory having one threaded end insertable through the opening of said aligner accessory and the other end attachable to at least one of:
- said metallic bands and said reinforcement elements of said back side of the panel;
- a pin bolt insertable through at least one of:
- a hole of said collinear transversal holes of the smooth front of said panel, a hole of said collinear transversal holes of the metallic bands of said panel, a hole of said collinear transversal holes of the smooth front of said L-shaped corner piece accessory, and a hole of said collinear transversal holes of the metallic bands of said L-shaped corner piece accessory, said pin bolt having a cylindrical form and a slot centered along said cylindrical form;
- a L-shaped smooth profile having a plurality of pins insertable through the collinear transversal holes of said metallic bands, said plurality of pins having a cylindrical form and a slot centered along said cylindrical form;
- a L-shaped corner piece angle having two perpendicular sides, each having a plurality of longitudinally collinear transversal holes;
- a concave-shaped wedge insertable through at least one of:
- the slot of said pin bolt and a slot of the pins of said L-shaped corner accessory;
- and
- a plate having a rectangular shape, said plate being folded at an angle and having an axially receiving pass-through slot, and a linking pin attached to said plate.
