Definitions
- the present invention relates to a roof structure according to the preamble of claim 1, which rafters and arranged on the rafters the outer and Inside forming plates is formed with the formation of surface elements.
- the airtightness is due to the Piercing the building envelope with purlins and rafters is problematic. Because a Passing through the gap or joints and scratches does not just mean entering cold Outside air into the house, but also an escape of warm room air elsewhere. The air humidity that is carried along can pass through condense the gap in the roof structure and causes considerable structural damage to lead.
- This can also cause cracks on the circumference of the rafters and purlins arise which the air exchange between the environment and the inside of the Building further favor.
- the energy balance of the building due to the Gap and the gap width widening with time adversely affected because it is too a high heat transfer from the heated interior of the building to the outside.
- the rafters and purlins are compared to the usual today Insulation materials represent a cold bridge, since the thermal conductivity of wood is very high is higher than the thermal conductivity of the insulation materials. Due to the contact of the Rafters and purlins with the ambient air over their almost entire circumference the rafters and purlins are strongly cooled, with a constant heat transfer from the heated interior to the outside due to the thermal conductivity of the wood. As a result, it occurs despite good specific thermal insulation of the roof area and the outer wall through the outwardly projecting rafters and purlins to a relative high heat loss from the heated interior to the outside.
- WO92 / 21833 is a roof structure with surface elements become known, the surface elements of rafters and on the rafters arranged plates are formed, which respectively the outside and inside of the Form surface element.
- the surface elements also protrude in the area of the verge and / or the eaves following the outer wall of the building to the outside.
- An advantage of the invention with the features of claim 1 can be seen in in that there are no rafters or purlins in the area of the eaves or verge protrude outwards, accordingly no gap between the rafters or purlins and the outer wall of the building is created.
- the gap between the the rafters or purlins and the outer wall to a minimum, with none aging-related problems with the gap may occur.
- the through the cantilever over the outer wall outstanding space between the outer Plate and the inner plate can be used for insulation.
- the appearance of the roof structure also has an effect light and aesthetic thanks to the sloping cantilever.
- the cantilever of the surface elements extends at an angle of 35 ° to 55 °, it is also achieved that the roof on the one hand protrudes sufficiently beyond the outer wall and on the other hand has sufficient static strength of the cantilever so that there are no deformities or Damage to the roof structure due to a roof load occurs. Further advantageous embodiments of the invention are the subject of the dependent claims.
- Panel elements in modular design can be placed on the roof.
- the surface elements can be industrially prefabricated inexpensively, one complex assembly of the cantilever in the area of the eaves or verge on site falls off at roof height.
- the prefabricated self-supporting surface element with cantilever is also simple to manufacture and edit, the thickness of the cover plate of the size of the Cantilever and the local roof load depends on the static Requirements are measured.
- the training according to claim 7 has the advantage that the Roof area protrudes beyond the cantilever to be sufficient for cooling in summer Provide shade and the outside walls of the building especially in winter To protect rain and snow and the resulting strong cooling.
- Fig. 1 is an advantageous embodiment of the roof structure according to the Present invention shown in the area of the verge, which on a Outer wall 20 is attached.
- the roof structure is made of rafters 12 and on the Rafters 12 arranged, forming the outside and inside, plates 14, 16 below Formation of surface elements 11 constructed. Between the one forming the outside Plate 16 and the plate 14 forming the inside is one in the area of verge 30 Cover plate 3 at an angle of essentially 45 degrees to the roof surface 10 inclined, which a projection 5 of the surface elements 11 according to the present Invention forms.
- the cover plate 3 is on the plate 16 and the outside forming the plate 14 forming the inside is attached flush.
- the surface elements 11 can are industrially prefabricated, with an insulating layer 19 between which the Outside plate 16 and the inside plate 14 is attached.
- This roof construction made of prefabricated self-supporting surface elements 11 placed on the outer wall of the building by a crane.
- FIG. 2 shows the roof structure of FIG. 1 in the area of the eaves 40.
- the surface elements 11 form the self-supporting prefabricated roof structure, whereby on the plate forming the outside 16 roof shingles 18 to form the Roof surface 13 are attached. Between the plate 16 and the plate 14 forming the inside runs in the area of the eaves 40 Cover plate 3 at an angle of essentially 45 degrees to the roof surface 10 inclined pointed outwards towards the roof surface 13. The cover plate 3 thus forms a projection 5 of the surface elements 11.
