A floor structure for events having - two side profiles which are situated opposite and parallel to one another, - two end profiles which are situated opposite and parallel to one another and, with the side profiles, form the periphery of a rectangle with open corner regions, wherein the side profiles and/or end profiles are supportable on carrier profiles for forming, for example, a platform or a podium, - a floor covering, in particular a laminated wood floor covering, which is connected to the end profiles and the side profiles, - corner connector profiles which connect a side profile to an end profile in a load-bearing manner in the respective corner region, - corner cap devices which form the open corner region into a closed corner unit, whereby the corner cap device includes a plurality of separate components: - a base plate which is connectable to the corner connector profile or the side/end profile (12, 14) and covers the outside contour of the corner connector profile and the free front end regions of the side profiles and end profiles (12, 14), - a corner cap unit which is connected releasably to the base plate and a separate attachment unit insertable from the top in corner cap unit so that the open end region is upwardly concise closed by the floor covering, - the corner cap unit comprises a substantially triangular periphery, the hypotenuse of which faces the corner connector profile and is connected releasably to the same and the cathetuses of which form walls which are arranged tapering toward one another at an angle of 90°, - the hypotenuse of the corner cap unit extends substantially in the longitudinal direction of a chamfer which is integrally formed in the corner region of the floor covering. - two side profiles which are situated opposite and parallel to one another, - two end profiles which are situated opposite and parallel to one another and, with the side profiles, form the periphery of a rectangle with open corner regions, wherein the side profiles and/or end profiles are supportable on carrier profiles for forming, for example, a platform or a podium, - a floor covering, in particular a laminated wood floor covering, which is connected to the end profiles and the side profiles, - corner connector profiles which connect a side profile to an end profile in a load-bearing manner in the respective corner region, - corner cap devices which form the open corner region into a closed corner unit, whereby the corner cap device includes a plurality of separate components: - a base plate which is connectable to the corner connector profile or the side/end profile (12, 14) and covers the outside contour of the corner connector profile and the free front end regions of the side profiles and end profiles (12, 14), - a corner cap unit which is connected releasably to the base plate and a separate attachment unit insertable from the top in corner cap unit so that the open end region is upwardly concise closed by the floor covering, - the corner cap unit comprises a substantially triangular periphery, the hypotenuse of which faces the corner connector profile and is connected releasably to the same and the cathetuses of which form walls which are arranged tapering toward one another at an angle of 90°, - the hypotenuse of the corner cap unit extends substantially in the longitudinal direction of a chamfer which is integrally formed in the corner region of the floor covering.
