Definitions

  • the present invention relates to improvements to the devices enabling reserves to be made in concrete.
  • a full reserve is formed by a foreign body such as a block of polystyrene embedded in the concrete.
  • a hollow reserve is generally formed by a cylindrical cavity allowing, for example, the passage of an assembly rod.
  • frames are used, assembled to form a capacity border, resting on a flat surface, delimiting a volume in which the concrete is poured.
  • prismatic blocks are used, made of expanded polystyrene for example, having at the base of each of their lateral faces a tab making it possible to position the block either relative to a neighboring block, or relative to the edge of capacity.
  • the blocks which are simply joined by the ends of the aforementioned legs, can move and, secondly, because it is not possible to vary the distance between blocks or between blocks and borders.
  • the device of the invention overcomes these drawbacks and it is remarkable in that we use bracing elements which can partially fit into the ends of the legs of the blocks and join them together.
  • Each bracing element has, in section, the same shape as the leg and has at one end a shouldered portion of smaller section, capable of being engaged in a recess, of the same section, provided at the end of the legs of the block.
  • This element has at its other end, a recess identical to those provided on the legs, said recess can therefore receive the stepped part of another bracing element or the end of an assembly part whose section is identical to that of said shoulder part.
  • this device is particularly advantageous when it is a question of maintaining perpendicular to the plane of the slab to be poured a cylindrical spindle intended to produce a hollow reserve. This device is also advantageous when it comes to positioning threaded bushings.
  • a plate is used which is kept pinched as in the main application and having, at its upper part, a tongue on which the reservation pin is engaged.
  • 1 is a flat, horizontal surface, constituting the bottom of a mold delimited by rules 2, forming capacity borders, in which it is desired to pour concrete.
  • bottom 1 blocks 3 made, for example, of expanded polystyrene and having towards their base and on each of their lateral faces, tabs 4.
  • the wedging of the blocks with one another, or with respect to the rules can be carried out with the aid of bracing elements 5 each having, at one of their ends, a shouldered part 6, of smaller section, capable of being engaged in a recess 7, provided at the end of each of the legs 4.
  • Each element 5 has, at its other end, a recess 8 identical to those 7, allowing by means of an assembly part 9 which can be engaged by one of its ends in a recess 8 and by the another in one of the recesses 7 of a block 3, to connect said block or said element (for example: block 3a to element 5a in FIG. 1).
  • the recesses 7 and 8 open onto the bottom 1 which allows, in particular, the positioning of the blocks 3 by a movement perpendicular to said bottom.
  • the shouldered parts 6 affect, in a section made by a vertical plane perpendicular to the axis of the element, a semi-circular profile.
  • the recesses 7 and 8 have an identical profile as well as the parts 9.
  • the plate 11 has, on its lower edge 12, a semi-circular recess 13 whose section is identical to that of the part 6 of the elements 5 or that of the parts 9.
  • the plate 11 is held perpendicular to the bottom 1, pinched between the end of a tab 4 and that of an element 5, said plate overlapping, as the case may be, a part 6 or a Exhibit 9.
  • the pin 10 has, at its lower end, a slot 14 (FIG. 4) whose width is equal to the thickness of the plate 11.
  • the positioning of the pin 10, relative to the plate 11, is ensured by a notch 15, provided on the upper edge 16 of said plate.
  • the profile of the notch 15 is delimited by a rectilinear part, which is connected obliquely to the upper edge of the plate by its end situated towards the recess 13 and by a curvilinear part connecting the other end of said rectilinear part, and said upper edge of the plate.
  • the bottom of the slot 14 of the pin 10 is shaped so as to match the profile of the notch 15.
  • a ring 17, made of an elastically deformable material, which engages on the lower end 18 of the spindle 10, the positioning of said ring, relative to the plate 11, being provided by two notches 19 provided on the lower edge 12 of said plate.
  • edges 12 and 16 of the plate 11 are connected to the ends of the plate in two portions 20 and 21, cut according to arcs of a circle whose centers are coincident with that of the semi-circular recess 13, so as to allow the withdrawal of the plate 11 and of the spindle 10 by pushing on the said spindle, in the direction of the arrow F (FIG. 3).
  • the device of the invention also makes it possible to position a threaded sleeve C, of a known type, so that, after the setting of the concrete, the orifice of the sleeve is flush with one or the other of the faces of the slab.
  • the holding of the plate 22 is carried out in the same way as that described in connection with the plate 11.
  • the plate 22 is wound at one of its ends so as to form a collar 24, with a constricted opening, in which one engages force the C socket.
  • the support C is maintained by a tube 25, split longitudinally, the length of which is equal to the thickness of the slab to be produced and having, at its upper part, a collar 26, similar to that 24, for receiving the socket C.
  • the lower end of the tube 25 is engaged in the collar 24 of the plate 22.
  • auxiliary plate such as that 27. disposed perpendicularly to that 22, the assembly of the two plates being carried out by means of slots extending at mid-height.
  • a particular problem to be solved consists in making a reserve in the concrete in line with the joint plane of a tab 4 and an element 5 or, in line with the joint plane of two abutting elements 5 (Figure 9).
  • the plate 31 has a notch 32 in which the shoulder 6 of the end of the element 5 is housed.
  • the lower end of the pin 28 has a recess 33 so that said end has a tubular shape ( Figure 14).
  • a pin 34 is used, the lower end of which passes through a housing 35, placed upside down and the free edge 36 follows the outline of the legs 4 and of the elements 5 (right part of FIG. 9).
  • the assembly is removed by acting axially on the upper end of the spindle 34. This action has the effect of pushing back the plate 31, as described above, and the housing 35, whose sharp edges cut the material from which the tab 4 and the element 5 are made.
  • the housing 35 can be fixed by any means to the pin 34 but; these two parts can be independent and, in this case, the pin 34 has a shoulder part 37 which bears on the bottom of the housing 35.
