In combination with fig. 1, the utility model provides a bridge expansion joint structure, which comprises a concrete structure 50, a reinforcing steel structure 40, F-shaped steel 10 and a supporting component 20, wherein the bridge expansion joint structure is arranged between two fixed building structures, the edges of the two building structures are provided with the concrete structure 50, the reinforcing steel structure 40 is led out from the concrete structure 50, the reinforcing steel structure 40 is welded with the F-shaped steel 10, a pouring sealant structure 30 filled between the two F-shaped steel 10 is sealed, after the two fixed building structures are stretched and contracted due to cold and hot vibration factors, the pouring sealant structure 30 can compensate the stretching amount, the pouring sealant structure 30 is a consumable product, after the pouring sealant is worn, repairing is needed, the pouring sealant is refilled, and in order to facilitate the repairing, the supporting component 20 is arranged between the two F-shaped steel 10, so that the supporting effect on the pouring sealant structure 30 is realized, and meanwhile, the stretching action between the two F-shaped steel 10 is not influenced.

As shown in fig. 1-2, the F-shaped steel 10 includes a first transverse plate 11 and a second transverse plate 13, the length of the first transverse plate 11 is smaller than that of the second transverse plate 13, the supporting member 20 is arranged to be capable of entering into the upper end face of the second transverse plate 13 from between the two first transverse plates 11, the upper end face of the supporting member 20 forms a supporting face, and a pouring sealant structure 30 is arranged on the supporting face.

The first transverse plates 11 and the second transverse plates 13 are connected through the connecting plates 12, and as the gap between the first transverse plates 11 is large and the gap between the two second transverse plates 13 is small, the supporting part 20 is easy to put in from the gap between the first transverse plates 11 and is placed on the upper end face of the second transverse plates 13, and the supporting part 20 is kept at a fixed height position.

As shown in connection with fig. 4, the support member 20 includes a first portion and a second portion (a left half and a right half of the support member 20 are shown in connection with the drawings), and the first portion and the second portion include a first connection plate 21, a second connection plate 22, a third connection plate 23, and a fourth connection plate 24 that are connected to each other.

Wherein the first connecting plate 21 and the third connecting plate 23 are parallel, the second connecting plate 22 is parallel to the inner end surface of the first transverse plate 11, and the fourth connecting plate 24 comprises a plurality of sheet structures which are distributed in parallel.

In an alternative embodiment, the supporting member 20 is a stainless steel plate structure, and the first connecting plate 21, the second connecting plate 22, the third connecting plate 23, and the fourth connecting plate 24 are formed by bending the stainless steel plate structure, wherein bending lines are shown by dashed lines in fig. 5.

In particular, the fourth webs 24 of the first and second portions of the support member 20 are staggered. Thus, when the fourth connecting plates 24 of the first and second portions are engaged with each other, they are alternately engaged with the lower portion of the supporting member 20 to form an elastic supporting structure.

Preferably, the stainless steel plate has a thickness of 1-2mm.

As shown in connection with fig. 2-3, the length of the fourth connection plate 24 is greater than the length of the third connection plate 23.
