Abstract

The invention consists of a jointed outlining guide for ceiling structures, for bent or round panels or for any curved architectural structure to be covered with plaster-board or other similar materials. The outlining guide formed by a series of box-like, U-shaped sections (1) linked by pliable joints are made preferably from a metal sheet in which circular or semi-circular slots are cut in such position that, when the sheet is properly bent, links between one box-like section and the other are formed.

The side walls of the open box-like sections can be of the same height or of different heights and their edges can be either straight or turned inward.

Description

Structures covered in plaster-board or similar materials are being more and more commonly used. They let us achieve light structures in many different shapes, particularly arched, bent or round shapes.
The aim of the present patent for an industrial invention is the suggestion of a solution that rationalizes the modelling of a structure during the construction stage, that is, before the structure is covered with panels.
The proposed solution consists of the creation of a jointed guide which can easily be shaped to form the outline of the structure to be achieved.
The guide is essentially a U-shaped preferably metallic and zinc-coated outline formed by a series of open, box-like elements made by bending towards the inside some of the material of the base and of the side walls.
In this way joints are formed in the structures which allow the outline to be bent in all directions while maintaining the same structural continuity of a stiff guide.
The solving idea can be better understood by referring to the enclosed illustrations where this idea is shown in an indicative, not obliging realization. In table 1/6, fig. 1) shows the sheet, preferably metallic, already cut so that it can be bent; in fig. 2) the sheet is already bent longitudinally to form a single box which is U-shaped in cross-section.
In table 2/6, fig. 3) and 4) show the structure bent at the cut points and seen from both the back and the front.
In table 3/6, fig. 5) and 6) show the vertebra in different bending situations; some bendings are carried to extremes, until the breaking of the more stretched connection element; in figure 7) is shown a box-like element separated from the others.
In table 4/6, fig. 8) shows a structure shaped by using a series of vertebrae.
In table 5/6, fig. 9), 10) and 11) show the structure with fixing vanes to create, as an example, a stair-like structure.
In table 6/6, fig. 12), 13) and 14) suggest a way of fixing the box-like sections by having the upper edges of their sides bent in order to snap them in appropriately shaped supporting structures.
With reference to the figures the base of the flexible, vertebrate guide is a box-like, possibly a parallelepiped-shaped element without one of its bases.
The different box-like open elements are linked together by appendices connecting the smaller side faces of box-like elements 1).
A box-like element consists of a basic sheet, possibly a metallic one with circular and semicircular slots, regularly spaced, in places which, when bent, create the smaller side faces.
This is to obtain, throughout the whole structure, connections which can be easily modelled by hand. The sheet cut with slots 4) and 5) is longitudinally bent to create one box-like element as shown in fig. 2); afterwards the box-like element is longitudinally pressed, bending it where the slots previously cut are present.
This is to obtain a chain of box-like sections all linked by the smaller side faces as shown in figures 3) and 4).
The connection of the box-like sections allows the structure to be bent along two orthogonal axes which lay on the plane of the smaller side faces.
Taking advantage of the easy pliability of the guide, it is possible to shape it following the outlines of the structure to be created, by first fitting the upright elements 6) and afterwards placing the plaster-boards and connecting them to the smaller and eventually to the largest faces of the guide.
According to the preceding description there are clear advantages to the use of the proposed guide. It makes possible endless types of modelling in order to create an outline as a bearing element for the panels making the structure.
When the outline has been modelled, it is only necessary to connect the panels to the structure: the assembling is quick and no skilled workers are required.
An improvement to the structure for a broader application can be obtained by lengthening one of the larger sides to create the appendices 7) as shown in table 5/6 in fig. 9).
It is then possible, as seen in fig. 11), to connect several, suitably staggered, flexible outlines by fixing the appendices of one outline to the side of the adjacent one.
In this way, it is possible to create a stair structure as suggested in fig. 10).
A further improvement of the structure is shown in table 6/6 by using bent side edges 8) as seen in a front view in fig. 12) and in an axonometric view in fig. 13) and 14).
This modelling allows the locking of the structure into small girders, properly shaped to receive, through the slots, the box-like elements which can by this mean be holded where desired.
The above-said explained and illustrated guide is suggested to be an open parallellepiped, U-shaped transversal section guide, but it can be made in a different form. Anyway it is possible to make changes, both formal and structural, without going out of the field of application of the invention which is characterized by the following:

Claims

A load-bearing, jointed profile used as an outline and as a sustaining element for light structures and particularly for round or bent ones, e. g. made of plaster-board; this profile is characterized by open box-like U-shaped elements connected by the smaller side faces.
A load-bearing, jointed profile as in the previous claim and for the purpose of the same, characterized by the smaller sides as the joining faces which are weakened by the removal of some material and bent so that the boxlike elements can relatively rotate along two orthogonal axes.
A load-bearing, jointed profile as in the previous claim and for the purpose of the same, characterized by the fact that it can be obtained possibly by a metallic sheet with slots in the parts which, when bent, form the smaller side faces which act both as connecting and collapsible elements for rotation.
A load-bearing, jointed profile as in the previous claim and for the purpose of the same, characterized by the fact that plaster-board or similar panels are screwed or anyhow fixed to the side of the rib formed by the box-like sections, along the larger base and/or along the side-faces.
A load-bearing, jointed profile as in previous claim and for the purpose of the same, characterized by the possibility to present along one side of the box-like sections protruding elements to be used for clamping to other structures or to any other elements.
A load-bearing, jointed profile as in previous claim and for the purpose of the same, characterized by the fact that, in order to guarentee the fixing of the same, each box-like section presents bent side edges to be positioned in appropriate supporting girders.
