Definitions
- the present invention relates to a device for permanently connecting two plastic foam elements according to independent claim 1. Furthermore, the invention relates to a method for permanently connecting two plastic elements according to independent claim 10.
- plastic foam elements with particularly thick thicknesses were used in the insulation of buildings.
- plastic foam boards are known, which are formed from insulating materials such as rigid polyurethane foam, expanded polystyrene foam (EPS) or extruded polystyrene rigid foam (XPS).
- the isolation properties of XPS are very much dependent on the cell structure of the foam. Specifically, it is known that thick XPS plates have significantly lower thermal insulation properties than thinner XPS plates. This is due in particular to the fact that, as the plate thickness increases, deterioration of the cell structure and thus a reduction in the insulating properties of the XPS plate occur.
- the welding of the plastic foam panels by means of the above-mentioned heating blade has the disadvantage that the surfaces of the two plastic foam sheets to be welded together are changed or compressed by thermal and at the same time mechanical stress in their cell structure. However, this reduces the diffusion properties of the boundary layer, creating a barrier against water vapor diffusion. In addition, by the aforementioned method, excessive emission of styrene and pentane can occur, which are known to be very harmful to health.
- the present invention has for its object to provide an apparatus and a method for connecting two plastic foam elements, which overcomes the disadvantages mentioned.
- the invention provides a device or a method can be specified by which a compound of plastic foam elements can be achieved in a simple manner, which has a high vapor permeability and reduces the emission of toxins such as styrene to a minimum.
- the above object is achieved by a device according to the independent claim 1 and by a method according to independent claim 10.
- an apparatus for permanently connecting two plastic foam elements which has a first receiving device for receiving a first plastic foam element and a second receiving device for receiving a second plastic foam element.
- the device according to the invention has at least one heating element which is designed to heat at least the surfaces of the first and second plastic foam elements to be joined.
- the first receiving device can be arranged relative to the second receiving device in such a way that a gap region is formed between the surfaces of the plastic foam elements to be joined. This gap region has a width which is designed to receive the heating element without contact between the surfaces of the plastic foam elements to be joined.
- the inventive device for permanently connecting two plastic foam elements has a number of advantages. Thus, it is ensured by the non-contact arranged in the gap region heating element that the surfaces to be joined of the plastic foam elements are heated, without to touch the surfaces. This in turn effectively prevents a change in the cell structure occurs due to mechanical stress. Also, by heating the surfaces exclusively by heat radiation, it is ensured that a sufficiently thin weld seam is formed between the two plastic foam elements, which impairs the vapor permeability of the doubled plastic foam plate only to a small extent. Also, a very low maintenance is required by the device according to the invention, since the heating element is not in contact with the surfaces of the plastic foam elements and thus can not form residues on the surface of the heating element, which affect the functioning of the device.
- the first and / or the second receiving device having actuating elements which are adapted to press the two plastic elements after heating by the at least one heating element with their surfaces to be joined against each other. Accordingly, the first and second receiving devices can not only be used to form a gap region for heating the plastic foam elements; Rather, it is simultaneously possible to press the plastic foam elements with the aid of the receiving devices, after they have been heated by the heating element. Consequently, there is a reduced space requirement of the device according to the invention and an improved weld, since the plastic foam elements can be brought into contact with each other immediately after heating. It is particularly preferred if the two recording devices can be moved translationally in the vertical direction to each other.
- the movement of the first and second receiving device can be effected for example by a pneumatic, hydraulic, electrical or magnetic actuator.
- the first and second receiving devices are formed as flat plate elements and arranged plane-parallel to each other.
- the first and second receiving devices flat bearing surfaces for the first and second plastic foam elements. Accordingly, it is ensured that the plastic foam elements are not bent during the heating / Anpressvorganges, d. H. are not exposed to any additional bending moment.
- this has at least one heating station, which is arranged next to the receiving devices.
- the heating station is in particular designed to heat the at least one heating element.
- the heating element is designed as a passive heating element, d. H. it has no heating structures, such as heating wires.
