[0001] This patent concerns the prefabricated walls used in civil, industrial and farming
buildings, cold stores, slaughterhouses, etc.
[0002] Curtain walling panels or gypsum wallboard partitioning panels are attached to floors
or foundations by means of a straightforward metal or plastic U-shaped profile fixed
to the floor with screws. To fix the partitioning panels adequately, however, it is
important to use U-shaped profiles of exactly the same width as the thickness of the
panel.
[0003] When a room is divided, partitioning panels of different thicknesses are used, e.g.
a greater thickness for the main partitions and a narrower thickness for the other,
secondary partitions.
[0004] As a consequence, different profiles of suitable width for each panel have to be
purchased, cut to size and attached to the floor, with the corresponding economic
cost and inconvenience of more shorts, alignments and connectors.
[0005] Moreover, this situation obliges us to keep numerous profiles of different width
in stock, even if they are only rarely used.
[0006] The above-described systems for fixing partition walls also present several severe
drawbacks.
[0007] In some rooms, e.g. slaughterhouses and cold stores, it becomes necessary for reasons
of hygiene to clean and wash the floor and walls very frequently. This washing and
cleaning is done with jets of water under pressure. That is why the walls and floors
of such rooms are coated with a water-repellent lining and the prefabricated panels
and walls used to divide such rooms comprise an insulating layer coated on the main
surfaces with a water-repellent layer.
[0008] Both rainwater and the water or other fluids used for cleaning can seep between the
floor and the bottom edge of the panel, wetting the floor of the inner or adjacent
room.
[0009] The liquid filtering between the floor and the wall can carry dirt and infections
that stagnate in the space between the bottom edge of the panel and the floor, which
thus becomes a trap for germs that is difficult to clean and makes all subsequent
cleaning and disinfecting operations scarcely effective.
[0010] Moreover, the water and washing fluids may penetrate inside the U-shaped profile
fixing the panel to the floor and soak into the bottom of the panel's insulating layer,
leading to the rapid deterioration of the panel.
[0011] In some cases, attempts have been made to avoid these problems by providing silicone
linings in the various cavities, with the result of making it difficult and laborious
to rearrange the partition walls and interfering with the level of hygiene achievable
in the rooms concerned.
[0012] To overcome all said drawbacks, modular profiles have been studied and developed
for attaching prefabricated curtain or partition walls to floors or foundations, thereby
providing a skirting strip.
[0013] The aim of the new modular profiles is to enable the bottom edge of prefabricated
partition walls of any thickness to be fixed to the floor.
[0014] Another aim of the new modular profiles is to adhere perfectly to the surfaces of
the wall and floor, thereby preventing any infiltration and seepage of water or other
fluids.
[0015] A further aim of the new modular profiles is to enable a straightforward and rapid
rearrangement of the walls.
[0016] These and other direct and complementary aims are achieved by the new modular profiles
for fixing prefabricated walls to floors or foundations, complete with a skirting
strip, comprising a base element, a side element, a bridging element, a side support
for the skirting strip, and side skirting strips.
[0017] The base element has a generically comb-like cross-section, i.e. it has one flat
side and a series of cavities, generically with a droplet-like shape, on the opposite
side. This base element is attached to the floor, e.g. by means of screws, in the
position where the partition wall panels are to be installed.
[0018] The side elements have a generically right-angle triangular cross-section with their
oblique side forming a concave arch, acting as the skirting strip, and extending beyond
the straight sides of the generically triangular shape. These portions extending beyond
the straight sides are flexible, being made of a different material and/or being thinner.
[0019] On one of the two straight sides there is a wing extending outwards from the generically
triangular cross-section, parallel to the other side, with a raised rim at the end.
Said rim has a generically spherical or droplet-like shape and is designed to fit
into the cavities in the above-described base element.
[0020] These side elements retain the bottom edge of the partition wall panel while their
flexible portions adhere to the surface of the partition wall panel and to the floor.
[0021] Depending on the thickness of the wall panel, the raised rims on the side elements
will fit into the innermost, intermediate or outermost cavities in the base element.
[0022] Other, larger-sized side skirting strips are provided, for attaching to suitable
side skirting supports. The larger side skirting strips have an arched shape, with
flexible ends, and they snap onto the aforementioned side skirting supports. The side
skirting supports have a generically triangular shape with a wing complete with a
droplet-shaped rim that can be attached to the base element. Both the side elements
and the side supports serve the purpose of containing the wall.
[0023] For thicker partition wall panels, there are also jointing elements comprising a
flat panel fitted at the ends with generically droplet-shaped raised rims lying perpendicular
to said flat panel and facing the same side, so as to couple two base elements lying
side by side
[0024] The characteristics of the new modular profiles for fixing prefabricated partition
walls to floors and forming a skirting strip will be better explained by the description
that follows, referring to the attached drawings, which serve as a non-restrictive
example.
[0025] Figure 1 shows a cross-section of the base element (F), figures 2a and 2b show a
cross-section of the open and closed side element (R), figure 3 shows a cross-section
of a budging element (G), figures 4a, 4b and 4c show the skirting side support (Ma)
and two side skirting strips (Mr1) and (Mr2), respectively.
[0026] Figures 5 and 6 show two examples of the application and use of the modular elements
(F, R, G, Ma, Mr1, Mr2) for attaching a wall panel (T) to the floor (P).
[0027] The base element (F) has a generically comb-like cross-section, i.e. it has a flat
underside (F1) and a series of generically spherical or droplet-shaped cavities on
the top (F2).
[0028] The flat side (F1) of the base element (F) is designed to enable the base element
(F) to rest on the floor.
[0029] The cavities (F2) on the other side of the base element (F) lie parallel to each
other and to the extruded edge of the base element profile (F). These cavities (F2)
have a preferably circular cross-section with an opening at the top that is narrower
than their diameter.
[0030] In a position preferably central to the base element (F), between and parallel to
the cavities (F2), there is a groove (F3) to allow for the insertion of a screw (V)
for fixing the base element (F) to the floor.
[0031] The side elements (R) have a generically right-angle triangular cross-section with
the oblique side forming a concave arch (R3) and extending beyond the straight sides
(R1, R2) of the generically triangular shape.
[0032] The portions (R3e) of said arched side (R3) that extend beyond the other two straight
sides (R1, R2) are flexible, i.e. they are made of another material and/or are thinner
[0033] On the inner surface of the said arched side (R3) there is a tooth (R3d) or an arrow-shaped
rib.
[0034] On the vertical straight side (R1), hereinafter called the first straight side (R1),
there is a tooth (R1d) facing towards the inside of the triangular shape, and a wing
(R1a) extending outwards from the triangular shape
[0035] This wing (R1a) is generically horizontal and lies parallel to the second straight
side (R2), and it has a spherical or droplet-shaped rim (R1ar) facing downwards on
its free end.
[0036] This rim (R1ar) is designed to fit into the droplet-shaped cavities (F2) in the base
element (F).
[0037] The above-described side element (R) is such that the two straight sides (R1, R2)
are joined together, while the arched side (R3) is jointed-hinged onto the outer end
of the second straight side (R2). Basically, this arched side (R3) is open, i e. it
is detached from the first straight side (R1), before and during the application of
the side element (R) onto the base element (F), and it is subsequently closed, i.e.
it is turned towards the first straight side (R1), so that its tooth (R3d) becomes
hooked onto the tooth (R1d) on the first straight side (R1). In the closed position,
the ends (R3e) of the arched side (R3) press against and adhere to the floor (P) and
to the partition wall panel (T).
[0038] The jointing elements (G) are composed of a flat panel (G1) fitted at the ends with
generically spherical or droplet-shaped rims (G2) that face downwards.
[0039] These jointing elements (G) are used to couple two base elements (F) lying side by
side and thereby enable thicker panels (T) to be fixed to the floor (P).
[0040] The side skirting support (Ma) is substantially composed of walls (Ma1, Ma2, Ma3)
similar to the walls of the side element (R), with the corresponding wing (Maa) complete
with a rim (Maar). In particular, the arched wall (Ma3) of the side skirting support
(Ma) has a tooth (Ma3d) in the vicinity of the bottom wall (Ma2), and an arched rim
facing upwards (Ma3u) in the vicinity of the top end of said arched wall (Ma3).
[0041] The small side skirting strip (Mr1), illustrated in figure 4b, is composed of a boxed
section, or two arched walls (Mr1a, Mr1b) lying generically parallel and coupled together
by various intermediate small partitions (Mr1c).
[0042] The outer arched wall (Mr1a) extends further than the inner arched wall (Mr1b) and
its ends are flexible, being made of a different material and/or having different
thickness.
[0043] The inner arched wall (Mr1b) has loops or grooves (Mr1d, Mr1e) designed so as to
hook over the arched rim (Ma3u) and the tooth (Ma3d) on the side skirting support
(Ma).
[0044] A large side skirting strip (Mr2), illustrated in figure 4c, is similar to, but higher
than the previously-described small side skirting strip (Mr1).
[0045] In particular, this large side skirting strip (Mr2) has a portion of the outer arched
wall (Mr2a) that can be opened and closed (Mr2f), to allow for the passage and insertion
of a screw (V) for fixing said large side skirting strip (Mr2) to the partition wall
panel (T).
[0046] The various modular profile elements (F, R, G, Ma, Mr1, Mr2) for attaching prefabricated
walls (T) to floors (P) and forming a skirting strip are thus installed in a few simple
steps.
[0047] The base element (F) is fixed to the floor (P) along the line of installation of
the vertical wall (T) with the aid of several screws (V) inserted in the central groove
(F3), between the droplet-shaped cavities (F2).
[0048] In the event of the side elements (R) being used, these are attached to said base
element (F) so that their spherical or droplet-shaped raised rims (R1ar) fit into
a cavity (F2) in the base element (F). In particular, these spherical or droplet-shaped
rims (R1ar) are inserted into the most suitable cavity (F2), so that the first, vertical
straight side (R1) of the two side elements (R) attached to either side of the base
element (F), comes exactly up against the partition wall panel (T)
[0049] The arched wall (R3) of the side elements (R) is left open, i e. it is unhooked from
the first straight side (R1).
[0050] The partition wall panel (T) rests on the base element (F), between the two side
elements (R).
[0051] Finally, the arched walls (R3) of the side elements (R) are closed, i.e. they are
turned up until the tooth (R3d) on the arched wall (R3) hooks onto the tooth (R1d)
on the first straight wall (R1). The ends (R3e) of the arched wall thus adhere perfectly
to the surface of the floor (P) and of the partition wall panel (T).
[0052] In the event of the panel (T) being of considerable thickness, two or more base elements
(F) can be attached to the floor side by side and coupled with bridging elements (G).
[0053] When the side skirting strips (Mr1, Mr2) are used, the corresponding side skirting
supports (Ma) are attached to the one or more base elements (F) and the partition
wall panel (T) is placed between them, where the wall (Ma1) of the side supports (Ma)
serves the purpose of containing the panel (T).
[0054] Finally, suitable side skirting strips (Mr1, Mr2) are attached to said side skirting
supports (Ma), as necessary.
[0055] The new modular profile elements (F, R, G, Ma, Mr1, Mr2) for fixing prefabricated
partition wall panels (T) to floors (P) and forming a skirting strip, constituted
as described above, offer the following considerable advantages.
[0056] The new modular profiles enable the bottom edge of prefabricated partition walls
of any thickness to be fixed in place simply by attaching the side elements (R) or
side skirting supports (Ma) in suitable positions on the base elements (F). There
is no need for a variety of different elements for fixing the partition wall panels
(T), since the above-described modular profile elements (F, R, G, Ma, Mr1, Mr2) adapt
to any thickness of partition wall panel (T).
[0057] The modular profile elements (F, R, G, Ma, Mr1, Mr2) can easily be removed and repositioned
numerous times.
[0058] The flexible ends of the side elements (R) and of the side skirting strips (Mr1,
Mr2) adhere perfectly to the surfaces of the partition wall (T) and floor (P), thereby
preventing any infiltration or seepage of water or other fluids.
[0059] Figure 7 shows a preferred alternative solution, where the base element (F') has
its flat side (F1') uppermost and a set of cavities (F2') in the underside. In the
middle of the element (F') there are one or more seats (F3') for fixing screws. Congruously,
the side element (R') is complete with a tooth (R1 ar') that faces upwards, suitable
for inserting in the cavities (F2').
[0060] Figure 8 shows the end sealing element (Z), or plug, complete with a wall (Z1) and
edges (Zb), and the corresponding devices for its insertion and hook-up (Zx), suitable
for fitting into the cavities (F2). This element can be divided into two parts, depending
on the thickness of the wall.
[0061] Figure 9 shows a corner element (A) composed of a flat bottom part (A1), that is
basically square with a rounded angle (Ar), and devices (A2) for hooking together
the profiles (F) on two adjacent sides, in order to connect two profiles (F) lying
at right angles to each other with the aid of pins (A2) designed to fit into the cavities
(F2).
[0062] The resulting spaces or small compartments, e.g. those coming between the wall (R3)
and the walls (R1) and (R2), could be affected by the formation of colonies of moulds,
bacteria and other harmful organisms. To prevent this from happening, these spaces
are saturated with a PVC foam or other filler.
