Definitions

  • the invention presented herewith is related to a modular formwork for the construction of walls and/or pillars in concrete.
  • Such structures constitute a variety of disadvantages which include their unwieldiness when putting them to use due to the notable weight of the elements of the structure and the modular accessories needed to assemble the same; the short life duration of the modular elements resulting from the use of wooden boards which, in spite of their being coated with impermeable resin, are subject to rotting; the increased costs and the high degree of complexity of the structure itself due, among other things, to the considerable number of accessories needed in putting it to use, above all in the case of corner wall construction or pillars.
  • Modular formworks are also known which, being made of plastic material, such as, for example, thermo-formed polymers, partially resolve the disadvantages shown by modular structures made of metal and wood.
  • the panels made of plastic material prove, in fact, to be particularly manageable and are scarcely subject to wear and tear.
  • the object of the invention presented here is to eliminate the above mentioned inconveniences in known types of modular formworks for the construction of walls, contriving to devise a modular formwork for the construction of walls and/or pillars which offers the advantage of being installable in a simple and rapid manner.
  • one of the aims of the invention presented here is to furnish a modular formwork for the construction of walls and/or pillars which is suitable for the construction of linear walls, T-shaped walls. L-shaped walls or pillars without the need for specially designed modular elements.
  • an aim of the present invention is to devise a modular formwork for the construction of walls and/or pillars which, exploiting the economy of scale, is feasible at competitive costs.
  • the formwork for the construction of walls and/or pillars which comprises a plurality of modular elements having a smooth surface on the inside of the formwork and on the outside a surface comprising reinforcing ribs, the modular elements being joined together by means of clamping devices, characterized in that the modular elements comprise complementary, lateral, segments for connecting one to another, capable of effecting the firm connection of two laterally adjoining elements by means of the clamping devices, and, moreover, in that the modular elements comprise protrusions above and below, enabling a firm connection of two elements adjoining vertically by means of clamping devices.
  • the connecting segments are designed in the form of openings, hooking pieces and segments inclined in relation to the base of the modular element or as complementary ribs.
  • the protrusions are shaped in the form of a "U”.
  • the formwork 10,110 comprises a plurality of elements 1,101 in plastic material, for example stamped and injection moulded, substantially in quadrilateral shape, which comprise on the outside, in relation to the formwork, reinforcing ribs 2,102 and which, on the inside of the formwork, constitute a smooth surface.
  • the said modular elements 1,101 comprise lateral segments 3,4,103,104,105 suitable for the firm connection between two elements 1.101 adjoining laterally.
  • the segments for the lateral connection are effected as complementary ribs 3, 4 between them, more protruding than the reinforcement ribs 2.
  • the ribs for the connection 3 are on one side where they form a plurality of square structures 5 in relief which, in turn, constitute an aperture 6 on their upper or lower facet respectively.
  • On the other side of the modular element 1 are ribs 4, inclined in relation to the base of the element 1 and terminated, at their most protruding point, by a panel section 7 parallel to the base of the element 1. Said ribs 4 protrude in such a manner that when two elements are placed laterally side by side, the panel sections 7 cover from above a part of the plurality of square structures 5 of the adjoining element 1.
  • the modular elements 1,101 comprise, on their upper and lower sides, protrusions 8,9,108,109 shaped in the form of a "U" substantially placed in the centre of the upper and lower sides.
  • the U-shaped protrusions 8,108 on the lower side comprise two, semi-circular indentations 11,111.
  • linking elements 20 for example flanged wing-nut-type clamps, which are generally made of fibre-glass reinforced plastic material.
  • These linking elements 20 comprise a body 21, which can be substantially assembled in the form of a "T", whereby the shaft of the "T” comprises a threaded section for the application of a flanged plastic wing-nut 22.
  • the short side of the "T" is hooked into one of the modular elements 1,101, while the flanged plastic wing-nut 22 is placed in a position where it can connect the suitably shaped opposite part of the other modular element 1,101, which is designed to receive and firmly arrest the flanged plastic wing-nut 22.
  • linking elements 20 are used to connect two horizontally adjoining modular elements 1 and one single fastener for the vertical connection of two adjoining modular elements 1.
  • the short side of the T-shaped body is inserted into the apertures 6 located on the upper and lower facets of two previously described square structures in relief 5, of a first modular element 1, while the flanged plastic wing-nut of the fastener 22 is placed between two corresponding panel sections 7 protruding further out from the complementary ribs 4 of the second modular element 1.
  • the particular configuration, especially of the lateral ribs 3,4 of the modular elements 1, permits the horizontal connection, as described above, which can be effected either in the case of a linear connection or in the case of an orthogonal, external or internal corner connection.
  • the square structure in relief 5 offers a support for the panel section 7 of the complementary ribs 4, irrespective of the manner in which the positioning is effected in one of the three possible reciprocal positions of two modular elements 1 (linear, orthogonal internal corner, orthogonal external corner).
  • the particular "T" configuration of the linking elements 20 enables them to be positioned easily and conveniently according to existing requirements in that the fastener can rotate in the apertures 6 around the rotation axis created by the short side of the T-shaped body.
  • the short side of the T-shaped body is carefully placed in the two semicircular indentations 11 of the lower U-shaped protrusions 8 of the first modular element to be connected, while the flanged plastic wing-nut of the fastener 22 is locked against the corresponding upper U-shaped protrusion 9 of the second modular element 1 to be connected.
  • the elements 101 of the second embodiment comprise one side of hooks 104 and complementary apertures 103 for the hooks 104 and, on the other side, are terminated by protruding sections 105 inclined at and angle of 45° in relation to the base of the element 101. Also, as already explained in regard to the first embodiment, on the upper and lower sides, U-shaped protrusions 108,109 are provided.
  • connection of two vertically adjoining modular elements 1 is effected in an identical manner to that for the first embodiment, the horizontal connection between the two elements 101 can be effected only for orthogonal, external corner connections, i.e. exclusively for the construction of pillars.
  • Such connections are effected from one side for securing the hooks 104 in the apertures 103, while on the other side, being analogous to the first embodiment by means of linking elements 20.
  • it is sufficient to rotate the first element 101 to an angle of 180° in relation to the other.
  • the assembly of the formwork in accordance with the described embodiment is effected as follows:
  • the initial assembly of a base 130 for the formwork may be carried out.
  • Examples of the respective base elements 131 are shown in Figures 9 and 10 for the second embodiment.
  • the base 130, thus constructed, is anchored to the ground by nails using the holes 132 provided for this purpose.
  • the elements 1,101 necessary to form the first layer of the formwork are successively connected to one another horizontally by linking elements 20.
  • the first layer of elements 1,101 are then fixed to the base 130 using the vertical connection procedure described above.
  • the elements 1,101 are connected together horizontally to form the successive layers which are then linked together vertically.
  • the total number of layers that will build up the finished formwork is variable and depends on the height of the wall and/or pillar to be constructed.
  • rods 140 In the case of constructing pillars by the second mode of constructing the formwork it is absolutely necessary to provide support by means of rods 140, anchored to the ground by nails. These rods 140 are fitted with a threaded metal ring 141 at their upper end, which ideally, by turning the ring, enables the adjustment of the length of the rod 140.
  • the screw-type linking elements can be substituted by any other means of fastening which enables the connection of two adjoining modular elements.
  • all of the details can be substituted by other elements and materials used, not to mention the dimensions, which can be freely determined in accordance with any requirements.
