The present invention relates to a formwork metallic for the molding in concrete in construction works and substructure. The invention is easy handling for uses numerous, with characteristic modular to facilitate the connection the connection between them by means accessories metallic. These formworks metallic are modules which form steel sheets with reinforcements and in size according the requirements in work.
This formworks by its vicinity them, gives the form to concrete, specially walls and partition walls.
The formwork is made in steel sheet (2 to 3 mm thick) and the modules formed can have a weight to 43 kg (60×240 cm) and dimensions which varies from 5 to 80 cm in wide and from 20 to 240 cm in height, with increasing scales of 5 cm in the measures.
The characteristic and advantages in the formwork of the present invention appear more clearly on reading the following description given by away of non limiting indication and made with reference to the accompanying drawings, in which
Each member or prop 12 which surrounds the sheet 11 has in the length holes 14 spaced equidistant. The plane surface sheet 10 is reinforced with metallic elements 15 with profile in V, and in the wide has a reinforcements or struts 16 perpendiculars to previous. The module or formwork couples or splice with others similar through an angular profile 17 (
The angle 17 has the same length as module 10 and comprises holes in his faces. The modules (formworks) keeps during installation a distance parallel with other module, where said space enables to empty the concrete to form the wall or partition walls in the respective building.
Other elements to couple is the named corner cupboard module, type box 28 (
The coupling between adjacent modules (
When two modules are installed, it's proceeded to an alignment to provide verticality them and structural stiffness, through an element to align 21 (
The linkage between modules, it's complemented through linkage elements or sheets 25 (
An element placed in the corners in the module or formwork, type sure plate, welded there, enables the passage to pin 20, so to assure the distancing or “tie” 18 to adjacent module.
The modules of the present invention can be installed in order the following prescriptions:
The face smooth in the formwork is coated with substance for removing the timbering before to empty the concrete, to avoid the adherence of said concrete in the formwork. This coat is washed with pressure when the empty is finished.
The stuffiness in the formwork is secured by means of cotter pins for the distancing and sheets in the holes in the frame of module. This module was making in sizes of 240 cm in length and wide from 5 to 80 cm. The corner cupboard has from 20 to 240 cm in length at same the angles for external turn.
The weight of module according the measures selected varies from 3 kg (5×120 cm) to 43 kg (60×240 cm).
An advantage of present invention is the low weight and easy use, and transport. Since the basic module don't exceeds the kg although modules with 240×60 cm can weigh 43 kg, factor easy usable for any worker.
The module provides a smooth finished or textured of concrete in view.
Can be built the name “irregular modules” in sizes when the circumstances it required.
Manual installation without need of crane towers.
Easy transport to work or building given it form as boxes.
Drawing according regulation seismic NSR-98.
Avoid waste or scraps and rubbles.
The employees enable the control of tools and materials in work.
To enable the reuse, given the characteristic metallic.
Cheap manufacturing costs.
Uses versatile to built homes or public works.
The formwork is washable after empty and removed from wall.
The formwork is storable with in small space.
