Description

The invention relates to a wall element of a house, in particular a prefabricated house, which has an inner frame structure which is covered by a first cover plate and a second cover plate, wherein in the interstices of the frame structure and between the cover plates insulating material is arranged.

Wall elements of this type are known and are used in particular in prefabricated houses. In previously known solutions, the wall elements in question are usually designed as wooden walls in nailed construction, d. H. the individual components of the wall element are nailed together.

Block houses are also known as an alternative embodiment to said wall elements; accordingly, it is then mostly Vollholzwände.

A disadvantage of the above-mentioned generic wall elements that the insulation, ie the insulation, loose in the compartments is therefore us during transport or over time in normal use can sag down. Thereupon it forms in the Upper region of the wall element corresponding cavities in the interior, ie a thermal bridge or a gap without thermal insulation.

Sometimes problematic is the electrical installation in generic wall elements. For this purpose, conduits must be laid in the wall, which is a high cost. This is especially true for subsequent installations.

The present invention has for its object to avoid the disadvantages mentioned and to provide a wall element of the generic type, which ensures an improved, permanent thermal insulation. Furthermore, the laying of cables, in particular of electrical lines, should be particularly easy to perform, which should apply especially in subsequent installations. At the same time a high rigidity of the wall element should be given.

The solution of this problem by the invention is characterized in that both the first and the second cover plate is glued to the frame structure, wherein both cover plates are bonded at least over part of the contact surface between the cover plate and insulation material with the insulating material.

Preferably, both cover plates are glued over the entire contact surface between the cover plate and insulation with the insulating material.

The adhesive located between the cover plates and the insulating material is advantageously cured by applying an increased pressure; Furthermore, it is advantageously provided that the adhesive located between the cover plates and the insulating material is cured at an elevated temperature relative to the ambient temperature.

The interstices of the frame structure, which lie between the cover plates, are preferably completely filled with insulating material.

The frame structure is mostly made of wood. However, of course, another material can also be used for this purpose (eg plastic or sheet metal).

The frame structure may comprise at least one carrier in which runs at least one groove arranged in the longitudinal direction of the carrier and in its side region. This considerably simplifies the installation, in particular the electrical installation. The side region of the carrier, in which the groove extends, is preferably completely covered by the insulating material. Furthermore, it can be provided that the frame structure has a plurality of mutually parallel support, which are each provided with a groove. This increases the flexibility in the laying of cables to be installed, in particular of electrical lines.

At least one of the cover plates may be provided with a planking, in particular with a plasterboard, which then forms the surface of the wall element. It is provided in particular according to a development that both cover plates are each provided with a planking (in particular plasterboard) to form a wall element in the interior of the house.

However, it may alternatively be provided that one of the cover plates is connected to a further structure, in particular in the form of a thermal insulation composite system (ETICS), which is an outer wall of the house forms. In that regard, the invention then relates to the combination of the above-mentioned wall element with the further construction mentioned here.

In this context, it can be provided that the cover plate adjacent to the further construction is directly connected to the further construction. The connection between the further structure and the cover plate is preferably an adhesive connection. The further structure may consist of an outer plate, is arranged on the insulating material, wherein the remote from the outer plate surface of the insulating material is connected directly to the wall element.

Thus, the present idea on the production of both sides closed and glued wall elements by planking the stand (especially wooden stand) in particular with intermediate thermal insulation. Advantageously, an additional groove for the installation, in particular for the electrical installation, provided in the uprights.

The gluing is preferably carried out at elevated temperature and under pressure to ensure a firm bond of the individual parts of the wall element.

Regular inspections of the manufacturing process ensure the required level of process reliability.

The proposed wall elements allow in particular a simple prefabrication of the same, so that the actual production of a prefabricated house can be relieved.

The proposed gluing the items allows the minimization of the stator cross sections. Furthermore, hereby a good moisture protection of the thermal insulation is given.

The fixation of the insulation by laminating with the planking ensures in an advantageous manner that the thermal insulation can neither slip during transport nor later use of the wall element, so that undesirable voids are avoided in the interior of the wall element, which would have unfavorable insulation properties. The thermal insulation can not sag as a result of the proposed gluing, the thermal bridging freedom is thus ensured.

The proposed glued wall elements in panel construction (especially wood panel construction) are particularly advantageous for the production of walls for residential buildings. In general, however, such wall elements can be used in various areas of the construction industry (building construction, lightweight construction).

Advantageously, results from the inventive design of a wall element a small wall thickness at high static load; equally a high torsional rigidity is given.

The thermal insulation remains dry and effective in every case.

Due to the proposed grooves in the stands (especially wooden stands), there is the possibility of easier installation, especially electrical installation, which is particularly useful for subsequent installations.

• Die Wandstärke kann bei gleicher statischer Traglast reduziert werden.

Thus, the following advantages are summarized by the inventive design of a wall element:

• The wall thickness can be reduced with the same static load.

It is effectively prevented sagging of the thermal insulation inside the wall element.

Cracks can be minimized. At the same time creaking noises can be prevented.

This results in a flat surface as a carrier layer of the wall element.

Mounting options exist at every point of the wall.

Typically, wall elements according to the invention are performed with said thermal insulation. Special designs without thermal insulation are also possible.
