Infilling system for walls and facings in construction

A face mounting infilling system for walls and linings of buildings. The infilling elements are designed at their ends in such a way that they may be clamped to the upper edges of lower linking units, which in turn are designed in such a way that upper linking units may be snap-locked thereon.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
This invention relates to an infilling system for walls and linings in 
construction. 
2. Description of the Related Art 
Systems conventionally used to infill walls and linings can be divided into 
three classes depending on the type of their placement: 
1. Systems with side overlapping, each unit on one side end overlapping the 
preceding unit and for its part on the other side end being overlapped by 
the subsequent unit. 
2. Systems with side assembly, the infilling units being inserted into one 
another laterally and in doing so often managing without special linking 
units. 
3. Systems with end attachment, the infilling units being placed next to 
one another and in doing so necessitating special linking units in order 
that their correct placement and water tightness are ensured. 
Compared to systems with side overlapping or with side assembly, systems 
with end attachment offer for example the following advantages: 
The infilling units can be individually mounted and dismounted without 
intervention in adjacent infilling units. 
Linking sections can assume support functions; this enables high support 
capacities so that expensive and unattractive substructures are 
unnecessary. Systems with end attachment used at present however have some 
disadvantages: 
One major disadvantage arises due to the danger that the infilling units 
escape from their receivers within the linking sections. In many systems 
this can be attributed to the fact that the corresponding infilling units 
have no side hold in the linking units and consequently can escape 
laterally when bending under load. In the case of other systems the 
infilling units do not have any effective end interlocking and therefore, 
especially with strong underpressure or with impact stress acting to the 
inside, they can separate. 
Another disadvantage of the system used at present with end attachment 
consists in that attachment of the corresponding linking units to the 
substructures cannot usually be done if all the infilling units have been 
definitively placed for the time being so that mounting entails a 
considerable expenditure of time and cost. 
SUMMARY OF THE INVENTION 
Therefore the object of the invention is to avoid the indicated 
disadvantages in a generic infilling system with end attachment. This 
object is achieved according to the invention by the measures indicated in 
patent claim 1. Advantageous embodiments of the invention are given in the 
dependent claims.

DESCRIPTION OF THE PREFERRED EMBODIMENT 
This infilling system is labelled in its entirely with reference number 1. 
The infilling system has infilling units 2 with cavities 3 formed on their 
ends such that their fixation is enabled on upper bulbous ends 4 by lower 
linking units 5. 
The shape of bulbous ends 4 corresponds to the shape of cavities 3 of 
infilling units 2 and therefore has an upper enlargement, consequently 
infilling units 2 can be fixed thereto. In this way infilling units 2 are 
secured both in the lateral direction as well as in the end direction, 
even if to a lesser degree. 
Lower linking units are made with two reversals 6 which are pointed to the 
inside and which are used to fix upper linking units 7 thereto and for 
this reason they are provided by two hooks 8 which bend elastically when 
upper linking units 7 are attached and then in turn assume their original 
position and in doing so cause coupling with reversals 6 of lower linking 
units 5. 
The mutual distance between reversals 6 in the embodiment will be 
sufficient to allow passage of possible screws or rivets 13 which enable 
attachment of linking unit 5. 
The upper external wings 9 of upper linking units 7 ensure end interlocking 
of infilling units 2. In order that upper linking units 7 and infilling 
units 2 are brought flush to the same height, the latter have a reduced 
thickness which corresponds to the thickness of wings 9. Wings 9 and 
infilling units 2 are joined to one another such that water percolation is 
prevented. Knurling 10 both on wings 9 and also on the section of 
infilling units 2 with reduced thickness improves water tightness. For the 
same reason the decrease of thickness of infilling units 2 from the 
outside to the inside increases so that an appropriate tilt 11 results. 
The width of the center section of upper linking units 7 is such that thus 
with it the distance between adjacent infilling units 2 is filled. This 
measure increases the stability of the entire system and is used to 
further prevent water percolation. 
Lower linking unit 5 consists preferably of a steel strip which is 
preferably shaped as shown. 
Reversal 6 preferably has a distance from the bottom of infilling unit 2 
such that a gutter which is used to drain water which may have percolated 
through can be formed. 
Because there are cavities 3 and bulbous ends 4, infilling units 2 can be 
mounted without upper linking unit 7 needing to be attached immediately., 
especially since an inherently stable unit is formed. Upper linking units 
7 can rather also be attached after all lower linking units 5 and all 
infilling units 2 have been mounted. 
Infilling units 2 and hooks 8 of upper linking units 7 should obviously 
consist of a material elastic enough to perform their task.
