Definitions

  • the present invention falls within the scope of the production of precast concrete products with properties of transparency to light.
  • the subject of the present invention is a composite mortar-based panel of the type comprising elements translucent to the light.
  • the present invention also relates to a method for making this panel.
  • cementizious products with properties of transparency to light
  • these cementizious products are supplied in the form of mortar building blocks through which optical fibres pass to allow light to be transmitted from one side of the block to the other.
  • the optical fibres are arranged as the weft in special nets or fabrics and thus inserted during casting of mortar in the formwork to produce blocks of variable dimensions depending on their intended use. Plates or panels are then obtained from these blocks, which are subsequently subjected to grinding and polishing.
  • the main aim of the present invention is to provide a composite mortar-based panel of the type comprising elements made of translucent material that allows the aforesaid problems to be solved.
  • a first object is to provide a panel that, using the same amount of mortar, has improved properties of mechanical strength with respect to prior art panels.
  • Another object is to provide a panel whose structure, with the same required mechanical strength, makes it possible to use less prestigious mortars than those currently used.
  • a further object is to obtain a panel that is reliable and relatively easy to make at competitive costs.
  • the present invention thus relates to a composite panel as defined in claim 1.
  • the panel according to the invention is characterized in particular by the presence of an inner structure provided with a reinforcement armature comprising two metal grids. These latter allow the stresses to be evenly distributed inside the panel, advantageously increasing the mechanical strength of the same panel.
  • the use of the two grids makes the use of the polymer material, of which the transparent elements are made, more compatible with the mortar.
  • the grids advantageously increase the total toughness of the panel and allow optimized distribution of the stresses that are generated on the same panel during installation.
  • a cemetitious mortar-based panel 1 comprising a plurality of elements 5', 5", 5'" made of a translucent material which allow the transmission of light through the panel 1 from a first flat side 1' to a second flat side 1" of the same panel.
  • Fig. 1 is a perspective view of a panel 1 according to the invention in which said flat sides 1',1" forming the "main" sides of the panel 1, i.e. those of greater extension, are indicated.
  • the panel 1 has a prismatic configuration developing according to a longitudinal direction 100 and according to a transversal direction 101 which is essentially orthogonal to the longitudinal direction 100.
  • the panel 1 is thus delimited by a first pair of longitudinal sides 2',2" which develop parallel to the longitudinal direction 100 and a second pair 3',3" of transversal sides which develop parallel to the transversal direction 101.
  • the distance between the first side 1' and the second side 1" defines the thickness of the panel 1 (indicated with the reference 80), this distance being evaluated according to a direction essentially orthogonal to the parallel planes on which the two main sides 1',1" develop.
  • the panel 1 essentially has a prismatic configuration in which the two sides 1', 1" develop symmetrically with respect to an intermediate reference plane (indicated with the reference 4) parallel to the same sides. Therefore, this intermediate plane 4 is parallel and equidistant to each of the two main flat sides 1', 1" of the panel 1 (see Figs. 1 and 9 ).
  • the elements 5', 5", 5' preferably made of translucent plastic material, for example PMMA, have an essentially two-dimensional shape, i.e. defined by two parallel sides 7', 7" which develop on planes parallel to each other and orthogonal to the planes 1', 1".
  • the distance between these sides 7', 7" (evaluated according to a direction orthogonal to the development planes of the same sides) defines the thickness (indicated with the reference 81 in Fig. 2 ) of the same element.
  • this thickness 81 is constant for all the elements 5', 5", 5'", although it could also be different.
  • the elements 5', 5", 5'" are arranged inside the panel 1 according to directions parallel to the longitudinal direction 100, i.e. so that each element 5', 5", 5"' develops parallel to the longitudinal direction 100.
  • the elements 5', 5", 5'” are also arranged spaced at predetermined intervals along said transversal direction 101.
  • the term “interval” is intended as the distance (indicated with the reference 83 in Fig. 2 ) between two adjacent elements (for example 5', 5" or 5", 5'") evaluated parallel to the transversal direction 101.
  • the elements 5', 5", 5'" are preferably equidistant along the transversal direction 101, but could also be arranged at different distances, i.e. spaced at irregular intervals.
  • the shape of the elements 5', 5", 5'" defines a plane of symmetry which coincides essentially with the intermediate reference plane 4 indicated above.
  • Figs. 3 and 4 it is possible to observe in detail the shape of these elements 5', 5", 5"' which comprise through portions 55', of greater height spaced apart from inner portions 55" of smaller height so that each inner portion 55" represents a connection portion between two through portions 55' according to an essentially "chain shaped” arrangement.
  • the height of the through portions 55' and of the inner portions 55" is evaluated according to a direction essentially orthogonal to the main sides 1', 1" of the panel 1.
  • the through portions 55' have a height corresponding to the thickness 80 of the panel 1 defined above to transmit light from one of the main sides 1',1" to the other.
  • the portions 55" are instead “inner” portions of the panel 1, in the sense that they are destined to be completely surrounded by mortar which, following a pouring and hardening process, defines the sides of the panel 1. For each element 5', 5", 5'" this alternation of through portions 55' and inner portions 55" defines a pair of grooves 54 for each of the inner portions 55".
  • these grooves 54 in substance form breaks in the longitudinal continuity of the same element, as is clearly visible in Figs. 3 and 4 .
  • These grooves 54 are delimited along the longitudinal direction 100 by two through portions 55'.
  • the corresponding two grooves 54 are symmetric with respect to the reference plane 4, i.e. are defined symmetrically with respect to the same inner portion 55".
  • each element 5', 5", 5' comprises a first end portion 50' and a second end portion 50" opposite to said first end portion 50'.
  • the height of these end portions 50', 50" is lower than the height of the through portions 55' and preferably corresponding to the height of the inner portions 55".
  • the first end portion 50' has a longitudinal extension (indicated with the reference 94') which is the same for all the elements 5', 5", 5'", so as to define a first transversal reference plane 201 (indicated in Figs. 3-4 ).
  • the second end portion 50" also has a same longitudinal extension (indicated with the reference 94") which is the same for all the elements 5', 5", 5'", so as to define a second transversal plane 202 (indicated in Figs. 3 and 4 ) parallel to the first plane 201.
  • the through portions 55' develop longitudinally in a manner spaced apart from the inner portions 55" for a distance corresponding to the distance between the first 201 and the second 202 transversal plane.
  • the elements 5', 5", 5'" are arranged so that the through portions 55' and the inner portions 55" of a first element 5' are longitudinally offset with respect to the through portions 55' and the inner portions 55" of a second element 5" adjacent to the first 5'.
  • the through portions 55' and the inner portions 55" of a first element 5' are respectively facing the "inner” portions 55" and the through portions 55' of a second element 5" adjacent to the first.
  • Figs. 3 and 4 show two mutually adjacent elements 5', 5" made of translucent material.
  • the shape of the first element 5' is different from the shape of the second element 5" near the end portions 50', 50".
  • the through portions 55' develop alternately to the inner portions 55" in the distance comprised between the first 201 and the second 202 transversal reference plane.
  • the through portions 55' of the first element 5' which develop from the first plane 201 and those which develop from the second plane 202 necessarily have a longitudinal extension different from those of the corresponding through portions 55' of the second element 5". More precisely, by comparing Figs.
  • the through portion 55' of the first element 5' which develops from the first plane 201 has a longitudinal extension (indicated with 87') different from the extension (indicated with 87") of the corresponding portion 55' of the second element 5".
  • the through portion 55' of the first element 5' which develops from the second plane 202 also has an extension (indicated with 88') different from the extension (indicated with 88") of the corresponding portion 55' of the second element 5". Consequently, the "offset" longitudinal arrangement can in fact be obtained by arranging a first series of elements 5' as shown in Fig. 3 and a second series of elements 5" as shown in Fig. 4 and arranging these elements side by side along the transversal direction 101 so that each element 5" of the second series is arranged between two elements 5' of the first series, and vice versa.
  • the related first end portion 50' defines a first opening 56', while the second end portion 50" defines a second opening 56".
  • the first openings 56' are aligned along a first transversal alignment axis 105 (indicated in Fig. 2 ), while the second openings 56" are aligned along a second transversal axis (not shown) parallel to said first transversal alignment axis 105.
  • These openings have the function of allowing each element 5', 5", 5" to be connected to a peripheral frame, as better specified in the description below.
  • these openings 56', 56" are preferably in the shape of "slots" in order to promote the passage of elements of the peripheral frame through the same openings.
  • Fig. 5 shows a portion of the inner structure 8 of a panel 1 according to the present invention.
  • the panel 1 is characterized in that it comprises, internally, a reinforcement armature which includes at least one first grid 11 and at least one second grid 12 made of metallic material.
  • a reinforcement armature which includes at least one first grid 11 and at least one second grid 12 made of metallic material.
  • galvanized grids has proved particularly advantageous.
  • the possibility of using other types of grids also falls within the scope of the present invention.
  • the two grids 11,12 have an essentially flat development and preferably have the same shape.
  • the first grid 11 is arranged in a position comprised between the first side 1' of the panel 1 and the intermediate reference plane 4, while the second grid 12 is arranged in a position comprised between the second side 1" of the panel 1 and the same intermediate plane 4.
  • the two grids 11,12 are arranged in symmetric positions with respect to the intermediate reference plane 4. It has been observed that the use of two grids 11,12 arranged on opposite sides with respect to the reference plane 4 (main plane of symmetry) advantageously increases the mechanical strength of the panel 1 and the possible range of mortars that can be used to make the same panel.
  • the use of two grids 11, 12 increases the total toughness of the panel 1 and allows optimized distribution of the stresses generated in the same panel during its installation. It has also be observed that in the arrangement indicated, the two grids 11, 12, make the behaviour of the mortar, in terms of expansion and shrinkage, more compatible with that of the material of which the elements 5', 5", 5"' translucent to light are made. This aspect results in a higher quality of the panel and therefore a greater reliability and duration thereof.
  • Fig. 6 is an exploded view relating to the portion of inner structure 8 of Fig. 5 .
  • the first grid 11 is shown separated from the rest of the structure 8.
  • each of the two grids 11,12 develops longitudinally between the elements 5', 5", 5" and transversally through the grooves 54 defined by the spaced apart arrangement of the through portions 55' and of the inner portions 55".
  • each grid 11, 12 has a shape that branches not only in the space defined between two adjacent elements 5', 5", but also in transversal direction to the same elements through said grooves 54.
  • each grid 11, 12 comprises a plurality of longitudinal segments 21', 21" which develop longitudinally between two adjacent elements 5', 5', 5'" and a plurality of transversal segments 22 each of which crosses a corresponding groove 54 of a corresponding element 5', 5', 5"'.
  • Each of these transversal segments 22 transversally connects two longitudinal segments 21',21" arranged on opposite sides with respect to a same element 5', 5', 5"'.
  • FIGs. 5 and 6 some longitudinal segments 21',21" and some transversal segments 22 have been darkened and indicated with corresponding references purely for descriptive purposes.
  • only one longitudinal segment 21', 21" is provided between two adjacent elements 5'-5" or 5"-5"'.
  • a larger number of longitudinal segments could be provided, above all when the transversal distance between said elements 5', 5", 5'" increases.
  • the longitudinal segments 21', 21" which develop between the same adjacent elements 5'-5", 5"-5'" can be connected by further transversal segments in conformity with a grid configuration.
  • each reinforcement grid 11, 12 comprises a single transversal segment 22 for each of the grooves 54 of each element 5', 5", 5"'.
  • each transversal segment 22 connects a longitudinal segment 21', arranged between the same element 5" and the element indicated with the reference 5', with a longitudinal segment 21" arranged between the same element 5" and the element indicated with the reference 5'" which is opposite to the element 5' with respect to the element 5" taken as reference.
  • the possibility of each groove 54 of the elements 5', 5", 5'" being crossed by a higher number of transversal connection segments falls within the scope of the invention.
  • Fig. 8 is a view of the panel of Fig. 1 at the end of the step for making it.
  • Fig. 9 is a sectional view of the panel 1 of Fig. 8 according to a line with longitudinal section IX-IX which passes through one of the elements made of translucent material. From this view it can be noted how at the end of the manufacturing process, the grooves 54, defined by the alternation of through portions 55' and inner portions 55" of each element 5', 5", 5'", are filled with mortar and crossed by a corresponding transversal segment 22 of a corresponding grid 11, 12. These segments are preferably symmetric with respect to the reference plane 4 of the panel 1 indicated also in Fig. 9 .
  • each grid 11, 12 also comprises a plurality of protruding transversal segments 24', 24" each of which develops in transversal direction 101 from one of the longitudinal segments 21',21" of the grid defining a protruding end 26.
  • each element 5', 5", 5'" there is provided a first series 24' of protruding transversal segments and a second series 24" of protruding transversal segments symmetric to said first series 24' with respect to the same element.
  • This arrangement defines, for each element 5', 5", 5'", a series of protruding end pairs 26 also symmetric with respect to the element 5',5",5"'.
  • the two corresponding ends 26 are arranged symmetrically with respect to one of the through portions 55' of the element 5', 5", 5'", each in a position adjacent to a corresponding side 7', 7" of the same element. This arrangement is clearly visible in the plan view of Fig. 7 .
  • protruding segments 24',24" and above all of the related protruding ends 26, is very advantageous not only in terms of increasing the mechanical strength of the panel 1, but also due to the fact that these ends 26 advantageously facilitate the process for making the same panel 1, constraining the elements 5', 5", 5'" in the correct position during pouring of the mortar.
  • the protruding end pairs 26 act on the opposite sides 7',7" of the same element 5',5",5"' opposing the thrust forces that are generated when the mortar is distributed between the various elements 5', 5", 5"'. Maintaining a correct position of the elements 5', 5", 5'” advantageously results in a higher quality of the panel 1 above all with regard to the light transmission effect obtainable with the same panel.
  • the reinforcement armature of the inner structure 8 of the panel 1 also includes a peripheral frame comprising at least one first rectilinear element 41 arranged transversally (i.e. parallel to said transversal direction 101) and connected to each of the elements 5', 5", 5'" near the first end 50' so as to take a position inside the panel 1.
  • the first element 41 is arranged so as to pass through the first openings 56' of the elements 5', 5", 5'", i.e. takes a position coincident with that of the first transversal alignment axis 105 of said first openings 56'.
  • the reinforcement armature also comprises a second rectilinear element (not shown) arranged transversally and connected to each of the elements 5', 5", 5"' near the second end 50".
  • the second element is also arranged so as to pass through the second openings 56" of the elements 5', 5", 5'" i.e. so as to take a position coincident to that of the alignment axis (not shown) of the same second openings 56".

  • the rectilinear elements of which the peripheral frame is formed can be fixed to one another by welding or alternatively by tying. In this sense, they are preferably made in the form of metal rod. In this regard, the ends of the rods can preferably be flattened to increase adherence with the mortar.
  • peripheral frame As described above gives the panel 1 considerable mechanical strength near the longitudinal 2', 2" and transversal 3', 3" sides of the same panel.
  • peripheral frame cooperating with the reinforcement grids 11, 12, allows correct distribution of the stresses near these sides, which during installation of the panel are affected by the external loads deriving from the presence of other panels.

  • the arrangement of the grooves of the assembly element corresponds to the arrangement of the through portions 55" as these appear, for example, on one side of the panel (see Fig. 1 ).
  • the assembly method of the inner structure 8 thus provides for shaping of the grids 11, 12 using the assembly element indicated above and in particular suitably eliminating the segments around the grooves of the same element, i.e. defining the transversal segments 22 and the protruding segments 24', 24" for the purposed indicated above. Subsequently, one of the two grids, for example the first grid 11, is arranged on the exposed surface of the assembly element so that the protruding segments 24', 24" are placed near corresponding grooves of the assembly element.
  • assembly of the structure 8 provides for positioning of the elements 5', 5", 5'" so that they correspond to the rows of grooves of the assembly element, i.e. so that the through portions 55' of each element 5', 5", 5'" are inserted in corresponding grooves of one of said rows.
  • this step of assembly makes it possible to obtain the arrangement of the elements shown in Fig. 6 .
  • the peripheral frame is then mounted so as to mutually block the same elements.
  • the rectilinear transversal elements of the peripheral frame are first positioned through the first openings 56' and the second openings 56" defined above. Subsequently, the longitudinal rectilinear elements are mounted so as to complete the shape of the peripheral frame.

In this way, the longitudinal development direction 100 of the panel 1 coincides with the vertical development direction 103 of the formwork 200.
  • the mortar 300 is then poured as depicted in Fig. 11 . The mortar is thus poured vertically between the elements, i.e. according to a pouring direction that is parallel to the development direction of the elements.
