Abstract

The composite stone with angled support and pressure surfaces is designed for the variants normal stone, foundation stone and cover stone. The gradation of the bearing and pressure surfaces ensures safe pressure transmission in the bearing joint. The dimensions of the composite stones may vary with a weight volume for hand or crane mounting.

field of use

The bond with abgew ngten supports and pressure surfaces can be used in Lardschafts- and civil engineering preferably for retaining walls or outer walls in reinforced soil and can dry mortar and laid on η.

Characteristic of the StamJf / S of the technique

Compound legs with worn-out supports and pressure surfaces are known from some examples of the prior art. Thus, DE-OS 3201 '592 describes a core gasket in dam structures for dams which consists of two spaced apart and opposite each other purely stacked composite stone η. The angled surfaces of these composite stones are executed without teeth od 'for r Abtreppungen. This stone was specially developed for the dam construction.

In WP 22841, a molded block is presented which has sides with beveled surfaces. A graduated FUCHEN offset does not show this stone.

A composite block for receiving high loads described in DE OS 3308512 has a step-shaped geometry in the opposite side surfaces, the edges of the steps running parallel to the pebble surfaces of the stone.

This stone is especially suitable for road construction only.

Generally, these known shaped stones have the following defects.

- low variability of use

- very specific purpose

- either crane or manual

- Relatively high cost of attachment of geotextile and Außenhautelerr ent

Object of the invention

The invention aims at a composite brick with angled; ι develop surfaces of various uses.

Explanation of the essence of the invention

The object of the invention is to provide an ally with angled supports and pressure surfaces whose geometric design ensures pressure transmission in the Lagerfugc «and can be made in different sizes with the same geometric solution.

According to the invention, the angled supports and pressure surfaces collide in a roof-like manner at an angle of approximately 90 ° and have a continuous groove at the WinkelstoS. Furthermore, the support and pressure surfaces are stepped in their middle.

In addition, the height of the bearing surface pitch may be greater than the height of the pressure surface gradation.

Due to the gradation of the supports and pressure surfaces of the composite blocks, pressure profiling in the bearing joint is ensured by means of profiling.

An important feature of the invention is that the composite brick has an angled bearing surface with an opposite parallel pressing surface in the normal direction.

embodiment

The invention will be explained in more detail with reference to an embodiment. The individual figures show

1: the isometric view of a composite brick in normal design FIG. 2: the isometric view of a composite brick as foundation stone FIG. 3: the isometric view of a composite brick as cover stone FIG. 4: cross cut through a composite brick in the variant as gutter stone FIG. Vertical section through a retaining wall made of composite bricks

According to FIGS. 1-3, the composite brick consists of the embodiments of normal stone, foundation stone and cover stone. The geometric shape of the normal stone is based on angled Auflagerfiächen having at their angle impact a groove in the longitudinal direction and opposite parallel pressure surfaces. The supports and dm. .Faces are graded in their middle. Optionally, in a particular embodiment, the height of the Abstufun j the support surface greater than the height of the gradation of Druckfläcnesein. The composite stone as a cover stone is: only equipped with a lower angled pressure surface. In the embodiment founding stone of the composite brick according to FIG. 2, the support surface is arranged roof-shaped with a central step on the block of stone. In Fig. 4, the possibility for realizing a flat gutter of Abdecksteinon the composite stone is set forth. Fig. 5 shows a retaining wall of composite stones as outer skin in reinforced soil. Depending on the area of use, the dimensions of the composite blocks may be different, depending on the area of use, with a weight volume for hand or crane dislocation. The execution of the stones can also be done in half-size, so that a total of 6 different stones can be used

 The composite stones are versatile:

- as a retaining wall system with backfill

- as outer skin in reinforced soil

- as Ricinenstein

- possible dry or mortar laying

The geometric formation of the composite blocks allows easy achievement of a dressing.

The profiling of the supports and pressure surfaces with a graduation ensures pressure transmission in the bearing joint.
