Description
~ 325 045~4-7/iY
The present invention relates generally to an improved building wall construction and, in particular, to a building wall constructed of porous or aerated concrete blocks which is specially coated and results in an accurately dimensioned and decorative wall.
Exterior or interior building walls constructed from bricks in the conventional manner are not true to size on account of the bricks used. The result is inaccurate and skewed wall surfaces that may be damaged by a great number of environmental influences. A special plaster is required both on the inside and outside of the brick wall in order to compensate for this lack of dimensionai accuracy. Normally, one or two layers of plaster having a total thickness of from about two to three centimeters is used. This procedure results in high material and labor costs and, in the case of large buildings, it also leads to a significant loss of space. In addition, such building walls must be allowed to dry for a long period after erection and plastering. Generally, a drying time of five to six weeks is necessary.
It is an object of the present invention to provide a bricked, plastered exterior or interior building wall which is plastered with optimal dimensional accuracy and in a particularly advantageous way. It is a further object of the present invention to provide a protective and decorative coating which is applied to such walls.
'~
~2 5 ~32 5 04544-7/~Y
The above objects are accomplished in accordance with the present invention by the exterior or interior wall first being constructed from aerated or porous concrete blocks or bricks. On the surEace of this wall, at least the joints are covered either by means of plaster and/or a material with aerated concrete granùlate or with the excess adhesive squeezed from the joints between the blocks. A not readily inflammable, expandable and moisture-regulating layer having a structured surface formed from a mixture of fibers is also applied to this wall. The fiber mixture may consist only of natural fibers or only of synthetic fibers or any desired composition of natural and synthetic fibers.
The joints between the concrete blocks are covered in order to eliminate visible joints which would result in an undesirable pattern on the wall. The joints may be covered by means of plaster or a material containing aerated concrete granulate. Frequently, the blocks are placed one on top of the other with the use of an excessive amount of adhesive in the joints. The excessive adhesive is squeezed from the joints when the blocks are pressed together. This excess adhesive is scraped off with a trowel or spatula in such a way that the joints are evenly closed or sealed.
~25~32~ 04544-7/iy It falls within the scope of the invention to coat, iE desired, the total wall constructed from the porous concrete blocks with a thin-bed plaster that may have a thickness of about two to three millimeters. This extremely thin wall coating serves to cover the wall and/or the plaster covered ~oints. This first coating applied to the building wall may be a thin-bed mortar or plaster and/or a slurry and/or a thin coating or a silica sand-containing dispersion paint.
Subsequently, a structured surfacing consisting of a mixture of fibers is applied to this wall coating. The structured surface consists of a mixture of natural fibers which has special material properties such as extensibility, moisture regulation, capability of breathing and heat and sound insulation properties.
In particular, the mixture of natural fibers may consist of natural products such as cotton, grasses and plants, which are mixed together. For this purpose, natural fibers are used which are highly stable and compatible with each other and with a weight such that a uniform surface pattern is obtained when the coating has been completed.
The natural fibers are interlocked with each other, thereby leading to a large number of connections or linkages.
The fibers are not disposed one on top of the other or next to ~,:
j,'?~ ~
~ 2~325 04544-7/iY
each other independently, but rather are intertwined with each other and anchored by combining them with a liquid such as water. This results in high extensibility, so that the coating is capable of contraction and expansion in the presence of great temperature variations without alterations or changes resulting in the coated surface. Also, the coating will not detach itself from the wall. Following its application and drying, the coating becomes a component of the base or substratum because the fibers will partially be anchored also in the base.
Advantageously, a fiber mixture of Hirsutum-type cotton fibers of the following composition is used:
12% - 23% spun cotton;
30% - 40~ first cut linters; and 43% - 53% second cut linters.
A particularly advantageous extensible and moisture regulating coating with high flammability retarding property is obtained if the fiber mixture consists of Hirsutum-type cotton fibers with the following composition:
17% spun cotton;
35% first cut linters; and 48% second cut linters.
The fibers of spun cotton may have a length of 20 to 50 mm and they may have as cross~sectional features a ~L~5~3325 0454~-7/iY
longitudinal axis of 19 um and a transverse axis of 8 um. The first cut linters may have a length in the range of 2.5 to 6 mm, a fiber diameter in the range of 17 to 27 um and a cellulose content of 83 to 86%. It has been found preferable that the first cut linters used have a length of about 3 mm. The second cut linters may have a length in the range of 2 to 3.5 mm, a fiber diameter of 17 to 27 um and a cellulose content of 83 to 86%.
The cotton fibres used have a perfect crystalline structure (example: linters 2.15 ce]lulose, 1.48 crystallinity). Preferred are fibers with a high orientation of the micellar strands and fibrils.
The fibers are processed by first carrying out alkaline pressure boiling followed by multi-step bleaching.
Especially sodium chloride and soda lye are used for the bleaching. Following drying, the material is calendered. The cotton is then reflocculated.
In addition to the main component cotton, the mixture may contain an addition of cork, coconut fibers, ground rice shells, whole rice shells and Andnes grass as well as vermiculites. The cotton fibers of different length used for the cotton coating are dispersible with water.
.~
~L~5gl332~i 04544-7/iY
Another coating may be formed having different proportions of cotton. Cotton fibers of different lengths are admixed and, for example Asian grasses and plant and tree components, for example components of a Japanese cypress, are added. All of the additives may be added to the coating according to the invention individually or with any desired composition.
Such coatings result in good sound insulation properties since the sound absorption of the coating is very good. Furthermore, good thermal insulation is achieved. The coating according to the invention regulates the moisture because of its capability of absorbing moisture without change in structure. Regulation of moisture, as used herein, means no flowing water.
Another advantage of the present invention is that soiled or damaged parts of the wall may be restored easily by providing the wall with a new coating or restoring the coating.
All decorative requirements with respect to natural and synthetic fibers may be satisfied.
According to another aspect of the present invention, an extensible and moisture-regulating coating with high flammability retarding property having a structured surface and containing a mixture of intertwined and anchored fibers as ~2~325 04544-7/iy described above is provided for application to exterior or interior building walls to which said coating may be applied in particular as plaster. This coating may be a coating that is used for new plaster work, i.e., for renovation work, or a coating for a new building with exterior or interior walls made of any type of construction material. According to the present invention, the fibers used for this coating include a cotton mixture and may contain additions of cork, coconut fibers, ground rice shells or whole rice shells, Andes grass as well as vermiculites. Also, Asian grasses and plant and tree components may be added to the cotton.
Other objects and features of the present invention will become apparent from the following detailed description considered in connection with the accompanying drawing. It is to be understood, however, that the drawing is designed as an illustration only and not as a definition of the limits of the invention.
In the drawing there is illustrated a partial perspective view of a building wall according to the present invention.
Now turning to the drawing and particularly the left side thereof, there is shown an exterior or interior building wall 1 constructed from aerated or porous concrete blocks or ~2~3~5 04544-7/iY
bricks 2. The use of porous concrete bricks 2 permits very high dimensional accuracy for the exterior or interior wall 1. The exterior or interior wall 1 may be constructed in exact compliance with the specified construction dimensions in a way such that no later corrections are required. The surface 3 of the wall has joints 4 between the concrete blocks 2. For producing the wall covering, joints 4 are first covered by means of mortar or plaster 5 or a material based on aerated concrete granulate. The covering is used in order to hide joints 4 and prevent their visibility. The structured coating 6 is applied to surface 3 of the wall with the joints 4 covered as shown at reference numeral 5. The structured coating 6 covers the total wall surface 3 and serves both as a decorative coating and sound and heat insulation. Furthermore, protection against fire may be achieved to a high degree depending on the thickness of coating 6 applied to wall 1.
Turning now to the right side of the drawing, it is seen that the entire surface 3 of the wall may also be covered with a layer 5 consisting of a thin-bed plaster or mortar. This thin-bed plaster layer 5 has a thickness of about one to two millimeters. If desired, also a slurry may be applied.
Furthermore, layer 5 may be a thin plaster with a thickness of about two to three millimeters. This coating or layer 5 mainly ~ 32~ 0454~-7/jY
serves the purpose of covering the wall and mortar joints 4.
The structured layer 6 consisting of a mixture of fibers is then applied to said layer 5.
While two embodiments of the present invention have been shown and described, it will be obvious that many changes and modifications may be made thereunto without departing from the spirit and scope o~ the invention.

Now turning to the drawing and particularly the left side thereof, there is shown an exterior or interior building wall 1 constructed from aerated or porous concrete blocks or ~2~3~5 04544-7/iY
bricks 2. The use of porous concrete bricks 2 permits very high dimensional accuracy for the exterior or interior wall 1. The exterior or interior wall 1 may be constructed in exact compliance with the specified construction dimensions in a way such that no later corrections are required. The surface 3 of the wall has joints 4 between the concrete blocks 2. For producing the wall covering, joints 4 are first covered by means of mortar or plaster 5 or a material based on aerated concrete granulate. The covering is used in order to hide joints 4 and prevent their visibility. The structured coating 6 is applied to surface 3 of the wall with the joints 4 covered as shown at reference numeral 5. The structured coating 6 covers the total wall surface 3 and serves both as a decorative coating and sound and heat insulation. Furthermore, protection against fire may be achieved to a high degree depending on the thickness of coating 6 applied to wall 1.
Turning now to the right side of the drawing, it is seen that the entire surface 3 of the wall may also be covered with a layer 5 consisting of a thin-bed plaster or mortar. This thin-bed plaster layer 5 has a thickness of about one to two millimeters. If desired, also a slurry may be applied.
Furthermore, layer 5 may be a thin plaster with a thickness of about two to three millimeters. This coating or layer 5 mainly ~ 32~ 0454~-7/jY
serves the purpose of covering the wall and mortar joints 4.
The structured layer 6 consisting of a mixture of fibers is then applied to said layer 5.
While two embodiments of the present invention have been shown and described, it will be obvious that many changes and modifications may be made thereunto without departing from the spirit and scope o~ the invention.
