Description

Prefabricated facade element and a proceeding for making the same
The present invention concerns a
prefabricated facade element, which is formed of at least one sheet consisting of hardened material as well as an insulating sheet situated along said sheet and made of thermally insulating and pervious insulation material, and an outer surface layer.
The present facade element according to the present invention intends to solve a number of problems relating to facade elements and then primarily that a thermally insulating facade element is obtained that has the property of also forming a drainage channel system inside the proper thermally insulating facade element .
Said object is achieved by means of a prefabricated facade element of the above-mentioned type, which essentially is characterized in that the insulant consists of united thermally insulating bodies having a drainage channel system formed between the same, that said layered insulant is formed of glued-together EPS balls or other uniting thermally bodies in such a way that there arises a drainage channel system between said EPS balls or other thermal bodies, and that said formed insulant sheet is joined with the sheet consisting of hardened material by encasing as well as complete and/or partial enclosure of abutting portions of said insulating bodies, and arranged to harden around the bodies in the insulant sheet . The present invention also concerns a proceeding for making prefabricated facade elements that are formed of an outer and/or an internal sheet consisting of hardening material as well as an insulating sheet situated on the outside of said sheet and made of
thermally insulating and pervious insulation material, and an outer surface layer.
The manufacture of a said prefabricated facade element will be easy to carry out and several steps and parts included therein are avoided, which otherwise are utilized in the manufacture of conventional such prefabricated facade elements .
Said object is achieved by a proceeding of the above-mentioned type, which essentially is
characterized in that at least one of said sheets
consisting of hardening materials is cast, wherein, in connection with the casting, the adjacent thermally insulating sheet, which consists of united thermally insulating bodies having a channel system formed between the same, is joined so that the surface layer of the hardened material adheres to one surface layer of said insulating sheet, wherein the hardened material attaches to said thermally insulating bodies of said insulating sheet in connection with the hardening of the material, viz. that, at the same time as an internally load-carrying sheet is cast and before said sheet has hardened, there is applied a layer of EPS balls or other insulating bodies and glue or another adhesion agent for the gluing together of said EPS balls or bodies to each other on the sheet material so that the surface layer of the sheet surrounds EPS balls or other insulating bodies between which a drainage channel system is formed and sticks to the insulating sheet glued- together thereby. The invention is described below in the form of a preferred embodiment example, reference being made to the accompanying drawings, in which
Fig. 1 schematically shows a cross- sectional view of a facade element according to the invention,
Fig. 2 schematically shows a manufacturing proceeding of a facade element according to the invention,
Fig. 3 shows a prefabricated facade element in perspective, and
Figs . 4 and 5 show the surface layer of a thermally insulating sheet with water flowing through and in dry state, respectively.
The construction known by US 4,562,109 A comprises a protection against cracking of concrete walls (1) . A layer (23) of glued balls, e.g. expanded
polystyrene balls, is attached on the concrete wall (1) , when the wall is upright. A surface layer (5) is then applied to the wall outside the glued-on layer (2, 3), e.g. a paint coat. Then, an insulated wall without air gap is formed. A tight wall. The balls are not at all for insulation purposes primarily, even if a thermal
insulation is obtained thereby. See column 4, line 21-40.
By FR 2 330 822 Al, a building board is previously known, which comprises an embedded cellular plastic board (4) consisting of expanded polystyrene and surrounding gypsum or cement coating (11, 12). By means of trichloroethylene , the surfaces (5, 6) of said cellular plastic board (4) are treated so that spherical cavities (7, 8) are formed thereat before it is coated together with liquid gypsum/cement material (11, 12) . The cellular plastic board (4) is not liquid-permeable and pervious and the proceeding is in addition complicated since it requires a process of many steps and is not so
environmental-friendly when the cellular plastic balls are eaten away by trichloroethylene . Such a building panel has not the properties of a load-carrying concrete wall so that it can be used as thermal facade load-carrying but it is solely utilized as thermal facade panel or as sound- absorbing and thermal partition wall in building.
The present invention instead focuses on an aspect of the construction wherein there are added unique properties that radically lift a conventional construction so that the manufacture process becomes more rational, the final result gets improved properties and furthermore requires less resource extraction from nature.
According to the present invention, the balls, etc. are surrounded in the pervious and thermally insulating intermediate layer II completely and/or
partially directly when the sheet is lowered into the hardening mixture, etc. No treatment of the surfaces of said sheet needs to be made to provide reliable retention between the load-carrying material layer III and said material layer II.
A thus intended facade element 100
consists of three material layers I, II, and III in a way corresponding to conventional solutions today. In the present product, however, the second and the third layer are replaced by new innovative materials to afford the production process and the finished product unique
advantages .
The invention concerns a prefabricated facade element 100 in the form of a thermally insulated wall with surface layers farthest out. Innermost, a load- carrying framework III may be arranged of, e.g., concrete. The outer layer (I) is the front side of the wall:
Material layer I - reinforcement-free cladding
The surface layer consists of a hardening material, such as, for instance, fibre-reinforced material I or a
material having a polymer matrix and that can be dyed and given a surface structure already in the factory. Since it is coloured throughout, colour fastness with good
mechanical resistance is achieved. Since the construction is not in need of transverse reinforcement through the insulation, this material I does not have to be
dimensioned for the fixing of this reinforcement and can thereby be made thinner, and cracks, etc. in the surface can be reduced by admixture of fibre reinforcement.
The intermediate layer II is a thermal insulation:
Material layer II - pervious and preferably fire protected insulation
This unique insulation (II) , which
consists of glued- together EPS balls or of other united thermal bodies of corresponding or another similar
material so that a drainage channel system between said EPS balls or other thermal united bodies arises, is also one of the main components. The insulation II is applied directly to the material layer I and catches in the same when the material layer I hardens during the manufacture process. The insulation (II) can transfer the requisite wind load, etc. that the facade is subjected to, without the need of transverse reinforcement through the layer as is the case today.
Material layer III - structurally supporting interior load-carrying sheet of, e.g., reinforced concrete or of another suitable hardening material. This part of the construction is
conventional, and is the supporting part of the wall structure that is joined with the frame of the building. This material III is, for instance, manufactured using a normal proceeding for prefabricated concrete elements.
Normally, said sheet III may, e.g., be 3 m high (one storey), up to approx. 5-6 m long and 0,2-0,3 m thick.
The proceeding for making facade elements in factory now becomes uniquely simple.
The innovative design consists of a prefabricated facade element 100, which directly can replace the type that is common today. This facade element 100 can be manufactured in the same way as conventional facades, i.e., lying down on a table in the factory, and is raised up when all the material layers are applied and co-hardened to a sufficient strength. Further hardening may, e.g., take place standing in stands in the factory before they are delivered by lorry or truck to the working site where they are mounted by means of a crane or in another way.
The innovation of this facade element consists partly in that the insulation II by its structure can guarantee satisfactory adhesion and load anchorage between the inner structurally supporting sheet III and the outer facade sheet I without through anchorage. Today, mineral wool insulation is normally used. This type of insulation cannot alone carry the forces that arise on the facade but needs to be transversely reinforced. It is true that normal expanded plastic insulation can carry forces without transverse reinforcement, but often gets defects in the adhesion to the supporting concrete sheet III that arise during the manufacturing phase. By said insulation II, these defects do not arise, at the same time as the carrying capacity meets the required values.
The second part of the innovation means that on top of the insulation II in the form, a hardening material is directly applied, such as, for instance, a fibre-reinforced material with the polymer matrix I in flowing state, which is allowed to harden. This material I may, but does not have to, contain a mineral base (e.g. cement) . The material may be coloured throughout or patterned by tools or templates so that the surface gets the desired appearance. Normally, this material previously had to be strengthened by a welded mesh reinforcement, which requires a certain cover because of anchorage and durability, and thereby the layer gets a significant and annoying thickness.
Thanks to the pervious insulation II having an open pore system, this construction will be two- stage tightened and pervious, which is a considerable improvement of the moisture safety.
A pref bricated facade element 100, which is formed of at least one sheet III consisting of hardened material such as concrete or another hardening material as well as an insulating sheet II situated along said sheet III and made of thermally insulating and pervious
insulation material and an outer surface layer I comprises an insulating sheet II wherein the insulant consists of united thermally insulating bodies having a drainage channel system formed between the same. Furthermore, said formed insulant sheet II is joined with the load-carrying sheet III consisting of hardened material by encasing as well as enclosure of abutting portions of said insulating bodies . Said layered insulant is formed of glued- together or in another way joined EPS balls or other bodies of thermally insulating material in such a way that there arises a drainage channel system between said EPS balls, etc. See Figs. 4 and 5 which show the draining function when water is poured on the surface of the sheet and the water can pass transversely all through the sheet. A said internal sheet III consists of reinforced concrete or of fibre-reinforced material, which is arranged to harden around the bodies in the insulant sheet II or be stuck together by means of another hardening adhesion agent, such as, e.g., glue.
Said outer surface layer I forms the front surface and suitably consists of a fibre-reinforced material that preferably is dyed and/or exhibits a desired surface structure. Alternatively, a material having a polymer matrix or a concrete sheet may be cast or in another way be attached on the insulant sheet II.
A specified proceeding for making
pref bricated facade element 100, which is formed of an outer and/or an internal sheet I; III consisting of
hardening material as well as an insulating sheet II situated on the outside of said sheet and made of
thermally insulating and pervious insulation material, and an outer surface layer, means that at least one of said reinforced sheets I, III consisting of hardening materials is cast, wherein, in connection with the casting, the adjacent thermally insulating sheet II, which consists of united thermally insulating bodies having a channel system formed between the same, is joined so that the surface layer of the hardened material adheres to one surface layer of said insulating sheet, wherein the hardened material attaches to said thermally insulating bodies of said insulating sheet II in connection with the hardening of the material .
In that connection, the prefabricated thermally insulating sheet II, which is formed of e.g., glued-together EPS balls, is joined with hardening
material consisting of concrete material or another fibre- reinforced material or a material having a polymer matrix. At the same time as an internal reinforced concrete sheet III is cast and before the concrete has hardened or after the hardening of the concrete, there is applied a layer of EPS balls or other insulating bodies and glue or another adhesion agent for the gluing together of said EPS balls or bodies, etc. to each other on the concrete material so that the surface layer of the concrete material surrounds EPS balls or other insulating bodies situated farthest out of said thermally insulating sheet II and sticks to the insulating sheet II glued-together thereby or after, e.g., agglutination with the hardened concrete sheet III.
In connection with, or after the
attachment of the insulating sheet II to the internal preferably reinforced concrete sheet III or load-carrying sheet III manufactured of another fibre reinforced
hardening material, there is applied an outer
reinforcement-free cladding I consisting of fibre- reinforced material or a material having a polymer matrix and which preferably is dyed and that is given the desired surface structure of said cladding I in connection with the manufacture of the load-carrying wall element or it is proceeded in the reverse order by first casting the cladding.
A concrete sheet is accordingly attached to at least one side of the insulant layer sheet II. Naturally, the invention is not limited to the embodiments described above and shown in the
accompanying drawings. Modifications are feasible, particularly as for the nature of the different parts, or by using an equivalent technique, without departing from the protection area of the invention, such as it is defined in the claims.

connection with the hardening of the agent, viz. that after a said internal load-carrying sheet (III) is cast and after said sheet (III) has hardened, there is applied a layer of EPS balls or other insulating bodies and glue or another adhesion agent for the gluing together of said EPS balls or bodies to each other and to the cast load- carrying sheet III so that the surface layer of the sheet (III) connects to said EPS balls or other insulating bodies between which a drainage channel system is formed and sticks to the insulating sheet (II) glued-together thereby, whereupon the outer surface layer (I) of the facade element is cast on the outside of the insulating sheet (II) .
