Description

PREFABRICATED STRUCTURAL ELEMENT FOR CONSTRUCTING BUILDING STRUCTURES, AND BUILDING STRUCTURE OBTAINABLE THEREWITH
The present invention relates to a prefabricated structural element for constructing building structures and a building structure obtainable therewith.
It is known that traditional dwellings, i.e. dwellings built using common building materials of the type of reinforced concrete and bricks, suffer considerable drawbacks.
Among the drawbacks of most importance are long construction times, complex execution techniques, the high cost of the raw materials used, reduced resistance to earthquakes, low heat insulation, and the high cost of construction and purchase.
In order to overcome these drawbacks, construction systems for building structures have been devised in which the walls are substantially constituted by panels of expanded polystyrene which are coupled at their main faces to respective metallic nets which are covered with cement plaster. These construction systems involve the provision, during construction, of stiffening structures which are interposed between adjacent panels.
For example in the solution in WO2010/260857 by the same Applicant, each panel is bordered by a series of metallic profiled members with a U-shaped cross- section, so as to accommodate each side of the panel between the mutually opposite wings of a corresponding profiled member. In order to join two panels which are side by side or superimposed, for example, two metallic profiled members are positioned with the corresponding cores juxtaposed and the wings turned on opposite sides toward the respective panels, and they are mutually connected by way of welding directly during construction. Construction is then completed by overlaying the metallic nets on both faces of the panels, and on these nets a layer of cement plaster is then applied. The mutually opposite metallic nets of each panel are connected to each other by way of elements for connection which are inserted to pass through the panel proper, and the various nets have the end flaps overlapped and are welded together so as to define a structure for containing each volume of the building, both internal and external.
However, this solution also can be improved from the point of view of simplicity of construction, by facilitating and speeding up the installation operations and avoiding performing soldering operations directly on the site, which lengthen the construction times, in addition to being difficult and hazardous for the workers and potentially damaging to the polystyrene panels.
Furthermore, the conventional solution described above can be further optimized from the point of view of structural resistance to external forces, reduction of consumption of materials, and thermal insulation.
Last but not least, according to the system of construction described above, floors and roofs are provided according to traditional methods and are then covered with sheets of polystyrene and associated metallic nets, and are then plastered.
The aim of the present invention is to eliminate the above mentioned drawbacks in the background art by providing a prefabricated structural element for constructing building structures which makes it possible to accelerate and facilitate the installation of such structures and to avoid the need to carry out welding operations directly on the site, so as to reduce the risks for the workers and for the materials in use.
Within this aim, an object of the present invention is to enable the construction of a building structure which has optimal characteristics of resistance to external forces, such as those resulting from atmospheric agents or earthquakes, and of thermal insulation, preventing "thermal bridge" effects between the inside and the outside. Another object of the present invention is to enable the construction of a building structure that is homogeneous in all its structural parts (vertical walls, floors, roof).
Another object of the present invention is to reduce the consumption of the materials used and as a consequence the costs of construction and of purchasing building structures.
Another object of the present invention is to provide a simple structure that is easy and practical to implement, safe in use and effective in operation, and low cost.
This aim and these and other objects are achieved by the present prefabricated structural element for constructing building structures, characterized in that it comprises two profiled members, each having a respective core, which are mutually spaced apart and rigidly connected by way of a plurality of connector elements arranged transversely to their longitudinal extension, a filler material being accommodatable between the cores of the profiled members.
This aim and these objects are also achieved by a building structure as defined in claim 16.

With reference to the figures, the reference numerals la, lb, lc generally designate a prefabricated structural element for constructing building structures and the reference numeral 100 designates a building structure obtainable by way of using the structural elements according to the invention.
Advantageously the structural element according to the invention can be assembled at a production site and supplied to the building site ready for installation.
The structural element la, lb, lc comprises two profiled members 2, 3 each of which is provided with a corresponding core 2a, 3a, which are arranged mutually spaced apart and are rigidly connected by way of a plurality of connector elements 4 which are arranged transversely to the longitudinal extension of said profiled members. Between the cores 2a, 3a of the profiled members 2, 3 a filler material can be accommodated, of differing nature according to the conditions of use.
The profiled members 2, 3 and the connector elements 4 are made of metallic material, preferably of the type of steel.
For example, each connector element 4 can be constituted by a stem, the opposite ends of which are threaded and have a reduced cross-section with respect to the central portion. Each end of the connector element 4 is inserted so as to pass through a corresponding hole 10 defined on one of the profiled members 2, 3 and is connected thereto by way of a threaded contrast nut, not shown.
However, alternative embodiments of the connector elements 4 are not ruled out.
Each profiled member 2, 3 is provided with at least one respective first wing 2b, 3b which is arranged adjacent to the corresponding core 2a, 3a and transversely thereto.
Preferably, each profiled member 2, 3 is provided with a pair of first wings 2b, 3b which are arranged at the opposite ends of the corresponding core 2a, 3a and transversely thereto.
If the first wings 2b, 3b of a profiled member 2, 3 are turned on the same side of the corresponding core 2a, 3a then an intrados 11 is defined in the cross-section of that profiled member, in which an insert 113 made of thermally insulating material, or the side of a panel P made of thermally insulating material of the type of polystyrene, according to the conditions of use, is accommodatable.
In a possible version, the structural element la constitutes a pillar (Figures 1-6), i.e. a supporting element intended to be installed vertically in the connecting region between two or more vertical walls which are defined by respective panels P.
In this case the first wings 2a, 3a of each profiled member 2, 3 are turned on the same side of the corresponding core 2a, 3a so that a corresponding insert 113 or the side of a panel P can be accommodated in the intrados 11 of each profiled member.
Preferably the first wings 2b, 3b are perpendicular to the corresponding core 2a, 3 a, defining a U-shaped cross-section.
Furthermore, the pillar la has a post 5 of thermally insulating material, of the type of polystyrene, which is interposed between the cores 2a, 3a and in which the connector elements 4 are inserted so as to pass through.
Preferably the connector elements 4 are distributed in an offset arrangement along the longitudinal extension of the profiled members 2, 3, i.e. in a zigzag arrangement.
Furthermore, the pillar la has a pair of end plates 6 for connection by¬ way of threaded elements to the foundation plane or between superimposed levels.
In this version (Figures 5-6) the pillar la acts as a continuity element between two consecutive vertical panels P, with no transverse walls being provided (Figure 6a).
Moreover, the profiled members 2, 3 can each have at least one second wing 2c, 3c which is consecutive to a respective first wing 2b, 3b and is arranged transversely thereto on the opposite side of the corresponding core 2a, 3a, so that the edge of a further panel P is accommodatable between the second wings 2c, 3c.
Preferably the second wings 2c, 3c are perpendicular to the first wings 2b, 3b and therefore they extend parallel to the corresponding core 2a, 3a.
In this case (Figures 3-4), the pillar la is adapted to be arranged in a corner in the connecting region of two or three vertical walls.
Figure 4a shows the use of the pillar la provided with second wings 2c, 3c for the connection of two vertical and mutually perpendicular panels P, one of which is arranged with a corresponding edge between the second wings and the other with a corresponding edge at the intrados 11 of the panel P. The intrados of the profiled member 3 can be filled with an insert 113.
Figure 4b shows the use of the pillar la provided with second wings 2c, 3c for the connection of three vertical panels P arranged in a T-shape, one of which is accommodated with a corresponding edge between the second wings 2c, 3c and the other two in the intradoses 11 of the profiled members 2, 3.
Again, each profiled member 2, 3 can have a pair of second wings 2c, 3c, of which each one is consecutive to a respective first wing 2b, 3b and is arranged transversely thereto on the opposite side of the corresponding core 2a, 3 a. The edge of a respective panel P is accommodatable between each pair of mutually opposite second wings 2c, 3c.
In this case (Figures 1-2) the pillar la makes it possible to connect up to four panels P arranged in a cross-shape.
Figure 2 A shows the use of the pillar la provided with two pairs of second wings 2c, 3c to connect two consecutive panels P and the intradoses 11 are engaged by corresponding inserts 113. Alternatively, one or both of the intradoses could accommodate the respective edge of the panel P.
In a variation (Figures 7-8), the structural element lb constitutes a bond beam, i.e. a supporting element intended to be installed horizontally to connect the superimposed levels of the building structure 100.
In this version both of the first wings 2b, 3b of each profiled member 2, 3 are turned on the same side of the corresponding core 2a, 3a so as to define respective intradoses 11, and a concrete casting G made during construction is accommodatable between the cores 2a, 3a.
Figure 14 shows a bond beam lb for the connection of vertical walls of superimposed levels of the building structure, while Figure 15 shows a bond beam lb for connecting a vertical wall to the roof of the structure proper.
For the connection of vertical walls of superimposed levels (Figures 7, 8, 14), advantageously, one of the profiled members 2 has a third wing 2d which is consecutive to a respective first wing 2b and is arranged transversely thereto on the opposite side of the corresponding core 2a.
In use the third wing 2d is arranged in an upward region on the outer side of the building and acts as a shoulder to contain the concrete casting to provide the upper screed of the floor.
Preferably the third wing 2d extends perpendicularly with respect to the adjacent first wing 2b, 3b and, therefore, parallel to the core 2a.
Furthermore, the elements for providing the floor are accommodated in the intrados 11 of the profiled member 3 that faces inwardly into the building, as will be explained below, while an insert 111 made of thermally insulating material, of the type of polystyrene (Figure 14), can be accommodated in the intrados 11 of the profiled member 2 that faces outwardly from the building.
Preferably the connector elements 4 are distributed in aligned pairs transversely to the direction of longitudinal extension of the profiled members 2, 3.
In a further version (Figures 9-11) the structural element lc constitutes a floor beam and is intended to be laid horizontally or inclined.
Based on the installation point, the profiled members 2, 3 can have one or two first wings 2b, 3b each.
Figure 16, for example, shows a special case of a beam lc for connecting the inclined pitches of the roof of the building in which each profiled member 2, 3 has a single first wing 2b, 3b which is inclined with respect to the corresponding core 2a, 3a. The edge of a corresponding panel P is arranged to rest on each first wing 2b, 3b.
More generally, the beam lc has one of the profiled members 2 with both of the first wings 2b turned on the same side of the core 2a so as to define a U-shaped cross-section with corresponding intrados 11, and the other profiled member 3 with the first wings 3b arranged on opposite sides of the core 3a so as to define a Z-shaped cross-section.
A joist 7 is accommodated between the cores 2a, 3a and is made of thermally insulating material, of the type of polystyrene, in which the connector elements 4 are inserted so as to pass through.
Preferably the connector elements 4 are distributed in aligned pairs transversely to the direction of longitudinal extension of the profiled members 2, 3.
Furthermore, an angular plate 8 is associated with each end of the profiled members 2, 3 for connection to bond beams lb or other end elements 114.
When used to provide a floor, the beams lc are arranged spaced apart and are interspersed by panels P. The particular Z-shaped cross-section of the profiled member 3 enables the insertion of the panels P between two consecutive beams 1 c.
The ends of the beams lc and of the panels P are accommodated in the intrados 11 of the profiled member 3 which faces inwardly into the building of the bond beam lb.
Figure 11 shows the use of beams lc interposed between a bond beam lb and an end element 114 in order to provide the supporting structure of a cantilevered floor.
By way of using structural elements la, lb, lc it is possible to provide buildings 100 in which vertical walls 101 , floor 102 and roofs 103 are obtained by way of the alternating juxtaposition of the elements and of panels P, the whole being covered by metallic nets 104 and covered by grout 105 both on the inner side, and on the outer side, according to a conventional method of working.
Obviously the plan and the number of levels of the building structure 100 can be varied according to requirements.
Figure 11 shows the cross-section of a possible building structure 100 obtainable according to the invention with two superimposed levels.
Advantageously a plurality of bars 106 is provided for anchoring the vertical walls 101 of the first level to the foundation plane F, which protrude from that plane at both of the main faces of the panels P and are connected to the nets 104 (Figures 13, 17, 18).
Furthermore, there are also bars 107 (Figures 14, 26) for connecting the vertical walls 101 of superimposed levels, which are inserted so as to pass through the panels P of the separation floor 102 at the internal main face of the panels P which make up the walls 101 and are connected to the nets 104. In this manner the rigidity of the structure 100 is increased and made uniform on the perimeter, instead of being concentrated at the pillars la.
In order to further optimize the strength of the building structure 100 at the bond beams lb, stiffening bars 108 are arranged resting on the connector elements 4, preferably four arranged in superimposed pairs for each bond beam lb, which constitute a reinforcement for the concrete casting subsequently carried out in order to provide the floor 103 (Figures 14, 15, 27).
Furthermore, there are contoured plates 109 for connecting the nets 104 to the profiled members 2, 3. The plates 109 have a recess for accommodating a metallic wire of the nets 104 and one or two side bands for connection to the profiled members 2, 3 by way of threaded connection elements, not shown.
In order to provide a building structure 100, first of all the vertical walls 101 of the first level are installed. To this end the anchoring bars 106 are arranged, directly in the foundation plane F, along the perimeter of the structure and the pillars la are mounted, by fixing the corresponding lower end plates 6 to the foundation plane F with threaded elements, not shown (Figure 17). Subsequently (Figure 18) the panels P are positioned between the pillars la. The openings, such as doors and windows, are framed with suitable conventional profiles 110.
Above the walls 101 a perimetric frame is provided by juxtaposing a plurality of bond beams lb, which are connected to the pillars la at the corresponding upper end plates 6 with threaded connection elements (Figure 19). The first wings 2b, 3b which are arranged below the bond beams la rest on the upper edge of the panels P of the first level and on the end plates 6 to which they are connected. Above the bond beams lb, plates 115 are arranged, above the lower end plates 6 of the pillars la of the second level.
An insert 111 made of thermally insulating material, of the type of polystyrene, can be accommodated in the intrados 11 of the profiled member 2 arranged on the outer side of the structure 100 (Figure 20). Subsequently the nets 104 are positioned to cover the walls 101 on both sides (Figures 21 and 22). The nets 104 are fixed to the profiled members 2, 3 by way of the plates 109. Subsequently the walls 101 are covered with grout 106 (Figure 23).
In order to provide the floor 102 (Figures 24 and 25), a plurality of beams lc are arranged in the intrados 11 of the profiled member 3 of the bond beams lb that face inwardly into the structure 100. The beams lc are connected to the bond beams lb by way of threaded elements which are engaged in the angular plates 8. Panels P are interposed between the beams lc.
Then, the bars 107 are arranged for connecting with the walls 101 of the upper floor (Figure 26), the nets 104 are positioned above and under the floor 102 and the casting is carried out of the concrete 112 that makes up the screed of the level and fills the internal space of the bond beams lb (Figure 27).
Construction can then proceed with providing the upper floor, starting by positioning the pillars la at the plates 115 and going through the operations described above (Figure 28).
Provision of the roof 103 is entirely similar to what is described above for the floor 102 with the difference that the beams lc and the panels P are arranged inclined (Figure 29).
In practice it has been found that the invention as described achieves the intended aim and objects and, in particular, attention is drawn to the fact that the prefabricated structural elements according to the invention make it possible to accelerate and facilitate the execution of the operations on the building site in that such elements are ready for installation and need only to be connected to the supporting structure of the building by way of tightening threaded elements.
Furthermore such system of construction makes it possible to obtain building structures that are stronger and with better thermal insulation characteristics, and which are also made with homogeneous materials and methods.
The invention, thus conceived, is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.
Moreover, all the details may be substituted by other, technically equivalent elements.
In practice the materials employed, as well as the contingent dimensions and shapes, may be any according to requirements without for this reason departing from the scope of protection claimed herein.
