  MODULAR PREFABRICATED ELEMENT FOR BUILDING A WALL AND WALL

THUS OBTAINED

  The present invention relates to the technical field of construction and it relates, more specifically, to the means used to ensure the constitution of walls, walls or facings, from prefabricated construction elements mounted dry, of

superimposed.

  The field of application of the object of the invention relates to walls, walls or facing, which can be used to constitute constructions, waterproof or not, for protection, coating or retaining of structures or massifs

natural materials.

  To make walls of the above type, it is known to use prefabricated construction elements, of the modular type, generally made of reinforced concrete and intended to be placed on edge in bunk beds. The elements are kept in the assembled position by the nested mounting of the elements together and / or by their anchoring to the works or

  massive to be covered or supported.

  It has been found that such elements do not give complete satisfaction in terms of the stability of the construction that they constitute, insofar as there appear partial phenomena of sliding or relative displacement occurring between some of the construction elements. This drawback comes mainly from the very principle of assembling the elements together. In addition, such construction elements have a relatively large weight, due to their realization in reinforced concrete, which makes their transport, handling and

  uneasy handling and relatively high cost.

  Furthermore, the known prefabricated elements do not guarantee, over time, a perfect seal.

of the built wall.

  The present invention aims, precisely, to overcome the disadvantages set out above, by proposing prefabricated construction elements which can be associated with each other,

  simple and effective way, to form a rigid wall.

  The object of the invention also aims to provide prefabricated building elements capable of cooperating with

  means of assembly, of easy and quick implementation.

  The object of the invention is also to provide building elements which can be manufactured, transported, handled and

  handled easily and at a relatively low cost.

  The object of the invention also aims to provide prefabricated building elements for erecting a wall

  with an effective and lasting seal over time.

  To achieve the various objectives set out above, the modular prefabricated element for the erection of a wall is characterized in that it comprises: - two lateral faces extending in two substantially parallel planes, - a perimeter edge connecting the two faces and defining at least three sides, - at least one cut corner connecting two adjacent sides to delimit, with the corners of the other elements placed opposite, a passage of a rod of assembly means, - at least one projecting conformation rising from one of the faces and delimited by a flange extending back from the cut corner, so as to ensure, with the flanges of the elements placed facing each other, the centering of a head

  presented by Assembly means.

  Various other characteristics emerge from the

  description given below with reference to the accompanying drawings which

  show, by way of nonlimiting examples, forms of

  realization of the object of the invention.

  Fig. 6 is a plan view of the front face of a

  prefabricated building element according to the invention.

  Fig. 7 is a section taken along line VII-VII of

fig. 6.

  Fig. 8 is a partial perspective showing, more

  large scale, a characteristic of the object of the invention.

  Figs. 1 to 4 show, according to different views, a partial wall produced from modular prefabricated construction elements 1, according to the invention, placed on edge in bunk beds and fixed together securely, using means designed to ensuring the assembly of neighboring construction elements, by exerting a holding force on either side of the elements. Preferably, the assembly means are constituted

  by a cover 21 and a clamping ring 22.

  Each prefabricated element 1 constitutes a solid or hollow body, made of any suitable material. Advantageously, each prefabricated element constitutes a hollow body made of plastic, such as high density polyethylene and manufactured by the extrusion-blowing technique. Each element 1 constitutes a solid of any general polyhedral shape, of small thickness compared to the length of its smallest side and has, in plan, various polygonal shapes, such as

  triangular, parallelelogrammatic, pentagonal or octagonal.

  In the embodiment illustrated by the figures, the element

  has a rectangular shape in plan.

  As shown more particularly in Figs. 5 to 7, such an element 1 comprises two lateral faces 3, 4 said, respectively, front and rear, extending in two substantially parallel planes. The lateral faces 3, 4 are connected by a perimeter edge 5 defining, in the example illustrated,

four sides 6.

  The element 1 comprises at least one and, preferably, four cut corners 7 each arranged so as to connect two adjacent sides 6. Each cut corner 7, the function of which will be better understood in what follows, is inclined from one side towards the adjacent side, at a substantially equal obliquity, of

  preferably 45 degrees (fig. 6).

  The element 1 comprises, on one of its faces and, for example the front face 3, projecting conformations 8 rising from this face and set back from each corner 7. Each conformation 8 delimits a rim of centering 9 whose function will be better understood in the following. For example, the rim 9 extends parallel to the direction of the corner 7 formed in relation to it. Each conformation 8 is also delimited by an edge 10 inclined undercut. Preferably, the edge 10 is shaped to extend substantially in a direction in an arc centered on an axis X defined by the line of intersection of the planes containing two adjacent sides (fig. 6). The edge 10 has a medium radius RSet joins the rim 9 formed in relation to it,

  set back from the sides considered.

  As shown more precisely in fig. 8, the element 1 has, on its rear face 4, second protruding conformations 11 each rising from the face 4, near a cut corner 7. Each conformation 11 is delimited by a clamping ramp 12 inclined in draft, extending from one side 6 to the other, in an arcuate direction of

  circle centered on the X axis. The ramp 12 has a mean radius R'I.

  Preferably, the element 1 comprises, 'at least on each of its long sides, a centering pin 13 and a cavity 14 of section complementary to that of the pin. The cavity and the pawn

2628 1 28

  ensure precise centering and positioning during

  of the superimposed assembly of two elements.

  To constitute a wall (fig. 1 and 2) from elements described above, two elements 11 are placed in abutment by their short side facing each other, while a second pair of elements 12 is then mounted on the first pair . The elements 12 are centered and positioned by the mutual interlocking of the pins 13 in the receiving cavities 14. The four elements 1 thus positioned delimit, by their cut corner 7A placed opposite, a passage 15, of generally square shape, for a rod 16 carried by the cover 21 which is intended to be adapted on the face

before 3 of the elements.

  The cover 21 includes a head 17 designed to cooperate with the four centering flanges 9A placed opposite. In the preferred embodiment, the four flanges 9 delimit A square-shaped housing receiving a head 17 of

complementary (fig. 1 and 3).

  The cover 21 also includes an inclined edge 18 in undercut, intended to cooperate with the four inclined edges 10A placed opposite. To this end, the border 18 has a section and a shape complementary to those of the edges and constitutes an inclined annular border of average radius Ri which is, advantageously, substantially smaller than the radius RS

edges 10.

  The rod 16 of the cover has a threaded end part 19 which protrudes from the passage 15 when the cover is pressed against the edges 10. The threaded part of the rod is intended to cooperate with a thread 20 formed in the ring.

tightening 22.

  As shown more precisely in FIG. 3, the ring 22 includes a clamping counter-ramp 21 inclined in an undercut, annular and of medium radius R'i, so as to

  cooperate with the four ramps 12A placed opposite.

  Advantageously, the radius R '. of the counter-ramp 21 is substantially less than the radius R'S of the ramp 12, so that the substantially less than the radius R's of the ramp 12, so that the

  tightening of the ring 22 ensures a relative approximation of the four elements according to the arrows f, making it possible to obtain an efficient assembly of the elements between them (fig. 2). To authorize such a relative approximation, it appears necessary, on the one hand, to respect the conditions on the values stated above of the RS and R'S departments, compared to the R. and R 'departments. and, on the other hand, if i provide sufficient clearance between the flanges 9 and the head

  17, as well as between the rod 16 and the passage 15.

  Preferably, the radii RS and R'S of the conformations are substantially identical, so as to obtain an effort of

  equal clamping on each side of the elements.

  It should be noted that, to facilitate tightening of the ring 22, the latter comprises means 22, of all known types, for driving in rotation. In addition, the cover rod 22 is preferably provided with a reinforcement square 23 inclined in the direction of the threaded end part. To allow the housing of the square, each element 1 has a tilted pan 24

  from each corner 7 towards the front face 3.

  After the assembly of the first four elements, one proceeds to the mfse in place, successively, of a pair of elements placed side by side and / or superimposed, so as to erect

  a wall in relation to the desired dimensions.

  Of course, the wall can be fixed or not, at the beginning of its erection, on a sole, depending on the application

aimed.

  In an application to support a mass of natural materials, each element 1 has, on its rear face, a strip 25 ensuring the fixing of a known anchoring grid

in itself.

  It should be noted that the extreme elements constituting the lateral, lower and / or upper edges of the wall, can be produced from half or quarter elements for the corner elements, in order to provide continuous straight edges capable of to be capped by finishing rods of cross section

in "U".

  In the case of an impermeable wall, each element 1 has a groove 26 for adapting a perimeter seal 27. The groove 26 is formed in the sides 6 and in the front face 3 of one side 6 at its adjacent side, between each corner 7 and the corresponding flange 9 (fig. 6). When tightening the ring 22, each seal 27 is deformed, on the one hand, by the transverse surface of the head 17 (fig. 3) and, on the other hand, by the neighboring seals in mutual support at the sides , due to the approximation effect obtained (fig. 4). he can

  thus be obtained a perfectly sealed wall.

  In a preferred embodiment, a recess 28, concentric with the passage 15, surrounds each clamping ramp 12 and / or inclined edge 10, so as to allow the embedding of the ring 22 and / or of the cover 21 In the preferred embodiment of the elements in the form of a hollow body, each face of the elements comprises stiffening means constituted, for example, by an inclined edge delimiting a cell 31 with closed bottom and by at least one hollow conformation 32 practiced facing each other to have a mutual bearing surface (fig. 7). In this embodiment, each face can present, from

  sides, a peripheral chamfer 33.

  The invention is not limited to the examples described and shown, since various modifications can be made to it

without going beyond its framework.
