[0001] building structures create considerable practical problems both from a formation
viewpoint and as regards the connection thereof to parts that are not made of concrete.
Such practical problems could be solved by placing suitably sized burnt clay elements
around the concrete. This being the situation, the technical task forming the basis
of the invention is to devise a block which, apart from specific uses of a conventional
type, can also be utilized in various ways in a building structure, so as to overcome
the above mentioned shortcomings.
[0002] One important object within the framework of the said technical task is to devise
a block able, at the choice of the user, to adopt a variety of structural configurations
without any need for adaptation operations that are complex or call for the use of
special equipment.
[0003] Another, though not final, object of the invention is to devise a block that is simple
and can easily be produced by industries in the field concerned.
[0004] These objects and others too that will become more apparent below are achieved with
the multiple use building trade block according to the invention, of the type defined
by a flat burnt clay element comprising a first main surface and a second main surface
interconnected by a plurality of side-by-side ribs that form there with channels parallel
both one to the other and to the main extension direction of the said burnt clay element,
two of the said plurality of ribs defining the longitudinal sides of the said element,
and characterized by the fact of comprising : a resistant part defined by the said
first main surface and by at least the said two ribs that form the longitudinal sides
of the said element, and an auxiliary part defined by the said second main surface
and by the remaining ribs, the said resistant part having cross sections greater than
those of the said auxiliary part.
[0005] Pared corners are advantageously provided in the areas of connection between the
said resistant part and the said auxiliary part in order to encourage the separation
one from the other of these.
[0006] Further characteristics and advantages will be seen more clearly from the description
that follows of one preferred, though not sole, embodiment for the block according
to the invention, illustrated purely as an unlimited example on the accompanying drawings,
in which :
- Figure 1 shows, in a front view, the structure of the block forming the subject
of the invention;
- Figure 2 shows, in a perspective view, the block illustrated in Figure 1 connected
to a layer of concrete;
- Figure 3 shows, in a cross sectional view of a building structure, two resistant
parts of the block illustrated in the preceding figures;
- Figures 4 and 5 show, in horizontal sectional views of a building structure, resistant
parts of the block illustrated in Figures 1 and 2 positioned in the region of columns;
- Figure 6 shows, in a vertical sectional view of a building structure, the base area
of a window, in particular where the horizontal element of the window is located;
- Figures 7 and 8 show, in horizontal sectional views of a building structure, the
area where a vertical element of a wooden frame window is installed;
- Figure 9 shows, in a similar sectional view to those in Figures 7 and 8, the area
where a vertical element of a metal frame window is installed.
[0007] With reference to the above listed figures and, in particular to Figures 1 and 2,
the block according to the invention is shown globally at 1. Constituted in a way
in itself known by a flat burnt clay element, the block is provided with a first main
surface 2 and a second main surface 3 that define the longest surfaces of the said
element. The surfaces 2 and 3 are interconnected by a plurality of ribs subdivided
into central ribs 4 and border ribs. The latter define the principal longitudinal
sides 5 of the block 1.. Running between the said ribs are channels 6 that are parallel
both one to the other and to the main extension direction of the block 1.
[0008] An original aspect of the invention is that the block 1 is fundamentally subdivided
into parts: namely a resistant part 7 and an auxiliary part 8. In the case illustrated,
the resistant part 7 is defined by the first main surface 2 and by the longitudinal
sides 5 of the block 1. The auxiliary part 8 is, instead, defined by the second main
surface 3 and by the central ribs 4. The resistant part 7 has cross sections greater
than and preferably double those of the said auxiliary part.
[0009] In actual practice, the resistant part 7 is essentially of a "U" shape that is interrupted
only by localized enlargements in, out of preference, the region of the corners.
[0010] Another original aspect envisages that in the areas of connection between the resistant
part 7 and the auxiliary part 8 the separation of one part from the other be encouraged
by the concavities shown at 9 that are preferably defined by recesses fashioned at
the time the block is being made. The block, in common with burnt clay elements in
general, is produced by simple extrusion.
[0011] The highly assymmetrical structure of the block 1 and the lack of difficulty in separating
the resistant part 7 from the auxiliary part 8 influence considerably the possible
uses to which the said block 1 can be put in the building trade and lead to the formation
of building structures which, in themselves, are original.
[0012] In the first place, as is shown in Figure 2, the block 1 can be utilized in the construction
of horizontal frameworks. When employed in this way, the block 1 is used complete
with all the parts thereof, and the resistance offered by the part 7 enables particularly
light layers 10 of concrete to be formed.
[0013] Apart from the said use, in itself of a conventional nature, the block 1 according
to the invention can unconventionally be utilized to circumscribe pipework etcetera
and for non re- utilizable structure shuttering.
[0014] As regards the circumscription of pipework etcetera 11 (Figure 3), the block 1 is
utilized removing there from the auxiliary block 8 and leaving there with the resistant
part 7, with the typical "U" shape of this.
[0015] As can be seen from the said figure, it is possible with the resistant part 7 to
install all types of pipes etcetera 11 without these being bricked in or buried under
the flooring. In this way, the heavy layer with which to level the flooring substructure
is dispensed with, thereby reducing costs and overloads. Furthermore, it becomes possible
in this way to inspect the pipework etcetera 11 and the installation thereof does
not interfere with the work in hand (the laying of bricks and electrical/sanitary
installations etcetera) since bricking in assistance is minimum.
[0016] The resistant parts 7 can be utilized for the circumscription not only of pipework
etcetera in newly constructed buildings but also when old buildings are being restored
and every time it is wished to update obsolete or deteriorated plants. In this way,
the danger of breakages due to stray voltages and galvanic currents is eliminated
and, above all, every one of the problems originated by the pre-existing constructional
technique, in itself costly and erroneous from both a functional and a rational viewpoint,
is obviated.
[0017] Figure 4 shows, in a plan view, the double columns 12, and Figure 5, a single column
12. The said columns or elements of support are delimited by resistant parts 7 that
replace the customary shuttering. Thanks to this, the columns can be formed in a fast
and simple way; furthermore, it is possible to leave open parts 13 that allow the
concrete to spread and join, one to the other, two columns or to seal the spaces in
between a column and the non-bearing wall 14.
[0018] With the block 1 according to the invention it is possible to build framed structures
that comply with the current requirements for aseismatic projects wherein the peripheral
brickwork structural units can be rendered active with respect to the resistance and
distribution of the shearing forces applied thereto.
[0019] In particular, the blocks 1 allow the construction not only of a main frame defined
by girders and columns but also of an auxiliary strengthening frame defined by the
pillars 17 placed preferably in a position wherein able to form the vertical support
elements of the windows, and by the cross beams 16 that can define the horizontal
support elements of the windows.
[0020] In Figures 7 to 9 it can, in fact, be seen how the horizontal and vertical delimitation
of the apertures 15 can lead, with the use of the resistant parts 7, to cross beams
16 and to pillars 17 that extend beyond the boundaries of the apertures 15 in order
to define the said auxiliary frame, that is to say, a meshed structure that breaks
up the area and notably increases the rigidity of the building structure.
[0021] With the peripheral strength thus created, the rigidity centre of gravity of the
building is brought close to the masses thereby decreasing the incidence of torsion
in the event of oscillations. This brings about a reduction in costs since the need
to distribute the meshes in the frames becomes less important : when the spans of
the peripheral columns and girders are fractionized and there is a considerable increase
in the ductility and rigidity of these, a great percentage of the shearing forces
is absorbed by the peripheral frames.
[0022] In addition to a reduction in the costs of the structure, what is also achieved is
the possibility to proceed more freely with a project since, for example, the cross
section of the inside columns can be decreased and the said columns can be positioned
more freely.
[0023] Furthermore, Figures 7, 8 and 9 show that the formation of the said auxiliary frame,
in particular the pillars 17 that define the vertical elements of the windows, does
not give rise to limitations in the shape of the said pillars.
[0024] They can, in fact, extend in various ways compatibly with the required bracing action
and with the type of frames (wooden 18 or metal 19) provided in the region of the
aper- .tures 15.
[0025] It should also be noted, again with reference to Figure 3, that with building structures
comprising concrete parts 20 alternating with the said brickwork parts 14, the latter
can be interconnected by the resistant parts 7 placed astride of the concrete parts
20, which can be girders 21, on the outside surface thereof.
[0026] In practice, the block 1, with the auxiliary part 8 removed, is placed in position
at the same time as the non-bearing wall 14. The concrete 20 laid compresses and seals
the said wall thereby eliminating the danger of flaws between this and the concrete
part.
[0027] Thus the invention attains the objects proposed. Particular stress is laid on the
fact that the block according to the invention makes it possible to erect not only
more rational and better organized building structures, as shown in Figure 3, but
also building structures with which the essential advantage is achieved of the peripheral
resistance being, at will, easily increased. The shearing forces applied to the inside
frames are eliminated and this is beneficial to the architectural requirements since
the use is possible of girders and pillars of a limited size, as well as of assymmetrical
mesh frames.
[0028] The invention as described herein is liable to undergo numerous modifications and
variants, all of which falling within the conceptual framework thereof.
[0029] Furthermore, all parts may be substituted with other technically equivalent elements
and, in practice, the materials used, as also the shapes and sizes thereof, can be
any to suit the needs.

Multiple use building trade block and building structure utilizing the said block
The invention relates to a multiple use building trade block and to a building structure
utilizing the said block.
As is known, blocks are hollow burnt clay elements of standard sizes used prevalently
in the construction of horizontal frameworks and, in particular, for tile lintel or
steel and tile floors.
Those in use at present are, in practice, defined by two main surfaces connected one
to the other by ribs perpendicular thereto and also defining, at the lateral extremities,
the principal longitudinal sides of the blocks.
Thus the overall structure is perfectly symmetrical and, indicatively, lengths of
around one metre, widths of a few tenths of a centimetre, and gauges in the region
of ten centimetres are envisaged.
The blocks described summarily above are satisfactory for the use stated (namely the
construction of horizontal carrying structures) but fail to meet the requirements
for uses of a different nature. In particular, the above described blocks are also
unsuitable for those uses that, on general lines, would appear to fall in line with
the ample, substantially hollow, conformation thereof. For example: in building structures
it is useful to create channels in which to house pipes etcetera, so as to prevent
these from being either bricked in or buried underneath the flooring, as is generally
the case. Furthermore, the concrete parts in
