Abstract

The upper and lower limiting surfaces of the walls (1-4) lie in a common plane. At least sections of the front side wall (1) run inclinedly so that the lower edge (1a) of this side wall is set back in relation to the upper edge (1b). On the upper limiting surfaces of the two lateral side walls upwardly extending contact ridges (3',4') for the front side wall of a stone to be placed upon them are provided.Each ridge on at the rear end has a contact surface (3'',4''), which acts as stop for the lower edge of the front side wall of a stone placed upon it. The stop surfaces can be formed straight (parallel) to the front side wall or be polyhedral. In this latter case, a central surface can run straight and connecting to it can be two surfaces angled through 45 degrees

DESCRIPTION

  The present invention relates to a building element called "slope block", having a structure essentially of parallelepiped shape and having in particular four side walls which delimit a void crossing the block from top to bottom, the upper and lower delimitation faces. walls being

  located each time in a common plane.

  Such slope blocks are used for the erection of inclined or vertical slope walls by stacking the blocks on top of each other and filling them, during this operation, with soil for placement.

of slope vegetation.

  In order to keep the blocks to a certain extent aligned with each other in the stacked state, the most diverse devices are used, such as

  for example overlapping projections and grooves

  bars, bars, and so on. These means

  construction aids are not satisfactory

  tion for most of them or imply that the quality of the installation meets stringent requirements. The object of the present invention is to produce an embankment block, of the type indicated at the beginning, so that vertical or inclined walls - depending on the type of block - can be erected simply and without problems and that walls having angles can also to be built. The blocks must be able to be aligned simply at the desired position, without this requiring

special efforts.

  According to the invention, this re-

  result by an embankment block, of the type defined at the beginning, which

  is characterized in that at least segments of the pa-

  lateral king constituting the front or facing wall of the block are inclined, so that the lower edge of this wall is set back relative to its upper edge and that, on the delimiting faces

  upper sides of the two side walls located on the sides

  Tees are provided with projections directed upwards and forming stops for the facing wall of a block to be placed on these delimiting faces, projections whose stop faces, placed at the rear, are at a distance from the upper edge of the facing wall which

  is at least equal to the distance from which the edge in-

  lower of the facing wall is set back.

  Thanks to the realization of the block according to the invention-

  tion, with a facing wall inclined rearwards from top to bottom and with two abutment projections at the top,

  vertical or inclined walls can be erected

  particularly simple and the desired geometry of the

  wall can be adhered to without problems.

  Other features, advantages and modes

  of the invention will emerge more clearly-

  ment of the following description of several

  non-limiting examples of implementation, as well as the accompanying drawings, in which: - Figure 1 is a top view of a slope block for erecting inclined walls; - Figure 2 is a section along the line II-II of Figure 1; - Figure 3 is a front view of the block according to Figure 1; - Figure 4 is a rear view of the block according to Figure 1; - Figure 5 is a top view of a slope block for erecting vertical walls; - Figure 6 is a section along line VI-VI of Figure 5; and

  - Figures 7a and b are respective sections

  construction of an inclined wall and a vertical wall, constructed

  both of slope blocks according to the invention.

  The slope block shown in Figures 1 -

  4, which is concrete, washed concrete or a constituent material

  analogous, for example, has a general form pa-

  parallelepipedic and essentially comprises four pa-

  lateral kings 1, 2 and 3, 4, between which extends a void 5 which crosses the block right through, from top to bottom. Such blocks stacked on top of each other to

  form an inclined wall or a vertical wall (see figures

  gures 7a and b respectively), are filled with earth

  putting to plant vegetation.

  As best shown in Figure 2,

  the side wall 1 forming the front wall or barrier

  ment, is inclined, so that its lower edge is disposed recessed, of a dimension L, relative to the upper edge lb. An upper segment and a segment

  of the facing wall 1 can be essen-

  partially vertical. In the example shown, see the

  Figure 2, the upper segment and the front of the segment

  bottom of the facing wall 1 are sensitive-

  vertical. The segment between segments above

  vertical and lower can be flat or curved.

  In the example shown in Figure 2, the front of the

  median segment is curved and its rear face is flat.

  In the front part of the upper delimitation faces (upper faces) of the two side walls 3, 4 located on the sides, there is each time a

  3 'or 4' stop projection in the form of an augmenta-

  the height of the wall. Each of the stops 3 ', 4' has at its rear end a stop face 3 "or 4" which serves as a stop for the lower edge of the facing wall of a block to be placed on the upper faces

mentioned.

  The stop faces 3 ", 4" can be recti-

  lines (and extend parallel to the barrier wall

  ment) or be broken up and made up each of two or more

  vantage of facets. In the latter case, a central facet can be rectilinear and parallel to the facing wall and two facets inclined with respect to it, of 45 for example, can be connected to it on either side. Thanks to this conformation, the blocks superimposed in a corner area of a wall, can also be placed while being aligned precisely.

  The length 1 of the stop projection or the

  tance which separates its stop face 3 "or 4" from the front edge

  tal, i.e. from the upper edge lb of the wall of pa-

  rement 1, corresponds approximately to the double, in the embodiment shown in FIGS. 1 to 4, of the withdrawal L of the lower segment, more precisely of the lower edge

  the of the facing wall 1 with respect to its upper edge

  laughing lb. Thanks to this length 1 of the projections, walls

  can be erected very simply (see figure

gure 7a).

  The embodiment of the block represented on

  Figures 5 and 6, differs only from that shown

  tré by Figures 1 to 4 by the fact that the length 1 'of the abutment projections or the distance between the faces

  stop 3 ", 4" from the upper edge lb of the barrier wall

  ment 1, roughly corresponds to the shrinkage L of the segment in-

  lower or lower edge of this wall 1, which

  allows the simple erection of a vertical wall (see fig.

gure 7b).

  As already mentioned, Figures 7a and b show

  trent respectively an inclined wall and a vertical wall both constructed of slope blocks according to the invention, the difference between the blocks employed residing in the

  length of the stop projections 3 ', 4', which are relative-

  long for the inclined wall and of appreciable length-

  ment equal to the shrinkage L of the facing wall for the

vertical wall.

  In the bottom of the void 5 of each block, can be placed, as shown in Figure 7b, a retaining plate 6 whose shape essentially corresponds to the bottom section of the void and which is intended to retain the

  earth or other matter loaded into the block.
