Definitions

  • Construction of walls is usually carried out directly in situ on the building floor or pavement where such walls are to be disposed. Therefore, a frame is provided with the reinforced concrete and the concrete mixture therein.
  • the invention has been developed with the purpose of providing a mould that allows making prefabricated walls without a necessity for building them in situ, with the consequent total costs and time savings.
  • the invention provides further advantages as it will be detailed hereinbelow.
  • the mould for making prefabricated walls of the present invention comprises a frame defining a cavity adapted to receive the concrete mass and the corresponding reinforced concrete.
  • said frame is provided with a horizontal flat bottom, end walls, side walls and means for collapsing said end and side walls allowing a quick and effective demoulding of the obtained wall.
  • This simple configuration is effective for making prefabricated walls without the need for them to be built at the building site with the consequent time and cost savings.
  • the horizontal bottom of the mould which may be made from a metal plate, allows obtaining fully straight walls without the necessity for a subsequent plastering thereof.
  • the means for collapsing the mould walls comprise shafts extending parallel thereto.
  • the ends of such shafts extend through a plate welded to said horizontal bottom and a plate welded to each wall of the frame.
  • the shafts of said means for collapsing the mould walls allow the wall to be collapsed, tilting them outwards into a demoulding position and closing them towards the bottom remaining perpendicular thereto in the moulding position.
  • the mould that is herein described is also provided with wall locking means for locking the walls relative to the bottom.
  • Said wall locking means comprise pins received within in holes formed in the plate welded to the mould bottom and to a plate welded to the walls thereof, respectively. These pins are intended to prevent the walls from being collapsed relative to the mould bottom.
  • the frame may optionally comprise a divider device fitted therein.
  • Said divider device allows forming walls having different size using the same mould.
  • the divider device configuration comprises two parallel bars transversely provided inside the frame. Each of such bars includes perpendicular hollow protrusions inside of which corresponding protrusions are slidingly lodged perpendicular to the other parallel bar.
  • the hollow protrusions have locking means for locking the relative position of both parallel bars.
  • the invention also provides the possibility to increase the height of the walls and, therefore the thickness of the obtained wall.
  • the side walls and the end walls of the mould of the present invention are properly provided with holes and protrusions for joining the walls above each other.
  • a mould for making prefabricated walls comprising a metal frame defining a cavity adapted to receive the concrete mass and the corresponding reinforced concrete.
  • the metal frame is provided with a horizontal plane bottom (1) including support legs (1a), two end walls (2, 3), two side walls (4, 5) and means (6) for collapsing said end walls (2, 3) and lateral walls (4, 5) to allow demoulding of the obtained wall (7).
  • the means (6) for collapsing the walls comprise a number of shafts (8) extending parallel to the walls (2, 3, 4, 5) of the mould.
  • the ends of each shaft (8) pass through a plate (9) welded to the above mentioned horizontal bottom (1) and a plate (10) welded to the wall (2, 3, 4, 5) of the mould frame.
  • the shafts (8) allow the walls (2, 3, 4, 5) to be collapsed outwards into the demoulding position (see fig. 1) and closing them towards the bottom (1), being arranged perpendicular thereto in the moulding position shown in fig. 2 of the drawings enclosed in the present specification.
  • the plates (9) are provided with a through hole (11).
  • the walls (2, 3, 4, 5) include a plate (12) also provided with a through hole (13) that, in the moulding position (see figs. 2 and 3), it is aligned with the through hole (11) of the plates (9), as it can be seen in fig. n° 3.
  • These elements form the locking means of the walls (2, 3, 4, 5) relative to the bottom (1), which further comprise pins (13a) housed into the above disclosed holes (11, 13) intended to prevent the walls (2, 3, 4, 5) from being collapsed relative to said bottom (1).
  • a divider device (14) which is fitted inside the mould.
  • Said divider device allows forming of walls (7a, 7b) having different size with the same mould.
  • the divider device (14) is composed of two parallel bars (15, 16) transversely provided inside the frame.
  • the bars (15, 16) extend in walls (17, 18) the height of which is substantially similar to that of the walls (2, 3, 4, 5) of the mould, that is to say, similar to the thickness of the wall (7a, 7b) that is to be obtained.
  • the bar (15) includes two hollow holes (19, 20) extending perpendicular to said bar (15) as shown in fig. 5. Said hollow holes (19, 20) are intended to slidingly house corresponding perpendicular protrusions (21, 22) in the bar (16).
  • the protrusions (19, 20, 21, 22) guide the relative position of the bars (15, 16) and locking means for ensuring such position are provided consisting of pins (23, 24) transversely housed therein precluding relative movement and consequently maintaining clearance between bars (15, 16).
  • Said bars (15, 16) are attached to the side walls (2, 3) of the mould by means of screws (25, 26) which are screw threaded into perpendicular extensions (27, 28) thereof.
  • cylindrical holes (29) formed in the walls (2, 3, 4, 5) are provided, said holes (29) being intended to house complementary protrusions from an upper wall (not shown) thus allowing joining of said walls above them.
