[0001] The present invention relates to a wall structure for plaster.
[0002] Nowadays on wall surfaces or wall faces, it is known to distribute and smooth a layer
of plaster as a finishing element, on which to then apply for example a subsequent
tinting.
[0003] A problem that is encountered is the formation of cracks, which arise more frequently
when for example profiles made of aluminum or PVC or galvanized sheet metal are inserted
in the wall, or staff angles of aluminum or PVC are mounted on the corners of the
wall.
[0004] Such cracks are produced by the different thermal dilation of heterogeneous materials.
[0005] Profiles of galvanized sheet metal are for example indicated for plasters based on
lime, lime-cement, cement or plaster of Paris, while profiles of aluminum are indicated
for plasters based on plaster of Paris and for grouting made of synthetic resin.
[0006] Problems also arise with the gripping of the plaster to such profiles and staff angles.
[0007] As a partial solution to the problem of the formation of cracks, it is known to apply
a mesh on the surface of the wall prior to applying the plaster; however, this solution
also presents drawbacks, in that the gripping is not always optimal, since cracks
could still arise owing to the possible incorrect arrangement, dilation and/or non-conformance
of the mesh.
[0008] The aim of the present invention is therefore to solve the above-mentioned technical
problems, eliminating the drawbacks in the cited known art and thus devising a wall
structure for plaster, on the flat surface of which one or more inserts or staff angles
are applied, which makes possible the optimal application of at least one layer of
plaster that will last over time.
[0009] Within the above aim, an object of the invention is to provide a wall structure for
plaster invention that makes it possible to apply a layer of plaster on a wall which
will be free from cracks over time.
[0010] Another object is to provide a wall structure for plaster that is also usable if
there are inserts made of PVC for door or window frames, or staff angles, on the wall.
[0011] Another object is to provide a wall structure for plaster that can be provided with
the usual systems and machinery and which is structurally simple.
[0012] This aim and these and other objects which will become better apparent hereinafter
are achieved by a wall structure presenting a surface that is adapted to the application
of at least one layer of plaster, characterized in that one or more seats are provided
on said surface for gripping said at least one layer of plaster.
[0013] Further characteristics and advantages of the invention will become better apparent
from the detailed description of a particular, but not exclusive, embodiment, illustrated
by way of non-limiting example in the accompanying drawings wherein:
Figure 1 is a first perspective view of a section of wall structure according to the
invention in which grip seats are provided;
Figure 2 is a front elevation view of the section of wall structure of the previous
figure;
Figures 3, 4, 5, 6, 7, 8, 9 and 10 are side views of a section of wall structure in
which different grip seats are provided.
[0014] In the embodiments illustrated, individual characteristics shown in relation to specific
examples may in reality be interchanged with other, different characteristics, existing
in other embodiments.
[0015] With reference to the figures, the reference numeral 1 generally designates a generic
wall structure that can be used for a door, a roller blind, a bevel, an awning, a
roll-up element or the like.
[0016] In Figures 1 and 2, the specific embodiment is a wall structure 1 such as a single-piece
shoulder for plastering that can be used in order to provide for example the products
that the applicant currently markets with the names/trademarks "INQUADRA", "RIQUADRA",
"TIQUADRA" and all the solutions for plastering, and which are provided with a body
2 for smoothing-out made of EPS (for example complying with the percentage recycled
materials specified by the minimum environmental criteria (CAM), with a thermal conductivity
value equal to 0.034 W/m2k), which is associated with a profile with wall anchors
3, wood inserts 4, an end profile 5 made of PVC, a preguide 6 for a roll-up element,
and a staff angle 7, all in order to obtain a product for the insulation of the window
opening with window frames flush with the wall and centered in the wall, for a roll-up
element, but also for shades, awnings, shutters or without any system of shade (window
frame only).
[0017] The body 2 of the wall structure 1 has a surface 8 to be smoothed out, on which therefore
at least one layer 9 of plaster can be applied.
[0018] On the surface 8 there are one or more seats 10 of a chosen shape, the function of
which is to enable an optimal grip for the at least one layer 9 of plaster.
[0019] The seats 10 therefore advantageously are dovetail-shaped in cross-section, as shown
in Figures 1, 2, 3 and 4.
[0020] This shape structure enables the plaster to grip the surface 8 in an optimal manner
given that part of it comes to be positioned and retained under the teeth 11 defined
with the dovetail-shaped machining.
[0021] Thus it has been found that the wall structure according to the invention fully achieves
the intended aim and objects, a solution having been devised that makes it possible
to obtain the optimal application of at least one layer of plaster, in so doing obtaining
a uniformity of finish between rabbet and facade.
[0022] Furthermore, it is possible to use a staff angle or other accessories made of PVC,
which are completely embedded in the plaster applied during the work, in the rabbet
and in the facade, at the same time being free from cracks.
[0023] The solution to the above aim and objects is also achieved by the embodiment illustrated
in Figure 3 which makes it possible to achieve equal utility by using the same inventive
concept.
[0024] In fact, a generic wall structure 1 has been illustrated, which is provided with
staff angle 7 and end profile 5, but lacking a preguide 6, in which one or more seats
10 are provided on the surface 8 which are dovetail-shaped in cross-section.
[0025] Similarly, Figure 4 shows a wall structure 1 provided with a staff angle 7, three
end profiles 5 and a preguide 6 for an awning, in which one or more seats 10 are provided
on the surface 8 which are dovetail-shaped in cross-section.
[0026] Similarly, Figure 5 shows a wall structure 1 in which the body 2 also has a surface
8 on which multiple seats 10 are provided which have the shape of a sinusoidal wave
in cross-section.
[0027] Similarly, Figure 6 shows a wall structure 1 in which the body 2 also has a surface
8 on which multiple seats 10 are provided which are triangular in cross-section.
[0028] Similarly, Figure 7 shows a wall structure 1 in which the body 2 also has a surface
8 on which multiple seats 10 are provided which are semicircular in cross-section.
[0029] Similarly, Figure 8 shows a wall structure 1 in which the body 2 also has a surface
8 on which multiple seats 10 are provided which have the shape of a scalene trapezoid
in cross-section so as to define a sequence of teeth 11 which extend on an inclined
plane in the same direction as, or in a different direction to, that of said surface
8.
[0030] Similarly, Figure 9 shows a wall structure 1 in which the body 2 also has a surface
8 on which multiple seats 10 are provided which are hexagonal in cross-section so
as to define a sequence of teeth 11 which are arranged, for each seat 10, mutually
opposite.
[0031] Similarly, Figure 10 shows a wall structure 1 in which the body 2 also has a surface
8 on which multiple seats 10 are provided which are rectangular in cross-section.
[0032] The invention is of course susceptible of numerous modifications and variations,
all of which have equal utility and are within the scope of the appended claims.
[0033] The materials used, as well as the dimensions that constitute the individual components
of the invention, may of course be more pertinent according to the specific requirements.
[0034] The various means of achieving certain different functions certainly need not coexist
only in the embodiment shown, but may be present in many embodiments, even if they
are not shown.
[0035] The characteristics indicated above as advantageous, convenient or the like, may
also be missing or be substituted by equivalent characteristics.

those reference signs have been included for the sole purpose of increasing the intelligibility

on the interpretation of each element identified by way of example by such reference
