Title of the Invention Exterior Liner Shell Field of application of the invention

The invention relates to an outer attachment shell made of hand-assembled precast elements for retrofitting to outer walls.

Characteristic of the known technical solutions

Facade structures are already known, which are arranged due to lack of thermal insulation or as a result of Durchfeuchtungserscheinungen, subsequently to existing outer walls. In building practice, this application has been succeeded by ventilated façades whose outer facing shells consist of brick clinkers, natural stone or cast stone slabs and which have a thickness of the thermal insulation layer of at least 80 mm. These constructions require due to their relatively high weight, a material-intensive substructure, 'must be made of corrosion-resistant material. Because of the possible unevenness in the exterior walls to be rehabilitated, the substructures must be equipped with adjusting devices that increase the cost of the outer shells due to their cc-nplizierten structure. Another disadvantage of the known façades made of natural or artificial stone slabs is the separation of the façade elements at openings and building edges. Since artificial stone slabs made of concrete or natural stone slabs are relatively hard, a high time and cost is required when separating these components.

Object of the invention

It is an object of the invention to provide a Außenvorsatsschale, which can be arranged with cincM low material and labor cost and high quality to the outer wall to be rehabilitated.

Explanation of the essence of the invention

The invention has for its object to develop a foreign intent, with their help facades that no longer meet the structural or physical requirements, in high Maßgonauigkoit, with

2 8 S 6 2 6

a small proportion of corrosion protected iMataliunterkonstruktionen and fasteners can be rehabilitated at the same time improved thermal insulation value and a simplified cutting of the surface elements to adapt to building footings and edges.

According to the invention, this object is achieved in that the surface elements, which consist of hydrophobically finished handmontagefähigen gypsum elements are provided on their Rückseihen with cassettes, in the upper end obliquely downwardly directed U-shaped curved eyelets are arranged, which protrude into the cassette. The eyelets accommodate hangers made of corrosion-protected wire in the form of a lower loop. Brackets, which also consist of corrosion-coated wire, are arranged in the upper part of the surface elements insertable in bow openings and protrude into the groove in the base area of the surface elements mounted above. On Jen upper edges of the back of the surface elements are mounted attachable together with the brackets angle. On the vertical part of the angle disc-shaped caps are fixed, which have in their center sleeves with an internal thread, are screwed in der.an spacers in the form of preferably round head screws. The brackets, caps, sleeves and spacers are made of plastmatorial. Also made of plastic material are screws and nuts, which are used in a wet dowel 12 from a strong swelling during the setting process mortar, with a part of the screwdriver, protruding from the outer wall. After arranging the thermal insulation, the groove of the surface element has been placed on the bracket of the surface element mounted underneath, fixed the angle with arigeformter cap and the spacer by attaching the bracket in the stirrup openings on the surface element, woboi the surface element by screwing in or unscrewing the spacer within the Sleeves is aligned to Schnurflucht. Thereafter, the free ends of the hangers are locked on the outside wall by means of reclosing latches around the protruding parts of the screws. Instead of the wet dope, eiiu may also be used; The drill hole has been inserted into the outer wall using special drill gauges. In the oblique bore, a rod is preferably introduced dry. The wraps of the hangers, which form an acute to right angle to the longitudinal axis dos States, are then secured by a split pin on the head of the rod against slipping. The surface elements are adapted in the area of the building openings and to the canton by sawing on the laying sliver.

embodiment

The invention will be explained in more detail using an exemplary embodiment. In the accompanying drawings show:

FIG. 1 shows a vertical section through the outer attachment shell according to the invention,

FIG. 2 shows a horizontal section according to FIG. 1, FIG. 3 shows a view according to FIG. 1 and FIG. 2,

Figure 4: a vertical section with an obliquely downwardly introduced into the outer wall bore.

The surface elements 1, which consist of hydrophobically equipped hand-mountable gypsum elements are provided on their backs with cassettes 2, in the upper termination obliquely downwardly directed U-shaped eyelets 6 are arranged, which protrude into the cassette 2. The eyelets 6 take hanger 7 from corrosion-protected wire in the form of a lower loop 8. Hill 5, which are also made of corrosion-resistant wire, are arranged in the upper part of the surface elements 1 inserted into bow openings 4 and protrude into groove 3 in the foot region of the surface elements 1 mounted above. On the upper edges of the back of the surface elements 1 5 angles are attached attachable together with the brackets. On the vertical part of the angle 17 disc-shaped caps 19 are fixed, which have in their center sleeves 18 with an internal thread, in which spacers 16 are screwed in the form of preferably round head screws. The angle 17, caps 10, sleeves 18 and the spacers 16 are made of plastic material. Also made of plastic material are screws 10 and 11 cutters, which are dowelled in a Naßdübol 12 from a strong swelling during the setting process mortar, with a portion of the screws 10 protrudes with nuts 11 from the outer wall 13. After arranging the insulation 14, the hat 3 dos surface element 1 are placed on the temple 5 of the surface element mounted below 1, the angle 17 with the cap 19 and the spacer 16 by attaching the bracket 5 in the bow holes 4 attached to the surface element 1, wolxji the surface element 1 is aligned by inserting or unscrewing the spacer 16 within the sleeve 10 by string. Thereafter, the free ends of the hangers 7 have been locked by wraps 9 around the protruding screws 10 on the outer wall 13. FIG. 1 shows a further variant of the element attachment. In this case, instead of dos iiaßdübels 12 an oblique bore 22 in the Außenv / and

brought in. A rod 20 is preferably introduced dry into the oblique bore 22. The wraps Gn 9 of the hanger 7, which form an acute to right angle 23 to the longitudinal axis of the rod 20 are secured by a splint 21 at the head of the rod 20 against slipping. The thickness of the cap 19 and the angle 17 corresponds to the width of the cavity of the rear ventilation 15 between the thermal insulation 14 and the back of the surface elements 1. The surface elements 1 according to the invention can be adapted in the area of the edges of the building, the windows and doors by sawing on the laying tether earth. The separation of the surface elements 1 of hydrophobic gypsum is easily possible because of their low hardness. Since the surface elements 1 are only dry mounted and verschrödelt without the usual adhesive, rivet or screw on the protruding screws 10 or rods 20 by means of wraps 9 and the vaults of the spacer 16 ajar against the outer wall 13 v / earth, is assuring a high work productivity during assembly, while at the same time improving the working conditions, because additional aggravating operations with special machines and special materials for fixing the surface elements 1 are not required. The construction of the invention also contributes to the material and energy cost savings, since due to the statically favorable system of suspending and supporting using the hangers 7 and the spacer 16 only a relatively thin loaded on train corrosion-protected wire is required and still the distance between the outer wall 13th and the backs dor surface elements 1 can be substantially increased without the wire cross section has changed v / ground. As a result, the layer thickness of the 'thermal insulation 14 can be easily increased for effective full thermal insulation of the building. The formation of thermal bridges is greatly reduced, since the direct connections of the good heat-conducting hangers 7 between the surface elements 1 and the outer wall 13 by the screws 10 _r or by the rods 20, preferably made of the poorly heat-conductive plastic material or the like, are interrupted , This also applies to the supporting elements of the spacers 16, which can also be made of plastic material because of the de. Static favorable suspension system and Abstützons the Außenvorsatzschale. Particularly advantageous is the attachment of the hangers 7 on the rods 20, as by the oblique holes 22, the faster insertion of the rods 20 in the dry process, without mortar for the dowel 12 can be guaranteed.
