Height-adjustable hollow body for supporting plate-shaped coverings

The invention relates to a height-adjustable hollow body according to the preamble of claim 1.

Such hollow bodies enable the laying of flat ·■' plate-shaped coverings, for example on an uneven

Screed surface. Liquids such as rainwater, which |

penetrate into the panel joints and can occur in the space between f;

Screed and slabs drain away. When laying slabs |

a height adjustment of the hollow body in as f as possible

small steps desired. &

Height-adjustable hollow bodies of the generic type
are known. The height adjustment is carried out
by placing additional discs (CH-PS 522
799, 1972).

These discs are placed loosely and can therefore |

by lateral thrust forces or when laying the |

Plates slip. They also increase the number of &iacgr;

Use components»

The invention is based on the aim of creating height-adjustable hollow bodies for supporting plate-shaped coverings, which are stable against lateral thrust forces and consist of only a few components.

This object is achieved according to the invention in a hollow body of the generic type with the means specified in the characterizing part of claim 1. According to the basic idea of the solution according to the invention, support segments of one part which run obliquely to the support planes and have teeth perpendicular to these planes engage adjustably in notches of the other part.

The upper and lower parts of the hollow body are preferably cylindrical. The support segments advantageously run concentrically to the cylinder axis, preferably along the circumference. The height is adjusted by turning the upper and lower parts against each other. Stability can be increased if the upper and lower parts are each provided with support segments of the same design arranged in a sawtooth shape along the circumference.

The upper part is preferably provided with four diametrically opposed joint dividers on its support plane, which are advantageously connected to it by predetermined breaking points. If required, e.g.

1 I · ■ < ·

If the joints are changed or the edges are laid out, they can be removed or simply broken away. The lower part can be provided with openings on its support level, the arrangement of which is the same as the arrangement of the joint dividers and which are preferably circular, with their diameter preferably being matched to the length of the joint dividers. This means that two or more hollow bodies can be placed on top of one another to bridge larger height differences.

Further height adjustment can also be achieved if a hollow body is placed on a washer. The lower part can have a central recess on its support surface into which the central pin of the washer engages.

The advantages that can be achieved with the invention are that the hollow body can be adjusted in fine increments in a single movement, is stable against lateral thrust forces, and consists of only two components. Furthermore, by placing two or more hollow bodies on top of each other, larger height differences can be bridged and further height adjustment can be achieved by placing a hollow body on a washer.

A preferred embodiment of the hollow body is shown in the drawing and is described in more detail below.

Figure 1 - a partial plan view of concrete slabs with the hollow body according to the invention,

Figure 2 - a side view of the arrangement according to Figure 1,

Figure 3 - a perspective exploded view of the hollow body/ and

Figure 4 - a longitudinal section along the line IV^IV of Figure 3.

Figure 1 shows concrete slabs 6 resting on a cylindrical hollow body. The concrete slabs 6 are separated by four diametrically arranged joint dividers 3.

From Figure 3 it is clear that the hollow body consists of an upper part 1 and a lower part 2, with the former being pushed over the latter. The concrete slabs 6 are supported by the support plane of the upper part 1, whereas the support plane of the lower part 2 rests on the screed 7. The side surface of the upper part 1 has the shape of a cylinder shell, which has sawtooth-shaped pin grooves 11.

In Figures 3 and 5, the upper part 1 is separated from the lower part 2. The support segments 4 of the lower part 2 and the support segments 4 ¹ of the upper part 1 are of the same design and are arranged in a sawtooth shape along the circumference so that when the two parts are assembled

interlock. The support segments 4 ¹ of the upper part 1 are located on the inside of its side wall opposite the recesses 11. The support segments 4 of the lower part 2 form its side wall and are connected internally via connecting webs 17 to reinforcing segments that are also sawtooth-shaped. When the hollow body is plugged together with another hollow body, the joint dividers 3 engage in the circular openings ü with which the lower part 2 or 2' is provided on its support plane. The lower part 2 can be placed on a washer 15, with the central pin 16 of the washer 15 engaging in a central recess that the lower part 2 has on its support plane.
