Definitions

  • the invention relates to prefabricated elements for the construction of walls and walls.
  • walls are used which are erected in the open air and fulfill various uses such as: retaining walls, storage walls, noise barriers along roadways or rail, etc.
  • the walls must have excellent stability and be capable of withstanding forces, in particular thrust.
  • T such large elements in the general shape of a "tee" (T) are both difficult to make in prefabrication, requiring complex molds, and difficult to handle, transport and set up on site.
  • the object of the invention is to solve these difficulties.
  • DOS document 2,456,915 it has already been proposed to constitute the wall element from two complementary elements, respectively a concrete base which can be placed on the ground and comprising on its upper face a cavity open upwards and a wall element comprising a foot which can engage and be posed by a movement of lowering then of tilting with ball joint over the base in final inclined locking position.
  • this solution does not provide, without other complementary means, a precise and constant laying plan from one element to the next and obliges to have the wall in an inclined position relative to the vertical.
  • the two complementary elements forming a wall element are both easy to manufacture, transport and handle, because they are both essentially in the form of a relatively flat long profile.
  • the installation on the site is particularly simple, since it suffices to position the base flat, and then introduce, in a vertical position, over the base, making the foot of the element penetrate. wall in the cavity of the base element, the wall element over the base.
  • the blocking of the assembly is done simply by locking the foot in the cavity by any suitable means such as wedge, filling with a junction material, etc.
  • a wall element 1 in accordance with the invention essentially comprises two complementary elements, namely a wall element 2 and a base element 3 serving it support sole.
  • These two elements 2, 3 each have a general shape of a relatively flat profile and are advantageously made of molded reinforced concrete, other materials which can however be used as a replacement as the case may be, the wall elements 2 can be produced for example by metallic alloy or in reinforced or unarmoured plastic profile as well as possibly the base 3.
  • the base element 3 has, in an intermediate part, for example around a third or a quarter of its length, a cavity 4 with a section flared upwards and which, in the 'Illustrated example, as it appears in particular clearly in Figures 4 and 5, has a general section substantially in the trunk of a pyramid with rectangular section. In other words, in the position of use of the base, with its sole 3a placed on the ground 5, the pyramid trunk is directed upside down.
  • the wall element 2 comprises, for its part, at its lower end, at least one foot 6 capable of being engaged with a certain clearance in the cavity 4, the foot having a section congruent with that of the cavity by presenting a taper angle more closed than that of the cavity. Also the foot at a height lower than the depth of the cavity which receives it (see figure 6).
  • the wall element 2 rests by a lower support face R formed in a step or step at the level of the foot 6 on an upper support face S, formed on the base 3 and adjoining the cavity 4.
  • the perfect positioning of the element 2 on the element 3 is ensured, in addition to the cooperation of the surfaces R and S by that of the face A of the cavity on which the face B comes to bear opposite the foot 6 of the element 2.
  • These faces can be formed with great precision during molding and therefore ensure perfect positioning relative geometry of the element 2 with respect to the element 3.
  • the assembly of the parts after erection of the wall element 2 and introduction of its foot 6 into the cavity 4, is ensured by the installation of a wedge 7 made of any suitable material which can be pressed into place to or to ground for example. Depending on the case, hardwood, metal or plastic shims will be used.
  • the assembly is perfect by filling any gaps between the cavity 4 and the base 6 by introducing a mortar of cement, sand or other suitable powder material.
  • the installation is particularly simple since it suffices, on site, to correctly position the desired base 3, for example by checking its horizontality if the wall 2 must be erected vertically. Then, by means of any handling device, such as for example a crane, the element 2 can be presented and put in place so that its foot 6 comes into place in the cavity 4.
  • the handling is facilitated by the provision in the upper part of the element 2 of one or more orifices such as 8 , which can be used, in addition, to receive transverse bars for the lateral locking of the successive wall elements of a wall, as constructed for example as illustrated in FIG. 7.
  • the element 2 is in place on the element 3, it suffices to block by inserting the shim 7.
  • the wall element 2 is advantageously profiled with stiffening ribs 9, making it possible to stiffen and lighten the construction.
  • the latter is advantageously produced as illustrated in more detail in FIGS. 4 and 5, in reinforced concrete with U-shaped reinforcements marked 10, 11, 12, mounted oblique, as it appears clearly in figure 5, and crossing with their openings which face each other by surrounding the cavity 4.
  • the cavity works correctly in compression thanks to the play of U-shaped reinforcements and the transfer of forces over the entire surface of the base.
  • This is for the rest made of reinforced concrete with simple reinforcements, suitably arranged as illustrated in particular in 13 and 14.
  • the base is suitably oriented so that its long part 3b is opposite to that which receives the thrust and the support polygon is adapted to the overturning torque which can be applied to the wall element.
  • the long branch 3b of the the armature 3 is directed outward relative to the slope 14.
  • the wall elements can have a width of 0.50 m, a height of 2.50 m at 3 m and the base can have an overall length of 1.50 m with the cavity 4 arranged at one third of the length.
  • the elements are relatively thin, their thickness not exceeding on average 30 cm.
  • the wall and base elements can be very easily made of reinforced concrete by means of simple molds.
  • the elements being flat, the setting of the concrete is fast.
  • the wall element composed of the wall element fixed on the base element is solid.
  • the applications can be multiple and we can cite in particular anti-noise walls, storage walls, embankment support walls, river retaining walls, civil engineering construction. They can also form the element of a lost formwork for example for foundations of important buildings.
  • the profile of the base allows in practice the use of the wall whatever the direction of the thrust exerted on it by the grounds or the stored materials which it will support.
