Definitions
- the invention relates to a building roof, preferably in a flat or flat-inclined configuration, consisting of a roof substructure, in particular of profiled sheets, and a thermal barrier layer consisting of at least one mineral fiber insulating element and at least one device for fastening the mineral fiber insulating element to the roof construction. wherein the mineral fiber insulating element has two substantially parallel and spaced large surfaces.
- the invention relates to a Dämm Mrsuggable for a particular flat or flat inclined building roof consisting of a roof substructure, in particular profiled sheets, and at least one Vor ⁇ direction for attaching at least one resistant mineral mineral fiber element to the roof substructure, wherein the mineral fiber insulating element two substantially parallel and has spaced apart angeordne ⁇ te large surfaces.
- the invention relates to a Mineralmaschine ⁇ insulating element for flat or flat inclined roofs of a meandering mineral fiber web having a plurality of mutually parallel webs, wherein the webs and their mineral fibers extend substantially perpendicular to the large surfaces and at least rich in Be ⁇ a large surface adjacent webs mitlenkungs Suitee mit ⁇ are connected.
- Lightweight thermally insulated Flachdachkonstruktio ⁇ NEN known from the prior art, which often form the upper end of a building, beispielswei ⁇ se a manufacturing and / or a warehouse, a meeting or the like and have a supporting roof shell, for example, from profiled steel sheets is composed of shells of local concrete, wood and wood-based materials, concrete or lightweight concrete elements.
- the roof shell in particular the profiled steel sheets, with consideration of the sag of the easily deformable roof shell, is provided with a sufficient gradient on a correspondingly designed substructure be ⁇ consolidates.
- the steel sheets have a profiling, which is placed in the direction of slope, ie in the direction of ridge eaves or transversely thereto.
- an airtightness layer is arranged above the load-bearing roof shell, which layer usually consists of relatively thin plastic or plastic-metal composite foils which loosely laid or, in the case of a flat roof construction presented here by way of example, be glued onto top chords of the profiled steel sheets. Quite essential here is a permanently airtight connection of the airtightness layer with adjacent components or in the region of natural ⁇ conditions.
- a thermal barrier coating is arranged, which spielmati consists of large-sized non-combustible rock wool insulation elements with a melting point of 1000 0 C according to DIN 4102 Part 17.
- These insulating elements must have the strength values required for the application type WD according to DIN 18165-1 or the application field DAD-dm according to DIN V 4108-10 and, for example, a compressive stress ⁇ 40 kPa, a tensile strength perpendicular to the plate plane ⁇ 7.5 kPa and a point load capacity at 5 mm compression> 500 N.
- the insulation elements When creating a building roof, the insulation elements must additionally be sufficiently strong enough to be able to absorb dynamic shear forces triggered by step movements.
- Rock wool insulation elements consist of mineral fibers bound with binders, the proportion of binder being limited by the requirements for non-combustibility of such insulation elements.
- a sufficiently large proportion of fiber is required, that is to say the bulk densities of insulation boards formed from the Dämmscherle ⁇ usually be more than about 120 kg / m 3 , in addition, the individual mineral fibers in as steep as possible Sieg ⁇ tion to the large surfaces of such insulation boards are brought.
- a mineral fiber web impregnated with binders and admixtures is subjected to intensive compaction.
- the binders used are mixtures of thermoset-curing phenol, formaldehyde and / or urea resins which, inter alia, contain small amounts of adhesion-promoting silanes.
- the amounts of binder are limited to less than 12% by mass in order to obtain the character of a non-combustible insulating material.
- insulating materials made of mineral fibers with a maximum binder content of 4.5% by mass are produced.
- water-repellent mineral oils, silicone oils and resins and / or organically modified silanes are provided. These additives also impart a slight adhesion of the mineral fibers to one another, thus reducing the release of fine constituents and mineral fiber fragments of the insulating material, but are not considered as binders in the strict sense.
- Mineral fiber insulating elements are produced from mineral fibers deposited on a conveying device and defiberized from a melt.
- the mineral fibers deposited on the conveyor are aligned substantially parallel to the large surfaces of the mineral fiber web designated as the primary web.
- the primary nonwoven is then unfolded and subjected as a secondary web to intensive upsetting in the conveying direction and / or at right angles to the large surfaces of the secondary web.
- the resulting structure of the secondary web is then fixed by curing or solidification of the binder in a curing oven. Due to the compression in only two directions, the mineral fibers remain transverse to the conveying direction predominantly in horizontal storage.
- This orientation of the mineral fibers results in that the bending tensile strength in this direction is substantially three times as high as in the conveying and / or unfolding direction.
- the relative deformability that is also the lower shear strength in this direction is accompanied by a higher cleavability of the secondary nonwoven.
- individual sections are separated as insulation panels. These insulating panels are normally used in a width adapted to the means of transport of conventional way 1, 2 m separated, the length of the insulating panels with the width of the secondary fiber web, for example, 2 m matches.
- the insulating panels are generally laid transversely to the profile direction of the steel sheets.
- the thermal insulation panels In order to exploit the high bending tensile strength of the thermal insulation panels in the production transverse direction, they are separated from the endless insulating material web according to their width and then laid transversely to the profile direction of the support sheet metal sheets.
- the compressions of the fiber web are effected by pressure and shear forces acting on the two large surfaces.
- the final structure is fixed by solidifying the binder, for which purpose the fiber web is guided in a curing oven between two conveying devices arranged one above the other.
- the fibers in both the large surfaces and the layers immediately below are aligned parallel or flat to the large surfaces.
- the resulting thermal insulation panels thus have about 10 to about 25 mm thick, to about 180 to about 210 kg / m 3 compressed surfaces, while the main part of the insulation board gross densities of at least 120, preferably> 130 kg / m 3 .
- the position of the fibers in the surfaces and near-surface layers, their compaction and the configuration of the fiber masses underneath lead to high compressive strengths and to a high point load capacity with regard to the attachment of flexible roof seals by means of screws and pressure plates, which is also the case in FIGS Writings of the manufacturer is particularly highlighted.
- Long drawn cutters for example U-shaped rails made of thin sheets, can not be pushed into these surfaces, or can only be pressed in only slightly. Although thin sheets in particular have a greater cutting effect in the fiber mass, kinking of the legs of the rails tends to occur rather than splitting the fiber mass in the required manner.
- the actual sealing of the flat roof construction is arranged, which often consists of webs of plastics or elastomers or glued-on bituminous sheets. These webs are usually 1 m or 1, 2 m wide and are connected in the edge region with the help of screws through the thermal insulation and the air-tightness layer through with the load-bearing Dachscha- Ie.
- the roof shell consists of the above-described profiled steel sheets
- the connection of the webs is basically effected in the region of the upper belts of the steel sheets, that is to say in the areas of the steel sheets resting against the thermal insulation layer or the air-tightness layer.
- self-tapping screws are used, the tips of which are designed as drills and whose average pull-out values are generally dependent on the sheet thickness and the shape of the thread or a molded sheet bead and average 0.2 kN.
- the self-drilling screws have a second thread below a head.
- the material-appropriate contact pressure on the airtightness layer and the thermal insulation layer is usually carried out by elongate, in itself stiffened metal plate with ist ⁇ rounded narrow sides having dimensions of, for example, 40 mm x 82 mm.
- the metal plate has a central bore, wherein the metal plate is formed in the region of the bore in such a way that the head of the self-tapping screw is recessed in the plate.
- the drill screw on a first upper thread, which prevents passage of the head through the roof seal, namely arranged on the thermal barrier coating webs.
- the screws are arranged at the edge of the tracks in rows so that a next track of the roof seal is passed over the screws and connected in the edge region with the already mechanically fastened path by gluing or welding. By overlapping adjacent webs of the roofing the screws are covered.
- the resistance of the attachment of the thermal barrier coating is largely determined by the strength of the insulating elements.
- This strength of the insulating elements is not constant, but falls under the effects of pressure, train, humidity, temperature and time, so that sets over the lower level compared to the initial level of strength over time. At high initial strength values, it is therefore attempted to at least partially reduce this strength reduction. wise to compensate.
- high preloads are selected by tightening the drill screws with a high torque, so that the pressure-compensating metal plates are drawn into the insulating elements even with insulating elements with high strength. As a result, unwanted accumulations of water and dirt deposits at these points on the roof seal are thereby formed.
- insulating boards of mineral fibers which have a surface layer which is about 15 to about 25 mm thick and which is compressed to a value of generally 180 to 220 kg / m 3 , and therefore permits comparatively high point loads.
- the large number of metal components built into such a flat roof construction, in particular the many self-tapping screws also leads to greater heat losses, even at higher insulation thicknesses adapted to the increased requirements for thermal insulation, since the self-tapping screws form thermal bridges even in the arrangement described above.
- inclined roof structures which are often covered with sheets of, for example, aluminum, copper, titanium zinc, galvanized galvanized steel, austenitic steels, lead or the like.
- the individual cover elements are called coulters and formed from strips and sheet metal.
- folding and strip roofs are differentiated.
- folded seams the connection of the individual shares with each other usually takes place in the form of single or double standing seams or angle seams.
- the attachment of the shares is done by adhesive. Fixing and sliding or sliding joints are designed, the latter intended to allow thermally induced longitudinal movements of the coulters.
- the adhesives consist of narrow metal strips and are made of suitable materials with prescribed minimum thicknesses> 0.4 mm for stainless steel,> 0.6 mm for galvanized steel sheet and ⁇ 0.7 mm for titanium zinc or> 0.8 mm for aluminum ,
- the sliding covers have either elongated holes or a correspondingly movable upper part, in order to allow movement of the shares relative to the adhesive.
- This known holder consists of a head part for supporting the shares and a foot part for coupling the holder with a support structure. Between the head part and the foot part, a connection back is provided.
- the foot part is arranged in a support element, which is movably coupled to the foot part.
- the foot part can be plate-shaped or round in cross-section, wherein the support element has a shape corresponding thereto.
- the adhesions and holders are integrated in a seam connection between adjacent shears and are welded together in the case of a welded connection with the shears.
- the holders are connected, for example by means of countersunk screws with the ground.
- Width and length of the pawls, material thicknesses, number and distance of the adhesions are specified for example in DIN 18339.
- Standard Scharrenbreiten of Scharren are 520, 620, 720 and 920 mm.
- the adhesions consist partly of extruded solid metal bodies with rounded heads. The number and spacing of the adhesions depend on the width of the scraper, length, height of the building, the position within the roof area and amount to ⁇ 500 mm to 210 mm to approx. 4 to 8 pieces per m 2 .
- the adhesives usually have a constant length, so that deflections of the supporting roof shell are transferred to the roofing.
- a vapor-damping airtightness layer is likewise provided, on which the thermal barrier coating is arranged, which consists, for example, of rollable lightweight mineral wool insulating felts.
- the individual layers of the mineral wool Dämmfilze are, as far as the foot points of the adhesive and this allow themselves, largely dense.
