Description

PREFABRICATED CORNICE FOR BUILDING

  The present invention relates to a prefabricated building cornice, called to crown the entablature of a building facade for consolidation purposes and decoration and 51e if appropriate chaining, connection between the facade wall

and the roof of said building.

  Cornices of this kind are known which are

  killed by assemblies of different elements, for example elements made of ceramic material and elements made of cement or concrete. To build these known cornices, it is necessary to set up, on the site, its various constituent elements, or even to form them in situ by molding or the like,

  and assemble or fix them appropriately. These operations

  tions are tedious and, therefore, costly. By

  elsewhere, they require the employment of a special labor force

Lisée.

  The present invention aims to eliminate these inconveniences

  by creating a cornice whose implementation can be performed quickly and easily, without having to resort to specialists, said cornice before, moreover, lend itself to multiple applications, that is to say in particular to the introduction in all desired dimensions, of

  any desired decorative pattern and any type and

building management.

  This object is achieved, according to the invention, by a cornice which is remarkable in particular that it consists of at least one prefabricated element provided with at least one longitudinal cavity capable of receiving a filling or horizontal reinforcing means or said element defining a substantially planar base surface and a substantially planar upper surface parallel to said base surface, and a front surface provided with

appropriate, a decorative pattern.

  The cornice according to the invention is provided, according to an advantageous embodiment, with a recess formed in its base surface and defining an alignment projection on the

facade wall of the building.

  Advantageously, the horizontal filling of the cornice according to the invention is provided by reinforcing materials, such as stabilized sand, concrete or the like, introduced into

said longitudinal cavity.

  In a variant, the horizontal chaining of the cornice

  according to the invention is furthermore provided by means of reinforcing

  formed of longitudinal reinforcing bars, in particular of metal, embedded in the reinforcing material

supra.

  According to a particular embodiment of the invention,

  to ensure the continuity of the chaining, the cornice is

  to a complementary formwork element which makes it possible

  maintain an adequate connection between the different materials possibly used in the construction of the building concerned. In another embodiment, the cavity of the upper cornice is provided with a metal or plastic coating or other profile in accordance with this cavity which

  then acts as a gutter to collect and listen to

  rain and thaw water.

  In a particularly advantageous embodiment,

  the cornice according to the invention comprises two longitudinal cavities

  nales offset horizontally and vertically relative to each other. This arrangement makes it possible to use a single prefabricated cornice instead of two superposed cornices each having a single longitudinal cavity; this results in a significant saving of manpower and binding material (such as mortar) called & assembling the two

cornices superimposed.

  The present invention also relates to a building cornice according to the invention associated with at least one other cornice of similar type, which is superimposed on the first one.

  in such a way that the longitudinal cavities

  edges of said cornices are horizontally offset one

  compared to the other, while being parallel to each other.

  In the case of the use of the cornice according to the ivention in association with a cheneau, this cornice is preferably associated with at least one other cornice of similar type, which is superimposed on the first cornice in such a way that the respective longitudinal cavities of said cornices are offset horizontally relative to each other, while being parallel to each other. To connect two cornices according to the invention which extend perpendicularly to one another, it is advantageous to use two corner pieces having the same profile as said cornices and being each adjusted end-to-end to the associated cornice, these two corner pieces being assembled one to the other by a

bevel joint.

  In order to ensure satisfactory support and anchoring of the roof of the building concerned, the cornice is associated, according to one embodiment of the invention, with an intermediate part called assembled riser, with cement or the like, by its lower surface, on the upper surface of the cornice and, by its upper surface, on the surface

  bottom of the roof or surface of the tile.

  The invention will be described below in more detail, in particular with reference to the appended figures which represent, by way of illustration, but not limitation,

  several embodiments of the invention.

  Figure 1 shows, in perspective, a cornice according to the invention, which is provided by way of non-limiting example

  a decorative relief of the type called 'Genoese cornice'.

  Figure 2 shows in vertical cross section a set of cornices formed by two superimposed elemental cornices.

  Figure 3 shows, in perspective, a cost element

  called frage & be associated with a cornice according to the invention.

  Figure 4 is a vertical section illustrating a cornice according to the invention, interposed between a wall of facade

and the roof of a building.

  Figure 5 shows, in perspective, partially in section and partially cut away, a set of cornices according to the invention, reinforced by metal chaining bars and associated with a shuttering element also armed and forming with the cornice a right angle. FIG. 6 schematically shows, in vertical section, a set of two superposed cornices, the cavity of the upper cornice acting as a collecting gutter and

  evacuation of rainwater and / or thaw.

  FIG. 7 shows, in plan, two corner elements connecting two cornices placed on facade walls which

form between them a right angle.

  FIG. 8 represents, in perspective and partially in section, a cornice according to the invention, formed of a single

  and same piece, which has two super long longitudinal cavities

laid with horizontal offset.

  The cornice shown in FIG. 1 is formed of a single prefabricated piece and has a decorative face 1,

  a lower flat surface 2 provided with a longitudinal protrusion

  dinal 3 and an upper flat surface 7 parallel to the sup-

  lower face 2, and a longitudinal cavity 4. The decorative face 1 may have any desired pattern, either in plan or preferably in relief. FIG. 1 schematically shows the example of a so-called "Genoese cornice" motif, but could be any other motif such as among others: quarter round, cavet, astragalus, scotie, elegi, heel leave, bandeau, greek, doucine, chamfer, groove, etc. The longitudinal projection 3 serves to place the cornice on the wall of a building in a perfectly aligned manner, that is to say in such a way that the extreme edge of the decorative face 1, and the longitudinal cavity 4 are perfectly parallel to the median plane of the aforementioned wall. This projection can also serve as a drip. This ledge may be secured on the wall of the building with a binder cornice interposed between the bottom surface 2 of the cornice and the upper surface of the wall, while the longitudinal projection 3 is set up so as to marry. the upper front edge of said wall, as is apparent, for example,

  of Figure 2 where the front wall is designated by the reference

  however, that the above binder layer (or the like)

  is designated by reference 6.

  In the embodiment, according to FIG. 2, a cornice A according to the invention having a decorative surface 1A (cavet type) and a longitudinal cavity 4A is placed, via the binder layer 6, on the

  wall 5, and a second cornice B with a decorative surface

  13 (round quarter) is superimposed on the cornice

  in such a way that the longitudinal projection 3B of this

  cornice B follows the upper longitudinal edge of the cornice

  A. The junction between the two cornices A and B can be

  provided by another layer of binder or the like (not shown

  felt in the figure). As is apparent from the drawing, the two cornices are superimposed horizontally offset, the upper cornice B being the most protruding from the outer surface of the wall; the wall may be covered with a layer of plaster or the like, designated by 5a. In the case where the cornices are of a material other than ceramic, it may be necessary to treat them as is treated

wall (by plaster, or the like).

  The longitudinal cavity of the cornice according to the invention

  is likely to be filled or chained

  killed, for example, stabilized sand, concrete or the like. This is indicated in FIG. 4 which shows a single cornice A interposed between a front wall 5 of a building provided with a

  plaster 5a or the like and the roof T of this building. Cornish

  che A is provided with a filling or chaining placed - for example by casting - in the longitudinal cavity and constituted by stabilized sand, concrete or the like preferably armed. To ensure support and anchoring of the roof on the

  cornice, there is interposed between them a raised 9

  profiled binder which is secured on the cornice A with a layer of anchoring binder 10, while another layer of binder or the like 10a connects the top of the riser 9 to the extreme part concerned with the roof T.

  In order to obtain a satisfactory connection between the

  ridge of the cornice proper and other materials

  used in the building concerned, it may prove to be

  to provide a substantially profiled formwork element 11

  in U, as shown in Figure 3.

  In the embodiment shown in FIG. 5, two superimposed cornices A and B are used, a roof support riser 9 and, on a right-angled partition wall, with the facade wall which carries the assembly. The longitudinal cavity 4A of the lower cornice A is filled with a chaining material, such as concrete, in which are embedded metallic rebars 8a. Similarly, the formwork element 11 is lined with a chaining material lla similar to that of the cornice A, in which are also embedded metal rebar llb whose ends are

  intermeshed with those of the rods 8a, as shown in the figure.

  It will be noted that the metal frames 8 front and Ila split intertwine with reinforcements of posts in

wait llc.

  In order to fill the angles formed between two cornices perpendicular to one another or between a cornice and a formwork element such as 11 (FIG. 5), it is envisaged, according to the invention, to use two corner elements. connected by a bevel joint. Figure 7 shows a ledge C placed on a building wall and a cornice D forming a right angle with the cornice C. Each of the two cornices is extended by a corner piece 12a, 12b respectively, these corner pieces being joined one to the other bevel, as indicated in 12c. These parts 12a and 12b could constitute

only one room.

  In order to obtain an advantageous arrangement in which the longitudinal cavity of a cornice according to the invention acts as a gutter, there is provided an embodiment such as that shown in FIG. 6, in which the longitudinal cavity 4B of the cornice upper B two superimposed cornices A and B is placed substantially flush with the roof and coated with a trim 13 suitably profiled, of

  preferably formed of a suitable metallic or plastic material

  prayed. This lining extends to above the edge of the roof, on the one hand, and covers, on the other hand, the exposed upper surface of the cornice, as indicated in 13a and

13b, respectively.

  FIG. 8 shows an embodiment in which one and the same prefabricated cornice has two longitudinal cavities 4, 4, 4, which are parallel and offset with respect to each other in the horizontal and vertical direction. This embodiment allows a faster implementation and more

  practice of the aforementioned advantageous arrangement.

  It should be noted that the cornice according to the invention can also be prefabricated without decorative relief; she

  may have a surface and / or a special frontal housing

  made to receive colored decorations or reported in the form of moldings. For this type of decoration, we can use different materials, such as terracotta, sandstone, earthenware, glass paste, stainless steel, anodized aluminum, enamelled steel, ceramic, colored glass, enamelled glass, natural wood, plywood / decorated navy , concrete

decorated enamelled and the like.

  For the manufacture of the cornice according to the invention, it is possible to use, as starting material, materials such as terracotta, expanded clay, clay moss, cast or reinforced heavy concrete, agglomerated heavy concrete or concrete. lightweight such as cellular or cellular concrete, foaming concrete, pozzolan concrete, polystyrene concrete, glass bead concrete, vermiculite concrete, mineralized wood concrete and the like. Of course, the invention is not limited to the embodiments described and shown; many modifications and variations can be envisaged by those skilled in the art without departing from the spirit of the invention as

  as defined in the appended claims.
