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.
Claims15
1- Metallic formwork system for concrete molded structures with its own accessories characterized because it has panels that allow the graduation o the formwork with collinear transversal intermediate holes in the smooth front side of each panels and pins that fit in the transversal holes for the intermediate graduation and combination of shapes that molds different size structures with the same panels and with elements of adjustment such as welded pins profiles, corner pieces an accessories with stops that guaranty an uniform width o the concrete structure segments.
2- Metallic formwork system for concrete structures according to claim 1 characterized because each panel has in the smooth side collinear transversal intermediate holes in lengthwise and widthwise of a metallic sheet that allow making different graduations depending on the edge of the panel to be joined, varying its length with respect to the first perforation near to each edge when the panels position perpendicularly to form the formwork.
3- Metallic formwork system for concrete structures according to claim 1 characterized because the metallic panel on its back side has reinforcement with L-shaped angles transversally welded that stand the force of the transversal holes pins that allow the graduation of the perpendicular panels and has slots in the interprofiles with the L-shape perpendicular reinforcement or the pass of the wedge adjusting the pin.
4- Metallic formwork system for concrete structures according to claim 1 characterized because the metallic panel on his back side has bands with metallic holes that are longitudinally welded reinforcement and on its back side has rods welded to longitudinal metallic bands allowing the manipulation and management by the user for its assemble.
5- Metallic formwork system for concrete structures according to claim 1 characterized because the spacer is composed of three elements:
- a rod of circular profile with stop cassette decks tope in a end and a partially threaded end in the other end that adjusts to a nut that has a stop guide and a wench to tight that guaranty an uniform width of the concrete structure segments that molds between panels.
6- Metallic formwork system for concrete structures according to claim 1 or 6 characterized because the spacer rod has in one of its ends a stop cassette deck as a measure for the distance between the panel and other perpendicular perforated stop cassette deck welded to the cassette deck to remove the rod without damaging the molded structure.
7- Metallic formwork system for concrete structures that use an aligner accessory according to claim 1 characterized because the aligner assembles to a J-shaped pin screw or with other Y-shaped screw with two flanges and a pin that adjust the crossbar to the metallic panel through another complementary accessory called adjustment nut which tightens the J-shaped or Y-shaped screw with two flanges
8- Metallic formwork system for concrete structures that use an aligner accessory according to claim 1 characterized because the J-shaped pin screw is folded with an obtuse angle to form the hook and allow that the smooth folded end introduces in the holes o the lateral metallic band of the panel and the Y-shaped screw with two flanges allow joining the formwork panels without the possibility of leaving spaces between the joints.
9- Metallic formwork system for concrete structures according to claim 1 characterized because the opposite end of the J-shaped pin screw and the opposite end of the Y-shaped screw with two flanges have a thread up to its middle profiles to thigh the adjustment nut tightens up tot its stop to guaranty the width of the structure segment to be molded.
10- Metallic formwork system for concrete structures according to claim 1 characterized because the adjustment nut complementary of the J-shaped pin screw and the Y-shaped screw is composed of a welded washer, a internally threaded cylinder with stop to determine the length of the spacers between the walls.
11- Metallic formwork system for concrete structures according to claim 1 characterized because el adjustment screw with two Y-shaped flanges have holes in each flanges to allow the pass of a pin that secures the screw to the lateral, vertical or horizontal walls of the joined panels, which allow the intermediate hooking in the perforated reinforcement for the vertical or horizontal joints.
12- Metallic formwork system for concrete structures which uses a pin bolt with head according to claim 1 characterized because the pin has a step that adjusts when the panels are placed in a graduated position.
13- Metallic formwork system according to claim 1 characterized because the panels with transversal collinear holes, the profile with welded pins and the system corner piece allow creating structures with the shape of columns, channels, protuberances, T-shaped walls and L-shaped walls with adjustable adjustment accessories that guaranty the uniform width or each segment of the structure and allow creating 77 possibilities of graduation outdoors, 23 combinations inner wall to 180° and 12 combinations inner wall to 90°, when they graduate to each of the panels with different holes.
14- Metallic formwork system according to claim 1 characterized because the panels with transversal collinear holes allow a total of 112 possibilities using our profile panels with 0.60 width and equidistant holes every 10 centimeters as their corresponding accessories.
15- Metallic formwork system according to claim 1 characterized because the right angle profile with welded holes has holes and pins that align with the holes of the panels to be joined to avoid deformations of the structure to be molded and because the welded pins configure the corner pieces of different sizes without the need of completing with compensatory pieces and are demountable to use as the panels as the welded pins profile in other functions or configuration of the measurements of the walls to be melted.
