Definitions

  • the present patent relates to equipment for constructing buildings and in particular concerns a new non-retrievable formwork for positioning concrete casting formwork assemblies for the construction of concrete vertical walls and pillars and for the construction of reinforced concrete girths or base course.
  • reinforcing rods are also provided protruding vertically from the concrete bed and connected to the horizontal reinforcing rods embedded in the concrete.
  • Said reinforcing rods used as reference points for the erection of walls and pillars can, however, move and tilt during casting of the concrete bed.
  • the concrete casting formwork assemblies for the construction of walls and/or pillars are appropriately arranged on said reinforced concrete bed.
  • reusable formwork assemblies consisting of flat elements which are removed after setting of the concrete and are reused for the construction of other walls or pillars.
  • Said formworks are substantially panels which are provided with a smooth formwork back surface and are made of sheet metal or wood.
  • Reusable modular formworks are also known consisting of elements made of thermoformed plastic, with more limited dimensions and weight.
  • Formworks are also known in which said smooth formwork back surface is not flat but cylindrical or consists of two flat L-shaped surfaces. Said formworks are conveniently used for the construction of concrete columns and pillars.
  • a reinforced concrete girth or base course is constructed, approximately 20 cm height, on which the brick walls are then erected.
  • Said girth will enclose the slab, constructed subsequently, where the water and gas pipes and electrical cables will be embedded in the concrete.
  • the waterproofing layer which has the function of preventing damp from rising up, which would then damage the plaster and masonry work of the building.
  • the subject of the present invention is a new non-retrievable formwork for positioning the concrete casting formwork assembly for the construction of concrete vertical walls and pillars and for the construction of reinforced concrete girths.
  • the main aim of the present invention is to act as a fixed guide support that can be connected to the bed for positioning the formworks for casting the concrete for the construction of pillars and walls in general.
  • a further important object of the present invention is to provide a barrier to prevent the rising up of damp at the base of walls and pillars, thus replacing the waterproof sheath.
  • a further important object of the present invention is to act as a non-retrievable formwork for the construction of reinforced concrete girths for brick walls.
  • An important advantage of the present invention lies in that it permits positioning and non-removable fixing of the elements on the concrete bed immediately after casting of the bed, so that the references for the construction of walls and pillars are accurately identified, without being moved.
  • the new non-retrievable formwork can comprise a channel element, with generically U-shaped vertical cross section and, if necessary, horizontal lateral wings at the base and/or a cup or collar element, with vertical walls forming a substantially parallelepiped or cylindrical space, with open bottom and horizontal lateral wings at the base.
  • Said channel element can be usefully employed for marking the position of the walls of a building, where each element, properly positioned adjacent to one or more further elements, can rest directly on the concrete bed that was previously cast and be fixed to it in a non-removable manner.
  • said cup or collar element is usefully employed for exact positioning of the pillars which will be cast subsequently, after arrangement of the formwork assembly, and can rest directly on the concrete bed and be fixed to it in a non-removable manner.
  • each of said elements will be fixed by application, for example, of nails driven into the widened edges or horizontal wings at the base of said elements.
  • the widened bottom of said channel element has the main function of preventing the rising up of damp from the bed below.
  • said channel element has horizontal wings at the base which extend on both sides outside the vertical walls with approximate width of at least 10 cm.
  • the vertical walls constituting the walls of the channel are at least 20 cm high, so as to permit casting of the concrete, for example for the construction of a girth of adequate height.
  • the reinforcing rods can be properly housed inside said channel.
  • Said vertical walls of the channel also act as a guide for perfect alignment of formworks of known type, between which the concrete will then be cast for the construction of high and low walls, lift shafts, partitions etc.
  • channel elements eliminates the need for waterproof sheaths to prevent rising damp, a function which, as said, is performed by the bottom and widened edges of the channel element.
  • one or both ends of each channel are shaped to allow the bottom, the horizontal wings at the base and the walls to partially overlap the bottom, the horizontal wings at the base and the walls of the adjacent channel.
  • said cup or collar element comprises horizontal wings at the base, suited to rest on and be fixed to the concrete bed, as previously described, at the points where the pillar will then be constructed.
  • said element which, as said, has an open bottom for passage of the reinforcing rods protruding from the concrete bed, comprises said lateral horizontal wings at the base into which the nails for fixing to the bed are driven.
  • the upper edge of the lateral vertical walls of the element can be indented so as to form one or more seats or corresponding lugs for precise matching with the strings or laser beams constituting the grid commonly used for location of the pillars.
  • Said elements are then fixed to the bed by means of nails or other fastening means and left permanently in situ, where they will be used as a support and guide for positioning the concrete casting formworks for subsequent construction of the pillars.
  • the new channel and cup elements made preferably of plastic, have a reduced thickness, in the order of a few millimetres, hence they are extremely lightweight and can furthermore be easily covered with plaster.
  • said elements will have adequate dimensions for constructing walls of any thickness required, for example 20 cm, 25 cm, 30 cm etc. and pillars with dimensions, for example, of 35 x 35 cm, 35 x 40, 40 x 40, etc.
  • Figures 1 and 2 show three-dimensional views of the two opposite ends (C1) and (C2) of a channel element (C).
  • Figure 3 shows a three-dimensional view of a cup element (B), while figure 4 shows a vertical section of the cup element (B).
  • Figure 5 shows a plan view of a cup element (B) acting as a guide for the positioning of modular concrete casting formworks (K), for example of the type made of thermoformed plastic, for construction of a square section pillar.
  • K modular concrete casting formworks
  • Figure 6 shows a plan view of two adjacent channel elements (C1) and (C2) acting as a guide and support for the positioning of formworks (J), for example of the type made of wood or metal sheet, between which concrete is cast for the construction of vertical walls.
  • C1 and C2 acting as a guide and support for the positioning of formworks (J), for example of the type made of wood or metal sheet, between which concrete is cast for the construction of vertical walls.
  • Figure 7 shows a three-dimensional view of an embodiment of a corner channel element (D), while figure 8 shows a three-dimensional view of an embodiment of a T-shaped channel element (T).
  • the new non-retrievable formwork can be:
  • Said horizontal wings (C5, B2) at the base of the channel element (C) and of said cup element (B) are suitable for allowing each of said elements to rest on and be fixed to the concrete bed (P), for example through the application of nails (F).
  • said horizontal wings (C5) at the base of said channel element (C) extend on both sides externally to the vertical walls (C3) and can, for example, be at least 10 cm wide.
  • Said vertical walls (C3), constituting the walls of the channel, are preferably at least 20 cm high, so as to permit casting of the concrete (L), for example for the construction of a girth of adequate height.
  • Said vertical walls (C3) will be parallel and spaced from each other, for example by 15 cm, 20 cm, 25 cm etc., for performing concrete casting of corresponding width.
  • said vertical walls (C3) of the channel also act as a guide for aligning reusable formworks (J), for example made of wood, metal or plastic, or non-retrievable formworks, for example made of polystyrene, between which the concrete will then be cast for the construction of high and low walls etc.
  • J reusable formworks
  • non-retrievable formworks for example made of polystyrene
  • the bottom (C9), at the level of at least one end (C2) of the channel element (C), can overlap the bottom (C8) at the end (C1) of the opposite channel element (C).
  • each of said overlapping parts of the bottom (C8) and (C9) can, for example, be half as thick as the remaining bottom (C4), so that, when said parts (C8) and (C9) are overlapped, the overall thickness is equal to the thickness of the bottom.
  • the vertical walls (C3) of at least one channel element (C) will comprise an end section (C6) lying on a plane substantially parallel to the plane on which the walls (C3) lie and parallel to and overlapping the ends (C7) of the vertical walls (C3) of the opposite channel element (C).
  • said end section (C6) must be recessed with respect to said vertical walls (C3), so that when the channel elements (C) are positioned adjacent to each other, as shown in figure 2 , the vertical walls (C3) of the two adjacent elements are externally aligned, without discontinuity.
  • the new non-retrievable formwork can be a corner channel element (D), constituted by at least one pair of parallel vertical walls (C10), each joined and square to the corresponding wall of at least one further pair of vertical parallel walls (C11).
  • One or both the ends (C1, C2) of said corner element (D) are shaped and configured in such a way as to permit overlapping with the corresponding ends (C2, C1) of the linear channel elements (C) described above.
  • the new non-retrievable formwork can be T-shaped (T), made up of at least one substantially rectilinear vertical wall (C12) and at least one pair of corner walls (C13), positioned so as to define a first U-shaped channel (C14) with axis substantially parallel to said rectilinear vertical wall (C12) and a further U-shaped channel (C15) with axis substantially square to said rectilinear vertical wall (C12).
  • the cup element (B) comprises one, two or more lateral horizontal wings (B2) at the base, suited to rest on and be fixed to the concrete bed (P), while the bottom (B4) is completely open to permit passage of the reinforcing rods (A) protruding vertically from the bed.
  • the upper edge of the lateral vertical walls (B1) of the element (B) comprises, for example at the centre, one or more indentations or lugs so as to define one or more seats (B3) for correct positioning of the element (B) along the planned axes, identified by means of strings or light beams commonly used for positioning pillars and walls.
  • the lateral walls (B1) also act as a guide and support for the positioning of formworks (K), both of the reusable type, for example made of wood, plastic or metal, and of the non-retrievable type, such as those made of polystyrene, between which the concrete is cast for the construction of pillars, in this example with square section.
