EXTRUDED SHAPE INLAID INTO A CONCRETE MASS, FOR THE CONSTRUCTION OF BALCONY RAILINGS AND DIVIDING PANELS

Abstract

Profiled shape embedded in a concrete mass (20), to erect rails and dividing panels (25, 26).

It comprises a longitudinal shape formed by a bottom (1) and side walls (2, 3) defining a longitudinal cavity (4) with an inlet mouth at its upper edge, inside which cavity (4) seats and retains said panel (26).

Near the upper edge (18) of the longitudinal cavity (4) it is formed a tearable laminar sheet (16) monolithically attached to the internal surfaces (2a, 3a) of the sides extended between said opposite surfaces, the union of said tearable laminar sheet (16) being determined by longitudinal tearing lines (17) defining a reduction of the cross section of said laminar sheet.

The profile has alignment means (7, 8) according to a same longitudinal line and means of retention of its vertical stability (11, 12).

Each external lateral surface of each side of said shape has at least one lateral projection (9) defining the retaining means of the profile within the set concrete mass (20) and at the same time providing the vertical stability means.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THIS INSTANT INVENTION

[0031] For the purposes of exemplifying the preferred embodiments of the present invention, attached are the following drawings illustrating same, in support of the below given description thereof, being these embodiment interpreted as one of the many possible constructions of the invention, hence it is not appropriate to assign any limiting value thereto, including within the scope of protection of the invention the possible equivalent means to those illustrated, while being determined the scope of the present invention by the attached claims in the corresponding Claims chapter. Likewise, in these Figures, the same references identify equal and/or equivalent means.

[0032] The profiled shape shown in FIG. 1 is based on a known rectilinear and constant cross section shape, consisting in a bottom (1) and side walls (2, 3). Preferably this bottom and side walls are monolithic, product of the extrusion in a non-ferrous material through a matrix. Each side wall (2, 3) is preferably slightly divergent upwards from bottom (1), and each side presents respectively an inner surface (2a, 3a) and the opposite outer surfaces (2b, 3b).

[0033] In FIG. 3 it is observed this shape has a vertical axis X; coming back on FIG. 1, the profiled shape has at its upper end (18) an inlet mouth (4) which opens upwards allowing access from above to the internal cavity of the shape. At its upper end said shape presents on each side of its outer surface of the respective laterals (2b, 3b) longitudinal grooves (5).

[0034] According to this instant invention, distanced above said bottom (1) and parallel thereto is placed a monolithic and transversal partition (6) determinining between (6) and bottom (1) a longitudinal housing (7), within which it is possible to lodge a flat bar (8) (See FIG. 5), allowing the correct longitudinal alignment and continuity between adjacent sections of axially aligned similar shapes.

[0035] Laterally, at least one longitudinal rib (9) projects from the external lateral surfaces (2b, 3b) on each side of the shape. FIG. 3 shows that there may be more than one longitudinally emerging rib from each surface (2b, 3b), of which a number of them are short projection ribs (10) spaced along each side from the upper end downwards, while underneath them the aforementioned rib (9) is located, which has a greater projection extension, allowing retaining supporting feet (11, 12). These laterally projecting lateral feet have a limited width, for example with a range of 5 to 15 mm., and are placed spaced along said rib (9) as shown in FIGS. 1 and 4, and linked to said rib (9) by conventional means, such as a screw (13) or rivets, or any other means of reciprocal linking. The function of these support feet is twofold: on the one hand they allow to settle with their ends (15) on a plane (14) within the setting material and on the other hand they allow to correct the position of each successive profiled shape axially aligned within the same vertical plane X, while at the same time said feet (11, 12) provides anchoring means for the shape within the concrete mass, once set.

[0036] At the upper end, adjacent to the entrance mouth (4) is placed a tearable laminar sheet monolithically joined to the mutually facing internal faces of said cavity side walls and extended longitudinally between said opposite surfaces (2a, 3a) along the whole length of said shape. As seen in detail in the enlarged view provided in FIG. 2, this monolithic laminar sheet (16) preferably has in its cross section a uniform thickness, although nothing prevents it from having variable thickness, and has two longitudinal section reductions (17) defining longitudinal weakening or tearing lines. These section reductions (17) are arranged parallel and preferably at the root or junction of the laminar sheet (16) to the respective face (2a, 3a), but nothing prevents these tearing or weakening lines to be placed at some distance internally from the walls, and preferably, determining parallel lines.

[0037] FIG. 4 offers a perspective view showing the insertion of the shape of this instant invention into a settled concrete mass (20), with the tearable laminar sheet (16) already removed. Said grooves (5) at both sides of the shape are intended to receive the vertical portions of L shapes (19) with their horizontal wing portion sitting against the concrete mass (20) for a proper and neat completion. It is observed in this Figure that once the tearable laminar sheet (16) is removed, the inner cavity (4) is free of any obstruction or deposit of the settled material.

[0038] In this same FIG. 4 it is further observed that the support feet (12) are staggered pieces with successive steps (21), which can be easily sectioned or bent until the profile reaches the intended vertical plane alignment X overcoming any deviation from the horizontal plane of the base or plate (14) on which the profiled shape rests. In turn, this succession of steps ensure the immobility of the profiled shape within said concrete mass (20) once the material has set.

[0039] FIG. 5 shows in frontal elevation by way of example the complete cross section of an upward open socket of the invention, already embedded in the set mass (20) with plate (26) and generic handrail (25) installed in the upper edge of the plate. Said plate (26) is shown immobilized using traditional means such a wedge (22), opposed to the backrest (23) and the weather strip (24). It is further observed in this figure that plate (26) using the upward open socket of the invention remains fixed and vertical to the concrete mass (20) emerging from said slab or the like without any visible means of support for the observer.

[0040] The mode of use of the present invention involves obtaining a slab, wall or substantially flat area (14), on which is placed longitudinally aligned the several lengths (if any) of the profiled shape necessary according to the length of the balcony railing or room divider. Then, the succession of profiled shapes are aligned according to the same horizontal plane by the insertion of said flat slabs (8) inside the longitudinal housing (7). Then it follows the alignment according to the vertical axis X of each of said shapes, supported on (14) by its bottom (1) and supports (11, 12). Then the setting material (for example concrete) is poured until said setting material is substantially flush with the upper edge (18) of the shape. Once the concrete has set, the tear-off monolithic laminar sheet (16) is removed, leaving the cavity (4) free wherein said panel (26) is placed.
