Description

FORMWORK FOR HOUSING CONSTRUCTION

OBJECT

This invention has as its object a metal formwork for the construction of single-family or multi-family houses, which facilitates the construction of said houses in a very short time compared to that of traditional construction.

The industrial sector to which this invention belongs is that of

building formwork.

BACKGROUND OF THE INVENTION

Formwork can be essentially of two types, traditional,

commonly made of wood and metal.

The most important constitutive elements are: a) Wooden formwork: Planks, slats and struts. b) Metal formwork: Panels, staples, stabilizers, brackets and lifting hooks.

Other materials used are plastic and plasticized cardboard.

Formwork forms round columns and pillars

basically.

The use of traditional wooden formwork tends to disappear due to its cost and lower yields compared to prefabricated formwork.

Metal formwork is supplied by companies

specialized, and the most appropriate system is chosen based on the needs or processes of the work planned. The two main types of metal formwork are double-sided wall formwork and pillar formwork.

The two-sided wall formwork is a robust formwork usually formed by a metal frame with a formwork face made of wood or sheet, for the construction of walls with formwork on both sides, usually of large surface.

The formwork of pillars as well as the formwork of walls can be formed by a metal frame with a formwork face made of wood or sheet, for the construction of square or rectangular pillars, with formwork on all four sides.

There are currently many types of formwork, each with its specific characteristics and functions, described below.

a formwork for the construction of houses in a minimum time.

DESCRIPTION OF THE INVENTION

PROBLEM PLANTAMENT: It is about building houses in

very little time, economical and easily buildable, unused

Bricks for the construction of exterior walls.

ADOPTED SOLUTION: The solution consists of a type of formwork

Modular vertical whereby the four exterior walls of one or two houses are built simultaneously in a single wash, being

these made of concrete. If it is a building, the procedure is repeated on each floor. The floor slabs are constructed with prefabricated annealed slabs and compression layer.

This modular vertical formwork for the construction of annate concrete walls of 12 cm thickness and 270 cm maximum height, is

characterized by being a temporary auxiliary structure, which serves

to mold fresh concrete resisting all efforts

caused by the horizontal pressures of horrifying, until the

concrete sets and reaches its characteristic resistance.

This provisional structure is made up of panels of

S

formwork, connection and fixing elements and by a series of

additional components, necessary to perform the different

formwork and formwork operations under optimal conditions of

security. Its description is as follows:

PREFERRED EMBODIMENT OF THE INVENTION

Among the different embodiments of this invention, the

Preferred is as described below:

Starting from a previously constructed concrete slab, the formwork necessary to build the exterior walls (4) of two houses of 50 m 'each, is made with a formwork, consisting of a set of exterior metal panels and two sets of panels

metallic interiors, whose shape is determined by:

a) An outer drawer (1) rectangular.

b) Two interior drawers (2) rectangular and equal. e) Removable molds (3) for shaping the opening of the

doors and windows.

All these panels are made with 3 mm steel plate

and metal profiles. In order to withstand the strong pressures exerted by the concrete on the panels that make up the formwork drawers,

said panels are held by threaded steel bars, which

placed inside a PVC tube with a diameter slightly larger than that of said bar, which facilitates its extraction during decoupling.

At the ends of said balls placed perpendicular to the surface of the mentioned panels, washers and nuts are placed,

that allow to fix them and avoid their deformation. These bars are spread over the entire surface of the panels.

To configure the doors and windows planned according to the project,

are inserted in the space between the outer drawer (1) and interior (2), removable molds for door or window (3). This

way when pouring concrete into the formwork, the opening for

said doors or windows, is perfectly shaped, which facilitates its assembly by previously placing the frames and then the flashing.

The floor is constructed with precast reinforced concrete honeycomb slab and compression layer. The distribution of each home is

subsequently performed in a traditional way, providing as appropriate

that is the user himself who performs it since it is housing

social.

With this type of formwork you can build a building with up to four floors, repeating the same assembly process.

The formwork is complemented with stairs and indoor and outdoor work platforms.
