CONCRETE LUMP FOR STONE WALLS,
ESPECIALLY CLINKERS

The invention relates to a concrete lintel for stone walls, in particular Facing clinker.

For bridging recesses, doors or windows, as well as
so-called lintels made of concrete, "concrete lintels", 3.1s load-bearing beams for the masonry above are used as the lower limit of facing masonry. Such a concrete lintel has to bear the entire load of the wall section over its length
be dimensioned accordingly in terms of strength and statics.

Concrete lintels are particularly suitable as the lower boundary of facing masonry. Up to now, such facing walls have preferably rested on angle irons attached to the facades, which are subject to strong corrosion are exposed.

The present invention is based on the object of a beta fall to create that has a maximum of load capacity with a minimum of its necessary dimensions and especially with facing masonry enables a direct connection with the main wall.

The object set uiird is achieved according to the invention in that
at intervals of at least the length of a brick to be built on the concrete lintel at least to / from the top of the concrete

7812107 08/17/78

Lintel protruding vertically and into the joints or openings of the
There are plug-in stops to be walled up,
whose height is not greater than the height of the assigned bricks !!

The stops projecting upwards form in the longitudinal direction of the concrete lintel effective abutments that help reduce deflection j

to counteract the Bstonfall and thus its strength
to increase the load-bearing capacity of the first brick layer. |

Above all, the invention offers the possibility of a rational approach

production and thus a simplification and acceleration of masonry work, especially the facing work on the job site.

Details of the invention are given in the subclaims

and explained in more detail in the drawing, for example.

Show it:

1 shows a side view of a concrete lintel with a clinker facing and a clinker overlay,
ν Fig. 2 shows a cross section along the line H-II in Fig. 1 and

3-5 cross-sections similar to FIG. 2 for modified embodiments of a concrete lintel according to the invention.

1 and 2 show a concrete lintel 1 with a rectangular cross-section and a multiple reinforcement 2 in the longitudinal direction. On its front side, the concrete lintel has a facing made of clinker straps 3. |

I At intervals of at least one length of clinker brick is perpendicular to the t

Longitudinal direction of the concrete lintel 1 each one from the top 4 of the I.

Concrete lintel 1 perpendicularly protruding stop 5 in the form of a Ring or bracket arranged, which is provided so that it is in a Joint between two stones 6 to be walled up on the concrete lintel protrudes. Its height is not greater than the height of the wall to be walled up well 6.

With a weight load on the concrete lintel 1 by the above The masonry 6 acts on the stops 5 on both sides The compressive force of the stones 6 stabilizes and increases the load-bearing capacity of the concrete fall.

According to an embodiment according to FIG. 3 are closed Rings 5 are provided as stops that are connected to the reinforcement 2 e.g. by wiring or welding.

The embodiment according to FIG. 4 looks at corresponding intervals Blind holes arranged in the concrete lintel 1, possibly also bushings 7, into which the legs 8 of U-shaped brackets 5 'can be inserted. These The embodiment has the advantage that the bracket can be inserted into the concrete lintel 1 at any point within a hole spacing provided are. This means that storage is easier and there is less risk of damage, especially during transport.

In a further embodiment, the stops consist of perpendicular standing T or L profile pieces 5 "or sheets that are between the Reinforcement strands 2 are anchored in the concrete lintel 1.

The facing 3 of the concrete lintel 1 is not absolutely necessary. It is only essential that the stops 5 engage in joints or openings 3 of the bricks to be walled up. So it is also possible

7812107 08/17/78

to design the stops as vertically standing pins or tenons, those in the joints of the bricks 6 or in cavities in the bricks 6 intervene yourself, e.g. if these are hollow bricks, hollow blocks or similar.
