Field of the invention
[0001] The invention relates to a heat insulation module for structures subjected to compressive
stresses, the heat insulation effect of the module consisting in interrupting the
thermal bridge after attaching a wall structure to a foundation element.
Background of the invention
[0002] At the present, different solutions offered by various manufacturers are used. In
most cases, however, the problem remains unsolved or is worked around by means of
external thermal barriers or the like.
[0003] The document
CS 154786 B1 discloses a cellular insulating building element which comprises expanded ceramsite
or flue-ash grains bonded together with a hard, foamed polyurethane resin, wherein
the resin primarily consists of polyol, such as butanediol, and further of toluene-diisocyanate,
trifluoro-chlorethylene and dimethylaniline.
[0004] The document
CS 193680 B1 discloses an insulating building element utilizing waste inorganic by-products from
chemical glass polishing, from leaching of manganese raw materials with sulphur acid
and the like. The insulating building element comprises calcium sulphate originating
from industrial wastes, defibered asbestos and hydrating binders.
[0005] Besides that, the document
CS 233065 discloses a cellular planar insulating element consisting primarily of expanded perlite
with a fibrous component, a polymeric dispersion and a hydrophobic agent.
[0006] There are also foam glass panels which, however, are too brittle. Furthermore, the
document
EP 1918471 B1 presents a panel made of a recycled plastic material based on HDPE. The main drawbacks
of the known solutions consist in their poor fire resistant properties and, in many
cases, in the use of unsuitable materials. In the course of time, such materials were
found to be harmful for the human body.
[0007] The document
EP 1 231 329 describes a load-bearing hydrophobic heat-insulating element which consists from
a supporting concrete structure having internal longitudinal cavities filled with
polystyrene. The basic module, which comprises peripheral walls, a concrete partition
wall and two cavities to be filled with polystyrene, may be multiplied along the length
of the element, thus enabling relatively long elements to be prefabricated.
[0008] The document
DE 199 42 965 describes another load-bearing hydrophobic heat-insulating element which consists
from a supporting concrete structure having internal cavities filled with polystyrene.
The cavities assume various shapes, which are typically composed of one pentagon and
two smaller squares arranged opposite the former, such geometric pattern being repeated
with alternating opposite arrangements of the pentagon and the squares.
[0009] The document
CH 689 022 describes another load-bearing hydrophobic heat-insulating element which consists
from a supporting concrete structure having internal cavities filled with polystyrene.
The cavities are formed by the openings which are arranged crosswise and interconnected
by means of small channels, the interconnected cross-like elements being deployed
in several series. One series is adjoined the other one, the opening of the latter
being offset so that all the openings are generally evenly distributed in the overall
area.
[0010] The document
DE 200 08 570 U1 describes a load-bearing hydrophobic heat-insulating element which consists from
a supporting concrete structure having internal longitudinal cavities filled with
polystyrene, the supporting concrete structure being furthermore provided with an
anchor tip which is embedded under the top face of the element and protrudes into
the layer of bricks disposed above the same.
[0011] The document
DE 295 02 704 U1 discloses a technical solution wherein concrete tubes are disposed between two concrete
panels and separated by polystyrene layers. In addition, there is a bituminous bonding
layer between the tubes and the panel.
[0012] It is the object of the invention to present a heat insulation module for structures
subjected to compressive loads, which module would be made of a lightweight, yet high-strength
material and provide optimum heat-insulating structural properties.
Summary of the invention
[0013] The above drawbacks are largely eliminated by the heat insulation module for structures
subjected to compressive stresses according to the invention, wherein the module consists
of a frame, within which a load-bearing latticed structure is arranged, the gaps between
the partitions of the module being filled with a heat-insulating material, the load-bearing
latticed structure being affixed to a foundation plate and covered by a topping panel,
all the components of the module being made of a fibreglass composite material.
[0014] In a preferred embodiment, the load-bearing latticed structure is composed of an
array of hollow prisms.
[0015] In another preferred embodiment, the load-bearing latticed structure is composed
of an array of hollow cylinders.
[0016] In yet another preferred embodiment, the array of hollow prisms or cylinders is arranged
in four regularly spaced rows, each row comprising two elements, and the heat-insulating
material is disposed both around and inside the elements.
Brief description of the drawings
[0017] The invention will be further explained with reference to the accompanying drawings,
wherein Fig. 1 shows the first embodiment of the heat-insulating module containing
the inner load-bearing latticed structure according to the invention, Fig. 2 shows
the load-bearing latticed structure without the frame in a detail view, Fig. 3 shows
the second embodiment of the heat-insulating module having the inner structural bodies
shaped as hollow prisms, the module being shown in an assembled state, and Fig. 4
shows the third embodiment of the heat-insulating module having the inner structural
bodies shaped as hollow cylinders, the module being also shown in an assembled state.
Preferred embodiment of the invention
[0018] Fig. 1 shows the heat-insulating module 1 for structures subjected to compressive
stresses, the module being depicted in an assembled state. It is apparent that the
heat-insulating wall module 1 consists of the frame 2 within which the load-bearing
latticed structure 3 is arranged.
[0019] The details of the latter are shown, including the gaps, in Fig. 2.
[0020] The gaps 4 formed between the partitions of the structure are filled with the heat-insulating
material 5 (schematically indicated). The load-bearing latticed structure 3 is affixed
to a lower foundation plate and covered by the upper topping panel 7.
[0021] With reference to the embodiment presented in Fig.3, the load-bearing latticed structure
3 is formed by the hollow prisms 3a. In the embodiment shown in Fig. 3, the same is
formed by the hollow cylinders 3b. The bodies 3a and 3b are affixed to the lower foundation
plate 6 and covered by the upper topping panel 7 (schematically indicated).
[0022] In a preferred embodiment, the load-bearing elements 3a and 3b are arranged in two
rows, each row comprising four load-bearing elements 3a and 3b. Thus, the structure
comprises eight bodies in total. Such a configuration provides optimum strength and
load-carrying capacity. The heat-insulating material is disposed both around and inside
the elements.
[0023] All the above structural components are made of a fibreglass composite material and
bonded together by means of gluing. The advantages of such a fibreglass composite
material include both high compressive strength and high bending strength.
[0024] The heat-insulating filler material is a compact thermal barrier composed of mineral
substances, such as that marketed by the manufacturing companies Orsil or Rockwool.
Filler materials like that are well known to those skilled in the art. During the
fabrication, the above described compact panel-like mass is provided with the opening
having the shape of the load-bearing bodies 3. Subsequently, the final perforated
panel is embedded into the frame.
[0025] The entire frame has 50 cm in length, 30 cm in width and 25 mm in height. The mesh
size is 50 x 50 mm. The cylindrical load-bearing bodies 3 have 50 mm in diameter.
When prismatic elements 3a are formed, the size of the lateral edges of such elements,
e.g. square ones, may be also 50 mm.
[0026] The heat insulation effect of the module according to the invention consists in interrupting
the thermal bridge after attaching a wall structure to a foundation element. This
heat-insulating wall module forms an element for carrying compressive loads, as well.
[0027] Owing to its constructional arrangement and material composition, the heat-insulating
module according to the invention is capable of carrying the entire compressive load
the building structures are subjected to.
[0028] The heat-insulating module can be modified and adapted according to the dimensions
of the particular building cladding. The behaviour of the entire element and the way
the same influences its surroundings are primarily given by the number and size of
the constituent elements used and by their material characteristics.
[0029] The overall structure in encapsulated in a heat-insulating covering and protected
by means of special fire-resistant materials.
[0030] Thus, the reduction of the heat flow achieved by means of the above element is significant.
Due to the desired fire-resistant properties, the compositions of the building claddings
used must provide the highest possible level of protection of the above element from
fire loads.
