Description

       

   <EMI ID=1.1>  

  
Deze uitvinding heeft betrekking op een zelfdragend sandwichpaneel dat geschikt is voor het verwezenlijken van wandkonstrukties, doch vooral zal zulk sandwichpaneel volgens de uitvinding geschikt zijn om er daken mede te verwezenlijken, waarbij in dit laatste geval zulke zelfdragende sandwichpanelen kunnen gebruikt worden in kombinatie met om het

  
 <EMI ID=2.1> 

  
Het sandwichpaneel volgens de uitvinding dat hiervoor in aanmerking komt zal gevormd worden door een isolatielaag bijvoorbeeld uit polystyreenschuim, polyurethaanschuim, glasvezels en dergelijke, waarbij deze isolatielaag aan iedere zijde

  
 <EMI ID=3.1> 

  
werende spaanplaat en waarbij deze drie delen bij voorkeur door

  
 <EMI ID=4.1> 

  
 <EMI ID=5.1> 

  
 <EMI ID=6.1> 

  
 <EMI ID=7.1> 

  
dat verwezenlijkt is door middel van gordingen kan men voor een schuin dak de sandwichpanelen, van goot tot nok, direkt op de gordingen aanbrengen. In het geval van een spantendak worden de sandwichpanelen echter hetzij dwars op de spanten geplaatst, indien men te maken heeft met gewone spanten, met andere woorden

  
 <EMI ID=8.1> 

  
4 cm, hetzij van goot tot nok worden geplaatst, indien men te maken heeft met dikke spanten, bijvoorbeeld van de orde van

  
8 cm. Op deze wijze verkrijgt men steeds een vlugge en gemakkelijke montage waardoor de kostprijs van de dakkonstruktie zeer gunstig wordt beïnvloed, waarbij in het geval van een gordingdak, tevens een besparing op de dakkonstruktie zelf wordt verkregen en waarbij in alle gevallen automatisch een isolerende dakbedekking wordt gevormd. 

  
Zulke zelfdragende sandwichpanelen kunnen vanzelfsprekend in om het even welke afmetingen worden uitgevoerd, waarbij de afmetingen van de samenstellende delen ten opzichte van elkaar eveneens kunnen gewijzigd worden in verhouding van de gestelde eisen en dit meer speciaal in verband met de eisen op het ge-

  
 <EMI ID=9.1> 

  
eisen met betrekking tot de gewenste draagkracht van het sandwichpaneel en de overspanningsmogelijkheden.

  
Zulk sandwichpaneel zal aan de bovenzijde nog voorzien worden van latten die volgens de dakhelling gericht zijn en

  
 <EMI ID=10.1> 

  
één en ander zodanig dat er tussen de sandwichpanelen en de dakbedekking een bewegende luchtlaag wordt gevormd, zodat deze ruimte s teeds gedroogd wordt en waarbij deze ruimte dienstig is

  
 <EMI ID=11.1> 

  
 <EMI ID=12.1> 

  
De voornoemde latten zullen bij voorkeur minstens behandeld worden met een vocht- en schimmelwerend produkt.

  
Nog een ander voordeel van de sandwichpanelen volgens

  
de uitvinding is dat het soortelijk gewicht ervan zeer laag

  
kan zijn, namelijk van de orde van 8 a 9 kg/m<2>, wat eveneens een zeer gunstige terugslag heeft op de kostprijs van de eigenlijke draagkonstruktie, respektievelijk dakkonstruktie.

  
Een sandwichpaneel volgens de uitvinding vormt dus tegelijkertijd een geschikt isolatie- en weerstandspaneel waarop

  
in de meeste gevallen de dakbedekking of dergelijke, in het algemeen door tussenkomst van panlatten of dergelijke, recht-  streeks kan aangebracht worden. 

  
Daar de in het algemeen, op gebied van weerstand,  zwakke isolatielaag volledig en doeltreffend ingesloten zit 

  
 <EMI ID=13.1> 

  
 <EMI ID=14.1> 

  
dat deze isolatielaag volledig beschermd wordt tegen om het   <EMI ID=15.1> 

  
treffend en blijvend gegarandeerd wordt. 

  
In een bijzondere uitvoering zullen minstens twee tegen- 

  
 <EMI ID=16.1> 

  
ten einde de panelen met elkaar te verbinden waarbij, in het ge-  val van een gordingdak, deze getande randen bij voorkeur vol-  gens de dakhelling zullen voorzien worden, terwijl bij een span-  tendak de getande randen bij voorkeur dwars op of volgens de

In de uitvoering volgens de figuren 4 en 5 waar het 

  
 <EMI ID=28.1> 



   <EMI ID = 1.1>

  
This invention relates to a self-supporting sandwich panel which is suitable for realizing wall constructions, but in particular such a sandwich panel according to the invention will be suitable for the realization of roofs, wherein in the latter case such self-supporting sandwich panels can be used in combination with

  
 <EMI ID = 2.1>

  
The sandwich panel according to the invention that is eligible for this will be formed by an insulating layer, for example of polystyrene foam, polyurethane foam, glass fibers and the like, with this insulating layer on each side

  
 <EMI ID = 3.1>

  
resistant chipboard and with these three parts preferably through

  
 <EMI ID = 4.1>

  
 <EMI ID = 5.1>

  
 <EMI ID = 6.1>

  
 <EMI ID = 7.1>

  
this is achieved by means of purlins, for a sloping roof, the sandwich panels can be fitted directly on the purlins from gutter to ridge. In the case of a rafter roof, however, the sandwich panels are either placed transversely to the rafters, if one is dealing with ordinary rafters, in other words

  
 <EMI ID = 8.1>

  
4 cm, or be placed from gutter to ridge, if one is dealing with thick trusses, for example of the order of

  
8 cm. In this way one always obtains a quick and easy installation, whereby the cost price of the roof construction is very favorably influenced, whereby in the case of a purlin roof, a saving is also obtained on the roof construction itself and whereby in all cases an insulating roof covering is automatically formed. .

  
Such self-supporting sandwich panels can of course be designed in any dimensions, while the dimensions of the constituent parts can also be changed relative to each other in proportion to the requirements set, and this more especially in connection with the requirements on the product.

  
 <EMI ID = 9.1>

  
requirements with regard to the desired load-bearing capacity of the sandwich panel and the span options.

  
Such a sandwich panel will still be provided with battens on the top that are oriented according to the roof pitch and

  
 <EMI ID = 10.1>

  
this in such a way that a moving air layer is formed between the sandwich panels and the roof covering, so that this space is always dried and this space is useful

  
 <EMI ID = 11.1>

  
 <EMI ID = 12.1>

  
The aforementioned slats will preferably be treated at least with a moisture and fungicidal product.

  
Yet another advantage of the sandwich panels according to

  
the invention is that its specific weight is very low

  
can be, namely of the order of 8 to 9 kg / m <2>, which also has a very favorable impact on the cost price of the actual supporting construction and roof construction, respectively.

  
Thus, a sandwich panel according to the invention simultaneously forms a suitable insulation and resistance panel on which

  
in most cases the roof covering or the like, in general by means of battens or the like, can be applied directly.

  
Since the generally weak insulating layer is completely and effectively contained in terms of resistance

  
 <EMI ID = 13.1>

  
 <EMI ID = 14.1>

  
that this insulation layer is fully protected against any of the <EMI ID = 15.1>

  
striking and permanently guaranteed.

  
In a special version, at least two counter-

in order to join the panels together wherein, in the case of a purlin roof, these serrated edges will preferably be provided according to the pitch of the roof, while in the case of a tensioned roof the serrated edges are preferably transverse to or along the

 <EMI ID = 18.1>

  
To better demonstrate the invention, some embodiments are described below, by way of example without any limiting character, with reference to the accompanying drawings, in which: Figure 1 shows a perspective view of a sandwich panel according to the. invention? figure 2 represents a cross-section according to line II-II in <EMI ID = 19.1> figure 5 represents a cross-section according to line V-V in figure 4, but for an embodiment variant; figure 6 schematically represents a transverse section through an ordinary rafter roof provided with sandwich panels according to the invention:
figure 7 represents the part indicated by F7 in figure 6 to a larger scale; figure 8 schematically represents a transverse section through a rafter roof, whereby the panels according to the invention are laid from gutter to ridge;
