Benefits of technology

[0014] It is therefore a main object of the present invention to provide a low cost prefabricated wall panel.
[0016] It is still another main object of the present invention to provide a prefabricated wall panel having the above disclosed nature, which is fire proof, very light, has a high resistance and a very low cost, ideal for build or modify low resources homes or budget constructions.
[0017] It is another object of the present invention to provide a prefabricated wall panel having the above disclosed nature in which, the internal cardboard core acts as a sound and thermal insulator, which helps to lower the energy consumption used for cooling and heating inside the construction.
[0018] It is a further object of the present invention to provide a prefabricated wall panel having the above disclosed nature in which the external fire proof covering provides security in its use and weather or humidity resistance, thus prolonging the useful life of the wall panel.

Problems solved by technology

The space divider disclosed by the Pat. No. 4,706 422, as well as many of the wall panels currently in the market, have a relatively complex internal structure which use expensive materials and need qualified workmanship for its assembly, which raises the total cost of the wall panel.
Such kinds of wall panels, given its high cost, are more suited for residential and commercial use, and its acquisition by low resources individuals or entities is very difficult.
In countries under development or undeveloped, it is very usual that in zones having high poverty rates, the houses are built of inadequate, unsuitable and dangerous materials, such as cardboard, iron sheets and waste material.

example 1

[0040] A prefabricated wall panel in accordance with the present invention having a size of 35.4″×47.24″×1.96″and a metallic grid including four horizontal rods and 3 vertical rods each having a size of ½″×½″ forming six quadrangular cells, was submitted to a test for determining its charge capacity when applying a flexing force.

[0041] The test was carried out by placing the wall panel over four metallic perimetric supports each having a width of 5″. The force was evenly applied to each cell by means of two iron plates longitudinally placed over the wall panel so each plate contacted a row of three quadrangular cells, each plate having a size of 9.84″×9.84″×1″. A downward force was applied to both plates by means of a pair of two elongated metallic members connected to a hydraulic cylinder and perpendicularly oriented with respect of the iron plates.

[0042] The force was quantified by means of a charge cell having a resolution of 11.02 lbs and a special gauge was used to evaluate t...

[0044] A prefabricated wall panel in accordance with the present invention having a size of 15.74″×19.68″×1.96″ and a metallic grid including two horizontal rods and two vertical rods each having a size of ½″×½″ forming one complete quadrangular cells, was submitted to a test for determining its charge capacity when applying an axial force.

[0045] The test was carried out by placing the wall panel over one of its longitudinal sides. The force was evenly applied over the total length of the panel by means of a horizontal elongated metallic member connected to a hydraulic cylinder.

[0046] The force was quantified by means of a charge cell having a resolution of 11.02 lbs and a special gauge was used to evaluate the vertical deformation of the panel. The force was applied until the panel failed thus obtaining a maximum endurance force of 8,126.23 lbs and a maximum vertical deformation of 0.095″

[0047] The following graphic show the values of force versus vertical deformation until half ...

Abstract

A low cost prefabricated wall panel comprised by an internal metallic grid structure incorporating a plurality of sandwiched cardboard strips, two cardboard sheet covers, a fire proof substance applied to both cardboard sheet covers and to the wall panel edges and means for linking other panels. The internal cardboard core acts as a sound and thermal insulator, which helps to lower the energy consumption used for cooling and heating inside the construction.

Description

A. FIELD OF THE INVENTION [0001] The present invention is related to prefabricated walls and more particularly to a prefabricated wall panel comprised by sandwiched cardboard supported by an iron structure. B. DESCRIPTION OF THE RELATED ART [0002] There are well known the prefabricated walls comprised by a plurality of superposed flat panels. [0003] Many of the panels forming the prefabricated walls are made of wood or a combination of other materials such as polyurethane, plastic, etc. for providing a number of desirable characteristics such as convenient sound and / or temperature insulation properties. Furthermore, a fire proof or water proof covering may be included in order to comply with local regulations. [0004] A space divider is disclosed in the U.S. Pat. No. 4,706,422 which comprises two perforated walls with two opposite edges inturned to mate to form cavities to hold acoustic bats therebetween and including intersecting stiffeners and means to hold a pull-over fabric cover...
