Definitions

  • the invention relates to a structure for modular prefabricated forms according to the preamble of claim 1.
  • Structures of the this type are known, which are widely used in building, particularly for making forms or formworks, which are in turn used for making vertical and/or horizontal and/or inclined walls, such as floors, ceilings, slabs or the like, made of concrete.
  • These structures are typically made of a plurality of studs or joists, generally made of elongate box-like steel elements, which are disposed in parallel and/or crossed arrangement and at a predetermined distance from each other so to form a frame in which a plurality of adjacent panels are mounted in order to form a poured concrete retaining wall.
  • this panels or plates are coated with a waterproofing material such as layers of plastic materials and/or of paint.
  • a waterproofing material such as layers of plastic materials and/or of paint.
  • the core layer of the panels is made by wood or similar materials such as chipboards or the like.
  • the current state of the art comprises different kinds of combinations of panels, plates and stud or joists for building such walls.
  • Two different kind of structures can be mainly differentiated one for building vertical or essentially vertical walls and the other for building horizontal or essentially horizontal walls.
  • panels are known which are formed by plates mainly of wood or with a core layer or with a supporting layer of wood which are then mounted in the frames build by the parallel and crossed studs or joists.
  • the plates are laid with the side at the edges opposed to the side facing the concrete against the studs or joists. Gaps between adjacent panels are then filled or closed with pasty material such as silicone rubber or the like.
  • This operation is done by hand and has several drawbacks. First of all this operation is time consuming and thus costy. Furthermore the peripheral sides of the plates, i.e. the thickness sides are not optimally sealed against penetration of fluids and gases and particularly of water.
  • silicone rubber may not fill completely the gaps for their entire depths and has also a very high compressibility.
  • silicone rubber filled gap is subjected to the high pressure of the poured concrete then it is compressed below the surface of the panel facing the concrete so that grooves or channels are formed between the adjacent panels and the gaps which produce marks on the finished walls. Relating to this effect it has to be considered that a panel having 1350mm width and 2700 mm length and conceived for a pressure of about 60 kN/m 2, commonly requested by the building industry is subjected to a load of about 22 tons.
  • the L shaped filler strips are flush with the surface of the plywood plate with the wing of the L shape superimposing over the said front side of the frame in order to avoid gaps or the like.
  • the plywood plate is pressed in place inside the frame which is provided with the filler or adapter strips fixed to the frame sides. This has the drawback that during pressing of the panel inside the frame provided with the filler or adapter strips, the filler or adapter strip is compressed by the edges of the panel in a non controllable manner. So it is possible that due to the compression in a direction parallel to the surface of the panel or perpendicular to the peripheral edges of the panel the filler strips are also subject to a compression in a direction perpendicular to the surface of the plate or parallel to the peripheral edges.
  • the filler strip being of elastic and compressible material will be reduced in its thickness in a direction perpendicular to the surface of the plate and the surface of the panel adjacent to the concrete will present some steps due to the difference of the thickness of the plate and of the filler or adapter strip caused by the compression of the said strip.
  • the strip are only mechanically compressed against the edges of the plywood plate or panel and does not provide for a water tight connection between the peripheral edges of the plywood plate and the filler or adapter strip.
  • the exposure to penetration of water is increased considering the danger of the forming of steps between the strip and the plated edges due to compression of the said strips when the panel is forced in place in the frame provided with the said strips.
  • the strip will not cover the entire thickness of the panel edges forming the above mentioned step and leaving free to water penetration a part of the thickness of the edges of the panel or plate.
  • edge sealing is one of the most important topics of the panels to which the present invention refers which have a layered structure, both faces of the panel being layered with a water proof sheet of platic material or paint or the like as disclosed above.
  • a further drawback of the panel according to US 3,137,909 lies in the fact that the filler strips can only have a limited elastic compressibility and thus this strips can compensate only very narrow dimensional tolerances between the frame and the panel or plates. Indeed providing strips with a high compressibility would allow the compensation of higher dimensional tolerances between the frame and the plates or panels but on the other hand the strips would also be compressed by the fluid concrete thus forming grooves or depressions which result in marks in the finished walls.
  • the plate Due to penetration of water or increased exposure to humidity at the peripheral edges the plate can be subjected to swelling in thickness.
  • the risks in a material degradation and particularly in swelling are higher at the edges which can become thicker than the rest of the plate causing again irregular surfaces of the finished concrete walls.
  • material degradation at the edges can cause breaking off of pieces of the plate at the peripheral edges particularly when the panels has to be used again and mounted in a new frame thus preventing the panle or plate to be used again..
  • the mounting of the said known panels in the frames requests every time at least a control that this mounting has succeeded and that no step or gap has been formed between the plates the filler strips and the frames. If some of these defects is discovered an intervention by hand is necessary for manually filling gaps or eliminating steps with other materials such as silicone rubber. In any case a perfect protection or sealing of the plate peripheral edges from the penetration of water of humidity can only be achieved by providing a sealing with sealing materials as for example the above mentioned silicone rubber or other sealants. This further steps request many hour of work and have an high impact on the costs.
  • a further drawback which is common to all panels cited above suited for building vertical walls of forms for pured concrete consist in the fact that the peripheral edges of the panels are not protected against mechanical damaging when the said panels or plates are not mounted in the frames. This is also particularly important if one consider the particular use to which the panels or plates are destined.
  • the present invention has the object of improving a structure as described at the beginning in such a way that in combination with achieving a perfect adherence between panels and studs or joists, so as to obtain a substantially smooth concrete cast, anyway free of the conventional unaesthetic marks or impressions left by prior art structures or wherein such marks or impressions are considerably reduced also a perfect sealing of the panels at the edges is obtained in a simple and relatively non expensive way.
  • a further object of the present invention consist in the fact that without giving up the above mentioned object a balanced and symmetric fitting of the panel or plate in the frame is achieved which allows compensation of high tolerances relatively to the dimension and the shape of the frame and of the plate or the panel without incurring in the formation of marks in the finished concrete wall.
  • Still another object of the present invention is to allow mounting and securing the panels or the plates to the frame in a simple, rapid and inexpensive way.
  • the invention achieves the above purposes by providing a structure according to claim 1.
  • any kind of bonding is meant such as soldering or thermal adhesion or the like as typically occurs by bonding plastic materials.
  • the bonding of the abutting edges to the peripheral edges of the panels are such that a water sealing effect is obtained at the interface between the abutting edges and the peripheral edges of the panel.
  • the abutting edges are made of compressible material such as rubber or rubber like plastic material or any kind of plastic material which has compressible elastic behavior.
  • the abutting edges are formed by polyurethanes and particularly by polyurethanes obtained from the co-polymerization of polyols with iso-cyanates.
  • the said polyurethanes can be molded either by casting at low pressure or by high pressure injection in order to obtain the strips forming the abutting edges according to the present invention.
  • the polyurethanes can be also charged with inorganic charge materials.
  • the panel is a laminated panel having at least two layers, one of which is a cover layer of plastic material, included thermoplastic fibers, and the other is a supporting layer of other materials such as for example wood or the like.
  • the strips forming the abutting edges are bonded at least to the cover layer of the panel by means of chemical/physical bonding forming a water tight junction between the said cover layer of the panel and the strips forming the abutting edges.
  • the said trips forming the abutting edges may also be bonded to the peripheral edges of the supporting layer.
  • the supporting layer is of wood or the like a direct bonding can be obtained between the strips forming the abutting edges and the corresponding peripheral edge of the wooden supporting layer or and adhesive layer can be provided between the adhering faces of the strip forming the abutting edges and the peripheral edge of the panel.
  • the panel is made of at least one supporting layer made of at least one layer of wooden material and which supporting layer is covered on both of the opposing surfaces by a cover layer of plastic material bonded thereto, the strip of plastic material forming the abutting edges being bond to the peripheral edges of the panel by chemical/physical bonding with at least each one of the peripheral edges of the cover layers and/or also with the peripheral edge of the supporting layer.
  • the bonding of the strips forming the abutting edges of the panel are bonded with a water tight junction at least with the two cover layers of the panel.
  • the panel provided with the stepped abutting edges bonded thereto solves several of the drawbacks of the known panels.
  • the fact of providing the said abutting edges bonded to the panel protects the peripheral edges of the panels against ruptures and allow a very simple handling and mounting of the panels in the supporting frames.
  • the panels according to the present invention can be simply pressed inside a frame formed at least by two opposite studs or joists or by four stud or joists.
  • the strong bonding of the abutting edges to the panel plate provide for the fact that the abutting edges are always flush with the surface of the panel plate.
  • the junctions between the strips forming the abutting edges and the panel plate are water tight and any further manual work can be avoided.
  • the panels can be at least provisionally or also definitively retained in position within the frames by simply pressing them inside the frame due to the compression forces acting perpendicularly to the peripheral edges of the panel plate and generated by the compression of the elastic or compressible abutting edges.
  • the stepped abutting edges of the panel and the complementary stepped surfaces of the studs or joists of the frame against which the said stepped abutting edges of the panels abut has each one a surface which is essentially parallel or slightly inclined relatively to the surface of the panel and a surface which is essentially transversal or perpendicular to the surface of the panel.
  • At least the surface of the abutting edges which is essentially transversal or perpendicular to the surface of the panel or which is essentially parallel or slightly inclined relatively to the direction of pressing the panel in the frame has at least one or more continuous projection or lip which is compressed and deformed against the corresponding surface of the stepped studs or joists of the frame when the panel together with the abutting edges is pressed into the frame.
  • the stepped abutting edges are shaped in such a way that the external peripheral edges of the said abutting edges of adjacent panels adheres one to the other the surfaces of the said abutting edges parallel to the surface of the panel and oriented against the concrete, i.e. opposite to the frame being flush one with the other and flush with the corresponding surface of the panels.
  • the mechanical behavior of the strips forming the abutting edges satisfies every of the above functions of the said butting edges as disclosed above, namely the abutting edges allow the mounting of the panels in the frame by pressing simply the panels in the frame, ensures a water tight adhesion to the frame, the peripheral edges of the abutting edges of adjacent panels adhere one against the other without forming gaps, the said abutting edges provide for compensation of dimensional tolerances between the panels and the frame due to their construction or to thermal expansion or to expansion determined by swelling of the plates and the said abutting edges has sufficient dimensional stability not to be compressed by the concrete in a way that determines marks on the finished walls and also that the mechanical resistance of the abutting edges of the panels protects the peripheral edges of the panel from being mechanically damaged during handling.
  • the abutting edges are made in such a way as to show different compressibility in a direction perpendicular to the syrface of the panel and in a direction parallel to the surface of the panel.
  • the said different compressibility behavior is achieved by providing at least the surface of the abutting edges which is essentially transversal or perpendicular to the surface of the panel or which is essentially parallel or slightly inclined relatively to the direction of pressing the panel in the frame with at least one or more continuous projections or lips or with at least one row of discontinuous or dot or spot like separated and spaced apart projections or lips which are compressed and deformed against the corresponding surface of the stepped studs or joists of the frame when the panel together with the abutting edges is pressed into the frame itself.

  • the said projections or lips can be provided of the same material of the abutting edges of the panel and provide for a different compressibility in a direction parallel to the surface of the panel due to their shape and dimension.

  • each differently dimensioned projection element or lips has a different thickness in the direction of protrusion form the surface of the profiled element to which they have to be secured.
  • a preferred embodiment provides for projection elements or lips having a toothed securing pin which carries a projection head being made of compressible material, while holes are provided at predetermined positions on the profiled element in which the toothed securing pin can be removably engaged by elastic forcing the said securing pins in the said holes.

  • Each wall, formed by a number of adjacent panels externally covers the bearing frame elements.
  • the studs and joists or crossbars or any other elements of the bearing structure have the same construction on both opposite faces for abutment against the panels, i.e. the above described ridges 102, 102', 102". Therefore, the bearing structure elements, i.e.

  • the resilient or soft edges automatically provide, upon contact there between, an at least partial sealing action against weather conditions, such as water and wind, and are limited to a single junction line along the panel edges.

  • the edges fully cover the outer side of the bearing frame, which is generally made of a metal material and has a high thermal conductivity, the fact that the frame is fully externally covered by the panel edges allows to enhance thermal insulation of the structure, by simply forming a thermally insulating barrier between the bearing frame and the outside and/or inside environment. The effect is further enhanced when two wall shells are provided, an inner shell and an outer shell. Furthermore, when two shells are provided, the air gap formed by the two panel shells may be filled with intermediate thermally insulating panels, such as foam panels. Since the frame is of the prefabricated type, said intermediate thermally insulating panels may also have a predetermined size and shape, which is complementary and corresponding to the distance between elements such as the joists and the studs or the crossbars of the bearing frame.
