Definitions
- the invention relates to a device for cutting insulation material, in particular mineral fiber insulation material sheets and / or mineral fiber insulation material panels.
- Mineral fiber insulation boards are cut to size, a cutting knife being generally used, which is applied to a large surface of the mineral fiber insulation web or mineral fiber insulation board and, for example, is drawn through the mineral fiber insulation web or mineral fiber insulation board along a predetermined and optionally marked line.
- the mineral fiber insulation sheet or the mineral fiber insulation sheet is placed on a base, usually the floor, and held by the person performing the cut with his hand or foot. In the case of relatively thin mineral fiber insulation webs and / or mineral fiber insulation panels, this has become
- the device consists of a support beam and a bracket arranged on one side, in which a clamping beam can be pivoted at different distances from the support beam.
- the support bar At the end opposite the bracket, the support bar has two guide strips with latching hooks, which serve to brace the tensioning bar when insulating material is inserted.
- the clamping bar can only be pivoted about a pivot point relative to the support bar. This device must be set for different material thicknesses of the insulating material in order to ensure a secure tensioning function.
- the invention is therefore based on the objective of creating a device for cutting insulation material which can be produced in a simple and cost-effective manner and, moreover, can be used in a simple manner.
- the solution to this problem provides a generic device, consisting of a support body and a movably arranged clamping element on the support body, between which the insulating material is arranged in a clamping manner, the support body and clamping element having a cuboidal configuration with a very small length, at least in terms of length Have thickness, the support body has at least one rectilinear cutting edge and the clamping element can be moved parallel to the support body along guide elements.
- an insulation material in particular a mineral fiber insulation sheet and / or mineral fiber insulation plate, can be arranged between the support body and the clamping element in such a way that the length of the insulation material to be cut projects beyond the cutting edge of the support body. Due to the mobility of the
- Clamping element there is the possibility to move the clamping element in the direction of the support body and to fix the insulation material in a force-fitting manner in the device.
- the insulation material is compressed.
- the insulation material is cut off along the cutting edge with the cutting knife known per se, the cut also being able to be carried out in one cut as a rule with insulation materials with a high bulk density or greater material thickness due to the previous compression. This results in straight cut edges, which simplify the installation of the cut insulation material and make it much safer with regard to proper installation.
- the guide elements are of rail-shaped design and are arranged in the region of the ends of the support body. Due to the rail-shaped design of the
- Guide elements allow precise guidance of the clamping element during the movement towards the support body or away from the support body.
- the guide elements are designed as round profile sections, two of which are arranged at a distance from one another at each end of the support body, which are fixedly connected to the support body, in particular are screwed and / or glued, and are penetrated by corresponding bores in the Extend clamping element.
- the main focus is on the advantage that such an embodiment can be produced very inexpensively and at the same time provides very good guiding properties for the movement of the clamping element relative to the support body.
- At least one energy accumulator in particular in the form of compression springs, is arranged between the clamping element and the support body and is tensioned when the clamping element moves toward the support body.
- the compression springs therefore ensure that in the initial state the clamping element is arranged at a distance from the support body in order to facilitate insertion of the insulating material between the support body and the clamping element. If the insulation material is arranged in the desired length between the clamping element and the support body, the clamping element can be pressed against the spring force in the direction of the support body.
- the handling person uses, for example, a foot with which he presses the clamping element in the direction of the support body. The cut can then be carried out at right angles to the longitudinal edges of the insulation material.
- the clamping element has a width that enables the clamping element to be operated by foot.
- the clamping element has a width that is less than the width of the support body and that the clamping element is arranged centrally above the support body. In this embodiment, it is easy for the handling person to visually recognize whether the insulation material to be suspended is arranged at the intended location in accordance with the cutting edge on the support body before the separating cut is carried out.
- the clamping element and / or the support body is preferably made of metal, in particular aluminum and / or wood. These materials ensure cost-effective production with a long service life. Such a device is also sufficiently robust so that the device can withstand the harsh conditions on construction sites.
- the cutting edge is designed in cross section as an L-shaped profile and fastened to the support body.
- the support body is thus protected over the cutting edge in such a way that an improperly executed cut cannot cut into the support body.
- the cutting edge has a cutting bar with a V-shaped groove for guiding a cutting tool, the cutting bar being screwed to the support body.
- the V-shaped groove is used to guide the cutting knife in order to provide the operator with assistance in making straight cuts.
- the support body has at least one opening which runs transversely to its longitudinal extension and is preferably arranged on the underside of the support body and into which one leg of a stop angle can be slidably inserted.
- a previously measured length of the installation space can be permanently set via this stop angle, so that subsequent cutting of the necessary number of sections of the insulation material is simplified and thus accelerated. With this stop angle, the handling person has the possibility of producing a large number of sections of exactly the same length in a simple and quick manner.
- the opening for the stop angle is preferably outside, in particular below, the cutting area of the Support body arranged so that the stop angle is not in the area of the cutting knife.
- the stop angle is in particular U-shaped and can alternatively have two legs guided into openings and a web connecting the two legs, the web being designed as a stop and arranged parallel to the cutting edge.
- the web of the stop angle can have a length scaling, which makes it easier for the handling person to set the length previously measured, for example, between the rafters in the device according to the invention.
- the clamping element is hinged on the support body, so that the clamping element can be transferred from a parallel arrangement to the support body into an approximately rectangular arrangement to the support body.
- a hinge between the clamping element and the support body considerably simplifies the handling of the device according to the invention, since the insulation material can then be inserted between the clamping element and the support body. An insertion between the two construction elements can therefore be dispensed with.
- This advantage is particularly evident in the case of insulating material with a high bulk density or high material thickness, since with these insulating materials it is only possible to push between two construction elements arranged opposite one another with great effort.
- the device shown in the figure for cutting insulation material consists of a support body 1 and a clamping element 2 movably arranged on the support body 1.
- Support body 1 and clamping element 2 are plate-shaped.
- the support body 1 each has two guide elements 3, which are designed as profile sections that are round in cross section and are arranged parallel to the narrow side of the support body 1 at a distance from one another.
- the guide elements 3 pass through corresponding bores in the clamping element 2, so that the clamping element 2 can be moved along the guide elements 3 relative to the support body 1.
- the guide elements 3 are firmly connected to the support body 1.
- the guide elements 3 can be screwed into the support body 1 and / or glued to the support body 1.
- each guide element 3 Between the support body 1 and the clamping element 2, a compression spring 4 is arranged in the region of each guide element 3, which holds the clamping element 2 at a distance from the support body 1, so that a space is arranged between the support body 1 and the clamping element 2 in which the insulation material, not shown, can be inserted.
- the guide elements 3 can also have locking devices, not shown, which secure the clamping element 2 on the support body 1.
- the support body 1 also has a cutting edge 5 which extends along a long side of the support body 1.
- the cutting edge 5 is part of a cutting bar, which has a V-shaped groove for guiding a Has cutting tool, the cutting bar is screwed to the support body 1.
- the device has a stop angle 6, which consists of a leg 7 and a stop element 8, which is perpendicular to
- Leg 7 is arranged.
- the leg 7 is slidably guided in an opening 9 in the support body 1 which extends transversely to its longitudinal extent below the support body 1.
- the leg 7 additionally has a length scaling 11 on its surface 10.
- the stop bracket 8 can be locked in a form-fitting or frictional manner in the support body 1 in order to fix a set distance between the cutting edge 5 and the stop bracket 8.
- a mineral fiber insulation sheet is inserted between the support body 1 and the guide element 3 until the front narrow side of the mineral fiber insulation sheet bears against the stop surface 8.
- the stop surface 8 has previously been set according to the length scaling 11 at a desired distance from the cutting edge 5.
- the clamping element 2 is displaced in the direction of the support body 1 against the spring force of the compression springs 4.
- the handling person can, for example, place a foot on the clamping element 2 and press the clamping element 2 in the direction of the support body 1.
- the mineral fiber insulation web is compressed very strongly and held in the device by friction.
- the mineral fiber insulation web is cut with a cutting knife parallel to the cutting edge 5.
- the cutting edge 5 or a supplementary one is used
- V-shaped groove of the cutting knife guide to make a straight cut.
- an insulating material with a very high bulk density it can it may be necessary to make two cuts with the cutting knife, each cut cutting through part of the material thickness.
- the mineral fiber insulating material web After removal of the section of the mineral fiber insulating material web separated in this way, the mineral fiber insulating material web is pushed back up to the abutment surface 8 before a further cut is carried out. In this way, the mineral fiber insulation web can be cut to length in the same sections, which are then available for the intended installation.
