Description

Method and apparatus for producing roof membrane seams The invention enters a method and apparatus for producing roof membrane seams, wherein the edges of the roof cladding are placed one on top of the other.

The conventional, overlapped connection of Iiacizhautränder is usually made so that the two flat, overlapped edges be glued or welded in the area of their overlap (e.g. 3rd ER-PS 1.493 741).

In any case, the edges must be pressed vertically onto the Document required to establish the connection. With this well-known The type of connection required is a base that is as open as possible, however, e.g.

is not given by the mostly existing insulating materials. Unevenness in the surface and the resulting wrinkling inevitably lead to leaks.

On the other hand, insulation materials are usually of low temperature resistance, so that e.g. with hot air welding through the immediate Exposure to hot air can damage these insulation.

The invention is based on the object of a method and a device to create, with the unevenness of the base as a source of error for the tightness the connection as well as any damage to the base is largely eliminated and a quickly established and operationally reliable connection is achieved.

According to the invention, this is done in a method for production of roofing seams suggested that the edges should be erected from the plane of the roofing, in this position tightly to one another by pressure on their mutually facing sides connected, folded down towards the roof cladding and connected to it.

The method according to the invention has the advantages that with defined, constant pressure parallel to the roof surface can join the connection point, without the influence of irregularities in the substrate can. On the other hand, the upright position of the edges damages the insulating material by directly acting hot air or by activating agents or adhesives largely excluded.

While directed parallel to the roof surface by the action of the defined A tight connection between the two erected roof cladding edges takes place under pressure and is guaranteed, the connection of the folded so connected edges serves essentially for fixing or adhering to the roof membrane, with a tightness can also be advantageous for additional security, but not mandatory is required.

A particularly advantageous embodiment of the invention is distinguished characterized in that the edges are erected in different widths and through the protruding side strips of the wider edge are connected to the roof cladding. The means connecting the sides to one another can advantageously be used at the same time can also be used to connect to the roof cladding.

However, in special applications it can also be proceeded as follows: that the edges are erected in the same width. There is also still to point out that the advantages of the invention, for example, not visible Roof skin seams can also be achieved without turning it over to the roof skin, which tightly connected edges can therefore remain in an upright position.

The process according to the invention can also be carried out in an advantageous manner both when laying roof membrane on a suitable substructure as well as when laying appropriately designed, with overlapped edges the roof skin trained roof elements are used.

Depending on the prevailing circumstances, the connection between each other facing sides and / or with the roof skin by an adhesive, by hot air welding, , by activation or by applying an additional connecting strip take place. It is also possible to connect the edges together and to use different fasteners with the roof cladding Particularly Uniform and clean edge connections can be achieved in that the longitudinal edges of the margins are trimmed.

The inventive method can by several assistants and may be carried out with individual auxiliary devices. As special However, it is advantageous if a mechanical device is used, which according to the invention by the training as a mobile car with essentially two opposite horizontal pressure rollers and a downstream vertical one Pressure roller distinguishes itself, with the additional one for the respective type of connection required additional devices can be arranged.

To adapt to different material thicknesses and / or material accumulations, e.g. In the case of cross-joints, the pressure rollers and the pressure roller are expediently adjustable educated.

Furthermore, a trimming device can expediently be connected upstream be.

The invention is illustrated schematically below with reference to in the drawings illustrated embodiments explained in more detail.

In detail, Fig. 1-9 shows the respective cross-section through the roof skin edges during the individual process steps, FIG. 10, the complete device as mobile trolleys with the facilities for creating an adhesive bond, FIG. 11 shows the situation during the production of a glue connection, FIG. 12 shows the situation during the production of a connection by hot air welding, FIG. 13 shows the situation when establishing a connection through a connection strip activated on both sides.

The production process is easiest to understand when working together Consider Figures 1-11.

The carriage 1 containing the complete device with the four wheels 11 and the handle 12 is motorized with variable in a manner not shown Movable speed.

According to FIG. 1, the edges 21 and 22 of the roof skin 2 are placed one on top of the other.

During the movement of the carriage 1 is through the guide 13 first the edge 21 (Fig. 2) and then by the guide 14 of the edge 22 (Fig. 3) is raised. The unequally wide edges 21 and 22 gradually become perpendicular to the roof skin 2 Position (Fig. 4) and then transferred to the position inclined to the roof skin 2 (Fig. 5). As indicated in phantom in FIG. 5, the edges are if necessary 21 and 22 by two pairs of hemming knives 15 with straightened longitudinal edges 211 and 221 provided (Fig. 6).

According to FIG. 6, an adhesive 16 is dispensed from the container 161 via the application nozzle 1611 applied to the side of the wider edge 21 facing the edge 22, wherein the drying of the adhesive 16 is accelerated by a warm fan 17, if necessary can be.

By two parallel to the roof skin 2 effective, opposite one another Pressure rollers 18 are each with an adjustable pressure force via a compression spring 181 (Fig. 7) the edges 21 and 22 in an upright position on their mutually facing sides Connected tightly to one another via the adhesive 16.

Thereafter, the interconnected edges 21 and 22 become common gradually (Fig. 8) from the vertical to the horizontal position and there by the vertical pressure roller 19, which is also adjustable via a compression spring 191 is, with the provided with the adhesive 16, protruding side strips of the wider Edge 21 connected to the roof skin 2 (Figure 9).

Compared to the procedure described above, the result is Quotation according to Pig. 12 as an essential difference that here the car 1 a hot air nozzle 4 for welding the mutually facing sides of the edges 21 and 22 and a fieißluftdüse 5 for connecting the edges 21 and 22 with the roof skin 2 has.

In the embodiment according to FIG. 1v, is opposite to that described above Versions essentially different, that here an additional connecting strip 6 is introduced. This connecting strip 6 tird on both sides with a Activation means 61 acted upon, which consists of two containers 611 in a defined amount is applied via nozzles 6111. Only through the action of the activating agent G1 on the not yet fully reacted areas of the connecting strip 6 are these sticky, so that more advantageous processing than the zrrar is also possible Use of connecting strips on both sides is given from the outset. If necessary, between the nozzles 6111 and the pressure rollers 18 To accelerate the drying process, a warm fan can be provided as in FIG. 11.

For the sake of completeness, in connection with FIG. 13 it should also be mentioned that it is also possible without additional connecting strips if the roof cladding material is suitable, those required for the subsequent connection Activate surfaces immediately.
