Definitions

  • the present invention concerns a constructive element, of the modular and prefabricated type, usable in the building trade to make walls, where the word wall shall include both flat or curved structures with a vertical development, and also horizontal structures, such as for example floors or floor slabs of buildings.
  • the panels of insulating material are disposed facing each other so as to define an interspace for a cast of concrete, and possibly so as to introduce a metal reinforcement. Between adjacent panels it is necessary to insert spacers, to maintain the panels distanced from each other and to define the overall thickness of the wall.
  • the spacers can consist of reinforcement rods, inserted through in the thickness of two facing panels and at the ends of which clamping terminals are attached.
  • Forms of embodiment are also known, for example described in documents AU-A-80741.75, US-A-5.553.430 and EP-A- 1.596.021, comprising two panels disposed facing each other with respective internal surfaces, in which corresponding spacers are inserted and retained. It is also known, for example from said document US-A-5.553.430, to use joining elements suitably configured to allow the reciprocal connection of two consecutive panels to define walls of a predetermined length.
  • the external surfaces of the panels must be covered with a layer of plaster, or layers of plasterboard to protect the panels from external agents or stresses, and to confer on the wall thus obtained a pleasant esthetic appearance.
  • One purpose of the present invention is to obtain a constructive element that is simple to assemble and simple to manage.
  • Another purpose of the present invention is to reduce the productional complexity of the constructive elements.
  • Another purpose of the present invention is to obtain a constructive element for making walls that allows a simple and rapid installation.
  • Another purpose of the present invention is to obtain a constructive element for making walls of buildings that reduces the finishing operations once it has been installed.
  • Another purpose of the present invention is to obtain a constructive element that is able to be assembled/dis-assembled so as to reduce the bulk involved in transport and storage.
  • the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
  • a constructive element for making walls comprises a plurality of first panels assembled with each other so as to be substantially aligned with each other, and a plurality of second panels assembled with each other so as to be substantially aligned with each other.
  • the first panels and the second panels are made of polymer material and are disposed facing each other, so as to define an interspace between the respective facing surfaces, or internal surfaces.
  • each of the internal surfaces of the first and second panels is provided with at least a first housing seating.
  • the first panels and the second panels have lateral or perimeter edges provided with second housing seatings.
  • the constructive element comprises spacers provided with at least a central core and terminals provided on the longitudinal edges of the central core.
  • the first housing seatings, the second housing seatings and the terminals are configured to allow the insertion of the terminals both in the first housing seatings, so as to maintain the first panels and the second panels distanced from each other and to define the interspace, and also alternatively so that each can be inserted into two of the second housing seatings of two of the first panels or two of the second panels assembled and aligned with respect to each other so that they can be connected.
  • the same spacer can be used both with the function of spacer between the first and second panels, and also with the function of reciprocal connection between assembled and aligned pairs of first panels or second panels.
  • This form of embodiment allows to reduce the productional complexity of the constructive element, and to simplify the warehouse management of the components necessary to make it.
  • the interspace between the first panels and the second panels can be filled with heat and/or sound insulating material or with a cast of reinforced concrete for subsequently making the walls with structural and heat/sound insulation characteristics established by the specifications.
  • the particular configuration described above of the spacers and panels allows to obtain a constructive element that can be installed quickly and simply in order to make walls of buildings.
  • the spacers in fact allow to assemble adjacent panels rapidly, defining both the thickness of the wall to be obtained and also the interspace that can possibly be filled by a concrete cast or with insulating material.
  • the panels are already in their final condition for use, and do not require other interventions, for example external covering with plaster.
  • the external surface of at least one of the panels is covered with a layer made of different material from that of the panel, and having a function of protecting the panels from external agents and also an enhancing function.
  • - fig. 1 is a section view of a constructive element according to the present invention.
  • - fig. 2 is an enlarged detail of fig. 1 ;
  • - fig. 3 is a first variant of fig. 1 ;
  • - fig. 4 is a second variant of fig. 1 ;

  • the first panel 1 1 and/or the second panel 12 can be made of composite material, for example of the type described in the patent application WO-A-201 1/117699 in the name of the present Applicant.
  • the material that the first panel 11 and the second panel 12 are made of allows to give the constructive element 10 characteristics of mechanical resistance, bearing capacity, resistance to aging and to knocks.
  • first panel 1 1, disposed during use toward the inside of the building is made of a transpirant material, for example of the type described in the application WO-A- 201 1/1 17699, and that the second panel 12, disposed toward the outside during use, is made with one of the polymer materials identified above.
  • This solution prevents any passage of humidity from the outside toward the inside, and a temporary retention and subsequent release of the humidity produced inside the building.
  • the first panel 11 comprises a single layer 1 1a with a substantially uniform thickness for the whole of its surface extension.
  • the second panel 12 instead comprises two layers 12a, 12b equidistanced from each other by spacer portions to define together a plurality of closed-section longitudinal cells 20.

  • the second segments 16b define with their edges said aperture 18 for the insertion of the spacers 17 and, together with the first segments 16a, undercuts to anchor the spacers 17.
  • Some forms of embodiment can provide that the housing seatings 16 (fig. 6) have a continuous development for the entire height of the first 11 and second panel 12, although it is not excluded that in other forms of embodiment the housing seatings 16 extend only for a part of the height.
  • Each spacer 17 (figs. 1-6) is defined by a section bar having a longitudinal development and a width substantially equal to the width of the interspace 13 between the first panel 1 1 and the second panel 12.
  • the spacers 17 can be made of polymer material such as polyvinyl chloride

  • the first segments 32 and the second segments 33 define together a C-shaped cross section and the central core 17a is connected in the center line of the intermediate side of the C.
  • the second segments 33 face toward the inside of the central core 17a, and are parallel thereto.
  • first segments 32, the second segments 33 and the central core 17a define, on one side and the other of the central core 17a, two attachment concavities 34 open toward the inside of the central core 17a.
