Definitions
- the invention relates to a building roof with a Substructure made of plate-shaped composite material such as Precast concrete parts, one covering the building composite material and material layer attached to the composite building material and roofing elements such as roof tiles that are attached to the material layer are attached and on a sub-roof membrane.
- Precast elements are used as composite building material, that between the top of a house wall and the Ridge run.
- the precast concrete is processed that they can be arranged to overlap each other. So far, there has been a welding track on the composite building material applied.
- Roof covering elements such as roof tiles are used on the welding track attached.
- the side facing the roof tiles is the Welding track, for example, is sanded or has slate chips on.
- roof tiles are fastened to the welding track with mortar, each roof tile individually or just every fourth or fifth roof tiles connected to the welding track become.
- the weld path is usually 4 to 6 mm thick, so that it has a basis weight in the range from 4 to 6 kg / m 2 .
- the invention is based on the object to create a building roof of the type mentioned at which while ensuring the functions of the known used welding path a water vapor permeability of Building roofs are provided in total, and a sub-roof membrane to indicate for this.
- This task is the one mentioned in the building roof Kind solved in that the material layer as a multilayer, diffusion-open web is formed, the one side as a primer for a fastening material such as Mortar is formed with which the roofing elements can be attached to the web.
- the web can be attached to the composite building material panels in any manner are attached, for example by mechanical Mounting. It is also possible that the web at Pouring precast concrete as an example of the plate-shaped Building composite material on a surface of the precast concrete elements is applied. Act on this surface it makes sense to be one of the two large side surfaces of the precast concrete parts.
- the web can be constructed in three layers, the outer ones Layers of a woven or non-woven layer, that for both water vapor and liquid water is permeable, and the inner layer of a layer, permeable to water vapor and liquid water is impermeable to be formed.
- the three-layer structure results mainly from that the inner layer has an equivalent air layer thickness of less than 0.3 m.
- Possible materials for the inner layer are polyurethanes, acrylates, filled, stretched polyolefins. Layers of such materials have the property that they can hardly be mechanically loaded are. Because of this, a backing layer is required so that the mechanical strength of the diffusion open, inner layer is guaranteed. From these There are two layers of requirements.
- the third Layer which is one of the outer layers, must meet the requirements for the formation of a primer for mortar, for example.
- the equivalent air layer thickness of the outer layers is small compared to the diffusion equivalent air layer thickness of the inner layer.
- the latter is preferably in the range from 0.02 to 0.06 m.
- the basis weight of the web can be in the range from 100 g to 500 g / m 2 . In principle, the lowest possible basis weight of the web is to be regarded as cheap. As a boundary condition, however, it should be noted that in the three-layer structure of the web, the backing layer has a sufficient thickness to reinforce the diffusion-open layer and the layer assigned to the roofing elements has a sufficient thickness for an adhesive base.
- the layer assigned to the roof covering elements can preferably be formed from a polypropylene or polyester spunbonded nonwoven with a basis weight in the range from 30 to 150 g / m 2 .
- a polyolefin material is preferred from the materials for the diffusion-open layer already listed above.
- the permeable layer can have a basis weight in the range from 10 to 200 g / m 2 .
- the focus in the formation of the diffusion-open layer is solely on the provision of the desired diffusion-equivalent air layer thickness (s d value).
- the outer layer serving as the carrier layer in the embodiment with a three-layer structure of the web can be formed from a polypropylene or polyester spunbonded fabric with a basis weight in the range from 60 g to 160 g / m 2 .
- the backing layer is preferred as a primer for a fastener like an adhesive especially liquid glue trained to attach the web to the composite building material.
- a fastener like an adhesive especially liquid glue trained to attach the web to the composite building material.
- the glue should be given the area of use in the roof area a lifespan of several decades to have.
- Glue should be applied very thinly. Besides, is a point or preferably striped use of the adhesive advantageous. It must be ensured that the adhesive does not have the effect of the diffusion-open layer impaired, i.e. the glue must be used that the diffusion openness of the building roof mainly is determined by the layer that is open to diffusion.
- the thickness of the web can range between 0.4 and 1.5 mm lie, so that the web overall much lighter than that previously used in the prior art Sheeting.
- An embodiment of a building roof according to the invention is structured from the inside out as follows.
- the inside of the building roof is made of precast concrete formed, each abutting on a roof side are arranged and from the top of a house wall to the top of the roof.
- a polymer-based adhesive is applied to the outside in strips applied.
- a sub-roof membrane is made up of two outer polypropylene spunbond and an inner, diffusion-open Polypropylene layer exists on the precast concrete parts glued.
- the layer which is open to diffusion it is in particular a filled and stretched polypropylene film act.
- the fleece layer facing the precast concrete has a basis weight of 80 g / mm 2 .
- the polypropylene layer has an s D value in the range from 0.02 to 0.06.
- the non-woven layer made of a polypropylene spunbond facing away from the precast concrete parts has a basis weight of 80 g / m 2 .
- the non-woven layer made of a polypropylene spunbond facing away from the precast concrete parts has a weight per unit area of 120 g / m 2 , while the other layers of the underlayer membrane correspond to the previously discussed embodiment correspond.
- the diffusion openness of the roofing membrane is due to the inner layer made of polypropylene, the polypropylene fleece are designed so that they are in the train dig.
- Mortar or a is applied to the outer polypropylene fleece Sand / adhesive mixture or adhesive applied alone in such a way that a roof covering roof tiles over the Roof membrane to be attached to the precast concrete.
- the nonwovens must have a certain surface texture, which ensures that the fleeces are in the mortar, the sand / adhesive mixture or the adhesive and in the the precast concrete parts can claw.
- the fleeces are thermally solidified, i.e. the Nonwoven fibers are thermally attached to one another at certain points.
- nonwovens can be used that are mechanical are solidified, i.e. where the fleeces are mechanical are processed so that they have increased strength.
- the underlay membrane can be produced as follows:
- the two outer fleece made of polypropylene are covered with the diffusion-open polypropylene layer thermally, using ultrasound or connected with glue.
