OBJECT OF THE INVENTION
[0001] This invention is based on a large hollow brick, this not being a limitation of sizes
because the solution provided by the invention is applicable to smaller sizes or traditional
sizes provided that the conditions of the cavity so allow, taking into account that
the aim is to provide said hollow bricks with the option of opening up the chasings
necessary for installing service conduits, pipes, tubing, cable troughs or others
without damaging or unduly weakening the construction piece.
[0002] As is known, in walls, partitions, faces or the like built with ceramic materials,
specifically with double cavity bricks, which is most customary and general practice
in construction today, it is necessary to open up chasings in certain parts of the
brick, which advisably must coincide with one of the grooves of the brick, leaving
the space necessary for installing the aforementioned service conduits.
[0003] However in practice, the breaking of the brick or the opening up of the chasing has
some drawbacks, such as the fact that the space of the cavity or section of the groove,
resulting from its standardized 7 cm thicknesses, is not enough for the correct or
complete housing of said installations, forcing the central rib of said brick to be
broken, implying undue and highly unadvisable weakening of the brick which at this
point would be joined only at the rib opposite to the chasing.
[0004] Another drawback is that the location of the grooved part of the brick where the
chasing must be made, generally in the central groove of small or large bricks, must
be done by approximately calculating the area, which does not always give the right
result, though the outside of bricks today indicate the horizontal intersection ribs
with a section that is wider than the common ribbing of the brick.
[0005] The invention has as its purpose adapting bricks in a simple manner so as to not
alter their structure and not complicate the manufacturing process, such that they
adapt to the need for the chasing without weakening their structure, even facilitating
locating the groove corresponding with this adaptation. Nor is it necessary to weaken
the area "to be chased" because most bricks must be used with full strength, although
it could be an optional or exceptional alternative.
BACKGROUND OF THE INVENTION
[0006] In reference to the state of the art, the invention is carried out on common double
cavity bricks with a regular format of 25 x 12 x 9 cm and also for double cavity ceramic
plates such as those disclosed in K 158712-1-2 "HOLLOW BRICK", in which double cavities
are alternatively arranged in a combined version of different widths in which their
distribution is calculated for better performance under the working stresses of said
brick according to plate measurements.
DESCRIPTION OF THE INVENTION
[0007] The invention consists of providing the brick with one or more grooves or cavities
of double cavity bricks, having a section with a width that is greater than the adjacent
one, the latter being reduced in the same proportion by which the first one has been
increased such that the central separation rib between them is eccentric with respect
to the central rib of the remaining grooves of the brick, to the two remaining grooves
in double cavity bricks and greater in number in the ceramic or large double cavity
plates.
[0008] Another detail of the invention is that the groove of the hollow brick chosen for
extension is preferably the central groove. Said extension is provided so as to obtain
sufficient space for the housing and passage of the installation of the service conduits
once the chasing is opened up in said groove, assuring the structural reliability
of the brick given that the central rib or separation rib of this cavity and the adjacent
one, now with a smaller section, would not be affected by the chasing.
[0009] The invention likewise foresees providing the brick with external means for identifying
from the outside the place where the chasing must be made with absolute certainty,
which indication may be an arrow introduced on the lower rib of the groove pointing
out the space to be chased, and even a legend engraved on the clay with an expression
such as "make chasing here", or similar instructions, marking the space to be chased
between said rib and the top portion of the groove prepared for being opened up with
no confusion.
[0010] The chasing is opened up traditionally, leaving a continuous chasing open throughout
the bricks of the same tier which, according to the measurements of the prepared cavity,
shall be enough so as to prevent the intermediate rib from breaking and completely
housing the standard conduits for receiving the wall.
[0011] A broader idea of the features of the invention will be given below in reference
to the sheets of drawings attached to this specification which, in a somewhat schematic
manner and only by way of example, show the preferred details of the invention.
DESCRIPTION OF THE DRAWINGS
[0012]
Figure 1 shows a foreshortened perspective view of a double cavity plate (1) from
one end thereof with a groove (4) prepared for chasing.
Figure 2 shows a view equal to the previous one from the opposite end of said plate
(1).
Figure 3 shows a front elevational view of the plate (1) with the cavity (4) for the
conduits (12).
Figure 4 shows a view similar to the previous one with the cavity (4) open (13) at
the chasing (7).
Figure 5 shows a side elevational view of said cavity
(4) cut away, open at the chasing (7).
Figure 6 shows a front elevational view with the proportion of the cavities (3) and
(4).
PREFERRED EMBODIMENT
[0013] A preferred embodiment of the invention is determined by the example shown in said
drawings, representing a hollow plate (1) of the ribbed type (2) and symmetrical double
cavity (3), in which essentially one of them is a cavity or groove (4) with a larger
section or width in the same proportion by which the adjacent cavity (5) is of a lesser
section or width, and in which the intersection partition (6) between the cavities
(4) and (5) is proportionally eccentric with respect to the symmetrical partitions
(6A) of the remaining symmetrical cavities (3).
[0014] A cavity (4) for chasing is externally demarcated by the space (7) comprised between
the longitudinal ribs (8) below and (9) above, the first one or any of the two externally
provided with an engraved message (10) indicating the place where the chasing must
be made, and even an inscription (11) engraved in the clay, such as "make chasing
here", so as to unmistakably indicate the place where the cut for the chasing must
be made.
[0015] As can be seen in Figure 4, the chasing (13) internally houses the tubing (12) for
installing the conduits (14) such that said tubing (12) does not overflow the space
of the surface (7), having the required size inside the cavity (4) for the purpose
of preventing any alteration or projection on the outer side of the brick (1) for
the corresponding treatment of the wall when the layer of mortar is spread.
[0016] Having sufficiently described the nature of the invention, it is hereby stated for
all intents and purposes that said invention is not limited to the exact details of
this specification, rather on the contrary, those modifications considered appropriate
shall be introduced provided that they do not alter the essential features of thereof
claimed below.
1. A hollow brick with a space for chasing, consisting of bricks or plates (1) with symmetrical
double cavities (3), characterized in that one or more of said longitudinal cavities or grooves (4) arranged for chasing has
a space or width (4) exceeding that of the symmetrical groove (3) and the adjacent
groove has a space or width (5) that is smaller in a directly proportional manner
than cavity (4), between which the vertical rib (6) between the two cavities has an
asymmetrical displacement, also proportional with respect to the symmetrical ribs
(6A) of the brick (1).
2. A hollow brick with a space for chasing in which the space for chasing, according
to claim 1, demarcated by the cavity (4), is externally characterized in that it is a space (7) comprised between the bottom (8) and top (9) longitudinal ribs
in which the first one, or either one of them or both, has an engraved message (10)
and a guidance inscription (11) also engraved in the clay, such as "make chasing here",
or a similar equivalent, giving rise to the chasing (13).
