Description
BUILDING SYSTEM FOR EXTERNAL WALLS OF BUILDINGS
The present invention refers to a building system for external walls of buildings, composed of prefabricated panels mostly made of wood with high heat insulation and reduced thickness.
The need of making building envelopes with high heat insulation performances, in terms of protection of the internal living space, both in winter, from cold, and in summer, from heat - has finally become a priority and is often compulsory in legal standards. The increase of the building envelope efficiency generates a strong reduction of the energy needs for air conditioning, and a comfort improvement . However, known building techniques tend to reach the objective not with different and adequate arrangements, but, in the majority of cases, by adding to the usual manufactured products, through stratification, further materials capable of obtaining the new performance parameters, with the following increase of times, of costs and of the ecologic weight of
the buildings.
Building prefabrication systems where wood is prevailing have evolved in recent years, both in technologic terms and for obtained market shares. The increase of quality performance in terms of energy efficiency, environmental sustainability and living comfort, required by standards in force and by market demands, have pointed out the positive features of wooden building systems.
Within such systems and as regards the construction of external walls of buildings, currently techniques are used, which can be summarised into the following major types:
1) "XIam type"
· prefabricated panels made of multi-layer hard wood to layers glued with blades which are comb-joined, smoothed and glued, with variable sizes. Integrative insulating materials are placed in situ on the external side. The panels can be used as walls or as attics.
Important features: optimum structural behaviour, high weight, high cost.
2) With carrier framework
• walls made upon installation, assembling the necessary layers onto a carrier frame of
vertical risers and horizontal cross members (made of hard wood or lamellar wood) , with variable centre distance. Insulating material is placed in the frame space. External and internal padding are obtained with panels made of multi-layer wood or glued scales, nailed to risers to guarantee their stiffening. Further layers are then added: outside, a water-proof membrane, possibly a further insulating layer, and a finishing layer. On the internal side, a steam barrier and a padding and finishing panel are made. For placing channels and plant terminals, it is necessary to add a panel creating an empty chamber. Important features: good insulating behaviour, low thermal inertia, low mechanical surface resistance, long assembling time.
With carrier framework/wall
• carrier walls exploit the structural cooperation between primary frame and drum- type prefabricated padding panels, which are made with their own frame having a small section and narrow pitch, braced and stiffened through plaques with slabs of the OSB, LVL, gypsum-fibre type or other. The space between
the primary frame risers is further filled with slabs made of insulating material, then padded with a wooden panel, which provides the support for laying plant channels. A last padding and finishing layer ends the stratography . The facade coating is applied outside the prefabricated panels upon installation. Important features: similar to the previous ones, with a reduction of the resisting section of the main structural framework .
US-A1-2012/144763 discloses a building system without waterproof air chambers between its insulating layer and its composite panel, or a building system having a single waterproof air chamber, but without using an insulating layer.
GB-A-2 451 183 discloses a building system which has no waterproof air chamber, since it does not disclose any supporting structure which should define them.
Object of the present invention is solving the above prior art problems, by providing a building system for external walls of buildings composed of high-performance wall panels, with small section, completely prefabricated at industrial level, which
can be easily handled and quickly dry-assembled.
The advantages are several and can be summarised with a strong reduction of building costs, both economic and ecologic ones - and of costs for energetically managing the building. This with an increase of living quality and comfort. Such advantages mainly derive from two factors: decrease of logistics, transport and yard burdens; decrease of building times in a yard, due to the sharp reduction of the number of operations and the absence of wait times (assembly wholly occurs dry) .
It is immediate to infer, from this global perspective, that also the environmental burden is strongly reduced. This solution therefore has advantages also from the ecologic sustainability point of view.
The above and other objects and advantages of the invention, as will appear from the following description, are obtained with a building system as claimed in claim 1. Preferred embodiments and non- trivial variations of the present invention are the subject matter of the dependent claims.
It is intended that all enclosed claims are an integral part of the present description.
The present invention will be better described
by some preferred embodiments thereof, provided as a non-limiting example, with reference to the enclosed drawings, in which:
- Figure 1 is a schematic top sectional view of a first embodiment of a building system according to the present invention;
- Figure 2 is a schematic top sectional view of a second embodiment of the building system according to the present invention;
- Figure 3 is a schematic top sectional view of the first embodiment of the building system of the invention used with an external coating with vented facade;
- Figure 4 is a schematic top sectional view of the first embodiment of the building system of the invention used with an external coating with self-carrier stones; and
- Figure 5 is an exploded perspective view of the first embodiment of the building system of the invention .
With reference to the Figures, a preferred embodiment of the building system of the present invention is shown and described. It will be immediately obvious that numerous variations and
modifications (for example related to shape, sizes, arrangements and parts with equivalent functionality) can be made to what is described, without departing from the scope of the invention as appears from the enclosed claims.
The designed arrangement deals with the improvement of energy performances of prefabricated wooden panels for external walls, suitable in the building sector for different use destinations: residential, commercial, industrial. The objective is making panels with very high heat insulation, small thickness (anyway lower than the thickness of existing panels with the same performance) and reduced weight. Performance, economic and ecologic advantages immediately derive therefrom.
Such panels are devised to be used both in a new building, and in energy re-qualification of existing buildings.
High insulation and small thickness generate a high energy efficiency of the building envelope with optimum living comfort, associated with a reduced consumption of useful space.
A total industrial prefabrication of the new panels, small weight and overall sizes, assembly quickness - determine a strong reduction of
transport and laying times and costs; consequently, there is a reduction of the building environmental weight with respect to other known techniques.
Requirements of lightweight and mechanical resistance with respect to section size, and of high insulation - are satisfied by associating materials and semi-finished works with high performance values, industrially assembled to obtain a building system composed of a composite multi-layer panel P, which gives a synergic value to the physical-mechanical qualities of the components, with respect to required performances.
With reference to Figure 1, the main components, and their features, are synthetically described below, for making the building system P of the invention for building envelopes, in particular for external walls, roofs and attics of buildings; such building system P is composed, according to a first preferred, but not limiting, embodiment, of a composite multi-layer panel, which comprises :
• at least one composite panel of the sandwich type, equipped with two layers 1 made integral through gluing, each one of such layers 1 being composed of multi-layer wood subjected
to phenol gluing (in particular with resins) and of at least one core 2 made of high- density insulating material with variable thickness, placed inside the two layers 1; this arrangement provides the composite panel with features of high resistance to humidity, loads and flexure;
at least one thin multi-layer heat-reflecting insulating layer 3, preferably composed of multiple layers of which: two metal-coated coating films 3a, 3b with reinforcing grid 3c, layers of foam 3d alternated with reflecting films 3e, layers of natural insulation 3f (made of sheep wool or the like) , all suitably assembled through thermal gluing. The thermo- reflecting facing 3 is made continuous by applying a specific adhesive band in its junctions;
at least one supporting structure 4 placed in contact with the two sides of the thin heat- reflecting insulating layer 3, composed of a framework of wooden listels, with adequate thicknesses as to create a waterproof air chamber 5 between the insulating layer 3 and the composite panel 1, and an air layer
circulating between the insulating layer 3 and at least one surface finishing panel 6 placed from the opposite side of the composite panel 1 with respect to the insulating layer 3.
Figure 2 shows the building system of the invention in a second embodiment thereof, different from the first one in the supporting structure 4 which is placed in contact only with a side of the thin heat-reflecting insulating layer 3.
The above-described composite system P is adapted to be completed with multiple types of external and internal finishing facing. As an example, some of them are cited, among the most widespread ones:
• external facing: of the vented type (as shown in Figure 3) , made of slabs of various materials fastened to dedicated metal under- structures 8 supported by suitable structural risers 7, whose sizes depend on the static dimensioning of the construction to be made; or of the traditional type made of self- carrier masonry 8' (Figure 4), supported by suitable structural risers 7, whose sizes depend on the static dimensioning of the construction to be made, wherein the composite
panel made of phenol wood can however be used as visible, without further coatings
• internal facing: made of simple or double slabs made of cardboard-coated gypsum, silicate gypsum, wooden panels or wooden staves, or any other suitable slab (not shown) .
In case of recovery of existing buildings, the prefabricated panel P is suitable to be laid as internal counter-wall with respect to original masonry:
• for mono-layer masonry made of stone or carrier tile quoins, it can be internally assembled, wholly replacing the protective function of the pre-existing wall. In case of buildings with historical value, this arrangement allows preserving the original appearance and the original factory nature, and simultaneously the complete energy re- qualification.
• For masonry with double facing and empty caisson, made of tiles or mixed, the prefabricated panel P can replace the internal facing, energetically re-qualifying the
building without modifying the room sizes.
The described panels can be used for integrating electric plants, channels and shunt boxes and terminal-carrier boxes. They can be either pre-assembled in a workshop, or assembled in a yard, before laying the internal finishing panels .
As regards the technical features of the building system P of the invention, the above described panel allows reaching a reduced value of final heat transmittance, due above all to the integration of the heat-reflecting layer on its internal side.
The heat-reflecting material has very small thicknesses, low heat conductivity values and is characterised by its reflecting and low emitting operation. These latter ones are major aspects which allow increasing the energy performance of the whole system both in winter, and in summer, and ensure its application in the different climatic areas and the reduction of the energy needs for heating and cooling.
Moreover, the described system:
• does without the presence of thermal bridges, since the thermal insulation continuity is
guaranteed on the panel intrados together with joint sealing (banding);
the global panel stratography has high thermal-hygrometric features without interstice or surface condensation phenomena; the high mechanical resistance of the composite gives the panel optimum resistance features with respect to its own weight, much greater than those of known wooden wall systems ;
the panel can be industrially pre-fabricated, with working qualities which cannot be obtained by an artisan or in a yard;
due to its small weight and thickness, to its planarity - it can be easily stored, transported, moved even manually, and quickly assembled, needing only the installation integrations of its finishing facing.
