Method of making metal panels for buildings

Abstract

A method of making a metal frame that will be used to make metal panels that will be used to fabricate modular metal buildings. Currently, the metal frames are manufactured through forming processes, however, the steps adopted end up generating greater difficulty in the conformation of the metal sheet, and, consequently, increase in the manufacturing time; as well as, they cannot achieve a higher degree of quality, which reduces the added value of the metal frame and can lead to greater difficulty of assembly, lower productivity and higher labor cost. The ideal method, comprises of modular plates (1) that are formed by galvanized sheet frames (2), which are manufactured by the method with 22 forming steps through a roll forming machine (7) with profiling rolls (9) with specific frames (10), and each step has a roll (9) and a set of support rollers (12) for each forming step.

Description

BACKGROUND

The invention is directed to a method of making metal panels for buildings.

The present invention is a method that enables a faster and more efficient way of fabricating the metal frames that are used to make metal panels.

Presently, there are several methods of making metal frames using industrial machines. In a typical method, a metal roll is fed into a machine, the metal fed into the machine if folded, and lastly the metal folded is cut to a required size by the machine.

Currently, the metal frames are manufactured through a forming process, however, the manufacturing steps currently adopted end up generating a greater difficulty in the conformation of the metal sheet, and consequently, an increase in the total processing time of the metal frame.

The metal frames used in making the metal panels need to be manufactured with precision, for the metal frames must be fitted together properly to ensure the structural integrity of the building. The proper fitting of the metal frames prevents problems that are related to the rigidity and thermo-acoustic insulation of the building.

Methods currently used in the industry do not achieve a superior metal frame that will maximize productivity in the field of building construction. Productivity is reduced when metal frames are not fabricated correctly.

The intention of the present invention is to provide a method of making a metal frame that will be used to make metal panels that will be used to fabricate modular metal buildings. The present invention provides a method of making metal frames that will reduce the manufacturing time and the costs associated with making the metal frames. The metal frames created are of a higher quality of production, for they are more standardized. The metal frames produced are standardized to fit together when connected, thereby increasing the structural integrity of buildings made using the metal panels that use the metal frames.

SUMMARY

The present invention is directed to a method of making a metal frame that will be used to make metal panels that will be used to fabricate modular metal buildings.

An object of the present invention is to provide a method of manufacturing metal frames that will reduce the cost of production.

Another object of the present invention is to provide a method of manufacturing metal frames that will be more standardized.

Yet another object of the present invention is to provide metal panels, that use the metal frames that are fabricated using the present method of making the metal frames, that will result in the building of stronger modular metal buildings.

Yet still another object of the present invention is to provide metal frames that will be easy to assemble due to their standardization.
