PATENTED JAN? 1 1372 SHEET 1 UF 2 INVENTOR JARL-ERIK OHLSSON BY )(HRL U Foe (5 ll TTORNEV PATENTEU JAN? 1 m2 SHEET 2 [IF 2 ROOF CONSTRUCTIONS This invention relates to a roof construction of the type comprising interconnected sheet metal panels with preferably trapeziform corrugations, and an insulated outer roofing placed directly on said panels so as to be supported by them. The roof construction according to the present invention is characterized in that the channels formed between the outer roofing and the corrugations of the panels are connected to a ventilating system for ventilating the roof. With the use of very simple means the invention thus provides a ventilation of the roof, whereby either moisture or heat is carried away.
The invention will be more fully described in the following, reference being made to the accompanying drawings which illustrate some embodiments, chosen by way of example, of the roof construction.
In the drawings:
FIG. 1 is a transverse cross section of part of a building equipped with one embodiment of the roof construction;
FIG. 2 is a longitudinal cross section, on a greater scale, of the roof construction in connection with a duct thereof;
FIG. 3 is a view of the joint between two corrugated sheet metal panels in the roof construction;
FIG. 4 is a view of a modified embodiment of the corrugated sheet metal panels of the roof construction;
FIG. 5 is a transverse cross section of a building equipped with another embodiment of the roof construction.
The roof construction comprises interconnected corrugated sheet metal panels 1 which in the embodiments shown are supported by I-beams 2 extending longitudinally of the building. The corrugated sheet metal panels 1 support an insulated outer roofing 3 placed directly on said panels. The outer roofing 3 comprises an insulation 4 and roll roofing 5 placed thereon, but it is self-explanatory that the outer roofing may be of any other design whatever.
The corrugations of the panels 1 might be given the form of waves, but in a preferred embodiment the corrugations are trapeziform. Normally, the crests and troughs of the corrugations will be of the same size, as is seen from FIGS. 2 and 3. In certain cases, however, it may be suitable to give the crests of the corrugations a considerably smaller width than the troughs, as will appear from FIG. 4.
According to the invention, the channels 6 formed between the outer roofing 3 and the corrugations of the panels 1 are connected to a ventilating system for ventilating the roof. To avoid unnecessary losses, the joints between the individual panels 1 must be tight. A sealing strip 7 for use in the joints is shown in FIG. 3. This sealing strip 7 which is of plastics or like material, is formed as a thin band which at the two longitudinal edges merges into a tubular profile.
In the embodiment shown in FIG. 1, the channels 6 formed between the outer roofing 3 and the corrugations of the panels 1 are in communication with a duct 8 for supplying the air for the ventilation of the roof. This duct 8 in turn is in communication with the ambient air via a duct system 10 equipped with heating means 9. Said heating means 9 also comprises a fan or like apparatus for producing a certain excess pressure in the duct 8, and the excess pressure is maintained in that the duct 8 is connected via throttling means 11 to the various channels 6. The throttling means 11 will thus ensure that the air is distributed in a given manner between the channels 6.
As will be seen from FIG. 2, the throttling means 11 may consist of preferably angularly bent pipes or small apertures.
In the embodiment illustrated in FIG. 1, the channels 6 are connected at their lower ends to the duct 8 via the throttling means 1]. Otherwise, the said ends are closed by means of an L-profile or like element. On the other hand, the upper ends of the channels 6 are open so as to communicate with the interior of the building proper.
Ambient air is thus sucked in and heated, for which reason it has a low relative moisture content. At the ventilation of the roof the dried air thus carries away the moisture and at the same time prevents moist air from penetrating into the insulation 4 of the roof.
In the embodiment illustrated in FIG. 5, the channels 6 formed between the outer roofing 3 and the corrugations of the panels 1 have their upper ends (which are situated for instance at the roof peak) connected to a duct 12 for leading away the air ventilating the roof. The lower ends of the channels 6 are in communication with the interior of the building equipped with the roof construction for supplying air thereto.
In normal cases the duct 12 cooperates with a fan or like apparatus for the ventilation air. To obtain a definite distribution of the air between the various channels 6 the latter are connected via throttling means 13 to the duct 12.
The roof construction illustrated in FIG. 5 is primarily adapted to carry away the heat supplied to the roof by the sunrays indicated by the arrows 14. The air is taken from the interior of the building and, after being heated, is caused to escape through the air outlets 15 on the roof of the building.
What I claim and desire to secure by Letters Patents is:
1. A roof construction comprising interconnected sheet metal panels having trapeziform corrugations, an insulated outer roofing placed directly on said panels positioned to be supported by them wherein the insulation of said outer roofing is facing said panels and bears directly against them, channels formed between the insulation and said corrugations of said panels connected by a duct system to the ambient air outside the building with said air supplied over heating means to said channels between said insulation and said corrugations of said panels for ventilating said insulation.
2. A roof construction as claimed in claim I, wherein said duct system includes a duct cooperating with said channels and connected via throttling means to said channels so as to produce a predetermined distribution of the air between said channels.
3. A roof construction as claimed in claim 2, wherein said channels are connected with their one ends to said duct while the other ends of said channels are in communication with the interior of the building equipped with the roof construction.
