• the enclosure made of non-combustible material can extend at least partially in a direction parallel to the installation.
• the installation channel runs through an installation recess that is formed in the installation base.
• the enclosure itself can be constructed in different ways. In one variant, it consists of at least one shaped part:
• the enclosure can consist of a block or a layered structure of one or more layers of gypsum plasterboard – that is, pressed or adhesive-bonded powdered gypsum between two layers of paper or cardboard – and/or gypsum fiberboard, whereby in the case of multiple layers, these are oriented parallel to the main plane (4") of the stud layer (4) or the installation base (7).
• the installation channel is then usually subsequently integrated into the layered structure or the block, for example by milling.
• the enclosure can also consist of a prefabricated component, especially a profile, in which the installation channel is included from the beginning, particularly in a U-shaped or box-shaped cross-section.
• a wall panel of this type comprises, firstly, a stud layer consisting of closely spaced wooden beam studs, which, in particular in the case of a wall panel mounted in a building, stand vertically, and at the end of the studs a strap running transversely to the direction of travel, the greatest extension direction of the studs, as well as at least one sheathing arranged on at least one side of the stud layer, which preferably extends over the entire surface of the stud layer.
• Sheathing in particular by means of one or more sheathing panels, is understood to be sheathing that additionally stabilizes and/or stiffens the wall panel.
• cladding can be carried out, in particular by means of at least one cladding panel, where the material properties of the cladding are concerned within the scope of the present application, in particular its, for example, fire-retardant material properties.
• sheathing and cladding can also be combined functionally, with the sheathing or cladding providing additional functions such as fire protection, sound insulation, etc., besides its stabilizing function. This is the case, for example, with gypsum fiberboards containing mineral fibers.
• a special package in the case that the corresponding wall is to have an installation channel, preferably running vertically, for an electrical cable, a special package, according to the invention an installation package, is present in the solid stud layer instead of one or a certain number of successive studs, a so-called stud package.
• the installation package is usually present in addition to the wooden studs and runs parallel to them at the desired position, and, like the wooden studs, is butt-jointed between the two transverse straps and screwed, nailed or clamped to them.
• a fire-protection-effective material is understood to mean, in particular, a fire-retardant or non-combustible material.
• the wooden studs are arranged so close together – or even touching each other – that the sum of the distances between the wooden studs, considered over the entire wall panel, is less than 5%, better less than 3%, better less than 2%, better less than 1% of the length of the wall panel in that direction.
• all wooden beam uprights should be the same thickness and/or width.
• Wooden beam stands with varying dimensions, especially different widths, can also be used, particularly within the framework of the stand packages described later.
• the straps are not as thick as the wooden beam uprights, but are significantly thinner in the direction of the thickness of the upright layer.
• the wooden beam uprights – especially those of special packages such as an installation package – have transverse strap recesses at their ends, the shape and dimensions of which are adapted to the cross-section of the respective strap – the two straps preferably having identical cross-sections.
• the strap recesses are open both towards the end face of the wooden beam upright and/or towards three adjacent longitudinal sides, thereby forming a narrower end tongue at each end of each upright.
• chords lie in the thickness direction of the post layer both on the same side in the thickness direction of the post layer and preferably with their outer side aligned with the outer side of the post layer, whereby alignment also includes deviations of up to 3 mm, better a maximum of 2 mm, better a maximum of 1 mm.
• the thickness of the cross ribs in the thickness direction of the stator layer is a maximum of 40%, better a maximum of 30%, preferably a maximum of 20% of the thickness of the stator layer.
• the cross-section of the belt is therefore larger in the longitudinal direction of the wooden beam uprights, which is also the longitudinal direction of the upright layer, than in the thickness direction of the wooden beam uprights, preferably by a factor of at least 6, better by a factor of at least 8, better by a factor of at least 9.
• This design offers a number of advantages: Firstly, from a production technology perspective - as explained in more detail later - this allows two belts to be arranged parallel and at a distance from each other for the production of a stand layer, so that the wooden beam stands can be placed one after the other between the belts and brought to a small distance from each other or into contact with each other, without the wooden beam stands being able to fall through between the belts, which also significantly facilitates the automated feeding, insertion and connection as well as further transport with the belts.
• the main advantage is that the high load-bearing capacity of the wooden posts in their longitudinal direction - the wooden beam posts are cut so that the primary grain direction coincides with their longitudinal direction - is maintained over most of the thickness of the post layer, regardless of whether and what compressive strength the strap has in this direction.
• the modulus of elasticity for bending is 11,000 N/ mm2 in the direction of the grain and 370 N/ mm2 perpendicular to the grain, and the compressive strength is 21 N/ mm2 in the direction of the grain and 2.5 N/ mm2 perpendicular to the grain.
• the compressive strength is limited to the smaller of the two compressive strengths. Compressive strength in the longitudinal direction of the wooden beam uprights and the compressive strength of the belt in its transverse direction.
• the belts will preferably consist of wood-based materials, preferably laminated wood, in particular plywood, preferably veneer plywood.
• the straps do not extend beyond the ends of the wooden beam uprights in the longitudinal direction, but are flush with them or, if necessary, are set back slightly from their ends, i.e. by one to a few millimeters.
• each of the wooden beam uprights is connected to each of the chords by a force-fit or form-fit connection, for example by clamping, nailing, or screwing.
• connecting elements as nails or screws – which may be made of metal or a wood-based material – are also inserted into the end tongues of the wooden beam uprights from the side facing away from the chord and extend into the chord, but preferably also from the chord side.
• At least the first and last wooden beam uprights are fixed to the straps, and if not all wooden beam uprights are fixed to the straps, then preferably at least 20%, better at least 30%, better at least 50% of all wooden beam uprights of a wall panel, preferably with the fixings evenly distributed between the unattached wooden beam uprights.
• initial fixing takes place when the straps and uprights are brought together, so that these connecting elements do not extend through the subsequently applied sheathing panel; however, additional fastening elements can be inserted from the outside of the sheathing panel into the uprights and/or into the cross straps and, if necessary, also through them to the end tongues of the uprights.
• the sheathing and/or cladding layers preferably consist of a fire-retardant and/or sound-absorbing material, in particular primarily of gypsum or another non-combustible mineral, for example gypsum cardboard boards or gypsum fiberboards reinforced with non-combustible fibers.
• chipboard and oriented strand boards can also be used.

• a so-called stud package a special package of the same width, namely a special door package or window package, is inserted during the production of the stud layer.
• This package is also prefabricated separately from the production of the stud layer and contains, in addition to the door or window opening and, if applicable, the surrounding jamb timbers, the remaining elements necessary below and/or above it, in particular partial studs that are shorter than a normal stud, in order to achieve the length configuration of the stud package thereby replaced.
• the fire-resistant, in particular non-combustible, material can be applied as a pasty, hardenable mass to the installation base, especially in several layers, or inserted into the installation recess.
• a shaped body with the dimensions of the installation channel can be inserted into the still pasty, curable mass at the position of the later installation channel, thus avoiding the need for subsequent milling out of the cured material.
• the form is well-defined and continuous in the direction of the installation channel and is made of a fire-resistant material, it can remain as the wall of the installation channel in the hardened mass; otherwise, it is removed from the mass after it has partially or completely hardened.
• a U-profile can be manufactured from fire-resistant material, in particular fire-retardant or non-combustible material, and used either alone or after fixing it to the connecting leg of the cross-section of the U-profile with an installation base as an installation package.
• Such a U-profile can be produced virtually endlessly, for example in an extrusion process, and the required lengths can be cut off without waste.
• the unused upper part of the U-profile forming the installation channel then represents an unnecessary weak point with regard to sound insulation and thermal insulation, which is why the U-profile should only extend over the length of the installation channel that is actually required.
