Wall dowel rod

The invention described here relates to a wall dowel rod made of wood, plastic or another material which Can be nailed or screwed and in masonry, prefabricated house parts or concrete cast can be walled in, poured in, concreted in or embedded. ( Illustration 1 )

The wall dowel rod can be subdivided into the resulting dowel sizes. The individual dowels are through incisions separated from each other. The incisions between the individual dowels are only made by an acute-angled connection interrupted which holds the dowels together. (Figure 2) This allows the dowel rod to be easily broken if necessary and subdivided into dowels of the required size.

On the top and / or bottom, the dowels are provided with longitudinal and transverse grooves so that a square or square pattern arises. (Figure 3)

The dowel created in this way engages deeply into his with its 30 squares or squares protruding on the bottom and top Fixing, for example, the mortar bed. A shifting or loosening is thereby even with the strongest use made impossible.

With the coordination of longitudinal and transverse grooves, the number is the lengthways and crossways milled indentations are not decisive, since far fewer grooves are sufficient Durability is achieved.

Rather, it is the principle to provide a wall plug with longitudinal and transverse grooves that is the subject of the invention is made.

To protect against moisture, mold and others Influences and for a better connection with mortar, lime or cement, the dowel can be treated with a tar-free special wood preservative are impregnated.

The possible uses of the wall dowel rods are very diverse. Wherever a permanently durable nailable or screwable fastening surface is required they are used.

For hinging door linings, "skirting boards and partition walls and the like she is to use. Gutters, stairs and suspended ceilings become light and easy thanks to their use permanently attached.

All deficiencies that occur in the previously used dowels are surprisingly easier with this invention Way eliminated. The never-related nailable stones

(Sawdust-cement binding) often shatter when hammered the hail. The replacement is associated with considerable expenditure of time and money. Dowels made of Sinschal or squared timber must be in place and the place of use can be sawn and fitted in ■ which appears to be very cumbersome. Also offer this at large Stress little hold.

Other types of dowels that are provided with conical recesses have the disadvantage that the conical recesses either are not sufficient for the adhesion in the mortar bed, so that a shift occurs with great stress or that the conical depressions are so deep that too little remaining effective mass is available for nailing stands. There are already known dowels that were provided with groove-like depressions. Because these depressions but were only known in the longitudinal direction, these dowels could not be attached on the head side because they gave only in the transverse direction! strength.

When connecting individual dowels, until now only transverse, continuous separating joints were known. This is true Easier to manufacture gives the connection of the individual dowels far less durability. Also the attack surface for the moisture is greater because the dowels are not impregnated at the break point.

The drawings attached for clarity show the features and advantages of the invention.
