A main floor element is disposed between the two side sills. An energy store is disposed under the main floor element. A crossmember element is disposed on an upper side of the main floor element and extends in the transverse direction of the vehicle between the two side sills. A hollow cross section of the crossmember element is delimited upwardly in the vertical direction of the vehicle by an upper flange of the crossmember element and is supplemented by the main floor element to form a closed hollow cross section. A reinforcement element is attached to the main floor element via a first attachment region and is attached to the upper flange via a second attachment region and a third attachment region. ## Claims ### Claim at position 1 -10. (canceled) ### Claim 11 A floor structure for a body (10) of a vehicle, comprising: two side sills (20, 22) spaced apart from each other in a transverse direction of the vehicle (y); a main floor element (24) which is disposed between the two side sills (20, 22); an energy store (26) disposed under the main floor element (24) in a vertical direction of the vehicle (z) for storing electrical energy and/or a fuel; a crossmember element (32) which is disposed on an upper side (30) of the main floor element (24) facing upwards in the vertical direction of the vehicle (z) and away from the energy store (26) and which extends in the transverse direction of the vehicle (y) between the two side sills (20, 22), wherein a hollow cross section (34) of the crossmember element which is open downwardly in the vertical direction of the vehicle (z) and is delimited upwardly in the vertical direction of the vehicle (z) by an upper flange (36) of the crossmember element (32) is supplemented by the main floor element (24) to form a first closed hollow cross section (38); and a reinforcement element (46), wherein the reinforcement element (46) extends in the transverse direction of the vehicle (y) at least over a partial region of the crossmember element (32); wherein the reinforcement element (46) is attached to the main floor element (24) via a first attachment region (A1) and is attached to the upper flange (36) via a second attachment region (A2) and a third attachment region (A3) which are disposed at a distance from each other in the longitudinal direction of the vehicle (x). ### Claim 12 A floor structure for a body (10) of a vehicle, comprising: two side sills (20, 22) spaced apart from each other in a transverse direction of the vehicle (y); a main floor element (24) which is disposed between the two side sills (20, 22); an energy store (26) disposed under the main floor element (24) in a vertical direction of the vehicle (z) for storing electrical energy and/or a fuel; a crossmember element (32) which is disposed on an upper side (30) of the main floor element (24) facing upwards in the vertical direction of the vehicle (z) and away from the energy store (26) and which extends in the transverse direction of the vehicle (y) between the two side sills (20, 22), wherein a hollow cross section (34) of the crossmember element which is open downwardly in the vertical direction of the vehicle (z) and is delimited upwardly in the vertical direction of the vehicle (z) by an upper flange (36) of the crossmember element (32) is supplemented by the main floor element (24) to form a first closed hollow cross section (38); and a reinforcement element (46), wherein the reinforcement element (46) extends in the transverse direction of the vehicle (y) at least over a partial region of the crossmember element (32); wherein the reinforcement element (46) reinforces the crossmember element (32) and is disposed on the crossmember element (32) from an outside, wherein the crossmember element (32) and the reinforcement element (46) have a first connection point on the upper flange (36) and a second connection point in a region between the upper flange (36) and the main floor element (24), wherein a first closed hollow cross section (38) is delimited by the crossmember element (32) and the reinforcement element (46). ### Claim 13 (depends on 11) The floor structure according to claim 11, wherein the first attachment region (A1) and the second attachment region (A2) are at least partially offset from each other in the longitudinal direction of the vehicle (x). ### Claim 14 (depends on 11) The floor structure according to claim 11, wherein the second attachment region (A2) is disposed at least partially in front of the first attachment region (A1) in the longitudinal direction of the vehicle (x) and the third attachment region (A3) is disposed at least partially behind the first attachment region (A1) in the longitudinal direction of the vehicle (x). ### Claim 15 (depends on 11) The floor structure according to claim 11, wherein the crossmember element (32) has two side flanges (42, 44) via which the first closed hollow cross section (38) is delimited on both sides in the longitudinal direction of the vehicle (x). ### Claim 16 (depends on 12) The floor structure according to claim 12, wherein the crossmember element (32) has two side flanges (42, 44) via which the closed hollow cross section (38) is delimited on both sides in the longitudinal direction of the vehicle (x). ### Claim 17 (depends on 15) The floor structure according to claim 15, wherein the reinforcement element (46) is attached to at least one of the two side flanges (42, 44) via a fourth attachment region (A4). ### Claim 18 (depends on 11) The floor structure according to claim 11, wherein the reinforcement element (46) has a hollow cross section (50) which is open upwardly in the vertical direction of the vehicle (z) and which is supplemented by the upper flange (36) to form a second closed hollow cross section (52). ### Claim 19 (depends on 12) The floor structure according to claim 12, wherein the reinforcement element (46) has a hollow cross section (50) which is open upwardly in the vertical direction of the vehicle (z) and which is supplemented by the upper flange (36) to form a second closed hollow cross section (52). ### Claim 20 (depends on 11) The floor structure according to claim 11, wherein the energy store (26) is at least partially covered by the two side sills (20, 22) outwardly on both sides in the transverse direction of the vehicle (y). ### Claim 21 (depends on 12) The floor structure according to claim 12, wherein the energy store (26) is at least partially covered by the two side sills (20, 22) outwardly on both sides in the transverse direction of the vehicle (y). ### Claim 22 (depends on 11) A body (10) for a vehicle, comprising: the floor structure (14) according to claim 11.
