Description
SPECIFICATION
A wall tie
The invention relates to a wall tie for bridging the space between a loadbearing wall (e.g. of
concrete or brickwork) and a front wall situated in front of the said wall, for instance between the
inner and outer skins of a cavity wall.
Various systems of retaining and anchoring
means for bridging the space between a load
bearing brickwork and a front wall situated in front of it are known. According to their
application, i.e. whether the front wall is secured subsequently or whether it is built subsequently
at a distance from the loadbearing brickwork, the
anchoring means differ in principle in their design.
The common feature of all these systems is that the space between the loadbearing wall and the front wall is bridged while the space may either be a free air space or contain an insulation layer. The
part of the tie which bridges this space is consequently by the displacement of the dew point region particularly suitable for collecting
humidity condensating as dew. There is a danger that condensate formed in this way may travel on the wall of the tie bridging the layer of air into the front or rear brickwork and produces there wet places. In order to prevent this for instance drip discs are positioned on ties made of wire (German
Patent Specification 20 26 139). Ties of this embodiment with drip discs, have, however, the disadvantage that they cannot be used if the front wall is built subsequently, and in addition the drip discs represent additional expenses.In order to prevent penetration of dampness, when wire ties are used, along the bridge region, it is known to provide in this area a kink (German
Offenlegungsschrift 30 07 771). This wall tie has also the disadvantage that it is not suitable for subsequent securing.
A tie known for subseqeunt securing of front walls-which is used in the so-called insert assembly-consists of a cylindrical sleeve the wall of which is provided with holes. Fixing of this tie in brickwork or in the front wall is achieved in that the sleeve, which is slit in both its end regions, is widened by extendable nuts situated on the anchoring bolt. For guiding the condensate off, the anchoring bolt surrounded by the sleeve is provided with a washer on which the condensate may drop off. Although this tie is suitable for subsequent securing, additional costs are caused by the need for the washer. There are also additional expenses with a further operation during completion of the tie.
The aim of the invention is to provide means for the drainage of the condensate both for securing ties and for wire ties, without significant additional costs for the tie.
This aim is achieved according to the invention in that the portion of the tie which, in use, bridges said space is provided with a peripheral groove and/or bead. By the provision of this groove and/or bead are advantageously obtained means which effectively prevent exchange of condensate between the front wall and the loadbearing brickwork without the need for an additional element. The peripheral groove may be made advantageously and simply both in wire ties and sleeve ties.
The metal sheet sleeve of sleeve ties is usually made such that the inner width is slightly smaller than the diameter of the bolt. If the peripheral groove is made as a corrugation, a drop forming element is conveniently produced not only for the sleeve but also for the bolt. This is achieved in that the inner diameter of the corrugation is smaller than the outer diameter of the bolt so that after insertion of the bolt the corrugation bears onto the thread with a small pre-tension. Due to the springiness of the sleeve the user does not experience any difficulties during fixing of this securing tie.
This invention will now be explained, by way of example, with reference to the accompanying diagrammatic drawings, in which:
Fig. 1 is a sleeve tie according to the invention in side elevation,
Fig. 1 A shows detail "X" from Fig. 1 on a larger scale,
Fig. 2 is a sleeve tie according to Fig. 1 in a different embodiment,
Fig. 3 is a wire tie according to the invention in perspective view, and
Fig. 3A shows detail "Y" from Fig. 2 on-a larger scale.
In the drawing the reference 1 indicates a wall or a loadbearing skin of a building which is hereinafter called "mounting wall 1". Instead of the illustrated wall of reinforced concrete any kind of brickwork may be used in principle as a loadbearing skin. Spaced therefrom is situated as a facing brickwork a facing wall (a facade) indicated as a whole by the reference 2. Space 3 between the mounting wall 1 and the facing wall 2 is in the embodiment according to Figs. 1 and 2 in the form of an air shaft. Also an insulating layer 4 may be situated in the space 3, as shown in Fig.
3.
Fig. 1 shows subsequent securing of an existing facing wall 2 to the mounting wall 1 by means of a securing sleeve tie 5. The tie 5 consists substantially of a sleeve 6, an anchoring bolt 7 and two expanding cones 8. The wall 9 of the sleeve is provided with holes 10.
As is further apparent from the drawing, particularly from Fig. 1A, the wall 9 of the sleeve 6 has in the region where it spans the space 3, or between the two end regions 11 of the sleeve 6, a concave groove 12. Condensate formed on the wall 9 can therefore drop off in this regions is shown, by way of example, by the drop 13-and is effectively prevented from travelling from the facing wall 2 to the mounting wall 1 or vice versa.
The peripheral groove 12 in Fig. 2 is made deeper so that a corrugation 14 was formed. The inner diameter of the corrugation 14 is smaller than the outer diameter of the anchoring bolt 7.
When the anchoring bolt 7 is inserted into the sleeve 6 the sleeve is slightly pre-tensioned so that the corrugation 14 snugly fits the thread of the anchoring bolt 7. In this way is advantageously formed a drop-forming region for the wall 9 of the sleeve 6 and for the anchoring bolt 7 without an additional element being needed.
Fig. 3 shows a wall tie 15 made from a wire the ends of which are bent to extend in opposite directions, so that the tie 1 5 is approximately Zshaped. Wall ties of this embodiment are made of a single piece of wire and are used when the facing wall 2 is made simultaneously with the mounting wall 1 or if the facing wall is built subsequently. In order to prevent the condensate from travelling into both wall regions or in order to enable dropping off of the condensate, a peripheral groove 18 is made in the wall 16 of the central stem 17 of the wall tie 15. The reference 19 indicates a drop of water. The peripheral groove 18 is preferably made by rolling so that beads 20 (Fig. 3A) are formed from which condensate drops.
By the provisions or embodiments according to the invention is achieved, without additional elements, that all humidity, which creeps along the wall 9, 10 of the tie 5 or the wall 16 of the central stem 17 of the tie 1 5, drops off due to gravity as soon as the humidity or condensate try to flow pass the groove 12, 1 8, the corrugation 14, or one of the beads 20.
It will be understood that many modifications of the described and illustrated embodiments are possible: so for instance the grooves need not be curved in cross-section, the sleeve need not be cylindrical and the arrangement of two beads defining one groove shown in Figs. 3 and 3A may be used in any of the other embodiments.
