This construction element (1) is made of glass fiber composite, which is manufactured by pultrusion and possesses good specific mechanical and thermal isolation properties, compared to the conventional materials used in the buildings. The fibers (2) of the composite of this construction element are perpendicular to the axis of torque that is acting on it, this torque arising from the forces that act on the additional structures (5). The construction element (1) also features holes (3) or different mounting points to be connected to other construction elements (5, 6, 8, 9).
Description
The solutions to thermoregulation problems are very
important in modern buildings. It is required to sustain a relatively stable
temperature inside buildings under the effects of hourly and seasonal
temperature fluctuations, sun radiation and other factors that influence the
temperature of the buildings. Because of this, materials used in building
constructions must be chosen adequately. In ideal case, these materials should
have infinitesimal thermal conductivity and thermal expansion coefficient, or
the latter should be as close as possible to the thermal expansion coefficients
of other materials used in the same building. When structures that carry
exterior finish are made of conventional materials such as metal, despite
ensuring a sufficient thickness of thermal insulation, thermal bridges are
frequently formed that reduce the overall effectiveness of thermal insulation
of the building.
Other very important attribute of materials used in
modern buildings is the ratio between mechanical strength and density of the
material. When ambitiously shaped buildings are to be built, it is often
necessary to choose materials that are sufficiently strong but yet light. This
results in a higher ratio between the load that a construction can carry and
its own weight. Even when employed in conventional buildings, lighter materials
enable lower overall material usage.
European patent EP1460191, published on 22nd
September 2004, describes a support for façade panels of a curtain wall. It
mainly consists of a body upon which is provided at least one laterally
directed wing, whereby the body can be fixed on the post of a curtain wall and
whereby, on the laterally directed wing, can rest a façade panel. This support
distinguishes from others as it is made of a fire retardant material,
preferably steel. The steel used in this invention, having a relatively high
thermal conductivity acts as a thermal bridge between the façade of the
building and its load bearing structures. Moreover, because of the relatively
high density of steel this support is relatively heavy for some particular
required stiffness. As a result, the load bearing structures must carry
otherwise unnecessary weight.
European patent EP2194208, published on 9th
June 2010, presents a wall holder for façade plates. This holder has a
wall-sided mounting element made of metal and a metal profile-sided mounting
element made of metal. The metal profile-sided mounting element is mounted on
the wall-sided mounting element in a connecting area by a connecting element,
particularly a screw. An insulating element is provided between the surface
areas of the mounting elements in the connecting area. The insulating element
is made of hard rubber, plastic or a fiber-reinforced material, and one of the
mounting elements is made of aluminum. An independent claim is included for a
facade cladding with a facade panel. As the isolating element is positioned
between the fixed elements and screws run through all of them, directly
connecting the wall-sided mounting and metal profile-sided mounting elements,
thermal bridge is not avoided. Because of this, thermal properties of the
isolating element are not used to the full potential.
The aim of this invention is to present a load
transferring construction element that forms a gap for thermal insulation
purposes and which would not have the previously mentioned disadvantages. The
described construction element is made of a glass fiber reinforced composite
profile, which itself is made by pultrusion. This manufacturing method ensures
high composite quality and significantly reduces the costs when compared to the
conventional glass fiber composite manufacturing methods.
Glass fiber composite, when compared to the
conventional materials used for building constructions, has exceptionally high
specific mechanical strength. Furthermore, the glass fibers span over the whole
length of the construction element described in this patent. As a result, this
construction element is lighter and stiffer than most of the analogues. Because
of the low thermal conductivity, this construction element is especially
suitable when there is a need to transfer mechanical loads through a non-rigid
thermal insulation layer without creating a thermal bridge, for example, when
such thermal insulation is made of glass wool. The most appropriate application
of the invention is as a mounting element between façade panels or other
external finish and the load bearing structures of the building.
The drawings presented here depict the preferred
embodiments of the invention and their applications. The drawings are
explanatory only and do not limit the scope of the invention in any way and may
not be to scale or ratio.

In the most preferred embodiment of the invention,
depicted in Figure 1, the presented building construction element (1) is made
by cutting it from a flat glass fiber composite bar, which itself is made by
pultrusion. The cuts are perpendicular to the glass fibers (2). The length of
the element (1) is chosen according to the thermal insulation gap dimension.
Its width and thickness are subsequently chosen according to the predetermined
length of the element, the loads it must bear and permissible deformation under
these loads. The end of the element (1) to which the additional building
structures (5) are attached features two holes (3), which are both positioned
at the same distance from the cutting edge of the bar and are symmetrically
positioned with respect to a centerline spanning along the length of the
element. The other end features two pairs of these holes positioned in the same
configuration. The diameter of these holes is chosen according to the geometry
of predetermined rivets (4) or screws. Each of the holes are positioned in such
a way that the rivet (4) or screw going through it would directly connect the
glass fiber composite construction element (1) only to the additional building
structure (5) or to the load bearing building structure (6), or with only one
supplementary construction element (8, 9) that is connected to one of the said
structures (5, 6).
In other embodiments, the mounting hole (3) number may
be higher or lower, depending on the loads and other mounting considerations.
The most suitable number of mounting holes (3) is two pairs: two holes at each
end of the construction element (1). In other embodiment, especially when a
narrow profile is used, all the mounting holes (3) may be positioned on a
centerline spanning over the length of the construction element (1).
Figures 5 and 6 depict one of the possible
applications of the most preferred embodiment of the invention. In this
particular application, the building construction element (1) presented by the
invention transfers the loads of the external façade plates (5) to the load
bearing structures (6) of the building through supplementary construction
elements (8, 9). The construction element (1) is riveted (4) to the
supplementary construction elements (8, 9). The riveting is done in such a way
that the heads of the rivets, having a higher surface contact area, would rest
on the face of the glass fiber construction element (1). This construction
element (1) creates a gap between the load bearing and additional structures of
the building, in this case the latter being façade plates (5). This gap
contains thermal insulation (7).
In other preferred embodiment of the invention,
depicted in Figure 2, the presented building construction element (1) is cut
from a T-shaped profile. Yet in other embodiments, depicted in Figures 3 and 4,
this construction element is cut from L-shaped and U-shaped profiles. These
profiles may be used when the horizontal loads acting on the additional
structures are higher.
In other embodiments of the invention, the
construction element (1) may have mounting planes that are parallel to the
additional (5) and/or load bearing (6) structures and/or surfaces of the
supplementary construction elements (8, 9) of the building. In these or other
embodiments, various hanging or insertable geometries may be used instead of
the screws or rivets for a mechanical mounting of the construction element (1).
In yet other embodiments, this construction element may be cemented into the
load bearing structure.
