Description

The invention relates to a three-dimensional template, a method and a cutting device for producing a rafter cutout in an insulating panel.

From the prior art, in particular the DE 20 2007 005 800 U1 and the DE 297 17 912 U1 , Cutting machines, in particular for cutting plates of a thermally separable material known. Such cutting machines are used for cutting insulating panels or full heat protection panels, for example hard foam panels, in particular made of polystyrene.

Since the main field of application of these cutting machines is generally on construction sites, these equipment must meet the usual requirements in the construction industry, i. The cutting systems must be robust on the one hand and on the other hand of a compact and manageable structure so that they can easily be transported to the construction site and on site and, if necessary, can be used on conventional scaffolding without limiting the freedom of movement of a builder. In addition, such cutting systems must be easy and quick to use.

A disadvantage of the above-mentioned cutting machines is that they in particular have a very complex structure and can cause difficulties in the quick and easy handling by a builder by the variety of possible settings.

From the DE 20 2006 001 903 U1 is a template for the production of a rafter cut in an insulation board known, which advantageously has a comparison with the aforementioned cutting equipment particularly simple structure. However, a particular disadvantage of this template is that of the template and the cutting device During the cutting, the operator must take extreme care to ensure that, during the manual cutting movement of the cutting element, for example a heating wire, it always guides it perpendicular to the template. That's practically impossible. However, deviations have the consequence that unwanted gaps remain between the over a building wall protruding rafter head and provided with rafter cut insulation board. In addition, a corner cutter is required, in which the course of the cutting member must be specified in the cutting device by adjusting an angle, the cutter operating the cutter must be extremely careful when cutting that the cutting device in the manual guided cutting movement always parallel to the lower edge of the template to be led. This is practically impossible with manual operation.

Based on this prior art, the present invention seeks to develop a three-dimensional template for producing a rafter cut in an insulation board, which is simple, is suitable for working on a scaffold, allows efficient and precise work, easy to use , which allows cutting of well-known EPS, XPS and mineral wool slabs, ensures a high quality of the work done, does not require subsequent closing of joints, is robust and durable, requires little maintenance and / or is light. These tasks are also to be achieved by a further developed method and a further developed cutting device for producing a rafter cutout in an insulating panel.

This object is achieved by a three-dimensional template having the features of claim 1.

The inventive three-dimensional template is designed in the manner of a cutting drawer for producing a rafter cutout or the like in an insulating panel for a building wall. The template comprises a substantially U-shaped body, which is placed on an insulating plate, such that the U-base is placed on the mounted in the state of the insulating board upwardly facing side or top surface, a U-legs on the in the assembled state of the insulation board to the building wall facing side of the insulation board abuts and the other U-leg rests on the opposite side in the assembled state of the insulating panel of the building wall of the insulation board. The U-base and each U-leg form an area or span an area. According to the invention, the base body formed in a U-shaped manner is formed from a frame whose free space forms the rafter cutout, wherein the edges or edges or sides of the frame delimiting the free space or specifying the free space define the guide for a cutting device or form a cutting organ.

The term "as assembled" is used to clearly indicate the individual sides of the insulation board. In fact, the insulation panel is not in the assembled state when making the rafter cutout, but is mounted on the building wall only after the rafter cutouts have been made or.

The three-dimensional template according to the invention for producing a rafter cutout in an insulating panel is surprisingly simple. It is very easy to put it at a predetermined location on an insulation board or set and usable due to their simple and compact design for working on a scaffold. The cutting member of the cutting device is guided in this case to the free-space facing edges of the frame, wherein the cutting member is always supported when cutting on two support or at two contact points or surfaces. The one edition or investment point is in this case on one side of the insulation board, the other support or investment point can be found on the other side of the insulation board. This makes rational, time-saving and precise work possible. The three-dimensional template is particularly easy to use due to its simple structure. For example, with the three-dimensional template, rafter cut-outs can be cut into EPS (expanded polystyrene), XPS (extruded polystyrene rigid foam) and mineral wool slabs. Due to the improved guidance of the manually guided cutting member, which always has contact with two contact or contact points or surfaces during cutting, a high quality of the work performed is achieved. Thus, advantageously no more joints between rafter head and insulation board, so that a subsequent closing of joints no longer required. The template according to the invention is due to their simple and effective construction robust and durable. Maintenance is hardly necessary. In addition, the three-dimensional template can be particularly easily formed.

A development of the invention provides that each U-leg of the U-shaped main body is pivotally mounted on the U-base of the U-shaped main body. Particularly suitable for this purpose is a simple hinge, which is also referred to as a rolled hinge. This consists of two parts, the trades, which are permanently connected to a pen.

Due to the pivoting of the U-legs is achieved that the three-dimensional template can also be placed on an insulating plate whose, in the assembled state of the insulation board facing upward side has a matching to the roof pitch miter cut. After placing the three-dimensional template, the opposite U-legs have a height difference, this difference in height, when it is connected by a straight line, corresponds to the inclination of the miter cut or the roof pitch. Thus, this tendency can be easily transferred to the formation of the bottom or the background or reason of the rafter cutout with the template according to the invention.

In order to transfer the inclination exactly, it is provided according to an advantageous embodiment of the invention, that the effective length of the U-legs of the body, so the length of the free space bounding edges of the longitudinal frame members, is the same size.

An effective length is always understood as the path along which the cutting element is actually guided. Thus, the length of a frame part of the U-leg can be quite longer than the effective length of the frame part.

A development of the invention provides that the effective length of each U-leg of the body, so the length of the free space bounding edges of the longitudinal frame members, is variable.

As a result, the three-dimensional template can advantageously be adapted to the length of the rafter head and this can be transferred exactly for the production of the rafter cutout. Precise work is possible.

It may be particularly advantageous if the effective length of the longitudinally parallel frame parts of the U-base, ie the length of the free space bounding edges of the longitudinal frame members, is variable.

This allows the template to be adapted to any thickness of the insulation board. Thus, a template for a variety of different insulation boards can be used.

A further development of the invention provides that the distance between the edges of the frame parts of the base body which run in the longitudinal direction and delimit the free space can be changed.

As a result, the template can be adapted to the width of the rafter for producing a precise and precise rafter cutout.

The simplest and most advantageous such an adaptation can take place in that the effective length of each transverse and arranged in the region of the U-base remote end of the U-leg frame part of the body, so the length of the free space bounding edges of the transverse extending frame parts, is changeable.

As a result, the distance between the longitudinally extending frame parts of the base body can be changed, whereby the template the width of the rafter adaptable st.

A development of the invention provides that the frame or the frame parts surprisingly simple consists of interconnected rails or exist, which are mutually displaceable, fixable and again detachable.

This allows the space surrounding the frame to be adapted to the desired rafter cut-out.

It may be advantageous if the frame consists of interconnected rails which are mutually displaceable, fixable and detachable, wherein the rails are formed as each provided with at least one slot flat elements, wherein two flat elements via at least one leading through the slots fixing means, preferably by a wing clamp or more preferably a quick release, mutually adjustable or positionable and are releasably connectable to each other.

The flat elements provide a very good opportunity individual rails or frame parts, in particular via simple pivotal position to connect with each other. The flatness of the elements also favors the easy and safe support of the template on the insulation or thermal insulation board.

An advantageous embodiment of the invention provides that the U-legs on the side facing the insulation board side each having at least one upon application of the U-leg to the insulation board, in this superficially penetrating pin for fixing the U-leg to the insulation board. So the template is held securely on the insulation board for cutting. Of course, the pin does not penetrate so deep into the insulation board, that this is disturbed in their function.

A further development of the invention provides that the cutting device has a tensioned heating or glowing wire, wherein the substantially forming a straight heating or glowing wire on the free space bounding edges of the body is feasible, wherein the heating wire when guiding a connection produced between the frame parts of the opposite U-legs. The heating or glow wire is supported during cutting continuously on two support or on two contact points or surfaces, so that an accurate and precise cut is obtained.

It can be advantageous if each transverse part of the frame arranged in the region of the end of the U-leg remote from the U-base Base body a scale on the opposite side of the thermal insulation board. It is thereby achieved that the measured width of a rafter head can be relatively quickly transferred to the template by varying the effective length of said transverse frame members. The effective length is readable at the scale arranged according to the invention.

A development of the invention provides that at least one, preferably both longitudinally extending frame parts of each U-leg of the body have a scale on the, the thermal insulation panel opposite side. It is thereby achieved that the measured height of a rafter head can be relatively quickly transferred to the template by varying the effective length of said longitudinal frame members. The effective length is readable at the scale arranged according to the invention.

Preferably, the template consists essentially of metal. The insulation board may advantageously be an EPS or XPS insulation board.

It may be advantageous if the upper edge of the transverse frame part, in particular the upper edge of that of the two transverse frame parts, which is arranged in the mounted on the Dämmstoffplafte state of the stencil further down, bevelled, whereby a beveled surface is formed, which from the insulating panel facing side of the upper edge down to the outside of the frame part. Even with large, on the insulation board to be transferred inclination of the rafter a dimensionally accurate rafter cut is achieved. Alternatively, it may also be expedient if the or the above-mentioned transverse frame member is formed so thin that the upper edge of the frame member is substantially negligible even with a large inclination of the rafter in the dimensionally accurate transmission of the inclination of the rafter on the insulation board ,

Become in the Fig. 1 to 8 the same reference numerals used, they designate the same parts or areas, so that in order to avoid repetition need not be discussed again in every description of the figure on an already described component.

In Fig. 1 is a schematic perspective view of an inventive three-dimensional template 10 in the manner of a cutting loader for producing a rafter cut or the like in an insulation board 12, which is to be mounted on a building wall, shown. The three-dimensional template 10 comprises a substantially U-shaped basic body, which is placed on an insulating material plate 12, not shown here, for example, an EPS or XPS plate.

The U-shape is in this case formed by three surfaces, wherein a central surface of the U-base and two laterally adjoining surfaces form the U-legs. According to the invention, however, the surfaces for forming the main body of the template 10 are not formed continuously with material, but instead have recesses, such that the basic body only has one frame of frame parts 38, 42, 50 or a frame construction.

In Fig. 2 is schematically the template according to the invention Fig. 1 shown with unfolded U-legs in plan view. Here are the free space 26 form recesses good to recognize.

However, the free space basically only arises when the template 10 - as in Fig. 3 clarified - arranged U-shaped or placed on an insulating plate 12. Here, the free space 26 to cut out the part 68 for producing the rafter cut.

The three-dimensional template 10 can be placed on the insulating panel 12 such that the U-base 14 rests on the upwardly facing side 16 of the insulating panel 12, wherein the upwardly facing side 16 of the dam material plate 12 according to Fig. 3 may have a miter cut, which has a slope which corresponds to the inclination of the rafter, not shown here. The U-legs are preferably connected via simple hinges 76 pivotally connected to the U-base, so that the U-shaped body when placing on a miter cut provided upwardly facing side 16 of the insulation board 12 moves like a rhombus similar to a parallelogram.

The one U-leg 18 rests on the in the assembled state of the insulation board 12 facing the building wall side 20 of the insulation board 12, while the other U-leg 22 rests on the opposite side in the assembled state of the insulation board 12 of the building wall side 24 of the insulation board 12. This is evident in Fig. 4 illustrated schematically the inventive template according to Fig. 1 represented together with cutting device 32 in side view. For illustration is also Fig. 5 approachable, which schematically according to the invention template Fig. 1 without cutting device 32 in side view, wherein in Fig. 5 also the tapered upper edge 52 of the frame member 50 is shown, whereby a tapered surface 82 is formed, which of the insulation board 12 facing side of the upper edge 52 extends down to the outside of the transverse frame part 50.

As already stated, the essentially U-shaped base body is formed from a frame or frame parts 38, 42, 50, the free space 26 of which forms the rafter cutout, wherein the edges 28 or edges bordering the free space 26 or the free space 26 can be predetermined Side of the frame 38, 42, 50 the guide for the example in Fig. 4 shown cutting member 30 of a cutting device 32 form.

Each U-leg 18, 22 of the U-shaped main body is pivotally mounted, preferably by means of a simple hinge 76, on the U-base 14 of the U-shaped base body.

The effective length 34 of the U-legs 18, 22 of the body, so the length of the free space 26 bounding edges 28 of the longitudinal frame members 38 is the same size, as in Fig. 2 clearly illustrated.

The effective length 34 of the U-legs 18, 22 of the body, so the length of the free space 26 bounding edges 28 of the longitudinal frame members 38, is variable.

The effective length 40 of the longitudinally parallel frame members 42 of the U-base 14, so the length of the free space 26 bounding edges 44 of the longitudinal frame members 42, is variable.

The distance 46 between the longitudinally extending, the free space 26 bounding edges 28, 44 of the frame parts 38, 42 of the body is also changeable. This is preferably carried out by the fact that the effective length 48 of each transverse and arranged in the region of the U-base 14 remote end of the U-leg 18, 22 frame member 50 of the body, so the length of the free space 26 bounding edges 52 of transversely extending frame parts 50 is variable.

In order to realize the mentioned possibilities of change, it may be advantageous if the frame 38, 42, 50 - as shown here - consists of interconnected rails, which are mutually displaceable, fixable and detachable again, wherein the rails than each with at least one slot 54 provided flat elements are formed, wherein two flat elements via at least one through the slots 54 leading fastener, preferably by a wing clamp screw 56 are mutually adjustable and releasably connected to each other.

In a preferred, in particular very robust and simple embodiment, the U-base comprises two parallel and spaced flat elements 42, which are each provided with a slot 54. On the one side of the two flat elements 42, each flat element 42 is connected to a fixedly arranged hinge 76. These hinges 76 are in turn connected to a respective longitudinal, provided with a slot flat member 38 of a U-leg 18, wherein the hinges 76 are also arranged fixedly to these flat elements 38 here.

Although on the other side of the two flat elements 42, each flat element 42 is also pivotally connected to the flat elements 38 of the other leg 22. Here, however, the hinges 78 are only locally fixed to the flat elements 38 of the other U-leg 22 and are otherwise feasible in the slot 54 of the flat elements 42, fixable and detachable. In the case of a simple hinge, this means that one trade of the hinges 78 is fixedly connected to the flat elements 38 of the other U-leg 22, and the other trade of the hinges 78 is connected to the flat elements 42 by means of a wing clamping screw 56 guided in the slot 54, whereby this industry and thus the other U-leg 22 is slidable along the slot 54 of the flat elements 42, but also at any desired location. As a result, the template 10 can be adapted to any thickness 64 of the insulating panel 12.

To avoid a short circuit, the U-Schenkei 18, 22 are isolated from each other. Preferably, this isolation is provided on the fixed hinges 76. Alternatively, the flat elements 42 of the U-base 14 may also be made of an electrically non-conductive material.

Each transverse and in the region of the U-base 14 remote end of the U-leg 18, 22 arranged frame part or flat element 50 of the body has two slots 54 and two separate mounting holes 80. The two mounting holes 80 are each with one Wing clamping screw 56 connected to the slot 54 of one of the two flat elements 38. The two elongated holes 54 of the flat element 50 are connected to the slot 54 of the other of the two flat elements 38, each with a wing clamping screw 56. As a result, an easy-to-use adjustment of the flat elements 38, 50 is achieved in a simple manner against each other in the vertical and horizontal directions.

For dimensionally accurate adjustment of the template 10, the flat element 50 has a scaling 60 on the, the insulating board 12 opposite side.

At least one, preferably both longitudinally extending frame parts 38 of each U-leg 18, 22 of the base body also have a scale 62 on the, the insulating board 12 opposite side to dimensionally accurate adjustment of the template 10.

The in the Fig. 4 and cutting device 32 shown in FIGS. 6-8 is a heating or glow-wire cutting device 32, wherein the heating wire 30, which forms essentially a straight line, can be guided on the edge 28, 44, 52 of the base body delimiting the free space 26, the heating wire 30 at Lead a connection between the frame parts 38, 50 of the opposite U-legs 18, 22 produces.

The cutting device 32 comprises a bow-shaped, substantially H-shaped frame having in the lower region between the free ends of the H-legs 70, a substantially parallel to the H-base 72 clamped heating wire 30, which through the H-base 72nd produced connection between the H-legs 70 is such that the H-leg 70 parallel to each other from a vertical position a) in a predetermined skew b) can be brought. As a result, the handling when cutting is much easier.

To hold the predetermined inclination, it may be advantageous if a fixation, preferably by means of a clamping screw, is provided at the ends of the H-base 72.

Preferably, for this purpose, the H-base 72 is formed as a fulcrum rail.

Parallel to the H-base 72, a tensioning device 74 between the H-legs 70 is still provided at the, the clamped heating wire 30 opposite side, which serves for easy and quick clamping of the heating wire 30.
