## Abstract

An anti-fall safeguard for persons includes a supporting base with which the anti-fall safeguard can be set up on an underlying surface formed of individual concrete slabs. The concrete slabs are provided with upwardly projecting iron reinforcing elements and with an anchor mast system which is connected to the supporting base. Personal protective equipment is fastened to the free, upper end of the anchor mast system. In order to securely fasten the anti-fall safeguard on an underlying surface, two or more cable safeguards are provided, which can be brought into connection with the iron reinforcing elements of the concrete slabs. The cable safeguards can be tensioned and the supporting base is immovably secured on the underlying surface by the tensioning of the cable safeguards.

## Claims

### Claim 1

An anti-fall safeguard for persons, the anti-fall safeguard comprising:
an underlying surface formed of a concrete slab (40) equipped with upwardly-projecting iron reinforcement elements (41);
a separate support base (1) for setting-up the anti-fall safeguard on said underlying surface;
an anchor mast system connected to said support base (1), said anchor mast system having a free, upper end for attachment of an item of personal protective equipment (PPE);
upwardly-projecting upright columns (5, 6, 7, 8);
at least two tensible cable safeguards (50, 51, 52, 53) configured to be brought into connection with said iron reinforcement elements (41) of said concrete slabs (40); and
cable winches (15, 16, 17, 18) directly or indirectly connected to said support base (1) by said upwardly-projecting upright columns (5, 6, 7, 8) for tensioning said cable safeguards (50, 51, 52, 53) and securing said support base (1) by immovably tensioning said cable safeguards (50, 51, 52, 53) on said underlying surface.

### Claim 2 (depends on 1)

The anti-fall safeguard according to claim 1, which further comprises a separate base plate (10) configured for setting-up and fixing said support base (1) on said base plate (10), said cable safeguards (50, 51, 52, 53) with said cable winches (15, 16, 17, 18) and said upright columns (5, 6, 7, 8) being part of said separate base plate (10).

### Claim 3 (depends on 2)

The anti-fall safeguard according to claim 2, wherein said base plate (10) is formed of a plurality of polygonal or circular annular ring segments (30, 31), and radially running connecting braces (35, 36) fixedly connect said ring segments (30, 31) to each other.

### Claim 4 (depends on 3)

The anti-fall safeguard according to claim 3, wherein said ring segments (30, 31) are disposed at a radial distance from each other, said ring segments (30, 31) have downwardly-directed surface sections forming a footprint for said support base (1), and said ring segments (30, 31) have upper sides on which said support base (1) is placed.
