Abstract

A spacer disk for the laying of construction plates on a rigid base has an upper surface and a lower surface and formed with radial running raised portions arranged on the upper surface thereof and defining a joint width of the plates. The spacer disk is of ring form, having a center opening and formed on the lower surface at a region thereof lying and following opposite the raised portions, respectively, two linear running recesses extending across the width of the ring.

Claims

1. A spacer for the laying of construction plates on a rigid base, comprising a spacer disk having an upper surface and a lower surface and formed with radially running raised portions arranged on said upper surface thereof and defining a joint width of said plates, said spacer disk being of ring form, having a center opening and being formed in said lower surface in a region thereof lying and fOllowing opposite to said raised portions, respectively, with two linearly running recesses extending across the width of said ring form.

2. The spacer defined in claim 1, wherein said recesses further constitute separation joints, for separating said disk into segments.

3. The spacer defined in claim 2, wherein said disk is of elastic material for the purpose of sound proofing.

4. The spacer defined in claim 2, wherein said raised portions of said disk are radially extending ribs.

5. The spacer defined in claim 2, wherein said disk is formed as a circular ring.

6. The spacer defined in claim 2, wherein said recesses extend radially in said disk.

7. The spacer defined in claim 6, wherein a pair of said recesses in said lower surface of said disk are disposed on both sides of each of the corresponding raised portions on the upper surface of said disk.

8. A spacer disk and support disc combination for laying of construction plates on a rigid base, comprising a spacer disk having an upper surface and a lower surface and formed with radially running raised portions arranged on said upper surface thereof and defining a joint width of said plates, said distance disk being of ring form, having a center opening and forming in said lower surface in a region thereof lying and following opposite to said raised portions, respectively, two linearly running recesses extending across the width of said ring form, and a support disk, said lower surface of said distance disk being laid on said support disk.
