Description of the embodiments

Shown and described, first with reference to FIG. 1 , A floor structure, in particular for a railcar, with a particular fan-shaped carrier 1. This can be formed for example as extruded hollow section.

The carrier 1 has integrally and uniformly formed material on top of a C-rail 2, which opens in the usual use state of the carrier 1 upwards.

Accordingly, the C-rail with respect to a cross-section, for example as shown in FIG FIG. 5 , the two opposite C-legs 3, 4, which are connected on the bottom side via a C-web 5. The latter is part of a support cover 6 in the illustrated embodiment. Accordingly, the C-rail 2 extends substantially above a through the support cover. 6 given horizontal plane.

The C-legs 3, 4 limit with respect to a cross-section according to FIG. 5 laterally the C-cavity. 7

In addition, the free end regions of the C-legs 3, 4 facing upward in the use state collar into the C-cavity 7, with an inner wall surface facing the C-cavity 7 the C-leg 3, 4 given free Kragmaß, which may correspond to about 0.7 to 2 times the C-leg material thickness. The end portions of the C-legs extend in an installed state essentially in a horizontal plane and / or in a plane which runs virtually parallel to the C-web 5.

This results in a the upper free edges of the C-leg 3, 4 associated opening dimension a of the C-rail 2, which is reduced by about one to two times the amount of material thickness in the C-leg 3, 4 with respect to the distance b of the facing wall surfaces of the C-legs 3, 4 in the C-cavity. 7

The vertical height c in the region of the C-cavity 7 between the C-cavity 7 facing surface of the C-bar 5 and the opening 8 on the underside bounding edge of the C-leg 3, 4, as may also be chosen to be smaller than the above-described distance b, so on about 0.5 to 0.85 times this distance measure b accordingly.

In the C-rail 2, an insulation layer can be used. In the illustrated embodiment, the insulation layer 9 is, as further preferred, a strand-like part with a uniform cross-sectional area over the length.

The insulation layer 9 may, for example, consist of an open-cell or closed-cell integral foam, as further particularly of a melamine resin foam.

Further, the insulation layer 9 is formed and adapted for insertion thereof in the longitudinal direction of the C-rail 2.

For this purpose, the insulation layer 9 initially has a form-fitting section 10 substantially filling the C-cavity, with a width b 'and a height c' considered perpendicular thereto, which are substantially adapted to the distance dimension b and the height c in the C-cavity 7 ,

As in particular from the cross-sectional representation in FIG. 3 to recognize, as further preferred, the corner formations of the form-fitting portion 10 may be rounded substantially adapted to the free cross-section of the C-cavity 7.

A support section 12 is connected via a waist section 11 formed on the upper side of the form-fitting section 10. Positive fit portion 10, waist portion 11 and support portion 12 are made integral and uniform material.

The support section 12 extends in the assignment position, for example according to the sectional view in FIG FIG. 5 , the upper side of the C-leg 3, 4, wherein the support portion 12 rests in the assignment position on the C-legs 3, 4.

The support portion 12 extends transversely to the longitudinal extent over a width dimension d 'which substantially corresponds to the width dimension d between the outwardly facing wall surfaces of the C-legs 3, 4.

Perpendicular to the width extension, a height of the support section 12 is given, which can correspond to approximately half the height c 'in the form-fitting section 10.

The waist section 11 connecting the form-fit section 10 to the support section 12 is formed with a width a 'given transversely to the longitudinal extension, which is preferably selected to be smaller than the opening dimension a of the rail-side opening 8. Thus, the width a' of the waist section 11 can be approximately 0, 7 to 0.9 times, further correspond to about 0.8 times the opening dimension a. When preferably with respect to the cross-section of the central arrangement of the waist portion 11 results in both sides of the same free spaces in the region of the rail-side opening 8. This leads to a facilitated Schiebeverlagerbarkeit the insulation layer 9 within the C-rail. 2

As further in particular from the detailed representation in FIG. 6 can recognize the height c 'in the region of the form-fitting portion 10 may be selected slightly smaller than the relevant height c in the C-cavity 7, so that in the upper side on the C-legs 3, 4 resting support section 12, the underside of the openings 8 limiting Edge of the C-leg 3, 4 in the both sides of the section 11 resulting free space resulting slot openings. This also contributes to a favorable shiftability.

The C-rail 2 is also used for example for fixing a floor layer 13 (or a wall layer). For this attachment, the insulation layer 9 may be interrupted with respect to their longitudinal extent. This discontinued region can be assigned a counter-fastening means 14 with an internal thread in the C-rail, which in the use position is supported on the underside on the edge of the C-legs 3, 4 surrounding the opening 8. With the interposition of a spacer 15, the floor layer 13 can be clamped using a helical fastener 16 against the carrier 1.

The load transfer is preferably carried out solely via the fastening training according to FIG. 7 , according to here according to the illustrated embodiment via the spacer 15 directly into the carrier first

According to the in the FIGS. 8 and 9 illustrated embodiment, the insulation layer 9 may be formed encompassing with respect to the C-rail 2, so in the arrangement position, the C-leg 3, 4 also outside overlapping.

The insulation layer 9 has in this case, in cross-section to the C-legs 3 and 4 adapted longitudinal slots 17. Thus, the longitudinal slots 17 of the embodiment shown are corresponding to the C-legs 3 and 4 in cross-section transverse to the longitudinal extent of the insulation layer 9 is substantially L-shaped, with facing L shorter limbs.
